Increased health care utilization and increased antiretroviral use in HIV-infected individuals with mental health disorders.

OBJECTIVES: The aims of the study were to describe the prevalence and associations of mental health disorder (MHD) among a cohort of HIV-infected patients attending the Victorian HIV/AIDS Service between 1984 and 2000, and to examine whether antiretroviral therapy use or mortality was influenced by MHD (defined as a record of service provision by psychiatric services on the Victorian Psychiatric Case Register). It was hypothesized that HIV-positive individuals with MHD would have poorer treatment outcomes, reduced responses to highly active antiretroviral therapy (HAART) and increased mortality compared with those without MHD. METHODS: This is a retrospective cohort of 2981 individuals (73% of the Victorian population diagnosed with HIV infection) captured on an HIV database which was electronically matched with the public Victorian Psychiatric Case Register (VPCR) (accounting for 95% of public system psychiatry service provision). The prevalence, dates and recorded specifics of mental health disorders at the time of the electronic match on 1 June 2000 are described. The association with recorded MHD, gender, age, AIDS illness, HIV exposure category, duration and type of antiviral therapy, treatment era (prior to 1986, post-1987 and pre-HAART, and post-HAART) on hospitalization and mortality at 1 September 2001 was assessed. RESULTS: Five hundred and twenty-five individuals (17.6% of the Victorian HIV-positive population) were recorded with MHD, most frequently coded as attributable to substance dependence/abuse or affective disorder. MHD was diagnosed prior to HIV in 33% and, of those diagnosed after HIV, 93.8% were recorded more than 1 year after the HIV diagnosis. Schizophrenia was recorded in 6% of the population with MHD. Hospitalizations for both psychiatric and nonpsychiatric illness were more frequent in those with MHD (relative risk 5.4; 95% confidence interval 3.7, 8.2). The total number of antiretrovirals used (median 6.4 agents vs 5.5 agents) was greater in those with MHD. When adjusted for antiretroviral treatment era, HIV exposure category, CD4 cell count and antiretroviral therapy, survival was not affected by MHD. CONCLUSIONS: MHD is frequent in this population with HIV infection and is associated with increased healthcare utilization but not with reduced survival.

A 12-month follow up of the implementation of clinical indicators in a consultation-liaison service.

OBJECTIVES: This paper reviews the use of clinical indicators in a consultation-liaison (C-L) service over a 12-month period at the Royal Melbourne Hospital, Melbourne, Australia. METHOD: Clinical indicators and C-L data were collected during the 1999 calendar year. A review of the process was conducted during and after completion of the 12-month period. RESULTS: The system was found to be practical and useful. The use of clinical indicators led to the identification of problems and stimulated effective interventions. The use of the clinical indicators was associated with improvement in communication between C-L staff, parent units and practitioners providing follow-up. CONCLUSIONS: The implementation of a database and clinical indicators was a useful addition to the C-L service. The use of clinical indicators was effective in improving clinical performance. These benefits need to be balanced against increased administrative burden.

Suicidal behaviour in people with HIV/AIDS: a review.

OBJECTIVE: To review the existing literature on suicidal behaviour in people with HIV/AIDS infection. METHOD: A search on the Index Medicus/MEDLINE database was performed, for articles that investigated and/or reviewed suicidal behaviour in people with HIV at any stage of the illness. Only articles written in English were used in this review. RESULTS: Most studies have been done on homosexual/bisexual groups, with little data available for heterosexual populations or women. Studies show an increased rate of suicidal ideation, suicide attempts and completed suicide in individuals with HIV/AIDS. Of note, there is a high prevalence of psychiatric illness and substance abuse in those with suicidal behaviour. CONCLUSIONS: The increased rate of suicidal behaviour in HIV-infected persons is consistent with findings in other medically ill groups with chronic, life-threatening disorders. However, assessment of any possible direct effect of HIV/AIDS on suicidal behaviour is confounded by methodological limitations of many of the studies. More longitudinal studies encompassing other affected groups including heterosexual populations and women are needed to elucidate the relationship between suicidal behaviour and HIV/AIDS.

The development of clinical indicators for a consultation-liaison service.

OBJECTIVE: The aim of this paper is to describe the development and implementation of clinical indicators in the consultation-liaison service at Royal Melbourne Hospital (RMH). METHOD: A working party lead by the University of Melbourne was established in 1998 to develop clinical indicators and a database for the RMH consultation-liaison service. Core parameters for measuring service functioning and six clinical indicators were developed. The system was implemented using a data collection form and computerised database operating within a system of regular clinical reviews. RESULTS: The clinical indicators, database and review system were found to be a feasible, useful and efficient addition to a consultation-liaison service at a major general hospital. CONCLUSIONS: Clinical indicators may be used within specialist psychiatry services to enhance clinical care and aid in service development and teaching.

The role of SPECT scanning in a neuropsychiatry unit.

