Obstructive Sleep

Objective To determine common polysomnographic (PSG) diagnoses for children referred by otolaryngologists. Study Design Retrospective case series with chart review. Setting Single tertiary pediatric hospital (2010-2015). Subjects and Methods Review of the medical records of 1258 patients undergoing PSG by otolaryngology referral. Patients who underwent previous otolaryngologic surgery were excluded. Data distributions were evaluated using means with standard deviations for continuous variables and frequencies with percentages for categorical variables. Results A total of 1258 patients were included; 55.9% were male, 64.5% were Caucasian, 16.6% had Down syndrome, and 48% had public insurance. The median age at the time of PSG was 5.2 years (range = 0.2-18.94). Indications for PSG were sleep-disordered breathing (SDB; 69.4%), restless sleep (12.7%), airway anomalies (7.5%), and laryngomalacia (7.2%). SDB was seen in 73.4%, obstructive sleep apnea (OSA) in 53.2%, OSA + central sleep apnea (CSA) in 4.5%, CSA in 0.9%, and non-OSA snoring in 15%. Other diagnoses included periodic limb movements of sleep (PLMS; 7.4%), hypoventilation (6.8%), and nonapneic hypoxemia (2.6%). SDB was more common in younger children and seen in 91.4% of children <12 months and in 69.2% of children ≥24 months, while non-OSA snoring was more common with increasing age (3.7% in children <12 months, 17.7% of children ≥24 months). PLMS were seen in 8.9% of children ≥24 months and in no children <12 months. Conclusion While OSA and snoring were the most common diagnoses reported, PLMS, alveolar hypoventilation, and CSA occurred in 7.4%, 6.8%, and 5.4%, respectively. These findings indicate that additional diagnoses other than OSA should be considered for children seen in an otolaryngology clinic setting who undergo PSG for sleep disturbances.

Sweet Spots

Objectives: Severe pain on swallowing (or dynamic pain) has long been a problem in patients receiving tonsillectomy and uvulopalatopharyngoplasty for the treatment of obstructive sleep apnea syndrome and/or snoring. We have previously verified that dynamic pain after laser-assisted uvulopalatoplasty could immediately be mitigated by local treatments with topical triamcinolone on the “sweet spots” of the wounds. This study aimed to assess the efficacy of applying triamcinolone on “sweet spot” in surgical incisions instead of whole surgical wounds to alleviate dynamic pain of some oropharyngeal surgeries such as tonsillectomy and uvulopalatopharyngoplasty. Methods: This study is a retrospective case series based on chart review of the participants. Forty-five subjects (31 males; 12~68 years, mean 34 years) with obstructive sleep apnea syndrome and/or snoring treated with tonsillectomy or uvulopalatopharyngoplasty were studied. Local treatments were done to sweet spots with triamcinolone on the 1st, 2nd, 3rd, and 7th days after the surgery. Evaluation of dynamic pain relief was performed by using a visual analogous scale. Results: Sweet spots treatment led to instantaneous reduction of dynamic pain. The average improvement level was ≥72% ( P ≤ .002). No gender effect was noted. Conclusion: Dynamic pain after tonsillectomy and uvulopalatopharyngoplasty could immediately be mitigated by local treatments upon sweet spots. Local treatments upon sweet spots were highly suggested to begin early post-operatively and be included in the take-home routines for patients receiving tonsillectomy and uvulopalatopharyngoplasty.

