Three cases of diencephalic syndrome, associated with brain tumors, are reported in this paper. Case 1. A 2-2/12-year old boy was initially admitted to our hospital because of failure to thrive which began at the age of three months. Physical examination revealed emaciation (weight, 7.8 kg), irritability and pallor without anemia. Horizontal nystagmus was seen. Laboratory studies were normal except for abnormally high plasma growth hormone (p-GH) which was incompletely suppressed by hyperglycemia (induced by glucose) and was not elevated by hypoglycemia (induced by insulin). A low grade astrocytoma of the optic nerve compression the hypothalamus was partially removed. After the operation followed by irradiation, p-GH returned to normal both in its basal level and in its reaction to insulin loading, then his gain of weight was accelerated. He was readmitted, however, at the age of 6 8/12 years with headache and vomiting. Since subtotal removal of the recurrent tumor and irradiation, preoperative symptoms have disappeared up to the present (7 9/12 years old). Case 2. A 3-9/12-year old girl was initially admitted because of failure to thrive since the age of 2 years. Examination on admission revealed emaciation (10.5 kg), irritability and right hemiparesis. Laboratory studies were normal except for high serum cholesterol (290 mg/dl). (p-HG was not measured) The patient had been well after the subtotal removal of the hypothalamic astrocytoma except occasional headache until the age of 6 years. She was readmitted at the age of 9 years with progressive emaciation.(ABSTRACT TRUNCATED AT 250 WORDS)

Lethargy, anorexia and vomiting suggest azotemia in cats with FUS. Clinicopathologic findings may include azotemia, hyperphosphatemia, hyperglycemia, hyperkalemia, and signs of urinary tract inflammation on urinalysis. Treatment of FUS depends on the degree of illness but generally includes removal of the urethral obstruction, bladder lavage, fluid and antibiotic therapy, and subsequent feeding of a canned, low-Mg diet with added table salt.

Thirty-seven cases of canine hypoadrenocorticism were compared with 39 previously reported cases. The 2 series were compared because it was believed that a study of 37 consecutive cases diagnosed at 1 institution (Michigan State University) and compiled by 1 group of veterinarians would yield data that were more representative of the disease than multiple cases from various institutions. Age, sex, and breed data were similar in both series. The frequency of anorexia, vomiting, depression, and the mean values for the clinicopathologic data were similar for both series except for blood glucose concentration (P less than 0.025). The Michigan State University series was different in that it had a lower frequency of eunatremia, increased plasma total solids, and hypoglycemia but a higher frequency of lymphocytosis, lymphopenia, hyponatremia, hyperglycemia, and hypercalcemia. Further, 3 dogs in the Michigan State University series had azotemia plus near isosthenuric urine, suggesting renal disease, but they seemingly responded to therapy for hypoadrenocorticism. Only 1 such case was identified in the literature. Finally, we detected fewer instances of P waves not being evident in lead II of an electrocardiogram.

Succinylated Acinetobacter glutaminase-asparaginase (SAGA) has broader antitumor activity than Escherichia coli L-asparaginase in experimental systems; moreover, drug resistance does not develop in tumor cell lines initially sensitive to this enzyme. We have investigated the pharmacology and toxicology of SAGA after both single-dose and serial daily dose injections in 20 adult patients. Glutaminase activity in plasma after i.v. injection of single doses did not follow simple first-order kinetics (half-life during the initial 24 hr was 21 +/- 9 hr. A linear relation was observed between increasing doses of SAGA and resultant levels of plasma enzyme activity and blood glutamate. Assay of whole blood which had been deproteinized immediately following phlebotomy showed that single doses of SAGA lowered glutamine only transiently to nondetectable levels; serial daily doses were required to achieve and maintain continuous glutamine depletion. Reversible depression of the central nervous system, ranging from encephalopathy to coma, occurred in a dose-related manner and was dose limiting. Other prominent reactions included respiratory alkalosis, hyperglycemia, nausea, and vomiting. Transient antitumor effects were noted in two patients with solid tumors and in two patients with leukemia. SAGA causes considerable neurotoxicity in adults which requires close patient monitoring. Phase II studies in leukemic patients are in progress.

The authors report 9 cases of acute non traumatic pancreatitis in children. The most common symptom in their patients is atypical abdominal pain often associated with vomiting (5 cases) and shock (4 cases). Among laboratory investigations: --High serum amylase level (average: 1 045 UI/l) is constant, associated with hypocalcemia and hyperglycemia in 3 patients. --Radiographic findings on plain film of the abdomen are diagnostic in 4 cases. --Abdominal ultrasound is the most reliable test and positive in the only patient on which performed. Among etiologies, drug induced pancreatitis is the most common (5 cases) due to combined Prednisone-L-Asparaginase (4 patients): --A duodenal ulcer and a case of choletithiasis are reported. --In 2 patients no determinant factors are found. A good response to parenteral nutrition, gastric suction and antisecretory agents is observed in 7 cases. 2 leukemic patients died shortly after the acute episode.

