The authors have studied 50 records of patients who had presented an acute attack of P. falciparum malaria. Both sexes were equally implied. Young people were predominant. The distribution of cases was about the same in the whole year. The fever decreases on the second day and increases on the third day (300/0). Among the classical signs: relative rarity of hepatomegalia (100/0), splenomegalia (10 0/0), jaundice (140/0), nervous symptoms (100/0). Vomiting is rather frequent (30 0/0). From the cardiovascular point of view a relative bradycardia is observed in 16 0/0 of the cases, and a relative tachycardia in 100/0 of the cases; hypotension in 100/0 of the cases. Electrocardiographic signs are observed in 360/0 of the cases; they are aspecific, concerning mainly ST-T anomalias (22 0/0) and a QT lengthening (200/0). The cardiothoracic ratio is higher than 0.5 in 320/0 of the cases. From the pulmonary point of view the authors have observed symptoms contemporary of the attack: two asthma attacks, three radiologic anomalias reminding of viral pneumopathias. The biological symptoms are mainly transitory functional renal insufficiency in 18 0/0 of the cases. Protection due to AS heterozygosis seems to be confirmed in this study. The efficiency of intravenous quinin treatment is certain.

Using computerized in-patients' discharge records, a descriptive analysis was carried out of all medical admission in 1987 in a general hospital. The survey found that there were a total of 4053 admissions in 1987. A wide range of medical disorders were seen reflecting the lack of subspecialization. Cardiovascular disorders topped accounting for 25.6% of all admissions, followed by gastrointestinal and hepatobiliary disorders 12.8% and respiratory disorders 10.7%. The commonest specific medical disorders seen were hypertension 13.8%, diabetes mellitus 10.2%, ischaemic heart disease 7% and asthma 4.5%. The age, sex, ethnic and geographical distributions of the common medical disorders seen appear to conform to two broad pattern; hypertension, diabetes, ischaemic heart disease and cerebrovascular disease affected the older patients, had even ethic distribution and predominantly urban. Malaria, non-specific fever, viral hepatitis and acute gastroenteritis affected the younger patients, predominantly rural and Malay. Information from such surveys may be useful for planning and organization of medical services.

The mean level of serum IgE in Nigerian blood donors is significantly higher than those in expatriates living in Nigeria and in Swiss blood donors. The examination of serum IgE levels (by the radioactive single radial diffusion technique) in Nigerian patients with different diseases, in asthmatic children with matched controls in Ghana, and in subjects from malarious and non-malarious areas of Tanzania indicates that high IgE levels in Africans may not be due to malaria, vesical schistosomiasis, or onchocerciasis infections. A marked difference, however, was found between African subjects with positive and negative findings of stool parasites; they had higher and lower mean levels of serum IgE, respectively. It seems that, in an African population where the serum IgE levels are raised for other reasons, a rise in IgE in association with allergic conditions such as asthma may not be apparent.

The case is recounted of a child who was admitted to hospitals several times over a period of 8 years on account of fictitious illnesses invented by his mother. The first occurred when he was 3.5 years old in January 1984. His mother, a nurse, gave a history of intermittent fever for 3 months, loss of appetite and weight. He had been treated with ampicillin, chloramphenicol, and procaine penicillin. No abnormality was detected and his weight at 15.5 kg was appropriate for his age. No fever was recorded throughout 2 weeks in hospital, but he was given chloroquine for possible malaria and then discharged. At follow-up 6 months later, the mother complained of his wheezing. On examination he was normal and had gained 3.8 kg since discharge. The possibility of vernal conjunctivitis plus asthma was entertained and he was then placed on ketotiphen prophylaxis. There was an uneventful follow-up for 6 months. 5 years later in March 1990, his mother related that he had been treated from 22 January 1988 to 21 November 1989 for tuberculosis with streptomycin, isoniazid, rifampicin, and ethambutol. He was also treated with digoxin and Esidrex-K for suspected rheumatic carditis, after which at the University Teaching Hospital, Enugu, he was investigated from 11 April 1989 to 10 August 1989 and found to be normal. One year later in August 1991 she went to one of the authors complaining about polydypsia, polyphagia, and polyuria. Examination had revealed nothing of note. A clinical assessment for diabetes mellitus found the urine specific gravity persistently at 1.010. He was therefore put on carbamazepine (Tegretol) 100 mg t.i.d. After review by a pediatric nephrologist, the child was declared normal. During this visit, the mother and child were interviewed separately. He believed he was ill because his mother said so. A diagnosis of Munchausen syndrome by proxy was made. The mother was referred back to her doctor to arrange for psychiatric care. In Munchausen syndrome, patients fabricate a variety of symptoms and evidence of illness that have no organic basis. Munchausen syndrome by proxy is a form of child abuse, difficult to diagnose, that could result in death. It is more prevalent in affluent countries with sophisticated medical facilities. Its rarity in developing countries may contribute to the difficulty of detection.

