This study examined two strategies for increasing the accuracy with which general education teachers implemented a peer tutoring intervention for reading comprehension. The intervention was implemented for 5 elementary school students who had been referred for consultation services. Initial implementation of the intervention by the teachers was variable,(More)
We undertook a prospective, controlled study to evaluate the effect of trimethoprim-sulfamethoxazole in children with proven Escherichia coli O157:H7 enteritis on the duration fo symptoms, on fecal excretion of pathogen, and on the risk of progression to hemolytic-uremic syndrome. There was no statistically significant effect of treatment on progression of(More)
A prospective study was performed to estimate the frequency of gastroenteritis due to Yersinia enterocolitica in Montreal children and their families. Evidence of bacterial infection was correlated with clinical features and serologic responses. YE was isolated from the stools of 181 (index cases) of 6,364 children with gastroenteritis over a 15-month(More)
The emergence of rapid, user-friendly, point-of-care (POC) diagnostic systems is paving the way for better disease diagnosis and control. Lately, there has been a strong emphasis on developing molecular-based diagnostics due to their potential for greatly increased sensitivity and specificity. One of the most critical steps in developing practical(More)
This study examined the effects of reinforcement contingencies designed to increase the performance of existing reading skills as well as the effects of instruction--modeling and practice--designed to increase skill level for oral reading fluency across three levels of reading materials. Results showed that a combination of contingencies, modeling, and(More)
Sixty-five strains of Yersinia enterocolitica were isolated from stool specimens obtained from 35 patients over a 12-month period. The microbiologic characteristics and drug sensitivities are reported and the clinical patterns of disease associated with the organism are described. Gastroenteritis affecting infants and young children is the most frequent(More)
Stool specimens from children with gastroenteritis and their household contacts were cultured for Yersinia enterocolitica by direct plating onto routine laboratory media. These stools were also inoculated into phosphate-buffered saline and subcultured to the same media after 1 day or 3 weeks of incubation at 4 degrees C. Y. enterocolitica was isolated from(More)
The development of cutaneous cryptococcosis is extremely rare in the human immunodeficiency virus-negative population. The cutaneous manifestations vary greatly, with the rarest presenting as cellulitis. We report a unique case of a 64-year-old woman who had been on prednisone monotherapy for the treatment of myasthenia gravis and subsequently developed(More)
From 1973 to 1976, a total of 146 strains of Yersinia enterocolitica was isolated from children at the Ste. Justine Hospital and Montreal Children's Hospital. All strains tested were of serotype 0:3, biotype 4. The majority (80%) of children from whom Y. enterocolitica was isolated were under 5 years of age and in 74 of 93 cases reviewed diarrhea was the(More)
