By means of a questionnaire sent to all medical units in Malmö, including primary care, homes for the elderly, and industrial health clinics, 275 patients with leg and foot ulcers were identified. With a population of 232,908 in Malmö, this corresponds to a prevalence of 0.12%, which is lower than reported by others. Since the response rate was high (88% total, Primary Care: 100%), the prevalence of 0.12% is, however, believed to be real and might be explained by the urban area investigated, with easy access to care and proximity to one somatic hospital. 50% of the patients with leg and foot ulcers were treated in Primary Care, and 30% of the leg ulcer patients were treated at the Department of Dermatology. 88% of leg and foot ulcer patients were over 75 years of age. Median age was 79.5 years, with 80 for women and 76.5 for men. In Primary Care the median age was 82. There was a predominance of women in the study population with an overall sex ratio of 3:1. A higher proportion of patients living alone was found in Primary Care. The etiology of the ulcers was considered to be "unknown" or "other" or else no statement was given in 36% of the leg ulcer- and 22% of the foot ulcer patients. This might reflect an overall uncertainty about the underlying etiological cause. Medially and laterally located leg ulcers were reported equally often, but there was also a great proportion of wholly or partially circumferential ulcers. 76% of the foot ulcers were located on the toes.(ABSTRACT TRUNCATED AT 250 WORDS)

Questionnaires concerning nursing care of leg and foot ulcer patients in three major care-giving sectors of the national health service, namely the Department of Dermatology, general hospital wards/clinics, and primary care, have been analysed. The overall response rate was 88% (primary care: 100%). Forms regarding 193 patients with leg ulcers and 64 patients with foot ulcers were analysed. Substantial differences in nursing care were noted between the three sectors. In 55% of the leg ulcers and 45% of the foot ulcers fibrin slough was present in the ulcer. Black, necrotic tissue was present in 8% of the leg ulcers and 22% of the foot ulcers. Profuse ulcer-exudation was most commonly reported for leg ulcer patients treated at the Department of Dermatology, while the majority of foot ulcers had only a mild exudation. Frequency of dressing changes varied between 1.4 times/week for leg ulcers at the Department of Dermatology and 9.2 times/week (foot ulcers 11.6) at general hospital clinics. Local wound dressings were exclusively chosen by physicians at the Department of Dermatology, mainly by physicians at general hospital clinics, and equally often by physicians and nurses in primary care. Time since last evaluation of the ulcer by a physician varied. At the general hospital clinics, 89% of the patients with leg ulcers had been seen by a physician within the last 2-month period. At the Department of Dermatology, 89% and in primary care 61% of the patients were examined within this period. 11% of the patients in primary care had never consulted a physician for their ulcers.(ABSTRACT TRUNCATED AT 250 WORDS)

There is concern about the long-term carcinogenic effects of psoralen and ultraviolet A radiation (PUVA) therapy for treatment of skin disorders. A study of 4799 Swedish patients (2343 males, 2056 females; mean age at first treatment 45.3 years, range 6-93; mean follow-up 6.9 years males, 7.2 years females) who received PUVA between 1974 and 1985 showed a dose-dependent increase in the risk of squamous cell cancer of the skin. Male patients who had received more than 200 treatments had over 30 times the incidence of squamous cell cancer found in the general population. Significant increases (p less than 0.05) were also found in the incidences of respiratory cancer in males and females, pancreatic cancer in males, and kidney and colonic cancer in females. This study confirms previous reports of a dose-dependent increase in the incidence of squamous cell cancer in patients treated with PUVA.

A retrospective clinical survey of 96 patients with dermatitis herpetiformis (DH) was performed in two defined populations of 425,000 in southern Sweden. The incidence of DH was 1.05-1.13/100,000 inhabitants/year and the prevalence was approximately 20-25/100,000 inhabitants. In one-third of DH patients the age at onset was greater than 60 years. In women with DH a strong connection to thyroid dysfunction was observed, but also other conditions of probable autoimmune pathogenesis were found in both sexes. No connection to malignant disease was observed. DH seems to be less active the later in life it starts. Several patients with DH manage without dapsone or need dapsone just occasionally in connection with bouts. This is the case even without a gluten-free diet. Many mild cases of DH were observed without a gluten-free diet; therefore, this restricting regimen should be prescribed only in more active cases of DH.
