Perinatal brachial plexus palsy (PBPP) is a handicap quite commonly encountered in daily routine. Although birth trauma is considered to be the major cause of the defect, it has been observed that PBPP occurs only in some infants born under identical or nearly identical conditions. The aim of this study was to test the hypothesis of genetic predisposition for PBPP. It is well known that digito-palmar dermatoglyphs can be used to determine hereditary roots of some diseases. Thus, we found it meaningful to do a study analysis of digito-palmar dermatoglyphs in this disease as well, conducting it on 140 subjects (70 males and 70 females) diagnosed with PBPP. The control group was composed of fingerprints obtained from 400 adult and phenotypically healthy subjects (200 males and 200 females) from the Zagreb area. The results of multivariate and univariate analysis of variance have shown statistically significant differences between the groups observed. In spite of lower percentage of accurately classified female subjects by discriminant analysis, the results of quantitative analysis of digito-palmar dermatoglyphs appeared to suggest a genetic predisposition for the occurrence of PBPP.

Both handedness and dermatoglyphic asymmetry reflect early, prenatal influences and both have been reported to be associated with male sexual orientation; handedness has been related to female sexual orientation as well. Neurohormonal and developmental perturbation are two competing hypothesis that attempt to explain these connections. We attempted to replicate these associations and to extend dermatoglyphic asymmetry findings to women. Dermatoglyphic directional asymmetry and fluctuating asymmetry were unrelated to sexual orientation. Homosexual women, but not homosexual men, had highly significant increases in non-right-handedness compared with same-sex heterosexual controls. Although this pattern of results does not allow resolution of the two competing models, it does lend additional support to a biological basis of sexual orientation.

: This article describes a study conducted to determine the basic dermatoglyphic traits, located in relation to gender in persons of Uzbek population. Provides definitions of the differences in rate of dermatoglyphic depending on nationality.
Conclusion: Dermatoglyphic analysis can be used as an indicator of malocclusion at an early age, thereby aiding the development of treatments aiming to establish favorable occlusion. Inheritance and twin studies, as well as those conducted in different ethnic groups, are required to examine these relationships further.
Dermatoglyphics is the study of epidermal ridge patterns on the palm, fingers, sole and toes. They are genetically determined and are useful in diagnosis of various genetic diseases like Diabetes mellitus. There are three types of fingerprint patterns: Arches, loops and whorls. Finger prints of both hands are not same and ...

Dermatoglyphics, ridge constellations on the hands and feet, are permanently formed by the second trimester of pregnancy. Consequently, they are considered "fossilized" evidence of a specific prenatal period. A high frequency of dermatoglyphic anomalies, or a high rate of dermatoglyphic asymmetry
Full Text Available The features of forming of dermatoglyphics of feet are compared for sportsmen and people, which do not go in for sports. In researches took part 209 men and 198 women in age 17-19 years, which did not go in for systematic sports. The quantitative and high-quality indexes of dermatoglyphics of fingers and soles of foot were determined on a method T.D. Gladkova. It is certain that as genetic markers of propensity to the sporting gift there can be more difficult dermatoglyphics patterns (W on the first finger and soles of feet and more considerable indexes of comb-shaped count on the first tiptoes. A dermatoglyphics of fingers and hands of hands is more informing in a prognosis high motive gift, than dermatoglyphics of feet. It can be predefined that is analysed greater amount of indexes of dermatoglyphics of hands as compared to feet. Probability of genetic prognosis is more high for girls, what for boys.
Full Text Available Introduction: Because dermatoglyphic features are strongly affected by genetic and environmental factors, using it as supportive evidence in the diagnosis of hereditary disorders becomes a reality. Offspring of patients suffering from chronic periodontitis have a high prevalence rate of periodontal breakdown, suggesting strong familial influence. Aims: The present study intends to evaluate and compare the dermatoglyphic patterns in controls and periodontally compromised patients. Settings and Design: A hospital based cross-sectional study was conducted, including a total of 60 individuals, divided into study and control groups of 30 each. The study group included clinically diagnosed periodontitis patients.Materials and Methods: The digital prints were collected using biometric scanner and palmer prints using digital flatbed scanner. Care was taken to ensure that full prints of ridges were obtained. The periodontal status of all 60 participants was assessed clinically for attachment level and pocket depth. Later, Russell's periodontal index was also calculated. Statistical Analysis: The data obtained was subjected to statistical analysis using chi square and Student's t-test. Results: Among the finger ridge patterns, whorl pattern was found to be the most common in the study group whereas loop pattern was the most common in the control group. Mean total finger ridge count in the study group (165.69 ± 25.30 was significantly higher (P = 0.001 than the control group (125.4 ± 16.38. Mean dat angle was significantly higher (P = 0.039 in the study group (60.60 ± 2.76 than the control group (59.20 ± 2.62. Conclusion: Dermatoglyphics may serve as an early predictor in identifying high risk group individuals of developing diseases like periodontitis.

Autism is a neurodevelopmental disorder originating from early childhood; nevertheless, its diagnosis is in older ages. In addition to heredity, environmental factors are also of great significance in the etiology of the disease. Dermatoglyphic patterns, albeit varied, remain stable for a lifetime and yield a large number of patterns upon examination. Studies have shown a significant association between dermatoglyphics and some diseases, especially genetic ones. We compared fingerprints between patients with autism and normal individuals in a Fars population living in Khorasan-Razavi Province, Iran, in 2015. The right and left hand fingerprints of 104 autistic individuals (case group; age range=5-15 y) were collected using a fingerprint scanner. The same process was performed for 102 healthy individuals, in the age range of 6 to 25 years. All dermatoglyphic patterns and ridge counts were determined. The data were analyzed using the Mann-Whitney nonparametric test and binomial distribution. There was a significant difference in the distribution of the dermatoglyphic patterns on the right and left thumbs and the index fingers between the case and control groups (Pbiometric parameters in the screening of children with autism.

