The Study Of Dermatoglyphics Pattern In Females With Primary Infertility

Background: Dermatoglyphics, the study of fingerprint ridge patterns, has been recognized for its potential in reflecting genetic and developmental variations. Primary infertility, defined as the inability to conceive after a year of regular, unprotected intercourse, is influenced by genetic, hormonal, and environmental factors. This study aims to investigate dermatoglyphic patterns in females with primary infertility to explore possible correlations between these patterns and infertility, providing insights for early diagnosis and management. Objective: The primary objective of this protocol is to systematically analyze dermatoglyphic patterns in females with primary infertility and compare them with those of fertile females. The study seeks to identify specific fingerprint characteristics that may serve as non-invasive markers for primary infertility. Methodology: This cross-sectional study will include two groups: females diagnosed with primary infertility and age-matched fertile controls. Dermatoglyphic data will be collected using the ink method, and the following parameters will be analyzed: total ridge count (TRC), patterns of arches, loops, and whorls, and other key qualitative features. Statistical analysis will be performed to evaluate significant differences between the two groups. Expected outcome: The study is expected to reveal distinct dermatoglyphic patterns in females with primary infertility compared to fertile females. Identifying such patterns may provide valuable markers for assessing genetic predispositions and could potentially assist in early diagnosis and personalized treatment strategies for infertility. Conclusion: This protocol outlines a method for studying the potential role of dermatoglyphic patterns in primary infertility, proposing a non-invasive, cost-effective diagnostic approach. Further research may help in establishing dermatoglyphics as a supplementary tool in infertility assessment and managemen.

The Study of Dermatoglyphic Patterns in Females with Primary Infertility: A Case-Control Study in the Maharashtra Population

Introduction: Dermatoglyphics is a widely known technique applied in genetic and medical research for the examination of finger, palm, and sole patterns. Dermatoglyphic characters are formed in the fetal stage and remain unaltered throughout their life. Some previous studies have indicated that dermatoglyphic patterns are linked with some reproductive disorders, like primary infertility. This study focuses on the evaluation and comparison of the dermatoglyphic patterns of females with primary infertility and healthy controls in the Maharashtra population. Methods: It involves a case-control study on two hundred females diagnosed with primary infertility and two hundred age-matched healthy controls. Several dermatoglyphic patterns were found, including total ridge count (TRC), atd angles, loops, whorls, and arches, which were assessed and compared among the groups. Results: When compared to the control group, the dermatoglyphic patterns of the infertility group were significantly different. Whorls and arches were more common in this group, and loops were less common. Furthermore, the infertility group exhibited a higher mean atd angle value and a lower total ridge count in comparison to the control group. Conclusion: Certain dermatoglyphic features correlated with female primary infertility in Maharashtra have been identified. These results can be taken as a precursor to further research work on the genetic basis of infertility and also with regard to whether dermatoglyphics can be used as a diagnostic tool.

Genetic and Neurodevelopmental Markers in Schizophrenia-Spectrum Disorders: Analysis of the Combined Role of the CNR1 Gene and Dermatoglyphics.

Background: Dermatoglyphic pattern deviances have been associated with schizophrenia-spectrum disorders (SSD) and are considered neurodevelopment vulnerability markers based on the shared ectodermal origin of the epidermis and the central nervous system. The endocannabinoid system participates in epidermal differentiation, is sensitive to prenatal insults and is associated with SSD. Objective: We aimed to investigate whether the Cannabinoid Receptor 1 gene (CNR1) modulates the dermatoglyphics-SSD association. Methods: In a sample of 112 controls and 97 patients with SSD, three dermatoglyphic markers were assessed: the total palmar a-b ridge count (TABRC), the a-b ridge count fluctuating asymmetry (ABRC-FA), and the pattern intensity index (PII). Two CNR1 polymorphisms were genotyped: rs2023239-T/C and rs806379-A/T. We tested: (i) the CNR1 association with SSD and dermatoglyphic variability within groups; and (ii) the CNR1 × dermatoglyphic measures interaction on SSD susceptibility. Results: Both polymorphisms were associated with SSD. The polymorphism rs2023239 modulated the relationship between PII and SSD: a high PII score was associated with a lower SSD risk within C-allele carriers and a higher SSD risk within TT-homozygotes. This result indicates an inverse relationship between the PII and the SSD predicted probability conditional to the rs2023239 genotype. Conclusions: These novel findings suggest the endocannabinoid system's role in the development and variability of dermatoglyphic patterns. The identified interaction encourages combining genetic and dermatoglyphics to assess neurodevelopmental alterations predisposing to SSD in future studies.

