Clinical and Sociodemographic Features of Alopecia Areata in Five Colombian Cities: An Analysis of the RENAAC Registry.

Background: Alopecia areata (AA) is an autoimmune disease characterized by non-scaring hair loss and preservation of hair follicles. The information available on disease course, and clinical features of AA is scarce worldwide, and almost nonexistent in Colombia.

Objective: To determine the clinical and sociodemographic characteristics of patients diagnosed with AA who presented to a dermatology consultation in five Colombian cities.

Sleep deprivation among surgical residents: Does it affect performance while practising a laparoscopic intestinal anastomosis?

Introduction: To assess the impact of fatigue due to incorrect night rest in the performance of a laparoscopic manual anastomosis.

Methods: A prospective study evaluating the results from the realization of a manual endotrainer entero-enteral anastomosis performed by residents in terms of fatigue caused by inadequate nightly rest. Two groups were established; the FATIGUE group (F): anastomosis performed by residents coming off shift who slept less than seven hours and the REST group(R), being those who slept at home for more than 7 h.

Analysis of learning styles in a laparoscopic technical skills course. Implications for surgical training.

Introduction: Learning surgical techniques is a dynamic process. In the 1980s David Kolb described developed a learning model that enabled teaching styles to adapt for better learner outcomes. The aim of this study was to identify the Kolb learning styles of the participants in a laparoscopic technical skills course and to check see if there was any relationship with performance.

Second GHEP-ISFG exercise for DVI: "DNA-led" victims' identification in a simulated air crash.

The Spanish and Portuguese-Speaking Working Group of the International Society for Forensic Genetics (GHEP-ISFG) has organized a second collaborative exercise on a simulated case of Disaster Victim Identification (DVI), with the participation of eighteen laboratories. The exercise focused on the analysis of a simulated plane crash case of medium-size resulting in 66 victims with varying degrees of fragmentation of the bodies (with commingled remains). As an additional difficulty, this second exercise included 21 related victims belonging to 6 families among the 66 missings to be identified.
