In a clinical study of 32 infants with symptoms from infections with the human reovirus-like agent (R.I.A.) identified by electron microscopy (E.M.) of faecal extracts, a fairly consistent clinical pattern was found in 30 who had a gastroenteritis-like illness. The disease was usually mild, affecting mainly infants less than 2 years and males more commonly than females. The incubation period appeared to be 48-72 hours; and the onset was sudden, often with vomiting in the first 1-2 days of the illness. Loose yellow-green offensive stools without blood or mucus developed after a variable time, and there was often accompanying fever. Severe dehydration and electrolyte inbalance were uncommon; and with standard treatment the illness was uncomplicated, usually lasting 5-8 days. These features resemble those of previously reported winter epidemics of infantile non-bacterial gastroenteritis, and it is suggested that these epidemics were due to R.L.A. 2 infants in whom R.L.A. was identified in the stool did not have a gastroenteritis-like illness although both had protracted diarrhoea.

Transmissible gastroenteritis or TGE is a virus diarrhoea which occurs in pigs of all ages and is associated with high mortality rates in the young piglets. Growth of virus in the columnar epithelium of the small intestine causes atrophy of the intestinal villi, malabsorption, watery diarrhoea and dehydration. Faecal excretion of virus usually continues up to fourteen days after infection but chronic carriers have been found to occur. TGE is self-limiting on the majority of pig-breeding farms but the virus may persist in particular conditions and an enzootic form of the disease will appear in this case. In typical outbreaks, the diagnosis can usually be based on clinical symptoms. When the disease runs an enzootic course, a clinical diagnosis will be out of the question. TGE should be differentiated from colibacillosis and from another virus diarrhoea, the aetiology of which is not precisely known. A rapid and correct diagnosis may be established by direct fluorescent antibody studies of frozen sections of the small intestine in infected piglets. When sows have been spontaneously infected, their offspring will be protected by lactogenic immunity. The presence of TGE antibodies of IgA class in the milk is required to ensure complete immunity of the piglets lasting for weeks on end. Intramuscular inoculation of a commercially available vaccine in sows will only stimulate the production of antibodies of the IgG class in the milk. These antibodies will merely afford short-lived immunity. The vaccine cannot prevent symptoms of disease from appearing in piglets following infection with virulent TGE virus but it does reduce mortality

Between January, 1974, and June, 1975, infection with a human reovirus-like agent was detected in 47% of 152 infants and children hospitalized with acute gastroenteritis. Certain epidemiologic, clinical, and laboratory findings appear to be helpful in distinguishing gastroenteritis due to HRVLA from other causes in those children sick enough to require hospitalization. Age: 76% of infants and children seven through 12 months of age and 76% of those 13 through 24 months of age had infection with the HRVLA, whereas such infection was found in only 21% of infants under six months of age and 23% of children 25 through 60 months of age. Time of Year: 61% of patients studied during the cooler months had HRVLA infection and such infection was not found from June to October. Frequency of vomiting and dehydration: Twice as many patients infected with HRVLA as those who were not had vomiting (92%) and significant dehydration (83%).

In 43 out of 90 children suffering from acute gastroenteritis Rotaviruses could be identified in stool-specimens by electronmicroscopy. Symptoms were watery diarrhoea (100%), vomiting (88%), fever (77%), dehydration (47%) and upper respiratory tract infection (21%). In 3 out of 9 patients liver involvement could be documented. In 29 children i.v.-fluid therapy for 1-2 days was necessary. Only in 1 patient severe diarrhoea persisted for 11 days.

A study of acute gastroenteritis in children was carried out with the aim of establishing the prevalence of human reoviruslike agent (HRLA) and its relation to other enteric pathogens in Israel. The stools of 384 children with acute diarrhea referred to a pediatric emergency service were screened for HRLA by counterimmunoelectroosmorphoresis (CIEOP) and for pathogenic bacteria. Evidence of HRLA infection was found in 65 patients (17%). The highest infection rate prevailed during the cool season (25%), with a peak prevalence (41%) in November, when both the temperature and humidity were low. A very high proportion of HRLA was found in children younger than 36 months and no HRLA infection was observed in those older than nine years. The highest prevalence occurred in infants younger than six months, a situation rarely encountered in other countries. The main clinical features of HRLA infection were fever, vomiting, dehydration, signs of upper respiratory infection and carbohydrate intolerance. Bacterial pathogens accounted for 45% of enteric infections. Shigella species predominated (28%) during the summer season, especially in older children. In 38% of the study group, no etiologic agent could be detected. None of the 50 control subjects showed evidence of viral or bacterial pathogens in stools.

