RESUMEN

Background: Extra-pyramidal side effects, sexual dysfunctions and hyperprolactinaemia are major side effects with the use of antipsychotic medications that impede treatment adherence leading to relapse, increased cost of care and rehospitalization among patients with schizophrenia on antipsychotic medications. The study aims to compare the prevalence of extra-pyramidal side effects (EPSE), sexual dysfunctions (SD) and hyperprolactinaemia (HPRL) among patients with schizophrenia spectrum disorders on typical and atypical antipsychotic medications. The secondary aim is to determine if any associations exist between extra-pyramidal side effects, sexual dysfunctions and hyperprolactinaemia. Methodology: A cross-sectional hospital-based survey involving 209 patients with schizophrenia were interviewed with structured instruments for the assessment of sexual dysfunction, EPSE and the estimation of serum prolactin was done using Enzyme-linked Immunosorbent Assay. Frequencies and Chi-square analysis were used to compare differences in EPSE, SD & HPRL. Results: The study revealed non-statistically significant differences as a group between typical and atypical antipsychotic medication in terms of extra-pyramidal side effects, sexual dysfunction and hyperprolactinaemia. However, a significant association was observed when individual drugs were compared with haloperidol causing the highest frequency of hyperprolactinaemia (χ 2 = 14.9, P = 0.011). A significant relationship between sexual dysfunction and hyperprolactinaemia, sexual dysfunction and extra-pyramidal side effects as well as extra-pyramidal and hyperprolactinaemia was found when individual items for sexual functionin were used. Conclusion: The significant relationships between sexual dysfunction only in the domains of sexual desire and arousal with hyperprolactinaemia and extrapyramidal side effects as well as hyperprolactinaemia with extrapyramidal side effects point to a common anti-dopaminergic activity of antipsychotics via different pathways. Prospective studies among a larger sample of patients with schizophrenia are needed to unfold these relationships.

RESUMEN

The neuroleptic malignant syndrome is a rare, life-threatening idiosyncratic reaction to neuroleptic medication. The use of newer antipsychotics combined with its rare incidence has made NMS seem as a complication of the past. Here we report a patient in his early 20s suffering from a psychotic disorder developing a life-threatening neuroleptic malignant syndrome on an inpatient psychiatric ward in Canada without the characteristic overt change in autonomic stability. We review the clinical characteristics to facilitate the early recognition of neuroleptic malignant syndromes and discuss why this condition still is highly relevant for practising physicians.

RESUMEN

OBJECTIVES: Extrapyramidal side effects (EPSEs) are serious potentially reversible side effects of antipsychotic and other medications that can cause distress for patients. A core principle of palliative care involves optimising quality of life. If side effects of medications are burdensome, it is imperative that we address this issue. The aim of the study was to determine and describe the burden of EPSEs in a specialist inpatient unit. METHODS: Consenting patients who met inclusion criteria were assessed for EPSE with two validated screening tests, the Modified Simpson-Angus Scale (MSAS) and Barnes Akathisia Rating Scale (BARS). Additional demographic data were collected including medications associated with EPSE, previous history of EPSE and known risk factors that may predispose a patient to EPSE. RESULTS: 43% inpatients met inclusion criteria. At least 66% of patients were taking regular medications associated with EPSE. Of those, 25% were taking ≥2 medications associated with EPSE. The MSAS revealed 50% scored <3, 44% scored 3-5% and 6% scored 6-11. Seven patients had at least one 'not rateable score'. In the BARS (sitting±standing), 94% scored 0/5 and 6% scored 1/5. 12.5% of participants were able to stand for 2 min to complete the BARS. CONCLUSIONS: 50% screened positive for EPSE. The complete BARS was unsuitable for most participants. The MSAS, while allowing a not rateable score, may underestimate EPSE. The frailty of an inpatient unit population impacts on applicability of screening tools and may therefore underestimate the burden of the problem in this population. Development of a population-specific screening tool warrants further investigation.

RESUMEN

OBJECTIVE: Our objective was to report and describe a case of quetiapine-induced dystonia in an older lady with psychosis. Quetiapine is a second-generation antipsychotic and known to be rare in causing extrapyramidal side effects with rates similar to placebo. CONCLUSIONS: There have been few documented cases of quetiapine-induced dystonia. It is important to be vigilant and consider the development of dystonia in patients who may not fit the typical risk profile.

RESUMEN

OBJECTIVE: The aim of this paper is to present a case and discussion illustrating the limitations in the evidence base to guide practice in relationship to managing severe aggression in people with dementia. It also calls attention to the association between haloperidol use and increased mortality in dementia. METHOD: Case report and review of the literature. RESULTS: A 60-year-old man with rapidly progressive frontotemporal dementia complicated by severe aggression was managed in specialised psychogeriatric services and high-dose haloperidol was used. This treatment decision was made following literature review, consultation with experts and a detailed risk-benefit analysis. Unfortunately, his physical condition deteriorated swiftly and he died soon after. CONCLUSIONS: Haloperidol is associated with increased mortality in patients with dementia. This case exposes the difficulties in managing severe aggression in dementia, with few safe and effective treatment options and a lack of consensus guidance in the area of very severe aggression in dementia.
