Clinico-Demographic Characteristics of Intestinal Tuberculosis in Pre-Operative Unsuspected Laparotomy as Incidental Findings in Bangladesh

Background: Clinical presentation of intestinal tuberculosis is varied. It is also essential to know the clinical and demographic characteristics of incidentally detected intestinal tuberculosis patient. Objective: The purpose of the present study was to find out the clinic-demographic characteristics of intestinal tuberculosis in clinically and preoperatively unsuspected laparotomies. Methodology: This cross-sectional study was carried out in the Department of Surgery at Dhaka Medical College Hospital, Dhaka from March 2002 to March 2004 for a period of two (2) years. All the patients underwent laparotomy presented without any suspicion of pulmonary or intestinal tuberculosis were included as study population. Patients who were without the history of cough, haemoptysis, antitubercular drug therapy were included. Per operative suspicion was raised due to enlarged lymph nodes in mesentery, omental masses, ileocaecal masses, suspicious growth in ileum, omental thickening, perforation suspected by tuberculosis. Biopsy was taken from suspicious lesions. Histopathology was confirmed the tubercular lesion. Results: A total number of 300 patients under laparotomy were recruited for this study of which 38 positive cases were found in the study with a percentage of 12.7%. Maximum affected age group was 21 to 30 years which was 16 (42%) cases. Male was predominant to female which was 28 (73.7%) cases and 10 (26.3%) cases respectively. Low socioeconomic people are affected more (76.3%). Most common presentation in positive cases was acute and sub-acute intestinal obstruction 20 (52.6%) followed by intestinal perforation (26.31%). Conclusion: In conclusion young age male patient is the most commonly affected intestinal tuberculosis which is frequently presented with sub-acute intestinal obstruction among the preoperatively unsuspected laparotomy patients.

Investigation of the Physical Properties of Jute Blended Yarn Using a Novel Approach in Spinning Process

This work reports the successful outcomes to process the polyester, acrylic and wool fiber along with jute fiber exclusively using existing jute processing machineries for manufacturing the 241 tex jute blended yarn. The blending was performed at feeding stage of breaker carding machine and blending ratio of jute and polyester/acrylic/wool fibers is 80:20. Manufacturing of jute blended yarns will create a new opportunity for extending the uses of jute fibers in value added jute products. The present work is concerned with the investigation of physical properties such as tenacity, elongation % at break, quality ratio, unevenness, imperfections (thick, thin & neps) and hairiness of manufactured jute blended yarns. The jute-polyester (80/20) blended yarn shows the higher strength and more evenness compared to jute-acrylic (80/20), jute-wool (80/20) blended and 100% jute yarn.
