The clinical efficacy and safety of timiperone, a new butyrophenone derivative, on chronic schizophrenia was compared with clocapramine by the double-blind method using a total of eighty-eight patients, consisting of forty-four patients in each group. In the final global improvement rating, the global improvement rating in each week and the general usefulness rating, there were no statistically significant differences between the two groups. However, in the global improvement rating in each symptom, timiperone was significantly superior to clocapramine in delusion and showed a superior tendency to clocapramine in contact. Timiperone showed a higher improvement rate than clocapramine in hallucination and disturbance of self-consciousness. In the over-all safety rating, there were no significant differences between the two groups, but in accompanying symptoms and side-effects, timiperone showed significantly less tendency than clocapramine in dyskinesia, insomnia, constipation and nausea. From these results, including the analysis by stratification, it was considered that timiperone was a superior or equivalent neuroleptic in comparison with clocapramine against the negative symptoms as well as the positive ones of chronic schizophrenia, and was equally safe or safer than clocapramine.

Thirty-four patients were submitted to the conventional cervical myelography by administration of metrizamide (Amipaque) through three routes (lumbar 23, suboccipital 6, C1-C2 lateral 5). After the injection of metrizamide (4-11 ml, 170-250 mgI/ml), all procedures of the cervical myelography were done as soon as possible within 9 minutes. The adverse reactions of Amipaque were observed in 29 cases (85%) out of 34 cases initially 1 hour after cervical myelography and disappeared completely in an average of 16 hours. The total number of the side effects was 140 incidences such as meningeal irritation (headache 18, nausea 17, vomiting 17), cerebellar signs (dizziness 11, dysarthria 8, tremor 5, bradylalia 2, dysmetria 2, tipsy feeling 2, dysdiadochokinesis 1), autonomic signs (flushing 7, pale face 4, fever 4, sweating 2, hiccup 2, fatigability 2, micturition disturbance 1), sensory signs (exacerbation of numbness 6, perioral numbness 3, back pain 1, chest pain 1), motor signs (focal muscle spasm 5, exacerbation of paresis 4, areflexia 1), psychiatric signs (dysphasia 3, disturbance of consciousness 2, euphoria 1, persecutory delusion 1) and muddiness 7. We observed that waxing and waning of side effects correlated tightly with transient cortical penetration of dye in CT and cortical dysfunction mainly slowing of the background activity and slow wave burst in EEG. According to high frequency of side effects in our study, we suggest that a greater incidence of side effects may result when high concentration of Amipaque comes in contact with the cerebral cortex by using an inadequate fluoroscopic table which has only fixed one plane image and rough positioning control. Slow absorption into blood stream may affect appearance and maintenance of side effects. In order to decrease side effects after Amipaque cervical myelography, we propose that we should introduce a mobile rotating chair coupled with high power image and chose C1-C2 lateral route using 1500-1700mgI of Amipaque.

A neuropsychiatric and -psychological update of the crime "profile" and "signature" is a necessary addition to the traditional sociopsychological model likely to miss limbic system dysfunctioning. Thus, occurrence of a brief (c. 20 minutes) limbic seizure has been proposed based on behaviors of 12 white male homicidal loners, who showed a dozen symptoms and signs: Limbic Psychotic Trigger Reaction. Readily overlooked can be (a) a transient psychosis (hallucinations and/or delusions), (b) autonomic hyperactivation (e.g., loss of bladder control, nausea, ejaculation), (c) motiveless, out-of-character, unplanned, and well-remembered homicidal acts, (d) committed with a flat affect (not emotionally or impulsively provoked), (e) typically involving a stranger who happened to provide an objectively harmless and only subjectively important stimulus. (f) Such an individualized stimulus triggered the memory revival of mild to moderate but repeatedly experienced hurts. Such a specific sequence of events implicates the specific mechanism of limbic seizure, "kindling," which does not necessarily involve motor convulsions. Repetition of such limbic episodes with "criminal acts" is conceivable under specific circumstances including cases in which the triggering stimulus is associated with pleasurable delusions (e.g., of grandiose power or wealth) or constitutes a specific aspect of a basic drive motive. For example, eating or sexual activities might be planned but degenerate into a limbic episode with a specific core symptomatology.