Salicylate poisoning remains a major clinical hazard, usually resulting from accidental ingestions in preschool children, suicidal overdoses in adults and teenagers, and therapeutically acquired intoxication in all ages. Alkalemia or acidemia, alkaluria or aciduria, hypoglycemia or hyperglycemia, and water and electrolyte imbalances may occur; nausea, vomiting, tinnitus, hyperpnea, hyperpyrexia, disorientation, coma, and/or convulsions are common. With chronic, therapeutically induced salicylism, these symptoms may be mistaken for symptoms resulting from the illness for which the salicylates were administered. For acute ingestions, the magnitude of the poisoning is clearly dose related. Blood level determinations are good prognostic indicators for acute ingestions but are of limited value in chronic, therapeutically induced salicylism. Fluid and electrolyte management is the mainstay of therapy. Diuresis, hemodialysis, and hemoperfusion are effective, but the latter two rarely are necessary.

Enzyme-linked immunosorbent assays for detection of Tityus serrulatus venom antigen and of horse anti-T. serrulatus venom antibodies were carried out before antivenom treatment and at 1, 6, 12, and 24 hr after antivenom therapy in 18 patients with systemic manifestations following T. serrulatus scorpion sting. Increased levels of circulating venom antigens were detected in the patients before antivenom treatment, but were no longer detected 1 hr after specific antivenom therapy. High titers of antivenom persisted for at least 24 hr after treatment with antivenom. The evolution of clinical and laboratory manifestations of envenoming showed that vomiting and local pain decreased within 1 hr and hyperglycemia was no longer detected 12 hr after antivenom therapy. The cardiorespiratory manifestations disappeared 6-24 hr after the administration of antivenom and all patients recovered completely. This study demonstrates the efficacy of antivenom therapy in neutralizing circulating venom antigens and supports the prompt administration of a potent antivenom to patients with systemic manifestations of envenoming.

The Southwest Oncology Group (SWOG) studied the response rate and toxicity of merbarone (1,000 mg/m2 IV continuous infusion days 1-5, q 21 days) in patients with advanced metastatic renal cell carcinoma. Among 36 eligible patients, there was one partial response for a response rate of 3% (95% C.I. 0.1-15%). There were no mixed responses. There were no treatment related deaths or adverse drug reactions. Significant anemia, diarrhea, and hypercalcemia were observed. Mild to moderate degrees of malaise/fatigue/lethargy, dizziness/vertigo, hyperglycemia, creatinine increase, nausea, vomiting, weight loss, pedal edema, dyspnea, and granulocytopenia were noted. Merbarone does not have significant activity as a single agent in advanced renal cell carcinoma.

This study was designed to determine the threshold dose for toxicity, the potential for serious medical complications, and the medical care required after unintentional albuterol ingestion in children. This study was prospective and descriptive. Data were obtained on pediatric albuterol ingestions evaluated emergently as reported to three regional poison control centers. Data elements included dose ingested, physical findings, medical treatment, and outcome. During 18 months, 78 patients who ingested albuterol and who received urgent medical evaluation were identified. Mean age was 2.8 years. The amount ingested ranged from 0.2 to 8.8 mg/kg. The most commonly reported signs of toxicity were tachycardia (57%, 44/78), widened pulse pressure (50%, 27/54), hyperglycemia (50%, 12/24), agitation (45%, 35/78), low serum carbon dioxide (42%, 10/24), vomiting (26%, 20/78), and hypokalemia (26%, 9/35). We found a threshold dose o 1 mg/kg for three or more signs of toxicity (P < 0.01). No patient required any specific treatment for toxicity. Seventy-two percent of patients were discharged from medical care within six hours of ingestion. Albuterol overdose in children causes a variety of cardiovascular, neuromuscular, and metabolic effects that are usually benign. The threshold dose for the development of three or more signs of toxicity is 1 mg/kg or three to 10 times the recommended daily dose. Toxicity is short-lived and does not require specific therapy or hospital admission in most cases.

When glucose utilisation is impaired due to decreased insulin effect, ketones are produced by the liver from free fatty acids to supply an alternate source of energy. This adaptation may be associated with severe metabolic acidosis and tends to occur in patients with type I (insulin-dependent) diabetes mellitus. In addition, hypovolemia is an almost invariable finding with marked hypoglycemia and is primarily induced by the associated glucosuria. Ketoacidosis stimulates both the central and peripheral chemoreceptors controlling respiration, resulting in alveolar hyperventilation (Kussmaul's respiration). With the ensuing fall in pCO2 the patient tries to raise the extracellular pH. A fruity odor of acetone on the patient's breath sometimes suggests that ketoacidosis is present. The classical triad of symptoms associated with hyperglycemia are polyuria, polydipsia, and weight loss. Circulatory insufficiency with hypotension is not uncommon due to the marked fluid loss and acidemia. In more severely affected patients, neurologic abnormalities may be seen, including lethargy, seizures or coma. Some patients also have marked vomiting and abdominal pain. The history and physical examination may provide important clues to the presence of uncontrolled diabetes mellitus. Once suspected, the diagnosis can be easily confirmed by measuring the plasma glucose concentration. Glucosuria and ketonuria can be semiquantitatively detected with reagent sticks. Blood gas analysis and anion gap give objective information as to the severity of the metabolic acidosis. Therapy must be directed toward each of the metabolic disturbances: hyperosmolality, ketoacidosis, hypovolemia and potassium, and phosphate depletion. The mainstays of therapy are the administration of low-dose insulin and volume repletion.(ABSTRACT TRUNCATED AT 250 WORDS)
