ABSTRACT

Abstract Objectives: Describe Brazilian rheumatologists's competence in interventional rheumatology; assess the association between this ability and demographic and training variables. Methods: A cross-sectional study with 500 Brazilian rheumatologists. Participants were assessed by self-administered questionnaire consisting of demographics, training, practice in office and knowledge in interventional rheumatology data. Results: 463 participants had their data analyzed. The mean age was 40.2 years (±11.2). 70% had performed periarticular injections and 78% had performed intra-articular injections. The sample was divided into three groups: non-interventionist, little interventionist and very interventionist. The non-interventionist group showed (p < 0.001-0.04) higher mean age, lower proportion of university bond, lower training history, higher proportion of graduates in the Southeast country, and higher proportion of graduates in the 1980s to 1989. The very interventionist group showed higher (p < 0.001-0.018) proportion of adult rheumatologists, higher proportion of university bond, longer training time with greater practice of complex procedures, and higher proportion of graduates, trained and with private practice in the South country. Variables most associated with the very interventionist subgroup are performing axial intra-articular injections (OR: 7.4, p < 0.001), synovial biopsy (OR: 5.75, p = 0.043), image-guided IAI (OR: 4.16, p < 0.001), viscosupplementation (OR = 3.41, p < 0.001), joint lavage (OR = 3.22, p = 0.019), salivary gland biopsy (OR = 2.16, p = 0.034) and over 6-month training (OR: 2.16, p = 0.008). Conclusions: Performing more complex invasive procedures and over 6-month training in interventional rheumatology were variables associated with enhanced interventional profile.


Resumo Objetivos: Descrever a competência dos reumatologistas brasileiros na reumatologia intervencionista (RI); avaliar a associação entre essa capacidade e variáveis demográficas e de treinamento. Métodos: Fez-se um estudo transversal com 500 reumatologistas brasileiros. Os participantes foram avaliados por questionário autoadministrado, constituído por dados demográficos, treinamento, prática em consultório e conhecimento em dados de RI. Resultados: Analisaram-se os dados de 463 participantes. A média foi de 40,2 anos (± 11,2). Desses, 70% fizeram injeções periarticulares (IPA) e 78% intra-articulares (IIA). A amostra foi dividida em três grupos: não intervencionista, pouco intervencionista e muito intervencionista. O grupo não intervencionista apresentou (p < 0,001 - 0,04) maior média de idade, menor proporção de vínculo universitário, menor história de treinamento, maior proporção de graduados na Região Sudeste do país e maior proporção de graduados nas décadas de 1980 a 1989. O grupo muito intervencionista apresentou (p < 0,001 - 0,018) maior proporção de reumatologias que atendem pacientes adultos, maior proporção de vínculo universitário, maior tempo de treinamento de prática de procedimentos complexos, maior proporção de graduados no sul do país, treinados e com consultório particular nessa região. As variáveis mais frequentemente associadas ao subgrupo muito intervencionista foram realização de IIA axial (OR: 7,4, p < 0,001), biópsia sinovial (OR: 5,75, p = 0,043), IIA guiada por imagem (OR: 4,16, p < 0,001), viscossuplementação (OR = 3,41, p < 0,001), lavagem articular (OR = 3,22, p = 0,019), biópsia da glândula salivar (OR = 2,16, p = 0,034) e mais de seis meses de treinamento (OR: 2,16; p = 0,008). Conclusões: Fazer procedimentos invasivos mais complexos e ter mais de seis meses de treinamento em RI foram as variáveis associadas a um maior perfil intervencionista.

ABSTRACT

OBJETIVO: Analisar os efeitos da injeção repetida de betametasona na concentração de proteoglicanos da cartilagem articular do joelhos normais de coelhos californianos de ambos os sexos. MÉTODOS: Os animais foram randomizados em oito grupos de dez animais cada. Três grupos controle (injeção ou não de solução salina isotônica) e cinco grupos de estudo - doses terapêuticas, repetidas ou não, de betametasona injetadas no joelho direito de cada coelho, com intervalos semanais. Após oito dias da última injeção prevista, cortes histológicos da cartilagem das áreas de apoio dos platôs tibiais foram corados com hematoxilina e eosina para análise por microscopia óptica, e com safranina O para a pesquisa da quantidade de proteoglicanos. A intensidade da coloração da safranina O foi quantificada em aparelho de histomorfometria, composto por microscópio Olympus BX 50 e microcomputador com software Image Pro-plus 4.5Ò. RESULTADOS: Não houve diferenças nos animais que tiveram seus joelhos injetados com betametasona uma, duas e quatro vezes quando comparados com os grupos controle. Nos animais que receberam seis e oito aplicações a intensidade da coloração com safranina O reduziu-se significativamente (p < 0,05) quando comparada tanto com grupos controle quanto com os outros de estudo. CONCLUSÃO: Foi possível demonstrar redução da concentração de proteoglicanos na matriz cartilaginosa articular dependente do efeito deletério cumulativo das repetidas injeções intra-articulares de betametasona.


OBJECTIVE: To study the effects of repeated injections of betamethasone on proteoglycan concentration in the articular cartilage of normal knees of Californian rabbits of both sexes. METHODS: Eighty animals were randomly divided into eight groups of ten animals each. Three control groups (saline solution injected or not) and five study groups - therapeutical doses, repeated or not, of betamethasone injected into the right knee of each animal at weekly intervals. After eight days from the last injection, sections of articular cartilage from tibial plateaus collected from weight-bearing surfaces were stained with hematoxylin and eosin for light microscopy analysis and with safranin O for the proteoglycan content assay. The staining intensity of safranin O was quantified by histomorphometry using an Olympus BX 50 microscope and a microcomputer with the Image Pro-plus 4.5Ò software. RESULTS: Animals receiving one, two and four betamethasone injections showed no differences when compared to normal controls. Animals receiving six and eight injections had a significant decrease in safranin O staining intensity (p < 0.05) as compared to the control groups and the other study groups. CONCLUSION: A decrease in the concentration of articular cartilage proteoglycans dependent on repeated betamethasone injection was effectively demonstrated.

ABSTRACT

Several medications are commonly injected intra-articularly for postoperative analgesia after arthroscopic knee surgery. Among the potentially efficient substances, magnesium could be of particular interest through its NMDA-receptor blocking properties. We designed this study to determine whether intra-articular [IA] magnesium sulphate [MgSO4] results in better analgesia and whether its combination with bupivacaine would provide superior analgesia to either drug alone. We evaluated 60 outpatients undergoing arthroscopic menisectomy under general anesthesia. After conclusion of surgery, patients were randomized into three groups: Group I received IA 20 mL 0.5% bupivacaine added to 10 mL 0.9% normal saline; Group II received IA 10 mL 10% magnesium sulphate [MgSO4] added to 20 mL 0.9% normal saline; Group III received IA 20 mL 0.5% bupivacaine added to 10 mL 10% magnesium sulphate [MgSO4]. This study revealed a significant benefit from the individual IA administration of both bupivacaine and magnesium sulphate. The combination of these drugs resulted in better postoperative analgesia as well as an increased analgesic duration compared with either drug alone. We conclude that IA magnesium sulphate and bupivacaine improved comfort compared with either drug alone in outpatients undergoing arthroscopic knee surgery. They increased time to first analgesic request, decreased need for postoperative analgesics, and lowered pain scores after arthroscopic knee surgery
