BACKGROUND AND OBJECTIVES The utility of on-line evidence-based summary databases for answering clinical questions at the point of care is not well understood. Our objectives were to determine if family physician faculty could answer their questions using on-line resources and the proportion of answers that influenced patient care. METHODS This was a(More)
Commercial serologic assays accurately detect adult Helicobacter pylori infection. Their use in children remains controversial. An ELISA to detect H. pylori IgG in children was developed and compared with three commercial assays. ELISA standardization was done with sera from all ages and validation was done with another cohort of sera with known H. pylori(More)
BACKGROUND Alpha-fetoprotein (AFP) is a glycoprotein molecule, which has similarity to albumin and is produced by the fetal liver. Its biological role is unclear and factors that may influence its concentrations in neonates are only partially identified. However, it has an important role as a diagnostic marker, especially in certain tumors and liver(More)
The effectiveness of unconjugated estriol (uE3) as a serum marker for the detection of Down syndrome (DS) during the 2nd trimester of pregnancy was evaluated. A population of 18,764 normal singleton pregnancies was screened for alpha-feto-protein and human chorionic gonadotropin. In 9,311 women, uE3 was added. Using a risk of 1:250 at term as a cutoff(More)
BACKGROUND Patients with early Thrombolysis in Myocardial Infarction (TIMI) grade 2 flow after thrombolysis appear to have outcomes similar to thrombolytic failures. To evaluate the origin and evolution of early TIMI 2 flow, we examined early and late angiographic and ventriculographic data from the Global Utilization of Streptokinase and TPA for Occluded(More)
Cramping abdominal pain with intermittent intestinal obstruction finally prompted investigation in a 4 1/2-year-old boy with severe failure to thrive (FTT). An entero-enteric intussusception was corrected, and celiac disease was identified as the cause of his inanition. Concomitant FTT and cramping abdominal pain should prompt investigation for celiac(More)
BACKGROUND The prevalence of Helicobacter pylori infection and its role in gastroduodenal disease in cystic fibrosis (CF) are controversial. Additionally, serologic determination of infection in this population may be inaccurate because of cross-reactivity with other bacterial species. The seroprevalence of H. pylori in a cohort of patients with CF and its(More)
Our aim was to test whether alpha fetoprotein (AFP) might serve as a marker of hepatic immaturity sufficient to predict an increased risk for neonatal hyperbilirubinemia (NHB) in term babies. We checked umbilical cord AFP (UC AFP) levels in 174 healthy full-term infants (male/female ratio 1.26:1) at birth. Bilirubin levels were measured upon discharge from(More)
Calciphylaxis is a lethal disorder seen in patients with end-stage renal disease and is characterized by painful necrotic skin lesions. The pathophysiology is still unknown. Elevated calcium, phosphorous and parathormone appear to play a role in causing small and medium sized vasculopathy. Diagnosis is delayed, prognosis is poor and mortality remains high.(More)
