Abstract Serrated polyposis syndrome is considered the most prevalent colonic polyposis syndrome in the world. Its importance has been increasingly discussed due to the significant increase in the risk of developing colorectal cancer in its affected individuals, similarly to other well-known polyposis syndromes, such as familial adenomatous polyposis. Serrated lesions of the colon play a major role in this syndrome represented by hyperplastic polyps, serrated sessile lesions and traditional serrated adenomas. Among these lesions, the sessile serrated lesion stands out, considered the main precursor lesion of the serrated pathway of colon carcinogenesis. Diagnosis of serrated polyposis syndrome is given through colonoscopy examination. Diagnostic criteria are: 1) 5 or more serrated lesions proximal to the rectum, all >4mm in size, with at least two >9mm in size; or 2) 20 serrated lesions of any size located anywhere in the large intestine, with >4 lesions proximal to the rectum. The ideal treatment is removal of all relevant serrated lesions by colonoscopy. In case of failure of endoscopic therapy, surgery is indicated. This manuscript is based on two case reports and a literature review and aims to broaden the discussion about the subject.

ABSTRACT The oral involvement in the Hematopoietic Stem Cell Transplantation is well described in the literature. The goal of the dental treatment and management of the oral lesions related to the HSCT is to reduce the harm caused by preexisting oral infection or even the worsening of oral acute/chronic GVHD and late effects. The aim of this guideline was to discuss the dental management of patients subjected to HSCT, considering three phases of the HSCT: pre-HSCT, acute phase, and late phase. The literature published from 2010 to 2020 was reviewed in order to identify dental interventions in this patient population. The selected papers were divided into three groups: pre-HSCT, acute and late, and were reviewed by the SBTMO Dental Committee's members. When necessary, an expertise opinion was considered for better translating the guideline recommendations to our population dental characteristics. This manuscript focused on the pre-HSCT dental management. The objective of the pre-HSCT dental management is to identify possible dental situations that On behalf of the Dental Committee of the Brazilian Society of Gene Therapy and Bone Marrow Transplantation (SBTMO) can worsening during the acute phase after the HSCT. Each guideline recommendations were made considering the Dentistry Specialties. The clinical consensus on dental management prior to HSCT provides professional health caregivers with clinical setting-specific information to help with the management of dental problems in patients to be subjected to HSCT.

Abstract This study evaluated color stability (CS), anti-adherence effect (AAE), and cell viability of microorganisms on acrylic resin (AR) surface, treated associated or not with sodium percarbonate (SP). AR specimens were prepared, and color analysis was performed before and after the treatments and the CS was calculated. For analysis of AAE, the samples were sterilized by radiation in a microwave oven. Then samples were randomly distributed: phosphate-buffered saline (PBS - control), 0.5% sodium hypochlorite (SH), phytosphingosine (PHS), and phytosphingosine + SP (PHS+Na2CO3). The specimens remained in contact with solutions for 30 minutes and were later contaminated by Candida albicans. Aliquots were seeded in Petri dishes with Sabouraud Dextrose agar and incubated at 37°C for 24 hours. After the incubation, the number of colonies was counted. The cell viability of adhered microorganisms on the AR was evaluated and 20 fields were observed under an epifluorescence microscope, and the percentage of adhered viable cells was calculated. Data were compared (One-way ANOVA, Tukey, p<.05). As for CS, PHS+ Na2CO3 (0.4±0.1) resulted in less change than PBS (0.9±0.2), similar to the other groups (SH [1.0±0.3)]; PHS [0.9±0.2)]). There was no difference for all tested solutions regarding the ability to avoid microorganism adherence (p>0.05), but PHS (11.2±4.1) resulted in a smaller area of adhered viable cells, statistically different from SH (18.2±7.6) and PBS (26.4±10.8). It was concluded that PHS resulted in lower adhered viable cells and when associated with Na2CO3, also shows a lower effect on the CS of AR.

