RESUMO

ABSTRACT Sleep-disordered breathing (SDB) is a group of disorders associated with breathing anomalies during sleep. Easily detectable by sound, snoring is one of the most common manifestations and the main sign of SDB. Snoring is characteristic of breathing sound during sleep, without apnea, hypoventilation, or interrupted sleep. It may reduce the percentage of sleep and increase microarousals due to breathing effort or gas exchange. A range of questionnaires have been validated and adapted to the pediatric population to screen for patients who require laboratory testing. The Pediatric Sleep Questionnaire (PSQ) screens for SDB and identifies primary signs such as snoring. RoncoLab is a mobile application that records and measures snoring intensity and frequency Aim To compare the RoncoLab app and the PSQ regarding how efficiently they diagnose snoring Materials and Method This was an observational, analytical study of 31 children aged 7 to 11 years who visited the pediatric dental clinic at Benemérita Universidad Autónoma de Puebla, Mexico (BUAP). The PSQ was applied to diagnose SDB. Guardians were then instructed on how to download and use the mobile application to record data while the child was sleeping at home. Agreement between RoncoLab and the PSQ was analyzed statistically by Cohen's Kappa index at 95% confidence level Results The Kappa index for identification of primary snoring was 0.743 (p<0.05). App sensitivity was 0.92, and specificity 0.82 Conclusion There is good agreement between PSQ and RoncoLab for diagnosing primary snoring, with acceptable sensitivity and specificity.

RESUMEN Los trastornos respiratorios del sueño (TRS) son un grupo de padecimientos asociados con anormalidades respiratorias del sueño. Una de las manifestaciones más comunes es el ronquido; signo fácil de detectar por el ruido que emite y se considera como el signo principal. Este trastorno es característico del ruido respiratorio durante el sueño, sin apneas, hipoventilación, ni interrupciones del sueño. Este puede ocasionar disminución del porcentaje del sueño y aumentar los microdespertares, esto debido al esfuerzo respiratorio o al intercambio de gases. En la actualidad existen cuestionarios validados y adaptados para la población pediátrica útiles como herramienta clínica para el tamizaje y selección de pacientes que requieran pruebas de laboratorio. El Pediatric Sleep Questionnaire (PSQ) permite el cribado de TRS e identificación de signos primarios como el ronquido. RoncoLab es una aplicación móvil que registra y mide la intensidad y frecuencia del ronquido. Objetivo Comparar la eficacia del diagnóstico del ronquido por medio del RoncoLab contrastado con el PSQ Materiales y Método Estudio observacional, analítico, en el cual se incluyeron 31 niños de 7 a 11 años, que acudieron a la clínica de odontopediatría de la Benemérita Universidad Autónoma de Puebla, México (BUAP) Se aplicó el PSQ a los 31 niños para el diagnóstico de TRS, después se le instruyó al tutor como descargar y utilizar la aplicación móvil para registrar los datos obtenidos en las horas de sueño en casa. El análisis estadístico de concordancia entre los instrumentos diagnósticos se realizó con el Índice Kappa de Cohen a un nivel de confianza del 95% Resultados El Índice de Kappa para la identificación de los ronquidos primarios fue de 0.743 (p<0.05).

Material e Método: Trata-se de estudo observacional, analítico e transversal, realizado com 30 indivíduos adultos com queixa de ronco durante o sono, com idade média de 45 anos e 5 meses. Para a avaliação de motricidade oromiofuncional foi utilizado o protocolo AMIOFE. Foram aplicados questionários para investigação do ronco e qualidade de sono dos participantes: Questionário de Berlin, Escala de Sonolência de Epworth e Questionário de qualidade de sono de Pittsburgh. Resultados: Os resultados do questionário de Pittsburgh indicaram disfunção na qualidade do sono em 66,67% dos participantes. A sonolência diurna foi evidenciada em 33,33%, por meio da Escala de Epworth. 60% dos participantes apresentaram alto risco para AOS, por meio dos escores obtidos no instrumento de Berlin. Indivíduos que não praticam exercício físico e com posição habitual de língua no assoalho bucal apresentaram maiores escores no questionário de Berlin. Houve correlação positiva estatisticamente significante e moderada entre as variáveis Índice de massa corporal (IMC) e os escores do Questionário de Berlin. Conclusão: Indivíduos com queixa de ronco apresentam dificuldades relacionadas à qualidade do sono. A autopercepção negativa de qualidade do sono teve relação com dados de motricidade orofacial, hábitos alimentares, composição corporal e hábitos de estilo de vida. (AU)

