Since the mid-1970s, there have been substantial declines in liver cirrhosis deaths in many Western countries following a long period of increases. There is variability in the pattern of changes observed: in a sample of 29 countries between 1974 and 1982-83, seven countries showed a significant linear decline, three revealed a curvilinear pattern, increases were observed in six and the rest (13) showed no notable changes. Although reductions in per capita consumption of alcohol may be a contributing factor, these reductions do not seem to account for all of the decreases in cirrhosis deaths that have been observed. Among other factors that might contribute, changes or increases in treatment for alcohol abuse and AA membership have been most strongly linked to these declines; changes in patterns of consumption, dietary habits, prevention efforts and reduced exposure to predisposing factors may also be involved. In view of the importance of these declines for the understanding and prevention of alcohol problems, further research on this issue, perhaps involving international collaborative studies, is needed.  相似文献

Two cases of Wernicke's encephalopathy with severe hypothermia as a major presenting sign are reported. The outcome was favorable with thiamine treatment. The clinical features, frequency, prognostic value and clinico-pathological correlations of hypothermia in this condition are reviewed.  相似文献

The aim of the present case-control study was to assess the risk factors for Basal cell carcinoma (BCC) in the Montenegrin population. The study group was comprised of 100 consecutive patients with a diagnosis of BCC, while the control group consisted of patients who did not present skin cancer and who were individually matched to the cases by sex and age. The increased risk for BCC was associated with: the presence of nevi (odds ratio [OR] = 3.77; 95% confidence interval [CI] = 1.12–12.73), type of skin concerning to burn rather than to tan after repeated sun exposure in childhood or adolescence (OR = 3.14; 95% CI = 1.59–6.18), the skin reaction to burn after two or more hours of sunlight during childhood or adolescence (OR = 4.53; 95% CI = 2.37–8.63), the number of severe and painful sunburns during their lifetime(OR = 3.52; 95% CI = 1.68–7.38), outdoor work during the summer-time (OR = 2.73; 95% CI = 1.00–7.45), occupational exposure to chemicals (OR = 17.89; 95% CI = 2.82–113.52), history of eczema (OR = 4.17; 95% CI = 1.53–11.39), and history of previous BCC (OR = 3.86; 95% CI = 1.40–10.65). Our study confirms the role of environmental and constitutional factors in development of BCC.  相似文献
