Abstract

Different variants in the digital flexion creases are found in a number of syndromes, but rarely found in phenotypically normal individuals. This study was designed to observe the changes of dermatoglyphics in single interdigital flexion crease of the fifth finger present bilaterally in Bangladeshi Down syndrome people and to compare it with the normal subjects. This cross sectional observational analytical study was conducted in the department of anatomy, Chittagong medical college (CMC), Chattogram from January 2018 to January 2019. A total of 200 participants were included where 100 Down syndrome people were collected from different organization of Down syndrome society in Bangladesh. 100 MBBS and dental students of Chittagong medical college both male and female were selected as control. Dermatoglyphics print was taken by the ink and paper method described by Cummins and Midlo. Detailed dermatoglyphic analysis was done by using magnifying glass, calculator, and scale. After collection data was analyzed for statistical significance by chi-square test wherever applicable, by using a computer-based program SPSS 23 and MS Excel. P value was considered significant if it is < 0.05 at 95% level of confidence. The presence of a single flexion crease on the fifth digit replacing the normal two interpharyngeal creases were observed in right hand 12% and in the left hand 15% of the Down syndrome people and none of the control. It is revealed that there are significant differences on single bilateral interdigital flexion crease of the fifth finger between Down syndrome people and control.
