Comparative study of dermatoglyphic patterns in identical twins

Abstract Background and aims: Dermatoglyphics has been studied extensively in chromosomal disorders and also in various diseases. Identical twins cannot be distinguished based on DNA. It is claimed that identical twins can be distinguished based on their finger prints, retina, and thermogram and iris patterns. It will be really interesting to know whether the identical twins have same dermatoglyphic patterns or not. Materials and Methods: 24 pairs of identical twins were examined for quantitative and qualitative similarities of finger print patterns; patterns on the palm, ‘atd’angle, ‘a-b’ridge count and palmar creases. Finger prints were evaluated for loop, arch, whorl and the data was recorded. Paired sample correlation test was applied to analyse ‘a-b’ridge count and ‘atd’ angle. Results: We have found that on comparison of finger tip patterns there are differences of about 33.33%. ‘a-b’ridge count in cases studied showed mean range from 38.23 to 38.37 on right and left hands respectively. This indicates there is close similarity in the ‘a-b’ridge count of identical twins, ‘atd’ angle showed close similarity in mean ranging from 46.23 to 46.10 on right and left hand respectively. Conclusion: Finger tip patterns is superior parameter to differentiate Identical twins compared to ‘a-b’ridge count and ‘atd’ angle.

The evaluation of cases using synthetic cannabinoid in Trabzon and the surrounding provinces

Although popularly considered as a modern utility, the study of fingerprints and skin ridge patterns is probably the oldest of all sciences. Fingerprints once formed remain permanent and never change throughout the life. The present study includes 150 cases of angiographically proven myocardial infarction patients and 150 cases of healthy normal individuals. The fingerprints of both hands were taken by plain and rolled method on white paper to determine the correlation between fingertip patterns and myocardial infarction. It is noted that there is significant decrease in loops in thumb in males with significant increase in whorls in little finger in males, and thumb and little finger in left hand in myocardial infarction patients. Also there is significant decrease in arches in little finger in males and thumb in females with significant increase in arches in little finger in females in myocardial infarction patients. Moreover, there is significant decrease in loops with corresponding increase in whorls in males, (M+F) combined series and left hand of myocardial infarction patients as compared to the controls. The mean value of finger ridge count in myocardial infarction patients is increased in both sexes but not significant. Thus, apart from its use in forensic science for identification and disputed paternity, fingerprint can also be use in predicting the myocardial infarction in healthy individual at an earlier age.

Dermatoglyphic patterns of goitrous children in endemic iodine deficiency area

Background Goiter mapping on elementary school students in1998 showed that the prevalence of endemic goiter was still highat Enrekang regency, South Sulawesi despite various programs tomanage this problem. This raised questions if there were any otherfactors that contribute to the occurrence of goiter e.g. genetic fac-tor, which can be assessed indirectly by dermatoglyphic pattern.Objective To determine the dermatoglyphic pattern in goitrouschildren and compare it to normal children.Methods A cross sectional study was done to investigate the cor-relation between goiter and dermatoglyphic patterns on 115 el-ementary school students at Anggeraja and Baraka subdistricts,Enrekang regency. Dermatoglyphic patterns of finger tips of bothhands and right hallux were scanned using Prolink scanner withMaximum Resolution of 19200x19200dpi and interpreted usingphoto/image editing computer program.Results Seventy two (62.6%) of 115 children were goitrous, sev-enty (97%) were of stage1, and 2 (3%) of stage 2. No significantdifference was found in dermatoglyphic patterns between normaland goitrous children. Tibial loop pattern of the right hallux tendedto be more frequent in goitrous children than that of normal chil-dren, but it was not statistically different (in level of significancy of0.05) compared to normal children (p=0.085).Conclusions This study indicates that the possibility of the role of ge-netic factor in the development of goiter in endemic area is unlikely

Association of Dermatoglyphic Peculiarities with Dental Caries in Preschool Children of Lucknow, India

