Dermatoglyphic Profiles of Competitive Athletes: CrossFit and Ultra-Marathon / Perfiles Dermatoglíficos de Deportistas Competitivos: CrossFit y Ultramaratón

SUMMARY: In the sports field, sports are usually classified according to the predominance of the energy system used during the competition; sports like Crossfit and ultra-marathon could be totally opposite due to the needs of athletes to achieve good places. Due to the above, the objective was established to compare the dermatoglyphic profiles of CrossFit and Ultra-marathon athletes according to the predisposition of the energy systems, aerobic and anaerobic, used in the competitions. Cross-sectional descriptive study, where the dermatoglyphic profile of 21 athletes of national presence (10 crossfit and 11 ultra-marathon runners) was determined, through the Computerized Dermatoglyphic System, brand Salus Dermatoglifia, according to the Cummins and Midlo protocol, which consists of taking the fingerprints of the 10 fingers of the hands. The fingerprint designs of the human being (arch, loop and whorl) and the elements contained in them (nucleus and delta) were analyzed, differences were established through the Analysis of Variance test in the SPSS V.25 statistical package. The results show significant differences between the average scores of the line count of both disciplines (108 and 165), being higher in ultra-marathon runners, associated with greater aerobic resistance. Another significant and relevant finding was the presence of arch-type fingerprints only in CrossFit athletes associated, along with low line count, with strength and power. It is concluded that Crossfit and Ultra-marathon athletes have dissimilar natural physical characteristics, which is why they participate and excel in different sports where they have enhanced their natural physical abilities through training.

En el ámbito deportivo, los deportes suelen clasificarse según el predominio del sistema energético utilizado durante la competición; Deportes como el Crossfit y la ultramaratón podrían ser totalmente opuestos debido a las necesidades de los deportistas de conseguir buenos lugares. Debido a lo anterior, se estableció como objetivo comparar los perfiles dermatoglíficos de atletas de CrossFit y Ultramaratón según la predisposición de los sistemas energéticos, aeróbico y anaeróbico, utilizados en las competencias. Estudio descriptivo transversal, donde se determinó el perfil dermatoglífico de 21 deportistas de presencia nacional (10 crossfit y 11 ultramaratonistas), a través del Sistema Dermatoglífico Computarizado, marca Salus Dermatoglifia, según el protocolo Cummins y Midlo, el cual consta de tomando las huellas dactilares de los 10 dedos de las manos. Se analizaron los diseños dactilares del ser humano (arco, asa y verticilo) y los elementos contenidos en ellos (núcleo y delta), se establecieron diferencias mediante la prueba de Análisis de Varianza en el paquete estadístico SPSS V.25. Los resultados muestran diferencias significativas entre las puntuaciones medias del recuento de líneas de ambas disciplinas (108 y 165), siendo superiores en los corredores de ultramaratón, asociado a una mayor resistencia aeróbica. Otro hallazgo significativo y relevante fue la presencia de huellas dactilares tipo arco sólo en atletas de CrossFit asociadas, junto con un bajo número de líneas, con fuerza y potencia. Se concluye que los atletas de Crossfit y Ultramaratón tienen características físicas naturales disímiles, por lo que participan y destacan en diferentes deportes donde han potenciado sus capacidades físicas naturales a través del entrenamiento.

Limite ético para confirmar identidade pelos caracteres morfológicos / Ethical limits to confirming identity by morphological features / Límite ético para confirmar la identidad por caracteres morfológicos

Resumo O desenvolvimento de novas tecnologias fez nascer ferramentas que auxiliam no processo de identificação de indivíduos, possibilitando confirmar identidades e ajudando a solucionar crimes, ao permitir confirmar o encontro de pessoas desaparecidas ou vítimas de acidentes, por exemplo. Entretanto, um importante questionamento ético precisa ser observado: os fins sempre justificam os meios? A identificação facial a partir de imagens coletadas por câmeras de circuito fechado de televisão ou a análise de registros fotográficos são capazes de confirmar a identidade de alguém inequivocamente? Impressões digitais ou labiais podem ser utilizadas, em qualquer hipótese, em um confronto dactiloscópico? O conhecimento sobre as limitações dos métodos técnicos científicos utilizados em comparações de caracteres morfológicos permite que o resultado do perito papiloscopista atenda a dois princípios basilares constitucionais: a legalidade e o direito da pessoa humana. Ao respeitá-los, estará agindo conforme os limites éticos.

