Introduction: Cephalic index is the percentage of head breadth to head length. The index is calculated from measurement of the diameters of head (head length and head breadth). When applied to living individuals it is known as cephalic index, and when referring to dry skulls, the cranial index. This index is used as a useful anthropological tool for analysis of racial and sexual differences in a population. The present study was done to find out Cephalic Index and to study sexual dimorphism in adult North Indian population. Objective of the study was to calculate the cephalic index and to find out that the present study group belongs to which category in the classification of skull based on cephalic index and to study the sexual dimorphism in respect to cephalic index. Material & Methods: The present study comprised of 200 medical students of age group between 18 yrs. to 25 yrs. of S.N. Medical College, Agra, not having any significant disease or deformity that could have affected the general or the bony growth. Two anthropometric parameters; head length and head breadth were recorded in centimeters by using spreading caliper. With these recorded data, cephalic index was calculated for males and females separately as well as combined. Results: Mean Cephalic Index was significantly higher (p=0.03124) in females (79.350 ± 5.7157) as compared to males (77.715 ± 4.9102). Conclusion: There was a statistically significant difference in the mean of the cephalic indices of male and female students (p=0.03124). The mean cephalic index of combined population in this study was 78.533 ± 5.3776 which states that the dominant head shape among North Indians is Mesaticephalic.

Background Cephalic index (CI) is one of the important anthropometric parameters to determine racial variation.  Studies done in Nepal has made a comparison of cephalic index for castes (Tharu, Brahmin, Chhetri, Newar), races (Mongoloids and Aryans) but lacks sex variation. The objective of this study was to find the difference in the cephalic index between two genders and to find the sequence of most predominant to least common head type in different genders among the Medical Students of Birat Medical College & Teaching Hospital (BMCTH). Methods A cross-sectional study conducted in the department of Anatomy of BMCTH from 1 July 2019 to 1 September 2019 comprising of 256 medical students (133 male and 123 female) aged between 18 to 24 years. Head length, head breadth and cephalic index were the variables measured using standard devices and techniques. Ethical clearance was taken from the Institutional Review Committee (IRC) of Birat Medical College & Teaching Hospital, Nepal. Results The mean cephalic index in male and female is found to be 81.41 ± 4.52 and 83.62 ± 4.08 respectively. Statistically significant difference found between gender in terms of head length males (18.78±0.69) and females (17.71 ± 0.60); head breadth males (15.28 ±0.62) and females (14.79 ±0.57). The mean cephalic index in males is 81.41 ± 4.52 varying from 69.31 to 94.48. In females, the cephalic index varied from 74.74 to 93.14 and the mean cephalic index is 83.62 ± 4.08. The difference between male and female cephalic index is found to be statistically significant. Majority (43.75%) had Brachycephalic head (CI>79.9) followed by Hyperbrachycephalic (26.95%), Mesocephalic (25.39%), and Dolicocephalic (3.90%). Conclusion Cephalic index is significantly high in female as compared to male whereas head length and breadth are significantly high in males than females. It confirms sexual dimorphism exists. Brachycephalic is the commonest head type.

Cephalic index is an important parameter in evaluating racial and sexual differences, is measured by establishing a ratio between the breadth and the length of the head calculated as 100 times the maximum breadth of the head measured at the greatest diameter of the cranial vault above the supramastoid crest divided by the maximum length of the head measured from the most prominent point on the glabella to the opisthocranion. The aim of the research was to differentiate the cephalic index between female Indian and Chinese Malaysian studying in Padjadjaran University. This research was a descriptive study with total samples are 35 comprise of 13 females Indian and 22 females Chinese. The sampling technique used was stratified random sampling. The subjects were measured for head length and head breadth by using a spreading caliper. The result of the research shows that 22 female Chinese surveyed has an average cephalic index of 85.861(hyperbrachycephalic) with a standard deviation of 3.717. Meanwhile, the 13 female Indian surveyed has an average of 81.768 (brachycephalic), with a standard deviation of 3.205. The conclusion of this research is that there is a significant difference of cephalic index between females Indian and Chinese Malaysian.

