p> Background
Dermatoglyphics is frequently used in understanding the proximity with non-communicable diseases including diabetes mellitus. Diabetes mellitus is one of the most common non-communicable diseases all over the world. The present study is an attempt to understand the association of palmer dermatoglyphic traits [i.e. a-b ridge count (ABRC), c-d ridge count (CDRC), presence of multiple number of axial triradii (t, t' & t") in a single palm, td ridge count (TDRC), atd angle, btd angle and ctd angle] with type 2 diabetes mellitus (T2DM).
Material and methods
Subjects included 30 clinically diagnosed adult female T2DM patients and 60 healthy controls from the Bengalee Hindu Caste population of West Bengal, India. Bilateral palm prints were collected following standard ink and roller method.
Results
Present study revealed that T2DM patients have significantly (p<0.05) lower ABRC, CDRC and TDRC. On the other hand, significantly (p<0.05) higher presence of multiple number of axial triradii t, t' & t" was found in the palm of T2DM patients compared to the controls. T2DM patients also demonstrated significantly (p<0.05) higher values of atd and btd angle. However, T2DM patients demonstrated significantly (p<0.05) lower value of ctd angle than that of controls, only when both hand were considered.
Conclusion
The results the present study indicated that dermatoglyphic traits may be used for early identification of at risk individuals for surveillance with a view to prevent the disease onset.

This research was aimed at comparing the Digital Patterns of the Igbos' and Okirikas' in Southern Nigeria. The study was done between 2014 and 2015 in University of Port Harcourt. Non-experimental analytical study design; 200 subjects were used for the study. 100 subjects were Igbos and other 100 were Okrika with age between 18-60yrs, all of which were normal subjects. These subjects were randomly selected through simple random sampling method from Igbo and Okrika Population. Chi square test analysis was carried out using Statistical Package for the Social Sciences (SPSS 20.0 version). Igbos' had the following results: Arch 9.1%, Ulnar Loop 57.4%, Radial Loop 3.3%, Whorl 30.2% whereas Okrikas' had Arch 10.3%, Ulnar Loop 58.0%, Radial Loop 4.4%, Whorl 27.3%. The test differences in patterns for digits of Igbo and Okrika subjects according to the result shown indicated that there is no form of relationship between the two tribes under study (P>0.05). The study established a characteristic digital pattern for both tribes. The result of the study also suggests that both tribes are distinct and unique in their genetic makeup as such are unrelated by any means in their ancestry.

In the article, on the basis of peculiarities of indicators of finger and palmar dermatoglyphics, the analysis of reliable discriminatory models of the affiliation of practically healthy men to the southern or other administrative-territorial regions of Ukraine was constructed and conducted. In most cases, the combination of all dermatological variables has a low level of discrimination (the highest level is established between men of the southern and northern regions of Ukraine). Most often, discriminant variables between men of the southern and other regions of Ukraine are the type of pattern on the fingers of the right hand and the asymmetry of the comb account of the palm lines.
... Dermatoglyphics is the study of dermal ridge patterns of fingertips, palms, and soles of the feet which was first proposed by Cummins and Midlo in 1926. [1] These dermal ridge patterns are determined genetically, by the interaction of several genes, and thus, they are characteristic feature of a person which differs from one person to another. Galton in his studies classified different fingerprint patterns as loops, whorls, and arches. ...
Background: Dermatoglyphics is developing its importance in everyday life, and researchers are keen to unveil various unknown aspects of dermatoglyphics in biology, anthropology, genetics, and medicine. The present study was conducted to assess the relationship of thumbprint, learning methodologies, and academic performance of medical students. Methodology: Hundred and forty-three medical students were voluntarily participated in this study. Ethical committee clearance was obtained before the study. Validated questionnaires were distributed to the students and their right-hand thumbprints were collected simultaneously. The data were analyzed using Microsoft Excel. Results: The most common dermatoglyphic pattern observed among the students was whorls. Malays, Malaysian Indians, and Chinese mostly had whorl pattern, while among the Sri Lankans, the most common pattern was radial loop. A high percentage of students with ulnar loop scored distinction while students with other patterns mostly scored pass marks. Active learning strategies such as bringing reference books to class, revising previous chapters before class, taking notes in class, and surfing Internet for learning were seen mostly among the students with ulnar loop. Conclusion: Most of the students with whorl pattern were either in low or average scoring groups. Individuals with ulnar loop were significant for this study as they had higher scores and better learning methodologies compared to other students. © 2018 Journal of Datta Meghe Institute of Medical Sciences University.
