Despite the widespread use of non-steroidal anti-inflammatory drugs (NSAIDs), the current number of reported cases of poisoning is small. However, with the introduction of 'over-the-counter' preparations of NSAIDs in some countries (e.g. ibuprofen in the UK and USA) an increased incidence of acute poisoning from this group of drugs can be expected. Conventionally, NSAIDs are divided into the following groups based on their chemical structure: arylpropionic acids, indole and indene acetic acids, heteroarylacetic acids, fenamates, phenylacetic acids, pyrazolones and oxicams. Unless NSAIDs are ingested in substantial overdose, acute poisoning with these agents does not usually result in significant morbidity or mortality. In most cases the clinical features are mild and confined to the gastrointestinal and central nervous systems, though acute renal failure, hepatic dysfunction, respiratory depression, coma, convulsions, cardiovascular collapse and cardiac arrest may complicate severe poisoning. Arylpropionic acid derivatives were thought initially to have a low order of toxicity in overdose but, in addition to anticipated gastrointestinal symptoms, headache, tinnitus, hyperventilation, sinus tachycardia, hypoprothrombinaemia, haematuria, proteinuria and acute renal failure have been described. In addition, drowsiness, coma, nystagmus, diplopia, hypothermia, hypotension, respiratory depression and cardiac arrest have been reported in severe cases of poisoning. Oxyphenbutazone and phenylbutazone are considerably more toxic in overdose. Complications of severe poisoning include coma, convulsions, hepatic dysfunction, acute renal failure, sodium and water retention, haematuria, cardiovascular collapse, respiratory alkalosis, metabolic acidosis, hypoprothrombinaemia and thrombocytopenia. In contrast, indomethacin appears to be much less toxic. In addition to gastrointestinal symptoms, indomethacin taken in overdose induces headache, tinnitus, dizziness, lethargy, drowsiness, confusion, disorientation and restlessness. Only 1 case of acute sulindac poisoning has been reported in the literature. A 16-year-old boy was admitted with hypokalaemia (2.2 mmol/L), transient granulocytosis and 'scanty' haematemesis after ingesting 12 g sulindac. No case of acute tolmetin poisoning have been reported. The fenamates (flufenamic acid, meclofenamic acid, mefenamic acid, tolfenamic acid) are, with the exception of mefenamic acid, not as widely prescribed as other groups of NSAIDs. In overdose, mefenamic acid may result in nausea, vomiting, diarrhoea, muscle twitching, convulsions and coma.(ABSTRACT TRUNCATED AT 400 WORDS)

An oral liquid form of ivermectin was administered to 14 purebred Collies (12 rough coated, 2 smooth coated). All Collies were given ivermectin at dosages of 100 and then 200 micrograms/kg of body weight. Three of the dogs developed mild clinical signs of toxicosis (salivation, vomiting, confusion, ataxia, and tremors) with the 100 micrograms/kg dosage. After the 200 micrograms/kg dosage, 7 dogs (including 1 smooth-coated Collie) developed severe toxicosis (seizure-like activity, recumbency, nonresponsiveness, and coma). Because dogs that developed severe toxicosis were not retreated, only the 7 remaining dogs were given ivermectin at 600 micrograms/kg. Severe toxic signs were not observed in the dogs given the 600 micrograms/kg dosage, and only 1 of these 7 dogs developed severe toxicosis when given ivermectin at 2,500 micrograms/kg. Dogs that developed severe toxicosis were given supportive care while in the comatose state. All dogs recovered completely. The results indicated that Collies (including the smooth-coated Collies) have a wide range of sensitivity to ivermectin-induced toxicosis.