Abstract Technological advancements have generated tools to help with identifying individuals, allowing to verify identities and solve crimes by confirming found missing persons or accident victims, for example. An important ethical question, however, arises: do the ends always justify the means? Can facial identification from images collected by closed-circuit television cameras or analysis of photographic records confirm someone's identity unequivocally? Can fingerprints or lip prints be used for any dactyloscopy? Knowing the limitations of scientific technical methods used in morphological comparisons allows examiners to comply with two fundamental constitutional principles: that of legality and right of the human person. By respecting them, examiners will be acting according to ethical limits.

Resumen El desarrollo de nuevas tecnologías dio lugar a herramientas que ayudan en el proceso de identificación de personas, lo que posibilita la confirmación de identidades y contribuye a la resolución de delitos al permitir confirmar, por ejemplo, a personas desaparecidas o víctimas de accidentes. Sin embargo, es necesario observar una cuestión ética importante: ¿el fin siempre justifica los medios? ¿La identificación facial desde imágenes captadas por cámaras de circuito cerrado de televisión o el análisis de registros fotográficos puede confirmar inequívocamente la identidad de una persona? ¿Se pueden utilizar huellas dactilares o labiales, bajo cualquier circunstancia, en un enfrentamiento dactiloscópico? El conocimiento sobre las limitaciones de los métodos técnicos y científicos utilizados en las comparaciones de caracteres morfológicos permite que el resultado del perito en papiloscopía responda a dos principios constitucionales básicos: la legalidad y el derecho de la persona humana. Al respetarlos se estará actuando dentro de los límites éticos.

Dermatoglyphic and acoustic analysis of singing voices: a multiple case preliminary report

ABSTRACT Purpose: to identify genetically enhanced physical skills (speed, strength, endurance and motor coordination), provided by the dermatoglyphic method and to analyze the preliminary correlation between dermatoglyphic and acoustic data of lyrical and pop singers. Methods: the study was approved by the Ethics and Research Committee. Four male singers were evaluated (two lyrical and two pop singers), 31-53 years old. Data collection and analysis procedures comprised (1) Survey -Self-Perception of Vocal Characteristics in Singers (vocal habits, voice performance and phenotypic characteristics); (2) Dermatoglyphic Profile (fingerprint image digitalization: predominance of digital drawings (Arch, Loop and Whorl); scores of deltas (D10); the Total Ridge Count (TRC); digital formula and dermatoglyphic profile (aerobic, anaerobic and mix)); (3) Acoustic Analysis (the Expression Evaluator script application to the audio recordings: f0, intensity, spectral slope and long-term average spectrum - LTAS values); and (4) Integrated (Statistical) Analysis; cluster analysis. Results: correlations were found between dermatoglyphic variables (Arch, Loop, Whorl, D10, TRC) and acoustic parameters (f0 (median); intensity (asymmetry); spectral slope (mean); and LTAS (SD)). The dermatoglyphic profile did not segregate singing styles. Conclusion: the dermatoglyphic profiles showed a preliminary correlation with the acoustic vocal measures, especially f0 and LTAS measures.

Dermatoglifia como medio de hallazgo de diabetes mellitus: revisión sistemática / Dermatoglyphics as a means of finding diabetes mellitus: a systematic review

Introducción. La diabetes mellitus (DM) es una de las enfermedades crónicas más comunes, siendo una de las causas principales de mortalidad de la población mun-dial. La dermatoglifia es empleada como instrumento para el hallazgo de ciertos aspectos biológicos en diferentes poblaciones. Objetivo. Reconocer, a partir de una revisión sistemática, la relevancia que tiene la dermatoglifia como medio de hallazgo de diabetes mellitus. Metodología. Revisión de literatura científica en bases de datos como Sciencedi-rect, PubMed, Scopus y BVS, en las cuales se extrajo información después de co-rrer la ecuación de búsqueda con términos MESH. Posteriormente, fueron revisados para incluir aquellos artículos relacionados con DM y dermatoglifia. Para todo el proceso se siguió la metodología PRISMA, evaluando los artículos con la escala de sesgo de Cochrane y el nivel de evidencia y recomendación con escala SIGN. Resultados. Después de una revisión de 475 artículos, se incluyeron ocho artículos, y al ser evaluados fueron clasificados cinco artículos 2+ y tres 2-, con nivel de reco-mendación D. Conclusión. La dermatoglifía es una herramienta útil como medio de detección de la DM. Sin embargo, es necesario realizar estudios de cohortes para demostrarlo en di-ferentes poblaciones, como la colombiana. En ese sentido, se encuentra que el 70% de los artículos revisados demuestran que la predicción de hallazgo de DM es efectiva. Sin embargo, el 30% de las investigaciones dentro de esta revisión no consideran que sea una herramienta lo suficientemente óptima para descubrir la patología en la población.

