Potential abnormalities of taste were examined in bulimic subjects who purged by vomiting and in controls. When spatial testing of the tongue and palate was performed by direct local application of sweet, salty, sour, and bitter solutions, bulimics showed a selective spatial loss on the palate. The palate may be affected by purging because vomit is directed toward the roof of the mouth where the palate receptors are located. The data suggest that the acid in vomit damages these receptors. Bulimics and controls did not differ in their basal ratings of intensity or pleasantness of sweet, salty, sour, and bitter stimuli when these were sipped rather than directly applied to the tongue. However, after ingesting a glucose load, controls found sweet taste significantly less pleasant, whereas bulimics did not. The results suggest that bulimics may also have an abnormal experience of satiety.

A now 10 month old female infant suffered from persistent non ketotic neonatal hypoglycemia despite continuous intravenous application of glucose (greater than 10 mg/kg/min). There was only a transient response of blood glucose after intravenous administration of glucagon and prednisolon. Biochemical findings indicated hyperinsulinismus (insulin level of 26 mE/ml during hypoglycemia). Oral diazoxid treatment in high doses (22 mg/kg) stopped hypoglycemia episodes for several days but the newborn remained glucose infusion depended. Finally the treatment had to be interrupted because of vomiting. At the age of 4 1/2 weeks a subtotal pancreatectomy was performed. The histological examination of the pancreas confirmed the clinically suspected diagnosis of nesidioblastosis. After pancreatectomy the infant required insulin therapy. Since six months the girl is without insulin in a good condition. Despite periods of arrested head growth before pancreatectomy the psychomotoric development is normal.

A clinical trial was conducted to compare the safety and efficacy of a new oral rehydration solution (ORS) with that of the ORS recommended by the World Health Organization (WHO). One hundred thirty infants with dehydration due to acute diarrhea were randomized into two groups: 68 infants received the WHO ORS containing sodium and glucose in a concentration of 90 and 111 mmol/L, respectively, and an osmolality of 311 mosm/kg (ORS-90); 62 infants received an ORS containing sodium and glucose in a concentration of 60 and 90 mmol/L, respectively, with an osmolality of 240 mosm/kg (ORS-60). Treatment failure was noted in seven infants (10.3%) in the ORS-90 group; the causes of failure were high stool output (three cases), persistent vomiting (three cases), and ileus (one case). Only one patient in the ORS-60 group (1.6%) was considered a failure because of high stool output. No significant differences were noted in the serum sodium levels in either group of patients, both in relation to the natremia seen on admittance or that seen after rehydration. A trend was observed toward correction of hypernatremia or hyponatremia with both types of ORS. A similar situation was observed with respect to the variations seen in serum potassium levels. The results from this study suggest that there may be clinical advantages of using an ORS with concentrations of sodium and glucose and a total osmolality lower than that of ORS-90, because of the lower incidence of treatment failures.

Imipenem/cilastatin sodium (IPM/CS) was administered to 55 patients with respiratory tract infections (RTI). A clinical evaluation of IPM/CS was carried out in 51 patients, 28 with pneumonia, 4 with pulmonary abscess, 1 with pyothorax, 6 with bronchitis, 9 with bronchiectasis, 1 with diffuse panbronchiolitis and 2 with RTI with chronic obstructive pulmonary disease, and the clinical efficacy rate was 78.4%. Causative organisms were isolated in 23 strains out of 20 patients, such as Staphylococcus aureus 4 strains, Staphylococcus epidermidis 1 strain, Streptococcus pneumoniae 1 strain, Branhamella catarrhalis 1 strain, Haemophilus influenzae 2 strains, Klebsiella pneumoniae 4 strains, Pseudomonas aeruginosa 6 strains, Pseudomonas sp. 1 strain, Acinetobacter calcoaceticus 1 strain, Acinetobacter sp. 1 strain and glucose non-fermentative Gram-negative rod 1 strain. An eradication rate of 70.6% was obtained. An overall eradication rate of main causative organisms in RTI including S. aureus, S. pneumoniae, H. influenzae and K. pneumoniae was 75.0%. Clinical adverse effects were observed in 5 patients, and these were eruption in 2, itching in 1, vomiting in 1 and drug fever in 1. Abnormalities in laboratory test results were observed in 8 patients. These disappeared or returned to normal values after completion or discontinuation of IPM/CS administration. IPM/CS appears to be a useful antibiotic for the treatment of RTI, especially severe infections.

