Anthropometry in health assessment: the importance of measurement error.

Anthropometry is the hallmark technique of biological anthropology, and has become increasingly important in health assessments across this century. Although the need for accurate anthropometric measurement has been repeatedly stressed, the ways in which measurement error can influence the characteristics of anthropometric data is poorly appreciated. In this article, guidelines for acceptable measurement error are examined critically, and in light of repeat measurements data collected by the two authors on adults in Papua New Guinea.

Case report 734. Fibroma of tendon sheath eroding 3rd metatarsal bone.

A case is presented of a 37-year-old man with an extrinsic lesion originating in the soft tissue adjacent to the 3rd metatarsal and smoothly eroding the adjacent bone. The operatively confirmed diagnosis of fibroma of tendon sheath was surprising, giant cell tumour of tendon sheath eroding bone being considerably more common; these two lesions are normally impossible to distinguish radiologically.

Variability in body physique, ecology, and subsistence in the Fly River region of Papua New Guinea.

There are some 40,000 indigenous peoples of the Fly River drainage in Papua New Guinea. The 4,000-mm rainfall contour ecologically demarcates hunter-horticulturalist peoples living in the rainforests of the Upper Fly from hunter-gatherer peoples living in the savanna-swamplands of the Middle and Lower Fly. A complex of factors operate to create significant physical differences between Upper Fly peoples and those of the Middle and Lower Fly. The ecological division between rainforests and savanna-swamplands demarcates a clear clinal separation by stature of Upper Fly peoples from those of the Middle and Lower Fly.

Antibody responses to malarial antigens in the Wopkaimin population of the Star Mountains, Papua New Guinea.

Antibody responses to malarial antigens were determined in 614 serum samples collected from the Wopkaimin population of the Star Mountains of Papua New Guinea. In point prevalence surveys made in 1982-1983, 33.7% of the persons examined were infected with Plasmodium falciparum, P. vivax, or P. malariae. Of these, 72.9% were infected with P. falciparum. In a standard fluorescent antibody test, highest level responses were to P. falciparum, followed by P. malariae, P. vivax, and P. ovale. A strong correlation was found between results of the fluorescent antibody tests and those obtained in an enzyme-linked immunosorbent assay using P. falciparum antigens. The failure of immune responses to eliminate these species of Plasmodium in this highly isolated population is discussed.

Free small water-cushions for paraplegics.

Decubitus ulcers on small prominent areas (e.g. the heels) in paraplegic and quadruplegic patients are likely to be a problem in a developing country with limited nursing and physiotherapy services. The use of plastic and silver foil container bags from emptied wine dispensing casks, filled with water, has been found to be a no-cost, effective method of preventing these decubitus ulcers.

An unusual dislocation of the lunate and the wrist.

A case of volar radio-carpal dislocation with complete anterior dislocation of the lunate is reported. The injury was caused, unusually, by forced hyperflexion. The mechanism by which this dislocation is produced and the possible order of events in this injury are discussed by reference to the radiological and operative findings. Successful treatment by closed reduction of the radiocarpal dislocations and open reduction of the lunate is reported, and the relevant literature is briefly reviewed.

Use of seat-belts in Port Moresby.

The number of deaths and serious injuries especially in young people from road traffic accidents is reaching epidemic proportions world-wide, and is especially high in developing countries, with Papua New Guinea (PNG) near the top of the list. A proportion of these deaths and injuries could be prevented by the use of seat-belts. In a study undertaken in Port Moresby the overall belt-wearing rate of front-seat occupants of cars was 11.4%. Small children were often carried unrestrained in the front seat. The projected loss to the country in human and economic terms from these accidents in the remaining years of this century is presented. A strong plea is made to make seat-belt fitting and wearing compulsory in PNG.
