Filter by:This is a 16-week non-blinded, parallel, controlled trial to determine the feasibility and potential efficacy of an olive oil dietary intervention to alleviate facial pain caused by trigeminal neuralgia type 1 (TGN).
Interventional therapies for Trigeminal Neuralgia are of variable efficacy and safety, and have different results for different periods of time before the recurrence of symptoms. Interventional therapy for TN is either destructive with trigeminal nerve sensory function destroyed intentionally or non-destructive with decompression of the trigeminal nerve and preservation of its regular function. The most common procedures in treating TN pain are the use of radiofrequency (RF). the aim of this study is to assess the possible value of motor index as a prediction of success of radiofrequency lesioning of the Gasserian ganglion during treatment of trigeminal neuralgia.
Trigeminal neuralgia (TN) is characterized by sudden, severe, usually unilateral, transient, stinging, recurrent electrocute-like shock in one or more divisions of the trigeminal nerve, lasting from a few seconds to less than 2 minutes.Simple daily-life activities, such as washing the face, brushing the teeth, eating, and talking, or the slight touch of trigger points may trigger the attack of pain of TN, resulting in a decline in the patient's quality of life (QoL). Trigger zones predominantly locate in the perioral and nasal region. Paroxysmal pain is associated with triggers in virtually all patients with TN. TN may be caused by abnormality of the trigger zone and the blockade of Na+ channel of trigger zone may be a novel and effective treatment methods for TN. Currently, most patients with TN may not achieve adequate pain relief with a single therapeutic agent. Multiple analgesics targeting different mechanisms of the pain pathway are often used.5% lidocaine medicated plaster (LMP) is a white hydrogel plaster containing adhesive material. LMP was approved for post-herpetic neuralgia (PHN) treatment by the United States Food and Drug Administration (FDA) in 1999. Tamburin et al reported that 2 patients with primary TN who stopped oral drugs because of side effects or refused surgical procedures. Both patients were instructed to wear LMP over the affected area and LMP resulted in reduction of pain intensity and the number of pain paroxysms without side effects. However, due to limitations of these open-label design studies, the observed reductions in pain intensity may have been due to treatment effect, placebo effect, changes in underlying disease state, or a combination of these factors. Therefore, randomized controlled trials will be need to be performed to draw about the efficacy of the LMP in TN. The PATCH trial is a prospective, double-blinded, vehicle-controlled, parallel-group, multicenter, enriched enrolment with randomized withdrawal (EERW) trial aimed at estimating the efficacy and safety of LMP in patients with TN. After providing informed consent and completing a baseline evaluation, patients will participate in an initial open-label treatment period of LMP (active patches). This openly titrated process is close to clinical practice and can provide data on the proportion of responders and non-responders, the optimal dose of the analgesic drug, and the proportion of withdrawal due to adverse effects. A responder at the end of the open-label treatment phase will be included in the subsequently double-blind treatment phase.
The aim of this study is to investigate the efficacy of greater occipital nerve block and cervical injections with lidocaine
The study is a non-interventional prospective observational study in patients with trigeminal neuralgia that undergoes micovascular decompression. The aim is to evaluate the efficacy and complications 2 years after microvascular decompression
Clinical characteristics, neuroanatomical findings and efficacy of medical and surgical treatment of symptomatic trigeminal neuralgia - a systematic prospective study of 60 consecutive patients
The current study investigated the efficacy of pulsed radiofrequency in pain reduction in TN patients and compared the efficacy and the impact on the quality of life of the standard technique with a prolonged duration technique and a higher voltage one. Entire enrolled patients were diagnosed as classic TN according to the international headache society classification (IHS, 2013) and underwent brain MRI and MRA to exclude secondary causes. Patients were randomly divided into three groups, Group A patients underwent PRF using the standard settings, group B patients underwent PRF with prolonged duration and Group C patients underwent PRF with higher voltage. VAS and pain amplitude reduction were recorded before the intervention and 1 hour, 1 day, 1week, 1 month, 6 months and 1year after it. Quality of life was assessed before and 1 year after the intervention.
The investigators will treat patients (targeting enrollment of n=20) who suffer from trigeminal or glossopharyngeal nerve pain in the context of painful small fiber neuropathy. The primary pain-related objective is reduction of pain and reduced use of rescue and other anti-pain medications. Another goal is to monitor and confirm the safety profile established in the migraine population, during previous Phase 3 trials.
Clinical randomized study to compare the clinical effectiveness between two modalities of treatment of trigeminal neuralgia namely gamma knife radio surgery and microvascular decompression
A phenome-wide association study (PheWAS) identified an association between a loss of function variant in the human alpha 2B adrenergic receptor gene and trigeminal nerve disorders. Guanfacine is the oldest alpha-2 adrenergic agonist in clinical use and is approved for hypertension and attention deficit hyperactivity disorder. We hypothesize that guanfacine will be an effective adjunct to lidocaine for the treatment of neuropathic pain by enhancing and prolonging pain relief due to its activation of alpha-2 adrenergic receptors. The objectives of the study will be to evaluate the efficacy and safety of guanfacine in combination with lidocaine for trigeminal nerve block procedures for pain management in trigeminal neuralgia patients. This study will evaluate the efficacy of guanfacine in reducing acute pain and extending duration of pain relief when delivered in combination with lidocaine as a trigeminal nerve block, measured by Visual Analog Scale (VAS) data collected at specific time points after each injection.