A comparative study was undertaken in Indonesia to assess the effect of antibiotic therapy in the treatment of acute diarrheal disease in infants. 120 children, age 2-60 months, suffering form acute gastroenteritis with varying degrees of dehydration who were treated at the Gadjah Mada University Hospital in Yogyakarta, Indonesia, between August and December 1975, were included in the study. Approximately 1/2 the group was treated with antibiotics; the other 1/2 was not. Both groups received oral rehydration therapy. No significant differences were found between the 2 groups as to duration of the diarrhea and duration of hospitalization. It is concluded that antibiotics are not generally indicated in cases of acute diarrheal disease. The only requirements in treatment seems to be maintenance of the fluid electrolyte balance.

During a 21-month period from April 1974 to February 1976, 948 children with gastroenteritis were studied. Aetiologic agents were identified in 43% of these patients. Isolates were identified as follows: V. cholera El Tor, 273 (67%); Salmonella enteritidis, 64 (16%); enteropathogenic E. coli, 28 (7%); Shigella, 28 (7%); Vibrio (NAG), 9 (2%): and V. parahaemolyticus, 7,2%). Gastroenteritis with dehydration is a serious continuing pediatric problem in Jakarta, constituting 30% of admissions to Sumber Waras hospital. The incidence of both cholera and salmonellosis increased during the past 2 years, as judged by the distribution of enteric bacteria isolated from the rectal swabs of gastroenteritis patients in Sumber Waras hospital.

In infants and children acute dehydration is mainly caused by gastroenteritis with vomiting and diarrhoea, and by feeding failures. Since in the German speaking literature very different therapeutic regimens for rehydration are discussed the principles of oral and parenteral treatment are described. The rational therapy is based on the knowledge of physiology and pathophysiology of water and electrolyte metabolism. Therefore a few basic aspects are described, i.e. compartments of body fluids, turnover rates, the balance, types of dehydration, concentration of electrolytes in body fluids and their relevance to dehydration. Special problems exist in the treatment of hypertonic dehydration. In order to avoid cerebral edema the rehydration should not be attempted quickly with very hypotonic salt solutions, but should be performed with a 1/2--1/3 isotonic Ringer-lactate solution and early begin of potassium substitution over a period of 48 h.

Gastroenteritis due to Salmonella enteritis is an endemic disease in our region, extraintestinal manifestations however are rare. We report a 8 years old girl who presented after 4 days of an unspecific diarrheal disease with watery liquid stools, vomiting, abdominal cramps, fever above 39 Grad C and symptoms and signs of an acute abdominal emergency. Mid abdominal laparotomy disclosed a cholecystitis with reactive peritonitis. Cultures of bile showed Salmonella group B as the causative organism. Cholecystectomy was performed, postoperatively Gentamycin later Chloramphenicol was administered. The postoperative course was unremarkable. Cholecystitis is a rare disease in pediatrics. Gallstones don't seem to play a roll in the etiology unlike in adults. It usually follow serious systemic infections or postoperatively after unrelated abdominal surgery due to overgrowth of the biliary system and organisms contaminating the upper gastrointestinal tract (biliary stasis, dehydration). Salmonella enteritidis as a cause of a cholecystitis is a rare event.

The feeding habits of 70 infants under 6 months old hospitalized with acute gastroenteritis were studied to determine whether current efforts to discourage high-solute feeding were having an effect on the incidence of hypernatremic dehydration. Fifteen infants (21%) were fed modified (low-solute) milks and 55 (79%) unmodified (high-solute) milks. Of 47 infants under 3 months old, 15 (32%) had commenced mixed feeding. Plasma sodium level was estimated in 60 infants. Mean values in the modified and unmodified groups were the same, at 137 mEq/liter. Only one infant was hypernatremic (sodium level, 152 m/eq/liter). Osmolalities of 65 samples of milk were measured to provide a measure of milk concentration. Only ten (16%) exceeded by more than 25% that recommended by the manufacturers. Twenty-two (34%) were less than 75% of the recommended concentrations. These improved feeding practices have probably contributed largely to the very low incidence of hypernatremia by preventing dangerously high solute intakes at a time of particular vulnerability.
