Measurement of spinal shrinkage (stadiometry) has been suggested to be a convenient measure of low-back load in workplace settings. This report documents three separate experiments that collectively form a central theme: Is the measurement of spinal shrinkage a suitable assessment technique to quantify the cumulative effect of loading on the low back given(More)
OBJECTIVE To investigate the influence of corticosteroid pulse (CP) therapy on soluble interleukin 2 receptor (sIL-2R), interleukin 6 (IL-6) and IL-8 levels in patients with active rheumatoid arthritis (RA). METHODS Twenty-five patients with active RA were studied before and after treatment with intravenous CP therapy. In 12 patients lymphocyte subsets(More)
Sex steroids are believed to modulate the immune system in rheumatoid arthritis (RA). Since receptors for sex steroids are present on T-lymphocytes, which are thought to play a major role in the pathogenesis of RA, it is suggested that gonadal steroids can mediate their immunomodulating effect directly on T-lymphocytes. Recently a specific method for(More)
OBJECTIVE To investigate whether oestrogens can be used as treatment to diminish disease activity in women with rheumatoid arthritis. METHODS Forty postmenopausal female patients with active rheumatoid arthritis participated in a placebo-controlled, double-blind study on the possible beneficial effect of adjuvant treatment of oestradiol on disease(More)
According to the EU Directive 2006/17/EC, European tissue banks are required to perform a physical examination on every potential tissue donor. The directive itself, however, does not specify the content of this examination. The aim of this study was to investigate the current practice of physical examination in European tissue banks. A questionnaire was(More)
OBJECTIVE To investigate the effects of syncytiotrophoblast microvillous membranes (STBM) in concentrations, found in vivo in women with pre-eclampsia, on endothelial function in isolated resistance arteries. SETTING Department of Obstetrics and Gynaecology, Huddinge University Hospital, Stockholm. SAMPLE Twenty-nine myometrial resistance arteries(More)
BACKGROUND After the largest outbreaks of Q fever ever recorded in history occurred in the Netherlands, concern arose that Coxiella may be transmitted via donated tissues of latent or chronically infected donors. The Dutch Health Council recently advised to screen tissue donors, donating high risk tissues, for Coxiella infection. METHODS After validation(More)
PURPOSE To identify risk factors for the occurrence of bleeding complications after enucleation for cornea donation, in order to develop preventive activities to reduce the occurrence of bleeding complications and especially the development of ocular hematomas. METHODS From all Dutch cornea donors deceased in the year 2006, donor characteristics,(More)
To estimate the mechanical load on the low back in manual materials handling, the Static Strength Prediction Model (SSPM, University of Michigan) is widely used in the occupational field. It requires (for practical reasons) only a small number of input variables (five body segment angles, standing height, total body mass, external load on the hands) on(More)
The European Association of Tissue Banks (EATB) donor case workshop is a forum held within the program of the EATB annual congress. The workshop offers an opportunity to discuss and evaluate possible approaches taken to challenging situations regarding donor selection. Donor case workshops actively engage participants with diverging background and(More)
