Bulimia is an episodic compulsive urge to overeat often followed by recurrent attempts to lose weight by self-induced vomiting. Seven young women with this eating disorder and associated benign bilateral painless parotid enlargement are described. The glandular swelling was generally intermittent, with parotid enlargement usually developing 2 to 6 days after a binge overeating episode had stopped. Several had hypokalemic alkalosis and a moderate elevation in serum amylase levels. None had clinical evidence of pancreatitis, and a parotid gland biopsy in one patient was normal. The clinician should be alerted to the association of benign parotid enlargement with this syndrome.

The experience of 73 consecutive infants with gastroschisis and omphalocele is reported. The overall survival rate was 80 percent; however, since 1973 the survival rate for ruptured and intact omphaloceles has been 87 percent and 93 percent for gastroschisis. This remarkable reduction in mortality has been attributed primarily to the advent of total parenteral hyperalimentation, but mortality has also decreased due to the use of pediatric respirators which overcome the effects of increased intraabdominal pressure, and the creation of the neonatal intensive care unit where monitoring of these often fragile infants and the presence of specialty personnel assist in their care.

Recent studies suggest that the rate of nutrient transit through the upper gastrointestract may provide cues that are important to the control of food intake. We examined gastrointestinal function in rats with streptozotocin-induced diabetes and related these findings to concomitant changes in food intake. Control and diabetic rats were adapted to one of two isocaloric diets either high in carbohydrate or fat. Control rats ate similar amounts of each diet. In contrast, diabetic animals fed high-carbohydrate diet were hyperphagic, whereas those fed low-carbohydrate diet ate normal amounts of food. Gastric emptying, intestinal mass, disaccharidase activity, and glucose absorption were increased in normophagic diabetic rats fed a low-carbohydrate diet. Feeding diabetic rats high-carbohydrate diet potentiated each of these effects, and food intake was highly correlated with rate of gastric emptying. These and other results indicate that diabetes enhances gastric emptying and intestinal carbohydrate digestion and absorption, even in the absence of hyperphagia. Consequently, the hyperphagia of diabetic rats may be in part a behavioral response to a greatly accelerated clearance of nutrients from the upper gastrointestinal tract that occurs when these animals are fed diets rich in carbohydrate.

Immunoreactive insulin (IRI) concentrations were measured in plasma and cerebrospinal fluid (CSF) of four-month old genetically obese Zucker rats, their heterozygote lean littermates, and age-matched normal-weight Wistar rats. Basal plasma IRI was 201 + 35 microU/ml (means +/- SEM) in the obese animals and was significantly elevated compared to both lean Zucker rats (18 +/- 2.4 microU/ml, P less than 0.001) and Wistar rats (12 +/- 2.4 microU/ml, P less than 0.001). The mean CSF IRI concentration of fasted obese Zucker rats was 1.59 +/- 0.19 microU/ml; this was significantly higher than the CSF IRI level of either fasted Zucker lean rats (0.31 +/- 0.08 microU/ml, P less than 0.001) or Wistar rats (0.34 +/- 0.12 microU/ml, P less than 0.001). Plasma and CSF IRI concentrations were increased in free-feeding as compared with fasted animals. These data provide evidence that endogenous CSF insulin is derived from circulating plasma insulin in the rat and suggest that the hyperphagia and obesity of the Zucker fatty rat are not due to an inability of circulating insulin to gain access to the CSF.

In carcinoma of the esophagus, response to in vivo sensitization with recall antigens and DNCB was markedly depressed with 13% and 16% positivity respectively. Similarly, the number of T-cells was found to be significantly low (24 +/- 14) as compared to normal control (61 +/- 23). Blastogenesis index with PHA was only 1.75 +/- 1.04 in contrast to normal of 6.79 +/- 2.57. This depression was independent of serum albumin level and body weight. Cell-mediated immunity was further depressed following radiotherapy and did not improve following enteral alimentation for 3 weeks. In untreated patients, there was a significant rise in levels of IgA (298 +/- 184 mg/100 ml) as compared to normal (154 +/- 54 mg/100 ml). Levels of IgA did show a downward trend following enteral hyperalimentation. Circulating immune complexes and serum CEA level were elevated in almost 50% of patients. These data confirm the influence of tumor-related impairment of cell-mediated immunity while nutrition appears to affect IgA levels.

Two studies were conducted to measure the metabolic influence of tumor growth in rats. Parameters for the metabolic state were wound-healing qualities of colon and skin. Both early and later stages of tumor growth lowered wound healing qualities to a statistically significant degree. No anorexia or weight loss was found in this rat-tumor model during the study period. Intravenous hyperalimentation (IVH; with proteins and carbohydrates) of tumor-bearing rats stimulates tumor growth but at the same time restores wound-healing qualities to control levels, both during early and later stages of tumor growth. It is suggested that tumor growth leads to an as yet not measurable disturbance of the metabolic equilibrium but that IVH can replenish the tumor-bearing host and restore the metabolic equilibrium.

