OBJECTIVES To assess the prevalence of neurologic and neuropsychological symptoms in the short-term and 1 year after an electric shock and to explore whether any of these were associated with risk factors. METHODS Patients presenting to one of 21 EDs between October 2000 and November 2004 were eligible to be enrolled in a prospective observational study(More)
The recent marketing of slow release preparations of theophylline and new indications for the use of the drug have resulted in a marked increase in the sale of theophylline products. This phenomenon combined with the drug's highly variable pharmacokinetics has led to an increase in the number of theophylline intoxications. The morbidity and mortality rates(More)
The accuracy of signs and symptoms as predictors of the presence and severity of esophageal injury was evaluated in 378 children admitted to three pediatric hospitals between 1970 and 1980. The signs and symptoms analyzed included nausea, vomiting, dysphagia, refusal to drink, abdominal pain, increased salivation, oropharyngeal burns, and abdominal(More)
STUDY OBJECTIVE Because death has occurred with injury involving voltage as low as 50 to 60 V (probably the result of arrhythmias), we wanted to evaluate the necessity of cardiac monitoring in children sustaining electrical injuries with 120 or 240 V. DESIGN The charts of 151 children who presented to the emergency department between April 1, 1989, and(More)
OBJECTIVES To summarize and compare different prognostic criteria used to determine need for liver transplantation in patients with fulminant hepatic failure secondary to acetaminophen poisoning. DATA SOURCES Studies published in the literature that investigated criteria for hepatic transplantation secondary to acetaminophen-induced liver failure as(More)
A fourth molecular from of alpha-galactosidase, designated L(IV), an alkaline alpha-galactosidase, was isolated from leaves of Cucurbita pepo and purified 165-fold. It was active over a narrow pH range with optimal hydrolysis of p-nitrophenyl-alpha-d-galactoside and stachyose at pH 7.5. The rate of stachyose hydrolysis was 10 times that of raffinose. K(m)(More)
OBJECTIVE To identify risk factors of fatal arrhythmia following electrical shock, by comparing the prevalence of transthoracic current, tetany, decreased skin resistance because of wet extremities, skin burns and heart disease in victims of electrocution with instant as opposed to delayed death. DESIGN Retrospective case-control study, based on the(More)
OBJECTIVE To report our experience monitoring patients with previously identified theoretical risk factors of significant electrical injury. METHODS Patients who presented to one of 21 emergency departments between October 2000 and November 2004 were eligible to be enrolled in a prospective observational cohort study if after an electric shock they had(More)
We conducted a prospective randomized study to evaluate the efficacy of a single daily dose of 4 mg/kg of trimethoprim coupled with 17.5 mg/kg of sulphadiazine for three (group 1) or 10 days (group 2) in the treatment of uncomplicated urinary tract infections in children. Forty patients (nine boys and 31 girls) aged 2.5-18 years, presenting with a urinary(More)
