Resumen El fútbol como disciplina ha sido objeto de numerosas investigaciones que han permitido la potenciación de las cualidades de las personas deportistas para alcanzar el máximo rendimiento deportivo. El uso de nuevas herramientas ha permitido mejorar los procesos de selección de talentos y el desarrollo de las capacidades físicas, como es el caso de la dermatoglifia, que brinda información del genotipo de un individuo. El presente estudio pretende relacionar la composición corporal, la dermatoglifia y el consumo máximo de oxígeno en jugadores de fútbol categoría sub 20. La investigación fue cuantitativa, diseño no experimental, de tipo transversal. La muestra estuvo conformada por 22 futbolistas (edad 18 ± 1.1) de un club deportivo de Bogotá, a ellos se les realizó una valoración de composición corporal, se les calculó el somatotipo, se analizaron las huellas de las manos y se midió el consumo máximo de oxígeno con el Test Course Navette. Los resultados muestran predominio del somatotipo mesomorfo balanceado (53%), alta presencia de presillas "L" (66.36%), baja presencia de arcos "A" (1.82%) y un consumo máximo de oxígeno de 53.76 ± 3.73 ml/kg/min. Además, se encontraron relaciones significativas entre componentes dermatoglíficos D10-SCTL y el somatotipo endomorfo (p < 0.05), y entre el VO₂ máximo con somatotipo endomorfo y ectomorfo (p < 0.05). Se concluye que los futbolistas se caracterizan por tener una predisposición hacia la coordinación, la resistencia y la agilidad.

Abstract Soccer has generated endless research that has enhanced athlete's qualities to achieve maximum sports performance. According to the above, the use of new tools has been implemented to improve talent selection processes and develop physical abilities, as is the case with dermatoglyphics that provides information on an individual's genotype. The present study aims to relate body composition, dermatoglyphics, and maximum oxygen consumption in soccer players' category sub-20. The research had a quantitative, non-experimental, cross-sectional design. The sample comprised 22 players (age 18±1.1) from Bogota Sports Club, Colombia. They were assessed for body composition, the somatotype was calculated, handprints were analyzed, and the maximum oxygen consumption was measured with the Test Course Navette. The results show a predominance of balanced mesomorph somatotype (53%), high presence of "L" ridges (66.36 %), low presence of "A" arches (1.82%), and maximum oxygen consumption of 53.76±3.73 ml/kg/min. Furthermore, significant relationships were found between D10-SCTL dermatoglyphic components and the endomorph somatotype (p <0.05), and between the maximum VO₂ with endomorph and ectomorph somatotype (p <0.05). It is concluded that soccer players are characterized by having a predisposition towards coordination, resistance, and agility.

Skin Carvings: Predictive Diagnosis in Modern Era.

The science and art of markings of the skin especially hands and feet’s is known as dermatoglyphics, where derma means skin and glyph mean carving. For centuries, the features of the hands have fascinated scholars, sages, theologians, doctors, and layman alike. In 1926 Cummins introduced the term “dermatoglyphics.” “Samudra Shastra” was known as ridge pattern study in ancient India. The epidermal ridge patterns were classified into “Chakra, Shankya, and Padma” which corresponds with the whorl, loop, and arch system of modern classification. All individuals have unique fingerprints which remain unchanged over the lifetime. Multiple genes determine fingerprint configurations and the study of fingerprints reveal vital genetic and medical information about an individual. Dermatoglyphics is considered as the window of congenital abnormalities and is a sensitive indicator of intrauterine anomalies. For preliminary investigations in conditions with a suspected genetic basis dermatoglyphic analysis is now beginning to prove itself as an extremely useful tool. In dentistry, various studies have been published on the dermatoglyphics. Here in this present review, the dermatoglyphic patterns of the palms and soles, the methods to record the palm and sole prints and various studies conducted among the dental disorders has been highlighted.

Prevalences of simian, Sydney and Suwon creases and their association with each other, body sides, handedness, sex and anomalies/diseases/syndromes in a population of Central India / Prevalencias de liegues simiesco, de Sydney y de Suwon y su asociación entre ellos, lados del cuerpo, dominancia manual, sexo y anomalías/enfermedades/síndromes en una población de la India Central

The Simian and Sydney creases are variant palmar creases which have now drawn medical attention as their presence correlates strongly with numerous chromosomal anomalies and diseases. Works on these creases have been done on several human communities, racial and ethnic but no specific study is focussed out on the Indian populations. In this study 1000 Central Indian subjects (500 males and 500 females) aged between 5 to 70 years were randomly selected and examined by the authors. We found the prevalence of Simian, Sydney and Suwon creases in studied population of Central India is 14.4 percent, 3.6 percent and 2.4 percent respectively, which is a little higher than the figures for Asians and Caucasians claimed by earlier studies. There is no any association between these creases. The Simian crease is predominantly unilateral right side and associated with handedness. It is more common in males. The Sydney crease does not have unilateral or bilateral predominance and association with handedness but it is more common in females. The Suwon crease does not have unilateral or bilateral predominance and association with handedness but it is more common in males. There is no association of these creases with anomalies/diseases/syndromes. Conclusively this work draws attention to the importance of undertaking parallel investigations on every socio-cultural human group or population wherever possible.

