Orthopaedic patients hospitalized for surgery or confined to bed are at high risk for constipation. To determine if wheat bran ingestion would result in more stools, less laxative use, and a lower incidence of constipation after orthopaedic surgery, 16 orthopaedic patients were randomly assigned to experimental and control groups for 7 days. The study(More)
There is a strong interest in using LEDs for general illumination due to the potential they offer for energy saving, environmental friendliness, new opportunities in lighting design, and control of the intensity, colour, and spatial distribution of light. General illumination requires primarily white light that can be obtained by mixing e.g. the light of(More)
Dementia is significant loss of intellectual abilities such as memory capacity, severe enough to interfere with social or occupational functioning. The most common types of dementia are: Alzheimer's disease (AD), Lewy body dementia (LBD), and frontotemporal dementia (FTD). In 2008, there are currently 29.8 million people with dementia, with the number(More)
The authors investigated the tubulointerstitial changes (atrophic tubuli, interstitial fibrosis and round-cell infiltration) by two methods in renal biopsies from 56 patients with IgA glomerulonephritis. A statistically significant correlation was found to exist between the tubulointerstitial changes and serum creatinine level at the time of renal biopsy. A(More)
The goal of this master thesis is to develop new drive and control solutions, for creating white light from mixing the light of different–color LEDs, aiming at a reduced component count resulting in less space required by the electronics and lower cost. It evaluates the LED driver concept proposed in the Philips patent application WO2007/125466 and the(More)
The transverse diameter of the chest and heart was measured in 745 newborn infants after birth asphyxia. Both diameters showed a good correlation with birth weight. The great individual variations of the measurements were due to different degrees of birth asphyxia observed in the infants and to their different responses to compensate asphyxia. A wet lung(More)
A 24-year-old woman with a twin pregnancy had a premature rupture of membranes (PROM) of the first foetus in the 16th gestational week (gw). After 9 days the umbilical cord prolapsed. In the 17th gw the foetus was extracted by vaginal hysterotomy, because of an inferior anterior wall placenta. The patient remained hospitalised receiving tocolysis, lung(More)
The obstetric-perinatologic problems raised by premature rupturing of the membranes in the 22nd gestational week is presented in the form of a case report from the Perinatal Centre of the University of Cologne. By close ultrasonic monitoring of the course of development, measurement of parameters of inflammation and administration of prophylactic(More)
The morphology of the lungs and heart was analysed in 824 newborn infants with normal cardiorespiratory adaptation. Under normal conditions, the air content of the lungs became satisfactory in the first 6--12 hours and normal in all cases after 24 hours. The values for the transverse diameter of the chest and heart were brought into correlation with birth(More)
