RESUMO

The three jaw chuck pinch is a variety of pinch technique where thumb opposes both middle and index fingers. Pinch strength is generally influenced by the health status and level of physical activity of a person. The present study was conducted to measure the correlation of three-jaw chuck pinch strength with hand depth in electronics technicians working in Dhaka Metropolitan City. The data obtained from the study may be used as a base line for other professions as well as for research in our country. This cross sectional, analytical study was carried out in the department of Anatomy, Dhaka Medical College, Dhaka, Bangladesh from July 2015 to June 2016 on 100 adults male electronics technicians and 100 adult sedentary workers. Electronics technicians were considered as case group and sedentary workers were considered as control group. Case group was further subdivided according to their working experiences. Study subjects were selected by convenient purposive sampling technique. Hand depth was measured by digital slide calipers and pinch gauge was used to measure the three-jaw chuck pinch strength. The mean three-jaw chuck pinch strength was significantly higher (p<0.05) in case group than in the control group. Significant difference were also observed between case group and control group in the mean hand depth (p<0.05). Mean hand depth was greater in case group than that of control group. Three-jaw chuck pinch strength showed significant positive correlation with hand depth in case group. Case group was further subdivided according to their working experiences, the mean three-jaw chuck pinch strength and hand depth was significantly higher (p<0.05) in more working experience group than in less working experience group. Three-jaw chuck pinch strength showed significant positive correlation with hand depth.

RESUMO

The anatomy of the pancreatic ductal system has received attention because of its importance in pancreaticobiliary diseases. Any blockage in pancreatic ductal system needs emergency maneuver. A full understanding of the variations in pancreatic ductal pattern is essential in the diagnosis and treatment of pancreatic diseases. In an attempt to gather data on the length of main pancreatic duct the present study was carried out on the pancreas of Bangladeshi male cadaver. The descriptive cross-sectional study was carried out in the department of anatomy Dhaka Medical College from October 2008 to September 2009. Total 50 human pancreatic duct were studied. The samples were divided into 7 different age groups ranged from 10-70 years and above 70 years. Length of the main pancreatic duct was measured in fresh samples by x-ray. Length of the main pancreatic duct of formol saline fixed pancreas was measured in situ and after removal from pancreatic tissue. The results of the present study show that the length of the main pancreatic duct increases with age. In all groups length of the main pancreatic duct was more after total removal from pancreas than in situ and x-ray. The mean±SD length of main pancreatic duct was 14.34±3.10 cm, 16.13±3.26 cm, 12.88±3.28 cm in situ, after total removal and in X-ray respectively. Further studies with large sample in both sexes are recommended. Measurement of bendings of ductal course, number of pancreatic ducts and corrosion casts of pancreatic ducts are recommended. The comparison between endoscopic retrograde cholangio pancreatography (ERCP) findings and the cadaveric dissected specimen findings should also be done.