Dermatoglyphic pattern is an Indicator for Assessing the Intelligence Quotient (IQ) of Medical Undergraduates in A North Indian Medical College

Introduction: The intelligence quotient (IQ) levels and dermal ridge patterns on the volar surfaces of digits and palms of different individuals may be related because brain developed from 13th to 21st week and during same time-period the dermal groove developed. Neocortex is a higher center for learning and of intelligence, so there is association between Intelligence level and patterns of fingerprints. So, this study was conducted to find out the different dermatoglyphic patterns of fingers and palms and correlate them to the IQ levels of medical undergraduates. Materials and Methods: Fingers and palms prints of both the hands of 150 medical students of 18-24 years were collected with help of ink pad and A4 size of paper. The fingers and palms prints were studied using hand held magnifying lens and their IQ levels assessed using Raven’s Standard Progressive Matrices. Results: The most common finger patterns e.g. single whorl in thumb, ulnar loop in index finger and middle finger of both sides and were found on participants having Grade I Intelligence. More males shown higher IQ and belonged to Class A IQ i.e. grade I and Grade II however in lower IQ the males and females were equally distributed and belonged to Class B i.e. Grade III, IV, V. Most common finger patterns i.e. single whorl in thumb and ulnar loop in index on both right and left side were found in the participants having Grade I & II Intelligence. Conclusion: Students with Grade I and II IQ has higher incidence of whorl followed by loop whereas in participants with IQ level of Grade III onwards, loop was the most common pattern followed by whorl. Asymmetry in patterns on both the side of fingerprint was evident in lower IQ levels. Higher values of mean ‘a-b’ ridge count and mean ‘atd’ angle was higher in individuals with low IQ level. So, it can be concluded that the dermatoglyphic pattern and IQ levels are associated.

Sexual dimorphism of dermatoglyphic features in Type 2 diabetes mellitus patients of West Bengal: A cross-sectional study

Background: Dermatoglyphics is the study of epidermal ridge patterns on the fingers, palms, and soles. Correlation of dermatoglyphic patterns with many chromosomal abnormalities and genetic predisposing diseases such as diabetes mellitus, hypertension, schizophrenia, and bronchial asthma is evidenced by many researchers. Literature on sexual dimorphism of dermatoglyphic patterns revealed it as an important characteristic feature. Aims and Objectives: The aim of the study is to study the variance of ridge patterns among male and female patients of Type 2 diabetes mellitus patients of West Bengal and determine the sex-specific digital and palmar ridge patterns in Type 2 Diabetes mellitus. Materials and Methods: A cross-sectional study has been done on 100 male and 100 female Type 2 diabetes mellitus patients. Digital and palmar prints were taken by the traditional ink method. Digital ridge pattern, pattern intensity index, total finger ridge count (TFRC), absolute finger ridge count (AFRC), and a-b ridge count were studied. The data on these patterns was recorded and statistically analyzed by Chi-square test and Student’s t-test. Results: The frequency of ulnar loop is higher in female diabetics in comparison to male diabetics. Statistically significant increase in mean TFRC and mean AFRC is seen in male diabetics. Conclusion: Our study exhibits that dermatoglyphic pattern significantly differs in male and female diabetics. The knowledge and reference range of dermatoglyphic parameters among male and female diabetics are essential in the use of this study as a screening tool or diagnostic tool in Type 2 diabetes mellitus.

Dermatoglyphic palmar pattern variations in congenitally deaf and mute subjects

Background: Dermatoglyphics have the unique merit of retaining all their peculiarities unchanged throughout life, and afford in consequence an incomparably surer criterion of identity than any other bodily feature. The rationale for studying dermatoglyphic features is derived from the fact that development of dermal ridges and congenital deafness seems to develop at around the same time. Methods: The material for the study consisted of palm prints of congenitally deaf and mute children of 100 subjects with congenital deafness and muteness between 5-21 years of age and 50 control of similar age group with normal hearing and speech were chosen. The principal patterns of thenar/ I interdigital, interdigital II, interdigital III, interdigital IV and hypothenar area were noted. Position of axial triradius, ‘atd’ angle, pattern of palmar Flexion Creases, presence as well as pattern of the Simian Line and the Sydney Line were recorded. Results: The percentage of open field was maximum in subjects in thenar / interdigital area I. and in interdigital area IV. The mean a-b, c-d and atd angle ridge palmar ridge count was less in subjects in comparison to controls. Highly statistically significant results were obtained between subjects and control for the simian crease pattern when both hands were considered together in which the percentage of transitional type was more than the typical simian crease in subjects. Conclusion: When combined with other clinical and investigative features, dermatoglyphic study can serve as a diagnostic impression and can be advocated as a useful screening device.

