Venous insufficiency is a widespread condition, the prevalence of venous ulceration being 0.5-1.0 per cent in Western populations. A principal abnormality causing venous insufficiency is deep venous reflux, usually resulting from post-thrombotic valve destruction. ⋯ Although treatment for superficial and communicating vein incompetence is available, correction of deep vein reflux has been neglected until recently. Deep vein valve physiology, the selection of patients for deep vein valve surgery and methods of valve repair and replacement are reviewed.

Among 18,403 male civil servants examined at age 40-64 years there were 99 deaths attributed to aortic aneurysm during 18 years of follow-up. Each case was matched by age to ten controls who survived longer than the case. ⋯ The independent effects of height, adiposity, plasma cholesterol, glucose intolerance, reported angina and intermittent claudication were not significant. Hypertension and smoking, particularly of hand-rolled cigarettes, are confirmed as major and potentially remediable risk factors for fatal aortic aneurysm.

Ultrasonography with graded compression was performed in 525 patients with clinical signs of acute appendicitis. Of 207 patients with surgically proven appendicitis the inflamed appendix (diameter greater than or equal to 6 mm) had been visualized sonographically in 177 (86 per cent). The score for non-perforated appendicitis (91 per cent) was higher than for perforated appendicitis (55 per cent). ⋯ In four patients a false positive sonographic diagnosis of appendicitis was made and in two patients with appendicitis an alternative condition was incorrectly diagnosed. During the last 3 years of the study the negative appendicectomy rate was 7 per cent and delay beyond 6 h after admission occurred in only 2 per cent of patients with surgically proven appendicitis. When used to complement the clinical diagnosis ultrasonography improves the diagnostic accuracy and patient management in those suspected of having acute appendicitis.

Primary hyperhidrosis, although lacking a precise definition and of unknown aetiology, disrupts professional and social life and may lead to emotional problems. A variety of treatment methods are used to control or reduce the profuse sweating which involves mainly the palms, soles and axillae. The simplest method, the application of topical agents, is usually attempted first for axillary and plantar sweating. ⋯ For upper thoracic sympathectomy a variety of surgical approaches are used with satisfactory relief of hyperhidrosis. Complications related to the surgical approach, such as Horner's syndrome, brachial plexus injuries, pneumothorax and painful scars may occur, while following sympathectomy compensatory hyperhidrosis is usual and hyperhidrosis may recur. Plantar hyperhidrosis which may be exacerbated or ameliorated by upper thoracic sympathectomy and which fails to respond to non-operative intervention is relieved by lumbar sympathectomy.
