Study of Fingerprint Patterns among Young Adults and its Relation with Their Gender & Blood Groups

Fingerprint patterns are genotypically determined and remain unchanged from birth till death so they are used as effective means of establishing identity of an individual & study of finger prints as method of identification is known as Dactylography or Dactyloscopy. Aim- was to study fingerprint patterns among young adults & its relation with their gender & blood groups. Methods: Study includes 100 young adults of both genders selected randomly.Fingerprints were taken by pressing fingertips of subjects on stamp pad & then transferring the impressions on paper. Subjects were instructed to mention their Blood group, Age & sex on the same paper. Results: Subjects were having 69%,25%,6% of Loops, Whorls & Arches respectively.Males had 68%,26%,6% & females had 69%,24%,7% of Loops,Whorls & Arches respectively.Arches were absent in Rh -ve blood group & were maximum in blood group B+ i-e 50.8% followed by blood groups O+ve,AB+ve & A+ve with 34.4%, 13.1% & 1.7% respectively.Whorls were absent in B-ve Subjects & were maximum in B+vesubjects with 34.8% followed by O+ve, A+ve,AB+ve,O-ve,AB-ve with 28%,22.4%,10.8%, 2.4%,1.6% respectively.Loops were maximum in B+ve i-e 36.6% followed by A+ve,O+ve,AB+ve,O-ve,B-ve, AB-ve with 26.6%,24.5%,6.5%,3.5%, 1.4%,0.9% respectively. Conclusion: Loops are the most common & arches are the least common fingerprint pattern found in the population & Rh- blood groups lack Arches. whorls were absent in B-ve blood group & loops were minimum in AB-ve blood group.Whorls, loops & Arches all types were maximum in B+ve blood group.

Dermatoglyphic Pattern Differences in Females with Reproductive System Cancers and It’s Scope in Preventive Care

Introduction: Female reproductive system cancers shorten lifespan in women because of high mortality and morbidity. The detection of pre-invasive and micro-invasive stages makes near 100% survival of cancer patients. Dermatoglyphics is the scientific study of fingerprints. Many genes which take part in the control of finger and palm dermatoglyphic development distinguished cancer patients from the general population. It is possible that these genes also predispose to the development of malignancy. Since many investigations are needed to confirm the diagnosis of cancers, dermatoglyphics can be used as a screening procedure for planning preventive care if a specific pattern is known for a cancer. Aims and Objectives: To analyze the prints of different cancers, to analyze the results, compare with controls and observe the differences in main parameters of dermatoglyphic patterns and to determine a specific pattern for specific cancers. Subjects and Methods: This is a prospective, observational and an analytical study started after the approval by Institutional Ethical Committee of S.V. Medical College, Tirupati. The material for the study consisted of finger and palm prints of outpatients and inpatients of the Department of OBG, Tirupati, Cancer Hospital in and around Tirupati, Nellore and Kadapa. The ink prints of each finger and palm were collected and analyzed. Results: Ridge counts, digital patterns and main line formulae observed in different cancers in the present study were analyzed and presented. Mean TFRC was higher in normal group. Greater AFRC was observed in cancer cervix patients when compared to controls. In the present study, there is no difference (p> 0.05) in a-b ridge count among carcinoma of cervix and control group in both hands. Differences of mean atd, tad and tda angles among the groups are not statistically significant (P>0.05).The most common C-main line termination pattern of cancers are U followed by R and then Ab. IV interdigital area of both hands presented less incidence of loop pattern in cancer cases when compared to normal group. Special findings in respective cancers are discussed separately and they are not found in any other literature. Conclusion: There are very limited studies in literature on dermatoglyphic pattern in female reproductive cancers. Though the cost of prints is less, more time and skilled human resources are required for their analysis. Study sample size of controls and cases to be increased. Public should be enlightened about dermatoglyphics. If large number of studies are done and a specific pattern is established for specific cancers, then it becomes cost-effective to people so that a risk is predicted beforehand in any disease and preventive methods can be employed at an early age as the dermatoglyphic patterns do not change in a life time.

A Study of Sexual Dimorphism in Finger Print Pattern in Indian Population.

