Between 1982 and 1986 in western Zaire, a pediatrician collected data on 206 children under 5 years old presenting at the Institute Medical Evangelique, a 400-bed mission hospital (60 pediatric beds), in Kimpese with persisting fever despite chloroquine therapy for falciparum malaria, a negative or scanty positive thick film for malaria, and no clear localizing signs of infections. The pediatrician suspected that these cases had an extraintestinal Salmonella infection and took blood, synovial fluid, and/or cerebrospinal fluid samples for diagnostic analyses. Salmonella serotypes other than Salmonella typhi (non-S. typhi) were responsible for most bacteremia cases (83%). The clinical features of non-S. typhi and S. typhi infections were basically the same. The case fatality rate for non-S. typhi and S. typhi an S. typhi infections were 22.7% and 29.4%, respectively. Infants under 6 months old had a significantly higher case fatality rate than older children (relative risk [RR] = 1.7; p .0005; e.g., 66% and 100% for infants under 3 months old). Meningitis was significantly associated with increased mortality, regardless of age (RR = 4.68). Jaundice was the only clinical sign significantly linked to increased mortality (RR = 2.35), especially among children who had S. typhi infection (80%). Mortality occurred significantly more often when children fell ill with Salmonella bacteremia in the late rainy season, coinciding with the peak of malnutrition, than in the dry season (RR = 2.62). Chloramphenicol-resistant non-S. typhi isolated were significantly associated with increased mortality (RR = 3.19). Hemoglobin levels below 6 g (i.e. severe anemia) has a strong link to increased mortality (RR = 1.77). Salmonella bacteremia will become more difficult to treat as antibiotic resistance and the prevalence of HIV infection increases in African countries.

This study aimed at describing cerebral malaria cases findings in the Fann Hospital in Dakar. Data were collected from patients files recorded from 2001 to 2005. One hundred and twenty nine cases of cerebral malaria were admitted to the clinic, accounting for 21.4% of all malaria cases. The sex-ratio M/F was 2.48 and the mean age of patients 28.24 years old +/- 13.7 [12-85 years old]. Patients presented with either coma (91.4%) or mental confusion (10.07%) along with fever (80.6%), convulsions (33.3%). Other severe malaria conditions were observed: jaundice (7 cases), severe anaemia (5 cases), acute renal failure (3 cases), and circulatory collapse (3 cases). Acute pulmonary infection (4 cases) and Salmonella bacteraemia (2 cases) occurred as complications during patient's hospitalisation. The case fatality rate was 20.2% (26 deaths). No neurological sequelae were found among survivors. Cerebral malaria lethality is still high enough to urge for the improvement of working conditions in our clinic. Together with promotion of preventive measures in the community better health care services will help to reduce malaria related morbidity and mortality.

Invasive non-Typhi Salmonella is endemic to sub-Saharan Africa, where it is a leading cause of bloodstream infection. Some host risk factors have been established, but little is known about environmental reservoirs and predominant modes of transmission, so prevention strategies are underdeveloped. Although foodborne transmission from animals to humans predominates in high-income countries, it has been postulated that transmission between humans, both within and outside health care facilities, may be important in sub-Saharan Africa. Antimicrobial resistance to ampicillin, trimethoprim-sulfamethoxazole, and chloramphenicol is common among non-Typhi Salmonella strains; therefore, wider use of alternative agents may be warranted for empirical therapy. Development of vaccines targeting the leading invasive non-Typhi Salmonella serotypes Typhimurium and Enteritidis is warranted. The clinical presentation of non-Typhi Salmonella bacteremia is nonspecific and, in the absence of blood culture, may be confused with other febrile illnesses, such as malaria. Much work remains to be done to understand and control invasive non-Typhi Salmonella disease in sub-Saharan Africa.

Acute schistosomiasis is a systemic hypersensitivity reaction against the migrating schistosomula and eggs. A variety of clinical manifestations appear during the migration of schistosomes in humans: cercarial dermatitis, fever, pneumonia, diarrhoea, hepatomegaly, splenomegaly, skin lesions, liver abscesses, brain tumours and myeloradiculopathy. Hypereosinophilia is common and aids diagnosis. The disease has been overlooked, misdiagnosed, underestimated and underreported in endemic areas, but risk groups are well known, including military recruits, some religious congregations, rural tourists and people practicing recreational water sports. Serology may help in diagnosis, but the finding of necrotic-exudative granulomata in a liver biopsy specimen is pathognomonic. Differentials include malaria, tuberculosis, typhoid fever, kala-azar, prolonged Salmonella bacteraemia, lymphoma, toxocariasis, liver abscesses and fever of undetermined origin. For symptomatic hospitalised patients, treatment with steroids and schistosomicides is recommended. Treatment is curative in those timely diagnosed.