Correlation of palatal anatomic characteristics with dermatoglyphic heterogeneity in different growth patterns

The study aimed to explore the correlation between dermatoglyphic patterns and quantitative palatal anatomic variables in individuals with different growth patterns. A cross-sectional study was conducted involving 126 healthy patients aged 17-25 years. Participants were divided into three groups based on growth patterns: average, vertical, and horizontal. Dermatoglyphic patterns were recorded using an optical fingerprint sensor, and palatal characteristics were measured using digital software. Palatal characteristics, including intercanine width, intermolar width, and palatal depth, were measured using digital software. The results were statistically analyzed. Significant differences were observed in ridge counts among the three growth patterns. The average growth pattern showed lower ridge counts compared to the vertical and horizontal growth patterns. Dermatoglyphic patterns, such as double loops and tented arches, were significantly higher in the horizontal growth pattern. Weak correlations were found between certain dermatoglyphic patterns and palatal characteristics, with simple arch patterns showing a negative correlation with inter-canine width and symmetrical whorl patterns showing a positive correlation with palatal depth. Loop patterns, spiral patterns, double loop patterns, symmetrical whorl, and simple arch patterns were significant predictors of growth patterns. This study revealed distinct dermatoglyphic patterns and ridge counts among individuals with different growth patterns. Weak correlations were observed between dermatoglyphic patterns and palatal characteristics. However, the predictive value of dermatoglyphics for skeletal malocclusion requires further investigation. Understanding the relationships between dermatoglyphic patterns and craniofacial growth can provide valuable insights into genetic and developmental factors affecting dental and orthodontic conditions.

A STUDY ON FINGERTIP DERMATOGLYPHIC PATTERN IN PATIENTS WITH MYOCARDIAL INFARCTION IN THE NORTH INDIAN POPULATION

Objectives: Myocardial infarction is one of the rising heart ailments causing mortality and morbidity around the world and especially in the north Indian population. In earlier studies, it has been found that dermatoglyphics and myocardial infarction have a correlation due to genetic disposition. The present study is based on the same hypothesis to find out such a relation and its uses as an economical diagnostic tool. Methods: The present study was conducted after taking informed consent forms from 150 patients with myocardial infarction as cases, whereas 150 normal health individuals were included in the study as controls. Fingerprints were taken using the method described by Cummin and Mildo. Result: The study found that the different fingerprints which are whorls, arches, and loops have a specific pattern that differs in myocardial infarction cases and control. In some cases, the loop and whorls have been increasing, whereas the arches were found to be decreasing as compared to controls. The mean total finger ridge count (TFRC) and absolute finger ridge count (AFRC) have been found to decrease in both males and females and the decrease was statistically significant. Conclusion: Dermatoglyphics and myocardial infarction have shown a close correlation due to genetic association. Thus, it can be used as one of the cost-effective diagnostic tools for myocardial infarction.

Study of the fingerprints of a Spanish sample for the determination of the hand and finger

The individuality and permanence of fingerprints make of them a very useful feature in the identification of individuals. There are now automated computer programmes that allow a quick comparison between a fingermark and a database. However, in order to assess the strength of evidence in fingerprint identification, complementary information on the frequencies of the different morphological features of the dermopapillary ridges is required. This idea is used in this work as a starting point to evaluate the frequencies of the parameters used in the determination of the hand and finger in a large sample of 2600 fingerprints taken from 134 male and 127 female Spanish population. Based on these fingerprints, the frequencies of different categories of the following parameters were obtained: type of pattern, slope of the apex ridge, subtype of two-delta pattern, ridge tracing, major angle, major ridge count, bisector, rotation of the central ridge, assimilation to loops and slant. Moreover, the results have shown that these characters are useful for the determination of the hand in whorls (two-delta pattern) and loops (one-delta pattern), but not for the determination of the finger. The most useful and classificatory parameter when determining the hand of origin of a two-delta fingerprint is the slope of the apex ridge, and for the one-delta pattern, knowing the location of the delta allows the correct estimation of the hand of a fingerprint in more than 93% of the cases. The data presented in this paper are novel and can be used by latent print examiners to improve the statistical basis of their decisions in reaching conclusions.

