ABSTRACT INTRODUCTION: Dermatoglyphic pattern formation and differentiation are complex processes which have been in the focus of research interest ever since dermatoglyphics became a science. The patterns’ early differentiation and genetic uniqueness as well as the relatively simple methods used to obtain and store fingerprints make it possible to study the relationship between certain dermatoglyphic characteristics and the underlying pathological processes in a number of diseases, including mental disorders. AIM: The present review reports published data from fundamental and clinical studies on dermatoglyphics primarily in schizophrenia and bipolar disorder to lend additional support for the neurodevelopmental hypothesis in the etiology of these disorders. Following an analysis of the theories of dermatoglyphics formation and the complex association between ridge patterns and central nervous system in early embryogenesis, an attempt is made to present dermatoglyphics as possible biological markers of impaired neurodevelopment. CONCLUSIONS: The contradictory data in the literature on dermatoglyphics in mental disorders suggest the need for further studies on these biological markers in order to identify their place in the neurodevelopmental etiological model of these diseases

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.

Dermatoglyphics is a study of the unique pattern in the skin of fingers, palms, soles, and toes. These dermatoglyphics has played an important role in various fields like forensic medicine, genetics, and anthropology.Sir Francis Galton stated that an individual’s dermal pattern remained constant throughout their lifetime. Many studies have suggested the possible relation between dermatoglyphics and occlusion.Studies have suggested that dermatoglyphics could be used as a tool to identify the underlying skeletal malocclusion. As the dermal pattern and oral structures develop together, the genetic information in the dermal pattern could be used to assess the different types of skeletal malocclusions. Hence, the study was aimed to compare and evaluate the correlation between dermatoglyphics and class II skeletal malocclusion in horizontal and vertical growth patterns. The total of 50 samples were taken and divided into horizontal and vertical growth pattern consisting of 25 samples each. The dermatoglyphic pattern between the right and left hand and the pattern such as arches, loops, and whorls were evaluated. The data was analyzed by Kolmogorov – Smirnov and Shapiro Wilk test. There was a statistically significant association between class 2 malocclusion and the dermatoglyphic pattern.

Dermatoglyphics (fingerprint) indicates epidermal ridge patterns of sole, palm, fingers, and toes. It is unique for each person, because it is determined by interaction of genes and intrauterine environment. Once dermatoglyphic patterns are formed, it is not affected by age, development, and environmental changes in postnatal life. Therefore, they exhibit positive values in predicting various genetically influenced disorders. Dermatoglyphics plays an important role in medicolegal, anthropology, and genetic studies. Diabetes mellitus, hypertension, Down syndrome, bronchial asthma, schizophrenia, and breast cancer are some of the diseases that can be screened by dermatoglyphic identification.

Background: Dermatoglyphics is considered, in the scientific milieu, to be an epigenetic marker. The objective of this study was to analyze the presence of dermatoglyphic marks characteristic of neuromotor capacity and abdominal resistance in children and adolescents. Methods: This is a cross-sectional study. The sample consisted of 1,002 individuals, female children and adolescents between the ages of 10 and 16, from public and private schools in the city of Joaçaba, Santa Catarina, Brazil. The protocol selected for analyzing the fingerprints was dermatoglyphics, proposed by Cummins and Midlo using a Dermatoglyphic Reader. The Brazilian Sports Project Manual - PROESP 2015 was used to collect data on muscle strength motor tests. Results: The results showed the presence of a dermatoglyphic mark characteristic of abdominal motor capacity and muscle strength in females. A higher frequency of arches was identified in MET4 and whorls in MET5 and MDT4 in the Risk Zone group. In the Healthy Zone group, ulnar loop was found to be more frequent in MET4, MET5, and MDT4 fingers. Conclusions: The results demonstrated a predictive marker for abdominal motor capacity and strength in females through dermatoglyphics.

Dermatoglyphics sterms from the ancient art of palmistry, which was practiced from time immemorial and is still followed throughout India by the Joshi caste. There appears to exist an extremely old volume, on the markings on the hands possessed and treasured by the Hindus. From here, this art has spread throughout the world.Essential hypertension is the category of hypertension that has no identifiable cause, it is associated with aging and inherited genetic factors. Positive family history increases the risk. Dermatoglyphic patterns are genetically determined and can be used as supportive for diagnosis of various hereditary disorders including essential hypertension. This study was carried out to compare palmar dermatoglyphic pattern in, essential hypertension and control group and compare with previous studies.A hospital based case control study was conducted 100 essential hypertensive patients 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 essential hypertensive patients compared with normal individuals.

Full textAbstract:
Dermatoglyphics is an integral part of the biological anthropology related to the studies of the population polymorphism and geographical variability of Homo sapiens. V.V. Bunak presented the dermatoglyphic methods in the chapter XI of "Anthropometry" too compact, the text needs some technical explanations, which was the purpose of this work. Materials and methods. We have combined the comments to the XI chapter of "Anthropometry" with a summary of the main concepts and terms of the accepted descriptive dermatoglyphic methodology. Results and discussion. The presentation of the dermatoglyphic methods in the XI chapter of "Anthropometry" contains 1) general remarks on technical equipment, 2) technique for obtaining prints, 3) topography of the relief and some dermatoglyphic traits. The main accent in the presentation of the method is on obtaining correct prints of the ridge skin for their further transcription and use in morphological analysis. The descriptive method of dermatoglyphics of the hand is partially present; the main attention is devoted to the explanation of general concepts (epidermal lines, radiant, triradius, type of pattern), the designations of features in the text and in the figures are minimal. There is practically no description of the dermatoglyphics of the soles. There are some terminological discrepancies in the description of some traits of the palms. Conclusion. The technique for obtaining prints of the skin of the palms and soles in "Anthropometry" by V.V. Bunak is still relevant today, however, the descriptive part is presented in fragments. Numerous data on dermatoglyphics had not yet been systematized in sufficient detail by the time "Anthropometry" was published, and an abbreviated form of the methodology was justified. The notes we have cited to the text of chapter XI of "Anthropometry" are specifying.

The dermatoglyphic collection (84 male and 62 female handprints) was collected as part of a genetic-anthropological expedition to the Pamirs (1984). Palm prints were taken using the ink method. The collection was processed according to the method of H. Cummins and Ch. Midlo. Finger and palm patterns were studied. The Cummins index and delta index were calculated. Circular polygons of signs of dermatoglyphics were built and the values of the Caucasian-Mongoloid complex were calculated. Literary data were used for comparative analysis. Results and discussion. As a result of the study, data on the dermatoglyphics of the Kyrgyz of the village of Dzhirgatal were introduced into scientific circulation for the first time. Frequencies of finger and palmar patterns in the studied group are presented. It has been shown that bilateral and sex differences in dermatoglyphic signs reflect general distribution trends. Constructed on the basis of key dermatoglyphic features, the combination polygons for the male and female groups of the Kyrgyz of Dzhirgatal, on the whole, have a shape characteristic of the Mongoloids, while revealing features of both the South Siberian and Central Asian local races. Conclusion. The results obtained clearly demonstrate that skin patterns are a source of historical and biological information, and dermatoglyphics greatly support the data obtained by other methods in anthropology, showing its high value for anthropological analysis, which is a prerequisite for further analysis of the studied group in terms of racial diagnosis and search for associations signs of dermatoglyphics and other genetically determined systems.

