The effect of guancydine (1-cyano-3-tert-amylguanidine) on systemic and renal hemodynamics was studied in nine patients with arterial hypertension. Antihypertensive drugs were withheld for 15 days before beginning the investigation. Average sodium intake was 105 meq/24 hours in some patients and 25 meq/24 hours in others. Patients received placebo during a control period that averaged 14 days. Guancydine was given for 7 to 18 days at an average dose of 21 mg/kg of body weight. Although mean arterial blood pressure decreased significantly in all patients, it reached normal levels in only two. There was no change in cardiac output. Glomerular filtration rate and renal plasma flow remained unchanged, whereas urinary sodium excretion diminished, suggesting an activation of the renin-angiotensin-aldosterone system. A substantial gain in body weight was noted. Nausea, vomiting, constipation, somnolence, restlessness, mental confusion, asthenia, and urine retention were observed. The anti-angiotensin effect of guancydine that has been described in animals was not observed.

Under the circumstances of limited health resources and immediate need for preventing the dehydration associated with diarrhea in infants, breastfeeding should be encouraged throughout the diarrheal episode. When this is not possible because of cessation or failure of lactation, an oral electrolyte solution should be administered. It should be sterile and provide a quantity of electrolytes not greatly in excess of 30 mEq/liter of sodium and potassium. There should be little possibility of an error in the dilution of the mixture if it is to be supplied in powdered form. Milk should be reintroduced after 24 hours and the electrolyte mix rapidly discontinued so as to minimize nutritional deficits. If no such electrolyte mixture is available, it is reasonable to alternate feedings of commercial soft drinks or bland teas with milk feedings. There should be specific instructions that the infant should be brought to the hydration center if more than 3 sequential feedings are lost by vomiting, if fever is present, or it the stools exceed the volume of 3 feedings. In general, dehydration of less than 5% of body weight can be managed by this program in the house, dehydration greater than 5% but less than 10% requires supervision by health authorities, and dehydration greater than 10% requires intravenous therapy in a hydration center. In those countries with cholera and during epidemics of shigellosis or enterotoxigenic Escherichia coli, solutions containing 90 mEq/liter of sodium should be given under ambulatory supervision. This solution should be discontinued when fecal losses moderate (less than 60 ml/kg/day) and the lower electrolyte solution (30 mEq/liter) substituted.

Acute digoxin poisoning, its recognition and management, are reviewed. The uses of syrup of ipecac, gastric lavage, activated charcoal, cholestyramine, colestipol, edetate sodium and cathartics as measures to terminate the drug exposure are discussed. Measures to hasten digoxin elimination, such as the use of furosemide, hemodialysis and digoxin-specific antibodies are reviewed. Supportive management may include treatment with atropine, phenytoin, lidocaine, propranolol, glucose, insulin and sodium polystyrene sulfonate. Proper management of digoxin poisoning involves the use of standard decontamination procedures (emesis or gastric lavage). Activated charcoal is strongly recommended, followed by rapidly acting cathartics. Antiarrhythmic therapy usually involves atropine sulfate and phenytoin sodium.

Eight patients with stones retained in the extrahepatic biliary tract underwent cholate sodium infusion for dissolution of the stones. In six patients, the stones disappeared. However, in two of the patients, the stones did not disappear, and they were removed with the ureteral basket. Infusion of cholate sodium was well tolerated by six patients, but was accompanied by nausea, vomiting, and abdominal pain in two patients. In one case, mucosal deformity of the common bile duct was noticed during the infusion, but it was not apparent on a subsequent cholangiogram. As a result of our experience, we conclude that cholate sodium infusion is a safe procedure for the attempted dissolution of retained common bile duct stones.

In a 10-day study, carbenicillin indanyl sodium cured urinary-tract infections in 22 of 30 patients (ages, 24-91). In 3 of the remaining patients the treatment was a failure; in 3 others the drug had to be discontinued because of diarrhea and vomiting; and in 2 instances it induced overgrowth of Candida albicans in the urine. Carbenicillin was lethal to Pseudomonas aeruginosa in all 9 cases, to Proteus mirabilis in all 6 cases, and to enterococcus in all 3 cases. A trimethoprim/sulfamethoxazole combination cured urinary-tract infections in 18 of 30 other patients (ages, 28-91), but failed in 3. In 3 patients it gave rise to a skin rash; in 2 to elevation of blood urea nitrogen and creatinine levels; in 1 to neutropenia; and in 1 to overgrowth of Candida albicans in the urine. Reinfection occurred in 2 patients. Carbenicillin indanyl sodium was more effective than the sulfonamide/trimethoprim combination.