Recent studies on the etiopathogenesis of multiple sclerosis (MS) all point out that there is a polygenetical predisposition for this illness. The so called "MS Trait" determines the reactivity of the immunological system upon ecological factors. The development of the glyphological science and the study of the characteristics of the digito-palmar dermatoglyphic complex (for which it was established that they are polygenetically determined characteristics) all enable a better insight into the genetic development during early embriogenesis. The aim of this study was to estimate certain differences in the dermatoglyphics of digito-palmar complexes between the group with multiple sclerosis and the comparable, phenotypically healthy groups of both sexes. This study is based on the analysis of 18 quantitative characteristics of the digito-palmar complex in 125 patients with multiple sclerosis (41 males and 84 females) in comparison to a group of 400 phenotypically healthy patients (200 males and 200 females). The conducted analysis pointed towards a statistically significant decrease of the number of digital and palmar ridges, as well as with lower values of atd angles in a group of MS patients of both sexes. The main discriminators were the characteristic palmar dermatoglyphics with the possibility that the discriminate analysis classifies over 80% of the examinees which exceeds the statistical significance. The results of this study suggest a possible discrimination of patients with MS and the phenotypically health population through the analysis of the dermatoglyphic status, and therefore the possibility that multiple sclerosis is genetically predisposed disease.
Full Text Available Background: Oral squamous cell carcinoma (SCC is one name that causes panic and holds an undeserved high ranking as a killer. Another important condition which has become a major public health issue in South East Asia is oral submucous fibrosis (OSF. Not all the people using tobacco suffer from these diseases. Genetic predisposition might explain such an individual variability that can be predicted by using various cytogenetic markers. However, these studies are far more costly and complicated. So, dermatoglyphics may be of immense clinical significance to segregate those individuals who are at an increased risk for developing these diseases. Aim: The present study was conducted to analyze the palmar dermatoglyphics in SCC and OSF and find a "dermatoglyphic marker", if any. Study Design: Cross sectional study. Materials and Methods: 120 individuals were divided into four groups based upon their habits of tobacco/areca nut usage and presence of OSF/SCC. Dermatoglyphic patterns were recorded using standard ink method. Various patterns were analysed statistically in the four groups. Results and Conclusion: In SCC, there was an increase in frequency of arch and ulnar loop patterns on fingertips, decrease in frequency of simple whorl patterns on fingertips, decrease in frequency of palmar accessory triradii on right and left hands. Significant findings in OSF included an increase in frequency of arch and ulnar loop pattern, decrease in frequency of simple whorl patterns on fingertips, decrease in atd angle on right hand, decrease in frequency of palmar accessory triradii on right hand. The results revealed that the field of dermatoglyphics holds promising results for determining the genetic susceptibility of individuals to develop SCC and OSF.

Tel Hashomer camptodactyly syndrome is a rare disease and only a few cases have been reported. Dermatoglyphics potentially provide relevant phenotypic biomarkers that were initially noted as a vital clinical feature of this disease. Dermatoglyphics possibly can indicate growth disturbances that took place during early fetal development at the time when epidermal ridges were being formed into discernable patterns. Consequently, these intrauterine effects might well have occurred in association with the expression of the Tel Hashomer camptodactyly syndrome. Therefore, this review was undertaken to provide, as far as we know, the first attempt to broadly assess dermatoglyphic features that are connected with the Tel Hashomer camptodactyly syndrome. If a developmental association between dermatoglyphics and Tel Hashomer camptodactyly can be firmly established, this would probably document that Tel Hashomer camptodactyly disease has its origins during the early fetal period. A systematic literature search was conducted using articles from PubMed (Medline), POPLINE, Trip Database, Cochrane Library, and gray literature up to 31 March 2015. The review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Fourteen relevant publications were included in the review. There were 23 cases of patients with Tel Hashomer camptodactyly syndrome that were described in these published articles. We reviewed the dermatoglyphics of 21 available cases out of all of the published and electronically available cases of Tel Hashomer camptodactyly. Eight cases reported whorls to be the most common digital pattern with an expected rise of ridge count. Two cases show significantly high frequencies of arch patterns. Further, there were increased numbers of palmar creases, along with abnormal flexion creases or other palmar dermatoglyphic abnormalities reported in all cases. This review highlighted the desirability of thoroughly observing and

Full Text Available Context: Dermatoglyphic is the permanent imprint found in hands. Variations of dermatoglyphic patterns among the individuals have been noted. Aims: To find out the dermatoglyphic pattern variations in dental caries between study group and the control group. Settings and Design: A cross-sectional study was done on 300 Bengalee children of Kolkata between the age group of 4-14 years. Materials and Methods: The samples were divided into two groups; study group and control group. Dental caries were detected clinically using mouth mirror and probe in daylight. Ink was applied on palm and finger by pressure pad. Bilateral palm and finger prints were taken by placing the palm and fingers over glazed paper and applying pressure over palm. Finger and palm prints obtained were inspected by magnifying glass for the study of different dermatoglyphic parameters. Statistical analysis used: Analytical statistical method with the help of student′s t-test was used to determine mean values and gender differences in the findings using SPSS version 11.0. Results: The characteristic feature which shows significant increase in caries sample group were increased total finger ridge count (TRFC and absolute finger ridge count (AFRC on fingers, representing pattern size and types. ab count and tr count were significantly lower in male and female caries sample group compared with the control group. Conclusions: There was a significant difference between caries and control group in different patterns and number of "tri radii on fingers" in fingers, the percentage of patterns on all palmar areas, total number of triradii on palm and main line index. Perhaps more systematic larger samples consisting of different genetic population are necessary to verify the conclusion.
Full Text Available Background: Dental caries is the predominant cause of tooth loss in children and young adults. Mutans streptococci are the principal etiological agents of dental caries, of which Streptococcus mutans (SM and Streptococcus sobrinus are most important in terms of human caries. Genetic factors also contribute to dental caries of which dermatoglyphics is one. Aim: The aim of the study was to explore the unique relationship between genetic component (dermatoglyphics and dental components (dental caries, salivary pH, SM level and to identify children at particular risk of dental decay. Settings and Design: One hundred children, 6–12 years of age, were selected and divided into two groups: Group 1 (children with dental caries, subject group and Group 2 (children without dental caries, control group. Methods: Dermatoglyphic patterns were recorded using a digital scanner (CanoScan LiDE, and dental caries status was recorded with “decayed-extracted-filled teeth” index for primary teeth and “decayed-missing-filled teeth” index for permanent teeth. Salivary pH was determined using pH meter strips. SM level was estimated by microbial culture of collected saliva samples. Statistical Analysis: Mann–Whitney test, Wilcoxon test, and Z-test were applied. Results and Conclusion: (1 Subject group had a decreased frequency of loops, whereas control group had increased frequency of loop pattern on palmer digits (P < 0.001. (2 Subject group had a low salivary pH toward normal and control group had high salivary pH values toward normal (P < 0.001. (3 Subject group had high SM level as compared to control group (P < 0.001. Therefore, there exists a relationship between genetic component (dermatoglyphics and dental component (dental caries, salivary pH, and SM level.

The patients had a significantly higher count of loops on their right and left thumbs and their index fingers. A significant decrease in ridge counts for the right and left thumbs and the index fingers was observed in the patients compared to the controls. The results suggested that the patterns were associated with the risk of autism. The patterns may be drawn upon as biometric parameters in the screening of children with autism.

