The fact that breastfeeding may protect against allergic disease remains controversial, with hardly any reports from developing countries. This study investigated the association between allergic disease in children and prolonged breastfeeding. Data were collected from a 15% random sample of households from two poor suburbs of Cape Town, South Africa.(More)
BACKGROUND Diagnosis of childhood tuberculosis is problematic and symptom based diagnostic approaches are often promoted in high burden settings. This study aimed (i) to document the prevalence of symptoms associated with tuberculosis among randomly selected children living in a high burden community, and (ii) to compare the prevalence of these symptoms in(More)
BACKGROUND The diagnosis of childhood pulmonary tuberculosis presents a major challenge as symptoms traditionally associated with tuberculosis are extremely common in children from endemic areas. The natural history of tuberculosis in children shows that progressive disease is associated with symptoms which have a persistent, non-remitting character. The(More)
UNLABELLED Human non-polio enterovirus (EV) is the most important cause of aseptic meningitis in children. Only a few studies report the lack of cerobrospinal fluid (CSF) pleocytosis in children with confirmed EV meningitis; however, the characteristics of these children have not been well defined. This paper describes the clinical and laboratory features(More)
Acute respiratory tract infections are an important public health problem. Sensitive and rapid diagnostic techniques have been developed and are used in daily clinical practice. Here we evaluate the clinical relevance of detecting 20 common respiratory pathogens by molecular methods in a general pediatric clinic. Nasopharynx samples of children < 18 years(More)
BACKGROUND Reverse-transcriptase quantitative real-time polymerase chain reaction (RT-qPCR) has become the gold standard for the diagnosis of human enterovirus (EV) and parechovirus (HPeV) infections. The detection rate of RT-qPCR in different pediatric body specimens has not been compared prospectively in a multicentre study. OBJECTIVES This study(More)
Enterovirus (EV) and human parechovirus (HPeV) are a major cause of infection in childhood. A rapid diagnostic test may improve the management of patients with EV and HPeV infection. The aim of this study is to evaluate the performance of the GeneXpert enterovirus assay (GXEA) for detection of EV RNA compared to a user-developed reverse-transcriptase (RT)(More)
UNLABELLED Enterovirus and parechovirus are a frequent cause of infection in children. This review is an overview of what is known from enterovirus and parechovirus infection in children and contains information about the epidemiology, pathogenesis, clinical presentation, diagnosis, treatment, and prognosis of enterovirus and parechovirus infection in(More)
BACKGROUND Human non-polio enterovirus (EV) and human parechovirus (HPeV) are important pathogens of viral infection and aseptic meningitis in children. The aim of this study is to prospectively compare the incidence, clinical signs, blood and cerebrospinal fluid in EV and HPeV infected children. OBJECTIVES To compare the clinical symptoms and laboratory(More)
