This paper examines the incidence of cavitation among tumours of the lung, the various radiological appearances and cellular types of these cavitated tumours, and the resulted of sputum cytology. Over a 46 months' period, histological and or cytological evidence of pulmonary neoplasm was found in 244 subjects whose posteroanterior chest radiographs showed opacities suggestive of pulmonary malignant disease. Of the 244 lung tumours, 220 (90%) were primary and 24 (10%) were secondary. ⋯ Surprisingly, the finding of cancer cells in the sputum was no more frequent in cavitated tumours than in solid tumours. It is concluded that if a cavitated lesion in the radiograph is maglinant, a primary squamous cell carcinoma of the lung is the most likely cause. Sputum cytology performed by a competent cytologist is a very useful and simple diagnostic tool, but it appears to be no more helpful in diagnosing cavitated than in solid lung cancers.

The Waikato Hospital experience of women admitted or seen in the Cardiology Outpatient Clinic who were under the age of 40 and whose diagnosis was a recent acute coronary occlusive episode was reviewed. It was found that there were nine admissions in eight women in this category between December 1971 and November 1973, plus one further patient who was seen with a recent acute ischaemic episode as an outpatient. The histories of these patients were reviewed and their risk factors surveyed. ⋯ As opposed to previous studies, not all the women in this study showed risk factors other than oral contraceptive usage. Three patients in this group taking oral contraceptives and who were thought to have definite coronary ischaemic episodes had no other major risk factor though two of the three were obese. It is thought probable that oral contraceptives containing oestrogens should be considered as a coronary risk factor in young women.
