There are about 5161 clinical studies being (or have been) conducted in Norway. 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.
There is growing evidence that psoriasis is a systemic disorder which enhances atherosclerosis and the risk of cardiovascular disease. Epidemiological studies have shown an independent association between psoriasis and atherosclerosis, stroke and coronary artery disease. The main goal of this on-going study is to register data which will enable the identification of new markers of atherosclerosis activity and carotid plaque instability in patients with severe psoriasis.
All newborn from the period 12.1988 to 31.12.2006 During the two last decades, hip ultrasound has gained acceptance as an accurate screening test for developmental dysplasia of the hip (DDH) and for monitoring the development and treatment of the condition. Debate continues over whether DDH that is detected by ultrasonography is necessarily clinically relevant. The diagnostic accuracy of ultrasound imaging for DDH in the screening population has not been investigated adequately. Studies that investigate the natural course of the disorder, the optimal treatment for DDH, and the best strategy for ultrasound screening are needed. Ultrasound screening at birth for DDH in all newborn infants is standard practice in some European countries but not in the United Kingdom, the United States, or Scandinavia. Evidence is insufficient to support or reject general ultrasound screening of newborns for DDH. (N.F.Woolacott etc 2006, systematic review BMJ) At Vestre Viken HF, Kongsberg, Norway, the investigators implemented universal ultrasound screening in 1998. We will present the long term outcome, including radiographs of the hips after 5-12 years.
Do migrainous vertigo patients have more pathology in their vestibular system than migraine patients without vertigo? The aim of this study is to compare the vestibular system of migraine patients with and without vertigo in the symptom-free period by vestibular function tests, videonystagmography, vestibular evoked myogenic potentials, and subjective visual vertical.
Description of the effect of standard iron supplement on iron status in blood donors Hypothesis: For each person in each group (group a "without iron supplement" or group b "with iron supplement") individual biological variation in reticulocytes, tested day 1 and day 8 will be described. Groups a and b will be compared on iron status from day 1 and day 8. - H1 null: There is no significant intraindividual difference in reticstatus at day 1 and at day 8, in group a. - H2 null: There is no significant intraindividual difference in reticstatus at day 1 and at day 8, in group b - H3 null: There is no significant difference in iron status for the two groups, a and b, at day 1 and at day 8.
