NCT07453511
Trigeminal neuralgia (TN) is a severe type of non-dental orofacial pain that can feel like sudden electric shocks in the face and is often mistaken for tooth pain or other dental problems. This can lead to delays in referral and unnecessary, sometimes irreversible, dental treatment. The goal of this observational study is to evaluate how well a new questionnaire (IDentification of possible Trigeminal Neuralgia - IDTN) identifies adults with possible trigeminal neuralgia among patients attending hospital clinics with orofacial pain, with the aim of supporting its use in dental and general medical practice to improve early recognition and referral. The main questions it aims to answer are: * How accurately does the IDTN questionnaire identify patients with possible trigeminal neuralgia compared with the specialist clinical diagnosis? * Which combination of questionnaire items best supports a practical screening score for use in dental and/or general medical practice? Participants will: 1. Complete the IDTN questionnaire before their clinical appointment (either electronically or on paper) 2. Undergo their usual specialist clinical assessment, during which the final diagnosis will be recorded 3. Allow the research team to compare questionnaire responses with the specialist diagnosis (the reference standard) A subset of participants will also be asked to complete the questionnaire again a few days later to assess test-retest reliability.

This is a prospective, multicenter observational study evaluating the efficacy of ganglion stimulation (medical device) in cases of post-herpetic neuropathy. This study introduces recent methods of phenotypic stratification of postherpetic neuropathy into the field of interventional pain therapy. The aim is to identify which clinical expression of this diverse pathology can derive the greatest benefits from an otherwise effective but expensive therapy such as ganglion stimulation. The study protocol includes the application of a common clinical practice, already in use for several years at the promoting center and participating centers (as well as internationally scientifically codified). It is supported by an innovative stratification of clinical expression (phenotype of the disease), recently introduced in the literature. The study aims to identify, through careful clinical evaluation, predictive indices of the greatest success in invasive ganglion stimulation therapy, a treatment associated with significant system costs and considerable inconvenience for the patient. The results of the experimentation will allow the codification of evaluative clinical pathways to predict a higher success index in certain clinical expressions of postherpetic neuropathy compared to others. This will help reduce the costs of implant trials and enable defining the real objective of the proposed therapy in consultation with the patient.
NCT07370142
Purpose of the Study: This study aims to evaluate the clinical effectiveness and long-term outcomes of "Sphenopalatine Ganglion (SPG) Pulsed Radiofrequency (PRF)" treatment in patients with chronic headaches and facial pain. The SPG is a major neural junction for craniofacial pain signaling. PRF is a safe, minimally invasive technique that modulates pain transmission without causing thermal damage to the nerve tissue. Methodology: The study will include 55 volunteer patients at the Ankara Bilkent City Hospital Algology Clinic who are unresponsive to medical treatments. Patients will undergo the standard "fluoroscopy-guided infrazygomatic approach." Pain intensity (VAS), quality of life, patient satisfaction, and changes in analgesic consumption will be recorded at baseline and during follow-up visits at 1 week, 1 month, 3 months, and 6 months post-procedure using various clinical parameters. Expected Benefits and Risks: The research intends to provide evidence regarding the 6-month long-term impact of this intervention on pain scores and patient well-being. Since the study follows routine clinical practices, it poses no additional risks to participants and aims to optimize future treatment strategies.

NCT06977932
Trigeminal neuralgia (TN), characterized by its refractory nature and recurrence, frequently leads to anxiety, depression, and insomnia, thereby significantly diminishing patients' quality of life and potentially inducing self-harm. Carbamazepine (CBZ) is the first-line medication for TN, yet it presents adverse effects such as addiction and the absence of analgesic effects upon cessation. Acupuncture, particularly electroacupuncture（EA）, has demonstrated efficacy in TN treatment, although its therapeutic outcomes are influenced by various factors. Consequently, this study aims to evaluate the clinical efficacy of EA for TN and its potential as an alternative to CBZ treatment.

