    Notes: Chronic wounds are a challenge for modern health care. A basic principle of treatment is the removal of sloughy, necrotic, devitalized tissue to prevent wound infection and delayed healing. Biosurgery (syn. maggot or larval therapy) is a promising adjunct to the whole spectrum of topical treatment methods, in particular for debridement. The term ‘biosurgery’ describes the use of living maggots on wounds to remove devitalized tissue, decrease the risk of infection and improve wound healing. The present paper gives a brief review of history, entomology, biochemistry and medical indications of biosurgery and the practical handling of maggots. We also provide some clinical data from the literature and our own experience in a wound care unit. Biosurgery is an effective and safe treatment option for debridement and disinfection.

    Notes: Abstract S100 protein is well established as a diagnostic tool in malignant melanoma immunohistology. In this study we measured S100β in serum with a recently developed luminometric immunoassay with a detection limit of 0.02 μg/l. By measuring S-100β in a group of apparently healthy individuals a mean value of 0.031 ± 0.026 μg/l was found. In the reference group, serum S100β was below 0.12 μg/l in all cases. To assess the sensitivity of the assay we investigated serum S-100β levels in 371 serum samples of 315 patients with histological proven malignant melanoma at different disease stages. Staging was performed according to the German Society of Dermatology classification. Significant differences were observed between the control group and stages IIb (P = 0.01) and IV (P = 0.001). In tumour-bearing patients of stages IIIb and IV, the difference was highly significant (P 〈 0.0001). S100β 〉 0.20 μg/l helps to distinguish between tumour-free and tumour-bearing patients with a specificity of 97.0% and a sensitivity of 64.6%. Our results demonstrate the serum S100β is of limited value as a melanoma marker. However, it has clinical significance for identifying tumour-positive patients in advanced malignant melanoma stages III and IV.
