This paper briefly reviews new knowledge about the causes, consequences and control of gastro-enteritis. Various recently discovered viral and bacterial causes of gastro-enteritis are discussed and the possible role of prolonged gut infection in causing malabsorption and thus malnutrition, considered. The revival of interest in prevention by improved water supplies is discussed and the need to critically evaluate the relative importance of the quality and quantity of a water supply stressed. Some newer regimes for treating acute and chronic infections are also discussed.

Forty newborns bearing several gastrointestinal conditions (congenital malformations, intestinal bypass, postinflammatory obstruction, malabsorption and enteritis) were treated with long-term integral parenteral nutrition. A solution made up of synthetic aminoacids, emulsion of lipids, glucose, electrolytes, vitamins, plasma and whole blood was perfused through a catheter introduced into central or peripheral veins. Temporal glucosuria and anemia were observed in some cases. In all but three cases urinary alpha amino nitrogen was normal. In some infected patients leucocytosis or leucopenia was found. After treatment, all patients showed adequate nutritional conditions, manifested by increase in body weight and healing of damaged tissues.

A 45-year-old woman with intestinal malabsorption due to eosinophilic gastro-enteritis was found to have markedly fluctuating total serum IgE levels with a positive intradermal skin test and a positive radio-allergosorbent test to milk antigen. No organ-specific or non-organ-specific auto-antibodies were detected in the patient's serum, and her complement profile was normal. Low doses of disodium cromoglycate failed to improve intestinal absorption, whereas a 16-day course of a corticosteroid, beclomethasone dipropionate 3 mg daily, improved D-xylose and carotene absorption without suppressing the hypothalamic-pituitary-adrenal axis.

Clinical, biochemical, and gastroenterological data have been examined im 48 patients in two age groups, one under 12 months of age, the other between 12 and 30 months with persistent post-enteritis diarrhoea. In these patients, the illness consisted of chronic diarrhoea which followed acute enteritis. It brought about a mild malabsorption syndrome with impairment of growth, particularly in infants under one year of age. Chronic inflammation with mucosal damage due to alteration of the intestinal microflora by inappropriate diets and therapy seemed to be the cause of persistent diarrhoea in these patients.

A suicidal 67-year-old woman with manic-depressive psychosis took an overdose of asprin, amitriptyline and diazepam. The initial effects were pyrexia, tachycardia, hyperpnea, metabolic acidosis, electrocardiographic changes, hypoprothrombinemia, gastritis, and pancreatitis. Four to six weeks later, she was examined because of persistent abdominal pain with mausea, anorexia anemia, and possibly a malabsorption syndrome. An exploratory laparotomy was performed. The surgeon found several previous adhesions, a small intestinal volvulus, and a nodular pancreas. This suggested previous perforation of the small bowel from enteritis, causing a "blind-loop" syndrone. The invilved section of the small bowel was resected. With appropriate treatment, the patient is well three months after operation.

A circular was sent to eight clinics and 36 cases of children with extensive resections of the small intestine are reported. The reasons for the resections of the intestine were atresia and stenosis in the largest number of cases, then volvulus and lastly necrotizing enteritis. The residual intestine was measured with the measuring tape in only eight cases. The method of measurement in the other cases was not given. Surgery was unilateral in 26 cases and bilateral in ten. Surgical measures to slow passage were not used. The most frequent single causes of death were sepsis or pulmonary complications. The cause of death was a true malabsorption in only two cases. The main difficulties in the postoperative phase are ensuring adequate parenteral uptake of calories and the complications due to cava-catheter sepsis.

Gastrointestinal injury is known to occur following radiation therapy of tumors in the abdominopelvic compartment. Chronic radiation changes may be associated with diarrhea and malabsorption. A patient with transitional cell carcinoma of the bladder developed diarrhea following radiotherapy and was treated symptomatically for nine years with the assumption that the diarrhea was secondary to radiation enteritis. Further evaluation including endoscopic cholangiopancreatography, revealed pancreatic insufficiency with steatorrhea as the probable cause of the patient's diarrhea. Although temporally related to radiation therapy, the etiology of his pancreatic insufficiency remains speculative. All patients developing diarrhea and/or malabsorption following radiotherapy should be evaluated thoroughly for treatable causes.

