Wandering kidney in dual-kidney transplant recipient presents a pitfall in the interpretation of renal scintigraphy.

A 26-y-old patient with end-stage renal disease and recent dual transplantation of cadaveric kidneys en bloc presented with increasing abdominal pain and a rising level of serum creatinine. An anterior-view (99m)Tc-mercaptoacetyltriglycine renogram demonstrated the typical overlap of the lower pole of the superior kidney and the upper pole of the inferior kidney. The renogram was consistent with vasomotor nephropathy.

Continuous passive oxygen insufflation results in a similar outcome to positive pressure ventilation in a swine model of out-of-hospital ventricular fibrillation.

Background: The deleterious effects of positive pressure ventilation may be prevented by substituting passive oxygen insufflation during advanced cardiac life support (ACLS) cardiopulmonary resuscitation (CPR).

Methods: We compared 24-h neurologically normal survival among three different ventilation scenarios for ACLS in a realistic swine model of out-of-hospital prolonged ventricular fibrillation (VF) cardiac arrest. No bystander CPR was provided during the first 8 min of untreated VF before the simulated arrival of an emergency medical system (EMS).

Better outcome after pediatric defibrillation dosage than adult dosage in a swine model of pediatric ventricular fibrillation.

Objectives: This study was designed to compare outcome after adult defibrillation dosing versus pediatric dosing in a piglet model of prolonged prehospital ventricular fibrillation (VF).

Background: Weight-based 2 to 4 J/kg monophasic defibrillation dosing is recommended for children in VF, but impractical for automated external defibrillator (AED) use. Present AEDs can only provide adult shock doses or newly developed attenuated adult doses intended for children.

Effect of vasopressin on postresuscitation ventricular function: unknown consequences of the recent Guidelines 2000 for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care.

Objective: To compare the effect on postresuscitation left ventricular function of vasopressin vs. epinephrine used during cardiopulmonary resuscitation in a swine model of prolonged prehospital ventricular fibrillation.

Design: Prospective, randomized experimental study.

Determination of celecoxib in human plasma using solid-phase extraction and high-performance liquid chromatography.

A simple reversed phase high-performance liquid chromatography (HPLC) method was developed for determination of celecoxib levels in human plasma. The procedure involves solid-phase extraction of celecoxib and the internal standard (SC-236) from plasma using C(18) extraction cartridges. The chromatographic separation of celecoxib and SC-236 was achieved with a Nova Pak C(8) column (3.

Contribution of presystemic hepatic extraction to the low oral bioavailability of green tea catechins in rats.

Green tea and green tea catechins have been shown to possess potent cancer-preventive activities in rodent cancer models. At present, epidemiological evidence of the protective effect of green tea consumption against the development of human cancers is not conclusive. Oral bioavailability of green tea catechins has been shown to be low in animals and possibly in humans.
