This study was performed to differentiate vaccine-type strains from wild-type strains and determine the genotype of varicella-zoster virus (VZV) in 51 Korean children. A sequencing analysis of ORF 62 identified two cases of herpes zoster caused by the vaccine-type virus, without a previous history of varicella, 22 months and 5 months after VZV vaccination. The wild-type strain was identified in the remaining children. A genotype analysis of ORF 22 amino acids revealed genotype J in all children except one...

A 63-year-old man noticed hypogeusia after presenting hiccups for several days. He was serologically diagnosed with varicella-zoster virus (VZV) infection, but had no skin lesions typical of herpes (zoster sine herpete). Hypogeusia was confirmed by electrogustometry and the filter-paper disk method, which showed damage in the areas innervated by the cord of tympanum, glossopharyngeal nerve, and greater petrosal nerve. High signals in the nuclei of the solitary tract of the medulla oblongata and the enhancement of the bilateral intracranial segments of the cranial nerve IX and X complex were observed by magnetic resonance imaging (MRI)...

Human immunodeficiency virus (HIV)-1 directly affects the nervous system, causes distinct neurological symptoms, and indirectly results in opportunistic infections, which include herpes virus simplex (HSV)-1, HSV-2, varicella zoster virus, and cytomegalovirus encephalitis caused by immunodeficiency. Early HIV-1 invasion of the central nervous system is also possible, and acute encephalopathy is a potentially lethal complication. We encountered a case of fulminant encephalopathy as a primary presentation of acute HIV-1 infection, in which highly active antiretroviral treatment resulted in a full clinical recovery...

Skin findings during the initial month of life are ubiquitous. One study estimated that more than 95% of newborns have cutaneous findings, which often are distressing to parents but frequently are benign and self-limited. Among them are milia, cutis marmorata, congenital dermal melanocytosis, and the benign neonatal pustular eruptions (eg, benign cephalic pustulosis, erythema toxicum neonatorum, transient neonatal pustular melanosis). Clinicians need to recognize these benign skin conditions and differentiate them from more serious conditions, such as infectious pustular eruptions from bacterial, viral, and fungal causes, and inflammatory conditions, such as Langerhans cell histiocytosis...

Encephalitis is typically viral (approximately half of diagnosed cases) or autoimmune (about a quarter) with the remainder remaining undiagnosable at this time. All require general supportive care but only a minority requires intensive care admission - in these intubation, to protect the airway or to treat status epilepticus with anesthetic drugs, may be needed. In some dysautonomia with wide blood pressure fluctuations is the principal concern. Remarkably, in addition to supportive care, specific treatment options are available for the majority - immune-modulating therapy for those with autoimmune disorders, antiviral therapy for herpes simplex 1 and 2, and varicella-zoster encephalitis...

BACKGROUND AND OBJECTIVE: In 2006, routine 2-dose varicella vaccination for children was recommended to improve control of varicella. We assessed the safety of second-dose varicella vaccination. METHODS: We identified second-dose single-antigen varicella vaccine reports in the Vaccine Adverse Event Reporting System during 2006 to 2014 among children aged 4 to 18 years. We analyzed reports by age group (4-6 and 7-18 years), sex, serious or nonserious status, most common adverse events (AEs), and whether other vaccines were administered concomitantly with varicella vaccine...

BACKGROUND: The MRZ reaction (MRZR), composed of the three antibody indices (AI) against measles, rubella and varicella zoster virus and found positive in the majority of relapsing-remitting multiple sclerosis (RRMS) patients, is absent in other inflammatory neurological diseases (OIND). So far, it has been uncertain whether its differential diagnostic promise extends to patients with primary-progressive multiple sclerosis (PPMS). OBJECTIVE: To investigate the prevalence of MRZR in PPMS compared to RRMS and OIND patients...

