Schwannomas (SCs) are benign tumors composed of neoplastic Schwann cells and are relatively uncommon intracranially. Although these tumors are frequently associated with neurofibromatosis type 2 (NF2), they may also arise idiopathically, and their pathogenesis remains poorly understood. A 70-year-old Caucasian man presented with a two-month history of vertigo, gait imbalance, and decreased visual acuity in the left eye accompanied by photophobia, nausea, vomiting, and occasional headaches.

Introduction: We have recently reported the clinical efficacy of mirogabalin for occlusal pain due to post-traumatic trigeminal neuropathic pain (PTTN-occlusal pain) after endodontic treatment according to the International Classification of Orofacial Pain criteria. This study aimed to determine the mirogabalin administration period and timing of dose reduction and suspension for treating this condition based on managing a certain number of cases.
Methods: Patients diagnosed with PTTN-occlusal pain after or during endodontic treatment were included in the study.

Cluster headache is a severe, poorly understood disorder for which there are as yet virtually no rationally derived treatments. Here, Lee Kudrow's 1983 theory, that cluster headache is an overly zealous response to hypoxia, is updated according to current understandings of hypoxia detection, signaling, and sensitization. It is shown that the distinctive clinical characteristics of cluster headache (circadian timing of attacks and circannual patterning of bouts, autonomic symptoms, and agitation), risk factors (cigarette smoking; male gender), triggers (alcohol; nitroglycerin), genetic findings (GWAS studies), anatomical substrate (paraventricular nucleus of the hypothalamus, solitary tract nucleus/NTS, and trigeminal nucleus caudalis), neurochemical features (elevated levels of galectin-3, nitric oxide, tyramine, and tryptamine), and responsiveness to treatments (verapamil, lithium, melatonin, prednisone, oxygen, and histamine desensitization) can all be understood in terms of hypoxic signaling.

Trigeminal neuralgia (TN) is commonly associated with multiple sclerosis (MS). Whether TN should be considered a clinical relapse or evidence of active disease lacks consensus. TN was diagnosed in 0.

Trigeminal neuralgia (TN) is most commonly caused by vascular compression at the trigeminal nerve root entry zone. Secondary TN caused by cranial FD syndrome is extremely rare.
