The administration of more vials of antivenin is potentially associated with negative outcome; however, a causal relationship has not been established. Controlled, prospective studies are needed to optimize antivenin administration.
Six domestic shorthair cats, aged three to four years and weighing 5.1 to 7.4 kg, were used to assess the thermal antinociceptive effect of a transdermal buprenorphine patch, designed to supply 35 mug buprenorphine/hour, which was applied to the shaved thorax. The cats' thermal thresholds were tested before the patch was applied and two, four, six, eight, 10, 12, 14 and 16 hours after it had been applied, and then every six hours until it was removed after 72 hours, and for a further 24 hours afterwards. Blood was collected at each time to measure the plasma concentration of buprenorphine. The patches did not produce a significant change in the thermal thresholds of the cats throughout the testing period. The mean (sd) peak plasma buprenorphine concentration was 10 (0.81) ng/ml.
Iron is an essential element for nearly all living organisms and disruption of iron homeostasis can lead to a number of clinical manifestations. Iron is used in the formation of both hemoglobin and myoglobin, as well as numerous enzyme systems of the body. Disorders of iron in the body include iron deficiency anemia, anemia of inflammatory disease, and iron overload. This article reviews normal iron metabolism, disease syndromes of iron imbalance, diagnostic testing, and treatment of either iron deficiency or excess. Recent advances in diagnosing iron deficiency using reticulocyte indices are reviewed.
Ingestion of albuterol can lead to profound physical and serum biochemical abnormalities. Appropriate historical information should be obtained to identify possible sources and routes of exposure to intoxicants. Albuterol-induced hypokalemia can be successfully managed medically.
This report describes concurrent hypertension in a dog with a functional thyroid gland adenocarcinoma with subsequent return of blood pressure values to within reference ranges after thyroidectomy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