A 3 year old boy who had glutaric aciduria diagnosed at 22 months of age was admitted with a history of lethargy, vomiting, and fever. He had been receiving glucose polymers as part of his dietary management. He was severely hypernatraemic, but after resuscitation and rehydration made a good recovery. The possible aetiology of his hypernatraemia is discussed.

To determine if carbohydrates perfused into the ileum affect gastric emptying and circulating levels of gastrointestinal hormones, 18 healthy subjects were intubated with an oroileal tube. A 400-cal (60% carbohydrate, 20% protein, 20% fat) homogenized meal labeled with 111In-DTPA was then infused into the stomach over 10 min. Simultaneously, a test solution of normal saline (n = 6) or 12.5 (n = 4), 25 (n = 4), 50 (n = 2), or 100 (n = 2) mg/min of carbohydrates (75% rice starch, 25% glucose) containing a nonabsorbable marker, polyethylene glycol, was continuously perfused into the terminal ileum at 3 ml/min for 7 h. In one-half of the subjects the perfusate contained an amylase inhibitor (3.3 mg/ml) that reduced starch digestion and carbohydrate absorption. Gastric emptying was measured by a dual-headed gamma-camera. Plasma concentrations of hormones and the amount of carbohydrates passing the ileum were measured every 10 min. The amylase inhibitor significantly reduced the absorption of complex carbohydrates from the terminal ileum (p less than 0.05). Gastric emptying was significantly slowed by ileal perfusion of carbohydrates (p less than 0.01). This effect was enhanced by the amylase inhibitor (p = 0.06). Plasma concentrations of C-peptide, glucagon, motilin, gastrin, and human pancreatic polypeptide were not related to gastric emptying or ileal perfusates, but decreased concentrations of gastric inhibitory polypeptide and neurotensin and increased concentrations of peptide YY were significantly associated (p less than 0.05) with slowing of gastric emptying. Perfusing carbohydrates into the ileum was associated with nausea, abdominal pain, and vomiting, but we could detect no direct relationship between the onset of these symptoms and gastric emptying. Slowing of gastric emptying of a homogenized mixed meal by the entry of complex carbohydrates into the ileum may be partly mediated by peptide YY or nonvagally mediated neural mechanisms.

Patients with eating disorders often use diuretics to eliminate fluid to achieve lower body weight. Diuretic abuse can lead to severe hyponatremia. Central pontine myelinolysis, a disruption of the myelinated neurons of the pons, has been associated with rapid correction of severe hyponatremia. A case is presented of a 35-year-old woman who was brought to the emergency service by ambulance complaining of vomiting for 7 days and that she could not hear well because she was 'worn out'. Initial laboratory values included serum Na 91 mEq/l, K 1.6, Cl 46, bicarbonate 33, BUN 4 mg/dl, glucose 306 mg/dl. After 32 h of intravenous fluids, the serum Na was 126, K 4.0, Cl 89, bicarbonate 25, glucose 118 mg/dl. On the 3rd hospital day the serum Na was 139. On the 4th hospital day she was alert and appropriate. On the 5th hospital day, however, she was confabulating and chatty. The serum Na was 139. She progressed to develop a spastic quadriparesis, speech and swallowing difficulties. A magnetic resonance imaging scan showed central pontine myelinolysis. She acknowledged taking 400 mg daily of furosemide and drinking much water. She had a past history of anorexia nervosa. She had a residual weight phobia and strove to keep her weight below 106 lb. Her height was 5 feet, 6 inches. As illustrated by this case, diuretic abuse can cause severe hyponatremia and the subsequent risk of central pontine myelinolysis. In patients with severe chronic or subacute hyponatremia, a safe restoration rate for serum Na has been less than 0.55 mEq/l/h. Serum Na should be below 135 within the first 48 h and hypernatremia should be avoided.

