Accidental acute mercury vapor poisoning in three persons is reported. Three hours after exposure, symptomatology began by chills, vomiting, diarrhea and chest pain. Two patients, respectively 67 and 77 year old, presented severe pulmonary edema, then neurological symptoms with tremor and coma. This toxic pulmonary edema, which entailed artificial ventilation, was followed in both cases by an acute interstitial pulmonary fibrosis which led to death respectively after six and sixteen days. In the third case (a thirty eight year old patient) a skin rash, erythematous and pustuliform was observed. Analysis for total mercury by flameless atomic absorption showed very high mercury levels in blood and urine of the three patients. The effect of treatment by Dimercaptopropanol on renal excretion of mercury was studied. Optic and electron microscopy of the lung of the two patients who died showed the pulmonary changes of acute interstitial fibrosis.

95 506 patients who received general anesthesia during the period of 1964--1977 were studied. The account of all actual or possible life threatening complications during the anesthesia is given: oedema of the glottis, air embolism, accidental injection of the wrong drug, respiratory insufficiency, hypoxia, pulmonary oedema, airway occlusion by the cuff, vomiting and aspiration, anaphylactoid reaction, death within 24 hours, death on the table. Deaths not attributable to anaesthesia are listed separately. We have found that in one of every 139 anaesthetics given there was a life threatening complication to the patient. In every 197th anaesthetic there was a clear connection with the anaesthetic technique used. In contrast with the great number of near fatal complications the rate of irreversible damage or mortality connected with general anaesthesia was low.

Five patients who had injected intravenous (i.v.) phenmetrazine or methamphetamine developed marked prostration resembling septic shock, disseminated intravascular coagulation, rhabdomyolysis with myoglobinuria, and azotemia. Soon after injection, four noted chills, fever, sweats, nausea, and abdominal cramps. Within hours, they developed vomiting, myalgias, paresthesias, headache, and orthostasis. Cardiorespiratory arrest, accelerated bleeding, and noncardiac pulmonary edema were observed in one patient. From 4 to 11 litres of saline were required in the first 24 h to maintain blood pressure and urine output, suggesting that shock resulted from massive loss of intravascular volume into necrotic muscle. Recognition of this syndrome and treatment by aggressive volume replacement led to the recovery of all five patients.

The severity of acute mountain sickness (AMS) was investigated in healthy volunteers, airlifted to high altitude (5,360 m). Blood gases were measured at 2,990 m and 5,360 m. Symptoms of AMS were found in all subjects, but ranged from malaise to vomiting with intractable headache. The clinical severity of AMS was directly related to the arterial PCO2 and inversely to pH, but unrelated to the PO2 on arrival at high altitude. However, PO2 fell and was lowest 48 h after arrival at high altitude in those subjects with the most severe AMS. These were the only subjects to show an increase in the alveolar-arterial PO2 difference and in the venous admixture ratio during the first 48 h. These abnormalities in gas exchange, which developed in the subjects with the most marked cerebral symptoms, suggest that the manifestations of cerebral and pulmonary dysfunction at altitude develop simultaneously, a finding that suggests coexisting cerebral and pulmonary edema.

Eighty-two patients were hospitalized following an accidental exposure to chlorine. All patients presented with dyspnoea and cough. The other symptoms included irritation of throat (53.6%), irritation of eyes (42.3%), headache (29.2%), abdominal pain (26.8%), vomiting (24.3%) and giddiness (9.7%). All of them had bronchospasm and 5 (6%) had cyanosis at the onset. An x-ray of the chest revealed patchy infiltrates in 3 (3.85%) and hilar congestion in 2 (2.44%). Pulmonary function tests showed an obstructive pattern in 27.4%, restrictive in 3.25% and mixed in 53.2%. Pulmonary functions were normal in 16.1% of the patients. Bronchoscopy revealed tracheobronchial mucosal congestion in all cases, hemorrhagic spots in 35.7%, erosions and ulcers in 12.5%. All patients were treated with oxygen, aminophylline, hydrocortisone and antibiotics. Haematemesis (n = 1) and pulmonary oedema (n = 2) developed 12 hours after the admission. Two other patients developed pneumonia 48 hours later. All patients recovered satisfactorily. On follow-up 16 patients had no sequelae after one year. Pulmonary functions were normal in 5 patients after 3 years of follow-up.

Acetazolamide is a useful prophylactic for acute mountain sickness causing marked reduction in headache, nausea, vomiting, weakness, etc. Improvements correlate with increased arterial oxygen concentrations, reduction in proteinuria and peripheral oedema and other objective measures of acute mountain sickness. Evidence that Acetazolamide is beneficial for pulmonary oedema or cerebral oedema is scanty because of the lower frequency of these severe forms of mountain sickness. Dexamethasone, used prophylactically, also reduces the symptoms of acute mountain sickness partly due to its euphoric effect. Use of Acetazolamide as a treatment for established acute mountain sickness has been investigated. Large doses of Acetazolamide increase arterial oxygen levels over a few hours and this leads to a reduction of symptoms but data is limited and faster acting carbonic anhydrides inhibitors such as Methazolamide may be preferable in an emergency situation. There is no comparison of the effectiveness of Acetazolamide with other drugs used for treating acute mountain sickness such as steroids and calcium channel blocking drugs. Also, there is no data on drug combinations which could have additive effects and thereby be more beneficial than individual drugs.

