Background: Liver transplantation (LT) is an important treatment for acute liver failure and end-stage liver disease. In 2002, the model for end-stage liver disease (MELD) score was incorporated to prioritize patients awaiting LT. Although there is data on how the MELD score affects waiting times, there is a paucity of literature regarding other components. We aimed to evaluate the factors affecting LT waiting times in the United States. Methods: Using the United Network for Organ Sharing (UNOS) database, patients aged 12-75 years listed for LT over the years 2002-2015 were included...

An aorto-cutaneous fistula is a rare complication that occurs after aortic surgery. Due to its rarity, postoperative complications are not normally highlighted in most standard teaching. We report here a case of aorto-cutaneous fistula after surgical treatment of a Stanford type A aortic dissection (AD) in a 67-year-old Chinese male. The patient presented with severe right heart dysfunction and a mass was found in the upper-middle of his chest, which started bleeding in the next years. On admission, preoperative aortic computed tomography angiography (CTA) showed a huge hematoma located in the anterior superior mediastinum and a shunt between the embedding cavity of the aortic root and right atrium...

We aimed to evaluate the outcomes of systemic-to-pulmonary (SP) shunt procedures utilizing heparin-coated (HC) polytetrafluoroethylene (PTFE) vascular grafts compared to uncoated (non-HC) grafts, in order to observe any benefits in pediatric patients. Our institution switched from using non-HC grafts to HC grafts in March 2011. We conducted a retrospective review of consecutive pediatric patients receiving SP shunts from May 2008 to December 2015. Perioperative variables including baseline characteristics, morbidity, mortality, and blood product utilization were evaluated between the HC and non-HC groups...

OBJECTIVE Patients with shunts often interact with providers distant from their primary hospital, making it important that the parent(s)/guardian(s) is well versed in the type of shunt implanted and symptoms of malfunction/infection. This is particularly important with magnetic-sensitive programmable valves, as the use of MRI becomes more prevalent. METHODS Over a 6-month period, primary caregivers of 148 consecutive patients who received shunts were prospectively administered questionnaires at clinic visits...

Phytochromes are modular bimodal photoswitches that control gene expression for morphogenetic processes in plants. These functions are triggered by the photoinduced conversions between the inactive and active states of the photosensory module, denoted as Pr and Pfr, respectively. In the present time-resolved resonance Raman spectroscopic study of bacterial representatives of this photoreceptor family, we demonstrate that these phototransformations do not represent linear processes but include a branching reaction back to the initial state, prior to (de)activation of the output module...

INTRODUCTION: There are very few reports in the literature associating in hydrocephalus in osteopetrosis. As a complication of shunt procedure, there are two reports on shunt malfunction due to osseous overgrowth at the burr hole in patients with osteopetrosis. We herein report a case of osteopetrosis with hydrocephalus that was successfully treated with endoscopic third ventriculostomy (ETV). CASE REPORT: At 5 months of age, a male patient presented with developmental delay...

OBJECTIVE: Blood blister-like aneurysms (BBAs) in the dorsal segment of the internal carotid artery (ICA) are fragile and difficult to treat, and the optimal treatment for BBAs is still controversial. We report clinical and angiographic results with procedural details for the treatment of BBA by using the endovascular patch embolization method. METHODS: We retrospectively reviewed patients who presented with subarachnoid hemorrhage(SAH) caused by ICA-BBAs and were treated with the endovascular patch embolization method in our center from October 2011 to March 2015...

BACKGROUND: Shunt nephritis is a rare, reversible immune-complex mediated complication of CSF shunt infection that can progress to end-stage renal disease and even death if diagnosis is delayed. CASE DESCRIPTION: The present case report details the manifestation and clinical course of shunt nephritis in a 50-year old patient who presented with symptoms of nephrotic syndrome 30 years after ventriculo-jugular shunt placement. Diagnosis was delayed due to initial negative CSF and blood cultures but later a CSF culture was positive for Propionibacterium acnes...

BACKGROUND: Transjugular intrahepatic portosystemic shunt (TIPS) is considered to be well suited for the treatment of noncirrhotic portal hypertension (NCPHT) because of a usually severe portal hypertension (PHT) and a mild liver failure, but very less data are available. PATIENTS AND METHODS: Records of patients referred for TIPS between 2004 and 2015 for NCPHT were reviewed. No patient should have clinical or biological or histological features of cirrhosis. RESULTS: Twenty-five patients with a wide variety of histological lesions (sinusoidal dilatations, granulomatosis, regenerative nodular hyperplasia, obliterative portal venopathy, or subnormal liver) and a wide variety of associated diseases (thrombophilia, sarcoidosis, common variable immunodeficiency, scleroderma, Castleman's disease, early primitive biliary cirrhosis, congenital liver fibrosis, chemotherapy, purinethol intake, and congenital varices) were included...

BACKGROUND: Estimation of cardiac output (CO) is essential in the treatment of circulatory unstable patients. CO measured by pulmonary artery catheter thermodilution is considered the gold standard but carries a small risk of severe complications. Stroke volume and CO can be measured by transesophageal echocardiography (TEE), which is widely used during cardiac surgery. We hypothesized that Doppler-derived CO by 3-dimensional (3D) TEE would agree well with CO measured with pulmonary artery catheter thermodilution as a reference method based on accurate measurements of the cross-sectional area of the left ventricular outflow tract...

Thoracic aortocaval fistula is a very rare cause of left to right shunt. Drainage of fistula into the superior vena cava (SVC) is very uncommon. Clinical symptoms depend on the size of the shunt. We report a rare case of an asymptomatic 27-year-old woman with congenital aortocaval fistula to the SVC with a small amount of left to right shunt that was considered for serial medical follow-up.

BACKGROUND: For intraventricular chemotherapy (IVC) as part of many oncological treatment protocols, Ommaya reservoir is enabling repeated access to the cerebro-spinal fluid (CSF). The correct placement of the catheter in the ventricle is essential for correct application of drugs, which is enabled by sophisticated techniques such as neuronavigation. OBJECTIVE: In a bi-center retrospective study, we reviewed our experience using a smartphone-assisted ventricle catheter guide as simple solution for correct Ommaya reservoir placement...

A 37-year-old man with anti-muscle-specific tyrosine kinase (MuSK) antibody-positive myasthenia gravis (MG) presented with subacute progressive dysphagia and muscle weakness of the neck and bilateral upper extremities. Conventional immune-suppressive treatments and high-dose intravenous immunoglobulin were ineffective. He then displayed repeated exacerbations and remissions over the course of two years, despite two to four sessions of plasma exchange (PE) every two months. The patient was successfully treated with outpatient periodic weekly blood purification therapy with alternative PE and double-filtration plasmapheresis using an internal shunt...
