Development of a guideline for the use of ultrasonography in rheumatoid arthritis: Preliminary recommendations.

AIM: To address the protocol of recommendations for the use of ultrasonography (US) in the management of rheumatoid arthritis (RA) in routine practice. METHODS: The present study is a protocol design for practical guidelines. Based on a systematic literature review, the scientific committee (composed of 6 experts on US) decided on key questions which will be used to develop recommendations. These recommendations will be submitted to a group of experts in US in rheumatic and musculoskeletal diseases using the Delphi method. This step will lead to preliminary recommendations. The next step will be to submit the preliminary guideline to an expanded group of US experts to check their relevance. The level of agreement of the experts will be recorded during a web-based meeting. RESULTS: Following two rounds of the Delphi method, a consensus will be addressed. The latter will i) Highlight the use of US for the diagnosis of RA in an early stage of the disease; ii) Define the role of US during follow-up; and iii) Underline the importance of US for the management of clinical remission. CONCLUSION: These recommendations will harmonize and optimize clinical practice and management of RA patients.

Ultrasonography of Shoulder in Rheumatoid Arthritis: A Reliability Exercise Using Consensual Definitions among Maghrebian Rheumatologists.

The shoulder may be affected in a large portion of patients with rheumatoid arthritis (RA) worldwide. However, this joint does not receive the attention required during follow-up. Indeed, although numerous clinical tests for diagnosis of a painful shoulder are available, differentiating articular from peri-articular lesions may be difficult in daily practice. Fortunately, the precise diagnosis of shoulder pain in RA has benefited from a reliable imaging modality used to detect its exact origin-ultrasonography (US). This study was aimed at assessing the intra- and inter-observer reliability of ultrasonographic findings for patients with established RA with shoulder pain in a patient-based exercise as a clinical challenge among Maghrebian rheumatologist experts in US. A total of 7 operators examined 10 patients in two rounds independently and blindly of each other. Before beginning the session, all of the rheumatologists reached a consensus on sites and US settings by performing a brief exercise on a normal shoulder. Outcome Measures in Rheumatology Clinical Trials (OMERACT) definitions of US-detected pathologies were used. Each patient underwent US scanning of the painful shoulder in predefined sites based on US technical guidelines of the European Society of Musculoskeletal Radiology: long head of biceps (LHB), subscapularis recess, posterior recess and axillary recess. The presence of subdeltoid or subcoracoid bursitis or full rupture of the suprasupinatus was identified if present. Intra- and inter-observer reliability measures were calculated using the κ coefficient. Intra-observer reliability was good for gray-scale (GS) synovitis in subscapularis and posterior recesses (κ = 0.77 and 0.73, respectively). It was moderate in the presence of GS synovitis and effusion in LHB (κ =0.53 and 0.40, respectively), posterior and subscapularis recess effusion (κ = 0.56 and 0.60, respectively) and GS and power Doppler (PD) synovitis in axillary recesses (κ = 0.58 and 0.49, respectively). Inter-observer reliability was good for PD for LHB signals (κ = 0.78). It was moderate for GS for LHB synovitis (κ = 0.54). Inter-observer agreement was poor for effusion and GS synovitis for subscapularis, posterior and axillary recesses, and very poor for PD signals in these recesses. US was a reliable imaging tool for detecting tenosynovitis in the LHB. However, reliability was moderate to poor in detecting synovitis in subscapularis, posterior and axillary recesses. These findings could be optimized by standardization of sites to assess.

A Rare Case of Hypophosphataemic Osteomalacia in von Recklinghausen Neurofibromatosis.

BACKGROUND: Neurofibromatosis type 1 (NF1), also known as von Recklinghausen disease, is a one of the more common hereditary autosomal disorders. However, osteomalacia in neurofibromatosis type 1 is very rare tumour-induced osteomalacia; fibroblast growth factor-23 is usually implicated. PATIENTS AND METHODS: We report the case of a patient with a history of von Recklinghausen neurofibromatosis who presented with hypophosphataemic osteomalacia. RESULTS: The patient was treated with high-dose calcitriol and oral phosphate with clinical improvement. CONCLUSION: Even though it is a rare entity, we must consider the diagnosis of hypophosphataemic osteomalacia in patients with neurofibromatosis in order to deliver appropriate treatment. LEARNING POINTS: Osteomalacia during von Recklinghausen disease is a rare presentation of an uncommon condition and has a poorly understood mechanism.The treatment of oncogenic osteomalacia includes tumour removal which, however, is not always possible.Administration of calcitriol alone is not sufficient and phosphorus intake is mandatory to improve symptoms.

Multifocal tuberculosis on certolizumab pegol in a patient followed for rheumatoid arthritis.

Tuberculosis must be considered in front of deterioration in general condition in patient with rheumatic disease under biological therapy. Rheumatologists may pay attention and screen infections before and after prescribing biological therapy.

[Monoarthritis of the elbow revealing an intraarticular osteoid osteoma]. / Monoarthrite du coude révélatrice d'un ostéome ostéoïde intra-articulaire.

