Aims: Doppler ultrasonography assessment is mandatory nowadays for the complete description of rheumatic disease activity. Initially it was performed in semi quantitative way but recently the (fully) quantitative assessment is gaining more interest. In quantitative assessment, the ratio between total colorized and total pixels (CTR) is computed for the whole image or just for the region of interest (ROI). The frame with the highest amount of Doppler signal (also called worst case scenario image – WCSI) is usually the only one analyzed. The technique requires a very precise identification of WCSI from a certain number of consecutive frames, captured from the same position of the US probe, (and in most cases this is done manually). Our study examined the ability of both experienced and in-training sonographers to identify WCSI using a computerized analytical system as the gold standard.Materials and methods: The study analyzed 480 frame selections done in two distinct exercises. The WCSI and other 3 images with a 5%, 10% and respectively 20% lower level of CTR compared with WCSI were packed in one selection. All frames emerging from the same video clip were randomly presented to six experienced and six in training sonographers; the request was to select the frame with the highest CTR (WCSI) from each package (twenty packages in total). A similar exercise was performed with CTRs decreasing in steps of 2%.Results: In the first exercise the WCSI was correctly identified in 79.1% cases and in 67% of cases in the 2nd exercise. The interobserver agreement between experienced and in-trainer evaluators for the 1st exercise was 0.78 and 0.4 in the 2nd exercise.Conclusion: Using computerized analysis as the gold standard, we demonstrated a large heterogeneity across sonographers regarding their ability to identify the best Doppler image even from a small group of frames.
Objective: The main aim of the study was to explore muscle mass changes and to investigate musculoskeletal inflammation in critically ill patients.Methods: A pure observational study that comprised two musculoskeletal analyses was conducted. Ultrasonography was used to determine the inflammatory process and muscle mass modifications. We assessed the presence of musculoskeletal inflammation and muscles area reduction. We recruited 26 patients and we performed both imaging investigations (shoulder and hip joints, biceps brachii and rectus femoris areas) and anthropometric measurements (mid-upper arm circumference).Results: More than 70% of patients were classified with low muscle mass, over one half of sarcopenic patients being over-weight and 17% being obese. The relationship between the length of stay in intensive care unit, mechanical ventilation and presence of low mid-upper arm circumference, highlighted a significant difference when comparing sarcopenic and non-sarcopenic groups. Musculoskeletal inflammation expressed by step-down lesions, calcifications and osteophytes, is common in these patients. Statistically significant results were obtained when comparing the dimensions of the investigated muscles. Good inter-observer variability in day 3 of assessment for biceps brachii and rectus femoris was noticed.Conclusions: More than 1/3 of critically ill patients included in the present study was classified with low muscle mass. The length of stay in intensive care unit and the length of mechanical ventilation had an important impact on sarcopenic patients. Musculoskeletal impairment was frequent, reflected by presence of enthesitis lesions in joints and by dynamic reduction of muscle area.
Background: The main target after successful AnteriorCruciate Ligament (ACL) reconstruction is early rehabilitation. New options such as PRP (platelet rich plasma) may improve clinical outcomes.Objective: The aim of our study was to evaluate two consecutive series of patients who underwent ACL reconstruction, one with PRP treatment and one without it.Material and method: Two groups of consecutive patients underwent arthroscopic ACL reconstruction, using the SemiT and BPTB techniques. Postoperatively all patients included in this study followed the same standardized rehabilitation protocol. In addition, patients in the first group received three intraarticular PRP injections as auxiliary therapy. Injections were performed at week two, four and six. The patients were evaluated at enrolment and every four and twelve weeks using the Tegner Lysholm Knee Scoring Scale (Scoring Scale: poor <65/ fair 65-83 / good 84-90 / excellent > 90). Each patient was operated on and evaluated afterwards by the same team of surgeons.Results: At 12 weeks interval, Group A had a higher mean clinical score than Group B (94.67 vs 92.50) although marginally not statistically significant (p=0.0503, 95% CI: −4.336 to 0.002911). Regarding pain in patients from Group A compared with patients from Group B, we saw a statistically significant difference at 4 weeks interval (16.90 vs. 18.89, p=0.0370, 95% CI: 0.1260 to 3.842) and no significant difference at 12 weeks interval (21.19 vs. 21.94, p=0.3744, 95%CI: −0.9452 to 2.453). In terms of swelling points scored between the two groups, there was no statistically significant difference at 4 week interval (5.048 vs. 4.00, p=0.1979, 95% CI: −2.667 to 0.5714) but there is a significant difference in favor of patients from Group A at 12 weeks interval (8.475 vs. 5.556, p=0.0002, 95% CI: −4.323 to −1.159).Conclusions: In the short term, the local treatment showed improvement on the overall clinical status of the patients (less pain, improved mobility, less swelling) undergoing rehabilitation after ACL reconstruction, although further studies are required.
