Kratom is an unscheduled opioid receptor agonist that comes in the form of dietary supplements currently being abused by chronic pain patients on prescription opioids. Active alkaloids isolated from kratom such as mitragynine and 7-hydroxymitragynine are thought to act on mu- and delta-opioid receptors as well as alpha-2 adrenergic and 5-HT2A receptors. Animal studies suggest that kratom may be more potent than morphine. ⋯ The goal of this article is to introduce kratom to pain specialists and to spur a conversation on how pain physicians may take the lead to help curb the opioid abuse and overdose epidemic. Further studies may be required to help better understand the clinical and long-term effects of kratom use among chronic pain patients. Key words: Opioid receptor agonist, Kratom, Mitragynine, opioid overdose, chronic pain, substance abuse.

Review Meta Analysis
Incidence of Spontaneous Resorption of Lumbar Disc Herniation: A Meta-Analysis.
Lumbar disc herniation (LDH), a common disease, is often treated conservatively, frequently resulting in spontaneous resorption of the herniated disc. The incidence of this phenomenon, however, remains unknown. ⋯ The phenomenon of LDH reabsorption is well recognized. Because its overall incidence is now 66.66% according to our results, conservative treatment may become the first choice of treatment for LDH. More large-scale, double-blinded, randomized, controlled trials are necessary to study the phenomenon of spontaneous resorption of LDH.Key words: Lumbar, disc herniation, spontaneous resorption, conservative treatment, incidence, country, meta-analysis, systematic review, observational studies, study designs.

Controlled Clinical Trial
Efficacy of Adjuvant 10% Hypertonic Saline in Transforaminal Epidural Steroid Injection: A Retrospective Analysis.
Chronic lower back pain with or without radiculopathy represents an important medical, social, and economic problem. Many treatment modalities and techniques, including surgery and epidural administration of steroids, have been used to manage this pain. Hypertonic saline, which has been used as an adjunct to percutaneous epidural adhesiolysis, can also be injected via a transforaminal approach in expectation of longer-lasting effects. ⋯ Hypertonic saline provides more superior and longer lasting pain relieving effects when added to TFEIs.Key words: Back pain, epidural injections, epidural steroids, hypertonic saline, lumbar, radiculopathy, transforaminal.

Case Reports
A Case Report on Red Ear Syndrome with Tinnitus Successfully Treated with Transcranial Random Noise Stimulation.
The red ear syndrome represents a rare symptom complex consisting of auricular erythema associated with painful and burning sensations. It has been described in combination with tinnitus rarely. It has been hypothesized to be etiologically related to altered trigeminal afferent input, temporomandibular disorders, and thalamic dysfunction. ⋯ This case report demonstrates the feasibility and therapeutic potential of applying neuromodulatory treatment approaches in red ear syndrome, a rare form of trigemino-autonomal headache. Therefore, it deserves detailed observation in clinical routine applications as well as controlled trials further investigating its neurobiological effects. Key words: Red ear syndrome, pain, trigemino-autonomal headache, chronic tinnitus, transcranial electrical stimulation, random noise stimulation.