Twenty-two patients with a complaint of sudden deafness were treated with one of the other of two radiopaque contrast media, 9 received daily doses of sodium iothalamate, and 13 were treated similarly with methylglucamine and sodium iodamide. Four of the first group and eight of the second demonstrated either an effective partial or a complete recovery of hearing function. Those failing to respond were generally classified completely deaf at admission and report nausea, vomiting, or vertigo at onset of sudden deafness. Treatment with sodium salts of triiodobenzoic acid derivatives, i.e., sodium iothalamate and methylglucamine and sodium iodamide, is judged to be effective in selected cases of sudden deafness.

A boy with pseudohypoaldosteronism was followed from birth to the age of 7 years. Failure to thrive, vomiting, dehydration, hyponatraemia and urinary sodium loss were prominent findings. Urinary excretion of corticosteroid metabolites was normal. Before treatment, excessively high plasma renin concentration was found, associated with a marked activation of aldosterone secretion. A renal biopsy showed pronounced hypertrophy of the juxtaglomerular apparatus. Persisting metabolic acidosis and an insufficient urinary acidifying capacity suggested the presence of distal renal tubular acidosis. Treatment with sodium bicarbonate and sodium chloride from 19 to 31 months of age resulted in normal growth and normal physical and mental development. The plasma electrolytes were normalized but a pronounced activation of the renin-aldosterone system persisted after therapy, and on sodium restriction this system responded with a considerable further activation.

Primary adrenocortical insufficiency is described in 3 dogs. Clinical signs included marked depression, vomiting, diarrhoea, weakness and bradycardia. Diagnosis was based on clinical signs and biochemical findings of hyperkalaemia, hyponatraemia and a lowered plasma Na+ : K+ ratio. Treatment during the acute illness consisted of intravenous fluids and hydrocortisone sodium succinate. Fludrocortisone acetate has maintained all dogs in good health. One dog was on treatment for 4 years.

Four patients having high-level quadriplegia developed elevated serum calcium concentrations (11 to 15.8 mg/100 ml) within three months of injury. All were young males (ages 15 to 19 years) and quadriplegic (C4-C7). Presenting symptoms were nausea, vomiting, polydipsia, polyuria and lethargy. In two patients severe muscle wasting and cachexia with clinical symptoms developed and persisted for several months. Laboratory studies in all patients showed negative calcium balance with hypercalciuria. Reduced renal function was seen in all patients but returned to normal with return of normal serum calcium. Alkaline phosphatase level was normal in three and elevated in one. Serum parathormone levels were normal. Roentgenograms revealed diffuse demineralization. Nephrocalcinosis and soft tissue calcifications developed in one patient. Primary treatment included reduced calcium intake, correction of dehydration, sodium infusion and remobilization. Corticosteroids, oral phosphates, furosemide and mithramycin were used with varying success to control prologned symptoms and severe hypercalcemia.

We studied 27 infants admitted to the hospital with acute diarrhea caused by human rotavirus (HRV) and obtained additional data on fecal excretion from ten outpatients with the same infection. The disease was characterized by watery diarrhea with fever and vomiting at the onset, isotonic dehydration, compensated metabolic acidosis, and increased concentrations of sodium and chloride but low concentrations of sugar in stools. Diarrhea usually ceased in three to four days when oral feedings were reduced or stopped but recurred mildly in four patients. Of 57 household contacts, 12 were symptomatic, 6 had HRV in their stools, and 19 had significantly increased serum HRV antibody titers. These features of the disease accord with available information on the pathogenesis of HRV infection. Knowledge of the clinical pattern of this newly diagnosable infection should help physicians to recognize and treat quickly this highly infectious, potentially dangerous illness.
