Intra-articular Treatment of Digital Osteoarthritis by Radiosynoviorthesis-Clinical Outcome in Long-term Follow-up.

Purpose: This retrospective study analyzed the long-term effects of radiosynoviorthesis (RSO) with special emphasis to local joint pain in patients from 4 different RSO centers in Germany and Austria.

Methods: A total of 168 finger joints in 147 patients with digital joint OA were investigated. The indication for RSO was based on both clinical complaints and a proven synovitis, despite anti-inflammatory pharmacotherapy and previous intra-articular corticosteroid injections.

The EANM guideline for radiosynoviorthesis.

Purpose: Radiosynoviorthesis (RSO) using the intraarticular application of beta-particle emitting radiocolloids has for decades been used for the local treatment of inflammatory joint diseases. The injected radiopharmaceuticals are phagocytized by the superficial macrophages of the synovial membrane, resulting in sclerosis and fibrosis of the formerly inflamed tissue, finally leading to reduced joint effusion and alleviation of joint pain.

Methods: The European Association of Nuclear Medicine (EANM) has written and approved these guidelines in tight collaboration with an international team of clinical experts, including rheumatologists.

[Joint DGN, OGNMB and SGNM S1 guideline for radiosynoviorthesis].

This recommendation is intended to provide a guideline for radiosynoviorthesis (RSO) in the effective local treatment of chronic inflammatory (non-infectious) joint diseases. It was developed in an interdisciplinary manner and describes the general objectives, definitions, clinical background information, indication and contraindications of this radionuclide therapy. The requirements to be met by a treatment center, the results of pretherapeutic examinations as well as recommendations on how the treatment should be carried out.

Fine-Needle Aspiration with Immunohistochemistry Using a Modified Scrape Cell Block Technique for the Diagnosis of Thyroid and Parathyroid Nodules.

Objective: To evaluate the diagnostic accuracy of a modified scrape cell block (SCB) technique in a large series of patients. The technique was especially developed and tested for fine-needle aspiration of thyroid and parathyroid nodules.

Study Design: Eighty-two ultrasound-guided fine-needle aspiration specimens with the sonographic aspect of a thyroid (n = 33) or a possible parathyroid nodule (n = 49) were studied.