... Dermatoglyphics was derived from the Greek word "dermis" meaning "skin" and the "glyph" meaning "curving". Dermatoglyphics is a term first coined by Cummings and Milado [1]. Dermatoglyphics is the scientific study of papillary ridges in the palm of the hand and soles of feet Purkinje. ...
... The hand comparison of ridge count is stated to be efficient in determining zygosity. [10] Dermal ridges are formed during the 3 rd or 4 th months of fetal life and are thus largely determined by heredity [22,23] and remain unchanged throughout life. The differences in the intrauterine environment of the MZ twin pair are responsible for the differences in ridge configurations in as much the same way that the prints of the right hand of Moderate degree of agreement was obtained between zygosity established by facial appearance and by hand comparison of total ridge count. ...
The study of twins provides a unique opportunity to evaluate the genetic and nongenetic contributions to a variance of multitude of traits. Twin research has revealed the impact of a strong genetic component to the variance of many dental traits. The present study was conducted to assess the dental caries and oral hygiene status in monozygotic (MZ) and dizygotic (DZ) twins. A random sample of 129 MZ and DZ twin pairs aged 6-15 years were included in this study. The zygosity of twin pairs was initially recorded by facial appearance and later determined by dermatoglyphics. Dental caries and oral hygiene status were recorded in these twin pairs and the data were subjected to statistical analysis. No significant difference was observed in the mean decayed, extracted due to caries and filled teeth (deft) in primary dentition and decayed, missing and filled (DMFT) in permanent dentition scores and oral hygiene status in MZ and DZ twin pairs. The similarity observed in oral health status reflects the effects of a shared environment in MZ and DZ twin pairs.

... Human fingers are known to display friction ridge skin that consists of a series of ridges and furrows, generally referred to as fingerprints. [1] Fingerprint friction ridge details are described in a hierarchical order (based on resolutions) ranging from level zero to three, in which the count will be possible only at level one. [2] The facial trait of an individual has to be defined as the soft tissues of the face together with the underlying bony skeleton. ...
The fingerprints and face recognition are two biometric processes that comprise methods for uniquely recognizing humans based on certain number of intrinsic physical or behavioral traits. The objectives of the study were to predict the facial height (FH), facial width, and ratios from thumbprints ridge count and its possible applications. This was a cross-sectional study. A total of 457 participants were recruited. A fingerprint live scanner was used to capture the plain thumbprint. The facial photograph was captured using a digital camera. Pearson's correlation analysis was used for the relationship between thumbprint ridge density and facial linear dimensions. Step-wise linear multiple regression analysis was used to predict facial distances from thumbprint ridge density. The result showed that in males the right ulnar ridge count correlates negatively with lower facial width (LFW), upper facial width/upper FH (UFW/UFH), lower FH/FH (LFH/FH), and positively with UFH and UFW/LFW. The right and left proximal ridge counts correlate with LFW and UFH, respectively. In males, the right ulnar ridge count predicts LFW, UFW/LFW, UFW/UFH, and LFH/FH. Special upper face height I, LFW, height of lower third of the face, UFW/LFW was predicted by right radial ridge counts. LFH, height of lower third of the face, and LFH/FH were predicted from left ulnar ridge count whereas left proximal ridge count predicted LFW. In females only, the special upper face height I was predicted by right ulnar ridge count. In conclusion, thumbprint ridge counts can be used to predict FH, width, ratios among Hausa population. The possible application of fingerprints in facial characterization for used in human biology, paleodemography, and forensic science was demonstrated.
... The same procedure was repeated for recording palm prints by firmly pressing palm by applying board pressure on A4 paper which was stabilized on smooth sponge [11]. Finger and palm prints obtained were inspected by the magnifying glass for assessing the predominant pattern such as whorl, loop and arch [12] for both Group 1 (malocclusion) and Group 2 (dental caries). ...
