Rheumatoid arthritis (RA) is a chronic systemic connective tissue disease which is characterized by symetrical multiple joints involvement and extra-articular symptoms. Current EULAR diagnostic criteria for RA include disease activity parameters, such as erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), which are used to calculate disease activity scores, including DAS and DAS28. Recently attempts have been made to assess disease activity using imaging diagnostic modalities, such as magnetic resonance imaging (MRI) and ultrasonography (US). Due to significant progress in therapy effectiveness and early RA diagnosis possibility, imaging modalities become increasingly meaningful and many clinical trials confirm their usefulness. However, there are no consistent criteria for objective assessment of therapy effectiveness based on US. Moreover, it is not US availability that limits its common use, but rather significant variability between operators. This is why US remains only an additional tool to assess therapy efficacy with regard to DAS/DAS28 index.

Rheumatoid arthritis (RA) is a chronic systemic connective tissue disease. The development of comorbidities often occurs in the course of RA. One of them is osteoporosis, which has serious social and economic effects and may contribute to the increase in the degree of disability and premature death of the patient. Due to the young age in which RA disease occurs, densitometry (DXA) of the lumbar spine is the basic examination in osteoporosis diagnostics. In the course of RA, much more frequently than in healthy persons of the same age, osteoporotic fractures of vertebral bodies occur, which hinder a correct assessment in the DXA test. Rheumatoid arthritis patients often undergo computed tomography (CT) examination of the abdominal cavity for other medical indications than suspected spinal injury. Then, CT examination may also serve for the assessment of bone density, especially in patients with osteoporotic fractures.

Rheumatoid arthritis (RA) and ankylosing spondylitis (AS) are chronic progressive inflammatory diseases, leading to joint damage and reducing the physical fitness of patients. They are among the most common rheumatic diseases. However, their etiology and symptomatology are different. Formerly, AS was often wrongly diagnosed as RA. Today there are no major diagnostic difficulties in differentiation between these diseases, thanks to modern laboratory tests and imaging. However, a problem may arise when the patient has symptoms typical for both diseases simultaneously. Cases of coexistence of RA with AS – according to our best knowledge – are rare. This study aims to compare our experience in diagnosis and treatment of concomitant RA and AS with the experience of other researchers. Implementation of the proper diagnostic algorithm, allowing for correct diagnosis of both diseases in one patient, may be useful for differential diagnosis of similar cases in the future.

Rheumatoid arthritis (RA) is a chronic systemic disease of connective tissue. It is characterized by symmetrical multiple joint involvement and extra-articular symptoms. Modern RA treatment methods place a particular emphasis on the earliest possible diagnosis and initiation of appropriate treatment. Currently, ultrasonography (US) is the key imaging test performed in RA patients. However, despite the general acknowledgement of its role in the assessment of disease activity, US was not included in the applicable ACR/EULAR criteria. This is due to the lack of strictly defined criteria for US evaluation and the interpretation of test results. In addition, the absence of a correlation between the common DAS/DAS28 disease activity score and ultrasound assessment of joints makes developing new diagnostic criteria difficult. The objective of this article is to review recent scientific reports on the use of ultrasonography in the diagnosis and monitoring of RA and to indicate current problems associated with the interpretation of test results and the comparison with applicable scores of disease activity.

