Ketamine is an N-methyl-D-aspartate receptor antagonist that has been in clinical use in the USA for over 30 years. Its ability to provide profound analgesia and amnesia while maintaining spontaneous respiration makes it an ideal medication for procedure-related pain and trauma. In the chronic pain arena, its use continues to evolve. ⋯ Its potential ability to prevent 'windup' and, possibly, 'reboot' aberrant neurologic pathways in neuropathic and central pain states has generated intense interest. However, the long-term use of ketamine for chronic neuropathic pain is limited by its side effect profile, and is largely anecdotal. More research is needed to better ascertain its long-term efficacy and side effects, to determine the ideal candidates for sustained treatment and to develop means of exploiting the antinociceptive properties of ketamine while minimizing the adverse effects.

Chronic pain and substance abuse are common problems. Each entity represents a significant and independent burden to the patients affected by them, the healthcare system caring for them, and society at large supporting them. If the two problems occur together, all of these burdens and their consequences are magnified. ⋯ Clearly, new approaches are required for the most complex of cases. Success is possible only if multiple disciplines provide integrated care that incorporates all of the principles of substance abuse and chronic pain rehabilitation treatment into one package. While experience provides the foundation for implementing these programs, research that documents the methods behind successful outcomes will be needed to sustain support for them.

Chronic opioid therapy for patients with chronic noncancer pain has become controversial, given the rising prevalence of opioid abuse. The prevailing literature suggests that the rate of addiction in chronic noncancer pain patients exposed to opioid therapy is relatively low, especially in those patients without significant concomitant psychiatric disorders and personal and family history of addiction. However, the escalating rate of misuse of prescription opioids has resulted in many clinicians caring for these patients to be more judicious in prescribing opioids. ⋯ Managing the patient with pain and co-occurring opioid abuse is equally challenging. Diagnostic issues, current guidelines for the appropriate use of opioids in the chronic pain population and risk stratification models are examined. Pharmacologic and nonpharmacologic treatment strategies for the patient with pain and opioid addiction are reviewed.

Patients with both chronic pain and substance use disorders offer special challenges and opportunities. They represent a large number of patients with significant costs to themselves and society that translate into poor outcome. The challenges in defining addiction in patients with chronic pain, particularly in those treated with chronic opioid therapy, have distracted the healthcare community from designing effective treatment programs. ⋯ The inadequate treatment of either chronic pain or addiction interferes with the treatment of the other condition and necessitates the design of new treatment paradigms. A new approach to patients with both chronic pain and addiction should start with an evaluation and formulation of these patients to determine the different domains that contribute to their disability (diseases, dimensions, behaviors, life stories). A comprehensive formulation provides the appropriate platform for the implementation of an integrated program of therapy for both conditions that can be intensified to provide more, rather than less, care for the patient that does not meet the goals of functional rehabilitation.

Obesity in our country is a growing concern. There are several different options for weight loss; however, individuals must be self-motivated and amendable to change in order to achieve success with their weight loss goals. Several strategies used by professionals in the US today to treat overweight and obesity, include diet therapy, exercise, behavior modification, pharmacotherapy, and surgery. ⋯ Bariatric surgery is gaining popularity as it has been an effective way to treat obesity. Following gastric bypass surgery, the patients must be prepared to modify their eating behaviors and dietary selections to assist with weight loss and prevent potential complications. Patients should be educated on the dietary guidelines extensively prior to surgery and again post-operatively.
