These findings demonstrate the usefulness of anthropometric craniofacial pattern profiles in defining abnormal craniofacial dimensions in Down syndrome patients.
Background: The supracondylar process of the humerus, which is also called the supra-epitrochlear, epicondylar, epicondylic process or a supratrochlear spur, is a hook-like, bony spine of variable size that may project distally from the anteromedial surface of the humerus. It represents the embryologic vestigial remnant of climbing animals and seen in many reptiles, most marsupials, cats, lemurs and American monkeys.
Background: Coronary arteries are the branch of ascending aorta and it is the main arterial supply of the myocardium of the heart. Left coronary artery (LCA) usually arises from left posterior aortic sinus. The site of manifestation of myocardial infarction depends on the occlusion of an artery or its branches involved in atherosclerosis. To know the site of lesion and occlusion of the particular artery, detailed anatomy of its course, branches and variations to be studied in detail.Methods: Study was conducted on 55 heart specimens in Department of Anatomy at Sri Siddhartha Medical College (SSMC), Sri Siddhartha Academy of Higher Education (SSAHE). The left coronary artery was dissected carefully, and it was traced from its origin. Any variation in the course and branching pattern was recorded and photographed.Results: No variation was found in the origin of LCA. In the present study, the most frequent division pattern of the left coronary artery was observed as the bifurcation in 30 specimens (54.54%) followed by trifurcation in 23 specimens (41.82%). Tetrafurcation and pentafurcation of LCA were observed in one specimen each (1.82%).Conclusions: Our study tries to focus on branching pattern of LCA for the better knowledge of accurate diagnosis and therapeutic intervention in the management of coronary artery diseases.
The supratrochlear foramen (STF) is an important and relatively common anatomic variation in the lower end of the humerus in humans. The present study on south Indian population is an attempt to highlight the incidence, morphological features and clinical importance of STF. The study was conducted on dried human humeri of unknown sex and free of pathological changes. The presence of a STF was noted for its shape and divided into three types (oval, round, and irregular). In bones where the foramen was absent the translucency of the septum between the coronoid and the radial fossa was noted by placing the lower end of the humerus against the X-ray view box. Out of the 142 humeri studied, 72 humeri (50.7%) were right sided and 70 humeri (49.2%) were left sided. In these 142 humeri, 38 humeri (26.7%) showed the presence of STF. The majority of STF were round shaped in 47.37%, followed by oval shaped in 42.11% and 10.53% were irregular in shape. The STF was absent in 36 humeri (25.35%) and 68 humeri (47.89%) showed the translucency of septum. The mean transverse diameter on right side was 4.50±3.183 mm and 3.32±3.222 mm on left side. The mean vertical diameter was 3.88±2.391 on right side and 3.68±3.532 mm on left side. Its existence is important to the orthopaedician in the preoperative planning of nailing fractures of the distal humerus and to the radiologist for differentiating it from an osteolytic or cystic lesion.
Introduction: Dermatoglyphics is the study of epidermal ridges and their configurations on the palmar and the plantar regions. Currently dermatoglyphics is being used as a tool in the field of biology, anthropology, genetics and medicine to explain, compare and to predict the occurrence of bio medical events. Finger prints are usually categorized into three basic groups namely arches (60-65%), loops (30-35%) and whorls (5%). Any prenatal insult during this critical period of embryogenesis/organ system development should have an influence on the dermatoglyphic patterns.4Congenital heart defects are a heterogeneous group of diseases in which etiology, importance of genetic as well as environmental factors have been recognized. These defects show a familial tendency but no Mendelian pattern of inheritance has been described. In the present study, finger dermatoglyphic patterns in congenital heart diseases are studied and compared with controls. Subjects and methods: Dermatoglyphics are studied in 100 children with congenital heart diseases, both males and females. The dermatoglyphic patterns of palms and fingers were studied and the information was recorded systematically and statistically analyzed. Results: Ventricular septal defects (VSD) form the majority in the both the males (50%) and females (34.8%) in the congenital heart diseases group, followed by Atrial septal defects (ASD) in both males (20.4%) and females (39.1%). In both, the cases and controls group, it is found that the majority are loops followed by whorls and then the arches. The increase in whorls in congenital heart diseases is statistically significant with p value < 0.001. Comparing the cases with controls it is found that the Whorls (p < 0.001) and the loops (p <0.001) were statistically significant, it means that the Whorls are more frequently found in congenital heart diseases than the controls. Conclusion: Congenital heart diseases are associated with abnormal dermatoglyphic patterns. Increased number of Whorls and decreased number of Arches are seen in the congenital heart disease children. The above fingerprint pattren may help as a diagnostic aid in diagnosis of congenital heart diseases in children. They may also help in distinguishing congenital heart diseases from the functional and acquired heart diseases. A larger sample study is required to ascertain the value of this dermatoglyphic parameter as a diagnostic tool in congenital heart diseases in children.
