We describe the development of severe and recurrent alveolar hemorrhage in a 30 year old man. The patient had presented with frank hemoptysis, that recurred after an interval of 4 weeks, associated with dyspnea and severe anemia requiring transfusion. The chest x-ray and CT scan showed bilateral diffuse ground glass shadows. Fibreoptic bronchoscopy confirmed bilateral diffuse bleeding. Investigations for the common causes of diffuse alveolar hemorrhage (immunological, infective) proved to be negative on two occasions. Toxicological examination of the urine during the relapse revealed a significant level of cannabis and a trace of cocaine. The patient repeatedly denied the use of illicit drugs. ⋯ This clinical observation emphasises that the inhalation of cocaine is a cause of diffuse alveolar hemorrhage particularly in young adults.

We report the case of a young woman presenting with dyspnoea of effort. Her records noted that correction of a double aortic arch had been performed in the neonatal period. At rest her flow/volume loop showed a moderate reduction of peak flow without an expiratory plateau. Exercise capacity was limited by sudden onset, during the last 2 stages of the test, of inspiratory dyspnea and tachypnea. During recovery there was no evidence of bronchospasm. ⋯ We have thus demonstrated that the increase in tracheal compression leading to limitation of airflow on exercise was due to an increase in aortic pressure and not to an increase in ventilatory flows.
