We aimed to evaluate the diagnostic accuracy of abdominal CT and pancreatic US compared to the reference standard, a modified Mayo score. Materials and Methods CT, US, and endoscopic ultrasound (EUS) were performed in patients referred due to suspected CP. The modified Mayo score included EUS results, clinical presentation, and results from exocrine and endocrine pancreatic function tests. We scored CT findings according to the modified Cambridge classification and US findings according to the Rosemont classification. Results In total, 73 patients were included. 53 patients (73%) were categorized as CP and 20 (27%) as non-CP. CT and US yielded similar sensitivities (68% and 64%, respectively) and specificities (75 and 85%, respectively) and similar areas under the receiver operating characteristic curves for diagnosing CP. We found no significant differences between the areas under the receiver operating characteristic curves (AUROCs) for CT (AUROC 0.75, 95% CI 0.63-0.87) and US (AUROC 0.81, 95% CI 0.71-0.91). Conclusion We conclude that CT and US had comparable, moderate accuracy in diagnosing CP. Neither modality had high enough sensitivity to exclude the diagnosis as a standalone method.","PeriodicalId":44852,"journal":{"name":"Ultrasound International Open","volume":"7 1","pages":"E35-E44"},"PeriodicalIF":3.2,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/0f/5c/10-1055-a-1542-9146.PMC8384479.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39358947","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}

Since they are usually found accidentally, the respective examinations have not been performed optimally to provide a conclusive diagnosis, making additional multiphase contrast-enhanced examinations necessary. The aim of the study is to correlate CEUS findings with the final diagnosis and to determine whether it is a suitable method for the conclusive characterization of undetermined renal lesions. Materials and Methods All CEUS examinations of focal renal lesions performed at our institute between 2007 and 2014 were retrospectively examined. 437 patients with a total of 491 lesions and 543 examinations were included. 54 patients had bilateral lesions. One patient had three lesions in one kidney. Histology was available in 49 cases and follow-ups in 124 cases. The sensitivity, specificity, positive and negative predictive value as well as positive and negative likelihood ratios were calculated. Results There were 54 malignant and 437 benign lesions. The sensitivity and specificity were 0.981/0.954 overall, 1.000/0.956 for cystic lesions, 0.977/0.906 for solid lesions, and 0.971/0.071 for the histologically confirmed lesions. Bosniak classification was consistent in 289 of 301 lesions (96%). Only 12 lesions (3.9%) were falsely assessed as malignant. Conclusion CEUS is an appropriate method for the clarification of undetermined renal lesions. The characterization of cystic lesions according to Bosniak is adequately possible, especially for potentially malignant lesions (types III and IV).","PeriodicalId":44852,"journal":{"name":"Ultrasound International Open","volume":"7 1","pages":"E25-E34"},"PeriodicalIF":3.2,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/14/f2/10-1055-a-1522-8969.PMC8315990.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39266763","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}

It has been evaluated in children and adults, mainly in either the obese or in subjects with suspected liver disease. Our aim was to describe CAP in healthy non-obese subjects without suspected liver steatosis and to suggest cutoff levels for steatosis. Materials and Methods We prospectively recruited 187 individuals aged 8–70 years. All underwent clinical examination, including height and weight measurement. Body mass index (BMI) was calculated and converted into z-scores. To exclude liver pathology, B-mode ultrasound and liver stiffness measurements were performed in all prior to CAP measurement. Blood was drawn for liver biochemistry in adults. Results CAP was associated with BMI z-score across all ages. CAP started to rise alongside BMI z-score already in subjects with a BMI below average. CAP values were higher in adults than in children (p<0.001), and higher in adult males than adult females (p=0.014). CAP did not correlate with age within the adult or pediatric cohorts. CAP was highly correlated with the fatty liver index. 18 and 23% of subjects showed CAP above the suggested cutoff value for children and adults, respectively. Conclusion CAP was correlated with BMI z-score, even in individuals with a below-average BMI . We found CAP above published cutoff values in a substantial proportion of presumably healthy, non-obese children and adults, warranting further research to clarify whether this represents non-obese non-alcoholic fatty liver disease or if reference values need adjustment.","PeriodicalId":44852,"journal":{"name":"Ultrasound International Open","volume":"7 1","pages":"E6-E13"},"PeriodicalIF":3.2,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/a-1461-4714","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38965219","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}

