Endoscopic dissection of dura and craniotomy with minimal trephines: a preliminary series.

1998

The first nine clinical cases using endoscopic dissection of dura and craniotomy with minimal trephines were performed from June to August 1997 after trial dissection of 19 fresh cadavers conducted at the University of Brno's Pathology Institute in the Czech Republic. These procedures involved the refinement of craniofacial and intracranial surgical techniques using the endoscope and prototype instruments. These dissections demonstrated that intracranial structures can be explored using an endoscope without encumbrance, and that major craniofacial surgeries may also be performed with minor incisions and minimal craniotomies. Furthermore, we seek to illustrate that use of the endoscope in cr…

Mechanism of fatal air embolism after gastrointestinal endoscopy.

1998

Although venous air embolism is a known complication in medical practice in general, only a single case of upper gastrointestinal endoscopy complicated by venous air embolism with consecutive acute cardiovascular failure has so far been described in literature. Here we show that gastroscopy may be accompanied by massive, i.e. fatal venous air embolism. If a vessel in the gastrointestinal tract is exposed but does not collapse (in the case of a gastric ulcer, for example) air insufflated under pressure by the gastroscope may lead to a fatal air embolism. Our tests using a commercial gastroscope revealed that an overpressure of up to 43 kPa (kiloPascals) is reached without the rinsing functio…

Endotracheal intubation using the C-MAC® video laryngoscope or the Macintosh laryngoscope: A prospective, comparative study in the ICU

2012

Introduction Endotracheal intubation in the ICU is a challenging procedure and is frequently associated with life-threatening complications. The aim of this study was to investigate the effect of the C-MAC® video laryngoscope on laryngeal view and intubation success compared with direct laryngoscopy. Methods In a single-center, prospective, comparative before-after study in an anesthetist-lead surgical ICU of a tertiary university hospital, predictors of potentially difficult tracheal intubation, number of intubation attempts, success rate and glottic view were evaluated during a 2-year study period (first year, Macintosh laryngoscopy (ML); second year, C-MAC®). Results A total of 274 criti…

Piecing the puzzle together: case studies of international research in health-promoting sports clubs.

2015

This paper seeks to review the current international health-promoting sports club (HPSC) research, drawing together findings based on case studies from various countries to illustrate the status of HPSCs. In addition, future challenges for HPSC research and implementation are considered. The review includes six case studies from five countries. In summary, there are two major research themes in this area, namely ‘research into HPSC activity’ and ‘research into HPSC networks’. The first theme investigates the extent to which sports clubs and/or national sports organisations invest in health promotion (HP) – both in policy and practice. The latter theme is driven by an intention to widen the…

Use of covered chimney stents for pararenal aortic pathologies is safe and feasible with excellent patency and low incidence of endoleaks.

2012

Background To present the clinical experience of consecutive series with use of balloon-expandable and self-expanding chimney endografts (balloon-expandable covered stent group [BECS] vs self-expanding covered stent group [SECS]) in the endovascular treatment of challenging aortic pathologies requiring renal and/or visceral revascularization. Methods Between January 2009 and May 2011, data for 37 high-risk patients from one center and 35 patients from another institution, with pararenal aortic pathologies treated by the chimney endovascular technique, were prospectively collected. The chimney-graft technique is based on the deployment of a covered or bare-metal stent parallel to the aortic …

CT Angiography at 24 Months Demonstrates Durability of EVAR With the Use of Chimney Grafts for Pararenal Aortic Pathologies

2013

PURPOSE: To present the 24-month radiological follow-up data for patients with pararenal aortic pathologies treated with chimney and periscope grafts during endovascular repair. METHODS: Between January 2008 and December 2011, 124 high-risk patients with complex pararenal aortic pathologies were treated using the chimney technique at 2 European vascular and cardiovascular centers with advanced experience of the described technique. In particular, 50 patients were treated at Site 1 and 74 at Site 2. Forty (32.2%) patients (32 men; mean age 79.2±4.9 years) completed computed tomographic angiography follow-up at 24 months postoperatively. RESULTS: The overall technical success was 100%, and th…

Data Reporting: Market Structures and Regulatory Framework

2020

The European legislature has identified weaknesses in the functioning and transparency of financial markets as major shortcomings of the regulatory framework under MiFID I. The new MiFID II/MiFIR regime essentially addresses these identified deficits by means of three regulatory measures: First, it considerably extends the scope and increases the stringency of the obligations with regard to pre- and post-trade transparency with a view to improving the quality of pre- and post-trade transparency data. Second, it instigates a shift towards increased trading on regulated trading venues or on other regulated platforms (more extensive market regulation and trading obligations) and, third, it ext…

Cu-substituted lanthanum ferrite perovskites: Preparation, characterization and photocatalytic activity in gas-solid regime under simulated solar lig…

2016

Lanthanum orthoferrites LaFeO3 nanopowders doped with 20 mol% of Sr and 0-10-20 mol% of Cu were prepared by citrate auto-combustion synthesis and investigated in terms of crystal structure, morphology, surface area and optical properties by using several characterization techniques. The band gap energy values were found to range from 2.35 eV for LaFeO3 to 1.86 eV for the samples with the highest content of copper, this trend reflects the decrease of the particle size. All powders showed photocurrent response, the highest photocurrent was obtained for undoped orthoferrite calcined at 600°C. Their physical-chemical properties were related to photoelectrochemical behaviour. The the position of…

Wavelength-selective directional coupling with dielectric-loaded plasmonic waveguides

2009

International audience; We consider wavelength-selective splitting of radiation using directional couplers (DCs) formed by dielectric-loaded surface-plasmon-polariton waveguides (DLSPPWs). The DCs were fabricated by depositing subwavelength-sized polymer ridges on a gold film using large-scale UV photolithography and characterized at telecommunications wavelengths with near-field microscopy. We demonstrate a DLSPPW-based 45-mu m-long DC comprising 3 mu m offset S bends and 25-mu m-long parallel waveguides that changes from the "through" state at 1500 nm to 3 dB splitting at 1600 nm, and show that a 50.5-mu m-long DC should enable complete separation of the radiation channels at 1400 and 162…
