Treatment success was defined as ≥50% improvement in the NRS score at the 6-month follow-up. Demographic, clinical, and procedural factors were analyzed.Results: The successful treatment group (n=26, 44.8%) showed significant reduction in median NRS pain scores from 7.00 to 2.00 (p<0.001) and marked improvement in ODI functional scores. Factors significantly associated with success included younger age (p=0.02), lower BMI (p<0.001), shorter symptom duration (p<0.001), nonsmoking status (p<0.001), and absence of previous spinal (p=0.03) or hip surgery (p=0.04). Early response to treatment was predictive of long-term success.Conclusion: Ultrasound-guided pulsed radiofrequency treatment provided significant pain reduction in approximately half of the patients with chronic sacroiliac joint pain at 6-month follow-up.

Traditionally, ultrasound was predominantly taught during postgraduate medical training.

Although extensive literature on individual ultrasound training programs is available, research on the effective development and implementation of ultrasound education for students remains limited. This article identified five key considerations for incorporating student ultrasound education into existing medical curricula, based on an analysis of working examples in various parts of the world: The synergistic relationship between anatomy and ultrasound, didactic evolutions such peer-assisted learning, the role of Point-of-Care-Ultrasound (POCUS) and e-Learning in resource-limited settings, the considerations of possible side effects and lastly, the early engagement with key stakeholders. These five key considerationsshould help the successful and long-term development, adaptation and implementation of a new or existing ultrasound education program in undergraduate education, thereby contributing to the training of competent future healthcare professionals.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144311126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, we conducted a subgroup analysis comparing the ultrasonographic features of gynecomastia and malignant nodules in male breasts.Results: Differences were found in age of onset, calcifications, aspect ratio greater than 1/2, Adler grading of blood flow, and axillary lymph nodes. The presence of calcifications was an independent risk factor for malignancy in males. The results of the comparison between gynecomastia and breast cancer were essentially consistent with the former. However, the differences in calcifications were not as significant as those observed in the former.Conclusions: We identified differences in age of onset, calcification, aspect ratio greater than 1/2, blood flow, and axillary lymph nodes between benign and malignant male breast nodules classified as Breast Imaging Reporting and Data System category 4, with calcification being an independent risk factor for malignancy.

An ultrasound-guided catheter-over-needle technique was proposed to reduce this risk. This study compared the incidence of vascular injections between the catheter-over-needle and Tuohy needle methods for caudal epidural injections.Material and methods: This prospective, randomized clinical trial included patients aged ≥19 years with degenerative lumbar disease accompanied by radicular pain who were unresponsive to non-invasive treatments and scheduled for caudal epidural injection. The participants were randomized into two groups: catheter-over-needle and Tuohy needle groups. Under ultrasound guidance, the contrast medium was injected and observed in real time using fluoroscopy. An independent physician assessed the vascular injection rates.Results: The incidence of vascular injection was significantly lower in the catheter-over-needle group (15.7%) than in the Tuohy needle group (37.5%; p=0.014). Chronic pain lasting >12 months was a significant risk factor for vascular injection (p=0.035). However, no statistically significant association was found between sacral opening depth and vascular injection, although the sacral opening depth was shorter in patients who received intravascular injections.Conclusions: The catheter-over-needle technique significantly reduces the risk of vascular injection. The depth of the sacral opening may also influence vascular injection.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144061253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reference points are made allowing the measurement of this sulcular space. To assess the hypothesis of normality of the data, a Kolmogorov-Smirnov test was performed for each of the samples due to the size of their population (>50). To complete this test, Lin's concordance test was also applied.Results: A total of 348 manual probing and 348 ultrasound imagines measurements were performed. The Lin concordance and correlation coefficients and their 95% confidence intervals obtained were 0.855 (95% CI [0.822; 0.855]). These data allow us to demonstrate the equivalence between the measurement of the depth of the periodontal pocket by ultrasound imaging and the measurement by manual probing.Conclusion: This study shows that the use of an ultrasound probe for periodontal imaging was comparable to the current gold standard for measuring the sulcus area.

Univariate and multivariate analyses of traditional clinical features were performed to establish a logistic regression model. Ultrasound-based radiomics features are extracted from grayscale images after delineating regions of interest (ROIs). Independent samples t-tests, Mann-Whitney U tests, and Least Absolute Shrinkage and Selection Operator (LASSO) regression were employed to select ultrasound-based radiomics features. Subsequently, five machine learning methods were used to construct radiomics models based on the selected features. Model performance was evaluated using receiver operating characteristic (ROC) curves and the Delong test.Results: Age, poorly defined margins, and irregular shape were identified as independent risk factors for malignant skin tumors. The multilayer perception (MLP) model achieved the best performance, with area under the curve (AUC) values of 0.963 and 0.912, respectively. The results of DeLong's test revealed a statistically significant discrepancy in efficacy between the MLP and clinical models (Z=2.611, p=0.009).Conclusion: Machine learning based skin tumor models may serve as a potential non-invasive method to improve diagnostic efficiency.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144002249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