All children admitted to Madina Maternity and Children's Hospital, Saudi Arabia, in 1989 because of scorpion stings (primarily Leiurus quinquestriatus) were studied. Of 96 children studied, 20 suffered either shock, pulmonary oedema or both. These 20 shared characteristic clinical features such as vomiting, priapism and failure to maintain normal temperature and/or blood pressure. The management protocol emphasized fluid restriction and the i.v. administration of venom antitoxin. Doubling the recommended dose did not improve the outcome. Two children died and the rest recovered.

Poisoning is a significant problem in the elderly. The majority of poisonings in older people are unintentional and may result from dementia and confusion, improper use of the product, improper storage or mistaken identities. Depression is also common in the elderly and suicide attempts are more likely to be successful in this age group. The elderly patient's recuperative abilities may be inadequate as a result of numerous factors including impaired hepatic or renal function as well as chronic disease processes. General management of poisoning in the elderly parallels management of younger adults, but it is especially important to ascertain underlying medical conditions and concurrent medications. In most poisonings, activated charcoal and cathartic are sufficient. Haemodialysis or haemoperfusion may be required at lower plasma drug concentrations in elderly patients. While the specific indications for antidotes are the same for all age groups, dosage alterations and precautions may need to be considered in the elderly. Drugs most often implicated in poisonings in the elderly include psychotherapeutic drugs, cardiovascular drugs, analgesics and anti-inflammatory drugs, oral hypoglycaemics and theophylline. Cardiovascular and neurological toxicities occur with overdoses of neuroleptic drugs and, more frequently and severely, with cyclic antidepressants. Patients with pre-existing cardiovascular disease are at particular risk of worsening ischaemic heart disease and congestive heart failure. Benzodiazepines only appear to produce significant toxicity during long term administration or in combination with other CNS depressants. Digoxin can cause both chronic and acute intoxication, most seriously cardiac toxicity including severe ventricular arrhythmias, second or third degree heart block or severe refractory hyperkalaemia. Immune Fab antibody is indicated for the management of digoxin toxicity, although patients dependent on the inotropic effect of digoxin may develop heart failure after digoxin Fab antibody administration. Nitrates can cause toxicity including headache, vomiting, hypotension and tachycardia from excessive sublingual, transdermal or intravenous doses. Conduction disturbances and hypotension occur with overdoses of antihypertensive drugs; these effects are mild with angiotensin converting enzyme (ACE) inhibitors, occasionally severe with beta-blockers and of significant concern with calcium channel antagonists. The elderly commonly use aspirin and other salicylates, are more likely to develop chronic intoxications to these agents, and are more susceptible to severe complications such as pulmonary oedema. Salicylate poisoning, recognition of which is often delayed, should be considered in elderly patients with neurological abnormalities or breathing difficulties, especially in the setting of acid-base abnormalities. The clinical effects of NSAID overdose are mild and usually involve the central nervous system and gastrointestinal tract.(ABSTRACT TRUNCATED AT 400 WORDS)

This is a case report of immediate acute pulmonary edema following the intravenous administration of Stronger Neo-Minophagen C (glycyrrhizin) and Chlor-Trimeton (chlorpheniramine maleate). The patient was a 15-year-old Japanese boy who had a previous history of surgery for right testicular tumor and adverse reactions to contrast media. The patient complained of severe headache, nausea, and vomiting just before the end of intravenous administration of these drugs, which were being given to prevent an adverse reaction to contrast enhanced CT. The symptoms disappeared within a few minutes, but chest CT examination performed immediately after the onset of the adverse reaction showed ill-defined consolidations with air bronchogram, especially in the anterior portion of both lungs. One day later, the abnormalities coalesced and poorly marginated patchy opacities developed. A week later, the abnormal densities disappeared. CT findings suggested acute pulmonary edema, especially in the anterior portion of both lungs. Thus CT examination was useful to detect focal pulmonary edema even in a patient with no particular respiratory symptom.

Intravenous fluorescein angiography is a commonly performed and extraordinarily valuable diagnostic procedure. The frequency of adverse reactions after angiography has varied considerably in previous reports. In a prospective study of 2789 angiographic procedures in 2025 patients, the authors found that the percentage of adverse reactions depended strongly on the patient's angiographic history. Overall, adverse reactions followed 4.8% of the angiographic procedures. These reactions included nausea (2.9%), vomiting (1.2%), flushing/itching/hives (0.5%), and other reactions (dyspnea, syncope, excessive sneezing) (0.2%). No cases of anaphylaxis, myocardial infarction, pulmonary edema, or seizures occurred. The percentage of reactions was 1.8% for patients who had had previous angiography without ever having had an adverse reaction. In contrast, the percentage of reactions was 48.6% for patients who had had an adverse reaction to angiography previously.
