Bangladesh – Faecal sludge management new sanitation challenge | Source: The Daily Star, May 18 2016 |
Emphasising the need for managing the faecal sludge (human excreta) speakers at a roundtable yesterday said this sludge will pose huge threats to environment and public health if not properly managed.

The construction of thousands of pit latrines without thinking of ensuring proper hygienic separation of excreta from human contact and faecal sludge management (FSM) eventually emerged as a second generation sanitation problem for the country, they said at a programme at The Daily Star Centre in the capital.
Practical Action Bangladesh, ITN-Buet, Dushtha Shasthya Kendra (DSK) and The Daily Star jointly organised the programme.
Prof Muhammad Ashraf Ali, a teacher of Bangladesh University of Engineering and Technology, gave a keynote presentation on “Faecal Sludge Management: Key Issues and the Institution and Regulatory Framework.”
He mentioned that only four million or 20 percent of the total population of Dhaka city is currently under the sewerage network coverage while the rest 156 million are covered by on-site system. “In the absence of proper pit-emptying services in the latrines, the pit-contents are often drained into the surrounding low lying areas manually posing a great risk to cleaners and public health,” he observed.

Small Intestine Bacterial Overgrowth and Environmental Enteropathy in Bangladeshi Children. mBio, Jan 2016
Authors: Jeffrey R. Donowitz, Rashidul Haque, et al.
Recent studies suggest small intestine bacterial overgrowth (SIBO) is common among developing world children. SIBO’s pathogenesis and effect in the developing world are unclear. Our objective was to determine the prevalence of SIBO in Bangladeshi children and its association with malnutrition. Secondary objectives included determination of SIBO’s association with sanitation, diarrheal disease, and environmental enteropathy.
The strongest predictors of SIBO were decreased length-for-age Z score since birth (odds ratio [OR], 0.13; 95% confidence interval [CI], 0.03 to 0.60) and an open sewer outside the home (OR, 4.78; 95% CI, 1.06 to 21.62). Recent or frequent diarrheal disease did not predict SIBO. The markers of intestinal inflammation fecal Reg 1β (116.8 versus 65.6 µg/ml; P = 0.02) and fecal calprotectin (1,834.6 versus 766.7 µg/g; P = 0.004) were elevated in SIBO-positive children. Measures of intestinal permeability and systemic inflammation did not differ between the groups.
These findings suggest linear growth faltering and poor sanitation are associated with SIBO independently of recent or frequent diarrheal disease. SIBO is associated with intestinal inflammation but not increased permeability or systemic inflammation.
