The choroid is richly innervated by parasympathetic, sympathetic and trigeminal sensory nerve fibers that regulate choroidal blood flow in birds and mammals, and presumably other vertebrate classes as well. The parasympathetic innervation has been shown to vasodilate and increase choroidal blood flow, the sympathetic input has been shown to vasoconstrict and decrease choroidal blood flow, and the sensory input has been shown to both convey pain and thermal information centrally and act locally to vasodilate and increase choroidal blood flow...

Although there is a consensus that the dominant species that make up the adult microbiota remains unchanged in elderly people, it has been reported that there are significant alterations in the proportion and composition of the different taxa, leading to reduced microbiota diversity, as well as an increase of enteropathogens that may lead to chronic inflammation. The ageing of mucosal immune and motor systems also contributes to these changes. As the individual ages, there is a loss in the number of Peyer's patches, an altered local capacity of T and B cell functions as well as chronic macrophage activation...

BACKGROUND: Non-vestibular cranial schwannomas represent a rare type of benign intracranial tumor. Few studies have evaluated the use of stereotactic radiosurgery (SRS) as a primary management option for these lesions. We therefore performed a retrospective review of our institution's experience focussing on efficacy with regards to tumor control and clinical symptom stabilization, as well as treatment safety. METHODS: Patients were included if they underwent at least one SRS procedure for a non-vestibular schwannoma and had at least 6 months of available imaging follow-up...

Capillary malformations (CMs), also known as port-wine stains, are the most common type of congenital vascular malformations. Facial CM often occurs with a quasidermatomal distribution according to the sensory trigeminal nerve distribution. With time, these lesions darken progressively, and soft tissue hypertrophy, bony hypertrophy, and/or nodule formation can develop. Multiple treatments for CM have been reported. However, the mainstay and gold standard therapy for facial or aesthetically sensitive CM is still the pulsed dye laser treatment...

PURPOSE: The clinical neurosensory testing (NST) is currently the reference standard for the diagnosis of traumatic and nontraumatic peripheral trigeminal neuropathies (PTNs) but exhibits both false-positive and false-negative results compared with surgical findings and frequently results in treatment decision delays. We tested the hypothesis that magnetic resonance neurography (MRN) of PTNs can serve as a diagnostic modality by correlating the NST, MRN, and surgical findings. MATERIALS AND METHODS: Sixty patients with traumatic and nontraumatic PTN of varying etiologies and Sunderland classifications underwent NST, followed by MRN using 1...

We examined the distribution of nicotinamide adenine dinucleotide phosphate-diaphorase (NADPH-d)-reactive elements in the central nervous system (CNS) of the common toad, Bufo bufo. The investigation involved adult male and female toads collected during the breeding season. Labeled neurons of different morphological appearances (weakly or darkly stained, unipolar, bipolar, and multipolar) and fibers were observed across all subdivisions of the amphibian brain. Overall, a similar distribution of NADPH-d-labeled neurons was observed in the brain of male and female toads...

Trigeminocardiac reflex is a sudden physiologic response due to mechanical manipulation of any of the branches of trigeminal nerve. Trigeminocardiac reflex occurs due to pressure effect or stretching of trigeminal nerve which causes fall in blood pressure and decrease in heart rate. In this reflex arc, the trigeminal nerve serves as afferent pathway and vagus nerve, which is cardio inhibitory in nature, serves as efferent pathway. Two episodes of trigeminocardiac reflex during maxillofacial trauma surgery is not a common phenomenon...

OBJECTIVE: Microvascular decompression (MVD) is an effective method for directly treating the etiology of trigeminal neuralgia (TGN). This study aims to investigate the factors that predict complete pain relief after MVD for treatment of TGN, and to study efficacy and safety in older patients. METHODS: This study was conducted in patients with TGN that were treated by MVD at Siriraj Hospital during 2004-2015. Cases with secondary TGN were excluded. Data was gathered from medical records, preoperative magnetic resonance imaging (MRI), intraoperative findings, and by telephone in patients lost to follow-up...

Background: Trigeminal neuralgia (TN) is a chronic pain condition characterized by brief episodes of lancinating pain in one or more distributions of the trigeminal nerve. Episodes of pain secondary to TN are triggered by certain stimuli, such as chewing, shaving, or touching the face. Although a common cause of TN is compression of the trigeminal nerve root entry zone by an artery or vein, many cases of TN are idiopathic. However, there have been limited reports in the literature of familial TN...

Peripheral nociceptive stimuli from orofacial structures are largely transmitted by the trigeminal nerve. According to the peripheral noxious stimuli, neurons in the trigeminal ganglion (TG) produce neuropeptides such as substance P, and calcitonin-gene-related peptide, etc. Beside the production of neuropeptides, there exists unique non-synaptic interaction system between maxillary and mandibular neurons in the TG. Neurons in the TG are surrounded by satellite glial cells (SGCs), which initially receive the signal from TG neurons...

