BACKGROUND/PURPOSE Ovarian pathology, although rare in children, must be included in the differential diagnosis of all girls who present with abdominal pain, an abdominal mass, or precocious puberty. METHODS To improve clinical appreciation of these lesions, the authors reviewed the presentation, evaluation, and outcome of all patients with ovarian(More)
BACKGROUND/PURPOSE Renal tumors are rare in infants less than 6 months of age and may have associated paraneoplastic symptoms. To better define the characteristics of these tumors the authors reviewed their 10-year institutional experience. METHODS The authors searched the pathology database to identify all renal tumors resected at their institution since(More)
BACKGROUND/PURPOSE To better define the indications for peritoneal drainage (PD) in premature babies with intestinal perforation, the authors reviewed their experience with this procedure in a tertiary neonatal intensive care setting. METHODS The charts of all neonates who underwent PD as initial treatment for intestinal perforation between 1996 and 1999(More)
This paper compares the effects on patients of perforation with barium and with air during attempted intussusception reduction by reviewing the clinical, radiological, surgical and pathological findings and sequelae in seven children who received barium and seven who received air. In both groups perforation occurred in infants under 6 months of age (with(More)
Herein we describe a methodology which can be used to evaluate the predictive accuracy of nutritional assessment techniques. We use this methodology to compare seven techniques of nutritional assessment in terms of their ability to predict one nutrition associated hospital complication (infection) by dividing a sample of 59 surgical patients into high risk(More)
Sixty-three patients with splenic injuries were treated during a 5-yr period from 1974-1979. The decision to operate was based on the patient's clinical course, not on the presence of splenic injury alone. Those who were stable on admission or after initial resuscitation were treated nonoperatively. This consisted of strict bed rest, nasogastric suction,(More)
Some authors recommend a routine "protective" antireflux procedure (ARP) in neurologically impaired children undergoing feeding gastrostomy (FG). Over 4 years, we performed FG in 107 neurologically impaired children aged 1 month to 16 years. Ninety-eight had preoperative radiological assessment for gastroesophageal reflux (GER), which was documented in 44,(More)
INTRODUCTION Previously, we demonstrated that 21% of pediatric (<16 years) trauma deaths in the Province of Ontario during the period 1985 to 1987 were potentially preventable. Since then many trauma system changes have occurred including field triage, designation of trauma centers, and improved injury prevention. This study aims to examine the current(More)
OBJECTIVE The objective of this study was to determine the positive and negative clinical predictors of intussusception and the correlation of ultrasonography and air enema in establishing this diagnosis. STUDY DESIGN This was a prospective descriptive cohort study. SETTING This study was performed in a tertiary care pediatric emergency department. (More)
