ABSTRACT
To resolve the biomedical problems, palmar dermatoglyphics has been used as a method. For the screening of hypertension palmar prints can be used. We wanted to determine the correlation between dermatoglyphic angle and blood pressure.METHODSThis is a cross sectional study. Palmar prints of right and left hands were taken with the help of inkpad. Blood pressure was also measured and ATD angle of both the hands were measured with the help of goniometer in 200 females and 200 male subjects of North India. Percentages, Pearson’s chi-square test, Student independent t test, one-way ANOVA were used. A p value < 0.05 was considered statistically significant. Statistical analysis was conducted using SPSS version 20.RESULTSHypertension I and II were recorded for 7.0 % (6.0% of males and 6.0 % of females) and 2.3 % subjects (3.0% of males and 1.5 % females). Overall 28.3% of subjects had prehypertension. A statistically significant difference was observed in the value of left hand ATD angle for the comparison of hypertensive and non-hypertensive subjects.CONCLUSIONSDermatoglyphics can be used as a tool for the prediction of various diseases with a genetic link. Several studies nowadays show association of dermatoglyphic angle with hypertension.
ABSTRACT
Background: Dermatoglyphics is the study of quantitative and qualitative patterns of ridges in palms and soles.It is being investigated in diseases having genetic basis. The recent evidence from adoption studies has provideda basis for the genetic contributions in schizophrenia. The present conducted to study the finger and palmardermatoglyphic patterns in schizophrenics and to compare dermatoglyphic configurations of schizophrenicswith the normal population.Materials and Methods: The ink and pad method was followed to take finger and the palm prints. The palmarprints of 50 schizophrenic patients and 50 normal individuals of both the sexes were collected for the study.Results: There is statistically significant decrease in frequency of arches in schizophrenics when compared tocontrols, whereas frequency distribution of radial loops, ulnar loops and whorls are not significant. Increase inI4 interdigital pattern is statistically significant in schizophrenics when compared to controls. There is increasein the mean values of total finger ridge count in male, female and combined series of male and femaleschizophrenics and decrease in absolute finger ridge count in male and combined series of male and femaleschizophrenics, while there is decrease in female schizophrenics, when compared to controls. Atd angle isdecreased in both the hands of male schizophrenics and right hand of female schizophrenics as compared tocontrols, whereas it is equal in the left hand of schizophrenics and controls. There is increase in the mean ridgecount in III, IV and V digits in the right hand of male schizophrenics.Conclusion: There are significant differences in the schizophrenics in various dermatoglyphic features, whencompared to controls. Hence it is possible to identify the ‘at risk’ population with the help of dermatoglyphics.
ABSTRACT
Background: Breast cancer is very common among females these days, it’s occurrence has a strong genetic basiswhich has been already established. Palmar patterns also develop under genetic control during early developmentalmost at the same period when the mammary buds develop in intrauterine life. And they do not get alteredsignificantly after that, and thus remains almost constant during rest of the life. So these patterns may beassessed as a non-invasive anatomical marker to find the risk of developing breast cancer later in life.Methodology: In this study assessment of the palmar patterns of both hands of 109 female breast cancerpatients were taken and compared with the patterns of 109 age matched normal healthy females. The Patternswere obtained by Ink method in an A4 size white paper. Palmar ridge count (a-b ridge count), palmar angles ( atdangle and adt angle) of both the groups was measured and analysed.Results: On statistical analysis it was observed that mean a-b ridge count of right and left hands of cases weresignificantly lower when compared with the mean a-b ridge count of right and left hands of the normal healthyfemales respectively in Madhya Pradesh.Conclusion: The palmar ridge counts are significantly associated with breast cancer and in a highly populatedcountry like India with limited medical resources, it may be employed as an inexpensive and effective tool forscreening the high-risk population for breast cancer
ABSTRACT
Background: The susceptibility and severity of Rheumatoid arthritis are determined by both genetic and environmental factors. Dermatoglyphic patterns of individuals which are formed early in the fetal life are also determined by both genetic and environmental factors. Since both are genetically acquired and environmentally modified, it has been shown that there are particular dermatoglyphic patterns associated with Rheumatoid arthritis. If it is so, dermatoglyphics can serve as an additional tool in the early diagnosis and management of such a disabling disease like rheumatoid arthritis. Although there are some studies which mentioned dermatoglyphic pattern variation in the disease, the results are contradicting. Therefore, the present study was undertaken to find out a possible correlation of some quantitative and qualitative dermatoglyphic variables with Rheumatoid Arthritis. Aim of the study: To study the dermatoglyphic patterns in patients with Rheumatoid Arthritis and control