Introduction: Sleep is a vital and essential function for human survival and aims to promote bodily and mental repair. Objective: To investigate factors associated with self-perception of sleep quality, as well as possible alterations in orofacial structures and stomatognathic functions in individuals with snoring complaints. Material and Method: Observational, analytical and cross-sectional study, conducted with 30 adult individuals complaining of snoring during sleep, with a mean age of 45 years and 5 months. For the evaluation of orofacial myofunctional motricity, the (AMIOFE) was used. Questionnaires were applied to investigate the snoring and sleep quality of the participants: Berlin Questionnaire, Epworth Sleepiness Scale and Pittsburg Sleep Quality Index Questionnaire. Results: The Pittsburgh questionnaire results indicated sleep quality dysfunction in 66.67% of participants. Daytime sleepiness was evidenced in 33.33%, using the Epworth Scale. 60% of the participants presented high risk for obstructive sleep apnea syndrome (OSA), through the scores obtained in the Berlin questionnaire. Individuals who do not practice physical exercise and with usual tongue position on the oral floor presented higher scores in the Berlin questionnaire. There was a statistically significant and moderate positive correlation between the variables Body Mass Index (BMI) and the Berlin questionnaire scores. Conclusion: Individuals complaining of snoring self-reported difficulties related to sleep quality. The sleep quality difficulties self-reported were related to data on orofacial motricity, eating habits, body composition and lifestyle habits. (AU)

RESUMO

Abstract Introduction Laser uvulopalatoplasty is an established operation for the treatment of snoring with good results on a short-term basis, while long-term follow-up studies, in addition to their scarcity, had conflicting results regarding recurrence, the change of snoring quality, and complications. Objective To assess the long-term follow-up results of using nonablative 2,940 nm Erbium: YAG for the treatment of snoring regarding outcomes and recurrence. Methods This 2-year follow-up study was conducted on 76 patients operated upon by non-ablative 2940 nm Erbium: yttrium-aluminum-garnet (YAG) using a PS01 patterned headpiece. Subjective evaluation of the treatment was performed relying on a smartphone application to record snoring in addition to a questionnaire specially designed to report recurrence and change in the quality of snoring reported by a patient's spouse. The objective evaluation was done by computed tomography (CT) imaging of the soft palate. The patients were evaluated preoperatively, 6 weeks postoperatively and after a 2-year follow-up period. Results Six week after the procedure, there was a significant improvement in 52 patients (68.4%). Out of the 52 patients, only 43 completed the 2-year follow-up; however, 15 of them complained of recurrence. Nevertheless, the patients who suffered from recurrence showed subjective improvement in snoring quality. Conclusions The nonablative mode of Erbium: YAG 2,940 nm laser proved to be efficient in soft palate tightening for the management of snoring. However, there was recurrence in 34.8% of the patients who presented objective and subjective improvement of the complaints, 6 weeks postoperatively and after a 2-year follow-up period.

RESUMO

OBJECTIVE: The American Academy of Pediatrics recommends routine sleep problem screenings during child well-visits. However, studies suggest a discrepancy between caregiver- and clinician-reported child sleep problems. The present study examines whether caregiver-reported child sleep problems (ie, habitual snoring, insomnia symptoms, poor sleep health) and clinician-documented child sleep problems and management are congruent. METHODS: The sample included 170 caregiver-child dyads (child Mage = 3.3 years, range = 2-5 years; 56.5% girls; 64.1% Black, 20.0% non-Latinx White, and 4.1% Latinx; 86.5% maternal caregiver reporter). Caregivers' questionnaire-based reports of habitual snoring, insomnia symptoms, and sleep health behaviors (nighttime electronics, caffeine intake, insufficient sleep) were compared with clinician documentation in the electronic health record. RESULTS: About 92.3% of children had at least 1 caregiver-reported sleep problem (66% insomnia symptoms, 64% electronics, 38% insufficient sleep, 21% caffeine, 17% snoring). In contrast, a substantially lower percent of children had a clinician documented sleep problem (20% overall; 10% insomnia symptoms, 7% electronics, 0% insufficient sleep, 3% caffeine, 4% snoring), sleep-related referral (1% overall; 0.6% Otolaryngology, 0.6% polysomnogram, 0% sleep clinic), or recommendation (12% overall; 8% insomnia symptoms, 4% electronics, 0% insufficient sleep, 1% caffeine). CONCLUSIONS: There is a vast discrepancy between caregiver-reported child sleep problems and clinician-documented sleep problems and management, with a higher proportion of caregiver reports. To benefit overall child health and well-being, future research and quality improvement initiatives should focus on enhancing screening tools and educational opportunities to improve clinician documentation and enhance family conversations about early childhood sleep problems.