Observations on the neurochemistry of dementia with Lewy bodies (DLB) have suggested that cholinesterase inhibitors (ChEIs) might be beneficial in treating some clinical symptoms of DLB. A 24-week, multicenter open-label study was designed to assess the safety and efficacy of the ChEI galantamine in patients with DLB, and an interim analysis of results was performed at 12 weeks. Efficacy analyses were performed on data from 25 patients. Scores on the Neuropsychiatric Inventory (NPI-12) improved (decreased) by 7.52 points over the 12 weeks (marginally significant, p = 0.061). NPI-12 scores decreased by half in 12 of the 25 patients. Highly significant improvement was observed in scores on the NPI-4 subscale (delusions, hallucinations, apathy, and depression: p = 0.003). Scores on the Clinician's Global Impression of Change (CGIC) improved by 0.95 points (significant, p = 0.02). Improvements also were found in secondary efficacy variables, including cognitive, functional, activities of daily living, sleep and confusion assessments. Motor scores, as measured by the UPDRS motor subscale, showed mild improvement, which demonstrates that galantamine has no adverse effect on parkinsonian symptoms. Adverse events generally were transient and of mild-to-moderate intensity. Two of the 25 patients discontinued galantamine because of nausea and anorexia. One serious adverse event was recorded, but it was judged to be unrelated to the study medication.

This review analyses the therapeutic usefulness of Delta(9)-tetrahydrocannabinol and its potential to induce adverse reactions on humans. During the last 30 years an enormous amount of research was carried out resulting in the disclosure of the cannabinoid system in Central Nervous System, with its CB(1) and CB(2) receptors, and the agonist anandamide. Under the clinical point of view, Delta(9)-THC produces some therapeutic benefits which are beyond reasonable doubt. Thus, the effects on nausea/emesis due to cancer chemotherapy, as appetite promoter, on some painful conditions and on symptoms of multiple sclerosis are clearly demonstrated. Delta(9)-THC is not devoid of ill effects. On the cognitive domain it impairs the human capacity to discriminate time intervals and space distances, vigilance, memory and the performance for mental work. On the psychic area Delta(9)-THC may induce unpleasant reactions such as disconnected thoughts, panic reactions, disturbing changes in perception, delusions and hallucinatory experiences. However, the long term effects on the psyche and cognition are not known as there are no reports of prolonged use of Delta(9)-THC. Actually, it has been proposed by WHO that Delta(9)-THC should be rescheduled to schedule IV of the United Nations Convention on Psychotropic Drugs, as it does not constitute a substantial risk to public health and its abuse is rare if at all.

The purpose of this study was to explore the memories of patients who had a short-term admission to the ICU, with a particular focus on dreams, nightmares and confusion. Descriptive data were collected from a target sample of 50 participants, by means of a questionnaire. Following this, eight patients who had completed and returned the questionnaire and had reported hallucinations, dreams or confusion participated in open-ended, semi-structured interviews. Analysis of the data generated by the questionnaire revealed that the most common memories of ICU were anxiety, pain, thirst and nausea. Nightmares, hallucinations and confusion were also common and were reported to be highly distressing. The transcribed interviews were subjected to a thematic analysis. The themes that emerged were, reality and unreality, blackness and colour, powerlessness and purpose, and death. Participants described horrifying paranoid delusions. It is proposed that constant reassurance and explaining every day ICU happenings may assist patients to understand what they are experiencing and loved ones may provide an important link with reality.

Apomorphine, a non-ergot derivative, is a potent, directly acting dopamine receptor agonist with high affinity to D4, lower to D2, D3, D5, the lowest to D1-like dopamine receptors as well as to serotonin and adrenoreceptors. Subcutaneous apomorphine is currently used in Parkinson's disease as an add-on to levodopa therapy or monotherapy for management of sudden, unexpected and refractory to levodopa-induced off state and fluctuation in advanced stage of illness. Many clinical trials have shown markedly (about 50-72%) reduced time of off phases. Other indications include the challenge test for determining the dopaminergic responsiveness. Apomorphine is used subcutaneously either as intermittent rescue injections or continuous infusions. Several other routes - transdermal, sublingual, intranasal, rectal and intravenous infusion - have been tried. Oral administration is not recommended. Apomorphine has rapid onset of antiparkinsonian action, qualitatively comparable to that of levodopa, short duration of action and stable efficacy with usually mild adverse events similar to other dopamine agonists. Domperidone or trimethobenzamide should be introduced before starting apomorphine treatment to reduce occurrence of peripheral adverse events (nausea, vomiting, orthostatic hypotension). Dyskinesias, sleep disturbances, hallucinations, delusion, oedema and yawning can occur, but some side effects are connected only with a specific route (for example skin nodules appearing during subcutaneous administration). Despite its long history, apomorphine is registered and used in only a few countries. Apomorphine warrants wider application in treatment of advanced Parkinson disease but the high cost of the drug, the necessity of concomitant treatment for prevention of side effects and subcutaneous administration restrict its use.

