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.

Fingerprints as an Index for Cooperation in Children during Dental Treatment: A Cross-sectional Study

Abstract Background: The behaviour of a child is an essential factor in paediatric dentistry. Fingerprints are unique and constant over a lifetime. Some studies indicate a relationship between fingerprint type and behaviour mode of children during dental treatment. Therefore, fingerprint patterns might help to predict the extent of cooperation by children during dental procedures. Aim: The aim of the study was to investigate the possible relationship between fingerprint patterns and the cooperation of children during dental procedures. Materials and Methods: In this cross-sectional study, 80 children aged 4–7 years were examined. The children meeting the inclusion criteria in their first dental visit are scheduled for a dental procedure. During this procedure, based on Frankl’s scale, the child’s behaviour is assessed. Subjects were categorised as cooperative or uncooperative. A different examiner records the child’s fingerprint. The data were compared with SPSS Version 21. Intergroup comparison was made using the Chi-square test at a significance level of P < 0.05. Results: Amongst the 47 cooperative children, 34 children had loop fingerprint pattern, 7 had whorl fingerprint pattern and 6 had arch fingerprint patterns. Amongst the 33 uncooperative children, 14 had loop fingerprint pattern, 15 had whorl fingerprint pattern and 4 had arch fingerprint pattern. The difference was significant between the groups (P < 0.01) based on dermatoglyphic characteristics, with the loop pattern being seen in cooperative children and the whorl pattern in uncooperative children. Conclusion: There is a relationship between fingerprint type and behaviour mode of children, with loop pattern being the primary fingerprint type amongst the cooperative group and whorl pattern amongst the uncooperative group.

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.

Dermatoglyphic Phenotype of a Person As One of the Criteria For Its Identification

Introduction. One of the methods used to track the pattern of heredity and variability of human psychophenotypic traits is dermatoglyphic. It is used to study the hereditary patterns that form skin lines on the fingertips, palms, and soles of a person.
 The aim of the study to develop expert criteria for the informativeness of dermatoglyphic fingerprints in the system of forensic medical identification of a person.
 Materials and methods. The object of the study was fingerprint cards obtained from 460 people (200 women and 260 men) aged 18-59 years living in Ukraine. The dermatoglyphic method and the method of statistical analysis were used.
 Results. It has been established that dermatoglyphic features can be congenitally unchanged (pattern type and its orientation, comb and delta count, rudiments and dysplasias);
 congenital variables (altitude-latitude index, delta-interphalangeal fold distance, line density); acquired variables (white lines and scars).All these features have not only individual but also group variability.
 Conclusion. The proposed forensic classification of dermatoglyphic features does not include individual features of the structure of patterns (minutiae), the appearance of which is largely due to the action of random factors and therefore is valuable for forensic science (fingerprinting).

Дифференцирующие возможности папиллярных узоров средних фаланг пальцев рук (на примере евразийских популяций)

Introduction. An assessment of the currently known data on intergroup variability of papillary patterns of fingers' middle phalanges suggests the possibility of using these characteristics to differentiate Eurasian populations. Material and methods. The study conducted on the prints of fingers' middle phalanges of 1178 men from 12 ethno-territorial groups of Russia and Kyrgyzstan. These are mainly archival materials represented by impressions of the entire palmar surface of the hand. Therefore, we applied а classification that unites morphologically similar variants to eliminate possible errors in determining the types of skin patterns. Results. Statistically significant differences revealed when comparing the proportions of dermatoglyphic features in Caucasian populations, on the one hand, and mixed Caucasian-Mongoloid or Mongoloid populations, on the other. The occurrence frequencies of straight and hook patterns increase, and the frequencies of distal arc and complex double patterns decrease in the presence of a Mongoloid (or Uralic) component. The results of cluster analysis and multidimensional scaling confirmed the division of populations depending on the presence of a Mongoloid, including Ural, component in their racial composition. Within the main clusters, groups were differentiated according to anthropological similarity and territorial proximity. The skin patterns’ complex of digital middle phalanges is very sensitive to the presence of a Mongoloid (or Uralic) component in Caucasian populations, as well as the main dermatoglyphic features of the hand. The differentiation of samples according to the patterns of the middle phalanges largely corresponds to the division based on classical racial and key dermatoglyphic characteristics. However, as a result of multidimensional scaling, the Volga-Kama populations were located further from the Caucasoid than both Mongoloid samples. Therefore, shares’ distribution of united dermatoglyphic signs in Mongoloid populations requires clarification using additional data. Conclusion. The results of various statistical analyzes allow us to conclude that it is possible to use dermatoglyphic characteristics of digital middle phalanges to differentiate Caucasoid samples and groups with a Mongoloid (or Ural) component. The presence of the Mongoloid component in the groups is accompanied by a decrease in the complexity of the papillary patterns on the middle phalanges. @ 2023.

