Scipedia content — Fri, 31 Mar 2017 14:19:28 +0200

coneval s official methodology for measuring multidimensional poverty (ommmp ) is critically evaluated, which underestimates poverty, and is contrasted with the lpmm . It is shown that in Mexico: 1) incidence of poverty (h ) in 2014 is higher than in 1977, 2) the number of poor (q) between 1992 and 2014 grew both in the lpmm as in the dimensions of income and ubn (Unsatisfied Basic Needs), 3) by removing ommmp s word play act to separate ‘vulnerable’ from ‘poor’, the deprived population is similar in both methods, 4) there is a big contrast between stagnation of q with one or more social deprivations in ommmp and the significant growth of q (ubn ) in the lpmm, 5) between 2006-2014 not only H, but the intensity (I) of poverty, the equivalent incidence (hi ) increased, 6) there were strong changes in the social pyramid:dropsin the proportions of non-poor and of moderately poor populations, and rise in the proportion of extreme poverty, 7) there are strong inequalities between states and between rural, urban and metropolitan settlements.

Institutional violence against women in Northwest Mexico

Scipedia content — Fri, 31 Mar 2017 14:19:21 +0200

This paper examines the existing regulatory framework for addressing violence against women in Mexico, both nationally and at the level of the four states that make up the geographic area where the research was conducted. We present some of the manifestations of violence: communal, in the workplace and feminicide. Emphasis is placed on how these are overlapped and harnessed by institutional violence, for which we take up the ideas of experts on the subject of violence. The results reveal how institutional practices re-victimize and violate their rights. In spite of the advances in legal matters, we do not yet have the sociocultural conditions to ensure that women can exercise their rights and lead a life free of violence.

Anthropological epistemology as knowledge of man: The rol of anthropology of technoscience

Scipedia content — Fri, 31 Mar 2017 14:19:17 +0200

The project of an epistemology of anthropological sustenance similar ideas akin to those who have expressed solidarity between epistemology and social theory. In the present case, the theory of knowledge is symbolized by an idea in the political epistemology, understood as political epistemology and a theory of human scale represented society, understood as anthropology. This article will visit the elements of this relationship conceptual and epistemological issues in some authors founders of anthropology and anthropological critics of the twentieth century epistemology, anthropology of technoscience and the proposal of a possible epistemology supported by the main dimensions matrix conceptual epistemological anthropology.

Fundamental postulates of Anthony Giddens’ reflexive modernity theory

Scipedia content — Fri, 31 Mar 2017 14:19:13 +0200

The purpose of this scholarly monograph is to introduce students of sociology and other social sciences to the theoretical postulates of Anthony Giddens about reflexivity and its relation to the radicalized modernity. For this purpose –attending space limitations–, I first layout the background that underlies his analysis of the transformations of contemporary society with reference to the theory of structuration. Secondly, I address the analysis of modernity made by the author, its reflexive condition and his thesis on the radicalization of the social process. Thirdly, I present some of the main themes that give continuity to his research program. In order to enrich this monograph I have included a selected bibliography of related issues and theoretical debates on the Giddens’ concepts and approaches.

The policy of the rights of the government of Mexico City

Scipedia content — Fri, 31 Mar 2017 14:19:09 +0200

This text deals with the analysis of the policy of the rights of the government of Mexico City which took place during the last three administrations. This government is considered as an institution identified with the political left of the country since it bases its government strategy on two core pillars: the democratization of the government and the design of new redistributive policies, mainly the social policy. With these referents, an analysis is made with the most important political guidelines, which characterized this policy since 1997. Thus a process of continuity is identified in the three administrations in which consecutively the political, social, civil and “collective” rights were introduced. It is analyzed in each case the specific policies which made valid these rights and it is emphasized the different limitations related to those policies. Finally, we highlight the difficulties and contradictions that these governments have faced due to the fact that it is a policy put into practice in the framework of an urban development deep inside neoliberal policies and the global economy rules.

A giant clear cell sarcoma on right scapular: A case report

Scipedia content — Fri, 31 Mar 2017 11:04:55 +0200

Clear-cell sarcoma is a rare and malignant soft tissue tumor most commonly located at the distal end of extremities and rarely at the trunk. Data on the clinical features of the tumor is limited, complicating the analysis of prognosis and establishment of treatment protocols. In our study, we present a case diagnosed with clear-cell sarcoma in his right scapula and treated with tumor resection and chemotherapy, combination of dacarbazine, pharmorubicin and cisplatin. The patient died due to multiple organ failure eight months after operation. Early diagnosis, attentive care, and extended surgical resection combined with adjuvant therapy is of essence in treatment of clear-cell sarcoma.

Effects of two different degrees of lateral-wedge insoles on unilateral lower extremity load-bearing line in patients with medial knee osteoarthritis

Scipedia content — Fri, 31 Mar 2017 11:04:50 +0200

The aim of this study is to assess the effect of 5 and 10° lateral-wedge insoles on unilateral lower extremity load carrying line in patients with medial knee osteoarthritis using the L.A.S.A.R. posture alignment system. Twenty subjects (10 females and 10 males, mean age 67.7 ± 5.4 years (range: 58–78) with bilateral medial knee osteoarthritis were included in the study. The laser line projected on the person by the L.A.S.A.R. posture alignment system showed joint load carrying line. The location of the joint load carrying line in static standing with one foot on the force plate was assessed with barefoot, and 5° and 10° lateral-wedge insoles. Displacement of the load carrying line was measured using a ruler placed tangentially to the patella at the level of joint line. The load carrying lines measured with 5° and 10° lateral-wedge insoles were significantly laterally located compared to that without wearing insole (p

A mini-invasive procedure for treating arthrofibrosis of the knee

Scipedia content — Fri, 31 Mar 2017 11:04:45 +0200

The aim of this study was to introduce the results of a novel mini-invasive operative technique comprising mini-incision release, “pie-crusting” lengthening of the quadriceps extensor, and arthroscopic lysis in severe arthrofibrotic knees. From 2010 to 2014, 17 patients (12 males and 5 females with a mean age of 44 years (range, 19–62 years)) with severely arthrofibrotic knees were treated with this operative technique. The mean follow-up duration was 23 months. The knee range of motion (ROM) was assessed with a goniometer. The functional outcomes were evaluated according to the Hospital for Special Surgery (HSS) score and Judets criteria. The ROM significantly improved from 29.7° (range, 7°–56°) preoperatively to 127° (range, 120°–136°) at the final follow-up in all patients (p 100°). The HSS score was improved from 70 points (range, 60–85 points) preoperatively to 91 points (range, 84–98 points) (p

Translation, cross-cultural adaptation, reliability and validity of the Turkish version of the Olerud-Molander Ankle Score (OMAS)

Scipedia content — Fri, 31 Mar 2017 11:04:41 +0200

The aim of this study was to translate and culturally adapt the Olerud-Molander Ankle Score (OMAS) into Turkish and to assess its reliability and validity. The Turkish version of the OMAS (OMAS-Tr) was developed after the translation and back-translation, which included the stages recommended by Beaton. The OMAS-Tr was administered to one hundred patients (49 females, 51 males, average age: 42.3 ± 17.7, range 16–81 years) with malleolar fractures. The OMAS-Tr was completed twice by each participant at 7- to 10-days intervals to assess test-retest reliability based on the interrater correlation coefficient, whereas Cronbachs alpha evaluated internal consistency. The external validity was evaluated with correlations between the Turkish version of the Foot and Ankle Ability Measure (FAAM) and the Turkish version of the SF-12 questionnaire. The distribution of floor and ceiling effects was also analyzed. The internal consistency (Cronbachs α = 0.84) and the test-retest reliability (ICC = 0.98) were excellent. The mean interval between the two tests was 8.6 ± 1.4 days. The mean and standard deviation of the first and second assessments of the OMAS-Tr were 74.1 ± 23.7 and 75.7 ± 23.9, respectively. There was a strong correlation between the OMAS-Tr and the FAAM subscales on activities of daily living and sports (r = 0.86, r = 0.83, p

Patellar tendon mechanical properties change with gender, body mass index and quadriceps femoris muscle strength

Scipedia content — Fri, 31 Mar 2017 11:04:37 +0200

The purpose of this study is to assess the effect and correlation of gender, body mass index (BMI) and quadriceps femoris (QF) muscle strength on patellar tendon (PT) thickness and stiffness in healthy sedentary individuals. This study was carried out with 67 (36 female, 31 male) healthy sedentary individuals between the ages of 18–44 (28.0 ± 7.5 years). The individuals included in the study were divided into two groups according to their gender and BMI (18.5

The effect of platelet-rich plasma on Achilles tendon healing in a rabbit model

Scipedia content — Fri, 31 Mar 2017 11:04:31 +0200

The aim of the present study was to evaluate the effects of PRP on Achilles tendon healing in rabbits during the inflammatory, proliferative, and remodeling phases by histological examination and quantitative assessments. Fifty mature male Japanese albino rabbits with severed Achilles tendons were divided into two equal groups and treated with platelet-rich plasma (PRP) or left untreated. Tendon tissue was harvested at 1, 2, 3, 4, and 6 weeks after treatment, and sections were stained with hematoxylin-eosin and monoclonal antibodies against CD31 and type I collagen. Collagen fibers proliferated more densely early after severance, and subsequent remodeling of the collagen fibers and approximation of normal tendinous tissue occurred earlier in the PRP group than in the control group. The fibroblast number was significantly higher in the PRP group than in the control group at 1 and 2 weeks. Similarly, the area ratio of CD31-positive cells was significantly higher in the PRP group than in the control group at 1 and 2 weeks. Positive staining for type I collagen was more intense in the PRP group than in the control group after 3 weeks, indicating tendon maturation. Administration of PRP shortened the inflammatory phase and promoted tendon healing during the proliferative phase.

Restore a 9 mm diameter osteochondral defect with gene enhanced tissue engineering followed mosaicplasty in a goat model

Scipedia content — Fri, 31 Mar 2017 11:04:25 +0200

The aim of this study was to evaluate the efficacy of gene enhanced tissue engineering followed mosaicplasty in a goat model. An acute cylindrical defect 9 mm in diameter was created in the weight bearing area of the medial femoral condyle in a goat model. Thirty-six medial femoral condyles were divided into 6 groups using different proportion of gene enhanced tissue engineering and mosaicplasty to restore the defects. The specimen received gross and histology observation, which was evaluated by the histological grading scale of O'Driscoll, Keeley and Salter. Transmission electron microscope observation was also performed. Two factors analysis of variance and Student-Newman-Kewls test were used to compare the specimen. The gross and histology observation revealed that each defects of six groups had different restoration. The scores of the reparative tissue of three groups with gene enhancement were significantly higher than those in other three groups without gene enhancement (p > 0.05). Gene enhanced tissue engineering followed mosaicplasty could restore a 9 mm diameter osteochondral defects in a goat model effectively. With the reduction of covering area of the graft, the advantages of the combined gene enhanced tissue engineering method can be better reflected.

Comparison of the chondroprotective effect of a novel hydrogel compound and traditional hyaluronate on rat cartilage in a papain-induced osteoarthritis model

Scipedia content — Fri, 31 Mar 2017 11:04:19 +0200

The aim of this experimental study is to evaluate the efficacy of a novel intraarticular drug in a papain induced osteoarthritis (OA) rat model and compare with the traditional hyaluronat (HA) visco supplementation. An early stage OA model was induced by the intra-articular injection of papain enzyme in the right knee joints of 44 Sprague-Dawley rats. Eleven rats (eleven right knees: papain group, 11 left knees: control group) were chosen randomly 28 days after the last injection and sacrificed for verifying OA. The remaining rats (n = 33) were randomly divided into 3 groups. Group 1 was injected 0, 2 mL of sterile saline solution (0, 9%), group 2 was injected 0, 2 mL HA and the group 3 was injected 0, 2 mL of HA-CSNAG (hyaluronat, chondritin sulfate, N-acetyl-d -glucosamine) combination in the right knees. Injections were performed on the 35th, the 42nd and the 49th days consecutively. Two weeks after the last injection, all groups were sacrificed to evaluate the severity of OA according to Mankin system. Early stage of OA was verified regarding total Mankin scores (p

Clinical and radiological results on the fixation of Neer type 2 distal clavicle fractures with a hook plate

Scipedia content — Fri, 31 Mar 2017 11:04:14 +0200

The aim of this study was to analyze the clinical and functional results of hook plate fixation in Neer type 2 distal clavicle fractures. We retrospectively analyzed 16 patients (11 males, 5 females) who were diagnosed with Neer type 2 distal clavicle fractures and treated with hook plate fixation between 2013 and 2014. Mean age was 38 (range: 27–61), and mean follow-up time was 14.3 (range: 12–18) months. Complications seen on radiographs were implant failure and subacromial osteolysis. The clinical results were evaluated with modified UCLA (University of California Los Angeles) scoring system. Bone union was achieved in all patients at the end of the first 4 months. Mean modified UCLA score was 32.75 (range 31–35). In 12 patients (68%), the implants had to be removed due to complications. After removal, the complaints regressed and shoulders' range of motion increased. Clinical and radiological results on the fixation of Neer type 2 distal clavicle fractures with a hook plate are good in terms of fracture union and function. The major disadvantage of the method was the requirement of early implant removal due to the hardware related complications and good results can be achieved only after plate removal. Optimizing the length of hook plate may lower the rate of complications. Level IV, Therapeutic study.

