Purpose: To further evaluate the effects of gasserian ganglion block treatment with local anesthetics and steroids on patients with acute/subacute zoster-related trigeminal neuralgia.
Patients And Methods: This is a multicenteric retrospective study which included patients between the ages of 26-92 years, who suffered from acute/subacute zoster-related trigeminal neuralgia and had undergone CT-guided gasserian ganglion block. The medical records of these patients between January 13, 2016 and August 25, 2021 were retrieved, and the patients were followed up for 6 months. Follow-up outcomes were Numerical Rating Scale (NRS) scores, medications and dosage. The effective rate was defined as the number of cases with NRS score reduction of >50%/total number of cases×100% at 12 weeks postoperatively.
Results: The postoperative NRS scores were significantly decreased in all patients (P < 0.05), and NRS scores in acute zoster group were lower than those in subacute zoster group at different time points (P < 0.05). The percentage of patients who had a reduction of medication use value of >50% was 56.4% and the effective rate was 66.7% in all patients, at 3 months after the block treatment. There was no significant difference in the reduction of medication use value of >50% and the effective rates between the two groups. There were no intracranial hemorrhage, infection or other serious adverse effects in either groups.
Conclusion: CT-guided gasserian ganglion block with local anesthetics and steroids can be an effective and safe technique to relieve the pain of acute/subacute zoster-related trigeminal neuralgia.

Prolactin-induced sensitization of trigeminal nociceptors promotes migraine co-morbidity in endometriosis.

Department of Pharmacology, University of Arizona College of Medicine, Tucson, AZ, USA.
Background: Women with endometriosis are more likely to have migraine. The mechanisms underlying this co-morbidity are unknown. Prolactin, a neurohormone secreted and released into circulation from the anterior pituitary, can sensitize sensory neurons from female, but not male, rodents, monkeys and human donors.

Objective: The neuropeptide calcitonin gene-related peptide (CGRP) has been established to be a key signaling molecule in migraine, but little is known about the differences between the two isoforms: αCGRP and βCGRP. Previous studies have been hampered by their close similarity, making the development of specific antibodies nearly impossible. In this study we sought to test the hypothesis that αCGRP and βCGRP localize differently within the neurons of the mouse trigeminal ganglion (TG), using αCGRP knock out (KO) animals.

Background: Bilateral trigeminal neuralgia secondary to multiple sclerosis is an extremely rare condition. When Gasserian ganglion block is performed, it is necessary to achieve reliable long-term analgesic effects while avoiding treatment-related complications.
Case Presentation: A 49-year-old male with multiple sclerosis exhibited persistent dull pain and paroxysmal electric shock-like pain in his bilateral maxillary molars and mandible.

Background There are many reports of anatomical and physiological studies on trigeminal ganglion neurons, but few studies have analyzed temporal changes in the excitation of the trigeminal ganglion. This study aimed to establish an experimental system for spatial and temporal imaging analysis of the excitatory dynamics of trigeminal ganglion cells evoked by stimulation of a peripheral branch of the trigeminal nerve. Methods After excision of the trigeminal ganglion with the inferior alveolar nerve (IAN) from Sprague Dawley rats (seven to nine weeks old), 400-µm-thick slices of the trigeminal ganglion with the IAN were prepared.

While the impact of (-)-epigallocatechin-3-gallate (EGCG) on modulating nociceptive secondary neuron activity has been documented, it is still unknown how EGCG affects the excitability of nociceptive primary neurons in vivo. The objective of the current study was to investigate whether administering EGCG locally in rats reduces the excitability of nociceptive primary trigeminal ganglion (TG) neurons in response to mechanical stimulation in vivo. In anesthetized rats, TG neuronal extracellular single unit recordings were made in response to both non-noxious and noxious mechanical stimuli.
