Recently, different approaches for uncalibrated stereo have been suggested which permit projective reconstruction from multiple views. These use weak calibration which is represented by the epipolar geometry, and so no knowledge of the intrinsic or extrinsic camera parameters is required. In this paper we consider projective reconstructions from pairs of views, and compare a number of the avail...

This study was conducted to quantify by meta-analysis the validity of colposcopy in the diagnosis of early cervical neoplasia in order to assess the justification of its integral role in this regard. Eight longitudinal studies were selected, which compared correlation of colposcopic impression with colposcopically directed biopsy results. The prevalence of disease in the studies ranged from 40 ...

The performance of endocervical curettage (ECC) is a dispute in population screening programs. Data of 3,460 women referred to colposcopy examination and had completed pathological results in the Shanxi Province Cervical Cancer Screening Study I and II were reviewed. Among them, 0.6% and 2.7% women were identified as the histopathological confirmed high-grade squamous intraepithelial lesion or ...

In July 2012 a revised terminology on colposcopic examinations of the cervix uteri was adopted by IFCPC. Central aspect is a description of characteristics that should aid in the definition of the disease entity cervix uteri. The nomenclature is built up in such a way that the examiner can evaluate colposcopic criteria according to a specific scheme. Firstly it is assessed whether the colposcop...

The finding of virus particles by transmission electron microscopy (TEM) in fixed cervical and vaginal scrape material and their identification as papilloma viruses by negative staining is described. The colposcopic, cytological, and histological appearances in a group of 10 patients in whom virus particles were seen are discussed and the possibly considered of an association between papilloma ...

Based on observation sheets and the existing database in Obstetrics - Gynecology Department, we reviewed the outcome for patients diagnosed with neoplasic and preneoplasic lesions of the cervix that were examined in our clinic. Colposcopic diagnosis efficiency was analyzed retrospectively reported to the histopathologic diagnosis and to the results of other studies. Our results were similar to ...

Colposcopic diagnosis of 156 different lesions of the cervix was compared with histologic examination of the cervical punch biopsies. Colposcopy showed high degree of sensitivity and specificity (96% and 99.2%) in cases of carcinoma of the cervix. In cervical intraepithelial neoplasia (CIN) it showed a sensitivity of 82.8% and specificity of 49.6%, while in subclinical papilloma virus infection...

OBJECTIVE To assess the sensitivity and specificity of visual inspection of cervix for detection of precancerous and early cancerous lesions of cervix. METHODS In a Maternal and Child Health Care setting of New Delhi women underwent a detailed pelvic examination, visual inspection of cervix after 5% acetic acid application, cytology (pap smear), detailed colposcopic examination and colposcopi...

OBJECTIVES It has been hypothesised that ectopy may be associated with increased susceptibility to sexually transmitted infections (STIs). In this cross-sectional study, we wanted to explore the association between STIs (including HIV) and cervical ectopy. METHODS We included 700 sexually active young women attending randomly selected high schools in a rural district in KwaZulu-Natal, South A...
