Thirthy-three alcoholics, aged between 31 and 82 years, were treated for 7 to 30 days with tiapride. The dosage was 600 mg/day (200 mg 3 times daily) by mouth or 100 to 800 mg/day I.M. Out of 27 cases of tremor treated, there were 25 favourable results, one average result and one nil result. Insomnia and character disorders, e.g. anguish, depression, nightmares, hallucinations, were improved during the first few days of treatment in 27 cases out of 30. Out of 12 cases of algo-paresthesia of the lower limb treated, the were 9 good or excellent results, 2 average results and 1 nil result. A favourable result was observed in 7 cases out of nine in vomiting, water brash (3 cases out of 4), and in 16 cases out of 20 in anorexia. No clinical or laboratory disturbance attributable to tiapride was noted in our patients whose general health was often very poor.

The effect of nalorphine on eliciting symptoms of either alcohol or narcotic withdrawal was studied. Five male alcoholics were challenged with nalorphine and saline, both while sober and during alcohol ingestion. After nalorphine, pulse rate decreased in patients when sober, but increased when they were ingesting alcohol. Nalorphine administration resulted, during alcohol ingestion, but not in the sober state, in lacrimation, a symptom of narcotic withdrawal, in one patient, and in the following symptoms of alcohol or narcotic withdrawal in one or more patients: weakness, anorexia, insomnia, disorientation, and tremor. These findings suggest that morphine-like alkaloids play a role in the mediation of alcohol withdrawal symptoms.

Twenty-two patients with Parkinsonism were treated with levoamphetamine and 12 of these with dextroamphetamine. Levoamphetamine resulted in a significant improvement in disability from Parkinsonism, although the reduction in total disability, tremor, akinesia, and rigidity scores was slight (ca 20 percent). Dextroamphetamine in lower dosage also reduced disability by some 17 percent. The most disabled patients, including those also on levodopa, showed the greatest response to amphetamines. Previously, amphetamines have been reported to be a selective treatment for the oculogyric crises of post-encephalitic Parkinsonism. Amphetamines are thought to cause the release of catecholamines from central neurones. Their action in Parkinson's disease may be limited because of pre-existing striatal dopamine deficiency. Side-effects of amphetamines, anorexia, and CNS stimulation are different from those caused by levodopa in patients with Parkinson's disease.

A double-blind study comparing the effects of carbidopa and levodopa combined in a single tablet with levodopa alone was undertaken in 50 patients with Parkinson's disease. After 6 months, there was a statistically significant improvement over baseline in total score, rigidity, and tremor only in the patients randomized to carbidopa/levodopa. In addition, 40 percent of the patients treated with carbidopa/levodopa showed obvious clinical improvement (a greater than 50 percent reduction in their total score) over treatment with levodopa alone. However, after 2 years, only 20 percent continued to show this improvement. Nausea, vomiting, and anorexia developed in 56 percent of patients on levodopa but in only 27 percent of patients on carbidopa/levodopa. However, abnormal involuntary movements, observed in 48 percent of patients on levodopa, were present in 77 percent of patients on carbidopa/levodopa. Despite the increase in abnormal involuntary movements, carbidopa/levodopa is more effective than levodopa.

A newly developed broad-spectrum fluoroquinolone, levofloxacin (LVFX, DR-3355), was evaluated in vitro and in vivo in comparison with ciprofloxacin (CPFX), ofloxacin (OFLX) and norfloxacin (NFLX). The results were as follows. 1. Antimicrobial activity Minimal inhibitory concentrations (MICs) against 480 clinical isolates including 16 different species were determined using the microbroth dilution method. LVFX showed excellent antimicrobial activities against Gram-positive and -negative bacteria. The MIC values of LVFX for Gram-positive bacteria were superior to those of the other quinolones tested. The MIC values of LVFX for Gram-negative bacteria were comparable to those of CPFX and superior to those of OFLX and NFLX. 2. LVFX concentrations in serum and sputum LVFX was orally administered in a single dose of 200 mg to 2 patients with chronic lower respiratory tract infections, and its concentrations in serum and sputum were measured at intervals using bioassay. The peak concentrations of LVFX in serum were 1.52 and 1.24 micrograms/ml, and 84-95% of serum level were detected in sputum. From these data, it appeared that LVFX penetrate well into the lung. 3. Clinical efficacy and adverse reactions Fifteen patients with respiratory tract infections were treated with LVFX, and the overall efficacy rate was 78.6% (excellent in 3 cases, good in 8, fair in 3, poor in 0). As adverse reactions, anorexia was observed in 2 cases, diarrhea in 1 case and tremor of finger in 1 case. Although an elevation of total bilirubin in serum was observed in a case as an abnormal laboratory finding, it was mild, transient and improved rapidly after the completion of LVFX treatment.

Fifty-eight patients undergoing restorative dental treatment at Guy's Hospital had been previously allocated on the basis of clinical assessment, including that of their dental anxiety, to treatment under local anaesthetic alone or in combination with i.v. midazolam or inhalation nitrous oxide. They were tested before and after dental treatment to determine their memory of dental procedures and changes in mood and bodily symptoms. The patients allocated to the midazolam treatment had significantly higher pre-treatment scores on the Bond & Lader mood factors of "anxiety" and "discontent". All the groups showed significant pre- to post-treatment reductions in sweating, palpitations, restlessness, dry mouth, muscular tension, nausea, loss of appetite and upset stomach and the extent of these reductions were not different for the different treatments. Midazolam treatment resulted in significantly greater reductions in self-ratings of bodily symptoms of anxiety, shaking and trembling compared with the control (local anaesthetic) group. Nitrous oxide resulted in a significant reduction in irritability, compared with controls. Both midazolam and nitrous oxide significantly reduced the patients' memory of the dental procedures and the impairments in memory were independent of any changes in anxiety or sedation. Of the items remembered there were no differences between the groups in their ratings of how well explained, how pleasant or unpleasant, or how painful the procedures were.

