A Standardized Physical Examination Method for Joints to Determine Rheumatoid Arthritis Activity Using the Modified RAND/UCLA Appropriateness Method

Q2Q1Pacientes con Artritis reumatoideIntroduction: Rheumatoid arthritis activity is evaluated based on a physical examination of each of the joints. However, the joint examination is not standardized, and the techniques are variable and difficult to reproduce due to disagreements among examiners. Objective: To recommend standardized joint examination techniques based on the modified RAND-UCLA appropriateness method. Methods: A review of the literature was conducted to determine the items to be included in the joint examination; subsequently, a consensus of rheumatologists was achieved with the modified RAND-UCLA methodology to issue the recommendations. The diagnosis of RA and differential diagnoses were excluded. Results: Two hundred fifteen rheumatologists were invited to participate. Five were included in the core group and 26 in the group of clinical experts. Clinical experience ranged between 2 and 25 years (mean 15.6 years; standard deviation 6.3 years). Most rheumatologists participated in all rounds (Round 1: 100%, Round 2: 61%, and Round 3: 61%). Of the 45 statements in the questionnaire assessing the examination techniques, 28 (62%) were retained. In addition, 6 other statements were included during the face-to-face meeting for a total of 34 final statements. Conclusion: Physical examination techniques for joints that determine RA activity are heterogeneous and differ markedly in terms of several characteristics. A list of recommendations is proposed as a guide to improve and standardize the method for the physical examination of the joints. This standardization will improve the diagnosis and results for patients with RA and help health caregivers provide better treatment.https://orcid.org/0000-0001-6528-4268https://orcid.org/0000-0002-3885-5448Revista Internacional - IndexadaA1N

Diagnostic error as a scientific and ethical challenge in establishing the activity of rheumatoid arthritis

Introducción El examen articular es una parte fundamental del examen físico del paciente con artritis reumatoide ya que permite obtener información sobre el estado de la enfermedad en un momento determinado, así como monitorizar su evolución en el tiempo. A pesar de la importancia del examen físico de las articulaciones, no existe una técnica estandarizada. Métodos Este ensayo tiene como objetivo desarrollar una discusión sobre si la estandarización del examen conjunto está justificada, para lo cual se presentan argumentos a favor y en contra. Resultados y discusión El ensayo plantea varios argumentos acerca del error diagnóstico como un desafío científico y ético cuando se trata de establecer la actividad de la artritis reumatoide. Conclusión Es el momento de adoptar una técnica de exploración física conjunta y estandarizada, que permita una mejor valoración del estado de actividad inflamatoria de la artritis reumatoide, evite los riesgos derivados de una mala clasificación del estado de la enfermedad, respete los principios éticos y no incurra en gastos innecesarios. Dejar de hacerlo tendría implicaciones científicas, económicas, éticas y de salud pública.Q4Introduction: The articular examination is an essential part of the physical examination of the patient with rheumatoid arthritis, since it gives information about the disease status at a given time and allows monitoring of its evolution over time. Despite the importance of the physical examination of the joints, it is noteworthy that there is no standardized technique. Methods: This paper aims to frame a discussion on whether standardization of the joint examination is justified, presenting arguments for and against. Results and discussion: The paper raises several arguments about diagnostic error as a scientific and ethical challenge in establishing the activity of rheumatoid arthritis. Conclusion: It is time to adopt a standardized physical joint examination technique that allows better assessment of the inflammatory activity status of the disease, avoids risks resultant from poor disease status classification, adheres to ethical principles and does not incur unnecessary expenses. Failure to do so would have scientific, economic, ethical, and public health implicationsRevista Nacional - IndexadaS

Síndromes paraneoplásicos neurológicos: para entender la respuesta inmune y los anticuerpos paraneoplásicos

Los síndromes paraneoplásicos neurológicos (SPN) comprometen el sistema nervioso (central periférico o neu-romuscular) de forma focal o difusa y se deben a una respuesta inmune de tipo humoral o celular sin que haya metástasis o extensión directa del tumor, su incidencia es baja. El SPN hace que el sistema inmune medie su respuesta a través de las células T principalmente cuando los antígenos son de localización intracelular, pero cuando los antígenos se localizan en la membrana celular se ha observado una mediación por anticuerpos. Los SPN pueden preceder la aparición de un tumor. Los anticuerpos onconeuronales permiten limitar su espectro diferencial y facilitan el diagnóstico y tratamiento tempranos. Los síndromes neurológicos no paraneoplásicos y sin un tumor subyacente son entidades importantes para el diagnóstico diferencial, en ellos hay una mediación por anticuerpos contra las proteínas sinápticas y de la superficie celular y comparten características clínicas con los SPN; afectan niños y adultos jóvenes y pueden responder a inmunoterapia. El objetivo de este artículo es explorar las características de los SPN y los mecanismos inmunológicos que los identifican, definir los anticuerpos mejor estudiados y presentar un plan de diagnóstico y tratamiento

Association between Postural Orthostatic Tachycardia Syndrome and Joint Hypermobility

Joint hypermobility syndrome refers to increased joint flexibility beyond the normal range of motion. This syndrome has a benign form known as Ehlers-Danlos syndrome type 3. This is a disorder in which hypermobility is accompanied by clinical manifestations in the absence of any systemic disease. A clinical finding associated with this condition is postural orthostatic tachycardia syndrome. The following is a rare case of joint hypermobility syndrome and postural orthostatic tachycardia syndrome. The relevance of this case report lies in the impact that this disease had on the patient’s quality of life and the limitation in the performance of activities of daily living

Reporting items for capillaroscopy in clinical research on musculoskeletal diseases: A systematic review and international Delphi consensus

Objectives: The level of detail included when describing nailfold videocapillaroscopy (NVC) methods varies among research studies, making interpretation and comparison of results challenging. The overarching objective of the present study was to seek consensus on the reporting standards in NVC methodology for clinical research in rheumatic diseases and to propose a pragmatic reporting checklist. Methods: Based on the items derived from a systematic review focused on this topic, a three-step web-based Delphi consensus on minimum reporting standards in NVC was performed among members of the European League against Rheumatism (EULAR) Study Group on Microcirculation in Rheumatic Diseases and the Scleroderma Clinical Trials Consortium. Results: A total of 319 articles were selected by the systematic review, and 46 items were proposed in the Delphi process. This Delphi exercise was completed by 80 participants from 31 countries, including Australia and countries within Asia, Europe, North America and South America. Agreement was reached on items covering three main areas: Patient preparation before NVC (15 items), device description (5 items) and examination details (13 items). Conclusion: Based on the available evidence, the description of NVC methods was highly heterogeneous in the identified studies and differed markedly on several items. A reporting checklist of 33 items, based on practical suggestions made (using a Delphi process) by international participants, has been developed to provide guidance to improve and standardize the NVC methodology to be applied in future clinical research studies