Recreational drugs have a significant impact on the lives of drug users, their close families andfriends, as well as their society. Social, psychological, biological, and genetic factors could make a personmore prone to using recreational drugs. Finger and A-B ridges (dermatoglyphics) are formed during the firstand second trimesters of fetal development, under the influence of environmental and genetic factors. Theaim of our study was to investigate and evaluate a possible link between dermatoglyphics and opium usage. The pattern of dermatoglyphics - finger and A-B prints - obtained from a group of opium users(121 patients) was compared to those obtained from a group of opium non-users (121 patients) from Birjand,Iran. The results were analyzed using chi-square, t and Mann-Whitney tests. The results showed that although A-B ridges of palms and fingers in our study group were highercompared to the control group, there was no significant difference between these groups. The only significantdifference was the fingerprint patterns of the left ring finger in the study group, which lacked the arch patternand had less loop patterns. The dominant type of fingerprint in the left ring finger was the whorl. In ouropium user group, the arch and loop fingerprint patterns were heterogeneous and significantly different incomparison with the control group (P < 0.01). These findings suggest that a genetic factor may increase the predisposition to recreational drugusage. Further research is required to confirm this possible impact of genetic factors on the addiction process.

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

Cerebral palsy is one of the main causes of severe disability in children. Sixty children (30 boys and 30 girls) were included in the study. Quantitative digito-palmar dermatoglyphic traits were analyzed. Prints of digito-palmar dermatoglyphs obtained from the children's parents (60 mothers and 60 fathers) and from 400 phenotypically healthy adults from the Zagreb ware used as control groups. Analysis of quantitative dermatoglyphic traits of the digito-palmar complex revealed statistically significant differences in a number of variables between the fathers and their children suffering from cerebral palsy (TRC 180.3 > 158.6), with a greater number of variables involved in male children with cerebral palsy. Some variables showed statistically significant differences in dermatoglyphic patterns between fathers and control group of healthy males as well as between boys with cerebral palsy and healthy control males. Differences in dermatoglyphic patterns were significantly lower between mothers and girls with cerebral palsy (TRC 152.1 mothers and healthy control females. Study results support the hypothesis on the possible role of genetic predisposition in the occurrence of central nervous system lesion, with a more pronounced paternal impact.
Full Text Available Abstract Background Breast cancer is one of the most extensively studied cancers and its genetic basis is well established. Dermatoglyphic traits are formed under genetic control early in development but may be affected by environmental factors during first trimester of pregnancy. They however do not change significantly thereafter, thus maintaining stability not greatly affected by age. These patterns may represent the genetic make up of an individual and therefore his/her predisposition to certain diseases. Patterns of dermatoglyphics have been studied in various congenital disorders like Down's syndrome and Kleinfelter syndrome. The prints can thus represent a non-invasive anatomical marker of breast cancer risk and thus facilitate early detection and treatment. Methods The study was conducted on 60 histo-pathologically confirmed breast cancer patients and their digital dermatoglyphic patterns were studied to assess their association with the type and onset of breast cancer. Simultaneously 60 age-matched controls were also selected that had no self or familial history of a diagnosed breast cancer and the observations were recorded. The differences of qualitative (dermatoglyphic patterns data were tested for their significance using the chi-square test, and for quantitative (ridge counts and pattern intensity index data using the t- test. Results It was observed that six or more whorls in the finger print pattern were statistically significant among the cancer patients as compared to controls. It was also seen that whorls in the right ring finger and right little finger were found increased among the cases as compared to controls. The differences between mean pattern intensity index of cases and controls were found to be statistically significant. Conclusion The dermatoglyphic patterns may be utilized effectively to study the genetic basis of breast cancer and may also serve as a screening tool in the high-risk population. In a developing

Hereditary ectodermal dysplasia is a genetic recessive trait characterized by hypohydrosis, hypotrichosis, and hypodontia. The affected individual show characteristic physiognomy like protruded forehead, depressed nasal bridge, periorbital wrinkling, protruded lips, etc. There is marked decrease in sweat and salivary secretion. Due to skin involvement palm and sole ridge patterns are disrupted. In this study an attempt has been made to classify the affected members according to the degree of penetrance by pedigree analysis and also study karyotyping for cytogenetics, dermatoglyphic analysis for the various ridge patterns and variations in the number of sweat glands by sweat pore analysis in affected individuals. A total of five families who were affected with ectodermal dysplasia were considered. Pedigree analysis was drawn up to three generation by obtaining history. Dermatoglyphics and sweat pore analysis was done by obtaining palm and finger print impression using stamp pad ink. Karyotyping was done by collecting 3-5 ml peripheral blood. Karyotyping was prepared using lymphocyte culture. Chromosomes were examined at 20 spreads selected randomly under ×100 magnification. Results were analyzed by calculating mean values and percentage was obtained. Karyotyping did not show any abnormalities, dermatoglyphic analysis and sweat pore counts showed marked variations when compared with normal. Moreover, pedigree analysis confirmed the status of the disease as that of the recessive trait. Large number of affected patients needs to be evaluated for dermatoglypic analysis. Genetic aspect of the disease needs to be looked into the molecular level in an attempt to locate the gene locus responsible for ectodermal dysplasia and its manifestation.

Dermatoglyphic patterns, which are regularly used in judicial and legal investigations, can be valuable in the diagnosis of many diseases associated with genetic disorders. Dental caries although of infectious origin, may have a genetic predisposition. Hence, we evaluated the correlation between dental caries and dermatoglyphic patterns among subjects with and without dental caries and evaluated its association with environmental factors such as salivary pH. Totally, 76 female students within the age group of 18-23 years were clinically examined, and their decayed, missing, filled teeth (DMFT) score and oral hygiene index-simplified were recorded. Based on their DMFT score, they were divided into following three groups; group I (n = 16, DMFT score = 0), group II (n = 30, DMFT score salivary pH were recorded and analyzed using descriptive statistics. Dermatoglyphic pattern distribution in caries-free group showed more ulnar loops than high caries group (group III) while high caries group showed more whorl patterns. Presence of whorl with double loop, whorl within a loop was associated with high DMFT score. The total finger ridge count was lower in caries group. The mean salivary pH was higher in caries-free group than high caries group. Thus, we conclude that dermatoglyphic patterns may be potential diagnostic tool for detecting patients prone to develop dental caries.

To determine if Chinese individuals with non syndromic cleft lip with or without cleft palate (CL/P) display more dermatoglyphic asymmetry than unaffected relatives or controls. Case-control study with two control groups (genetically related and unrelated). A total of 500 CL/P probands from Shanghai, China, 421 unaffected relatives, and 66 controls of Chinese heritage. Finger and palm prints were collected, and pattern frequencies, total ridge counts (TRC), and atd angles were calculated. Asymmetry scores between right and left hands were defined for each of the three dermatoglyphic measures. Probands' asymmetry scores were compared statistically with the scores of unaffected relatives and controls. In general, the probands' asymmetry scores for TRC and atd angle did not differ significantly from the scores of either unaffected relatives or controls. However, probands with a positive family history of clefting showed significantly more asymmetry in their pattern types than either probands without a family history, unaffected relatives or controls. These results suggest that a unique genetic mechanism of developmental instability may obtain in CL/P individuals with a positive family history of clefting.

