[Dementia and psychiatric service]. / Demens og psykiatrisk service.

The study objective was to describe the service provision in geriatric psychiatry in 1997 and the trends in admission patterns for the elderly to psychiatric hospitals in Denmark from 1988 to 1996. Information concerning admission pattern was obtained from the Danish Psychiatric Case Register. The information on the supply of geriatric psychiatric services was collected by a questionnaire to the individual geriatric psychiatric departments. All geriatric psychiatric departments in Denmark have been identified. The number of demented patients admitted to psychiatric hospitals decreased considerably as did the length of stay for demented patients admitted from 1988 to 1996. For all other diagnoses the number of admissions increased in the same period. Four counties out of 14 did not have a special unit for geriatric psychiatry. There were considerable geographical variations in supply as well as target groups in the counties that supplied geriatric psychiatric service. The unequal access to geriatric psychiatric services and variations in target groups underlines the need for a discussion of future directions for this service provision.

[The elderly in general psychiatry]. / Aeldre i almenpsykiatrien.

The Danish National Board of Health recommends that the counties offer psychogeriatric services. The target group for geriatric psychiatry in the County of North Jutland only concerns elderly people with severe dementia. It has been our aim to describe and discuss the geriatric psychiatric supply of services and admission pattern for elderly with psychiatric morbidity in the County of North Jutland. We have made a cross-sectional study of all patients referred to the general and psychogeriatric service in 1997. In psychogeriatric service 40 of 46 referrals were dealt with as out-patient contact. In general psychiatry the 57 referrals resulted in 33 admissions of which 31 were acute. There is a high number of acute admissions in general psychiatry. The County of North Jutland does not have a suitable service for diagnostic work-up and treatment of people with possible to moderate dementia.

[Late abortions in the county of Northern Jutland]. / Sene aborter i Nordjyllands Amt.

Applications for termination of pregnancy beyond 12 weeks have been evaluated for the period 1992-1993 in the County of Northern Jutland. During this period the number of abortions performed later than 12 weeks of pregnancy has been reduced compared to the findings in 1986, while the total number of abortions performed in the county is unchanged. Abortions allowed on genetic indications have increased by 100% a year. Young women below 20 years of age still represent one third of late applicants for abortion. The amount of errors committed by doctors contributing to late applications shows a decreasing tendency. The use of ultrasonic scanning is increasing.

Risperidone versus perphenazine in the treatment of chronic schizophrenic patients with acute exacerbations.

Risperidone (RIS), a new neuroleptic with 5-HT2- and dopamine D2 receptor-blocking properties, was compared with perphenazine (PER) in a double-blind, multicentre, parallel-group study in 107 chronic schizophrenics with acute exacerbation. RIS 5-15 mg or PER 16-48 mg daily was given for 8 weeks. Psychopathology was assessed with the Positive and Negative Syndrome Scale (PANSS) and Clinical Global Impression. Seventy-eight patients completed the trial; there was an equal number of dropouts on both drugs. The mean daily dose at endpoint was 8.5 mg RIS and 28 mg PER. The reduction in total PANSS score to endpoint did not differ significantly, although there was a tendency in favour of RIS. The number of patients with predominantly negative symptoms who showed at least 20% reduction in total PANSS score was significantly larger in the RIS group. Furthermore, the number of patients showing at least 20% reduction in Brief Psychiatric Rating Scale (BPRS) score (BPRS being a subscale of PANSS) was significantly larger in the RIS group. The hostility cluster of BPRS improved more on RIS than on PER in the endpoint analysis. The overall prevalence of side effects was fairly similar in the two groups.

A controlled Nordic multicentre study of zuclopenthixol acetate in oil solution, haloperidol and zuclopenthixol in the treatment of acute psychosis.

Zuclopenthixol acetate--a new injectable formulation with a duration of action of 2-3 days--was compared with conventional intramuscular and oral formulations of haloperidol and zuclopenthixol in the initial treatment of acutely disturbed, psychotic patients. The patients were stratified into 3 diagnostic categories: acute psychoses (48 patients), mania (22 patients), and exacerbation of chronic psychoses (73 patients). The patients were rated on the Brief Psychiatric Rating Scale (BPRS), the Bech-Rafaelsen Mania Rating Scale (BRMAS) (only manic patients) and globally on the Clinical Global Impression (CGI). The study was an open, randomized multicentre trial with a 6-day treatment period. The zuclopenthixol acetate patients received 1-4 doses, the haloperidol patients 1-26 and the zuclopenthixol patients 1-22 doses. The assessments on the CGI showed that all 3 treatments caused a clear reduction of the severity of illness scores in all 3 diagnostic categories, with no differences between treatments. The ratings of the acute and chronic psychotic patients on the BPRS also showed significant reductions in scores with no differences between treatments. All 3 treatments caused a rapid remission of symptoms on the BRMAS. Haloperidol induced hypokinesia in significantly more patients than zuclopenthixol acetate after 24 h. Later there were no significant differences between treatments. Zuclopenthixol acetate fulfils many desires for an amended neuroleptic formulation for the initial treatment of acutely disturbed psychotic patients.