Introduction: Dermatoglyphics refers to the study of naturally occurring ridge on the planter surface of hand and foot of primates and other animals. Dermatoglyphics is a polygenic trait and is not duplicated among species even among monozygotic twins.The Ijaw’s are located predominately in the Niger Delta with fishing as their main stay of economy.Aim: To determine the frequency distribution and gender differences of dermatoglyphic patterns of the Ijaw ethnic group in Nigeria.Methodology: A total of 500 subjects were randomly selected to establish their digital and palmer dermatoglyphics by counting and classifying their ridge patterns based on standard technique.Results: The highest dermatoglyphic pattern frequency was radial loop (RL) 2.7±1.22, with least occurrence of ulnar loop pattern (UL) 1.37±0.60. There were no significant total finger ridge count (TFRC) and pattern intensity indices (PII) between sex P>0.05. Female subject had a significantly higher mean ATD angle and a-b ridge count than their male counterpart P <0.05.Discussion: There was a prevalence and elevated total frequency of radial loop and a diminution of whorl digital dermatoglyphic patterns; this finding is unique for this study population since most African studies among Nigeria ethnic group has ulnar loop as a predominate digital pattern. Also, sexual dimorphism was shown to exists in total finger ridge count (TFRC) and pattern intensity indices (PII) among the sampled subjects, however female subjects were reported to have higher mean ATD angle and a-b ridge count when compared to their male counterpart, this was statistically significant at P<0.05.Conclusion: This study has reported pattern frequency and gender asymmetry of digital and palmer dermatoglyphics traits of the Ijaw ethnic group.

Dermatoglyphics is the scientific study of the pattern of dermal ridges on the palmar surface of digits, palm and sole. Characteristically, hair does not grow in this area. These ridges serve well to enhance contact. The development of these ridges and the development of the nervous system occur simultaneously in the intrauterine period. The pattern of dermal ridges begins to develop around the 13th week and is completed by the 19th week of intrauterine life. Once the fingerprint pattern develops, it does not change and persists throughout life. Unusual dermatoglyphic patterns often relate to genetic disorders. Dermatoglyphics may be used as an additional screening tool to identify early risk factors that may help prevent additional complications of various diseases. In this review, we will be discussing dermatoglyphics and its important role in the diagnosis of diseases which have some genetic basis.

Introduction. Artificial neural networks are widely utilized in medical fields, such as dentistry, molecular genetics, immunology, cardiology, and others. Forensic medicine is no exception, as artificial neural networks are also beginning to find applications in this field.
The aim of this study was to demonstrate the potential for predicting human anthropometric parameters using dermatoglyphic parameters, which could enhance the method of dermatoglyphic identification.
Materials and methods. We analyzed dermatoglyphs of the hands and feet from 567 individuals aged 18 to 59 years, with no genetic or endocrine disorders and no musculoskeletal problems.
Results and discussion. The outcome of our work resulted in the development of the "Dermatoglyphics For Prediction (DFP)" program [Author's Certificate No. 74561. Computer program "Forensic Medical Identification Program using Artificial Neural Networks" Registration date: 07.11.2017]. This software device, after appropriate training, enables the prediction of an individual's ethnic-territorial affiliation and the presence of specific anthropometric parameters using such input data as dermatoglyphs of the hands and feet.
Conclusions. The increasing needs of the Ukrainian community for the identification of unknown individuals, given the geopolitical situation related to Russian invasion in Ukraine (the constant threat of ballistic missile attacks and unmanned aerial vehicles across the entire territory of Ukraine, which could lead to mass casualties), justify the relevance and the search for innovative approaches to dermatoglyphic identification expertise, utilizing state-of-the-art technologies, particularly neural network-based prediction of anthropometric parameters, sex, and ethnic-territorial affiliation of an unknown person, using input parameters such as dermatoglyphs of the hands and feet, with the aim of enhancing the evidentiary value of identification expertise. This software device, after appropriate training, allows for the prediction of ethnic-territorial affiliation and the presence of specific anthropometric parameters in the examined individual using such input data as dermatoglyphs of the hands and feet.

Abstract Our work has revealed a rather low level of similarity in regard to the finger dermatoglyphics of somatically healthy men, 19-35 years old, between Ukraine’s north and west, north and south, center and west, center and south, as well as the palmar dermatoglyphics between central regions and the east, center and west, center and south. The obtained finger/palmar dermatoglyphics did not differentiate administrative-territorial local groups of men between the north and the center, south and west (quantitative characteristics); or palmar – between the north and west, north and east, south and west, south and east, north and center. The differences between the administrative and territorial division of dermatoglyphic signs are a reflection of the historical and cultural differences induced by migration, as well as the intensive process of mixing, in addition to the isolation of particular groups.

ABSTRACT Background and Objectives: Dermatoglyphics is the study of fingerprints and skin patterns. During the intrauterine period, the development of dermatoglyphic patterns and dental hard tissues occurs at the same time. Dermatoglyphics has proved to be a potential tool in predicting dental anomalies. Hence, with the help of dermatoglyphics, we can explore the association between various dermatoglyphic patterns and types of malocclusion. Methods: A case–control study consisting of 150 children aged 12–14 years was selected. Based on the type of occlusion, the participants were grouped into skeletal class I normal occlusion (controls), skeletal class II malocclusion, and skeletal class III malocclusion. The fingerprints were analyzed using the ink method. The molar relation was determined according to Angle’s classification of malocclusion. The relation of fingerprints was studied with the molar relation recorded using the study models. Dermatoglyphic parameters were examined in these subjects. Results: In the study, it was observed that there was a notable increase in the occurrence of whorl pattern among patients with skeletal class II malocclusion (55%) and skeletal class III malocclusion (55.8%). On the other hand, in the skeletal class I group (controls), the frequency of loop pattern (66.6%) was found to be significantly higher. It was also noted that there was a slight decrease in the frequency of whorl patterns in skeletal class II patients as compared to skeletal class III patients. Conclusion: The whorl fingerprint pattern found in the study may indicate a higher likelihood of skeletal class II and III malocclusion in the general population.