Objective: To identify specific predominant rugoscopy and dactyloscopy patterns in children associated with malocclusion and dental caries for the predilection of malocclusion and dental caries. Material and Methods: 800 children between 8-16 years were screened and among them, 150 were who met inclusion criteria were selected and divided into 2 Groups. Based on Angle’s malocclusion, Group 1 (n = 90) was subdivided into Group 1A (30 - Class I), 1B (30 - Class II) and 1C (30 - Class III). Based on DMFT, Group 2 (n = 60) were subdivided as Group 2A (30 - Caries free) and 2B (30 - Caries active). Both Groups had an equal distribution of boys and girls. Finger and palm prints were analyzed using Cummins and Midlo; rugae patterns were analyzed using Thomas and Kotze classification. The obtained data were subjected to statistical analysis using Chi-square test. Results: Based on dermatoglyphics, predominant loop pattern was observed in all the subgroups of Group 1 (1A, 1B and 1C). Based on rugae pattern, predominant wavy pattern in Group 1A and curved pattern in both 1B and 1C were observed. In Group 2, loop dermatoglyphic pattern and wavy rugae pattern were predominant in Groups 2A and 2B. Atd angle was highest in Groups 1A (41.60) and 2B (42.36). Gender distribution showed curved pattern of palatal rugae in Group 2B (Caries active) females. Statistical significance was seen in dactyloscopy and rugoscopy patterns among both Group I and Group II (p<0.05). Conclusion: The curved rugae pattern in Group 1B and 1C can be considered as a predictor in Class II and Class III malocclusions. Gender differentiation showed predominant curved pattern in females of Group 2B (Caries active). © 2017, Association of Support to Oral Health Research (APESB). All rights reserved.
... Indeed, the digital dermatoglyphics distribution in our Algerian populations reveal the dominance of UL followed W, A and finally RL patterns.

The study of Dermatoglyphics has a great importance in medical, judicial, criminal and anthropological research. Human dermatoglyphic traits present variations within and between populations. The purpose of this paper is to provide a descriptive analysis of digital dermatoglyphic traits in three Algerian populations and enrich the anthropogenetic database of this population. The current study was conducted on 315 healthy and consenting individuals, 228 (144 males and 84 females) from Oran, the second most important city in Algeria located in the northwest of the country, 46 Reguibates (20 males and 26 females), and 42 Zenata (16 males and 26 females). The results show that the most common descending order of pattern type frequencies for both hands in the three samples is Ulnar loop, Whorl, Arch, Radial loop. One exception is seen in the Reguibates sample that has an unusually high frequency of radial loop. The analysis of qualitative digital characters revealed bimanual differences in the three populations.
... Dermatoglyphics has proven to be a useful and cheap genetic marker in identifying genetic syndromes and disease (Jatti et al., 2014). Dermatoglyphics is a term applied to the study of fingers patterns, palms patterns and soles patterns along with their quantitative measures (Cummins and Midlo, 1961). The word " dermatoglyphics " comes from two ancient Greek words: " derma " means skin and " glyph " means carving (Bhat et al., 2014;Karthick et al., 2015). ...
Gastrointestinal cancers are malignant diseases with high mortality rate. Early diagnosis of patients could improve the results of treatment. Many studies used dermatoglyphics as a biomarker to predict the incidence of genetic diseases and cancers. This study assessed the association between gastrointestinal cancers and particular fingerprint patterns, which could be useful in early diagnosis of these malignancies. The study was conducted on 153 histopathologically confirmed gastrointestinal cancer patients and 299 healthy individuals. The fingerprints were taken by a specific method of rolling the subject's fingers or thumbs in ink. The data were analyzed for the significance using the chi-square test and the t-test. Odds ratio with 95% confidence intervals were calculated. Dermatoglyphic analysis showed that whorl and loop patterns significantly changed in the case group as compared to control. However, the odds ratio suggested that whorl pattern in 6 or more fingers might be a risk factor for developing 2 S. Abbasi and M. Rasouli Genetics and Molecular Research 16 (3): gmr16039762 gastrointestinal cancers. Our results showed that there is an association between fingerprint patterns and gastrointestinal cancers, and so, the dermatoglyphic analysis may aid in the early diagnosis of these cancers.

In the article, the analysis of discriminatory models of the affiliation of practically healthy men to the northern or other administrative-territorial regions of Ukraine on the basis of peculiarities of finger and palmar dermatologic indices was constructed and analyzed. The highest level of discrimination was found among the men of the northern and southern and northern and eastern regions of Ukraine. Most often discriminant variables between men of the northern and other regions of Ukraine are the type of pattern on the fingers of the right hand and the asymmetry of the comb account of the lines a-b and c-d. The largest contribution to discrimination between northern and other administrative-territorial regions of Ukraine has the asymmetry of the comb account of the lines a-b and c-d.
Some of the qualitative and quantitative palmar dermatoglyphic characters of 100 Ralli caste individuals and 100 Manne Dora tribals of Andhra Pradesh are reported in this paper. The variables studies, are principal mainline formulae, frequency of tine patterns in different configurational areas, interdigital ridge counts on a-b, b-c and c-d and angle atd, the bimanual and bisexual differences among these two populations are ascertained.
