NCT00886639
The aim of this study is to investigate the six-minute-walking-distance of COPD-patients with breathing oxygen in comparison to breathing normal air. Patients, who increase their walking-distance about more than 15% or 35m only because of breathing oxygen, are so-called "Oxygen Responders." The study is aimed to find attributes of Oxygen Responder and to investigate, if a patient can change the "respond" with higher performance and endurance.
NCT00570817
Infusions with high-dose methotrexate 5 g/m2 or 8 g/m2 are used to treat children with acute lymphoblastic leukemia (ALL), non-Hodgkin's lymphoma, medulloblastoma and ependymoma. Methotrexate is primarily excreted unchanged by the kidney where it can course acute kidney damage resulting in prolonged time of excretion of the drug. Our main hypothesis is that 12 hours of intravenous hydration before the methotrexate infusion is more efficacious in preventing methotrexate induced kidney damage compared to four hours of hydration.
NCT01287442
It is well established to assess the functionality of a filtering bleb by intraocular pressure (IOP), either as an absolute value or as a percent reduction, and by the need of additional antiglaucoma drugs. It is also possible to evaluate the appearance of a bleb by a clinical score, e.g. the "Wuerzburg bleb classification score" (WBCS). The purpose of this study was to find out whether there is a correlation between clinical findings, in particular IOP and the WBCS. 100 eyes within two years after trabeculectomy were included into the study. Using colour photographs the filtering bleb was evaluated according to the WBCS from two different examiners, both on different levels of clinical experience. WBCS = 1 indicates poor bleb appearance, WBCS = 15 indicates optimal bleb appearance. At the same time, clinical findings like intraocular pressure, best corrected visual acuity, slit lamp biomicroscopy and medical history were taken by another examiner. * Trial with surgical intervention