The objective of the present study was the development of the point-digital model for the scaless interpretation of the dermatoglyphic papillary patterns on human fingers that would allow to comprehensively describe, in digital terms, the main characteristics of the traits and perform the quantitative assessment of the frequency of their inheritance. A specially developed computer program, D.glyphic. 7-14 was used to mark the dermatoglyphic patterns on the fingerprints obtained from 30 familial triplets (father + mother + child).The values of all the studied traits for kinship diagnostics were found by calculating the ratios of the sums of differences between the traits in the parent-parent pairs to those in the respective parent-child pairs. The algorithms for the point marking of the traits and reading out the digital information about them have been developed. The traditional dermatoglyphic patterns were selected and the novel ones applied for the use in the framework of the point-digital model for the interpretation of the for diagnostics of consanguineous relationship. The present experimental study has demonstrated the high level of inheritance of the selected traits and the possibility to develop the algorithms and computation techniques for the calculation of consanguineous relationship coefficients based on these traits.
Full Text Available The congential anomalies involving Mullerian duct dysgenesis, the MRKH (Mayer-Rokitansky-Kuster-Hauser syndrome overlaps a ′community of syndromes′ which share, apart from a complete absence of uterus and vagina, associated presentations that include developmental abnormalities of skeletal, renal, dental and other dysmorphias. First described more than 400 years ago, this complement of anomalies now rechristened, the MRKH syndrome has been extensively studied. Found to occur once in every 4000 females; estimated on its incidence vary from 1/5000 to 1/20,000. Despite its fairly wide prevalence, this syndrome has remained largely underdiagnosed or cryptic. Social and cultural perceptions have perforce driven, the wide existence of the very personal handicap underground and unacceptable. Accidentally discovered during routine examination, during secondarily associated medical problems, the mullerian agenecies syndrome has been subject of a wide range of clinical and laboratory investigations. The oddity in the syndrome is that the patient appears absolutely normal and that it presents with no genetic marker. We herein report the palmar dermatoglyphic and doctylographic features of a patient with MRKH syndrome. However interpretation, show conclusively, at least in this single case that the MRKH syndrome can be diagnosed through its characteristic dermatography patterns. In our view, routine dermatographic study of all live females births may lead to not only an early but also a cost effective diagnostic method.

Full Text Available Background: In present study, we tried to determine significant palmar dermatoglyphic parameters in case of essential hypertensive’s in age group between 20-50 years and whether the parameters can be used for screening purpose i.e., early detection of hypertension. Method: With the use of modified Purvis Smith method, Black duplicating ink (Kores, Bombay was smeared on both hands one by one and prints will be taken by rolling the hands from wrist creases to finger tips on the roller covered with bond paper. While crystal bond paper, applied firmly over a wooden pad, was used for recording the inked epidermal ridge patterns. Rolled finger prints were recorded after applying uniform pressure on white bond paper from ulnar to radial side. Complete palm impression, including the hollow or the palm was obtained over paper. Thus one set of finger prints and palm prints was obtained. The prints obtained were immediately examined with hand-lens. Result: Right hand and left hand of the both male and female study group showed more number of arches than controls. Right hand and left hand of the both male and female study group showed more number of Radial loops than controls. The right hand and left hand of both male and female control group showed more number of ulnar loops than study group. The right hand and left hand of the male control group showed more number of Whorls than study, while in females, the right hand study group showed more number of whorls than control group and the left hand study group showed less number of Whorls as compared to control group. Conclusion: The present study indicates that there are some genetic factors which are involved in the causation of essential hypertension and it is possible to certain extent to predict from dermatoglyphics individual’s chance of acquiring essential hypertension. Like clinical history, examination and investigations, the dermatoglyphics will play an important role revealing the genetic

The patterns of the ridges of the skin of the fingers and palms were determined in sixty men with complex regional pain syndrome (type I) as a measure of disease prevention. The study included 25 dermatoglyphic traits: number of epidermal ridges on all ten fingers; their sum for five and ten fingers; four traits on both palms, i.e. between a-b, b-c and c-d triradii; atd angles: and their bilateral sum. The data obtained were compared with those recorded in a control group of 200 pairs of imprints of phenotipycally healthy male adults from the Zagreb area. Statistically significant difference from control values were found in 12 dermatoglyphic variables, including an increased sum of ridges on nine fingers (except for left second finger pad), and total sum for five and ten fingers. These findings suggested the polygenic system responsible for development of dermatoglyphics to be identical with some polygenic loci for the onset of algodystrophy syndrome, which might prove useful in disease prevention (e.g., taking fingerprints following a trauma and before rehabilitation), and to facilitate identification of risk groups, and thus the treatment for this longterm and yet obscure syndrome.

The objective of this study was to correlate dermatoglyphics and cheiloscopy with genetic inheritance in cleft lip and cleft palate patients. This was a case-control study to look for asymmetry in finger and lip print patterns. All of the participants were divided into two equal groups (40 mothers and 40 fathers in each group). The data were analyzed by three evaluators who were blind to the study to avoid any chances of error. A sample of 160 sporadic participants were identified and evaluated. Group A was composed of 80 healthy parents not affected by cleft lip and cleft palate but had at least one child born with nonsyndromic cleft. Group B consisted of 80 healthy parents not affected by cleft lip and cleft palate and had healthy children without cleft lip and cleft palate. Main outcome measures were marked dermatoglyphic asymmetry and specific lip print pattern in the study group. We found marked asymmetry in various fingerprints and specific type II and type III lip print in the study group when compared with the control group. It was observed that groove count on the lip was significantly more frequent in study group parents. Our study determined that there is a significant correlation between increased dermatoglyphic asymmetry and specific type II and type III lip print pattern in parents of children born with cleft. This could act as an important screening marker for the prediction of cleft lip and cleft palate inheritance.

