Unlabelled: : media-1vid110.1542/5972295739001PEDS-VA_2018-1026 BACKGROUND AND OBJECTIVES: Cerebral malaria (CM) causes significant mortality and morbidity in sub-Saharan African children. Reliable morbidity estimates are scarce because of methodological variability across studies.

Brain swelling is a major predictor of mortality in pediatric cerebral malaria (CM). However, the mechanisms leading to swelling remain poorly defined. Here, we combined neuroimaging, parasite transcript profiling, and laboratory blood profiles to develop machine-learning models of malarial retinopathy and brain swelling.

Our goals were to understand the brain magnetic resonance imaging (MRI) findings in children with retinopathy-negative cerebral malaria (CM) and investigate whether any findings on acute MRI were associated with adverse outcomes. We performed MRI scans on children admitted to the hospital in Blantyre, Malawi with clinically defined CM. Two hundred and seventeen children were imaged during the study period; 44 patients were malarial retinopathy-negative; and 173 patients were retinopathy-positive.

Radiologic data are increasingly important in clinical care guidelines for neurologic disorders and in the conduct of clinical trials assessing novel therapies. The infrastructure and expertise for neuroradiologic evaluations remain scarce in resource-limited settings, but where available, MRI and CT capacity can offer new insights into common, globally devastating diseases. In vivo data for frequently fatal tropical conditions such as cerebral malaria have been largely limited to autopsy studies, which only provide information on nonsurvivors at a single point in time.

Abstract. A prospective cohort study of retinopathy-confirmed cerebral malaria (CM) survivors identified 42 of 132 with neurologic sequelae. The 38 survivors with sequelae who were alive when magnetic resonance imaging (MRI) technology became available underwent brain MRIs.

Background: Salmonella enterica serovar Typhi causes an estimated 22 million cases of typhoid fever and 216 000 deaths annually worldwide. We investigated an outbreak of unexplained febrile illnesses with neurologic findings, determined to be typhoid fever, along the Malawi-Mozambique border.

Methods: The investigation included active surveillance, interviews, examinations of ill and convalescent persons, medical chart reviews, and laboratory testing.

Purpose: To describe brain CT findings in retinopathy-confirmed, paediatric cerebral malaria.

Materials And Methods: In this outcomes study of paediatric cerebral malaria, a subset of children with protracted coma during initial presentation was scanned acutely. Survivors experiencing adverse neurological outcomes also underwent a head CT.