Monoclonal antibodies (mAb) have revolutionised many areas of medicine, particularly research and diagnostics. Murine, human and humanized mAb have all been developed. The most important clinical applications to date have been in the fields of transplantation and oncology. Experimental and limited clinical trials suggest mAb are emerging as a new therapeutic strategy in the critically ill. Antibodies against a variety of bacteria or their products are potentially useful in gram-positive and gram-negative shock. Anti-cytokine and anti-neutrophil adhesion molecule mAb may be effective not only in septic shock but also in other conditions associated with acute inflammation and cytokine release, e.g., acid aspiration, ischaemia/reperfusion injury (myocardial infarction, haemorrhagic shock, aortic aneurysm repair). Antibodies inhibiting neutrophil adhesion may also be efficacious in asthma, pulmonary fibrosis, meningitis and cerebral malaria. The use of these and other mAb in intensive care is an exciting prospect and future clinical studies will determine the extent of their role in the management of the critically ill.

Polymorphonuclear leukocytes are armed with an impressive arsenal of bactericidal agents that allow these cells to play a vital role in host defense against invading pathogens. However, these same agents can produce extensive cellular damage in host tissues when leukocytes are activated during inflammatory conditions. Recognition of this fact, when coupled with the observation that leukocyte adhesion to post-capillary venules is a critical first step in the inflammatory process, has led to the development of the concept that inhibition of neutrophil-endothelial cell adhesion (NECA) may represent a novel therapeutic strategy for the prevention of leukocyte-dependent injury in inflammatory conditions. Indeed, pharmacological or immunologic inhibition of NECA reduces cellular injury, dysfunction, and necrosis induced by ischemia/reperfusion, circulatory shock and resuscitation, organ transplantation, cardiopulmonary bypass, frostbite, and thermal trauma. NECA also appears to play an important role in the pathobiology of airway inflammation and asthma, pulmonary oxygen toxicity, arthritis, bacterial meningitis, and cerebral malaria. The aim of this review is to summarize the evidence implicating NECA in the pathogenesis of these inflammatory conditions.

Considerable success is now being achieved in defining genetic susceptibility loci in polygenic disease. In particular, new susceptibility loci have been identified in hypertension, type I and type II diabetes, asthma and malaria infection. The approaches and tools for mapping such susceptibility determinants are becoming more clearly defined and the identification of further susceptibility genes is likely to be in demand in the near future.

Following the establishment of university departments of pediatrics after World War II, national pediatric associations were formed in several countries (in Korea in 1945 and in Nepal in 1981). In Papua New Guinea, the Papuan Medical College began in 1959, and a university department of pediatrics was established in 1974. The population of Papua New Guinea is growing at a rate of 2.3% a year, and less than 70% of women receive prenatal care. Only 40% of deliveries are done under medical supervision. Most of child health problems are associated with malnutrition, pneumonia, gastroenteritis, malaria, meningitis, and tuberculosis. Nonetheless, the infant mortality rate (IMR) dropped from 134/1000 in 1971 to 72/1000 in 1980, and to 60/1000 in 1991. In Nepal, improved child health is a national priority, because the IMR is 129/1000 live births, the under-five mortality rate is 200/1000 live births, life expectancy is 52 years, and adult literacy rates are 39% for males and 12% for females. Nurses receive graduate pediatric training, and there is a postgraduate Diploma in Child Health. In Thailand, supervision of births increased from 33.7% in 1980 to 64.8% in 1988; the IMR dropped from 54.8/1000 live births in 1980 to 42/1000 in 1988; and malnutrition in under-fives dropped from 35.6% in 1980 to 28.5% in 1988. However, 85% of children live in rural communities, and rapid urbanization has resulted in overcrowding, with infectious and parasitic diseases, and high maternal malnutrition. Industrialization profoundly affected child health indices. In Korea the IMR was only 12.5/1000 in 1987, life expectancy was 67 years for males and 75 years for females. In Japan, the IMR dropped from 124/1000 in 1930 to 5.2/1000 in 1986; and maternal mortality declined from 176/100,000 live births in 1950 to 10.8 in 1989. Life expectancy increased from 59.6 years for males and 63 years for females in 1950 to 75.5 years and 81.3 years in 1988, respectively. In Australia, children's hospitals mostly treat asthma, congenital anomalies, and leukemia. Pediatric postgraduate education programs had been developed by the 1980's in most countries. The 7th Asian Congress of Pediatrics was held in Perth, Australia, in May 1991, focusing on priorities of child health.

