Lidocaine Spray vs Coughing for Pain Relief During Colposcopy

Cervical cancer is the third most common genital cancer worldwide. The diagnosis of cervical cancer is performed with the cervical biopsy which is guided by the colposcopy. The colposcopy guided cervical biopsy creates pain and several methods have been reported to overcome the pain related with this procedure. Local anesthetic agent injection into the cervix has been studied and found to be effective and also, forced coughing was compared with local anesthetic injection and it...

Oral Misoprostol Before Endometrial Biopsy

An endometrial biopsy involves a thin tube being passed through the cervix (opening of the uterus) to obtain a sample of the lining of the uterus. Sometimes there may be discomfort with this procedure especially if the cervix is not dilated or opened. Previous research has suggested that taking a drug called misoprostol may help the cervix to start to dilate or open. This study will see if misoprostol will help open the cervix for an endometrial biopsy, to lessen the discomfort...

Investigate light scattering differences in tumorigenic and nontumorigenic cells. Develop and implement quantitative and sensitive methods for measuring morphological properties. Clinical measurements.

Immediate Treatment vs Colposcopic Follow-up for Biopsy-Proven CIN 1

This study looks at immediate treatment of a cervix with CIN 1 versus regular six-month follow-up with colposcopy and treatment if CIN 1 progresses.

High Resolution Digital Imaging of the Uterine Cervix

This study was designed to gather digital pictures of the cervix and correlate it to its histopathology, and then use those relationships to teach a computer how to objectively find cervical dysplasia and cancer.

Diagnostic and Prognostic Value of p16INK4a Expression in Low Grade Squamous Intraepithelial Lesions of the Cervix.

P16INK4a has recently been described as a surrogate marker for HR-HPV associated squamous and glandular intraepithelial lesions of the cervix. The immunohistochemical staining pattern of p16INK4a in high grade intraepithelial neoplasia of the cervix (CIN 2 and 3) is diffuse, whereas in CIN 1 different staining patterns (diffuse, sporadic, focal or negative) can be seen. The aim of our study is to find out whether the p16INK4a staining pattern of CIN 1 is able to predict the o...


A Non-Invasive Cervical Cancer Screening Modality: A Pilot Study

Cervix cancer is a major global health concern. A way to screen and immediately treat precancerous lesions (Screen-and-Treat) is greatly needed. Developed by MobileOCT, polarized difference imaging and conventional imaging are used to identify suspicious lesions. We aim to compare this non-invasive method with colposcopy. Patients at the Dickens Clinic will have 3-5 minutes of non-invasive imaging before colposcopy. Pathology will be compared both to colposcopy impression versu...

Human Papillomavirus (HPV) Testing to Improve Cervical Cancer Screening in the Mississippi Delta

Background: - Cancer of the cervix (bottom third of the uterus, or womb) can be prevented by regular Pap tests (also called Pap smears), which check for changes in the cells of the cervix. Because many women in the United States have regular Pap smears, cervical cancer is not common in this country. However, the disease is common among women in the Mississippi Delta because of poor participation in screening programs. - The major causes of cerv...

Role of Oral Tramadol 50 mg in Reducing Pain During Colposcopy-directed Cervical Biopsy

The study objective is to evaluate the effectiveness of oral tramadol 50 mg in reducing pain during the colposcopy-directed cervical biopsy.half of the patients will receive oral tramadol tablets and the other half will receive a placebo.

Post Colposcopy Management of ASC-US and LSIL Pap Tests

There is weak evidence supporting optimal follow-up of women with ASC-US or LSIL cytology found to have low grade disease or normal findings at initial colposcopy. Surveillance options include continued colposcopy, discharge with Pap testing, or HPV testing at 12 months. The investigators performed a pilot randomized controlled trial (RCT) comparing these 3 follow-up policies. Study objectives are to determine the feasibility of an RCT and to compare the incidence of >/=HSIL in...

Spectroscopic Evaluation of Cervical Neoplasia

The overall objective of this study is to evaluate whether fluorescence and reflectance spectroscopy can improve the ability to detect the presence of premalignant lesions on the cervix. The specific aims of the study are: - To compare information obtained from fluorescence and reflectance spectroscopic measurements of the cervix with standard methods for detecting cervical pre-cancers. - To validate previously developed algorithms for discriminating between...

Cervical Cancer Early Endpoints and Determinants

This study, conducted by the National Cancer Institute and the University of Oklahoma, will look for changes in cervix cells and other samples that may be signs of cervical disease. Human papilloma virus, or HPV, is a common infection of the genitalia in women that usually goes away by itself. If HPV infection does not go away, it might turn into cancer of the cervix, although this is rare. This study will examine why many HPV infections go away and why a few persist and lead...

Using Infrared Spectroscopy for Diagnosis Severity of Nonalcoholic Fatty Liver Disease

The main objective of this study is to evaluate the ability of infrared spectroscopy to discriminate simple hepatic steatosis from NASH

Randomized Clinical Trial on Clinical Management of ASCUS and LSIL (ALTS)

Approximately 65 million Pap smears are performed each year in the United States. The vast majority of results are negative (no abnormality identified) but about 5 percent to 8 percent are reported as abnormal. Most low-grade changes regress spontaneously; only a minority of such lesions would progress to a cancer precursor without treatment. However, there is no way to determine morphologically which patients are at risk or progression. Therefore, both high- and low-grade lesi...

Identification of Liver Tumours Using BIP - Biopsy System

This clinical device investigation is conducted by performing liver biopsies using the BIP - Biopsy Tool. The aim is to assess the feasibility of bioimpedance spectroscopy based biopsy tool guidance method and test how well BIP biopsy system is able to distinguish liver tumours from surrounding tissue. In addition, user feedback is obtained to improve the usability of the investigational device. The study does not affect the traditional treatment procedure and only the patients...

Music and Colposcopy in Women With Cervical Dysplasia.

To assess the effect of music during colposcopy on women´s anxiety.

Pilots of Self-Collection for HPV DNA Detection

This study will evaluate a method of testing for human papillomavirus (HPV) DNA. For women who have had Pap test results that are abnormal, a new test can be done for HPV, that is, viruses that sometimes cause bumpy or flat warts. Such infections all usually disappear by themselves in 1 or 2 years if someone's Pap test shows a mild abnormality. But if the HPV does not go away, the infection can slowly lead to cancer of the cervix. Through this study, researchers will examine pa...

The SAFE Study: Satisfaction and Adherence to Follow-Up With Colposcopy Exams

This study is intended to improve the patient experience of communication of colposcopy results and follow-up recommendations to patients. Current practice involves results being forwarded from the colposcopy clinic to the family or referring physician who then informs the patient. We are testing an intervention informed by focus groups in which a trained colposcopy nurse (patient liaison) directly contacts patients with their results and follow-up recommendations while providi...
