title: Dermatoglyphic patterns in cystic fibrosis children.
abstract: OBJECTIVE
  It is believed that fingerprints and palm patterns may represent genetically determined congenital abnormalities in Cystic Fibrosis (CF). The main idea of this paper was to determine differences of fingerprints and palm patterns in CF and normal children.
  
  
  METHODS
  Forty-six CF children (27 males, 19 females) and 341 (113 males, 228 females) healthy individuals were recruited for this study. Fingerprint patterns, Total ridge count (TRC) of each finger, a-b ridge count, and atd angles of all participants were recorded. Asymmetry of the right and left hand for each value was determined and dissimilarity in fingerprint patterns between homologous fingers was compared using Chi-square analysis, Mann-Whitney U test and Fisher's exact test.
  
  
  RESULTS
  There were significant differences in the mean TRC of the right digit IV (P=0.009), left digit III (P=0.02), left digit IV (P=0.03), and left digit V (P=0.03). Furthermore, we found significant differences in right atd angel (P=0.001), left atd angel (P=0.002), right a-b ridge (P=0.007) and left a-b ridge (P=0.001). In contrast, we found no significant differences in atd angle asymmetry, a-b ridge count asymmetry and pattern dissimilarity score between both groups (P>0.05).
  
  
  CONCLUSIONS
  Dermatoglyphic characteristics could be used as a supplementary diagnostic method in CF children.
