Ultrasonografía musculoesquelética: su utilidad en osteoartritis y artropatías microcristalinas
Entre los principales motivos de consulta al reumatólogo se encuentran entidades tales como la osteoartritis (OA) y las artropatías microcristalinas. Tradicionalmente, la OA ha sido estudiada y clasificada mediante la radiografía convencional. Esta técnica, sin embargo, no demostró ser útil para valorar la evolución de la enfermedad. Asimismo, existe el concepto de OA pre-radiológica, situación en la que existen lesión cartilaginosa y modificaciones en el hueso subcondral que no pueden, por su precocidad, ser detectadas por radiología convencional..
Tumor del cuerpo carotídeo: Presentación de un caso por ecografía y resonancia magnética Carotid body tumor: A case presentation with ultrasonography and magnetic resonance imaging
El tumor de cuerpo carotídeo, que se origina en los quimiorreceptores de dicha estructura, representa hasta el 50% de los paragangliomas de cabeza y cuello. En forma frecuente, constituye un hallazgo incidental (asintomático), aunque en algunos casos los pacientes pueden consultar por una masa indolora, ronquera, paresia lingual y/o disfagia. Sus características imagenológicas permiten una aproximación diagnóstica no invasiva con altos índices de sensibilidad y especificidad, por lo que su conocimiento facilita la conducta clínico-terapéutica. Se presenta un caso clínico que resulta particularmente elocuente para la práctica diaria, ya que la paciente tiene antecedentes quirúrgicos por patología tiroidea maligna, hecho que precisa una aproximación diagnóstica estricta para su correcto seguimiento.The carotid body tumor, which arises from its chief cells (glomus type 1), is the most common paraganglioma of the head and neck (up to 50%). This tumor is in most cases clinically silent and is detected incidentally at imaging study during evaluation of patients with unrelated symptoms such as painless, slowly growing lateral neck mass, dysphagia, sleep apnea, and paresia or atrophy of the tongue. According to its appearance, precise non-invasive imaging techniques may allow the radiologist to reach the correct diagnosis and treatment. The following case report is particularly useful for daily practice; the patient has surgical history of tiroid neoplasm which requires a thorough diagnosis, in order to determine an accurate follow-up
How is the ultrasound in rheumatology used, implemented, and applied in Latin American centers? Results from a multicenter study
This study aimed to perform an overview of how ultrasound (US) is being used, implemented, and applied in rheumatologic centers in Latin America (LA). A retrospective, multicenter 1-year experience study was undertaken. Eighteen centers from eight countries were involved. The following information were collected: demographic data, indication to perform an US examination, physician that required the examination, and the anatomical region required for the examination. A total of 7167 patients underwent an US examination. The request for US examinations came most frequently from their own institution (5981 (83.45 %)) than from external referral (1186 (16.55 %)). The services that more frequently requested an US examination were rheumatology 5154 (71.91 %), followed by orthopedic 1016 (14.18 %), and rehabilitation 375 (5.23 %). The most frequently scanned area was the shoulder in 1908 cases (26.62 %), followed by hand 1754 (24.47 %), knee 1518 (21.18 %), ankle 574 (8.01 %), and wrist 394 (5.50 %). Osteoarthritis was the most common disease assessed (2279 patients (31.8 %)), followed by rheumatoid arthritis (2125 patients (29.65 %)), psoriatic arthritis (869 patients (12.1 %)), painful shoulder syndrome (545 (7.6 %)), connective tissue disorders (systemic sclerosis 339 (4.7 %), polymyositis/dermatomyositis 107 (1.4 %), Sjögren’s syndrome 60 (0.8 %), and systemic lupus erythematosus 57 (0.8 %)). US evaluation was more frequently requested for diagnostic purposes (3981 (55.5 %)) compared to follow-up studies (2649 (36.9 %)), research protocols (339 (4.73 %)), and invasive guided procedures (198 (2.76 %)). US registered increasing applications in rheumatology and highlighted its positive impact in daily clinical practice. US increases the accuracy of the musculoskeletal clinical examination, influence the diagnosis, and the disease management. © 2016, International League of Associations for Rheumatology (ILAR)

An international SUrvey on non-iNvaSive tecHniques to assess the mIcrocirculation in patients with RayNaud'\u80\u99s phEnomenon (SUNSHINE survey)
To canvas opinion concerning the role of non-invasive techniques in the assessment of patients with Raynaud's phenomenon (Rp) in clinical and research settings: four nailfold capillaroscopy methods [videocapillaroscopy (NVC), dermoscopy, stereomicroscopy, digital USB microscopy], four laser Doppler methods (laser Doppler flowmetry, imaging, anemometry/velocimetry, laser speckle contrast analysis), thermographic imaging, and upper limb arterial Doppler ultrasound. Emails with a link to the survey were sent to physicians from the European Scleroderma Trials and Research group (EUSTAR), the EULAR Study Group on Microcirculation in Rheumatic Diseases (SG_MC/RD) and members of the pediatric rheumatology Email board. The main descriptive analysis related to physicians looking after adult patients, with some analysis also of opinions from paediatric rheumatologists. 106 'adult physicians' responded (a response rate of 25.8%), of whom 68.9% were European, and 81.1% practising for more than 10 years. Nineteen paediatricians responded. The most widely available technique was NVC (72.7%). Nailfold capillaroscopy was most frequently performed by the physician him/herself, using different types of equipment relating to availability. Most rheumatologists reported high levels of appropriateness for NVC in both clinical and research settings for global assessment and differential diagnosis of Rp. Other techniques were less used. Of all the different techniques, nailfold capillaroscopy was the one most used in both clinical and research settings by adult physicians, the majority of whom use NVC in their everyday practice. The low proportion of clinicians using other techniques suggests that these are currently mainly research tools, available only in specialist centres
