[Atypical urticaria disclosing acute basophilic leukemia. Apropos of a case associated with hyperhistaminemia].

Acute basophilic leukaemia (ABL) is a rare disease characterized by high fever, anaemia and haemorrhagic diathesis. Its prognosis is somber and its response to therapy mediocre. Death is mainly due to cerebral or digestive hemorrhage and coronary disease.

Impaired phagocytic activity of neutrophils in patients receiving haemodialysis: the critical role of iron overload.

The metabolic burst (as measured by the spontaneous and stimulated nitroblue tetrazolium tests), the phagocytosis of heat inactivated bakers' yeast and of Staphylococcus aureus, the killing of Staph aureus, and the myeloperoxidase activity of polymorphonuclear neutrophils were studied in 11 patients receiving maintenance haemodialysis. Of these patients, six were polytransfused and had high serum ferritin concentrations (mean 5940 (SD 2925) micrograms/l; group 1), and five had normal serum ferritin values (mean 171 (116) micrograms/l; group 2). Patients in group 1 had a history of more infectious episodes (0.

Fanconi's anaemia. Simultaneous onset in 2 siblings and unusual cytological findings.

Fanconi's anaemia is reported in 2 siblings. The simultaneous onset of pancytopenia after possible exposure to common external agents suggest that both a frail genotype and environmental factors may be etiologically involved in the disorder. One of the children died after having developed a monoblastic leukaemia.