Resumo Este estudo avaliou estabilidade de cor (EC), efeito antiaderente (EAA) e viabilidade celular de microrganismos em superfície de resina acrílica (RA), tratada com solução de fitoesfingosina, associada ou não ao percarbonato de sódio (PS). Espécimes RA foram preparados e análise de cor foi realizada antes e após os tratamentos e EC foi calculada. Para análise de EAA, as amostras foram esterilizadas por radiação em forno de micro-ondas. Então foram distribuídas aleatoriamente: solução salina tamponada com fosfato (PBS - controle), hipoclorito de sódio 0,5% (SH), fitoesfingosina (PHS) e fitoesfingosina + SP (PHS+Na2CO3). Os espécimes permaneceram em contato com as soluções por 30 minutos e posteriormente foram contaminados por Candida albicans. Alíquotas foram semeadas em placas de Petri com ágar Sabouraud Dextrose e incubadas a 37°C por 24 horas. Após a incubação, o número de colônias foi contado. A viabilidade celular dos microorganismos aderidos na RA foi avaliada e 20 campos foram observados em microscópio de epifluorescência, e a porcentagem de células viáveis aderidas foi calculada. Os dados foram comparados (One-way ANOVA, Tukey, p<0,05). Quanto a EC, o PHS+ Na2CO3 [0,4 (0,1)] resultou em menor alteração que o PBS [0,9 (0,2)], semelhante aos demais grupos (SH [1,0 (0,3)]; PHS [0,9 (0,2)]). Não houve diferença para todas as soluções testadas quanto à capacidade de evitar a aderência de microorganismos (p>0,05), mas o PHS [11,2 (4,1)] resultou em uma área menor de células viáveis aderidas, estatisticamente diferente do SH [18,2 (7,6)] e PBS [26,4 (10,8)]. Concluiu-se que o PHS resultou em menor número de células viáveis aderidas e, quando associado ao Na2CO3, também apresenta menor efeito sobre o EC da RA.

ABSTRACT Species of the Amaranthus genus are very versatile and have potential for the application in the development of commercial products. The near infrared spectroscopy (NIR) is an efficient tool that can help in the quality control of products, quickly and non-destructive to the sample. The goal of this study was to carry out the distinction of seed and oils of different Amaranthus species using the near infrared spectroscopy. Three species were used: A. viridis L., A. hybridus L. e Amaranthus sp. (commercial). The spectra acquired from the sample using the near infrared spectroscopy were submitted to the partial least squares discriminant analysis (PLS-DA) and to the principal component analysis (PCA). Through PCA, it was possible to differentiate the Amaranthus species both for seeds and oils. Through PLS-DA, it was possible to predict the classes of the species with high degree of correct classification, with 96.67% of correct classifications for seeds and 98.89% for oil. Thus, with the use of the near infrared spectroscopy associated with the multivariate statistical analysis, it is possible to classify the different Amaranthus species, especially when using the oil.

Abstract Objective To evaluate the impact of the race (Black versus non-Black) on maternal and perinatal outcomes of pregnant women with COVID-19 in Brazil. Methods This is a subanalysis of REBRACO, a Brazilian multicenter cohort study designed to evaluate the impact of COVID-19 on pregnant women. From February2020 until February 2021, 15 maternity hospitals in Brazil collected data on women with respiratory symptoms. We selected all women with a positive test for COVID-19; then, we divided them into two groups: Black and non-Black women. Finally, we compared, between groups, sociodemographic, maternal, and perinatal outcomes. We obtained the frequency of events in each group and compared them using X2 test; p-values < 0.05 were considered significant. We also estimated the odds ratio (OR) and confidence intervals (CI). Results 729 symptomatic women were included in the study; of those, 285 were positive for COVID-19, 120 (42.1%) were Black, and 165 (57.9%) were non-Black. Black women had worse education (p = 0.037). The timing of access to the health system was similar between both groups, with 26.3% being included with seven or more days of symptoms. Severe acute respiratory syndrome (OR 2.22 CI 1.17–4.21), intensive care unit admission (OR 2.00 CI 1.07–3.74), and desaturation at admission (OR 3.72 CI 1.41–9.84) were more likely to occur among Black women. Maternal death was higher among Black women (7.8% vs. 2.6%, p = 0.048). Perinatal outcomes were similar between both groups. Conclusion Brazilian Black women were more likely to die due to the consequences of COVID-19.