Background: In Dermatoglyphics the finger palms and soles elevation pattern are studied. The term dermatoglyphics, the uniqueness of a person’s fingerprints have been thought by some to be fixing to a person’s personality and constructing genetic quality of each individual. Methods: In the present study, 400 students are taken from out of which 200 males and 200 females. Prints are taken and the ridge counts are studied with the help of a magnifying lens. They are identified as: Arches, Loops and Whorls in both genders. The Performa is prepared on a durable A4 sheet divided into five marked areas. The right hand thumb (1) index finger (2) middle finger (3) ring finger (4) little finger (5), followed by the left hand; thumb (6) index finger (7) middle finger (8) ring finger (9), little finger (10). Result: The most common fingerprint patterns in Indian population is loops (both ulnar and radial) (60.65%) followed by whorls (34.7%) and arch (53.5%). The most common fingerprint patterns in Indian males is ulnar loops (55.1%) similarly (64.6%) females had ulnar loops. The percentage of whorls in males and females were 38% and 31.4% respectively. The rarest finger pattern was arch (6%) in males and (4.7%) in females. Conclusion: Dermatoglyphics can play an important role in person identity and gender estimation. Thus this study we prove helpful in forensic science and also in slowing medico legal cases.

A Study to Find Correlation Between Dermatoglyphic Patterns and ABO Blood Groups.

Background: Dermatoglyphics, the study of fingerprints are constant and individualistic. It has been found useful in forensic medicine and identification purpose. It is useful in medical diagnosis of genetically inherited diseases and in detection of crimes. Objectives: The present study was conducted to correlate between digital dermatoglyphics patterns in ABO, Rh blood groups and to evaluate their significance. Methods: A total of 200 first year MBBS students of Pt. B.D. Sharma PGIMS, Rohtak, India, with known blood groups from age group 17-22 yrs were included in the study. Fingerprints were obtained by Ink method. Parameters studied were arches, whorls, loops. Results: Majority of the subjects (43.5%) in the study were of blood group A followed by blood group O, A and AB of whom 94.5% were Rh-positive. The general distribution of pattern of finger print showed high frequency (51.87%) of loops followed by whorls and arches. Almost same order was noticed in both Rh-positive and Rhnegative individuals or A, B, AB and O blood groups, except blood group O-ve which showed more whorls. Conclusion: There is an association between distribution of finger print pattern and blood groups.

Qualitative palmar dermatoglyphic patterns in cases of idiopathic generalized epilepsy.

Background: Genetic etiology has been proposed for both idiopathic epilepsy and dermatoglyphics. Hence, the present study has been undertaken to find out the existence of any correlation between dermatoglyphics and idiopathic generalized epilepsy. Objective of current study was to find out an association, if any, between dermatoglyphic patterns of hands in idiopathic generalized epilepsy of both sexes. Methods: The study was conducted in the department of anatomy and department of neurology, Himalayan institute of medical sciences, Swami Ram Nagar, Dehradun. Fingertip patterns (whorls, loops, arches) and Main line (A, B, C, D) terminations were analysed by utilizing finger and palmar prints. Results: The present study showed a significant decrease in whorls and an increase in arches in both the hands of male and female IGE patients. Loops were increased in both hands of female patients. Main line D was mostly confined to sectors 11, 9 and 7 in both sexes among the cases and controls. Main line C terminated quite often in sectors 9 & 7 in males and females of the case series. Main line B terminated most frequently in sectors 5'' & 7 in control and case groups. Main line A terminated most frequently in sector 5' in males and females. Conclusion: Therefore, we can conclude and hypothesize merely by observing decrease in the whorl and increase in the arch patterns in the fingerprints (as observed in the present study) that persons with high risk of idiopathic generalized epilepsy can be identified early and preventive measures can be taken against serious complications.

Utility of dermatoglyphics as a non-invasive diagnostic tool inrecurrent aphthous stomatitis / Utilidade da dermatoglifia como ferramenta diagnóstica não invasivapara estomatite aftosa recorrente

Introduction: Dermatoglyphics is an advancing branch of medical science in which the dermal ridge patterns are studied and used in prediction of genetic disorders. Objective: To assess the usefulness of dermatoglyphics, as a non-invasive early predicator in RAS, since genetics plays a role in both. Materials and methods: This case control study comprised of 40 patients with recurrent aphthous stomatitis compared to 30 control subjects of similar age and sex. All subjects were investigated for their dermatoglyphic patterns of both hands, which were obtained by smearing the ink uniformly over the palm and fingers and pressing the hands firmly against the good quality paper. Qualitative analysis of prints was done for arches, loops and whorls and quantitative analysis included Total Finger Ridge Count (TFRC) and atd angle. Fisher’s Exact Tests were used to evaluate the significance between recurrent aphthous stomatitis and the dermatoglyphic features. Results: Among various dermatoglyphic parameters analyzed, recurrent aphthous stomatitis patients showed 9% arches, 62% loops and 29% whorls as the finger ridge configuration. In comparing the results between the two groups, the frequency of arches was observed more in study group while composite whorl and the nar pattern were more frequent in control group, the results were statistically significant (p < 0.05). In addition to this, study group patients demonstrated higher frequency of total finger ridge count, and control group showed higher frequency for atd angle on both hands, statistically significant difference is observed (p < 0.05). Conclusion: The study found significant correlation between palmar dermatoglyphics and recurrent aphthous stomatitis, suggesting that genetics is one of the host risk factor associated with the latter, and could aid in early detection of the disease.

