Efficacy of golimumab for preventing large joint destruction in patients with rheumatoid arthritis as determined by the ARASHI score.

Objectives: The objective of this study is to investigate the inhibitory effect of golimumab on large joint destruction in patients with rheumatoid arthritis.

Methods: We recruited 45 patients with rheumatoid arthritis and evaluated the radiographic severity of large joint destruction using the assessment of rheumatoid arthritis by scoring of large joint destruction and healing in radiographic imaging (ARASHI) score. We evaluated 450 large joints including the elbow, shoulder, hip, knee, and ankle at baseline and 52 weeks after treatment with golimumab.

Analysis of Mitogen-Activated Protein Kinases in Bone and Cartilage of Patients with Rheumatoid Arthritis Treated with Abatacept.

The aim of this study was to analyze the histological changes related to mitogen-activated protein (MAP) kinases in bone and cartilage treated with abatacept for rheumatoid arthritis (RA). A total of 20 patients of bone and cartilage were assessed: 10 abatacept with methotrexate (MTX)-treated RA patients were compared with 10 MTX-treated RA patients (control). The histology of bone and cartilage was observed by staining with hematoxylin and eosin and analyzed immunohistochemically for the expression of tumor necrosis factor-α, interleukin-6, CD4 (T cell), CD68 (macrophage), receptor activator of nuclear kappa-B ligand, osteoprotegerin, osteopontin, CD29 (β-1 integrin), phospho-p38 MAPK (Tyr180/Tyr182), phospho-p44/42 MAPK (extracellular signal-regulated kinase, ERK1/ERK2), and phosphor-c-Jun N-terminal kinase.

Simultaneous Treatment with Subcutaneous Injection of Golimumab and Intra-articular Injection of Triamcinolone Acetonide (K-Method) in Patients with Rheumatoid Arthritis Undergoing Switching of Biologics: Retrospective Case-Control Study.

Background: Tight control of severe rheumatoid arthritis (RA) in patients with high disease activity, even when using biologics, is sometimes difficult using a treat-to-target strategy. Switching from one biologic to another is associated with lower efficacy than that in treatment-naive cases. We developed the K-method that involves simultaneous treatment with golimumab and intra-articular joint injection of triamcinolone acetonide (TA) in patients undergoing switching of biologics.

Biologic-free remission by orthopaedic surgery in non-responder to infliximab for rheumatoid arthritis.

The aim of this study was to investigate remission and biologic-free remission after orthopaedic surgery and related clinical factors in non-responder to infliximab for rheumatoid arthritis (RA). We analyzed 74 patients who were treated with 3 mg/kg infliximab and methotrexate and underwent orthopaedic surgery after non-responder to infliximab with disease activity score (DAS) 28 (CRP) of ≥3.2.

SDF-1 and CXCR4 in synovium are associated with disease activity and bone and joint destruction in patients with rheumatoid arthritis treated with golimumab.

Objectives: The aim of this study was to determine whether the levels of stromal cell-derived factor (SDF)-1 and its receptor C-X-C chemokine receptor 4 (CXCR4) in synovium were correlated with clinical outcome and bone and joint destruction in rheumatoid arthritis (RA) patients being treated with golimumab.

Methods: Synovial tissues were obtained from 15 golimumab-treated patients and were assessed for SDF-1 and CXCR4 using a new immunohistological scoring system (IH score). The IH score was used to assess correlations between synovial SDF-1 or CXCR4 and the disease activity score (DAS28 CRP), Rooney score, tumor necrosis factor alpha, interleukin-6 (IL-6), CD4, CD20, CD68 and the Assessment of RA by Scoring of Large-Joint Destruction and Healing in Radiographic Imaging (ARASHI) score.

Independent factors affecting recovery time after sedation in patients with intellectual disabilities.

Purpose : The purpose of this study was to identify independent factors associated with prolonged recovery time after intravenous sedation for dental treatment in patients with intellectual disabilities. Methods : This study was designed as a prospective cohort study. Participants were patients with intellectual disabilities, for whom sedation for dental treatment was planned in Okayama University Hospital.

Predictive factors related to the efficacy of golimumab in patients with rheumatoid arthritis.

In order to investigate the predictive factors related to clinical efficacy and radiographic progression at 24 weeks by looking at the serum levels of tumor necrosis factor (TNF)-α and interleukin (IL)-6 including baseline characteristics in patients with rheumatoid arthritis (RA) treated with golimumab, serum concentrations of TNF-α and IL-6 were analyzed every 4 weeks up to 24 weeks in 47 patients treated with golimumab. Baseline levels of the Disease Activity Score 28 C-reactive protein (DAS28-CRP) and Simplified Disease Activity Index (SDAI) scores were also assessed. Radiographic progression using the van der Heijde-modified Sharp (vdH-S) score was assessed in 29 patients.

Hemodynamic changes by drug interaction of adrenaline with chlorpromazine.

Adrenaline (epinephrine) is included in dental local anesthesia for the purpose of vasoconstriction. In Japan, adrenaline is contraindicated for use in patients receiving antipsychotic therapy, because the combination of adrenaline and an antipsychotic is considered to cause severe hypotension; however, there is insufficient evidence supporting this claim. The purpose of the present study was to clarify the changes in hemodynamics caused by drug interaction between adrenaline and an antipsychotic and to evaluate the safety of the combined use of adrenaline and an antipsychotic in an animal study.

Chronic orofacial pain in dental patients: retrospective investigation over 12 years.

Orofacial pain is often difficult to diagnose and treat. However, there have been few reports on the clinical observation of dental patients with orofacial pain. We retrospectively investigated the characteristics of 221 dental patients who had suffered from persistent orofacial pain.

Locally injected dexmedetomidine induces vasoconstriction via peripheral α-2A adrenoceptor subtype in guinea pigs.

Background And Objectives: Recent research shows that locally injected dexmedetomidine enhances the local anesthetic potency of lidocaine via the α-2A adrenoceptor subtype in guinea pigs. However, little is known about the effect of locally injected dexmedetomidine on the peripheral vascular response. This study aimed to evaluate the effect of locally injected dexmedetomidine on the peripheral vascular response, measuring skin blood flow in the injected area in guinea pigs.

Postural stability changes during the prism adaptation test in patients with intermittent and constant exotropia.

Purpose: Computerized static stabilometry is a clinical test in neurologic and muscular diseases to assess postural stability or body sway in a quantitative manner. The purpose of this study was to examine whether postural stability would change in the process of the prism adaptation test in patients with intermittent and constant exotropia.

Methods: Postural stability was measured before the prism adaptation test and immediately, 15 minutes, and 60 minutes after the prism adaptation test by computerized static stabilometry in 17 consecutive adult patients with exotropia, including 10 patients with intermittent exotropia and seven with constant exotropia.
