ABSTRACT
Background & objectives: Stature is considered as the height of a person measured in erect position. It is one of the most important factors in establishing identity of a person. In certain medico-legal cases, where only parts or fragments of human body are found. Such a need arises when there is mass casualty. Aim of current study was to establish anthropometric correlation of stature with hand length and foot length in population of Gujarat and also to derive regression equations for correct estimation of stature of male and female in Gujarati population. Material and Method: 150 asymptomatic, apparently healthy, adolescent and adult medical students with age between 18 to 22 years belonging to various regions of Gujarat were selected. Left foot and left hand was selected for measurement. Result: Regression equation for estimation of height using both foot length and hand length were formulated. By using the derived regression equations, height of subjects was calculated and then compared with actual height of subjects. Conclusion: By the present study we conclude that both foot and hand length can be used in estimation of stature of both males and females with fairly accurate results in Gujarati population.
ABSTRACT
Introduction: The sinuatrial (SA) node is known as natural pacemaker of the heart. SA node is supplied by the sinuatrial (SA) nodal artery is an atrial branch. Ischemia of SA nodal artery due to injury or during surgical intervention leads arrhythmia. Origin of sinuatrial (SA) nodal artery is variable; most commonly arise from right coronary artery. It may arise from the circumflex branch of the Left circumflex artery (LCA). In some cases it may originate from the trunk of left coronary artery, aorta or left bronchial artery. SA node may be supplied by single SA nodal artery or may have dual and triple arterial supply. Methods: This study was conducted on 25 cadavers from the dissection laboratory with an age range of 50 – 70 years. The cadavers were embalmed through carotid arterial perfusion of formaldehyde solution, spirit, water and glycerine and preserved in a weak formalin solution before dissection. Dissection method was employed for this study. Result and Observation: Single SA nodal artery found in 22/25 hearts (88%) and dual supply found in 3/25 hearts (12%). The SA nodal artery originated from proximal segment of right coronary artery (RCA) in 16/25 hearts (64%), from proximal segment of circumflex branch (LCX) of left coronary artery (LCA) in 6/25 hearts (24%). The Mean+SD of diameter of SAN artery from right coronary artery was 1.7+0.42mm. The Mean+SD of diameter of SAN artery from circumflex branch of left coronary artery was 1.29+0.30mm. The termination types were 1) precaval found in 44% (11/25), 2) retrocaval in 52% (13/25) and 3) pericaval found in 4%(1/25) of all SA nodal arteries.Conclusion: To be aware of the origin and course of SAN artery may provide a safe approach to interventional cardiologist and cardiac surgeon during cardiac interventions. Cardiac surgeons especially should be careful because compensation.