Los pliegues simiescos y de Sydney, son pliegues palmares variantes que en la actualidad han llamado la atención médica, ya que su presencia se relaciona estrechamente con numerosas anomalías cromosómicas y enfermedades. Investigaciones sobre estos pliegues se han realizado en diferentes comunidades humanas, raciales y étnicas, pero ningún estudio específico se centra sobre las poblaciones indígenas. En este estudio 1000 sujetos de la India central (500 hombres y mujeres 500) entre 5 y 70 años fueron seleccionados al azar y examinados. Se encontró que la prevalencia de los pliegues Simiescos, de Sydney y de Suwon de la población estudiada es de 14,4 por ciento, 3,6 por ciento y 2,4 por ciento respectivamente, mayor que los porcentajes en asiáticos y caucásicos. No hay ninguna asociación entre estos pliegues. El pliegue simiesco es predominantemente unilateral derecho y se asocia con dominancia manual. Es más común en los hombres. El pliegue de Sydney no tiene predominio unilateral o bilateral, ni asociación con dominancia manual, pero es más común en las mujeres. El pliegue de Suwon no tiene predominio unilateral o bilateral, ni asociación con dominancia manual, pero es más común en los hombres. No existe ninguna asociación de estos pliegues con anomalías/enfermedades/síndromes. Se concluye la importancia de realizar investigaciones paralelas en todos los grupos humanos o socio-culturales de la población siempre que sea posible.

Palmistry: A tool for dental caries prediction.

Background: Dermatoglyphics can prove to be an extremely useful tool for preliminary investigations in conditions with a suspected genetic base. Since caries is a multifactorial disease with the influence of genetic pattern, early prediction for high-risk children can help in using effective and efficient caries preventive measures that are a part of the pedodontist arsenal. Aims and Objectives: This study was done to determine the genetic aspect involved in the occurrence of dental caries through a cost-effective means, which can be used in field studies. Materials and Methods: 550 kindergarten school children in the age group 3-6 years were examined during a school examination camp. Of these, only 336 children were included in the study. They were divided into four groups as follows: caries-free males (df score=0), caries-free females, caries males (df score≥10), caries females. The handprints of each child were taken and the frequency of occurrence of type of dermatoglyphic pattern on fingertip of each digit was noted. Separate df scores were recorded. SPSS software and test of proportions were used for the analysis. Results and Conclusion: Handprints of caries-free children, especially females, showed maximum ulnar loops. The caries group showed maximum occurrence of whorls (r=2:1), which were more prevalent in females on the left hand 3rd digit than in males where the whorls were found on the right hand 3 rd digit, and also low total ridge count, especially in males.

Can dermatoglyphics be used as an anatomical marker in Egyptian rheumatoid patients?

To find out a possible correlation of some quantitative and qualitative dermatoglyphic variables with rheumatoid arthritis [RA] and it's radiological grading. This study was conducted on 60 RA patients and an equal number of controls. Different qualitative dermatoglyphic patterns [ulnar and radial loops, whorls and arches] and quantitative dermatoglyphic measures [total finger ridge count, pattern intensity and a-b ridge count] in addition to palmer creases were studied in both groups. Correlation between significant dermatoglyphic changes in RA patients and radiological changes were studied. Loops were the most common type of the qualitative dermatoglyphic patterns of the fingers, followed by whorls then arches. In both male and female patients, there was significant marked decrease in ulnar loops and increase in arches. Total ridge count and pattern intensity of patients were decreased in both hands of both sexes; however, this decrease was significant in the left hand of males and right hand of females. Moreover, the a-b ridge count was significantly decreased in both hands of female and left hand of male patients. Regarding the unusual palmer flexion creases, there was significant increase only in the Sydney line in female right hands. Significant inverse correlation was noted between total ridge count of the fingers and the radiological erosion in both males and females. Dermatoglyphics can represent an anatomical, non - invasive, inexpensive tool for screening high-risk population, and facilitate early detection and management of RA. Dermatoglyphic variable might also play a significant role not only for screening but also for studying the behavior of the disease

Perspective automated inkless fingerprinting imaging software for fingerprint research.