Comparison of multimodal intraoperative neurophysiological monitoring efficacy in early childhood and school aged children undergoing spinal surgery

Scipedia content — Fri, 31 Mar 2017 11:04:10 +0200

The aim of this study was to compare the performance of multimodal intraoperative neurophysiological monitoring (MIONM) in children below and over 6 years of age. 43 children, diagnosed with spinal pathologies were divided into two cohorts according to their age and enrolled in the study. Those under the age of 6 consisted group A, whereas those between the age of 6 and 11 consisted group B. All patients underwent spinal surgical procedures according to their diagnosis. A standard anesthesia protocol was given to both groups. Baseline somatosensory evoked potentials (SSEPs) and transcranial electrical motor evoked potentials (tcMEPs) were recorded and evaluated at specific time points for each patient. Except for the SSEPs in three cases, tcMEPs and SSEPs were recorded for all patients. There was no false-negative whereas 9 false positive recordings due to physiological conditions that all recovered intraoperatively. In 10 patients, MIOMN recorded more than %50 decrement, in which 8 had the kyphosis component. The tcMEPs fully recovered by the end of the operation except for the patient with post-tuberculosis kyphosis. There was no statistically significant difference in the mean threshold values with regard to transcranial stimulus intensity for the tcMEPs between the two groups. Compared to school aged children, both SSEPs, tcMEPs recordings are feasible and MIONM is effective for early childhood patients undergoing spinal surgery. Level III, Diagnostic Study.

Total hip arthroplasty in patients with ankylosing spondylitis: Midterm radiologic and functional results

Scipedia content — Fri, 31 Mar 2017 11:04:04 +0200

The aim of this study was to evaluate the clinical and radiological outcomes of total hip arthroplasty (THA) in patients with Ankylosing Spondylitis (AS). One hundred five hips of 61 AS patients (mean age: 41.3 ± 10.2 years) who underwent THA between 1997 and 2012 were included into the study. Dorrs classification of proximal femoral geometry, acetabular protrusio, bone ankylosis, acetabular protrusion, Brooker classification of heterotopic ossification (HO), Gruen and Charnley classifications of implant loosening were used in radiographic assessments. Patients were called back to return for an additional long-term follow-up for functional assessment. Cementless total hip arthroplasty was used in 83 hips (79%) and cemented TKA was used in 22 hips (21%). The overall rate of aseptic loosening was 7.6% at a mean follow-up of 5.4 years. Femoral loosening was statistically similar in cemented and cementless femoral components (14% vs. 8%, p = 0.089). Acetabular component loosening was statistically higher in patients with any degree of HO (p = 0.04). Regardless of the type of femoral implant (cemented or cementless), femoral component loosening was higher in Dorrs type C patients (p = 0.005). The average pre-operative HSS was 46.6 ± 16.3, and it improved to 80.7 ± 18.7 at last follow-up (p

Is pin configuration the only factor causing loss of reduction in the management of pediatric type III supracondylar fractures?

Scipedia content — Fri, 31 Mar 2017 11:03:58 +0200

Closed reduction with percutaneous pinning is the treatment of choice for displaced supracondylar humerus fractures in children. In addition to configuration of pin fixation, many factors have been attributed to loss of reduction (LOR). The aim of the present study was to review potential factors that contribute to loss of reduction in the closed management of type III pediatric supracondylar fractures. Treatment of 87 patients with type III supracondylar fractures was reviewed to determine factors associated with loss of reduction, 48 patients were treated with lateral pinning and 39 with crossed-pinning after closed reduction. Outcome parameters included radiographic maintenance of postoperative reduction. Lateral or crossed-pin configuration, pin spread at fracture site, pin-spread ratio (PSR), and direction of coronal displacement of the fracture were not associated with LOR. A significant difference (p = 0.01) was found between LOR rates of patients with medial wall communication and LOR. Medial wall communication is a contributing factor to LOR in the management of type III supracondylar fractures. Cross-pinning should be preferred when medial wall communication is present, to provide more stable fixation. Level IV, Therapeutic study.

Prevalence of flatfoot among school students and its relationship with BMI

Scipedia content — Fri, 31 Mar 2017 11:03:54 +0200

The aim of this study was to analyze the relation between the flat-footedness and obesity. A total of 1158 school children (653 male and 505 female) participated in this cross sectional descriptive study. According to their age, children were divided into three groups for each gender (6–10, 11–13, 14–18 years old). Diagnosis and severity of flatfoot was assessed in using the Dennis method. BMI of children were calculated as body weight divided by height squared (kg*m−2 ). Majority (83.9%) of respondents had normal feet. The prevalence of flatfoot was 16.1% with a decreasing trend with age. Boys had a higher frequency of flatfoot than girls, however the difference was not significant (p > 0.05). The prevalence of flatfoot was 17.5% in boys and 14.5% in girls. The percentage of overweight and obese children was 10.3%. A significant difference in the prevalence of flatfoot occurred between, under-weight (13.9%), normal-weight (16.1%), overweight (26.9%), and obese (30.8%), children. The increasing prevalence of childhood obesity is one of the most serious health challenges across the globe, and a positive correlation between increased BMI, and flatfoot is one of the potential complications.

Treatment of post-traumatic elbow deformities in children with the Ilizarov distraction osteogenesis technique

Scipedia content — Fri, 31 Mar 2017 11:03:49 +0200

The present study assessed functional and radiographic outcomes of distraction osteogenesis treatment of post-traumatic elbow deformities in children. Eight children were treated between 2008 and 2013 for post-traumatic elbow deformities using distraction osteogenesis. Mean age at time of operation was 10.9 years. Six patients had varus and 2 had valgus deformity. Magnitude of correction, fixator index, complications, carrying angle, and elbow range of motion were assessed. Functional results were graded according to protocol of Bellemore et al. Mean follow-up was 43 months. Mean preoperative varus deformity in 6 patients was 29.2° and valgus deformity in 2 patients was 28.5°. Preoperative flexion and extension of elbow were 123.8° and −10.6°, respectively. Mean carrying angle was 9° valgus at last follow-up. Mean flexion and extension were 134.4° and −6.0°, respectively. Change in carrying angle was statistically significant (p = 0.002). There were 2 grade 1 pin tract infections and 1 diaphyseal fracture of humerus. Functional outcome was rated excellent in 7 patients and good in 1 patient. Ilizarov distraction osteogenesis is a valuable alternative in treatment of elbow deformities in children. The surgical technique is simple and correction is adjustable. Gradual correction prevents possible neurovascular complications and minimally invasive surgery produces less scarring. Compliance of patient and family is key factor in the success of the outcome. Level IV, therapeutic study

Tibiotalocalcaneal arthrodesis by using proximal humeral locking plate

Scipedia content — Fri, 31 Mar 2017 11:03:45 +0200

The aim of this study was to evaluate the short-term clinical and radiological results of tibiotalocalcaneal arthrodesis (TTCA) with proximal humeral locking plate. Eight patients (7 female, 1 male, average age 53 years (range: 24–67)) who underwent TTCA with proximal humeral locking plate between 2009 and 2011, were retrospectively evaluated with AOFAS hindfoot scale and Maryland foot score system. The mean follow up was 32.6 months (range: 23–54). Complete fusion was achieved in 7 patients. Soft tissue infection was observed in 2 patients and reflex sympathetic dystrophy in 3 patients. All patients recovered with medical treatment. At the final follow-up, mean AOFAS Hindfoot score was 60 (range: 41–81) and Maryland Foot Score was 67.8 (range: 41–85). The satisfactory rates of AOFAS and MFS were found as 12.5% (1/8) and 50% (4/8), respectively. One patient had an incomplete union with 5 degrees of heel varus deformity and 5 degrees of equinus deformity was observed in another. There were no implant failure or deformation of the plate during the follow-up period. Our study suggests that proximal humeral plate may be an alternative for fixation in tibiotalocalcaneal fusion surgery.

To evaluate the clinical outcomes after total knee arthroplasty (TKA) using the Genesis II posterior stabilized prosthesis with a high-flex insert during the mid-term follow-up and to assess its effect on the Japanese lifestyle. Fifty-three consecutive patients (8 men and 45 women) underwent primary TKA. The mean follow-up time was 76 months (5–9 years). Clinical results were assessed with the Japanese Orthopedic Association osteoarthritis knee rating score (JOA knee score), range of motion, and lifestyle changes. The postoperative JOA knee score improved significantly compared to the preoperative JOA knee score. The mean preoperative flexion range improved from 112° to 123° postoperatively (p

An analysis of postoperative hemoglobin levels in patients with a fractured neck of femur

Scipedia content — Fri, 31 Mar 2017 11:03:29 +0200

The aim of this study was to analyze the changes in hemoglobin level and to determine a suitable timeline for post-operative hemoglobin monitoring in patients undergoing fixation of femoral neck fracture. Patients who underwent either dynamic hip screw (DHS) fixation (n = 74, mean age: 80 years) or hip hemiarthroplasty (n = 104, mean age: 84 years) for femoral neck fracture were included into the study. The hemoglobin level of the patients was monitored perioperatively. Analysis found a statistically and clinically significant mean drop in hemoglobin of 31.1 g/L over time from pre-operatively (D0) to day-5 post-operatively (p

Is there a correlation between the change in the interscrew angle of the eight-plate and the delta joint orientation angles?

Scipedia content — Fri, 31 Mar 2017 11:03:24 +0200

It is known that the screws of the eight-plate hemiepiphysiodesis construct diverge as growth occurs through the physis. Our objective was to investigate whether there is a correlation between the amount of change of the joint orientation angle (JOA) and that of the interscrew angle (ISA) of the eight-plate hemiepiphysiodesis construct before and after correction. After the institutional review board approval, medical charts and X-rays of all patients operated for either genu valgum or genu varum with eight-plate hemiepiphysiodesis were analyzed retrospectively. All consecutive patients at various ages with miscellaneous diagnoses were included. JOA and ISA were measured before and after correction. After review of the X-rays, statistical analyses were performed which included Pearson correlation coefficient and regression analyses. There were 53 segments of 30 patients included in the study. Eighteen were males, and 12 were females. Mean age at surgery was 9.1 (range 3–17). Mean follow-up time was 21.5 (range, 7–46) months. The diagnoses were diverse. A strong correlation was found between the delta JOA (d-JOA) and delta ISA (d-ISA) of the eight-plate hemiepiphysiodesis construct (r = 0.759 (0.615–0.854, 95%CI), p

Scipedia content — Fri, 31 Mar 2017 11:03:19 +0200

A fracture of the stem in a total hip arthroplasty (THA) is an uncommon complication. We report a case of femoral stem fracture in a 55-year-old male patient after a lightning strike. A revision was conducted using a Wagner osteotomy and a revision prosthesis. Dall-Milles cerclages were used to close the osteotomy. The postoperative evolution was satisfactory, with an immediate partial weight bearing, consolidation of the osteotomy after three months and return to daily activity without pain.

