Association of Reproductive Parameters with Dermatoglyphics in Breast Cancer Patients, Healthy and High-Risk Individuals

Background Breast cancer has a wide array of risk factors, and its confounding reproductive aetiologies have been paramount in defining the predictive ability of the disease. Similarly, a strong link between qualitative dermatoglyphic patterns and predisposition to breast cancer has been well documented through genetic linkage. Therefore, this study aimed to discern the affiliation between the aforementioned risk factors of breast cancer. Methods The study was carried out in 3 groups of 90 age-matched individuals of - breast cancer patients, high-risk individuals and healthy individuals. A detailed reproductive history was taken including factors such as age at menarche, menstrual regularity, age at menopause (if attained), breastfeeding, obstetric parameters and age at first live birth. Qualitative dermatoglyphics were procured through the standardised ink and paper method to get a remarkable rolled fingerprint. The variations in gynaecological and obstetric parameters and qualitative dermatoglyphic patterns were studied and their significance was computed using the chi-square test on InStat software where p values < 0.05 were considered significant with a 95% confidence interval. Results Highly significant values (p<0.0001) were found in all gynaecological and obstetric parameters where a higher frequency of whorls in breast cancer patients, arches in high-risk individuals and an equivalent frequency of arches and whorls were predisposed to healthy individuals. Limitations Although this study might have identified certain predominating patterns with higher frequency, the consistency might vary from place to place due to differing dermatoglyphics according to ethnicity. A small number of patients receiving chemotherapy experienced - chemotherapy-induced adermatoglyphia - where the loss of fingerprints or very faint fingerprints was difficult to perceive. These patients were not included in the study to ensure maximum efficacy in interpreting the dermatoglyphics. Conclusion Previous attempts failed to link dermatoglyphic indices and reproductive parameters, this study found a significant correlation between the variables in the three distinct groups. Most breast cancer patients are diagnosed late with a majority presenting to doctors in advanced stages where survival rates are marginal, so by this method, we can get a simple, practical, non-invasive and easily affordable screening technique for the above risk factors. This technique could also be employed for non-symptomatic women who might have a positive family history of breast cancer as a part of risk assessment for early diagnosis and treatment. Therefore, paving way for further research into the prognostic abilities of gynaecological parameters through qualitative dermatoglyphic indices.

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.
 Aim: This study was conducted to study palmar and dermatoglyphic patterns in oral carcinomas patients in Bareilly city.
 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.
 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.
 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.

Mean Atd Angle among Type 2 Diabetes Mellitus Patients Visiting a Tertiary Care Centre: A Descriptive Cross-sectional Study.

An atd angle is one of the dermatoglyphic patterns which is an indication of the degree of distal displacement of the axial triradius on the palm. This is one of the markers of diabetes mellitus that is used as a screening tool in order to reduce the risk of onset and initiate early treatment. The aim of this study is to find the mean atd angle among type 2 diabetes mellitus patients visiting a tertiary care centre. This descriptive cross-sectional study was done among diabetic patients in a tertiary centre from 9 June 2021 to 5 May 2022. Ethical approval was taken from Institutional Review Committee (Reference number: KUSMS/IRC 40/2021). Both palm prints of study subjects were taken and the atd angle was measured. Convenience sampling was done. Point estimate and 95% confidence interval were calculated. Among 133 palm prints of diabetic patients, the mean atd angle was 42.13±4.73° (male: 41.90±4.75° and female: 42.35±4.70°). The right palms showed mean atd angle of 42.31±4.42° and that of left palms was 41.94±5.04°. The mean atd angle among type 2 diabetes mellitus patients is similar to other studies done in similar settings. dermatoglyphic; diabetes mellitus; prevalence.