ABSTRACTBackground: Dermatoglyphics refers to study of the intricate dermal ridge configurations on the skin covering the palmar and plantar surfaces of hand and feet. The basis of considering dermatoglyphic patterns as genetic marker for dental caries is that the epithelium of finger buds as well as enamel has ectodermal origin, and both develop at the same time of intrauterine life.Aim: To assess the relationship between fingerprint patterns and dental caries among preschool children of Lucknow city.Study design: This study was of cross-sectional design.Materials and methods: The study group comprised 512 preschool children 2-6 years of age. The prevalence of caries was recorded using "Dentition status and treatment needs" (WHO basic oral health assessment form, 1997). They were divided into three groups as follows: Group I (dmft score = 0-2), group II (dmft score = 3-4) and group III (dmft score ≥5). The handprints of each child were taken using a stamp pad. The fingertip patterns were analyzed according to the classical method and were classified according to the topological method. The frequency of occurrence of type of dermatoglyphic pattern on fingertip of each digit was noted.Statistics: Chi-square test was used to test the significant difference in proportions. Means were compared using Student’s t-test and analysis of variance (ANOVA) or F-test.Results: Subjects belonging to groups II and III showed maximum occurrence of whorl pattern on all digits. Group I subjects had maximum occurrence of arch pattern. All the variables had statistically significant value, with a degree of divergence of specific dermatoglyphic patterns among all three groups.Conclusion: The dental caries susceptibility of an individual increased with incidence of whorl pattern and it decreased with incidence of arch pattern.How to cite this article: Singh E, Saha S, Jagannath GV, Singh S, Saha S, Garg N.

The aim of this study was to find out the range of dermatoglyphic abnormalities io syndactyly patient because of close association between underlying tissue (derived from mesoderm) and overlying epidermis (derived from ectoderm) duriog embryogenesis of hand. Materials and methods : Present study was carried out io 20 patients with congenital syndactyly of fingers. The authors evaluated fingertip patterns, axial triradius, palmar pattern, flexion creases, a-b ridge count, digital triradii and pattern intensity. Results : Remarkable dermatoglyphic variations were observed io syndactylous hands, which were rare io normal hands. Conclusion : There are certain specific associations between anomalous hands and dermatoglyphic patterns indicating that underlying mesenchyme influences the development of epidermis derived from ectoderm and so the ridge pattern.

A comparative evaluation of dermatoglyphics in different classes of malocclusion.

AimTo study associations of dermatoglyphic features with malocclusion in Indian children.Materials and methodsA total of 237 children aged 12–16 years, who attended our outpatient clinic in a government medical college, were selected. Finger and palm prints were collected, and fingertip pattern frequencies, total ridge counts (TRCs), and atd angles (formed by the triradii below the first and last digits and that in the hypothenar region of the palm) were calculated. These parameters were analyzed with their Angle’s class of malocclusion using appropriate statistical tests. Dermatoglyphic parameters were examined and asymmetry analysis was conducted in subjects with different occlusion patterns.ResultsAlthough no fingerprint pattern was found to be specific for a particular class of occlusion, increased tendencies toward high frequencies of whorls in subjects with class II malocclusion and plain arches in those with class III malocclusion were observed. Significant differences in atd angle and TRC were observed among malocclusion types (p = 0.0001). Asymmetry scores did not differ significantly.ConclusionDermatoglyphic analysis can be used as an indicator of malocclusion at an early age, thereby aiding the development of treatments aiming to establish favorable occlusion. Inheritance and twin studies, as well as those conducted in different ethnic groups, are required to examine these relationships further.

Qualitative analysis of dermatoglyphics in oral submucous fibrosis

Aim: The study was conducted to analyze the significance of dermatoglyphics in predicting the development of oral submucous fibrosis (OSMF) among gutkha chewers. Objective: To evaluate the finger tip patterns in OSMF patients. Materials and Methods: The study was conducted on 75 subjects selected randomly from the OPD of Oral medicine and Radiology, out of which 25 subjects were gutkha chewers with OSMF, 25 were gutkha chewers without OSMF, and 25 were healthy subjects who were used as controls. The fingertip patterns were recorded using duplicating ink on A3 size paper and analyzed for their configurations using a magnifying lens. Results: Statistical analysis showed significant increase in the percentage of loops among gutkha chewers with OSMF and controls, and significant increase in the whorl patterns among the control group. The distribution of finger tip patterns of all the digits showed statistically significant increase in whorl pattern in right index (RI) and right ring (RR) finger. Conclusion: The present study showed a significant increase in the loop pattern among gutkha chewers with OSMF in comparison to controls. Thus, it can be concluded that people with more number of loop patterns are more prone to develop OSMF as compared to those with other patterns. Hence, dermatoglyphics can be used in this modern era to forecast the future of gutkha chewers, without much intervention.

