title: Clinical characteristics of Thai patients with psoriasis.
abstract: OBJECTIVE
  To reveal the clinical manifestations, aggravating factors, factor associated with severity, and treatment of psoriasis in Thai patients.
  
  
  METHODS
  The data of psoriasis patients who had been visited Dermatologic outpatient clinic, Siriraj Hospital between July 2002 and July 2008 were retrospectively reviewed.
  
  
  RESULTS
  One thousand eighty two patients were studied. The male to female ratio was 1.2:1 and the peak age of onset was in the 40 to 49 year-old age group. The most common aggravating factor was stress (50%), followed by trauma (39%) and weather condition (35%). The majority of patients had plaque type (72.8%). Male gender, smoking, alcohol intake, and nail abnormalities were related to severe psoriasis (PASI > 10).
  
  
  CONCLUSIONS