Sexual dimorphism and bilateral difference of fingerprint sweat pore among Slovak population

Third level dermatoglyphic markers show a high level of individuality. Despite this fact, the occurrence of individual sweat pore types is still insufficiently studied due to their problematic extraction. The aim of our study was to evaluate the variability of sweat pore types on distal fingertips in the Slovak population and to establish the most uniform method for delineating the evaluated fingerprint area of 1 cm2 in size to avoid bias in the obtained data. In this study, the variability of seven sweat pore types (round, rhomboid, elliptical, square, rectangular, triangular, hexagonal) on distal phalanges were investigated in a sample of 60 volunteers (30 females and 30 males) from the Slovak population. The evaluated area was 1 cm2. Since none of the previously used definition methods seems to be completely reliable, we developed our own method using individual types of dermatoglyphic patterns. This method allowed an uniform location of the studied fingerprint area. The results suggest that sweat pores, like other dermatoglyphic characteristics, have strong identification potential. Several statistically significant bilateral and intersexual differences were found in both male and female populations. Significant intersexual differences in all categories were found in rhomboid and rectangular sweat pore types. Their use could be applied to partial or otherwise unusable fingerprints. The results of this study could help to incorporate these prints into the identification process, allowing their full use.

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.

Sex differences in radioulnar contrasts of the finger ridge counts across 21 human population samples

Aim: The aim of the present study was to demonstrate the existence of uniform sexual dimorphism in some radioulnar contrasts between different finger ridge counts within the same hand in a large set of populations, thus confirming the universal nature of this dimorphism in humans.Subjects and methods: We analysed individual finger ridge counts (10 values on each hand) of both hands from archival sources (mainly the Brehme-Jantz database). In total, these included 4412 adults from 21 population samples covering all permanently inhabited continents and encompassing very different and geographically distant human populations. We calculated the contrasts (differences) of all pairs of ridge counts (45 per hand) and used diverse methods to assess the direction and degree of dimorphism of them across all population samples.Results: The highest sexual dimorphism was observed for nine contrasts involving the ridge count of the dermatoglyphic pattern on the radial side of the second finger of the right hand (R2r). Among these contrasts, we then found four that had the same direction of dimorphism in all 21 populations. The most dimorphic was the contrast R1rR2r – the difference between the ridge count of the radial side of the thumb and the radial side of the index finger.Discussion: Thus, these dermatoglyphic traits can be further investigated as potential markers of prenatal sex differentiation from ca. 10th week of intrauterine development. However, it will be useful to address the detailed factors and mechanisms for differences in the degree of dimorphism of these traits in different populations.

Qualitative Analysis of the Right Plantar Dermatoglyphic Configurations in Himachal Pradesh: A Dimorphic Study

Introduction: Dermatoglyphics is defined as the study of the configurations on the plantar aspect of the feet and the palmar aspect of the hands. It is a well established fact that these epidermal configurations are distinct for each and every individual. Aim: To study and analyse the plantar dermatoglyphic patterns on the right sole of the individuals of Himachal Pradesh and to know its implication in gender determination. Material and Methods: This cross-sectional study was conducted in the Department of Anatomy, Adesh Institute of Medical Sciences, Bathinda, Punjab, India, and the data was collected over a period of one year (May 2021 to May 2022). The sole dermatoglyphic prints of 400 individuals (200 males and 200 females) of the age group 18-45 years without any known medical conditions were analysed for the dermatoglyphic patterns visualised in the Hallucal/Thenar/ First Interdigital Area (Rt Th/H/ID1), Second Interdigital Area (Rt ID2), Third Interdigital Area (Rt ID3), Fouth Interdigital Area (Rt ID4), Hypothenar Distal Area (Rt HTD), Hypothenar Proximal Area (Rt HTP) and the Calcar Area (Rt C) of the right sole. The findings thus obtained were then subjected to Chi-square test using the Statistical Package for the Social Sciences (SPSS) version 21.0 software. Results: The mean age of the subjects included in the study was 29±4 years and 16±7 years for 200 Himachali males and 200 Himachali females, respectively. The study showed that there was indeed an association between the right plantar dermatoglyphic patterns and the sex of the people belonging to Himachal Pradesh, India. The results suggest that the distribution of the dermatoglyphic patterns on Rt Th/H/ID1 of the females was significantly different from the males (p-value <0.05). On the Rt ID2, Rt ID3 and Rt ID4, the differences observed between the females and males were highly significant (p-value <0.001) whereas on the Rt HTD, Rt HTP and the Rt C, all the males and females depicted a lack of pattern. Conclusion: The results of this investigation suggest that there exist some significant differences between the male and female subjects of Himachali population. The plantar dermatoglyphic patterns could therefore be utilised as an important tool to determine the gender of an individual in forensic and medico-legal aspects as well as to determine the relationship of an individual to an ethnic group based in different geographical areas.

