Dermatoglyphics in pulmonary tuberculosis

  1. 1. Palmar Dermatoglyphics In Pulmonary TuberculosisSangita S Babu, B.P. Powar, O.N. KhareR.D. Gardi Medical College Ujjain (MP) Abstract: Studies were conducted in 100 patients of Pulmonary Tuberculosis and various dermatoglyphics param-eters such as ‘atd angle, finger print pattern, absolute finger ridge count and total finger ridge count were calculated.These parameters of study group were compared to those of controls. It was observed that the whorl pattern (56.6%) werepre-dominant with a decrease in loop pattern (32.1%) when compared those of controls and the difference was highlysignificant (P< 0.01). The difference in the mean total finger ridge count of the controls and study group was found to behighly significant (P< 0.02) ; while the difference in mean absolute finger ridge count of the controls and of the patients ofpulmonary tuberculosis was found to be statistically significant (P<0.05). The ‘atd angle had narrowed in the study groupwhen compared to controls and the difference was highly significant (P<0.02). Key Words : Palmar prints, tuberculosis, dermatoglyphics, axial triradius.Introduction (56.6%) were pre-dominant in the study group when Dermatoglyphics is the study of surface markings compared to controls (23.8% ) which was highlyof the skins, especially of the palmar and plantar significant (P<0.02) while the study group showed aregions. The study of dermatoglyphics was pioneered decrease in loop pattern (32.1%) while in controls it islong back by Galton (1892) and it is a simple yet (73.3%) and the difference is highly significantcomplicated tool in the study of genetic disorders. The (P<0.01). The arches were very much reduced in thestudy of palmar pattern is done especially it provides study group (3.3%) while in the normal population wasa better in sight in to the study of the disease under found to be (11.3%). But these differences wereconsideration. statistically in significant (P>0.05) Tuberculosis, an infectious disease caused by On considering the occurrence of the patterns inmycobacterium tuberculi is a world wide public health both the palms, the ring finger is having maximumproblem. The purpose of studying dermatoglyphics is percentage of whorls (90%). Thus it can be assumedto derive a diagnostic criteria from the dermatoglyphic that the most common pattern in pulmonarypoint of view. tuberculosis patients is whorls in their ring finger. (refer Table 1)Materials And Methods TFRC: Total finger ridge counts is the number of In the present study 100 patients of pulmonary ridges from the triradius to the core pattern, and istuberculosis (sputum +ve) were collected from the counted for all the digits of both hands.department of TB & Chest.

Finger counting on the tip of all digits of both hands from allprints and palm prints were taken with the help of the triradi present. Because a whorl is having 2 triradiprinters ink on white paper by ‘ink & paper’ method. there will be 2 counts in whorls. On considering ridgeAfter that these prints were studied for the pattern counts the ridge count of a whorl is between 11 to 15.types, total finger ridge count (TFRC), absolute finger The AFRC was calculated in both the normals andridge count (AFRC) and ‘atd’ angle with the help of a study group and the value in the normals is 122 + 18.9hand lens.