Full Text Available Dermatoglyphic traits have been used to evaluate population structure and microdifferentiation in several populations. For Chibcha-speaking groups of Lower Central America there are few dermatoglyphic studies, but extensive linguistic, anthropological and genetic data support their historical, cultural and biological relationships. The main objectives of this study were to describe new dermatoglyphic data for six Chibcha- speaking Amerindians of Costa Rica, and to assess the relationships between these and other Amerindian and Eskimo groups, at different levels of population differentiation by means of multivariate analyses of quantitative traits. Sexual (2 =227.22, df=33, pLos dermatoglifos se han utilizado para evaluar la estructura poblacional y microdiferenciación de varias poblaciones. Para los grupos chibcha de Baja Centroamérica hay pocos estudios sobre dermatoglifos pero los datos lingüísticos, antropológicos y genéticos muestran la existencia de relaciones históricas, culturales y biológicas. Los objetivos del presente estudio fueron describir nuevos datos de dermatoglifos para seis tribus amerindias chibcha de Costa Rica y evaluar las relaciones entre estas y otros grupos amerindios y esquimales, a diferentes niveles de diferenciación poblacional por medio de análisis multivariados. Se encontraron diferencias significativas entre ambos sexos (2=27.22, df=3, p<0.01 y ambas manos (2=54.45, df=3, p<0.01, similar a lo descrito para otras poblaciones. Las tribus estudiadas se caracterizan por presentar alta frecuencia de arcos, baja frecuencia de verticilos y bajo conteo total de líneas. Al nivel más bajo de diferenciación poblacional, se compararon dos subpoblaciones cabécar (Atlántico y Chirripo y no se encontraron diferencias significativas (F=0.001, p=0.72 lo cual sugiere que los dermatoglifos no permiten discriminar entre grupos a este nivel.

Full Text Available Context: Widespread interest in epidermal ridges developed only in the last several decades; however, it is still at infancy in the world of dentistry. The word “dermatoglyphics” comes from two Greek words (derma: Skin and glyphe: Carve and refers to the epidermal skin ridge formations which appear on the fingers, palms of the hands, and soles of the feet. Aims: This study aims to assess the relationship between finger prints and chronic periodontitis. Materials and Methods: Two hundred patients were equally divided into chronic periodontitis and periodontally healthy group. The fingerprint patterns of the participants were recorded with a rolling impression technique using duplicating ink on executive bond paper. Statistical Analysis Used: The descriptive analysis of the data was presented as percentage frequency. The percentage frequencies of each pattern on each individual finger were calculated, and statistical tests were applied. Unpaired t-test was used for intergroup comparisons (P < 0.05. Results: There were statistically more whorls and less arches in both right and left hands in patients with chronic periodontitis. Conclusions: Dermatoglyphics can lead to early diagnosis, treatment, and better prevention of many genetic disorders of the oral cavity and other diseases whose etiology may be influenced directly or indirectly by genetic inheritance.

Forensic dentistry plays a vital role in detection and resolution of crime, civil proceedings and personal identification. With ever-increasing demands placed upon law enforcement to provide sufficient physical evidence linking a perpetrator to a crime, it makes sense to utilize any type of physical characteristic to identify a suspect of an offense. The least invasive and cost-effective procedure among all methods of human identification is the study of lip prints and fingerprints. This study is done to determine the predominant pattern of fingerprint and lip print in males and females and to correlate it for gender identification. The study sample comprised 100 individuals (50 males and 50 females) aged between 20 and 50 years; dark-colored lipstick was applied uniformly on the lips. The glued portion of cellophane tape was dabbed first in the center and then pressed uniformly over the corner of lips. Cellophane tape was then stuck to a white chart sheet for the purpose of permanent record. Lip print patterns were analyzed following the classification of Suzuki and Tsuchihashi. The imprint of left thumb was taken on a white chart sheet using a blue ink stamp pad and visualized using magnifying lens. Fingerprints were analyzed by following the classification given by Kücken. Correlation of lip print and fingerprint was analyzed using Chi-square test. The overall correlation of lip prints with fingerprints in males revealed branched lip pattern associated with whorl fingerprint and in females as vertical lip print pattern associated with loop fingerprint. We conclude that the study between lip print and fingerprint can aid in gender determination.

Full Text Available Anthropometry is a science of human body measurement that could be used for manufacturing artificial limbs or prosthesis, investigating body differences between populations, utilizing in forensics and criminology, or even in the diagnosis of some diseases. Two of the most important anthropometric characteristics are dermatoglyphic patterns and finger length. Many studies have evaluated the relation between these two characteristics in different diseases such as cancers. It assumed that dermatoglyphic patterns and finger length could be used as predictors of some cancers such as gastric, ovarian, prostate, testicular, and breast cancers. In this review, we evaluated the relation between dermatoglyphic variability and finger length in different cancers more precisely.

Since the original description of cerebral gigantism, about 85 cases have been reported. Four papers comment on familial occurrence but never in parents and their children. This paper describes the syndrome in a mother and her child, which, together with facts pointing towards prenatal etiology, such as excessive birthweight, striking mutual resemblance and abnormal dermatoglyphics, points to a genetic defect. Previous endocrine studies are enlarged by the findings of normal serum somatomedin and serum prolactin.

The comparative analysis of characteristics of three different cattle breeds (Brown Carpathian, Pinzgauer, Red Polish) on the 5 molecular-genetic markers and 5 muzzle dermatoglyphic types was carried out. It was indicated, that one characteristic can not be use as a breed-specific one but only their complex. The main aspect of search of this complex is the use of characteristics which mark different structure-functional systems of whole organism.

Full Text Available Kabuki syndrome is a rare congenital anomaly, characterized by five fundamental features, the "Pentad of Niikawa": dysmorphic facies, skeletal anomalies, dermatoglyphic abnormalities, mild to moderate mental retardation and postnatal growth deficiency. Patients present characteristic external ocular features, nonetheless they may also present significant ocular abnormalities. We report a case of a brazilian child diagnosed with Kabuki syndrome, addressing the clinical features observed, with emphasis on the ocular manifestations. This case highlights the existence of this syndrome and all of its complexity. The identification of preventable causes of loss of vision underlines the value of detailed ophthalmologic examination of Kabuki syndrome patients.
Full Text Available Aim: the current study examines features and correlations of particular psychodynamic, dermatoglyphic characteristics and body constitution of men with paranoid schizophrenia. Study groups: 25 men having the "paranoid schizophrenia" (F20.0, 27 men having no mental diseases. Methods: psychodiagnostic tests (Hand test, the Big Five Inventory (BFI, anthropometry; dactyloscopy. Results: there were statistically significant differences in such personality factors as: extroversion and openness among two groups. Significantly smaller sizes of the chest and thigh circumferences were found in men with paranoid schizophrenia. The schizophrenic group exhibited higher frequency of "ulnar loop" and "double loop" finger pattern occurrence. Our study found a number of somato-psychic, dermato-psychic and dermato-somatic correlations, as well as correlations between personality factors and age. Conclusion: the examination of personality features correlated with markers of dermatoglyphic and body constitution helped to identify the predictors of risks for developing paranoid schizophrenia. This makes it possible the identification of at-risk groups with their monitoring and focusing on preventive programs

Successful development of latent fingerprints can be helpful in solving the case but in case where fingerprints are smudged, distorted or overlapped, the question arises whether it is still possible to identify the person apart from dermatoglyphic features. Sweat residue present in the latent prints is supposed to have quite good quantity of cellular material which if analyzed properly can be used to generate forensic DNA profile of the individual and may answer the queries related to the effect of reagents used to develop the prints, as they may have a significant effect on the process of examination of this evidentiary material. In the present work an effort has been made to summarize the published review of literature on this aspect of personal identification.

