[Comparison of 3 high-permeability dialysers].

Three capillary dialyzers, with highly permeable membranes, have been compared for their capacity of epuration of blood urea nitrogen, creatinine, phosphorus, uric acid and beta 2 microglobulin, and for their respective protein losses. There were very little differences between the dialyzers for epuration of small uremic molecules, with no benefit due to high permeability membranes in comparison with conventional dialyzers. Protein losses may be important and have to be known. About beta 2 microglobulin, filtered quantities are not correlated to changes in serum levels, suggesting the presence of other mechanisms (adsorption on the membrane and generation during hemodialysis) which influence, together with epuration, perdialytic changes of serum beta 2 microglobulin concentrations.

[Association of autoimmune thrombopenic purpura and leiomyoma. Recovery after excision of the tumor].

A case of auto-immune thrombocytopenic purpura in a woman with benign cystic leiomyoma in Retzius' space is reported. The platelet Coombs' test was positive on platelets; the indirect Coombs' test was negative on serum but strongly positive on cyst fluid. Following excision of the leiomyoma thrombocytopenia rapidly subsided and the serological findings became negative, which strongly suggests that the antibody was produced by the tumour.

[Hemoglobin E: report of the first 2 cases in French subjects].

Hemoglobin E has been discovered casually in the blood of two French donors: one coming from the Alsace region, the other one coming from the Champagne region. In the two cases, the hemoglobin E is in an heterozygote state and takes the place of 33 per cent of the total haemoglobin in the first and 24 per cent in the second. We investigated in their families and found that other members of these families had hemoglobin E. Each time, it was associated with a microcytosis and polycythaemia without anemy or iron deficiency. The red cells morphology shows many microspherocytes and target-cells. There is no relationship between these two families and the research of an asiatic antecedent proved negative. These two observations give a supplementary proof that the geographic repartition of the hemoglobin E is larger than what we read in the first publications and shows the interest to study the hemoglobin of unexplained polycythaemia with microcytes in the blood of blood donors.
