Palliative sedation (sedation to unconsciousness) as an option of last resort for intractable end-of-life distress has been the subject of ongoing discussion and debate as well as policy formulation. A particularly contentious issue has been whether some dying patients experience a form of intractable suffering not marked by physical symptoms that can reasonably be characterized as "existential" in nature and therefore not an acceptable indication for palliative sedation. Such is the position recently taken by the American Medical Association. In this essay we argue that such a stance reflects a fundamental misunderstanding of the nature of human suffering, particularly at the end of life, and may deprive some dying patients of an effective means of relieving their intractable terminal distress.

Opioid analgesics are the drugs of choice for the treatment of moderate to severe acute and cancer pain. Although their role in the management of chronic pain not related to cancer is controversial, there is increasing evidence for their benefit in certain patient populations. ⋯ Wisconsin physicians who responded to this survey held many misconceptions about the prescribing of opioids. Such views, coupled with a lack of knowledge about laws and regulations governing the prescribing of controlled substances, may result in inadequate prescribing of opioids with resultant inadequate management of pain.

Randomized Controlled Trial
Safety and Efficacy of Dietary Agmatine Sulfate in Lumbar Disc-associated Radiculopathy. An Open-label, Dose-escalating Study Followed by a Randomized, Double-blind, Placebo-controlled Trial.
Objective. Agmatine, decarboxylated arginine, was shown in preclinical studies to exert efficacious neuroprotection by interacting with multiple molecular targets. This study was designed to ascertain safety and efficacy of dietary agmatine sulfate in herniated lumbar disc-associated radiculopathy. ⋯ Dietary agmatine sulfate is safe and efficacious treatment for alleviating pain and improving quality of life in lumbar disc-associated radiculopathy. Study Registration. ClinicalTrials.gov Protocol Registration System Identifier: NCT00405041.

Randomized Controlled Trial Comparative Study
Comparing the psychometric properties of the Checklist of Nonverbal Pain Behaviors (CNPI) and the Pain Assessment in Advanced Dementia (PAIN-AD) instruments.
To examine and compare the psychometric properties of two common observational pain assessment tools used in persons with dementia. ⋯ Despite earlier studies supporting the reliability and validity of the CNPI and the PAINAD, findings from the current study indicate that these measures warrant further study with clinical users, should be used cautiously both in research and clinical settings and only as part of a comprehensive approach to pain assessment.

Randomized Controlled Trial Comparative Study
Comparison of cutaneous anesthetic effect of 8% lidocaine spray with lidocaine patch using current perception threshold test.
A lidocaine patch is often used for topical anesthesia prior to venipuncture, but needs to be applied for several hours before the puncture, and the site is fixed. A metered-dose lidocaine pump spray could be used to produce cutaneous topical anesthesia. In this study, we compared the anesthesia between the spray and the patch. ⋯ Similar to the lidocaine patch, the lidocaine spray produces cutaneous weak anesthesia at 30 minutes after treatment. The spray seems to produce local anesthesia faster than the patch.