Using cyanoacrylate or 'superglue' fuming to develop latent dermatoglyphic prints significantly altered the volatile and semivolatile compounds within the material of polyethylene zip-lock bags. Comparisons of SPME-GC/MS analyses of poly bags obtained before and after application of a glue fuming fingermark-developing technique resulted in markedly different material profiles of the bags. Not only were species added to the chemical composition of a bag, but other compounds that had been initially present were removed. These effects are particularly important for nuclear forensic investigations in the realm of route (pathway) analyses, and may also be of general interest to criminalistics laboratories that examine illicit drugs and their packaging.

Full Text Available The authors review environmental and neurodevelopmental risk factors for schizophrenic disorders, with emphasis on minor physical anomalies, particularly craniofacial anomalies and dermatoglyphic variations. The high prevalence of these anomalies among schizophrenic subjects supports the neurodevelopmental theory of the etiology of schizophrenia, since they suggest either genetically or epigenetically controlled faulty embryonic development of structures of ectodermal origin like brain and skin. This may disturb neurodevelopment that in turn may cause these subjects to be at increased risk for the development of schizophrenia and related disorders. The precise confirmation of this theory, at least in some cases, will provide further understanding of these illnesses, allowing easy and inexpensive identification of subjects at risk and providing guidelines for the development of new pharmacological interventions for early treatment and even for primary prevention of the illness.

Fingerprint has a strong oriented and periodic structure composed of dark lines of raised skin (ridges) and clear lines of lowered skin (furrows)that twist to form a distinct pattern. Although the manner in which the ridges flow is distinctive, other characteristics of the fingerprint called m inutiae a re what are most unique to the individual. These features are particular patterns consisting of terminations or bifurcations of the ridges. To assert if two fingerprints are from the same finger or not, experts detect those minutiae. AFIS (Automated Fingerprint Identification Systems) extract and compare these features for determining a match. The classic methods of fingerprints recognition are not suitable for direct implementation in form of computer algorithms. The creation of a finger's model was however the necessity of development of new, better algorithms of analysis. This paper presents a new numerical methods of fingerprints' simulation based on mathematical model of arrangement of dermatoglyphics and creation of minutiae. This paper describes also the design and implementation of an automated fingerprint identification systems which operates in two stages: minutiae extraction and minutiae matching

Full Text Available Fingerprints have been the gold standard for personal identification within the forensic community for more than one hundred years. It is still universal in spite of discovery of DNA fingerprint. The science of fingerprint identification has evolved over time from the early use of finger prints to mark business transactions in ancient Babylonia to their use today as core technology in biometric security devices and as scientific evidence in courts of law throughout the world. The science of fingerprints, dactylography or dermatoglyphics, had long been widely accepted, and well acclaimed and reputed as panacea for individualization, particularly in forensic investigations. Human fingerprints are detailed, unique, difficult to alter, and durable over the life of an individual, making them suitable as lifelong markers of human identity. Fingerprints can be readily used by police or other authorities to identify individuals who wish to conceal their identity, or to identify people who are incapacitated or deceased, as in the aftermath of a natural disaster

The glabrous skin on the flexor sides of hands and feet, compared to other integument regions, has thicker epidermis and more complex pattern of epidermal ridges, wherefore in microscopy is denominated as thick skin. The epidermis of this skin type has individually unique and permanent superficial patterns, called dermatoglyphics, which are maintained by regenerative potential of deep epidermal rete ridges, that interdigitate with adjacent dermis. Using light microscopy, we analyzed cadaveric big toes thick skin samples, described histology of deep epidermal ridges (intermediate, limiting, and transverse), and quantitatively evidenced their pattern of proliferation by immunohistochemical assessment of Ki67. Immunohistochemical distribution of Ki67 was confined to basal and suprabasal layers, with pattern of distribution specific for intermediate, limiting and transverse ridges that gradually transform within epidermal height. Deep epidermal ridges, interdigitating with dermal papillae, participate in construction of intricate epidermal base, whose possible role in epidermal regeneration was also discussed. Having a prominent morphology, this type of epidermis offers the best morphological insight in complexities of skin organization, and its understanding could challenge and improve currently accepted models of epidermal organization.

Growth peculiarities were followed in children of pre-school and school age (Ukrainians from Dnepropetrovsk Region, Kumyks, and Avartses from Dagestan, Tadjiks, Usbeks and Kirghizes from Middle Asia) with a special reference to exogamy estimated both by the presence or absence of relationship between their parents and by the distance between their birthplaces denoted as 0, I and II degrees of exogamy (DE). In every ethnic groups investigated with transition from 0 to DE to 1 DE increase in growth activity was noted. Transition from 1 DE to 11 DE in Ukrainians, Kirghizes and Usbeks was accompanied by some decrease in growth activity, while in Kumyks and Avartses it remains at the same level. The differences noted could be explained by various demographic conditions in population of the regions studied. As the studies demonstrated in Ukrainian children, activation in growth processes in the population with 1 DE is followed by the appearance of some peculiarities in dermatoglyphics and odontoglyphics which were absent in children with 0 DE and 11 DE. The data obtained demonstrate a certain role of genetic factors in developmental acceleration displaying at a moderate degree of exogamy.
Full Text Available Dermatoglyphics, the study of epidermal ridges on palm, sole, and digits, is considered as most effective and reliable evidence of identification. The fingerprints were studied in 300 Nepalese of known blood groups of different ages and classified into primary patterns and then analyzed statistically. In both sexes, incidence of loops was highest in ABO blood group and Rh +ve blood types, followed by whorls and arches, while the incidence of whorls was highest followed by loops and arches in Rh −ve blood types. Loops were higher in all blood groups except “A –ve” and “B –ve” where whorls were predominant. The fingerprint pattern in Rh blood types of blood group “A” was statistically significant while in others it was insignificant. In middle and little finger, loops were higher whereas in ring finger whorls were higher in all blood groups. Whorls were higher in thumb and index finger except in blood group “O” where loops were predominant. This study concludes that distribution of primary pattern of fingerprint is not related to gender and blood group but is related to individual digits.

