Medical Versus Surgical Approach to Initial Treatment in Septic Arthritis: A Single Spanish Center's 8-Year Experience.

OBJECTIVE: The aim of this study was to compare the functional results of 2 different procedure types, medical or surgical used in treating native joint septic arthritis. METHODS: In this cohort study, we reviewed the clinical registries of patients admitted to a single third-level hospital with the diagnosis of septic arthritis during the period of January 1, 2008, to January 31, 2016. RESULTS: A total of 63 cases of septic arthritis were identified in which the initial approach for 49 patients was medical (arthrocentesis), whereas the initial approach for 14 patients was surgical (arthroscopy or arthrotomy). Of the 49 patients who received initial medical treatment (IMT), 15 patients (30%) later required surgical treatment because of poor progress. The median age of the patients was 60 (SD, 18) years. The group who received IMT were older than those who received initial surgical treatment (median, 64 years [interquartile range {IQR}, 54-76 years], vs. 48 years [IQR, 30-60 years]). There was a larger percentage of male patients in the surgical group (78% vs. 42% [p = 0.018]). Thirty percent of the medical group had been receiving corticosteroid treatment (p = 0.018). Results of complete recovery of joint functionality showed no significant differences after 1 year (68% with MT vs. 67% with ST, p = 0.91). Both groups had similar symptom duration until diagnosis, duration of antibiotic therapy (median, 30 days [IQR, 28-49 days], vs. 29.5 days [IQR, 27-49] days), and mortality rate (3 in the medical group). CONCLUSIONS: The results of the study show that initial surgical treatment in patients with native joint septic arthritis is not superior to IMT. However, half of the patients with shoulder and hip infections treated with IMT eventually required surgical intervention, suggesting that perhaps this should be the preferred initial approach in these cases.

Las recomendaciones se consensuaron mediante metodología basada en grupos nominales. Un grupo de expertos (15 reumatólogos y 3 radiólogos) definió el alcance, usuarios, apartados del documento, posibles recomendaciones, revisiones sistemáticas a realizar (se utilizaron y actualizaron las revisiones de documentos de consenso previos de EULAR), y de la asignación de tareas. Los expertos delimitaron los apartados y redactaron las recomendaciones. El nivel de evidencia y grado de recomendación se realizó utilizando el sistema del Center for Evidence Based Medicine de Oxford. El grado de acuerdo se estableció mediante un Delphi a 2 rondas. Las recomendaciones se votaron según una escala de 1 (total desacuerdo) a 10 (total acuerdo), definiéndose el acuerdo como una puntuación ≥ 7 por al menos el 70% de los participantes. El documento completo fue revisado por los expertos y el proyecto coordinado por un metodólogo experto. Resultados. Se emitieron 20 recomendaciones que cubren: la validez de la US y RM para la detección de actividad y daño estructural, capacidad diagnóstica, predictora (de progresión de daño estructural, de brote de la enfermedad, respuesta al tratamiento, etc.), utilidad en la evaluación y monitorización de estos pacientes que están en tratamiento, y uso de la US como guía (para infiltraciones o biopsias). Conclusiones. Se presentan recomendaciones útiles para el manejo de la US y RM por los clínicos en pacientes con AR (AU)

Objective. To develop evidence-based recommendations on the use of ultrasound (US) and magnetic resonance imaging (MRI) in patients with rheumatoid arthritis (RA). Methods. Recommendations were generated following a nominal group technique. A panel of experts, consisting of 15 rheumatologists and 3 radiologists, was established in the first panel meeting to define the scope and purpose of the consensus document, as well as chapters, potential recommendations and systematic literature reviews (we used and updated those from previous EULAR documents). A first draft of recommendations and text was generated. Then, an electronic Delphi process (2 rounds) was carried out. Recommendations were voted from 1 (total disagreement) to 10 (total agreement). We defined agreement if at least 70% of experts voted ≥7. The level of evidence and grade or recommendation was assessed using the Oxford Centre for Evidence-based Medicine Levels of Evidence. The full text was circulated and reviewed by the panel. The consensus was coordinated by an expert methodologist. Results. A total of 20 recommendations were proposed. They include the validity of US and MRI regarding inflammation and damage detection, diagnosis, prediction (structural damage progression, flare, treatment response, etc.), monitoring and the use of US guided injections/biopsies. Conclusions. These recommendations will help clinicians use US and MRI in RA patients (AU)

Improvement in Diagnosis and Treat-to-Target Management of Hyperuricemia in Gout: Results from the GEMA-2 Transversal Study on Practice.

