Growing evidence suggests that mitochondrial reactive oxygen species (ROS) are involved in various pain states. This study was performed to investigate whether ROS-induced changes in neuronal excitability in trigeminal subnucleus caudalis are related to ROS generation in mitochondria. Confocal scanning laser microscopy was used to measure ROS-induced fluorescence intensity in live rat trigeminal caudalis slices. The ROS level increased during the perfusion of malate, a mitochondrial substrate, after loading of 2',7'-dichlorofluorescin diacetate ($H_2DCF-DA$), an indicator of the intracellular ROS; the ROS level recovered to the control condition after washout. When pre-treated with phenyl N-tert-butylnitrone (PBN) and 4-hydroxy-2,2,6,6-tetramethylpiperidene-1-oxyl (TEMPOL), malate-induced increase of ROS level was suppressed. To identify the direct relation between elevated ROS levels and mitochondria, we applied the malate after double-loading of $H_2DCF-DA$ and chloromethyl-X-rosamine (CMXRos; MitoTracker Red), which is a mitochondria-specific fluorescent probe. As a result, increase of both intracellular ROS and mitochondrial ROS were observed simultaneously. This study demonstrated that elevated ROS in trigeminal subnucleus caudalis neuron can be induced through mitochondrial-ROS pathway, primarily by the leakage of ROS from the mitochondrial electron transport chain.

Trigeminal spinal sensory nucleus is a main relay site in transmission of orofacial pain. Glutamate and aspartate playa role in transmission of primary afferents. This experiment was performed to study the role of capsaicin, KR-25018 and shogaol on the release of glutamate and aspartate from trigeminal spinal sensory nucleus. Release of excitatory amino acids(EAAs) was induced by electrical stimulation of oral mucosa with innocuous or noxious stimuli. Capsaicin($10{\mu}M$), KR-25018($10{\mu}M$), shogaol($10{\mu}M$), ruthenium red and capsazapine were added to perfusion solution to observe the changes in EAA release, and glutamate and aspartate were determined by HPLC. Release of glutamate and aspartate from trigeminal sensory nucleus was increased by noxious stimulation of oral mucosa, but innocuous stimulation did not affect on the release of EAA Capsaicin and KR-25018 increased the release of glutamate and aspartate, and effect of KR-25018 on release of EAA was more potent than capsaicin. But shogaol had a weak effect on release of EAA. Effect of capsaicin and KR-25018 was partially blocked by capsaicin antagonists, ruthenium red and capsazepine.

Background: Neurovascular compression (NVC) is a well-known cause of trigeminal neuralgia (TN). However, patients with idiopathic TN (ITN) do not have evidence of NVC on magnetic resonance imaging (MRI), and other patients may remain asymptomatic despite evidence of NVC on MRI. This suggests that there may be additional risk factors for TN development other than NVC. Although epidemiological factors, such as age and sex differences, are useful for understanding the pathophysiology of TN, detailed statistics for each TN subtype are currently unavailable. Therefore, this study aimed to classify patients with TN into the following groups based on data extracted from past medical records: classical TN (CTN), secondary TN, and ITN. Methods: The characteristics of the groups and their differences were explored. Results: CTN was more common in women than in men, as previously reported, whereas ITN was more common in men than in women. The ratio of pain sites located on the right side of the face was high in all groups. Patients with CTN were also prone to NVC on the asymptomatic side. Conclusion: By investigating TN subtype, it may be possible to elucidate the pathophysiology of TN. This would greatly improve treatment outcomes.

Chronic maxillary sinusitis is a common disease, with symptoms of dull, aching pain or pressure below the eyes and signs such as tenderness over the involved sinus, whereas trigeminal neuralgia is described as severe, paroxysmal, and lancinating brief pain limited in distributions of one or more divisions of trigeminal nerve. In cases where these two non-odontogenic toothache symptoms overlaps, the diagnostic process can be confusing. Here, we report a case of a 54-year-old male patient with chief complaints of intermittent, severe, and electric-like pain in the upper left premolar and first molar area, initially diagnosed with trigeminal neuralgia but finally with maxillary sinusitis after pain recurrence 2 years after that. Therefore, thorough history taking and precise imaging interpretation should be considered to make correct diagnose especially in case of a patient with newly developed or altered or atypical symptoms.

Objectives : This study was conducted to analyze the trends of international clinical research on acupuncture treatment for trigeminal neuralgia. Methods : A total of 14 clinical researches were selected by using PubMed, an international online database, to search for clinical researches written in English and Chinese. Selected papers were analyzed according to study characteristics, study subjects, acupuncture treatment methods, treatment results, evaluation index, safety, and adverse event reports. Results : Acupuncture was mostly used in combination with other treatment methods. The most commonly used acupuncture point was the 'Xiaguan(ST7)', and 11 acupuncture points belonging to the 'Stomach meridian' were used. In most researches, selection of local points and distant points were taken simultaneously, with some researches taking acupuncture points according to trigeminal nerve branch. There were significant improvements in most outcome measures after treatment compared to pre-treatment, and most adverse events disappeared without treatment or decreased or disappeared after grand therapy. Conclusion : According to this study, acupuncture treatment for trigeminal neuralgia was performed in various ways and was found to be effective and safe. However, it is necessary to confirm more meaningful results by supplementing the limitations of existing researches in the future.

A 3 years-old male Tosa dog was referred to Seoul National University Veterinary Medical Teaching Hospital with a history of difficulty in mastication. Clinical signs of dropped jaw, drooling, mild depression and dehydration were observed. According to history taking, physical examination, neurologic examination, complete blood count (CBC), serum chemical profile and radiography, the dog was diagnosed as idiopathic trigeminal nerve paralysis. Electroacupuncture treatment was applied to the dog on local and distal point at an interval of 7 days. Local points were GB-1 (Tong Zi Liao) of gall bladder meridian and ST-7 (Xia Guan) of stomach meridian. Distal points were PC-4 (Xi Men), PC-6 (Nei Guan) of pericardium meridian. Electrical stimulus was performed for 20 minutes at the frequency of 3 Hz, 3 Volts on ST-7. Ten days after the initial electroacupuncture treatment, clinical signs related to trigeminal nerve paralysis were almost disappeared.

A retrospective analysis of 175 patients who were suffering from trigeminal neuralgia was done. We found 21 cases (12.0%) of abnormal findings including brain tumors and cerebrovascular disease on brain MRI. All patients were transferred to department of neurosurgery for operation. Among them, 7 patients refused or gave up operation and received nerve blocks with pure alcohol. Their MRI findings were meningioma, arachnoid cyst, arteriovenous malformation, venous angioma, and frontal sinus cancer This study demonstrates that peripheral nerve block or trigeminal nerve block with pure alcohol would be possible in case of elderly patients, patients who have poor general condition, patients who refuse operation, and brain tumor or cerebrovascular disease which located in dangerous area to be operated.

Trigeminal neuralgia (TN) is generally characterized by lancinating, unilateral, paroxysmal pain occurring in the distribution of the fifth cranial nerve. TN is diagnosed clinically based on the typical patient history, negative findings in a neurologic examination, and the response to medication. Idiopathic TN is the most common type, but TN can result from vascular malformation, compression, trauma, neoplasm, multiple sclerosis, or inflammation. We report a TN case diagnosed as recurrent trigeminal neuritis of the maxillary branch confirmed by magnetic resonance imaging.
