Comparison of albuterol delivered by a metered dose inhaler with spacer versus a nebulizer in children with mild acute asthma.

OBJECTIVE: In children with mild acute asthma, to compare treatment with a single dose of albuterol delivered by a metered dose inhaler (MDI) with a spacer in either a weight-adjusted high dose or a standard low-dose regimen with delivery by a nebulizer. STUDY DESIGN: In this randomized double-blind trial set in an emergency department, 90 children between 5 and 17 years of age with a baseline forced expiratory volume in 1 second (FEV1 ) between 50% and 79% of predicted value were treated with a single dose of albuterol, either 6 to 10 puffs (n = 30) or 2 puffs (n = 30) with an MDI with spacer or 0.15 mg/kg with a nebulizer (n = 30). RESULTS: No significant differences were seen between treatment groups in the degree of improvement in percent predicted FEV1 (P =.12), clinical score, respiratory rate, or O2 saturation. However, the nebulizer group had a significantly greater change in heart rate (P =.0001). Our study had 93% power to detect a mean difference in percent predicted FEV1 of 8 between the treatment groups. CONCLUSION: In children with mild acute asthma, treatment with 2 puffs of albuterol by an MDI with spacer is just as clinically beneficial as treatment with higher doses delivered by an MDI or by a nebulizer.

A randomized controlled trial of penicillin vs clindamycin for the treatment of aspiration pneumonia in children.

OBJECTIVE: To compare the effectiveness of intravenous penicillin vs clindamycin for the treatment of aspiration pneumonia. DESIGN: A double-blind, randomized controlled trial. SETTING: A tertiary care pediatric hospital. PATIENTS: We enrolled 42 children, aged 6 months to 18 years, who were admitted to the hospital for the treatment of aspiration pneumonia. All of the children had underlying conditions that predispose to aspiration. INTERVENTION: The patients were randomly assigned to receive intravenous penicillin G sodium, 250,000 U/kg every 24 hours, or intravenous clindamycin phosphate, 30 mg/kg every 24 hours. MAIN OUTCOME MEASURE: The primary outcome measure was "time to ready for discharge" from the hospital. RESULTS: In an effectiveness (intention to treat) analysis, the median time (interquartile range) to ready for discharge from the hospital was 4.9 days (range, 2.8-6.5 days) in the penicillin-treated group and 3.4 days (range, 2.3-6.8 days) in the clindamycin-treated group (P = .66). Results were not markedly altered when adjusted for the age difference of the groups or in the efficacy analysis (after the exclusion of 9 patients who withdrew from the trial). Rates for readmission to the hospital were similar in the 2 groups. CONCLUSION: Penicillin and clindamycin seem to be equally effective for the treatment of aspiration pneumonia in children hospitalized for this illness.

Do child and/or parent bereavement programs work?

Bereavement programs for children and parents are becoming popular since there are more and more neonatal intensive care programs, pediatric oncology programs and pediatric intensive care programs offering these services. This paper addresses the following question: Do bereavement programs work? An overview of the literature dating back to 1964 was undertaken. Only papers dealing with treatment were reviewed. Randomized controlled trials were selected as presenting the best evidence for or against program effectiveness. Methodologic features such as description of the sample, comparability of treatment and control groups, description of the intervention, use of objective, valid, reproducible and blinded outcome measures, sample size calculations, thoroughness of follow-up and attention to clinical as well as statistical significance were assessed. Four randomized controlled trials were found in the literature search. Two of the studies showed benefit, two did not. All four suffered significant methodologic flaws. At this time it is unclear as to whether or not bereavement programs help families. Given the high costs of health care, it is important that studies be done to determine which families are likely to benefit from bereavement programs and what type of program is effective.

Influenza vaccination of high-risk children: a survey of three physician groups.

OBJECTIVE: To determine the variability in physician knowledge, attitudes, and behaviours in relation to influenza vaccination of children. METHOD: A 17-item cross-sectional questionnaire, with follow-up mailings to non-responders, was mailed to a random sample of 100 family physicians and 100 community pediatricians within Metropolitan Toronto and all 130 subspecialists at The Hospital for Sick Children, Toronto. RESULTS: Of 315 eligible physicians, 243 (77%) responded. Of the three groups, community pediatricians were more likely than either family physicians or subspecialists, to recommend vaccination for all but one of the high-risk conditions. Pediatricians (54%) were also the most likely to use active strategies to contact families of high-risk children compared with family physicians and subspecialists (both 23%). Only 44% of all physicians were themselves vaccinated against influenza. CONCLUSIONS: Influenza vaccination is recommended by most physicians; however, the responsibility for vaccination appears to fall to those in the community. Physician education plus further research and a review of provincial strategies for improving vaccination are needed.
