Factors affecting bowel gangrene development in patients with sigmoid volvulus.
Sigmoid gangrene develops in 6.1% to 93.4% of sigmoid volvulus (SV) cases, and increases the mortality rate from 0% to 40% without bowel gangrene to 3.7% to 80%. This study aimed to investigate factors that induce bowel gangrene development in SV patients. ⋯ An inverse correlation between pregnancy and sigmoid gangrene was observed. On the other hand, a positive correlation was noted between bowel gangrene and comorbid diseases, shock, prolonged duration of symptoms, overrotation, and associated ileosigmoid knotting.

Historical ArticleMirrors and reflections: the evolution of indirect laryngoscopy.
Indirect laryngoscopy traditionally entails the use of both a head mirror and laryngeal mirror. It is the first and most basic successful technique for viewing the larynx, and arguably remains the most commonly used diagnostic method for laryngoscopy today. This article reviews its evolution, from Albucasis' early applications of reflection and succeeding experiments with refraction, to Hoffman's design of the head mirror and subsequent modifications with illumination, culminating in Manuel Garcia's description of mirror laryngoscopy in 1854 and its refinement by Türck and Czermak.

Harassment has a negative effects on residents' health and on their ability to function. No previous study has documented the prevalence of harassment and discrimination among residents in Saudi Arabia. We aimed in this study to assess the prevalence of harassment and discrimination among residents at a tertiary care academic hospitals in Saudi Arabia. ⋯ Harassment and discrimination of Saudi residents is common with more than three-quarters reporting having had such an experience. Identification of the risk factors is a necessary first step in clarifying this issue and could be used when planning strategies for prevention.

Importance of viral pathogens in children with acute gastroenteritis in the south of Iran.
Different types of viruses are the leading cause of acute diarrhea among infants and young children worldwide. Epidemiological surveillance of viral agents is critical for the develop.ment of effective preventive measures, including vaccines. This study aimed to determine the prevalence of the four major enteropathogenic viruses-rotavirus, norovirus, adenovirus and astrovirus-in children over 7 years of age. ⋯ Since nearly half of gastroenteritis cases (44.3%) were due to viral agents, testing for the viral antigens may guide the clinical approach to those patients with acute diarrhea particularly in the case of children less than 2 years old, and during cold seasons.