Fingerprint collection using ink-and-paper image is a conventional method i.e. an ink-print, transparent-adhesive tape techniques which are slower and cumbersome. This is a pilot research for software development aimed at imaging an automated, inkless fingerprint using a fingerprint sensor, a development kit of the IT WORKS Company Limited, PC camera, and printer The development of software was performed to connect with the fingerprint sensor for collection of fingerprint images and recorded into a hard disk. It was also developed to connect with the PC camera for recording a face image of persons' fingerprints or identification card images. These images had been appropriately arranged in a PDF file prior to printing. This software is able to scan ten fingerprints and store high-quality electronics fingertip images with rapid, large, and clear images without dirt of ink or carbon. This fingerprint technology is helpful in a potential application in public health and clinical medicine research.

Las impresiones digitales palmares, fueron realizados mediante el metodo de Hollister modificado y la clasificacion de los padrones de acuerdo a la sistematica propuesta por Penrose. Se efecturaon comparaciones intersexuales y comparaciones con otras etnias concurrentes del grupo. Se presentan los valores dermatoglificos del grupo mestizo fenotipicamente normales.

Dermatoglyphics in congenital profound sensorineural hearing loss: a disease marker?

A dermatoglyphic profile was carried out in 108 cases of congenital profound sensorineural hearing loss (SNHL) with delayed development of speech and language (DDSL). Rolled finger prints and palmar patterns were obtained by the ink method and analysed by the Galton system. In the genetic group (Group A) triradii 6 was present whereas it was absent in the nongenetic (Group B) group and their controls (p < 0.001). Loop pattern in interdigital areas did not vary significantly from controls. The average 'atd' angle in Group A was 41 degrees and that in the Group B was 46 degrees (p > 0.5). Ulnar loops predominated over the radial loops. Absence of CPW on thumbs of Group A was noted. Total ridge count in the Group A was 98.84 and 109 in the Group B (p < 0.05). It was observed that no definite pattern existed in a constant fashion and it also exhibited a great degree of variation, hence their role in detection of hearing loss is questionable.

Genetics of epidermal ridges: a study in subjects with refractive errors.

The dermatoglyphic characteristics of subjects with refractive errors when compared with control group revealed significant differences in both qualitative and quantitative parameters. The loops were increased in male myopics; the whorls were increased in male hypermetropics and astigmatics and the arches were decreased in all types of refractive errors in males. However, the whorls were decreased in female hypermetropics only. The mean total ridge count was significantly higher in male astigmatics only. As regards pattern intensity (fingers) no significant difference in the mean value was observed in either sex with any type of refractive errors when compared with those of controls.

Dermatoglifos mas frecuentes en el síndrome de Down: aplicación práctica / Dermatogliphies more frequent in the Down's syndrome: practice aplication

Se estudiaron los dermatoglifos palmares de cincuenta niños con Síndrome de Down y cincuenta niños normales, en edades comprendidas entre cinco y catorce años, con el fin de determinar su utilidad en el diagnóstico del Síndrome de Down. En base al anális de los resultados obtenidos se propone un método diagnóstico que toma en cuenta ocho parámetros y el cual, a diferencia de los hasta ahora propuestos, no requiere de complejas operaciones matematicas ni de largos procesos de computación. Con el se pretende hacer diagnóstico clínico temprano en aquellos casos donde existen algunos rasgos físicos sugerentes, sin pretender sustituir al estudio citogenético, que es el recurso que en definitiva dá el diagnóstico preciso

An evaluation of palmar flexion creases and dermatoglyphics in leprosy.

The palmar flexion creases and dermatoglyphics of 150 male leprosy patients (100 paucibacillary and 50 multibacillary leprosy) were compared with 50 matched controls. Among palmar dermatoglyphics a significantly high frequency (P less than 0.001) of palmar pattern in thenar/1st interdigital area was noticed on left palm of multibacillary leprosy patients. Slight increase in frequency of distal axial triradii (t' and t'') was also seen on palms of leprosy patients. No difference in values of atd angle and C-line types were observed between patients and controls. Among palmar flexion creases a significantly high frequency of Single Radial Base Crease (SRBC) and lower frequency of Double Radial Base Crease (DRBC) was noticed on palms of leprosy patients as compared to controls (P less than 0.001). The difference mainly exist on left palm. A significantly high frequency of Simian Crease was also observed on palms of multibacillary leprosy patients (P less than 0.001) and paucibacillary leprosy patients (P less than 0.05) as compared to controls.
