    Bifurcation Levels of The Common Carotid Arteries: A Cadaveric Study in South Indian Population.
    (2014-07) Radha, K
    Background and aim: The present study aims at finding the bifurcation level of common carotid artery and correlate it with the level of upper border of thyroid cartilage. Materials and Methods: Forty cadavers were dissected to study the bifurcation level of common carotid artery. The symmetry between the sides were noted. Results: The level of bifurcation of the common carotid artery was at the level of upper border of thyroid cartilage in sixty-seven cases .Only nine cases showed the higher level with the range of 3.2 mm to 19.3 mm above the level of upper border of thyroid cartilage.4 cases showed the lower level of bifurcation in the range of 2 mm to 10 mm below the level of upper border of thyroid cartilage. In the present study, the bifurcation levels were symmetrical on both sides. Conclusion: The bifurcation level of common carotid artery coincides with the upper border of thyroid cartilage in the present study. The awareness in the variation of bifurcation level is necessary to avoid undue complications during the surgeries and procedures done in head and neck region.

    Fissures and Lobes of Lungs: A Morphological and Anatomical Study.
    (2015-04) Radha, K; Durai, Pandian K
    Background and Aims: The fissures of the lungs serve as boundaries for the lobes of the lungs. They also acts as barriers to avoid the spread of pathologies .The proposed aim of the study was to study the fissures and lobes of the lungs and their variations and to compare them with previous studies and to find their clinical implications. Methods: Thirty pairs of lungs were used for the study, obtained from formalin-fixed cadavers of south-indian origin. The lung specimens were observed for the patterns of lobes and fissures, variations were noted and specimenswere photographed. Results: Five right lungs showed absence of horizontal fissure. Out of thirty, twelve right sided lungs showed incomplete fissures.On the left side, seven specimens showed incomplete oblique fissure. In addition, two right-sided specimens and four left sided specimens showed presence accessory fissure. Conclusion: The results and their comparison with the previous works show that there is a wide range of difference in occurrence of major, minor and accessory fissures between and among different populations. Knowledge of such variations is mandatory for surgeons in pre-operative planning for performing pulmonary lobectomies and for radiologists for interpreting X-rays and CT scans.

    Study of association of Epstein Barr-virus with Hodgkin's disease.
    (1997-07-01) Radha, K; Shanthi, P; Madhavan, M; Senthamarai, A
    Epstein Barr-Virus (EBV) is a lymphotropic herpes virus, well recognised for its oncogenic properties. In recent years substantial evidence has accumulated supporting a role for EBV in the pathogenesis of Hodgkin's disease. The epidemiologic and histologic features of Hodgkin's disease (HD) have long indicated a possible infective cause. Our study involves the detection of the EBV encoded latent membrane protein 1 (LMP-1) in 45 cases of Hodgkin's disease using immunohistochemical methods. In this study we detected LMP-1 positivity in the Reed-Sternberg and Hodgkin's cells in 31% of cases of HD. In mixed cellularity the positivity was 21.7% while nodular sclerosis exhibited positivity of 50% of the cases. The lymphocyte depletion subtype showed 100% positivity. All cases of lymphocyte predominance and the single unclassified case were negative for LMP. The demonstration of LMP-1 in Hodgkin's disease has important implications since it is one of the latent gene products which produces B Lymphocyte transformation.

    Study of palmar patterns in diabetic patients.
    (2014-08) Sudagar, M; Radha, K; Duraipandian, K; Sundaravadhanam, K V K
    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.

    Study on Branching Pattern of Arch of Aorta in South Indian Population.
    (2014-10) Pandian, Durai K; Radha, K; Sundaravadhanam, K V K
    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.