(1) Background: The uncinate fasciculus (UF) is a white matter bundle connecting the prefrontal cortex and temporal lobe. The functional role of the uncinate fasciculus is still uncertain. The role of the UF is attributed to the emotional empathy network. The present study aimed to more accurately the describe anatomical variability of the UF by focusing on the volume of fibers and testing for correlations with sex and age. (2) Material and Methods: Magnetic resonance imaging of adult patients with diffusion tensor imaging (DTI) was performed on 34 patients. The total number of fibers, volume of UF, and number of tracts were processed using DSI studio software. The DSI studio allows for mapping of different nerve pathways and visualizing of the obtained results using spatial graphics. (3) Results: The total number of UF tracts was significantly higher in the right hemisphere compared to the left hemisphere (right M ± SD = 52 ± 24; left: 39 ± 25, p < 0.05). A hook-shaped UF was the most common variant (91.7%). The UF volumes were larger in men (1410 ± 150.7 mm3) as compared to women (1325 ± 133.2 mm3) (p < 0.05). The mean fractional anisotropy (FA) values of the UF were significantly larger on the left side 0.597, while the right UF had an average of 0.346 (p < 0.05). Patients older than 50 years old had a significantly higher value of mean diffusivity (MD) (p = 0.034). In 73.5% of patients, a greater number of fibers terminated in the inferior part of the inferior frontal gyrus. (4) Conclusions: The morphological characteristics of the UF, unlike the shape, are associated with sex and are characterized by hemispheric dominance. These findings confirm the results of the previous studies. Future research should examine the potential correlation among the UF volume, number of fibers, and total brain volume in both sexes and patient psychological state.

ObjectiveRheumatoid arthritis (RA) is a condition that poses many diagnostic problems. As a result, it is often diagnosed too late, which makes effective treatment more difficult. The course of the disease is chronic, and it causes irreversible changes in the musculoskeletal system, as well as bone destruction, and this in turn impairs the proper monitoring of the treatment. Therefore, in order to assess the treatment’s efficacy, as well as a clinical examination of the patient and laboratory tests, diagnostic imaging is being used more frequently in routine practice. The aim of this paper is to assess the usefulness of power Doppler ultrasonography in the assessment of MCP joints in patients with chronic RA (LSRA), in comparison with DAS28, X-ray, and MRI.Material and methodsThe study involved 26 patients with LSRA, treated with biologics. It lasted for a year. At the moment of enrolment, the condition had lasted for a minimum of 5 years, and DAS28 was > 5.1. The patients had visits every three months. During every visit, a PDUS test was performed and the DAS28 was determined. In the first and last month of the study the patients underwent X-ray and MRI tests.ResultsAt the end of the study, the DAS28 of 26 (100%) patients was lower or equal to 3.2. Based on PDUS and MRI tests, no synovitis was found in 21 (81%) and 18 (69%) patients, respectively. According to the MRI results, radiological changes progressed in 5 (19%) of them. All patients who showed progress of radiological changes also had visible synovitis during their PDUS test.ConclusionsPDUS in patients with LSRA can be helpful in selecting patients, who are likely to develop a progression of radiological changes.

Słowa kluczowe: toczeń rumieniowaty układowy, tomografia komputerowa, zmiany płucne. S t r e s z c z e n i eToczeń rumieniowaty układowy (TRU) jest chorobą autoimmunologiczną prowadzącą do przewlekłego procesu zapalnego w tkankach i narządach. Wśród objawów ze strony układu oddechowego dominuje suche lub wysiękowe zapalenie opłucnej. Mogą wystąpić również zmiany śródmiąższowe, których skutki są różne w zależności od stopnia ich nasilenia. W skrajnych przypadkach mogą nawet prowadzić do śmierci. W artykule opisano trzy chore na TRU z różnym stopniem zaawansowania zmian narządowych leczone w Klinice Reumatologii. Chore w czasie procesu diagnostyczno-terapeutycznego miały m.in. wy konywane badania rentgenowskie (RTG) klatki piersiowej i tomografię komputerową wysokiej rozdzielczości (HRCT) płuc. Na podstawie wyników badań RTG klatki piersiowej u żadnej z pacjentek nie stwierdzono zmian śródmiąższowych płuc, natomiast w badaniu HRCT odnotowano także zmiany u każdej z badanych kobiet. W ocenie zmian płucnych w przebiegu TRU wykonane badanie HRCT pozwala na rozpoznanie powikłań narządowych we wczesnej fazie i zastosowanie odpowiedniego leczenia.