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.

Dermatoglyphs in People with Down Syndrome and People with Normal Karyotype: A Comparison of Quantitative Characteristics

Background: All types of chromosomal aberrations have an impact on the development of dermatoglyphs, which changes both their quantitative and qualitative characteristics. This study aims to compare the quantitative characteristics of dermatoglyphs between individuals with Down syndrome and those with normal karyotypes in the Kosova Albanian population. Methods and Results: The quantitative characteristics of digitopalmar dermatoglyphs were analyzed on 104 individuals (54 men and 50 women) with Down syndrome from Kosova's Albanian population. The dermatoglyphs of 403 Albanians from Kosova with normal karyotypes (the control group) were also analyzed quantitatively. Using the method devised by Cummins and Midlo, dermatoglyph traces were obtained and analyzed. We analyzed the quantitative features of both the dermatoglyphs of the fingers and the dermatoglyphs of the palms of the hands. Moorhead and Seabright's peripheral blood culture technique was utilized to analyze the karyotypes of individuals with Down syndrome. A total of 40 dermatoglyphic variables were analyzed. When the quantitative dermatoglyphic features of men with Down syndrome and the control group were compared, significant differences were discovered in 20 of the dermatoglyphic variables. Significant differences were discovered in 21 of the dermatoglyphic variables when the features of women with Down syndrome and the control group were compared. One of the most distinctive characteristics of Down syndrome was the breadth of the atd angle, which should be taken into consideration. Compared to the control group's males and females, the males and females with Down syndrome exhibit wider atdT angles (161.91° vs. 92.60° [P<0.0001] and 165.48° vs. 94.75° [P<0.0001], respectively). Conclusion: The size of atd angles is the factor that most closely identifies people with Down syndrome.

Finger print patterns distribution among diabetics and non-diabetics in western Uganda population

Background: Dactyloscopy is a branch of dermatoglyphics (the study of epidermal ridges) which involves assessment and classification of fingerprint patterns for identification. All fingerprint patterns are laid down permanently from the third month of the intra-uterine life and they remain unchanged throughout the life. This is also the time when all organs in the body are finalizing their development. Therefore, a positive association of the dermatoglyphic features with different diseases like diabetes, mongolism, schizophrenia and leprosy have been well documented in the literature. The aim of the present study was to evaluate the dermatoglyphic patterns and the specific variations which may be used as a valuable diagnostic tool for early detection of diabetes mellitus. Methods: This was a prospective cross-sectional study, a total of 150 diabetic subjects and 150 non- diabetics (control) were selected from the KIUTH Western Uganda and their fingerprints were taken by the Indian ink method. The print patterns including whorls, arches, ulnar and radial loops were analysed and the variations were cross-tabulated between sex, the side of the hand and pattern distribution indexes. Data was analysed using SPSS version 26 and Dankmeijer's index and Furuhata's index were used to assess variability of the fingerprint patterns. Chi square tests was used to test for significance in variations at a confidence interval of 95%. Results and conclusion: Ulnar loops were the most predominant patterns among diabetic subjects at 35.2% followed closely by whorls at 35.1%. The most common pattern were whorls found in both hands of females at 21% (315/1500), whilst the most common pattern for male group were whorls at 17.5% (262). However, some fingers such as the ring finger completely lacked an arch pattern in both groups. The increase in arches was strongly supported by a significant increase in Dankmeijer’s index. The presence of high number of ulnar loops can therefore maybe used as an early indicator of type two diabetes.