INTRODUCTION: The objective of the study was to evaluate changes regarding main European League Against Rheumatism (EULAR) recommendations on diagnosis and treatment of gout compared to a previous assessment. METHODS: The GEMA-2 (Gout Evaluation and MAnagement) is a transversal assessment of practice for gout by rheumatologists. Main outcome variables were improvement of the previous GEMA assessment regarding the rate of crystal-proven diagnosis and that reaching therapeutic serum urate target below 6 mg/dl at last visit. Other management variables (prophylaxis, treatment of flares, lifestyle change advice) were also evaluated along with general characteristics. The sample was powered to include at least 483 patients for up to 50% change. RESULTS: Data on management of 506 patients were retrieved from 38 out of 41 rheumatology units that participated in the previous GEMA audit. Crystal-proved diagnosis rate increased from 26% to 32% (31% improvement) and was higher in gout-dedicated practices; ultrasonography contributed to diagnosis in less than 1% of cases. Therapeutic serum urate at last visit improved from 41% to 64% of all patients (66% of patients on urate-lowering medications), in any case over 50% improvement from the previous assessment. The use of any urate-lowering medication available was not prescribed as per label dosing in patients who failed to achieve target serum urate. Clinical inertia to increase doses of either allopurinol or febuxostat was still present in clinical practice. CONCLUSION: Over 50% improvement in targeting therapeutic serum urate has been observed, but clinical inertia is still present. Diagnosis is still mostly clinically based, ultrasonography not being commonly contributive. FUNDING: Menarini España.

Sialodochitis fibrinosa (kussmaul disease) report of 3 cases and literature review.

BACKGROUND: Sialodochitis fibrinosa is a rare disease which is characterized by recurring episodes of pain and swelling of the salivary glands due to the formation of mucofibrinous plugs. Analytic studies ascertain elevated levels of eosinophils and immunoglobulin E (IgE). Imaging studies such as magnetic resonance imaging (MRI) and sialography reveal dilation of the main salivary duct (duct ectasia). Treatment is initially supportive, consisting of compressive massages, and use of antihistamines and/or corticosteroids. MATERIAL AND METHODS: In the following, 3 cases of sialodochitis fibrinosa are presented which were diagnosed in a third level hospital during the period of 2008 and 2016, as well as a literature review of all cases reported to our knowledge. RESULTS: Of the 41 cases found, including the 3 of this article, 66% were women with an average age of 45 years old. However, 75% of reported cases were of Japanese heritage. Involvement of the parotid glands was more frequent than the submandibular glands. In more than half of all cases treatment with compressive massages, antihistamines and/or corticosteroids was effective. CONCLUSION: Clinicians should consider sialodochitis fibrinosa as a diagnostic possibility when presented with cases of recurring parotid and submandibular gland tumescence.

Longitudinal practice patterns of prophylaxis of glucocorticoid-induced osteoporosis in patients with polymyalgia rheumatica.

The aim of this study was to analyze the longitudinal practice patterns of prophylaxis of glucocorticoid-induced osteoporosis in patients with polymyalgia rheumatica (PMR). Patients diagnosed with PMR were collected retrospectively in two rheumatology departments. In addition to demographic and diagnostic criteria, the chart review included the following information at baseline and at follow-up: doses of prednisone, prescription of calcium, vitamin D and bisphosphonates, bone mass measurement (BMD) and fragility fractures. We analyzed the percentage of patients undergoing BMD and were prescribed a bisphosphonate over the years. We evaluated 158 patients: 117 of them were women, mean age was 73 years, and they had an average follow-up of 4.8 years. 104 patients (66 %) received osteoporosis medication during the first visit, 44 of them were given bisphosphonate. During follow-up, another 30 treatments with bisphosphonate were added (46 % overall) while 37 cases (23 %) received no treatment with calcium or bisphosphonate. BMD was performed in 111 patients (69 %; 53 % of males and 76 % of females). Factors associated with the use of bisphosphonates were female sex (OR 4.4, 95 % CI 4.02-4.86), BMD (OR 2.4, 95 % CI 2.05-2.78) and commencement of treatment after the year 2005 (54 vs 37 %, OR 1.93, 95 % CI 1.60-2.26). No significant differences were found with age, initial doses of prednisone or the hospital. According to recent prevention guidelines, treatment with biphosphonate should have been administered in more than 90 % of patients. Although prophylaxis of glucocorticoid-induced osteoporosis in patients with PMR has increased in the recent years, many patients do not receive prophylaxis with bisphosphonate during the first visit.

