Tamoxifen, a nonsteroidal antioestrogen, has been used as an adjuvant therapy in patients with oestrogen-receptor positive breast cancer for more than 10 years. Few cutaneous adverse side-effects of the skin are found with this therapy. In this study we present 20 cases of adverse skin effects in relation to tamoxifen during 1979-1997 reported to the Swedish Adverse Drug Reaction Register and 1160 skin side-effects reported to he World Health Organisation's International Collaborative Programme on Drug Monitoring. One new case report of radiation recall in conjunction to tamoxifen, with no sign of reactivation despite 18 months treatment with the tamoxifen analogue toremifene is also discussed in detail. This case illustrates that toremifene can be used as a second-line therapy in patients who have received radiation recall, on tamoxifen.

Patients with PsoA have an increased prevalence of raised serum IgA AGA and of coeliac disease. Patients with raised IgA AGA seem to have more pronounced inflammation than those with a low IgA AGA concentration.

With an aging population venous ulceration is likely to become an increasing problem. Despite improvements in care and the widespread introduction of compression bandaging, the mainstay of current management, a significant proportion of venous leg ulcers remain hard to heal. Therefore, a single-blinded, randomized multicenter study was performed to compare wound size reduction using amelogenin proteins (Xelma) formulated into a solution which forms a temporary extracellular matrix on contact with the wound bed. Propylene glycol alginate 7% served as a control. Patients were randomized to receive either amelogenin protein or control treatment. The investigational products were applied weekly under soft silicone secondary dressings for up to a maximum of 12 weeks. Compression therapy was maintained throughout the investigation. Wound size reduction was measured by tracing and all wounds were photographed. In total 123 patients were recruited, 62 patients in the amelogenin group, and 61 in the control group, respectively. Subgroup analyses were performed for ulcers with a size>10 cm2 at baseline and for ulcers of duration of >12 months. The wound size reduction was greatest in the group treated with amelogenin (33.8 vs. 25.6%, n=117), this difference being greatest for larger ulcers (25 vs. 7.9% for ulcers>10 cm(2), n=61) and those of long duration (29.3 vs. 10.9% for ulcers>12-month duration, n=61). We conclude that this product may be clinically useful in the treatment of these venous leg ulcers.

In Sweden, a cosmetic control system was introduced in 1989 at the Medical Products Agency (MPA). It consists of a register of importers, manufacturers and their products, and a voluntary adverse reaction reporting system identical to that concerning drugs. Between 1989 and 1994, MPA evaluated 191 reports concerning adverse effects of 253 cosmetics and toiletries. 90% of the reports concerned women and the top-ranking product category was moisturizers, followed by hair care products and nail products. The majority of the adverse effects reported involved only the skin, and 90% were eczematous reactions. 70% of the eczemas were classified as contact allergic, as patch tests were positive to the product as is, and in 1/2 of these products, 1 or more relevant allergens could be identified when tests were made with individual cosmetic ingredients. The most common offending ingredients were fragrances, toluenesulfonamide-formaldehyde resin and preservatives. The number of reports is small in relation to the expected number of cosmetic adverse effects, which can be explained by under-reporting. Efforts are being made to persuade Swedish physicians to report more often.