Medium-chain acyl-CoA dehydrogenase deficiency is a recently described inborn error of metabolism characterized by episodes of coma and hypoketotic hypoglycaemia in response to prolonged fasting. Secondary carnitine deficiency has been documented in these patients as well as the excretion in the urine of medium-chain-length acyl carnitine esters, such as octanoylcarnitine. Based on the potential toxicity of medium-chain fatty acid metabolites and the beneficial responses of patients with other inborn errors of metabolism and secondary carnitine deficiency, oral carnitine has been proposed as treatment for children with medium-chain acyl-CoA dehydrogenase deficiency. We report the results of carefully monitored fasting challenges of an infant with this deficiency both before and after 3 months of oral carnitine therapy. Carnitine supplementation failed to prevent lethargy, vomiting, hypoglycaemia and accumulation of free fatty acids in response to fasting despite normalization of plasma carnitine levels and a marked increase in urinary excretion of acyl-carnitine esters. Potentially toxic medium-chain fatty acids accumulated in the plasma in spite of therapy. Based on this study of one patient, we stress that avoidance of fasting and prompt institution of glucose supplementation in situations when oral intake is interrupted remain the mainstays of therapy for medium-chain acyl-CoA dehydrogenase deficient patients.

A 57-year-old white man presenting frequent recurrent chest and precordial pain, heartburn (pyrosis) and post-prandial vomiting for the previous 33 years (one to two years after Bilroth II gastrectomy) was submitted to cardiovascular, endoscopic, radiologic and biochemical studies with negative results. Doctors recommended surgical operation because of an excessively long afferent loop, Several biologic markers were performed at our hospital (intestinal pharmacomanometry, i.m. clonidine test, plasma neurotransmitters plus hormones, oral glucose tolerance test, plasma insulin, etc.), revealing an autonomic nervous system (ANS) imbalance characterized by hyperactivity of the cholinergic plus hypoactivity of the noradrenergic central system. Psychiatric evaluation demonstrated Dysthymic Depression. Treatment with a small daily dose of amitriptyline (a drug which enhances central noradrenergic activity and exerts powerful anticholinergic effects) suppressed symptoms, normalized physiological plus hormonal plus neurochemical parameters and made depressive manifestations disappear. The results suggest that the ANS imbalance was related to depressive syndrome and potentiated by neurohumoral disorders depending on duodenal and jejunal exclusion, and on intestinal post-prandial hyper-osmolarity.

All cases of mumps meningoencephalitis diagnosed at our institution during the past 15 years were reviewed. There were 24 cases, 16 between 1973 and 1977, 3 between 1978 and 1985 and 5 in 1986 to 1988. Four of the recent cases occurred 19 to 26 days after receipt of a new mumps vaccine (Urabe Am 9 strain) released in Canada in 1986. The remaining 20 cases were clustered in winter and spring. The average age was 6.2 years and the ratio of males to females was 5:1. Clinical presentations were fever (90%), vomiting (90%), meningismus (70%), headache (65%), parotitis (50%) and seizures (30%). The mean cerebrospinal fluid white blood cell count was 513/mm3 (lymphocyte predominance); 55% of patients had a cerebrospinal fluid protein level of greater than 0.4 g/liter, and the cerebrospinal fluid:blood glucose ratio was greater than 0.4 in all. Two patients had adverse sequelae. The clinical and laboratory features of these cases were not significantly different from the vaccine-associated cases.
