ReviewNoma: a neglected scourge of children in sub-Saharan Africa.
Poverty is the single most important risk indicator for noma (cancrum oris), a severe gangrene of the soft and hard tissues of the mouth, face, and neighbouring areas. The risk factors associated with an increased probability of noma developing include the following: malnutrition, poor oral hygiene, and a state of debilitation resulting from human immunodeficiency virus (HIV) infection, measles, and other childhood diseases prevalent in the tropics. ⋯ The current escalation in the incidence of noma in Africa can be attributed to the worsening economic crisis in the region, which has adversely affected the health and well-being of children through deteriorating sanitation, declining nutritional status and the associated immunosuppression, and increased exposure to infectious diseases. Prevention of noma in Africa will require measures that address these problems, and most importantly, eliminate faecal contamination of foods and water supplies.

Anaemia is a serious and common problem among young children in sub-Saharan Africa. As a first step towards developing guidelines for its recognition and treatment, we conducted a study to evaluate the ability of health workers to use clinical findings to identify children with anaemia. ⋯ Pallor of the conjunctiva, tongue, palm or nail beds was 66% sensitive and 68% specific in distinguishing children with moderate a anaemia (haemoglobin concentration, 5-8 g/dl) and 93% sensitive and 57% specific in distinguishing those with severe anaemia (haemoglobin concentration, < 5 g/dl). Even without laboratory support, which is often unavailable in rural Africa, clinical findings can identify the majority of children with anaemia.

Case ReportsDengue type 1 epidemic with haemorrhagic manifestations in Fiji, 1989-90.
A dengue type 1 epidemic occurred in Fiji between July 1989 and July 1990. Virus isolation in C6/36 cell cultures and Toxorhynchites mosquitos yielded 36 strains. ⋯ Among the children and adults hospitalized for dengue, 43% had haemorrhagic manifestations, including epistaxis, gingival bleeding, haematemesis, melaena and haematuria. A total of 15 patients with haemorrhagic manifestations and/or shock died, 10 of whom were aged 0-15 years; the diagnoses were confirmed in four cases by virus isolation or serology.

Use of body mass index of adults in assessing individual and community nutritional status.
Adult malnutrition is much more widespread than is commonly recognized. Described in this article is the use of body mass index (BMI = weight in kg/(height in metres)2) as a measure of adult nutritional status, both of individuals and of communities. ⋯ Included is a tabular presentation that permits rapid assessment of both thinness or underweight (BMI values < 16, 17 and 18.5) and overweight (BMI > 25, 30 and 40). Examples of the use of BMI in both clinical and public health practice are also given.

Reported are the results of a study of residents' knowledge about malaria and antimalarial drugs and of their treatment-seeking behaviour in a rural area of western Kenya. The study subjects were generally well-informed about the symptoms of the disease. Malaria was perceived as a relatively mild illness, much less severe than acquired immunodeficiency syndrome (AIDS), measles, difficulty in breathing, and diarrhoea. ⋯ Commercially available chloroquine preparations were perceived as more effective than either antipyretics or herbal remedies for the treatment of malaria, and injections were regarded as more effective than oral medications. 4-Amino-quinolines were used to treat 58% of febrile illnesses but in only 12% of the cases was a curative dose of > or = 25 mg/kg body weight employed. Even attendance at a health centre did not ensure adequate treatment because of the common practice of sharing medication among family members. Greatly increased attention should be paid to the role of home treatment of malaria when policies are being developed for the management of febrile illnesses in sub-Saharan Africa.
