Rapid maxillary expansion in pediatric patients with obstructive sleep apnea: an umbrella review

Abstract Objective To compare polysomnographic parameters with others from the literature in order to provide more accurate information about Rapid Maxillary Expansion (RME) for treating Obstructive Sleep Apnea (OSA) in children, through raising the question: Is RME a good option for treating OSA in children? Prevention of mouth breathing during children's growth remains a challenge with significant clinical consequences. In addition, OSA induces anatomofunctional changes during the critical period of craniofacial growth and development. Methods The Medline, PubMed, EMBASE, CINAHL, Web of Science, SciELO and Scopus electronic databases were searched up to February 2021 for systematic reviews with meta-analysis in the English language. Among 40 studies on RME for treating OSA in children, we selected seven in which polysomnographic measurements of the Apnea-Hypopnea Index (AHI) had been made. Data were extracted and examined in order to clarify whether any consistent evidence exists for indicating RME as a treatment for OSA in children. Results We found no consistent evidence favoring RME for long-term treatment of OSA in children. All the studies presented considerable heterogeneity due to variability of age and length of follow-up. Conclusion Through this umbrella review, the need for methodologically better studies on RME is supported. Moreover, it can be considered that RME is not recommended for treating OSA in children. Further studies and more evidence identifying early signs of OSA are necessary in order to achieve consistent healthcare practice.

Insomnia in older HIV-positive patients.

Introduction: Insomnia is a common sleep disorder in elderly. Although the HIV-positive population have a similar life expectancy when compared to the general population, some factors may interact with immunity conditions and therefore contribute to a worse prognosis. Objective: This is a review of literature that aims to identify prevalence of insomnia in older HIV-positive patients. Material and Methods: This is a review of literature conducted by using MEDLINE-PubMed, Embase, Cochrane Library, CINAHL, Web of Science, Scopus, SciELO, LILACS, and VHL databases, in addition to conducting manual searches. The terms used for the search were related to prevalence, HIV, insomnia, and advanced age. Inclusion criteria were: cross-sectional, cohort, and longitudinal studies, patients with a previous diagnosis of HIV in old age, studies reporting the frequency of insomnia or insomnia symptoms. The criteria for exclusion were: clinical trials, animal studies, letters, abstracts, conference proceedings, studies with other sleep scales that did not include insomnia. Results: There were 2,805 publications found in the database and a further 10 articles were included manually. Of this total, four were included in this review, resulting in a total of 2,227 participants. The prevalence of insomnia in HIV-positive patients over 50 years varied from 12.5% to 76.5%. Conclusion: The frequency of insomnia was higher in the profile of the population studied than in the general population. This should be clinically relevant in order to adequately treat and impact on the prognosis of those patient.

Impact of L-carnitine in narcolepsy treatment: a systematic review on the effectiveness and safety.

Introduction: Studies have shown that narcolepsy patients may present with low serum acylcarnitine levels, demonstrating a dysfunctional beta fatty acid oxidation pathway in these patients. Objective: Evaluate the therapeutic efficacy of L-carnitine as a treatment for narcolepsy patients. Methods: This study runned in form of systematic review. The terms used for the search: ("narcolepsy"[MeSH Terms] OR "narcolepsy"[All Fields]) AND ("carnitine"[MeSH Terms] OR "carnitine"[All Fields] OR "l carnitine"[All Fields]). Were included all surveys published until January 2021, with the diagnosis of narcolepsy, that performed drug treatment with I-carnitine. The clinical endpoints of interest were: excessive daytime sleepiness, dissociative REM sleep manifestations: cataplexy, sleep paralysis, hypnagogic hallucinations, and early REM sleep (REM sleep naps, SOREMP). Results: L-carnitine was found to be well-tolerated and without side effects in all surveys, at dosages ranging from 500 to 510 mg/day. Newborns did not present complications during delivery. Conclusion: This study corroborates the efficacy and good tolerability of L-carnitine therapy as a treatment for patients with narcolepsy, including during pregnancy.

Insomnia and circadian misalignment: an underexplored interaction towards cardiometabolic risk.

Insomnia remains the most prevalent sleep disorder worldwide, and its pathophysiology suggests an interface with circadian rhythm sleep-wake disorders (CRSWDs). Some epidemiological studies have linked insomnia and circadian misalignment with adverse cardiometabolic outcomes, but the mechanisms underlying this relationship are still unclear. The autonomic nervous system (ANS) has been pointed out as a crucial/key mediator that triggers cardiometabolic risk. Therefore, a critical review of the literature focused on the past ten years was conducted to highlight the relationship between insomnia, circadian misalignment and cardiometabolic risk, with particular emphasis on the influence of the ANS. Shift work, as a model of circadian misalignment, was shown to increase both cardiovascular and metabolic risk and so may integrate a proof of concept on this link. Furthermore, there is good evidence from previous studies supporting that cardiac autonomic dysfunction is indeed a possible mechanism that potentiates cardiometabolic risk in insomniacs and individuals with a misalignment of the circadian timing system (e.g., shift workers), via changes in autonomic variables. Further research is however required in order to definitively establish this interactive relationship.

