Although this is still debatable, seronegative RA seems to be a somewhat less serious condition. The present study aimed to evaluate ankle joint ultrasound in relation to RF status and disease activity in RA patients.\u0000 \u0000 \u0000 \u0000 A cross-sectional study involving RA patients from a single center was conducted. Laboratory test evaluations and clinical activity assessments were carried out. The ankle joint was examined using musculoskeletal ultrasound (US).\u0000 \u0000 \u0000 \u0000 The study included 100 patients with established RA in total. Eighty-two patients tested positive for RF with a mean age of 42.3, whereas only 18 tested negative with a mean age of 39.6. Patients who tested positive for RF had a longer duration of illness (9.39 ± 5.39 vs. 4.56 ± 3.24). There were no differences in clinical activity scores between the seropositive and seronegative groups. The pathological US findings of any ankle joint showed no differences between the seropositive and seronegative groups. Patients with US findings of tibialis posterior tenosynovitis in the left ankle and synovitis and erosion in the right ankle, particularly in the tibiotalar and talonavicular joints, had significantly high Disease Activity Score 28-Erythrocyte sedimentation rate-scores. The increased disease activity was accompanied by significant erosions on both ankles.\u0000 \u0000 \u0000 \u0000 In terms of disease activity, there is no clinically significant difference between seropositive and seronegative RA patients. Sonographic ankle joint abnormalities do not appear to be associated with the patients’ RF status.

Chromosomal abnormalities can be diagnosed in most cases with CH, especially common trisomies and Turner syndrome. For first-trimester CH with a normal array result, management choices are limited except for waiting for serial ultrasounds to detect structural anomalies. We report two cases with a recurrent diagnosis of fetal first-trimester CH in two subsequent pregnancies. In both cases, detailed anatomic surveys in the second trimester showed structural anomalies. After excluding chromosomal abnormalities, trio-exome sequencing (ES) revealed two pathogenic variants, P3H1:c.1032T >A and c.1927_1930delinsGCTT in Case 1, and two pathogenic variants, KIAA1109:c.5788del and c. 3055C >T in Case 2. These findings were associated with two recessive genetic syndromes, osteogenesis imperfecta type VIII and Alkuraya-Kucinskas syndrome, in the two cases, respectively. Our study showed that the recurrence of fetal CH with a normal karyotype strongly indicates the existence of an autosomal recessive type of genetic disorder. For such cases, health providers should be alerted to this possibility, and early application of ES should be considered before the presentation of fetal structural anomalies which are usually present in second-trimester anatomic scans.","PeriodicalId":45466,"journal":{"name":"Journal of Medical Ultrasound","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140673886","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}

Detecting OFCs during prenatal ultrasound screening is crucial for informed decision-making and multidisciplinary medical care. This review provides a practical guide for routine and advanced screening for OFCs during mid-pregnancy. The Maarse classification system facilitates effective communication among the multidisciplinary team, categorizing OFCs into five types. Basic ultrasound views encompass coronal, sagittal, and axial imaging of the face and hard palate. Additional visualization techniques are employed in case of suspected anomalies during the initial screening. Advanced ultrasound views provided by the expert in prenatal OFC diagnosis include imaging of the posterior edge of the hard palate and the posterior part of the soft palate. Detected OFCs exhibit a range of severity and affect different structures, underscoring the importance of accurate detection and classification for appropriate treatment planning. Implementing a standardized screening protocol for OFCs is essential. By enhancing detection rates and enabling early diagnosis, prenatal ultrasound screening contributes to improved patient outcomes and facilitates timely intervention by the multidisciplinary team. In conclusion, this review emphasizes the significance of standardized protocols and specialized techniques for prenatal ultrasound screening of OFCs. Early detection and classification of these malformations play a vital role in comprehensive management, ensuring that affected individuals and their families receive the appropriate care and support they need.</p>","PeriodicalId":45466,"journal":{"name":"Journal of Medical Ultrasound","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11040495/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140857587","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}
