In the case of an aggressive course of recurrent respiratory papillomatosis (RRP), adjuvant therapy can be used besides surgery. The aim of the study was to investigate the influence of vaccination with a quadrivalent vaccine against human papilloma viruses (HPV) types 6, 11, 16 and 18 on the course of RRP. Eleven subjects aged 13–46 years with a rapid(More)
BACKGROUND Although infection with Helicobacter pylori in children mostly induces asymptomatic chronic gastritis, the clinical outcome of H pylori infection is generally unpredictable. To identify the risk subgroup of infected children who can progress toward serious gastrointestinal disease, we assessed the prevalence of H pylori virulence genes cagA,(More)
The DNA genome of a novel HPV genotype, HPV-125, isolated from a hand wart of an immuno-competent 19-year old male was fully cloned, sequenced and characterized. The full genome of HPV-125 is 7,809-bp in length with a GC content of 46.4%. By comparing the nucleotide sequence of the complete L1 gene, HPV-125 is phylogenetically placed within cutaneotrophic(More)
Gammapapillomavirus (Gamma-PV) is a diverse and rapidly expanding PV-genus, currently consisting of 76 fully characterized human papillomavirus (HPV) types. In this study, DNA genomes of two novel HPV types, HPV179 and HPV184, obtained from two distinct facial verrucae vulgares specimens of a 64 year-old renal-transplant recipient, were fully cloned,(More)
Inverted papillomas (IPs) are the most frequent type of sinonasal papillomas. These benign but destructive lesions are known for their high recurrence rate, probably due to incomplete excision. Our aim was to investigate the frequency of human papillomavirus (HPV) infection in patients with IPs and in IPs associated with squamous cell carcinoma (IPsSCC) and(More)
Five main groups of commercial assays for the multiplex detection of alpha human papillomaviruses (HPVs) are currently available. DNA-based screening assays, which test for the presence of 13-14 HPVs without determination of HPV type, have been the standard for HPV detection in the last decade. Assays that combine testing for 14 HPVs and HPV-16 and HPV-18(More)
BACKGROUND Persistent infection with a subgroup of at least 15 high-risk human papillomavirus (HPV) genotypes is considered as a necessary although insufficient etiological factor in the development of cervical carcinoma. As a consequence, HPV testing has recently become an important part of the cervical carcinoma screening and detection algorithms. AIM(More)
The Hybrid Capture 2 HPV DNA Test (hc2) (Digene Corporation, Gaithersburg, MD) is at present the only FDA approved assay for routine detection of human papillomavirus (HPV) infections. A significant analytical inaccuracy of the hc2 near to cut-off was reported recently. To address this problem, 240 samples with repeatedly borderline/equivocal/indeterminate(More)
PURPOSE OF INVESTIGATION To compare the detection and distribution of HPV genotypes in paired cervical scrape samples and tumor tissue samples in patients with cervical cancer. METHODS Forty cervical scrape samples and 40 paired archival or fresh frozen tissue samples were collected from women with cervical cancer. Polymerase chain reaction with GP5+ and(More)
A novel PCR-restriction fragment length polymorphism assay (PCR-RFLP) was developed for sensitive detection and reliable differentiation of five low-risk human papillomavirus (lr-HPV) genotypes: HPV 6, HPV 11, HPV 42, HPV 43 and HPV 44, as well as differentiation of prototypic and non-prototypic HPV 6 genomic variants. The assay is based on the(More)