Full Text Available Fluctuating asymmetry, the random deviation from perfect symmetry, is a widely used population-level index of developmental instability, developmental noise, and robustness. It reflects a population’s state of adaptation and genomic coadaptation. Here, we review the literature on fluctuating asymmetry of human populations. The most widely used bilateral traits include skeletal, dental, and facial dimensions; dermatoglyphic patterns and ridge counts; and facial shape. Each trait has its advantages and disadvantages, but results are most robust when multiple traits are combined into a composite index of fluctuating asymmetry (CFA. Both environmental (diet, climate, toxins and genetic (aneuploidy, heterozygosity, inbreeding stressors have been linked to population-level variation in fluctuating asymmetry. In general, these stressors increase average fluctuating asymmetry. Nevertheless, there have been many conflicting results, in part because (1 fluctuating asymmetry is a weak signal in a sea of noise; and (2 studies of human fluctuating asymmetry have not always followed best practices. The most serious concerns are insensitive asymmetry indices (correlation coefficient and coefficient of indetermination, inappropriate size scaling, unrecognized mixture distributions, inappropriate corrections for directional asymmetry, failure to use composite indices, and inattention to measurement error. Consequently, it is often difficult (or impossible to compare results across traits, and across studies.

To assess the correlation between different cheiloscopic patterns with the terminal planes in deciduous dentition. Three hundred children who are 3-6 years old with complete primary dentition were recruited, and the pattern of molar terminal plane was recorded in the pro forma. Lip prints of these children were recorded with lipstick-cellophane method, and the middle 10 mm of lower lip was analyzed for the lip print pattern as suggested by Sivapathasundharam et al . The pattern was classified based on Tsuchihashi and Suzuki classification. Type II (branched) pattern was the most predominant cheiloscopic pattern. The predominant patterns which related to the terminal planes were as follows: Type IV (reticular) and Type V (irregular) pattern for mesial step, Type IV (reticular) pattern for distal step, and Type I (complete vertical) pattern for flush terminal plane. No significant relationship was obtained on gender comparison. Lip prints can provide an alternative to dermatoglyphics to predict the terminal plane in primary dentition. Further studies with larger sample size are required to provide an insight into its significant correlations.

Fingerprints are considered to be one of the most reliable methods of identification. Identification of an individual plays a vital part of any medico-legal investigations. Dermatoglyphics is a branch of science that studies epidermal ridges and ridge patterns. Epidermal ridges are polygenic characteristics that form intrauterine 10-18 weeks and considered fully developed by the sixth month of fetal growth. Fingerprints are permanent morphological characteristics and criminal detection based on fingerprints is based on the principle that no two people can have identical fingerprints. Sex determination from fingerprints has been examined in different population. In this study we aimed to study fingerprint ridge density in Turkish population sample of Baskent University students. Fingerprints were obtained from 118 women, 88 men a total of 206 students aged between 17 and 28 years old by means of simple inking method. Fingerprints from all right and left hands fingers were collected in three different area of each. The ridges on fingerprints were counted diagonally on squares measuring 5 mm × 5 mm on radial, ulnar and inferior areas. The fingerprint ridge density in radial, ulnar and inferior areas and between sexes was compared statistically Mann Whitney U test and Friedman test. The ridge density was significantly greater in women in every region studied and in all fingers when compared to men. The fingerprint ridge density in the ulnar and radial areas of the fingerprints was significantly greater than the lower area. Fingerprint ridge density can be used by medico-legal examination for sex identification. Copyright © 2015 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

Kabuki syndrome (KS) is a multiple congenital anomaly syndrome characterized by specific facial features, mild to moderate mental retardation, postnatal growth delay, skeletal abnormalities, and unusual dermatoglyphic patterns with prominent fingertip pads. A 3.5 Mb duplication at 8p23.1-p22 was once reported as a specific alteration in KS but has not been confirmed in other patients. The molecular basis of KS remains unknown. We have studied 16 Spanish patients with a clinical diagnosis of KS or KS-like to search for genomic imbalances using genome-wide array technologies. All putative rearrangements were confirmed by FISH, microsatellite markers and/or MLPA assays, which also determined whether the imbalance was de novo or inherited. No duplication at 8p23.1-p22 was observed in our patients. We detected complex rearrangements involving 2q in two patients with Kabuki-like features: 1) a de novo inverted duplication of 11 Mb with a 4.5 Mb terminal deletion, and 2) a de novo 7.2 Mb-terminal deletion in a patient with an additional de novo 0.5 Mb interstitial deletion in 16p. Additional copy number variations (CNV), either inherited or reported in normal controls, were identified and interpreted as polymorphic variants. No specific CNV was significantly increased in the KS group. Our results further confirmed that genomic duplications of 8p23 region are not a common cause of KS and failed to detect other recurrent rearrangement causing this disorder. The detection of two patients with 2q37 deletions suggests that there is a phenotypic overlap between the two conditions, and screening this region in the Kabuki-like patients should be considered.

Analysis of fingerprints and palm prints at the crime scene is vital to identify the suspect and establish a crime. Dermatoglyphics can even be valuable in identification of a dismembered hand during medicolegal investigations to establish the identity of an individual in cases of mass disasters/mass homicides. The present research studies the variation in ridge density in different areas of the palm prints among men and women. The four prominent areas were analysed on the palm prints that included central prominent part of the thenar eminence (P1), hypothenar region; inner to the proximal axial triradius (P2), medial mount; proximal to the triradius of the second digit (P3) and lateral mount; proximal to the triradius of the fifth digit (P4). The mean palm print ridge density was significantly higher among women than men in all the designated areas in both hands except for the P3 area in the right hand. Statistically significant differences were observed in the palm print ridge density between the different palm areas in men and women in right and left hands. No significant right-left differences were observed in the palm print ridge density in any of the four areas of palm prints among men. In women, right-left differences were observed only in the P3 and P4 areas of palm prints. This preliminary study indicates that though the palm print ridge density is a sexually dimorphic variable, its utility for estimation of sex in forensic identification may be limited owing to significant overlapping of values.

Full Text Available Seventy five female workers employed in the cashew nut industry in Karnataka to slice off the outer hard shells from the nuts and thus exposed to the chashew nut shell oil had a characteristic cauterization type of reaction manifesting as brownish-black, thickened sheets of dead skin covering the dorsal as well as the palmar aspects of hands including the fingers and feet. Smaller but similer lesions were also seen on these parts of the forearms, abdomen, neck and face which were not covered with clothes. The fingers were thinned and tapering and several nails of the hands and feet were thickened, discolored and eaten away. The other changes included loss of the dermatoglyphic patterns, maceration of the hands, small pits on the finger tips and pitted keratolysis seen in some cases only. Similar changes were also seen on the feet of both the male workers exposed to the same oil, in the section which extracts the oil from the sliced shells. In contrast 29, feamle wokers engaged to peel off the thin reddish covering on the cashew nut had normal hands and feet, except for the two callosities on the flexural aspect of the proximal phalanx of the right middle finger and proximal interphalangeal joint of the right index finger respectively, caused by the friction of the peeling knife. An open patch test with the cashew nut shell oil used as such in 17 workers produced a cauterization type of reaction in 32 workers irrespective of the nature of their duties, while the standard occluded patch test with 10% cashew nut shell oil in polyethylene glycol showed a mild cauterization type of reaction in only 6 workers. Patch tests with 1% and 0.1% concentrations of the shell oil were negative in all the workers. Two barrier creams tested to protect the workers from the cashew nut shell oil produced reasonably effective results within a week.

