In recent years, Aeromonas species has been reported to cause extraintestinal infections with a growing frequency. Meningitis due to Aeromonas species is, however, a rare entity. We report a case of aeromonas meningitis in a 54-year-old man with a history of chronic alcoholic liver disease who, after an episode of gastroenteritis, developed an acute clinical picture characteristic of meningitis with septic shock and ecthyma gangrenosum. Aeromonas veronii (biogroup sobria) was isolated from cultures of blood as well as from cultures of stool, peritoneal fluid, skin lesion, and CSF specimens (obtained by lumbar puncture). Our review of seven additional cases of aeromonas meningitis in the world literature revealed that this condition is generally secondary to metastatic dissemination from primary bacteremia. Aeromonas meningitis, which may or may not be preceded by gastroenteritis, presents clinically as bacterial meningitis, although the presence of skin lesions may increase suspicion of the diagnosis. Third-generation cephalosporins are probably the therapy of choice for patients with aeromonas meningitis.

The literature contains reports documenting a foodborne etiology for bacterial infections caused by Salmonella spp, Listeria monocytogenes, Campylobacter jejuni, and Vibrio spp in individuals with the human immunodeficiency virus (HIV). The incidence of these infections and the life-threatening complications that result are elevated in people with HIV infection. We present practical recommendations to prevent foodborne illnesses and the resulting complications, including gastroenteritis, bacteremia, meningitis, and death. We suggest that patients with HIV infection be counseled to avoid foods at high risk for harboring bacterial pathogens and to use careful sanitary practices in food preparation.

Interleukin-8 (IL-8) elaborated by monocytes and endothelial cells is a cytokine which is responsible for adhesion of leucocytes to vascular endothelium and migration of neutrophils into the cerebrospinal fluid (CSF) from the intravascular space. The inflammation in meningitis is elicited by the cytokine release from leucocytes which encounter micro-organisms in the arachnoid or subarachnoid space. In bacterial meningitis, tumour necrosis factor (TNF), IL-1 and IL-6 are produced vigorously, and initiate and augment the inflammation in the central nervous system. In this study, utilizing a quantitative immunometric sandwich enzyme immunoassay, the concentration of IL-8 was investigated in the CSF of patients with bacterial meningitis, patients with aseptic meningitis, and patients with gastroenteritis who served as controls. The IL-8 concentration was markedly higher in the CSF of patients with bacterial meningitis (224 +/- 2.57 pg/ml; mean +/- SD) than in the CSF of patients with aseptic meningitis (less than 30 pg/ml). The IL-8 level in the CSF of patients with aseptic meningitis did not differ from that in the CSF of the patients with gastroenteritis (less than 30 pg/ml). The augmented production of IL-8 in CSF may account for the inflammation in bacterial meningitis being more severe than that in aseptic meningitis.

The role of the genus Edwardsiella in human illness is reviewed. Of the three recognized species, only Edwardsiella tarda has been demonstrated to be pathogenic for humans. Chief infections associated with this species include bacterial gastroenteritis, wound infections such as cellulitis or gas gangrene associated with trauma to mucosal surfaces, and systemic disease such as septicemia, meningitis, cholecystitis, and osteomyelitis. Risk factors that are associated with E. tarda infections include exposure to aquatic environments or exotic animals (e.g., reptiles or amphibia), preexisting liver disease, conditions leading to iron overload, and dietary habits (e.g., raw fish ingestion). Although studies indicate that this bacterium is susceptible to most commonly prescribed antibiotics, fatal gastrointestinal and extraintestinal infections have been described.

Infections are the leading cause of childhood morbidity and mortality in developing countries. Bronchopneumonia, meningitis and gastroenteritis are the commonest fatal infections encountered in Ibadan. Tuberculous lymphadenitis, bronchopneumonia and meningitis are other frequent causes of death. The predominant sequela of measles is respiratory tract infection. Another important cause of childhood mortality is cerebral malaria. In half of the cases of tetanus no obvious portal of entry can be found. It is advocated that the implementation of immunization schedules should be vigorously pursued to curtail childhood mortality resulting from infection.

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.

There is considerable mortality in sub-Saharan Africa relative to other regions in the world. No country in Africa, however, has a system of vital registration capable of providing reliable national data on mortality. Accurate information on the causes of adult mortality is therefore very limited. This lack of knowledge is becoming especially important in light of the impact HIV infection and AIDS are having in many sub-Saharan African countries. The authors documented the pattern of adult medical deaths in Queen Elizabeth Central Hospital, Blantyre, Malawi between April 1992 and March 1993. Their findings were then compared with data on mortality collected from the same wards in 1973, before the AIDS pandemic. Tuberculosis (TB) and AIDS together accounted for 49% of all medical deaths in 1992-93, with 82% of deaths occurring among individuals aged 13-49 years. TB, AIDS, gastroenteritis, pneumonia, pyogenic meningitis, and septicemia were the most important causes of death. In 1973, TB was responsible for 13% of deaths and there were no deaths due to AIDS. The authors note that the predicted upsurge in the level of AIDS-related mortality in sub-Saharan Africa during the 1990s will have grave consequences for the health sector, as well as for the social and economic fabric of the countries concerned.

