Community-based rehabilitation for those people with a physical disability is a policy promoted by the World Health Organization. In order to assess whether such a program might be useful to the disabled people of the highlands of Papua New Guinea a survey was conducted which first identified those people with a severe physical disability and then investigated the degree that they were handicapped in terms of their social and physical environment. The survey was performed in the Tari area of the Southern Highlands Province in conjunction with the Papua New Guinea Institute of Medical Research (PNGIMR). By using the PNGIMR demographic surveillance system it was possible to calculate a prevalence level of physical disability (including walking disability, deafness and blindness) of 46 per 10,000 (0.46%). A significant physical disability was identified in 114 people, of whom 54 were given personal interviews to establish their quality of life. The survey found the social and economic situation of disabled people to be generally good although there is a lack of basic material aids for handicapped people. The disabled people and their families do not need extra knowledge about how to care for their disabilities and a formal community-based rehabilitation program would be inappropriate, but they would find mobility aids such as wheelchairs and artificial limbs of enormous help. The regular health care services are widely used although both people with a disability and health service staff are not always aware of the types of treatment which can usefully be provided.(ABSTRACT TRUNCATED AT 250 WORDS)

Nontypeable Haemophilus influenzae (NTHi) is a common microbe frequently isolated from the nasopharynx of children. Bacterial pneumonia is a major cause of morbidity and mortality in children less than 5 years of age, with the burden of disease being greatest in developing countries. Determination of the bacterial aetiology of pneumonia is difficult due to sampling constraints. However, with a combination of sampling approaches, trans-thoracic fine-needle aspiration, blood culture and screened sputum, the evidence strongly suggests that NTHi is a significant causative pathogen of pneumonia in young children. However, further studies are required. The development of a new pneumococcal conjugate vaccine containing H. influenzae protein D has the potential to be beneficial against disease caused by NTHi, including pneumonia. With the implementation of this vaccine in many regions of the world where NTHi disease is endemic, it will be critical to introduce surveillance programs wherever it is used.

This paper briefly describes a journey with pneumonia and the pneumococcus that began in partnership with Ian Riley at the Lae Hospital in 1967 and continues 43 years later. It is a journey that signalled the global emergence of penicillin-resistant pneumococci and played an important role in the licensure of pneumococcal polysaccharide vaccine for use in adults around the world. The journey involved many other people whose experience began in Papua New Guinea (PNG), playing lead roles in the global program to reduce pneumonia deaths in developing countries. But none of this has benefitted Papua New Guineans as it could and should have done. In this paper I assert that substantial benefits could now follow from widespread use of the 23-valent polysaccharide vaccine in PNG adults not suffering from HIV and that there is also good scientific reason why children over the age of 9 months should be offered the potential benefits from use of this vaccine that were demonstrated in PNG in the 1980s. Indeed there are very good medical and economic reasons why it should happen.

Malnutrition is a significant problem in parts of Papua New Guinea, including the Lower Jimi Valley. There is evidence of specific nutritional deficiencies, such as endemic cretinism, but this study focused on protein-energy malnutrition. It found that, in the 1-4 year old population of three remote villages in the Jimi, only 26% were nutritionally normal, 65% were stunted, 7% were wasted and 2% were stunted and wasted. With respect to weight for age, 16% were 80-100% weight for age, 77% were 60-80% and 7% were < 60%. These figures are considerably higher than those of the National Nutrition Survey of 1982-1983; although the Survey data originated from the entire Jimi District rather than only the villages in this study, these findings suggest that malnutrition is a significant and worsening problem in the Lower Jimi Valley.

