The other great imitator among infectious diseases: Leptospirosis.

INTRODUCTION: Leptospirosis is a worldwide zoonosis responsible for highly diverse clinical presentations with a wide range of severity. Variable environment exposures to infected urines of rodents have been described. OBSERVATION: We report five cases of serologically confirmed leptospirosis leading to hospitalization in an intensive care unit (ICU) of a French center. These patients displayed neurological, respiratory, and abdominal presentation of leptospirosis with variable level of severity. Either professional, leisure related, or daily living exposures have been retrieved. CONCLUSION: These cases underline the diversity of clinical presentation and environmental exposure of this infectious disease. They highlight the interest of an exhaustive anamnesis with collection of professional activity, environmental exposures, and leisure activities.

Life-threatening chlorpromazine-induced acquired haemophilia A in a patient with a cavernous malformation involving the medulla oblongata.

INTRODUCTION: Chlorpromazine is a commonly used drug in several medical conditions associated with a wide range of side effects. Few cases of hemostatic disorder have been reported in the literature. CASE REPORT: A 39-year-old man had previously been diagnosed with a cavernous malformation of the medulla oblongata. Chlorpromazine was started to treat persistent hiccups. Twenty days later, the patient presented hepatitis and a pruritic rash. Haemostasis tests revealed a prolonged partial thromboplastin time associated with isolated decrease of factor VIII level and anti-factor VIII antibodies. Magnetic resonance imaging revealed recent asymptomatic bleeding. Introduction of eptacog alfa and prednisone allowed clinical and biological improvement as well as a prolonged remission after 12 months of follow-up.