A double blind comparative multicentre study of remoxipride and haloperidol in schizophrenia.

Seventy-two patients fulfilling the DSM-III criteria for schizophrenia and schizophreniform psychosis were admitted to a multicentre, double-blind controlled study to evaluate the efficacy and safety of remoxipride in comparison to haloperidol. The mean daily dose of remoxipride at the end of treatment was 353 mg and of haloperidol, 11 mg. Patients were assessed each week on the Brief Psychiatric Rating Scale (BPRS), the Clinical Global Impression (CGI) and the symptoms checklist. No significant differences in efficacy were found between the two treatments. The median total BPRS score in the remoxipride group was 25 at start of active treatment and 17 at the last valid rating (n = 31). For the haloperidol group the corresponding figures were 24 and 15 (n = 29). According to the CGI, 40% of remoxipride patients and 50% of haloperidol patients were much or very much improved. Treatment-emergent extrapyramidal symptoms, such as akathisia and rigidity, occurred significantly more frequently, and were more severe during treatment with haloperidol than with remoxipride (p = 0.012 and 0.024, respectively). Haloperidol-treated patients reported significantly more drowsiness and increased sleep during treatment (p = 0.026 and 0.012, respectively). No statistically significant differences were seen in endocrine or autonomic symptoms. Remoxipride seemed to be as effective as haloperidol, had a lower frequency of side effects, and was used safely in the dose range 150-600 mg/day.

Zuclopenthixol acetate in Viscoleo--a new drug formulation. An open Nordic multicentre study of zuclopenthixol acetate in Viscoleo in patients with acute psychoses including mania and exacerbation of chronic psychoses.

Eighty-three acutely disturbed, psychotic patients were included in an open multicentre study. The aim of the study was to evaluate the clinical effect of zuclopenthixol acetate in Viscoleo (CPT-A). Each patient received from one to four intramuscular injections of CPT-A during the 6-day study period. The duration of action after one injection was between 2 and 3 days and doses from 50 mg to 150 mg were sufficient for most patients. Treatment with CPT-A caused a pronounced and rapid reduction of the psychotic symptoms. At the end of the 6-day test period the mean total score on BPRS in acute non-manic and exacerbated chronic patients was reduced by more than 50 per cent. In acute manic patients the mean total score on BRMS was reduced by 57 per cent already 1 day after injection. Rapidly after the injection of CPT-A a useful short-acting sedation can be expected, but the risk for oversedation even after a second injection is low. The frequency of unwanted effects, including extrapyramidal reactions, was low and the severity of symptoms was most often mild. With a rapid onset of action, a duration of effect of 2 to 3 days, and few and mild side effects, CPT-A offers advantages over the neuroleptic preparations conventionally used in the initial treatment of acutely disturbed, psychotic patients.

Loxapine versus perphenazine in psychotic patients. A double-blind, randomized, multicentre trial.

A double-blind, randomized, multicentre trial was carried out in 47 psychotic patients to evaluate the efficacy of oral treatment with loxapine compared with perphenazine. In total, 22 patients were included in diagnostic Group I (cases of acute schizophrenia and psychogenic (reactive) psychoses). The average maximum daily dose was 60.0 mg in the loxapine group and 36.8 mg in the perphenazine group. After 3-weeks' treatment, no significant differences were found between the two treatment groups according to the Brief Psychiatric Rating Scale (BPRS), Clinical Global Impression (CGI) Scale or side-effect records. Twenty-five patients were included in diagnostic Group II (cases of chronic schizophrenia). The average daily dosage was 81.1 mg in the loxapine group and 90.1 mg in the perphenazine group. After 10 to 12-weeks' treatment, no significant differences between the two treatment groups could be found according to BPRS, CGI scale, Nurses' Observation Scale for In-patient Evaluation (NOSIE) or side-effect records. The diastolic blood pressure (lying and standing) tended to increase slightly in both treatment groups. In conclusion, it was found that loxapine and perphenazine seemed to be equally effective and, based on experience with parenteral loxapine treatment, it is suggested that further investigation of oral loxapine should be carried out in psychotic patients in whom agitation is a feature.
