The specialised conducting tissues present in the ventricles are responsible for the fast distribution of the electrical impulse from the atrio-ventricular node to regions in the subendocardial myocardium. Characterisation of anatomical features of the specialised conducting tissues in the ventricles is highly challenging, in particular its most distal section, which is connected to the working myocardium via Purkinje-myocardial junctions. The goal of this work is to characterise the architecture of the distal section of the Purkinje network by differentiating Purkinje cells from surrounding tissue, performing a segmentation of Purkinje fibres at cellular scale, and mathematically describing its morphology and interconnections...

Rectal cancer constitutes one-third of all colorectal cancers, and the incidence in Denmark increasing. In 2012, 1.400 cases were registered, and of these 38% were located in the upper rectum. There have been several key advances in the optimal management of rectal cancer during the past decades, primarily by standardisation and improvement of the surgical procedure. There is now general agreement that the optimal surgical treatment involves the concept of total mesorectal excision and that a resection with tumour-free margins is crucial...

BACKGROUND: Endovenous radio frequency ablation for small saphenous vein incompetence by and large appears to be superior and safer than conventional open surgery. Small saphenous vein ablation from approximately mid-calf to the point proximally where the small saphenous vein dives into the popliteal fossa is considered to be safe, as the sural nerve is in most cases separated from this segment of the small saphenous vein by the deep fascia. The outcome of the distal incompetent small saphenous vein remains unclear...

The aim of this study was to provide useful information about the cavotricuspid isthmus (CTI) and surrounding areas morphology, which may help to plan CTI radio-frequency ablation. We examined 140 autopsied human hearts from Caucasian individuals of both sexes (29.3% females) with a mean age of 49.1±17.2 years. We macroscopically investigated the lower part of the right atrium, the CTI, the inferior vena cava ostium and the terminal crest. The paraseptal isthmus (18.5±4.0 mm) was significantly shorter than the central isthmus (p<0...

PURPOSE: In this study, we present the clinical implementation of a novel transoral balloon centering esophageal applicator (BCEA) and the initial clinical experience in high-dose-rate (HDR) brachytherapy treatment of esophageal cancer, using this applicator. MATERIAL AND METHODS: Acceptance testing and commissioning of the BCEA were performed prior to clinical use. Full performance testing was conducted including measurements of the dimensions and the catheter diameter, evaluation of the inflatable balloon consistency, visibility of the radio-opaque markers, congruence of the markers, absolute and relative accuracy of the HDR source in the applicator using the radiochromic film and source position simulator, visibility and digitization of the applicator on the computed tomography (CT) images under the clinical conditions, and reproducibility of the offset...

The Essex Lopresti lesion is a rare triad of injury to the radial head, interosseous membrane of the forearm and distal radio-ulnar joint, which results in longitudinal instability of the radius. If unrecognized this leads to chronic pain and disability which is difficult to salvage. Early recognition and appropriate treatment is therefore desirable to prevent long-term problems. The aim of this article is to review the pathoanatomy of longitudinal radius instability and use the existing literature and authors' experience to provide recommendations for recognition and treatment of acute and chronic forearm instability, including description of the author's technique for interosseous membrane reconstruction...

OBJECTIVES: A new microfabrication method to produce low profile radio frequency (RF) resonant markers on catheter shafts was developed. A semi-active RF resonant marker incorporating a solenoid and a plate capacitor was constructed on the distal shaft of a 5 Fr guiding catheter. The resulting device can be used for interventional cardiovascular MRI procedures. MATERIALS AND METHODS: Unlike current semi-active device visualization techniques that require rigid and bulky analog circuit components (capacitor and solenoid), we fabricated a low profile RF resonant marker directly on guiding the catheter surface by thin film metal deposition and electroplating processes using a modified physical vapor deposition system...

The fracture of the upper end of the humerus is the third most frequent fracture in the elderly and its distribution is bimodal, preferentially affecting osteoporotic elderly patients after low energy trauma or, more rarely, young subjects as a consequence of severe kinetic mechanism The treatment of complex fractures of the proximal humerus is the subject of much controversy. Telegraph nail is a highly effective therapeutic approach for displaced fractures of the upper end of the humerus. Surgical procedure is easy but with a learning curve; it allows to start rehabilitation protocol immediately after surgery...

Distal radio-cephalic arteriovenous fistula is the 'gold standard' vascular access for chronic hemodialysis. Its main drawback is early failure, which can complicate up to 50 % of this surgical procedure. Two scenarios of failure are possible: early post-operative thrombosis or impaired maturation. The first is mainly due to a defective preoperative evaluation or poor surgical procedure. The latter is a patent angioaccess unable to deliver adequately hemodialysis due to a persistently low blood flow or difficult cannulation...

INTRODUCTION: Gastrocnemius muscle is a workhorse flap to cover upper third tibial defects but has a limitation in covering middle one-third tibial defects. The inferiorly based hemi gastrocnemius muscle flap can be useful for reconstruction of the middle third of the leg. The arterial communication between the gastrocnemius muscle heads has been demonstrated, the consistent location, however, was not studied in large specimens. MATERIALS AND METHODS: This study was conducted on sixty specimens of gastrocnemius muscles harvested from thirty fresh cadavers to determine arterial communication between two heads of gastrocnemius muscle using radio-opaque contrast with future application of taking one head of muscle distally based for coverage of middle third defect of tibia...

The main function of the forearm is the supination, which is achieved largely through the biomechanical characteristics and stability of the distal radio-ulnar joint. There are several surgical techniques for the treatment of distal radio-ulnar dislocations isolated or associated with a fracture. We report the case of a canine trainer who was bitten at the wrist and distal forearm that came to the emergency department in where distal ulnar dislocation with muscle tendon exposure was diagnosed. Due to the offending agent and multiple soft tissue injuries the treatment with standard techniques was impossible...

PURPOSE: Lymph outflow from bladder tumor differs between individuals, making the prediction of the metastatic landing sites difficult. A "blind" template of lymphadenectomy has been tested as a solution to this problem. We believe that it is feasible to find methods enabling more precise lymph nodes (LNs) evaluation. The aims of our study were to evaluate the possibility of LNs mapping in case of muscle invasive bladder cancer (MIBC) and to compare the 2 methods of their detection. PATIENTS AND METHODS: Our study group consisted of 38 cN0 MIBC patients...
