Zoledronic Acid vs Placebo in Pediatric Glucocorticoid-induced Osteoporosis: A Randomized, Double-blind, Phase 3 Trial.

Context: Glucocorticoids (GCs) prescribed for chronic pediatric illnesses are associated with osteoporotic fractures.

Objective: This study aims to determine the efficacy and safety of intravenous (IV) zoledronic acid (ZA) compared with placebo to treat pediatric GC-induced osteoporosis (GIO).

Methods: Children aged 5 to 17 years with GIO were enrolled in this multinational, randomized, double-blind, placebo-controlled phase 3 trial (ClinicalTrials.

Automated segmentation of villi in histopathology images of placenta.

Purpose: Manual analysis of clinical placenta pathology samples under the microscope is a costly and time-consuming task. Computer-aided diagnosis might offer a means to obtain fast and reliable results and also substantially reduce inter- and intra-rater variability. Here, we present a fully automated segmentation method that is capable of distinguishing the complex histological features of the human placenta (i.

Anterior segment infiltration of acute lymphoblastic leukemia: case report and systematic review.

Acute lymphoblastic leukemia (ALL) relapse implies a poor prognosis and demands emergency treatment. Leukemic infiltration of the anterior segment can masquerade as intraocular inflammation; a high index of suspicion for this complication is essential. We describe a case of ocular relapse in a 2-year-old male on maintenance therapy for ALL.

The diagnosis of concussion in a pediatric emergency department.

Objectives: To compare the proportion of children diagnosed with a concussion by pediatric emergency physicians vs the proportion who met criteria for this injury as recommended by Zurich Fourth International Conference on Concussion consensus statement and to determine clinical variables associated with a physician diagnosis of a concussion.

Study Design: This was a prospective, cross-sectional study conducted at a tertiary care pediatric emergency department. We enrolled children ages 5 through 17 who presented with a head injury and collected data on demographics, mechanism of injury, head injury-related symptoms/signs, physician diagnosis, and discharge advice.

Knowledge of genetic testing for hereditary kidney cancer in Canada is lacking: The results of the Canadian national hereditary kidney cancer needs assessment survey.

Introducton: Treatment of hereditary renal cell carcinoma (HRCC) requires a multidisciplinary approach that may involve medical oncologists, geneticists, genetic counsellors, and urologists. The objective of our survey was to obtain current and representative information about the use and perceived importance of genetic testing for HRCC in Canada.

Methods: A self-administered web-based survey was provided to Canadian medical oncologists, geneticists, genetic counsellors, and urologists in collaboration with their respective associations.

Respiratory disease in Canadian First Nations and Inuit children.

First Nations and Inuit Children are disproportionately affected by respiratory infections such as viral bronchiolitis, pneumonia and tuberculosis. Rates of long-term lung disease following severe respiratory infections early in life, such as bronchiectasis, are also elevated. In contrast, rates of asthma may be somewhat less than in other Canadian children, although rates of poor asthma control are increased.

Prevalence and correlates of folic acid supplement use in Canada.

Dietary supplements are an important source of folic acid, a nutrient that is vital in reducing the risk of neural tube defects. As part of the 2007 to 2009 Canadian Health Measures Survey, data were collected on supplement use, and biomarkers were directly measured. Use of supplements that contain folic acid was reported by 25% of Canadians aged 6 to 79.

Endoscopic treatment of vesicoureteric reflux with Deflux: a Canadian experience.

Introduction: Vesicoureteric reflux is a common problem encountered in urological practice. Traditionally, if medical management with low-dose antibiotic prophylaxis failed, the only alternative was ureteroneocystostomy. Recently, promising results with subureteric injection of dextranomer/hyaluronic acid copolymer (Deflux) have renewed interest in the endoscopic treatment of vesicoureteric reflux (VUR).

Adrenal function in pediatric critical illness.

OBJECTIVES: Adrenal dysfunction has been documented in critically ill adult populations and in children with septic shock and may have serious consequences if undiagnosed. However, there is no information available on adrenal function in critically ill children with various underlying conditions. DESIGN: A prospective, descriptive study was carried out to investigate the occurrence of adrenal dysfunction in pediatric critical illness.

Factors influencing childhood influenza immunization.

Following the launch of a publicly funded influenza immunization program for all residents of Ontario over the age of 6 months, we evaluated 203 parents of children who presented to our emergency department between January and March of the following year (2001). Overall, 54 (27%) of the children had been vaccinated. Parents of non-immunized children were more likely to believe that immunization resulted in a flu-like illness (42% v.
