Neuropathic pain accounts for 25-50% of pain clinic visits with an estimated prevalence of 4 million. Neuropathic pain is often difficult to diagnose and treat with few pharmacologic options currently available. This review summarizes the latest research on the pathophysiology, diagnosis and treatment of neuropathic pain. ⋯ Neuropathic pain is common, underdiagnosed and undertreated. Diagnosing and understanding the basic mechanisms of neuropathic pain will lead to better treatments of this difficult health care problem.

In today's anesthesia practice, provision of neuraxial anesthesia and analgesia is increasing. Along with the patient's fear of paralysis that accompanies placement of a needle near the spinal cord, any subsequent nerve deficit is usually blamed on the neuraxial block provided. Knowing the side effects from labor, neuraxial anesthesia or both is important as anesthesiologists are the first consultants to evaluate whenever a complication arises in these patients if there is a sensory or motor deficit in the lower extremities. ⋯ Even though the incidence of true neurologic complications arising from neuraxial anesthesia is not known, they appear to be very rare. As anesthesiologists, providing care encompasses knowing the side effects and complications of the anesthetic we provide. Many of the nerve palsies that present in the postpartum patient may be of an obstetric origin, but anesthesiologists should be aware of anesthetic-related complications.

The interscalene brachial plexus block (ISBPB) is a most reliable and commonly performed technique for regional anesthesia of the upper extremity. It has widespread clinical applicability, ranging from use for shoulder surgery as well as diagnostic and therapeutic uses in pain management. Traditional methods described for performing the ISBPB involve identifying surface anatomy landmarks. Unfortunately, in patients with less than ideal landmarks (those with short, thick necks and those lacking adequate muscle tone in the neck area) it becomes increasingly challenging to identify these landmarks. As a result there is greater uncertainty in accurately locating the brachial plexus, and consequently greater risk in performing the block. ⋯ It is concluded that this technique represents a safe, reproducible, and highly successful method for use by anesthesiologists and pain physicians alike.

Low back pain (LBP) is a major physical and socioeconomic entity. A significant percentage of LBP is attributable to internal disc disruption. The management of internal disc disruption has traditionally been limited to either conservative treatment or spinal fusion. ⋯ PNT represents a new less invasive technique for the treatment of discogenic pain, but limited research is available to determine long-term clinical efficacy. IDET and PNT are potentially beneficial treatments for internal disc disruption in carefully selected patients as an alternative to spinal fusion. More basic science and clinical research with long-term follow-up evaluation is necessary.
