Is ultraviolet radiation avoidance affecting bone health in melanoma patients?

BACKGROUND: Ultraviolet (UV) radiation has numerous beneficial effects on human health, including stimulating vitamin D and serotonin production and immuno-regulatory activities. Conversely, UV radiation is also classified as a group one carcinogen by the International Agency for Research on Cancer. PURPOSE: To investigated the effects of UV radiation avoidance in melanoma patients in terms of vitamin D levels but also of bone mineral density and trabecular bone microarchitecture. METHODS: We conducted an observational study investigating the effects of UV radiation avoidance in 31 melanoma patients in terms of vitamin D levels but also of bone mineral density and trabecular bone microarchitecture by using dual-energy X-ray absorptiometry scan. Data were compared with two control groups of healthy subjects, who were chronically exposed or not exposed to UV radiation during their lifetime. RESULTS: Melanoma patients had on average slightly lower levels of vitamin D, without reaching statistical significance (P = .135). No significant difference was found across the three groups on T-scores of femoral neck (P = .544), of total hip (P = .617) and of lumbar spine P = .155). No significant difference was found on and trabecular bone score across exposure groups (P = .895). CONCLUSION: UV radiation avoidance does not seem to significantly impact vitamin D levels nor bone health in melanoma patients. Thus, UV protective behavior is advisable for all melanoma patients.

Healthy Hands: a pilot study for the prevention of chronic hand eczema in healthcare workers of an Italian University Hospital.

BACKGROUND: Healthcare workers are at risk for occupational chronic hand eczema (CHE) because of frequent handwashing and prolonged use of occlusive gloves. Prevention programs based on skin care education have been shown to be beneficial. We developed and assessed the efficacy of a skin care educational intervention for healthcare workers of our hospital. METHODS: The intervention consisted of two sessions, one week apart, each divided in a theoretical and a practical part, focusing on the skin barrier, types of eczema, risk factors for CHE, hand hygiene measures respectful of the skin, proper use of protective gloves and emollient creams. Its efficacy was assessed by a questionnaire, administered before and after the intervention, investigating the participants' knowledge of risk factors for CHE and risk behaviors. RESULTS: Twenty-three subjects, mostly (65.2%) nurses, took part in the intervention; 60.9% had a self-reported atopic background and 65.2% participants reported a history of CHE. The intervention improved significantly the participants' knowledge on CHE risk factors, i.e. frequent handwashing (P=0.023), surgical scrubbing (P=0.016) and prolonged glove wearing (P=0.022). The frequency of hand washing was significantly reduced (P=0.022). The participants gave a positive unanimous feedback. CONCLUSIONS: Our intervention was effective, by significantly improving the participants' knowledge and by inducing significant behavioral changes. Improving the formulation of alcoholic hand rubs may be a key factor to encourage their use. Coexisting nonoccupational risk behaviors are just as important in the prevention of CHE.
