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.

Observational Study
Anatomical Variants of the Pudendal Nerve Observed during a Transgluteal Surgical Approach in a Population of Patients with Pudendal Neuralgia.
Several studies have described the course and anatomical relations of the pudendal nerve. Several surgical nerve decompression techniques have been described, but only the transgluteal approach has been validated by a prospective randomized clinical trial. The purpose of this study was to describe the course of the nerve and its variants in a population of patients with pudendal neuralgia in order to guide the surgeon in the choice of surgical approach for pudendal nerve decompression. ⋯ This is the first study to describe the surgical anatomy of the pudendal nerve in a population of patients with pudendal neuralgia. In more than 70% of cases, pudendal nerve entrapment was situated in the space between the sacrospinous ligament and the sacrotuberous ligament. Anatomical variants of the pudendal nerve were also observed in 13% of patients, sometimes with a transligamentous course of the nerve. In the light of these results, we believe that a transgluteal approach is the most suitable surgical approach for safe pudendal nerve decompression by allowing constant visual control of the nerve.Key words: Surgical, operative technique, pudendal, neuralgia, transgluteal approach.

Observational Study
Occipital Nerve Stimulation for Refractory Chronic Migraine: Results of a Long-Term Prospective Study.
Refractory chronic migraine affects approximately 4% of the population worldwide and results in severe pain, lifestyle limitations, and decreased quality of life. Occipital nerve stimulation (ONS) refers to the electric stimulation of the distal branches of greater and lesser occipital nerves; the surgical technique has previously been described and has demonstrated efficacy in the treatment of a wide variety of headache disorders. ⋯ We consider that the trigemino-cervical autonomous and cervical connection may explain why ONS might relieve chronic migraine pain, but this is just a theoretical explanation which should be demonstrated in future studies. The results achieved in this study suggest that ONS may provide long-term benefits for patients with medically intractable chronic migraine. These outcomes are slightly better than previous reports and were maintained over the 7-year follow-up. We believe that an accurate selection of patients, realization of diagnostic occipital nerve blocks, psychological evaluations, rigorous surgical technique, and appropriate parameter programming helped us achieve these outcomes. Key words: Refractory chronic migraine, headache, occipital nerve stimulatino, peripheral nerve stimulation, occipital nerve block.

Failed back surgery syndrome (FBSS) is a frequently encountered disease entity following lumbar spinal surgery. Although many plausible reasons have been investigated, the exact pathophysiology remains unknown. Various medications, reoperations, interventions such as spinal cord stimulation, epidural adhesiolysis or epidural injection, exercise therapy, and psychotherapy have been suggested treatment options. However, the evidence of the clinical outcome for each treatment has not been clearly determined. ⋯ Epidural adhesiolysis or spinal cord stimulation can be effective in order to control chronic back pain or leg pain due to FBSS, and its recommendation grades are A and B, respectively. Other treatments showed poor or inconclusive evidence.Key words: Failed back surgery syndrome, post spinal surgery syndrome, chronic low back pain, post lumbar surgery syndrome, epidural adhesiolysis, spinal cord stimulation, epidural injection, revision.