Hafnia alvei is a gram-negative bacterium that is rarely isolated from human specimens and is rarely considered to be pathogenic. It has been associated with gastroenteritis, meningitis, bacteremia, pneumonia, nosocomial wound infections, endophthalmitis, and a buttock abscess. We studied 80 H. alvei isolates recovered from 61 patients within a period of 30 months. H. alvei was cultured from sites that included the respiratory tract (n = 38), the gastrointestinal tract (n = 16), and the urogenital tract (n = 12); the organism was found in blood cultures (n = 8), on central venous catheters (n = 3), and on the skin (n = 3). Only 25% of H. alvei isolates were recovered in pure cultures. Fifty-seven (93.4%) of the patients had an underlying illness. H. alvei proved to be the etiologic agent in two episodes of septicemia and in one episode of peritonitis and was probably responsible for septicemia in two other patients and pneumonia in one. All six of these patients recovered after receiving antibiotic treatment and/or standard surgical treatment, when needed. Three of these infections were nosocomial, and three were community acquired. Of the strains of H. alvei tested in our study, 100% were susceptible to netilmicin, ciprofloxacin, and imipenem; 92% were susceptible to piperacillin; 90% were susceptible to co-trimoxazole; and 88% were susceptible to ceftriaxone and ceftazidime. In this study, we found H. alvei to be a rare significant etiologic agent of nosocomial and community-acquired infections.

A prospective case-control study conducted on the north coast of Papua New Guinea in 1993-96 investigated the hypothesis that alpha(+)-thalassemia provides a selective advantage against endemic Plasmodium falciparum. In this geographic area, alpha(+)-thalassemia affects more than 90% of the population. 249 children admitted to Madang Hospital with one or more symptoms of severe malaria (severe anemia, coma, hypoglycemia, acidosis, and hyperlactatemia) were paired with 249 randomly selected healthy age- and sex-matched controls. Also enrolled were 233 children with infections other than malaria, primarily respiratory infections, gastroenteritis, and meningitis. Compared with healthy community controls, the risk of severe malaria was 0.40 (95% confidence interval (CI), 0.22-0.74) in alpha(+)-thalassemia homozygotes and 0.66 (95% CI, 0.37-1.20) in heterozygotes. The lowest odds ratios for alpha(+)-thalassemia homozygotes were recorded in the acidosis and hyperlactatemia subgroups--the two complications most predictive of malaria mortality. Unexpectedly, the risk of hospital admission with infections other than malaria was reduced to a similar degree in homozygous (0.36; 95% CI, 0.22-0.60) and heterozygous (0.63; 95% CI, 0.38-1.07) children. Although the relevant mechanism is unknown, these findings confirm a clear interaction between thalassemia hemoglobinopathy and both malarial and other infections. Given its high frequency and protective effect against malaria and some other infections, alpha(+)-thalassemia is likely to have a major impact on child survival in coastal Papua New Guinea.

This study evaluated the quality of the clinical management of the most common childhood diseases in rural Papua New Guinea: pneumonia, malaria, gastroenteritis, malnutrition, meningitis, and tuberculosis. Study methods included direct observation of the routine management of 384 sick children and evaluation of the clinical knowledge of 124 health workers at health centers, health subcenters, and aid posts. Although protocols are outlined in standard treatment manuals available to all health professionals, the analysis revealed major inadequacies in the quality of history taking, examination, record keeping, diagnosis, and treatment. Overall, 0-3 history questions were asked in 48% of all physician-patient observations and 0-1 examination procedures were performed in 41%. Weight was taken In only one-third of cases. Screening for severe diseases such as pneumonia, tuberculosis, meningitis, severe dehydration, and weight loss was lacking. History taking and examination performance levels were positively associated with the professional training of the health worker. The child's guardian was told about what was wrong with the child in 23% of cases, treatment instructions were given in 44%, preventive advice was given in 21%, and instructions on when to return the child to the facility were given in 38% of cases. A specific diagnosis was recorded in only 17% of child health record books. In terms of treatment, an overuse of injectable penicillin was observed. Recommended are community education on the importance of early presentation at a health facility, continuing education for rural health workers, and a comprehensive approach to supervision that periodically assesses logistics and management needs.
