title: The evaluation of microbiology and prognosis of fournier's gangrene in past five years.
abstract: OBJECTIVE
  Fournier's gangrene (FG) is an devastating disease that affects the perineum and genitourinary region, and is commonly a result of poly-microbial infection. This study is aimed to determine the correlation between micrology and prognosis of FG in the past five years.
  
  
  METHODS
  This study was a retrospective cohort study that was designed to study the trends in micrology and prognosis of FG. From the PubMed database, articles published in the recent 5 years (from Jan1(st), 2009 to Dec 31(st), 2013) were reviewed. A total of 19 articles (each with n > 30 and with thorough data descriptions in the topic of Fournier's gangrene), were enrolled in this study. The consolidated data was further analyzed by commercial statistical software (SPSS for Windows).
  
  
  RESULTS
  The twenty-two studies have covered FG cases from year 1981 to 2011, with a mean duration of 9.2 years. The total number of cases is 4,365. Majority of the cases are male (84.1%). The mean age and mortality rate is 51.8 ± 5 years old and 11.1 ± 8.9%, respectivly. The most commonly found pathogen is poly-microbial organism (54%), followed by Escherichia coli (46.6%) and Streptococcus (36.8%). The major risk factors are diabetes (43.7%), Body mass index of > 30 (40.7%), and hypertension (38.1%). Mortality rate in older patient group (age > 51.8 years old) is significantly higher than those of the younger group (22% vs. 5.5%, p = 0.0001).
  
  
  CONCLUSIONS
  Older patients with genital or perineal pain should be examined for crepitus dermis. When a patient is diagnosed with FG, swift consultation with surgeons and administration of broad-spectrum antibiotics are required in order to save the patient's live.