The family character of atopic conditions, confirmed by many studies, has become the basis for the use of the method of dermatoglyphics to clarify the genetic nature of the “atopic march”. The purpose of the study was to identify differences in the features of palmar dermatoglyphics between patients with atopic dermatitis, allergic rhinitis and bronchial asthma. Primary indexes of palmar dermatoglyphics of young men and young women patients with atopic dermatitis, allergic rhinitis and bronchial asthma were taken from the data bank of the research center of National Pirogov Memorial Medical University, Vinnytsya. According to the method of Cummins H. and Midlo Ch. dermatoglyphic study of 320 young men and young women with allergic rhinitis (n = 69), bronchial asthma (n = 108) and atopic dermatitis (n = 143) was performed. Quantitative indices of palmar dermatoglyphics were subject to analysis. The results obtained were processed using the Statistica 6.1 license package using non-parametric methods. It is established that the differences of quantitative indices of palmar dermatoglyphics between young men / young women with atopic dermatitis and allergic rhinitis cover 50.0% / 66.67%; among patients with atopic dermatitis and bronchial asthma – 38.89% / 33.33%; among patients with allergic rhinitis and bronchial asthma – 22.22% / 55.56% respectively. Thus, in young men, the marker potential for signs of palmar dermatoglyphics in the prognosis for the development of bronchial asthma in the presence of allergic rhinitis (22.22%) or atopic dermatitis (38.89%) are insignificant compared with the prognosis for the development of allergic rhinitis in the presence of atopic dermatitis (50.0%). In young women, the marker features of palmar dermatoglyphics in the prognosis for the development of bronchial asthma in the presence of atopic dermatitis are insignificant (33.33%) compared with the prognosis for the development of bronchial asthma in the presence of allergic rhinitis (55.56%) and the prognosis for the development of allergic rhinitis (66.67%).

Introduction: Dermatoglyphics pattern is feature with which human takes birth. As a diagnostic aid, it is now well established in a number of diseases which have a strong hereditary basis. The aetiology of coronary heart diseases is believed to be multi-factorial with genetics playing an important role. Objective: The present study was designed to make an observation of the usefulness of dermatoglyphic pattern in serving as a predictor for myocardial infarction among Bangladeshi male who were non relative to each other. Place of study: The study was conducted in the Department of Anatomy, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh, between October 2003 and February 2005. Method: Inking method was used for taking finger and palm prints. Dermatoglyphic prints of five fingers and palm of both hands of sixty individuals were collected. Of them dermatoglyphic prints of both hands of 30 myocardial infarction (MI) male patients non relative to each other were selected as patients and same of 30 normal male having no myocardial infarction and having no family history of MI were selected as control. The dermatoglyphics of each hand of the patients were compared with those of the controls for: a) frequencies of different finger ridge patterns of the five fingers; b) total finger ridge count (TFRC); c) a-b, b-c, and c-d ridge counts of each hand; d) a-t-d angle; e) frequency of palmar ridge pattern and f) frequencies of different palmar creases. Result: The results of the controls confirmed more or less to the ethnic trends of the normal Bangladeshi. In case of finger dermatoglyphics, the MI patients showed higher frequencies of whorl patterns but lower frequencies of ulnar loop, radial loop and arch patterns than the controls. The mean total finger ridge count of the MI patients was lower than that of the controls (p>0.05). In case of palmar dermatoglyphics a-b, c-d ridge counts was higher and b-c ridge counts was lower in the MI patients than in the controls. Mean a-t-d angle was wider in the MI patients than that of the controls. Palmar patterns and creases showed no significant difference except transitional crease of the right hand that was significantly lower in MI patients than controls. Conclusion: Result of this study may be used to standardize the dermatoglyphic pattern of Bangladeshi population and to identify person susceptible to MI.

Full textAbstract:
Background: Dermatoglyphics can be utilised in clinical settings to identify those who are more likely to have impacted teeth. Additionally, dermatoglyphics looks to have potential as a non-invasive diagnostic method for predicting the presence or absence of an impacted tooth. The goal of this study was to look at the most common dermatoglyphic pattern in people who had or didn't have an impacted mandibular third molar teeth and see if there was a dermatoglyphic signature. Methods: A cross-sectional study with 180 participants was conducted (90 cases and 90 controls). The rolling impression technique was used to apply blue duplicating ink to participants' fingertips, which was then recorded. There was an increase in the frequency of the whorl-plain pattern in the right-hand ring finger (60%; p=0.028) and left-hand little finger (33.3%; p=0.009), as well as the loop-ulnar pattern in the right-hand middle finger (74.4%; p=0.024) in individuals with a predisposition to the presence of impacted teeth. Results: The left-hand little finger was found to be the most predictive for impaction in a forward stepwise binary logistic regression analysis. Conclusions: Dermatoglyphics could be used as a non-invasive sign to predict whether or not a tooth is affected. Its value comes in early detection, which helps to avoid the surgical problems that come with symptomatic extraction of an impacted tooth.

Background: Appreciable progress has been made to study and understand the associations between dermatoglyphics and numerous medical disorders, as a result of which dermatoglyphic analysis has been accepted as a useful diagnostic tool in many diseases particularly those are caused by chromosomal aberrations, which are frequently accompanied by distortion of patterns. Materials and Methods: The aim of this present work is to study the association between characteristic dermatoglyphic features in probands with jatyaandh due to congenital glaucoma compared with age sex matched control. Palmar dermatoglyphic analysis on 20 subjects was carried out. Dermatoglyphics prints were taken by ‘Ink method’ described by Cummins and Mildo, examined for Total Finger Ridge Count (TFRC), Absolute Finger Ridge Count (AFRC), (a-b) ridge count, atd, dat and adt angle (quantitative parameter) and Finger ridge patterns and their frequency (qualitative parameter). Further, statistical analysis is done to find the variations in the dermatoglyphic feature in both groups. Result: The mean values of TFRC, AFRC & atd angle were higher in case group than in controls. The mean value of a-b ridge count is lower in cases as compared to controls. The mean values of dat and adt angle of case group were almost same to that of control group. The highest pattern of distribution of whorls was found in cases whereas radial and ulnar loops are found in controls.

Essential hypertension falls in the category of hypertension that has no identifiable cause and affects 90-95% of hypertensive patients. Several studies have utilize dermatoglyphics as models for preliminary diagnosing diseases with genetic and non-genetic origins. However, little studies have been conducted to determine the relationship between dermatoglyphics and essential hypertension. The aim of the study was to generate detailed baseline data on the relationship between dermatoglyphic patterns and essential hypertensive to serve as a preliminary non-invasive diagnostic tool. A total of 400 participants out of which 200 were clinically diagnosed essential hypertensive patients from the Hypertensive Unit of Mampong Government Hospital (Ghana) and 200 clinically confirmed normotensive individuals were recruited for the present study. The fingerprints and palm prints of the participants were taken using a CanonScan Lide 120 colour image scanner which was connected to a Hp laptop. For the distribution of the sub-types of fingerprint patterns, ulnar loop dominated in both groups with the control group recording the highest. Statistically, there was no significant difference between the two groups. Significant difference was recorded between the two groups for the palmar ATD angle for both palms with the control group recording the highest. For the PIC patterns, PIC 300 and 310 dominated in both groups. Statistically, there was no significant difference between the two groups. The results of the present study have shown that, there is some relationship between dermatoglyphics and essential hypertension. This will serve as a preliminary diagnostic tool for the earlier diagnosis of the disease. KEY WORDS: Dermatoglyphics, Essential Hypertension, ATD angle, PIC pattern.

