Comparative Study
Sensitivities to Thermal and Mechanical Stimuli: Adults with Sickle Cell Disease Compared to Healthy, Pain-free African American Controls.
Evidence supports, but is inconclusive that sensitization contributes to chronic pain in some adults with sickle cell disease (SCD). We determined the prevalence of pain sensitization among adults with SCD pain compared with pain-free healthy adults. In a cross sectional, single session study of 186 African American outpatients with SCD pain (age 18-74 years, 59% female) and 124 healthy age, gender, and race matched control subjects (age 18-69 years, 49% female), we compared responses to standard thermal (Medoc TSA II) and mechanical stimuli (von Frey filaments). ⋯ Findings indicate that persistent allodynia and hyperalgesia can be part of the SCD pain experience and should be considered when selecting therapies for SCD pain. PERSPECTIVE: Compared with matched healthy controls, quantitative sensory testing in adults with pain and sickle cell disease (SCD) demonstrates higher prevalence of sensitization, including central sensitization. The findings of allodynia and hyperalgesia may indicate neuropathic pain and could contribute to a paradigm shift in assessment and treatment of SCD pain.

ReviewThe use of antineuropathic medications for the treatment of chronic pain.
Chronic pain syndromes cost the US healthcare system over $600 billion per year. A subtype of chronic pain is neuropathic pain (NP), which is defined as "pain caused by a lesion or disease of the somatosensory system," according to the International Association for the Study of Pain (IASP). The pathophysiology of neuropathic pain is very complex, and more research needs to be done to find the exact mechanism. ⋯ Many NP patients are misdiagnosed and receive delayed treatment due to a lack of a standardized classification system that allows clinicians to identify, understand, and utilize pain management in these patients. Medications like tricyclic antidepressants, serotonin-norepinephrine reuptake Inhibitor (SNRIs), and gabapentinoids are first-line treatments followed by opioids, cannabinoids, and other drugs. There are limited studies on the treatment of NP.

Clinical Trial
Computed Tomography-Guided Percutaneous Coblation of the Thoracic Nerve Root for Treatment of Postherpetic Neuralgia.
Postherpetic neuralgia (PHN) is one of the most intractable pain disorders and often does not respond to medication, physical, and interventional procedures. Coblation technology has been demonstrated to have potential for neuralgia, but there are rare reports of the efficacy and security of coblation for PHN. The thoracic segment is the most common predilection part of PHN, so we conducted this long-term study to investigate the results of coblation for the treatment of thoracic PHN. ⋯ CT-guided percutaneous thoracic nerve root coblation is an effective and safe method for the treatment of thoracic PHN, and the procedure can also significantly improve the QoL in patients with PHN.