Full Text Available The Kabuki Make-up Syndrome is a rare congenital anomaly, characterized by five fundamental features, the " Pentad of Niikawa": dysmorphic facies, skeletal anomalies; dermatoglyphic abnormalities, mild to moderate mental retardation, postnatal growth deficiency. Orthopaedic aspects include scoliosis, malformation of spinal column and ribs, delay in skeletal maturation, congenital deslocation of the hip and patelar dislocation, among others.With the purpose of drawing attention to this diagnostic, the case of five years old brazilian female patient is presented.It´s convenient to present this case to focus on the existance of this syndrome and all its complexity and, therefore, provide help for future diagnosis.A Síndrome da Maquiagem de Kabuki é uma anomalia congênita rara, caracterizada por cinco características fundamentais, a " Pêntade de Niikawa": face dismórfica; anomalias esqueléticas; alterações dermatoglíficas; leve a moderado retardo mental; retardo do crescimento pós-natal. Os aspectos ortopédicos incluem escoliose, malformação da coluna vertebral e costelas, maturação óssea retardada, luxação congênita do quadril e luxação patelar, entre outras.Com o objetivo de chamar a atenção para este diagnóstico, é apresentado o caso de paciente cinco anos de idade, brasileira, feminina, portadora da síndrome.É conveniente apresentar este caso para atentar a existência dessa síndrome e toda sua complexidade e, assim, auxiliar futuros diagnósticos.

The need for personal identification is growing in many avenues of society. To "identify" a person is to establish a link between his or her observed characteristics and those previously stored in a database. To "authenticate" is to decide whether or not someone is the person he or she claims to be. These two objectives can now be achieved by analysing biometric data and genetic prints. All biometric techniques proceed in several stages: acquisition of an image or physical parameters, encoding them with a mathematical model, comparing the results of this model with those contained in the database, and calculating the error risk. These techniques must be usable worldwide and must examine specific and permanent personal data. The most widely used are facial recognition, digital prints (flexion folds and dermatoglyphs, that offer the advantage of leaving marks), and the surface and texture of the iris. Other biometric techniques analyse behaviours such as walking, signing, typing, or speaking. Implanted radio-transmitters are another means of identification. All these systems are evaluated on the basis of the same parameters, namely the false rejection rate, the false acceptance rate, and the failure-to-enrol rate. The uses of biometrics are increasing and diversifying, and now include national and international identification systems, control of access to protected sites, criminal and victim identification, and transaction security. Genetic methods can identify individuals almost infallibly, based on short tandem repeats of 2-5 nucleotides, or microsatellites. The most recent kits analyze 11-16 independent autosomal markers. Mitochondrial DNA and Y chromosome DNA can also be analyzed. These genetic tests are currently used to identify suspected criminals or their victims from biological samples, and to establish paternity. Personal identification raises many ethical questions, however, such as when to create and how to use a database while preserving personal freedom

Identical anomalies produced by different causes such as aneuploidy, gene mutation, teratogenic chemicals, and certain surgical procedures are a clear indication that embryonic primordia respond as units in the production of developmental anomalies of anatomic structure. Hence, they must also act as units during normal ontogeny. The presence of identical malformations in different mammalian species identifies developmental and anatomic homology by virtue of descent from a common ancestor. These dys- and orthomorphogenetically reactive units are the equivalents of the classic experimental embryologist's epimorphic fields, which are those units of the embryo in which the development of complex structures appropriate to the species is determined and controlled in a spatially coordinated, temporarily synchronous, and epimorphically hierarchical manner that expresses both species-nonspecific (that is, phylogenetic) and species-specific genetically coded developmental information. Thus, it is as important for pathologists as it is for clinical geneticists to steep themselves in the art and science of phenotype analysis and to be able to do all of those studies, including anthropometry, dermatoglyphics, and growth analysis, that are required to arrive at inferences of cause and pathogenesis from the phenotype. There is probably one other incentive besides the ethical and intellectual ones to do this and to do it as well as possible, namely, the medico-legal consequences. If pathologists fail to illuminate the causal genesis of a given case to aid in preventing recurrence, then, in short order, they might be held equally as liable as clinicians for missing high recurrence risk genetic diagnoses. These depressing considerations aside, it is important to close on a positive note. As at the outset, we want to emphasize once more that, without question, this is the most exciting time to be working in the field of developmental pathology. In this specialty a marriage is

We analysed scale morphology and micro-structure from five different body regions using scanning electron microscopy (SEM) across all nine recognized subgenera of the monitor lizard genus Varanus including 41 different species investigated. As far as we are aware, this qualitative visual technique was applied by us for the first time to most monitor lizard species and probably also to the primary outgroup and sister species Lanthanotus borneensis. A comprehensive list of 20 scalation characters each with up to seven corresponding character states was established and defined for the five body regions sampled. For the phylogenetic approach, parsimony analyses of the resulting morphological data matrix as well as Bremer and bootstrap support calculations were performed with the software TNT. Our results demonstrate that a variety of micro-ornamentations (i.e., ultra- or micro-dermatoglyphics) as seen in various squamate groups is hardly present in monitor lizards. In several species from six out of nine subgenera, however, we found a honeycomb-shaped micro-structure of foveate polygons. Two further samples of Euprepiosaurus Fitzinger, 1843 exhibit each another unique microscopic structure on the scale surface. Notably, the majority of species showing the honeycombed ultra-structure inhabit arid habitats in Australia, Africa and the Middle East. Therefore, it can be inferred that this microscopic scalation feature, which has also been identified in other desert dwelling lizard species, is taxonomically and ecologically correlated with a xeric habitat type in varanids, too. In addition, the systematic affiliation of V. spinulosus, an endemic monitor lizard species from the Solomon Islands with an extraordinary scale shape, is discussed in the light of current hypotheses about its phylogenetic position within the Varanidae. Due to its unique scalation characteristics, in combination with other morphological evidence, a new monotypic subgenus, Solomonsaurus subgen. nov
considering all possible situations, especial attention is given to review some converging epidemiological and genetical methods and techniques. Among them, we stress the case studies on lab methodologies, as dermatoglyphics, and on quantitative procedures, as path analysis. Some studies are taken as examples for application, since they have been object of research in our country: leprosy, hydrargyrism and schizophrenia.
