Studies using sleep diaries have shown a delay in bedtime and rise time during Ramadan. However, no objective study has assessed sleep pattern during Ramadan in a free living environment...

Very limited number of studies has addressed cardiac arrhythmias in OSA patients. Objectives: To estimate the prevalence and types of arrhythmias in OSA patients and to try to detect predictors for arrhythmia in this group of patients...

Previous studies have reported conflicting results with regard to thyroid disease in obstructive sleep apnea (OSA) patients. Objectives: To determine the prevalence and predictors of thyroid disease in OSA patients...

Obstructive sleep-disordered breathing consists of a spectrum ranging from the upper airway resistance syndrome to complete apnea. Although this disorder is relatively common, it is still under-recognized, resulting in a significant increase in morbidity and mortality...

Cardiovascular diseases are more common in patients with obstructive sleep apnea (OSA) than in the general population. We hypothesized that severe hypoxemia during sleep in these patients may cause an imbalance between reactive oxygen species and the antioxidant reserve that is important for the detoxification of these molecules...

Although gastric aspirates (GA) are one of the recommended screening procedures for asymptomatic individuals at high risk for developing tuberculosis (TB), little data exist on the utility of GA for this indication...

To determine the validity of acid-fast (AFB) smears of gastric aspirates (GA) in the diagnosis of pulmonary tuberculosis, and to assess the prevalence of nontuberculous mycobacteria (NTM) in GA isolates from such patients...

The patient's condition did not improve and he developed anorexia, progressive weight loss, progressive dyspnea, dry cough, lower limb swelling, and right-sided abdominal pain. He was referred to our hospital for further management six weeks after his initial presentation....

Obstructive sleep apnea syndrome (OSAS) patients may have symptoms for years prior to recognition of their disorder, or they may be treated for the associated comorbidities. We hypothesized that such patients would be heavy consumers of health care resources for several years prior to diagnosis...
