RESUMO

Tyrosine kinase inhibitors represent today's treatment of choice in chronic myeloid leukemia (CML). Allogeneic hematopoietic stem cell transplantation (HSCT) is regarded as salvage therapy. This prospective randomized CML-study IIIA recruited 669 patients with newly diagnosed CML between July 1997 and January 2004 from 143 centers. Of these, 427 patients were considered eligible for HSCT and were randomized by availability of a matched family donor between primary HSCT (group A; N=166 patients) and best available drug treatment (group B; N=261). Primary end point was long-term survival. Survival probabilities were not different between groups A and B (10-year survival: 0.76 (95% confidence interval (CI): 0.69-0.82) vs 0.69 (95% CI: 0.61-0.76)), but influenced by disease and transplant risk. Patients with a low transplant risk showed superior survival compared with patients with high- (P<0.001) and non-high-risk disease (P=0.047) in group B; after entering blast crisis, survival was not different with or without HSCT. Significantly more patients in group A were in molecular remission (56% vs 39%; P=0.005) and free of drug treatment (56% vs 6%; P<0.001). Differences in symptoms and Karnofsky score were not significant. In the era of tyrosine kinase inhibitors, HSCT remains a valid option when both disease and transplant risk are considered.

RESUMO

Congenital adrenal hyperplasia due to 21-hydroxylase deficiency is a disorder with different clinical manifestations, that results from mutations in the P-450(c21) gene. Direct sequence analysis of P-450(c21) genes in a family demonstrates that patients with different clinical forms of congenital adrenal hyperplasia can have identical P-450(c21) genes, suggesting that other effects play a role in developing the different clinical forms.

RESUMO

A girl at the age of nearly 13 years with a haemodynamic insignificant defect of the ventricular septum fell ill with a staphylococcal endocarditis of the aortic valve. After a high dosage therapy with oxacillin for some weeks occurred a leucocytopenia which was reversible after discontinuation of this therapy. Because we could find only few reports about this problem in the german literature, we will report about our patient and give a short survey of literature.

RESUMO

A latex agglutination test (SeroSTAT Staph; Scott Laboratories, Fiskeville, R.I.) and two hemagglutination tests (Staphyloslide; BBL Microbiology Systems, Cockeysville, Md.; and Hemastaph; Remel, Lenexa, Kans.) were compared with the slide coagulase (SC) and tube coagulase (TC) tests at room temperature (22 to 25 degrees C) and at 37 degrees C for the rapid identification of Staphylococcus aureus. A total of 380 clinical strains of staphylococci were tested. The TC test performed at room temperature yielded the largest number of TC-positive results (n = 239), and based on this observation 239 organisms were classified as S. aureus and 141 were classified as non-S. aureus. The SC, TC (37 degrees C), SeroSTAT Staph, Staphyloslide, and Hemastaph tests correctly identified 210 (87.9%), 221 (92.5%), 238 (99.6%), 239 (100%), and 236 (98.7%) of the S. aureus isolates, respectively. Of the S. aureus isolates that were TC positive at room temperature 68% required 24 h of incubation before coagulase production was detected. There was one false-negative SeroSTAT Staph result and one false-negative Hemastaph result. The Staphyloslide test yielded two noninterpretable results (both organisms were later confirmed as non-S. aureus), whereas there were six noninterpretable results recorded with the Hemastaph test (four organisms were classified as non-S. aureus, and two were classified as S. aureus). The SeroSTAT Staph, Staphyloslide, and Hemastaph tests were all more sensitive than the conventional SC and TC (37 degrees C) tests and were considerably more rapid than the TC test at either temperature.

RESUMO

The energy distribution of 3H(d, n)4He neutrons from a neutron therapy facility has been studied in different depths in a lucite phantom with two methods. Thin foils of 8 different target materials with well-known excitation functions and reaction thresholds between 1.8 and 12.6 MeV for the reactions to be observed have been activated. Secondly, recoil proton spectra have been measured with a small stilbene crystal. In both cases neutron energy spectra have been determined with unfolding methods. The two techniques are compared with respect to the application in neutron dosimetry and for monitoring purposes in neutron therapy.