REVIEW
Muke Zhou, Ning Chen, Li He, Mi Yang, Cairong Zhu, Fengbo Wu
BACKGROUND: Several anticonvulsant drugs are used in the management of neuropathic pain. Oxcarbazepine is an anticonvulsant drug closely related to carbamazepine. Oxcarbazepine has been reported to be efficacious in the treatment of neuropathic pain, but evidence from randomised controlled trials (RCTs) is conflicting. Oxcarbazepine is reportedly better tolerated than carbamazepine. This is the first update of a review published in 2013. OBJECTIVES: To assess the benefits and harms of oxcarbazepine for different types of neuropathic pain...

Acute administration of chlorogenic acid (CGA) in vitro was recently shown to modulate potassium channel conductance and acid-sensing ion channels (ASICs) in the primary sensory neurons; however, in vivo peripheral effects of CGA on the nociceptive mechanical stimulation of trigeminal neuronal activity remains to be determined. The present study investigated whether local administration of CGA in vivo attenuates mechanical stimulation-induced excitability of trigeminal spinal nucleus caudalis neuronal (SpVc) activity in rats...

OBJECTIVE: A clinical retrospective study was performed to observe the clinical effect of a modified surgical treatment for third-branch primary trigeminal neuralgia. METHOD: Thirty patients who had suffered from neuralgia for several years underwent modified backward avulsion of the inferior alveolar nerve and were followed for 3 to 5 years. In this technique, the inferior alveolar nerve was cut off through the mandibular wisdom tooth extraction socket or the corresponding alveolar ridge window and was avulsed from the mental foramen...

This paper highlighted three advances in the study of the cavernous sinus: 1) the initial formation of the sinus reticulum in early development of the sphenoid bone before ossification 2) extension of reticulum of the sinus and connection with other venules and 3) the cavernous sinus and the nerves evolved inside this sinus during gestation, for example, the trigeminal nerve already formed bundles of motor and parasympathetic components during fetal development. This ontogenetic study further confirmed the cavernous sinus is not a single or a dual set of sinuses, but a group of extensions of venous sinuses or sinusoids...

The authors report the case of a 52-year-old man who presented with rapid-onset lancinating facial pain consistent with trigeminal neuralgia. Magnetic resonance imaging revealed a nonenhancing small lesion on the right trigeminal nerve concerning for an atypical schwannoma or neuroma. The patient underwent resection of the mass via a right retrosigmoid approach. His facial pain completely resolved immediately postoperatively and had not recurred at 6 months after surgery. The mass was consistent with normal brain tissue (neurons and glial cells) without evidence of mitoses...

Coordinated movement of the jaw is essential for catching and swallowing the prey. The majority of the jaw muscles in frogs are supplied by the trigeminal motoneurons. We have previously described that the primary vestibular afferent fibers, conveying information about the movements of the head, established close appositions on the motoneurons of trigeminal nerve providing one of the morphological substrates of monosynaptic sensory modulation of prey-catching behavior in the frog. The aim of our study was to reveal the spatial distribution of vestibular close appositions on the somatodendritic compartments of the functionally different trigeminal motoneurons...

Solitary neurofibromas arising from cranial nerves are rare, and those arising from the peripheral divisions of the trigeminal nerve are even rarer. Although infratemporal fossa (ITF) masses are challenging to remove, certain approaches are considered feasible for this region. The present study reports a rare case of an ITF neurofibroma arising from the inferior alveolar nerve. The 27-year-old male patient presented with numbness of the right jaw. A radiological examination revealed a large mass occupying the ITF, from the mandible to the foramen ovale, originating from the inferior alveolar nerve in the mandible...

Intraoperative monitoring during cerebellopontine angle surgery is widely accepted. While techniques which monitor cranial motor nerves are commonly used, monitoring the sensory afferents has been challenging. Considering the reflex arc, blink reflex (BR) might be useful in monitoring the sensory part of the trigeminal nerve, the brainstem connections and the facial nerve. We describe the case of a patient who developed hemifacial hypoesthesia after microvascular decompression surgery for trigeminal neuralgia...

Preclinical investigations have suggested that altered functioning of brainstem pain modulation circuits may be crucial for the maintenance of some chronic pain conditions. Whilst some human psychophysical studies show that patients with chronic pain display altered pain modulation efficacy, it remains unknown if brainstem pain modulation circuits are altered in individuals with chronic pain. The aim of the present investigation was to determine whether, in humans, chronic pain following nerve injury is associated with altered on-going functioning of the brainstem descending modulation systems...

ABSTRACT:BACKGROUND: Microvascular decompression (MVD) and gamma knife surgery (GKS) are the primary treatments for trigeminal neuralgia (TN). However, many patients require further surgical treatment after the initial surgery for recurrent TN. The objective of this study is to evaluate the efficacy and safety of GKS for recurrent TN cases with prior MVD. METHODS: From October 2008 to June 2015, 658 patients at West China Hospital underwent GKS as the only surgical treatment, and 42 patients underwent GKS with prior MVD...
