Objective: To determine the risk factors associated with poor outcome among under-five children with severe anemia in sub Saharan Africa.
Design: Cross-sectional.
Setting: University Teaching Hospital, Nigeria.
Participants: Under-five children presenting with severe anemia (PCV <15%, Hb <5g/dL).
Methods: Between January and June 2006, children admitted with severe anemia were recruited. The biodata, socio-economic status, signs and symptoms were documented for each child after the initial stabilization. Laboratory investigations using blood, stool and urine samples were carried out. Data were analyzed using SPSS version 11.0.
Results: 140 out of the 1,450 patients admitted during the period of study had severe anemia (prevalence 9.7%). Malaria either alone or in combination was the most common cause of severe anemia [n=90 (64.3%)]. 117 patients (83.6%) recovered, while 4(2.8%) left against medical advice and 19 died (case fatality rate 13.6%). The variables associated with mortality were malnutrition (P=0.02), tachycardia (P= 0.03), coma (P<0.001), and absence of blood transfusion (P=0.001). On logistic regression analysis coma (P=0.002), not receiving blood transfusion (P=0.002) and female gender (P=0.04) predicted poor outcome.
Conclusions: The study revealed high mortality rates among under-five children with severe anemia. Coma, malnutrition, female gender and absence of blood transfusion were associated with higher mortality in severe anemia.

Background: In developing countries, due to improper management of domestic animals' exposures, under-five (U5) children have been affected by diarrhoea. However, there is no evidence that shows the presence of diarrhoea-causing pathogens in the faeces of U5 children and animals residing in the same houses in the Sidama region, Ethiopia.
Methods: A laboratory-based matched case-control study was conducted on children aged 6-48 months in the Sidama region of Ethiopia from February to June 2023.

Delays in development that occur during early childhood can have long-lasting consequences, potentially leading to poor academic achievement. Research has shown that the human immunodeficiency virus can have neurotropic effects, which may impact the development of the brain in infected children. However, there is a scarcity of evidence regarding developmental delays among children with human immunodeficiency virus in the study area.

Introduction: Diarrheal diseases are the top cause of preventable death, particularly among children under the age of five in developing countries like Ethiopia. Despite the national level of latrine coverage being 61%, diarrhea is responsible for the deaths of half a million children under 5 years annually. Therefore, this study aimed to assess diarrhea and its associated factors among children in open defecation free (ODF) and open defecation (OD) households of Degem district, Oromia, Ethiopia.
