Although varicella zoster virus latency has been demonstrated in several sensory ganglia, herpes zoster usually effects only one single, either left or right, dermatome in half of the body. In immunocompromised patients, more than one contiguous unilateral dermatome may be involved. Bilateral non-contiguous herpes zoster, also termed herpes zoster duplex, is rarely reported. Chronic varicella z...

Specific IgM varicella-zoster antibody was detected in "convalescent" sera from 20 out of 40 patients (50%) with herpes zoster infections. Since these were not primary infections with varicella-zoster virus, it seems that detection of IgM antibody specific for a particular virus may not differentiate a primary infection from secondary infections with that virus.

Herpes zoster infection occurs owing to reactivation of varicella zoster virus and classically manifests as a vesicular eruption involving a single dermatome. Disseminated herpes zoster - defined as having greater than twenty vesicles outside the primary or adjacent dermatome - is uncommon and typically occurs in immunocompromised individuals. Central nervous system complications during or foll...

background: varicella zoster virus (vzv) causes chickenpox in children and zoster (zona) in the elderly. using rflp-pcr method for detection of vzv specific snps orf38, 54 and 62 could  distinguish the profile of vzv isolates. the aim of this study was to investigate enzymatic digestion pattern of vzv orf38 and orf54 in chickenpox patients using rflp technique. methods: thirty-eight chickenpox ...

this study aimed to investigate the frequency of varicella zoster virus (vzv) in benign and malignant breast tumors. a total of 24 carcinomas and 24 fibroadenomas paraffin embedded tumoral tissue samples were obtained from the pathology sections of toos and firoozgar hospitals in tehran, iran. all samples were collected from patients from june 2011 to february 2012. dna was extracted from all s...

INTRODUCTION An infection by herpes zoster virus is a common and important cause of encephalitis. Herpes zoster virus encephalitis if not treated promptly can result in significant morbidity and mortality. The diagnosis of herpes zoster virus encephalitis is based on clinical history, examination, neuroradiological imaging (magnetic resonance imaging and/or computed tomography scan), cerebrospi...

Varicella results from a primary infection with the varicella virus while herpes zoster is caused by a reactivation of a latent infection. Dissemination of herpes zoster is uncommon in immunocompetent individuals. Reports of disseminated herpes zoster in children are even less common than in adults. An unusual case of disseminated herpes zoster ophthalmicus in an 8-year old immunocompetent blac...

In a search for past or present infection with herpes viruses, serum antibody titres to herpes simplex type 1 virus, cytomegalovirus, and varicella-zoster virus were measured by complement fixation test in 58 patients with achalasia. Serum was also taken from 40 age and sex matched patients without oesophageal symptoms who formed a control group. All titres were low, and those for herpes simple...

Varicella zoster virus fetopathy occurs in infants after infection with varicella-zoster virus from mother during the fi rst two trimesters of pregnancy. The authors describe the case of a female infant, aged 4 months, which came under observation for neuro developmental delay for chronological age. Neurological exam, abnomalities detected on ophthalmologic examination, maternal history of gest...

Reactivation of latent Varicella-Zoster virus may cause various neurological complications including meningitis, encephalitis, myelitis, vasculopathy resulting in stroke and pseudotumor cerebri. It occurs mainly in elderly or immunocompromised patients and is very rare in children. We report a 4-year and 6-months old immunocompetent boy who developed encephalitis and cerebellites, due to reacti...
