Intracranial neurostimulation for pain relief is most frequently delivered by stimulating the motor cortex, the sensory thalamus, or the periaqueductal and periventricular gray matter. The stimulation of these sites through MCS (motor cortex stimulation) and DBS (deep brain stimulation) has proven effective for treating a number of neuropathic and nociceptive pain states that are not responsive or amenable to other therapies or types of neurostimulation. Prospective randomized clinical trials to confirm the efficacy of these intracranial therapies have not been published. ⋯ DBS may be employed for a number of nociceptive and neuropathic pain states, including cluster headaches, chronic low back pain, failed back surgery syndrome, peripheral neuropathic pain, facial deafferentation pain, and pain that is secondary to brachial plexus avulsion. The unique lack of stimulation-induced perceptual experience with MCS makes MCS uniquely suited for blinded studies of its effectiveness. This article will review the scientific rationale, indications, surgical techniques, and outcomes of intracranial neuromodulation procedures for the treatment of chronic pain.

The health care industry in general and care of chronic pain in particular are described as recession-proof. However, a perfect storm with a confluence of many factors and events -none of which alone is particularly devastating - is brewing and may create a catastrophic force, even in a small specialty such as interventional pain management. Multiple challenges related to interventional pain management in the current decade will include individual and group physicians, office practices, ambulatory surgery centers (ASCs), and hospital outpatient departments (HOPD). ⋯ There is focus on avoiding waste, abuse, fraud, and also cutting costs. Evidence-based medicine (EBM) and comparative effectiveness research (CER) have been introduced as cost-cutting and rationing measures, however, with biased approaches. This manuscript will analyze various issues related to interventional pain management with a critical analysis of physician payments, office facility payments, and ASC payments by various payor groups.

Importance of urine drug testing in the treatment of chronic noncancer pain: implications of recent medicare policy changes in kentucky.
Urine drug testing has become a widely used tool in American society for deterring illicit drug use. In the practice of medicine, urine drug testing is commonly used to help diagnose substance misuse, abuse, or addiction. ⋯ Regular urine drug testing should be a part of acute and chronic pain management whether or not the patient has any signs or symptoms of drug misuse.

Nucleoplasty is a minimally invasive procedure for treating pain caused by symptomatic disc herniation that is refractory to conservative therapy. Observational studies have reported differing outcomes for this procedure and thus its effectiveness is yet to be determined. ⋯ Observational studies suggest that nucleoplasty is a potentially effective minimally invasive treatment for patients with symptomatic disc herniations who are refractory to conservative therapy. The recommendation is a level 1C, strongly supporting the therapeutic efficacy of this procedure. However, prospective randomized controlled trials with higher quality of evidence are necessary to confirm efficacy and risks, and to determine ideal patient selection for this procedure.
