ABSTRACT
Hospital-based specialist registrars in Nottingham are offered six month secondments in public health medicine. These attachments give clinicians valuable skills in public health and an opportunity to influence the development of local health service provision. Other skills gained are an understanding of the balance between health promotion and disease treatment; the management of limited resources; an appreciation of the effects of social deprivation; the chairing and preparing of committee meetings; and contact tracing of communicable diseases. We strongly recommend the experience gained from working in a lively public health department.

AIMS: Vascular endothelial dysfunction, an early marker of atherosclerosis, has been demonstrated in Type 2 diabetes mellitus (DM). Vitamin E preserves endothelial function in animal models of diabetes and reduces cardiovascular risk. We examined endothelial function and the effect of vitamin E supplements in uncomplicated Type 2 DM. METHODS: Forty-eight subjects with Type 2 DM and 21 controls had endothelial function assessed using forearm venous occlusion plethysmography with endothelium-independent (sodium nitroprusside) and dependent (acetylcholine, bradykinin) vasodilators. Those with diabetes received 1600 i.u. daily oral alpha-tocopherol or placebo, double-blind for 8 weeks, and had endothelial function reassessed. RESULTS: The diabetic group had higher HbA1c (6.9+/-1.4 vs 4.8+/-0.6%; P<0.01) and systolic (145+/-15 vs. 130+/-16 mm Hg; P<0.01) but not diastolic blood pressure (79+/-8 vs. 76+/-9 mm Hg; P = 0.15). There was blunted vasodilation to acetylcholine (15 microg/min; P<0.01) in subjects with diabetes. Vasodilation to sodium nitroprusside and bradykinin was similar (all P>0.1). Alpha-tocopherol did not affect vasodilation to nitroprusside (P>0.1), acetylcholine (P>0.1) or bradykinin (P>0.1). CONCLUSIONS: There may be receptor-specific endothelial dysfunction in subjects with uncomplicated Type 2 DM. This is not improved by treatment with alpha-tocopherol.