Oxygen therapy is essential in all wards, emergency departments and operating theatres of hospitals at all levels, and oxygen is life-saving. In Papua New Guinea (PNG), an effective oxygen system that improved the detection and treatment of hypoxaemia in provincial and district hospitals reduced death rates from pneumonia in children by as much as 35%. The methods for providing oxygen in PNG are reviewed. A busy provincial hospital will use on average about 38,000 l of oxygen each day. Over 2 years the cost of this amount of oxygen being provided by cylinders (at least K555,000) or an oxygen generator (about K1 million) is significantly more than the cost of setting up and maintaining a comprehensive system of bedside oxygen concentrators (K223,000). A district hospital will use 17,000 l per day. The full costs of this over 2 years are K33,000 if supplied by bedside concentrators, or K333,000 plus transport costs if the oxygen source is cylinders. In provincial and district hospitals bedside oxygen concentrators will be the most cost-effective, simple and reliable sources of oxygen. In large hospitals where there are existing oxygen pipelines, or in newly designed hospitals, an oxygen generator will be effective but currently much more expensive than bedside concentrators that provide the same volume of oxygen generation. There are options for oxygen concentrator use in hospitals and health centres that do not have reliable power. These include battery storage of power or solar power. While these considerably add to the establishment cost when changing from cylinders to concentrators, a battery-powered system should repay its capital costs in less than one year, though this has not yet been proven in the field. Bedside oxygen concentrators are currently the 'best-buy' in supplying oxygen in most hospitals in PNG, where cylinder oxygen is the largest single item in their drug budget. Oxygen concentrators should not be seen as an expensive intervention that has to rely on donor support, but as a cost-saving intervention for all hospitals.

Assessing the vitamin A status among pre-school-age children is essential for evaluating the magnitude and public health status of vitamin A deficiency in a population. This cross-sectional study assessed the vitamin A status of children aged 6 to 59 months resident in the National Capital District (NCD), Papua New Guinea. Children attending the Children's Outpatient Clinic at Port Moresby General Hospital participated in this study. Informed consent was obtained from parents before using blood samples from their children. Assay of plasma retinol was carried out using the 'Clin-Rep' complete kit for assay of vitamins A and E in plasma by high performance liquid chromatography (HPLC). A commercial enzyme immunoassay kit was used to assay C-reactive protein (CRP) in plasma. Of the 132 children in the study 108 (82%) had received vitamin A capsules. The median plasma retinol concentration of the 132 children was 0.98 micromol/l and the interquartile range 0.65-1.38 micromol/l. Of the 132 children, 35 (27%) had a plasma retinol concentration below 0.70 micromol/l. 75 children (57%) had normal plasma CRP levels and in 57 (43%) the CRP levels were elevated. The median plasma retinol concentration of the children with normal plasma CRP was 1.19 micromol/l and the interquartile range 0.93-1.50 micromol/l. The prevalence of vitamin A deficiency (VAD) in the children with normal plasma CRP was 11%, indicating a moderate public health problem. 74 (56%) males and 58 (44%) females were included in the study. The prevalence of VAD in the male and female children with normal plasma CRP was 14% and 8%, respectively, indicating a moderate public health problem among the male children and a mild public health problem among the female children. The prevalence of subclinical (mild to moderate) and marginal VAD among the children with and without elevated CRP strongly suggests the need for continuous monitoring of the vitamin A status of the vulnerable groups in NCD.

The relationship between HIV (human immunodeficiency virus), food security and nutrition has become increasingly important to practitioners, policy makers and people living with HIV. In this paper we describe for the first time the connection between HIV and antiretroviral therapies, the extent of nutritional counselling for HIV-positive people and food security in Papua New Guinea (PNG). A total of 374 HIV-positive people who were over the age of 16 and who had been on antiretroviral therapy (ART) for more than two weeks were recruited from six provinces, using a non-probability, convenience sampling methodology. A subsample of 36 participants also completed an in-depth qualitative interview. Participants received nutritional advice when beginning ART which focused on three main domains, of which the first two were the most frequently mentioned: what foods to avoid; what foods to eat; and how frequently to eat. 72% of the sample reported that they had experienced an increase in their appetite. Of those who reported that their appetite had increased on ART 33% reported that they did not have enough food to satisfy hunger. People who lived in the capital city, Port Moresby, within the Southern Region of PNG, had significantly more difficulty with food security than those who lived in other regions of the country. Not having enough food was the third most commonly recorded reason for non-adherence to ART. Responses to the HIV epidemic in Papua New Guinea must also begin to address the phenomenon of food insecurity for people with HIV, in particular those who are receiving antiretroviral therapies and who live in the urban areas.
