| the utility of serologic testing for varicella in an adolescent population. | the purpose of this study was to determine what proportion of adolescents without a history of varicella are seropositive, and if serologic testing of this adolescent subpopulation is cost-effective. we identified 122 patients with 'no' or 'unknown' histories of chicken pox from our adolescent clinic. of these, 58 (48%) were found to be varicella zoster virus (vzv) seropositive. cost to the government for batched serologic testing of all unknowns was $682.65, while each adolescent vaccinated cos ... | 2001 | 11535319 |
| effects of a behavioral intervention, tai chi chih, on varicella-zoster virus specific immunity and health functioning in older adults. | both the incidence and severity of herpes zoster (shingles) increase markedly with increasing age in association with a decline in varicella-zoster virus (vzv) specific cell-mediated immunity (cmi). this study examined whether a behavioral intervention, tai chi chih (tcc), affects vzv specific immunity and health functioning in older adults who, on average, show impairments of health status and are at risk for shingles. | 2003 | 14508027 |
| history of chickenpox and shingles and prevalence of antibodies to varicella-zoster virus and three other herpesviruses among adults with glioma and controls. | whether viruses or immunologic factors might cause or prevent human brain cancer is of interest. statistically significant inverse associations of adult glioma with history of chickenpox and immunoglobulin g antibodies to varicella-zoster virus have been reported. the authors evaluate associations of immunoglobulin g antibodies to varicella-zoster virus and three other herpesviruses among 229 adults with glioma and 289 controls in the san francisco bay area adult glioma study (1997-2000). cases ... | 2005 | 15870157 |
| varicella vaccination of children in the united states: assessment after the first decade 1995-2005. | live attenuated varicella vaccine (strain oka) was approved for administration to healthy children in the united states in 1995. over the past 10 years, varicella vaccine has been given to millions of children, usually at ages between 12 and 18 months. in states such as california, michigan, and texas, there has been a marked decline in the number of reported cases of varicella. furthermore, there has been a 75% decrease in varicella-related hospitalizations across the united states, as well as ... | 2005 | 15911422 |
| the incidence and clinical characteristics of herpes zoster among children and adolescents after implementation of varicella vaccination. | the varicella-zoster virus (vzv) vaccine strain may reactivate to cause herpes zoster. limited data suggest that the risk of herpes zoster in vaccinated children could be lower than in children with naturally acquired varicella. we examine incidence trends, risk and epidemiologic and clinical features of herpes zoster disease among children and adolescents by vaccination status. | 2009 | 19536039 |
| risk factors of herpes zoster among children immunized with varicella vaccine: results from a nested case-control study. | previous studies of varicella-zoster virus reactivation in children have provided little information on potential risk factors. the aim of this study was to investigate the effects of race, chronic medical conditions and treatments, and recent vaccination, on the risk of herpes zoster (hz) in children vaccinated with one dose of varicella vaccine. | 2010 | 19952977 |
