Envenomation by the Bothrops lanceolatus, a snake found only in Martinique, leads to swelling and pain, and occasionally to systemic signs and/or coagulopathy. Severe thromboses at some distance from the site of the bite may appear within 48 hr. Uncertainties as to the actual development of thrombotic complications in patients appearing to be suffering from(More)
Onset of adult T-cell leukemia (ATL) usually follows a long period of viral latency. Strongyloides stercoralis infection has been considered a cofactor of leukemogenesis. Hypereosinophilia (HE) is also observed and could be associated with either the presence of parasites or the leukemic process. In non-Hodgkin's lymphoma, eosinophilia may or may not affect(More)
BACKGROUND The severity of envenoming from Bothrops lanceolatus is determined by the development of cerebral, myocardial or pulmonary infarctions, and occasionnaly by serious local envenoming. Introduction of specific antivenom has resulted in a dramatic improvement in the prognosis of this envenoming. Against this background, we report 3 recent cases of(More)
The correlation between clinical grading of patients bitten by Bothrops lanceolatus and the subsequent development of their envenoming was examined. Severity of envenoming was graded using a 1-4 scale (minor to major). Patients were classified into 2 groups according to the time elapsed between bite and treatment with a specific purified equine F(ab')2(More)
Recurrent intravenous leiomyoma extending to the right heart chambers is extremely rare. A large range of surgical techniques and approaches (i.e. two-step procedure, hypothermia and circulatory arrest) have been previously described. We report a recent case where the tumour was excised in a one-step procedure under normothermic cardiopulmonary bypass. This(More)
An enzyme-linked immunosorbent assay was developed to measure venom antigen levels in the serum of 40 patients bitten by Bothrops lanceolatus. The grading system used for the severity of envenomation (grades 1 to 4, minor to major) was predominantly based on the presence of local signs. Serum venom levels increased with the grade of severity (P < 0.001, by(More)
Patients with valvular myxoma are usually candidates for surgery because of the high incidence of life-threatening embolism. In some cases, the tumor is sessile or presents with a large peduncle: complete excision may then lead to valve replacement. We report two cases of atrioventricular valve myxoma where replacement was avoided. In one patient, a mitral(More)