The authors present a case with a ruptured saccular aneurysm of the left fronto-orbital artery and the coexisting anastomosis with the left anterior ethmoidal artery, accompanied by subarachnoid hemorrhage and intracerebral hematoma in the left frontal lobe. A 44-year-old male, whose past history had been uneventful, was admitted complaining severe headache and vomiting, followed by confusion. CT examinations revealed subarachnoid hemorrhage and intracerebral hematoma in the left frontal lobe. Left carotid angiograms disclosed a saccular aneurysm described above. Emergency operation in a state of grade 3 according to Hunt and Kosnik revealed a saccular aneurysm and its parent artery which was thought to be proximally a left fronto-orbital artery and distally a left anterior ethmoidal artery, which was seen to penetrate the anterior cranial fossa at the lamina cribrosa. Then the aneurysm was excised following clipping of the neck. Thereafter, the patient showed favorable recovery. The histological examination revealed absence of the media and the internal elastic lamina in the wall of the aneurysm with slight infiltration of round cells. Generally speaking, distal anterior cerebral artery aneurysms, which arise on branches beyond the anterior communicating artery, occupy 2-5% of all cerebral aneurysms, and most of them are found at the branching site of the pericallosal artery. As far as the authors know, there was few or no report referring to the aneurysm arising on the fronto-orbital artery, as shown in this case. Also, as for the aneurysm arising on the anterior ethmoidal artery, there are a few reports.(ABSTRACT TRUNCATED AT 250 WORDS)

The pharmacokinetics and acute toxicity of carmustine (BCNU) have been studied in ten patients receiving high-dose combination chemotherapy with cyclophosphamide, cisplatin, and BCNU as treatment for advanced neoplasms. Patients received from 300 to 750 BCNU mg/m2 of body surface area as a 2-hour infusion. The immediate effects of this schedule of BCNU included tachycardia, hypotension, flushing, confusion, nausea, and vomiting. Hypotension was a prominent feature of high-dose BCNU administration. The pharmacokinetics of high-dose BCNU were studied via serial blood samples obtained during and following BCNU infusion. Concentrations of BCNU in total plasma and ultrafiltrable (bioavailable) plasma were determined by high-pressure liquid chromatography with UV detection. Average pharmacokinetic parameters for bioavailable plasma BCNU, calculated on the basis of a one-compartment model, include an elimination constant of 0.031 min-1 and a volume of distribution of 5.1 L/kg. Average clearance of total plasma BCNU is 77.6 ml/kg/min. When corrected to a constant dose of 1 g/m2, the average peak concentration at the end of the infusion was 7.8 microM and the area under the curve was 538 microM X min. Plasma BCNU was largely (77%) protein bound. The distribution, clearance, and protein binding of high-dose BCNU were similar to those reported for standard-dose BCNU.

Seventy nine cases of sporadic, community acquired legionnaires' disease have been reviewed. Annual and seasonal variation in incidence was noted. The mean age of the patients was 53 years and 50 (63%) were male. Pre-existing chronic diseases were present in only 23 (29%), including two patients receiving immunosuppressive treatment. Common symptoms included unproductive cough, dyspnoea, chest pain, headache, confusion, nausea, vomiting, and diarrhoea. Respiratory symptoms were absent, however, in 17 (22%). Localising chest signs were present in 74 (95%) cases. Frequent laboratory findings included lymphopenia, high erythrocyte sedimentation rate, hyponatraemia, raised urea and creatinine concentrations, abnormal liver function, hypophosphataemia, hypoalbuminaemia, proteinuria, and haematuria. Thirteen patients died (16%), including nine of 20 who received assisted ventilation. The mortality rate in patients treated with erythromycin (11%) was lower than in those who received other antibiotics (23%), but this difference was not statistically significant. Of the features noted on admission, only a high plasma urea concentration was significantly associated with death. Sporadic community acquired legionnaires' disease is a not uncommon disorder, which with appropriate treatment has a prognosis similar to that of other forms of community acquired pneumonia.

This study reviews liver disease in toxemia of pregnancy based on 102 cases submitted to the Armed Forces Institute of Pathology. The common clinical features were right upper quadrant and epigastric pain, nausea, vomiting, and elevation of the serum transaminases. Jaundice occasionally developed. These occurred in severe preeclampsia or eclampsia and their cause was usually recognized. However, hepatic symptoms and signs did result in inappropriate diagnoses and misdirected therapy. Such confusion occurred when these were the initial problems confronting the clinician in women presenting with advanced toxemia due to poor prenatal care. They were also likely to be misleading when other more classic parameters, such as blood pressure and proteinuria, were only midly abnormal. Central nervous system complications were the common cause of death but liver disease could be partially or wholly responsible. Extensive periportal lesions, hepatic hematomas, spontaneous rupture, and infarction all contributed to hepatic injury and to morbidity. Fibrin deposition, hemorrhage, or both in the periportal areas was characteristic of the histopathology. Scanning electron microscopy validated this spectrum of change. A toxemic vasculopathy related to severe vasospasm in the hepatic arterial circulation may be responsible.

