[Paraspecificity of antivenins: example of severe envenomation by the Sahara horned viper (Cerastes cerastes) treated with non-specific antivenin].

Snake bites are a major public health problem in Morocco. Both morbidity and mortality of ophidian envenomation remain very high in this country. Antivenin immunotherapy, the only etiological treatment of this envenomation, is often unavailable in local hospitals.

[Acute negative pressure pulmonary edema: illustration from a unusual clinical case following a postoperative recurrent laryngeal nerve palsy].

Acute postoperative negative pressure pulmonary edema (NPPE) is a respiratory complication due to upper airway obstruction occurring most commonly in the postoperative period. Pathophysiologically, NPPE is explained by the abrupt generation of highly negative intrathoracic pressure that lead to fluid transudation from the pulmonary capillaries. This observation reports an unusual case of a young patient who has undergone total thyroidectomy for multinodular goiter.
