title: [HPV infection of the uterine cervix by cytodiagnosis, histodiagnosis and dot blot hybridization method].
abstract: Human papilloma virus (HPV) infection is diagnosed by morphological methods (including cytodiagnosis, histodiagnosis and electron microscopy) and DNA diagnostic methods. One of the DNA diagnostic methods, Dot blot hybridization (DBH), is generally regarded to be superior to the morphological methods in terms of specificity and sensitivity. There have recently been reports showing that such morphological methods as cytodiagnosis [for koilocytotic atypia (KC) or koilocytosis] and histodiagnosis are best for HPV detection in laboratories because they have better sensitivity, and are cheaper, and procedurally simpler than the DBH method. We compared detection rates by morphological methods (cytodiagnosis and histodiagnosis) and the DBH method. (Materials and Methods) The subjects were 377 patients who came to the Department of Obstetrics and Gynecology of Juntendo University Urayasu Hospital and had abnormal findings in the uterine cervix by cytodiagnosis of colposcopy. Uterine cervix swabs were scraped during colposcopic examination, and specimens for Papanicolaou and Giemsa staining were prepared on 2 slides. Scraping was again performed for the DBH (Vira pap. and type, Toray Industries, Inc.) method using swabs specified for the kit, and cells were obtained in a collection kit. At the same time, at least 3 sites including, possible atypical conversion zones, were biopsied, followed by paraffin embedding and hematoxylin-eosin staining of the specimens. (Results) 1) Comparison of detection rates by cytodiagnosis and the DBH method The positive rates by the DBH method were determined according to cytodiagnostic category in 377 patients. HPV-DNA was detected in every category and in 86 (22.8%) of all of the patients.(ABSTRACT TRUNCATED AT 250 WORDS)
