Sleep & breathing = Schlaf & Atmung

Descriptions of nocturnal vocalizations, including catathrenia, are few. We undertook a study at our center on patients diagnosed with catathrenia, to evaluate the characteristic features of these events and their response to continuous positive airway pressure (CPAP) treatment. ⋯ New and unique features were identified in our series of patients diagnosed with catathrenia. Though all events had the characteristic moaning and groaning sound during exhalation, only a small percentage (5%) met the catathrenia definition as outlined in ICSD-2. Do we label the atypical events as part of the spectrum of nocturnal vocalizations or consider them as catathrenia by redefining the criteria? CPAP appeared to be a reasonable treatment option.

The purpose of this study was to evaluate the prevalence and assess the response to nasal automatic positive airway pressure (APAP) therapy of less typical symptoms in patients diagnosed with obstructive sleep apnea (OSA), like fatigue, gasping, nocturia, nocturnal sweating, morning headaches, heartburn, and erectile dysfunction. ⋯ The findings suggest that APAP therapy is effective in controlling the majority of OSA symptoms beyond sleepiness and snoring.

Although continuous positive airway pressure (CPAP) is the gold standard in the treatment of obstructive sleep apnea (OSA), its effectiveness depends on the regular use. In this retrospective study, the effectiveness of CPAP with regard to the reduction of the apnea-hypopnea index was calculated based on individual adherence data extracted from a cohort of patients with OSA METHODS: The electronic database was analyzed for follow-up visits of patients receiving CPAP for OSA. The following information was extracted the charts of 750 patients: apnea-hypopnea index (AHI) at diagnosis, AHI with CPAP, duration of therapy, hours of CPAP use, and subjective hours of sleep. Eighty-two successfully treated and stable CPAP patients (AHI/Epworth Sleepiness Scale (ESS) at baseline 35.6 ± 22.1/10.5 ± 5.1) could be further evaluated. ⋯ Even in an ideal group of patients, CPAP cannot eliminate respiratory events due to limited adherence. Adherence needs to be taken into account when comparing the effects of CPAP on the AHI with alternative treatment methods, especially those with 100% adherence (e.g., surgery).

Medical school surveys of pre-doctoral curriculum hours in the somnology, the study of sleep, and its application in sleep medicine/sleep disorders (SM) show slow progress. Limited information is available regarding dentist training. This study assessed current pre-doctoral dental education in the field of somnology with the hypothesis that increased curriculum hours are being devoted to SM but that competencies are still lacking. ⋯ Results showed 75.5% of responding US dental schools reported some teaching time in SM in their pre-doctoral dental program with curriculum hours ranging from 0 to 15 h: 12 schools spent 0 h (24.5%), 26 schools 1-3 h, 5 schools 4-6 h, 3 schools 7-10 h, and 3 schools >10 h. The average number of educational hours was 3.92 h for the schools with curriculum time in SM, (2.96 across all 49 responding schools). The most frequently covered topics included sleep-related breathing disorders (32 schools) and sleep bruxism (31 schools). Although 3.92 h is an improvement from the mean 2.5 h last reported, the absolute number of curriculum hours given the epidemic scope of sleep problems still appears insufficient in most schools to achieve any competency in screening for SRBD, or sufficient foundation for future involvement in treatment.

In the clinical practice of sleep medicine, the coexistence of common sleep disorders is not uncommon. Patients with sleep disordered breathing (SDB) may present with insomnia, and studies have shown that SDB is common among insomnia patients. Little is known about the pathophysiological mechanisms underlying this coexistence, and limited information is available regarding the impact of each disorder on the other. It is essential to consider the effect of each disorder on the other and to understand the clinical consequences anticipated when treating each disorder in isolation. The management plan should be directed toward both disorders in a systematic and evidence-based approach. Unfortunately, a consensus standard approach for the management of comorbid insomnia and SDB is not yet available. ⋯ Therefore, we have reviewed published studies that investigated insomnia in patients with different types of SBD; obstructive sleep apnea, central sleep apnea, and hypoventilation syndromes, as well as studies that assessed SBD in patients with insomnia. In addition, we reviewed the effects of SBD treatment modalities on insomnia and the effects of insomnia treatments on SBD.