NCT07399288
This retrospective observational cohort study uses de-identified electronic health record data from the TriNetX Global Collaborative Network to evaluate whether postherpetic neuralgia after herpes zoster is associated with an increased risk of incident dementia. Adults aged 40 to 120 years with incident herpes zoster between 1 October 2015 and 31 December 2024 are identified using diagnostic codes. Postherpetic neuralgia is defined by International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) codes B02.22 or B02.29 recorded between 90 and 365 days after the index herpes zoster date, and comparators have no such codes within 365 days after index. The primary analysis uses 1:1 propensity score matching and a 365-day landmark design, including only individuals alive and free of dementia at the landmark. Time-to-event analyses estimate hazard ratios for incident dementia and related outcomes.
NCT07367152
This retrospective cohort study will review medical records of patients treated with intercostal nerve radiofrequency for intercostal neuralgia. The goal is to identify patient and clinical factors that are associated with treatment success after the procedure. Outcomes will be assessed using pain measures documented during routine follow-up visits, along with any recorded adverse events. No additional visits, tests, or interventions are required because this study uses previously collected clinical data.

NCT07067892
Postherpetic neuralgia (PHN) is a chronic pain syndrome that can be resistant to treatment, leading to physical and social disability, psychological disturbances, and potentially persisting for years . The varicella-zoster virus remains latent in the sensory neurons of individuals who have previously contracted varicella (chickenpox). Reactivation of the latent virus results in herpes zoster (HZ). In most patients, HZ initially presents with dermatomal pain, and within a few days, characteristic dermatomal vesicular eruptions typically develop. These skin lesions usually heal within 2-4 weeks; however, pain may persist even after the resolution of the rash . The pathogenesis of PHN involves increased sensitization of central neurons, decreased function of inhibitory neuronal pathways, inflammation and nerve injury within the peripheral nervous system, and abnormal signal transmission following such damage. PHN represents the most common complication of HZ. It occurs in approximately 9-19% of all patients with HZ. The incidence of PHN increases with advancing age: it affects approximately 2% of individuals younger than 50 years, about 20% of those older than 50 years, and nearly 35% of those older than 80 years . Various treatment modalities, including pharmacologic agents and interventional procedures, are available for the management of PHN-related pain. This study primarily aims to evaluate the change in pain in PHN patients who underwent SPSIPB using the NRS-11. The secondary aim was to evaluate the effect of SPSIPB on neuropathic pain characteristics using the DN-4 scale and to investigate its effects on patients' quality of life using SF-12 scale.

NCT07238244
The goal of this observational study is to develop and validate a machine learning-based model for predicting pain recurrence risk after percutaneous balloon compression (PBC) in adult patients with primary trigeminal neuralgia (TN) who had their first PBC treatment. The main questions it aims to answer are: Can the machine learning-based model accurately predict pain recurrence after PBC in these primary TN patients? What key factors (like patient baseline traits, imaging parameters, surgical operation data) affect PBC post-operative pain recurrence? Do machine learning algorithms perform better than traditional Cox proportional hazards regression in predicting such recurrence? Participants (with existing PBC treatment records) will have their past data-including clinical info from the hospital's electronic medical record system, imaging data from the image archiving system, surgical data from the surgical anesthesia system, and follow-up data from the outpatient system-collected and analyzed to build and validate the prediction model.

NCT06290661
The goal of this clinical trial is to evaluate safety and efficacy of percutaneous peripheral nerve stimulation in patients with peripheral neuropathic pain. The main questions it aims to answer are: 1. The efficacy of percutaneous peripheral nerve stimulation in patients with peripheral neuropathic pain 2. The safety of percutaneous peripheral nerve stimulation in patients with peripheral neuropathic pain Participants are going to undergo procedure that implant peripheral nerve stimulation electrode produced by Jiangsu CED Medtech Co., Ltd. Then the subjects, whose VAS scores decrease more 30% than baseline level, are classified into two groups randomly. One of the group receiving active stimulation called trial group and another receiving placebo stimulation called control group. All subjects are required to make their own subjects' pain diary to record VSA score before and after implantation until at the end of follow-up. Also, participants are asked to report use of analgesic medications, number of awakenings and adverse events. Researchers will compare pain scores between the two groups to see if peripheral nerve stimulation is effective to patients with peripheral neuropathic pain.

Chronic pain affects 1 in 4 US adults, and many cases are resistant to almost any treatment. Deep brain stimulation (DBS) holds promise as a new option for patients suffering from treatment-resistant chronic pain, but traditional approaches target only brain regions involved in one aspect of the pain experience and provide continuous 24/7 brain stimulation which may lose effect over time. By developing new technology that targets multiple, complimentary brain regions in an adaptive fashion, the investigators will test a new therapy for chronic pain that has potential for better, more enduring analgesia.
