Abstract We investigated the effects of ibandronate, a bisphosphonate; eldecalcitol, an active vitamin D3 analogue; and combination treatment with both agents on secondary osteoporosis and arthritis using rats with adjuvant-induced arthritis. Arthritis was induced in 8-week-old male Lewis rats. Rats were randomized into four treatment groups and an untreated normal control group: ibandronate, eldecalcitol, ibandronate + eldecalcitol, vehicle, and control. Paw thickness was measured to evaluate arthritis. Joint destruction was evaluated histomorphometrically by the ankle joint stained with Fast Green and safranin O...

Abstract Objective: Recent studies have provided new insights into the role of lymph nodes (LNs) in rheumatoid arthritis (RA). The aim of this study was to evaluate the metabolic activity of the axillary LNs in relation to that of the upper limb joints and the clinical assessment of disease activity in RA patients treated with biologic therapies. Method: 18F-fluorodeoxyglucose-positron emission tomography/computed tomography (18F-FDG-PET/CT) scans were acquired for 64 patients with RA at baseline and after 6 months of biologic therapy, and the patients' clinical status was evaluated. The maximum standardized ...

Tal, Berg / Boaz, FrenkelPage 816 - 820Preauricular swelling followed by limited mouth opening can be a challenging diagnosis. All anatomical structures and related pathologies should be examined. A 41-year-old woman presented to the Emergency Room complaining of limited mouth opening, severe pain that was worse on chewing, and swelling over her right temporomandibular joint (TMJ) that had started 3 days previously. Physical examination revealed localized swelling and redness over her right TMJ. Her right masticatory muscles were very painful and tender on palpation. Mouth opening was slightly limited. A computed tomograph...

ConclusionsPDB is often diagnosed through incidental findings in a regular blood chemistry panel, particularly ALK, or through imaging done for another reason. The planar radiograph gives the best clue to the presence of PDB. The MDCT is mandatory for better outcomes in treatment of osteosarcoma, whereas MRI is best for depicting local intracranial extension. PET identifies the region of a tumor through FDG increase. Lastly, biopsy is necessary for confirming the tumor.

ObjectiveTo examine whether allopurinol dose escalation to achieve serum urate (SU) target can influence bone erosion or monosodium urate (MSU) crystal deposition, as measured by dual ‐energy computed tomography (DECT) in patients with gout.MethodsWe conducted an imaging study of a 2 ‐year randomized clinical trial that compared immediate allopurinol dose escalation to SU target with conventional dosing for 1 year followed by dose escalation to target, in gout patients who were receiving allopurinol and who had an SU level of ≥0.36 mmoles/liter. DECT scans of feet and radiog raphs of hands and feet were obtained at ...

ConclusionActive articular RA was associated with an increased risk of developing RA ‐ILD. These results suggest that decreasing systemic inflammation may alter the natural history of RA‐ILD development.

Conclusions: This cadaveric study aids in establishing the prevalence of LSTV (12.7%) in a random population and the frequency of the various Castellvi LSTV morphologies. An association was found between type Ia morphology and L4–L5 osteoarthritis which has not been reported in the past, suggesting that mild LSTV may carry more significance to lumbar pathology than previously considered.

ABSTRACTIn rheumatoid arthritis (RA), chronic joint inflammation leading to bone and cartilage damage is the major cause of functional impairment. Whereas reduction of synovitis and blockade of joint damage can be successfully achieved by disease modifying antirheumatic therapies, bonerepair upon therapeutic interventions has only been rarely reported. The aim of this study was to use fluorodeoxyglucose ([18F]FDG) and [18F]fluoride µPET/CT imaging to monitor systemic inflammatory and destructive bone remodeling processes as well as potential bone repair in an established mouse model of chronic inflammatory, erosive p...

AbstractObjectiveFew studies have systematically and quantitatively addressed the impact of urate ‐lowering therapy on monosodium urate (MSU) deposition. Herein, we analyzed the effect of lifestyle measures and conventional uric acid lowering therapy on MSU deposits in gout patients.MethodsIn this prospective study, subjects with a diagnosis of gout according to ACR/EULAR classification criteria and presence of MSU deposits in dual energy computed tomography (DECT) scans received either lifestyle intervention or conventional urate ‐lowering therapy for a mean period of 18 months before follow‐up DECT scan. Detected M...