population and to study the correlation between dermatoglyphic patterns and Rheumatoid Arthritis. Materials and methods: We studied 60 patients with Rheumatoid arthritis and 60 controls. All were subjected to detailed medical history and clinical examination. Both quantitative (finger ridge count and pattern intensity) and qualitative (fingerprint pattern) dermatoglyphic parameters were studied and the same were compared with age, sex and disease matched controls. Results: Out of the total 60 cases 12(20%) were male and 48(80%) were females. Of the total 60 controls, 12(20%) were males and 48(80%) were females. Analysis of the qualitative parameters revealed: Significant increase in the number of whorls in both the hands of female patients cases compared to the controls (p-value for right hand 0.001, p-value for left hand 0.004). The decrease in the number of radial loops in both the hands of male and female patients and the decrease was more in the left hand in males and right hand in females (p-value male left hand 0.002, female right hand Saritha K. Narayanan, Christopher C. Pais, Pradeep Kumar Shenoy. Use of palmar dermatoglyphics in rheumatoid arthritis - A case-control study. IAIM, 2017; 4(12): 70-76. Page 71 0.003). Decrease in the number of arches in the left hand of female patients compared to the controls (p-0.10). Analysis of the quantitative parameters showed: A statistically significant increase in the finger ridge count of individual hand and the total finger ridge count in both male and female patients compared to the controls (p-value males: right hand 0.003, left hand 0.004, right plus left hand 0.002; p-value females right hand.0000, left hand 0.000, right plus left hand 0.000). A statistically significant increase in the pattern intensity of fingers in female patients compared to the controls (p-value: right hand 0.006, left hand 0.001, right plus left hand 0.000). Conclusion: The findings of this work demonstrate the association between some of the qualitative and quantitative parameters of dermatoglyphics and Rheumatoid arthritis suggesting that dermatoglyphics can represent an anatomical, non-invasive, inexpensive tool for screening high-risk population and thus facilitate early detection and management.
ABSTRACT
Introduction: The ATD angle and finger ridge count, are palmar dermatoglyphics features of an individual. During the first & second trimester of pregnancy epidermal growth occur in stages and result in an increase epidermal thickness. Epidermal ridges begin to appear in embryos at 10th week and are permanently established by 17th weeks. The types of pattern develop in palm & soles are genetically determined. They are of considerable clinical interest because they affected by certain anomalies of early development including genetic disease. Objective: There are certain genetic (Chromosomal), Non chromosomal & metabolic disease shows particular palmer dermatoglyphics features so in this study we were trying to find out the difference in dermatoglyphics features in leprosy patient and control group. Materials and Methods: The sample consists of 100 cases of leprosy in age group of 18-60 year from Bhavnagar district. The finger print and palm print were taken by using ink & pad method and Compared with Control group of 18-60 years. The dermatoglyphics parameter like ATD angle, TFRC & AFRC were studied and evaluated for statistical significance. Results and Conclusion: There was statistically significant difference was observed in ATD angle as compared with control. There was no statistically significant difference observed in TFRC & AFRC as compared with control. The dermatoglyphics features can be useful diagnostically to differentiate the leprosy patient and control group.
ABSTRACT
Context: Palm prints formed once does not change throughout life and is not influenced by environment. Palmar Dermatoglyphics can indicate the development of potentially malignant and malignant lesions and help in identifying persons at high risk of developing Oral submucous fibrosis (OSMF) and Oral squamous cell carcinoma (OSSC). Aim: To analyze the qualitative [finger ridge pattern and presence or absence of hypothenar pattern] and quantitative [mean ATD angle and total AB ridge count] variations in Palmar Dermatoglyphics in patients suffering from OSMF and OSCC. Settings and Design: A prospective comparative study among 40 patients (Group I-10 samples of smokeless tobacco users with OSMF, Group II- 10 samples of smokeless tobacco users with OSCC, GroupIII- 10 samples of smokeless tobacco users without OSMF or OSCC and GroupIV- 10 samples without smokeless tobacco habit without OSMF and OSCC as controls) were selected. Materials and Methods: The palm prints were recorded using an HP inkjet scanner. The patients were asked to place the palm gently on the scanner with the fingers wide apart from each other. The images of the palm prints were edited and qualitative and quantitative analysis were done. Statistical Analysis Used: Statistical analysis such as Kruskal Wallis, Post Hoc and Analysis of Varience were done. Results: A highly significant difference among the finger ridge, hypothenar pattern and mean ATD angle (P<0.001) and total AB ridge count (P=0.005) in OSMF and OSCC patients were obtained. There is predominance of arches and loops, presence of hypothenar pattern, decrease in mean ATD angle and total AB ridge count in OSMF and Oral Cancer patients. Conclusion: Palmar Dermatoglyphics can predict the probable occurrence of OSMF and OSCC in smokelees tobacco users.
