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...

Background: Cancer cervix is the most common cancer in women of the developing countries where screening facilities are inadequate. Cancer cervix is a preventable cancer due to its long pre invasive stage and availability of screening methods. Colposcopy is an in situ clinical examination of cervix with magnification and illumination. It is a clinical method that complements the laboratory meth...

BACKGROUND In Norway, women with negative or low-grade cervical biopsies (normal/CIN1) are followed up after six months in order to decide on further follow-up or recall for screening at three-year intervals. A high specificity and positive predictive value (PPV) of the triage test is important to avoid unnecessary diagnostic and therapeutic procedures whereas a low risk of high-grade disease a...

OBJECTIVE To identify alterations in the cytokine profile and microbial ecosystem of the vagina in association with cervical dysplasia. METHODS Demographics, lifestyle variables and Papanicolau (Pap) smear results of subjects presenting to the same site for gynecologic complaints, obstetric visits or colposcopy were prospectively recorded. Vaginal smear for Gram stain, aerobic and anaerobic c...

To evaluate the effectiveness of Human papillomavirus16/18 infection referral to colposcopy in cervical cancer screening for women aged 25 years and older in Chinese northwest region Shaan'xi province. A total of 2224 women were diagnosed with primary high-risk HPV infection by HPV-DNA genotyping technology during August 2014 to August 2015. A total of 1916 cases referred for colposcopy with hi...

BACKGROUND More than 2 million U.S. women receive an equivocal cervical cytologic diagnosis (atypical squamous cells of undetermined significance [ASCUS]) each year. Effective colposcopy triage strategies are needed to identify the minority of women who have clinically significant disease while avoiding excessive follow-up evaluation for others. METHODS The ASCUS/LSIL (i.e., low-grade squamou...

OBJECTIVE To provide a guideline for managing abnormal cytology results after screening for cervical cancer, to clarify the appropriate algorithms for follow-up after treatment, and to promote the best possible care for women while ensuring efficient use of available resources. OUTCOMES Women with abnormal cytology are at risk of developing cervical cancer; appropriate triage and treatment wi...

OBJECTIVE To examine the relationship between colposcopic anogenital findings and overall assessment of sexual abuse. DESIGN Prospective study. SETTING Regional hospital, Hong Kong. PATIENTS Seventy-seven children (mean age, 6.5 years; range, 6 months-16 years) referred consecutively for sexual abuse evaluation between July 1999 and June 2002 were included. MAIN OUTCOME MEASURES Colposc...

BACKGROUND Based on moderate quality evidence, routine pelvic examination is strongly recommended against in asymptomatic women. The aims of this study was to quantify the extent of routine pelvic examinations within specialized health care in Norway, to assess if the use of these services differs across hospital referral regions and to assess if the use of colposcopy and ultrasound differs wit...

BACKGROUND Women with HIV infection have a higher risk for cervical squamous intraepithelial lesions than do women without HIV infection, and the optimal regimen for cervical cancer screening in these women is uncertain. OBJECTIVE To assess the net health consequences, costs, and cost-effectiveness of various screening strategies for cervical neoplasia and cancer in HIV-infected women. DESI...