Objective.To examine the extent of polysomnographic (PSG) sleep disturbances [obstructive apnea hypopnea index (OAHI), number of wake bouts, arousals, periodic limb movements] and the effect of OAHI on neurobehavioral performance in juvenile idiopathic arthritis (JIA) with obstructive sleep apnea (OSA), JIA without OSA, and controls without OSA, adjusting for intelligence quotient (IQ), pain, medications, daytime sleepiness, and wake bouts.Methods.Children 6–11 years, 68 with JIA and 67 controls, underwent 1 night of PSG and completed self-reported daytime sleepiness surveys, multiple sleep latency tests for physiological sleepiness, and neurobehavioral performance tests the next day.Results.Compared with JIA and controls without OSA, mean OAHI and arousals were significantly higher in JIA with OSA (p < 0.001, respectively). In comparison with JIA and controls without OSA, mean simple reaction time and sustained attention were significantly slower in JIA with OSA, adjusting for IQ, pain, any medication, daytime sleepiness, and wake bouts.Conclusion.Elevated OAHI is suggestive of obstructive sleep apnea and a comorbidity in JIA that may predispose children with JIA to daytime sleepiness and impaired neurobehavioral performance.

Abstract Introduction Sleep-disordered breathing is common in persons with multiple sclerosis (PwMS), and may contribute to debilitating fatigue and other chronic MS symptoms. The majority of research to date on SDB in MS has focused on the prevalence and consequences of obstructive sleep apnea; however, PwMS may also be at increased risk for central sleep apnea (CSA), and the utility of methods to assess CSA in PwMS warrant further exploration. We present a patient with secondary progressive multiple sclerosis who was found to have severe central sleep apnea on WatchPAT testing. Report of case(s) A 61 year-old female with a past medical history of secondary progressive multiple sclerosis presented with complaints of fragmented sleep. MRI of the brain, cervical spine, and thoracic spine showed numerous demyelinating lesions in the brain, brainstem, cervical, and thoracic spinal cord. Upon presentation, the patient noted snoring, witnessed apneas, and daytime sleepiness. WatchPAT demonstrated severe sleep apnea, with a pAHI of 63.3, and a minimum oxygen saturation of 90%. The majority of the scored events were non-obstructive in nature (73.1% of all scored events), and occurred intermittently in a periodic fashion. Conclusion The differential diagnosis of fatigue in PwMS should include sleep-disordered breathing, including both obstructive and central forms of sleep apnea. Demyelinating lesions in the brainstem (which may contribute to impairment of motor and sensory networks that control airway patency and respiratory drive), and progressive forms of MS, have been linked to both OSA and CSA. The present data illustrate this relationship in a person with progressive MS, and offer support for the WatchPAT as a cost-effective means to evaluate for both OSA and CSA in PwMS, while reducing patient burden. PwMS may be at increased risk for CSA. Careful clinical consideration should be given to ordering appropriate sleep testing to differentiate central from obstructive sleep apnea in PwMS, particularly for patients with demyelinating lesions in the brainstem.

AbstractThe aim of the study was to assess the factors associated with periodic limb movements during sleep (PLMS) among obstructive sleep apnea syndrome (OSAS) patients and identify the role of PLMS in patients with OSAS. 303 adult patients with OSAS were included in the study. All patients completed physical examination, Epworth sleepiness scale (ESS), and polysomnography. Diagnosis of PLMS was made if the periodic leg movements index (PLMI) was ≥ 15. Chi-square test, ANOVA, univariate and multivariate logistic regression analyses were conducted to identify factors associated with PLMS among OSAS patients. Statistical analyses were performed with SPSS 26.0 for mac. Statistically significant difference was considered if P value < 0 .05. Among the 303 adult patients with OSAS, 98 patients had significant PLMS and the other 205 had no significant PLMS. Compared with OSAS patients without PLMS, OSAS patient with PLMS were older, had shorter REM duration and greater apnea–hypopnea index (AHI) (P < 0.05). The study suggests that PLMS is a matter of concern among patients with OSAS. A better understanding of the role of PLMS among OSAS patients could be useful in better recognition, intervention and treatment of OSAS.

