[Heavy haematuria as the presentation of attenuated haemophilia B (author's transl)].

The authors report a rare case of eosinophilic cystitis presenting with heavy haematuria which led to the discovery of attenuated haemophilia B. Bleeding and clotting times in this patient, with no past history of haemorrhage, were normal. Complete coagulation studies led to the diagnosis in the presence of poor plasma prothrombin consumption and a moderate deficit in clotting factor IX, defining haemophilia B.

[Comparative study of a factor-VIII inhibitor in a non-hemophylic patient and in a patient with hemophylia A gravis].

In this study, we tried to make a comparison between the findings concerning two human strong anti Factor VIII inhibitors. In one case, the strong inhibitor appeared in an old man without any particular antecedant. In the second case, it occurred in a young hemophiliac A.

[Cerebromeningeal hemorrhages and their sequelae in congenital deficiencies of plasma hemostasis factors. Apropos of a case of Stuart factor deficiency with early cerebromengeal hemorrhage leading to hydrocephalus with considerable psychomotor retardation].

We have taken an interest in cerebro meningeal haemorrhages in congenital plasmatic coagulation Factor deficiency with out obvious traumatic origin. We have observed such accidents in a new born child with congenital Stuart factor deficiency and in four cases of haemophilia A. It seems from our experience and from the literature that such haemorragic accidents are not particularly frequent in congenital coagulation deficiency and contribute only for a few to creation of a psychomotor inadapted population.
