This study examined the clinical signs and symptoms in 897 children aged under 5 years presenting with pneumonia to Goroka Hospital in the highlands of Papua New Guinea between June 1982 and July 1985. The usefulness of the signs in predicting severity of disease was determined and risk factors for severe disease were identified. While cyanosis and poor(More)
An enteric coronavirus that is antigenically closely related to feline infectious peritonitis virus (FIPV) is ubiquitous in the cat population. This virus has been designated feline enteric coronavirus to differentiate it from FIPV. The virus is shed in the feces by many seropositive cats; in catteries it is a cause of inapparent to mildly severe enteritis(More)
BACKGROUND Psoriasis, a chronic inflammatory skin disease, affects approximately 2% of the population worldwide. Although the aetiology of psoriasis is poorly understood, patients with disease of early onset (Type I, age of onset<or=40 years) usually have a strong genetic component to the disease. OBJECTIVES The purpose of this study was to investigate(More)
BACKGROUND The use of methotrexate is limited by interindividual variability in response. Previous studies in patients with either rheumatoid arthritis or psoriasis suggest that genetic variation across the methotrexate metabolic pathway might enable prediction of both efficacy and toxicity of the drug. OBJECTIVES To assess if single nucleotide(More)
BACKGROUND Filaggrin loss-of-function (FLG) mutations are associated with eczema and skin barrier impairment, but it is unclear whether skin barrier impairment precedes phenotypic eczema in FLG mutation carriers. OBJECTIVES To study the association between FLG mutations, skin barrier impairment and clinical eczema at 3 months of age. METHODS A total of(More)
Haemoglobin Bart's was detected in cord blood samples from 81% of 217 infants born in Madang on the north coast of Papua New Guinea. Analysis of the alpha globin genes of 30 infants and adults from the same region showed that all but 3 were heterozygous or homozygous for the deletion form of alpha + thalassaemia. None of 18 cord blood samples from infants(More)
It is important to define clinical signs that can be used to identify children who have a high risk of dying from pneumonia so that these children can be given more intensive therapy. We prospectively studied 748 children in Papua New Guinea who had severe pneumonia, as defined by the World Health Organization. There was a very high mortality in children(More)
The reported geographical association between Alzheimer's disease and levels of aluminium (Al) in water supplies may reflect the inverse relation between Al and silicon (Si) concentrations in water, and the potential for Si to reduce the bioavailability of the metal. We tested this hypothesis using isotopic 26Al tracer administered orally to five healthy(More)
The commercial milk supply on Oahu was contaminated by heptachlor epoxide for as long as 15 months during 1981-82 at levels possibly as high as 1.2 ug/g, fat basis. Following the contamination, several investigators attempted to evaluate potential adverse health outcomes, especially among infants and young children. However, results of the initial(More)
Burns often happen unexpectedly and have the potential to cause death, lifelong disfigurement and dysfunction. A critical part of burn management is assessing the depth and extent of injury. Burns are now commonly classified as superficial, superficial partial thickness, deep partial thickness and full thickness. A systematic approach to burn care focuses(More)
