Propofol or methohexitone was given to the same twenty patients on two separate occasions during total intravenous anaesthesia for microlaryngeal surgery. With propofol the quality of induction was superior. Fewer patients required supplementation. Heart rate and blood pressure were well controlled at levels of 110-120% baseline. There were fewer side-effects during maintenance and recovery. Patients were able to return home earlier. However, apnoea and pain on injection occurred frequently, the latter when injection was made into the dorsum of the hand. With methohexitone, apnoea, abnormal movement, nausea, vomiting, headache, restlessness and confusion were common. Cardiovascular variables were poorly maintained at levels of 170-180% baseline. The results suggest that propofol is suitable as the sole anaesthetic agent in patients undergoing microlaryngeal surgery.

The new fluorinated adenine analog, fludarabine, has been tested for efficacy in many tumor types over the past ten years. Two other similar nucleoside analogs are currently available for commercial use. Cytarabine is used principally as an antileukemic agent, and vidarabine as an antiviral. Unlike vidarabine, fludarabine is resistant to deactivation by adenosine deaminase. Data from Phase I and II trials suggest that fludarabine is potentially effective in a number of leukemias, including acute lymphocytic leukemia, acute nonlymphocytic leukemia, and chronic lymphocytic leukemia (CLL). Unfortunately, the doses required to achieve adequate response in the acute leukemias (greater than 75 mg/m2) were above the maximum tolerated dose, resulting in intolerable granulocytopenia, thrombocytopenia, and a life-threatening neurotoxic syndrome. In CLL: however, the dose required to achieve a satisfactory response is well within tolerated limits. Long-term survival statistics are not yet available, but historical perspective strongly correlates response to other agents with increased survival times. Toxicities seen at dose regimens of 15-40 mg/m2/d for five consecutive days include somnolence, metabolic acidosis, confusion, fatigue, nausea, vomiting, increase in serum creatinine and aminotransferase concentrations, and pulmonary and hepatic abnormalities. Mild to severe hematologic toxicity has been observed at all dose levels.

Diazepam (0.21 mg/kg; group 1) and midazolam (0.03 mg/kg; group 2) was applied for sedation in two groups of urological patients (n = 10 in each) requiring transurethral resection (urine bladder, prostata) using spinal or peridural anaesthesia. Before anaesthetic procedure, 500 ml hydroxyethyl starch were administered for precluding severe vascular depression. Patients receiving midazolam began to sleep within one minute. Heart rate dropped in both groups after injection of both benzodiazepines which was considered a physiological sleeping effect. No hypotensive reactions were registered. Using this therapy maximum PaO2 values of 14.9 kPa in group 1 (diazepam) were registered and of 14.0 kPa in group 2 (midazolam). During the operation all patients were arousable. Side-effects such as nausea, vomiting and confusion were not observed.

A 23 year old male developed abdominal pain, diarrhoea, and vomiting several hours after poisoning with acute triphenyltin intoxication in a suicide attempt. Severe ataxia, dysmetria, nystagmus, and blurring of vision soon supervened. Disturbance of consciousness and confusion developed 12 days later and lasted for two months. A delayed sensorimotor polyneuropathy was shown by electrophysiological studies to be due to axonal degeneration and demyelination. The neuropathy rapidly recovered after consciousness was regained.

Nineteen patients receiving cancer chemotherapy were randomized in a double-blind fashion to receive either (a) dronabinol, 10 mg plus placebo q.i.d.; (b) prochlorperazine, 10 mg plus placebo q.i.d.; or (c) dronabinol plus prochlorperazine, each 10 mg q.i.d. There were six evaluable patients in each of the two single-agent groups and five in the combination group. The median duration and severity per episode of nausea was significantly greater in the group receiving prochlorperazine alone versus the other two groups. The median duration per episode of vomiting was also significantly greater in the prochlorperazine group than in the other two groups. The proportion of patients vomiting was the same in all groups; however, only one patient in the combination group versus three each in the single-agent groups experienced nausea (p = NS). The majority of side effects were associated with the CNS, including somnolence, dizziness, and confusion. Side effects were somewhat more common in both groups receiving dronabinol, though they were not statistically different from the side effects in the group receiving prochlorperazine as a single agent. Efficacy, as measured by duration of nausea and vomiting and by severity of nausea, was significantly greater in both groups receiving dronabinol.

