Light microscopy was used to study trigeminal ganglia autopsied from victims of neurosurgical pathology. Quantitative analysis of unchanged, reversibly and irreversibly changed trigeminal ganglion neurocytes was performed in the cases of severe trauma of the brain, its tumors, and aneurysms of cerebral vessels. Quantitative data on neurocyte changes were in each case juxtaposed to clinical features of the course of the disease with due consideration of its etiology. The issues concerning pathogenesis of the disease are discussed in relation to trigeminal ganglion neurocytes' alterations.

Department of Ophthalmology, Harvard Medical School, Schepens Eye Research Institute of Massachusetts Eye and Ear, Boston, MA, USA.
Introduction: Ocular pain is a common complaint to eye care providers, associated with a variety of ocular conditions, among which dry eye disease (DED) is affecting millions of people worldwide. Despite being highly prevalent, ocular pain is not managed adequately in the clinic.
Objectives: The aim of this study was to investigate the analgesic potential of neurokinin-1 receptor (NK1R) antagonism in DED.

Introduction: Conventional management approaches have been challenged in dealing with zoster-related trigeminal neuralgia. Percutaneous trigeminal ganglion stimulation (TGS) has been rarely reported as a potential treatment option for alleviating pain associated with this condition. The present study investigated the application of percutaneous TGS in a series of patients suffering from Zoster-related trigeminal neuralgia to evaluate its potential efficacy of pain relief.

Department of Pain, The Third Xiangya Hospital and Institute of Pain Medicine, Central South University, Changsha, China.
Background: Interventional therapy of trigeminal neuropathic pain has been well documented; however, intraoperative monitoring and management of pain hypersensitivity remains barely reported, which may pose a great challenge for pain physicians as well as anesthesiologists.
Case Presentation: A 77-year-old Han Chinese male, who suffered from severe craniofacial postherpetic neuralgia, underwent pulsed radiofrequency of trigeminal ganglion in the authors' department twice. The authors successfully placed a radiofrequency needle through the foramen ovale during the first procedure with local anesthesia and intravenous sedation (dexmedetomidine).
Designing and clinical application of a 3D-printed personalized model of a radiofrequency needle guide with a maxillary fixator for puncture of the gasserian ganglion for trigeminal neuralgia treatment.

1Department of Neurosurgery, I.M. Sechenov First Moscow State Medical University (Sechenov University), Moscow, Russian Federation.
Objective: The purpose of this study was to present a newly designed 3D-printed personalized model (3D PPM) of a radiofrequency needle guide with a maxillary fixation for gasserian ganglion (GG) puncture.
Methods: Implementation of 3D CT-guided radiofrequency therapy of the GG with and without use of 3D PPM was analyzed. The following parameters were assessed: radiation time, dose area product, air kerma reference point, pain severity during the puncture needle insertion, prosopalgia regression degree (according to visual analog scale) and the severity of facial numbness (according to the Barrow Neurological Institute scale) in the early postoperative period, and postpuncture complications.
Prolactin-induced sensitization of trigeminal nociceptors promotes migraine co-morbidity in endometriosis.
Cephalalgia
January 2025
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.
