C-reactive protein in children with malaria in Luanda, Angola: a prospective study.

Background: C-reactive protein (CRP) is an acute phase reactant of which little is known in malaria, especially in central Africa.

Methods: In this prospective study CRP was measured in children with suspected malaria.

Results: Of 346 children, 234 had positive and 112 negative malaria microscopy.

Changes in MMP-9 and TIMP-1 Concentrations in Cerebrospinal Fluid after 1 Week of Treatment of Childhood Bacterial Meningitis.

We explored the changes of the initially highly upgraded cerebrospinal fluid matrix metalloproteinase 9 (MMP-9) and tissue inhibitor of MMP 1 (TIMP-1) response during recovery of childhood bacterial meningitis and their association with outcome. The sizes of these changes varied substantially, but a steeper decrease in the MMP-9 and an increase of the TIMP-1 concentrations augured a better outcome.

Triosephosphate isomerase gene promoter variation: -5G/A and -8G/A polymorphisms in clinical malaria groups in two African populations.

TPI1 promoter polymorphisms occur in high prevalence in individuals from African origin. Malaria-patients from Angola and Mozambique were screened for the TPI1 gene promoter variants rs1800200A>G, (-5G>A), rs1800201G>A, (-8G>A), rs1800202T>G, (-24T>G), and for the intron 5 polymorphism rs2071069G>A, (2262G>A). -5G>A and -8G>A variants occur in 47% and 53% in Angola and Mozambique, respectively while -24T>G was monomorphic for the wild-type T allele.

Ventricular septal defect in children and adolescents in Angola: experience of a tertiary center.

Introduction And Objective: This is the first study in Angola with the aim of characterizing ventricular septal defect (VSD) among children and adolescents.

Methods: A cross-sectional study based on echocardiographic records of the largest pediatric cardiology center in Angola included all children and adolescents (0 to 18 years old) with VSD between April 2010 and March 2011. The diagnosis was made by transthoracic and Doppler echocardiography with a Medison SA 8000 system.

Prognostic accuracy of five simple scales in childhood bacterial meningitis.

Background: In childhood acute bacterial meningitis, the level of consciousness, measured with the Glasgow coma scale (GCS) or the Blantyre coma scale (BCS), is the most important predictor of outcome. The Herson-Todd scale (HTS) was developed for Haemophilus influenzae meningitis. Our objective was to identify prognostic factors, to form a simple scale, and to compare the predictive accuracy of these scales.

Risk factors for death and severe neurological sequelae in childhood bacterial meningitis in sub-Saharan Africa.

We report a morality rate of 33% among 403 children with bacterial meningitis in Angola. A fatal outcome was associated with impaired consciousness, severe dyspnea, and seizures, and severe neurological sequelae (found in 25% of our patients) was associated with delayed presentation to the hospital, impaired consciousness, and seizures. Being underweight was of secondary importance.

Acute childhood bacterial meningitis in Luanda, Angola.

Incidence, morbidity and mortality of bacterial meningitis in developing countries are manifold greater than those in the industrialized world. We reviewed retrospectively children with meningitis treated in the paediatric hospital of Luanda in 2004. Among the 555 children, median age 11.
