The organisation of on-site medical personnel and facilities is described for an open air rock concert attended by 62,000 people. Care of the majority of patients was completed on site, avoiding an increased workload for local hospitals and general practitioners. Many of the head injuries could have been avoided by preventing the distribution of promotional items and large drinks containers which were thrown as missiles.
The hypothesis that negative affectivity (NA) is associated with accuracy of blood glucose (BG) symptom perceptions and diabetes control was assessed. After completing measures of BG symptom beliefs and NA-related constructs (i.e., attentional focus and trait anxiety), 35 adolescents with insulin-dependent diabetes monitored their physical symptoms and their actual BG levels 3 times daily for 2 weeks. Each subject's actual BG symptoms were determined by correlating symptom ratings with BG levels and were then compared with symptom beliefs. Those who were more internally focused were more able to discern which symptoms actually covaried with BG fluctuations; those with higher trait anxiety tended to misattribute non-diabetes-related symptoms to BG levels. Finally, interactions suggested that those who both attend to internal physical sensations and experience-heightened anxiety display poorer metabolic control.

STUDY OBJECTIVE: The aim was to test the assumption that mass miniature x ray screening of the single homeless (hostel residents) is a cost-effective means of controlling pulmonary tuberculosis. DESIGN: The study was a prospective experimental screening exercise to identify new cases of active tuberculosis completing treatment. SETTING: The setting was eight hostels in south London. A mobile x ray screening facility was set up outside the hostels. SUBJECTS: Subjects were 547 single homeless residents in the hostels. They were encouraged to attend for chest x ray, and for active follow up of abnormal x rays. MAIN RESULTS: No new cases of active tuberculosis were found. CONCLUSIONS: Mass miniature x ray is ineffective in controlling tuberculosis because of its unacceptability and increasing inaccessibility to this population.

The effects of a high-carbohydrate, high-fiber (HCHF) diet on glucose control was evaluated in 12 children with type I diabetes mellitus. The children had had diabetes for an average of 5.25 yr; their mean glycosylated hemoglobin was 12.4% (normal 5-9%), and C-peptide was virtually undetectable in all but one. They were followed on a regular diabetic diet for 10 days at home and in the hospital and then were studied on a HCHF diet for 14 days. The HCHF diet contained 60% carbohydrate and 30 g of fiber per 1000 cal provided through grains, fruits, vegetables, and high-fiber crackers. Capillary blood glucose levels were monitored at home before meals and at bedtime, and venous plasma glucose levels were measured in the hospital before and after each meal and during the night. Plasma glucose was measured serially after test meals with each diet. There was no significant difference in blood glucose levels preprandially, postprandially, and while fasting on the two diets. The 24-h glucose profiles and posttest meal profiles obtained during both diets were remarkably similar. We conclude that a diet high in fiber and carbohydrate has limited application in children with type I diabetes mellitus who have no residual beta-cell function.
