39 Clinical Trials for Various Conditions
The purpose of this study is to determine the correct volume of lissamine green to use when assessing conjunctival staining, and to determine the time course needed to evaluate conjunctival staining after lissamine green has been instilled in the eye.
Recently, Indigo Carmine and Methylene Blue have been the standard agents to visualize ureteral jets during intraoperative cystoscopy. However, due to a national shortage of Indigo Carmine and Methylene Blue, there is a need to discover alternative IV and oral agents that are readily available and well tolerated when used for visualizing ureteral jets at the time of intraoperative cystoscopy. The aim of this study is to look at oral agents that have been studied such as pyridium (Phenazopyridine Hydrochloride) and riboflavin and compare them in a three-arm double-blinded randomized controlled pilot study using riboflavin, pyridium, and a placebo. The aim of the study is to provide evidence that both pyridium and riboflavin are effective and safe for staining urine to facilitate visualization of jets in evaluating ureteral patency at the time of intraoperative cystoscopy.
The FRDTM is easy to perform and does not require sophisticated laboratory technology and/or experienced pathologists for test result interpretation. Compared to the Pap smear and HPV test, the FRDTM enables clinicians to obtain test results immediately (within 60 seconds) after the screening. This empowers clinicians in making timely decisions on appropriate patient management, and facilitating patient compliance with follow-up procedures. In addition, the FRDTM requires minimal training and technical support. Due to its advantage of rapid visualization of abnormal cervical lesions (CIN2+) in a cost-effective way, health care professionals can make cervical cancer detection accessible to women worldwide, especially in regions with limited medical resources. This is a cross-sectional study to evaluate the clinical performance of Folate Receptor-Mediated Epithelium Staining (FRDTM) in detecting cervical neoplastic lesions (CIN2+).
To demonstrate that the Icare tonometer does not alter Keratometry readings, topography, or corneal staining. This would therefore allow intraocular pressure (IOP) testing to be done at any time during an exam, without affecting other testing. This may improve office-flow and spare patients from returning for another exam for additional testing.

This study compares contact lens comfortable wear duration, and signs and symptoms of contact lens discomfort, test versus control.
Specific Aims 1. Develop risk assessment scores for SCL wearers 2. Test the scoring algorithm in SCL wearers who present with adverse events 3. Explore targeted patient education to reduce risk behaviors associated with SCL wear.
This study will evaluate the response rate of MLN8237 in patients with histologically confirmed or clinically suspected metastatic neuroendocrine prostate cancer (NEPC). MLN8237 is an orally administered Aurora kinase A inhibitor that has demonstrated broad antitumor activity in vitro and in vivo. In preclinical models, aurora kinase inhibition resulted in dramatic and preferential anti-tumor activity in NEPC with suppression of neuroendocrine marker expression.
The whitening action of an investigative hydrogen peroxide/sodium fluoride containing mouth rinse will be evaluated through stain removal using mean Lobene Stain Index over 14 days compared to a currently marketed hydrogen peroxide containing whitening mouth rinse (Crest® 3D White Multi-Care Whitening Rinse, Glamorous White, Fresh Mint). A currently marketed toothpaste (Colgate® Cavity Protection) will be included as the negative control in order to compare to brushing alone. 225 healthy volunteers will be enrolled in this two week study. Volunteers who qualify to be in this study will have an equal chance of being assigned to one of the three treatment groups. Volunteers will have a total of 5 clinic visits including 1) screening, 2) baseline 3) Day 4 (after 3 days of use), Day 8 (after 7 days of use) and Day 15 (after 14 days of use). Volunteers will maintain a diary at home to record each treatment use. Examinations for oral hard/soft tissue assessment and extrinsic tooth stain after the subject brushes with water and floss will be completed at Baseline and repeated at Clinic Visits 3, 4, and 5, which are on Days 4, 8 and 15 post baseline (i.e., after 3, 7, and 14 days of product use).
The purpose of this study is to more objectively evaluate potential lens-material/care solution bio-incompatibilities. We will do this by measuring corneal staining and the amount of fluorescein dye diffusion into the eye.
The purpose of this study is to measure the relative "barrier" function of the top layer of the cornea (called the epithelium), or the degree to which the cornea can prevent the penetration of the colored dye sodium fluorescein into the eye. This is a clinical investigation of the effect on corneal barrier function following wear of two contact lens materials and two contact lens care systems, approved for marketing in the US by the Food and Drug Administration. These contact lenses will be worn for two hours, following soak in one of two marketed contact lens disinfecting solutions. Approximately 25 young, adapted contact lens wearers will participate.
