RESUMO

INTRODUCTION: Obstructive sleep apnea is highly prevalent in non-syndromic Pierre Robin sequence patients. Studies have found a probable relationship between obstructive sleep apnea and nasal obstruction and between obstructive sleep apnea and enuresis. Assessment of the relationship between these variables in non-syndromic Pierre Robin sequence patients is scarce. OBJECTIVE: The present study aims to evaluate the relationship between symptoms of obstructive sleep apnea, nasal obstruction and enuresis, determining the prevalence of symptoms suggestive of these conditions, in schoolchildren with non-syndromic Pierre Robin sequence, and describe the prevalence of excessive daytime sleepiness habitual snoring and voiding dysfunction symptoms associated with enuresis. METHODS: This was a prospective analytical cross-sectional study developed at a reference center. Anthropometric measurements and a structured clinical interview were carried out in a sample of 48 patients. The instruments "sleep disorders scale in children" "nasal congestion index questionnaire" (CQ-5), and the "voiding dysfunction symptom score questionnaire" were used. Statistical analysis was performed for p < 0.05. RESULTS: Positive "sleep disorders scale in children" scores for obstructive sleep apnea and CQ-5 for nasal obstruction were observed in 38.78% and 16.33%, respectively. Enuresis was reported in 16.33% of children, being characterized as primary in 71.43% and polysymptomatic in 55.55%; according to the "voiding dysfunction symptom score questionnaire". There was a significant relationship between nasal obstruction and obstructive sleep apnea symptoms (p < 0.05), but no significance was found between obstructive sleep apnea symptoms and enuresis, and between nasal obstruction and enuresis. The prevalence of excessive daytime sleepiness was 12.24% and of habitual snoring, 48.98%. A family history of enuresis, younger age in years and a positive "voiding dysfunction symptom score questionnaire" score were associated with a higher prevalence of enuresis (p < 0.05). CONCLUSION: Children with non-syndromic Pierre Robin sequence are at high risk for obstructive sleep apnea symptoms and habitual snoring, with a correlation being observed between nasal obstruction and obstructive sleep apnea symptoms. In addition, the study showed that non-syndromic Pierre Robin sequence, obstructive sleep apnea and nasal obstruction symptoms were not risk factors for enuresis in these patients.

Resumo Introdução A apneia obstrutiva do sono apresenta elevada prevalência na população com sequência de Pierre Robin não sindrômica. Estudos constataram provável relação entre apneia obstrutiva do sono e obstrução nasal e entre apneia obstrutiva do sono e enurese, é escassa a avaliação da relação entre essas variáveis na sequência de Pierre Robin não sindrômica. Objetivo Avaliar a relação entre sintomas de apneia obstrutiva do sono, obstrução nasal e enurese, determinar a prevalência de sintomas sugestivos dessas condições, em crianças em idade escolar com sequência de Pierre Robin não sindrômica, assim como descrever a prevalência de sonolência excessiva diurna, ronco habitual e sintomas de disfunção miccional associados à enurese. Método Estudo prospectivo transversal analítico desenvolvido em centro de referência. Fez‐se aferição antropométrica e entrevista clínica estruturada em amostra de 48 pacientes. Os instrumentos usados foram: "escala de distúrbios do sono em crianças", questionário "índice de congestão nasal" (CQ‐5) e questionário "sistema de escore de disfunção miccional". A análise estatística foi feita para p < 0,05. Resultados Escores positivos da "escala de distúrbios do sono em crianças" para apneia obstrutiva do sono e do CQ‐5 para obstrução nasal foram observados em 38,78% e 16,33%; respectivamente. Enurese foi relatada em 16,33% das crianças e foi caracterizada como primária em 71,43% e polissintomática em 55,55%; conforme "sistema de escore de disfunção miccional". Observou‐se relação significante entre obstrução nasal e sintomas de apneia obstrutiva do sono (p < 0,05), porém não significante entre sintomas de apneia obstrutiva do sono e enurese, e obstrução nasal e enurese. A prevalência de sonolência excessiva diurna foi de 12,24% e de ronco habitual, de 48,98%. História familiar de enurese, menor idade em anos e escore positivo na "sistema de escore de disfunção miccional" foram associados a maior prevalência de enurese (p < 0,05). Conclusão Crianças com sequência de Pierre Robin não sindrômica estão sob alto risco para sintomas de apneia obstrutiva do sono e ronco habitual, foi observada correlação entre obstrução nasal e sintomas de apneia obstrutiva do sono. Demonstrou‐se, também, que sequência de Pierre Robin não sindrômica, sintomas de apneia obstrutiva do sono e obstrução nasal não constituíram fator de risco para enurese na população estudada.

RESUMO

OBJECTIVE: To estimate the prevalence of symptoms of obstructive sleep apnea (OSA), nasal obstruction, and enuresis in children with nonsyndromic unilateral cleft lip and palate. DESIGN: Prospective cross-sectional study. SETTING: Referral care center. PARTICIPANTS: One hundred seventy-four children aged 6 to 12 years of both genders. INTERVENTIONS: Symptoms of OSA and nasal obstruction were investigated by analysis of scores obtained by the Sleep Disturbance Scale for Children (SDSC) and Congestion Quantifier (CQ-5). Enuresis was considered as present when urinary loss was reported during sleep (at least 1 episode/month, last 3 months). To characterize the enuresis as mono- or polysymptomatic, symptoms of dysfunction of the lower urinary tract (DLUT) were investigated by the Dysfunctional Voiding Scoring System (DVSS). Statistical analysis was performed at a 5% level of significance. RESULTS: Positive SDSC scores for OSA were observed in 60 (34%) children; positive CQ-5 scores for nasal obstruction in 45 (26%), positive DVSS scores for DLUT in 30 (17%), and enuresis was reported by 29 (17%), being categorized as primary in 66% and polysymptomatic in 72% of the children. Compared to the pediatric population, OSA, nasal obstruction, and enuresis prevalence ratios were up to 7 (95% confidence interval [CI] 5-9), 2 (95% CI 2-3), and 3 times (95% CI 2-5) higher, respectively. There was a positive/moderate correlation between symptoms of OSA and nasal obstruction ( P = .0001). No correlation was seen between symptoms of OSA and enuresis. CONCLUSIONS: Children with nonsyndromic cleft lip and palate have high prevalence of nasal obstruction and enuresis and are at risk of OSA.
