Comparative analysis of human papillomavirus detection by PCR and non-isotopic in situ hybridisation.

AIMS--To assess the relative diagnostic performance of the polymerase chain reaction (PCR) and non-isotopic in situ hybridisation (NISH) and to correlate these data with cytopathological assessment. METHODS--Paired analysis of human papillomavirus (HPV) detection was performed by PCR and NISH on exfoliated cervical cells from 122 women attending a routine gynaecological examination. PCR amplification followed by generic and HPV type specific hybridisation was compared with NISH on a parallel cervical smear.

Distribution of human papillomavirus types in genital lesions from two temporally distinct populations determined by in situ hybridization.

We examined 341 paraffin-embedded cervical tissues for human papillomavirus (HPV) DNA by in situ hybridization. The genital lesions examined represented tissue biopsies from two temporally distinct populations (1964 to 1965 and 1988 to 1989). Biotinylated probes to 14 different HPV types were used in our analysis: HPV types 6, 11, 16, 18, 31, 33, 35, 42, 43, 44, 45, 51, 52, and 56.

Comparative analysis of human papillomavirus detection by dot blot hybridisation and non-isotopic in situ hybridisation.

Aims: To determine the relative diagnostic performance of non-isotopic in situ hybridisation (NISH) and a dot-blot assay for detecting human papillomavirus (HPV) on exfoliated cervical cells; and to correlate the results with cytopathological assessment.

Methods: Cervical smears and cytological samples were obtained from 122 patients during the same clinical examination and the presence of HPV sequences determined by NISH and dot-blot analysis, respectively.

Results: Dot-blot analysis gave an autoradiographic signal in 15 of 121 (12.

Comparison of nucleic acid hybridization and cytologic examination for detection of human papillomavirus infection, with evaluation of two commercially available hybridization kits.

Human papillomavirus (HPV) infections were detected by analyzing exfoliated cervical cells for HPV DNA by use of nucleic acid hybridization; the results were correlated with cytologic findings on Papanicolaou smears. HPV infection was diagnosed in 154 women (20%) by either morphologic evidence on cervical smears or nucleic acid hybridization. Many of these women (38%; 58/154) exhibited Papanicolaou smears with no morphologic evidence of HPV infection.