However, gastrointestinal ultrasound (GIUS), as a real-time diagnostic imaging method, can also provide information on motility, flow, perfusion, peristalsis, and organ filling and emptying, with high temporal and spatial resolution. Thanks to its noninvasiveness and high repeatability, GIUS can investigate functional gastrointestinal processes and functional gastrointestinal diseases (FGID) by studying their behavior over time and their response to therapy and providing insight into their pathophysiologic mechanisms. The European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) has established a Task Force Group consisting of GIUS experts, which developed clinical recommendations and guidelines on the role of GIUS in several acute and chronic gastrointestinal diseases. This review is dedicated to the role of GIUS in assisting the diagnosis of FGID and particularly in investigating patients with symptoms of functional disorders, such as dysphagia, reflux disorders, dyspepsia, abdominal pain, bloating, and altered bowel habits. The available scientific evidence of GIUS in detecting, assessing, and investigating FGID are reported here, while highlighting sonographic findings and its usefulness in a clinical setting, defining the actual and potential role of GIUS in the management of patients, and providing information regarding future applications and research.","PeriodicalId":44852,"journal":{"name":"Ultrasound International Open","volume":"7 1","pages":"E14-E24"},"PeriodicalIF":3.2,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/a-1474-8013","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39076888","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}

Tumors often contain more than one type of tumor cell and are called mixed germ cell tumors. The main types of non-seminoma are embryonal carcinoma, yolk sac carcinoma, choriocarcinoma, and teratoma. Other types are stromal tumors, Leydig cell tumors and Sertoli cell tumors. Secondary testicular cancers are lymphoma, leukemia, and metastases. Sarcomatoid carcinoma tumors in the testicles are very rare. Other case reports have described rare types of testicular cancer, e. g. testicular fusocellular rhabdomyosarcoma, paratesticular liposarcoma, testicular carcinoid, testicular sarcoidosis, testicular clear cell carcinoma, testicular chloroma, cutaneous mucinous carcinoma, and sarcomatoid yolk sac. When treating testicular tumors, surgery is the primary treatment and adjuvant chemotherapy and radiotherapy may be required. Owing to the aggressive nature of sarcomatoid carcinomas and the high probability of distant metastasis, the prognosis may not be favorable.

Patients and Methods The data were obtained of n=54 patients with acute, localized, peritonitic pain and EA diagnosed by B-mode ultrasound and contrast-enhanced ultrasound examination from November 2003 to September 2020. All examinations were performed by a German Society for Ultrasound in Medicine (DEGUM) Level III qualified examiner. Based on documentation by the treating physicians, the clinical awareness and acceptance of EA diagnosis was determined in all patients and compared between subgroups diagnosed before 2013 and from 2013 onwards. In 2013, a local educational training program regarding the diagnosis of and therapy for EA was initiated for physicians. Results In all patients, EA was sonographically diagnosed by a DEGUM level III qualified examiner. At enrollment, EA was mentioned as a suspected clinical diagnosis in n=1/54 (1.9%) patient. Furthermore, in n=39/54 (72.2%) cases, the EA was documented and accepted by the treating physicians at the time of patient discharge as the final clinical diagnosis. The clinical acceptance was significantly higher from 2013 onwards compared with before 2013 (p<0.05). Moreover, in n=26/54 (48.1%) patients, unnecessary therapeutic measures were initiated, with no significant difference between pre-2013 and post-2013 numbers (p>0.05). Conclusion In our retrospective study, we showed that awareness and acceptance of the disease EA are low. Low diagnostic acceptance of EA by the clinician leads to unnecessary therapeutic and imaging measures and is a general problem related to rare diseases in the healthcare system.","PeriodicalId":44852,"journal":{"name":"Ultrasound International Open","volume":"6 3","pages":"E87-E93"},"PeriodicalIF":3.2,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/a-1371-9359","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25495723","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}
