Shear-Wave Elastography (SWE) has emerged as a promising non-invasive imaging technique for assessing the mechanical properties of tendons, particularly larger and more superficially located tendons of the body. Despite its potential, significant variability in SWE measurements exists due to differences in protocols, positioning, and equipment. Standardizing these factors, enhancing operator training, and reporting reliability metrics are crucial to improve the consistency and comparability of SWE data.

Adverse reactions were described in a limited number of patients and consist in local inflammatory reactions and severe acute inflammatory reactions (pseudosepsis). We present the case of a 71-year-old woman who experienced a severe acute adverse effect immediately (within minutes) following intraarticular HA administration, attributed to HA precipitation.

In addition to clinical presentation, the use of imaging techniques and confirmation of Mycobacterium tuberculosis are essential. We present the case of a 69-year-old female in whom the diagnosis of knee TB arthritis was simultaneously established with the diagnosis of MALT lymphoma.

The purpose of this study was to evaluate the effects of ankle position, probe frequency and physical effort on the shear modulus of the Achilles tendon, but also to determine the intra and inter-observer reliability of the technique.
Methods: 37 healthy volunteers were included; SWE protocol was performed by two examiners.
Aim: In rheumatoid arthritis (RA), forefoot bursitis is prevalent, with limited studies comparing ultrasonography (US) and Magnetic Resonance Imaging (MRI). This study aims to evaluate these bursae, providing a comparative analysis of US and MRI, and explore associations with demographic, disease-related factors, pain, clinical examination, and baropodometryin RA patients.
Material And Methods: Participants with RA were recruited from the day-hospital clinic.
Aim: There is no clear standardization for tendon Shear Wave Elastography (SWE), and data regarding the factors that influence the correctness of evaluation are scarce. We aimed to determine the intra- and interobserver agreement in patellar tendon SWE, and to establish the influence of various factors on elasticity values.
Materials And Methods: We recruited 37 healthy volunteers; SWE of the patellar tendon was performed by two examiners.
Introduction: Serum biomarkers are important predictive factors for development of parotid non-Hodgkin's lymphoma (NHL) complication in primary Sjogren's syndrome (pSS) patients. The aim was to evaluate the diagnostic accuracy of serum CXCL13 chemokine in pSS patients with parotid NHL complication.
Material And Methods: Serum CXCL13 chemokine was assessed in 33 patients with pSS [7 with parotid NHL complication (pSS+NHL subgroup) and 26 without NHL (pSS-NHL subgroup)] and 30 healthy subjects.
Non-Hodgkin Lymphoma (NHL) represents a severe complication and the main cause of morbidity in patients with primary Sjögren's syndrome (pSS). This study aimed to assess the role of textural analysis (TA) in revealing lymphoma-associated imaging parameters in the parotid gland (PG) parenchyma of patients with pSS. This retrospective study included a total of 36 patients (54.

The MRI examinations of 23 patients diagnosed with pSS and 23 healthy controls were retrospectively included. Texture features of both LG were extracted from a coronal post-contrast T1-weighted sequence, using a dedicated software.

We enrolled 35 rheumatoid arthritis patients and 35 healthy controls, and evaluated their ankles (tibiotalar joints, tendons), hindfeet (talonavicular, subtalar joints) and heels using clinical examination, DAS28-CRP, RAPID3 for the evaluation of functional status, quality of life in rheumatoid arthritis questionnaire, ultrasound, and baropodometry. The ultrasound inter-observer agreement was good for the subtalar joint, and very good for the other structures.

The overall classification accuracy yielded by a hybrid principal component analysis-linear discriminant analysis (PCA-LDA) model based on both SERS and elastography (81%) was superior to that yielded by SERS spectra alone (75%) and elastography data alone (71%). This preliminary study is the first report on the use of 2D-SWE of parotid glands for the diagnosis of SjS as well as the first to describe the diagnosis of SjS based on the SERS spectra of dried saliva samples, the results suggesting that the strategy of combining the two methods could improve the diagnosis of SjS.

Salivary glands ultrasound (US) is largely used, but its contribution in detecting parotid NHL has not been established. The aim of our study was to determine the added value of bidimensional shear wave elastography (2D-SWE) in pSS diagnosis and to determine its accuracy in identifying parotid NHL.

Material And Methods: RA patients were enrolled and evaluated using the Clinical Disease Activity Index (CDAI) and the Disease Activity Score 28 with C-reactive Protein (DAS28-CRP). The ankle (tibiotalar joint, tendons), hindfoot (talonavicular, subtalar joints) and heel of the most symptomatic or dominant foot (for the asymptomatic patient)were evaluated by two pairs of examiners using US and contrast-enhanced MRI.
Aim: To evaluate the ultrasound (US) modifications [grey scale, Doppler, 2D-share wave elastography (2D-SWE)] ofsalivary (parotid and submandibular) and lacrimal glands in healthy people and patients with diabetes mellitus and/or obesity, with or without sialosis.
Material And Methods: We evaluated 170 patients (1020 glands, 1700 grey scale and Doppler images), split in two groups (group 1- healthy people, group 2- obese and/or diabetes patients, with or without sialosis). For each patient we assessed the parotid, submandibular and lacrimal glands in grey scale US (echogenicity, homogeneity, glandular contour, posterior border, lymph nodes), color Doppler US and 2D-SWE.
In this preliminary study, we employed surface-enhanced Raman scattering (SERS) of saliva and serum samples for diagnosing Sjogren's syndrome (SjS), a systemic autoimmune disease characterized by dryness of the mouth and eyes. The saliva and serum samples from n = 29 patients with SjS and n = 21 controls were deproteinized with methanol and then the SERS spectra were acquired using silver nanoparticles synthesized by reduction with hydroxylamine hydrochloride. In the case of both saliva and serum, the SERS spectra were dominated by similar bands attributed to purine metabolites such as uric acid, xanthine, and hypoxanthine.
View Article and Find Full Text PDFRheumatoid arthritis (RA) is an inflammatory disease characterized by symmetrical involvement of the joints and tendons, especially of the hands and wrists, but also of the feet and ankles from the very beginning of the disease. For the patient, the foot and ankle involvement is equally important as the other joints, since it affects the functionality of the feet and the quality of life of the patients. It is already known that subclinical involvement of the ankles and feet occurs even in patients that are considered in clinical remission, thus they do not need for changes of therapy, but still might benefit from it.
