The diagnosis of sarcoidosis is made by the combination of clinical features and biopsy results. The clinical features of sarcoidosis can be quite variable. We developed a Sarcoidosis Diagnostic Score (SDS) to summarize the clinical features of patients with possible sarcoidosis. ⋯ For sarcoidosis, the presence of specific clinical features, especially multiorgan involvement, can enhance the diagnostic certainty. The SDS scoring system quantitated the clinical features consistent with sarcoidosis.

The pathophysiologic mechanism of nocturnal obstruction and swallowing dysfunction commonly occurring in patients with sleep apnea is unclear. The goal of this study was to investigate whether nerve injuries in the upper airways of snorers and patients with sleep apnea are associated with pharyngeal dysfunction and severity of sleep apnea. ⋯ Axon degeneration in preterminal nerves of the soft palate is associated with pharyngeal dysfunction in snorers and patients with sleep apnea. The most likely cause for the nerve injuries is traumatic snoring vibrations and tissue stretch, leading to swallowing dysfunction and increased risk for upper airway obstruction during sleep.

A 67-year-old retired air force officer presented with a 6-month history of nonproductive cough, progressive exertional dyspnea, and weight loss. He was unable to walk beyond 100 m compared with his baseline of unlimited walking distance. ⋯ Joint involvement had previously been controlled with methotrexate, which was discontinued 15 years ago after resolution of his symptoms. He developed a polyarthritis flare a year ago, and adalimumab was initiated with good response.
