A new magnetic internal distractor: cadaveric study of changes in trapeziometacarpal joint forces.

Distraction is a new treatment for trapeziometacarpal joint osteoarthritis. The purpose of this study was to test the efficiency of magnetic distraction using a new internal distractor in cadavers. The distractor consists of two magnets embedded inside titanium capsules that are implanted on either side of the trapeziometacarpal joint with the same poles facing each other, so that the force between the magnets distracts the joint.

The Epidemiology of Gender Dysphoria in Iran: The First Nationwide Study.

Gender dysphoria (GD) is defined as a persistent and distressful incongruence between one's gender identity and one's at-birth-assigned sex. Sex reassignment has been religiously accepted for transgender individuals in postrevolutionary Iran since 1987; however, very little is known about how many individuals seek and receive such treatment annually. This study provides the first nationwide effort to assess the prevalence of GD in Iran as a function of diagnosis.

Biomechanical evaluation of intraosseous distal radioulnar joint prosthesis: A prosthesis designed based on Sauvé-Kapandji procedure.

Introduction: To avoid the DRUJ surgical procedures disadvantages, a new intraosseous distal radioulnar prosthesis designed on Sauvé-Kapandji procedure has been introduced. Stability of the prosthesis and biomechanics are to be evaluated in this article.

Materials And Methods: On a cadaveric study, during placement of the prosthesis, biometry of the bones, prosthesis stability (in axial and lateral tractions, wrist pronation and supination, and squeeze test), wrist range of motion before and after implantation, and radiographic evaluation were done on 16 cadavers.

Comparison of the effect of standardized patient-based training with team-based learning on the knowledge of midwifery students in providing services to victims of rape.

Background: Rape is a widespread and important issue in the field of public health, and its victims require comprehensive and gender-sensitive health services. Healthcare providers, especially midwives, play an important role in the diagnosis and treatment of rape, and improving their knowledge has been an essential factor in enhancing the quality of service provided.

Objective: The objective of the study is to compare the impact of standardized patient-based training and team-based learning on midwifery students' knowledge for providing services to rape victims.

Evaluation of Anatomic Variations of Fibula Free Flap in Human Fresh Cadavers.

Background: Reconstruction of the head and neck defects is still one of the most challenging surgeries for the surgeons. This study investigated on anatomic variations of fibula free flap in human fresh cadavers.

Methods: Twenty fibula free flaps harvested from 10 fresh human corpses were enrolled.
