Hyperkalemia is an infrequent complication of the therapy of malignant disease. In previously reported cases, hyperkalemia following the institution of chemotherapy has been associated with acute renal failure. In this report, we present a patient with chronic lymphocytic leukemia who developed hyperkalemia following splenic irradiation. Necrosis of tumor(More)
The DIC syndrome is the most common cause of an abnormal hemorrhage tendency during pregnancy and the puerperium and reflects systemic activation of the coagulation cascade by circulating thromboplastic material, with secondary activation of the fibrinolytic system. Its presence in a pregnant patient almost invariably is evidence of an underlying obstetric(More)
Phosphoribosyl pyrophosphate synthetase has been purified extensively from rat liver. Gel filtration studies indicate that the enzyme is a complex of large molecular weight. On electron microscopy, stacking of enzyme molecules into long, linear aggregates is observed. The subunit molecular weight is 40,500, as measured by disc gel electrophoresis in sodium(More)
Das Zervixkarzinom gehört neben dem Mammakarzinom mit einer Inzidenz von 0,01–0,05% unter den Schwangeren zu den häufigsten Malignomen in der Schwangerschaft. Eine vertikale Metastasierung konnte beim Zervixkarzinom nicht beobachtet werden. Die Symptomatik ist innerhalb und außerhalb der Schwangerschaft vergleichbar. Eine histologische Abklärung ist bei(More)
An adult patient with acute lymphoblastic leukemia associated with a 14q+ marker chromosome is presented. The abnormality resulted from a translocation of material from the long arm of chromosome 11. The leukemic cells were found to be B cells on the basis of surface immunoglobulins, lack of receptors for sheep erythrocytes, and a characteristically low(More)
A patient with severe anemia, reticulocytopenia, and erythroid hyperplasia of the bone marrow developed fatal acute nonlymphocytic leukemia after 3 yr. A Philadelphia chromosome with the typical 9/22 translocation t(9q +;22q-) was identified by banding techniques in a small number of bone marrow cells throughout the preleukemic phase of the illness(More)