The effect of biofeedback on pain and sleep in a patient with temporomandibular disorder. Case report / Efeito do biofeedback na dor e no sono de paciente com disfunção temporomandibular. Relato de caso

ABSTRACT BACKGROUND AND OBJECTIVES: Literature has shown that behavioral and educational modalities are effective options in the treatment of chronic pain, including temporomandibular disorder, and techniques such as biofeedback have been used for single therapy or in combination for effective pain control in these individuals. Furthermore, the severity of symptoms is related to relevant prognostic factors, such as quality of life, emotional states and sleep quality. The aim of the present study was to evaluate the effect of the biofeedback audiovisual technique on pain control and sleep quality in a patient with temporomandibular disorder. CASE REPORT: Female patient, 34 years old, with Temporomandibular Disorder. The DC/TMD (Diagnostic Criteria for Temporomandibular Disorders) Axis I, diagnostic was applied, and the patient was classified with more than one subtype of temporomandibular disorders: local myalgia and myofascial pain with reference, in addition to neck pain as a comorbidity. CONCLUSION: In this case, the biofeedback treatment was effective both in reducing pain intensity and improving sleep quality.

RESUMO JUSTIFICATIVA E OBJETIVOS: A literatura tem demonstrado que as modalidades comportamentais e educacionais são opções efetivas no tratamento da dor crônica, inclusive da disfunção temporomandibular, e técnicas como o biofeedback vêm sendo utilizadas como terapia isolada ou em combinação para um controle efetivo da dor nesses indivíduos. Além disso, a gravidade dos sintomas tem correlação com fatores de relevância para o prognóstico, como a qualidade de vida, estados emocionais e qualidade do sono. O objetivo deste estudo foi avaliar o efeito da técnica do biofeedback audiovisual no controle da dor e na qualidade do sono em paciente com disfunção temporomandibular muscular. RELATO DO CASO: Paciente do sexo feminino, 34 anos, com disfunção temporomandibular. O critério diagnóstico DC/TMD (Diagnostic Criteria for Temporomandibular Disorders) Eixo I foi aplicado, sendo a paciente classificada com mais de um subtipo de disfunção temporomandibular: mialgia local e dor miofascial com referência, além de cervicalgia como comorbidade. CONCLUSÃO: No caso clínico apresentado a terapia com biofeedback foi efetiva na redução da intensidade da dor e melhoria da qualidade do sono.

A singular oral appliance to treat obstructive sleep apnea in CPAP non-adherent patients.

INTRODUCTION: The most prescribed treatment option for Obstructive Sleep Apnea (OSA) is CPAP; however, its adherence is limited. Oral Appliance therapy (OAT) is frequently an option or even an adjuvant, being the mandibular advancement Oral Appliance (OAm) the most used prescription. It modifies the upper airway, improving the airway patency. OAm construction is based on the occlusal plane to disocclusion. In this study, the DIORS® appliance was used, a singular OAm, based on Neuro-Occlusal Rehabilitation concepts, that uses Camper's plane as a disocclusion reference, in order to achieve neuromuscular balance and functional stability. OBJECTIVE: This study primarily aimed to assess the DIORS® effectiveness in relation to clinical and polysomnographic outcomes. It was also evaluated if the use of DIORS® is as effective as titrated CPAP to treat CPAP non-adherent patients. METHODS: Twenty patients were included in this study. Objective and subjective clinical data were assessed at a sleep laboratory using all-night polysomnography, and Epworth Sleepiness Scale (ESS), taken at three moments: Baseline, CPAP titration, and using DIORS®. Analysis of respiratory parameters as apnea/hypopnea index (AHI), oxyhemoglobin saturation levels, the arousal index and daytime sleepiness were taken as criteria for a successful OAT. RESULTS: Respiratory and arousal parameters improved in both therapies, while DIORS® promoted a better ESS. CONCLUSION: Results from the present work support that DIORS® is a viable and effective adjuvant therapy for patients with moderate to severe OSA non-adherent to CPAP.

