Patients with anorexia nervosa frequently demonstrate dehydration, electrolyte imbalance and low blood pressure that are secondary to starvation. Hyperactivity of the Renin-Aldosterone system and insensitivity to the pressor effects of exogenous angiotensin II are observed in Pseudo-Bartter syndrome caused by the abuse of diuretics or laxatives and self-induced vomiting, however, little information about the Renin-Aldosterone system has been reported in patients with anorexia nervosa. This study was designed to investigate the secretory function of the Renin-Aldosterone system in anorexia nervosa. The subjects were 13 patients with anorexia nervosa and 6 normal controls. Experiment 1: Angiotensin II infusion test was performed. Blood pressure was measured every 5 minutes, and the samples for plasma renin and serum aldosterone analysis were taken every 15 minutes during infusion test. Experiment 2: Plasma renin activity and serum aldosterone concentration were measured before and after one-hour walking. The results were as follows; (1) Basal plasma renin activity and serum aldosterone concentration in patients were not significantly higher than those in normal subjects. (2) Hypertensive response with elevation of the diastolic pressure during angiotensin II infusion in patients similar to that of normal subjects was observed. (3) Responses of plasma renin activity and serum aldosterone concentration after one-hour walking were significantly greater in patients than in normal subjects.(ABSTRACT TRUNCATED AT 250 WORDS)

During a 2-year period from January 1988 to December 1989, 125 patients (68 boys, 57 girls), aged 30 days to 9 years, were diagnosed as rotavirus gastroenteritis at this hospital. Diagnosis was made by identification of the rotavirus antigen in stool samples by latex agglutination assay. Ninety-nine (79.2%) of them were under 2 years of age. The seasonal peak in incidence was from January to March. The most common clinical characteristics were watery diarrhea (100%), followed by vomiting (68.8%), fever (68.0%), cough (42.4%), rhinorrhea (17.6%), convulsions (6.4%) and moderate to severe dehydration (1.6%). Fecal occult blood was positive in 4 patients and fecal leukocytes were positive in one patient. Stool cultures revealed concomitant infections with enteropathogenic Escherichia coli in 4 patients. Of the 106 patients who underwent serum electrolyte examinations, serum sodium concentrations ranged from 135-145 meq/L in 81.9% (86/106) and serum potassium concentrations ranged from 3.5-5.0 meq/L in 86.8% (92/106). Leukocyte counts greater than 15,000/mm3 were found in 10.8% (13/120) of the patients. All 125 patients recovered from the diarrheal illness on follow-up. Our results showed a different seasonal distribution of this disease from that of a previous observation between 1983-1984 in Taipei City and provides original clinical information on rotavirus gastroenteritis in children living in an area of Taipei County. Using the simple and rapid latex agglutination assay, we can make early diagnosis of rotavirus gastroenteritis. Thus, early treatment and early isolation of patients to prevent nosocomial infection among hospitalized patients is possible.

Between August 24-October 20, 1985, an outbreak of acute diarrheal disease occurred among 1833 children in Imphal, Bishenpur, and Thoubal districts in Manipur State in India for an overall attach rate of 2/1000. 17 children died, a case fatality rate of 9/1000. Hospital and health center personnel treated 1711 cases with rehydration therapy (oral or intravenous fluids). Local, mainly unqualified, practitioners treated the remaining 122 cases with antidarrheal drugs. Children treated at home were more likely to die than those treated at health facilities (case fatality rates 0.6% vs. 4.9%; p.001). Nevertheless these case fatality rates were lower than those in a 1973-1974 outbreak of gastroenteritis in Manipur, perhaps because the health authority distributed oral rehydration solution packets during this 1985 epidemic. The leading symptoms were watery diarrhea (82.5%), vomiting (67.5%), and abdominal pain (37.5%). Children 5 years old tended to experience severe dehydration more so than younger children (31.3% vs. 12.5%). 58.8% of hospitalized cases were older children who suffered the highest death rate. (1.9%). Peak admissions occurred the last week of September ending on October 2. Yet during the decline phase, the admission rate of children 2 years old rose. 25.3% of cases sampled recovered V. cholerae with the highest isolation rate (30.8%) found in older children and adults. 50% of fecal samples of children 6-23 months old tested positive for rotavirus. The researchers did not find any obvious epidemiological link between the 3 areas. They concluded that the rotavirus epidemic which peaked the week after that of cholera represented the beginning of the usual rotavirus diarrhea season.

A case of isovaleric acidemia appearing as diabetic ketoacidosis with acute encephalopathy and pancytopenia was reported. A three-year-old male patient, with mild psychomotor retardation, had recurrent bouts of acute encephalopathy and pancytopenia after episodes of upper respiratory infection. At admission, he had vomiting associated with dehydration, acidosis, ketonuria, coma and a pungent, rather unpleasant odor. Laboratory features included hyperglycemia, hyperammonemia, hyperamylasemia, hypocalcemia, neutropenia, thrombocytopenia and subsequent anemia. Urine organic acid profiles showed profuse amount of 3-beta-hydroxyisovaleric acid (295 mg/ml) and isovalerylglycine (616 mg/ml) by gas chromatography-mass spectrometry. Levels of amino acids in the serum and urine were normal. The patient received treatment with rehydration and insulin, with rapid improvement. After the acute illness, blood glucose levels returned to normal. The patient was doing well on a low-protein diet in recent 3 months.

