Review Case Reports
A retrospective review and treatment paradigm of interventional therapies for patients suffering from intractable thoracic chest wall pain in the oncologic population.
Tumors invading the chest wall and pleura are often incurable, and treatment is targeted toward palliation of symptoms and control of pain. When patients develop tolerance or side effects to systemic opioid therapy, interventional techniques can better optimize a patient's pain. We performed a retrospective review of 146 patients from April 2004 to January 2014 who underwent diagnostic and therapeutic procedures for pain relief. Using four patients as a paradigm for neurolytic approaches to pain relief, we present a therapeutic algorithm for treating patients with intractable thoracic chest wall pain in the oncologic population. ⋯ Intercostal nerve diagnostic blockade with local anesthetic and steroid may lead to prolonged pain relief in this population. Furthermore, depending on tumor location, we have developed a paradigm for the treatment of thoracic chest wall pain in the oncologic population.

Subgroups of patients with chronic low back pain may exhibit differences in self-reported measures of pain, functioning, coping, and psychological distress. The present study compared subgroups of patients with chronic low back pain referred either for pre-spinal cord stimulator (SCS) psychological evaluations or for behavioral pain management (BPM). ⋯ Pre-SCS patients possibly underreport psychological symptoms perhaps to gain SCS approval for SCS. Separate norms and cutoffs for pre-SCS psychological evaluations may be needed to better identify risks of unsuccessful outcomes. Validity scales for measures of psychological distress also could be developed to detect biased reporting. Alternatively, referring clinicians may have referred patients for BPM who were more psychologically distressed and perceived as more in need of psychosocial intervention than those referred for pre-SCS evaluations. Further investigation of clinical referral decisions and assessment bias is warranted to clarify the meaning of these differences and how they apply to patient outcomes.

More than 25% of the US population experiences chronic pain; yet few physicians specialize in the field of pain medicine. This article will review a theoretical model of care that stratifies treatment and patients by level and type of complexity and promotes communication between specialist and primary care providers. ⋯ From the perspective of the busy clinician, the treatment of chronic pain can be overwhelming. The scarcity of trained pain practitioners and the burgeoning number of patients with chronic pain necessitate a new approach that values the complex nature of chronic pain and offers a practical blueprint to meet these challenges.

For interlaminar cervical epidural steroid injections (CESI) the lateral fluoroscopic view (LAT) is often considered to improve needle localization. However, the contralateral-oblique view (CLO) is a useful alternative with potential advantages to improve identification of cervical anatomy and needle depth assessment. The authors explored the attitudes and perceptions of pain medicine fellows currently training in two ACGME-accredited pain medicine fellowship programs regarding the use of these two types of fluoroscopic views. ⋯ For interlaminar CESI, using the CLO is perceived to provide better definition of anatomy and yet is easier to learn. Trainees may become more confident in performing interlaminar CESI with the CLO. We encourage all fellowship programs to include the CLO technique for interlaminar CESI as part of the training.

Randomized Controlled Trial
A randomized, double-blind, crossover study to evaluate the depth response relationship of intradermal capsaicin-induced pain and hyperalgesia in healthy adult volunteers.
The purpose of this study was to evaluate pain and hyperalgesia in response to different depths of intradermal (ID) capsaicin injections in healthy volunteers. ⋯ Injection of capsaicin at different depths in the skin had different effects on heart rate and blood pressure but no effect on pain. These results may have implications on the pharmacology and analgesic predictive value of the model of ID capsaicin.