Resumo Objetivo Avaliar o impacto da raça (negra versus não negra) nos desfechos maternos e perinatais de gestantes com COVID-19 no Brasil. Métodos Esta é uma subanálise da REBRACO, um estudo de coorte multicêntrico brasileiro desenhado para avaliar o impacto da COVID-19 em mulheres grávidas. De fevereiro de 2020 a fevereiro de 2021, 15 maternidades do Brasil coletaram dados de mulheres com sintomas respiratórios. Selecionamos todas as mulheres com teste positivo para COVID-19; em seguida, as dividimos em dois grupos: mulheres negras e não negras. Finalmente, comparamos, entre os grupos, os resultados sociodemográficos, maternos e perinatais. Obtivemos a frequência dos eventos em cada grupo e comparamos usando o teste X2; Valores de p <0,05 foram considerados significativos. Também estimamos o odds ratio (OR) e os intervalos de confiança (IC). Resultados 729 mulheres sintomáticas foram incluídas no estudo; desses, 285 foram positivos para COVID-19, 120 (42,1%) eram negros e 165 (57,9%) não eram negros. As mulheres negras apresentaram pior escolaridade (p = 0,037). O tempo de acesso ao sistema de saúde foi semelhante entre os dois grupos, com 26,3% incluídos com sete ou mais dias de sintomas. Síndrome respiratória aguda grave (OR 2,22 CI 1,17–4,21), admissão em unidade de terapia intensiva (OR 2,00 CI 1,07–3,74) e dessaturação na admissão (OR 3,72 CI 1,41–9,84) foram mais prováveis de ocorrer entre mulheres negras. A mortalidade materna foi maior entre as negras (7,8% vs. 2,6%, p = 0,048). Os resultados perinatais foram semelhantes entre os dois grupos. Conclusão Mulheres negras brasileiras tiveram maior probabilidade de morrer devido às consequências da COVID-19.

ABSTRACT Purpose: To evaluate the impact of social isolation due to the COVID-19 pandemic on the number of new cases and therapeutic approaches at the Ocular Oncology division from the Universidade Federal de São Paulo (UNIFESP). Methods: A retrospective study was conducted by medical records review of new patients treated before the pandemic from March 2019 to September 2019 (pre-pandemic group) and during the pandemic from March 2020 to September 2020 (pandemic group). Data regarding age, sex, ethnicity, place of origin, clinical diagnosis, time since referral, and proposed therapy were analyzed. Results: We analyzed 186 new cases, 122 from the pre-pandemic group and 64 from the pandemic group, representing a decrease of 47.54% in new cases. There was no statistically significant change in sex, race, state of origin, history of cancer, age, or time with suspected cancer (p>0.05). A higher frequency of malignancies was observed in the pandemic group (68%) when compared to the pre-pandemic group (48.48%). Benign tumors were the most common diagnosis in the pre-pandemic group (41.80%), while conjunctival squamous cell carcinoma was the modal diagnosis in the pandemic group (31.25%). There was a decreasing trend (p=0.097) in the number of surgeries (-7.63%) and an increase in topical treatment (+10.68%). There was also a tendency to perform fewer surgeries in benign tumors and decreased follow-up visits. Conclusion: Our findings showed a significant decrease in the number of new cases referred to the Ocular Oncology service. Moreover, the pandemic led to a switch in the therapeutic approach with preference to non-invasive treatments that would demand operating rooms. A drastic increase of cases perhaps in advanced stages might be expected because of the decrease observed in the first six months of quarantine.

