Acetaminophen (paracetamol) is a widely used nonopioid, non-NSAID analgesic that is effective against a variety of pain types, but the consequences of overdose can be severe. Because acetaminophen is so widely available as a single agent and is increasingly being formulated in fixed-ratio combination analgesic products for the potential additive or synergistic analgesic effect and/or reduced adverse effects, accidental cumulative overdose is an emergent concern. This has rekindled interest in the sites, processes, and pharmacokinetics of acetaminophen oral absorption and the clinical factors that can influence these. ⋯ Although acetaminophen does not have the abuse potential of opioids or the gastrointestinal bleeding or organ adverse effects of NSAIDs, excess amounts can produce serious hepatic injury. Thus, an understanding of the sites and features of acetaminophen absorption--and how they might be influenced by factors encountered in clinical practice--is important for pain management using this agent. It can also provide insight for design of formulations that would be less susceptible to clinical variables.

Review Meta Analysis
Cost-effectiveness of Acupuncture for Chronic Nonspecific Low Back Pain.
Cost-effectiveness is a major criterion underpinning decisions in mainstream health care. Acupuncture is increasingly used in patients with chronic lower back pain (LBP), but there is a lack of evidence on cost-effectiveness. The objective of this study was to assess the cost-effectiveness of acupuncture in alleviating chronic LBP either alone or in conjunction with standard care compared with patients receiving routine care, and/or sham. ⋯ When comorbid depression is alleviated at the same rate as pain, cost is around $18,960 per DALY avoided. Acupuncture as a substitute for standard care was not found to be cost-effective unless comorbid depression was included. According to the WHO cost-effectiveness threshold values, acupuncture is a cost-effective treatment strategy in patients with chronic LBP.

Headache Impact Test (HIT-6) measures the impact headaches in a 1-month period. We validated the Persian translation of HIT-6, compared the HIT-6 psychometric analysis between migraine and tension-type headache (TTH) patients, and evaluated the capability of HIT-6 to differentiate between TTH, chronic migraine, and episodic migraine. ⋯ Persian HIT-6 is a valid and reliable questionnaire for the evaluation of headache. However, it cannot differentiate between chronic migraine, episodic migraine, and TTH in Iranian population.

Observational Study
Invasive Techniques for Pain Management in Palliative Care: A Single Center Experience.
To achieve a successful pain control, interventional techniques are required in approximately 15% of the patients admitted to the Palliative Care Service (PCS). ⋯ The analgesic efficacy of these techniques has been adequate in all groups. Patients who required epidural catheters had a higher rate of complications.

Randomized Controlled Trial Multicenter Study Comparative Study
Duloxetine Compared with Pregabalin for Diabetic Peripheral Neuropathic Pain Management in Patients with Suboptimal Pain Response to Gabapentin and Treated with or without Antidepressants: A Post Hoc Analysis.
To examine the efficacy of duloxetine vs. pregabalin in the treatment for diabetic peripheral neuropathic pain (DPNP), comparing patient subgroups with and without concomitant antidepressant use. ⋯ In patients with DPNP inadequately treated with gabapentin without the concomitant use of antidepressants, switching to duloxetine instead of pregabalin may provide better pain reduction. Conversely, in nonresponders to gabapentin who are concomitantly using an antidepressant, switching to duloxetine or pregabalin may provide similar pain reductions.