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.

Strengthening of global migration processes, often accompanied by an increase in crime and an increase in the number of unidentified individuals, necessitates the expansion of the use of indirect identification methods. In our opinion, involving dermatoglyphic analysis in cases of unidentified persons would help in forensic medical identification of the ethno-territorial membership of an unknown person. The purpose of the work is to identify a taxonomic complex of features of palmar dermatoglyphics at the local level that allow differentiating the regional affiliation of men in Ukraine. The study of dermatoglyphics of 400 virtually healthy men from 5 administrative-territorial regions of Ukraine was conducted using the method of H. Cummins and Ch. Midlo. Statistical processing of the results was carried out in the package “STATISTICA 6.1” using nonparametric methods. The set of signs of palmar dermatoglyphic was revealed, showing a high degree of heterogeneity between men from the following administrative-territorial regions of the country: central and eastern (20.0% of indicators), central and northern (16.9% of indicators), northern and western (16.9% of indicators), western and eastern (15.4% of the indicators) regions of Ukraine. Men from the northern and eastern (6.2% of the indicators), the south and west (6.2% of the indicator) and the southern and eastern (7.7% of the indicators) regions of Ukraine show a significant affinity for the features of palmar dermatoglyphics. In general, the high taxonomic value for intra-population differentiation of the local level have: the localization and saturation of the palm pattern, the size of the palm angles, the presence/absence of additional axial triads, the length of the segment c-t, the Cummins index.

Context: The word dermatoglyphics denotes as the scientific study of the epidermal ridge patterns of fingertips, palm and sole. There are three major classes of dermatoglyphic patterns of finger tips: loops, whorls and arches. Analysis of finger dermatoglyphic is beginning to prove itself as a useful tool for preliminary investigation in conditions with a suspected genetic basis. The genetic contribution is one of the causes of pulmonary tuberculosis. The present study on finger dermatoglyphics pattern was carried out to provide dermatoglyphic as a tool for early prediction of pulmonary tuberculosis by comparing dermatoglyphic patterns of pulmonary tuberculosis patients with the normal healthy individuals.
Materials and Methods: A Cross-sectional, analytical type of study was conducted in Department of Anatomy, Dhaka Medical College, Dhaka, from January 2012 to December 2012. The study was performed on 100 patients suffering from pulmonary tuberculosis and 100 healthy individuals.
Results: The percentage of whorl in pulmonary tuberculosis patients was significantly higher than control group (P<0.001). On the other hand, in pulmonary tuberculosis patients ulnar loop, radial loop and arch were 30.4%, 0.1% and 4.9% respectively and in control group were 72.3% , 2.5% and 10.3% respectively. Ulnar loop, radial loop and arch were significantly decreased in the patients group as compared to controls.
Conclusion: In the present study the percentage of whorl was predominantly higher in the pulmonary tuberculosis patient than the control subjects.

The work is devoted to the study of the variability of the main characteristics of the skin pattern of the fingers in boys and girls. The study involved 93 adolescents, including 52 girls and 41 boys. The dermatoglyphics of the fingers was studied according to the standard method with an assessment of the type of pattern and the overall intensity of the patterns. During the study, the following main phenotypes of digital dermatoglyphics were identified: 10L, AL, ALW, LW, 10W. Additionally, there were varieties of loop pattern: ulnar (elbow) loop - Lu; radial loop - Lr; double loop - 2L. The total intensity of the patterns was assessed by the DL delta index. In the examined group of adolescents, a study was made of the dermatoglyphic characteristics of finger patterns (type of pattern and its combinations, delta index, total scallop count, dermatoglyphic indices (finger pattern indices, pattern type indices) of Dankmeyer, Poll, Furugata and pattern intensity index), asymmetries of skin patterns and ridge count. The significance of differences between independent results obtained in the course of comparative analysis was determined using Student's t-test. The significance level was set at p<0.05. The distribution of types of patterns and their combinations on the nail phalanges of the fingers indicates that these characteristics of dermatoglyphics in girls have a simpler version compared to the dermatoglyphics of boys. The presence of pattern type W indicates a high probability that the fingerprints belong to young men, pattern type A - to girls. According to the frequency of occurrence of patterns on different fingers, a more frequent presence of arches in girls and curls in boys was revealed. The arc pattern is more often found on the second finger, but with different frequency (more often in girls), then on the third, fourth and fifth fingers. The loop pattern is more often found on the fifth, third and first fingers. Curls are more common on the fourth finger, then the second, third and first fingers in boys, and in girls on the fourth finger, then the second, first and third fingers, but with less frequency. Here it was possible to reveal a slight sexual peculiarity in the location of the curls: in boys the third finger, and in girls the first finger, but with a higher frequency in boys. The scallop count has a fairly large range of intragroup variability, especially among young men. The average values of the scallop count in young men are significantly higher, i.e. confirms the fact that this characteristic of dermatoglyphics in girls has a simpler variant (p<0.05). Asymmetry between the right and left hands in the surveyed groups of schoolchildren in this indicator was not revealed. A more pronounced phenomenon of fluctuating asymmetry of dermatoglyphic features in young men was found, manifested in such patterns as the ulnar loop and especially curls. Comparative analysis of the distribution by types of patterns and their combinations on the nail phalanges of the fingers, as well as the delta index showed that young men more often have more complex variants of these characteristics of dermatoglyphics. Therefore, a number of characteristics of the skin pattern of the fingers, such as the "arch", "ulnar loop" and "curl" phenotypes, their presence on certain fingers, as well as the level of the delta index and the asymmetry of skin patterns (ulnar loop and especially whorls) indicate that in the surveyed group of teenagers there are differences between boys and girls. The combination of these signs can be used for gender identification of a person.

ABSTRACT Introduction Dermatoglyphics is the scientific and analytical study of fingerprints. Every individual's fingerprints are distinctive; one can determine one's ingrained potential, individuality, and choices by interpreting dermatoglyphics. This twin-city survey was undertaken to evaluate the fingerprint patterns of children with dental caries [study groups – rampant caries vs early childhood caries (ECC)] and caries-free individual (control group). Aim This study was carried out to determine the correlation between dermatoglyphic pattern and caries prevalence in young children in the twin cities of Pune and Mumbai. Materials and methods Two centers were selected in Pune and Mumbai. A total of 300 patients (150 patients in each center) were randomly selected from the age group ranging between 3 and 5 years. The samples were divided into two groups: Group I: Caries group, and group II: Caries-free group. Group I was further divided into children with ECC and children with rampant caries. Clinical examination of dental caries was done using mouth mirror and probe (only to remove debris and not probe into the fissures) in daylight or suitable light source. Fingerprints were obtained by the conventional ink method. Statistical results were obtained by one-way analysis of variance with post hoc Tukey's correction for multiple group comparisons using Statistical Package for the Social Sciences version 20. Results The evaluation and comparison of patterns in children with caries and caries-free children in both right and left hands showed increase in the number of whorls in children with rampant caries as compared with children with ECC. However, this was not statistically significant. Conclusion The study showed a definite variation in dermatoglyphics between the ECC, rampant caries, and caries-free group. However, the rampant caries group showed more number of whorls as compared with the ECC group, but they were statistically insignificant. Dermatoglyphics has proven to be a useful, noninvasive, and cost-efficient tool for investigating diseases with a genetic background like dental caries and cleft lip and palate, etc. How to cite this article Chunawala Y, Morawala A, Ambiye A, Jain K.

