The current health care system in the United States is structured in a way that ensures that more opportunity and resources flow to the wealthy and socially advantaged. The values intrinsic to the current profit-oriented culture are directly antithetical to the idea of equitable access. A large body of literature points to disparities in pain treatment and pain outcomes among vulnerable groups. ⋯ Specifically, the author argues that the corporatization of pain medicine amplifies disparities in pain outcomes in two ways: 1) directly through driving up the cost of pain care, rendering it inaccessible to the financially vulnerable; and 2) indirectly through an interface with corporate loss-aversion/risk management culture that draws upon irrelevant social characteristics, thus worsening disparities for certain populations. Thus, while financial vulnerability is the core reason for lack of access, it does not fully explain the implications of corporate microculture regarding access. The effect of corporatization on pain medicine must be conceptualized in terms of overt access to facilities, providers, pharmaceuticals, specialty services, and interventions, but also in terms of the indirect or covert effect of corporate culture in shaping clinical interactions and outcomes.

Spinal cord stimulation is the most commonly used implantable neurostimulation modality for management of pain syndromes. For treatment of lower extremity pain, the spinal cord stimulator lead is typically placed in the thoracic epidural space, at the T10-T12 levels. Typically, satisfactory stimulation can be obtained relatively easily. Anatomical variability in the epidural space, such as epidural scarring, has been reported to prevent successful implantation of spinal cord stimulators. Spinal epidural lipomatosis describes an abnormal overgrowth of adipose tissue in the extradural space. Cases have documented spinal epidural lipomatosis complicating intrathecal baclofen pump implantation or causing repeated failure of epidural analgesia. However, so far, there is no published literature describing how spinal epidural lipomatosis affects spinal cord stimulation. ⋯ Spinal epidural lipomatosis significantly increases the impedance in the epidural space, making effective neurostimulation very difficult to obtain. Physicians should consider the possibility of spinal epidural lipomatosis when very high impedances are encountered during lead placement.

Case Reports
Chronic abdominal wall pain and ultrasound-guided abdominal cutaneous nerve infiltration: a case series.
Chronic abdominal wall pain occurs in about 10-30% of patients presenting with chronic abdominal pain. Entrapment of abdominal cutaneous nerves at the lateral border of the rectus abdominis muscle has been attributed as a cause of abdominal wall pain. We report our experience of treating such patients using ultrasound-guided abdominal cutaneous nerve infiltration. ⋯ Ultrasound can reliably be used for infiltration of the abdominal cutaneous nerves. This will improve the safety as well as diagnostic utility of the procedure.

Randomized Controlled Trial
The lack of efficacy of different infusion rates of intrathecal baclofen in complex regional pain syndrome: a randomized, double-blind, crossover study.
Intrathecal baclofen (ITB) is effective in the treatment of dystonia related to complex regional pain syndrome (CRPS). In a previous study, we noted that the responsiveness to ITB declined in 30% of patients once drug delivery was switched from an external to an implanted device associated with a reduction of the infusion rate (IR). ⋯ Increasing the IR at a fixed daily dose is not associated with improvement of dystonia or pain but warrants further investigation in patients in whom side effects prevent further dose escalation.
