We describe the case of a woman who had been referred to us with a history of breathing difficulties and snoring and a suspicion of obstructive sleep apnea (OSA). Our investigation revealed that she did indeed have severe OSA in addition to undiagnosed bilateral vocal fold paralysis of unknown origin. Nocturnal polysomnography found that her apnea/hypopnea index was 120 and her minimum arterial oxygen saturation level was 63%. She was treated with laterofixation of the right vocal fold, and her OSA resolved immediately. During 10 years of follow-up with nocturnal polysomnography, no recurrence of apnea or low oxygen saturation levels was noted. However, she did experience a recurrence of her snoring 4 years postoperatively, along with the onset of progressively worsening daytime fatigue. When these conditions persisted, we performed a repeat laterofixation of the same vocal fold. Following the repeat surgery, subjectively and objectively assessed results were good.

Background Obstructive sleep apnea (OSA) in children is often associated with recurrent hypoxemia during sleep. In developing animals, central opioid neuropeptide content is high, and opioid receptors are up-regulated after recurrent hypoxia. The authors hypothesized that children with recurrent hypoxemia due to OSA might have altered central opioid functionality that could affect their responsiveness to opioid drugs. Using a retrospective database, we assessed the relation of age and preoperative oxygen saturation to the cumulative postoperative morphine dose administered for analgesia in children with OSA undergoing adenotonsillectomy. Methods Inclusion criteria were (1) adenotonsillectomy for OSA; (2) no concomitant pathology; (3) intraoperative administration of short-acting opioid drugs; (4) endotracheal extubation on awakening in the operating room; and (5) morphine as the parenteral, postoperative analgesic. Results Forty-six children (16 girls) fulfilled the inclusion criteria. Age and preoperative arterial oxygen saturation (SaO2) nadir, either individually (P = 0.023, P = 0.0003, respectively) or in combination (P = 0.00009), exhibited a significant correlation to the morphine dose required for analgesia. Four of these children, aged 26.5 +/- 13.2 months, with a preoperative SaO2 nadir of 70.3 +/- 12.9%, did not require any postoperative morphine for analgesia at all. Conclusions The authors speculate that the reduced morphine requirement for analgesia in children displaying oxygen desaturation associated with severe OSA may be related to their young age and to an up-regulation of central opioid receptors consequent to recurrent hypoxemia. In evaluating OSA in children, preoperative determination of the SaO2 nadir is important for predicting the postoperative opioid dosage required for analgesia.

Untreated obstructive sleep apnea (OSA) has numerous negative health-related consequences. Continuous positive airway pressure (CPAP) is generally considered the treatment of choice for OSA, but rates of nonadherence are high. It is believed that OSA is more prevalent among men; therefore understanding how OSA presents among women is limited and treatment adherence has received little research attention. For this study, 29 women were recruited from primary care offices. They completed a questionnaire battery and underwent a night of nocturnal polysomnography (PSG) followed by a visit with a sleep specialist. Women diagnosed with OSA were prescribed CPAP; 2 years later CPAP adherence was evaluated. Results show that approximately half the sample was adherent. There were no significant differences between adherent and nonadherent women on OSA severity; however CPAP adherent women had worse nocturnal and daytime functioning scores at the time of diagnosis. Moreover, when the seven nocturnal and daytime variables were used as predictors in a discriminant analysis, they could predict 87% of adherent and 93% of the nonadherent women. The single most important predictor was nonrefreshing sleep. We discuss the implications of the findings for identifying women in primary care with potential OSA and offer suggestions for enhancing treatment adherence.

Background: Severe obstructive sleep apnea (OSA), defined by apnea-hypopnea index (AHI) as more than 30 events per hour, was previously related to more comorbidity. However, limited studies separated the patients with AHI > 100 from those with a less severe manifestation of the disease. Objectives: The current study aimed at describing the characteristics of this subgroup and comparing them with less severe conditions. Methods: A retrospective analysis was conducted on 114 patients with OSA. Nocturnal polysomnography was used to diagnose severe OSA. Patients were categorized into two groups: (1) 60 < AHI < 100 (very severe OSA), (2) AHI ≥ 100 (extreme OSA). Demographic, medical history, and polysomnographic variables were evaluated and compared between the two groups. Results: Extreme OSA was diagnosed in 19 patients, the mean body mass index (BMI) was significantly higher in this group (39.26 ± 5.93 vs. 35.68 ± 6.45 kg/m2, P = 0.025). They also had lower minimal O2 saturation (65.68 ± 10.16 vs. 74.10 ± 8.74, P = 0.003) and more time with < 90% O2 saturation (T < 90%) (81.78 ± 22.57 vs. 58.87 ± 33.14, P = 0.01). OHS prevalence was significantly higher in the group with extreme OSA (P = 0.04). The most frequent comorbidity was hypertension, with an incidence of 60.5%, for the extreme group, although there was no significant difference between the two groups in terms of clinical associations. Conclusions: The current study results suggested that greater BMI and lower minimal O2 saturation, as well as increased T < 90%, were associated with extreme OSA, although no differences were observed in the associated diseases between the compared groups.