Thirty-seven patients with advanced incurable malignancies who were receiving their first course of cisplatin (greater than or equal to 90 mg/m2 bolus), alone or in combination with other antineoplastic agents, were entered in this randomized, double-blind study to determine the antiemetic efficacy of the addition of high-dose dexamethasone to lorazepam plus metoclopramide. All patients received lorazepam (1.5 mg/m2) and metoclopramide (2.0 mg/kg) intravenously (IV) 30 minutes before cisplatin, with the same dose of metoclopramide repeated 1.5, 3.5, 6.5, and 9.5 hours after the 30-minute cisplatin infusion. Patients were randomized to receive dexamethasone (0.5 mg/kg) or placebo by slow bolus injection 30 minutes before cisplatin. All patients were hospitalized for 24 hours and evaluated by observation after cisplatin and a patient questionnaire before discharge. Eighteen patients received metoclopramide and lorazepam without dexamethasone: six (33%) reported no vomiting and four (22%) reported no nausea or vomiting. Nineteen patients also received dexamethasone: 14 (74%) had no vomiting and 13 (68%) reported no nausea or vomiting. These differences were statistically significantly different (P = 0.013 and 0.005, respectively). The side effects attributable to the antiemetic regimen were somnolence (100%), confusion (8%), and diarrhea (46%), and were the same in both arms. Dexamethasone significantly improved the antiemetic efficacy of metoclopramide plus lorazepam without adding toxicity. This three-drug combination gave a high rate of control of acute emesis induced by high-dose cisplatin.

A five-year-old male was admitted to the hospital with generalized seizures. Enlarged lymph nodes raised the suspicion of cat-scratch disease. The diagnosis was confirmed by a positive history of a cat bite, typical histopathologic findings in the biopsy of the lymph nodes, and a positive skin test. Brain CT scan and LP were repeatedly normal. The clinical course was remarkable for recurrent episodes of status epilepticus refractory to usual anticonvulsant therapy and prolonged encephalopathy consisting of mental confusion, hemiparesis, tremor, chorea, and vomiting. All neurologic symptoms gradually resolved within nine months, without sequelae. Cat-scratch encephalopathy should be suspected in a child presenting with status epilepticus and enlarged lymph nodes. Aggressive and prolonged anticonvulsant therapy is strongly recommended.

A schizophrenic patient developed a characteristic clinical picture of neuroleptic malignant syndrome (NMS) while admitted to the hospital during an exacerbation of his psychiatric symptoms. Oral treatment of the NMS with bromocriptine (7.5 mg/day) or levodopa/carbidopa (125/12.5 mg) provoked intense vomiting in spite of domperidone (60 mg/day), which led to their discontinuation. In view of the deterioration of the symptoms, treatment was begun with lisuride (1-2 mg/24 h) subcutaneously. An obvious improvement was shown in 24 h, but levodopa/carbidopa (125/12.5 mg t.d.s. orally) had to be added later to achieve complete resolution of the NMS. During the recovery phase, while being treated with subcutaneous lisuride infusion and levodopa (p.o.), the patient presented with confusion, agitation, and hallucination. Lisuride infusion was stopped and levodopa was continued until complete resolution of the NMS. This case indicates that parenteral administration of lisuride or other dopamine agents such as levodopa (i.v.) or apomorphine (s.c.) may be considered an effective and practical way of treating NMS, particularly when the patient's condition makes it difficult or impossible to use other dopaminergic drugs by the oral route.

Ten urological patients with spinal anesthesia were sedated with midazolam 0.03 mg/kg i.v. A similar group (n = 10) was given placebo instead of midazolam (2 ml 0.9% NaCl). Patients who received midazolam slept lightly but were rousable. During the operation 2 l/min oxygen was administered via a nasal cannula; pO2 and pCO2 remained within normal limits throughout the procedure. No cardiovascular side effects such as hypotension or other reaction such as vomiting, nausea, or confusion were observed after midazolam. At the end of the operation all patients were fully awake and cooperative.

The occurrence of the munitions compound hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) in groundwater surrounding Army ammunition plants may result in contamination of local drinking water supplies. RDX exerts its primary toxic effect in humans on the central nervous system, but also involves gastrointestinal and renal effects. Symptomatic effects following acute exposure include hyperirritability, nausea, vomiting, generalized epileptiform seizures, and prolonged postictal confusion and amnesia. Health effects data were analyzed for RDX, and although no controlled human studies exist concerning the acute or chronic toxic effects of exposure to RDX, sufficient animal toxicity data are available to derive an ambient water quality criterion for the protection of human health. This paper summarizes the available literature on metabolism of RDX and human and animal toxicity. Based on noncarcinogenic mammalian toxicity data, and following the methodologies of the U.S. Environmental Protection Agency, an ambient water quality criterion for the protection of human health of 103 micrograms/liter is proposed for ingestion of drinking water and aquatic foodstuffs. A criterion of 105 micrograms/liter is proposed for ingestion of drinking water alone.
