Background: The trigeminal nucleus caudalis (Vc) is a primary central site for trigeminal transmitting. Noxious stimulation of the trigeminal nociceptors alters the central synaptic releases and neural expression of some inflammatory and trophic agents. Orexin-A and the orexin 1 receptor (OX1R) are expressed in pain pathways including trigeminal pain transmission. However, the the mechanism(s) underling orexin-A effects on trigeminal pain modulation have not been fully clarified. Methods: Trigeminal pain was induced by subcutaneous injection of capsaicin in the upper lip in rats...

Neurotrophic keratitis (NK) is a degenerative corneal disease caused by damage of trigeminal corneal innervation, which leads to spontaneous epithelial breakdown and corneal ulceration. The impairment of corneal sensory innervation causes the reduction of both protective reflexes and trophic neuromodulators that are essential for the vitality, metabolism, and wound healing of ocular surface tissues. A wide range of ocular and systemic conditions, including herpetic keratitis, ocular chemical burns, corneal surgery, diabetes, multiple sclerosis, and neurosurgical procedures, can cause NK by damaging trigeminal innervation...

BACKGROUND: Mid-face Toddler Excoriation Syndrome (MiTES) is a condition recently reported in 3 unrelated children.1 Habitual scratching from the first year of life inflicted deep, chronic, scarring wounds around the nose and eyes. One had mild neurological deficit but there was no other evidence of insensitivity to pain. Bilateral distribution and localisation to the mid-face distinguish MiTES from other causes of self-inflicted skin damage such as trigeminal trophic syndrome. An earlier study of five siblings from a consanguineous Irish family, with lesions corresponding to MiTES plus other sensory deficits, showed homozygous mutations in a gene for hereditary sensory and autonomic neuropathy (HSAN8), PRDM122 ...

Trigeminal trophic syndrome (TTS) is a rare disease process that is thought to occur after insult to the trigeminal nerve. The earliest descriptions of this condition were provided in the early 20th century, yet it remains relatively unknown, with approximately 200 cases since described. Most commonly seen in older women, TTS characteristically involves persistent facial ulceration with loss of sensation and paresthesia along the distribution of the trigeminal dermatome. Ulceration often occurs in the alar region, following self-manipulation in response to paresthesias...

Trigeminal trophic syndrome is a rare condition that develops from trigeminal nerve damage causing dysesthesias that result in self-mutilation. Facial and nasal destruction develops from self-destructive behavior (repetitive picking or scratching) secondary to the altered skin sensation created by the damaged trigeminal nerve. Early recognition of this condition is crucial to the prevention of the detrimental complications of facial ulceration and nasal tissue necrosis that can lead to corneal ulcerations, full-thickness eyelid defect, and canthal lesions...

The trigeminal nerve provides corneal sensitivity and trophic supply to corneal tissues. The impairment of corneal innervation leads to development of neurotrophic keratitis (NK). NK is a rare, degenerative corneal disease characterized by corneal hypo/anesthesia and development of nonhealing corneal epithelial defects and ulcers. NK is a challenging condition with high medical need due to the lack of approved treatments that can restore corneal integrity. Current treatment of NK aims at stimulating corneal healing and preventing disease progression...

BACKGROUND: Trigeminal trophic syndrome (TTS) is an uncommon disorder of the trigeminal nerve tract and trigeminal brainstem nucleus. The syndrome is characterized by a triad of unilateral crescentic ulcers with anesthesia and paresthesias of the involved trigeminal dermatomes. CASE REPORT: A 24-year-old right-handed black female presented to our emergency department with a 4-week history of rapidly progressive painless desquamation/denudation of skin over her right face and scalp...

The cornea has unique features that make it a useful model for regenerative medicine studies. It is an avascular, transparent, densely innervated tissue and any pathological changes can be easily detected by slit lamp examination. Corneal sensitivity is provided by the ophthalmic branch of the trigeminal nerve that elicits protective reflexes such as blinking and tearing and exerts trophic support by releasing neuromediators and growth factors. Corneal nerves are easily evaluated for both function and morphology using standard instruments such as corneal esthesiometer and in vivo confocal microscope...

BACKGROUND: Trigeminal trophic syndrome is a rare complication of peripheral or central damage to the trigeminal nerve characterized by anesthesia, paresthesia and a secondary persistent facial ulceration. METHODS: We describe the case of a 40-year-old woman with previous history of Le Fort I osteotomy for a class III malocclusion who developed trigeminal trophic syndrome. Atypically, the cutaneous symptoms appeared bilaterally and 8 years after surgery. RESULTS: Differential diagnosis was based on clinical history, tissue biopsy and serologic evaluation...

Trigeminal trophic syndrome (TTS) is a condition whereby persistent facial ulceration presents consequent to central or peripheral insult to the trigeminal nerve. Lesions are created by repetitive self-inflicted manipulation and trauma of dysaesthetic skin within the trigeminal dermatome. We discuss four cases with aetiologies varied from presumed microvascular compromise to resection of cerebral meningioma, cerebrovascular accident, and herpes zoster ophthalmicus. We discuss the management of the under-recognised associated periocular skin ulcerations that result from physical manipulation of dysesthic skin and prove to be persistent and challenging to treat...

Complex regional pain syndrome (CRPS) is one of the most challenging chronic pain conditions and is characterized by burning pain, allodynia, hyperalgesia, autonomic changes, trophic changes, edema, and functional loss involving mainly the extremities. Until recently, very few reports have been published concerning CRPS involving the orofacial area. We report on a 50-year-old female patient who presented with unbearable pain in all of her teeth and hypersensitivity of the facial skin. She also reported intractable pain in both extremities accompanied by temperature changes and orofacial pain that increased when the other pains were aggravated...

Vascular endothelial growth factor (VEGF)-B possesses the capacity of promoting injured peripheral nerve regeneration and restore their sensory and trophic functions. However, the contribution and mechanism of VEGF-B in diabetic peripheral neuropathy remains unclear. In the present study, we investigated the expression and role of VEGF-B in diabetic corneal neuropathy by using type 1 diabetic mice and cultured trigeminal ganglion (TG) neurons. Hyperglycemia attenuated the endogenous expression of VEGF-B in regenerated diabetic corneal epithelium, but not that of VEGF receptors in diabetic TG neurons and axons...
