The treatment of splenic injuries underwent major changes during the past decades, shifting from a surgical approach to nonoperative management. This change of the proceedings results from a constantly growing awareness of the spleen's crucial hematological and immunological function and was possible owing to the advances in radiological techniques. In a setting of high-energy trauma in hemodynamically stable patients, computed tomography (CT) remains the gold standard. Where ultrasonography (US) is of major importance is in cases of unstable patients undergone high-energy trauma or in patients after low-energy trauma. Nevertheless, baseline US's sensitivity is not sufficient to detect splenic traumatic injuries; hence, a new method was developed involving ultrasound contrast agents (UCAs), called contrast-enhanced ultrasound (CEUS). In a low-energy trauma setting, it facilitates the diagnosis of abdominal lesions with a sensitivity close to that of CT, without the disadvantages of the latter. In addition, CEUS can be used in the follow-up of abdominal traumatic injuries. The fact that CEUS preserves CT's sensitivity while not carrying the risk of radiation-induced cancer makes it feasible for children and pregnant women. This review aims to discuss the technical aspects of CEUS, the limitations, and possibilities regarding this modality, present the appearance of both a healthy and injured spleen, and compare CEUS's effectiveness to that of CT through an analysis of retrievable studies.","PeriodicalId":45466,"journal":{"name":"Journal of Medical Ultrasound","volume":"32 4","pages":"291-296"},"PeriodicalIF":0.9,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11717077/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142972704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

POCUS is often underdocumented, and therefore, underbilled, by emergency medicine physicians. The absence of POCUS documentation can result in significant revenue loss for both providers and hospital administration.Methods: This study is a follow-up study to the manuscript published by Lahham et al. and primarily examines POCUS documentation rates for a 15-month billing period following the initial intervention of a personalized e-mail reminder. Data included rates of documented and phantom scans from three separate 11-day periods (April 2019, July 2019, and July 2020) after the performance feedback intervention in March 2019.Results: Documentation rates steadily declined from April 2019 to July 2020 following the intervention, with the highest success rate being immediately after the e-mail intervention.Conclusion: This study demonstrates that there is limited durability to a single e-mail reminder as an intervention to improve POCUS documentation in the ED and suggests that there is a need for repeated interventions to prevent deterioration of documentation rates.","PeriodicalId":45466,"journal":{"name":"Journal of Medical Ultrasound","volume":"33 2","pages":"132-135"},"PeriodicalIF":0.9,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12161696/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144303237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to evaluate the association of ovarian volume and bone age measurements with the number of symptoms in female patients diagnosed with PP.Methods: The dataset includes pelvic ultrasound and bone age tests from 96 girls diagnosed with PP who presented to a tertiary hospital's pediatric outpatient clinic with signs and symptoms of early puberty between January 1, 2020, and January 1, 2021. The study included 96 healthy ladies of the same age as a control group.Results: A total volume >2.75 was shown to predict the existence of pubertal pre with 79.2% sensitivity and 90.6% specificity (area under the curve [AUC]: 0.903; P = 0.001). A total volume of >3.25 predicted the existence of 2 or more symptoms in patients with PP, with a sensitivity of 72.1% and a specificity of 98.1% (AUC: 0.917; P = 0.001).Conclusion: To the best of our knowledge, no study has been published that investigates the relationship between the number of symptoms at the time of presentation and ovarian volume and bone age in girls with PP.

Our group had published a diagnostic algorithm to identify prenatal cases, yet, the challenge continues, especially when there is no family history of a similar condition.Methods: We retrospectively analyzed our experience of prenatal diagnosis of SWS over an 8-year period with ethical approval. Literature review of articles published until July 30, 2023 from PubMed, GeneReviews, and Genetics Home Reference using search parameters, \"SWS,\" \"prenatal,\" and \"ultrasound\" was conducted.Results: Three cases (diagnosed during the routine anomaly scan) were identified from our institutional review, and 11 cases from six studies from the literature review. Eight out of these 11 cases had a positive family history. SWS was recognized without positive family history in two patients from literature review and the three patients in the current study. The consistent findings that helped in reaching the suspicion were the typical pattern of long bone involvement (bowing of tibia > femora, relative sparing of the fibula and upper limb bones, normal scapulae, and clavicles), and the presence of camptodactyly. Despite the lack of sonographic evidence of narrow thorax, SWS is highly lethal, due to dysautonomic symptoms.Conclusion: In SWS, accurate ultrasound diagnosis is crucial to provide prognostic information as the lethality does not depend on pulmonary hypoplasia. Examination of the hands looking for camptodactyly is crucial in skeletal dysplasias to distinguish SWS from other bent bone osteochondrodysplasias, namely, campomelic and kyphomelic dysplasias. This prenatal distinction has important implications for prognosis.","PeriodicalId":45466,"journal":{"name":"Journal of Medical Ultrasound","volume":"33 2","pages":"142-147"},"PeriodicalIF":0.9,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12161695/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144303245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Urethral sonography (SUG) is an able imaging modality in use for the last few years which evaluates anterior urethral stricture without these risks, though it is still not much popular due to its complexity. This prospective study was designed to compare the assessment made on SUG with the results of RGU and to analyze its impact on surgical decision-making when the results of SUG were taken into consideration with RGU.Methods: Thirty patients with anterior urethral stricture were assessed for stricture location, length, and associated urethral pathologies with RGU and surgery planned accordingly. Later, all were reevaluated with SUG, results compared with that of RGU and surgery replanned, considering both RGU and SUG findings. All results were compared with operative findings.Results: The mean stricture lengths on SUG, RGU, and surgery were 20.45 mm, 17.15 mm, and 20.38 mm, respectively. Overall sensitivity and specificity of SUG in actual stricture length prediction were 92.3% and 96.1%, whereas these were 78.9% and 85.1%, respectively, on RGU. Spongiofibrosis was assessed only with SUG, that too, with 85%-90% accuracy. Surgical plan was changed in 31% of cases when SUG findings were taken into account along with RGU findings.Conclusion: SUG was found more precise modality in the measurement of stricture length and more informative and elaborative in providing added knowledge of degree of spongiofibrosis and associated pathologies of diseased urethra and periurethral tissue. For better preoperative planning of anterior urethral strictures, SUG should be added to work-up along with RGU.","PeriodicalId":45466,"journal":{"name":"Journal of Medical Ultrasound","volume":"32 3","pages":"209-214"},"PeriodicalIF":0.9,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11414962/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142298161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
