Olanzapine Versus Haloperidol for Treatment of Delirium in Patients with Advanced Cancer: A Phase III Randomized Clinical Trial.

Background: Treatment of delirium often includes haloperidol. Second-generation antipsychotics like olanzapine have emerged as an alternative with possibly fewer side effects. The aim of this multicenter, phase III, randomized clinical trial was to compare the efficacy and tolerability of olanzapine with haloperidol for the treatment of delirium in hospitalized patients with advanced cancer.

Accuracy of the Delirium Observational Screening Scale (DOS) as a screening tool for delirium in patients with advanced cancer.

Background: The Delirium Observation Screening Scale (DOS) was developed to facilitate early recognition of delirium by nurses during routine clinical care. It has shown good validity in a variety of patient populations, but has not yet been validated in hospitalized patients with advanced cancer, although the DOS is commonly used in this setting in daily practice. The aim of this study was to evaluate the accuracy of the DOS in hospitalized patients with advanced cancer using the revised version of the Delirium Rating Scale (DRS-R) as the gold standard.

Objective: To describe medication use in the last week of life for patients dying in hospital, hospice, and home settings in the Netherlands.

Predictors of Persistent Neuropathic Pain--A Systematic Review.

Background: Characterization of the prognostic variables for persistent neuropathic pain (PNP) remains incomplete despite multiple articles addressing this topic. To provide more insight into the recovery and prognosis of neuropathic pain, high-quality data are required that provide information about the predictors that contribute to the development of PNP.

Objective: To determine the methodological quality of studies about predictors for PNP and to summarize findings of predictors found in high-quality studies.

Pain in dementia: prevalence and associated factors: protocol of a multidisciplinary study.

Background: Pain is a common problem in people with dementia, however the exact prevalence of pain in dementia subtypes, e.g. Alzheimer's Disease (AD), Vascular Dementia (VaD), Frontotemporal Dementia (FTD) and dementia with Lewy Bodies (DLB), is unknown, as is the relation between pain and the different subtypes of dementia.

The palliative performance scale applied in high-care residential hospice: a retrospective study.

Background: The Palliative Performance Scale (PPS) is a tool that is widely used to predict end of life. In Ontario, Canada, the PPS is used to mark the terminal phase of life and eligibility for terminal care.

Objective: The aim of this retrospective study was to confirm that a PPS level of 40% can be used as a marker for the terminal phase of life.

Continuous palliative sedation: not only a response to physical suffering.

Background: Palliative sedation is a medical intervention aimed at relieving symptoms that can no longer be controlled by conventional treatment. Ample knowledge is available regarding the nature of such symptoms, but there is no in-depth information regarding how health care workers decide about palliative sedation.

Objective: The study objective was to investigate considerations concerning the indications for continuous palliative sedation (CPS) and issues that influence these considerations.

A favorable course of palliative sedation: searching for indicators using caregivers' perspectives.

Objective: Comparing characteristics of a favorable sedation course during palliative sedation to a less favorable course based on the reports Dutch physicians and nurses.

Results: Cases identified as having a favorable sedation course less often concerned a male patient (P = .019 nurses' cases), reached the intended sedation depth significantly quicker (P < .

Intravenous magnesium for chronic complex regional pain syndrome type 1 (CRPS-1).

Objective: To assess the effects of intravenous administration of magnesium on complex regional pain syndrome type 1 (CRPS-1), a randomized double-blind placebo-controlled trial was performed.

Methods: Fifty-six patients with CRPS-1 (International Association for the Study of Pain Orlando criteria) received MgSO(4) 70 mg/kg or placebo (NaCl 0.9%) in 4 hours over 5 consecutive days.

An overview of predictors for persistent neuropathic pain.

Neuropathic pain (NP) is a pain arising as a direct consequence of a lesion or disease affecting the somatosensory system. A variety of factors associated with the development of persistent NP have been suggested. The goal of the present article is to provide an overview of current knowledge about prognostic factors for persistent NP.

Oxidative stress in Complex Regional Pain Syndrome (CRPS): no systemically elevated levels of malondialdehyde, F2-isoprostanes and 8OHdG in a selected sample of patients.

Exaggerated inflammation and oxidative stress are involved in the pathogenesis of Complex Regional Pain Syndrome (CRPS). However, studies assessing markers for oxidative stress in CRPS patients are limited. In this study, markers for lipid peroxidation (malondialdehyde and F2-isoprostanes) and DNA damage (8-hydroxy-2-deoxyguanosine) were measured in nine patients (mean age 50.

Palliative sedation: reliability and validity of sedation scales.

Context: Observer-based sedation scales have been used to provide a measurable estimate of the comfort of nonalert patients in palliative sedation. However, their usefulness and appropriateness in this setting has not been demonstrated.

Objectives: To study the reliability and validity of observer-based sedation scales in palliative sedation.

Pressure during decision making of continuous sedation in end-of-life situations in Dutch general practice.

Background: Little is known about pressure from patients or relatives on physician's decision making of continuous palliative sedation. We aim to describe experienced pressure by general practitioners (GPs) in cases of continuous sedation after the introduction of the Dutch practice guideline, using a questionnaire survey.

Methods: A sample of 918 Dutch GPs were invited to fill out a questionnaire about their last patient under continuous sedation.

Considerations of physicians about the depth of palliative sedation at the end of life.

Background: Although guidelines advise titration of palliative sedation at the end of life, in practice the depth of sedation can range from mild to deep. We investigated physicians' considerations about the depth of continuous sedation.

Methods: We performed a qualitative study in which 54 physicians underwent semistructured interviewing about the last patient for whom they had been responsible for providing continuous palliative sedation.

The use of observational scales to monitor symptom control and depth of sedation in patients requiring palliative sedation: a systematic review.

Background: Palliative sedation is the intentional lowering of consciousness of a patient in the last phase of life to relieve suffering from refractory symptoms such as pain, delirium and dyspnoea.

Aim: In this systematic review, we evaluated the use of monitoring scales to assess the degree of control of refractory symptoms and/or the depth of the sedation.

Design: A database search of PubMed and Embase was performed up to January 2010 using the search terms 'palliative sedation' OR 'terminal sedation'.

Continuous palliative sedation for cancer and noncancer patients.

Context: Palliative care is often focused on cancer patients. Palliative sedation at the end of life is an intervention to address severe suffering in the last stage of life.
