Liquid embolic agents - Onyx as problem solver.

[Liquid embolic agents - Onyx as problem solver.] Radiologe. 2013 Feb 23; Authors: Wohlgemuth WA, Uller W, Müller-Wille R Abstract CLINICAL/METHODICAL ISSUE: Liquid embolic agents are used for permanent occlusion of capillaries but optimal administration properties are lacking. STANDARD RADIOLOGICAL METHODS: The lack of visualization by fluoroscopy and the risk of serious complications are disadvantages of conventional embolic agents, such as ethanol and Histoacryl. METHODICAL INNOVATIONS: Onyx is a liquid embolic agent consisting of ethylene vinyl alcohol copolymer dissolved in various concentrations of dimethyl sulfoxide (DMSO) and suspended micronized tantalum powder to provide contrast for fluoroscopy. PERFORMANCE: The physicochemical characteristics of Onyx allow controlled application, forming a defined cast and permanent occlusion. Disadvantages are the high costs. Furthermore, the solvent DMSO requires special catheter material and causes pain during Onyx application. ACHIEVEMENTS: Onyx has been primarily used for interventional neuroradiological treatment but peripheral applications are becoming increasingly more common. PRACTICAL RECOMMENDATIONS: Currently, Onyx is mainly used for embolotherapy of endoleaks after endovascular aortic aneurysm repair, for treatment of acute arterial bleeding and for treatment of arteriovenous malformations. ...

CONCLUSION Compared with overnight fasting, pre-operative carbohydrate loading did not significantly enhance peri-operative well being or recovery in patients undergoing day-case cholecystectomy. TRIAL REGISTRATION Clinicaltrials.gov Identifier: NCT03757208.

We reported a case of a 70-year-old female who presented to our Emergency Department (ED) with right upper quadrant pain and an initial clinical suspicion of cholecystitis. Ultrasound (US) and Computed Tomography (CT) demonstrated an anatomical variation of the sigmoid colon diverticulitis. This clinical report demonstrates that ultrasound plays a relevant part as first-step approach to the acute abdominal conditions and its accuracy increases together with other diagnostic tools such as Computer Tomography.

  Being outdoors during the warm weather season carries with it the risk of bites of all kinds – insects, animals, ticks and others. Here is some helpful advice for treating bites and itching. Check the symptoms. Most insect bites and stings are mild, causing minor symptoms like itching, redness, stinging or a small degree of swelling around the bite. In some rare cases, stings from hornets, bees, wasps, scorpions or fire ants may lead to more serious reactions, including mosquito-borne West Nile virus. The Mayo Clinic advises moving away from the area where you were stung or bitten to prevent further injur...

Discussion Restless legs syndrome (RLS) is also known as Willis-Ekbom disease. RLS is a clinical diagnosis with criteria being: 1. An urge to move the legs usually accompanied by uncomfortable and unpleasant sensations in the lower extremities (Note: sometimes other body parts can be affected) 2. The urge to move begins or worsens when sitting or lying down 3. The urge to move is partially or totally relieved by movement (Note: relief by activity may not be noticable if severely affected but must have been previously present) 4. The urge to move the legs and any accompanying unpleasant sensations during rest or in activ...

Most years I write an update on any big developments in AF ablation. This year’s version will be a short one. I have little new to report. But it’s worth reviewing some basic issues. We still do not know the cause of atrial fibrillation (AF). That makes it hard to fix with ablation. Knowledge Deficits: To explain why not knowing the cause of AF impairs our ability to ablate it, it’s useful to compare AF ablation to WPW ablation. Wolfe-Parkinson-White or WPW syndrome causes rapid heart rates because of an extra pathway from the top to the bottom (atria and ventricle) of the heart. You can cure WPW by ablat...

Scurvy is a multisystem condition that arises from vitamin C deficiency. As humans cannot synthesize vitamin C, serum and tissue levels depend on bioavailability, utilization, and renal excretion. Deficiencies result in defective collagen formation with swelling of gums, leg ulceration, and bleeding manifestations. Death most often results from infection and hemorrhage. In a forensic context, scurvy may mimic inflicted injuries and may be responsible for sudden death by mechanisms that remain unclear. Cardiac failure and rhythm disturbances with chest pain, hypotension, cardiac tamponade, and dyspnea are associated with vi...

Abstract In this editorial we comment on the article by Fukushi K et al published in the recent issue of the World Journal of Gastroenterology 2018; 24(34): 3908-3918. We focus specifically on the mechanisms of the anti-thrombotic action of aspirin, gastric mucosal injury and aging-related increased susceptibility of gastric mucosa to injury. Aspirin is widely used not only for the management of acute and chronic pain and arthritis, but also importantly for the primary and secondary prevention of cardiovascular events such as myocardial infarcts and strokes. Clinical trials have consistently shown that antiplatele...

A 52-year-old male with history of excessive alcohol use was evaluated for abdominal pain and hematochezia. Colonoscopy was only significant for a single diverticulum in the transverse colon and esophagogastroduodenoscopy was negative. Deep anterograde and spiral retrograde endoscopies also did not reveal any abnormality. Intra-operative enteroscopy showed few non-bleeding small angioectasias in the jejunum and ileum that were ligated. Despite these interventions, the patient presented again with hematochezia and epigastric pain.

​BY ARJUN BHARADWAJ; MARGARET GAVOR, MBChB, MPH; &KHALID MALIK, MDA 65-year-old man presented to the emergency department complaining of sudden-onset left-sided abdominal pain followed by a “seizure.” His abdominal pain started a few hours prior to presentation, was sharp in nature, and radiated to his back and umbilicus. The pain waxed and waned, worsened when he walked or sat up, and at its worst was a 10/10. He took a laxative and two antacids, but received no relief.Each “seizure” episode lasted about 30 seconds and occurred every five minutes. He said he felt drained after each event but ...