RESUMO Objetivo: Avaliar o impacto do isolamento social devido à pandemia COVID-19 sobre o número de casos novos e abordagens terapêuticas. Métodos: Estudo retrospectivo por revisões de prontuários de novos pacientes tratados antes da pandemia, de março de 2019 a setembro de 2019 (grupo pré-pandemia), e durante a pandemia, de março de 2020 a setembro de 2020 (grupo pandemia). Dados analisados incluíram idade, sexo, etnia, local de origem, diagnóstico clínico, tempo desde o encaminhamento e terapia proposta. Resultados: Um total de 186 novos casos foram analisados, sendo 122 do grupo pré-Pandemia e 64 do grupo Pandemia, representando uma redução de 47,54%. Não houve alteração estatisticamente signi ficativa quanto a sexo, raça, estado de origem, história do câncer, idade ou tempo de encaminhamento (p>0,05). Observou-se maior frequência de malignidades no grupo pandemia (68%) quando comparado com o grupo pré-pandemia (48,48%). Os tumores benignos foram os casos mais diagnosticados no grupo pré-pandemia (41,80%), enquanto no grupo pandemia o diagnóstico mais frequente foi o carcinoma de células escamosas de conjuntiva (31,25%). Houve tendência (p=0,097) de diminuição no número de cirurgias (-7,63%) e de aumento no tratamento tópico (+10,68%). Houve também uma tendência a diminuição de indicação cirúrgica em tumores benignos e diminuição dos retornos imediatos. Conclusão: Nossos achados mostram uma diminuição significativa no número de novos casos encaminhados ao setor de Oncologia Ocular. Além disso, a pandemia levou a uma mudança na abordagem terapêutica com preferência a tratamentos não invasivos, a fim de evitar o uso de salas de cirurgia. Um aumento drástico de casos, talvez em estágios avançados, pode ser esperado como resultado da diminuição observada nos primeiros 6 meses de quarentena.

ABSTRACT Serodiagnosis of strongyloidiasis is usually performed by ELISA for the detection of IgG antibodies due to its high sensitivity and practicality, but its main limitation is a constant source of S. stercoralis antigens. The use of S. venezuelensis as a heterologous source of antigens has facilitated several published studies on the serodiagnosis and epidemiology of human strongyloidiasis. The main objective of this study was to evaluate the diagnostic accuracy of surface cuticle antigens of infective larvae of S. venezuelensis extracted with CTAB detergent (L3-CTAB) in comparison with soluble somatic extracts (L3-SSE) using a panel of sera from immunocompetent and immunocompromised individuals, at three different cut-offs. ROC curve analysis showed that L3-CTAB had an AUC of 0.9926. At the first cut-off value (OD 450 nm = 0.214), sensitivity and specificity were 100% and 90.11%, respectively, with a diagnostic accuracy of 0.93. At a second cut-off value (OD 450 nm = 0.286), sensitivity and specificity were 70% and 100%, respectively, with a diagnostic accuracy of 0.91. However, at an alternative third cut-off value (OD 450 nm = 0.589), sensitivity and specificity were 95% and 97.8%, respectively, with a diagnostic accuracy of 0.97. Using L3-CTAB as an antigenic source, the seropositivity rate in immunocompromised patients was 28.13% (9/32) whereas a seropositivity rate of 34.38% (11/32) was found when L3-SSE was used in ELISA. Therefore, the L3-CTAB is simple and practical to obtain and was found to be highly sensitive and specific.

ABSTRACT BACKGROUND: Occult hepatitis B virus infection (OBI) is defined as the presence of hepatitis B virus (HBV) deoxyribonucleic acid (DNA) in the liver of individuals with undetectable hepatitis B virus surface antigen (HBsAg) in the serum. The actual prevalence of OBI and its clinical relevance are not yet fully understood. OBJECTIVE: To evaluate the prevalence of HBV DNA in liver biopsies of HBsAg-negative patients with chronic liver disease of different etiologies in a referral center in Brazil and compare two different HBV DNA amplification protocols to detect HBV. DESIGN AND SETTING: This cross-sectional observational study was conducted at the Liver Outpatient Clinic, Hospital das Clínicas, Universidade Federal de Minas Gerais, Belo Horizonte, MG, Brazil, between January 2016 and December 2019. METHODS: HBV DNA was investigated in 104 liver biopsy samples from individuals with chronic liver disease of different etiologies, in whom HBsAg was undetectable in serum by nested-polymerase chain reaction (nested-PCR), using two different protocols. RESULTS: OBI, diagnosed by detecting HBV DNA using both protocols, was detected in 6.7% of the 104 individuals investigated. Both protocols showed a good reliability. CONCLUSION: In addition to the differences in the prevalence of HBV infection in different regions, variations in the polymerase chain reaction technique used for HBV DNA amplification may be responsible for the large variations in the prevalence of OBI identified in different studies. There is a need for better standardization of the diagnostic methods used to diagnose this entity.