Gender determination from fingerprints

INTRODUCTION: Fingerprints are one of the most mature biometric technologies and are considered legitimate proofs of evidence in courts of law for human identification all over the world. There is relatively less research has been done for its use in this field of gender identification. Hence, the present study was done to look the correlation between fingertip patterns with the gender of an individual. METHODS: Study was carried out over a period of one month among 200 medical students (100 male & 100 female) belonging to the age group 18-25 years of Kathmandu University School of Medical Sciences, Dhulikhel, Kavre. RESULTS: Each finger print is unique; loops are the most commonly occurring fingerprint pattern while arches are the least common. Males have a higher incidence of whorls and females have a higher incidence of loops. CONCLUSION: We can conclude that there is an association between distribution of fingerprint patterns and gender and thus prediction of gender of a person is possible based on his fingerprint pattern.

A Comparative Case Study of Fingerprint Patterns in Male Convicts of Sabarmati Jail (Ahmedabad) in Gujarati Population

There are numerous applications of fingerprints for human identification as they are unique and extensively used tool for identification of criminals during forensic investigations, in both civil and criminal cases. More elaborate studies are required with reference to ethnic and geographical variations in Gujarat which could be useful in creating a biometric database of fingerprints in which criminal history of convicts could also be included which will go a long way in supporting the criminal justice system and law enforcement agencies. Therefore the study was conducted on the convicts of Sabarmati jail to assess the patterns frequency in the fingertips of the criminals and their comparison with reference to normal Gujarati population (control). The study revealed that the convicts (male) had greater frequency of patterns than control (males) but statistically there was no association between the control and convict related to patterns in the respective digits. As seen from the p-value of the tests, we conclude that H1 is accepted i.e. there is association between right and left hand finger tip patterns in control males, convict males and their total also. Statistically it has also been found that there is no association between fingerprint patterns in both hands of convicts and control.

Dermatoglyphics and karyotype analysis in primary amenorrhoea.

Dermatoglyphics is the scientific study of the skin ridge patterns on the fingers, toes, palms of the hands and soles of feet. Dermatoglyphics is in use as a supportive diagnostic tool in genetic or chromosomal disorders as well as in clinical conditions with genetic etiologies. Primary amenorrhoea and Dermatoglyphics, both have the suspected multifactorial (genetic and environmental) aetiologies. In the present study the finger dermatoglyphic patterns were studied in primary amenorrhoea cases and age matched fertile control females and also attention was given to find out whether a specific dermatoglyphic trait exists in primary amenorrhoea cases and whether it was statistically significant. To study the role of dermatoglyphics in primary amenorrhoea, a study was conducted on 30 subjects with primary amenorrhoea (as cases) and compared it with equal number of age matched fertile females (as controls). We studied fingertip patterns in all the subjects enrolled. Simultaneously we have assessed the Karyotype of primary amenorrhoea cases. Two subjects in experimental group have shown abnormal Karyotypes. The most significant finding in present study was increased total finger ridge count (TFRC) in primary amenorrhoea cases which was statistically significant. We also found higher frequency of loops and arches in primary amenorrhoea with abnormal karyotypes. This type of study may be quite useful as a supportive investigation, in stating the predisposition of an individual to primary amenorrhoea and referral of an individual for karyotyping.

The Study of Dermatoglyphic Patterns and Distribution of the Minutiae in Inherited Essential Hypertension Disease

The aim of this study is to determine the effects of dermatoglyphic patterns in inherited Essential hypertension disease which could be useful for early diagnosis and preventive care. The sample studied for this research was obtained from 40 patients with inherited Essential hypertension disease and 20 normal subjects without any symptoms of Essential hypertension disease until 2 generations ago. Print of their palm and fingers was obtained in two groups by printing ink. Patterns of finger tips, ATD angles, A-B ridge and the different types of minutiae were located, identified and quantified visually inside of four sectors of fingerprints. The result of this study showed two patterns of finger tips; Whorl and arch in diseases are more than normal people. The most common tips in normal people is loop. In average the number of the A-B ridge in female illnesses and male normal are respectively more on average than female normal and male illnesses. The ATD angle is lower in patients than in normal. Results of the survey on minutiae showed that frequency of the ridge Ending (E) is between 32-52.52 with the highest frequency. Frequency of Bifurcation (B) is lower than the ridge ending which it is between 17.39-35% in left hand, but in right hand the second most patterns is convergence (C) which is between 14.13-38.66%. The third most patterns in left hand was observed in pattern convergences (C) with a percentage between 8.62-32.6, but in right hand the third most patterns is bifurcations (B), which is between 3.57-24.81%. Also in some sector of fingers significant difference was found.

Dermatoglyphic assessment in subjects with different dental arch forms: an appraisal.

