Obstructive sleep apnea in patients with severe asthma: Prevalence and association between severity and asthma control.

Introduction: Asthma and obstructive sleep apnea (OSA) are common respiratory disorders that can coexist and cause sleep disturbances. The strength of this association and the impact of OSA on asthma severity and control remain unclear. The study aims to estimate the prevalence of OSA in patients with severe asthma in Oman and to examine whether the severity of OSA contributed to the level of asthma control.

Pulmonary infarction mimicking a lung mass: a case report.

Pulmonary infarction usually appears as a wedge-shaped opacity with its base placed laterally. Rarely, pulmonary infarctions may appear as a well-defined rounded opacity mimicking lung cancer and surgical lung biopsy may often be required for definitive diagnosis. We report a patient who was admitted with submassive pulmonary embolism who had an incidental finding of a well-defined opacity in computed tomography (CT) scan.

Hypercalcaemia: A portent of sarcoidosis in cystic fibrosis.

The coexistence of cystic fibrosis (CF) and sarcoidosis is rare. We report a 22-year-old male cystic fibrosis patient who presented multiple times to the Sultan Qaboos University Hospital, Muscat, Oman, in 2013. He was diagnosed with non-parathyroid-related hypercalcaemia and anterior uveitis, while computed tomography revealed mediastinal and abdominal lymphadenopathy and mild hepatosplenomegaly.