This present paper records the distribution of C line termination among the Ahom of Dibrugarh district, Assam. The C line terminates frequently on ulnar side and no significant bisexual differences are observed. Only females show significant bilateral difference.
Finger dermatoglyphics have been analyzed in 167 Banai (77 male and 90 females) a small endogamous population with Mongoloid affinities of south Garo Hills district of Meghalaya. Analysis of the data reveals that the average Banai (both male and female) possess more loops than whorls.
Qualitative digital dermatoglyphics is studied in a sample of 200 individuals (100 males and 100 females) belonging to Muttarasi, a backward community of Chittoor district, Andhra Pradesh. The order of pattern occurrence is L > W > A in both the sexes. The frequency of whorls is slightly more among females (42.7%) than males (41.2%) The frequency of ulnar loops in males (53.8%) is more than females (51.1%). The frequency of arches found to be high among females (5%) than males (3.7%). Both bilateral and bisexu al difference s are statistically insignificant. The values of all papillary indices in females are fou nd to be more than in males. The percentage of total symmetry is slightly more in males (69.2%) than females (66.4%). The total frequency of monomorphic hands is also more in males (48.0%) than females (37.0%).
C-line polymorphism has been reported among four endogamous sub-castes of Reddis namely Desuri Reddis (DSR), Pedakanti Reddis (PKR), Motai Reddis (PKR), and Kodide Reddis (KDR) in Rayalaseema region of Andhra Pradesh. All four study groups show higher frequency of radial termination on right hands (57% to 52%) and ulnar terminations on left hands (54.50% to 30.50%). The proximal types are more on left (31.50% to 11.50%) than right (19.50% to 6%) hands. The absence of C-line is more than twice in left than right hands. Comparison has been made with some caste populations of Andhra Pradesh. The comparative picture shows that backward and schedule caste populations come closer to Reddis. While, other tribal populations fall apart.
The present study examines the heretability of finger and palmar quantitative dermatoglyphic traits bycalculating Karl Pearson’s coefficient of correlationship ‘r’ and regression equation between the actual parents andchildren and unrelated pairings. The sample is made up of 50 couples and their 135 children (66 sons and 69 daughters)belonging to the Khurkhul community of Manipur. The traits included in the study are: total finger ridge count,absolute finger ridge count, pattern intensity index, palmar main line index, atd-angle and palmar a-b, b-c, c-d ridgecounts. Highly significant correlation values higher than the theoretical value of 0.5 of parent-child were observed inthe studied quantitative feature, except palmar b-c and c-d ridge counts. The estimated values of correlation coefficient‘r’ found in parent (x)-child (y) correlationship for total finger ridge count (TFRC), absolute finger ridge count(AFRC) and finger pattern intensity index (PII) agree with the theoretical value of coefficient of correlation betweenmid-parent and the child i.e. 1/√2 or 0.71. In all the studied quantitative dermatoglyphic features, randomly pairedunrelated ones show very low correlation values when compared with those of the related parents and children’scorrelation values, except father-child correlation value of palmar b-c ridge count. Higher correlation coefficientvalues of ‘r’ were observed in finger than in palmar. This indicates that environmental factors exert greater effect onthe palmar region in early prenatal life than do on the finger.
Palmar flexion creases in the Mann tribe of West Garo Hills district of Meghalaya. North East India were studied in a sample of bilateral palm prints of 123 male and 116 female subjects It was found that there exists no bimanual or bisexual variation with regard to this trait in the present population. The Mail a tribe was found to differ significantly from most of the otter populations of North East India in respect of palmar floion creases.
Finger and Palm print data on a total of 343 Main from 10 villages of Visakhapatnam district, Andhra Pradesh are presented. Palmar quantitative characters exhibited inter group difference between the two Mali sub-groups — the Bodo Mali and Sung Mali suggesting the operation of micro-evolutionary forces, especially keeping in view the small population size of the Bodo Mali. This corroborates the work of Malhotra et al. (1974, 1981) on the Nandiwalla.
The frequency of digital patterns and their indices, mean values and t’values of finger ridge count and interdigital ridge counts, frequency of patterns in hypothenar, thenar and interdigital areas, frequency of various types of axial triradii of 70 primary amenorrhea cases and 30 controls are presented. It is observed that there is a slight increase of loop ulnar and arches in the study group compared to the control group. In the ridge count also the study group exhibited less mean values than control group. Furthermore, thereis evidence for the association of accessory axial triradii and elevated axial triradii in the primary amenorrhea cases likely to have chromosomal abnormalities.
