A Study of Dermatoglyphic Patterns of Fingers in Patients with Myocardial Infarction

Background: The myocardial infarction (MI), the most common manifestation of coronary artery disease remains as a major cause of mortality in both developed and developing countries. The people without known major risk factors can be screened for MI with a simple and cost-effective tool which will be helpful in developing countries to reduce the mortality. Dermatoglyphic patterns in clinical conditions have been studied so far and their relationship is established in the literature. Dermatoglyphics has been considered as a diagnostic tool in many diseases with genetic bases. Hence this study is conducted to analyse the correlation between dermatoglyphic features and MI, so that dermatoglyphics may be used as screening tool for MI. Materials and Methods: We conducted a cross-sectional study of 150 MI patients diagnosed with ECG or coronary angiography who were admitted in the Institute of cardiology, Madras Medical College, Chennai after obtaining clearance from Institutional ethics committee. 150 healthy consented volunteers were included as controls. The finger prints from both groups were taken by ink method and type of fingerprint patterns and total finger ridge count (TFRC) and absolute finger ridge count (AFRC) were studied. The correlation of the findings between cases and controls were analysed with t-test and Chi-square test using SPSS 13.0. Results: The frequency of loop, arch and whorls is 54.9%, 8.3% and 36.8% respectively in MI as compared to 59.4%, 13.2% and 27.4% respectively in controls. The frequency of whorls is increased in thumb, middle finger and little finger of both hands of the MI patients when compared with controls with statistically significant difference (p<0.005). The mean value of TFRC and AFRC is increased in cases than controls and statistically significant difference was observed for AFRC. Conclusion: Thus, our study has indicated the specific fingerprint patterns in MI and we hope this knowledge can be used for screening the people without known risk factors for MI.

Characterisation of Finger Dermatoglyphics Traits and other Biometric Indices among Health Science Undergraduates of the Osun State University, Nigeria

Background: Finger dermatoglyphics has been useful in diagnosing genetically related diseases and detecting crimes. A cross-sectional study was carried out to establish the relationship between fingerprint traits and biometric indices Methods: Finger dermatoglyphics data were obtained using the ink method among the Health Sciences Students of Osun State University, Osogbo, Nigeria. Finger pattern intensity, finger pattern distribution, and finger ridge counts were measured and compared. These were done by counting and classifying ridge patterns and pattern configuration of arches, loops, and whorls and counting their ridge densities. The subject’s height, weight, and colour of the pupil were measured and recorded, respectively Results: The ulnar loops and arches were the most predominant finger patter ns in females, while males showed significantly spiral whorls. The sex differences between these patterns were not statistically significant (P>0.05). Subjects with brown pupils demonstrated higher ulnar loop and elliptical whorl, while those with black pupils possessed significantly well-distributed arches, and were insignificant in pattern width and intensity. Body Mass Index (BMI) polymorphism showed the lowest pattern size (Finger Ridge Counts) demonstrated by significantly reduced total finger ridge count among the subjects with BMI range of 24-26 and predominance of the concentric whorl, radial loop, and arches. However, higher pattern size was observed in subjects with a higher BMI value 27-29 BMI range with corresponding ulanr and spiral whorl respectively. Conclusion: This study demonstrated the prevalent biometrics measure of finger dermatoglyphics traits, in relations to the biometrics distribution of pupillary colour and body mass index among the Health Sciences Students of Osun State University, Osogbo Nigeria

A study of the dermatoglyphic pattern in diabetic subjects in Kalaburagi district

Dermatoglyphics is the scientific study of epidermal ridges and their configurations on the palmar region of hand and fingers and plantar region of foot and toes. Diabetes mellitus is a metabolic disorder characterized by hyperglycemia resulting from defect in insulin secretion, action or both. Dermatoglyphic patterns are genetically determined and can be used as supportive for diagnosis of various hereditary disorders including T2DM. This study was carried out to compare palmar dermatoglyphic pattern in T2DM and control group and compare with previous studies. A hospital based case control study was conducted 100 cases of T2DM are taken from Basaweshwar hospital Gulbarga, and another 100 persons are included as control group. The palms and fingers are smeared with ink to bring out the dermatoglyphiic patterns which were subsequently studied.There was increased number of whorls and decreased number of ulnar loops in both T2DM patients compared with normal individuals. Total finger ridge count and Absolute finger ridge count is increased in both T2DM patients and there is also increased atd angle. The knowledge of dermatoglyphics in patients with T2DM and essential hypertension can be utilized to find out genetic correlation. The existence of such relation might be important for the screening programme for prevention of T2DM.

Main characteristics of dermatoglypics associated with schizophrenia and its clinical subtypes

Dermatoglypic patterns are extensively investigated to apply in disease-related risk assessment due to an obvious association between morphological and genetic characteristics. In the current study, we aimed to determine whether the fingerprint and palmar patterns vary between case population with schizophrenia and general population. A cross sectional study was conducted in people diagnosed with schizophrenia (cases) and a control population between 2016 and 2019. In this study, 252 people were participated. Ink and paper method was used to evaluate the difference of fingerprints palm prints between patients with schizophrenia and participants in control group.93 participants were analyzed in schizophrenic group and 142 participants were investigated in the control group. The percentage of arches on the right ring finger was significantly different between the schizophrenic patient group and control group (p = 0.011). The whorl pattern type (U-W-U-W-W-W-W-U-W-U) was dominantly observed in both of the schizophrenic patient group and control group. A-B ridge count in schizophrenic patient group and control group produced a markedly significant difference (p<0.05). Interestingly, a strong significant difference was produced in comparing of A-B ridge count in catatonic schizophrenia group with residual schizophrenia group (p<0.005). In comparison, index of pattern intensity in control group was slightly higher than that in schizophrenic patient group. Taking together, these results showed that the dermatoglypic characteristics might be a valuable tool to describe the nature of schizophrenia and its clinical subtypes and further studies are needed in clinical application.

Dermatoglyphic Patterns of Children with Special Educational Needs

Background: The present study aimed at finding the finger and palmar dermatoglyphic patterns of students in special school and to discover whether significant dermatoglyphic features exist in students in special school. Materials and methods: Finger and palm prints were taken from 100 students from Garden City Special School which served as the study group and 100 students from “In Him is Life School” which served as the control group. Analysis of quantitative and qualitative traits of dermatoglyphs (Total Finger Ridge Count, atd angle, pattern type, symmetry of palmprint and type of PIC) were performed. Descriptive statistics were used to determine the differences among the groups. Results: Central pocket loop whorl (CPLW) which is an indicator in people with better academic performance was significantly lower (P<0.0001) in individuals in the special school (SS). The atd angle was significantly higher (P<0.0001) in both hands in SS than in CG. The current study revealed that the prevalence of symmetrical PIC was significantly lower (P=0.012) in the SS (39%) compared to CG (67%). Conclusion: Students in special school have unique dermatoglyphic pattern. There were significant differences in certain types of dermatoglyphic pattern observed in students in special school compared to students in normal school. Further study is required to have a baseline data which can serve as a diagnostic tool for early detection of people who need special attention.