Abstract This study evaluated the bioactive potential of a macro-porous chitosan scaffold incorporated with calcium hydroxide (CH-Ca) and functionalized with bioactive doses of simvastatin (SV) for bone tissue regeneration. Initially, the bioactive dose of SV in osteoblastic cells (SAOS-2) was determined. For the direct contact experiment, SAOS-2 cells were plated on scaffolds to assess cell viability and osteogenic differentiation. The second assay was performed at a distance using extracts from scaffolds incubated in culture medium to assess the effect of conditioned medium on viability and osteogenic differentiation. The initial screening showed that 1 μM SV presented the best biostimulating effects, and this dose was selected for incorporation into the CH-Ca and pure chitosan (CH) scaffolds. The cells remained viable throughout the direct contact experiment, with the greatest cell density in the CH-Ca and CH-Ca-SV scaffolds because of their higher porosity. The CH-Ca-SV scaffold showed the most intense bio-stimulating effect in assays in the presence and absence of osteogenic medium, leading to an increased deposition of mineralized matrix. There was an increase in the viability of cells exposed to the extracts for CH-Ca, CH-SV, and CH-Ca-SV during the one-day period. There was an increase in ALP activity in the CH-Ca and CH-Ca-SV; however, the CH-Ca-SV scaffold resulted in an intense increase in the deposition of mineralized nodules, approximately 56.4% at 7 days and 117% at 14 days, compared with CH (control). In conclusion, functionalization of the CH-Ca scaffold with SV promoted an increase in bioactivity, presenting a promising option for bone tissue regeneration.

ABSTRACT This study evaluated the behavior of broiler chickens subjected to thermal stress during different periods of the day and age of birds. A total of 180 one-day-old male broiler chicks were allocated to three chambers. Each chamber contained five boxes, with 12 chicks/box. Birds were assigned to a completely randomized design. The birds were filmed, and the images recorded every minute during the two periods: morning (from 08:00 to 09:00 h) and afternoon (from 17:00 to 18:00 h), at 7, 14, and 35 d of age. The frequency of the behavioral category (water intake, feed intake, resting, exploration, and comfort) was determined. Data were subjected to variance analysis for mixed models with rearing temperatures (cold, usual, and hot) and age of birds (7, 14, and 35 d) as subdivided plot, and periods of the day (morning and afternoon) as sub-subdivided plot. Birds at cold and usual temperatures showed higher feed intake than those at hot temperature in the morning. Birds exposed to cold and usual temperatures explored the environment less frequently at 35 d when compared with 14 d. However, chickens at hot temperature showed decreased exploration according to the increase of age. Birds spent more time feeding during the morning, regardless of age and rearing temperature. Also, during this period of the day, chickens spent most of the time exploring the environment. The frequency of feed intake and exploration decreases with the increase of age. The similarity of behavior between chickens reared at cold and usual temperatures may be due to a change in the thermal comfort zone of the birds. It suggests that the real thermal comfort temperature is between the two temperature ranges studied (cold and usual).

