Aromas and fragrances are present in many cosmetics, some topical drugs, food and various hygiene, household and industrial products. They can be responsible for contact dermatitis. Multiple sensitizations can even involve in various combinations some fragrance compounds, a given degradation product or a contaminant. The diagnosis relies on clinical examination and oriented anamnesis. A histological examination is sometimes necessary. Specific path testing brings insight on the culprit chemical compounds.

The Mosan Study Group of Pigmented Neoplasms was founded about 15 years ago. It has collected more than 20.000 cutaneous malignancies including melanoms and basal and squamous cell carcinomas. The incidence of these cancers in on the rise in Wallonia. In particular, malignant melanoms represent a spectrum of emerging cancers characterized by a proteiform biological outcome. They mostly affect young women. The major risk factor appears to be iterative and unwise ultraviolet exposures. The prevention of malenomas is basically founded on such a dogma and accordingly relies on sunscreens. However, controversies about their beneficial effects are rife and fueled by axiomas and contradictory sophisms. At the exception of surgery, the therapeutic options for the diverse types of melanomas do not yet fulfill the scope of evidence-based medicine. [less ▲]

Background: In patients undergoing long-term hemodialysis, a peculiar hyperpigmentation develops, the intensity of which may or may not be related to the duration of treatment and use of erythropoietin. Objective: Our purpose was to conduct a comparative cross-sectional study of white patients with distinct diseases that modify their skin color. Methods: A reflected-light colorimeter was used to compare the color of the forehead and forearms of 61 white patients receiving hemodialysis with that of matched controls and of patients with anemia or icterus. Results: Significant differences were found in both reflectance and chromaticity between these groups of patients. Duration of hemodialysis and use of erythropoietin did not significantly influence the colorimetric measurements. Conclusion: The use of a color-reflectance meter allows precise evaluation of subtle changes in skin color and may be used to monitor several diseases. [less ▲]