A case of a patient with organic hyperinsulinism complicated by the development of hyperosmolar state is described. The hyperosmolar state was induced by vomiting and dehydration during an acute urinary tract infection. Impairment of glucose metabolism was confirmed by the finding of reduced tissue sensitivity to insulin during a euglycaemic clamp.

An outbreak of acute gastroenteritis (AGE) occurred in a 201-bed geriatric convalescent facility in Los Angeles County during December 1988 through January 1989. The attack rate was 55% among residents and 25% among employees. Illnesses were characterized by vomiting and diarrhea to a lesser extent, and the absence of fever. Bacterial and parasitic tests in a sample of patients were negative. A 27 nm small round structured virus (SRSV) was identified in one of 30 stools studied by immune electron microscopy (IEM). While rotavirus and influenza A and B were found in three, one and three cases, respectively, no alternative etiologic agent could be demonstrated for most cases. The outbreak met Centers for Disease Control (CDC) clinical and epidemiologic criteria for Norwalk-like gastroenteritis. The death rate of residents was not elevated beyond baseline during the outbreak; however, one healthy employee had diarrhea and dehydration and died after developing an arrhythmia. An autopsy showed moderate, diffuse lymphocytic and neutrophilic myocarditis, and viral studies found influenza A in left ventricular tissue. Fourteen (25%) of 57 employee cases worked in occupations without routine stool or patient contact. At least nine of these employees lacked evidence of direct fecal contact, and transmission of infection in these cases may have been airborne.

Oral rehydration therapy (ORT) has been shown to be useful in decreasing mortality, reducing treatment costs and diminishing the frequency of complications in children under the age of five with acute diarrhea. The current concept of ORT includes not only the increase in the intake of fluids and the administering of oral solution in order to prevent or treat dehydration, but also the continuance of everyday feeding, the teaching of the child's mother to detect signs of dehydration and other alarming changes, as well as the non-administering of medication, especially those considered as anti-diarrheal or anti-vomiting, and limiting the use of antimicrobials, only to be used in special cases. The theoretical know-how of these concepts has been seen to be insufficient in order to increase the use of community-wide Oral Rehydration Therapy, being this the main purpose for the establishment of the Oral Rehydration Ward in teaching hospitals of second and third level, where the majority of its' personnel must come into contact with and share the responsibility of treating children with diarrhea. Within these wards students obtain information, ability and assurance in the effective actual management of children with diarrhea, including the correction of the state of dehydration through the administering of oral solutions. Another complementary benefit from the coming about of this ward is the decrease in the need to hospitalize the majority of the patient with diarrhea therefore reducing costs and any related complications. Oral rehydration therapy; diarrhea; dehydration; oral solutions.

Two enteric bacterial pathogens were concomitantly isolated from the feces of 18 infants less than 6 months of age admitted to the Assaf Harofeh Medical Center over a 7-year period. In all but two patients stool cultures grew enteropathogenic Escherichia coli, six of serogroup 0119. The other organisms cultured were Shigella, Salmonella, Campylobacter jejuni and Aeromonas hydrophila. The usual clinical presentation was diarrhea, dehydration and vomiting of acute onset, and low grade fever. Patients with gastroenteritis due to a single agent compared with multiple pathogens had a milder course of disease, a milder degree of dehydration and acidosis, a lesser need for i.v. fluid treatment and shorter hospitalization.

The authors report a case of jaundice occurring secondary to severe vomiting in pregnancy in the first trimester. This is a rare clinical entity (occurring in 0.2-3 cases per thousand) although some people say it does not exist. The physiopathology is still badly understood but it occurs most often between the fourth and eighth week of amenorrhoea. It is characterised by jaundice occurring secondarily to vomiting in the first trimester, with a rise in the bilirubin level in the blood and in the alkaline phosphatases. Sometimes there is a slight rise in the transaminases. The diagnosis can only be arrived at after having excluded all the other possible causes of jaundice which are mentioned in the text. Furthermore the way the condition progresses is an important argument for its aetiology because once vomiting ceases the jaundice goes. The treatment has to be symptomatic with correction of the dehydration.

Renal amyloidosis was diagnosed in 14 young Chinese Shar Pei dogs, all of which were related. Clinical signs were those of renal failure and included vomiting, anorexia, lethargy, polydipsia, polyuria, weight loss, and dehydration. Some dogs had a history of intermittent fever and joint swelling. Laboratory findings also were compatible with renal failure and included azotemia, hyperphosphatemia, low total CO2 content in serum, isosthenuria, proteinuria, and hypercholesterolemia. All dogs had medullary deposition of amyloid, and 9 of 14 (64%) had glomerular involvement. The remaining renal lesions were typical of end-stage renal disease. In some dogs, amyloid deposits were found in other tissues (eg, liver, spleen, stomach, small intestine, myocardium, lymph node, prostate gland, thyroid gland, and pancreas). Amyloid deposits were sensitive to potassium permanganate oxidation, suggesting the presence of amyloid protein AA.
