Filter by:Optical Coherence Tomography (OCT) is a technology using harmless near infra-red light scatter to produce an image. Prior studies with OCT have demonstrated that OCT of the uterine cervix can differentiate between grades of pre-invasive and invasive cervical disease and cancer. This study will evaluate the ability of the NIRIS 1300e imaging (OCT) system to detect pre-invasive cervical disease and cervical cancer.
This study will consist of 300 women aged 18-50 years. The study will show that a new therapeutic human papillomavirus (HPV) vaccine designed to regress a precancerous condition called high-grade squamous intraepithelial neoplasia (HSIL)is safe. HPV is known to cause cervical, vaginal, oral, and anal cancers. This novel vaccine will consist of a synthetically made fragment of HPV protein called E6 and yeast extract called Candin®. Previous studies have revealed that immune response to E6 is important in fighting HPV. We also know that injecting Candin has anti-HPV effect since it has been used to treat common warts which are caused by different types of HPV. The current standard treatment for HSIL is loop electrical excision procedure (LEEP). The immune system is the part of the body that fights infection and cancer. This research study will also examine the immune response to the vaccine and its effectiveness in regressing HSIL. Volunteers would be eligible to enroll in the study if they have had a recent Papanicolaou (Pap) smear result indicating HSIL or "Cannot rule out HSIL", and if they meet the inclusion/exclusion criteria. Subjects will be eligible to receive vaccinations if biopsy confirms HSIL. A series of four vaccinations will be given roughly 3 weeks apart, and LEEP will be performed at the end of the study approximately 12 weeks after the last vaccination.
The purpose of this study is to understand the effect of using oral U-relax on HPV infected women for vaginal environment health promotion, and the HPV DNA Test Index change from positive to negative. Long-term infection of HPV is associated with cervical cancer. U-relax contains Lactobacillus GR-1 and Lactobacillus RC-14 and has been approved of its benefits on treatment of BV, UTI, IBD and can improve vaginal environment health. Patients with positive result of HPV DNA test have no appropriate and aggressive treatment to reduce the risk of cervical cancer. This clinical trial tries to reveal the influence of oral U-relax and patients with HPV DNA test positive result.
This study will evaluate the safety of a novel recombinant human papillomavirus bivalent ( types 16 and 18 ) vaccine ( Yeast ) with different dose in healthy females between 9-45 years of age at enrollment.
The purpose of this study is to evaluate the impact of a school-based Human Papillomavirus (HPV) vaccination program to determine if the combination of increased disease and vaccine education coupled with the removal of barriers will positively impact the HPV vaccination uptake and completion rates among students.
The purpose of this study is to develop and implement a community based preventive healthcare model using cervical cancer screening as the target medical intervention. The investigators will first conduct 2 pilot studies to refine their preventive healthcare model based on the principles of community based participatory research (1000 participants). The investigators will then apply the model to screen 9000 women for cervical cancer over a period of 7-9 days. This 10,000 patient trial will explore the ability of a community to conduct their own screening program to identify who needs medical intervention based on self-collection and centralized high-throughput low cost human papillomavirus (HPV) testing.
The investigators tried to know whether a virus causing cervical cancer could be detected in menstrual blood and to set up a experimental setting to detect the virus.
The use of HPV testing in cervical screening has raised concerns about the effect of a positive HPV result on women's psychological well being. This is a nested psychosocial study of the COCY trial (IRB No. UW 09-377; PI: Prof Hextan Ngan), with the aim to evaluate the psychosocial impact of HPV positivity on Hong Kong Chinese women and the modulating effects of educational intervention on such impact. Potential participants are identified among those who have joint the COCY trial. Participants will be randomized into two groups, namely the control group or intervention group. The control group participants will receive their smear results and an HPV leaflet by post. The intervention group will receive the leaflet and a counseling session on HPV. Self-administered questionnaires will be used to assess participants' psychological condition at the receipt of the smear results and at two months afterward. It is hypothesized that the level of emotional distress measured at smear result notification will be greater than that at two months afterward for all participants. Furthermore, participants in the intervention group will have lower psychological distress than those in the control group at two months after the receipt of their smear results.
Two human papillomavirus vaccines are now commercially available. No clinical data exist regarding: - The immunogenicity and safety of Gardasil and Twinrix when co-administered. - The immunogenicity and safety of Cervarix when administered to subjects previously vaccinated with Gardasil. The main objective of the first phase of this clinical trial was: • To assess and compare the immunogenicity of Gardasil and Twinrix Junior when co-administered or administered at one month interval according to a 0, 6 month schedule to 9-10 year-old girls. The main objective of the seconde phase of this clinical trial is: • To determine the effect of a booster dose of Gardasil or Cervarix on HPV antibodies when given 42 months post-vaccination of 9-10 year-old girls with two doses of Gardasil. Study Design & Duration: Experimental Design: Blind for the third HPV vaccine dose, randomized, single centre study with two treatment groups. Duration of the study: Participants will be followed for the duration of 10 years post-primary vaccination. Number of Centres: One Center.
The purpose of this study is to determine sustained immunogenicity of the quadrivalent vaccine 'Gardasil', 48 months after initial vaccination, among HIV-1 infected boys and girls age 9-14 years. This age range is within the World Health Organization (WHO) stipulated guidelines for national programs for the vaccine.