ABSTRACT Introduction Dermatoglyphics is an extremely useful tool as a preliminary investigation method for diagnosing suspected genetic disorders. Caries being a multifactorial disease with the influence of genetic pattern, early identification of caries risk children with dermatoglyphics can help in using effective and efficient caries preventive measures. Aims and objectives The study was undertaken to record and know the frequency of occurrence of fingerprint patterns among children with caries and in children without caries. Materials and methods A total of 400 schoolchildren in the age group of 5 to 12 years were selected from a private school, Warangal, Telangana, India. Of 400 schoolchildren, 200 children were with caries group and 200 children were in caries-free group. Children with dental caries in five or more teeth based on the decayed, missing, filled teeth index performed were considered as study group, and the control group was normal healthy children without any dental caries. The fingerprints of each child were recorded using stamp pad method, and type of dermatoglyphic pattern of each digit was recorded based on Cummins and Midlo method. Data obtained were put for statistical analysis; p < 0.001 was considered statistically significant. Results Although the frequency of whorl pattern was more prevalent in caries group, it was statistically significant on the left hand third digit of females and on the right hand third digit and the left hand fourth digit of males. Fingerprints of female caries-free group showed maximum of ulnar loop and males showed maximum of arches. There was a decrease in total ridge count in caries group, especially in males. Conclusion Dermatoglyphics could be an appropriate method to explore the possibility of a noninvasive and an early predictor for dental caries. Clinical significance Dermatoglyphics has a future role in identifying people with or at increased risk for dental caries so that risk reduction measures or earlier therapy may be instituted.

Abstract. The article is devoted to the study of the phenotypic characteristics of persons prone to crimes against human life (murder), since there are currently no scientific works that would reflect the relationship of phenotypic manifestations in persons prone to illegal actions of varying degrees of severity, in particular, dermatoglyphic signs of all phalanges fingers and palms. In the course of the study, statistically significant differences were established between the dermatoglyphics of the persons who committed the murder and the dermatoglyphics of the persons of the control group.
The aim To determine the complex of dermatoglyphic parameters of fingers that make up the dermatoglyphic constitution of persons who committed murder.
Materials and methods of the study. 2 groups of people were studied: 1 group – corpses of people who committed murder (50 people); Group 2 - individuals of the control group (50 people), Research methods: dermatoglyphic, statistical analysis.
Results of the study. The dermatoglyphic characteristics of persons who committed murder have their own characteristics. The analysis of the dermatoglyphs of the fingers of the hands of persons who committed murder, in comparison with the control group, showed that on the fingers of the left hand radial loops (59.20%) and curls (26.80%) are most often found, arcs are less common (6.00%) ), complex patterns (4.40%) and ulnar loops (3.60%), a similar pattern is observed on the fingers of the right hand - radial loops (54.40%), curls (31.20%), arcs (5, 40%), complex patterns (5.00%) and ulnar loops (4.00%).With regard to the distribution of patterns on different fingers of the same person, it can be noted that the murderers had radial loops on the first fingers of the left and right hands most often - 64.00% and 44.00%, respectively, less often curls (24.00% and 42.00 %, respectively) and complex patterns (12.00% and 14.00%, respectively), ulnar loops and arcs did not occur at all on this finger on both hands; curls were most often found on the II fingers - 32.00% on the left and 34.00% on the right hands, as well as radial loops (30.00% and 22.00%, respectively), less often - ulnar loops (18.00% and 20.00% 00% respectively), arcs (16.00% each); radial loops (66.00% and 60.00% on left and right hands, respectively) and spiral patterns (18.00% and 28.00%, respectively) were most often found on III fingers, ulnar loops were not found on any hand; on the 4th finger of the left hand, radial loops (56.00%) and curl patterns (44.00%) were most often found, while on the right hand, on the contrary, curl patterns (50.00%) and radial loops (46.00%), the arc pattern was not met on this finger; on the V finger, the frequency of such patterns as radial loops (80.00% and 76.00%, respectively) and curls (16.00% and 24.00%) was almost the same on both hands, and ulnar loops did not occur at all.It should be noted that in the group of murderers there was no statistically significant difference in the distribution of the total frequency of patterns on the right and left hands (χ2 = 6.11, p > 0.1), as well as in CG men It should also be noted that there is a statistically significantly greater number of radial loops in killers than in CG men, on the fingers of both hands, with the exception of II (φІ = 3.78; φІІІ = 4.23; φІV = 4.63; φV = 5.30; p < 0.01), complex patterns on the I, II and IV fingers of the left hand (φI = 1.86; φII = 1.69, p < 0.05; φIV = 2.57, p < 0.01), curls on the first finger of the right hand (φІ = 2.37, p < 0.01), as well as a smaller number of ulnar loops on all fingers of both hands except II (φІ = 6.05; φІІІ = 6.73; φІV = 4 .42; φV = 7.39; p < 0.001).
Conclusions. In the course of the study, the presence of phenotypic (dermatoglyphic) signs characteristic of persons prone to crimes against human life was established.

Early detection and intervention strategies for schizophrenia are receiving increasingly more attention. Dermatoglyphic patterns, such as the degree of asymmetry of the fingerprints, have been hypothesized to be indirect measures for early abnormal developmental processes that can lead to later psychiatric disorders such as schizophrenia. However, previous results have been inconsistent in trying to establish the association between dermatoglyphics and schizophrenia. The goal of this work is to try to resolve this problem by borrowing well-developed techniques from the field of fingerprint matching. Two dermatoglyphic asymmetry measures are proposed that draw on the orientation field of homologous fingers. To test the capability of these measures, fingerprint images were acquired digitally from 40 schizophrenic patients and 51 normal individuals. Based on these images, no statistically significant association between conventional dermatoglyphic asymmetry measures and schizophrenia was found. In contrast, the sample means of the proposed measures consistently identified the patient group as having a higher degree of asymmetry than the control group. These results suggest that the proposed measures are promising for detecting the dermatoglyphic patterns that can differentiate the patient and control groups.

ABSTRACT Aim This study was undertaken to investigate and analyze the significance of dermatoglyphics in predicting the susceptibility of individuals to develop dental caries. Materials and methods 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. Results (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. Conclusion The dental caries susceptibility of an individual increased with incidence of whorl pattern and it decreased with incidence of loop pattern. Clinical significance 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.