Incidence of second hip fractures and associated mortality in Taiwan: A nationwide population-based study of 95,484 patients during 2006–2010

Scipedia content — Fri, 31 Mar 2017 11:03:14 +0200

The aim of the study is was to determine the incidence and mortality of second hip fracture using a nationwide database. A nationwide epidemiological study was conducted using the Taiwan National Health Insurance Research Database from 2001 to 2011. Patients older than 50 years with hip fractures from 2006 to 2011 were included in the study. A total of 95, 484 hip fractures were identified, with subsequent second hip fracture occurred in 4102 of them. The incidence rate ratio of second hip fracture showed a 7.13 fold of risk of further hip fracture in 3 months, 5.21 fold in one year, and remained more than 2 fold in the end of 6th year when compared with the general population. The 6-year cumulative incidence of a second hip fracture was higher in female (8.0%) than in male (6.2%). A significantly higher 1-year mortality rate was seen after a second hip fracture (18.8%) compared to the first hip fracture (14.1%) (p

A novel intramedullary nail for use in the treatment of supramalleolar malunion and nonunion: A preliminary report of three cases

Scipedia content — Fri, 31 Mar 2017 11:03:07 +0200

The fractures around the supramalleolar region are difficult to manage and deformities may occur following insufficient or inadequate treatment attempts. The treatment of those deformities is even more challenging. The available options for surgical fixation have inherent problems considering the soft tissue problems, infection and compliance of the patients. In this study, we report the preliminary outcome of new IMN system in use of supramalleolar deformities. Three patients with supramalleolar deformities were recruited for this study. Two patients had periarticular distal tibia malunions and one patient had nonunion in same region. All patients were operated with using newly designed intramedullary nail system with a unique distal interlocking bolt screw. The outcome for each patient was followed-up and evaluated with using AOFAS score. The patients were followed up for 3 years, 3 months, and 6 months, respectively. The AOFAS scores were 36, 33, and 21 preoperatively, and 75, 68, and 75 postoperatively in Patients 1, 2 and 3, respectively. In our patient series, adequate fixation following correction of the deformity was seen. Although the number of the cases are limited this study provides encouraging results regarding the outcome of new IMN system in use of supramalleolar deformities.

Reverse Segond fracture and associated knee injuries: A case report and review of 13 published cases

Scipedia content — Fri, 31 Mar 2017 11:03:02 +0200

Reverse Segond fracture is originally described as an indirect radiographic clue for a specific injury complex of the knee joint that includes posterior cruciate ligament (PCL) rupture and medial meniscal tear. Herein, we describe a case with reverse Segond fracture associated with PCL avulsion fracture instead of PCL rupture. According to current literature review, reverse Segond fracture is not only associated with PCL and medial meniscal injuries, but also frequently associated with anterior cruciate ligament (ACL) and medial collateral ligament (MCL) injuries. Furthermore, medial meniscus and PCL may remain intact.

The aim of this study was to present characteristics and publication patterns of studies arise from orthopedic theses obtained from National Thesis Center, database in terms of publication years, study types, topics, level of evidence between 1974 and 2014. Firstly, National Thesis Center database was searched for orthopedics and Traumatology theses. The theses, which their summary or full text were available were included in the study. The topics, study types and quality of study designs were reviewed. Then theses were searched in the PubMed database. Journals of published theses were classified according to category, scope and impact factors of the year 2014. 1508 theses were included into the study. Clinical studies comprised 71, 7% of the theses, while 25, 6% of the theses were non-clinical experimental and 2, 7% of the theses were observational studies. Clinical studies were Level I in 8, 6% (n = 93) and Level II in 5, 8% of the theses (n = 63). A total of 224 theses (14, 9%) were published in the journals indexed in PubMed database from 1974 to 2012. Fifty-two (23, 2%) were published in SCI, 136 theses (60, 7%) were published in SCI-E journals and 36 theses (16%) were published in other Journals indexed in PubMed. The quantity and quality of published theses need to be improved and effective measures should be taken to promote quality of theses. Theses from universities and Training hospitals which did not allow open access, and, incomplete records of the National Thesis Center database were major limitations of this study.

Osteoid osteoma of the pisiform: A case report

Scipedia content — Fri, 31 Mar 2017 11:02:51 +0200

Osteoid osteoma is an uncommon benign bone-forming tumor of the musculoskeletal system but it is the most common primary bone tumor of the carpal region. However, only seven cases of its pisiform involvement have been described. We present a 19 year-old male patient with osteoid osteoma of the pisiform which initially could not be detected in any diagnostic study for long standing wrist pain. The patient was treated with excision and curettage. In 1 year of follow-up, the patient was asymptomatic without recurrence. In cases with long standing ulnar wrist pain, one should consider osteoid osteoma of the pisiform in differential diagnosis. If an OO is suspected, thin slice CT scan in initial evaluation would be valuable in preventing the patient from misdiagnosis or delay in diagnosis.

Long-term result of arthroplasty in the treatment of a case of ochronotic arthropathy

Scipedia content — Fri, 31 Mar 2017 11:02:46 +0200

Alkaptonuria is a rare metabolic disease caused by a partial or total deficiency of homogentisic acid oxidase, which results in excess homogentisic acid (HGA) levels. Homogentisic acid and its oxidation products can accumulate in hyaline cartilage, tendons, and ligaments. A 55-year-old male was admitted complaining of worsening chronic pain in his left knee. A radiographic evaluation showed tricompartmental end- stage osteoarthritis. A cemented total knee replacement was performed. At the 10-year follow-up, he had returned to full activity, had no knee pain, and was very satisfied with the outcome. No abnormality was observed in the femoral, tibial, or patellar components on radiography. We believe that total knee replacement is a good option in a patient with marked degenerative arthritis secondary to ochronotic arthritis.

Dual plating for fixation of humeral shaft fractures: A mechanical comparison of various combinations of plate lengths

Scipedia content — Fri, 31 Mar 2017 11:02:41 +0200

The role of plate configuration was found inconclusive on the biomechanical effects of the plate size and hole number for dual plate constructions in humeral shaft fractures. The purpose of this study was to test the biomechanical stability of various dual plate constructions. Twenty-four left humeri (4th Generation Composite Humerus, Sawbones, Malmö, Sweden) with comminuted midshaft humeral fracture were used. Four groups of plate constructs were tested: laterally fixed 8-hole locking plate and screws were combined with anteriorly locking plates containing 0, 4, 6, or 8 holes in groups I, II, III, and IV, respectively. The alterations in axial, bending, and torsional angles were recorded. There were no fixation failures during axial, bending, or torsional stiffness testing within the elastic behavior limits. Axial stiffness was highest in Group IV. Torsional stiffness, posterior-to-anterior bending stiffness, lateral-to-medial bending stiffness, and medial-to-lateral bending stiffness were lowest in Group I. The similar stiffness values for the 8-to-4 hole and 8-to-6 hole plate constructions indicate that the 8-to-4 hole construction is an option in young adults, while the stiffest 8-to-8 hole combination may be an option for osteoporotic patients.

Iatrogenic lateral meniscus anterior horn injury in different tibial tunnel placement techniques in ACL reconstruction surgery – A cadaveric study

Scipedia content — Fri, 31 Mar 2017 11:02:36 +0200

The aim of this study was to analyze the effect of tibial tunnel positioning in single bundle and double bundle ACL reconstructions on lateral meniscus anterior root. Twelve single knee cadavers were used, 6 for a single bundle ACL reconstruction, which were reamed gradually starting from 8 mm, 9 mm and ended with a 10 mm reamers, while the other 6 were prepared for a double bundle ACL reconstruction in which 7 mm reamer for the AM tunnel and 6 mm reamer for the PL tunnel were used. After drilling, changes of lengths and thicknesses of anterior horns of the lateral menisci were recorded. Before drilling, the groups were homogenous for the lateral menisci dimensions. After drilling, no statistically significant difference was noticed between the two groups. However, in single bundle group, 2 anterior horns width injury (1.44 mm and 2.13 mm) with the 9 mm reamer and 3 anterior horns width injury (2.51 mm, 3.55 mm and 4.28 mm) with the 10 mm reamer were recorded. However in double bundle group a single anterior horn width injury (2.82 mm) was recorded. Using a greater size reamer in single bundle reconstruction, causes a relatively higher risk of lateral meniscal anterior root injury. Lateral meniscus stability should be examined arthroscopically after reaming with large reamers.

Discrepancy between cervical disc prostheses and anatomical cervical dimensions

Scipedia content — Fri, 31 Mar 2017 11:02:32 +0200

The aim of this study was to assess appropriateness of the sizes of available cervical disc prostheses based on tomographic measurement of human cervical vertebrae. The anatomic dimensions of the C3–C7 segments were measured on 50 patients (age range 26–47 years) with computerized tomography scan and compared with the sizes of the popular cervical total disc prostheses (CTDP) at the market [Bryan (Medtronic), Prodisc-C (Synthes), Prestige LP (Medtronic), Discover (DePuy)]. The mediolateral and anteriorposterior diameters of the upper and lower endplates were measured with a digital measuring system. Overall, 43.7% of the largest implant footprints were smaller in the anterior-posterior diameter and 42.6% in the mediolateral diameter were smaller than cervical endplate measurements. Discrepancy of the level C5/C6 and C6/C7 was calculated as 56.2% at the anteroposterior diameter and 43.8% at the center of mediolateral diameter. Large disparity has been found between the sizes of devices and cervical anatomic data. Companies that produce CTDP should take care of the anatomical dimensions and generate different sizes of CTDP. Spine surgeon should be familiar with the size mismatch in CTDP that may affect the clinical and radiological outcome of the surgery.

Clinical outcomes of operative repair of complete rupture of the proximal interphalangeal joint collateral ligament: Comparison with non-operative treatment

Scipedia content — Fri, 31 Mar 2017 11:02:27 +0200

The purpose of this study was to compare the outcomes of non-operative treatment and operative repair of grade III injuries with complete rupture of the collateral ligament of the proximal interphalangeal (PIP) joint. Seventeen patients with grade III injuries with at least 6 months of follow-up were included. Seven patients underwent non-operative treatment and 10 patients underwent operative treatment. We evaluated the following clinical outcomes after treatment: 1) range of motion of the PIP and distal interphalangeal (DIP) joints, 2) joint stability, 3) pain score, and 4) amount of fusiform deformity of the PIP joint. There was no instability in the lateral stress test in either group. The ranges of motion of the PIP and DIP joints were not statistically different between the two groups at final follow-up. However, the ranges of motion recovered more quickly in the operative group than the non-operative group within the first 3 months after treatment. Patients in the operative group had less pain and better cosmetic appearance of the PIP joint. Our results suggest that operative repair of the PIP collateral ligament can provide good joint stability, rapid functional recovery, and minimize fusiform deformity of the PIP joint. Level III, Therapeutic study.

Evaluation of the orthopaedics and traumatology resident education in Turkey: A descriptive study

Scipedia content — Fri, 31 Mar 2017 11:02:16 +0200

The objective of this study is to describe the current situation regarding the training, working conditions, future plans, fields of interest and satisfaction of orthopaedics and traumatology residents in Turkey. A descriptive survey questionnaire consisting of 24 questions was designed to identify the problems and solution suggestions concerning training of orthopaedic residents. All orthopaedics and traumatology residents who took the 2013 Progress Testing for Speciality in Medicine (UEGS) held by Turkish Orthopaedics and Traumatology Education Council (TOTEK) were surveyed in the class at the end thereof as well as the young orthopaedic surgeons who were reached through the email groups of Turkish Society of Orthopaedics and Traumatology – Residents and Young Attendings Council (TOTBID-AGUH). A total of 725 residents and 132 young attendings were surveyed. The most outstanding answers are as follows: 62, 7% of the respondents replied to the question “Is there a training program/Is it being applied” as “yes/yes”. It was found out that 94, 3% of the respondents wanted to be involved in a rotation abroad. The “patient care” was the most common answer, with a ratio of 36, 9%, to the question “Whats the priority of the department you are studying in?”. Regarding work conditions, “many emergency on-calls” was found to be the most important parameter affecting life conditions (p

The new intra-articular calcaneal fracture classification system in term of sustentacular fragment configurations and incorporation of posterior calcaneal facet fractures with fracture components of the calcaneal body

Scipedia content — Fri, 31 Mar 2017 11:02:11 +0200

The aim of this study was to develop a new calcaneal fracture classification system which will consider sustentacular fragment configuration and relation of posterior calcaneal facet to calcaneal body. The new classification system used sustentacular fragment configuration and relation of posterior calcaneal facet fracture with fracture components of calcaneal body as key aspects of main types and subtypes. Between 2000 and 2014, 126 intraarticular calcaneal fractures were classified according to the new classification system by using computed tomography images. The new classification system was studied in term of reliability, correlation to choices of treatment, implant fixation and quality of fracture reduction. Types of sustentacular fragment comprised type A, B and C. Type A sustentacular fragment included sustentacular tali containing middle calcaneal facet. In Type B and C fractures sustentacular fragment included medial aspect and entire posterior calcaneal facet as a single unit, respectively. The fractures with type A, B and C sustentacular fragments were classified as main type A, B and C intra-articular calcaneal fractures. The main type A and B comprised 4 subtypes. Subtypes A1, A3, B1, and B3 associated with avulsion and bending fragments of calcaneal body. Subtype A2, B2, and B4 associated with burst calcaneal body. Subtype B4 was not found in the study. Main type C had no subtype and associated with burst calcaneal body. The data showed good reliability. The study showed that our new intra-articular calcaneal fracture classification system correlates to choices of treatment, implant fixation and quality of fracture reduction.

