Arthroscopic Labral Repair Versus Physical Therapy for Tears of the Acetabular Labrum
Tears of the acetabular labrum appear to be common with the prevalence of asymptomatic tears in the general population approaching 66% and 70% based on cadaveric dissection and magnetic resonance imaging, respectively. Despite this prevalence, there is no currently accepted justification for performing labral repair in an asymptomatic patient despite the many postulated biomechanical benefits that an intact labrum imparts to the hip joint. Representing a smaller proportion of all tears, symptomatic tears of the acetabular labrum present a therapeutic challenge. Current treatment modalities range from conservative measures to open surgical...

Articulating Versus Static Antibiotic Loaded Spacers for the Treatment of Prosthetic Knee Infection
Infection remains a difficult-to-treat complication of total knee arthroplasty. The gold standard treatment is two-stage removal of the prosthesis with later replacement of permanent implants. The first stage consists of removal of the infected arthroplasty components and the surrounding devitalized tissue, copious pulsed irrigation, and placement of a temporary antibiotic-impregnated cement spacer. This spacer typically is left in place six weeks, during which time the patient receives intravenous antibiotics. After the surgeon feels that the infection has been eradicated, or if the patient requires repeat debridement, a second operative...

A Safety, Efficacy And Pharmacokinetics Study Of Tofacitinib In Pediatric Patients With sJIA
A randomized withdrawal study in which responders to open-label treatment with tofacitinib will be randomized in a 1:1 ratio to tofacitinib or placebo in a double-blind phase. In the double-blind phase "time to sJIA flare" will be evaluated as primary endpoint and subjects will be discontinued once they experience sJIA flare. Once 31 flares are reported the study will be completed.

Assess Efficacy of of Oral Treprostinil in Patients With Symptomatic Primary or Secondary Raynaud's Phenomenon
This study represents the first trial to assess the efficacy of oral treprostinil therapy in patients with symptomatic primary or secondary Raynaud's Phenomenon (RP) resistant to vasodilatory therapy. The study will be randomized 1:1 UT-15C to placebo. The design is a crossover study and all subjects will be randomized to receive oral treprostinil sustained release tablets or matching placebo for 12 weeks and then crossover for 12 weeks. All subjects will be exposed for 12 weeks of treatment with oral UT-15C during the study.

Assessing a New Jaw Support Device During Third Molar Extractions
During mandibular 3rd molar (wisdom tooth) extractions, when a downward force is placed on the patient's jaw, the patient must tense his/her jaw muscles to oppose it. Patients under moderate/deep sedation or general anesthesia cannot tense their muscles to counter this downward force to prevent injury to the jaw including the temporomandibular joint (TMJ). Bite blocks hold the patient's mouth open but do not counter this downward force on the mandible. Currently, oral and maxillofacial surgeons (OMSs) when surgically removing 3rd molars (wisdom teeth) with moderate/deep sedation or general anesthesia have a dental assistant that stands ...

Assessment of Neuroinflammation in Central Inflammatory Disorders Using [F-18]DPA-714.
The primary objective of this study is to measure the concentration and the regional brain distribution of activated brain microglia/macrophages using the PET radiopharmaceutical [F-18]DPA-714 in individuals with chronic pain and fatigue suspected to be associated with neuroinflammation. The PET tracer [F-18]DPA-714 binds to the 18 kDa translocator protein (TSPO, also known as the peripheral benzodiazepine receptor) in the mitochondria of activated microglia/macrophages and provides a non-invasive measure of neuroinflammation. The primary objective of this study is to determine if pain and fatigue patients have higher levels of ...

Assessment of Small Fiber Neuropathy in Rare Diseases Using Sudoscan
Sudoscan™ (Impeto Medical, Paris France) uses electrochemical skin conductance as a novel noninvasive method to detect sudomotor dysfunction. Several small studies have recently shown that Sudoscan use in the assessment of small fiber polyneuropathy (in diabetes mellitus) can be performed non-invasively, quickly and effectively. The investigators aim to study the use of Sudoscan in rare disease condition associated with small fiber polyneuropathy.
