Occupational asthma due to methyl methacrylate and cyanoacrylates.

Five patients had asthma provoked by cyanoacrylates and one by methyl methacrylate, possibly because of the development of a specific hypersensitivity response. Acrylates have wide domestic as well as industrial uses, and inhalation of vapour emitted during their use can cause asthma.

Sedation for endoscopy: a comparison between diazepam, and diazepam plus pethidine with naloxone reversal.

The combination of diazepam plus pethidine, reversed with naloxone, was compared in a double-blind randomized study with diazepam alone in 100 patients undergoing endoscopy. Patients accepted both methods of sedation equally well. There was no significant difference in sedation after endoscopy, but the addition of pethidine produced a significant improvement in patient co-operation during the endoscopy (P less than 0.001).

Bronchoscopic and percutaneous aspiration biopsy in the diagnosis of bronchial carcinoma cell type.

The cell type of bronchial carcinoma predicted from the results of bronchial biopsy at fibreoptic or rigid bronchoscopy or of percutaneous aspiration lung biopsy was compared with the type determined by histological examination of specimens obtained by thoracotomy, biopsy of an extrapulmonary metastasis, or necropsy in 180 cases. The rates of agreement with the final diagnosis were 95.7% for bronchial biopsy through the fibreoptic bronchoscope and 86.5% through the rigid bronchoscope. For percutaneous biopsy, which was usually carried out on tumours inaccessible to the bronchoscope, the rate of agreement was 61%, significantly lower than by the other methods (p less than 0.001). The diagnosis of oat-cell carcinoma by any technique was very reliable. Bronchial biopsy was more reliable than was percutaneous biopsy in diagnosing squamous-cell carcinoma. With any technique the commonest error was the incorrect diagnosis of squamous-cell carcinoma or adenocarcinoma as large-cell undifferentiated carcinoma.