Dermatoglyphic traits are genetically determined and remain constant until death. Dermatoglyphics features are arranged from patterns, minutiae and ridgeology. This study utilized patterns and minutiae details of fingerprints as a means of sexual differentiation amongst the University of Ibadan community. Three hundred and eighty-four (192 males and 192 females) participants from the University of Ibadan community were recruited using multistage sampling technique. Fingerprints were obtained using fingerprint scanner Dermalog LF10, Hamburg, Germany. GraphPad Prism 7.0 was used for the test of mean of variables. Ulnar loop, whorl and radial loop patterns were found to be predominantly distributed in both male and female in that order. However, the arch pattern was significantly different between female and male. The male subjects had significantly higher total finger ridge count (TFRC). All the analysed minutiae were significantly different between male and female except bridge. The arch pattern, TFRC and level 2 details (minutiae) of dermatoglyphics could be used as markers for sexual differentiation.

Dermatoglyphics is a method that makes it possible to detect potential physical capacities such as muscle strength, which is essential for sports performance and is also related to health outcomes. The aim of this study was to verify associations between dermatoglyphic marks and handgrip strength in men. The study included 367 men with a mean age of 23.79 ± 4.97. The handgrip strength was collected by a manual dynamometer and the dermatoglyphic variables using the Dermatoglyphic Reader® validated by Nodari Júnior et al., according to the protocol proposed by Cummins and Midlo. Data were analyzed using the Statistical Package for the Social Sciences (IBM SPSS) version 20.0, assigning a significance level of p <0.05. To verify the normality of the data, the Kolmogorov-Smirnov test was used. To verify differences between means, the Kruskal-Wallis test was used and for associations, the Chi-square test with adjusted residuals analysis. Superiority was observed in the means in MESQL1 and MDSQL1 among individuals with high handgrip strength in relation to those with low handgrip strength. Among the categorical variables, there was an association between the Ulnar Loop (UL) in the low strength group, the Arch (A) in the normal strength group and the Radial Loop (RL) in the high strength group, all in the MET2. It is concluded that dermatoglyphics can be used to identify individuals with low and high handgrip strength, enabling the detection and guidance of talents in sports, as well as individuals at risk of negative health outcomes.

The search for new psychodermatoglyphic correlations will greatly increase the possibilities of this method and will accelerate the introduction of scientific developments into the daily practice of clinicians, criminologists, police and other specialties. The purpose of the work is to establish the peculiarities of the relationship between the indexes of the finger and palmar dermatoglyphics and the characteristics of the personality traits of practically healthy Ukrainian men. From the data bank of the materials of the research center of National Pirogov Memorial Medical University, Vinnytsya were taken the primary questionnaires of indicators of personality characteristics and dermatoglyphic indicators of 92 practically healthy men residents of Podillia region of Ukraine in the third generation. Processing of indicators of finger and palmar dermatoglyphics was performed according to the method of Cummins H. and Midlo Ch. (1961) in the statement by Gladkova T. D. (1966). To assess the characteristics of personality characteristics we determined properties of temperament (according to Eysenck), anxiety (according to Spielberger), accentuated personality traits (according to Shmishek), motivational orientation of the personality (according to Rotter), as well as features of the emotional organization of personality, aggressiveness, level of personality manifestations (according to Luscher). Correlation analysis was performed in the “Statistica 6.1” license package using Pearson statistics. It has been established that in the majority of cases, indicators of personality traits and dermatoglyphic indices of almost healthy men show single direct and inverse, mostly weak forces (r=0.21 – 0.29 and r=-0.21 – -0.28, respectively) correlations. The multiple nature of such correlations is established only between the Luscher gray color index and the left hand I, III and IV fingers and the left hand I and II fingers ridge count, the total ridge count of both hands, the total ridge count and the left hand delta index (r=-0.23 – -0.28) and between most indicators by Rotter subjective scale and the presence of a pattern on the thenar of the corresponding palm (on the right hand – r=0.31 - 0.37 and on the left hand – r=0.22 - 0.29). The results of quantitative analysis of significant correlations showed that between the indexes of the finger dermatoglyphics and the indicators of personality traits according to Eysenck and Luscher, most relationships are inverse, and with Spielberger, Shmishek and Rotter – direct; between the indexes of the palmar dermatoglyphics and the indicators of personality traits according to Spielberger and Luscher, most reliable relationships are inverse, and with the indicators according to Eysenck, Shmishek and Rotter - direct. The results of the correlation analysis allowed us to determine the most significant relationships between the indexes of the finger and palmar dermatoglyphics and the characteristics of the personality traits of practically healthy Ukrainian men.

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. KEY WORDS: Fingerprint, Dermatoglyphics, Myocardial infarction, early diagnosis.

Aim: This study was conducted to evaluate and compare the prevalence of dermatoglyphic patterns amongst patients diagnosed with OPMD and a control group consisting of patients with/without tobacco habit, to prevent the occurrence of disease in susceptible individuals. Materials and Methods: Fingerprints were recorded using the Ink Method by Cummins and Midlo, and were subjected to analysis and statistical evaluation. Results: Fingerprints of a total of 150 patients were recorded amongst which each group i.e. subjects with OPMD, control with habit and control without habit consisted of 50 individuals. There was an equal distribution of whorl and loop pattern whereas arch pattern was found to be significantly less in number overall. Conclusion: Dermatoglyphics can be used for predicting various genetic disorders, when compared to environmental disorders, which are less case specific. In the present study there is no prevalence of individual pattern and it was found to be statistically insignificant, owing to the limited sample size. Studies in the field of dermatoglyphics among OPMD patients’ needs more research in order to draw recognizable and accountable conclusions.

ABSTRACT Fingerprint analysis for personal identification is well known, as it is unique to all individuals and remains unchanged over a life time. Now it is getting identified as a useful tool in understanding the basic questions in genetics and is emerging as an independent field in dentistry as dermatoglyphics. Dermatoglyphics are the dermal ridge configurations on the digits, palms and soles. Significant dermatoglyphics investigations have been carried for chromosomal disorders like Down syndrome, Turner syndrome, etc. The history, embryogenesis and topology of dermatoglyphics with emphasis on the various studies involving dermatoglyphics has been focused in this review.

Background: The role of genetic factors may be established by study of dermatoglyphics, therefore, any genetic abnormality during the formation of cleft lip and/or palate (CL/P) in the early trimester maybe reflected by altered dermatoglyphics. Aim: This study aims to assess altered dermatoglyphics in children with isolated, non-familial CL/P to understand the role of genetic factors in clefting.Methods: Case control study in a cranio-facial centre comprising of 40 infants (6-9 months) with CL/P and age and gender matched controls. Finger printing was done using black duplicating ink. A p-value of 0.05 was considered significant.Results: Majority (57.5%) had left sided clefting. Ulnar loops were the predominant digital pattern in the study group but there was no statistical difference with the controls, when all the finger patterns were considered together. There was significant difference in digital patterns in between the left thumb (p=0.033), ring (p=0.048) and little fingers (p=0.029) in the two groups. Comparison between the right and left hands within the study group showed significant difference in digital patterns in the thumb (p=0.047) and little finger (p<0.001). The study group also had a wider atd angle with significance (right hand p=0.038, left p=0.003) and a lower a-b ridge count with significance (right hand p= 0.045, left p=0.012).Conclusions: There was a definite dermatoglyphic difference specifically in the left hand, which was also the major side of clefting, within subjects as well as between subjects and controls.

