Olfactory Ensheathing Cells Alleviate Facial Pain in Rats with Trigeminal Neuralgia by Inhibiting the Expression of P2X7 Receptor.

Brain Sci 2022 May 30;12(6). Epub 2022 May 30.

Department of Anatomy, Basic Medical School, Nanchang University, Nanchang 330006, China.

Trigeminal neuralgia (TN) is a common facial neuropathic pain that is mainly characterized by spontaneous or induced needling or electric shock pain in the innervation area of the trigeminal nerve. It is also referred to as "the cancer that never dies". The olfactory ensheathing cell (OEC) is a special glial cell in the nervous system that has a strong supportive function in nerve regeneration.

Recombinant Human Nerve Growth Factor for Pediatric Neurotrophic Keratopathy.

Eye Contact Lens 2022 Jul 3;48(7):303-305. Epub 2022 Jun 3.

Department of Ophthalmology (D.N., S.S.M.F.), University of California Los Angeles, Los Angeles, CA; and Department of Ophthalmology (D.N.), Banphaeo General Hospital, Samut Sakhon, Thailand.

Abstract: A 4-year-old boy presented with right neurotrophic corneal ulcer, lagophthalmos, and facial palsy 8 months after neurosurgery for synchronous brain tumors. Initial treatment with topical antibiotics, topical corticosteroids, lubrication, and lateral tarsorrhaphy successfully treated the corneal epithelial defect; however, the cornea continued to demonstrate diffuse epitheliopathy and a dense stromal opacity and remained insensate on Cochet-Bonnet esthesiometry. After a course of topical cenegermin, central corneal sensation normalized, and the corneal epitheliopathy was markedly improved. Read More

Ophthalmic Plast Reconstr Surg 2022 May 20. Epub 2022 May 20.

Department of Ophthalmology, University of Colorado School of Medicine, Aurora, Colorado.

The purpose of this report is to discuss high-pressure injection injuries involving the face and orbit and discuss factors affecting prognosis and management as these injuries are rare and uniquely challenging to manage given the complex anatomy and extensive damage that may occur. In this case, we present severe injury to the left orbit, maxillofacial region, and neck of a 29-year-old male who suffered a high-pressure diesel injection injury requiring several surgical debridements, intensive care unit (ICU) level care, and ultimately sub-total exenteration. Initial management involved systemic antibiotics, steroids, and surgical debridement; however, our patient experienced subsequent rapid deterioration resulting in admission for more aggressive subspecialty intervention.

The Molecular Basis and Pathophysiology of Trigeminal Neuralgia.

Int J Mol Sci 2022 Mar 25;23(7). Epub 2022 Mar 25.

Department of Anesthesiology, Perioperative and Pain Medicine, Stanford University School of Medicine, Stanford, CA 94305, USA.

Trigeminal neuralgia (TN) is a complex orofacial pain syndrome characterized by the paroxysmal onset of pain attacks in the trigeminal distribution. The underlying mechanism for this debilitating condition is still not clearly understood. Decades of basic and clinical evidence support the demyelination hypothesis, where demyelination along the trigeminal afferent pathway is a major driver for TN pathogenesis and pathophysiology.

[Technique of Microvascular Decompression for Hemifacial Spasm Based on Surgical Anatomy].

No Shinkei Geka 2022 Mar;50(2):467-479

Department of Neurosurgery, Saitama Medical University Hospital.

This article describes the anatomical approach and operative points of microvascular decompression for hemifacial spasm based on the author's personal experience with 1,000 cases. As vascular compression of the facial nerve is often quite caudal, it is necessary to ensure that the compressing arteries in this area are moved. Neither the vessels nor the prosthesis used to move them should not touch the root exit zone of the nerve(vascular transposition nerve isolation technique). Read More
