Two college students developed symptoms of poisoning following ingestion of a salt solution during a college physiology laboratory exercise. Symptoms included nausea, vomiting, diarrhea, and altered consciousness. The ingested solution was identified as isotonic buffered saline containing sodium azide in a concentration of 1.0 g/L. The solution was commercially prepared for instrumentation use only and was used inadvertently for the exercise instead of freshly preparing sodium chloride in water. One student drank three sips of the solution and survived. The other student drank 700 to 800 mL and over several days became progressively ill, suffering myocardial damage and cardiac dysrhythmias, and, finally, died. Toxicologic studies confirmed the presence of azide in an antemortem urine sample from the deceased. Sodium azide is an uncommon but potent poison which can cause serious illness and death.

Hypernatremia is a potentially life-threatening electrolyte abnormality. This problem develops most often because of loss of water from the animal, but in rare cases hypernatremia results from gain of sodium chloride. Important conditions predisposing to hypernatremia include diarrhea, vomiting, heat stroke, fever, limited access to water, excessive diuretic use, renal diseases, and pituitary diabetes insipidus. This condition rarely develops if animals have adequate access to water. Clinical signs relate to central nervous system derangements and can progress to seizures and coma. Diagnosis is based on the serum sodium concentration; treatment should be instituted if it is greater than 170 mEq per L. Treatment is based on knowledge of the volume status of the patient and the probable cause for the hypernatremia. In general, 5 per cent dextrose in water or other hypotonic fluids are given slowly intravenously. The rate of administration should be adjusted so the water deficit is replaced over 48 to 72 h. Too rapid correction of hypernatremia can lead to cerebral edema and worsening of the animal. In cases of salt intoxication, diuretics must be given in addition to slow water replacement to avoid the development of pulmonary edema.

Three male infants with vomiting, dehydration, hyponatremia, hyperkalemia and metabolic acidosis were found to have vesicoureteral reflux (VUR) and urinary tract infection. Two were initially thought to have the salt-losing form of congenital adrenal hyperplasia. Although prompt diagnosis of this potentially fatal condition is critical, its mimicry by urosepsis in infants with VUR is actually more common. Infection probably causes unresponsiveness of the distal renal tubules to aldosterone.

Potassium is one of the most abundant ions in the human body and yet it is difficult to assess potassium balance. Potassium chloride is extensively used as a potassium supplement, both by physicians as a therapeutic modality and by the general public, mostly in the form of salt substitute. Therapeutically, both the oral and intravenous forms of potassium are utilised. Overdose of potassium is not as frequently encountered in clinical practice as hyperkalaemia (excess potassium in the body) due to acute or chronic renal disease. Potassium homeostasis is maintained very delicately and is governed by the daily consumption of potassium and the renal excretion mechanisms. Any change in these or related factors can present as hyperkalaemia. However, potassium overdoses leading to serious consequences do occur. Orally, the dose of potassium has to be large enough so that the normal excretory mechanisms for potassium are overcome and clinical toxicity occurs. It takes a much bigger dose of ingested potassium to produce toxicity in a person with normal renal function than in patients with compromised renal function. Potassium toxicity manifests in significant, characteristic, acute cardiovascular changes with ECG abnormalities. Besides cardiovascular effects, neuromuscular manifestations in the form of general muscular weakness and ascending paralysis occur. Gastrointestinal symptoms manifest as nausea, vomiting, paralytic ileus, and local mucosal necrosis which may lead to perforation. It is imperative when treating hyperkalaemia that the whole clinical picture is taken into account rather than the numerical potassium values. Only the extracellular potassium can be measured in the laboratory, yet 98% of the body potassium is intracellular and cannot be measured. In acute overdose situations due to ingestion of potassium salt, the general principles of treatment for overdoses should be followed. Calcium chloride infusion, dextrose and insulin in water, and correction of acidosis with sodium bicarbonate are helpful in controlling the acute, life-threatening cardiac arrhythmias. These modalities do not remove the excess potassium from the body. That is achieved either by utilising ion-exchange resins or by mechanically removing potassium via haemodialysis. To curtail inadvertent or accidental potassium overdoses, physicians should prescribe any potassium supplements very carefully to their patients and monitor the plasma potassium periodically.

