There are about 9403 clinical studies being (or have been) conducted in Switzerland. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Legg-Calvé-Perthes disease is a childhood hip disorder which is common enough to be a significant public health problem (affects 1 in 740 boys between ages 0-14), but uncommon enough to have a sufficient number of patients from a single institution to perform a definitive prospective study comparing the results of current treatments. The present study will establish a database of prospectively identified patients with Legg-Calvé-Perthes (LCP) Disease and collect information regarding their presentation, treatment, and outcomes in the course of receiving currently available treatments. This study seeks to compare the outcomes of current treatments in the management of different age groups (ages 1-6, 6-8, 8-11, >11) of patients with Perthes disease at two- and five-year followup and at skeletal maturity. For each age group, two to three common treatment regimens currently used by practicing pediatric orthopaedic surgeons will be compared. The intervention a patient receives is determined through physician treatment expertise, and is not pre-determined by the study.

Fluorescent lifetime microscopy has emerged as a useful tool to study fluorescent lifetimes in vitro. Fluorescence lifetime represents the average amount of time a fluorophore remains in the excited state following excitation and depends on the fluorophores molecular environment. Fluorescence lifetime ophthalmoscopy (FLIO) is a technique which can quantify fluorescence lifetimes in the human retina in vivo. The purpose of this study is to investigate fluorescence lifetime characteristics in the human retina by using a FLIO. The investigators hypothesize that FLIO will allow to identify areas of retinal metabolic stress such as ischemia by detecting changes in fluorescence lifetimes.
Recently a new method of induce similar hypertrophy in the liver as is observed after hepatectomy has been described and was given the eponym "ALLPS". "ALPPS" stands for Associating Liver Partition with Portal Vein Ligation for Staged Hepatectomy (ALPPS). Since the procedure is used worldwide this international registry was created to enable tracking of cases performed worldwide for safety and outcomes and innovations by the groups involved as well as allows a non-randomized comparison to the conventional methods of portal vein occlusion.
It is the goal of this study adherence and quality of life in a population of people suffering from schizophrenia or schizoaffective disorder and to analyze if these factors are influenced by treatment, support, social services, and residential treatment. The study population is drawn from the the cantons Glarus and Graubunden as well as Liechtenstein.
Recent experimental and clinical studies have shown that platelets play a critical role in liver ischemia and regeneration. Thrombocytopenia, a frequent and potentially serious condition in liver transplantation (LT) recipients, was shown to be associated with postoperative morbidity and mortality after partial hepatectomy. The investigators aim at evaluating whether postoperative low platelet counts are indicators of short- and long-term outcomes after liver transplantation.

The purpose of this study is to determine if repeated sessions of transcranial direct current stimulation (tDCS) are effective for treating chronic subjective tinnitus. Previous studies have reported brief improvements in tinnitus after safe and noninvasive stimulation of the auditory cortex or limbic system. The investigators hypothesize that a greater improvement in tinnitus will be achieved following repeated sessions of tDCS that target both auditory and limbic systems.
The aim of this study is to compare the effects of exercise training and family-based behavioral treatment, either in individual or in group setting, in pre-pubertal children and their mother.
