Pediatric Vasculitis Initiative
Childhood chronic vasculitis describes a group of rare life-threatening diseases that have in common inflammation of blood vessels in vital organs such as kidneys, lungs and brain. Most knowledge about them comes from adult patients. Severe disease requires aggressive life-saving treatments with steroids and some cancer drugs which can themselves cause damage, and increase risks of cancer and severe infections. Conversely, milder disease can be treated with less toxic drugs. Different classification and "scoring tools" are used to define the types and severity of vasculitis and to measure damage caused by disease or drugs. These in turn help direct how aggressively to treat...

Perform Humeral System Study
This study is an international, single arm, multicenter, prospective, non-significant risk, Post-Market Clinical Follow-up study, which is designed to collect safety and performance data at baseline, surgery, immediate post-op and annually through 10 years post-operation. Data collected from this study will be used for purposes, including but not limited to, Post-Market Surveillance, peer-reviewed publications, education materials, regulatory submissions, and/or product development.

Perfusion MRI-targeted Joint Embolization for Chronic Musculoskeletal Pain of the Shoulder, Hip and Knee
In this work the investigators will study the relationship between chronic musculoskeletal pain and abnormal blood flow (neovascularity) around the shoulder, hip and knee. Veterans with as history of chronic shoulder, hip or knee pain and mild/moderate joint degenerative changes will be potential study subjects. Blood flow around joints will be evaluated using perfusion magnetic resonance imaging (MRI). Participants with demonstrably abnormal blood flow around their painful joint will be eligible for enrollment in a pilot study of joint embolization to treat their pain. Participants who choose to not undergo treatment will be re-assessed with MRI after one year to characterize the...

Periacetabular Osteotomy With and Without Arthroscopic Management of Central Compartment Pathology
At present, it is not clear whether performing a hip arthroscopy at the same time as a PAO improves patient outcomes after surgery compared to a PAO alone. This research project will randomize patients to receive either a PAO alone, or a PAO and a hip arthroscopy at the same time.

Perioperative Steroid Dosing on the APR in AIS
The objective of this study is to perform a prospective, randomized controlled trial investigating the clinical usage of perioperative dexamethasone usage on APR activation, postoperative morphine usage, postoperative nausea, and hospital length of stay. There will be a control control and a Dexamethasone cohort. Participants will be randomized into one of the two cohorts. Patients in the control group will receive one 8mg dose of dexamethasone intraoperatively as per standard of care anesthesia protocols. Patients randomized to the dexamethasone cohort will be administered 8 mg of dexamethasone with 3 additional doses administered at 8-hour intervals following surgery for a...

Personalized Spine Study Group (PSSG) Registry
The primary objective of the study is a data collection initiative. The study will collect clinical and radiographic outcomes of patients implanted with patient specific rods. The secondary objective is to collect clinical and radiographic outcomes of patients with hardware as a control cohort to the patient-specific rods.

Persona OsseoTi Keel Compatibility Study (Total Knee Arthroplasty)
The main objective of the study is to evaluate the safety, performance and clinical benefits of the Persona implant and its instrumentation in primary total knee arthroplasty
-
Persona Revision Knee System Outcomes
The study will evaluate the performance, clinical benefits and safety of the Persona Revision Knee System in patients who have received primary or revision total knee arthroplasty (TKA) treatment. This will be done using a multicenter, single-arm, consecutive series, retrospective cohort study with prospective follow-up.

Pharmacokinetics, Pharmacodynamics, and Safety Profile of Understudied Drugs Administered to Children Per Standard of Care (POPS)
The study investigators are interested in learning more about how drugs, that are given to children by their health care provider, act in the bodies of children and young adults in hopes to find the most safe and effective dose for children. The primary objective of this study is to evaluate the PK of understudied drugs currently being administered to children per SOC as prescribed by their treating provider.