Introduction. Diabetes mellitus (DM) is one of the most common chronic diseases, be-ing one of the main causes of mortality in the world population. Dermatoglyphics is used as an instrument for the discovery of certain biological aspects in different populations.Objective. To recognize, by doing a systematic review, the relevance of dermato-glyphics as a means of finding diabetes mellitus. Methodology. Review of scientific literature in databases such as Sciencedirect, PubMed, Scopus, and VHL, in which information was extracted after running the search equation with MESH terms. After that, they were revised to include those articles related to DM and dermatoglyphics. For the entire process, the PRISMA methodology was followed, evaluating the articles with the Cochrane bias scale and the level of evidence and recommendation with the SIGN scale. Results. After a review of 475 articles, eight articles were included, and when evalu-ated, five articles were classified as 2+ and three as 2-, with a level D recommendation. Conclusion. Dermatoglyphics is a useful tool as a means of detecting DM. However, it is necessary to carry out cohort studies to demonstrate this in different populations, such as the Colombian population. 70% of the reviewed articles show that the prediction of DM finding is effective. Nevertheless, 30% of the investigations within this review do not consider it to be a sufficiently optimal tool to discover the pathology in the population

Dermatoglifia y fuerza muscular en deportistas de baloncesto universitario / Dermatoglyphics and muscle strength in college basketball players / Dermatoglifia e força muscular em atletas de basquete universitári

RESUMEN El baloncesto es un deporte que requiere capacidades físicas para su desenvolvimiento en cualquier nivel de competencia; la fuerza es uno de los parámetros a evaluar que más exactitud precisa y que puede ayudar a llevar al deportista a su máximo potencial, por esto el objetivo del estudio fue determinar la relación entre las variables dermatoglifia y fuerza muscular en las posiciones de juego del baloncesto universitario, teniendo en cuenta el perfil antropométrico, en jugadores (mujeres y hombres) entre los 17 y 23 años. La muestra fue con 15 atletas de la selección de baloncesto, donde se evaluaron variables dermatoglificas (metodología propuesta por Cummins & Midlo, 1942), medidas antropométricas (la báscula InBody 770 y tallímetro SECA), posición de juego de cada individuo y test de fuerza muscular (T-force, modelo TF-100). Se encontró que la variable de dermatoglifia que más correlación (alta y moderada) tuvo con la prueba de fuerza muscular fueron los Arcos y dentro de este se encontraban los Postes, quienes en esta posición de juego mostraron mayor relación (r= 0,525 p= 0,045). Se demostró que, puede encontrar un lazo entre dos variables como dermatoglifia y fuerza muscular, sin embargo, es importante contar con una muestra más amplia y discriminarla por género, para así tener mayor exactitud.

ABSTRACT Basketball is a sport that requires physical abilities for its development at any level of competition; strength is an evaluated parameter that is more accurate than others and that can help to take the athlete to their maximum potential. For this reason, the objective of this study is to determine the relationship between the dermatoglyphics and muscle strength variables in university basketball playing positions, taking into account the anthropometric profile, in players (women and men) between 17 and 23 years old. The sample consisted of 15 athletes from the basketball team, where dermatoglyphic variables (methodology proposed by Cummins & Midlo, 1942), anthropometric measurements (the InBody 770 scale and SECA height rod), playing position of each individual, and muscle strength test (T-force, model TF-100) were evaluated. The dermatoglyphics variable that had the most correlation (high and moderate) with the muscle strength test were the arches, and within these, were the posts, who, in this playing position, showed the greatest relationship (r = 0.525 p = 0.045). It was shown that you can find a link between two variables such as dermatoglyphics and muscle strength, however, it is important to have a larger sample and discriminate it by gender, in order to have a higher accuracy.