The primary factor for suture configuration at rotator cuff repair: Width of mattress or distance from tear edge

Scipedia content — Fri, 31 Mar 2017 11:02:06 +0200

The aims of this study was first to investigate whether the bite size or the bite distance from the tear edge is of primary importance in mattress suture configuration for rotator cuff repair. Secondly, whether the use of a 450 left side bent Arthro-Pierce™ (Smith & Nephew, Andover, USA) during suture passage can be more effective on the strength of the configuration compared to a straight Arthro-Pierce™. Twenty-eight bovine infraspinatus muscle tendons were randomized into four groups. Group 1, 5 mm wide ‘bite size’ × 15 mm length ‘distance from the tear edges mattress’, Group 2: 7.5 mm × 10 mm, Group 3: 15 mm × 5 mm ‘using straight Arthro-Pierce™’ and Group 4: 5 mm × 15 mm using left sided 450 bent Arthro-Pierce™. The repair specimens underwent cyclic loading prior to loading the failure testing. Cyclic elongation (mm), peak-to-peak displacement (mm), ultimate load (N), stiffness (N/mm) and failure mode were recorded for each specimen. The mean ultimate load in Group 1 was higher compared to group 3. The peak to peak displacement was higher in Group 4 compared to Group 1 (p

The effects of low-dose radiotherapy on fresh osteochondral allografts: An experimental study in rabbits

Scipedia content — Fri, 31 Mar 2017 11:01:57 +0200

The aim of this study was to investigate the effects of low-dose fractionated radiotherapy on cartilage degeneration after distal femoral fresh massive osteochondral allograft transplantation. Twenty-four New Zealand White rabbits were divided into three groups of 8 rabbits each. All rabbits underwent distal femoral medial condyle fresh massive osteochondral allograft transplantation from California rabbits. The group 1 underwent transplantation without any preliminary process. The group 2 underwent fractionated local radiotherapy of 100 cGy for five days starting on the transplantation day. The group 3 included the rabbits to which the grafts transplanted after radiating in vitro by a single dose radiation of 1500 cGy. The hosts were sacrificed twelve weeks later. Anteroposterior and lateral radiographs were taken. Synovial tissue, cartilaginous tissue, and subchondral bone were assessed histopathologically. Nonunion was present in three cases of group 2 and one of group 3 in which cartilage degeneration was more severe. Synovial hypertrophy and pannus formation were more obvious in non-radiated rabbits. Hypocellularity and necrosis of the subchondral bone were rare in group 2. More cartilage tissue impairment was present in group 3 compared to group 1. In osteochondral massive allograft transplantations, the immune reaction of the host could be precluded with radiotherapy, and the side-effects can be prevented by low-dose fractionated regimen. The total dose of fractionated radiotherapy for an immune suppression should be adjusted not to damage the cartilage tissue, but to avoid articular degeneration in the long term.

Minimally invasive plate osteosynthesis with PHILOS plate for proximal humerus fractures

Scipedia content — Fri, 31 Mar 2017 11:01:53 +0200

The aim of the present study was to evaluate results, including clinical and radiological outcomes and number of complications, following minimally invasive plate osteosynthesis (MIPO) of proximal humerus fractures, using the PHILOS® proximal humerus internal locking system (Synthes Holding AG, Solothurn, Switzerland). Retrospectively evaluated were 31 patients treated with MIPO (12 male, 19 female, average age: 58.4 years). Four patients had 2-part fractures, 14 patients had 3-part fractures, and 13 patients had 4-part fractures, according to Neer classification. Healing, complications, and head-shaft angle (HSA) were radiographically evaluated. Clinical outcomes were assessed at 1-year follow-up with Constant score. Average Constant scores for fractured and normal shoulders were 73.2 ± 10.9 and 84.8 ± 5.1, respectively. Varus progression, fracture type, and age had no significant effect on functional outcome. Average postoperative and follow-up HSAs were 130.80 ± 7.70 and 128.80 ± 10.00, respectively. Significant varus progression was observed during follow-up (p = 0.01). Varus progression was more prominent in patients with postoperative HSA

The comparative efficacy of kinesio taping and local injection therapy in patients with subacromial impingement syndrome

Scipedia content — Fri, 31 Mar 2017 11:01:48 +0200

The aim of this study was to compare the therapeutic effects of kinesio taping (KT) and local subacromial injection in patients with subacromial impingement, syndrome (SIS) with regard to pain, range of motion (ROM) and disability. Sixty-one patients (48 females and 13 males, mean age: 43.04 ± 6.31, years) with SIS were enrolled into the study. The patients were randomized into two treatment groups receiving either a single corticosteroid and local anesthetic (LA) injection, or kinesio taping performed three times by intervals of 3 day. Visual analog scale (VAS) was used to assess pain intensity, range of motion (ROM) degrees of, shoulder were recorded and Shoulder Pain and Disability Index (SPADI) was, performed to evaluate functional disability, before treatment, at the first and fourth, weeks after therapies. A exercise program was prescribed for both groups including pendulum, active range of motion (ROM) and strengthening exercises. Pain, functional outcome measures were determined to have improved significantly in both groups at the end of therapies at first and fourth weeks (p

Anterior tibial artery pseudoaneurysm due to interlocking bolt of tibial nail: A case report and review

Scipedia content — Fri, 31 Mar 2017 11:01:35 +0200

Vascular injuries associated with the tibial nailing have been reported in few case reports. We here report a unique case of anterior tibial artery (ATA) pseudoaneurysm caused by the second proximal coronal interlocking bolt. We found that the position of interlocking bolts on the nail brings them very close to the anatomical positions of arteries in leg. The reports of ATA injury by interlocking bolts highlight the need for reconsidering the nail design and screw hole positions.

Minimally invasive intramedullary nailing of clavicular fractures by a new titanium elastic nail

Scipedia content — Fri, 31 Mar 2017 11:01:30 +0200

The aim of this study was to evaluate clinical results of a new design titanium elastic nail (TEN) for displaced midshaft clavicular fractures. Between February 2012 and December 2013, a total 36 patients with displaced midshaft clavicular fractures were treated with intramedullary nailing stabilization with our new design TEN. Blood loss, mean times of operation, postoperative complications, hospital stays and time to bone union was recorded. The outcomes were evaluated with radiographic assessment, visual analog scale (VAS) score, the Constant-Murley, and the disabilities of the arm, shoulder, and hand (DASH) scores. The mean blood loss was 50.278 ± 10.753 ml, while the mean operation, hospital stay and bone union times were 46.417 ± 9.232 min, 10.056 ± 2.672 days and 11.583 ± 2.729 weeks, respectively. After removal of the TENs at a mean of 10.2 months (range, 8-13 months) after surgery, no re-fracture and nonunion was found in any patient. Two cases of shoulder back stabbing pain were spontaneously resolved later. The mean fracture healing time was 12 weeks. The VAS score and motion ranges of shoulder joint were significantly improved postoperatively (P

Soft-tissue osteoma of the thenar eminence

Scipedia content — Fri, 31 Mar 2017 11:01:25 +0200

The development of osteoma in soft tissues without a direct contact with the adjacent osseous and articular structures is a very rare event. The involvement of the hand is even rarer, with only two previous cases reported so far. A 25-year-old man presented with a painless solid mass in the thenar region of his right palm, which appeared almost 2 years ago and showed a progressive enlargement in the last months. Under regional anesthesia an excisional biopsy was performed and the histopathological evaluation of the lesion confirmed the diagnosis of soft tissue osteoma. The postoperative follow-up period was uneventful without any complication or recurrence. Following a brief period of hand physiotherapy the patient has returned to normal daily activities.

Cartilage repair strategies in the knee: A survey of Turkish surgeons

Scipedia content — Fri, 31 Mar 2017 11:01:20 +0200

The purpose of this study was to analyze the trends in cartilage repair strategies among Turkish orthopedic surgeons for isolated focal (osteo)chondral lesions of the knee joint. A web-based survey of 21 questions consisting of surgical indications, techniques and time to return to sports was developed to investigate the preferences of members of the TOTBID and the TUSYAD. A total of 147 surgeons answered the questionnaire.70% of the respondents were TUSYAD members. 82% of respondents had at least five years experience in arthroscopy. Half of the surgeons indicated that patient age of 50 was the upper limit for cartilage repair. Irrespective of activity level, microfracture (60–67%) was the most frequently used technique for lesions smaller 2.5 cm2 . In lesions larger than 4 cm2, MACI was the most commonly advocated procedure (67%). In patients with high activity levels, mosaicplasty was the first choice (69%) for lesions between 2.5 and 4 cm2 in size, followed by MACI (27%). Patient age, activity level, BMI and lesion size were important determinants for the choice of treatment of isolated chondral lesions in the knee. These results reflect the choices of experienced knee surgeons in the country. Although not widely performed in Turkey and has limited reimbursement by the health care system, the first choice for defects over 4 cm2 was second generation ACI. Third party payers & health reimbursement authorities should take into account that large defects require methods which are relatively expensive and need high technology. Cross-sectional survey, Level II.

Safety of modified Stoppa approach for Ganz periacetabular osteotomy: A preliminary cadaveric study

Scipedia content — Fri, 31 Mar 2017 11:01:13 +0200

The aim of this cadaveric study was to investigate the efficacy of the modified Stoppa approach in Ganz periacetabular osteotomy (PAO). The Ganz PAO was performed on 10 hemipelvises with normal hips, from 5 cadavers using the modified Stoppa approach through the Pfannenstiel incision. All of the osteotomies were performed under fluoroscopic control and direct visualizing the osteotomy site from the same incision. After the osteotomy, the acetabulum was medialized and redirected anterolaterally, and fixed with 2 screws. The neurovascular structures and the joints were examined by dissecting the soft tissues after fixation of the osteotomies. Outcome parameters were center-edge (CE) angle, the distances between the osteotomy and anterior superior iliac spine (ASIS), and between the osteotomy and the sciatic notch, neurovascular and joint penetrations. After the osteotomy, the mean CE angle was improved from 19.8° to 25.2°, mean distance between the osteotomy and ASIS was 3.1 cm, and the mean distance between the osteotomy and the sciatic notch was 10.2 mm. The neurovascular structures and the joints were examined by dissecting the soft tissues after fixation of the osteotomies. No damage to the joint, surrounding arteries, veins or nerves was detected in any of the cadavers. Bilateral dysplastic hips can be treated with a 10 cm, cosmetically more acceptable incision in the same session using this approach. Quadrilateral surface of the acetabulum can be directly seen using this approach and the osteotomy can be safely performed.

Evaluation of the informed consent procedure for total knee arthroplasty patients in Turkey

Scipedia content — Fri, 31 Mar 2017 11:01:08 +0200

The purpose of this research is to evaluate the ethical aspects of informed consent process of total knee arthroplasty (TKA) patients in Turkey. The study included 50 patients undergoing TKA in Gazi Mustafa Kemal State Hospital Orthopedics Clinic. A face to face survey was conducted to determine the ethical appropriateness of the main components of informed consent process such as, disclosure of material information about the disease and alternative treatment options, understanding the disclosed information, comprehending the written consent form and voluntariness in deciding. The survey revealed that all TKA patients signed informed consent form, 80% of the participants received material information about their disease, 62% were disclosed information about TKA operation, 56% read (in personal or with the assistance of a relative) the written informed consent form, 28% received information regarding possible complications of TKA and 85% were not given any information about the alternative treatments. Informed consent process in TKA patients have flourished compared to previous years, but still there are some aspects in need of improvement. Using short and understandable language, developing multi-media sources and involving patients to informed consent form development process would contribute to the process.

