Development and validation of deep learning models for identifying the brand of pedicle screws on plain spine radiographs.

Background: In spinal revision surgery, previous pedicle screws (PS) may need to be replaced with new implants. Failure to accurately identify the brand of PS-based instrumentation preoperatively may increase the risk of perioperative complications. This study aimed to develop and validate an optimal deep learning (DL) model to identify the brand of PS-based instrumentation on plain radiographs of spine (PRS) using anteroposterior (AP) and lateral images.

Ultrasound shear wave elastography for patients with sialolithiasis undergoing interventional sialendoscopy.

Objective: Ultrasound shear wave elastography is an objective tool to evaluate the stiffness of human tissues. Patients with sialolithiasis could be treated by interventional sialendoscopy with a high success rate. Sialolithiasis could be extracted, and the diseased gland could be preserved and evaluated after treatment.

Left Ventricular Apical Aneurysm in Fabry Disease: Implications for Clinical Significance and Risk Stratification.

Background A previously underrecognized phenotype of left ventricular apical aneurysm (LVAA) has been increasingly identified in Fabry disease. This study explored LVAA's clinical prevalence and its prognostic implications over a long-term follow-up. Methods and Results We retrospectively analyzed 268 consecutive patients with Fabry disease at a tertiary medical center.

Intrathoracic myolipoma from parietal pleura with oestrogen and progesterone receptor.

Myolipoma is a rare benign lipomatous soft tissue neoplasm, occurring most frequently in adults in the abdomen, pelvis or retroperitoneum. We presented a case of a 39-year-old female with an epipleural lesion at the left paraspinal region identified using computed tomography. Magnetic resonance imaging revealed a fat-containing lesion attached to the pleura over the left paraspinal region.

Involvement of Matrix Metalloproteinase 9 in Vertebral Arterial Dissection With Posterior Circulation Ischemic Stroke.

Background Spontaneous vertebral arterial dissection (VAD) is an important cause of posterior circulation ischemic stroke (PCS), but its pathogenesis remains elusive. Matrix metalloproteinase 9 (MMP-9) is a gelatinase involved in inflammation process and several vascular diseases, such as aorta dissection, but its role in VBD is unclear yet. The present study aimed to determine the association between serum MMP-9 level and VAD-related PCS.

Cerebral Microbleed Burdens in Specific Brain Regions Are Associated With Disease Severity of Cerebral Autosomal Dominant Arteriopathy With Subcortical Infarcts and Leukoencephalopathy.

Background Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, caused by mutations, is characterized by recurrent ischemic strokes and progressive cognitive decline. It remains unclear whether cerebral microbleeds (CMBs) can serve as a surrogate marker for disease progression in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy. We aimed to investigate the CMB burdens in mutation carriers at different disease stages and test their associations with cognitive performance.

Critical airway compression caused by a large mediastinal tumour with spontaneous haemorrhage.

We report the case of a 77-year-old woman presenting with out-of-hospital cardiac arrest, which was then interpreted as an acute, life-threatening critical airway compression by a huge mediastinal tumour without appropriate diagnosis. Emergency extracorporeal membrane oxygenation was cannulated for sufficient respiratory support after spontaneous circulation was regained. After the multidisciplinary team, involving thoracic surgeons, discussed the resectability of the mediastinal tumour, the patient underwent successful resection of the mediastinal tumour through a median sternotomy.