Introdução: Dermatoglifia é um avançado ramo da ciência médica em que os padrões de cristas dérmicas são estudados e utilizados para predizer distúrbios genéticos. Objetivo: Avaliar a utilidade da dermatoglifia, como método de diagnóstico não invasivo para a estomatite aftosa recorrente, uma vez que a genética desempenha um papel em ambos. Materiais e métodos: Estudo caso-controle composto por 40 pacientes com estomatite aftosa recorrente comparados a 30 controles de mesma idade e sexo. Todos os sujeitos foram avaliados quanto a seus padrões dermatóglifos de ambas as mãos. Os padrões dermatóglifos foram obtidos espalhando uniformemente uma tinta sobre a palma da mão e os dedos e pressionada firmemente contra um papel de boa qualidade. A análise qualitativa das impressões foi feita por arcos, laços e espirais e a análise quantitativa pela contagem total da polpa do dedo (TFRC) e ângulo atd. Teste de Fischer foi utilizado para avaliar a significância entre estomatites recorrentes e características dermatoglíficas. Resultados: Entre os vários parâmetros dermatoglíficos analisados, os pacientes com estomatite aftosa recorrente mostraram 9% de arcos, 62% de laços e 29% de espirais na configuração da polpa digital. Ao comparar os resultados entre os dois grupos, a frequência de arcos foi mais observada no grupo de estudo, enquanto verticilos e padrão tênar foram mais frequentes no grupo controle, com resultados estatisticamente significativos (p < 0,05). Além disso, os pacientes do grupo de estudo demonstraram maior frequência de contagem total da polpa digital e o grupo controle apresentou maior frequência para o ângulo atd em ambas as mãos, com diferenças estatisticamente significativas (p < 0,05). Conclusão: O estudo encontrou correlação significativa entre a dermatoglifia palmar e estomatites recorrentes, sugerindo que a genética é um dos fatores de risco de hospedeiro associado com estomatite aftosa recorrente, e poderia ajudar na detecção precoce da doença.

Liposarcoma with Meningothelial-like Whorls. Report of Four Cases Showing Diverse Histologic Findings and Behavior

We report the clinicopathologic findings of four cases of liposarcoma with meningothelial-like whorls. Two cases occurred in the retroperitoneum and the remaining cases in the anterior mediastinum and scrotum. The whorls varied in terms of amount and morphology and the type tissue surrounding the whorls also varied in every case. One of the retroperitoneal cases with large areas of whorl coalescence recurred in the abdominal wall as an inflammatory malignant fibrous histiocytoma one year after primary resection of the tumor, and a metastasis to the cervical spines was detected twenty months later. The other retroperitoneal tumor recurred locally two years after the resection of the tumor and the amount and cellularity of the whorls as well as p53 reactivity and Ki-67 labeling index were higher in the recurrent tumor. However, coalescence of the whorls was not present in the recurrent tumor in contrast to the primary tumor. The anterior mediastinal and scrotal cases have demonstrated neither local recurrence nor distant metastasis although the follow-up period has been less than one year. The cells comprising whorls showed positive reactions for CD10, CD56, CD99, factor XIII, and low-affinity nerve growth factor receptor in addition to vimentin and alpha-smooth muscle actin. Our results indicate that liposarcoma with meningothelial-like whorls is a heterogeneous group that shows wide variations in histologic findings and biologic behavior. The phenotypic transformation of the whorls to higher grade in two retroperitoneal tumors, which showed recurrence within two years of follow up, supports that a whorl is a sign of dedifferentiation. Although we demonstrate the expressions of several markers, such as CD10, CD56, CD99, factor XIII, and low-affinity nerve growth factor receptor, in the spindle cells of the whorls for the first time, the lineage of the whorls still cannot be addressed due to the fact that these markers are lineage nonspecific.