Effects of immobilization and whole-body vibration on rat serum Type I collagen turnover

Scipedia content — Fri, 31 Mar 2017 11:01:02 +0200

The aim of this study was to investigate the effects of short-term, high-magnitude whole-body vibration (WBV) on serum type I collagen turnover in immobilized rats. Thirty Wistar albino rats were randomly divided into the following 5 groups: immobilization (IS), immobilization + remobilization (IR), immobilization + WBV (IV), control (C), and WBV control (CV). Immobilization was achieved by casting from the crista iliaca anterior superior to the lower part of the foot for 2 weeks. The applied WBV protocol involved a frequency of 45 Hz and amplitude of 3 mm for 7 days starting a day after the end of the immobilization period. Serum type I collagen turnover markers were measured by using ELISA kits. Serum NH2-terminal propeptide of type I collagen (PINP) levels were significantly lower in the immobilization groups (p

Acro-osteolysis is a rare disease characterized by bone resorption involving the distal phalanges of the hand. We present a unique case of progressive acro-osteolysis of the distal phalanges and articular calcifications in a patient with scleroderma. The calcified deposit in a proximal interphalangeal joint was excised under local anesthesia. The medical treatment was arranged under the supervision of a rheumatologist.

Discriminative ability of calcaneal quantitative ultrasound compared with dual-energy X-ray absorptiometry in men with hip or distal forearm fractures

Scipedia content — Fri, 31 Mar 2017 11:00:53 +0200

The aim of this case–control study was to compare the discriminatory ability of bone mineral density (BMD) measurements and calcaneal quantitative ultrasound (QUS) parameters for fractures and to determine fracture thresholds for each variable in men with hip or distal forearm fractures. A total of 20 men with hip and 18 men with distal forearm fractures and 38 age-matched controls were included in this study. Dual-energy X-ray absorptiometry (DXA) BMD (spine and hip) and calcaneal QUS measurements were made. Area under the curves (AUCs) were calculated to assess fracture discriminatory power of DXA and QUS variables. Quantitative Ultrasound Index (QUI) T-score and Speed of Sound (SOS) were found to be the best parameters for the identification of hip and distal forearm fractures, respectively, with AUCs greater than those of DXA BMD and other QUS parameters. While a QUI T-score of ≤−1.18 could identify and rule out hip fracture cases with approximately 80% sensitivity and specificity, a SOS value of ≤1529.75 reached to almost 90% for ruling in and out distal forearm fractures. The discriminatory performance of calcaneal QUS variables between fractured and non-fractured men was as good as those of the DXA BMD and even better. Since men appear to sustain fractures at closer QUS variable levels than those of the DXA BMD regardless of the fracture type, it may be speculated that calcaneal QUS may be more helpful in predicting the risk of fractures when BMD alone does not demonstrate impaired bones.

Short Form Health Survey version-2.0 Turkish (SF-36v2) is an efficient outcome parameter in musculoskeletal research

Scipedia content — Fri, 31 Mar 2017 11:00:47 +0200

Although the Short Form Health Survey version-2.0 (SF-36v2) is widely used since 2000, the researchers and clinicians in Turkey have been still using the original version. However, the original version includes many deficiencies and the SF-36v2 was introduced aiming to correct these deficiencies. The purpose of this study is to indicate differences between SF-36 and SF-36v2 and the present cross cultural adaptation, reliability and validity of the SF-36v2. The SF-36v2 was cross culturally adapted to Turkish and the measurement properties of the Turkish version of the SF-36v2 were tested in 50 patients (19 males, mean ± SD age: 36.9 ± 14.6 years, range: 16–65 years, BMI, 24.1 ± 4.6) with a variety of musculoskeletal pathologies. Intraclass correlation coefficients (ICC) were used to estimate the test-retest reliability. Construct validity was analyzed with SF-36v2 and EuroQol Group (EQ-5D). The distribution of ceiling and floor effects was determined. During the cross-cultural adaptation process many changes were made. The Turkish SF-36v2 subscales showed excellent test-retest reliability which was ranged 0.80 to 0.95. The highest correlation was found between SF-36v2-PCS and SF-36v2-PF (r = 0.75), the lowest correlation was found between SF-36v2-PCS and SF-36v2-MH (r = 0.05). The correlations between EQ-5D and SF-36v2 subscales ranged from 0.10 (SF-36v2 –VT) to 0.46 (SF-36v2 –RE). We observed no ceiling and floor effects. The cultural adaptation of the SF-36v2 was successful. The SF-36v2 has sufficient reliability and validity to measure a variety of musculoskeletal pathologies for Turkish-speaking individuals.

An anatomic study of the lateral patellofemoral ligament

Scipedia content — Fri, 31 Mar 2017 11:00:41 +0200

The lateral patellofemoral ligament (LPFL) is part of the lateral retinaculum cut during arthroscopic or open release. We investigated its anatomic and morphometric characteristics. We identified the LPFL insertion point on the condyle in vertical and sagittal planes in 32 adult cadaveric knees. We measured its length and width at the insertion point. We located the midpoint of this point and measured from it to the distal and posterior condylar ends. We measured anterior-posterior and proximal-distal lateral condylar lengths. We evaluated the insertion point shape on the lateral femoral condyle. Degree of relationship between variables was assessed using Pearsons correlation coefficient. p

Peritoneum and omentum are natural reservoirs for chondrocytes of osteochondral autografts: A comparative animal study

Scipedia content — Fri, 31 Mar 2017 11:00:36 +0200

The purpose of this study was to investigate the effects of the omentum, peritoneum, paratenon and skeletal muscle on the proliferation of the cartilage tissue using rabbit model as an in vivo culture medium. 6 months old forty-five New Zealand rabbits were randomized into omentum, peritoneum, muscle, and Achilles paratenon groups. Standard sized osteochondral grafts were harvested from right knees and immediately placed into the specified tissues. Control group was fresh cartilage at the end of follow-up. After five months, samples were collected and evaluated macroscopically by measuring their dimensions (vertical = D1, horizontal = D2, and depth = D3) and volumes, and histologically by counting the chondrocyte number using camera lucida method. Macroscopically, increase in mean values for D1 and D2 dimensions of specimens from paratenon and omentum compared to pretransplant dimensions was statistically significant (p 0.05). Histologically, mean chondrocyte count was 14.0 ± 0.6 in fresh articular cartilage. Mean chondrocyte counts were 14.4 ± 0.9 in omentum group, 15.4 ± 1.0 in peritoneum group, 9.7 ± 1.3 in muscle group and 9.2 ± 0.4 in Achilles paratenon group respectively. However, mean chondrocyte counts were higher in samples of omentum and peritoneum group compared to fresh articular cartilage, increase was not statistically significant (p > 0.05). Transplantation of the cartilage grafts into mesothelium enhanced the chondrocyte counts and volumes compared with the pretransplant measurements. Mesothelium may have the potential to be used as an in vivo culture medium for osteochondral tissue growth.

The aim of this study was to compare midterm functional and radiographic results of minimal invasive plate osteosynthesis (MIPO) with intramedullary nailing (IMN) of simple intra-articular distal tibial fractures (AO-OTA type 43 C1-C2). Seventy-three simple intra-articular distal tibial fracture patients were evaluated retrospectively. All were treated between 2009 and 2014. The average age of the patients was 40.3 years. Thirty-seven patients were treated with IMN and 36 patients were treated with MIPO. Fibular plate osteosynthesis was applied in 5 cases (13.5%) in the IMN group and in 23 patients (63.9%) in the MIPO group. Functional results and complications of IMN and MIPO methods were assessed in 73 patients. The average union time was 16.4 ± 2.7 weeks in the IMN group and 15.2 ± 1.8 weeks in the MIPO group (p = 0.079). The average Olerud-Molander Ankle Score was 87.8 ± 8.1 in the IMN group and 81.5 ± 11.8 in the MIPO group (p = 0.013). Four patients in the IMN group experienced valgus malunion, while it was not observed in any patients in the MIPO group (p = 0.042). Recurvatum malunion was detected in 10 patients in the MIPO group and not seen in the IMN group (p = 0.001). Ankle dorsiflexion angle was 25.8 ± 4.5° in the IMN group and 33.3 ± 8.9° in the MIPO group (p = 0.000). Simple intra-articular distal tibial fractures are successfully treated with IMN and MIPO. Prevalence of valgus malunion was higher in the IMN group and recurvatum was more prevalent in the MIPO group. MIPO is the first preference according to the literature, however, successful results have been obtained with IMN in this fracture pattern. Level III, Therapeutic Study.

Treatment of osteonecrosis of the femoral head with free vascularized fibular grafting: Results of 7.6-year follow-up

Scipedia content — Fri, 31 Mar 2017 11:00:24 +0200

The aim of this study was to determine long term follow up of the patients who had femoral head osteonecrosis and had been treated with free vascularized fibular grafting. We retrospectively reviewed 28 hips of 21 patients who had undergone free vascularized fibular grafting for the treatment of osteonecrosis of femoral head. There were 16 male and 5 female patients. The mean age of the patients at the time of surgery was 30.7 years (between 15 and 53 years). The mean follow-up time was 7.6 years (between 5 years and 9.2 years). During follow-up, one patient died because of leukemia, and one patient was lost. The remaining 26 hips of 19 patients were evaluated. According to the Ficat classification, at the time of surgery, 17 hips were in grade 2 and 9 hips were in grade 3. The post-operative Harris hip scores in grade II disease were excellent in 12 patients, good in 3 patients, and fair in 1 patient. In grade III disease, 1 patient was excellent, 5 patients were good, and 1 patient was fair. There was a significant increase in HHS scores (61 ± 9.7 vs 84 ± 17.8, p

Biomechanical comparison of orthogonal versus parallel double plating systems in intraarticular distal humerus fractures

Scipedia content — Fri, 31 Mar 2017 11:00:18 +0200

In intraarticular distal humerus fractures, internal fixation with double plates is the gold standard treatment. However the optimal plate configuration is not clear in the literature. The aim of this study was to compare the biomechanical stability of the parallel and the orthogonal anatomical locking plating systems in intraarticular distal humerus fractures in artificial humerus models. Intraarticular distal humerus fracture (AO13-C2) with 5 mm metaphyseal defect was created in sixteen artificial humeral models. Models were fixed with either orthogonal or parallel plating systems with locking screws (Acumed elbow plating systems). Both systems were tested for their stiffness with loads in axial compression, varus, valgus, anterior and posterior bending. Then plastic deformation after cyclic loading in posterior bending and load to failure in posterior bending were tested. The failure mechanisms of all the samples were observed. Stiffness values in every direction were not significantly different among the orthogonal and the parallel plating groups. There was no statistical difference between the two groups in plastic deformation values (0.31 mm–0.29 mm) and load to failure tests in posterior bending (372.4 N–379.7 N). In the orthogonal plating system most of the failures occurred due to the proximal shaft fracture, whereas in the parallel plating system failure occurred due to the shift of the most distal screw in proximal fragment. Our study showed that both plating systems had similar biomechanical stabilities when anatomic plates with distal locking screws were used in intraarticular distal humerus fractures in artificial humerus models.

