Methods: The intervention comprised an enhanced supervision training to lady health supervisors (LHSs) and written feedback to LHWs by LHSs, implemented in Districts Badin and Mirpur Khas (MPK). Clinical skills of LHWs and LHSs and supervision skills of LHSs were assessed before, …

Oral Rehydration Therapies In Senegal, Mali, And Sierra Leone: A Spatial Analysis Of Changes Over Time And Implications For Policy, Kirsten E. Wiens, Lauren E. Schaeffer, Samba O. Sow, Babacar Ndoye, Carrie Jo Cain, Mathew M. Baumann, Kimberly B. Johnson, Paulina A. Lindstedt, Brigette F. Blacker, Zulfiqar Ahmed Bhutta

Woman and Child Health

Background: Oral rehydration solution (ORS) is a simple intervention that can prevent childhood deaths from severe diarrhea and dehydration. In a previous study, we mapped the use of ORS treatment subnationally and found that ORS coverage increased over time, while the use of home-made alternatives or recommended home fluids (RHF) decreased, in many countries. These patterns were particularly striking within Senegal, Mali, and Sierra Leone. It was unclear, however, whether ORS replaced RHF in these locations or if children were left untreated, and if these patterns were associated with health policy changes.
Methods: We used a Bayesian geostatistical model and …

Community Health Sciences

BACKGROUND:

Where access to facilities for childhood diarrhea and pneumonia is inadequate, community case management (CCM) is an effective way of improving access to care. In Pakistan, utilization of CCM for these diseases through the Lady Health Worker Program remains low. Challenges of access to facilities persist leading to delayed care and poor outcomes. Estimating caregiver knowledge, understanding their perceptions and practices, and recognizing how these are related to care seeking decisions about childhood diarrhea and pneumonia is crucial to bring about coherence between supply and demand-side practices.

METHODS:

Data was collected from family caregivers to explore their knowledge, perceptions …

Department of Paediatrics and Child Health

Background: Solar Water Disinfection (SODIS) is a simple, inexpensive and sustainable means of daily household treatment for drinking and storage of water. Globally, over a billion people lack access to safe drinking water. As many as half million under five children die annually due to diarrheal illnesses. Most of these deaths are concentrated in Africa and South Asia. Unsafe water is one of the most critical risk factors for diarrhoea. Systematic reviews indicate that interventions to improve the microbial quality of drinking water in households are effective at reducing diarrhoea illnesses and thereby contribute significantly in reducing deaths due to …

Is There An Association Of Giardiasis With Beta-Thalassemia Minor?, Javed Yakoob, Wasim Jafri, Hizbullah Shaikh

Section of Gastroenterology

Beta–thalassemia minor is a symptomless carrier state of a hemoglobinopathy which predisposes to bacterial infections. We report three cases presenting with giardiasis, a parasitic infection of gastrointestinal tract caused by Giardia lamblia. Patients presented with recurrent diarrhea and abdominal pain for over a year. An esophagogastroduodenoscopy finding varied from normal to acute duodenitis. Duodenal biopsy demonstrated changes consistent with mild chronic non-specific inflammation with G. lamblia trophozoites. All three patients were diagnosed as β -thalassemia minor hemoglobin electrophoresis. They were treated with Diloxanide furoate 500 mg and Metronidazole 400mg three times daily for five days. Their symptoms resolved and a …
