OBJECTIVE The impact of abnormal feeding behaviors reported for children with autism spectrum disorders (ASDs) on their nutritional status is unknown. We compared nutrient intake from food consumed by children with and without ASD and examined nutrient deficiency and excess. METHODS Prospective 3-day food records and BMI for children (2-11 years) with ASD(More)
OBJECTIVE To report the success rate and complications associated with peripherally inserted central venous catheters (PICCs) and to compare costs between PICCs and centrally inserted central catheters. MATERIAL AND METHODS We undertook a cohort study of the first 1,000 patients referred to the PICC service of a large tertiary-care, university-affiliated,(More)
We report the success rate and complications of peripherally inserted central catheters (PICCs) in patients hospitalized in an intensive care unit (ICU). We performed a cohort study in the ICU of a large tertiary care, university-affiliated community hospital. All ICU patients for whom their attending physicians requested a PICC service consultation were(More)
The study objective of this article was to evaluate percutaneous dilatational tracheostomy (PDT) for emergent airway access. This is a case series of 9 patients who presented over a 58-month period. All patients were in severe respiratory difficulty where intubation by conventional means was unsuccessful. All 9 patients were successfully intubated using PDT(More)
The pharmacokinetics, protein binding, excretion and tissue distribution of 67Ga after the administration of 67Ga-citrate to New Zealand White rabbits is described. Data for 67Ga blood levels were best described by an equation with three exponential components exhibiting half lives of 0.25 h, 7.4 h and 19.5 h, with almost all of the activity in a protein(More)
Cis-platinum, a widely used chemotherapeutic drug, and K2PtCl4, a related complex, were found to inhibit the in vitro protein binding of 67Ga to human transferrin in isolated solution but not to whole serum. Cis-platinum treatment of rabbits resulted in enhanced protein binding and delayed blood clearance of subsequently injected 67Ga-citrate. These effects(More)
The treatment of rabbits with a typical dosage schedule of the chemotherapeutic drug cis-platinum resulted in an increased whole body retention of 67Ga-citrate due to decreased urinary and fecal excretion. The biodistribution of the tracer was also affected with most tissues showing greater accumulation. These changes are primarily related to drug-induced(More)
