Chronic pain, especially low back pain and hip pain, has been a growing public health concern that affects over 100 million Americans annually. Radiofrequency ablation (RFA) has distinct advantages over other chronic pain management modalities and its use has been increasing over the past decade. Among the growing population with comorbid conduction disorders and persistent pain, RFA and its potential interference with implantable cardiac devices is of concern.RFA is becoming a foundational element of persistent pain management and has been shown to be effective in a multitude of chronic pain syndromes. Cardiac implantable electronic devices (CIED), such as cardiac pacemakers or implantable cardioverter defibrillators, have been used in the treatment of cardiac conduction diseases for a number of decades. With our aging population, these diseases have increased in both incidence and prevalence. Chronic pain and cardiac conduction diseases are both common in our increasingly aging population. ⋯ This study provides evidence that bipolar RFA can be safely used in patients with CIEDs for chronic pain provided that proper precautions are employed. Considerations for safe use are provided.

Diagnostic injections (blocks) are a valuable tool in the management of chronic noncancer pain. By precise blockade of specific neural structures and observation of pain responses, pain mechanisms can be accurately defined. With such information, therapeutic procedures targeting neural structures are possible. Fibromyalgia is a disorder of pain processing with characteristic symptoms. The 2010 American College of Rheumatologists fibromyalgia diagnostic criteria evaluates these symptoms in a scoring system, allowing more objectivity in the diagnosis. We hypothesize that patients with fibromyalgia phenotype fulfilling the 2010 American College of Rheumatologists criteria may respond to diagnostic blocks differently when compared to patients without fibromyalgia phenotype. ⋯ We conclude that after physician selection, the presence of fibromyalgia phenotype does not influence the outcome from diagnostic block. It is likely therefore that fibromyalgia phenotype should not influence the decision to perform diagnostic blocks if indicated based on assessment by an experienced pain physician.

Randomized Controlled Trial
Efficacy and Safety of Radiofrequency Thermocoagulation with Different Puncture Methods for Treatment of V1 Trigeminal Neuralgia: A Prospective Study.
Radiofrequency thermocoagulation through the supraorbital foramen with a different puncture method is a new approach for the treatment of ophthalmic division trigeminal neuralgia. ⋯ The transverse puncture method during radiofrequency thermocoagulation through the supraorbital foramen had better efficacy and fewer complications in comparison with the vertical puncture method when treating ophthalmic division trigeminal neuralgia.