SUMÁRIO O basquete é um esporte que requer habilidades físicas para seu desenvolvimento em qualquer nível de competição; a força é um dos parâmetros a serem avaliados mais precisos e que podem ajudar a levar o atleta ao seu potencial máximo; por esse motivo, o do estudo foi determinar a relação entre as variáveis dermatoglíficas e a força muscular nas posições de jogo de basquete de universidade, considerando o perfil antropométrico, em jogadores (mulheres e homens) entre 17 e 23 anos de idade. A amostra foi composta por 15 atletas do time de basquete, onde variáveis dermatoglíficas (metodologia proposta por Cummins & Midlo, 1942), medidas antropométricas (escala InBody 770 e estadiômetro SECA), posição de jogo de cada indivíduo e teste de força muscular (força T, modelo TF-100). Para análise estatística, foi realizado no software SPSS versão 22, com tendência central (média e desvio padrão). Verificou-se que a variável dermatoglyphic que teve a maior correlação (alta e moderada) com o teste de força muscular foram os Arcos e dentro deste foram os posts, que nesta posição de jogo apresentaram a maior relação (r = 0,525 p = 0,045). Foi demonstrado que, se é possível encontrar um vínculo entre duas variáveis, como dermatoglifos e força muscular, é importante ter uma amostra maior e discriminá-la por sexo, a fim de obter maior precisão.

Huellas dactilares: origen, usos y desafíos que genera la incapacidad para su registro / Fingerprints: origin, uses and challenges in the face of its verification failure

Considerando que las huellas dactilares son impresiones de las crestas epidérmicas de los dedos con un patrón único, irrepetible y permanente, estas son la base del método biométrico más empleado en la actualidad. Entre sus diversos usos destaca la identificación para múltiples actividades como acceder al trabajo o a teléfonos celulares, la operación de cuentas bancarias, las investigaciones criminales, etcétera. La ausencia o deterioro de las crestas epidérmicas, denominada adermatoglifia, impide la identificación por biometría dactilar. La adermatoglifia se origina por múltiples causas, incluyendo las enfermedades dermatológicas, lesiones traumáticas de los dedos, denervación, envejecimiento, quimioterapia, entre otras. Abordamos brevemente el origen, usos y sistemas para el registro de las huellas dactilares. El objetivo principal es enfatizar la existencia de personas con incapacidad para registrar sus huellas, una condición relevante por el riesgo potencial de discriminación, especialmente cuando el registro de las huellas es obligatorio.

Considering that fingerprints are impressions of the epidermal ridges of the fingers with a unique, unrepeatable, and permanent pattern, they are the basis of the biometric identification method most used today. Among its various uses stand out identification for multiple activities such as authentication to access work and cell phones, operation of bank accounts, criminal investigations, etc. The absence or deterioration of the epidermal ridges, called adermatoglyphia, prevents identification by finger biometrics. Adermatoglyphia originates from multiple causes, including several skin diseases, traumatic injuries of the fingers, denervation, aging, chemotherapy, among others. The origin, uses, and systems for fingerprints verification are briefly addressed here. The main objective is to emphasize the existence of people with fingerprint verification failure, a relevant condition due to the potential risk of discrimination, especially when fingerprint verification is mandatory.

A CHEILOSCOPIC STUDY IN RELATION TO FINGER PRINTS OF EBIRA ETHNIC GROUP, KOGI STATE, NIGERIA

Lip prints permanency, finger print as well as the number of easily observable and measurable characteristics have been one of the most suitable parameters for studying personal identification. The study, aimed at determining the relationship between lip and finger prints with relation to sex among Ebira Ethnic Group of Nigeria Four hundred and. ten subjects (205 males and 205 females) aged between 18-65 years, participated in the study. Fischer's formula or infinite population was used to calculate the optimal sample size. Lip prints of the participants were collected using lip gloss and microscopic slides pressed gently on the lips, ink powder is slightly blown on the slides to show the prints.A HP G3110 Scanjet Scanner (9000 x 4800 dpi resolution) which is a classical type of scanner was used to determine digital patterns of the fingers. SPSS version 20.0 was used in analysing the data. Statistical significance was put into consideration using one-way Analysis of Variance (ANOVA) when (P = 0.05 or P ? 0.05). The predominant lip print pattern of the upper and lower lip of both sexes distributed as Type II and Type IV which are sexually dimorphic, on both hands the most prominent finger print pattern was the loop for both female and males which shows no significant sex difference. The association between lip and finger prints was significant. This is very important in personal identification in forensics.