BACKGROUND: Live vaccines are generally contraindicated on immunosuppressive therapy due to safety concerns. However, data are limited to corroborate this practice. OBJECTIVES: To estimate the safety of live vaccinations in patients with immune-mediated inflammatory diseases (IMID) or solid organ transplantation (SOT) on immunosuppressive treatment and in patients after bone-marrow transplantation (BMT). DATA SOURCES: A search was conducted in electronic databases (Cochrane, Pubmed, Embase) and additional literature was identified by targeted searches...

Previously we established reporter cell lines for human cytomegalovirus (HCMV) and varicella zoster virus (VZV) and identified several antiviral compounds against these viruses using the reporter cells. In this study, we found that one of the identified anti-HCMV compounds, a thienylcarboxamide derivative (coded as 133G4), was effective against not only HCMV but also VZV. The following findings indicate that 133G4 inhibits the activation of early gene promoters by HCMV IE2 and VZV IE62: i) 133G4 decreased the expression of HCMV early and late genes but not that of HCMV IE1/IE2 in HCMV-infected cells, ii) 133G4 inhibited the activation of several HCMV early gene promoters of transiently-transfected plasmids in HCMV-infected cells, and iii) in transient transfection assays, 133G4 decreased the activation of HCMV (or VZV) early gene promoters by HCMV IE2 (or VZV IE62) in the absence of other viral protein expression...

Herpes zoster (HZ) is a painful, blistering skin eruption in a dermatomal distribution caused by reactivation of a latent varicella zoster virus in the dorsal root ganglia (DRG). Post-herpetic neuralgia (PHN) is the most common complication of acute herpes zoster (AHZ).Severe prodrome, greater acute pain and dermatomal injury, and the density of the eruption are the risk factors and predictors for developing PHN. PHN has a substantial effect on the quality of life; many patients develop severe physical, occupational, social, and psychosocial disabilities as a result of the unceasing pain...

Infections of the central nervous system (CNS) with varicella zoster virus (VZV) is a rare occurrence after allogeneic hematopoietic stem cell transplantation. We herein report a case of VZV meningitis, radiculitis and myelitis that developed 8 months after cord blood transplantation, shortly after the cessation of cyclosporine and low-dose acyclovir. Although treatment with acyclovir did not achieve a satisfactory response, the patient was successfully treated with foscarnet. Our report indicates that VZV infection should be considered in allo-hematopoietic stem cell transplantation (HSCT) patients with CNS symptoms and that foscarnet may be effective for the treatment of acyclovir-resistant VZV infections of the CNS...

Ustekinumab, a monoclonal antibody that binds to the shared p40 subunit of interleukin (IL)-12 and IL-23, is approved in the USA and Europe for moderate to severe plaque psoriasis. There are concerns that biologic treatments like ustekinumab may lead to an increased rate of infections. We report a 77-year-old woman who developed varicella zoster virus meningitis 8 weeks after initiation of ustekinumab therapy because of plaque psoriasis. She presented clinically with sudden onset of fatigue, vertigo, nausea and epileptic seizures...

Varicella infection is common in children caused by varicella-zoster virus (VZV). VZV is known to cause cerebral arterial vasculopathy and antibody-mediated hypercoagulable state leading to thrombotic complications in children. Such complications in adults are very rare. We report three cases that represent the unseen face of primary varicella infection in adults. Simultaneous involvement of cortical venous sinus thrombosis and deep vein thrombosis leading to clot in right atrium and pulmonary embolism in first case; cortical venous sinus thrombosis in second case; and deep vein thrombosis in third case...

Herpes zoster (HZ) is caused by reactivation of the varicella zoster virus. Its main risk factor is increasing age and comorbidities. There are limited data on the characteristics of HZ in South America, especially in the elderly. We analyzed epidemiological and clinical characteristics of 340 patients over 60 years assisted for HZ, between June 2013 and May 2014. The average age was 74 years (60-100), 62% (210) had thoracic location; 75% (255) of the initial consultations were held in guards; 68% (143) had pain and vesicles, and 4% (14) only pain at baseline...