Two male infants with hyperpigmentation, vomiting, lethargy and weight loss were reported. Hypoglycemia, hyponatremia, hypochloremia, hyperkalemia and metabolic acidosis were suggestive diagnosis of salt losing adrenocortical insufficiency. The absence of ambiguous genitalia, low 24 hour urinary 17 KS and pregnanetriol excretion precluded congenital adrenal hyperplasia. Low basal levels of plasma aldosterone and cortisol and low 24 hour urinary 17 OHCS excretion with disability to increase their corticosteroid secretions after ACTH stimulation as well as furosemide and theophylline infusions were supportive for the diagnosis of congenital adrenal hypoplasia. The definitive diagnosis was confirmed by ultrasonogram and computerized tomography. Family histories suggested X-linked recessive inheritance in these reported cases. Evidence of progressive postnatal adrenocortical degeneration was documented by progressive deterioration of adrenocortical functions beginning from mineralocorticoid to total corticosteroid deficiencies. The increased brain serotonin synthesis as the associated pathology of X-linked congenital adrenal hypoplasia was proposed on the basis of elevated basal plasma GH and PRL levels in the reported cases, taken together with an incidence of congenital LH deficiency and persistent ACTH hypersecretion in corticosteroid treated patients reported elsewhere.

Twenty patients receiving a variety of emetogenic cytotoxics (including cisplatin in 5) were given a single i.v. infusion of 40 micrograms kg-1 of BRL43694 (as the hydrochloride salt) in successive groups of 3-4 patients between 0-6 hours after chemotherapy. Eleven patients were completely protected from vomiting; 9 had mild to moderate nausea and vomiting, but none severe enough to require alternative anti-emetic 'rescue'. In 4 of the patients in whom BRL43694 was delayed until 4-6 h after chemotherapy, vomiting had already begun; in each case immediate termination of vomiting occurred when BRL43694 was infused. No adverse effects attributable to the anti-emetic were observed. Mean pharmacokinetic parameters in 14 patients in whom plasma assay data are available were: Maximum observed concentration = 30.7 ng ml-1; terminal phase half-life = 8.96 h; total body clearance = 0.376 (1 h-1) kg-1; apparent volume of distribution = 2.85 l kg-1. This study shows BRL43694 to be an effective and well tolerated anti-emetic. Further studies aimed at defining an optimal dose and schedule for use against the most emetogenic cytotoxics are in progress.

Six cases of acute renal failure associated with mefenamic acid therapy are described. Five patients were non-oliguric and five patients had clinical features of salt and water depletion. In these patients the presenting symptoms were abdominal pain, diarrhoea and vomiting. Renal biopsy in five patients showed interstitial nephritis and mesangial proliferation. All patients recovered without specific therapy after withdrawal of the drug, but in four patients mild renal impairment persisted. These findings indicate that both interstitial and mesangial changes are common features of acute renal failure due to mefenamic acid therapy.