The dermatoglyphic patterns of dermal ridges that constitute human fingerprint are formed during the early intra‑uterine life, between 7th and 21st week of gestation and mature at about seventh month of fetal development. Dermatoglyphics, once matured, remain unchanged throughout the life of an individual and are not influenced either by environmental or by age‑related factors. The heart and cardiovascular system develop between 4th weeks to 4th month of intrauterine life. So, any defect in heart development by any reason may affect development of dermal ridges.To study and compare the quantitative parameters of palmar dermatoglyphics of normal children with those of congenital heart diseases. It was a case control study conducted at Basaveshwara Hospital, Mahadevappa Rampure Medical College, Gulbarga and Jayadeva Institute of Cardiology, Bangalore. Children having congenital heart diseases (cyanotic and acyanotic) proven by echo-cardiography. Children with doubtful congenital heart diseases, Children with acquired heart diseases, Children with deformities of the hand. It is a Case-control study consisting 100 congenital heart disease patients and 100 controls. The atd angle in right and left hand, a-b ridge count in right and left hand of congenital heart disease children were significantly increased when compared to the normal children with p-value < 0.001. Distribution of Simian crease and Sydney line is statistically similar in two groups of children with p=1.000 Dermatoglyphics can be used as a predictive indicator about congenital cardiac diseases in population studies, easy to carry out with minimum time and expenses.

Heterogeneity by types of genodermatoses inheritance from the group of ichthyosis, which include virtually all possible variants, is the basis for the application of one of the genetic methods of human study - the method of dermatoglyphics. The purpose of the study is to determine the peculiarities of the quantitative indexes of finger and palmar dermatoglyphics in men and women with ichthyosis. Dermatological examination was performed in 49 patients with ichthyosis and 136 dermatologically healthy persons. The sample of patients was conducted randomly. All persons received informed consent for conducting observations. Fingerprint and palm prints are obtained by scanning fingerprints on paper by the Futronic's FS8 USB2.0 Fingerprint Scanner using the ftrScanApiEx.exe program, and then transferring data to a personal computer. Processing of dermatoglyphics data was carried out according to the method of Cummins H. and Midlo Ch. (1961). The quantitative indices of both finger and palmar dermatoglifics were determined. The calculation of the received results was carried out in the licensed software package “Statistica 5.5”. The average sample values (M) and dispersion (σ) were determined in the groups of the subjects surveyed. Using the Mann-Whitney U-test determined the probability of differences in the results obtained for individual groups. A certain complex of quantitative signs of palmar dermatoglyphics is revealed, which is characteristic for men suffering from ichthyosis, which includes indexes of the intensity of the comb formations, the value of the length of the segment c-t, the value of the palm corners and the Cummins index. In women suffering from ichthyosis, such a complex includes, as in men, indicators of the intensity of the combs and the length of the segment c-t, except for which - also the value of palm comb accounts. Given the specific lamellar form of ichthyosis, the dermatoglyphic picture (monomorphism of established signs on both hands: the presence of a single 4-finger flexural fold, a pattern in the III interdigital gap, low localization of the carpal angle atd, and the presence of the ulnar loop, complicated by the internal pattern on the III finger of the left and the IV the finger of the right hand brushes), the authors concluded that the study of ichthyosis should be carried out necessarily for each form of ichthyosis separately, which significantly increases the resolution of the method of dermatoglyphics.

Background: Schizophrenia is a psychiatric disorder encompassing multiple etiological variables. Association of dermatoglyphic traits with schizophrenia has been observed and reported. This study was undertaken to evaluate epidermal ridge patterns in patients of schizophrenia as compared to healthy controls attending a superspeciality hospital in West Bengal. Establishing dermatoglyphic parameters as biomarkers for early diagnosis will ensure prompt intervention and a greater scope of recovery in schizophrenia and thus promote a better quality of life for the individual as well as lower the burden of disease for the society.Methods: Quantitative dermatoglyphic parameters namely, total finger ridge count (TFRC), total A-B ridge count (TABRC) and ATD angle of 50 schizophrenia patients were compared to 50 age and gender matched healthy controls.Results: TFRC and TABRC were found to be decreased in schizophrenia, while ATD angle was increased in schizophrenia as compared to the control group.Conclusions: This study found a significant association between dermatoglyphic pattern anomalies and the development of schizophrenia. This may offer a scope of primordial prevention of schizophrenia in future, utilising dermatoglyphics as an investigative tool.

Dermatoglyphics is the scientific study of fingerprints, lines, mounts and shapes of hands, as distinct from the superficially similar pseudoscience of palmistry. Dermatoglyphics also refers to the making of naturally occurring ridges on specific body parts, namely palms, fingers, soles, and toes. These are areas where hair usually does not grow, and these ridges allow for increased leverage when picking up objects or walking barefoot. Learning new things and being an informative person have always been the goals of human beings, so coming to know about the human hand was also new information and created a great interest in individuals of various fields. Palms and soles of feet are covered with distinct classes of marks, So the study of fingerprints is called dermatoglyphics. Palmistry is called dermatoglyphics. The fingerprints patterns do not change throughout the lifetime. There are three types of significant fingerprints, Arches, loops, whorls. Dermatoglyphics is majorly used in an investigation. It also helps find a person’s uniqueness and helps in personalised education. The study aimed to assess the knowledge about dermatoglyphics among dental students. A questionnaire was designed online using google docs which consisted of 15 questions eliciting knowledge on dermatoglyphics. The study population included dental students. The responses were collected and statistically analysed. The results were partly biased, but on the whole, the dental students were aware of the basic details of dermatoglyphics. The survey concluded the dental students were partly aware, but at the end of the survey, they had got a clear idea about dermatoglyphics and its uses in different fields.

Aim: Dermatoglyphics appears during the 12th and 13th weeks of pregnancy and persists throughout life. Fingerprints are blueprints for one's personality; they can provide information about one's perception, emotions, intellect, and motivation. Dermatoglyphic is a non-invasive and low-cost method of obtaining illness information. The aim of this study was to see if there was a link between distinct fingerprint patterns and Frankl's behavior rating scale in children aged 6 to 12. Methods: A total of 52 participants between the ages of 6 and 12 years old received dental procedures and were scored using Frankl's behavior rating scale. Children were divided into three groups: Group 1: Whorl, Group 2: Loops, and Group 3: Arches. After scanning fingerprints of 10 fingers with a SecuGen Hamster Pro 20 biometric finger scanner, the resulting fingerprint pattern types were compared to Frankl's behavior rating scale. Results: Many non-cooperative participants had loop pattern fingerprints (46.4%), while most cooperative participants had whorl pattern fingerprints (58.3%). Conclusions: Children with a loop pattern fingerprint were more likely to receive a negative assessment. On the other hand, children with whorl patterns were more common among the positive participants. Keywords: Behavior Rating Scale; Dermatoglyphics; Pediatric Dentistry

