Background: Lung function varies with the different body posture of normal individuals. Normal healthy school children adopt different body posture which influences their lung function. This cross sectional observational study was done to assess the effects of different sitting postures on lung function like forced vital capacity (FVC) in healthy school children. Methods: This study was conducted in the Department of Physiology, Chittagong Medical college, Chittagong and K S Nazu Miah High school, Khondokia, Younus Nagar, Hathazari, Chittagong during July 2015 to June 2016. A total of 88 subjects of which 42 male and 46 female students aged between 14-16 years studying in class eight to ten were included by purposive sampling method. FVC were recorded by portable digital spirometer (HI-101, Japan). Data were taken in normal upright sitting, kyphotic and at slumped sitting posture. Unpaired and paired t test and repeated measure ANOVA tests were done using SPSS for windows version 20. Results: The mean value of FVC were significantly (p<0.001) changed in different sitting posture. Kyphotic sitting posture showed no significant difference (p>0.05) comparing to normal upright sitting posture. Regarding slumped sitting posture comparing to normal upright showed significant low values (p<0.001). Female subjects showed significant low FVC (p<0.001) comparing to male subjects. Conclusion: The results of this study suggest that the lung function like FVC is significantly decreased in slumped sitting posture. Bangladesh Med Res Counc Bull 2019; 45: 117-121

Introduction: Dehiscence is the partial or complete separation of previously approximated wound margins as a result of inadequate wound healing. Wound dehiscence is most common following an open wound surgery. It's also known as wound breakdown, wound disruption, or wound separation. Various preoperative and postoperative variables might impact it, and these factors can also influence the patient's result following surgery. Aim of the Study: The aim of the study was to observe the operative findings and outcome of patients with abdominal wound dehiscence that had undergone emergency laparotomy. Methods: This prospective clinical study was conducted at the Department of Surgery, MAG Osmani Medical College, Sylhet, Bangladesh. The study duration was 8 months, from July 2008 to February 2009. A total of 460 participants were selected from those undergoing emergency laparotomy in the study place for this study. A consecutive selection method was followed for the selection of the participants. The participants were divided into two groups depending on whether wound dehiscence was developed or not. Result: All the baseline characteristics (age, body mass index, and smoking habit) of patients except sex were significantly associated with wound dehiscence. The history of receiving steroid and cytotoxic drug were higher in patients with wound dehiscence than that in patients without wound dehiscence. However, the history of receiving the immunosuppressive drug was almost identical between the groups. The patients who did not take hygienic measures or take bath before an operation or change clothing had a higher incidence of wound dehiscence. The mean duration of operation, prolene suture used for closure, midline incision, mass closure technique and drain given had significant influence on development of wound dehiscence. Presence of ascitic fluid, pus and contaminated faecal material demonstrated their significant presence in patients who develop wound dehiscence than .....

Introduction: Dehiscence is a partial or total separation of previously approximated wound edges, due to a failure of proper wound healing. Wound dehiscence primarily occurs after a surgery relating to an open wound. It is sometimes called wound breakdown, wound disruption, or wound separation. It can be influenced by various preoperative and postoperative factors. Various preoperative and postoperative variables might impact it, and these factors can also influence the patient's result following surgery. Aim of the Study: The aim of the study was to observe the risk factors and operative findings of abdominal wound dehiscence cases in emergency laparotomy. Methods: This prospective clinical study was conducted at the Department of Surgery, MAG Osmani Medical College, Sylhet, Bangladesh. The study duration was 8 months, from July 2008 to February 2009. A total of 460 participants were selected from those undergoing emergency laparotomy in the study place for this study. A consecutive selection method was followed for the selection of the participants. The participants were divided into two groups depending on whether wound dehiscence was developed or not. Result: All the baseline characteristics (age, body mass index, and smoking habit) of patients except sex were significantly associated with wound dehiscence. The history of receiving steroid and cytotoxic drug were higher in patients with wound dehiscence than that in patients without wound dehiscence. However, the history of receiving the immunosuppressive drug was almost identical between the groups. The patients who did not take hygienic measures or take bath before an operation or change clothing had a higher incidence of wound dehiscence. The risk factors tuberculosis, diabetes mellitus, jaundice, bronchial asthma, anemia, edema, and dehydration were found significantly higher in wound dehiscent patients compared to those without wound dehiscence. The mean duration of operation, prolene suture used for closure, midline incision, mass closure technique and drain given had significant influence on development of wound dehiscence. presence of ascitic fluid, pus and contaminated fecal material demonstrated their significant presence in patients who develop wound dehiscence than those who did not develop wound dehiscence. Postoperative conditions like abdominal distention, coughing and wound infection tend to be associated with wound dehiscence more frequently than their counterpart. Conclusion: The current study recommends evaluating patient-related risk factors before to surgery and quickly addressing them. A skilled surgeon should do surgery on high-risk patients. The study contends that the development of wound dehiscence is significantly influenced by baseline traits like age and BMI. The degree of patient cleanliness before surgery greatly influences the likelihood of wound dehiscence. According to the study, other factors that may affect the occurrence of postoperative abdominal wound dehiscence include surgical procedures, skin preparation, the length of the procedure, and the type of wound closure. Coughing, vomiting, and subsequent infection are additional postoperative side effects that increase the risk of wound dehiscence.

Introduction: Traumatic gastrointestinal tract perforation is one of the commonest abdominal emergencies. The number of admitted trauma patients just focuses the tip of the iceberg because a lion's share of these ill-fated people with abdominal trauma pass their last breathe on the way to the hospital. So what should we do to counter this epidemic and what necessary steps should be taken to reduce the mortality and improve the morbidity was our aim of the study. Although this small study cannot draw a valid conclusion in comparison to the large series of western situations. This study was designed to present the experience of 50 patients with traumatic gastrointestinal tract perforation who were admitted to the surgery department, at Dhaka Medical College Hospital from July 2007 to December 2007. Cases were selected randomly. Standard protocol was followed for analysis and studying of the factor modifying morbidity and mortality. Aim of the study: The aim of the study was to observe the management and outcome of 50 gut injury cases in a tertiary-level hospital in Dhaka, Bangladesh. Methods: This cross-sectional observational study was conducted at the Department of Surgery, Dhaka Medical College Hospital, Dhaka, Bangladesh. The study duration was 1 year, from January 2007 to December 2007. A total of 50 cases were selected for the purpose of this study from those admitted to the study hospital due to traumatic gut injury. Result: The majority of the patients was male and was of the young group. Penetrating groups (60%) predominate over the blunt group (40%). Penetrating injuries were mainly caused by stab and gunshot injuries on the other hand road traffic accidents were mainly responsible for blunt trauma. 58% of patients were in shock on admission and 48% had associated extra-abdominal injury. 52% of patients were resuscitated successfully by means of blood and I/V fluid and most of them were resuscitated within 1-4 hours. The diagnosis was mainly based on .......
