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.

Simultaneous measurement of formic acid, methanol and ethanol in vitreous and blood samples of postmortem by headspace GC-FID.

Background: Formic acid (formate) is the main reason for toxicity and death through methanol poisoning. The simultaneous determination of methanol, ethanol, and formate in the body can help to discover the cause of death and is useful in the diagnosis of acute methanol poisoning. The measurement of formate is not yet available in Iran.

Three years evaluation of retained foreign bodies after surgery in Iran.

Background: Medical errors such as retained foreign bodies (RFB) during surgery are not well studied. To define risk factors associated with this type of error, we performed retrospective study.

Methods: We reviewed medical records for unintentional foreign object remaining in the body during surgery such as gender, age, surgery ward, and incident reports referred to several forensic medicine administrations as well as adverse effects of retained foreign bodies and methods for detection of them over a 3-years period from January 2008 through May 2011.

Accessory Spleen in the Splenic Hilum: a Cadaveric Study with Clinical Significance.

Aim: An accessory spleen is an additional tissue of the spleen that may be found near the spleen. It is a congenital anomaly of the spleen that its incidence has been reported 10-30% of the population. Hence, the objective of this study was evaluation the incidence of accessory spleen in Iranian cadavers.

Study of the normal heart size in Northwest part of Iranian population: a cadaveric study.

The heart is in a muscular organ in the middle mediastinum. According to our knowledge, there is no standard data about the anthropologic parameters of normal Iranian hearts. Hence, the aim of the present study was to investigate the normal heart size in Iranian cadavers.

Chemical Components of Noncommercial Alcohol Beverage Samples: A Study With the Viewpoint of Toxic Components in Mashhad, Iran.

Background: Iran has one of the lowest alcoholic beverage use rates in comparison with other countries, because it is legally forbidden and because of religious beliefs. Even so, unrecorded and noncommercial alcohol remains a considerable concern, which needs special attention.

Objectives: In the current research, we have studied the general composition of noncommercial alcohol samples to identify potentially toxic components in the context of the city of Mashhad in IR Iran.

Nontraumatic Retroperitoneal Hematoma After Warfarin Administration: Fatal Case Report and Review of the Literature.

Spontaneous retroperitoneal hematoma after warfarin therapy is an extremely rare event. Here, we report a 25-year-old man who was brought in to the emergency service with confusion. On arrival, the patient had hypotension, tachycardia, tachypnea, low-grade fever, and Glasgow Coma Scale score of 12.

Sudden death due to anaphylactic shock in a patient with an intact hepatic hydatid cyst.

Hydatid disease of the liver is a parasitic infection primarily caused by the larvae of Echinococcus granulosus. Hydatid cysts may remain clinically silent for many years and are often an incidental finding on ultrasonography performed for unrelated reasons. Sudden death due to unrecognized hydatid cysts can occur, and rare case reports of this kind are present in the literature.

Missed opportunities for diagnosis of post-traumatic thrombosis: a case series and literature review.

Thrombosis is caused by abnormalities in the composition of the blood, the quality of the vessel wall, and the nature of the blood flow. Herein, we present four cases of fatal thrombus formation after a trauma, which were missed at clinical diagnosis as the symptoms were misinterpreted. We stress that a blunt trauma can be fatal because of its direct and indirect kinetic energy effects at the subacute phase.

Lymph node co-infection of mycobacterium avium complex and cytomegalovirus in an acquired immunodeficiency syndrome patient.

Acquired immunodeficiency syndrome patients are known to have an increased tendency for developing opportunistic infections. However, there are no reports of simultaneous lymph node involvement of cytomegalovirus and Mycobacterium avium complex in a human immunodeficiency virus-positive patient. We report a 31-year-old man who presented with acute abdominal pain and tenderness and weight loss.
