Drug abuse with illicit drugs and licit drugs has been increasing steadily over the past decade. A recent National Household Survey on Drug Abuse found statistically significant increases between 2000 and 2001 in the use of multiple drugs, including marijuana, cocaine, and non-medical use of pain relievers and tranquilizers. Prescription controlled substance abuse is a major issue in chronic pain management. ⋯ Only one patient tested positive for a combined use of both marijuana and cocaine. This study showed that, in an interventional pain management setting, there is significant use of illicit drugs (16%) with 13% use of marijuana and 3% use of cocaine in patients who are considered as non-abusers of prescription controlled substances and those who are adherent to controlled substance agreements. However, if cocaine is considered as a hardcore drug in contrast to marijuana, abuse of hardcore illicit drugs is only 3%.

Irritation of neural structures, specifically the brachial plexus outside of the cervical spine is capable of producing pain in the upper extremity. These pain patterns may be similar to pain originating from the cervical spine, presenting a diagnostic challenge. Brachial plexus block is performed at multiple levels, including interscalene, supraclavicular, infraclavicular, and axillary. ⋯ Relevant anatomy and proposed technique of brachial plexus block is described. The procedure is performed under fluoroscopy with contrast injection. It is concluded that the proposed technique of brachial plexus block is useful for brachial plexus blockade providing precision and specificity with minimal complications.

This study sought to determine the efficacy of fluoroscopic caudal epidural steroid injections as a conservative treatment in patients with presumably chronic lumbar discogenic pain. ⋯ At greater than two year follow-up, the efficacy of fluoroscopically guided caudal epidural steroid injections in patients with chronic lumbar discogenic pain is poor. Patient satisfaction exceeds the reported rate of efficacy. Patients responding to injection have significantly lower pre-injection pain scores.

It is widely believed that the extent of a patient's subjective complaints are often based on developmental, psychological, social, and cultural factors rather than structural or physical pathology. In patients presenting with chronic low back pain, underlying behavioral problems may not be immediately apparent. These behavioral or non-physiological issues may be secondary to a deliberate deception or may be associated with psychological distress. ⋯ Results showed that 27 patients (22%) presented with non-physiological symptoms, 34 patients (28%) with non-physiological signs, and 19 patients (16%) with combined presence of non-physiological signs and symptoms. Overall there was significant correlation of non-physiological signs with depression, anxiety, and somatization, both by diagnosis of depression, diagnosis of anxiety and elevated scores. However, correlation was present for non-physiological symptoms only with elevated scores of anxiety and somatization.

The purpose of this current opinion on sacroiliac joint pain and dysfunction is to assist interventional pain physicians to apply appropriate treatment decisions and rationale to their patients in pain. Discussion of relevant scientific data and controversial positions will be provided. ⋯ Discussion will provoke support or criticism of the relevant scientific data, and general recommendations for interventional pain management physicians should be considered within the context of the individual practitioners skill and practice patterns. Current Opinion is not intended to provide a standard of care.
