Hypersensitivity pneumonitis in a technician using Pauli's reagent.
A technician working in a medical laboratory used a spray of sodium diazobenzenesulphate (Pauli's reagent) in chromatography. She developed a respiratory illness with both airways obstruction and radiographic and physiological evidence of interstitial pneumonitis. An occupational type of challenge test was followed by both immediate and late bronchial obstructive responses, by a fall in arterial oxygen tension, and by increased radiographic shadowing. Histology of a lung biopsy specimen, a low serum C3, and a postive skin prick test to the reagent suggested that the illness was a hypersensitivity reaction to Pauli's reagent.

Pulmonary function in Bechçet's syndrome.
Pulmonary function in Behçet's syndrome has not received much attention, although sporadic cases of airways obstruction have been described. In this series of five cases one had abnormal results with reversible airways obstruction and emphysema. These findings were likely to have been associated with asthma, previous smoking habits and pulmonary tuberculosis, and not another manifestation of Behçet's syndrome.

Reversibility of airways obstruction in bronchiectasis.
Patients with airways obstruction and bronchiectasis were investigated for features of allergic disease and for reversibility of airways obstruction in respinse to inhaled and intravenous salbutamol. There was a 26% increase in PEFR and a 16% increase in FEV1 after inhaled salbutamol, and the response to the intravenous drug was not significantly better than that to the inhaled. Those patients who responded to bronchodilators could not be identified by clinical or immunological features.