RESUMO

PURPOSE: This study aimed to evaluate the quality of sleep, presence of obstructive sleep apnea (OSA), and its relationship with the presence of snoring, cephalometric characteristics, degree of collapse of the upper airways, and orofacial myofunctional profile in obese and overweight individuals. METHODS: All participants completed polysomnography, as well as sleep and snoring questionnaires. We further performed orofacial, otorhinolaryngological, and anthropometric evaluations on all participants. RESULTS: A total of 102 adults, comprising 29 obese, 21 overweight, and 52 eutrophic individuals of both sexes participated in this study. We observed a high prevalence of snoring in both obese and overweight (100%), and in 65% of eutrophic individuals. Among the obese subjects 58% had a severe degree of OSA, whereas 4% of eutrophic subjects presented a risk for OSA development. Sleep quality was related to body mass index (BMI) and cervical and abdominal circumference. All obese and overweight individuals presented with orofacial myofunctional alterations such as facial asymmetry, alteration of the maxilla-jaw relationship, inadequate tongue posture, changes in masticatory pattern and swallowing, and inadequate general orofacial myofunctional condition. Airway obstructions at the retropalatal and retrolingual levels > 75% were observed in at least 48% of the individuals. CONCLUSION: Obese and overweight individuals presented a higher risk for the development of OSA compared with eutrophic patients, and obese individuals presented a greater severity of OSA. The higher the BMI and greater the cervical and abdominal circumferences, the higher the prevalence of OSA, worse the quality of sleep, and more serious orofacial myofunctional characteristics in this population.

RESUMO

La terapia miofuncional orofacial (TMO) ha tenido un creciente desarrollo durante la última década, presentándose como una opción terapéutica en pacientes con AOS. Sin embargo, la evidencia es limitada y en Chile no hay mucho conocimiento al respecto. Se desarrolló una revisión sistemática en PubMed, MEDLINE, Embase, Web of Science, Lilacs y Scielo, que incluyó estudios primarios publicados en los últimos 10 años en idioma inglés, español o portugués y que utilizaran la TMO en pacientes adultos con AOS. Se excluyeron estudios que combinaran otras estrategias, con alteraciones miofuncionales secundarias a patologías concomitantes y con otro tipo de trastorno del sueño. La revisión consideró 9 artículos en su análisis; los resultados mostraron beneficios significativos a favor de la TMO en relación a disminución del índice de apnea-hipopnea, mejor calidad del sueño, nivel de somnolencia de Epworth, menor intensidad y frecuencia de los ronquidos, menor circunferencia del cuello, entre otros. Se concluye que la TMO genera beneficios en los pacientes con AOS, siendo una opción no invasiva y accesible.

Orofacial myofunctional therapy (OMT) has had a growing development during the last decade, presenting itself as a therapeutic option in patients with OSA. However, the evidence is limited and in Chile there is not much knowledge about it. A systematic review was developed in PubMed, MEDLINE, Embase, Web of Science, Lilacs and Scielo, which included primary studies published in the last 10 years in English, Spanish or Portuguese that used OMT in adult patients with OSA. Studies that combined other strategies, with myofunctional alterations secondary to concomitant pathologies and with another type of sleep disorder were excluded. The review considered 9 articles in its analysis; The results showed significant benefits in favor of OMT in relation to a decrease in the apnea-hypopnea index, better sleep quality, Epworth sleepiness level, less intensity and frequency of snoring, less neck circumference, among others. It is concluded that OMT generates benefits in patients with OSA, being a non-invasive and accessible option.

