[Acute transformation in 45 cases of chronic myeloid leukemia].

After a chronic phase, the average duration of which in this series was 38 months, the acute phase of myeloid leukemia was very short, not exceeding 7 months. The clinical signs which suggest an acute exacerbation are, in order of importance, increase in the volume of the spleen, changes in general health, fever. The blood signs, which are often found later than the clinical signs, are increased white cell count, anemia and marrow leukoblastosis higher than 20%. The laboratory criteria of acute exacerbation are of lesser importance. Chemotherapy gives very poor results at this stage.

Hemoglobin Cochin-Port-Royal: consequences of the replacement of the beta chain C-terminal by an arginine.

Hemoglobin Cochin Port-Royal beta 146 (HC3) His yields Arg is the second example in which the beta C-terminal residue is replaced. Owing to the known importance of His beta 146 in the co-operative effects of hemoglobin, the functional properties of this variant were carefully studied. It had a normal Hill coefficient but a reduced alkaline Bohr effect. However, the reduction in Bohr effect is less than the halving predicted from previous mutants and modified hemoglobins.

[Infections during malignant blood diseases. Value of the carbenicillin-gentamicin combination].

The association of carbenicillin and gentamicin was used as a routine in the early treatment of 48 attacks of fever, in 38 patients who mostly had acute leukemia and marrow aplasia. The attacks of infection may be classified as follows: 30% septicemia, 30% local infections, 40% no bacteria were identified. Among the septicemias, we noted 5 septicemias due to pyocyaneus, 4 due to klebsiella. On the whole, in the attacks of fever, the association of carbenicillin and gentamicin proved effective in 70% of cases, but a cure was obtained in only 56% of cases. In vitro, the association carbenicillin-gentamicin proved justified in 70% of cases. There was no special intolerance, apart from a few cases of hypokalemic alkalosis. The association carbenicillin-gentamicin, by its broad spectrum and especially in view of its elective effect on the pyocyaneus is an excellent initial form of antibiotic therapy, when faced with infection in a patient with malignant blood disease. However, it should be recognised that the efficacy of this association depends on the number of circulating polynuclear cells and that some bacteria, such as the klebsiella, are clear cells and that some bacteria, such as the klebsiella, are often resistant to this antibiotic association.
