[Severe poisoning by plants used for traditional medicine in Mayotte].

The authors describe three cases of severe accidental poisoning by plants used as part of a traditional treatment in Mayotte. The established, or suspected, toxicity of Thevetia peruviana (Yellow oleander), Cinchona pubescens (Red quinine-tree), Melia azaderach (Persian lilac, also called china berry) and Azadirachta indica (Neem), is discussed. The clinical presentation is cardiac (atrioventricular block) and well known for Thevetia and Cinchona intoxications.

Small dead space heat and moisture exchangers do not impede gas exchange during noninvasive ventilation: a comparison with a heated humidifier.

Objective: Adverse respiratory and gasometrical effects have been described in patients with acute respiratory failure (ARF) undergoing noninvasive ventilation (NIV) with standard heat and moisture exchangers (HME). We decided to evaluate respiratory parameters and arterial blood gases (ABG) of patients during NIV with small dead space HME compared with heated humidifier (HH).

Design: Prospective randomized crossover study.

[Drug-induced hypersensitivity syndrome in internal medicine: diagnostic and therapeutic traps. Eight observations].

Purpose: Drug-induced hypersensitivity syndrome (DIHS) is an acute and severe drug reaction. Manifestations include severe skin lesions, fever, nodal enlargement, blood eosinophilia and multisystemic involvement. The severe systemic manifestations of DIHS are responsible for a 10% mortality rate.
