Controlled Clinical Trial
Efficacy and Safety of Computed Tomography-Guided Percutaneous Balloon Compression under Local Anesthesia for Recurrent Trigeminal Neuralgia: A Prospective Study.
There are several ways to treat trigeminal neuralgia (TN); however, TN may recur after treatment. This study investigated the efficacy and safety of computed tomography (CT)-guided percutaneous balloon compression (PBC) under local anesthesia for treatment of recurrent trigeminal neuralgia. Patients and Methods. This is a prospective and nonrandomized controlled clinical study. Forty-eight patients with classical TN were scheduled to undergo PBC surgery at the pain department of our institution between January 2021 and June 2021. The patients were prospectively divided into an initial onset group, A (21 cases), and a recurrence group, B (27 cases). All surgeries were performed with CT guidance and under local anesthesia. Postoperative complications were also observed. Pain was assessed using the visual analog scale (VAS) and Barrow Neurological Institute (BNI) scale. Efficacy indices were evaluated at 3, 6, 12, and 18 months after surgery. ⋯ CT-guided PBC under local anesthesia is safe and effective for the treatment of recurrent TN and thus acts as an effective alternative for geriatric patients and those with high-risk factors.

Background: Herpes zoster (HZ) is typically characterized by a burning, stabbing pain, hyperalgesia, and allodynia. In some patients, despite the lesions resolving, the pain persists and becomes chronic. If the pain continues for more than 6 months after the onset of the pain phase, this condition is called postherpetic neuralgia (PHN). ⋯ The medication doses in the early DRG PRF group were significantly lower than those in the other group (p < 0.05). Conclusions: Interventional pain treatment should be applied as soon as possible in the elderly patient group who do not respond to first-line medical treatment or cannot tolerate medical treatment due to its side effects and who have a high risk of developing PHN compared to other age groups. DRG PRF, applied in the early period of medical treatment-resistant acute HZ, is safe and effective, preventing the progression to PHN.

Complex regional pain syndrome (CRPS) represents a rare complication following injury to a limb. The DASH questionnaire (disability of arm, shoulder, and hand) evaluates everyday arm function. We assessed the DASH and its subitems in comparison to patients with brachial plexus lesions or fracture controls, analysed it over time, and in relation to active range of motion (ROM), to determine patients' impairment and trajectory. ⋯ CRPS is as disabling as a complete loss of arm function in brachial plexus lesions and exhibits only partial recovery. Developing QuickDASH versions for CRPS patients could reduce the load of questions in clinical studies. It would be prudent to consider the unexpected age dependency of the DASH in future studies. This trial is registered with DRKS00008964.

Neonatal pain has been underrecognized and undertreated in many settings with the youngest children and neonates suffering the greatest consequences. Despite recent advancements in the assessment and therapy of children's pain, a knowledge-to-practice gap still exists especially in developing nations including our country Ethiopia. ⋯ Health care professionals' knowledge and practice regarding neonatal pain management are insufficient. Multisectoral collaboration is essential to enhance their knowledge and skills and improve the availability of pain scale assessment tools and supportive materials.

Knee osteoarthritis (KOA) pain is caused by nociceptors, which are actually sensory nerve fiber endings that can detect stimuli to produce and transmit pain signals, and high levels of NGF in synovial tissue led to peripheral hyperalgesia in KOA. The purpose of this study is to investigate how sensory nerve fibers respond to the NGF/TrKA signal pathway and mediate the peripheral hyperalgesia in KOA rats. ⋯ This study showed the activation of the NGF/TrKA signaling pathway in KOA promoted the release of pain mediators, increased the innervation of sensory nerve fibers in the synovium, and worsened peripheral hyperalgesia. It also showed increased TRPV1 positive sensory innervation in KOA was mediated by NGF/TrKA signaling and exacerbated peripheral hyperalgesia.
