Manipulation under anesthesia (MUA) can help patients regain an adequate range of motion (ROM) following total knee arthroplasty (TKA). Although there are studies reporting that MUA can assist in improving ROM, there is a paucity of studies regarding whether requiring an MUA is associated with an increased risk of revision. The purpose of this study was to assess the: (1) incidence of revision TKA and (2) outcomes of those undergoing MUA and compare it with a matched cohort who did not require MUA. A prospectively collected database of two high-volume institutions was assessed for patients who required a single MUA following TKA between 2005 and 2011...

BACKGROUND: Leflunomide is a low-molecular-weight compound that is widely used in the treatment of rheumatoid arthritis. Although leflunomide is thought to act through the inhibition of the de novo pyrimidine synthesis, the molecular mechanism of the drug remains largely unknown. We investigated the antiarthritis effects and mechanisms of action of the active metabolite of leflunomide, A77 1726, in interleukin-1 receptor antagonist-knockout (IL-1Ra-KO) mice. METHODS: 14- to 15-week-old male IL-1Ra-KO mice were treated with 10 or 30 mg/kg A77 1726 via intraperitoneal injection three times per week for 6 weeks...

OBJECTIVES: Graves' ophthalmopathy occurs in 50% of Graves' disease cases. Treatment is based on smoking cessation, and control of the euthyroidism and ocular repercussions associated with the disease. The active orbital forms are treated with glucocorticoids. Non-validated therapies have also been recently tested. Rituximab has been effectively used several times to treat corticosteroid-resistant Graves' ophthalmopathy associated with an optic neuropathy, but its use could be proposed only in inflammatory ophthalmopathies after failure of the corticosteroids...

Previous functional magnetic resonance imaging (fMRI) findings indicate that shoulder apprehension is more complex than a pure mechanical problem of the shoulder, showing a direct modification in functional brain networks associated with motor inhibition and emotional regulation. The current study extends these findings by investigating further structural alterations in patients with shoulder apprehension compared to controls. 14 aged patients with shoulder apprehension (27.3 ± 2.0 years) and 10 matched healthy controls (29...

BACKGROUND: Most surgeons advocate in situ fixation of the slipped epiphysis with acceptance of any persistent deformity in the proximal femur [Aronsson DD, Loder RT, Breur GJ, Weinstein SL (2006) Slipped capital femoral epiphysis: current concepts. J Am Acad Orthop Surg 14, 666-679]. This residual deformity can lead to osteoarthritis due to femoroacetabular cam impingement (FAI) [Leunig M, Slongo T, Ganz R (2008) Subcapital realignment in slipped capital femoral epiphysis: surgical hip dislocation and trimming of the stable trochanter to protect the perfusion of the epiphysis...

Sonic hedgehog (Shh) is a morphogen essential to the developing nervous system that continues to play an important role in adult life by contributing to cell proliferation and differentiation, maintaining blood-brain barrier integrity, and being cytoprotective against oxidative and excitotoxic stress, all features of importance in amyotrophic lateral sclerosis (ALS). ALS is a fatal disease characterized by selective loss of motor neurons due to poorly understood mechanisms. Evidence indicates that Shh might play an important role in ALS, and that Shh signaling might be also adversely affected in ALS...

OBJECTIVE: To carry out a double-blind RCT to compare the effectiveness of topical tacrolimus (TAC), triamcinolone acetonide (TRI) and placebo (PLA) in symptomatic OLP. SUBJECTS AND METHODS: A clinical score (CS, range 0-130) was developed to measure the clinical signs and symptoms of OLP. Twenty-seven OLP patients with a CS of ≥ 20 were randomly allocated to receive 0.1% TAC ointment (n=11), 0.1% TRI paste (n=7) or Orabase(®) paste as PLA (n=9) for 3 weeks. If the CS dropped ≥ 20% (interpreted as response), the patients continued the same medication for another 3 weeks...
