While it appears to be beneficial to apply a detailed disease classification system, the costs, cash flow disruptions, and increased investments with physician time incorporated into learning these processes, patient care might unfortunately suffer. This is essentially an unfunded mandate with much of the burden of transitioning to ICD-10 falling on health care providers,especially small independent practices. This will impact interventional pain management practices substantially. ⋯ Thus,very little benefit will be seen by practitioners, which cannot be said for the health care information industry. With overwhelming regulatory atmosphere created by numerous federal regulations and those including under the Affordable Care Act (15), there is no evidence that ICD-10 is needed, there is no evidence that it will be effective, and, finally, there is preponderance of evidence of adverse consequences. Thus, Congress should be cautious in imposing further regulations on already strained independent practices with ongoing regulations and imposing yet another unfunded mandate on the medical profession.

There is converging evidence for the notion that pain affects a broad range of attentional domains. This study investigated the influence of pain on the involuntary capture of attention as indexed by the P3a component in the event-related potential derived from the electroencephalogram. ⋯ These results indicate that voluntary attention serving the maintenance and control of ongoing information processing (reflected by the P3b amplitude) is impaired by pain. In addition, the involuntary capture of attention and orientation to novel, unexpected information (measured by the P3a) is also impaired by pain. Thus, neurophysiological measures examined in this study support the theoretical positions proposing that pain can reduce attentional processing capacity. These findings have potentially important implications at the theoretical level for our understanding of the interplay of pain and cognition, and at the therapeutic level for the clinical treatment of individuals experiencing ongoing pain.

Human experimental pain models are widely used to study drug effects under controlled conditions, but they require further optimization to better reflect clinical pain conditions. To this end, we measured experimentally induced pain in 110 (46 men) healthy volunteers. The quantitative sensory testing (QST) battery (German Research Network on Neuropathic Pain) was applied on untreated ("control") and topical capsaicin-hypersensitized ("test") skin. ⋯ Inclusion in the respective clusters was predictable at a cross-validated accuracy of 86.9% by a classification and regression tree comprising 3 QST parameters (mechanical pain sensitivity, wind-up ratio, and z-transformed thermal sensory limen) from the control sites. Thus, we found that topical capsaicin partly induced the desired clinical pattern of neuropathic pain in a preselectable subgroup of healthy subjects to a degree that fuels expectations that experimental pain models can be optimized toward mimicking clinical pain. The subjects, therefore, qualify for enrollment in analgesic drug studies that use highly selected cohorts to enhance predictivity for clinical analgesia.

Spina bifida is a common birth defect affecting the central nervous system and represents a group of neural tube defects caused by congenital dysraphic malformations of the vertebral column and/or spinal cord. The anatomy in these patients is challenging and includes structural and vascular abnormalities including arteriovenous malformation or fistulae, and fatty substitution of paravertebral tissues. ⋯ Occult spinal dysraphism poses a clinical dilemma for interventional pain specialists managing those patients with lumbar radiculopathy. We report a case of occult spinal dysraphism discovered following the development of post-traumatic radicular symptoms.

Temporomandibular joint syndrome, or Costen syndrome, is a clinically diagnosed disorder whose most common symptoms include joint pain and clicking, difficulty opening the mouth, and temporomandibular joint discomfort. The temporomandibular joint (TMJ) is supplied by the auriculotemporal nerve, a collateral branch of the mandibular nerve (the V3 branch of the trigeminal nerve). ⋯ Patients affected with TMJ syndrome who do not respond to conservative treatments may find a solution in peripheral nerve stimulation, a simple technique with a relatively low level of complications.
