Severe protein-energy undernutrition is a frequent finding among chronically ill patients. Its causes are anorexia, hypermetabolism, and malabsorption. Adverse consequences include impaired cell-mediated immunity increased susceptibility to infection, poor wound healing, weakness, and death. Spontaneous oral intake is inadequate in patients with this disorder, and therapeutic maintenance or repletion alimentation is needed. Enteral hyperalimentation is the method of choice, if tolerated. A successful treatment program usually requires a small-bore, flexible nasoenteral tube, appropriate feeding solution, and constant flow delivery of nutrient. If only partial dietary requirements are tolerated enterally, peripheral intravenous nutrient solutions can often supply the deficit. Although not suitable for all patients, enteral hyperalimentation is more physiologic, safer, easier, and more economical than central venous hyperalimentation. It would be well tolerated by many patients who now receive nutritional repletion by the latter method.

Zinc is an essential trace element whose malabsorption in early childhood may result in a skin disorder known as acrodermatitis enteropathica. Cutaneous lesions typical of acrodermatitis enteropathica have been described during total parenteral nutrition on zinc-deficient intravenous solutions in both adults and children. This condition has been named the "acute zinc depletion syndrome." A case is described in which a patient, despite a zinc intake of double the daily requirement, manifested the acute zinc depletion syndrome during therapy with combined liquid diet plus parenteral hyperalimentation. Predisposing factors in this individual included a short bowel syndrome and a large oral load of calcium lactate. Zinc metabolism is reviewed with attention to alterations in disease and during hyperalimentation. The clinical manifestations, predisposing factors, therapy and prevention of the acute zinc depletion syndrome are discussed.

Eighty infants have been treated for neonatal necrotising enterocolitis within a period of five years. Twenty-five per cent developed strictures of the small or large intestine. Four cases of atresia including two with multiple cyst formation were seen. Four patients developed severe malabsorption requiring hyperalimentation with slow recovery of small bowel function in two survivors. The radiological features of these complications is illustrated and the role of radiology in the management of these patients is discussed.

Hypophosphatemia is common in hospitalized patients and occurs under a variety of circumstances other than parathyroid hormone excess. Charts of 100 inpatients with hypophosphatemia were reviewed and the patients divided into five groups on the basis of serum phosphate level: 18, 2.1 to 2.4 mg/dL; 49, 1.6 to 2.0 mg/dL; 20, 1.1 to 1.5 mg/dL; 12, 0.6 to 1.0 mg/dL; 1, 0.1 to 0.5 mg/dL. The effect of glucose ingestion on serum phosphate level was shown in one normal patient. Whenever carbohydrate was administered intravenously (45 cases), this was considered the primary cause of the hypophosphatemia. Other causes were as follows: diuretics, hyperalimentation, alcoholism, respiratory alkalosis, dialysis, insulin, corticosteroids, diabetic ketoacidosis, vomiting, phosphate-binding antacid, Gram-negative sepsis, primary hyperparathyroidism, saline, epinephrine, gastrointestinal malabsorption, and unknown. Hypophosphatemia in hospitalized patients may have multiple causes.

Of 59 infants with jejunoileal atresia, seven presented with absence of mesentery, the main superior mesenteric artery ceasing to exist beyond the origin of the right colic or ileocolic artery, and a helical ileum. This distinctive form of jejunal atresia has been recognized with increasing frequency in recent years. Distal to the atresia, the small bowel receives its blood supply retrograde from an artery derived from the ileocolic or right colic arcades, and the ileum coils around its nutrient artery in an "apple peel" or "Christmas tree" deformity. The first three patients in this report died. The lastion, but they recovered as their malabsorption gradually disappeared. The treatment includes resection of the dilated bowel, as in other atresias. Resection of part of the distal bowel may be required for additional atresias or for poor vascularity with questionable viability. Postoperative malabsorption generally requires intravenous hyperalimentation.

An anomaly of the position of the midgut in a pregnant woman predisposes to volvulus. Vascular repair, despite the abdominal catastrophe, sometimes allows parts of the intestine to be saved. A case of volvulus in a pregnant woman is described. At operation, 18 hours after onset, two anomalies were found: reverse rotation of the midgut and an anomaly of the collecting system of the superior mesenteric vein. Most of the midgut was infarcted. Thrombi were removed from the superior mesenteric vessels, and a portion of the anamalous superior mesenteric vein was reconstructed. All but 3 M. of the small bowel and the entire right colon were resected. Prolonged treatment with parenteral hyperalimentation enabled us to control the appearance of a moderate degree of malabsorption. To our knowledge, no similar case has been reported previously in the literature.

Very frequently in acute and chronic pancreatitis, the surgical treatment is indispensable. The disease itself is accompanied by metabolic disturbances, protein deficiency, hepatic lesion, by diabetes and malabsorption syndrome. Following the laboratory parameters we were able to perform partial or total hyperalimentation, correction of acid-base dis-equilibrium and to obtain the positive nitrogen balance, and in this way keep the patients in optimal conditions pre- and postoperatively.

A patient with acute ischaemia of the abdominal organs after coeliac- and superior mesenteric artery occlusion is reported. Following vascular reconstruction and resection of gangrenous colon and ileum the main early postoperative problem was hepatic failure. A grave malabsorption syndrome developed necessitating periodic i.v. hyperalimentation. The patient showed no improvement of intestinal function and died 5 months postoperatively from peritonitis.

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.

Findings in a 1-month-old male infant with Wolman's disease, a rare autosomal defect characterized by intractable diarrhea and severe malabsorption, are described. Investigations in this case focused on the digestive and absorptive functions of the jejunum using histological, biochemical, and electrophysiological methods. The intestinal villi were found to be distorted and club-shaped as a result of the infiltration of foam cells into the lamina propria of the mucosa. The microvilli of the epithelial cells were found on electron microscopy to be markedly shortened and irregular, and had a severe impairment of disaccharidase activity. Documentation of the loss of the sugar- and amino acid-evoked potential differences in the jejunum confirmed the severity of intestinal malabsorption. These observations indicate that the intestinal damage in Wolman's disease is so severe as virtually to exclude the absorption of any form of enteral nutrition. Despite the administration of i.v. hyperalimentation, the infant died of hepatic failure at the age of 6 months.
