Sex variations in thumbprint ridge count of a Nigerian population in Calabar Municipality

The present study aimed at determining the association between thumbprint ridge count and sex variation among Nigerians in Calabar Municipality. A total number of 300 subjects (150 males and 150 females) aged between 12-35 years participated in the study. Conventional method of using ink pad was used to collect thumbprint of both hands and analysed using magnifying lens. The study confirmed the results of some earlier works done by other researchers on fingerprints. It further established the distribution proportions of thumbprint for both hands in both sexes for the population. The uniqueness of fingerprint to individuals was reaffirmed as no two thumbprints were identical among the 300 subjects under study. These results show that the order of prevalence are as follows; among males, in whatever combination of thumbprint pattern, whorl is the most occurring, followed by loop and arch. Among females, in whatever combination of thumbprint pattern, loop is the most occurring followed by whorl and arch. The result equally showed the mean thumbprint ridge count of females to be lower than that of males (20.91 as against 27.85 respectively). The difference in pattern between left and right hands in females was significant. In conclusion the thumbprint ridge count shows gender dysmorphism in the Nigerian population.Keywords: Fingers, epidermal ridges, thumbprint ridge coun

Dermatoglyphic appraisal of multiple births women in Igbo-Ora and Ogbomosho, South west, Nigeria

The scientific study of epidermal ridges on the palms and toes is termed dermatoglyphics. Multiple births occur when more than one fetus results  from a single pregnancy. This study is aimed at determining the relationship if any between multiple births and palmar flexion creases. Two  hundred Igbo-Ora and one hundred Ogbomosho healthy and consenting adult female indigenes aged between 25-50 years were recruited and grouped into 4; group I consisted of multiple births women in Igbo-Ora; group II consisted of single births women in Igbo-Ora; group III consisted of multiple births women in Ogbomosho; and group IV consisted of single births women in Ogbomosho. A total of 600 palms (Igbo-Ora n=400; Ogbomosho n=200) comprising of both hands were used in the study. Palm prints samples were obtained by asking the participants to wash their hands, towel dry them, after which they were stained with stamp ink pad and prints made on A4 paper in duplicates. Palm print patterns of 105 (Igbo-Ora) and 50 (Ogbomosho) women with multiple births were compared with 95 (Igbo-Ora) and 50 (Ogbomosho) women with single births. The percentage number of primary, P and intersection, I of palmar creases with complete transverse creases, C (PIC) 300 bilaterally was significantly  greater (p < 0.005) in the hands of Igbo-Ora multiple births women (52.4 %) than their single births women (37.4%) while same trend was observed for Ogbomosho women although difference was statistically insignificant,(p > 0.005). In both Igbo-Ora and Ogbomosho women, PIC 310 bilaterally was found to be significantly higher (p < 0.05) in both hands of single births women than the multiple births women. Hence, dermatoglyphics can be said to have relationship with a woman’s tendency to giving birth to multiples. Keywords: Multiple births, dermatoglyphics, palmar flexion creases, Ogbomosho, Igbo-Or

Dermatoglyphics in common: genetic disorders and cancers

This review article offers information to deal with fingerprints within the most prevalent genetic disorders and cancers. Dermatoglyphic refers to the formation of present ridges in some body parts like fingers, palm, soles, and toes; these ridges unchanged throughout life. There are three sorts of fingerprint patterns: Arches, loops, and whorls. The most pattern of dermatoglyphics is related to genetic disorders as in Down syndrome and Klinefelter's syndrome and applied in medicinal studies and also useful within the diagnosis of the many genetic disorders and a few sorts of cancers. Ridge count one among the foremost important parameters which will be advantaged for determine some genetic disorder and cancers like thalassemia, carcinoma, thyroid, and cervical cancers, but there are controversial from studies to studies not confirmed altogether research. Another parameter could also be differences in some sorts of cancers and statistically significant, for instance in early diagnosis of prostate cancer. DOI: http://dx.doi.org/10.5281/zenodo.399647

Monozygotic and Dizygotic Twins Differences in Fingerprint Patterns of Swat District

Background: The identification of individual is important for both legal and humanitarian reasons. It is of great importance because every individual exists as an entity in a society and is dealt with as such by the legal system. The most commonly used method for identification is fingerprinting which relies on the uniqueness of ridges present on thumbs and fingers. These are unique in arrangements and remain constant throughout an individual’s life. Fingerprints of no two individuals are same even if they are twins. The power of discrimination of the basis of fingerprinting is about one in 64 billion. The study was designed to carry out analysis of fingerprints from mono and dizygotic twins and to differentiate them on the basis of fingerprinting.Methods: This was a prospective cross-sectional study carried out among 30 pairs of twins including 17 pair of monozygotic twins and 13 pair of dizygotic twins. After taking an informed expressed consent, the participants were asked to press their individual fingers on the stamp pad. They were asked to then put and roll the stamped finger onto an A4 size paper on which blocks for each finger were already made. Both left and right hands were fingerprinted and with the help of magnifying glass, different types were identified including Arches, Composite type, Loops and Whorls. SPSS software was used for data analysis.Results: There was 7.6% of Arch type, 6.1% of tented arches, 1.5% of plain arches, 62.32% of loops, 6.66% of double loop, and 3.83% of central pocket loop, 44.83% of ulnar loop, 7% of radial loop, 0.83% of accidental loop, 29.93% of whorls, 9% of plain whorl and 20.1% of central the pocket whorl.Conclusion: When the left and right thumbs are compared with each other using eight (8) points, there are matches on the first six (6) points, matching percentage for each of these pairs of fingers is 75%. But when the both fingers were rotated on 180° and compared, the matching percentage was 87.5%. These 8 points fingerprinting can be used to distinguish twins.Keywords: Fingerprint; Identification; Twin; Monozygotic; Dizygotic

Dermatoglyphic patterns in type 2 diabetes mellitus

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 they persist throughout life unless there is damage to the dermis. The patterns of fingertip patterns begin to form around the 13th week of intrauterine life. These patterns are inherited in from genetic makeup of the parents but the inheritance is not purely Mendelian. They get modified during the first few weeks of the intrauterine life due to pressure on the finger pads and on the palms.Keywords: Epidermal, Dermatoglyphics, Genetic, Arche

Correlation between Dermatoglyphics, Dental Caries and Salivary pH: An Invivo Study

BACKGROUND: Dermatoglyphic patterns that are often utilized in judicial and legal investigations are valuable in diagnosis of many diseases related to genetic disorders. Caries, being infectious in origin, might be related to genetics as well. Hence, these patterns are of significance in predicting caries development.MATERIALS AND METHODS: DMFT (decayed, missing, filled teeth) score of 300 female subjects within the age group 0f 18-25 years were recorded and accordingly divided into 3 groups of 100 each; group 1 (DMFT score=0), group 2 (DMFT score < 5) and group 3 (DMFT score ≥ 5). Dermatoglyphic patterns were recorded using Cummins and Midlo method. pH meter was used for recording salivary pH accurately. Fingerprint patterns and salivary pH recorded were correlated with DMFT scores of subject and control groups. Statistical analysis was performed using ANOVA and Chi-square tests (P < 0.05).RESULTS: The mean salivary pH was least in group 3. The predominant dermatoglyphic pattern observed in groups 1 and 2 was loop pattern whereas, in group 3, whorl pattern was predominant. The TFRC (total finger ridge count) was higher in group 3 compared to the other two groups.CONCLUSION: Caries-free people showed inflated frequency of loops, whereas subjects with high decay score had additional share of whorls. The TFRC was higher in individuals with high DMFT score, and salivary pH was inversely proportional to the DMFT score.