Iron status, iron absorption, and intestinal blood loss were studied in 199 children undergoing diagnostic evaluation for suspected malabsorption. Evaluation of iron status included hematological indices, serum ferritin, and transferrin saturation. Iron absorption was assessed by the increment of serum iron after an oral iron load. Iron deficiency was common among patients affected by malabsorptive states, such as celiac disease (84%), cow's milk intolerance (76%), Crohn's disease (72%), and giardiasis (64%), whereas it was less common among patients with postinfectious enteritis (41%) and chronic nonspecific diarrhea (11%). Intestinal blood loss was seen only in patients with Crohn's disease and cow's milk intolerance, irrespective of iron nutritional status. On the other hand, iron malabsorption was very common, affecting 85-95% of the iron-deficient patients in all diagnostic groups, except in chronic nonspecific diarrhea. Iron malabsorption was less common among patients with adequate iron nutritional status than in those with iron deficiency. Iron malabsorption appears to play a major role in the pathogenesis of iron deficiency in patients with malabsorption. The iron absorption test shows greater sensitivity as a screening test for upper intestinal malabsorption than the D-xylose absorption test.

Deterioration in nutritional status occurs late in the progress of cancers at certain sites, but at all stages in patients with gastrointestinal cancer. Weight loss with decrease in body fat and muscle wastage, occurs to a varying degree. Superficially, the clinical condition resembles simple food deprivation. However, the derangements in metabolism are often and some patients show an elevated resting energy expenditure, disturbances of carbohydrate, fat and protein metabolism and generally, a failure to adapt to reduced food intake, which is characteristic of cachexia. Cancer cachexia then becomes characterized by signs of marked negative energy and protein balance, including hypoalbuminemia, weight loss, and anemia. On the other hand, toxohormone extracted from tumor tissues was considered as the main cause to produce cancer cachexia. However, it has become clearer that cytokines, e.g. cachectin/TNF, IL-1, LT and IFN gamma play an important role to produce cachexia. Patients who are malnourished have an incidence of postoperative complications double that seen in adequately nourished patients. The effectiveness of cancer-chemotherapy is also different in nutritional status of patients. Although in patients requiring hyperalimentation, enteral nutritional support may feasible and enteral feeding has a distinct metabolic advantage compared with parenteral feeding, there is a definite role for total parenteral nutrition in patients who have severe chronic radiation enteritis, side effect of chemotherapy, weight loss and malabsorption. Tentative weight gain and correction of hypoalbuminemia without improving patient survival may be expected by this intravenous hyperalimentation.

Home parenteral nutrition (HPN) was used in 14 cancer patients within a 4-yr and 4-month period. Indications included severe malabsorption, short bowel syndrome, radiation enteritis, and malignancies. The mean duration of HPN was 184 days (range: 21-706 days). HPN duration for patients with benign causes (BP) was longer [427 days (range: 176-706 days)] than for cancer-related patients (CP) [49 days (range: 21-121 days)]. The mean catheter life spans to date for BP and CP have been 596 days (range: 187-1173 days) and 127 days (range: 73-278 days), respectively. Serious catheter problems occurred 4 times in BP with the external catheter. Metabolic complications with clinical symptoms occurred in one BP who had short bowel syndrome. We followed with an evaluation of the quality of life of HPN patients. Three in 14 cases returned to work, two of them part time, and two others did most of the housekeeping, but 9 remained at home receiving only outpatient treatment. Some physical distress was recorded in all but one case. We concluded that HPN for cancer patients is a relatively safe, effective means of improving and maintaining the nutritional status, and it can reduce the length of hospitalization. We attempted to evaluate whether these patients were able to achieve a meaningful and satisfactory social and familial life. Our study was not sufficient to assess the psychological and social problems. We should establish criteria for quality of life to evaluate overall satisfaction with conditions of life under HPN.
