Adrenal pseudocysts are rare entities, which are usually asymptomatic. Large symptomatic adrenal pseudocysts may cause compressive symptoms. The etiology of these cysts is unknown, although the cyst wall is all lined by fibrous tissue, without any epithelial or endothelial lining. We report a case of a 26-year-old lady who presented with a symptomatic right adrenal pseudocyst measuring 7.6 cm in size. Magnetic resonance imaging confirmed the presence of a right retroperitoneal cystic lesion which was hyperintense on T2 sequencing...

Atrial fibrosis serves as an important contributor to atrial fibrillation (AF). Recent data have suggested that microRNA-30c (miR-30c) is involved in fibrotic remodelling and cancer development, but the specific role of miR-30c in atrial fibrosis remains unclear. The purpose of this study was to investigate the role of miR-30c in atrial fibrosis and its underlying mechanisms through in vivo and in vitro experiments. Our results indicate that miR-30c is significantly down-regulated in the rat abdominal aortic constriction (AAC) model and in the cellular model of fibrosis induced by transforming growth factor-β1 (TGF-β1)...

Congenital membranous occlusion of the inferior vena cava (IVC) in pediatric liver recipients may present with outflow occlusion and if unrecognized, result in graft loss. Prompt evaluation of outflow obstruction in the setting of unexplained inflow compromise is paramount. We report a case of successful IVC reconstruction in a patient with recurrent hepatic artery thrombosis (HAT). A 2-year-old child with history of two liver transplantations developed fevers, ascites, and abdominal tenderness one month after her second liver transplant...

We report the clinical case of 23-year-old patient with liver cirrhosis of unknown genesis, significant resistant ascites, and 2 episodes of bleeding from esophageal varices. Evaluation did not find any cause of liver disease, and the patient was placed on the transplant wait list due to subcompensated liver function (Model for End-Stage Liver Disease score of 16, Child-Pugh class B) and poorly controlled severe portal hypertension. After treatment with diuretics, largevolume paracentesis, antibiotics, and vasoconstrictors, hepatorenal syndrome and spontaneous bacterial peritonitis resolved and liver function improved significantly...

During pediatric kidney transplant, surgical challenges occasionally occur. In particular, vascular anastomosis should be considered for children with small body weight < 12 kg, multiple renal arteries, vascular anomaly, and inferior vena cava occlusion. In pediatric patients, a living-donor renal graft is usually donated from a parent. Therefore, the renal artery and vein are too large to be anastomosed with the recipient's internal iliac artery and external iliac vein. In children who are > 12 kg, the renal artery and vein could be anastomosed with the external iliac artery and the external iliac vein...

OBJECTIVES: Deep vein thrombosis (DVT) is a major health problem, responsible for significant morbidity and mortality. The identification of a simple and effective diagnostic biomarker of DVT remains a challenge. Metabolomics have recently emerged as a new powerful scientific tool to characterise metabolic phenotypes of complex diseases and investigate small molecules in biofluids. The aim of the study was to identify the blood and vein wall metabolomic signature of DVT in a murine experimental model...

PURPOSE: Liver segmentation from CT images is a fundamental step in trajectory planning for computer-assisted interventional surgery. In this paper, we present a fully automatic procedure using modified graph cuts and feature detection for accurate and fast liver segmentation. METHODS: The initial slice and seeds of graph cuts are automatically determined using an intensity-based method with prior position information. A contrast term based on the similarities and differences of local organs across multi-slices is proposed to enhance the weak boundaries of soft organs and to prevent over-segmentation...

BACKGROUND: Venous thromboembolism can be a significant cause of morbidity in the trauma population. Medical and surgical specialties have been pushing the indication for prophylactic filter placement. CASE DESCRIPTION: A 36-year-old man presented with axial lower back pain with a radicular right L2 component after lifting a heavy object. He had a history of penetrating brain trauma 3 years prior, with placement of a prophylactic inferior vena cava filter. His x-ray, computed tomography, and magnetic resonance imaging of the lumbar spine showed fracture of his filter, with migration of the fractured fragment through the inferior vena cava and into the L2-L3 disc space, and surrounding bony lysis and severe osteodiscitis...

INTRODUCTION: Ultrasound assessment of the inferior vena cava (IVC) has gained favour in aiding fluid management decisions for controlled, mechanically ventilated patients as well as in non-mechanically ventilated, spontaneously breathing patients. Its utility in spontaneously breathing patients during positive pressure non-invasive ventilation has not yet been determined. The use of the axillary vein, as an alternative option to the IVC due to its ease of accessibility and independence from intra-abdominal pressure, has also not been evaluated...
