Systemic sclerosis (SSc) is a connective tissue disease affecting the skin and multiple organs. Most of the evidence on ocular involvement comes from small studies. We evaluated the retinal vascular changes in patients with SSc and its associations with types, disease duration, skin score, and nailfold capillaroscopy changes. We evaluated the demographic, clinical and nailfold capillaroscopy data of 52 patients referring to the clinic of scleroderma with SSc according to the 2013 ACR/EULAR SSc criteria. In addition, full ophthalmic examination in 52 patients and fundus photography in 40 patients were done in the ophthalmology clinic. There were 52 (49 women and 3 men, 17 diffuse and 35 limited) patients with SSc with mean disease duration of 8 ±5 years and mean age of 40 ±9 years. Retinal changes in the ophthalmologic examination were seen in 30.7% as increased vascular tortuosity. None of the patients had cotton wool spot, hemorrhage or hard exudate. Forty patients underwent fundus photography and 22.5% of them had vascular tortuosity. Only the presence of hemorrhage in the nailfolds was correlated with retinal tortuosity, and the other characteristics of nailfold capillaroscopy did not have any association with retinal changes. Retinal vascular changes were seen in about one third of our patients. There was no correlation between nailfold capillaroscopy, disease duration, type and skin score of SSc patients and retinal vascular changes. These findings suggest that the mechanisms or the quality of changes in the retinal vessels and nailfold vasculature may be different.Retinal vascular changes were seen in about one third of our patients.

To evaluate differences of injection related pain, and the accuracy of the techniques in two groups of overweight patients, performing the anterolateral approach for one group (G1) and the superolateral approach for the second group (G2). In the study, 126 knee joints from 86 osteoarthritis (OA) patients were evaluated. Inclusion criteria were body mass index (BMI) ≥ 25, absence of effusion and coagulopathy. Pain evaluation during injection was evaluated with Visual Analogue Scale (VAS), while accuracy of the procedure was evaluated with ultrasound (US). The patients' mean age was 69.9 ±9.01, VAS for G1 group was 1.71 ±1.89, for G2 group was 1.74 ±1.31. Mean BMI was 29.69 ±2.86, for G1 group was 28.29 ±3.29, for G2 group was 30.32 ±2.41. https://www.selleckchem.com/products/Y-27632.html No adverse events (AE) occurred in both studied groups. The accuracy rate of the procedure was 69.1% for G1 (38/55 knees), 95.7% for G2 (68/71 knees). No significant difference was found in VAS pain score between G1 and G2 group ( = 0.45). We found the significant correlation between BMI and VAS pain score in anterolateral accesses (G1) ( = 0.51; < 0.005). No correlation was found between age and VAS pain score in anterolateral access (G1). For the superolateral access (G2), no correlation was found for age or BMI and VAS pain score. Hyaluronic acid injection is safe therapeutic option for knee OA with no significant differences between anterolateral and superolateral approaches in terms of pain in overweight patients. However, higher BMI seems to be a predictor of pain in anterolateral access, and the superolateral approach should be preferred in this group of patients.Hyaluronic acid injection is safe therapeutic option for knee OA with no significant differences between anterolateral and superolateral approaches in terms of pain in overweight patients.

T-cell-mediated adaptive immunity contributes to the development and persistence of ankylosing spondylitis (AS). Mesenchymal stromal/stem cells (MSCs) have immunomodulatory potential and are able to inhibit T-cell proliferation, but their functionality in AS patients is relatively unknown. The aim of the study was to assess the direct anti-proliferative effects of MSCs isolated from subcutaneous abdominal adipose tissue of AS patients (AS/ASCs) on allogeneic T lymphocytes, using commercially available ASC lines from healthy donors (HD/ASCs) as a control. CD3+CD4+ T-cells were isolated from peripheral blood of healthy blood donors, activated with anti-CD3/CD28 beads, and co-cultured for 5 days with untreated and TNF+IFN-γ pre-stimulated HD/ASCs (5 cell lines) and AS/ASCs, obtained from 11 patients (6F/5M). The proliferative response of T-cells was analysed by flow cytometry, while the concentrations of kynurenines, prostaglandin E2 (PGE-2), interleukin 10 (IL-10), and interleukin 1 receptor antagonist (IL- contact-dependent (IL-10) and independent (kynurenines, PGE-2) pathways. Thus, our results suggest that AS/ASCs are potentially useful for therapeutic application.AS/ASCs, similar to HD/ASCs, exert a direct effective anti-proliferative impact on CD4+ T cells, acting via soluble factors that are released in cell contact-dependent (IL-10) and independent (kynurenines, PGE-2) pathways. Thus, our results suggest that AS/ASCs are potentially useful for therapeutic application. A fast and cheap method of skin assessment in systemic sclerosis (SSc) is an area of extensive research. Established in 1979, the Rodnan skin score is a palpation-based method used among clinicians. This method has some limitations, such as examiner's skills, subjective results, and no standardization. In the last few years researchers have been exploring ultrasound-based techniques as a possible tool for skin assessment among patients with SSc. The aim of the study is to develop a protocol of elastography-based skin imaging evaluation among patients with SSc. Review of the literature and own experience. Proposition of elastography-based skin imaging protocol among patients with SSc. The authors present a potential protocol of ultrasound-based examination of skin involvement among patients with SSc.The authors present a potential protocol of ultrasound-based examination of skin involvement among patients with SSc.