Dermatoglyphic Patterns in Undergraduate Medical Students and their Association with Academic Performance: A Cross-sectional Study

Introduction: Dermatoglyphics is the study of fingerprint patterns, which are unique to each individual and remain unchanged after birth. It has been used in criminology for decades. In recent years, its role in screening various medical conditions has been established. Dermatoglyphics has also been associated with cognitive ability, making it a potential predictor of academic potential. Aim: To investigate the association between dermatoglyphic patterns and the academic performance of medical students. Materials and Methods: A cross-sectional study was conducted in the Department of Anatomy, Jawaharlal Nehru Medical College, Wardha, Maharashtra, India on 200 undergraduate medical students (94 males and 106 females) from January 2019 to December 2020. Fingerprint patterns were obtained using the standard ink method. The parameters studied included arches, loops, whorls, composites, Total Finger Ridge Count (TFRC), and the 'atd' angle. The academic performance of participants was assessed based on the marks obtained in the National Eligibility Cum Entrance Test (NEET) and the overall marks scored in the first-year university examination. Statistical analysis involved the use of arithmetic mean, standard deviation, Chi-square test, and one-way Analysis of Variance (ANOVA). Results: In present study, the most common fingerprint pattern in the right hand was an arch (30.9%), followed by a whorl (24.5%). In the left hand, the most common fingerprint pattern was a whorl (40.6%), followed by an ulnar loop (20.1%), with no gender difference observed. Thumb, index finger, middle finger, ring finger, and little finger exhibited different fingerprint patterns between the right and left hand, indicating asymmetry. This asymmetry was associated with lower academic performance. Higher academic performers in the NEET had a higher frequency of whorls and composites. TFRC showed no association with academic performance. Students with an ‘atd’ angle between 41 and 50° demonstrated higher academic performance. Conclusion: The present study found that asymmetry of fingerprint patterns and a higher ‘atd’ angle (≥51°) were correlated with lower academic performance among medical students. These findings suggest potential directions for early academic intervention, provided multicentric studies are conducted in the future.

Automated fingerprint analysis as a diagnostic tool for the genetic disorder Kabuki syndrome

PurposeEmerging therapeutic strategies for Kabuki syndrome (KS) make early diagnosis critical. Fingerprint analysis as a diagnostic aid for KS diagnosis could facilitate early diagnosis and expand the current patient base for clinical trials and natural history studies. MethodFingerprints of 74 individuals with KS, 1 individual with a KS-like phenotype, and 108 controls were collected through a mobile app. KS fingerprint patterns were studied using logistic regression and a convolutional neural network to differentiate KS individuals from controls. ResultsOur analysis identified 2 novel KS metrics (folding finger ridge count and simple pattern), which significantly differentiated KS fingerprints from controls, producing an area under the receiver operating characteristic curve value of 0.82 [0.75; 0.89] and a likelihood ratio of 9.0. This metric showed a sensitivity of 35.6% [23.73%; 47.46%] and a specificity of 96.04% [92.08%; 99.01%]. An independent artificial intelligence convolutional neural network classification-based method validated this finding and yielded comparable results, with a likelihood ratio of 8.7, sensitivity of 76.6%, and specificity of 91.2%. ConclusionOur findings suggest that automatic fingerprint analysis can have diagnostic use for KS and possible future utility for diagnosing other genetic disorders, enabling greater access to genetic diagnosis in areas with limited availability of genetic testing.

The Use of Levels One and Two Dermatoglyphics for Sex Identification in University of Ibadan Community, Southwest Nigeria.

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.

Variations in fingertip dermatoglyphic pattern in congenitally deaf and mute subjects

Background: Dermatoglyphics, the scientific study of the origin, development and variation on dermal ridges and patterns on the fingers, palms and soles have been employed to observe association with many congenital defects and genetic diseases. Development of dermal ridges and congenital deafness seems to be interlinked as they develop at about the same time. Methods: The material for the study consisted of finger and palm prints of congenitally deaf and mute children of 100 subjects with congenital deafness and muteness between 5-21 years of age and 50 control of similar age group with normal hearing and speech were chosen. Digital patterns, triradii, total ridge count were noted. Results: Overall fingertip pattern of subjects and control when right and left hands were considered together showed significant results in which there was maximum percentage of ulnar loops followed by whorls, carpal arches, composites and least were the tented arches in the subjects. Mean ridge count of all the digits comes out to be less in subjects in comparison to control but it was not statistically significant. Conclusion: Dermatoglyphics can serve as a simple, inexpensive screening tool but further preliminary investigations are needed to come to a conclusive finding.