Association between ABO, Rh blood groups, lip and dermatoglyphic patterns, and nonsyndromic oral clefts A case–control study

Objective: The objective of the study is to determine the association between nonsyndromic oral clefts (OC) in children and ABO, Rh blood groups, lip, and dermatoglyphic patterns of their unaffected parents. Methods: This case–control study was conducted at a tertiary cleft center in Chennai, India, among 240 individuals comprising 80 units (40 cases and controls, respectively). Each unit (triad) was constituted by a child (0–12 years of age) either born with nonsyndromic OC (cases) or with no diagnosed congenital anomaly (control) and their unaffected parents (mother and father). ABO and Rh blood groups, specific lip print, fingerprint pattern, and palmar asymmetry were recorded for each individual. Strength of association of related factors was assessed by multivariable logistic regression reported as adjusted odds ratios and 95% confidence interval. Results: A1-positive blood group was found to be considerably higher among case mothers (14.39 [1.57–32.27]). A higher odds of OCs were observed among case mothers with whorl lip pattern (1.51 [1.16–3.17]) and radial loop pattern in fingers (1.44 [1.09–2.31]) relative to controls. In addition, palmar asymmetry was distinctively higher among case parents compared to controls (P < 0.01). Conclusion: Findings indicate that A1-positive blood group, higher frequency of whorl lip, and radial loop finger patterns in mothers and higher ulnar loop pattern in fathers and palmar asymmetry in both parents increases odds of occurrence of OC among their offspring. These identifiable traits offer potential scope for better service planning among resource-constrained disadvantaged communities in India.

In eczema patients, loop and whorl pattern was found in (44.74%) followed by 34.23% loop, 22.43% arch and 1.86% composite pattern.Conclusion: The palmar pattern intensities were increased in both sexes, while the digital pattern intensities were increased in males and decreased in females. TFRC was increased in males and decreased in female patients. In both cases and controls, TFRC was more in males than females.A-b count showed a significant reduction in both sexes

A Study of Correlation between Dermatoglyphic Angle and Blood Pressure.

To resolve the biomedical problems, palmar dermatoglyphics has been used as a method. For the screening of hypertension palmar prints can be used. We wanted to determine the correlation between dermatoglyphic angle and blood pressure.METHODSThis is a cross sectional study. Palmar prints of right and left hands were taken with the help of inkpad. Blood pressure was also measured and ATD angle of both the hands were measured with the help of goniometer in 200 females and 200 male subjects of North India. Percentages, Pearson’s chi-square test, Student independent t test, one-way ANOVA were used. A p value < 0.05 was considered statistically significant. Statistical analysis was conducted using SPSS version 20.RESULTSHypertension I and II were recorded for 7.0 % (6.0% of males and 6.0 % of females) and 2.3 % subjects (3.0% of males and 1.5 % females). Overall 28.3% of subjects had prehypertension. A statistically significant difference was observed in the value of left hand ATD angle for the comparison of hypertensive and non-hypertensive subjects.CONCLUSIONSDermatoglyphics can be used as a tool for the prediction of various diseases with a genetic link. Several studies nowadays show association of dermatoglyphic angle with hypertension.

Comparison of dermatoglyphic patterns in oral leukoplakia and oral submucous fibrosis patients

Background: Genetics plays an important role in the detection of an Oral potentially malignant lesion. A major contributor to genetic study is Dermatoglyphics or the study of fingerprints and lines of palmer and plantar surfaces. Many researchers have used dermatoglyphics to connect genetics with oral lesions and malignancies. Thus, the current study has been conducted to find out an association between dermatoglyphic patterns and oral leukoplakia, oral submucous fibrosis and healthy subjects.Methods: The present study is conducted on subjects that have been already diagnosed with oral lesions. Fingerprint patterns (whorled, loop and arch) were evaluated by utilizing fingerprints.Results: The present study showed that the loop pattern was common in all three subjects. The frequency of whorled and arch pattern is decreased in oral leukoplakia and oral submucous fibrosis that healthy subjects. Arch pattern is comparatively decreased in subjects with oral leukoplakia than oral submucous fibrosis and there is a decrease in the frequency of whorled patterns in OSMF as compared to oral leukoplakia.Conclusions: Authors conclude that simply by observing the whorled and arch patterns in a subject, authors can hypothesize that risk of occurrence of oral leukoplakia and oral submucous Fibrosis and take preventive measures against the said lesions.