Twenty-one consecutive patients with pancreatic abscess were managed by an open packing technique. Despite an anticipated mortality of less than 65 per cent predicted by Ranson's prognostic signs, the mortality in this group of patients was only 14 per cent. The marked improvement in results was attributed to several factors: earlier diagnosis and surgical intervention based upon serial abdominal tomography; prevention of persistent or recurrent sepsis by frequent scheduled dressing changes, and prevention of frequently related complications. Seven patients were found to have significant anaerobic involvement. All wounds were permitted to heal by secondary intention, and each patient received intravenous hyperalimentation. The average duration of hospitalization was 76 days, a period not differing significantly from that required by conventional closed methods of drainage. Open packing of pancreatic abscesses appears to represent a significant advance in the management of these difficult patients.

The coexistence of malignancy and dysphagia makes nutritional deprivation especially serious in patients with carcinoma of the esophagus. Intravenous hyperalimentation (IVH) is often given and should be of particular value in these patients. Sixty-four patients with carcinoma of the esophagus seen between January, 1975, and February, 1982, were studied retrospectively during their first hospitalization for the disease. Thirty-seven patients received IVH, and 27 did not. There were no significant differences at the time of admission to the hospital between the two groups with respect to age, sex, pathological status, and location of the carcinoma. Also, there was no difference in the incidence of hypoalbuminemia (less than 3 gm/dl) or lymphocytopenia (less than 1,500/mm3). More patients in the IVH group underwent surgical resection of the esophagus. Surgical intervention did not significantly influence hospital mortality. The IVH therapy reduced weight loss (p less than 0.05), but was associated with an increased incidence of pulmonary sepsis (p less than 0.05) and longer hospital stay. The incidence of hypoalbuminemia and lymphocytopenia increased between admission and the end of hospitalization, but it did not significantly differ between the groups. Thus, one cannot assume the effectiveness of IVH in this clinical setting, as its value was not demonstrated in this retrospective series. A prospective randomized study is warranted in view of the high cost and the doubtful clinical impact of an IVH regimen in patients with carcinoma of the esophagus.

Intravenous hyperalimentation with dextrose can be associated with adverse respiratory and hepatic effects. The purpose of this study was to determine the respiratory and metabolic consequences of fat calories in excess of resting energy expenditure provided both continuously and discontinuously. No significant changes in respiratory mechanics, oxygen consumption, carbon dioxide production, resting energy expenditure, serum substrates, liver function, or nitrogen balance were noted by the addition of 500 kcal of lipid emulsion to dextrose calories sufficient to meet energy requirements. The respiratory quotient declined significantly with the 12- and 24-hour lipid infusions, but persisted for the entire 24 hours only in the latter instance. The sustained and increased (46% v 36%) oxidation of lipid with a 24-hour infusion suggests that a continuous infusion of lipid is preferable to a discontinuous infusion.

During a 9-year period, 204 infants younger than 12 months of age had 294 Broviac central venous hyperalimentation catheters inserted. Fifty-nine adult-size and 235 infant-size Broviac catheters were used. Catheter insertion was via the saphenous vein (267), external jugular (7), internal jugular (16), cephalic (2), and transthoracic right atrial veins (2). General anesthesia was used for all internal jugular, but for only 11 saphenous catheters. Catheter function ranged from 6 to 925 days (mean, 112 days). Forty-four infants had malabsorption syndromes, 36 had short bowel syndrome, 38 had intractable diarrhea, and 86 required nutritional support for a variety of other conditions. Fifteen of the 204 infants developed inferior (10) or superior vena caval thrombosis (2), or both (3). Thrombosis occurred in 13 of the 267 infants with saphenous catheters (4.9%), and five of the 25 with jugular or cephalic venous catheters (20.0%). Obstruction to normal catheter infusion was the first sign of caval occlusion. Transient mild leg edema (4) and prominent venous pattern over the legs (3) were present with inferior vena caval (IVC) occlusion, but no patient had renal vein obstruction or died as a direct result of this condition. Each of the two patients with superior vena caval (SVC) occlusion experienced mild to moderate edema and venous suffusion of the head and upper extremities, and one developed a pleural effusion. Each of the three infants with combined superior and inferior vena caval thrombosis died from pulmonary insufficiency within six months after SVC occlusion.(ABSTRACT TRUNCATED AT 250 WORDS)
