Ramsay Hunt syndrome a case report and review of literature [PDF]

, 2013
This is a case report of a rather rare disorder i.e. Ramsay Hunt syndrome.  This is caused by Varicella zoster infections involving geniculate ganglion of facial nerve.  This syndrome is manifested by the presence of blebs in the external auditory canal,

N-cadherin acts in concert with Slit1-Robo2 signaling in regulating aggregation of placode-derived cranial sensory neurons [PDF]

, 2009
Vertebrate cranial sensory ganglia have a dual origin from the neural crest and ectodermal placodes. In the largest of these, the trigeminal ganglion, Slit1-Robo2 signaling is essential for proper ganglion assembly.

Spatiotemporal distribution of neural crest cells in the common wall lizard Podarcis muralis

Developmental Dynamics, EarlyView.
Abstract Background Neural crest cells (NCCs) are migratory embryonic stem cells that give rise to a diverse set of cell types. Here we describe the dynamic distribution of NCCs in developing embryos of the common wall lizard Podarcis muralis inferred from 10 markers.

A Pediatric Case of Ramsay Hunt Syndrome

Case Reports in Otolaryngology, 2014
Ramsay Hunt syndrome (RHS) is characterized by facial paralysis, inner ear dysfunction, periauricular pain, and herpetiform vesicles. The reported incidence in children is 2.7/100,000. The pathogenesis involves the reactivation of latent varicella zoster

Embryonic Intravitreous Injection in Mouse

Bio-Protocol, 2018
Axons of retinal ganglion cells (RGCs) relay visual information from the retina to lateral geniculate nucleus (LGN) and superior colliculus (SC), which are two major image-forming visual nuclei. Wiring of these retinal projections completes before vision

Brain Imaging Phenotypes Associated with Polygenic Risk for Essential Tremor

Movement Disorders, EarlyView.
Abstract Essential tremor (ET) is a common movement disorder with a strong genetic basis. Magnetic resonance imaging (MRI), particularly diffusion‐weighted MRI (dMRI) and T1 MRI, have been used to identify brain abnormalities of ET patients. However, the mechanisms by which genetic risk affects the brain to render individuals vulnerable to ET remain ...

Ramsay Hunt Syndrome in a Patient with Rheumatoid Arthritis after Treatment with Infliximab

Case Reports in Rheumatology, 2014
A 39-year-old female patient with rheumatoid arthritis developed Ramsay Hunt syndrome after infliximab treatment. This condition is caused by the reactivation of varicella zoster virus infection in the geniculate ganglion of facial nerve in the host’s ...

Cholinergic System Changes in Dopa‐Unresponsive Freezing of Gait in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Freezing of gait (FoG) is a debilitating mobility disturbance that becomes increasingly resistant to dopaminergic pharmacotherapies with advancing Parkinson's disease (PD). The pathophysiology underlying the response of FoG to dopaminergic treatment is poorly understood.

Surgical Outcomes Comparison of Spontaneous Middle Cranial Fossa Cerebrospinal Fluid Leaks: Systematic Review and Meta‐analysis

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Spontaneous cerebrospinal fluid (sCSF) leaks of lateral skull base have little consensus on optimal management. We synthesized and evaluated current literature via systematic and meta‐analysis to compare the success rates and complications of the different surgical techniques for middle cranial fossa (MCF) sCSF leak repair.

Facial nerve schwannoma: Case report and brief review of the literature

Radiology Case Reports, 2023
Schwannomas are rare nerve sheath tumors that can occur throughout the body, and are symptomatic based on location, size, and impingement on adjacent structures. These tumors are often benign lesions and occur sporadically or from genetic conditions such
