Three-Jaw Chuck Pinch Strength and its Correlation with Hand Depth in Electronics Technicians.

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.

An Autopsy Based Study on Socio-economical Pattern of Organophosphorus Poisoning Cases Recorded from Sir Salimullah Medical College Morgue.

Poisoning is one of the commonest methods employed for committing suicide, especially in Developing countries like Bangladesh. In this retrospective study, a total of 114 organophosphorus poisoningcases autopsied at Sir Salimullah Medical College morgue, Dhaka, Bangladesh, were analyzed during the period from January 2016 to December 2017. Male predominance was noted accounting for 75% of total cases compared to females 25% cases. Most common age group involved was 21-30 years 31% followed by 31-40 years 22% belonging to lower socioeconomic status. Suicide was the commonest manner of death in majority of cases. The reason may be the increasing stress in the family and economic constraints. Accidental deaths due to occupational exposure or inhalation of OPC compounds are reported but in these cases mortality rate is less than that suicidal poisoning. To reduce poisoning cases proper emphasis should be given for safe use of pesticides and consciousness should becreated among the population about poisonous compounds.

A Study to find out the Correlation between Handgrip Strength and Hand Breadth of Bangladeshi Male Cricket Batsman.

This cross sectional analytical type of study was conducted at department of Anatomy, Dhaka Medical College, Dhaka, Bangladesh from July 2015 to June 2016 on 50 adult Bangladeshi male sprinters (Group A) and 50 adult Bangladeshi male cricket batsman (Group B). Sample collection was done by convenient purposive sampling technique. History of any injury of hand during playing was excluded to construct standard measurement. Hand breadth was measured with the help of slide calipers. Hand grip strength Dynamometer was used to measure the hand grip strength. Paired Student's 't' test, unpaired student's 't' test and Pearson's correlation coefficient test were done for statistical analysis of the result. The aim of the present study was to determine hand breadth and average hand grip strength of Bangladeshi male cricket batsman to find out correlation between them that may be used as a baseline for other professions as well for future research in our country. The mean right and left hand grip strength was significantly higher in the cricket batsman than in the sprinters. The mean right and left hand breadth was found to be significantly higher in the cricket batsman than in the sprinters. Right and left hand grip strength showed significant positive correlation with hand breadth in both hand. The study findings suggest that regular physical exercise and training increase hand grip strength.

Comparative Study between Conventional Method and Endonasal Endoscopic Resection of Juvenile Nasopharyngeal Angiofibroma.

Juvenile Nasopharyngeal Angiofibroma (JNA) is an uncommon, benign and extremely vascular tumour which accounts for 0.05-0.5% of all head and neck tumours. Now a day, endoscopic excision is a preferred surgery for early cases. This study was done with the aim to compare the outcomes and complications between endoscopic and conventional surgery of JNA. This cross sectional observational study was conducted in the Department of Otolaryngology & Head-Neck Surgery at Mymensingh Medical College Hospital, Mymensingh and Bangabandhu Sheikh Mujib Medical University, Dhaka from 8 March 2014 to 7 March, 2015. A total number of 20 cases were purposively selected and patient with intracranial extension were excluded from the study. Data was analyzed with SPSS software. Among the 20 patients, maximum 18(90%) were in 2nd decade, age was ranging from 11-33 years, mean 16.17 years. Maximum patients 13(65%) came with nasal obstruction and epistaxis and majority 13(65%) of them were in stage II. Endoscopic excision was done in 12(60%) cases and conventional surgery was done in 7(35%) cases. Mean hospital stay of endoscopic and conventional group was 4.62 vs. 10.23 days. Mean blood loss and mean operative time were 528.12ml vs. 1050ml and 2 hours 17 minutes vs. 3 hours 28 minutes respectively. Per-operative and postoperative complication were more (53.85%) in conventional surgery group. Endoscopic excision of nasopharyngeal angiofibroma is more preferable due to less operative time, less hospital stay, less per-operative blood loss and less complications. But in advanced cases conventional surgery and combined surgery is preferred.