Background: The third trochanter is an osseous-cartilaginous-tendinous complex. It is a term used for a prominent oval structure usually confined under the greater trochanter in the superior end of gluteal tuberosity. The third trochanter results from increased pull of the gluteus maximus. The third trochanter gives the muscle better grip, helps to alter the direction of tendon and improves effective function. Purpose of the study: The present study was undertaken to compare the incidence of the third trochanter in human femora with other series and to correlate with its morphometry. Materials and Methods: 56 dry human femurs (28 each of right and left side) of unknown age and sex were obtained from fellow undergraduate students at ESIC Medical College and PGIMSR, Bangalore, Karnataka, India. Trochanters with damaged upper ends were excluded from the study. After careful examination two femurs were excluded and the rest were subjected to identification of third trochanter. Results: The incidence of the third trochanter in the present study was 14.28% with the right side predominant (10.71%). The mean length and width were 17.87mm and 7mm respectively. The femurs with the third trochanter were found to have better developed greater trochanter and all the osteometric measurements were found to be higher compared to the ones without. No significant difference was noted in the morphometric indices, as all the osteometric measurements were uniformly increased. Conclusion: This study was performed to increase the understanding of this post-cranial non metric trait on Indian population because of scarcity of information on this variation of human femora. We find the incidence more on the right side indicative of dominant side in most people. The femurs were uniformly bulkier as seen in better built human femurs. Hence, it is a change to meet the functional demands. KEY WORDS: third trochanter, trochanter, femur, morphometry, gluteus maximus, bony projection, non-metric variant, post-cranial.

BACKGROUND Femur is the longest and strongest bone of the human body. It also takes relatively longer time to disintegrate after death, hence morphometric analysis of skeletal remains of femoral head can be considered for the determination of age and sex for forensic expert, anthropologist as well as anatomist. The present study was an attempt to establish sex of a skeleton by the help of femoral head diameters which will be of great help in medico-legal and anthropometric studies. METHODS The present study was carried out in the S C B Medical College Cuttack from May 2019 to June 2020 by taking 84 dried and intact femora. The vertical head diameter of femoral head and head circumference were measured by the vernier’ s caliper and measuring tape in centimeters. RESULTS The result showed significant difference in the head circumference and the vertical diameter of head of femur of the male and female femora. It was found that the mean femoral head circumference of the male was 13.296 cm with a “S.D” of 0.8694 cm and female was 12.023 cm with a “S.D” of 0.73 cm and vertical diameter of male was 4.1520 cm with a “SD” of 0.3635 cm and that of female femora was 3.7231 cm with a “S.D” of 0.2264 cm respectively. CONCLUSIONS There was a significant difference in the head circumference and the vertical diameter of head of femur of the male and female femora which determines sexual dimorphism.

Background and objectives: Identification, an aspect of forensic anthropology, is the recognition of an individual based on the physical characteristics unique to the individual. Among the four main attributes i.e. gender, age, stature and ethnic or racial background of an individual’s biological identity, sex determination is usually the first step in the human identification process. Teeth can be used as a means of sex determination as teeth are resistant to post-mortem degradation and survive deliberate, accidental or natural change. This study was carried out with an objective to determine the sexual dimorphism of maxillary and mandibular canine by linear tooth diameter for permanent dentition in Moradabad population. Material and Methods: A total number of 40 subjects (20 Males and 20 Females) were included in this study. After obtaining an informed written consent, alginate impression was taken with help of perforated impression trays and study models were prepared with type IV dental stone. Linear (MD, BL, Crown Height) were taken with digital vernier caliper. Results: It was observed that males’ shows more mean linear crown diameter as compared to females. Also, the mesiodistal and buccolingual measurement shows statistically significant difference for all canines, being higher for males than females. Conclusion: The present study has expressed sexual dimorphism of permanent canine using Student’s test and indicate that linear dimension of maxillary canine can be used for sexual diamorphism with accuracy along with other accepted procedure for sex determination.

Introduction: The aim of this study was to evaluate the role of Thr715Pro P-Selectin gene polymorphism in patients with Diabetic Retinopathy in North Indian population and establish its role in the pathophysiology as an independent factor. Materials and methods: This is a prospective clinical study conducted on 60 patients at a tertiary care centre in North India over a period of eighteen months. Sixty patients satisfying the inclusion criteria were selected from the Vitreoretina clinic in the department. They were categorised equally in three groups namely Diabetics with diabetic retinopathy (DwDR), Diabetics without diabetic retinopathy (DwoDR), and non diabetics. The non-diabetics group was further divided into healthy controls, Hypertensive Retinopathy (HR) and Non-exudative Age Related Macular Degeneration (NEAMD). All the patients underwent complete ophthalmic evaluation and blood samples were drawn for the genetic study with their informed consent. Data was analysed using SPSS software version 16. Results: The genotypic analysis between DwDR, DwoDR and the three subgroup of controls comprising of healthy controls, HR and NEAMD showed that Thr715Pro (A/C) polymorphism prevalence was significantly high in DwDR (p = 0.003) and DwoDR (p = 0.003) compared to healthy controls. No significant difference was noted between DwDR, DwoDR and the HR and NEAMD groups.  Conclusion: Thr715Pro P-Selectin gene Polymorphism could not be established as an independent factor in the pathogenesis of diabetic retinopathy, as its association is found with other systemic diseases which create a prothrombotic state.
