BACKGROUND Routine examinations have a low specificity and a low positive rate for the diagnosis of peritoneal lesions. This study aimed to evaluate the diagnostic value and safety of ultrasound-guided percutaneous peritoneal lesion biopsies in patients with ascites and/or abdominal distension with unclear causes. METHODS A retrospective analysis was performed in 153 consecutive patients with...
BACKGROUND Rheumatic diseases are a major cause of permanent work disability. In the process of occupational rehabilitation several health professionals may have a role. OBJECTIVE To assess the quality and quantity of communication and cooperation between Dutch rheumatologists and occupational physicians. METHODS A postal survey among 187 Dutch rheumatologists. RESULTS 153/187 rheumatolog...
BACKGROUND One of the most serious human health concerns related to environmental contamination with polychlorinated biphenyls (PCBs) is the presence of these chemicals in breast milk. OBJECTIVES We developed a physiologically based pharmacokinetic model of PCB-153 in women, and predict its transfer via lactation to infants. The model is the first human, population-scale lactational model for...
Emerging evidence indicates that polychlorinated biphenyls (PCBs) are involved in the development of diabetes mellitus in the obese. The purpose of this study was to determine mechanisms by which PCB 153 (2,2´,4,4´,5,5´-hexachloro-biphenyl) could influence diet-induced obesity and insulin resistance during adipogenesis. Lineage of h-ADMSCs was differentiated either as control (differentiation m...
OBJECTIVE Recent studies indicate that persistent organohalogen pollutants (POPs) may contribute to sex ratio changes in offspring of exposed populations. Our aim in the present study was to investigate whether exposure to 2,2 ,4,4 ,5,5 -hexachlorobiphenyl (PCB-153) and dichlorodiphenyldichloroethene (p,p -DDE) affects sperm Y:X chromosome distribution. SUBJECTS AND METHODS We obtained semen ...
No scientific data is available on emerging contaminants like brominated flame retardant (BFRs) including polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyl (BB 153) levels in the abiotic environment of Fiji Islands. Concentrations of PBDEs and BB 153 were determined in soil and sediment from various land-use types from Fiji Islands. Generally, total concentrations of PBDEs and ...
BACKGROUND AND PURPOSE Chinese have been reported to have an extremely low prevalence rate of carotid and vertebral artery disease in comparison with whites. Previous studies, however, have been limited to general hospital stroke admission or postmortem series and were prone to selection bias. Extracranial cerebrovascular disease (ECCVD) is associated with coronary artery disease (CAD) in white...
The effects of in vitro exposure to different organochlorines were evaluated on immune functions of beluga whale peripheral blood leukocytes and splenocytes. The effects of different concentrations of four different congeners of PCBs (138, 153, 180, and 169) as well as two DDT metabolites (p,p'-DDT and p,p'-DDE) were evaluated on phagocytosis and cell proliferation. The effects of dioxins and m...
Excretion and tissue retention of a coplanar and a non-coplanar hexachlorobiphenyl (HxCB) were determined 48 h after a single intraperitoneal (ip) dose of 8 mg/kg radiolabeled [14C]-HxCBs to weanling male and female Long-Evans rats. The objective was to understand the involvement of initial target organs of chlorobiphenyl (CB) accumulation following acute exposure in immature animals. During th...