Experimental and clinical experience with compounds containing antimony have shown that the trivalent compounds are generally more toxic than the pentavalent ones. APT can cause severe pain and tissue necrosis and is therefore not given by intramuscular or subcutaneous injection. APT has the actions and uses of AST, but it is less soluble and more irritating than the sodium salt which is therefore more suitable for intravenous use. Trivalent antimony compounds are toxic when used topically. Adverse effects are similar for all trivalent compounds, and include nausea, vomiting, weakness and myalgia, abdominal colic, diarrhoea, and skin rashes, including pustular eruptions. Hypersensitivity reactions also occur. Respiratory symptoms include cough, dyspnoea, and chronic lung changes. Cardiotoxicity is the most important and may produce arrhythmias, myocardial depression and damage, Stokes-Adams attacks, heart failure, and cardiac arrest. Hepatic damage and necrosis, as well as blood dyscrasias, may occur. Toxic effects on the kidney may follow chronic use. Continuous treatment with small doses of antimony may give rise to symptoms of subacute poisoning, similar to those of chronic arsenic poisoning, due to accumulation of antimony in the body, especially if trivalent compounds are used, because of their long biological half-lives. Reproductive disorders and chromosome damage have been reported; antimony compounds are, therefore, potentially toxic to reproduction and have mutagenic, and oncogenic potential. Antimony compounds should, therefore, not be used during pregnancy or in the presence of hepatic, renal, or heart disease. Pentavalent antimony preparations especially the organic compounds, together with non-metallic synthetic preparations, such as the diamidines, have now replaced APT for use in leishmaniasis. Because of the toxicity of antimony compounds, investigations have been undertaken to reduce their adverse effects by combining them with chelating agents. These preparations appear to have reduced the toxic effects of antimony without affecting the efficacy of the preparations. Liposome-encapsulated antimony products have, more recently, been shown to be much less toxic because of the reduced dose of the antimony compound required for effective therapy. The historical uses of antimony were based on the belief that the topical and systemic adverse effects, for example, skin eruptions and diarrhoea and vomiting, were signs that the condition being treated was responding by being brought to the surface to relieve congestion at the diseased area. There is no evidence in topical use, but there is evidence that such use can cause severe reactions.(ABSTRACT TRUNCATED AT 400 WORDS)

We have examined whether the addition of powdered rice and pulses (Dal moong) to oral rehydration solution will decrease the purging rate and thereby increase the efficacy of the oral rehydration therapy. The study was carried out on 60 male infants, with acute watery diarrhoea, moderate dehydration but without fever, vomiting, or other conditions like septicaemia and meningitis. The infants were treated with either the standard WHO oral rehydration salt solution (ORS) or with a modified solution where glucose was removed and powdered rice and Dal moong were added. We found that the infants receiving ORS with powdered rice and Dal moong had significantly lower fluid losses in the stools, a significant and more rapid weight gain, and needed significantly less fluid than the infants receiving ORS only.

Continuous infusion of metoclopramide was compared with bolus dosing in a randomized, double-blind study in 27 patients receiving cisplatin therapy. Hospitalized patients receiving their first course of cisplatin (120 mg/sq m administered i.v. over four hours) were randomized to receive either bolus doses or a continuous infusion of metoclopramide. In the infusion group (14 patients), a loading dose of metoclopramide 3 mg/kg (total body weight) as the hydrochloride salt was infused over one hour immediately before the administration of cisplatin, followed by a continuous infusion of metoclopramide 0.5 mg/kg/hr (as the hydrochloride salt) for 12 hours. Each patient received a total metoclopramide dose of 9 mg/kg over 13 hours. These patients also received five bolus doses of 5% dextrose injection (as placebo) over 15 minutes, with the first dose given one hour before the cisplatin and four more doses at two-hour intervals. In the bolus-dose group (13 patients), metoclopramide 2 mg/kg as the hydrochloride salt was added to each of the bolus doses, while the continuous infusion was a placebo of 5% dextrose injection. All patients also received dexamethasone 10 mg i.v. and diphenhydramine hydrochloride 50 mg i.v. Patients were monitored for 24 hours after initiation of metoclopramide administration for number of emesis episodes and for adverse effects. In the infusion group, 11 of 14 (79%) patients had two or fewer episodes of emesis. In the bolus group, 10 of 13 (77%) had two or fewer vomiting episodes. Mild sedation occurred in both the infusion (79%) and bolus-dose (77%) groups. Despite the use of diphenhydramine, extrapyramidal reactions were seen in one bolus-dose patient and two infusion patients.(ABSTRACT TRUNCATED AT 250 WORDS)
