A family survey was conducted among 909 patients with leukaemia of all types,
with the purpose of establishing the incidence of further cases of leukaemia
among relatives.Among a total of 41,807 relatives 8,349 were deceased, and the
cause of death was objectively confirmed in 5,011.72 patients had one or more
relatives with leukaemia. First degree relatives with leukaemia were much more
frequent ... hiện toàn bộ
Eight commercial heparin preparations were examined by the method of Born &
Cross. All preparations induced aggregation of washed human platelets in the
presence of calcium, probably by inducing release of platelet ADP. The
aggregating potency varied considerably from brand to brand.
The value of preoperative haemostatic screening tests in prediction of surgical
bleeding was examined in 101 patients, mainly with abdominal and thyroid
lesions. The study demonstrated complete lack of correlation between the
preoperative evaluation of bleeding risk and the observed surgical bleeding (X2
test P ∼ 0.85).
In six cases of the cold haemagglutinin syndrome, the isolated cold
haemagglutinin was electrophoretically markedly homogeneous when compared with
the total γ1‐macroglobulin of the same sera and consisted of group I molecules
only. In three of the cases, individually specific antigenic determinants were
demonstrated on the isolated cold haemagglutinin. These determinants were
unrelated to the anti... hiện toàn bộ

The authors describe the haematologic findings in a man aged 61, who for two
years has been under observation with a syndrome of thrombocytopenia, regularly
alternating with thrombocytosis of a very regular interval of 39 days. This
tidal fluctuation of the platelet counts was within the range 10,000–900,000/μl.
There was a synchronous fluctuation of the megakaryocyte numbers in the bone
marrow, m... hiện toàn bộ
A patient with cyclic changes in circulating platelet level is reported, and the
literature on this cyclic phenomenon is discussed. Platelet and menstrual cycles
occurred independently. In our patient and several others reviewed herein, the
cycling of the platelet level is probably related to cyclic changes in platelet
production. We speculate that these production changes result from the action o... hiện toàn bộ

36 acute leukaemias in children, 24 lymphoblastic and 14 myelogenic, have been
examined with a set of 10 monoclonal antibodies by indirect fluorescent
staining. In the lymphoblastic group the leukaemic cells of 4 children were
found to have T‐cell phenotype, while 19 of the other 20 T‐cell phenotype
negative cases were found to be positive for the c‐ALL antigen. All 20 were
negative for surface im... hiện toàn bộ
The authors report a patient treated for 3 years with chlorambucil for
scleroderma. This apparently produced a preleukaemic sideroblastic anaemia and
acute leukemia. This point out the consequences of the employment of
immunodepressive agents.
In a case of cold agglutinin syndrome, treatment with melphalan resulted in
marked decrease of cold agglutinin titre, decrease in concentration of
monoclonal cold agglutinin IgM, and concomitant clinical improvement with
increased cold tolerance. After 27 months of melphalan treatment, the patient
developed acute erythroleukaemia.
This is a case report on a male technician, 37 years of age, who experienced 5
acute episodes of severe thrombocytopenia, which occurred regularly every 21st
day. The bleeding episodes usually lasted 12 days, and the remissions 9 days.
Treatment with corticosteroids and splenectomy had no influence upon the course
of the disease. The bleeding became worse at every episode, and the patient died