Ultrasound-detected musculoskeletal urate crystal deposition: which joints and what findings should be assessed for diagnosing gout?

OBJECTIVE: The primary objective of this prospective case-control study was to assess the diagnostic value of several intra-articular and periarticular ultrasound (US)-detected abnormalities in the upper and lower limbs in gout. The secondary objective was to test the concurrent validity of US abnormalities using as gold standard the microscopic demonstration of monosodium urate (MSU) crystals. METHODS: Ninety-one men with gout and 42 age-matched controls were prospectively recruited. All patients with gout and controls underwent US assessment of several US abnormalities in 26 joints, six bursae, eight tendons, 20 tendon compartments, four ligaments, and 18 articular cartilages by experts in US blinded to the patients' group. Patients with gout and controls with US abnormalities were asked to undergo US-guided aspiration for microscopic identification of MSU crystals. Interobserver and intraobserver reliability of the US assessment was evaluated in a web-based exercise. RESULTS: The assessment of one joint (ie, radiocarpal joint) for hyperechoic aggregates (HAGs), two tendons (ie, patellar tendon and triceps tendon) for HAGs and three articular cartilages (ie, first metatarsal, talar and second metacarpal/femoral) for double contour sign showed the best balance between sensitivity and specificity (84.6% and 83.3%, respectively). Intraobserver reliability was good (mean κ 0.75) and interobserver reliability was moderate (κ 0.52). The aspirated material from HAGs was positive for MSU crystals in 77.6% of patients with gout and negative in all controls. CONCLUSIONS: Our results suggest that US bilateral assessment of one joint, three articular cartilages and two tendons may be valid for diagnosing gout with acceptable sensitivity and specificity.

[Antimalarials: an update in rheumatic diseases]. / Antipalúdicos: actualización de su uso en enfermedades reumáticas.

Antimalarials are long-standing drugs that have been used since the nineteenth century for the treatment of skin rashes and lesions in lupus and rheumatoid arthritis. In recent decades, their use in these disorders has been consolidated, and new mechanisms of action have been incorporated, broadening the therapeutic perspectives of these drugs. Antimalarials are the treatment of choice in mild and moderate manifestations of systemic lupus erythematosus and are established as part of combined therapy in rheumatoid arthritis. They have been shown to have beneficial effects on atherosclerosis, as well as a possible role in the early treatment of antiphospholipid syndrome. Lastly, they have been shown to have a potential use in other rheumatic diseases such as Sjögren's Syndrome and palindromic rheumatism. This review aims to provide an update on the use of these drugs in rheumatology and to discuss their toxicity profile.

Nodulosis acelerada por metotrexato en un paciente con artritisreumatoide y síndrome de Sjögren / Methotrexate-induced accelerated nodulosis in a patient with rheumatoid arthritis and Sjögren´s syndrome

La nodulosis acelerada por metotrexato se describió inicialmente en pacientes con artritis reumatoide que recibían tratamiento con este fármaco. Se caracteriza por la aparición brusca de nódulos reumatoides y/o aumento de los preexistentes, coexistiendo con un buen control analítico y clínico de la enfermedad articular. La retirada del fármaco induce la regresión total o parcial de los nódulos y su reintroducción a nuevas recidivas. Presentamos a un varón de 70 años con artritis reumatoide erosiva de más de 25 años de evolución, con factor reumatoide positivo, autoanticuerpos y síndrome de Sjögren secundario. Desde hacía unos años presentaba dos nódulos subcutáneos en la superficie cubital de ambos antebrazos. Por una intensa reagudización de la sintomatología articular se instauró tratamiento con metotrexato (7,5 mg/semanales), con una excelente respuesta clinicoanalítica. Cuatro años después, todavía en tratamiento con metotrexato, presentó nuevos nódulos en ambas manos y un aumento llamativo de los preexistentes, que no se acompañaban de un empeoramiento de la artritis ni de alteraciones analíticas. Ante la sospecha de una nodulosis acelerada por metotrexato éste se suspendió, con lo que remitieron totalmente los nódulos de más reciente aparición y disminuyeron de tamaño los preexistentes. Nueve meses más tarde, por reagudización de la artritis, se reintrodujo el metotrexato lo que motivó un nuevo episodio de nodulosis, que mejoró al suspender definitivamente la administración del fármaco.
