Psychomotor status--a female case in the 34th week of pregnancy.

A case report is presented here. A 33-year-old female who had been medicated with Chinese medicine showed a typical psychomotor status which conformed to all items of Heintel's and Treiman and Delgado-Escueta's diagnostic criteria of psychomotor status. When she was 33 years old in the 34th week of pregnancy on April 11, 1981, she was found to be in an epileptic twilight state during which a delirious state and some automatisms were observed. As the incidence of automatisms gradually increased, she was finally seized with a typical psychomotor status in which automatisms were quite periodically and frequently repeated without complete recovery of consciousness between seizures. This status still continued despite an intravenous injection of diazepam and phenytoin and barely ceased with the medication of clonazepam and carbamazepine four days after the beginning of the status.

A multicentre double-blind comparative trial of zimeldine and imipramine in primary major depressive disorders.

Zimeldine, a new antidepressant with a selective inhibition of 5-HT reuptake, was compared with imipramine in a double-blind comparative study. The trial was conducted on 95 patients with primary major depressive disorder, of endogenous character. During the 4-week study period clinical efficacy was evaluated by using the Hamilton Depression (HAM-D) scale, Beck's Inventory and global ratings. Zimeldine (100 mg b.d.) was shown to have as good an antidepressive effect as imipramine (50 mg t.d.s.) when evaluated on the HAM-D scale. Assessment of the symptom improvement on this rating scale suggested that zimeldine was more effective in improving the patient's insight of the disease. There was no significant difference between zimeldine and imipramine as assessed by a final global improvement rating scale as well as by the patient's own impression. Exploratory data analysis revealed that zimeldine was significantly more effective than imipramine in the following groups; patients over 40 years of age; patients whose initial onset of illness occurred at over 40 years; patients with a history of at least three episodes of depressive illness; patients with mild to moderate depression; and patients who had previously failed to show an appreciable response to other antidepressant treatment. Analysis of global safety ratings revealed that zimeldine is significantly safer than imipramine, with a lower incidence of adverse symptoms involving the autonomic nervous system, especially anticholinergic reactions. No significant difference was observed between the two groups with respect to abnormal laboratory reports. One zimeldine patient developed symptoms suggesting a hypersensitivity reaction (fever, skin eruption and elevation of plasma levels of transaminases), which led to the patient's withdrawal from drug treatment.

A comparison of the clinical effects of timiperone, a new butyrophenone derivative, and haloperidol on schizophrenia using a double-blind technique.

The efficacy and safety of timiperone, a new butyrophenone derivative, in schizophrenia as compared with haloperidol were assessed in a multi-clinic double-blind controlled study in a total of 206 patients. The patients were given timiperone (1.0 mg/tablet) or haloperidol (1.5 mg/tablet) in a daily dose of 1--3 tablets for the first day, then up to a maximum of 12 tablets depending on symptoms for 12 weeks. Timiperone was found to be significantly superior to haloperidol in the final global improvement rating and in the general usefulness rating. In the over-all safety rating there were no statistically significant differences between the two drug treatments. With regard to analysis by stratification timiperone was superior to haloperidol in improving abnormal experiences such as hallucination and delusion as well as deficiency of initiative and blunted affect. From these results it is considered that timiperone could be superior to haloperidol in the treatment of schizophrenia.

Psychomotor status induced by temporal lobe encephalitis.

A case report of psychomotor status was presented. A 51-year-old male caught a cold and had a high fever at the end of September, 1979. On October 7th, he had a visual hallucination followed by a generalized seizure. After hospitalization he went through several fits of automatism. On October 15th, he was seized with automatism status in which the seizures were repeated every 25 minutes and there was no recovery of consciousness between the seizures. Although an intravenous injection of diazepam interrupted this status, on October 17th he showed subclinical seizure status on the EEG during which automatism traces were rarely found. By the medication of carbamazepine and clonazepam, he improved gradually. CT-scan revealed the disappearance of the right sylvian fissure and CSF showed findings of viral encephalitis. Consequently, he was considered to have been suffering from temporal lobe encephalitis and shown an episode of psychomotor status with automatisms and automatism traces during which typical automatism status was observed as well.

Psychomotor status: case reports and proposal for classification.

Two cases with psychomotor status were reported. Case 1 is considered to have been seized with subjective seizure status which lasted 10 hours. Case 2 most likely suffered the typical psychomotor status which satisfies all of Heintel's criteria. The relationship between ictal patterns and EEG recordings was discussed and the classification proposed.

Comparison of efficacy of amoxapine and imipramine in a multi-clinic double-blind study using the WHO schedule for a standard assessment of patients with depressive disorders.

A multi-clinic double-blind controlled study on amoxapine in comparison with imipramine, using the WHO Schedule for a Standard Assessment of Patients with Depressive Disorders, was performed and the data were analyzed with 111 patients. The assessment of severity of illness and overall improvement indicated clearly the superiority of the antidepressive effect of amoxapine to that of imipramine. The onset of antidepressive effect of amoxapine was clearly more rapid than that of imipramine, and in more than half of the patients in the amoxapine group the improvement was seen within four days following the drug administration. Amoxapine was superior to imipramine in terms of safety and usefulness. The side-effects due to amoxapine appeared less frequently and were less serious than with imipramine. The difference between amoxapine and imipramine was especially remarkable for hypotensive effect. The antidepressive effect of amoxaphine was superior to that of imipramine for almost all symptoms and signs. Amoxapine displayed an especially remarkable effect on psychomotor retardation, depressive feeling, anxiety and tension, somatic complaints and sleep disturbance.

Action of enpiprazole on emotional behavior induced by hypothalamic stimulation in rats and cats.

Action of enpiprazole on emotional behavior elicited by hypothalamic stimulation in rats and cats was investigated and comparisons were made with effects of diazepam. Two behavioral patterns were elicited by stimulation of the postero-medial part of the hypothalamus in rats: a food-carrying response beginning with exploratory movement and an analogue of fear. Enpiprazole frequently changed the food-carrying response into food-taking response and occasionally analogues of fear into food-carrying and /or food-taking responses. Thresholds for these behaviors were also elevated. Diazepam showed the same effects on the thresholds as enpiprazole, having but little effect on the behavioral patterns. In cats, enpiprazole evelvated the thresholds for affective-defensive responses induced by hypothalamic stimulation in 6 of 8 cases, but lowered them in 2 cases. This suggests that enpiprazple has a 'biphasic effect' in the central nervous system. By contrast,diazepam consistently elevated thresholds. Comparing the action of enpiprazole with that of diazepam it can be presumed that the former is a different type of anxiolytic drug than the latter.
