One- to 2-day-old medaka (Oryzias latipes) larvae were exposed for 4 days to the rice field pesticides methyl parathion, molinate, carbofuran and a mixture of all three. Pesticide concentrations were one-half the 96 h LC50 ("high concentration") and levels approximating those measured in receiving waters from rice field runoff ("low concentration"). Maximum(More)
BACKGROUND Anti-microbial lock solutions (AML), in conjunction with systemic antibiotics, may successfully treat tunnelled haemodialysis catheter-related bloodstream infections (CR-BSI). It is unknown whether AML promote anti-microbial resistance. METHODS This is a retrospective cohort study of all CR-BSI (2003-2006) in our dialysis unit. Controls (n =(More)
The effects of acetazolamide administration on arterial blood acid-base equilibrium and electrolyte concentrations were evaluated in 13 clinical patients and in a 4-week experiment in 6 conditioned mixed-breed dogs. Findings included persistent acidemia characterized by hyperchloremic metabolic acidosis, elevated partial pressure of oxygen, and mild(More)
Elderly patients form the most rapidly expanding group of hemodialysis (HD) patients in Europe and the United States. There are initiatives to promote an increase in arteriovenous fistula (AVF) formation. There are concerns that elderly patients may have lower rates of surgical vascular access compared with younger patients due to risks of higher(More)
A 3-year-old boy, who developed the signs and symptoms characteristic of Kawasaki disease, is described. The child also had an 8 cm tender hepatomegaly. Hydrops of the gallbladder could not be shown. Liver biopsy showed marked infiltration of inflammatory cells, including neutrophil and eosinophil leucocytes in the portal tracts involving the periphery of(More)
Two female rhesus macaques (Macaca mulatta) and one female pigtailed macaque (M. nemestrina) developed acute neurological signs including ataxia, muscular incoordination, and seizures. Light microscopy showed Cowdry Type A intranuclear inclusion bodies in astrocytes and neurons of the cerebral cortex and Purkinje's cells of the cerebellum. Many cells also(More)
The Acute Surgical Unit (ASU) is a recent change in management of acute general surgical patients in hospitals worldwide. In contrast to traditional management of acute surgical presentations by a rotating on-call system, ASUs are shown to deliver improved efficiency and patient outcomes. This study investigated the impact of an ASU on operative management(More)
Protein-calorie malnutrition is commonly found in chronic CAPD patients and is a matter of concern since low serum albumin levels correlate with an increased risk of morbidity and mortality. Recognition of this link has therefore led to a growing interest in the efficacy of IPAA therapy as a possible treatment option. The present case study took place(More)