Palmar dermatoglyphic profile in Jatyaandh - A Pilot Study

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.

QUANTITATIVE DERMATOGLYPHIC PATTERNS IN FEMALE BREAST CANCER PATIENTS

Purpose: Recently, quantitative dermatoglyphic examinations have been intensively carried out for screening purposes in oncology. Material/Methods: The present study covered 82 women aged between 36 and 80 years with clinically, histologically and mammographically confirmed breast cancer and 60 healthy women aged between 31 and 79 years from the region of Varna, Bulgaria. Two dermatoglyphic methods were applied: i) dactyloscopy of finger ridge count and finger indexes and ii) palmoscopy - palmar ridge count, palmar maximal atd, adt and dat angles, and palmar main lines. Statistical data processing was performed by means of variation analysis, regression analysis, χ2 test and one-way ANOVA using the SPSS software package, version 19. Results: The results from the dactyloscopic and palmoscopic examinations revealed several statistically significant differences in these quantitative dermatoglyphic patterns between breast cancer females and healthy ones. Conclusion: We could conclude that the purposeful examinations of the quantitative dactyloscopic patterns such as total finger ridge count and finger indexes and quantitative palmoscopic traits such as palmar ridge count, maximal adt, atd and dat angles and main palmar lines play a promising role for the cost-effective and trustworthy breast cancer screening in Bulgaria.

Digital-palmar dermatoglyphics characteristics of patients living with schizophrenia in Ghana

The World Health Organization has acknowledged the gap in schizophrenia diagnoses and recommended further research to identify tools and biomarkers for the disease’s early detection. Because the skin and brain have a common ectodermal origin, dermatoglyphics are hypothesized to serve as a potential mirror for the identification of risks and characteristics of neuropsychiatric diseases. This study aimed to determine the digito-palmar dermatoglyphic patterns of schizophrenia patients in Ghana. Digito-palmar dermatoglyphics were obtained using a digital scanner, and the details studied. Individuals living with schizophrenia in Ghana were significantly characterized by low odds of vestige pattern in the hypothenar region, low odds of palmar creases 300, and high and low odds of radial loop (RL) and plain arch (PA) respectively at the finger patterns relative to the control group [OR (95% CI): vestige, 0.2 (0.06–0.69), P = 0.01; palmar creases 300, 0.1 (0.01–0.99), P = 0.049; PA, 0.4 (0.3–0.7), P < 0.001; RL, 1.9 (1.0–3.7), P = 0.044]. Individuals with schizophrenia were also characterized by low mean left-hand a-b ridge count and mean right hand atd angle compared to controls. These differences could be explored as a potential biomarker in diagnosing and early detection of schizophrenia in Ghanaians.

Comparative evaluation of dermatoglyphic patterns between skeletal class I and skeletal class III malocclusion.

Background: Dermatoglyphics is the study of various dermal configurations on the fingers, palms, and soles. These appear during the 12th week of intrauterine life and develop completely by the 24th week. It is said that they remain constant thereafter. The aim of the present study was to compare and assess the association of dermatoglyphic patterns between skeletal class I and skeletal class III malocclusion. Methods: Finger and palm prints were collected using the ink and roller method from 604 subjects who were divided into skeletal class I, class III with maxillary retrognathism and class III with mandibular prognathism based on lateral cephalogram assessment. Results: Loop pattern was more predominant in skeletal class I malocclusion subjects and whorl pattern was more frequent in the other two groups. Total finger ridge count and atd angle also showed significant difference between the study groups. Conclusions: The present study attempted in assessing the association between dermatoglyphic patterns and skeletal malocclusion. Analysing dermal configurations may aid in indicating the type of developing malocclusion and thus help in interceptive and preventive orthodontics.

Fingerprint patterns in neuropsychological disorder depression among south Indian population.