Assessment and Correlation between Dactyloscopy and Behavior of Children Undergoing Dental Treatment: A Cross-sectional Study.

To assess and correlate dactyloscopy and behavior of children undergoing dental treatment. A total of 30 children aged 4-8 years who needed at least one restoration without administration of local anesthesia were included. Two examiners recorded the behavior of the child as per Frankl's behavior rating scale and after the treatment, the subjects' fingerprints were taken using an ink pad and white paper. The data were analyzed using Statistical Package for the Social Sciences (SPSS) versions 23 and a Chi-squared test was carried out (p < 0.05). The loop type fingerprint had the highest frequency, while the archtype had the lowest. The child's behavior differed greatly (p < 0.05) based on dermatoglyphic characteristics, with the loop pattern being seen in cooperative children and the whorl pattern in uncooperative children. There is a positive correlation between fingerprint type and children's dental care. Dactyloscopy can be used to determine the behavior of children coming for dental treatment and hence help in their management. Janiani P, Subramanian EMG.

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.

Антропологическая изменчивость русского населения в европейской части России по данным дерматоглифики

The variability of frequencies of different types of palm and finger patterns in the Russian population has repeatedly become the subject of research by both anthropologists and criminologists. The purpose of this paper is to analyze the geographical variability of dermatoglyphic features in the Russian population of the European part of Russia, taking into account all published and available archival data. In total, materials of 36 dermatoglyphic series from more than 5 thousand people were analyzed. The research program included a set of 6 “key traits” (Dl10, Ic, t, Hy, DMT, Th/I), the effectiveness of which for differentiating the Eurasian population was convincingly shown in the papers of G. L. Heet, as well as additional features reflecting the patterning of the skin ridges on fingers and palms. It was found that the variability of dermatoglyphic traits in groups of Russians of the southern and especially northern regions is noticeably higher than in the central region. The magnitudes of some features (frequencies of some types of finger and palm patterns) correlate with the geographical location of the groups. The general picture of dermatoglyphic variability of the Russian population in the European part of Russia cannot be characterized as homogeneous, although it does not have a clear structure. The high variability of features in groups of the Russian North can only partly be due to genetic drift in conditions of lower population density and is explained by the inclusion of a substratum and heterogeneous population, speakers of various Finno-Ugric languages. Involvement in the analysis of 40 craniological series of the 17th – early 20th centuries allowed us to group all anthropological material into 15 territorial samples and to compare the data of two independent systems of anthropological traits. Integration of the data using the method of principal components revealed a consistent variation of the two systems of traits. The vector “southwest–northeast” corresponds to the direction of maximum anthropological differentiation of the groups. Despite the turbulent historical events of the 20th century, two world wars, active migration processes, the main direction of anthropological variability of the Russian population has not changed dramatically.

Peculiarities of the Crest Pattern of the Fingers in Persons Prone to Crimes Against Human Life

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.&#x0D; The aim To determine the complex of dermatoglyphic parameters of fingers that make up the dermatoglyphic constitution of persons who committed murder.&#x0D; 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.&#x0D; 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 &gt; 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 &lt; 0.01), complex patterns on the I, II and IV fingers of the left hand (φI = 1.86; φII = 1.69, p &lt; 0.05; φIV = 2.57, p &lt; 0.01), curls on the first finger of the right hand (φІ = 2.37, p &lt; 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 &lt; 0.001).&#x0D; Conclusions.

Evaluation of Dermatoglyphic Features of Type 2 Diabetic Patients as Compared to Non-Diabetics Attending Hospitals in Southern Ethiopia.

