A multicentre epidemiological study on sunbed use and cutaneous melanoma in Europe

A large European case-control study investigated the association between sunbed use and cutaneous melanoma in an adult population aged between 18 and 49 years. Between 1999 and 2001 sun and sunbed exposure was recorded in 597 newly diagnosed melanoma cases and 622 controls in Belgium, France, The Netherlands, Sweden and the UK. Fifty three precent of cases and 57% of controls ever used sunbeds. The overall adjusted odds ratio (OR) associated with ever sunbed use was 0.90 (95% CI: 0.71-1.14). There was a South-to-North gradient with high prevalence of sunbed exposure in Northern Europe and lower prevalence in the South (prevalence of use in France 20%, OR: 1.19 (0.68-2.07) compared to Sweden, prevalence 83%, relative risk 0.62 (0.26-1.46)). Dose and lag-time between first exposure to sunbeds and time of study were not associated with melanoma risk, neither were sunbathing and sunburns (adjusted OR for mean number of weeks spent in sunny climates >14 years: 1.12 (0.88-1.43); adjusted OR for any sunburn >14 years: 1.16 (0.9-1.45)). Host factors such as numbers of naevi and skin type were the strongest risk indicators for melanoma. Public health campaigns have improved knowledge regarding risk of UV-radiation for skin cancers and this may have led to recall and selection biases in both cases and controls in this study. Sunbed exposure has become increasingly prevalent over the last 20 years, especially in Northern Europe but the full impact of this exposure on skin cancers may not become apparent for many years

Costs induced by hip fractures: a prospective controlled study in Belgium. Belgian Hip Fracture Study Group.

The economic burden of hip fractures is thought to be important, but the excess medical costs they induce remain largely unknown. We assessed the direct medical costs induced by hip fractures during and after hospitalization. Hospital costs of 170 consecutive Belgian women with hip fracture were gathered. During the year following discharge, all medical costs were collected for the 159 hip fracture women who survived the acute hospitalization stay. A similar collection of data was performed on a comparison group of 159 age-and residence-matched women without a history of hip fracture. The mean cost of the acute hospital stay was 8,667 Belgian francs and the mean 1-year hip-fracture-related extra costs after hospitalization was 6,636 Belgian francs. During the year following the acute hospital stay, 19% of the hip fracture women and 4% of the comparison women were newly admitted to nursing homes (p<0.001). Although health care costs increased with age, hip-fracture-related extra costs after hospitalization seemed similar in those below or above 81 years old. These extra costs amounted to 7,710 Belgian francs in women not living in nursing homes at the time of fracture, and to 3,479 Belgian francs in women who lived in nursing homes. Health or mental status before hip fracture seemed not to affect extra costs. Taking into account the higher mortality of women with hip fracture, the extra costs during the acute hospital stay and during the 1-year follow-up amounted to a mean 15,151 Belgian francs. In conclusion, both acute hospital stays and subsequent medical care contribute significantly to medical costs induced by hip fractures
