Herpes zoster ophthalmicus occurs when the latent varicella zoster virus (VZV) reactivates in the trigeminal ganglion and ophthalmic branch of the trigeminal nerve. In the elderly, there is a sharp increase in the tendency of secondary skin bacterial infections occurrence due to the deterioration of capabilities of self-care and changed sanitation. We present a case of patient who developed phl...

Varicella-zoster virus (VZV) is a human alphaherpesvirus that infects sensory ganglia and reactivates from latency to cause herpes zoster. VZV replication was examined in human dorsal root ganglion (DRG) xenografts in mice with severe combined immunodeficiency using multiscale correlative immunofluorescence and electron microscopy. These experiments showed the presence of VZV genomic DNA, viral...

Objetivo: Determinar la influencia del Covid-19 en reactivación de Herpes Zoster provocando Síndrome Ramsay Hunt. Método: Revisión sistemática mediante estudio descriptivo artículos científicos, escritos inglés, español y portugués publicados entre 2018 2022. Resultados conclusiones: Se ha dado un aumento incidencia virus herpes zoster, el año 2020 brasileño encontraron 35,4% los diagnósticos z...

Herpes zoster-associated urinary retention is an uncommon event related to virus infection of the S2-S4 dermatome. The possible major reasons are ipsilateral hemicystitis, neuritis-induced or myelitis-associated virus infection. We report a case of a 65-year-old immunocompetent female patient who presented an acute urinary retention after four days under treatment with valacyclovir for gluteal ...

The subclass specificities of antiviral immunoglobulin G (IgG) produced in response to herpes simplex and varicella-zoster virus infections were investigated. IgG1 and IgG3 with anti-herpes simplex virus activity were seen in patients with primary and reactivated disease, as well as in healthy seropositive subjects and in immunoglobulin preparations. IgG4 was occasionally seen alone or together...

OBJECTIVES The history behind the current understanding of the varicella-zoster virus and its relationship to the pain conditions caused by shingles and postherpetic neuralgia are reviewed. The framework for the current conceptualization is Hope-Simpson's latency hypothesis. Data from recent work in virology, neuroanatomy and epidemiology are reviewed, as is work using varicella-zoster virus-in...

Standard cell culture and centrifugation culture were compared for the isolation of varicella-zoster virus from 337 clinical specimens. Of a total of 85 (25%) positive specimens, 67 (78.8%) were positive by centrifugation culture alone and 18 (21.2%) were positive by both methods. When epithelial cells from the specimen were included in the vial inoculum, these cells stained positive and increa...

Lymphadenitis caused by non-tuberculous mycobacteria is an uncommon manifestation in immunocompetent individuals. Here, we report a case of Mycobacterium fortuitum infection in a previously healthy 9-year-old patient who developed cervical lymphadenitis evolving to a suppurative ulcer associated with a varicella-zoster virus infection. We discuss the relationship between the varicella-zoster vi...

Glycoprotein gp118, one of the major glycosylated proteins specified by varicella-zoster virus, is biologically of great importance since it possesses an epitope which elicits a complement-independent neutralizing antibody response. To purify this glycoprotein from a Nonidet-solubilized extract of varicella-zoster virus-infected cells, we examined its affinity to a variety of ligands, including...

Vernet syndrome involves the IX, X, and XI cranial nerves and is most often attributable to malignancy, aneurysm or skull base fracture. Although there have been several reports on Vernet's syndrome caused by fracture and inflammation, cases related to varicella-zoster virus are rare and have not yet been reported in South Korea. A 32-year-old man, who complained of left ear pain, hoarse voice ...
