Cocaine snorting may induce ocular surface damage through corneal sensitivity impairment.

Purpose: Cocaine abuse may cause severe ischemic and necrotic tissue damage in several organs, including the eye. However, the cornea is an avascular tissue relying on sensitive nerves for its trophic support, and the pathogenesis of cocaine-induced corneal lesions is unclear. In this study, we aimed to investigate if corneal sensitivity, ocular surface, and tear function are damaged by habitual cocaine snorting.

Background: Headache is one of the most common symptoms after cocaine use.

Methods: We investigated headache frequency and characteristics and the correlation between headache and acute cocaine intake in a cross-sectional study in a consecutive series of chronic cocaine users.

Results: Participation rate was 94.

Anisakiasis and gastroallergic reactions associated with Anisakis pegreffii infection, Italy.

Human cases of gastric anisakiasis caused by the zoonotic parasite Anisakis pegreffii are increasing in Italy. The disease is caused by ingestion of larval nematodes in lightly cooked or raw seafood. Because symptoms are vague and serodiagnosis is difficult, the disease is often misdiagnosed and cases are understimated.
