Dermatoglyphic analyses in children with cerebral palsy.

This study was intended to elucidate the diagnostic values of dermatoglyphic features on the 45 cerebral palsy (CP) patients (28 boys and 17 girls). There were 50 healthy children in the control group. Dermatoglyphic samples were obtained from the both groups by using the paper and ink method and than analysed. The types of dermal patterns of fingertips, the counts of total ridges, the counts of a-b ridges, the values of atd angles, presence or absence of dermal patterns in the hypothenar, thenar/I, II, III, IV interdigital areas, presence of absence of the palmar flexion lines, were compared between the children with CP and control group. It was found that arch, radial loop, whorl prints have increased and ulnar print has decreased in boys investigated which was significant statistically (p < 0.001). No difference was found between investigation and control groups of girls (p > 0.05). The total ridge counts in boys and girls of the investigation group were found significantly decreasing according to the control group (p < 0.001). There was an important decrease in the counts of a-b ridges of investigation group as compared to controls. It was significant in boys (p < 0.01) but not in girls (p > 0.05). The values of atd angles of the investigation group have increased in the control group (p < 0.001 in girls and p < 0.01 in boys). The dermal prints in the hypothenar, thenar/I, II, III and IV interdigital areas showed important differences in the investigation group when compared with the control group (p < 0.01). No clear distinction occurred between the two groups from the viewpoint of palmar flexion lines (p > 0.05). In conclusion, remarkable differences in comparison to controls were found in the dermatoglyphic features of CP cases. In our opinion, by undertaking more studies on the subject and examining a higher number of cases it will be possible to obtain useful data in CP cases indicative of etiologically.
