Prescribing Practices of Quetiapine for Insomnia at a Tertiary Care Inpatient Child and Adolescent Psychiatry Unit: A Continuous Quality Improvement Project.

Objective: To examine the prescribing practices of quetiapine for insomnia at a tertiary care child and adolescent psychiatric inpatient unit.

Method: A retrospective chart review was conducted on all admissions in 2013 involving night-time only prescription of quetiapine. We examined patient demographics, discharge diagnoses, physician's written indications for prescriptions, and maximum doses used.

Renal handling of beta-2-microglobulin in neonates treated with gentamicin.

Increased levels of urinary beta 2-microglobulin (beta 2M) have been used as a marker of proximal tubular dysfunction in human neonates. To assess the value of beta 2M in the detection of early stages of tubular damage caused by gentamicin, renal handling of beta 2M was studied sequentially in 18 gentamicin-treated neonates with idiopathic respiratory distress syndrome (mean birth weight 1,781 g, mean gestational age 33.7 weeks) during the first 7 days of life.

Maintenance digoxin dosage and steady-state plasma concentration in infants and children.

To define the relationship between digoxin dose and plasma concentration and the changes in body growth, 1181 plasma digoxin levels were measured in 644 infants and children receiving maintenance digoxin therapy. The drug was given intravenously to 166 patients and orally to 478. A significant linear correlation between dose and plasma concentration was observed (r 0.

Quantitative determination of tolazoline in serum and urine.

A high-performance liquid chromatographic procedure is described for the analysis of tolazoline in serum and urine. This assay procedure is suitable for the analysis of micro-samples (50 or 100 microliters serum and 100 microliters urine). Samples are extracted in a single step and injected into a reversed-phase high-performance liquid chromatography system for detection at 210 nm.

Effect of ultrafiltration on peritoneal dialysis drug clearances.

To determine the effect of dialysate osmolarity on peritoneal dialysis drug transfer, peritoneal dialysis clearances of theophylline, phenobarbital, and tobramycin were determined in 10 rabbits using dialysate containing 1.5 and 4.25% glucose.
