HPV DNA in clinically different variants of oral leukoplakia and lichen planus

2004

Abstract Objectives Our objectives were to determine the prevalence of human papillomavirus (HPV) infection in oral leukoplakia (OL) and oral lichen planus (OLP) in comparison with that in healthy oral mucosa, also conditionally to age, gender, smoking, and drinking habits of patients, so as to investigate any possible association of HPV infection with a specific clinical variant of OL or OLP. Study design We did research on HPV DNA in 68 cases of OL (homogeneous form [H] in 45 cases and nonhomogeneous form [non-H] in 23 cases), and in 71 cases of OLP (nonatrophic/erosive form [non-AE] in 27 cases, atrophic/erosive form [AE] in 44 cases). HPV DNA was investigated in exfoliated oral mucosa c…

Human papillomavirus DNA in oral mucosal lesions

2002

This study determined the presence of human papillomavirus (HPV) DNA in oral mucosa cells from 121 patients with different types of oral mucosal lesions (13 squamous cell carcinomas, 59 potentially malignant lesions, 49 benign erosive ulcerative lesions) and from 90 control subjects. HPV DNA was detected by nested polymerase chain reaction, and genotype was determined by DNA sequencing. HPV prevalence was 61.5% in carcinomas, 27.1% in potentially malignant lesions, 26.5% in erosive ulcerative lesions, and 5.5% in control subjects. The risk of malignant or potentially malignant lesions was associated with HPV and was statistically significant. HPV-18 was found in 86.5% of HPV-positive lesion…

Detection of Human Papillomavirus DNA in Cervical Samples: Analysis of the New PGMY-PCR Compared To the Hybrid Capture II and MY-PCR Assays and a Two…

2004

ABSTRACT The PGMY-PCR for human papillomavirus (HPV) was evaluated, in parallel with nested PCR ( n PCR), in samples with noted Hybrid Capture II (HCII) and MY-PCR results. PGMY-PCR detected HPV DNA in 2.5% of HCII-negative-MY-PCR-negative samples and in 71.7% of HCII-positive-MY-PCR-negative samples; also, it detected the MY-PCR-negative- n PCR-negative types HPV-42, HPV-44, HPV-51, HPV-87, and HPV-89.

Atypical squamous cells of undetermined significance-favour reactive compared to atypical squamous cells of undetermined significance-favour dysplasi…

2005

Abstract Background and objectives: The current study compared the cervical cytological sub-category “atypical squamous cells of undetermined significance-favour reactive (AFR)”, recently recommended to be eliminated by the Bethesda system, to the sub-category “atypical squamous cells of undetermined significance-favour dysplasia (ASC-US)”, in terms of prevalence of coexistent squamous intraepithelial lesions of either low-grade (LSIL) or high-grade (HSIL) and rate of human papillomavirus (HPV) infection. Study design: One hundred women with AFR and 100 with ASC-US were consecutively included in the study. All patients underwent colposcopy, followed by biopsy when necessary, and were screen…
