RESUMO

BACKGROUND: Pain is not a trivial issue for hidradenitis suppurativa (HS) patients and has been considered a domain in the Core Outcome Set. To date, there is no evidence about pain caused by the ultrasound examinations. OBJECTIVE: The aim of the study was to assess the presence of pain generated by the ultrasound examinations of HS patients. METHODS: A multicentric cross-sectional study for detecting pain during the ultrasound examinations of HS patients using a validated verbal questionnaire immediately after the imaging studies. Statistical analysis included demographic data and possible associations with sex, age, location, clinical (Hurley), and ultrasonographic scoring (SOS-HS). The statistical tests were two proportions Z test, χ2 test, Student's t test, and ANOVA. A p < 0.05 was considered significant. RESULTS: 317 patients met the criteria. 77.3% of them did not present pain. Of cases with pain, 59.8% were mild, 16.7% moderate, and 23.6% severe. No significant association was found with sex, age, staging, location, or the number of affected regions. Although nonsignificant, severe pain cases were more frequent in the clinical Hurley III and ultrasonographic SOS-HS III stages. CONCLUSION: Pain generated by the ultrasound examination of HS patients is infrequent.

RESUMO

A patela é o maior osso sesamoide do corpo humano, posicionado longitudinalmente na fáscia do músculo quadríceps, entre os tendões quadríceps e patelar. A patela bipartida dolorosa, também conhecida como "sincrondose dolorosa", é uma causa conhecida de dor no joelho anterior, é um diagnóstico de exclusão. Objetivo: Relatar um caso e revisar a literatura acerca desta lesão incomum. Materiais e Métodos: Revisão do prontuário do paciente no Hospital Luxemburgo, registro fotográfico do método diagnóstico e revisão da literatura. Resultados: Homem de 45 anos com dor no joelho direito há 01 ano, principalmente na região anterior, que piora ao agachar. Ao exame físico apresenta edema com dor a palpação da patela. A radiografia demonstra patela bipartida. A ressonância magnética (RM) do joelho direito demonstra patela bipartida com união fibrosa entre o fragmento bipartido superolateral e a patela, associada a lesões condrais e edema subcondrais, compatível com "sincondrose dolorosa" da patela. Conclusão: Este relato demonstra a dificuldade de diagnosticar está lesão, pois seu o exame físico é inespecífico e a radiografia demonstra apenas a variação da normalidade ­ patela bipartida, sem evidenciar as alterações próprias da doença, caracterizada apenas pela RM.

The patella is the largest sesamoid bone in thehuman body, positioned longitudinally in the quadriceps muscle fascia, between the quadriceps and patellar tendons. The painful bipartite patella, also known as "painful synchondrosis", is a known cause of anterior knee pain, is a diagnosis of exclusion.Objective: Report a case and review the literature about this uncommon lesion. Materials and Methods: We carried out a review of medical records at Hospital Luxemburgo, a photographic record of diagnostic methods, and a review from the literature. Results: 45-year-old man with right knee pain for 1 year, mainly in the anterior region, which worsens when crouching. Physical examination shows edema with pain on palpation of the patella. Right knee radiography demonstrates a bipartite patella. Magnetic resonance imaging (MRI) of the right knee demonstrates a bipartite patella with a fibrous union between the superolateral bipartite fragment and the patella, associated with chondral lesions and subchondral edema, compatible with patella "painful synchondrosis". Conclusion: This report demonstrates the difficulty of diagnosing this lesion, since its physical examination is nonspecific and the radiography shows only the normal variation ­ bipartite patella, without evidencing the disease alterations, characterized only by MRI.

RESUMO

Summary Gaucher's disease is characterized by glucocerebroside accumulation in the cells of the reticuloendothelial system. There are three subtypes. The most common is type 1, known as the non-neuropathic form. Pancytopenia, hepatosplenomegaly and bone lesions occur as a result of glucocerebroside accumulation in the liver, lung, spleen and bone marrow in these patients. Findings associated with liver, spleen or bone involvement may be seen at radiological analysis. Improvement in extraskeletal system findings is seen with enzyme replacement therapy. Support therapy is added in patients developing infection, anemia or pain. We describe a case of hepatosplenomegaly, splenic infarction, splenic nodules and femur fracture determined at radiological imaging in a patient under monitoring due to Gaucher's disease.

