We aimed to evaluate children with chronic cough following a standardized cough algorithm and assess obstructive sleep apnea (OSA) as a possible etiology. In addition, cough resolution rates of two different treatment protocols in children with non-specific cough were compared.

Alternative technique to transfer jaw relations for custom mandibular advancement devices: A case report.

Oral appliance therapy for obstructive sleep apnea can be helpful in mild and moderate cases. This clinical report evaluates the efficacy of a protocol that predicts an optimal jaw position and describes the response of a young OSA patient to treatment.

Comparison of full-night and ambulatory polysomnography with ApneaGraph in the subjects with obstructive sleep apnea syndrome.

The localization of the obstruction is crucial in determining the appropriate surgical treatment for obstructive sleep apnea syndrome (OSAS); ApneaGraph has been introduced for diagnosis of OSAS and localization of airway obstruction level. This study aims to evaluate the diagnostic value of ApneaGraph for both clinical staging and site of obstruction. Thirty male OSAS patients were prospectively enrolled in this clinical trial.

The prevalence of obstructive sleep apnea in patients with difficult-to-treat asthma.

Objectives: Obstructive sleep apnea (OSA) occurs more commonly in asthma patients than in the general population and can complicate asthma management. The aim of this study was to evaluate the presence of OSA in patients with difficult-to-treat asthma (DTA) and to investigate the sleep quality in these patients.

Methods: Patients with DTA were recruited from the adult allergy clinic of a tertiary care hospital.

The efficacy of Watch PAT in obstructive sleep apnea syndrome diagnosis.

Polysomnography is currently considered as the gold standard for the diagnosis of obstructive sleep apnea syndrome (OSAS). But high expense and the backlog of the sleep centers have resulted in a search for an alternative method of diagnosis. The aim of this study is to assess the efficacy and reliability of Watch PAT as an alternate option in OSAS diagnosis.

Management of obstructive sleep apnea in an edentulous lower jaw patient with a mandibular advancement device.

Obstructive sleep apnea (OSA) is the most common sleep-related breathing disorder with periodic reduction or cessation of airflow during sleep. It is associated with loud snoring, disrupted sleep, and witnessed apneas. Treatment of OSA varies from simple measures such as oral appliances and nasal continuous positive airway pressure (CPAP) to surgical procedures like uvulopalatopharyngoplasty and tracheostomy.

Relationship between obstructive sleep apnea syndrome and thyroid diseases.

Obstructive sleep apnea syndrome (OSAS) is a widespread disorder characterized by recurrent, partial, or complete episodes of apnea due to upper airway tract obstruction during sleep. OSAS frequency is likely to increase in hypothyroidism because of obesity, macroglossia, dysfunctional upper respiratory tractus (URT) musculature, deposition of mucopolysaccharides in URT tissues, and decreased ventilatory control. This study examines the relationship between OSAS and thyroid disease in OSAS subjects.
