A study of 318 patients with tubal infertility and a control group of 200 unselected infertile women yielded 14 (4.4%) and 1 (0.5%), respectively, with precancerous lesions of the cervix uteri. The one patient in the control group with severe dysplasia was later shown to have tubal infertility. The overall incidence of premalignant lesions of the cervix uteri as reported to the National Cancer ...

Cervical human papillomavirus (HPV) infection is a dangerous disease, whose subtypes exhibit different distribution patterns in particular countries, regions, and races. In this study, the HPV distribution in patients with cervical precancerous lesions in Western China was investigated to assess a probability for prevention of cervical cancer and the clinical application of an HPV vaccine in Ch...

BACKGROUND Most squamous cell anal cancers and precancerous lesions are attributed to human papillomavirus (HPV) infection. By preventing HPV infection, quadrivalent HPV vaccine (qHPV) reduces risk of anal cancer/precancerous lesions in young men who have sex with men (MSM) without history of anal cancer/precancerous lesions. In our practice, many persons with history of precancerous anal lesio...

Ovine pulmonary adenocarcinoma (OPA) was studied in the lungs of 15 naturally-affected sheep (9 with classical and 6 atypical lesions) by transmission electron microscopy. Two lung samples from normal sheep were used to develop the ultrastructural criteria. Pathologic lesions consisted of focal-multifocal to coalescent nodules or masses in the cranioventral or diaphragmatic lobes. Ultrastructur...

Lymphadenopathy is most commonly encountered problems in clinical practice. Various etiological factors can cause lymphadenopathy. Cytomorphological study of lymphadenopathy a window for diagnosis many disease processes. Aspiration cytology provides reliable, safe, rapid and economical method screening the patients with accuracy. It differentiate neoplastic from non-neoplastic lesions therefore...

Bowen's disease, Keira's erythroplasia and bowenoid papulosis are currently classified as precancerous penis lesions associated with human papillomavirus (HPV). The diagnosis treatment of is a unique challenge. Most our knowledge about these diseases based on small, non-randomized retrospective studies due to the rarity conditions low incidence penile cancer. article provides an overview most s...

A 3-D optical imaging system based on active stereo vision and motion tracking is built to track the motion of patient and to register the time-sequenced images of cervix recorded during colposcopy. The imaging system is evaluated by examining human subjects in vivo before routine colposcopy examination procedures. The system tracks the motion of patient accurately. The temporal kinetics of the...