Depression is a pervasive mental health disorder characterized by persistent sadness and an inability to enjoy activities that were once enjoyable. This study compares the dermatoglyphic patterns of depressed patients with those of healthy, normal individuals in order to determine if dermatoglyphic patterns can be used as biomarkers for early diagnosis and prompt intervention of depression. A total of 100 depressive disorder patients of both sexes between the ages of 18 and 60 were selected for the study. Dermatoglyphic patterns of individual digits were analyzed using the "Ink and Paper" technique. The Whorl, Loop, and Arch patterns, as well as the AFRC, TFRC, and a-b ridge count, were examined using One-Way ANOVA significance and a Chi-Square test using SPSS 20.0. The results showed that the right hand in the depressive diseased group had decreased numbers of Whorls in the 2nd and 5th digits, and decreased numbers of Loops in all five digits. Similarly, decreased numbers of Whorls were found in the 1st, 2nd, 4th, and 5th digits of the left hand, as well as decreased Loops in the 4th digit. However, there were no changes in the Arches of either hand when compared to the control group. The AFRC and TFRC were significantly decreased (p<0.0001), but there was no significant decrease in the a-b ridge count in the depressive diseased group when compared to the control group. Dermatoglyphics, a noninvasive method, can serve as a screening indicator for depressive individuals, the appearance of the decreased count of whorls and loops parameters might be used as an exploratory sign.

DERMATOGLYPHIC FEATURES OF MEN’S FINGERS PRONE TO DRUG

The article presents data on the peculiarities of the dermatoglyphic constitution of the distal, middle and proximal phalanges of the fingers in men prone to drug crimes. The object of the study was the peculiarities of the dermatoglyphic parameters of the distal, middle and proximal phalanges of the fingers obtained from 60 men aged 18 to 59 who were convicted of drug crimes and 60 persons of the control group. During the study, it was found that radial loops (52.31%) and curls (29.23%) are most common on the fingers of the left hand, complex patterns (8.08%), arcs (6.92%) and ulnar loops are less common (3.46%), curls (44.23%) and radial loops (39.62%) and arcs (5.77%), ulnar loops (5.38%) and complex patterns are most common on the fingers of the right hand (5.00%), at the level of a statistical trend (p&lt;0.10), the pattern on the right and left hands differs according to the indicator of the total frequency of radial loops on the fingers of both hands - 52.31% versus 39.62% (φ = 1, 30; p &lt; 0.10) and curls W – 29.23% versus 44.23% (φ = 1.59; p &lt; 0.10). A comparative analysis of the total ridge counts for the fingers of the left and right hands of drug criminals and men of the control group showed that the variances of this variable in the groups are equal, and since the p-level of the Student's test for the values of these indicators is significantly less than 0.05, the average values of the total ridge counts numbers on the fingers of the right hand of drug offenders and men of CG differ at a high level of statistical significance.

Assessment of Palmar Patterns and Dermatoglyphics in Oral Cancer Patients of Bareilly City: An Observational Study

Background and objectives: Dermatoglyphics are the dermal ridge configuration on the digits, palms and soles. Dermatoglyphics may be used as an easily accessible tool in the study of genetically induced diseases as genetic or chromosomal defects may be expressed as alterations in dermal ridges. They are genetically determined and influenced by environmental forces that are operating before birth. Several studies have shown an association between dermatoglyphics and different types of cancer. Hence this study was undertaken to determine whether specific dermatoglyphic patterns exist that help in predicting the occurrence of oral squamous cell carcinoma.&#x0D; Aim: This study was conducted to study palmar and dermatoglyphic patterns in oral carcinomas patients in Bareilly city.&#x0D; Material and method: Our study was conducted among 59 subjects having oral cancer in Bareilly city. A modified case history proforma and comprehensive history was taken. Finger and palm prints were collected from Oral squamous cell carcinoma (OSCC) patients using the digital method and were evaluated qualitatively and quantitatively using an appropriate statistical test.&#x0D; Results: Finger and palm prints were evaluated qualitatively and quantitatively. Significant findings in patients with oral squamous cell carcinoma in both hands were: Increased frequency of Loops and whorls, Loop patterns are common in Thenar/I1 area, Increased Total finger ridge count on the right hand, increased ab count on the left hand, more atd angle on the left hand.&#x0D; Conclusion: Our study concluded that dermatoglyphic patterns may have a role in identifying individuals either with or at risk for developing oral squamous cell carcinoma. It can be used to identify high-risk group so that early primary and secondary preventive measures can be instituted to prevent the occurrence of these lesions.
