2.  Risk factors for myocardial infarction in young women. 
Seventy-seven women discharged from hospital with a diagnosis of myocardial infarction and 207 control patients were investigated. All were under 45 years of age at the time of admission. Heavy cigarette smoking, reported treatment for pre-eclamptic toxaemia, and type II hyperlipoproteinaemia were found to be independent risk factors for myocardial infarction. Reported treatment for hypertension and diabetes are probably also independently associated with subsequent development of the condition, but the associations between myocardial infarction and reported treatment for obesity and psychiatric illness appear to be secondary. Previous publications have suggested that use of oral contraceptives is an independent risk factor. Examination of the effect of several factors combined, suggests that they act synergistically, the presence of three or more factors increasing the risk 128-fold.

3.  Migraine in general practitioners. 
A self-administerd questionnaire was posted to 1 129 medical general practitioners in an urban and in a rural area of England. The prevalences of headache, and of the features of migraine, in the year immediately preceding the survey were similar in the two areas. After allowing for the different age and sex composition of the populations, these prevalences were also similar to those found in the general population during an early survey in Wales. About 13% of the male and 25% of the female general practitioners thought that they had had migraine in the previous year. There was little evidence that doctors with 'classic' migraine differed from those with 'common' migraine in the proportion who experienced other migrainous features (unilateral distribution of headache and accompanying nausea) or in their response to treatment with ergotamine.