RESUMO

RESUMEN: El objetivo de este estudio fue determinar las actitudes y la conciencia de los odontólogos y especialistas médicos sobre la provisión de dispositivos de avance mandibular (DAM) para el tratamiento de los ronquidos y la apnea del sueño. Se llevó a cabo un estudio observacional descriptivo de corte transversal, donde se seleccionaron por conveniencia 53 odontólogos (generales y especialistas) y 5 médicos especialistas en medicina del sueño en la ciudad de Guadalajara, México. Quienes respondieron un cuestionario específico desarrollado por Jauhar et al. (2008) dirigido a conocer la actitud de los odontólogos y médicos especialistas para la provisión de los DAM y otros aspectos relacionados con el ronquido y la apnea obstructiva del sueño (AOS). El 94 % de los odontólogos respondió estar interesado en capacitarse en ronquido y AOS. Y en el grupo de los médicos especialistas se encontró que el 80 % cree que los odontólogos sí tienen un papel para ayudar a los pacientes con ronquido y AOS, el 60 % cree que los odontólogos pueden contribuir con la realización de DAM y el 40 % considera que los odontólogos deben remitir a un especialista del sueño. Existe una actitud muy positiva de los odontólogos para ser parte del grupo interdisciplinario para el tratamiento del ronquido y de la apnea obstructiva del sueño, pero este estudio nos muestra además que a pesar de la disposición para utilizar los DAM, la formación y capacitación no es suficiente. Por otra parte, hay una actitud positiva de los médicos especialistas que consideran que los odontólogos juegan un papel importante en ayudar a los pacientes con ronquidos o con apnea del sueño, pero se evidencia que en su gran mayoría no usan los DAM como parte de un posible tratamiento.

ABSTRACT: The objective of this study was to determine the attitudes and awareness of dentists and medical specialists on the provision of mandibular advancement devices (MAD) for the treatment of snoring and sleep apnea. This is a cross-sectional descriptive observational study, where 53 dentists (general and specialists) and 5 sleep medicine specialists in the city of Guadalajara, Mexico were selected for convenience. The selected group answered a specific questionnaire developed by Jauhar et al., to know the attitude of dentists and medical specialists for the provision of MAD and other aspects related to snoring and obstructive sleep apnea (OSA). 94 % of dentists responded to be interested in training in snoring and OSA. And of the group of medical specialists, 80 % consider that dentists have a role in helping patients with snoring and OSA, 60 % believe that dentists can contribute to MAD and 40 % believe that dentists should refer a sleep specialist. There is a very positive attitude by the dentists to be part of the interdisciplinary group for the treatment of snoring and obstructive sleep apnea, but this study also shows that despite the willingness to use MAD, education and training is not enough. There is a positive attitude of specialist doctors who consider that dentists play an important role in helping patients with snoring or with sleep apnea, but it is evident that the majority do not use MAD as part of a possible treatment.

RESUMO

The association between obstructive sleep-disordered breathing (oSDB) and arterial stiffness, an independent predictor of cardiovascular outcomes, is not well established in children. This study compared cardiovascular parameters between healthy and oSDB children and aimed to identify predictors of arterial stiffness indices in children with oSDB. Cross-sectional study realized in a tertiary hospital from June 2018 to January 2020. Forty-eight children (3 to 10 years old) with clinical diagnosis of oSDB and indication for adenotonsillectomy and 24 controls were evaluated. Cardiovascular parameters were measured non-invasively by brachial artery oscillometry with a portable device. The main arterial stiffness indices assessed were augmentation index and pulse wave velocity, both derived from the aortic pulse wave. In the oSDB group, the questionnaires Obstructive Sleep Apnea-18 (OSA-18) and Pediatric Quality of Life Inventory version 4.0 (PedsQL 4.0) were applied. The oSDB group had higher values of reflection coefficient (p = 0.044) and augmentation index (p = 0.003) than the control group. Stepwise multiple regression analysis revealed that age, female sex, reflection coefficient, and systolic volume were independent predictors of augmentation index. Higher pulse wave velocity values were associated with worse quality of life assessed by PedsQL 4.0 questionnaire. There was no association with OSA-18. The vascular and hemodynamic parameters were similar in both groups.Conclusion: Children with oSDB have increased augmentation index, an independent predictor of cardiovascular outcomes. The early identification of subclinical cardiovascular changes reinforces the importance of treating the disease, as well as changing lifestyle habits, to prevent complications in adulthood. What is Known: • The association between oSDB and cardiovascular risk in adults is well described in the literature. • Children with oSDB, regardless of their weight or sex, have higher PWV values when compared to non-snoring children. What is New: • Children with oSDB have augmented arterial stiffness, evidenced by the increase in AIx@75, measured non-invasively by brachial artery oscillometry with a portable device. • Low quality of life and therefore a high disease burden in children with oSDB may be a risk factor for arterial stiffness.