The Primary (idiopathic) generalized epilepsy shows a unique finger-ball patterns. Among the male epileptic patients loop was predominant, whereas among the female epileptic patients whorl was predominant as compared to their respective control groups.However, in total epileptic patients (male+Female) Whorl was predominant as compared to the total normal control (Male+Female). 37 pedigrees showed the disorder in a single or couple of relatives other than the patients, Besides it, both the x² -tests and the l-tests exhibited heterogeneity between the epileptic patients and the normal control.This heterogeneity may be attributed to the possible cause of epilepsy.

The note describes the results of finger and palmar dermatoglyphics of the Lyngam tribe of Meghalaya, India.
Finger and palmar dermatoglyphic patterns have been analyzed in 100 Deori (50 Males, 50 females) individuals living in the Dibrugarh district of Assam. India.
The Gond of Sagar District. Madhya Pradesh were studied for planer creases in relation to ana-tomical axis The results show that distribution of plantar creases is well marled in SMBC as compared with DMBC and TMBC, excepting the fibular incidence of DMC in both the soles among females.
The axial triradius is usually present in the proximal part of the film in alignment to the fourth metacarpal bone. Sometimes there may be two or three and rarely none. Accordingly starting from the proximal pan of the palm, they are referenced to as proximal (l). intermediate (O and distal to and when absent (O). However these terms are qualitative and lack precision. The present paper pro-poses the logical method for the quantitative evaluation of the positions of the axial triradii.
The present study is based on 33 post-axial type of polydactylous hands to examine association between extra digit and corresponding digital triradius. The results show that acute Polydactyly occurs in association with an extra digital triradius on palm but in syndactylous Polydactyly extra digital is not found at the base of duplicated digit.
Qualitative and quantitative aspects of finger ball patterns of three endogamous populations of Muslim from Visakhapatnam. Andhra Pradesh are studied. Loops are more frequent among the three population, followed by whorls and arches. The whorl/loop ratio has more variation in the three groups. Males of the three groups exhibited higher mean counts of URC. Shia and Sunni exhibits significant differences for ridge counts Sunni and Dawoodi Bohra do not differ significan.ly. The three populations are compared with local Non-Muslim and Muslims from other parts of India.
A sample of 230 Yanndis (115 males and 115 females) from Yerpedu Mandal. Chittoor District of Andhra Pradesh were studied for qualitative and quantitative finger dermatoglyphic characters Among qualitative and quantitative characters. bisexual differences have been observed, but statistically these are non-significant.
Finger and palm print data on 285 Nooka Doras form eleven villages of Ananthagiri Mandal of Visakhapamam District. Andhra Pradesh are presented. Palm rather than finger revealed greater variation There is a positive correlation between the digital ridge count and ridge count estimated from triradial point to the basal crease of the digit.
Bilateral ridge count asymmetry and correlations among three palmar configurational areas. viz a-b-c and c-d in Manne Dora tribe from Andhra Pradesh are investigated. The highest mean directional asymmetry (MDA) for ridge count is noticed in c-d among men and a-b among women. The interdigital area c-d registers the highest mean absolute asymmetry (MAA). The correlation coefficients between ridge counts of various configrational areas indicate that correlations between homologous areas indicate that correlations between homologous areas are stronger than between non-homologous areas. Also significant bisexual difference is found for ridge count correlations between palmar areas in right hands and between non-homologous regions.
In a sample of 800 unrelated male individuals, 200 from each sub-castes of Desuri Reddis (DSR), Pedakanti Reddis (PKR), Motati Reddis (MTR) and Kodide Reddis (KDR) were studied to estimate variation and distance among and between the populations by using qualitative finger dermatoglyphic characters such as finger pattern types, symmetrical and assymetrical distributions and monomorphic hands. The highest (2.402054) and lowest (1.384128) B1 values are observed between the DSR-MTR and PKR-MTR groups, respectively. The cluster analysis dendogram and principal coordinate analysis depict clearly the heterogenous nature of the selected Reddi groups.
The relationship between pattern intensity index with total finger ridge count and absolute finger ridge counts has been investigated in Wancho, a Mongoloid population of Tirap district, Arunachal Pradesh, India. The results show a stronger linear relationship between pattern intensity index and the absolute finger ridge count than with total finger ridge count.
Исследование гендерных различий пальцевой дерматоглифики у лыжников-гонщиков Тюменской области показало, что наибольшая частота встречаемости завитков у девушек-лыжниц выявлена на I и II пальцах ладоней; у юношей – на IV; наименьшая – у девушек-лыжниц – на V пальце обеих рук, у юношей – на V пальце левой, III пальце правой ладони. Определены пальцевые формулы завитков.