Dermatoglyphic traits of brazilian golfers / Traços dermatoglíficos dos golfistas brasileiros

ABSTRACT Played all over the world, golf has gained popularity, for it is a sport that depends on individual abilities. For this reason the search for tools that aim to seek and guide its respective talented players has become very important. Therefore, this study had the objective of comparing the distribution of the dermatoglyphic indicators of high performance golfers and of a group control of non-athletes. The sample was composed of 46 individuals with paired age and gender, divided into two groups: the Group Golf (GG), composed of 23 golfers, and the Group Control (GC), composed of 23 individuals control randomly selected. The golfers, part of the Project Golf Brazil of the Brazilian Golf Confederation, were between 11 and 21 years old. The results demonstrated that the number of lines in the pattern was of six possible variables of fingerprint (MESQL1, MESQL2, MESQL4, MESQL5, SQTLE, SQTL) is significantly higher in the golfers (GG) when compared to the group control (GC). When observed the qualitative variables, i. e., the pattern type, significant diferences where observed between the groups, since the golfers (GG) presented more Radial Loops (RL) in MDT5 when compared to the group control (GC). The results found in this study demonstrated that the dermatoglyphic profile of high performance golfers differ from the non-athlete population.

RESUMO Jogado em todo o mundo, o golfe está ganhando popularidade, sendo um esporte que depende das habilidades individuais, tornando-se importante a busca por ferramentas que visem buscar e orientar seus respectivos talentos. O presente estudo teve por objetivo comparar a distribuição dos indicadores dermatoglíficos de golfistas de alto rendimento e de um grupo controle de não atletas. A amostra foi composta por 46 indivíduos com idade e sexo pareados, divididos em dois grupos: o Grupo Golf (GG), composto por 23 golfistas e o Grupo Controle (GC), composto por 23 indivíduos controle aleatoriamente selecionados. Os golfistas, parte do Projeto Golf Brasil da Confederação Brasileira de Golfe, tinham idade entre 11 e 21 anos. Os resultados demonstram que o número de linhas no padrão de seis possíveis variáveis de impressão digital (MESQL1, MESQL2, MESQL4, MESQL5, SQTLE, SQTL) é maior nos golfistas (GG) quando comparado ao grupo controle (GC). Quando observadas as variáveis qualitativas, ou seja, o tipo de figura, observaram-se diferenças significativas entre os grupos, visto que os Golfistas (GG) apresentaram maior quantidade de Presilha Radial (LR) no MDT5 quando comparados ao grupo controle (GC). Os resultados encontrados neste estudo demonstraram que o perfil dermatoglífico de golfistas de alto rendimento difere da população não atleta.

Correlation of dermatoglyphics with emotional intelligence amongst medical students

Background: Dermatoglyphics is the study of patterns of epidermal ridges on the volar surfaces of the skin. Thisis said to be associated with multiple intelligences in humans based on the fact that the neocortex anddermatoglyphic prints are developing simultaneously during embryogenesis and they are both geneticallydetermined. Hence this cross-sectional observational study to correlate Emotional Intelligence and dermatoglyphicpatterns.A self-evaluating questionnaire was applied on 100 M.B.B.S students, fingerprints of whom were collected using‘Ink and Paper’ method. The subjects were then categorized into two groups- Category A including subjects withEQ>120; and Category B including subjects with EQ<120. The collected fingerprints were categorized into PlainArches, Tented Arches, Ulnar Loops, Radial Loops, Whorls and Composite. The data was then tabulated andobserved for recurrence of patterns in each category of EQ and was statistically analyzed.Results: In Category A, the most recurring pattern is Ulnar Loop. In Category B, the most recurring fingerprintpattern is Ulnar Loop in all digits except the L4 and R4 in which Whorl is the most recurring type. The chi squaretest of significance and exact test of association were applied and ‘p’ values were calculated and none of themwere <0.05.Conclusion: The results correspond with the observations made in a previous study correlating dermatoglyphicsand IQ amongst medical students. Hence, the aforementioned results may be suggestive of some correlationbetween dermatoglyphics and EQ. However, the lack of statistical significance may be attributed to the modestsample size. Further research is required in this regard to validate the results of this study.

