Risk factors include the lack of appropriate hospital facilities such as isolation units, bed space, and sinks;inadequate waste management, contaminated equipment, inappropriate use of antibiotics and transmission of infection from the hands of healthcare workers and family caretakers due to inadequate hand washing. Nosocomial infections increase the costs of healthcare due to added antimicrobial treatment and prolonged hospitalization. Since the prevalence of nosocomial infections is generally higher in developing countries with limited resources, the socio-economic burden is even more severe in these countries. This review summarizes the current knowledge on the risks of hospital acquired infections and summarizes current recommendations for the development of hospital infrastructure and the institution of protocols to reduce these infections in LMICs such as Bangladesh.展开更多

In a large proportion of cases, the aetiology of diarrhoea remains unknown but is often attributed to multiple pathogens including parasites.AIM To identify and describe the pathogens causing diarrhoea in Bangladeshi children with cancer.METHODS Two cross-sectional pilot studies were conducted involving paediatric oncology patients with diarrhoea. Stool samples were collected from children who were hospitalised with or without being treated with chemotherapy during the study period, and had diarrhoea at any stage during their admission. In the first study,stool samples were tested by conventional microbiological methods and by polymerase chain reaction for parasites, and by immunoassays for Clostridium difficile. In the second study, conventional microbiology was conducted for bacteria and parasites including an enzyme-linked immunosorbent assay for Cryptosporidium antigen, and in a subset, immunoassays for Clostridium difficile.RESULTS In the first study Giardia lamblia was detected in 68.5% of samples, Entamoeba histolytica in 13%, Cryptosporidium in 5.6%, non-toxigenic C. difficile in 22.4%, and other bacteria in 5.2%. In the second study, E. histolytica was detected in 10% of samples, Cryptosporidium in 4.3%, G. lamblia in 1.4%, C. difficile in 5.1%, and other bacteria in 5.7% of samples.CONCLUSION These pilot data suggest that parasites are important aetiologies of diarrhoea in Bangladeshi children with malignancy. While molecular diagnostic tools detect an array of stool pathogens with greater sensitivity, conventional diagnostic methods are also useful.展开更多

An understanding of its risk factors is important. Methods: A case control study was conducted in the Department of Obstetrics and Gynecology of Sir Salimullah Medical College & Mitford Hospital, in Dhaka, Bangladesh from January to June 2014 to evaluate the risk factors of postoperative surgical site infection following CS. One hundred patients were studied. Results: Fifty patients of post CS wound infection (surgical site infection: SSI) were selected as cases. Body mass index > 25 (kg/m2), anemia (p = 0.001), prolonged rupture of membrane (p = 0.005), prolonged operation time (p = 0.019), and junior surgeons performing the operation (p = 0.011) were the risk factors for CS-SSI. Conclusions: Pre- and postoperative care and surgical training of junior doctors should be directed to these risk factors.展开更多
