Severe hypoglycemia in IDDM children.

Abstract: The incidence of severe hypoglycemia was determined in a 1-yr prospective study of 350 insulin-dependent diabetic (IDDM) children. There were no significant differences in mean glycosylated hemoglobin, age, and duration of disease between the patients who had severe hypoglycemia and those who did not. There were 25 episodes in 24 patients (6.8%). Their insulin doses at the time of the episode (U.kg-1.day-1) were significantly higher than those of the nonhypoglycemic group (mean +/- SD 1.01 +/- 0.30 vs. 0.89 +/- 0.29; P = .04). The hypoglycemic group had a significantly higher mean number of previous episodes of severe hypoglycemia than the nonhypoglycemic group (0.92 +/- 1.18 vs. 0.25 +/- 0.68; P = .01). In only 64% of the episodes, an unusual circumstance such as strenuous physical activity or missed or delayed meals preceded the event. Multivariate analysis of the data by logistic regression showed risks of developing hypoglycemia of 2.5 per 0.5 U/day insulin and of 2.0 per previous episode of severe hypoglycemia. We conclude that severe hypoglycemia may be a recurrent problem in some diabetic children, but it does not appear to be related to age or blood glucose control. The presence of previous episodes may be a guide to identify patients at greater risk of developing severe hypoglycemia. Adherence to regular testing, strict spacing and consistency of meals, and extra food for extra activity may reduce this serious complication.

Student Outcomes in Inquiry Instruction: A Literature-Derived Inventory.

Abstract: Curricular reform efforts are underway in many countries, focused on adopting inquiry-based approaches to teaching and learning. Therefore, it is increasingly important to understand what outcomes students attain in inquiry environments. Derived from a literature review, a 23-item, criterion-referenced inventory is presented for theoretically implied and empirically based outcomes or benefits for students engaging in inquiry, and includes research on overlapping pedagogical topics such as discovery learning and problem-based learning. Student outcomes include knowledge and skills, intrinsic motivation, and development of expertise, among others. Supporting research is primarily available in the areas of cognitive and affective outcomes (e.g., knowledge, skills, motivation, attitudes, and creativity). This list can be used as a starting point for research or converted into professional development tools.

Post-tonsillectomy and adenoidectomy hemorrhage.

Abstract: This is a retrospective review of 6842 tonsillectomies and adenoidectomies performed over a seven-year period at the Montreal Children's Hospital. The total incidence of postoperative bleeding was 2.5%. The incidence of primary post-tonsillectomy hemorrhage was 1.0%, with 78% of these children having developed bleeding within 12 hours of surgery. The overall incidence of secondary post-tonsillectomy hemorrhage was 1.2%. Twenty-nine percent of children with primary hemorrhage required a second general anesthetic, and 40% required blood component transfusion. Eight percent of children with secondary hemorrhage required a second general anesthetic and 24% received transfusions. Based on these findings, primary and secondary hemorrhage can be classified further into major and minor. The criteria for a major post-tonsillectomy hemorrhage are: requirements of a general anesthetic to control and repair the bleeding, or blood loss that is sufficient to require blood component transfusion therapy. The relevance of these findings with regard to outpatient adenotonsillectomies is discussed.
