Exercise training confers a greater improvement in claudication and maximum walking distance than PTA, especially in patients with disease confined to the superficial femoral artery.

Symptomatic large bowel lipomata may be of considerable size and usually present in middle age with symptoms of obstruction or bleeding. Although they are rare, their recognition is important so that patients may be spared unnecessary colonic resection for a presumptive malignant diagnosis. Colonoscopic removal may often be feasible. Six cases are reported together with a review of the literature emphasizing the characteristic features.

In an ongoing study of patients on long-term etretinate (Tigason) therapy, 13 patients with a congenital or inherited disorder of keratinization and 10 patients with psoriasis were examined to investigate the incidence of, and the factors associated with, skeletal hyperostosis. Skeletal scintigraphy, plain radiographs, haematological and biochemical analyses were performed. Using all criteria, 7 of 13 patients with a congenital or inherited disorder of keratinization showed evidence of hyperostosis. No single investigation was able to detect all these cases; in particular, skeletal scintigraphy was positive in only nine of the 13 patients who showed hyperostosis. Eleven of the 13 patients with hyperostosis gave a history of musculoskeletal symptoms compared with three of the 10 patients without hyperostosis. There was no clear association with total dose or duration of treatment. Serum chemistry and haematological studies were normal. In two patients the 24-h urinary calcium excretion was significantly elevated, an abnormality which has not been described previously. Annual lateral thoracic spine radiographs with additional views of symptomatic areas are recommended for patients on long-term etretinate therapy.

Opportunistic screening for AAA in men undergoing clinically indicated abdominal ultrasonography is easy, productive, without discernible cost, and discloses a prevalence of AAA comparable with that of population screening programmes. Routine opportunistic measurement of aortic diameter during abdominal ultrasonography in the at risk group would allow 12-15% of men aged 65-74 to be screened for AAA within five years without the need for any additional resources.