We treated 28 patients (16 women and 12 men) who had essential tremor with methazolamide. Their median age was 69 years (range, 34 to 89 years), and the median duration of tremor was 16 years (range, less than 1 to 69 years). Fifteen cases were familial and 13 were sporadic. Improvement in 10 patients who continued taking the drug ranged from moderate to complete relief. In addition, four patients had marked improvement and two had moderate improvement but discontinued use of the drug because of side effects. Five patients with a mild response and seven with no response also discontinued methazolamide therapy. The maximal mean daily dose was 203 mg for all patients and 129 mg (maintenance dose) for the patients who continued taking the drug. Side effects consisted primarily of somnolence, nausea, epigastric discomfort, anorexia, paresthesias, and numbness. No aplastic anemia was noted in any of the patients. The median duration of follow-up was 6 months (range, 10 weeks to 29 months). The therapeutic effect seemed unrelated to a family history of tremor, the effect of alcohol, or the responsiveness to propranolol or primidone. Methazolamide may be an effective drug in the treatment of some patients with essential tremor, particularly those with head and voice tremor.

According to the hypothesis that the development of physical dependence on and tolerance to opiates depends on the inhibition by opiates of L-asparaginase and L-glutaminase activities in the brain, and the blockade by opiates of the aspartatergic/glutamatergic receptors especially NMDA, four female and fourty-four male heroin addicts were included in a double-blind clinical trial. Four mg chlorpromazine (CPZ) was administered every hour and 10 mg diazepam (DIA) every 6 hours to a group consisting of two female and nineteen male inpatients. The remaining subjects received 15 mg non-opioid antitussive dextromethorphan (DM) instead of CPZ. The withdrawn addicts were controlled twice a day and yawning, lacrimation, rhinorrhoea, perspiration, goose flesh, muscle tremor, dilated pupils, anorexia, joint and muscle aches, restlessness, insomnia, emesis, diarrhea, craving and rejection of smoking as abstinence syndrome signs were observed and rated on a scale of 1, 2 and 3 points according to their intensity. All signs, except perspiration and emesis, were significantly less intense in the group given DM + DIA than CPZ + DIA. The other plus points included the immediate stop of craving and the early onset of smoking in DM + DIA group. The results are considered to be supporting evidence for the hypothesis emphasizing the blockade of NMDA receptors by opiates in opiate addiction. Furthermore, the decrease caused by non-opioid NMDA antagonists in the responsiveness of NMDA receptors appears very promising for the treatment of opiate addicts.

Mexiletine is a Class IB antiarrhythmic which has basic and clinical electrophysiologic properties similar to lidocaine. Like other Class I antiarrhythmic agents, mexiletine blocks the rapid inward sodium current responsible for phase 0 of the action potential. It has been noted in the clinical electrophysiology laboratory to have minimal effect on sinus node function and AV nodal and His-Purkinje system conduction. Pharmacokinetic studies have shown that oral absorption is rapid with bioavailability of 80-90%. Mexiletine is predominantly metabolized by the liver with elimination half-life of 9 to 12 hours. The antiarrhythmic effects of the primary drug's metabolites remain to be defined. Hemodynamic studies have shown mexiletine to have a lesser negative inotropic effect than procainamide or disopyramide. Although mexiletine as a single agent successfully suppresses 60 to 80% of spontaneous ventricular arrhythmias, it has lower efficacy in suppression of induced ventricular arrhythmias. Multiple studies have shown that as monotherapy mexiletine is effective in preventing the induction of ventricular tachycardia in approximately 20% of patients. When used in combination with a Class IA antiarrhythmic drug for suppression of induced ventricular arrhythmias, multiple investigators have reported greater efficacy. Neurological side effects (tremor, dizziness, memory loss) occur in approximately 10% of patients while gastrointestinal side effects (nausea, anorexia, gastric irritation) occur in up to 40% of patients. Proarrhythmia or other serious toxicity from the drug is uncommon.

The Isoparaffins covered in this manuscript are branched aliphatic hydrocarbons with a carbon skeleton length ranging from approximately C10 to C15. They are used in the manufacture of liquid imaging toners, paint formulations, charcoal lighter fluid, furniture polishes and floor clearners. Potential exposure exists in the petroleum, printing and paint industries. Isoparaffins have a very low order of acute toxicity, being practically non-toxic by oral, dermal and inhalation routes. However, aspiration of liquid isoparaffins into the lungs during oral ingestion could result in severe pulmonary injury. Dermally, isoparaffins have produced slight to moderate irritation in animals and humans under occluded patch conditions where evaporation cannot freely occur. However, they are not irritating in non-occluded tests, which are a more realistic simulation of human exposure. They have not been found to be sensitizers in guinea pig or human patch testing. However, occasional rare idiosyncratic sensitization reactions in humans have been reported. Instillation of isoparaffins into rabbit eyes produces only slight irritation. Several studies have evaluated sensory irritation in laboratory animals or odor or sensory response in humans. When evaluated by a standard procedure to assess upper airway irritation, isoparaffins did not produce sensory irritation in mice exposed to up to 400 ppm isoparaffin in air. Human volunteers were exposed for six hours to 100 ppm isoparaffin. The subjects were given a self-administered questionnaire to evaluate symptoms, which included dryness of the mucous membranes, loss of appetite, nausea, vomiting, diarrhea, fatigue, headache, dizziness, feeling of inebriation, visual disturbances, tremor, muscular weakness, impairment of coordination or paresthesia. No symptoms associated with solvent exposure were observed.(ABSTRACT TRUNCATED AT 250 WORDS)