Study of Fingerprint Patterns in Relation to Gender and ABO Blood Groups

Fingerprints are considered as the best tool of identification of a person. Fingerprint evidence is by far the mosteffective and reliable evidence in the court of law. The reason being fingerprint pattern persist same throughoutthe life and no two individual has similar pattern. Both blood group and dermatoglyphic pattern have geneticinheritance so an attempt has been made to analyze their correlation with gender and blood group of an individual.The objective of the study was to determine correlation (if any) between the fingerprint pattern, blood group andgender. The study was conducted on 150 students (88 males and 62 females) in the age group of 18-25 years.The fingerprint pattern of the study participants was compared with the gender and ABO-Rh blood group aftertaking their Informed written consent. Amongst ABO blood group, the most common blood group was O (40%),followed by B (35.33%), A (19.33%) and AB (5.34%). Rh + ve was the most common rhesus factor (97.33%). The loopwas the most common pattern (69.14%), followed by whorl (26.06%) and arch (4.80%). Frequency of loops werehighest in both the Rh-positive and Rh- negative subjects of ABO blood groups except O -ve blood group wherewhorls dominate. Loops are maximum seen in blood group B while whorls are more common in blood groupO and arches with blood group A. The present study confirms that loop is the most common type of fingerprintpattern while arch was the least common. The study revealed significant association between the Fingerprintpattern, Gender and ABO blood group.

Dermatoglyphic analysis of asthma sufferers in a population of students at the faculty of mathematics and science, Universitas Negeri Padang

Asthma is a disease defined as chronic inflammation of the airways which is characterized by recurrent coughing and shortness of breath. Dermatoglyphs are the appearance of tendrils and tendril patterns on the fingers, palms, toes and soles. Dermatoglyph is used as an aid in the detection of a number of diseases that have a strong heritable basis and is also used to detect abnormalities. This study aims to analyze and compare the patterns of dermatoglyphics in asthma sufferers and non-asthmatics on the fingertips. This type of research is descriptive research with cross sectional sampling method. Samples were taken from the student population of the Faculty of Mathematics and Natural Sciences, Padang State University as many as 100 samples of fingerprint patterns. The results obtained showed that there was a significant difference in the number of arch fingerprint patterns of asthmatics compared to normal individuals. Seeing this significant difference in numbers indicates a possible link between fingerprint patterns and asthma phenotypes.

A Study to Assess Dermatoglyphic Characterization and Salivary Ph in Early Childhood Caries

Dental caries detection at an early stage by applying dermatoglyphics and assessing the salivary pH levels can facilitate the initiation of preventive measures at a younger age. However, there are little data available to substantiate the utility of dermatoglyphics and salivary pH in studying the genetic basis of dental caries.Therefore,the present study was aimed to assess the correlation between dermatoglyphic patterns and salivary pH in children with and without Early Childhood Caries (ECC).This cross-sectional study was carried out in 156 children of randomly selected schools in Puducherry in the age group of 3-5 years. Children with decayed, extracted and filled (defs) score of = 5 for group 1 (children with ECC) and defs score of 0 for group 2 (children without ECC) were considered for the study. Their fingerprint patterns and salivary pH were recorded and analysed using Chi-square test and Spearman correlation tests.In children without ECC group, loop frequency 10 and 7 was the most observed category whereas in subjects with ECC group, whorl frequency 7 and 8 was the most observed category. Significant proportion of whorls was seen more in both males and females in ECC group(p<0.0001). The mean salivary pH of subjects with ECC was 6.35±0.38 which was statistically significant (p<0.0001). Dermatoglyphic pattern and salivary pH can be used as predictive tool for diagnosis of ECC as there exists a definite variation in dermatoglyphic patterns and salivary pH in children with ECC and caries-free group. There are various methods to diagnose ECC but so far, there is no method to predict ECC using a dermatoglyphic pattern, salivary pH and ECC that may further facilitate initiation of preventive measures to avoid the progression of ECC at a younger age.

