Primary Sclerosing Cholangitis in Children
Recruiting
Primary sclerosing cholangitis (PSC) is a rare liver disease that damages the liver's bile ducts. Bile ducts are tiny tubes that carry bile from the liver to the small intestine. Bile is a liquid produced by the liver that helps us absorb and use the nutrients in the food we eat. In people with PSC, the bile backs up into the liver and will damage it, causing scarring of the liver. The purposes of this study are to: * Collect medical and other data to learn more about PSC, how it progresses, a... Read More

A Prospective Database of Infants With Cholestasis
Recruiting
Biliary atresia, idiopathic neonatal hepatitis, and specific genetic cholestatic conditions are the most common causes of jaundice and hyperbilirubinemia that continue beyond the newborn period. The long term goal of the Childhood Liver Disease Research Network (ChiLDReN) is to establish a database of clinical information and plasma, serum, and tissue samples from cholestatic children to facilitate research and to perform clinical, epidemiological and therapeutic trials in these important pediat...

Self-collection for HPV Testing to Improve Cervical Cancer Prevention (SHIP) Trial (LMI-001-A-S03)
Recruiting
This clinical trial evaluates the use of self-collected vaginal samples for human papillomavirus (HPV) testing in patients referred for a colposcopy and/or cervical excisional procedures to improve cervical cancer prevention. HPV is a common virus which usually causes infections that last only a few months, but sometimes can last longer. HPV is known to cause a variety of cancers including cervical cancer. Even though there are ways to detect cervical cancer, many individuals are not diagnosed.... Read More