The serum levels of three major granulocyte proteins were measured in patients with onchocerciasis, bancroftian filariasis and intestinal schistosomiasis and compared to controls from patients with malaria, Africans living in areas not endemic for these infections and healthy Germans. The investigation comprised the determination of the eosinophil granule proteins eosinophil cationic protein (ECP) and eosinophil-derived neurotoxin (EDN/EPX), and the neutrophil/monocyte granule protein myeloperoxidase (MPO). ECP and EDN/EPX levels were found elevated only in the three helminth infections that are associated with eosinophilia, while MPO was found elevated in all tested disease groups. The levels of eosinophil granule proteins observed in the helminth diseases by far exceeded those described for bronchial asthma and atopic dermatitis. ECP, EDN/EPX and MPO serum levels reflect the ongoing disease and are related to functional activity of the respective leukopoetic system. ECP and EDN/EPX appear to be markers of the eosinophil effector system and MPO a marker of the neutrophil and/or monocyte/macrophage effector system. Significantly higher ECP levels in chronic hyperreactive onchodermatitis (sowda) versus generalized onchocerciasis seem to reflect an augmented degree of antigenic stimulation, eosinophil activation and eosinophil turnover rates, indicating a more active mechanism of parasite clearance in sowda patients.

The production of pro-inflammatory cytokines, such as interleukins 1 and 6 and tumour necrosis factors, occurs rapidly following trauma or invasion of the body by pathogenic organisms. The cytokines mediate the wide range of symptoms associated with trauma and infection, such as fever, anorexia, tissue wasting, acute phase protein production and immunomodulation. In part, the symptoms result from a co-ordinated response, in which the immune system is activated and nutrients released, from endogenous sources, to provide substrate for the immune system. Although the cytokine mediated response is an essential part of the response to trauma and infection, excessive production of pro-inflammatory cytokines, or production of cytokines in the wrong biological context, are associated with mortality and pathology in a wide range of diseases, such as malaria, sepsis, rheumatoid arthritis, inflammatory bowel disease, cancer and AIDS. Cytokine biology can be modulated by antiinflammatory drugs, recombinant cytokine receptor antagonists and nutrients. Among the nutrients, fats have a large potential for modulating cytokine biology. A number of trials have demonstrated the anti-inflammatory effects of fish oils, which are rich in n-3 polyunsaturated fatty acids, in rheumatoid arthritis, inflammatory bowel disease, psoriasis and asthma. Animal studies, conducted by ourselves and others, indicate that a range of fats can modulate pro-inflammatory cytokine production and actions. In summary fats rich in n-6 polyunsaturated fatty acids enhance IL1 production and tissue responsiveness to cytokines, fats rich in n-3 polyunsaturated fatty acids have the opposite effect, monounsaturated fatty acids decrease tissue responsiveness to cytokines and IL6 production is enhanced by total unsaturated fatty acid intake. There are a large number of potential cellular mechanisms which may mediate the effects observed. The majority relate to the ability of fats to alter the composition of membrane phospholipids. As a consequence of alterations in phospholipid composition, membrane fluidity may change, altering binding of cytokines to receptors and G protein activity. The nature of substrate for various signalling pathways associated with cytokine production and actions may also be changed. Consequently, alterations in eicosanoid production and activation of protein kinase C may occur. We have examined a number of these potential mechanisms in peritoneal macrophages of rats fed fats with a wide range of fatty acid composition. We have found that the total C18:2 and 20:4 diacyl species of phosphatidylethanolamine in peritoneal macrophages relates in a positive curvilinear fashion with dietary linoleic acid intake; that TNF induced IL1 and IL6 production relate in a positive curvilinear fashion to linoleic acid intake; that leukotriene B4 production relates positively with dietary linoleic acid intake over a range of moderate intakes and is suppressed at high intakes, while PGE2 production is enhanced. There was no clear relationship between linoleic acid intake and membrane fluidity, however fluidity was influenced in a complex manner by the type of fat in the diet, the period over which the fat was fed and the presence of absence of TNF stimulation. None of the proposed mechanisms, acting alone, can explain the positive effect of dietary linoleic acid intake on pro-inflammatory cytokine production. However each may be involved, in part, in the modulatory effects observed.