Background: Genetics plays an important role in the detection of an Oral potentially malignant lesion. A major contributor to genetic study is Dermatoglyphics or the study of fingerprints and lines of palmer and plantar surfaces. Many researchers have used dermatoglyphics to connect genetics with oral lesions and malignancies. Thus, the current study has been conducted to find out an association between dermatoglyphic patterns and oral leukoplakia, oral submucous fibrosis and healthy subjects.Methods: The present study is conducted on subjects that have been already diagnosed with oral lesions. Fingerprint patterns (whorled, loop and arch) were evaluated by utilizing fingerprints.Results: The present study showed that the loop pattern was common in all three subjects. The frequency of whorled and arch pattern is decreased in oral leukoplakia and oral submucous fibrosis that healthy subjects. Arch pattern is comparatively decreased in subjects with oral leukoplakia than oral submucous fibrosis and there is a decrease in the frequency of whorled patterns in OSMF as compared to oral leukoplakia.Conclusions: Authors conclude that simply by observing the whorled and arch patterns in a subject, authors can hypothesize that risk of occurrence of oral leukoplakia and oral submucous Fibrosis and take preventive measures against the said lesions.

Background: Dermatoglyphics is an indispensable tool in the field of Forensic Science and Criminology and its various unknown aspects are being explored in other fields. They are important in genetics because of their usefulness in diagnosing some dysmorphic syndromes like Down Syndrome, Turner Syndrome etc.Methods: A hospital based descriptive study was carried out in the Institute of Child Health, Madras Medical College, Chennai from January 2015 to September 2015. Children admitted with major congenital malformation diagnosed either clinically or with imaging were included in the study.Results: 125 children with congenital malformation were included in the study. This included 65 cases of congenital heart disease, 20 cases of congenital talipo equino varus, 15 cases of cleft lip/palate, 15 cases of genetic syndrome and 10 cases of CNS malformations. Loops (64.3%) were the most common pattern in CHD followed by whorls (31.5%). In the CTEV group, loops (57.65%) were the most common pattern followed by whorls (36.48%). Ulnar loops (50.32%) was more common in Down’s Syndrome whereas arches (46.37%) were more common in Edward’s Syndrome. Frequency of whorls (53.28%) was higher in children with CNS malformations.Conclusions: Congenital malformations are associated with abnormal dermatoglyphics patterns. Patterns such as loops are common in CHD and syndromic children whereas whorls are common in children with CNS malformations. Large population study with a well-matched control may bring out definite dermatoglyphic pattern for many congenital disorders. They may serve as a simple diagnostic tool for these disorders.

Full textAbstract:
Dermatoglyphics, ridge constellations on the hands and feet, are permanently formed by the second trimester of pregnancy. Consequently, they are considered “fossilized” evidence of a specific prenatal period. A high frequency of dermatoglyphic anomalies, or a high rate of dermatoglyphic asymmetry (discordance), is an indication of developmental instability (prenatal disturbances) prior to 24-week gestation. Most dermatoglyphic studies in psychiatry focus on adult schizophrenia. Studies on dermatoglyphic deviances and autism are sparse, include severely disturbed and intellectually retarded patients with autism, and are carried out mainly in non-Western European populations. In this study, finger print patterns, atd-angles, and palmar flexion crease patterns (PFCs) are compared between Western European adolescent teenage males, of average intellect, with Autism Spectrum Disorders (ASD;n=46) and typically developing adolescent teenage males (TD;n=49). Boys with ASD had a higher rate of discordance in their finger print patterns than TD boys. Thus, the hypothesized prenatal disturbances that play a role in the etiology of schizophrenia and severe autism might not be specific to these severe psychiatric disorders but might also be involved in the etiology of varying degrees of ASD.

Dermatoglyphics is the scientific study of the epidermal ridge configuration of hands and feet. Digital dermatoglyphics are unique and specific evidence that greatly contribute to personal identification in forensic science. Hand dominance is an uneven distribution of fine motor skills between the left and right hands. The objective of the study is to observe gender variation in fingerprinting pattern of thumb and index fingers and also to determine the relationship between handedness and digital dermatoglyphics. The study was conducted at Saveetha Medical College and Hospital. Ethical clearance for this study was obtained from the Ethical Clearance Committee of the institute. This cross-sectional study was conducted on a sample size of 500 students, of 18-25 years of age, pursuing their education in the constituent courses of Saveetha Medical College. Handedness was assessed using the Edinburgh Handedness Inventory. The fingerprints were obtained by a 'Lipstick' method. The prints were studied using a magnifying lens. The various patterns of fingerprints were observed, categorized and compared according to standard guidelines. A total of 500 students were studied. There were 228 right-handed males, 18 left-handed males, 233 right-handed females and 21 left-handed females. In right-handed males, the thumb showed a predominance of loop pattern in (57.9 %) study participants and in right-handed females loop pattern was observed in thumb was 61.1%. In the right-handed female thumb, loops were predominant patterns in 70.8. Arch pattern is distinctively absent for both right and left-handed thumb in both males and females. 19.3 % of female right-hander had arch patterns predominantly in their index finger. Widespread interest is developing in the field of medicine and forensic science with regard to epidermal ridges. Our present study was able to observe gender variations and variations in the dermatoglyphic pattern in the right and left-hander for the first two digits.

ABSTRACT Dermatoglyphics refers to epidermal ridges present on the palm, sole, fingers, and toes. These epidermal ridges are formed in the same intrauterine period when neuronal development takes place in the intrauterine life of a fetus. Thus, dermatoglyphics is correlated with genetic abnormalities and is useful in the diagnosis of congenital malformations and many other medical disorders. Each and every individual has unique fingerprints, even in twins. These fingerprints remain the same lifelong from their development unless they are damaged by dermal injuries. The different regions of our brain are reflected by fingerprints, palm prints and foot patterns present in the 10 fingers, 10 toes, palmar and plantar surfaces respectively and these dermatoglyphics represent the various regions of brain therefore can be used in dermatoglyphics mental intelligence test (DMIT) and now a day is being used globally.

The study aimed at examining differences in digital dermatoglyphics distribution between fertile and infertile women in Abuja, Nigeria. A total of 222 women with 53 clinical cases of primary infertility were included in this study. Dermatoglyphic patterns of the distal phalanges were obtained for further analyses of quantitative and qualitative traits. The results showed a lower incidence of loop patterns (55%), and a higher incidence of arches (7%) and whorls (29%) in infertile women than in fertile ones. Infertile women showed a unique and specific digital pattern distribution on each of the fingers on the right and left hand. A significant decrease in ridge count (RC), total finger ridge count (TFRC) and absolute finger ridge count (AFRC) was observed in the infertile patients (p<0.05) in relation to fertile women. 2D:4D index in infertile and fertile women was 0.95 and 0.85 respectively. The observed differences in the digital traits could provide a useful bio-indicator for genetic counselling among reproductive age women.