Elastofibroma dorsi: Clinical evaluation of 61 cases and review of the literature

Scipedia content — Fri, 31 Mar 2017 11:00:12 +0200

Elastofibroma dorsi (ED) is a rare, benign, soft tissue tumor typically located between inferior corner of scapula and posterior chest wall causing mass, scapular snapping, and pain. When classic symptoms and localization are present, it is diagnosed without biopsy and treated with marginal resection. This study retrospectively analyzed patients operated on for ED to evaluate presenting symptoms, tumor size, complications, and clinical results, and to suggest optimal treatments. This study included 51 patients who underwent surgery for ED in 2 different clinics between 2005 and 2015. Patient age, gender, profession, side affected, symptoms, average duration of symptoms, and tumor size were researched. Radiological examinations of patients were evaluated. Patients with lesions larger than 5 cm in size were operated on. Postoperative complications, recurrence, and functional results were evaluated using Constant score and compared to preoperative values. A total of 61 operated lesions of 51 patients clinically and radiologically diagnosed with ED were retrospectively evaluated. Average length of time patient experienced symptoms was 11.21 months. Lesions in 19 (37.2%) patients were bilateral, 10 of which were symptomatic and larger than 5 cm in size, meeting indication for surgery. Average lesion diameter was 8.7 cm. Average follow-up was 26.89 months. Average of preoperative Constant score of 67.28 subsequently increased to 92.88 (p

Clinical and pathological results of denosumab treatment for giant cell tumors of bone: Prospective study of 14 cases

Scipedia content — Fri, 31 Mar 2017 11:00:06 +0200

Giant cell tumor of bone (GCT) is a primary, osteolytic, benign tumor of the bone. Surgery is the commonly used treatment, however, recurrence remains a problem. Receptor activator of nuclear factor kappa B (RANKL) is responsible for the formation of osteoclastic cells. Discovery of RANKL and its human monoclonal antibody, denosumab, led to use of denosumab for treatment of GCT. The aim of this study was to evaluate clinical and pathological results of treatment of GCT with denosumab and to assess adverse effect profile and recurrence rate. Thirteen patients with 14 lesions were enrolled in the study. Mean age was 38.3 years. Patients were given subcutaneous injections of denosumab (120 mg) every 4 weeks (with additional doses on days 0, 8 and 15 in cycle 1 only) and were radiologically evaluated for tumor response. Pain and functional status were measured using Visual Analog Score (VAS) and Musculoskeletal Tumor Society Score (MSTS). Adverse effects were analyzed after each cycle. Participants were 5 men and 8 women. Mean follow-up was 17 months. One lesion was Campanacci grade I, 8 were grade II, and 5 were grade III. Eight lesions were recurrent, and remaining were primary lesions. After average of 9 cycles (range: 4–17 cycles), all tumors underwent radiological regression. Ten lesions were removed surgically. More than 90% of giant cells were found to have regressed in all pathological specimens. On last follow-up, average VAS was 1 and MSTS was 87%. Fatigue and joint and muscle pain after injections was reported by 46% of patients, and mild hypocalcaemia was seen in 1 patient. Denosumab has been shown to be a successful drug in treatment of GCT. Denosumab can be used as neoadjuvant for all recurrent lesions, grade II lesions with high surgical risk, grade III lesions, and metastatic cases of GCT. Level IV, Therapeutic study

Efficacy of preoperative administration of single high dose intravenous tranexamic acid in reducing blood loss in total knee arthroplasty: A prospective clinical study

Scipedia content — Fri, 31 Mar 2017 11:00:01 +0200

The aim of this study was to analyse the effectiveness of single dose of 20 mg/kg intravenous tranexamic acid (TXA), in reducing the blood loss in patients undergoing total knee arthroplasty (TKA). 70 patients (65.5 ± 8.1 years old) that have undergone TKA were divided in two groups. The 20 mg/kg IV TXA was given before the skin incision to one group (study group). On the control group, TKA was performed without TXA. The demographic data, body mass index, amount of bleeding and erythrocyte infusion during the operation, hemoglobin and hematocrit values (preoperative and 48th hour), the amount of drainage after the operation were compared between the groups. The total amount of bleeding in the study group was 634.03 ± 182.88 ml and 1166.42 ± 295.92 ml in the control group (p

Influence of patient training on persistence, compliance, and tolerability of different dosing frequency regimens of bisphosphonate therapy: An observational study in Turkish patients with postmenopausal osteoporosis

Scipedia content — Fri, 31 Mar 2017 10:59:55 +0200

In our study, we aimed to evaluate the influence of training on compliance and persistence with bisphosphonate treatment given on a weekly vs. monthly basis in postmenopausal osteoporosis patients. A total of 979 patients with postmenopausal osteoporosis (mean age: 63.2 ± 7.2 years) were included in this national, multicenter, prospective non-interventional observational cohort registry study. Patients were randomized into training (n = 492, 50.3%, mean age: 63.4 ± 7.2 years) and control (n = 487, 49.7%, mean age: 63.0 ± 7.1 years) groups. Patients in each intervention group were given weekly (44.9% and 44.6% for training and control subjects, respectively) or monthly (55.1% and 55.4%, respectively) bisphosphonate regimens. After the initial visit, patients were followed up at three-month intervals throughout 12 months of treatment for evaluation of persistence, compliance and adverse events. On average, 79.4% of the patients were persistent with the treatment with a mean of 350.4 days of duration during the 12-month follow-up period. The mean compliance in the compliant and fully compliant group remained at an average of 86.6%. No significant difference was detected between the training and control groups in terms of compliance and persistence. Significantly longer persistence (360.0 ± 89.0 vs. 345.0 ± 108.0 days, p = 0.035), higher percentage of persistent patients (83.4% vs. 74.2%, p = 0.012) and higher compliance rates (88.8% vs. 83.3%, p = 0.002) were noted in monthly regimen patients in comparison to those given weekly regimen. Our findings revealed remarkably high rates for persistence and compliance with bisphosphonate treatment in postmenopausal osteoporosis, with no impact of training on compliance and persistence rates. Longer persistence and better compliance rates were achieved with the monthly bisphosphonate regimen when compared to the weekly regimen.

The purpose of this study was to evaluate two versions of a programmed instruction training program designed to teach undergraduate college students a goal-directed systems approach to analyzing organizational systems (Malott & Garcia, 1987). The first version was a paper-based programmed instruction module that had previously been shown to be effective at training the basic knowledge of the concepts, however was ineffective at training the application of these concepts. A computer-based programmed instruction (CBPI) version was created to improve the application of these concepts, which was tested through a series of three open-ended posttests with increasingly explicit prompts for each successive test. The results of the study showed higher performance results for the CBPI versions across all three dependent variables. The results of a nonparametric global test showed a standardized effect size of .86 and a p-value of <.001.>

The present analysis is made about the National Survey Well-being (BIARE, for its acronym in Spanish) constructed by National Institute of Statistics and Geography (INEGI) for obtain subjective indicators well-being and happiness. The objective its to know the characteristics and differences between the people who report the lowest well-being and the highest well-being perception. The happiness indicator was selected from the questions: «How satisfied are you? » and «How many happy are you?», which have a ten-point responding scale, happy people was selected from point 10 (totally satisfied). People unhappy was selected from point 0 = «Nothing satisfied» and point 1 = «A little satisfied». Descriptive statistics and hypothesis test was performed for evaluate group differences using chi-square and U Mann-Whitney test. The conclusion its that the unhappy people, compared with the happy people, perceive unhappiness during long time, obtained achievements and recognition were lowest for unhappy people, more presence of diseases, few economic resources, few social contact with family and friends, lower capacity to give support to people and a lower perception of coping capacities.

The aim of the study was to evaluate the results of the treatment program for people who have problems with their drinking developed at Centros de Integración Juvenil, institute dedicated to treat, prevent and investigate addictions in Mexico. The evaluation was made by a cuanticualitative, transversal, comparative, ex post facto design. The first estimate was carried out with a purposive sample of 170 people (133 men and 37 women) who were participating in the treatment program. To do this, was design the test of Program Evaluation for Drinkers (CEPROBE ) to examine the emotional and health state, social integration, criminal behavior, assertiveness to confront the offer of alcohol, habit changes attributed to alcohol program and to assess service quality standards. For the second analysis, 24 Psychologists and 1 Physician (18 men and 7 women) were interviewed it means at an open questionnaire that explores the experience of the therapist in the course of the program. Overall, 47.3% of the patients decreased de use of alcohol, while 48.5% were able to quit it. With the Kruskal-Wallis test, the results suggest significant differences in the socio-emotional status mentioned and alcohol use of the subjects. Under the perception of patients and therapist, the program fulfilled adequately quality standards.

The main objective of this research was to generate a reliable and valid scale that assessed dwelling privacy in Mexico City’s population. A scale was developed specifically for this purpose. The scale included 20 items with five options for answers (Never, few times, sometimes, frequently and always). The scale was applied to a sample of 200 Mexico City’s inhabitants in order to obtain its psychometrical validation. The distribution of the participants was as follow: age between 14 to 75, 110 women and 90 men: diverse occupations and school levels. A proper analysis took place in order to learn about the items discriminative power, reliability and valid factorial structure. The final scale was conformed by 11 items organized by three factors as follow: 1) Information Access Control, 2) Person Access Control and 3) Intimacy it explains 68% of variance and has a reliability of Cronbach Alpha =0.89. Afterwards a Confirmatory Factor Analysis was conducted to verify if the structure obtained from the Principal Component Analysis was correct, and a good fit was achieved (df=39, x2= 48.07, p = .151, CFI= .987, RMSEA= .032).

Redefiniendo la felicidad: frecuencia versus intensidad

Scipedia content — Tue, 28 Mar 2017 15:51:39 +0200

Mexico is consistently portrayed as a happy country. Research endeavors, both national and international, show that Mexicos levels of happiness are favorable, although little has been done regarding specific measurement underpinnings. There is a constant debate on whether happiness should be measured in terms of frequency or intensity of positive affect over negative affect (Diener, Sandvik, & Pavot, 2009), although some consensus points toward frequencys superiority over intensity of emotions. Some authors insist that frequency can me more easily and accurately measured than intensity, allowing for cross-person metric comparisons. This research put to test the frequency-intensity debate by providing several conceptual frameworsk that accentuated one over the other, allowing people to decide how they defined their own happiness. Two independent samples (n1 = 158, n2 = 583) of Mexican men and women provided insights on whether happiness in Mexico is defined in terms of frequency or intensity. Once it was defined, happiness levels were compared between two groups showing that those who define happiness as “frequency” present higher levels of joy. This research supports the premise that happiness could be defined as the sum of frequent events, congruent with bottom-up approaches to happiness and wellbeing.

The sample was 109 patients and their partners, all of them included in the Cardiac Rehabilitation Program of the Ramon y Cajal Hospital in Madrid. Our results show that partner support has not a significant impact on patientś adjustment (received support [P = .46] and satisfaction with received support [P = .041]). However, partner support has a significant effect on adherence to health recommendations (food, physical exercise, smoking, etc), most of all in the 8 and 12 months’ follow-up (P

Dimensionality of the Brief Obsessive Beliefs Questionnaire in Mexico

Scipedia content — Tue, 28 Mar 2017 15:51:33 +0200

Recent models emphasized the importance in research of beliefs and its appraisal in the etiology and maintenance of OCD. The aim of the present study is the development and validation of a short form of the Obsessive Beliefs Questionnaire (OBQ, Belloch et al. 2003) in Mexican population. This topic was addressed through two different studies. Study 1: Exploratory factor analysis of the short version (200 non clinical subjects). The results show a different factor solution. Study 2: Testing for the equivalence of latent mean structures in multi-group analyses (200 and 202 non clinical subjects). A three-factor, 20 items, model emerged as the best factorial solution with similar psychometric properties to those of an English version (OBQ, Obsessive Beliefs Questionnaire, 2003). Given its consistency and repeatability, the Mexican version of the OBQ is a suitable instrument for the assessment of dysfunctional beliefs, although studies with clinical samples are needed.

Nostalgia for the couple

The objective of the present investigation was to describe the nostalgic experience for a previous partner, who is considered as someone important. We worked based on a non-probabilistic intentional sampling, composed by 200 young college students equally divided by sex, from 18 to 25 years old in the city of Toluca, México. We used a questionnaire validated by experts judges with a level of agreement higher than 85%, composed by six open questions. The applications were individual, in an approximately 20 minutes, in academic areas of the Universidad Autónoma del Estado de México. According to the obtained results, it was found that most of participants have had an important partner in their lifetime and what they liked the most about that partner was their personality, good treatment, physical appearance, favorable interaction and material benefits. Both sexes have frequent memories of that partner, been the men who report them most. Practically, all the participants agree that they miss the afective area. Men yearn the favorable interaction, while women miss more the share-time with the partner. The factors that motivates them to keep their actual relationship are the positive affection, comprehension, support and trust, personality, company, physical appearance and material benefits. Finally, most of participants declared that they do not consider as a posibility the get back together with their yearned partner, despite missing the animic status that they set up in the moment.

Causes That Take To Infidelity: An Analysis By Sex

Scipedia content — Tue, 28 Mar 2017 15:51:27 +0200

The aim was to detect the causes that lead more often to men and women to present the behavior of infidelity. To do this, it worked with a nonrandom sample of intentional type, consisting of 75 couples married and 75 couples in a dating relationship, residents of Toluca city, on condition of having committed an infidelity to their own partner. After obtaining the consent of each participant, applications were held individually at the Universidad Autónoma del Estado de México. The results show that infidelity had its origin in the lack. That is, in the absence of some satisfactions that they do not get with that couple. Also found that men committed an infidelity because they were feeling bored, uncomfortable, by a sexual need, for lack of variety and because they were confused in the relationship, compared with women who did it because they felt alone and misunderstood in the relationship. It was interesting to find that people who returned with the couple to whom they were infidel, they argued their decision because they found stability and love, that supposedly tried to get into the relationship of infidelity.