Brainstem Evoked Potentials

Brainstem evoked potentials (BSEP) were recorded in 23 patients with adult sleep apnea (ASA). These patients were studied with all-night polysomnography prior to our testing. They were categorized as having obstructive, central, or mixed sleep apnea depending on the predominant sleep findings. All patients with central sleep apnea had abnormal BSEP with prolongation of wave V. A majority of the remaining patients with obstructive sleep apnea and mixed sleep apnea had abnormal BSEP, but without specific configurations. These findings substantiate our hypothesis that brainstem dysfunction may play a role in ASA.

Abstract Introduction The apnea-hypopnea index (AHI) is used as a generic index to quantify both central sleep apnea (CSA) and obstructive sleep apnea (OSA) syndromes. Patterns of oxygenation abnormalities seen in CSA and OSA may be key to understanding differing clinical impacts of these disorders. Oxygen desaturation and resaturation slopes and durations in OSA and CSA were compared between OSA and CSA patients. Methods Polysomnographic data of patients aged 18 years or older with diagnosis of OSA and CSA, at University of Iowa Hospitals and Clinics, were analyzed and demographic data were collected. Oximetric changes during hypopneas and apneas were studied for desaturation/resaturation durations and desaturation/resaturation slopes. Desaturation and resaturation slopes were calculated as rate of change in oxygen saturation (ΔSpO2/Δtime). Comparison of hypoxemia-based parameters between patients with OSA and CSA was performed using unpaired t-test. Results 32 patients with OSA with median AHI of 15.4 (IQR 5.1 to 30.55) and median ODI of 15.47 (IQR 9.50 to 29.33) were compared to 15 patients with CSA with a median AHI of 20.4 (IQR 12.6 to 47.8) and median ODI of 27.56 (IQR 17.99 to 29.57). The mean number of desaturation and resaturation events was not significantly different between patients with OSA and CSA (OSA - 106.81±87.93; CSA - 130.67±76.88 with a p-value 0.1472). 4/15 CSA patients had Cheyne-Stokes breathing, 2/15 had treatment emergent central sleep apnea, 1/15 had methadone-associated CSA and for 8/15, no etiologies for CSA were found. Mean desaturation durations was significantly longer in OSA (20.84 s ± 5.67) compared to CSA (15.94 s ± 4.54) (p=0.0053) and consequently the desaturation slopes were steeper in CSA than OSA (-0.35%/sec ±0.180 vs. -0.243 ± 0.073; p=0.0064). The resaturation duration was not significantly longer in OSA (9.76 s ± 2.02) than CSA (9.057 s ± 2.17) (p=0.2857). Differences between desaturation duration and slopes between CSA and OSA persisted during REM and NREM sleep, and in supine sleep. Conclusion As compared to OSA, patients with CSA have different patterns of desaturations and resaturations with lesser hypoxic burden with CSA. This may have implications on the clinical outcomes seen between these two disorders. Support (if any):

Obstructive Sleep

This review summarizes recent literature addressing the association of short sleep duration, shift work, and obstructive sleep apnea with hypertension risk, blood pressure (BP) levels, and 24-hour ambulatory BP. Observational studies demonstrate that subjectively assessed short sleep increases hypertension risk, though conflicting results are observed in studies of objectively assessed short sleep. Intervention studies demonstrate that mild and severe sleep restriction are associated with higher BP. Rotating and night shift work are associated with hypertension as shift work may exacerbate the detrimental impact of short sleep on BP. Further, studies demonstrate that shift work may increase nighttime BP and reduce BP control in patients with hypertension. Finally, moderate to severe obstructive sleep apnea is associated with hypertension, particularly resistant hypertension. Obstructive sleep apnea is also associated with abnormal 24-hour ambulatory BP profiles, including higher daytime and nighttime BP, nondipping BP, and a higher morning surge. Continuous positive airway pressure treatment may lower BP and improve BP dipping. In conclusion, efforts should be made to educate patients and health care providers about the importance of identifying and treating sleep disturbances for hypertension prevention and management. Empirically supported sleep health interventions represent a critical next step to advance this research area and establish causality.