Successful rehabilitation of edentulous individuals involves selection and arrangement of artificial teeth in accordance with the patient's original arch form. Various criteria exist for harmonious tooth arrangement but none is accepted universally. Finger and palm prints are unique to an individual and once formed in the sixth week of intra-uterine life, remain constant thereafter. Since dental arches are also formed during the same prenatal period, it is believed that the similar genetic factors may be involved in formation of dental arches and dermal patterns. This study was conducted to identify the association if any between type of dental arch forms and type of dermatoglyphic patterns. If specific dermal characteristics exist in individuals with specific dental arch forms, dermatoglyphic assessment of long standing edentulous subjects may help identify the patients preexisting dental arch form and thus aid in proper tooth arrangement. Ninety dentulous subjects were categorized into three groups on the basis of dental arch form (square, tapering or ovoid) and their finger and palm prints were recorded. The type of fingertip patterns, distribution of palmar patterns, Total Finger Ridge Count and angle atd were assessed. Subjects with square arches demonstrated a significantly high frequency of loops and a large atd angle with palmar patterns being most frequent in I3 region. Subjects with tapering arches showed a high frequency of whorls, a small atd angle and greatest distribution of palmar patterns in I4 region. In ovoid arched subjects, loops were the most common and palmar patterns were mostly observed in I4. Since distinctive dermal patterns were observed in subjects with different dental arch forms, it is believed that dermatoglyphics may be used as a reliable tool for identifying original arch form in edentulous patients.

BACKGROUND : 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. The myocardial infarction is almost always caused by coronary artery disease. Against the genetic background of dermatoglyphic patterns and coronary artery disease, the study was undertaken to determine the correlation between them. AIMS To do a comparative study of the dermatoglyphics (finger tip pattern) in patients with myocardial infarction and control group and to assess the usefulness of finger tip pattern in serving as a predictor for myocardial infarction. SETTING AND DESIGN: The study was done in 200 persons of age between 40 to 75 years . Out of them,100 were confirmed cases of CAD and 100 were normal healthy controls. METHODS AND MATERIAL: The finger and palmar prints of both hands were taken on white paper by Ink method and kores duplicating ink was used for taking the prints . STATISTICAL ANALYSIS USED: In statistical analysis SPSS software was used and Z test was used. The p value less than .001 and .05 was considered statistically significant. RESULTS AND CONCLUSIONS: It was found that the total number of whorls are significantly higher in patients with myocardial infarction and total number of loops are significantly lower in patients with CAD. Such difference was significant only in right thumb, left thumb, right ring finger and left little finger. Similarly, loops were significantly less in right thumb, right index finger, right and left little finger. With regard to high incidence of MI, it can be concluded that the knowledge of dermatoglyphics in patients with MI can be utilized to find out genetic correlation. The existence of such relation might be important in the screening program for prevention of MI.

Role of Dermatoglyphic Fingertip Patterns in the prediction of Maturity Onset Diabetes Mellitus (Type II)

Dermatoglyphic features are inherited by polygenic system with individual gene contributing a small additive effect. The present research aims to primarily study the various dermatoglyphic patterns in the patients of the Maturity Onset Diabetes Mellitus (Type II diabetes) and compare these statistically with the dermatoglyphic patterns in individuals not suffering from it. The present study was carried out on 101 (51 male and 50 female) clinically diagnosed patients of maturity onset diabetes mellitus. Healthy controls (n=100, 50 males and 50 females) were studied for comparison. Palmar prints were obtained in all the patients and controls and the dermatoglyphic patterns were analyzed using statistical considerations. Standard fingertip pattern configurations and landmarks were used in the study. Significantly higher frequency of arches and lower frequency of whorls were observed in female diabetics than controls. Dankmeijer's Index was highest in female diabetic group and Furuhata's Index was highest in the male control group. AFRC and TFRC were significantly lower in diabetic females than controls. Findings of the present study after a meticulous analysis of different fingertip dermatoglyphic variables highlights on the possible markers and indicate that there is scope for further study on a larger sample size.