The purposes of this study were to determine the prevalence of psychosocial risk in major public officials who administer justice in Mexico City, and to identify the relationship between socio-demographic variables, occupational wear (burnout) and psychosomatic disorders. Information of 75 workers who administer justice was obtained in Mexico, DF (n = 75) by the Occupational Scale Wear of Uribe-Prado (2010). The results showed that burnout is the best variable to predict psychosomatic disorders in terms of psychosocial factors at work, analyzes of this study are discussed in terms of the importance of understanding the effects of psychosocial risk prevention, diagnosis and intervention from the response to chronic stress. Correlations, analysis of variance, regressions and a structural model to adjust the variables used in structural terms. Cronbach’s alpha for the evaluated variables was located between .63 and .83 reliability. The importance of secretaries, judges and magistrates to administer justice undertake their work in terms of occupational health is emphasized.

Explanatory Models of Condom Use in Coital Sex of Adolescents

The purpose of this study was to systematically investigate the attitudinal and interpersonal factors that influence condom use in coital sex between high school students and to develop structural models that show the interrelationships and the direct and indirect effects of these factors on frequency of condom use. Participants were 527 adolescents who reported having consensual sex at least once in life. For this matter a questionnaire measuring frequency of sex and condom use during sexual encounters was used, also 80 ordinal questions divided into five factors: 1) sexual assertiveness, 2) sexual submission, 3) low sexual risk perception, 4) infatuation and 5) acceptance of condom use. Using structural equations trajectories and frequency of condom use were drawn. Structural models for men and women show acceptable levels of fitness to the data as well as significant direct effects between all the variables, specifically direct effect of variables acceptance on condom use and sexual assertiveness on the frequency of preservative use. These results extend the possibilities of explanation and psychosocial intervention on sexual risk behavior among adolescents.

Worldviews, authoritarianism and dominance in different kinds of prejudice

Scipedia content — Tue, 28 Mar 2017 15:51:17 +0200

Worldviews are cognitive schemas available for individuals through the socialization process that generates stable social worldviews. The dangerous worldview (DW) and the competitive jungle worldview (CW) have been widely studied. Both are related to different social attitudes: DW relates to the right wing authoritarianism (RWA) and CW relates with social dominance orientation (SDO). Meanwhile, RWA and SDO are two social attitudes that predict different forms of prejudice. The main objective of this study was to adapt and validate the worldviews scale (WV) to the local context, and then to test two paths analysis with relationships between variables proposed in the background. Participants were 376 university students with an age range between 18 and 42 years (M = 24.29, SD = 3.3). Main results indicate adequate psychometric properties for the bi-dimensional worldviews model. Furthermore, it was also noted that the path analysis between DW-RWA-Prejudice was adequate, while the other including CW-SDO-Prejudice has metric problems.

Entendiendo la violencia en el Islam

Scipedia content — Tue, 28 Mar 2017 15:51:15 +0200

In the context of reduced violence world-wide, as documented by Pinker (2011), Islam is an exception, i.e., it is more violent than other cultures. Can contemporary cultural psychology explain aspects of this difference? It is hypothesized that violence is more frequent in cultures that are vertical collectivist than in cultures that are horizontal individualist. The paper reviews data that are generally consistent with this hypothesis. Furthermore, most Muslims are not violent, but perhaps 1 percent do engage in jihad. What personality aspects might explain this difference? It is argued that self-deception is very common among humans and the jihadists are especially susceptible to self-deception. Religion provides important benefits but it is also often related to violence. One way to reduce aspects of Islamic violence is for the West to ridicule Islam less. The paper also provides Islam with a more realistic model of its religion.

Auto-engaño: Una introducción

Scipedia content — Tue, 28 Mar 2017 15:51:12 +0200

Self-deception has been studied by philosophers and psychologists for some time. Frenkel-Brunswik (1939) published the first psychology paper. In Triandis (2009 p. ix) there are references to 24 papers by philosophers and psychologists that examined this concept. All humans have self-deceptions, some more frequently than others. That is, they see the world the way they would like to be rather than the way it is. As I thought about the concept over the years I believe that the most important point for understanding self-deception is to examine what percentage of the information that humans use when constructing (Taylor, 1998b) the way they see the world comes from inside their body or from outside their body. If most of it comes from inside their body there is a high probability that they have a self-deception. The information from inside the body consists of emotions (e.g., hopes), needs (e.g., hunger pangs), desires (e.g., imagined attractive objects), cognitive systems (e.g., prejudices, stereotypes, in-group preferences), memories (e.g., we are descendents of heroes), theories, ideologies, and elements of subjective culture acquired during socialization. The information from the outside the body is reality, and captures aspects of the ecology. Geography, climate, the actions of others, occupations, and events in the environment, are all relevant. For example, when a wild animal is attacking we focus on outside information. But when making judgments about philosophy, economics, religion, education, politics, terrorism, aesthetics and the like we often use inside information to shape our perceptions. The Buddha had the insight that we use information from both outside the body (reality, truth) and inside our body (emotions, ideology) when he said “Where self is, truth is not, where truth is, self is not.” (Spencer-Rogers, Williams, & Pang, 2010). In this paper I will start with some examples of self-deception. Then I will discuss some of the characteristics of self-deception—it is often linked to cognitive simplicity, megalomania, and if we have no self-deceptions we might be depressed, but if we have large self-deceptions we might be mentally ill. Then I will discuss how self-deception is implicated in many of the controversial issues of our times. I will end with some suggestions for further research linking culture and self-deception.

Do methods modulate the relation among delay, probability and social discounting?

Scipedia content — Tue, 28 Mar 2017 15:51:09 +0200

Delay, probability and social discounting refer to the decrease in the subjective value of a reward as a function of its delay of delivery, probability or social distance, respectively. One question in the area is whether the three types of discounting share the same process or whether they are held by different processes. This question has been investigated by looking at the correlations between the three types of discounting. Moreover, it has been suggested that the method used to obtain the indifference points could modulate the discounting rates. However, the search of a common process underlying the three types of discounting should not be influenced by the method used to obtain the indifference points. Therefore, the purpose of this study was to determine whether the method used to obtain the indifference points contributes to the correlation between the three types of discounting. Forty-four college students responded tasks of delay, probability and social discounting —which used a hypothetical monetary reward— with two different methods: Binary choice and adjusting amount. We found significant correlations between binary-choice and adjusting-amount methods for the three types of discounting. Albeit, a significantly higher delay discounting rate was found with the adjusting-amount method rather than with the binary-choice method, but there were no significant differences between the probability and social discounting rates obtained with both methods. In addition to the previous results, with the binary-choice method it was found that social discounting correlated with delay and probability discounting, but the last two did not correlate between them. In contrast, with the adjusting-amount method, it was only found a correlation between delay and probability discounting. The latter result suggests that the method used to obtain the indifference points contributes to the search of a common process between the three types of discounting. Actually a common decision-making process underlying the three types of discounting could depend on the context in which the choice is made.

Scipedia content — Tue, 28 Mar 2017 15:51:06 +0200

The aim of this study was to determine if processing speed, measured as visual reaction time (RT), of 10 month-olds obtained through an IPLP (Intermodal Preferential Looking Paradigm) in a word learning task, can be an indicator of communicative abilities such as productive vocabulary, during the second year of life. Participants were 13 infants of 9-12 months of age (X=10.15) at the beginning of the study, whose native language was Spanish and without visual or auditory problems reported by parents. The same group of infants was evaluated when they were between 24 and 30 months of age. Infants’ RTs were obtained at the age of 10 months in a word learning task, and related to communicative abilities measured with the Inventario de Habilidades Comunicativas MacArthur Versión II (CDI-II) when the infants were between 24 and 30 months of age (X=27.10). A linear regression analysis was performed using the RT from the experimental task as a predictor and the CDI-II vocabulary score as dependent variable. It was found that RT measured at 10 months of age can be used as a predictor of the vocabulary size in the same infants 18 months later. The results presented here imply that infants who take longer in processing a novel object associated with a novel word, are the ones who will have more words in their productive vocabulary during the second year of life, as reported by parents. The measures of processing speed in this study, demonstrates the length of time it takes a child to process non-familiar information in real time. The results obtained, support the study of processing speed at early ages in tasks that measure cognitive abilities other than word recognition. It suggests taking into account the analysis of individual differences, either processing speed or vocabulary, to better understand the relationship between these two variables in the first years of life. Furthermore, the results obtained in this paper highlight the importance of the study of RT in early ages and give information about the effects of slower or faster information processing over different linguistic abilities in infants.

Las Ciencias de Aprendizaje, Instrucción y Evaluación como Cimientos de la Instrucción Generativa del Modelo Morningside

Scipedia content — Tue, 28 Mar 2017 15:51:02 +0200

This paper focuses on a subset of the practices that have created the powerful learning technology developed and disseminated by Morningside Academy in Seattle, Washington, U.S.A. We briefly describe this technology, known as the Morningside Model of Generative Instruction, and tell how it builds on the selectionist approach of B. F. Skinner and the pragmatic approach of John Dewey. We also describe the critical role Precision Teaching plays at Morningside Academy and its dependence on findings from the science of learning and the science of instruction, including placement of learners, task analysis, content analysis, instructional protocols, and principles of instructional design. Last, we acknowledge the symbiotic relation between effective Direct Instruction programs that teach skills to accuracy levels and Precision Teaching, which takes these accurate repertoires and systematically turns them into high frequency performances that take on the character of fluent repertoires. Over time, using Precision Teaching across multiple and successive repertoires also creates more agile learners.

Working Memory and Fluid Intelligence. A Review of its Relations

Scipedia content — Tue, 28 Mar 2017 15:50:59 +0200

The aim of this paper is to contribute to the understanding of the relationship between working memory and fluid intelligence. A search was conducted in PubMed and Google Scholar database using a combination of the Spanish and English terms working memory (memoria de trabajo) and fluid intelligence (inteligencia fluida). The review indicates that attention control and the ability to retrieve information from long-term memory would be the processes through which working memory and fluid intelligence are related. However, there are conflicting results regarding the role of retention of information and information processing capacity in this relationship. We concluded by pointing out some methodological aspects that would enhance the understanding of the relationship between working memory and fluid intelligence.

Related Factors to Maternal Intake Control Practices in Preschoolers

Scipedia content — Tue, 28 Mar 2017 15:50:56 +0200

Parenting practices during the first years of life are crucial for the development of food preferences, self-regulation of intake and for establishing habits. The role of mothers is essential in the monitoring of their children´s feeding, and their practices may be influenced by several factors. In this study the relationship between mothers’ attitudes towards eating, the importance given to their own weight and that of their children, and intake control exerted over them was evaluated. 82 mothers of preschoolers participated. They were administered the Child Feeding Questionnaire, the Intake Control Exercised on the Children Questionnaire, and the Questionnaire of Emotions and Beliefs to Eating and Weight. Results indicate that concerns about the own weight and the children´s, the attitudes towards eating and the importance given to weight control, are related to the control exerted on children´s intake. This could generate thoughts and behaviors that could be constituted as risk or protective factors in the development of eating habits.

Construction of a Short Version Scale of Trait Depression in Adolescents

Scipedia content — Tue, 28 Mar 2017 15:50:53 +0200

Since adolescence is a particularly vulnerable stage to present depressed mood, and because there is a greater emphasis on depression as a state with the consequent lack of instruments to evaluate it as a feature (understood as the tendency to respond in a depressive way to daily situations), 407 young people with an average age of 20.14 years were evaluated. As the result, a reliable scale of five items was obtained (α = .711) useful to assess depression trait in adolescents. Its validity was confirmed by the convergence of the obtained scores with those resulting from the IDERE (Ramirez, Grau, Martin & Grau, 1989).

Administration of GABAA receptor antagonist bicuculline prevents the effects of administration of 5-HT1A receptor agonist on the discriminative properties of amphetamine

Scipedia content — Tue, 28 Mar 2017 15:50:50 +0200

In this research, the effects of systemic administration of the GABAA receptor antagonist bicuculline on the effects of 5-HT1A receptor agonist 8-OH-DPAT on the discriminative properties of the AMPH using the conditioned taste aversion procedure were evaluated. The results showed that neither 8-OH-DPAT nor bicuculline administration did not substitute for AMPH. However, the 8-OH-DPAT administration decreased the discriminative signal of AMPH and the bicuculline administration, prior to the 8-OH-DPAT administration plus a dose of AMPH prevented the effect of the 8-OH-DPAT on discriminative signal of AMPH. These data support the hypothesis that addiction-related behaviors of drugs such as AMPH involve several neurotransmitter systems such as DA, 5-HT and GABA.