Pituitary apoplexy indicates pituitary adenoma hemorrhage, which could result in acute pituitary insufficiency and mortality. The typical symptoms are headache, visual disturbance, nausea, vomiting, altered mental status, and panhypopituitarism. However, cortisol-induced hyperglycemia and acute delirium could be an initial presentation of a pituitary adenoma hemorrhage with stormy release of the adrenocorticotrophic hormone. A 28-year-old woman presented with severe vomiting, irritable state, and delusion. She had medical history of irregular menstrual cycles and marked body weight gain after her second childbirth 8 years ago. She was diagnosed of diabetic ketoacidosis 2 days before this visiting at local medical department. On physical examination, Cushing appearance without definite neurological deficit was disclosed. Further blood tests revealed high blood sugar, cortisol, and adrenocorticotrophic hormone levels without evidence of diabetic ketoacidosis. The brain computed tomography and magnetic resonance imaging showed pituitary macroadenoma and pituitary hemorrhage. Cushing disease with pituitary apoplexy was then diagnosed. Conservative management with delayed neurosurgery was applied. The patient became clear with normalized cortisol and blood sugar levels soon after. Follow-up computed tomography scan of the brain revealed no progression of tumor bleeding or mass effect. To our knowledge, pituitary apoplexy associated with cortisol-induced hyperglycemia and acute delirium has never been reported before. This case reminds us of pituitary apoplexy and its rare manifestations.

The prolactin, cortisol and growth hormone (GH) responses to intravenous administration of 25 mg clomipramine (CMI) were studied in young male psychotic patients who had never received neuroleptics and suffered from schizophrenia (13 patients), delusional disorder (three patients) or schizoaffective disorder (one patient). The test was repeated after 1 month in 16 patients who were hospitalized and treated with haloperidol in doses appropriate for best clinical response (range: 7.5-40 mg daily). Symptomatology was assessed by the Brief Psychiatric Rating Scale (BPRS). There was no association of the side effects caused by the administration of CMI (nausea and emesis) to the GH responses. The side effects appeared significantly less in the after treatment trials. Treatment with haloperidol did not influence the response patterns of the three hormones. An indication that high haloperidol doses may inhibit the prolactin response to CMI was obtained when the data were compared between low (7.5-10 mg/day, mean 9.7) and high (15-40 mg/day, mean 22.0) dose subgroups. Significant positive correlations were found between the prolactin and cortisol responses to CMI in the drug-free state, and the scores in the positive symptoms subscale of the BPRS. The degree of improvement did not correlate to any of the hormonal data.

Pramipexole is a nonergolinic dopamine agonist, with high affinity for the D2 subfamily of dopamine receptors. Pramipexole is efficacious for the symptomatic treatment of early Parkinson's Disease (PD) and its early use, before that of levodopa can delay the emergence of levodopa-related motor complication. Dosage should be increased gradually from a starting dose of 0.375 mg/day up to a maximum of 4.5 mg/day in equally divided doses taken three times per day with pramipexole immediate-release or equivalent daily dosages once-daily with pramipexole extended-release. Pramipexole can also improve depressive symptoms and possibly health-related quality of life in PD. Nonetheless, its use is not devoid of tolerability problems. While peripheral adverse drug reactions, such as nausea, vomiting or orthostatic hypotension, can be effectively treated and usually pose few problems to most patients, neuropsychiatric events can seriously limit the use of pramipexole in some cases. Indeed, excessive daytime somnolence, impulse-control disorders, hallucinations or delusions can severely affect patients, causing important personal or social handicap. Patients should be informed about the risk of such neuropsychiatric complications and their presence should be actively detected at each consultation. More effort will have to be put into further studying the risk-benefit ratio of pramipexole and other dopamine agonists in the treatment of early PD.