A case–control study of fingerprint patterns of both hands in persons with and without schizophrenia

Background: Schizophrenia is a complex disorder. Abnormal brain functions and aberrant fingerprint patterns are under study to aid in diagnosing schizophrenia. Objectives: The objectives of the study were to study the finger and palm print patterns in patients with schizophrenia, to compare the patterns with those of healthy controls, to find if specific patterns exist in patients with schizophrenia, a cross-sectional comparative case–control study of finger and palm patterns in patients with schizophrenia and age-matched healthy controls was done in a tertiary care teaching hospital in the district of Kancheepuram, Tamil Nadu. Materials and Methods: Finger and palm print pattern of 100 patients with schizophrenia and 100 age-matched controls was taken using the standard technique with India ink and studied. Demographic details of both the case and control groups were also collected. Patterns of both the hands of the two groups were analyzed. Descriptive analysis was done. Chi-square test and independent t-test were used for analyzing the mean difference between the variables of the two groups. Results: The frequency of arches was more in cases than controls. The frequency of radial loops was twice in cases than controls. The ulnar loops were less in cases. The mean total finger ridge count and total A-B ridge count were significantly lower in schizophrenia patients than in controls. The mean atd angle was significantly higher in cases than in controls. Conclusion: In our study, the finger and palm print patterns show a statistically significant difference in certain parameters between patients with schizophrenia when compared with controls.

The Study On Correlation Of Dermatoglyphics And Schizophrenia

Background: Dermatoglyphics is the study of quantitative and qualitative patterns of ridges in palms and soles.It is being investigated in diseases having genetic basis. The recent evidence from adoption studies has provideda basis for the genetic contributions in schizophrenia. The present conducted to study the finger and palmardermatoglyphic patterns in schizophrenics and to compare dermatoglyphic configurations of schizophrenicswith the normal population.Materials and Methods: The ink and pad method was followed to take finger and the palm prints. The palmarprints of 50 schizophrenic patients and 50 normal individuals of both the sexes were collected for the study.Results: There is statistically significant decrease in frequency of arches in schizophrenics when compared tocontrols, whereas frequency distribution of radial loops, ulnar loops and whorls are not significant. Increase inI4 interdigital pattern is statistically significant in schizophrenics when compared to controls. There is increasein the mean values of total finger ridge count in male, female and combined series of male and femaleschizophrenics and decrease in absolute finger ridge count in male and combined series of male and femaleschizophrenics, while there is decrease in female schizophrenics, when compared to controls. Atd angle isdecreased in both the hands of male schizophrenics and right hand of female schizophrenics as compared tocontrols, whereas it is equal in the left hand of schizophrenics and controls. There is increase in the mean ridgecount in III, IV and V digits in the right hand of male schizophrenics.Conclusion: There are significant differences in the schizophrenics in various dermatoglyphic features, whencompared to controls. Hence it is possible to identify the ‘at risk’ population with the help of dermatoglyphics.

Assessment Of Digital Patterns In Carcinoma Breast Patients Of Madhya Pradesh

Background: Breast cancer is one of the most common cancer in females, it’s development has genetic basiswhich has been already established. Fingerprint patterns are also formed under genetic control early indevelopment almost at the same period during the development of mammary buds .They do not change significantlythereafter, and thus remains almost same whole life. So these patterns may be evaluated as a non-invasiveanatomical marker for breast cancer risk .Methodology: In this study assessment of the fingerprint patterns of both hands of 109 female breast cancerpatients were taken and compared with the patterns of 109 age matched normal healthy females.The Patternswere obtained by Ink method in an A4 size white paper. Fingerprints patterns (arches,loops and whorls) and totalfinger ridge count of both the groups was studied and analysed.Results: On statistical analysis it was observed that Whorl pattern are the significantly most common fingerprint pattern associated with breast cancer patients as compared to normal healthy females of Madhya Pradesh.Conclusion: The finger print patterns are significantly associated with carcinoma breast and in a developingcountry like India it may serve as an inexpensive and effective tool for screening the high-risk population forbreast cancer.