ABSTRACT Little is known about how Brazilian dentists’ treatment decisions for proximal carious lesions are compared to current evidence-based recommendations, so better understanding is needed to close any potential evidence-practice gap. Objectives: This cross-sectional study aimed to quantify the evidence-practice gap about proximal carious lesions treatment and identify dentist factors associated with this evidence-practice gap. Methods: Brazilian dentists (n=214) from Araraquara, São Paulo State, “completed a questionnaire about their dentist and practice characteristics and a translated version of the “Assessment of Caries Diagnosis and Caries Treatment” from the U.S. National Dental Practice-Based Research Network. Five radiographic images of proximal carious lesions in low-risk and high-risk patient scenarios were used. Associations between treatment recommendations and lesion, dentist, and practice characteristics were tested for statistical significance (p<0.05). Results: Lesions confined to the enamel would be restored by 35% and 71% of dentists in the low-risk and high-risk patient scenarios, respectively, suggesting a substantial evidence-practice gap given that surgical intervention of enamel lesions is not consistent with current evidence. The lesion depth threshold to recommend a permanent restoration differed between the low-risk and high-risk patient scenarios (p<0.001). Specific dentist/practice characteristics (dentist gender, graduate of a public dental school, postgraduate training, use of caries risk assessment) were significantly associated with the evidence-practice gap, but the magnitude of these differences was not major Conclusion: A substantial evidence-practice gap in treatment of proximal carious lesions was found for the sample overall, even when clinical scenarios presented low-risk patients. Global strategies are needed to close this substantial evidence-practice gap.

RESUMO Pouco se sabe se as decisões de tratamento dos dentistas brasileiros para lesões cariosas proximais são comparadas às recomendações atuais baseadas em evidências, portanto, é necessário um melhor entendimento para fechar qualquer potencial lacuna entre a evidência e a prática. Purpose: Este estudo transversal teve como objetivo quantificar a lacuna entre a evidência e a prática na decisão de tratamento das lesões cariosas proximais e identificar os fatores associados a essa lacuna entre a evidência e a prática. Methods: Cirurgiões-dentistas brasileiros (n=214) de Araraquara, Estado de São Paulo, preencheram um questionário sobre suas características odontológicas e clínicas e uma versão traduzida do “Assessment of Caries Diagnosis and Caries Treatment” da U.S. National Dental Practice-Based Research Network. Cinco imagens radiográficas de lesões cariosas proximais em cenários de pacientes de baixo risco e alto risco foram usadas. Associações entre recomendações de tratamento e lesão, dentista e características da prática foram testadas (p<0,05). Results: As lesões confinadas ao esmalte seriam restauradas por 35% e 71% dos dentistas nos cenários de pacientes de baixo risco e alto risco, respectivamente, sugerindo uma lacuna entre a evidência e a prática substancial, dado que a intervenção cirúrgica das lesões do esmalte não é consistente com as evidências atuais. O limiar de profundidade da lesão para recomendar uma restauração permanente diferiu entre os cenários de pacientes de baixo risco e alto risco (p<0,001). Características específicas do dentista/prática (sexo do dentista, graduado em uma faculdade pública, pós-graduação, uso da avaliação de risco de cárie) foram significativamente associadas à lacuna entre a evidência e a prática, mas a magnitude dessas diferenças não foi importante. Conclusions: uma lacuna entre a evidência e a prática substancial na decisão de tratamento de lesões cariosas proximais foi encontrada para a amostra como um todo, mesmo quando os cenários clínicos apresentavam pacientes de baixo risco. Estratégias globais são necessárias para fechar essa lacuna entre a evidência e a prática.