BACKGROUND: Osteoid osteoma is one of the unusual causes of musculoskeletal pain. Its diagnosis is usually not difficult in classic diaphyseal localization. However, the diagnosis of juxta or intraarticular osteoid osteoma is challenging because of atypical clinical presentation responsible for long diagnosis delay. AIM: Report a new case. CASE REPORT: We report herein the case of a 22-year-old woman presenting an intraarticular osteoid osteoma of the elbow. Diagnosis has been established on imaging findings (MRI and CT-scan) after 10 months because of atypical clinical presentation as a chronic monoarthritis of the elbow. The picture of an osteoid osteoma of the lower extremity of the humerus associated to a synovitis and a joint effusion was suspected on MRI. It had been confirmed on CT-scan wich showed the nidus. Surgical removal of the tumor allowed pain relief and functional restoration in postoperatively. CONCLUSION: Regarding an unexplained chronic monoarthritis, the diagnosis of intraarticular osteoid osteoma should be evoked. CT-can remains the investigation of choice for identifying the nidus. Surgical exicision permits the relief of symptoms.

Hemarthrosis revealing congenital factor XI deficiency.

Congenital factor XI deficiency (also known as the Rosenthal syndrome or hemophilia C) manifests as minor bleeding, usually after trauma or surgery. We report a case in which bilateral knee hemarthrosis was the first manifestation. The patient presented at 32 years of age with a 2-year history of mechanical pain and intermittent swelling in both knees. Knee aspiration recovered blood-tinged fluid. The laboratory workup showed severe factor XI deficiency. Replacement therapy with fresh frozen plasma was effective. Tests in the family showed factor XI deficiency in the patient's sister.

[The synoviorthesis: a reappraisal]. / Les synoviortheses: etat des lieux.

BACKGROUND: The evolution of the rheumatologic practice involved a handing-over in question of the place and methods of application of the synoviorthesis. The last innovations, in particular the appearance of the bio-therapies, allowed a better control of inflammatory rheumatism thus making it possible to better select arthritis likely to profit precociously from a synoviorthesis before the installation of major articular destruction. AIM: Through a general review of the literature, we recall in this work the various means of synoviorthesis, their current indications and their results. METHODS: An extensive electronic search of the relevant literature was carried out using MEDLINE. Key words used for the final search were: synoviorthesis, osmic acid, radiosynoviorthesis, arthritis, treatment. RESULTS: This systematic review allowed us to conclude that fields of application of the synoviorthesis is in addition widens because of the interesting results to see spectacular this technique in some other affections such as the haemophilia. In addition we have compared the efficiency and the tolerance of the different methods of synoviorthesis. CONCLUSION: The synoviorthesis constitutes a tempting therapeutic alternative of share its effectiveness and its good tolerance so much so that it constitutes an undeniable factor of articular protection. Its fields of application widened. Thus on the good knowledge of the indications and the precautions necessary to its realization its success.

Cerebral vasculitis in a patient with rheumatoid arthritis.

Inflammatory vasculitis of the central nervous system is exceedingly rare in patients with rheumatoid arthritis (RA). The symptoms may be misleading. Most of the reported cases occurred in males with long-standing, nodular, destructive, rheumatoid factor-positive disease. Severe constitutional symptoms and prominent extraarticular manifestations of vasculitis were usually present. We report a case of cerebral vasculitis in a 59-year-old woman with a 20-year history of destructive rheumatoid factor-positive RA that was well controlled by methotrexate. Headache that was unresponsive to symptomatic treatment developed abruptly, together with gait disorders. Magnetic resonance imaging of the brain showed dot-like areas of high-signal in a periventricular subcortical distribution on both sides. Magnetic resonance angiography visualized a long tight stenosis of the right internal carotid artery and a string-of-beads stenosis of the left internal carotid artery suggesting vasculitis. Pulse therapy with methylprednisolone (1 g/d for 3 days) and cyclophosphamide (1 g) once a month ensured resolution of the neurological symptoms and laboratory evidence of inflammation. There was no evidence of a relapse at last follow-up after 5 months. Cerebral vasculitis is usually treated with monthly glucocorticoid and cyclophosphamide boluses separated by continuous glucocorticoid therapy. TNFalpha antagonists may be effective in patients who fail to respond to conventional treatment. However, other vasculitides such as giant cell arteritis and Wegener's granulomatosis must be ruled out, as they are refractory to TNFalpha antagonist therapy.

[Treatment of gout in 2006]. / Traitement de la goutte en 2006.

Gout is one of the oldest and better understood among rheumatic diseases. It is characterized by chronic hyperuricemia and recurrent attacks of acute arthritis provoked by release of sodium urate crystals into joints. The manifestations of Gout can be abolished by lifelong urate-lowering therapy maintainine serum urate levels under 360 mmol/l. The management of a minority of patients, including those with renal impairment, is difficult and often unsatisfactory because of restricted treatment options. In this paper; the current options for treating hyperuricemia are first discussed then followed by new approches.
