A new sampling system has been developed for the measurement of time-averaged concentrations of organic micropollutants in aquatic environments. The system is based on the diffusion of targeted organic compounds through a rate-limiting membrane and the subsequent accumulation of these species in a bound, hydrophobic, solid-phase material. It provides a(More)
The predominant potential pathogens in the vaginal flora, sampled before operation in 41 patients undergoing gynaecological surgery, included E. coli, alpha-haemolytic streptococci, Streptococcus faecalis, anaerobic Gram-positive cocci and Bacteroides fragilis. All the aerobic Gram-negative bacilli and 89.7 per cent of the streptococci isolated were(More)
Passive sampling systems are an emerging technology for detecting pollutants in the aquatic environment. A passive sampling system has been developed based on diffusion through a porous surface to a receiving phase, where the analyte is removed by chelation at a solid phase. The diffusion process can be described by Fickian diffusion through the sampler.(More)
A 3-1/2-year-old girl was diagnosed as having a mediastinal endodermal sinus tumor with pulmonary, bony, and hilar lymph node metastases. Following 7 months of treatment with chemotherapy, thoracic CT (computerized tomogram) scan showed the presence of a residual mass. Upon further surgical exploration the residual mass, which was found to be(More)
We report a patient with Ehlers-Danlos syndrome and mitral valve endocarditis. The case was complicated due to the initial septic status of the patient and the fragility of the mitral valve both of which required further early operative intervention. The patient also had pre-existing pulmonary septic emboli, the significance of which was missed prior to the(More)
