Interstitial pneumonitis and pulmonary vasculitis in a patient taking an L-tryptophan preparation.

A case is presented of interstitial pneumonitis and pulmonary vasculitis ascribed to the ingestion of an L-tryptophan preparation. An unintended rechallenge supported the causal relationship. There was neither myalgia nor peripheral eosinophilia. Bronchoalveolar lavage fluid contained 12% eosinophils but few were present in the surgical lung biopsy specimen. Lung infiltrates receded after withdrawal of the drug and treatment with steroids. Dyspnoea and pulmonary hypertension persisted. Cyclophosphamide had no effect. Sclerodermiform skin lesions appeared as a late sequel. Chromatographic analysis of the L-tryptophan revealed no suspect impurities.

Role of gallium 67 thoracic scintigraphy in the diagnosis and staging of patients suspected of bronchial carcinoma.

Gallium 67 (67Ga) lung scanning was performed in 100 consecutive cases in which because of the history, clinical data, or abnormal radiological findings, a bronchial carcinoma was suspected. This study allows the conclusion that a negative as well as a positive scan is an important element in the diagnosis of some cases of bronchial carcinoma. The method is most helpful in the preoperative diagnosis of circumscribed peripheral shadows and in the assessment of suspected hilar enlargement; it may even visualise hidden malignant tumours. Gallium 67 scanning is also valuable in the assessment of hilar and mediastinal involvement in the presence of a proven primary lung tumour. This study supports the view that in the presence of a negative mediastinal scan the patient may be spared mediastinoscopy and be referred directly for operation.