RESUMO Introdução: A opção mais indicada para tratamento da apneia obstrutiva do sono (AOS) é o CPAP; contudo, a aderência é limitada. A Terapia com Aparelho Oral (TAO) é, frequentemente, uma opção, ou mesmo um adjuvante. A prescrição mais utilizada é o Aparelho Oral de avanço mandibular (AOm). O AOm modifica a via aérea superior, melhorando a patência do espaço aéreo. A construção do AOm se baseia no plano de oclusão para desoclusão. No presente estudo, usamos o DIORS®, um AOm diferente, baseado nos conceitos da Reabilitação Neuro-Oclusal (RNO), que utiliza o Plano de Camper como referência da desoclusão para alcançar o equilíbrio neuromuscular e estabilidade funcional. Objetivo: O presente estudo teve como objetivo principal abordar a eficácia do DIORS®, considerando-se os resultados clínicos e polissonográficos. Adicionalmente, foi avaliado, também, se o uso desse AOm é tão eficaz quanto a titulação do CPAP para tratar pacientes com AOS não aderentes ao CPAP. Métodos: Vinte pacientes foram incluídos neste estudo. Dados clínicos objetivos e subjetivos foram avaliados em um laboratório de sono usando polissonografia de noite inteira e a Escala de Sonolência de Epworth (ESE) observando-se três momentos: inicial, titulação do CPAP e usando o DIORS®. Os critérios de sucesso da TAO foram assumidos pela análise dos parâmetros respiratórios como Índice de Apneia e Hipopneia (IAH) e níveis de saturação de oxi-hemoglobina, o índice de despertar e a sonolência diurna. Resultados: Em ambas as terapias, os parâmetros respiratórios e de despertares melhoraram. Adicionalmente, uma melhora na ESE foi alcançada com o DIORS®. Conclusão: Os resultados do presente trabalho apoiam que o DIORS® é uma terapia adjuvante viável e bastante eficaz para pacientes com AOS moderada a grave não aderentes ao CPAP.

Pain perception and quality of life in burning mouth syndrome / Percepção da dor e qualidade de vida na síndrome da boca ardente

ABSTRACT BACKGROUND AND OBJECTIVES: Burning mouth syndrome is a dysfunctional state affecting physical, mental and social welfare, often contributing to chronic stress conditions. Despite the lack of objective data, patients experience pain-related discomfort with impact in their daily life. The objective of this study was to assess the impact of burning mouth syndrome on pain perception and quality of life. METHODS: A cross-sectional, observational, case-controlled study was performed on 76 individuals (38 in each group). The groups were sex- and age-matched. The Oral Health Impact Profile (OHIP-14) questionnaire was used to assess any changes in the quality of life. The visual analog scale was used to assess pain impact and intensity, as well as the Pain Catastrophizing Scale (PCS). The effect of sex and other risk factors associated with burning mouth syndrome were also associated. RESULTS: The age of participants was 41 to 85 years. The patients had a negative impact on quality of life with respect to all dimensions of OHIP-14 and PCS domains. Burning mouth syndrome patients complained about moderate (58%) or intense (42%) pain, while the control group participants experienced only mild pain by visual analog scale. The prevalence was predominant in females (a ratio of 3:1), and the most site involved was the tongue. Menopause, hormonal changes, and gastritis were identified as major risk factors. CONCLUSION: Burning mouth syndrome patients had significantly higher PCS and OHIP-14 scores for all domains, indicating an interaction between a higher burden of pain perception and worse quality of life which should therefore be adequately assessed, characterized and managed.

RESUMO JUSTIFICATIVA E OBJETIVOS: A síndrome de ardência bucal é um estado disfuncional que afeta o bem-estar físico, mental e social, contribuindo para condições de estresse crônico. Apesar da ausência de dados objetivos, os pacientes experimentam desconforto relacionado à dor com impacto na vida diária. O objetivo deste estudo foi avaliar o impacto da síndrome da boca ardente na percepção da dor e na qualidade de vida. MÉTODOS: Foi realizado um estudo transversal, observacional e caso-controle em 76 indivíduos, 38 em cada grupo, pareados por gênero e idade. Foram utilizados o questionário Oral Health Impact Profile (OHIP-14) para avaliar mudanças na qualidade de vida, a escala analógica visual para o impacto e intensidade da dor e a Pain Catastrophizing Scale (PCS). Foi avaliado também o efeito do sexo, idade e outros fatores de risco associados à síndrome de ardência bucal. RESULTADOS: A idade dos participantes foi de 41 a 85 anos. A síndrome de ardência bucal teve um impacto negativo na qualidade de vida em todas as dimensões dos domínios OHIP-14 e PCS. Cinquenta e oito por cento dos pacientes se queixaram de dor moderada e 42% de dor intensa, enquanto os controles experimentaram apenas dor leve pela escala analógica visual. A prevalência foi predominante no sexo feminino (3:1), e a língua foi o local envolvido mais comum. Menopausa, alterações hormonais e gastrite foram os maiores fatores de risco. CONCLUSÃO: Os pacientes com síndrome de ardência bucal apresentaram escores PCS e OHIP-14 mais altos para todos os domínios, indicando uma interação entre maior carga de percepção da dor e pior qualidade de vida, o que deve ser mais bem avaliado, caracterizado e gerenciado.
