Complex dysrhythmias in infants and children.

Dysrhythmias in infants and children are, in many ways, similar to those in adults, yet several important differences exist in their presentation and management. Complex dysrhythmias most frequently encountered in pediatrics include sinus node dysfunction, chaotic atrial rhythm, atrial flutter, supraventricular tachycardia (including Wolff-Parkinson-White syndrome and junctional ectopic tachycardia), complete atrioventricular block (congenital and acquired), and ventricular dysrhythmias (premature ventricular contractions and ventricular tachycardia). Newer approaches to the diagnosis and management of these dysrhythmias are addressed in this paper.

[Subcutaneous analgesic administration].

In March 1989, Saint Luke's Hospital in Montréal piloted the use of continuous and intermittent subcutaneous injection of analgesics. This practice involved patients whose pain could not be relieved by traditional methods of analgesic administration. The article describes the positive results of the project, and clearly identifies suitable patients. It also outlines the advantages, limiting factors and risks involved with each type of infusion. Procedures for set-up and monitoring are briefly explained. The authors conclude that family members of patients can be easily taught to perform the procedure at home.

The effect of exercise-training on resting metabolic rate in lean and moderately obese individuals.

Two experiments have been performed to establish whether exercise-training has an influence on resting metabolic rate (RMR). In a first study, RMR was measured in a cohort of 59 individuals comprising 20 trained and 39 non-trained subjects. The absolute level of RMR in trained subjects exceeded by 11 percent that observed in the non-trained individuals (P less than 0.01). When comparing regression lines of RMR versus FFM between the two groups, the intercept with the Y axis (RMR values) was also significantly higher in trained subjects (P less than 0.01). The second experiment was conducted to find out whether the trend for an elevated RMR noted in athletes could be reproduced in obese persons engaging in an exercise-training program. Eight moderately obese women were submitted to an 11-week training programme, including 5 hours of aerobic exercise per week performed at a mean intensity of about 50 percent VO2 max. The results showed that exercise-training induced a significant rise in RMR which corresponded to 8 percent of pretraining value in kcal/kg FFM/min (P less than 0.01). Thus, data reported here suggest that aerobic exercise-training is associated with an elevated RMR per unit of fat free mass in both lean and moderately obese individuals.

The role of body fat in insulin sensitivity of endurance athletes.

The purpose of the study was to assess the role of adiposity in the enhanced insulin sensitivity observed in endurance athletes (EA). An oral glucose tolerance test (75 g glucose) was administered to nine EA and to 23 sedentary subjects (SS). Two different strategies were used to investigate the problem. First, body composition indicators and Vo2max were correlated with the delta insulin and delta glucose areas measured for 180 minutes following glucose ingestion. These correlation analyses were performed for the two groups combined (n = 32). No significant correlations were observed between either fat weight or percent body fat versus delta insulin, delta glucose or delta glucose/delta insulin areas. Moreover, no significant correlation was observed between the several subcutaneous fat indicators and delta insulin, delta glucose and delta glucose/delta insulin areas. The second strategy consisted of comparing EA to SS when percent body fat difference was eliminated. This was achieved by two different methods, first by covariance analysis and second by comparing subsamples of trained and non-trained subjects paired with respect to percent body fat. These two comparisons revealed that even when adiposity was equal between the groups, a significantly greater insulin sensitivity was observed in the EA group (p less than 0.01). The present results suggest that adiposity is not the determining factor for the increased insulin sensitivity of trained subjects.

Successful treatment of Pseudomonas meningitis and septicemia in a leukemic neutropenic adult.

Pseudomonas aeruginosa is thought to be one of the main species of bacteria producing infection in leukemic patients, especially in those with neutropenia. Although bacteremia is frequent, hematogenous spread causing secondary meningitis is rarely seen. The mortality rate is extremely high. This is believed to be the first report of a successfully treated secondary meningitis caused by Pseudomonas aeruginosa in an adult leukemic patient with a decreased neutrophil count. The patient was treated with intravenous Carbenicillin and gentamicin, and intrathecal gentamicin. The good clinical response was supported by a prompt return of the CSF to normal and by appropriate CSF antimicrobial concentration and bacteriostatic activity.
