The goal of this clinical trial is to learn if an FDA approved drug, Ceftriaxone, given intermittently, can treat people between 18 and 75 years old with a history of Lyme disease, who are still experiencing persistent or returning symptoms after they have completed treatment. The main questions it aims to answer are: - Will giving Ceftriaxone approximately every 5 days for 6 weeks be safe and well tolerated when compared to a group that receives placebo (a look-alike substance that contains no drug)? - Will giving Ceftriaxone improve symptoms? Participants will be asked to do the following: - Come to the clinic approximately every 5-6 days to receive...
The main objective of this study is to evaluate the safety, performance, and clinical benefits of the Persona Keel cementless and cemented knee.
The study is a prospective, first-in-human, multi-center, non-randomized, single-arm study to assess the safety and efficacy of the CEM-Cage used with the CEM-Plate in patients who are appropriate candidates for a 2-level anterior cervical discectomy and fusion (ACDF). Fifty patients will be enrolled in the study and, after undergoing a 2-level ACDF, will be evaluated at 4 weeks, 3 months, 6 months, 12 months, 18 months, and 24 months.
Systemic lupus erythematosus (SLE) and mixed connective tissue disease (MCTD) are long-term autoimmune diseases in which the immune system attacks parts of the body. The abnormal immune reaction causes inflammation of and damage to various body parts and can affect joints, skin, kidneys, heart, lungs, blood vessels, and the brain. SLE and MCTD often affect young women, especially black and Hispanic women, and there is no known cure. Knowing more about SLE and MCTD will help in developing new and effective treatments. The purpose of this study is to characterize immune system abnormalities, genetic components, and disease progression in people with SLE and MCTD.
Background: - Salivary glands in and around the mouth and throat make saliva. Salivary gland disorders can affect a person s quality of life. Studying people who have a disease that affects their salivary gland(s) may teach researchers about the disorders and their genetics. Objectives: - To study salivary gland diseases and disorders. To collect data and samples from people with salivary gland problems and their relatives. Eligibility: - People more than 4 years old who have or are suspected to have a disease involving salivary glands. - Their relatives more than 4 years old. - Healthy volunteers 18 years or older. Design: - Participants...
The objective is to identify modifiable clinical factors and neurobiological pathways that lead to the development of chronic pain in patients with early rheumatoid arthritis. Participants will undergo quantitative sensory testing, a type of testing that involves assessing response to well-defined, quantifiable painful stimuli, at 0, 3, and 12 months. A subset of participants will also undergo magnetic resonance imaging at 0 and 12 months to assess neuroimaging markers that have previously been shown to be involved in chronic pain.
Data involving orthopaedic conditions and rehabilitation aspects of musculoskeletal and neuromuscular disorders will be collected and stored as part of the normal clinical care of patients seen in the University of Florida (UF) and Shands Orthopaedics and Sports Medicine Institute.
The objectives of the study are to confirm safety and performance of the Zimmer Nexel Total Elbow when used in primary or revision total elbow replacement.
The Evaluation of Clinical Responsiveness Using the Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI), established in 2008, is a one-site database study conducted at the University of Pennsylvania. The database has yielded valuable information and clinical insights into the pathophysiology, disease processes, including psychological responses, treatments and quality of life associated with dermatomyositis. The CDASI database incorporates the Cutaneous Dermatomyositis Disease Area and Severity Index), a validated outcome measure of disease responsiveness in patients, and other assessment tools, surveys and patient information to help validate the clinical course and...
