A 66-year-old male nonsmoker from Arizona was referred to our practice for evaluation of chronic cough. He had a history of biopsy-proven relapsing polychondritis manifesting as right auricular and nasal pain and swelling 9 months prior to presentation. The onset of his cough coincided with the diagnosis of relapsing polychondritis, and he was prescribed prednisone 90 mg/d, which promptly relieved his rheumatologic and respiratory symptoms. ⋯ A second chest radiograph done 6 months before presentation, while the patient was receiving prednisone 20 mg/d, was normal as well. In anticipation of our evaluation, he stopped all glucocorticoids for 7 days. He was not receiving any other medications, and he had no history of an atopic diathesis.

A 34-year-old woman presented with her third episode of acute-onset right-sided chest pain and dyspnea. She had two prior similar occurrences of right-sided sharp, pleuritic chest pain with radiation to the back and dyspnea. ⋯ She denied cough, hemoptysis, fever, smoking history, airplane travel, scuba diving, or trauma during these presentations. The patient has been trying to conceive for the past year but has been unsuccessful because of uterine fibroids but no history of endometriosis.

A 21-year-old woman with cystic fibrosis (CF) was seen in the pulmonary clinic complaining of abdominal pain. Her past medical history included bilateral lung transplantation for CF pulmonary disease 26 months previously, as well as gastroesophageal reflux disease and pancreatic insufficiency. Her baseline weight was 49.1 kg (BMI, 19.4 kg/m2).

The intensity of cough is an important determinant of cough severity. Few studies have quantified cough intensity in patients with chronic cough with objective measures. We investigated the intensity of voluntary, induced, and spontaneous cough in patients with chronic cough and healthy control subjects. ⋯ Maximum voluntary cough intensity was increased in patients with chronic cough compared with control subjects. There was no significant difference in expiratory muscle contractility. Further studies should evaluate the compressive phase of cough in more detail. Physiologic measures of cough intensity correlated strongly with subjective perception of intensity in patients with chronic cough and may be relevant objective outcome measures for clinical studies.
