A sudden increase in Salmonella gastroenteritis affecting infants and children in Hong Kong in 1971 prompted a clinical review of 200 such patients seen over a 6 year period. It showed unprecedented prevalence of Salmonella johannesburg infections and unusually protracted diarrhoea. Only 3.5 per cent of patients were breast fed. Factors causing this chronicity are discussed. All 8 fatal cases were under 7 1/2 months old, with protracted diarrhoea starting within 1 month after birth in 7. The invasiveness of Salmonella johannesburg is low although its infectivity high. Bacteraemia occurred in only 1 patient and focal infections other than gastroenteritis in none. Antibiotics did not improve diarrhoea nor eliminate faecal excretion in the majority of those treated. Prolonged and intermittent faecal excretion of Salmonella was common. Nineteen per cent of patients acquired diarrhoea in hospital; some after a course of antibiotics given for other infections. Experience from this series does not recommend administration of antibiotics to patients with uncomplicated Salmonella johannesburg gastroenteritis. As chronicity of diarrhoea seemed to be the major prognostic factor with regard to mortality and morbidity in this series, further search for causes and control measures of this chronicity is required.

A study was conducted among 234 Bangladeshi children to determine LM (lactose malabsorption) and its relation with age, history of diarrhea, nutrition, and breastfeeding. LM was determined by using BHT (breath hydrogen test) which showed similar results to a modified lactose tolerance test conducted in hospitals. BHT results indicated that 80% of the children over 36 months had LM while all infants less than 6 months absorbed lactose completely. With recent incidences of diarrhea and acute malnutrition the rates of LM increased. In addition, children who were still breastfeeding had a lower rate of LM than weaned children perhaps since breastfed children suffer less from gastroenteritis and diarrhea or because some component of breast milk protects against LM. The United Nation's Protein Advisory Group encourages milk consumption but other reports cite increased mortality rates and slower recovery when malnourished children were supplied lactose-containing milk. It is suggested that milk be distributed in low doses in areas where there are high LM rates.

Analysis of nearly 90 commercial "clear" fluids, including soups, juices, fruit-flavoured drinks and ices, carbonated beverages and gelatins, showed a range of 0.1 to 251 mmol of sodium and 0.0 to 65 mmol of potassium per litre; the osmolality ranged from 246 to more than 2000 mOsm/kg of water. Knowledge of these values is useful in the home or hospital management of patients for whom control of fluid and electrolyte intake is indicated. The results of the analyses are presented in tabular form for use by physicians and nutritionists when counselling patients to ingest clear-type fluids for various illnesses. Examples are given using these data to show how clear-fluid therapy can be tailored in one such illness--gastroenteritis (infectious diarrhea).

Two dogs kenneled at a commercial establishment died of a disease manifested as severe hemorrhagic diarrhea. Histopathologic findings in both dogs bore a striking resemblance to those typical of feline infectious enteritis. Viral particles resembling members of the Parvoviridae family were observed in the contents of the small intestine of one of the dogs. The disease was similar to the recently recognized canine gastroenteritis associated with a parvovirus-like agent.

In an effort to determine the relation of breast versus bottle feeding to hospitalization for gastroenteritis, children hospitalized for gastroenteritis at the Kaiser-Permanente Medical Center in California were compared with a larger normal population of children discharged from the Center's nursery, for incidence of breast feeding. All infants under 12 months of age admitted to the hospital with acute gastroenteritis between January 1, 1973 and December 31, 1975 were identified. All infants had an acute onset of diarrhea and weight loss, some with vomiting. Variable degrees of clinical dehydration also occurred. 107 infants were admitted during the period of study. The type of feeding--breast or bottle--was obtained from the patients' admission history, nursery records, outpatient clinic charts, or by direct contact with parents. Of the 197 patients admitted with acute gastroenteritis during the study period, only 1 was being breast fed at the time of admission. 40 infants were under 6 months of age. Breast feeding accounted for 28 percent of the infant-months in the 0-6 month age group. The lower than predicted incidence of acute gastroenteritis in the breast fed infants was statistically significant. Although about 1/3 of the bottle fed infants had started breast feeding at birth, all had been switched to the bottle at least 1 month prior to hospitalization. The study data strongly indicate that breast feeding plays a major role in protection against intestinal infections.

