OBJECTIVE: To evaluate the efficacy of adenoidectomy compared with long term chemoprophylaxis and placebo in the prevention of recurrent acute otitis media in children aged between 10 months and 2 years. DESIGN: Randomised, double blind, controlled trial. SETTING: Oulu University Hospital, a tertiary centre in Finland. PARTICIPANTS: 180 children aged 10 months to 2 years with recurrent acute otitis media. INTERVENTION: Adenoidectomy, sulfafurazole (sulphisoxazole) 50 mg/kg body weight, given once a day for six months or placebo. Follow up lasted for two years, during which time all symptoms and episodes of acute otitis media were recorded. MAIN OUTCOME MEASURES: Intervention failure (two episodes in two months or three in six months or persistent effusion) during follow up, number of episodes of acute otitis media, number of visits to a doctor because of any infection, and antibiotic prescriptions Number of prescriptions, and days with symptoms of respiratory infection. RESULTS: Compared with placebo, interventions failed during both the first six months and the rest of the follow up period of 24 months similarly in the adenoidectomy and chemoprophylaxis groups (at six months the differences in risk were 10% (95% confidence interval -9% to 29%) and 18% (-2% to 38%), respectively). No significant differences were observed between the groups in the numbers of episodes of acute otitis media, visits to a doctor, antibiotic prescriptions, and days with symptoms of respiratory infection. CONCLUSIONS: Adenoidectomy, as the first surgical treatment of children aged 10 to 24 months with recurrent acute otitis media, is not effective in preventing further episodes. It cannot be recommended as the primary method of prophylaxis.
STUDY OBJECTIVES: In sleep-disordered breathing (SDB), visual or computerized analysis of electroencephalogram (EEG) signals shows that disruption of sleep architecture occurs in association with apneas and hypopneas. We developed a new signal analysis algorithm to investigate whether brief changes in cortical activity can also occur with individual respiratory cycles. DESIGN: Retrospective. SETTING: University sleep laboratory. PARTICIPANTS: A 6 year-old boy with SDB. INTERVENTION: Polysomnography before and after clinically indicated adenotonsillectomy. MEASUREMENTS: For the first 3 hours of nocturnal sleep, a computer algorithm divided nonapneic respiratory cycles into 4 segments and, for each, computed mean EEG powers within delta, theta, alpha, sigma, and beta frequency ranges. Differences between segment-specific EEG powers were tested by analysis of variance. Respiratory cycle-related EEG changes (RCREC) were quantified. RESULTS: Preoperative RCREC were statistically significant in delta (P < .0001), theta (P < .001), and sigma (P < .0001) but not alpha or beta (P > .01) ranges. One year after the operation, RCREC in all ranges showed statistical significance (P < .01), but delta, theta, and sigma RCREC had decreased, whereas alpha and beta RCREC had increased. Preoperative RCREC also were demonstrated in a sequence of 101 breaths that contained no apneas or hypopneas (P < .0001). Several tested variations in the signal-analysis approach, including analysis of the entire nocturnal polysomnogram, did not meaningfully improve the significance of RCREC. CONCLUSIONS: In this child with SDB, the EEG varied with respiratory cycles to a quantifiable extent that changed after adenotonsillectomy. We speculate that RCREC may reflect brief but extremely numerous microarousals.
STUDY OBJECTIVE: To prospectively evaluate the outcome of surgical treatment decisions made by a multidisciplinary team for children aged 18 months to 12 years with sleep-disordered breathing (SDB). DESIGN AND SETTING: A multidisciplinary team evaluated children referred to a sleep clinic for suspicion of SDB using polysomnography, questionnaires, and clinical evaluations. Suggestions for treatment (surgical, medical, or orthodontic) were made and sent to referring providers. A follow-up evaluation, which included a repeat of all of the tests performed at baseline, was performed 3 months after treatment (and at 6 months for a subgroup of subjects). The clinical outcome of the recommended versus the performed treatment was compared. PATIENTS: 56 successively evaluated children. RESULTS: Based on insurance plans, 11 children were treated by a surgeon on the multidisciplinary team, who followed all treatment recommendations. After treatment, 1 of the 11 children still had SDB. Forty-five children were referred to other specialists. Only 1 of these children had the team's treatment recommendations implemented. Twenty-six of the 45 children had residual symptoms. Twelve children had polysomnographic abnormalities with or without symptoms or snoring. Sixteen children (28.6%) underwent a second surgical procedure. CONCLUSION: There are misconceptions in the pediatric and otolaryngologic communities about the rationale for the surgical treatment of SDB. Interactions between mouth breathing, maxillofacial growth, and clinical symptoms associated with SDB are not well understood. Multidisciplinary evaluations of the anatomic abnormalities of children with SDB lead to better overall treatment.
