We retrospectively analyzed our chemotherapy results in patients with the Acquired Immunodeficiency Virus syndrome (AIDS) and lymphoma over a 10 year period. Thirty out of 492 (6%) Human Immunodeficiency Virus (HIV) positive patients developed a non-Hodgkin's lymphoma. Thirteen patients with high-grade histology were treated with chemotherapy, 6 patients(More)
We describe a patient who presented with the clinical picture of hairy cell leukemia (HCL). Bone marrow and peripheral blood lymphoma cells showed morphological and immunological features of HCL. Under recombinant alpha-2-interferon (alpha-2-IF) therapy the characteristic morphology changed from HCL to prolymphocytic leukemia (PLL). At diagnosis the(More)
We report on a patient, now 17 year old, in whom lactic acidosis was detected at the age of 7 while attempting to diagnose the causes of increasing weakness. The laboratory examinations revealed elevated pyruvate, alanine and oxaloacetate levels in serum and also a lowered citrate level. This led us to suspect a disturbance of the pyruvate dehydrogenase(More)
Evidence is presented for defective pyruvate dehydrogenase (EC 4.1.1.1) in leukocytes and muscle tissue from a 10-year old child with persistent lactic acidosis, suffering from myasthenia and growth retardation. The defect is expressed in vitro by a depressed stimulation of pyruvate dehydrogenase catalytic activity by exogenous phosphoprotein phosphatase,(More)

Four cases of thanatophoric dwarfism which appeared between 1974 and 1977 are described. Thanatophoric dwarfism was firstly described in 1967. In the mean-time there are reports about 44 cases. The frequency of thanatophoric dwarfism is considered to be 1 to 6393 newborns. There is no clear evidence about the occurrence of thanatophoric dwarfism, chromosone(More)
Until now the clinical identification of the affinity of monoclonal 99mTc-anti-CEA antibodies (MAK BW 250/183) on granulocytes was made with tumor cells carrying the same epitope on NCA-95 and human granulocytes in vitro. As this antibody only binds human granulocytes, animal experiments are impossible. 3 patients had their blood withdrawn within 6 h after(More)
