An anatomical study of medial epicondyle in relation with nerves

Background: Cubital tunnel syndrome, or ulnar nerve compression at the elbow, is the second most common compression neuropathy after carpal tunnel syndrome. Aims and Objectives: To study anatomy of the medial epicondyle in relation with nerves. Methodology: This was a cadaveric study in the 36 cadaveric hand dissected in the department of anatomy of V D Government Medical College, Latur during the two year duration i.e. January 2019 to January 2021, in the 2 years duration all the cadavers are dissected carefully and the observations were noted in the excel sheet. Data was entered in the Microsoft excel for windows 10 software and calculated Mean and Standard deviation. Result: In our study, Arm length (cm) was 28.12 ± 2.34; Length of Arcade of Struthers (AS) (cm) was 4.12 ± 1.65 Distance between AS and Medial epicondyle was 8.62 ± 0.98. Average branching pattern of nerve related to medial epicondyle i.e. for Median nerve branching (Mean ±SD) - 3.1 ± 0.94; Radial nerve branching (Mean ±SD) -2.28 ± 1.02; Ulnar nerve branching (Mean ±SD)- 2.91 ± 0.59 respectively. Conclusion: An anatomical study of medial epicondyle in relation with nerves not only important for the prevention of pathologies of elbow but also helpful in the treatment of the fractures of lower end of humerus and medical epicondyle.

Study of quadrifurcation of left coronary artery and its clinical importance

Background: The aim of this study is to study the incidence of quadrifurcation of coronary artery in 76 adult human hearts using dissection method. The incidence of quadrifurcation of left coronary artery in our study is 4%. This study would be significant for proper interpretation of coronary angiographies, proper management of patient undergoing percutaneous coronary intervention as well as surgical myocardium revascularization. As coronary artery disease is one of the major cause of death in developing countries. The knowledge and incidence of such coronary artery patterns will be useful in diagnostic and therapeutic interventional procedures.

A study to estimate the cranial capacity in 100 dry human skull bones

Background: Craniometry is the scientific measurement of the skull useful for anthropometry and forensic practice. Cranial index variations between and within population have been attributed to a complex interaction between genetic and environmental factors. The morphometric and non-morphometric studies of human skulls are very helpful for identification of the sex and age by anthropologist and forensic practice. Cranial dimensions and Cranial indices are considered as simplest and most efficient way to indicate facial differences. Materials and Methods: The present study will constitute 100 dried adult skulls belonging to both sexes available in the department of anatomy and forensic medicine RRMC and H, MS Ramaiah medical college and Sapthagiri medical college, Bangalore. Results: The mean cranial index of the skulls were 76.989 which classifies them under mesocephalic type and we find a significant correlation between the cranial index and the length height and breadth height index with the p value coming below 0.001. Conclusion: The mean, SD of all the parameters to calculate is mentioned in table 1. The mean cranial index is 76.989 with the standard deviation of 5.8775, that of length height index was 76.991 with SD of 4.4615 And that of breadth height index was 100.268 with SD of 5.4350. There is a significant correlation between the cranial index, the length height and breadth height indices. With a correlation value of 0.681 for length height index and -0.635 for breadth height index. Both had a p value <0.001.

Assessment of DNA damage through micronucleus studies in subjects exposed to formalin

Background: Formaldehyde (FA) is the reactive and simplest of all the aldehydes. It is used as a preservative in anatomy, pathology and forensic laboratories. The international agency for research on cancer has classified FA as a carcinogen that can cause nasopharyngeal carcinoma, Leukaemia, Liver and pancreatic cancer. Objective And Method: The aim of the study was to assess the DNA damage in peripheral blood lymphocytes and in buccal cells by Micronucleus assay in Formalin exposed workers of Anatomy, Pathology and Forensic laboratories and compare with the control group, and also to analyze the relationship between frequency of Micronuclei and duration of exposure to formalin. Results: The mean and standard deviation (SD) of micronuclei in peripheral blood of exposed was 8.35 and in controls was 4.18. There was a significant increase in the frequency of MN in exposed group when compared with the comparison group (p<0. 5876). Pearson’s correlation test showed a positive correlation between the years of FA exposure and the number of micronuclei in buccal cells and peripheral blood indicating that DNA damage due to FA was directly proportional to the duration of exposure (r=0.8, 0.9). Conclusion: The present study was done to assess the DNA damage in people who were exposed to FA and a control group not exposed to FA by buccal cell and peripheral blood Micronucleus Assay. There was a significant increase in the MN in people exposed to FA which was directly proportional to the duration of exposure.

Study on variations in hilar and segmental branching pattern of splenic artery

Background: Introduction of laparoscopic surgical methods requires exact knowledge of the topography of the spleen and its surrounding. Further advances in splenic conservative surgery are dependent on better knowledge of vascular anatomy of the spleen. Hence segmental arteries of spleen are of great surgical importance and their early identification in splenic trauma will lead to enhanced splenic conservation. Materials and methods: Present study carried out on 50 human spleen by dissection, silicon injection and radiological methods. We found different types of variations in hilar and segmental branching pattern of splenic artery. Observations and Results: in present study splenic artery divided in two primary branches in 86% and in three primary branches in14% of the spleens. superior polar branches were found in 44% while inferior polar branches were in 52% of the spleens. Two segmental branches found in 24%, three segmental found in 50%, four segmental in 18% and five segmental in 8% of the specimens. Intersegmental anastomosis found in 2% of spleens. Discussion: These segmental resection of spleen and further advances in splenic conservation are dependant on better understanding of vascular anatomy of the spleen.