RESUMO

Introducción: existen diferentes estudios radiológicos de rodilla en los cuales realizamos medidas que pueden orientarnos a la etiología del dolor anterior de rodilla. Nuestro objetivo fue identificar cambios morfo-radiológicos y cambios en medidas útiles en proyecciones radiográficas de rodilla de pacientes con dolor anterior de rodilla. Material y métodos: El presente es un estudio transversal en el cual se incluyó los estudios radiológicos de pacientes con dolor anterior de rodilla registrando medidas en proyecciones anteroposteriores, laterales y axiales de rótula con un posterior análisis de datos. Resultados: Entre los resultados identificamos como diagnóstico clínico más frecuente la Gonartrosis y en segundo lugar el Síndrome femoropatelar. El tipo de patela más frecuentemente encontrado fue la tipo 1. Los ángulos femoro-rotulianos fueron en su mayoría paralelos, siendo convergentes en un menor porcentaje. No existe diferencia significativa entre el tipo de patela y la lateralización rotuliana. Con un valor P de 0.820. Discusión: En base a esto podemos afirmar que el ángulo de desplazamiento de Muñoz es más útil para medir el desplazamiento rotuliano. El ángulo de congruencia de toda la población estudiada oscila entre 120° y 145°. Conclusión: No existe una diferencia significativa de lateralización rotuliana de acuerdo al ángulo de desplazamiento de Muñoz en pacientes con patela Tipo I o II. El ángulo de Muñoz es más útil que el índice de Muñoz para identificar la lateralización rotuliana. El ángulo de congruencia puede encontrarse normal incluso si existe subluxación rotuliana.

Background: there are different radiological studies of the knee in which we perform radiological measurements that can guide us to the etiology of knee pain. Our objective was to identify morpho-radiological and measure changes in radiographic knee images of patients with anterior knee pain. Methods: The present study is a cross-sectional study in which the radiological studies of patients with anterior knee pain were recorded, recording measurements on Anteroposterior, lateral and Skyline patella projection with a posterior data analysis. Results: Among the results we identi ed as the most frequent clinical diagnosis Knee osteoarthritis and in second place Patellofemoral Syndrome. The most frequently encountered type of patella was type 1. Patellofemoral angles were mostly parallel, being convergent in a lower percentage. There is no signi cant difference between the type of patella and patellar lateralization. (P value = 0.820). Discussion: Based on this, we can say that the Muñoz displacement angle is more useful for measuring patellar displacement. The congruence angle of the studied population ranges from 120° to 145°. Conclusions: We conclude that there is no signi cant difference in patellar lateralization according to the Muñoz displacement angle in patients with type I or II patella. Muñoz angle is more useful than the Muñoz index to identify patellar lateralization. The angle of congruence may be normal even if there is patellar subluxation.

RESUMO

Mobile devices, as persuasive technologies, represent an important platform to promote changes in attitudes and behaviors. They are not only understood as tools, but as a learning process that provides different opportunities to learn how to learn. The objectives of the study were to measure the quality of a virtual mobile learning object, to measure the mental workload of the educational intervention, and to evaluate the learning results. This is a technological production study with a mixed method, quasi-experimental approach. Three simulated clinical scenarios comprise the m-OVADor@, allowing for a simulated evaluation of acute pain through interactive tools. The technology met the quality criteria for educational software, with low mental workload, demonstrating a significant strategy for learning about pain among nursing students.

RESUMO

In this work, the potential of X-ray based multivariate prognostic models to predict the onset of chronic knee pain is presented. Using X-rays quantitative image assessments of joint-space-width (JSW) and paired semiquantitative central X-ray scores from the Osteoarthritis Initiative (OAI), a case-control study is presented. The pain assessments of the right knee at the baseline and the 60-month visits were used to screen for case/control subjects. Scores were analyzed at the time of pain incidence (T-0), the year prior incidence (T-1), and two years before pain incidence (T-2). Multivariate models were created by a cross validated elastic-net regularized generalized linear models feature selection tool. Univariate differences between cases and controls were reported by AUC, C-statistics, and ODDs ratios. Univariate analysis indicated that the medial osteophytes were significantly more prevalent in cases than controls: C-stat 0.62, 0.62, and 0.61, at T-0, T-1, and T-2, respectively. The multivariate JSW models significantly predicted pain: AUC = 0.695, 0.623, and 0.620, at T-0, T-1, and T-2, respectively. Semiquantitative multivariate models predicted paint with C-stat = 0.671, 0.648, and 0.645 at T-0, T-1, and T-2, respectively. Multivariate models derived from plain X-ray radiography assessments may be used to predict subjects that are at risk of developing knee pain.

RESUMO

OBJECTIVE: The study is addressed to determine if there is a correlation between intra-articular power Doppler (PD) and pain symptoms in patients with rheumatoid arthritis (RA). METHODS: A cross-sectional study of patients with established RA was rolled out. Seventy-two patients with chronic swelling at metacarpophalangeal (MCP) joints were consecutively enrolled in the study and divided into two groups (painful and painless). In the painful group, the inclusion criteria were pain in the visual analog scale (VAS), from 0 to 10 cm, of at least 4 cm and 0 in the painless group. All two to five MCP joints, bilaterally, were scanned by ultrasound (US) searching for intra-articular PD presence. Any value of p < 0.05 was considered significant. RESULTS: Patients in the painful group had longer morning stiffness, worse 28-joint disease activity score (DAS 28), and health assessment questionnaire (HAQ) indexes. There were no association between pain and gray scale (GS) synovitis, odds ratio (OR) = 0.9 (0.6-1.2), p = 0.485; and pain and intra-articular PD, OR = 0.8 (0.6-1.2), p = 0.244. CONCLUSION: Intra-articular PD was not correlated with pain symptom in this study.