Comparison of scanner method and stamp pad method for dermatoglyphic patterns

Dermatoglyphics are useful in anthropological, medico legal and genetic studies. Hereditary and prenatal environmental factors leading to malocclusion may also influence fingerprint patterns which are classified into arches, loops and whorls. Dermatoglyphic pattern can be recorded by stamp ink pad method or scanner method. This study was conducted with an aim to compare stamp pad method and scanner method in terms of visibility and ease of identification by panel of postgraduate students of orthodontic speciality.Finger print pattern of 140 digit of 14 participants with aged range of 20-40 years, were recorded by both stamp pad method and scanning method using Futronic scanner. Print out of scanned images was taken. Post graduate students were briefed about identification of different types of dermatoglyphic pattern and asked to identify finger prints of each subject which were arranged randomly in a file. The fingerprint pattern was cross-checked and identified by the operator. A questionnaire in the Google form was also given to each participant to know the ease of identification and visibility of finger pattern in both patterns. 92.8% of fingerprint pattern were correctly judged by participants for scanner method whereas 90% of fingerprint pattern were correctly judged by same participants for stamp pad method in comparison to judgement made by operator. According to participants scanner method was easier to identify due to better visibility.77.8% participants found smudges in ink pad, 83.3% participants found better color contrast in scanning method. 72.2% participants found stamp pad method to be more time consuming.It can be concluded that the scanner method may be better in terms of identification, visibility as seen by the response of participants. Therefore, there was less error in identification of fingerprint pattern with scanner method but with experience, accurate results could be derived from both the techniques.

Evaluation of the relationship between dermatoglyphics and mandibular third molar impaction: A cross-sectional study.

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.

EVALUATION OF DERMATOGLYPHIC PATTERNS AND THEIR CORRELATION WITH SKELETAL MALOCCLUSIONS

Background and Objectives: Dermatoglyphics deals with the study of the epidermal ridges and their congurations on the ngers, palms and soles. Epidermal ridge patterns form early in fetal development and remain unchanged throughout life and play a signicant role in the diagnosis of many disorders with genetic background. As the primary palate, lip and dermal ridges develop during the same period of intrauterine life, the genetic message contained in the genome - normal or abnormal, is deciphered during this period and is also reected by dermatoglyphics. The present study was undertaken to evaluate the different dermatoglyphic patterns and their correlation with skeletal malocclusions. The study was conducted on 90 individuals divided into 3 equal groups- skeletal Methods: class I, II and III. Dermatoglyphic patterns were recorded using ink method following rolling impression technique. The dermatoglyphic data was assessed for different nger ridge patterns and total ridge count (TRC). On compar Results: ison skeletal class I group showed markedly decreased number of loops and increased total ridge count (TRC). Skeletal class II showed markedly increased number of loops and markedly decreased TRC. Skeletal class III showed markedly decreased number of arches and increased TRC. Loops were found to be the most predominant pattern in skeletal class II and III groups. The mean TRC was found to be increased in skeletal class III group and markedly decreased in skeletal class II group which was statistically signicant. Dermatoglyphics can be used as a screening tool and for early prediction of skeletal mal Conclusion: occlusion at a younger age group. Dermatoglyphics have important practical and clinical implications which can be applied for preventive and interceptive orthodontics among paediatric patients and also for parent counseling.
