Increased expression of Netrin-4 is associated with allodynia in a trigeminal neuropathic pain model rats by infraorbital nerve injury.

PLoS One 2021 29;16(4):e0251013. Epub 2021 Apr 29.

Department of Molecular Neuroscience, Osaka University Graduate School of Medicine, Suita, Osaka, Japan.

Neuropathic pain refers to pain caused by lesions or diseases of the somatosensory nervous system that is characteristically different from nociceptive pain. Moreover, neuropathic pain occurs in the maxillofacial region due to various factors and is treated using tricyclic antidepressants and nerve block therapy; however, some cases do not fully recover. Netrin is a secreted protein crucially involved in neural circuit formation during development, including cell migration, cell death, neurite formation, and synapse formation. Read More

Computed Tomography Analysis of the Feline Infraorbital Foramen and Canal.

Front Vet Sci 2020 27;7:619248. Epub 2021 Jan 27.

College of Veterinary Medicine and Biomedical Sciences, Colorado State University, Fort Collins, CO, United States.

Feline skull anatomic variation is plain to see with casual observation. Obtaining an in-depth understanding of this anatomic variability is critical to performing safe and effective regional anesthesia for dental procedures and maxillofacial surgeries. Maxillofacial anatomic variability is proven to impact the placement and efficacy of nerve blocks in dogs and horses, but similar studies have not been performed in cats. Read More

Craniofacial neuralgias.

NeuroRehabilitation 2020 ;47(3):299-314

Physical Medicine and Rehabilitation, Indiana University School of Medicine, Rehabilitation Hospital of Indiana, 4141 Shore Drive, Indianapolis, IN, USA.

While non-headache, non-oral craniofacial neuralgia is relatively rare in incidence and prevalence, it can result in debilitating pain. Understanding the relevant anatomy of peripheral branches of nerves, natural history, clinical presentation, and management strategies will help the clinician better diagnose and treat craniofacial neuralgias. This article will review the nerves responsible for neuropathic pain in periorbital, periauricular, and occipital regions, distinct from idiopathic trigeminal neuralgia. Read More

Department of Chemical and Biomolecular Engineering, Hong Kong University of Science and Technology, Hong Kong, Hong Kong.

Although various cases of neuralgia and its treatments have been reported, not enough evidence is present to recommend a single type of treatment as the most effective. The patient we have dealt with experienced significant interferences in his daily life due to chronic allodynia, but the symptom could not be resolved via previously reported treatments. We report a case of which a patient who presented infraorbital neuralgia after trauma was successfully treated by a novel treatment strategy. Read More