ABSTRACT
Nowadays study of dermatoglyphics has a great importance in judicial and criminal researches. Similarly its study is related to some genetic diseases has an immense applications. Diabetes Mellitus is the silent killer of mankind and public health problem. Therefore investigators are looking for new methods for its early diagnosis and treatment. Dermatoglyphics is a growing discipline and its ease and ready applicability render it as a useful tool to the clinician. Dermatoglyphics may be effectively employed as a screening procedure in future and may help in the early detection of cases of diabetes mellitus. Methods: The present study is undertaken with an aim to evaluate the dermatoglyphic features in diabetic patients. The study consists of 150 diabetic patients and 150 normal healthy individuals as controls. They were 75 males and 75 females in each group. Dermatoglyphic prints were taken by “Ink method” described by Cummins and Midlo and further subjected to statistical analysis to find the variations in the dermatoglyphic features among diabetic patients and control groups. Results: Mean value of a-b ridge count is neither increased nor decreased in diabetic patients (P = 0.852). Mean value of atd angle is slightly decreased in diabetic patients (P = 0.2332). The frequency of t and t' are increased (P = 0.8462, P = 0.6681) and the frequency of t" is decreased (P = 0.757) in diabetic patients but they are not statistically significant. Conclusion: From the present study, it appears that there do exists a variation in the dermatoglyphic patterns in diabetic patients with an advantage of being simple and economical ‘ink’ method. As the specific features of dermatoglyphic patterns are present in diabetic patients, it can be used for mass screening program to segregate the predicted diabetic patients.
ABSTRACT
American population consists of people of various race and ethnic group. Palm prints are different from each individual, ethnic group and race. The aim of this study is to investigate influencing anthropometric values to atd angles formed by triradii of palm prints in European American and develop a regression equation that can predict atd angle. This study was done on 208 European American (males: 102 individuals, females: 106 individuals). Data were collected by measuring atd angles using a protractor, distance from triradii a to d, length from triradius t to the distal wrist crease (DWC), palm breadth at metacarpals and palm length perpendicular using digital callipers. The data were analyzed by descriptive statistics, the frequency, independent sample t-test, paired t-test, Pearson correlation analysis, stepwise regression using SPSS win 18.0. This study showed that atd angles of males (38.6degrees) are significantly smaller than those of females (40.4degrees). Influencing anthropometric values to atd angles in males were distance from triradii a to d, the ratio of the length from triradius t to the DWC to palm length, palm length. Influencing anthropometric values to atd angles in females were the ratio of the length from triradius t to the DWC to palm length, the ratio of the distance from triradii a to d to palm breadth, and the ratio of palm breadth to palm length. In addition to, the regression equation predicted atd angle of males was 26.150+(0.741xdistance from triradii a to d)+(52.856xthe ratio of the length from triradius t to the DWC to palm length)-(0.332xpalm length), on the other hand, that of females was -42.935+(51.657xthe ratio of the length from triradius t to the DWC to palm length)+(63.314xthe ratio of the distance from triradii a to d to palm breadth)+(42.764xthe ratio of palm breadth to palm length). The results of this study suggest that there were differences in influencing anthropometric values to atd angles between males and females in European American. Especially, the ratio of the length from triradius t to DWC to palm length was a very significantly influencing anthropometric value to atd angles to all of males and females.

The palm prints are unique in each individual and permanent for a lifetime. The atd angle of palm is formed by triradii of palm prints. The aim of this study is to identify the reasons why males have smaller atd angles, even with larger palms than females have. This study was done on 379 individuals (males : 174 individuals, females : 205 individuals). Data were collected by measuring atd angles using a protractor, distance from triradii a to d, length from triradii t to the distal palmar crease (DPC), palm breadth at metacarpals and palm length perpendicular using digital callipers. The data were analyzed through the frequency, independent sample t-test, paired t-test, Pearson correlation analysis using SPSS win 14.0. This study showed that atd angles of 39.2 degrees in males are significantly smaller than those of females (40.5 degrees). Males' were wider than females' in palm breadth, palm length and distance from triradii a to d, however, there was no sexual difference in the length from triradii t to the DPC. In addition, the ratio of palm breadth to palm length was higher in males than in females, however, the ratio of the length from triradii t to the DPC to palm length, and the ratio of the distance from triradii a to d to palm breadth of males were lower than those of females. Especially, atd angles in males and females were more correlative with the ratio of the length from triradii t to the DPC to palm length. The results of this study suggest that the differences in the atd angles between males and females arise from the ratio of length from triradii t to the DPC to palm length and the ratio of distance from triradii a to d to palm breadth. In both of the cases, males exhibited lower ratios than females. Especially, the ratio of the length from triradii t to DPC to palm length affected more to the atd angle than any other ratios.
