Palmar flexion creases and dermatoglyphics in leprosy patients.

Palmar configurations of 115 male and 48 female leprosy patients were compared with 536 males and 426 female normal individuals of the same population. The data was derived from Nekararu (weavers) castes of Karnataka State, India. Among flexion creases, the single radial base crease (SRBC) especially showed more association with leprosy in both male and female patients than their respective controls. Among dermatoglyphics, only C-line types are significantly different in male leprosy patients as compared to their controls. The female patients also showed more C-absent lines than the control group. The susceptibility to bacterial infection may be due to some biologic deficiency which warrants continued investigation on a broader and more intensive basis.

Palmar flexion creases and dermatoglyphics among diabetic patients.

Palmar dermatoglyphics and flexion creases of 108 male and 65 female patients diagnosed as having diabetes mellitus have been analysed. The control population consists of 536 males and 234 females from the same population. Palmar flexion creases were analysed according to the method suggested by Bali and Chaube ('71). The flexion creases of diabetic patients and the control population are significantly different. The differences between main line formulae in diabetes and controls are significant among males. The differences between C-line types of patients and controls are significant among both sexes. Axial triradii are significant among female patients and controls. The patterns in the interdigital areas IV and II are significantly lower among male and female patients respectively from their controls.
