title: Study on dermatoses and their prevalence in groups of confirmed alcoholic individuals in comparison to a non-alcoholic group of individuals.
abstract: BACKGROUND
  The direct relationship between alcoholism and dermatoses has been evaluated in recent researches. However, there are few objective surveys that demonstrate and prove a direct relationship between alcohol and a specific dermatosis.
  
  
  OBJECTIVE
  to verify the prevalence of dermatoses in alcoholics, analize the dermatological changes found in these patients and their evolution during alcoholic abstinence. Also, to compare the results obtained with a non-alcoholic control group and with the data found in medical literature.
  
  
  METHODS
  the dermatologic conditions of 278 alcoholic patients (250 men, 28 women) were studied over a period of 4 years, and compared to those of a control group of 271 non-alcoholic individuals (249 men, 22 women), members of the Military Police Force. The individuals in both groups were between 20 and 60 years old.
  
  
  RESULTS
  Pellagra, nummular eczema, purpura pigmentosa chronica (also known as pigmented purpuric dermatosis) and psoriasis were more frequent in the group of alcoholics and, apparently, occurred in parallel with alcoholism that seems to play a role in the evolution of these dermatoses. The dermatopathies were more frequent before the age of forty, regardless of factors such as profession, race or gender.
  
  
  CONCLUSIONS
  the association of dermatoses and alcoholism was extremely significant according to the statistical data. Alcoholism can be considered a risk factor for pellagra, psoriasis, nummular eczema and purpura pigmentosa chronica dermatoses, which can, as well, be considered alcoholism indicators.