Cystic echinococcosis is the disease that occupies, together with trichinosis, the first place in the zoonoses in Romania. We present the case of a 75-year-old urban patient known for echinococcosis, firstly operated for bone cysts in the right coxofemoral joint at the age of 24, then in 2000 she was operated for a lung hydatid cyst and in 2011 she underwent a surgery for recurrent bone echinococcosis.After a 7-year lull, she returns due to the appearance of tumorous masses in the abdominal right flank, the right thigh, accompanied by pain in the right coxofemoral joint, functional impotence of the right lower limb, asthenia, anorexia. Based on clinical, immunological, imagistic examinations, the diagnosis of cystic echinococcosis localised in the liver, bone and muscle was established. Since the patient in association had ischaemic heart disease in NYHA III (New York Heart Association) congestive heart failure, surgical treatment was delayed and preoperative treatment with Albendazole 10-15mg/kg/day was started. Initially we will apply a conservative treatment, laparoscopic drainage and aspiration of the contents, saline instillation and aspiration.
Background/Aim: Chloride intracellular channel protein 1 (CLIC1) activates inflammasomes in rheumatoid (RA) and psoriatic (PsA) arthritis. We studied CLIC1 expression in RA and PsA patients' skin with vasculitis and its variability depending on the therapy used. Materials and Methods: CLIC1 immunoexpression was evaluated in the vascular (CLIC1-V) and stromal (CLIC1-S) compartments of the RA and PsA skin biopsies of patients treated with methotrexate (MTX), leflunomid (LFN), corticotherapy (CT), or biological therapies. Results: MTX significantly reduced CLIC1-S expression (p=0.016), whereas LFN decreased CLIC1-V (p<0.001). LFN therapy duration also correlated with CLIC1-V (p<0.001). CT decreased CLIC1-S expression (p=0.006). CLIC1-S expression persisted in skin biopsies despite of erythrocyte sedimentation rate (ESR, p=0.018) and C reactive protein (CRP, p=0.0026) normalisation. For PsA, CLIC1-S expression significantly related to MTX (p<0.022). Both CLIC1-S (p<0.001) and CLIC1-V (p=0.007) decreased by biological therapies in RA. Conclusion: CLIC1 expression is strongly influenced by the therapy used. Our data strongly support the extensive evaluation of CLIC1 in RA as a potential marker of inflammation and tool to predict therapy response.Chloride intracellular channel protein 1 (CLIC1) is a member of the CLICs family, and one of the most conserved proteins (1). It was first cloned due to its increased expression in activated macrophages (2). CLIC1, also known as NCC27, has an early and variable expression in human fetal tissues, and is found in low levels in human fetal brain but in high levels in the human fetal lung, kidney, and liver (3). During human adult life, expression variability persists among most human tissues (4). The intracellular chloride channels are membrane bound and participate in different pathological processes including inflammation associated with neurodegenerative diseases (5)atherosclerosis (6) ankylosing spondylitis (7) tumor progression, and metastasis of urinary bladder cancer (8) renal cell carcinomas (9) or hepatocellular carcinomas (10). CLIC1 has a high translocation ability between the cytoplasmic and nuclear compartments depending on the functional status and based on this translocation; CLIC1 functions are extremely versatile (11). These versatile functions of chloride channels such as CLIC1 include the regulation of cellular metabolism by acting at the 2559 This article is freely accessible online.
Background: Physical rehabilitation is essential to improve the quality of life of patients with acute myocardial infarction (AMI).Study aim: The study intended to demonstrate the benefits of early rehabilitation in patients with AMI.Material and method: We performed a meta-analysis to document the benefits of physical treatment in patients who suffered an AMI. Studies were searched in the following databases: PubMed, PlosOne, Mendeley, and clinicaltrials.gov. The terms used in our research were “rehabilitation”, “physical exercise”, “physical training” “quality of life”, “early”, and “post MI”. The inclusion criteria consisted in the assessment of the following parameters: heart rate, maximal/submaximal capacity, and characteristics of the left ventricle – end-diastolic volume, ejection fraction, and left ventricle hypertrophy included in the study design.Results: The database search identified 710 studies, of which only 10 passed the inclusion criteria. Out of 1,515 patients who underwent early physical therapy, 960 reported improvement in the quality of their life (p <0.001). A number of 2,703 patients out of a total of 3,595 underwent a complete physical treatment and medication program. From the ten studies included in the meta-analysis, six had a positive feedback to the multimodal treatment within 1 month post-AMI. Patients who performed physical exercises within a month after the cardiac arrest (1,103 post-AMI patients from a total of 1,278) demonstrated a high heterogeneity represented by the coefficient I2 = 84% but with a significant statistical value of p <0.00001.Conclusion: Early physical therapy initiation significantly improves the quality of life of patients with AMI.
