[Hemolytic anemia after voluntary ingestion of henna (Lawsonia inermis) decoction by a young girl with G6PD deficiency].

Henna (Lawsonia inermis) is a shrub bearing leaves that are crushed and used for cosmetic purposes in Asia and Africa. In several countries, henna decoction is ingested as a traditional drug to induce abortion. One component of Henna, known as Lawsone, can induce hemolysis in G6PD-deficient patients after cutaneous exposure or ingestion.

[Acute necrotizing pancreatitis and complete atrioventricular block complicating the course of ascaris infection in an adult patient].

Ascaris lumbricoides, a large round nematode, which causes human ascariasis, is the most prevalent helminth in the world. Ascariasis is usually asymptomatic but can cause serious complications, with a mortality rate of 5%. We report a 55-year-old woman from Comoros who presented with ascariasis complicated by occult cholangitis, severe acute pancreatitis, and transient complete heart-block.

Behçet's disease in East African patients may not be unusual and is an HLA-B51 negative condition: a case series from Mayotte (Comoros).

Objective: We aimed to report the presence of Behçet's disease in patients of East African ancestry, where there have been very few reports of the disease.

Methods: Case series of 14 patients, all of whom were born in the Comoros, reporting to the single primary general medicine department of Mayotte's island since 1998. All the patients but one satisfied the international group study criteria for Behçet disease.