BackgroundDiabetes mellitus (DM) is a complex metabolic disorder characterized by persistent hyperglycemia resulting from defects in insulin secretion, insulin action, or both. Type 2 DM has a strong hereditary background. A study of the dermatoglyphic features can help in the early identification of people with a genetic predisposition to develop type 2 DM.Purpose of the StudyThe study was aimed to compare the finger and palmar dermatoglyphics features in type 2 diabetic and non-diabetic patients and to evaluate the association with other variables.Patients and MaterialsInstitution-based cross-sectional study was conducted in one referral hospital and three primary hospitals located in Gedeo Zone. Three hundred ninety study participants (130 type 2 diabetics and 260 non-diabetics) from adult OPD and diabetic clinics were included in the study. The association among different dermatoglyphics variables was analyzed using the chi-square test. An independent t-test was conducted to analyze the mean difference and to test the significance of numerical variables. A statistically significant association was declared at P-value <0.05.ResultsIn the present study, a total of 3900 digits (1300 from type 2 diabetic and 2600 non-diabetic) were analyzed for distribution of digital dermatoglyphic patterns. Loop pattern is found to be the commonest in both study groups with a prevalence of 65.8% and 60.7% among type 2 diabetics and non-diabetics, respectively. Both the right-left axial tri-radius angle was significantly higher in type 2 diabetes mellitus patients compared to non-diabetic study participants. Total finger ridge counts and absolute finger ridge counts showed no significant difference in both groups.ConclusionThe study revealed Loop pattern was more frequent in type 2 DM compared to non-diabetic study participants. Whorl type was more common than arch type in non-diabetic patients compared to type 2 DM groups. The result also showed tri-radius angle is significantly wider in diabetic groups in both hands.

Correlation of Dermatoglyphics with Clinical Characteristics of Cervix Carcinoma Patients at a Tertiary Care Centre in Kanpur, Uttar Pradesh, India

Introduction: Cervix cancer is most prevalent cancer in females. Early detection and regular screening methods are helpful for the prevention of cervix cancer related morbidity and mortality. Early stages of development, dermatoglyphic features are generated under genetic influences, but they can be influenced by environmental variables during the first three months of pregnancy. These trends may reflect an individual’s genetic make-up and, as a result, his or her proclivity for particular diseases. Therefore, the dermatoglyphic prints may serves as a non invasive anatomic marker of cervix cancer risk, allowing for early detection and treatment. Aim: To characterise dermatoglyphics in cervix cancer patient and correlate them to principal clinical features. Materials and Methods: This cross-sectional study included 300 cervix cancer patients, analysed the clinical presentations and dermatoglyphics prospectively after obtaining ethics approval from a tertiary care hospital, Kanpur, Uttar Pradesh, India, during December 2016-January 2020. The palmar dermatoglyphics (loops, arches, whorls and palmar angle) were obtained and evaluated for correlation with principal clinical features like vaginal discharge, postmenopausal bleeding, and intermenstrual bleeding using Spearman’s correlation test. Results: In this study, the frequencies of arches, loops and whorls were 81, 2051, 868 respectively. A strong positive correlation (r&gt;0.92) existed between whorls of palmar digits and clinical features of cervix cancer. Conclusion: Dermatoglyphic patterns could be used to investigate the genetic cause of cervix cancer and could potentially be used as a non invasive anatomical screening method in high-risk patients.

Dermatoglyphic characteristics of Chinese professional table tennis players

To perform dermatoglyphics analysis and to explore the possible relationships between dermatoglyphic characteristics and sports level of Chinese table tennis players. A total of 92 Chinese professional table tennis players were recruited and divided into ordinary group and excellent group according to their levels. Their dermatoglyphic patterns on the palms and fingers were collected and statistically analyzed. Our results showed that the data revealed significant differences (p < 0.05) between the ordinary group and the excellent group in terms of atd angle, thenar eminence, total number of a-b ridges and double loop whorl, while no significant differences (p > 0.05) were observed in concentric whorl, arch pattern and loop pattern. In conclusion, these findings may provide experimental evidence for the application of dermatoglyphic analysis as a tool for future selection of elite table tennis players.

Изучение изменчивости основных характеристик дерматоглифики на ногтевых фалангах пальцев у подростков

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&lt;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&lt;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.
