Study on Branching Pattern of Arch of Aorta in South Indian Population.

Background and aim:Arch of aorta is the continuation of ascending aorta lies in the superiormediastinum. The present study aims at finding the branching pattern of arch of aorta and correlate it with the embroyological and clinical significance. Materials andMethods: 30 formalin-fixed cadavers procured fromthe department of anatomy, Karpaga Vinayaga Institute ofMedical Sciences,Madhuranthagamwere dissected to study the branching pattern of arch of aorta. Results:Out of 30 cadavers 19 cadaversNormal branching pattern (Right brachiocephalic, Left common carotid and Left subclavian artery).10 cadavers showed the left common carotid arising in common with the brachiocephalic trunk. Only one showed the left vertebral artery arising directly from the aorta, the origin lying between left carotid and left subclavian arteries. Conclusion: Knowledge of normal anatomy and frequency in the variations in the branching pattern of the arch of aorta is of great importance in patients who have to undergo aortic instrumentation, four vessel angiography or supraaortic thoracic, head and neck surgery.

Study of palmar patterns in diabetic patients.

Nowadays study of dermatoglyphics has a great importance in judicial and criminal researches. Similarly its study is related to some genetic diseases has an immense applications. Diabetes Mellitus is the silent killer of mankind and public health problem. Therefore investigators are looking for new methods for its early diagnosis and treatment. Dermatoglyphics is a growing discipline and its ease and ready applicability render it as a useful tool to the clinician. Dermatoglyphics may be effectively employed as a screening procedure in future and may help in the early detection of cases of diabetes mellitus. Methods: The present study is undertaken with an aim to evaluate the dermatoglyphic features in diabetic patients. The study consists of 150 diabetic patients and 150 normal healthy individuals as controls. They were 75 males and 75 females in each group. Dermatoglyphic prints were taken by “Ink method” described by Cummins and Midlo and further subjected to statistical analysis to find the variations in the dermatoglyphic features among diabetic patients and control groups. Results: Mean value of a-b ridge count is neither increased nor decreased in diabetic patients (P = 0.852). Mean value of atd angle is slightly decreased in diabetic patients (P = 0.2332). The frequency of t and t' are increased (P = 0.8462, P = 0.6681) and the frequency of t" is decreased (P = 0.757) in diabetic patients but they are not statistically significant. Conclusion: From the present study, it appears that there do exists a variation in the dermatoglyphic patterns in diabetic patients with an advantage of being simple and economical ‘ink’ method. As the specific features of dermatoglyphic patterns are present in diabetic patients, it can be used for mass screening program to segregate the predicted diabetic patients.