We questioned whether there was any way to predict which patients with high serum theophylline levels would develop life-threatening toxicity and thereby determine which patients might benefit from prophylactic therapeutic measures, such as hemoperfusion or hemodialysis. We reviewed the records of 54 consecutive patients seen over a five-year period in whom the serum theophylline level was 39 micrograms/ml or higher (range 39-78 micrograms/ml, mean theophylline level 49.5 +/- 9.6 micrograms/ml). Toxicity sought included cardiovascular--major arrhythmias (asystole, ventricular tachycardia, ventricular fibrillation) and minor arrhythmias, (central nervous system--major [seizures], minor [confusion, agitation]); and gastrointestinal (nausea, vomiting and diarrhea). In our sample of patients with extremely high theophylline levels, the incidence of life-threatening complications was low, and the subgroup of patients with high serum theophylline levels who developed life-threatening toxicity could not be easily identified. We conclude that major interventional procedures such as hemoperfusion or hemodialysis should not be used prophylactically in this population of patients of middle age to elderly men with high theophylline levels. We recommend a more conservative approach of using oral activated charcoal therapy in all patients with high serum theophylline levels, and reserving hemoperfusion or hemodialysis for those patients who develop seizures or major arrhythmias.

Two cases of acute blindness due to quinine poisoning are presented. In both cases, the diagnosis was initially unsuspected. In addition, tinnitus, decreased hearing, vomiting, abdominal pain, and confusion were noted in one patient, and the other experienced decreased hearing, headache, confusion, tachycardia, later bradycardia, and first-degree atrioventricular block. The onset of blindness was delayed more than 12 hours after ingestion in both cases. Quinine levels of 13.6 micrograms/mL and 18.6 micrograms/mL were demonstrated (therapeutic = 1 to 3 micrograms/mL). One patient developed marked constriction of visual fields and some residual decreased acuity, while the other regained normal visual acuity.

From April 1982 through February 1984, 29 patients with pancreatic cancer were treated with ifosfamide (1.25-1.5 g/m2 on days 1-5) + N-acetylcysteine (NAC) 2 g p.o. every 6 h on days 1-7 every 3 weeks. In responding patients without serious toxicity, subsequent courses of ifosfamide were escalated every 3 weeks by 0.25 g/m2 per day to a maximum of 2 g/m2 per day, with escalation of NAC to 12 g/day. Patients with KPS less than 50, serum creatinine or bilirubin greater than 2 mg/d 1, or obstructive uropathy were ineligible. The median age was 54 (range 36-78), median KPS 70, and median pretreatment weight loss 9 kg. Toxicity included nausea, vomiting, moderate myelosuppression, and occasional mental confusion. Hematuria (greater than 11 RBC/HPF) developed in only 1/29 courses (17 patients) of ifosfamide at greater than or equal to 1.75 g/m2 per day, and in 7/52 courses (27 patients) overall (13%). Of 27 evaluable patients 6 responded (22%), including 1 with complete response. The median survival was 6 months. Based upon these results, we are currently evaluating ifosfamide + 5-fluorouracil in pancreatic cancer.

Evidence for cow's milk allergy was looked for prospectively in 15 children with recurrent vomiting. Whereas radiological examination showed gastro-oesophageal reflux to be present in all patients, 3 out of 15 children presented an enteropathy associated with an increased number of IgE plasmocytes in small intestinal biopsy tissue. These three patients did not improve with conventional medical therapy but a striking improvement occurred within 24 h on a cow's milk-free diet. We conclude that diagnostic confusion between gastro-oesophageal reflux and cow's milk allergy can occur and that the presence of IgE plasmocytes in small intestinal biopsy tissue indicates IgE-mediated cow's milk protein allergy. All cases of "intractable" gastro-oesophageal reflux should be suspected of cow's milk allergy and investigated accordingly.