This paper focuses on recent advances by the Indonesian Pediatric Gastroenterology in the field of diarrheal diseases: 1) the 'ROSE' system as the principle of treatment of diarrhea. It has been proven to be effective in reducing mortality rate of acute gastroenteritis, particularly cholera. R stands for rehydration, preferably with Ringer's lactate solution. O for Oralyte or oral glucose electrolyte, S for simultaneous rehydration (intravenously and orally), and E for educating parents in oral rehydration. 2) MCT and low lactose-containing formula in low birthweight infants give good to excellent results in improving fat malabsorption, elimination of diarrhea, and increase of body weight. 3) the use of the pediatric Enterotest duodenal capsule to study the upper intestinal microflora. The capsule consists of a number 1 size gelatin capsule (20 mm x 6 mm) containing a silicone rubber bag with an attached fine yarn line 90 cm long. The free end of the line is taped to the cheek and the patient swallows the capsule. After a certain period of time, the line is pulled out and intestinal secretions are scraped from the line and immediately examined under the microscope. Enterotest is particularly useful where radiologic examination is not available. 4) this report is the 1st to document virus particles in fecal specimens from Indonesian children, and suggests that viruses may be important etiological agents in diarrheal diseases in Indonesia, where malnutrition and diarrhea are important health problems.

The faecal flora of 29 healthy infants and young children was compared with that of 49 children of similar age and socio-ecomonic status with acute gastroenteritis. In the healthy children the most common organisms in the faeces were bifidobacteria, veillonellae, enterobacteria and enterodocci with anaerobes outnumbering aerobes. Most members of the noraml faecal flora were present in the diarrhoeal stools, but anaerobes were signigicantly reduced in number and enterobacteria were significantly increased, thereby altering the ratio of anaerobes to aerobes. The alterations in the flora were not related to the nature of the aetiological agent or to the severity of the diarrhoea. The changes appeared to be a direct result of the altered colonic environment produced by the diarrhoeal state. In 13 of the 28 patients from whom bacterial pathogens were isolated, the pathogens were the predominant faecal organsims.

An analysis of data on Salmonella infection treated at the Children's Hospital "La Fe", in Valencia, from 1974--75 is presentd. A patient population of 211 selected cases were divided into two groups: Gastroenteritis (GEC), 155 cases, and typhoid-paratyphoid fever (T-P F), 56 cases. Hospitalization was required in 79% of the cases. The following parameter were studied: Locality and district of origin with respect to residence, conditions of hygiene, size of family: age, sex, seasonal incidence, previous time of illness, presenting symptoms and physical sings and complementary studies. The following conclusions were obtained: Salmonella infection are and endemic problem in Valencia. Their incidence is maximal during the months of June to October. Epidemiological environment was positive in 15% of the cases. Higher morbidity in children less than two years of age. Most frequent presenting symptoms: Diarrhea, fever and vomiting as often in GEC as in T-P F. In 38.7% of GEC cases, the diarrhea was bloody; 21.9% of GEC cases began with fever. Salmonella paratyphi B was the agent most frequently responsible. Data concerning sex, family size, conditions of hygiene and white blood cells offer little discriminatory information. Results obtained are concordant with those described in the literature.

To understand mechanisms of viral diarrhea further, we studied ileal ion transport in vitro in relation to mucosal changes and epithelial differentiation in transmissible gastroenteritis in piglets, an invasive viral enteritis thought to involve mainly proximal intestine. In infected pigs, at the height of diarrhea, short-circuited ileal epithelium failed actively to transport Na+ and Cl-, and there was a defect of glucose-mediated Na+ transport. The Cl- secretory response to theophylline remained intact. Conductance measurements indicate that paracellular permeability may be reduced and transcellular transport may be altered. A mucosal lesion was observed at the time of the transport changes, characterized by villus blunting, crypt hyperplasia, and immature crypt-type enterocytes on the villus epithelium, deficient in disaccharidase and (Na+, K+)ATPase activity but rich in thymidine kinase. Consideration of the major determinants of diarrhea in this invasive enteritis must take into account not only altered mucosal function and differentiation but also the extent of intestinal involvement, including the ileum, a major site of fluid absorption in the intestine.

The histopathological changes that occur in the jejunal mucosa of humans infected with the Norwalk or Hawaii agent of acute infectious nonbacterial gastroenteritis ("viral" gastroenteritis) have ben well characterized. The pathogenesis of diarrhea in this syndrome remains unknown; however, recent reports have suggested a possible role for the adenylate cyclase system. In this combined paper, two groups of investigators working independently and employing slightly different techniques report that: (1) there is marked interindividual variation in the apparent specific activity of adenylate cyclase in human jejunal biopsy tissue; (2) such variation can be minimized by expressing enzyme activity as a fraction of maximal that can be stimulated by 10(-2) M sodium fluoride; and (3) adenylate cyclase activity in jejunal mucosa is not increased during diarrhea or illness in human viral gastroenteritis, therefore suggesting no role for the adenylate cyclase system in the pathogenesis of diarrhea in this common clinical entity.
