OBJECTIVE To determine the effect of transfusion on hematologic recovery and mortality among severely anemic children during and after hospitalization in rural Kenya. DESIGN Prospective cohort. METHODS We collected clinical and laboratory information on all severely anemic children (hemoglobin < 5.0 g/dl) and a 33% sample of children with hemoglobin <(More)
The possibility that chemicals induce skin irritation by multiple mechanisms was studied in laboratory mice. The time course and dose response to topical application of phenol, croton oil, benzalkonium chloride, ethyl phenylpropiolate (EPP), and methyl salicylate were compared. The responses to each chemical were measured as changes in ear thickness(More)
Plasmodium falciparum infection is an important cause of the high childhood mortality rates in sub-Saharan Africa. Increasingly, the contribution of P. falciparum-associated severe anemia to pediatric mortality is being recognized while the impact of chloroquine resistance on mortality has not been evaluated. To address the issues of pediatric mortality,(More)
Pneumonia causes 3.2 million deaths per year in children under 5 years old according to the World Health Organization. In spite of the number of deaths, no single clinical or radiological definition for the diagnosis of pneumonia is widely accepted. To determine the extent of agreement between clinical and radiographic diagnoses of pneumonia, we compared(More)
The time course, dose response, components of inflammation, and involvement of putative mediators of inflammation in irritation induced by different chemicals was compared using a mouse ear swelling technique. Differences in time courses of inflammation produced by the irritants were not solely due to differences in rates of penetration. Changes in blood(More)
tert-Butyl hydroquinone (TBHQ) has important and functional uses in consumer and commercial applications, some of which involve human exposure primarily through dermal contact. To assist in the safety evaluation of TBHQ, this study was conducted to determine whether TBHQ would produce changes in skin pigmentation after repeated dermal application to black(More)
Although primary human immunodeficiency virus infection (PHI) is usually symptomatic and early management is likely important, the diagnosis is infrequently made. We examined a prospectively enrolled cohort of individuals diagnosed as having PHI in the southeastern United States to determine problems associated with the diagnosis of PHI. The following(More)
To determine the value of clinical findings for the diagnosis of pneumonia, we evaluated 950 children who presented with respiratory illness to the outpatient department of the Queen Elizabeth II Hospital, Maseru, Lesotho. Those children at high risk for pneumonia and a systematically selected 20% sample of children at low risk were examined in turn by a(More)
The World Health Organisation has developed disease-specific clinical case-definitions to guide management of children with fever or cough, the cardinal signs of malaria and pneumonia. To assess the usefulness of the case-definitions and to investigate their interaction, we studied children with fever or cough brought to a hospital in Lilongwe, Malawi. For(More)