Support, Supervision and Communication with Parents and its Relation to the Sexual Behavior of Young People in Conflict with the Law

Scipedia content — Tue, 28 Mar 2017 15:50:47 +0200

The present study was aimed to determine the profile of sexual risk behavior of adolescents in conflict with the law, and analyze the influence of parents on such behavior, considering the level of support and supervision of their children perceive them and the frequency with which they communicate on issues related to sexual health care. 320 men (M = 16.33 years) belonging to a Community Diagnostic of Mexico. The results showed that adolescents have sexual risk profile, they have started their sexual debut from the thirteen years they have multiple sexual partners were evaluated, and they report different sexual practices, a high percentage of teenagers reported having had sex under the influence of alcohol and drugs. Over 20% reported some sexual health problem. Regarding the role of the parents was found to promote different preventive behaviors, depending on whether the father or mother, for example, they delay their sexual debut, greater frequency of condom use, is less frequent sex under the effects of alcohol and drugs. The results are discussed in terms of the importance of involving parents in the assessment of sexual behavior and sexual health programs generate in this population.

Nicotine Assessment as an Aversive Stimulus

Scipedia content — Tue, 28 Mar 2017 15:50:43 +0200

Nicotine is the main ingredient of tobacco and it has been described as aversive, reinforce and procognitive. However there is not enough research about the overlapping of the dose-dependent effects as aversive stimulus and precognitive effects. For those reasons we evaluated the nicotine effects on the Conditioned Taste Aversion paradigm (CTA) to measure the dose-response curve of the aversive effects of nicotine and to compare such effects with the procognitive effects reported. 20 male Wistar rats in standard laboratory conditions were randomly assigned to 5 groups (0.0, 0.2, 0.4, 0.8 y 1.6 mg/kg i.p.). The obtained results showed a dose-dependent decrease with a maximum effect at 1.6 mg/kg dose, however we founded effects from the 0.8 mg/kg dose, such dose overlapped with procognitive doses reported. These results allow us to propose that some effects could be due the periferical aversive effects instead of the central procognitive effects.

Causes and Portrayal of Romantic Grief Stages

Scipedia content — Tue, 28 Mar 2017 15:50:36 +0200

Although is known that romantic experience gives pleasant sensations to an individual, to live a romantic lost brings pain feelings, desperation and anger because deception in front of reality which prior expectations in the ex partner weren’t possible to reach (Argyle&Furnham, 1983 ). During the romantic grief individual lives under the torment of hope and the possibility of living painful emotions constantly (Zaragoza Toscano, 2007 ). To evaluate the course of the grief process in those persons whose already finished their romantic relationship, we applied to 833 participants the Tridimensional Evaluation of Romantic Grief (Sánchez Aragón&Retana Franco, 2012). We identified four stages: Negotiation, Hostility, Hopelessness and Pseudo-Acceptance, which were supported by literature. We found some differences in the experience of the stages obtained due to the romantic grief reason. Specific findings show that infidelity provokes more hostility and hopelessness in comparison with other reasons as disagreements and lack of time.

Psychometric Evaluation of the Q-Sorts in Early Education Contexts

Scipedia content — Tue, 28 Mar 2017 15:50:33 +0200

As more women enter the workforce either as half or full time, it is now the norm in many societies for children to be placed in childcare before their first birthday. Because most of these children spend at least eight hours in childcare, we need to assess the quality of the service supplied by professional secondary caregivers (PSC). Maternal sensitivity is defined as mother’s ability to perceive and respond promptly and accurately to the child’s signals (Bowlby, 1969, Ainsworth, Blehar, Waters & Wall, 1978). The AQS (Waters, 1995) consists of 90 items describing attachment relevant infant behavior, the MBQS (Pederson & Moran, 1995) consists of 90 items describing maternal behavior. 34 child-PSC dyads were assessed in Mexican Social Security Child Care centers with the AQS and MBQS, to explore the factorial structure of sensitivity and secure base behaviors in Child Care facilities. The Child Care-adapted version of the AQS explains 52.99% of the variance (α=.69) and underlines the inconsistency of the relationship. The Professional Secondary Caregiver Q-Sort (PSCQS) explains the 45.35% of the variance (α=.91) with few and less specific factors than those previously reported in the MBSQ.

Use of the Depression Anxiety Stress Scales (DASS-21) as Screening Tests in Clinical Youngsters

Scipedia content — Tue, 28 Mar 2017 15:50:30 +0200

The short version of Depression, Anxiety and Stress Scales (DASS-21, Lovibond y Lovibond, 1995) has been shown to have appropriate psychometric properties among Chilean adolescents and undergraduates. The current study was aimed at determining the cut-off scores of the Depression, Anxiety and Stress Scales (DASS-21) for screening Chilean youngsters at risk of mental health problems and requiring mental health treatment. The sample comprised 393 non-patients youngsters aged 15-24 and 77 youngsters at early stage of psychotherapy. The presence of symptoms was used as gold standard for estimating the cut-off betWeen non-symptomatic youngsters and symptomatic patients. Receiving Operating Characteristic (ROC) analyses allowed examining accuracy of each scale and sensitivity and specificity analysis was performed for determining the cut-off points. The area under the receiver operating characteristics curve (AUC) was higher than 0.9 for each scale of the DASS-21. The optimal cut-off score for the Depression scale was 6 and above, which resulted in sensitivity=88, 46 and specificity=86, 77, and a cut-off of 5 and above was optimal for the anxiety scale, with a sensitivity of 87, 50 and specificity of 83, 38.The Stress Scale had sensitivity of 81, 48 and specificity of 71, 36 at the optimal cut-off score of 6 and above. These findings suggest that the DASS-21 performs adequately as a screening tool to identify Chilean young people at risk of mental health problems.

Family functioning as a predictor of alexithymia according to body mass index

Scipedia content — Tue, 28 Mar 2017 15:50:27 +0200

Alexithymia is a cognitive-affective disorder that causes a deficiency in the ability to identify, describe and express feelings (Sifneos, 1973), is related with familiar environment dysfunctional, as the involvement of the parents in the emotional needs of their children (Kind & Mallinckrodt, 2000). From this approach, the goal of the research was to determine if family functioning predicts alexithymia in persons with Body Mass Index (BMI) of normal weight, overweight and obesity. 428 collaborated voluntarily. Participated adults living in the Mexico City(M = 40 years, SD = 7.8) who responded to the Toronto Alexithymia Scale (Bagby, Parker & Taylor, 1994), Scale of Family Functioning (Garcia Mendez et al., 2006) and reported their height and weight to get their BMI. Analysis of stepwise linear regression were performed and the results suggest that in people with overweight and obesity, factors cohesion/rules and hostility/avoidance conflict are predictors of alexithymia. In normoweight, forecasters were command/problems in expressing feelings and cohesion/rules. These results show clearly that dysfunctional relationships facilitate the presence of behaviours related to alexithymia.

Construction and Validity of a Measure to assess Attitudes toward Successful Women

Scipedia content — Tue, 28 Mar 2017 15:50:24 +0200

Women are taking another position in the society, because they have accessed education, well-paid job, and politics, which generate changes which are related with the actual women role. Given the impact of these changes in interpersonal relationships, the objective of the present research was to construct a scale which measures the attitude to a successful woman in men and women. A sample was applied to 618 volunteer participants, 304 men and 314 women. After obtaining the internal consistent and the discrimination of reagents, a factorial analysis of the principal components with orthogonal rotation was made. The results grouped 71 reagents in four factors: leader, affective-altruistic, self-sufficient and competent.

Personality Attributes as Determinants of Attitudes towards Successful Women

Scipedia content — Tue, 28 Mar 2017 15:50:21 +0200

This paper has the aim of knowing which of the personality attributes linked to instrumentality (set of characteristics linked to competivity, responsibility, and achievement orientation) and expressivity (set of characteristics linked to the expression of affect, and caring for others) is the best predictor for attitudes towards successful women in both men and women. A sample of 908 voluntaries (454 men, 454 women), all residents of Mexico City, was used for this study. Results show the impact of positive instrumentality and positive expressivity (androgyny) is important for men and women to determine their positive attitude towards a successful woman.

Implementación del Juego del Buen Comportamiento en Aulas para Niños con Conducta Delictiva

Scipedia content — Tue, 28 Mar 2017 15:50:18 +0200

The good behavior game (GBG) is an interdependent group contingency procedure designed to reduce disruptive behavior in classroom settings. In the GBG, a class is divided into groups, simple rules are made, and contingencies are placed on the students’ rule-following behavior. This procedure has been proven effective across various student ages, and its simplicity and long-term effects have contributed to its popularity in school settings. Although it has been systematically evaluated across a wide range of student ages, research on the GBG is lacking in the area of population- and setting-specific assessments. In this evaluation, the GBG was implemented in three classrooms (student ages 7-12) at a school for children with severe problem behavior, in particular, these students had already displayed behavior that might be described as “delinquent” or “predelinquent.” Disruptive behavior substantially decreased across all three classrooms as a result of the intervention. This application extends the current literature by systematically replicating the results of the GBG with a different population. Implementation of the GBG, population-specific obstacles, results, and future directions are discussed.

Resilience in Surviving Pediatric Burn Patients

Scipedia content — Tue, 28 Mar 2017 15:50:15 +0200

Burn injuries are considered one of the most traumatic injuries a child or adolescent may experience and their consequences go beyond the physical problems, therefore the knowledge of positive adjustment after a burn is important. The aims of this study were to identify the levels of resilience in a group of pediatric burn survivors and to evaluate the differences by sex. This was a cross-sectional study in which 57 children and adolescents burn survivors, who attended to the Plastic Surgery Service of the UANL University Hospital, were evaluated. The results showed that children and adolescents of this study reported a high level of resilience, so it can be concluded that experiencing a traumatic or devastating event does not necessarily leads to negative consequences in psychological or behavioral functioning.

Happiness Scale in the Couple: Development and Validation

Scipedia content — Tue, 28 Mar 2017 15:50:12 +0200

Human happiness is complex, and in interpersonal terms, particularly in a relationship, there are many elements involved (Argyle, 1987 ). But there is no scale to measure happiness in the couple, therefore, the objective was to develop and validate a scale of happiness in the couple, culturally appropriated and reliable. The research was conducted in two phases. In the first phase, a scale for happiness in the couple was developed and reliability and validity were obtained, in the second phase, we performed a second-order factor analysis. The results showed a valid and reliable scale that measures the evaluation of happiness in the couple as well as the elements needed for a couple to be happy.

Investigación sobre cultura en psicología: Actualidad y visión hacia el futuro

Scipedia content — Tue, 28 Mar 2017 15:50:10 +0200

Cross-cultural psychology, in both its culture-comparative and its cultural traditions, has been a highly successful enterprise, it has been instrumental in establishing context variation as an essential factor in the study of behavior and has led to a large volume of publications with culture as a key term. At the same time, the question arises whether the further accumulation of findings of often small differences between groups will continue to be a worthwhile pursuit, or whether it is time for a reorientation. Here two widespread assumptions of research on behavior and culture are discussed that are likely to be unsustainable: (i) a focus on cross-cultural differences at the cost of cultural invariance, (ii) the presumed psychological coherence of cultures, especially national cultures, reflected in major dimensions of differences in psychological functioning. It is argued that also emerging methods in cultural neuropsychology continue to place too much emphasis on cross-cultural differences and cultural coherence. With a view to reorientation two ideas are explored: (i) culture-comparative research needs an explicit focus on what humans as a species have in common (psychological invariance) and (ii) explanatory frameworks should have a better theoretical foundation. Research traditions in biology are mentioned that can provide a source of inspiration to researchers in cross-cultural psychology. One such tradition is classical ethology as outlined by Tinbergen (1963) who proposed that in the analysis of behavior patterns researchers should be asking multiple questions about the immediate context (cause), function, ontogenetic development and phylogenetic history.

Parenting Styles: Their Relationship in Negotiation and Conflict Between Parents and Adolescents

Scipedia content — Tue, 28 Mar 2017 15:50:07 +0200

The aim of this study was to analyze the influence of parental styles in negotiation and conflict between parents and adolescents, from the perspective of each one. So the study was divided into two phases. The purpose of the first phase was to analyze the interrelationships between parenting styles that adolescents perceive both parents and styles of negotiation which the teenager used. The goal of the second phase was to analyze the influences that have parental styles in the conflict padres-adolescents, from the perspective of fathers and mothers. The results obtained in this study allow deducing that the parental style influences the way in which teenagers particípate in the negotiations, as well as in the intensity and frequency of the conflict perceived by parents. We conclude that when the parenting style of both parents is perceived warm teen uses a negotiation based on collaboration-equity, while parents characterized as warm, perceive a decrease in the intensity and frequency of conflict with their children.
