This clinical note describes a case report where the patient notices that one of symptoms suffered during COVID-19 infection is mononeuropathy branches maxillary nerve, reviewing in literature findings affinity coronavirus to nerve fibers.

The nerve fiber distribution in the epidermis of the hairless rat skin was studied light microscopically by means of zinc iodide-osmium tetroxide staining. Two different morphological types of free nerve fiber endings could be detected: clusters of relatively thick nerve fibers stretched up through the spinous layer up to the granular layer sending off terminal branches. In addition, many solit...

The functional properties of cutaneous afferent fibers were investigated 1-15 mo after nerve lesions, which allowed regeneration into denervated skin. After crushing or transection and resuturing the rat sural nerve, ongoing activity and responses to cold, heat, and mechanical stimuli presented to the denervated skin or to the nerve distal to the lesion were examined in 273 A-fibers and 211 C-f...

Afferent A- and C-fibers regenerating into a nerve following peripheral nerve injury are exposed to inflammatory mediators released by Schwann cells, resident and invading macrophages, and other inflammatory cells. Here we tested the hypothesis that ongoing and evoked activity in these afferent fibers are enhanced by a mixture of inflammatory mediators [inflammatory soup (IS)] applied to the in...

We investigated the distribution and navigation of periprostatic nerve fibers and constructed a 3-dimensional model of nerve distribution. A total of 5 cadaver specimens were serially sectioned in a transverse direction with 0.5 cm intervals. Hematoxylineosin staining and immunohistochemical staining were then performed on whole-mount sections. Three representative slides from the base, mid-par...

Although the pelvic autonomic plexus may be considered a mixture of sympathetic and parasympathetic nerves, little information on its composite fibers is available. Using 10 donated elderly cadavers, we investigated in detail the topohistology of nerve fibers in the posterior part of the periprostatic region in males and the infero-anterior part of the paracolpium in females. Neuronal nitric ox...

Perivascular innervation of the mesenteric arteries of 7-week-old and 6-month-old spontaneously hypertensive rats and normotensive Wistar-Kyoto rats was examined. The densities of neuropeptide Y-containing nerve fibers and adrenergic nerve fibers were increased in the distal regions of mesenteric arteries of spontaneously hypertensive rats as compared with findings in Wistar-Kyoto rats. However...

The periodontal ligament has a rich sensory nerve supply which originates from the trigeminal ganglion and trigeminal mesencephalic nucleus. Although various types of mechanoreceptors have been reported in the periodontal ligament, the Ruffini ending is an essential one. It is unknown whether the distribution of periodontal nerve fibers in deciduous teeth is identical to that in permanent teeth...
