ABSTRACT
OBJECTIVE: To evaluate whether the quadrivalent human papillomavirus (HPV) (types 6, 11, 16, and 18) vaccine influences the clinical course of juvenile-onset recurrent respiratory papillomatosis (RRP) when administered to a group of patients with this condition. METHODS: Uncontrolled intervention study of patients with juvenile-onset RRP examined at the Pediatric Otorhinolaryngology Clinic, Federal University of São Paulo, where nine patients between the ages of nine and 17 received three doses of the prophylactic quadrivalent HPV vaccine (Gardasil(®)) and were followed for one year. Disease staging, intervals between relapses, intervals between surgeries, and the number of surgeries during the year prior to vaccination and during the first year after vaccination were compared. RESULTS: Eight patients were infected with HPV-6 and one with HPV-11. There were no statistically significant differences in the clinical scores (p=0.083), anatomical scores (p=0.257), intervals between relapses (p=0.062), intervals between surgeries (p=0.357), or the numbers of surgeries (p=0.180) when the years before and after vaccination were compared. All patients had relapses following vaccination. CONCLUSION: Patients with juvenile-onset RRP experienced a similar clinical course in the year after versus the year before vaccination with Gardasil(®).

UNLABELLED: Sleep obstructive breathing disorders are frequent in children but the impact of sleep deprivation on the cognitive learning function is unclear. AIM: To establish whether patients with sleep obstructive breathing disorders show any functional change in learning, memory and attention. MATERIAL AND METHODS: Eighty-one children aged from 6 to 12 years were divided into 3 groups: obstructive sleep apnea syndrome (OSAS), n=24; primary snoring (PS), n=37; and control, n=20. The groups were assessed using learning (Rey) and psychological (Digit, Code, Letter Concealing, and Symbol) tests. RESULTS: OSAS and PS children showed statistically significant worse performance on the variable A1 in Rey test (learning and memory) when compared with controls (p=0.011). PS children had an even worse performance on the variables A2, A4, AT and A6 compared to OSAS participants and controls (p=0.020;p=0.050;p=0.004,p=0.05). CONCLUSION: Children with obstructive sleep breathing disorders, in particular PS, show worse Rey test scores. PS and OSAS children performed similarly in attention tests.