OBJECTIVES: Single photon emission computerised tomography (SPECT) studies allow the assessment of cerebral blood flow and have been increasingly used as a clinical tool in neurology and neuropsychiatry. This paper examines the contribution of SPECT to the clinical management of patients with neuropsychiatric disorders, in particular patients with atypical or early onset dementia. METHOD: All patients admitted to an eight-bed neuropsychiatry unit in a general hospital setting who had undergone SPECT scanning over a 15-month period were reviewed. Information was collected on clinical diagnosis, neuropsychological testing, structural neuroimaging and SPECT. RESULTS: SPECT abnormalities were present in 88% of patients. The pattern of SPECT abnormality was concordant with structural neuroimaging in 65% of patients and concordant with neuropsychological testing in 82% of patients. The sensitivity and specificity of SPECT was 89%/79% for Alzheimer's disease and 56%/79% for frontotemporal dementias. CONCLUSIONS: SPECT results must be interpreted in the context of other clinical and diagnostic assessments. In no single case was the clinical diagnosis made solely on the basis of a SPECT result. SPECT was of maximum clinical use in the diagnosis of frontotemporal dementias and in confirming the diagnosis of Alzheimer's dementia. SPECT was valuable in Lewy body dementia, vascular dementia and head injury. Its clinical utility in other psychiatric disorders remains unclear.

Evaluation of contamination of used disposable contact lenses by Acanthamoeba.

PURPOSE: The purpose of this study was to evaluate the contamination of used disposable soft contact lenses with Acanthamoeba. METHODS: We evaluated 51 consecutive disposable soft contact lens wearers in a prospective study. Before their check-up visits, patients were offered a free new contact lens in exchange for donating their old one. The used contact lenses (n = 102) were then removed and placed in culture medium for Acanthamoeba. We subsequently investigated patterns of wear and hygiene habits. RESULTS: The mean age of this population was 32.6 +/- 11.0 years. The average time of disposable soft contact lens wear was 13.7 hours per day. The contact lenses were disinfected daily with commercial solutions. Twenty-five (49.0%) subjects did not clean their lens cases properly. Acanthamoeba was not isolated from any of the 102 lenses. CONCLUSIONS: There were no cases of Acanthamoeba contamination in a small population of disposable soft contact lens wearers who regularly disinfected their lenses with standard commercially available contact lens solutions.

Successful medical treatment of Acanthamoeba keratitis.

PURPOSE: To describe the outcome of a series of Acanthamoeba keratitis treated with a similar regimen. METHODS: All cases diagnosed with Acanthamoeba keratitis in a referral centre from June 1994 through June 1997 were included. Diagnosis of Acanthamoeba keratitis was based in clinical presentation and laboratory results. Positive laboratory identification of Acanthamoeba from corneal scraping or contact lens was required, unless the patient had very characteristic symptoms (severe pain) and signs of the infection, including perineural infiltrates. Initial intensive treatment included topical polyhexamethylene biguanide (PHMB) 0.02%, propamidine isothionate 0.1% and broad-spectrum antibiotics. The treatment was gradually tapered. After documented response to anti-acanthamoeba therapy, topical steroids were introduced; they were discontinued before cessation of the anti-Acanthamoeba regimen. RESULTS: Six males and four females, with a mean age of 30.0 +/- 7.4 years were included in this study. All cases wore contact lenses. On presentation all cases had severe pain, and epitheliopathy was associated with stromal infiltrate in most (seven of ten) cases. Four patients had anterior uveitis. Perineural infiltrates were present in three cases and ring infiltrate in one patient. Anti-amoebic treatment was started 12.7 +/- 7.2 days after beginning of symptoms. The clinical response to therapy was very satisfactory in all patients. Within two to three weeks all patients had remarkable lessening of pain and photophobia, and improvement of clinical signs. At two to three months, visual acuity had improved in all patients. Two patients required penetrating keratoplasty for visual rehabilitation. CONCLUSION: The use of PHMB and propamidine cured all cases of Acanthamoeba keratitis. Cautious introduction of steroids was associated with expedited resolution of inflammation and provided symptomatic relief.

Taurolidine peritoneal lavage as prophylaxis against infection after elective colorectal surgery.

A total of 300 patients undergoing elective colorectal surgery over a 3-year period were randomly assigned to receive intraoperative peritoneal lavage with either taurolidine or saline. Culture swabs were taken from the region of surgery before and after lavage and the development of postoperative infection monitored. Of the positive culture swabs before lavage, a significantly higher proportion were negative after lavage with taurolidine than after that with saline. However, there was no difference in the incidence of postoperative infection between groups, suggesting that taurolidine intraoperative peritoneal lavage confers no clinical benefit over that with saline.

Diffuse Lewy body disease and progressive dementia in a young woman.

This report details the emergence of a progressive parkinsonian syndrome, dementia and behavioural disturbance in a 33 year-old woman which can be dated to the delivery of her first child. The findings of this case indicate that cortical Lewy body disease should be considered in any patient with temporoparietal dementia and idiopathic Parkinson's disease irrespective of the age of onset.

Neuroleptic toxicity syndromes: a clinical spectrum.

The neuroleptic malignant syndrome (NMS) has undergone a number of changes since it was first described in the 1960s. This paper presents a review of these changes from the traditional approach of rigid categorization through the more flexible operational definitions to a spectrum of neuroleptic toxicity. This spectrum spans neuroleptic-induced extrapyramidal side effects, possible stages of neuroleptic toxicity, and the full blown neuroleptic malignant syndrome. Different theoretical concepts of the syndrome have contributed to diagnostic confusion among clinicians and thus to difficulties in management. The concept of a spectrum of neuroleptic toxicity provides a coherent theoretical base for understanding NMS and thus allows for more rapid identification of the potential threat of NMS. Three cases are presented and discussed to highlight the utility of the concept of a clinical spectrum.