Abstract: En | Text: En | PDF: En

ABSTRACT The SISBIOTA-BRASIL was a three-year multimillion-dollar research program of the Brazilian government to document plants and animals in endangered/understudied areas and biomes in Brazil. Distributional patterns and the historical events that generated them are extensively unknown regarding Brazilian fauna and flora. This deficiency hinders the development of conservation policies and the understanding of evolutionary processes. Conservation decisions depend on precise knowledge of the taxonomy and geographic distribution of species. Given such a premise, we proposed to research the diversity of Diptera of the Brazilian western arc of Amazon, Cerrado, and Pantanal in the states of Mato Grosso, Mato Grosso do Sul, and Rondônia. Three important biomes of the South American continent characterize these Brazilian states: Amazon forest, Cerrado (Brazilian Savannah), and Pantanal. Besides their ecological relevance, these biomes historically lack intensive entomological surveys. Therefore, they are much underrepresented in the Brazilian natural history collections and in the scientific literature, which is further aggravated by the fact that these areas are being exponentially and rapidly converted to commercial lands. Our project involved over 90 collaborators from 24 different Brazilian institutions and one from Colombia among researchers, postdocs, graduate and undergraduate students, and technicians. We processed and analyzed nearly 300,000 specimens from ~60 families of Diptera collected with a large variety of methods in the sampled areas. Here, we provide a detailed overview of the genera and species diversity of 41 families treated. Our results point to a total of 2,130 species and 514 genera compiled and identified for the three states altogether, with an increase of 41% and 29% in the numbers of species and genera known for the three states combined, respectively. Overall, the 10 most species-rich families were Tachinidae, Cecidomyiidae, Tabanidae, Psychodidae, Sarcophagidae, Stratiomyidae, Bombyliidae, Syrphidae, Tephritidae, and Asilidae. The 10 most diverse in the number of genera were Tachinidae, Stratiomyidae, Asilidae, Mycetophilidae, Syrphidae, Tabanidae, Muscidae, Dolichopodidae, Sarcophagidae, and Chloropidae. So far, 111 scientific papers were published regarding taxonomic, phylogenetic, and biogeographical aspects of the studied families, with the description of 101 new species and three new genera. We expect that additional publications will result from this investigation because several specimens are now curated and being researched by specialists.

Resumo Objetivo: Descrever os achados de ressonância magnética (RM) mais prevalentes em pacientes com diagnóstico clínico de polimialgia reumática (PMR). Materiais e Métodos: Dezesseis pacientes com PMR não tratada, classificados pelos critérios do American College of Rheumatology, foram submetidos a RM do ombro e/ou quadril, segundo suas queixas clínicas. Seis pacientes também foram submetidos a RM da coluna. Resultados: Foram avaliados 24 ombros, identificando-se bursite subacromial-subdeltoide em 21 (87,5%), sinovite glenoumeral em 17 (70,8%) e distensão líquida da bainha do tendão da cabeça longa do bíceps em 15 (62,5%). Peritendinite e edema capsular foram observados em 21 (87,5%) e 17 (70,8%) ombros, respectivamente. Dezessete quadris foram analisados, identificando-se sinovite em 12 (70,6%), bursite trocantérica em 11 (64,7%), peritendinite em 17 (100%) e edema capsular em 14 (82,4%). Os seis pacientes que realizaram RM da coluna apresentavam bursite interespinhosa. Conclusão: Bursite subacromial-subdeltoide, sinovite glenoumeral e do quadril são achados de imagem prevalentes em pacientes com PMR. Além disso, achados como peritendinite e edema capsular tiveram alta prevalência nesses pacientes. Estudos de caso- controle devem ser realizados para validar esses dados e estabelecer o real impacto desses achados no diagnóstico de PMR.

Abstract Objective: To describe the prevalence of magnetic resonance imaging (MRI) findings in patients with the clinical diagnosis of polymyalgia rheumatica (PMR). Materials and Methods: Sixteen consecutive patients with untreated PMR, meeting the American College of Rheumatology criteria, underwent MRI examinations of the shoulder(s), hip(s), or both, depending on clinical complaints. Six patients also underwent MRI of the spine. Results: We evaluated 24 shoulders, among which we identified subacromial-subdeltoid bursitis in 21 (87.5%), glenohumeral joint effusion in 17 (70.8%), and fluid distention of the long head of the biceps tendon sheath in 15 (62.5%). Peritendinitis and capsular edema were observed in 21 (87.5%) and 17 (70.8%) shoulders, respectively. We also evaluated 17 hips, identifying hip joint effusion in 12 (70.6%), trochanteric bursitis in 11 (64.7%), peritendinitis in 17 (100%), and capsular edema in 14 (82.4%). All six of the patients who underwent MRI of the spine were found to have interspinous bursitis. Conclusion: Subacromial-subdeltoid bursitis, glenohumeral joint effusion, and hip joint effusion are common findings in patients with PMR. In addition, such patients appear to be highly susceptible to peritendinitis and capsular edema. There is a need for case-control studies to validate our data and to determine the real impact that these findings have on the diagnosis of PMR by MRI.
