[Does the sickle cell trait (heterozygous carrier status) confer protection against malaria?]. / L'hémoglobine S protège-t-elle du paludisme ?

The high frequency of the gene for sickle-cell hemoglobin in malaria-endemic regions is believed to be due to an advantage in surviving malaria. We report the case of a woman with both malaria and hemoglobin S.

[Acute myocarditis and inflammatory bowel diseases: a case series of two patients]. / Les myocardites aiguës compliquant les maladies inflammatoires chroniques de l'intestin: à propos de deux observations.

INTRODUCTION: Acute myocarditis is one of the less common extra-intestinal manifestations of inflammatory bowel diseases (IBD). It may reveal IBD or occur during the follow-up. CASE REPORTS: We report two patients who presented an acute myocarditis associated with ulcerative colitis that reveal the disease in one of them. Clinical features at presentation were non specific and both patients presented with chest pain. Diagnosis was obtained with cardiac MRI. Outcome was favourable in the two patients. CONCLUSION: Etiologies of myocarditis are various and the diagnosis of extra-intestinal manifestations related to IBD remains a diagnosis of exclusion. Cardiac MRI is an important diagnostic tool. Colchicine and acétylsalicylic acid are commonly prescribed in a first therapeutic approach.
