OBJECTIVE: To determine the relationship between causative factors of sleep-disordered breathing (SDB) and quality of life (QOL) of children who presented with SDB. METHODS: Prospective cross-sectional study was done. Pediatric outpatients with SDB were recruited. Patients with craniofacial, neurologic or syndromic anomalies and previous adenotonsillectomy were excluded. Data collected were clinical history, physical examination and lateral skull X-ray, along with QOL survey by using obstructive sleep apnea-18 (OSA-18) questionnaires. We assessed the association between clinical signs, the size of the tonsils and the adenoids, overweight/obesity and the OSA-18 scores to see the impact of these factors on QOL. RESULTS: Fifty-one children were enrolled. Mean age was 6.4+/-2.6 years. The most common clinical findings was mouth breathing (41.2%). Tonsillar hypertrophy (> or =3+) was found in 62.7 and 52.9% had adenoid-nasopharyngeal ratio greater than 70%. Overweight/obesity were found in 35.3% of the patients. OSA-18 scores ranged from 22 to 85. Tonsillar hypertrophy was significantly related to QOL (p<0.05). Adenoid hypertrophy had trends towards impact on QOL (p=0.094). Mouth breathing correlated well with QOL (p<0.01). Overweight/obesity and QOL had no statistically significant correlation. CONCLUSION: Tonsillar hypertrophy and mouth breathing were the clinical findings that affected most to the QOL of the children with SDB. Adenoid hypertrophy had trends towards the impact on QOL, although not statistically significant.
OBJECTIVE: Human herpesvirus 8 (HHV-8) and Epstein-Barr virus (EBV) are human pathogens associated to a number of neoplasms, including tumors of the Waldeyer's ring. Both viruses have been previously detected by in situ methods in tonsils and adenoids from children. HHV-8 was found in 6.8% of the cases and EBV in about one third of the cases. As they belong to the same gamma-herpesvirus subfamily and share some biological characteristics, it is of medical interest to further explore their possible relationship in the Waldeyer's ring, an issue not yet addressed in the specialized literature. The purpose of the present study is to compare the presence of EBV by in situ hybridization (ISH) in tonsils and adenoids from children up to 14 years of age in cases previously shown to be positive and negative for HHV-8. METHODS: Paraffin wax-embedded sections consisting of 38 tonsils and two adenoids from 40 patients were analyzed. HHV-8 was detected by ISH, using the T1-1 probe for the viral mRNA. EBV was also detected by ISH, using the EBER probe. Both probes and the detection systems were provided by Novocastra. RESULTS: HHV-8 was detected in 19 tonsils and one adenoid. The other 19 tonsils and one adenoid taken from the HHV-8-negative group were selected by pairing age and gender of patients with the HHV-8-positive group. In both groups EBV was detected in 13 cases and was negative in other 7. CONCLUSION: Although both viruses are related in many aspects, some biological and epidemiological features differ. This is reflected in the present results, as EBV is similarly detected in the groups negative and positive for HHV-8, favoring different mechanisms of spread.
OBJECTIVE: The purpose of this study was to determine whether risks of impaired cognitive function could be predicted for children or groups of children with adenotonsillar hypertrophy who were suspected of having obstructive sleep-disordered breathing, from historical and polysomnographic variables used separately or in combination. METHODS: We studied 114 consecutive 6- to 12-year-old children with adenotonsillar hypertrophy, who were referred because of suspected obstructive sleep-disordered breathing, with questionnaires, assessment of tonsil size, general and memory cognitive tests, and attended polysomnography with the use of nasal pressure recording to detect flow. RESULTS: There were important significant relationships between snore group (snored every night versus less often), sleep efficiency, and race and 2 of 3 general cognitive tests (vocabulary and similarities). Significant but weaker relationships were observed between sleep latency and 2 memory indices (verbal memory and general memory) and between sleep efficiency and 2 behavior indices (attention-deficit/hyperactivity disorder summary and hyperactive-impulsive summary). The number of episodes of apnea and hypopnea per 1 hour of sleep predicted the vocabulary score as well as did the snore group, but it did not predict other tests as well as other variables. Tonsil size did not predict any cognitive or behavior score. Confidence intervals for group means were small, whereas prediction intervals for individual children were large. CONCLUSIONS: Risk of impaired cognitive function and behavior can be predicted from snoring history, sleep efficiency, sleep latency, and race but not tonsil size. The combination of snoring history and polysomnographic variables predicted impaired cognitive scores better than did either alone. The snoring history predicted more test scores than the number of episodes of apnea and hypopnea per 1 hour of sleep.
