Abstract

Alopecia areata subjects are characterized by asymptomatic, circular or oval smooth patches of complete loss of hair on scalp, the beard or elsewhere. In the present study alopecia areata subjects were examined in terms of dermatoglyphic characteristics and compared with that of controls. Frequency of loops was decreased in alopecia areata but in case of whorls and arches (not in male subjects) increased numbers are recorded than their counterpart. On palm, a-b ridge count (a-b RC) was found to be increased in both sexes of alopecia areata(statistically significant increase in alopecia areata Female) while atd angles were reduced in females. In male subjects of alopecia areata, true palmar pattern (TPP) was increased in both hypothenar and left interdigital-2 (ID2) areas while in females, TPP were increased in both inter digital area-2 and 3 and left ID4 areas. TPP were reduced in left thenar (Lt. Th.),Lt. ID1, ID3, ID4, Rt. ID2, ID3 and ID4 areas of alopecia areata males and both right and left thenar and hypothenar and right ID4 areas of females. This study reveals deviation in the form of reduction of number of loops and increase in number of whorls and arches in alopecia subjects. Deviation is also observed in a-b ridge count and atd angle. These can be considered as quite useful as a supportive investigation and to some extent knowing the prediction for alopecia areata.