Children with Down syndrome have many predisposing factors for the obstructive sleep apnea syndrome (OSAS), yet the type and severity of OSAS in this population has not been characterized. Fifty-three subjects with Down syndrome (mean age 7.4 ± 1.2 [SE] years; range 2 weeks to 51 years) were studied. Chest wall movement, heart rate, electrooculogram, end-tidal Po2 and Pco2, transcutaneous Po2 and Pco2, and arterial oxygen saturation were measured during a daytime nap polysomnogram. Sixteen of these children also underwent overnight polysomnography. Nap polysomnograms were abnormal in 77% of children; 45% had obstructive sleep apnea (OSA), 4% had central apnea, and 6% had mixed apneas; 66% had hypoventilation (end-tidal Pco2, &gt;45 mm Hg) and 32% desaturation (arterial oxygen saturation &lt;90%). Overnight studies were abnormal in 100% of children, with OSA in 63%, hypoventilation in 81%, and desaturation in 56%. Nap studies significantly underestimated the presence of abnormalities when compared to overnight polysomnograms. Seventeen (32%) of the children were referred for testing because OSAS was clinically suspected, but there was no clinical suspicion of OSAS in 36 (68%) children. Neither age, obesity, nor the presence of congenital heart disease affected the incidence of OSA, desaturation, or hypoventilation. Polysomnograms improved in all 8 children who underwent tonsilletomy and adenoidectomy, but they normalized in only 3. It is concluded that children with Down syndrome frequently have OSAS, with OSA, hypoxemia, and hypoventilation. Obstructive sleep apnea syndrome is seen frequently in those children in whom it is not clinically suspected. It is speculated that OSAS may contribute to the unexplained pulmonary hypertension seen in children with Down syndrome.

Continuous Positive Pressure

The effect of nasal continuous positive pressure (CPAP) treatment on erythropoietin (EPO) was examined by measuring diurnal serum EPO levels before and twice (over the 3rd day and over 1 day on recall after > or = 1 mo of therapy) after initiation of treatment in 12 obstructive sleep apnea syndrome patients with normal hemoglobin, hematocrit, creatinine, blood urea nitrogen, and albumin levels. Over each study day, oxygen saturation was measured by an ambulatory pulse oximetry system. Patients spent 27 +/- 9% (SE) of time below oxygen saturation of 88% vs. 2.1 +/- 0.6% after initiation of nasal CPAP treatment (P < 0.01). The number of desaturation events per hour of sleep before nasal CPAP treatment was 62 +/- 6 vs. 9 +/- 2 with nasal CPAP (P < 0.01). EPO levels measured by radioimmunoassay were drawn every hour before and at 3 days (n = 9) and before and at recall (n = 0) after initiation of CPAP therapy. The mean serum EPO level was higher before treatment (61 +/- 14 mU/ml) than that at 3 days (38 +/- 10 mU/ml, P < 0.01) or at recall (32 +/- 7 mU/ml, P < 0.01). We conclude that nasal CPAP treatment of sleep-disordered breathing will reduce diurnal levels of EPO.

Objective To examine outcomes in the intermediate term (1 to <4 years), long term (4 to <8 years), and very long term (≥8 years) for maxillomandibular advancement (MMA) as treatment for obstructive sleep apnea (OSA). Data Sources The Cochrane Library, Google Scholar, Embase, Cumulative Index to Nursing and Allied Health, and PubMed/MEDLINE. Review Methods Three authors systematically reviewed the international literature through July 26, 2018. Results A total of 445 studies were screened, and 6 met criteria (120 patients). Thirty-one patients showed a reduction in apnea-hypopnea index (AHI) from a mean 48.3 events/h (95% CI, 42.1-54.5) pre-MMA to 8.4 (95% CI 5.6, 11.2) in the intermediate term. Fifty-four patients showed a reduction in AHI from a mean 65.8 events/h (95% CI, 58.8-72.8) pre-MMA to 7.7 (95% CI 5.9, 9.5) in the long term. Thirty-five showed a reduction in AHI from a mean 53.2 events/h (95% CI 45, 61.4) pre-MMA to 23.1 (95% CI 16.3, 29.9) in the very long term. Improvement in sleepiness was maintained at all follow-up periods. Lowest oxygen saturation improvement was maintained in the long term. Conclusion The current international literature shows that patients with OSA who were treated with MMA maintained improvements in AHI, sleepiness, and lowest oxygen saturation in the long term; however, the mean AHI increased to moderate OSA in the very long term. Definitive generalizations cannot be made, and additional research providing individual patient data for the intermediate term, long term, and very long term is needed.
