Masseter muscle thickness before and after the correction of unilateral functional posterior crossbite in growing individuals: a prospective controlled clinical trial.
Eur J Orthod
December 2024
Division of Orthodontics, University Clinics of Dental Medicine, University of Geneva, 1 rue Michel-Servet, 1205 Geneva, Switzerland.
Objectives: To evaluate whether unilateral functional posterior crossbite in growing children creates an asymmetry in masseter muscle thickness and whether this asymmetry is normalized after crossbite correction.
Materials And Methods: Two groups of growing individuals were studied prospectively: (i) a treatment group: children with unilateral functional posterior crossbite, undergoing crossbite correction with maxillary expansion; and (ii) a control group: children without transversal malocclusions and orthodontic treatment. The thickness of the masseter muscles was measured bilaterally using ultrasonographic recordings at three time points: pre-treatment (T0); 9 months after (T1); and 30 months after posterior crossbite correction (T2); and at equivalent time points in the control group.
Prenatal echocardiographic diagnosis of a discontinuous left pulmonary artery with Taussig-Bing syndrome: a case report and literature review.
Front Pediatr
December 2024
Department of Ultrasound Medicine, Taihe Hospital, Hubei University of Medicine, Shiyan, Hubei, China.
Background: Unilateral pulmonary artery discontinuity (UPAD) is a rare fetal abnormality, for which a prenatal ultrasonographic diagnosis remains challenging. We report a case of left pulmonary artery discontinuity in association with Taussig-Bing syndrome, which has rarely been reported in the literature thus far.
Case Presentation: A pregnant woman with a fetus with congenital heart disease (CHD) at 23 weeks gestation was referred to our center.
Ultrasound-based ADNEX model for differentiating between benign, borderline, and malignant epithelial ovarian tumours.

Department of Ultrasound, Clinical Oncology School of Fujian Medical University, Fujian Cancer Hospital, Fuzhou 350014, Fujian Province, China. Electronic address:
Background: The purpose of this study was to evaluate the ability of the International Ovarian Tumor Analysis-Assessment of Different NEoplasias in the adneXa (IOTA-ADNEX) model to distinguish among benign, borderline, and malignant epithelial ovarian tumours (BeEOTs, BEOTs, and MEOTs, respectively).
Methods: The study included 813 patients with BeEOTs, BEOTs, and MEOTs who underwent ultrasound examinations and pelvic operations. Comparisons were made between the clinical information and ultrasonographic features of the three patient groups, and the histopathological diagnosis was the gold standard.
Ultrasonographic modeling of lung and diaphragm mechanics: clinical trial of a novel non-invasive method to evaluate pre-operative pulmonary function.
PeerJ
December 2024
Department of Intensive Care Unit, The First Affiliated Hospital, Jiangxi Medical College, Nanchang University, Nanchang, Jiangxi, China.
Background: Pre-operative pulmonary function testing (PFT) plays a key role in predicting postoperative complications or functional impairment. However, PFT requires the subject and examiner to cooperate and the results are influenced by both technical and personal factors. In contrast, the use of ultrasound (US) for structural and functional assessments of the lungs and diaphragm is on the rise, as it requires minimal patient cooperation.

Bone or cartilage anomalies affecting the arteries supplying the brain can be a structural cause of ischemic stroke. Due to their rarity, there is currently no standardized approach for evaluating and treating these so-called bony strokes. We present a case of a 79-year-old woman with a history of cranial settling due to rheumatoid arthritis (RA) and moderate disability, who presented with insidious dizziness and gait disturbances over three weeks.
