Observational Study
Use of High-Concentration Capsaicin Patch for the Treatment of Pelvic Pain: Observational Study of 60 Inpatients.
Chronic pelvic, perineal and gluteal neuralgia is often experienced in a similar way to neuropathic pain, in the territories of four nerves: ilio-inguinal, pudendal, inferior cluneal and posterior gluteal nerves. These pains are often refractory to medical treatment based on the use of systemic molecules with disabling adverse effects and surgical procedure may be necessary. ⋯ These results suggest the value of high-concentration capsaicin 8% patch in the treatment strategy for patients with chronic pelvic, perineal and gluteal neuralgia. This treatment would be particularly indicated in the management of coccygodynia.Key words: Pelvic pain, neuropathic pain, pudendal nerve, ilio-inguinal nerve, inferior cluneal nerve, posterior gluteal nerve, capsaicin, capsaicin patch, coccygodynia.

Use/misuse of the opioid combination hydrocodone-acetaminophen has been associated with permanent hearing loss. Although reports have been rare, this potential effect can have significant detrimental effect on patients' overall quality of life. To date, the ototoxic effect of hydrocodone alone has not been systematically investigated. ⋯ No ototoxic signal was observed for single-entity hydrocodone tablets at the dosages and treatment durations investigated. Key words: Audiologic monitoring, clinical trials, hydrocodone, opioids, ototoxicity monitoring, sensorineural hearing loss.

Case Reports
High Frequency Spinal Cord Stimulation for Complex Regional Pain Syndrome: A Case Report.
Complex regional pain syndrome (CRPS) is a chronic, debilitating, neuropathic pain condition which is often misdiagnosed, difficult to manage, and lacks proven methods for remission. Most available methods provide some relief to a small percentage of patients. Recent FDA approval and superiority of the Nevro Senza 10-kHz high frequency (HF10) spinal cord stimulation (SCS) therapy over traditional low-frequency spinal cord stimulation for treatment of chronic back and leg pain may provide a new interventional therapeutic option for patients suffering from CRPS. ⋯ Implantation of the HF10 device provided over 75% relief of pain, erythema, heat, swelling, and tissue necrosis to the entire region within 1 month of treatment. Because the HP10 therapy provides pain relief without paresthesia typical of traditional low-frequency, this system may provide relief for patients suffering from chronic pain. Key words: Complex regional pain syndrome, spinal cord stimulation, Nevro Senza HF10, erythema, knee, thigh.

Symptomatic headaches attributed to unruptured brain arteriovenous malformations (ubAVMs) are very common and affect patients' quality life, but multidisciplinary care of ubAVMs to improve symptomatic headache remains unclear. ⋯ Occipital ubAVM is more likely to present with migraine-like headache, while frontotemporal ubAVM tends to present with tension-type-like headache. The effectiveness of multidisciplinary care for ubAVM to improve headache has been shown, but the natural history of ubAVM patients with headache remains unclear.Key Words: Unruptured brain arteriovenous malformations, headache, headache improvement, natural history.

Clinical Trial
Vitamin D Supplementation in Patients with Chronic Low Back Pain: An Open Label, Single Arm Clinical Trial.
Vitamin-D deficiency may possibly be related to chronic low back pain (CLBP). ⋯ Vitamin-D supplementation in deficient CLBP patients may lead to improvement in pain intensity and functional ability apart from normalization of the levels. Future controlled clinical trials are required to confirm the hypothesis.Key words: Vitamin D, deficiency, screening, low back pain, chronic, supplementation.
