Association between the intensity of obstructive sleep apnea and skeletal alterations in the face and hyoid bone

IntroductionThe association between the intensity of obstructive sleep apnea and skeletal alterations in the face and hyoid bone is still scarcely addressed in the literature.ObjectiveTo evaluate whether the intensity of obstructive sleep apnea is associated with craniofacial alterations and the position of the hyoid bone in children with mixed dentition.Methods76 children aged 7 to 10 years old were examined by otorhinolaryngological evaluation, polysomnography, and orthodontic assessment, including cephalometry. The participants were divided in 3 groups: primary snoring, mild obstructive sleep apnea and moderate to severe obstructive sleep apnea. Cephalometric measures of the face and hyoid bone were assessed. These measures were compared among the different groups by unpaired Student's t test. Moreover, these measures were correlated with the patient's obstructive apnea and hypopnea index variable using Pearson's correlation test.ResultsOf the 76 children, 14 belonged to group 1, with primary snoring; 46 to group 2, with mild obstructive sleep apnea; and 16 to group 3, with moderate-severe obstructive sleep apnea. There was no difference between the groups regarding the craniofacial variables. Children with obstructive sleep apnea showed a longer distance from the hyoid bone to the mandibular plane when compared to the primary snoring group (p < 0.05). Between the two obstructive sleep apnea subgroups, patients with moderate or severe disease showed significantly shorter horizontal distance between the hyoid bone and the posterior pharyngeal wall (p < 0.05), when compared to the groups with mild obstructive sleep apnea. We also observed a significant positive correlation between obstructive apnea and hypopnea index and the distance from the hyoid to the mandibular plane (p < 0.05) as well as a significant negative association between obstructive apnea and hypopnea index and the horizontal distance from the hyoid to the posterior pharyngeal wall (p < 0.01).ConclusionWe did not observe any association between obstructive sleep apnea and linear lateral alterations of the face. In contrast, there is a direct association between obstructive sleep apnea severity and the inferior and posterior position of the hyoid bone in children aged 7 to 10 years old.     

睡眠呼吸障碍为首发表现的Chiari畸形幼儿1例报道并文献复习

目的 探讨中枢性睡眠呼吸暂停的特点及其引起疾病的临床特征,提高Chiari畸形合并中枢性睡眠呼吸暂停的认识。 方法 回顾性分析1例以睡眠呼吸障碍为首发表现的Chiari畸形患儿的临床资料,结合文献复习探讨Chiari畸形合并中枢性睡眠呼吸暂停(CSA)的特征。 结果 患儿通过影像学及多导睡眠监测证实符合Chiari畸形Ⅰ型合并CSA的特征。结合病例,复习、汇总国内外文献关于Chiari畸形的研究报道,共32例(成年男性1例,成年女性4例,幼儿男性12例,幼儿女性15例)。合并睡眠呼吸障碍22例,其中13例以阻塞型暂停为主、5例以中枢型暂停为主、1例为中枢型低通气、3例表现为中枢型和阻塞型并存。除1例合并阻塞型暂停患者行无创正压通气治疗,其他患者均行外科手术治疗。 结论 Chiari畸形引起睡眠呼吸障碍的问题不容忽视,多导睡眠监测可以对睡眠呼吸特点进行客观评估和初步诊断,为临床治疗决策前提供更多的客观诊断依据。

Postprandial hyperglycemia in type 2 diabetes and obstructive sleep apnea

ObjectivesPostprandial hyperglycemia is common in type 2 diabetes even in those with acceptable glycemic control and conveys an increased risk of cardiovascular morbidity and mortality. Although obstructive sleep apnea (OSA) has been associated with altered glucose metabolism, data regarding its association with postprandial hyperglycemia in type 2 diabetes are limited. Thus, the current study sought to characterize the association between OSA and postprandial hyperglycemia in adults with type 2 diabetes.MethodsA cross-sectional study of adults with type 2 diabetes was conducted. Home sleep testing was used to assess OSA severity as determined by the oxygen desaturation index (ODI). Self-monitoring of blood glucose (SMBG) was performed before and 2-h after breakfast, lunch, and dinner for three days. The association between OSA and glucose levels before and after each meal was examined using multivariable logistic regression.ResultsThe study sample consisted of 195 adults with 52% being men. OSA severity, as assessed by ODI quartiles, was associated with higher postprandial glucose values after dinner but not after breakfast or lunch. The adjusted odds ratios (95% confidence intervals) for a higher post-dinner glucose level for four ODI quartiles were 1.00 (Reference), 2.16 (0.96, 4.87), 2.23 (1.03, 4.83), and 2.58 (1.18, 5.94). Stratified analyses showed that this association was present in men but not women.ConclusionsIncreasing OSA severity is associated with postprandial hyperglycemia in type 2 diabetes and may contribute to impaired glycemic control. Future studies examining the impact of OSA treatment on glucose metabolism should consider meal-related glycemic excursions as a potential outcome.     

Alternatives to surgery in children with mild OSA

Precision medicine requires coordinated and integrated evidence-based combinatorial approaches so that diagnosis and treatment can be tailored to the individual patient. In this context, the treatment approach to mild obstructive sleep apnea (OSA) is fraught with substantial debate as to what is mild OSA, and as to what constitutes appropriate treatment. As such, it is necessary to first establish a proposed consensus of what criteria need to be employed to reach the diagnosis of mild OSA, and then examine the circumstances under which treatment is indicated, and if so, whether and when anti-inflammatory therapy (AIT), rapid maxillary expansion (RME), and/or myofunctional therapy (MFT) may be indicated.     

肥胖儿童阻塞性睡眠呼吸暂停的临床特征

目的 研究肥胖儿童合并阻塞性睡眠呼吸暂停（obstructive sleep apnea，OSA）的临床特征。 方法 对在深圳市儿童医院呼吸科行多导睡眠监测的肥胖并诊断为OSA的33例7~15岁儿童的临床资料进行回顾性分析，并选取50例体重正常的、性别及年龄相匹配的OSA患儿作为对照组。 结果 33例合并肥胖的OSA儿童中，常见的日间症状前3位为：注意力不集中30例（91%），嗜睡22例（67%），晨起疲劳21例（64%）；夜间症状前3位为：打鼾27例（82%），张口呼吸20例（61%），出汗16例（48%）。与正常儿童参考值相比，肥胖OSA组和对照组两组患儿浅睡眠延长，深睡眠缩短，快速动眼期明显缩短，但两组之间这些指标的比较差异无统计学意义（P>0.05）。与对照组比较，肥胖OSA组呼吸暂停低通气指数和阻塞性呼吸暂停低通气指数均显著增加（P<0.05）；快速动眼期及非快速动眼期氧减指数均显著增加（P<0.05）；肥胖OSA组睡眠期间最低血氧饱和度显著低于对照组（P<0.05）。 结论 肥胖合并OSA儿童临床日间症状以注意力不集中、嗜睡、晨起疲劳为主，夜间症状以打鼾、张口呼吸、出汗为主。与体重正常OSA患儿相比，肥胖合并OSA儿童的睡眠结构无明显差别，但呼吸事件及血氧饱和度下降更严重。 引用格式:
