“…But the low intelligence group did have the most arch patterns as compared to the other levels of intelligence which does correlate with the study done on mentally retarded children. [9] A study was conducted by Dr. Lakshmi Kumari et al, on dermatoglyphics and intelligence of medical students and lab technicians with the assumption that the medical students are of higher intelligence due to clearing the competitive exams. A greater number of whorls were seen in most of the students perusing medical lab technician course than among the medical students pursuing MBBS in the same medical college.…”

BACKGROUND Dermatoglyphics is considered to be a window to a child's personal characteristics and a sensitive indicator of brain function abnormalities. Widespread interest in epidermal ridges is developing in the medical field. In this study, certain specific patterns were prominent in high, intermediate and low IQ groups which were characteristic of these groups. METHODS This cross-sectional study was conducted on 1000 school going children in the South Indian population. Hand prints were taken using the lipstick method. A modified version of the Wechsler PreSchool and Primary Scale of Intelligence was used to assess the intelligence of the students and they were accordingly grouped into high, intermediate, and low intelligence quotient groups. The hand prints from each of the intelligence groups were analysed thoroughly using standard parameters such as fingertip pattern, finger ridge count, palmar ridge count, and palmar angles. The results were tabulated and interpreted. RESULTS High intelligence levels showed the highest proportion of loops in all their digits. As the intelligence level decreased, the incidence of the arches and whorls increased. The thumb and 1 st digit especially showed these variations. The 4 th digit shows the highest incidence of loops in the high intelligence group with a number of 468, that is, 80.7% of loops. When taking the 1 st digit into consideration, the high intelligence quotient group showed 61.4% of loops, while the intermediate level shows just 54.5% of loops. The 1 st digit of the low intelligence level is the only one in the entire study to show more number of whorls than loops. Nearly half the patterns, that is 47.9%, were whorls in the low IQ group. The thumb also showed a higher number of whorl patterns and arch patterns with 36.6% and 20.6% respectively in low IQ group. In the low IQ level group, there is a significant difference between the total and absolute finger ridge count, indicating a greater prominence of whorl patterns. As the intelligence decreases, the difference between the total and absolute finger ridge counts increases, which correlates with the increase in the incidence of whorls. And finally, we found that the A-B ridge count increases as the intelligence decreases. CONCLUSIONS This study thus attempts to determine certain dermatoglyphic patterns in children of 4 to 7 years of age of varying intelligence quotient which may be extremely helpful in future studies by proving a basal patterning. It calls for further studies in the future to establish a definite relationship between intelligence and observed patterns.

Introduction- Etiology of mental retardation is multi-factorial which include various genetic and environmental factors. Minor physical anomalies are commonly observed in these children. Abnormal palmar creases are one of them. Aim-To compare prevalence of abnormal palmar creases in children with mental retardation and typically developing children. Methodology- Case controlled cross sectional study conducted on children with mental retardation and typically developing normal children. Photographs of palm were clicked using high resolution camera, digitally saved and evaluated later on. Results- The prevalence of abnormal palmar creases is increased in children with mental retardation. Correlation between increasing severity of mental retardation and abnormal palmar creases was noticed only in the right hand. Conclusion- Abnormal palmar creases are one of the minor physical anomalies found in children with mental retardation. Its presence would prompt clinicians for early screening and diagnosis which would increase possibility of early intervention.