A Cross-Sectional Study on the Palmar Dermatoglyphics in Relation to Carcinoma Breast Patients

Dermatoglyphics is a collective term for all the integumentary features (skin patterning of the fingers, toes, palms and soles) and it applies to the division of the anatomy which embraces their study. The purpose of this study was to examine the predominant finger tip patterns in the patients of carcinoma breast. An attempt is also being made to devise a score to assess the risk variables. The fingerprints of 100 carcinoma breast patients were obtained and they were compared with those of 100 females who were not suffering from any malignancy till date. The different quantitative parameters of each hand of both the cancer patients and the controls were studied. The parameters which were included were the fingertip ridge pattern, the ridge count in the individual fingers, the Total Finger Ridge Count (TFRC) and the Absolute Finger Ridge Count (AFRC). There was a significant increase in the arch pattern and a decrease in the radial loops in the right thumb (p<0.001), the left thumb (p<0.001), the left index finger (p<0.001) and the left middle finger (p<0.001). A comparison of all the five fingers of both the left and right hands of the cancer patients with the controls showed an arch pattern (p<0.001) with the highest frequency. The lower values of the TFRC (below 50) were associated with carcinoma breast .The lower values of the AFRC (below 100) were associated with the cancer patients. This study was able to establish a specific finger tip predominance in the Carcinoma breast patients.

Qualitative Dermatoglyphic Analysis of Finger Tip Patterns In Patients Of Oral Sub Mucous Fibrosis

Dermatoglyphics is the collective name for all those integumentary features within the limits to be defined and it applies to the division of anatomy which includes their study. Diagnosis of many diseases which are genetically or non genetically determined like Diabetes mellitus, Schizophrenia, Hypertension, etc can now be aided by dermatoglyphic analysis. Oral submucous fibrosis is a chronic precancerous oral disease, specially seen in guthka chewers, but not all the gutkha chewers develops the disease or non gutkha chewers may also develop the disease. Genetic predisposition explains such individual variability. Such genetic predisposition can be explored with the help of dermatoglyphic studies.100 gutkha chewers with Oral Submucous fibrosis and 100 Gutkha chewers without Oral submucous fibrosis were selected for the study and their qualitative dermatoglypphic analysis with specific reference to finger tip patterns was carried out and was statistically analyzed. Some highly significant patterns were observed in patients with Oral submucous fibrosis.

A Study of Dermatoglyphic Patterns in Epileptic Patients

The aim of study was to establish a relation of dermatoglyphic patterns of palm in epileptic and normal subjects so that it may be used as a diagnostic tool for identifying cases at risk. The dermatoglyphic study was carried out on 50 patients of epilepsy and 50 normal subjects. The dermatoglyphic traits, which presented a significant difference, were a-b ridge count, lateral deviation, c-line pattern, palmar pattern and finger tip pattern. Mean values of a-b ridge count were more in epileptic patients, especially in left hand, than controls. The ratio of ulnar and radial lateral deviation in control was 1:3 while in epileptic it was 1:5. C-line pattern presented less frequency of proximal and ulnar type patterns in cases. Radial type of C-line pattern was higher in cases. On the other hand this pattern was absent in 29% of controls than cases (8%). Arch type of palmar patterns were showing a very significant difference between controls (79%) and cases (2%). Frequency of loops were much more and vestiges were absolutely absent in cases. The frequency of Arch type of finger tip pattern was more in control. These findings suggest that antenatal factors may contribute to the etiology of epilepsy. A considerable progress in dermatoglyphics has been established as a useful diagnostic and research tool in medicine.

Dermatoglyphics in Patients with Dental Caries: A Study on 1250 Individuals

This study was undertaken to investigate and analyze the significance of dermatoglyphics in predicting the susceptibility of individuals to develop dental caries. This case-control study was conducted on 1250 children in the age group of 5 to 12 years from Chennai Corporation School, Vadapalani, Chennai. Out of 1250 subjects, 625 subjects were in the study group and the remaining 625 subjects were the control group. The study group included children with dental caries in 5 or more teeth based on the DMFT index performed and control group consisted of normal, healthy children without any dental caries. The finger and palmar prints of both hands were taken using a stamp pad. The fingertip patterns were analyzed according to the classical method and configurational types were classified according to the topological method. Statistical analysis was performed using nonparametric tests and t-test to compare the dermatoglyphic pattern changes between the study group and the control group and was applied for each variable, to compare the proportions, and p-value. (1) Dental caries susceptibility of an individual increases with an increase in the incidence of whorl pattern (83% correlation). (2) All the variables show statistically significant value, with a degree of divergence of specific dermatoglyphic patterns among study and control group. (3) The dermatoglyphic patterns are efficient and can predict in assessing the risk of susceptibility to dental caries in study group. The dental caries susceptibility of an individual increased with incidence of whorl pattern and it decreased with incidence of loop pattern. The dermatoglyphic patterns may be utilized effectively to study the genetic basis of dental caries. In a developing country like India, it might prove to be a noninvasive, inexpensive and effective tool for screening.
