Tumours show an increased interstitial fluid pressure, which correlates with various pathophysiological features. Moreover, interstitial fluid pressure is a prognostic factor for cervical and lung cancer. However, there have been no reports on the usefulness of measuring interstitial fluid pressure in thymic epithelial tumours. Therefore, this study aimed to examine the relationship between interstitial fluid pressure and the clinicopathological characteristics of thymic epithelial tumours. Interstitial fluid pressure was prospectively measured at the centre of the tumour using a 1-Fr Mikro-Tip sensor catheter in 44 patients with thymic epithelial tumours, 40 with thymomas and 4 with thymic carcinomas...

OBJECTIVES: Inefficient aortic flow after the Norwood procedure is known to lead to the deterioration of ventricular function due to an increased cardiac workload. To prevent the progression of aortic arch obstruction, arch reconstruction concomitant with second-stage surgery is recommended. The aim of this study was to determine the indications for reconstruction based on numerical simulation and to reveal the morphology that affects the haemodynamic parameters. METHODS: Fifteen patients who underwent the Norwood procedure or arch repair and Damus-Kaye-Stansel anastomosis were enrolled...

Iatrogenic aortic dissection is an infrequent complication of cardiac catheterization (0.03-0.06%) associated with up to 19% of mortality at 30 days. It was reported to mostly occur when using a 6-Fr guiding catheter to cannulate the right coronary artery. This life-threatening complication usually requires early surgical management and close imaging monitoring and control of systolic blood pressure. This case report describes a patient with iatrogenic aortic dissection during cardiac catheterization in symptomatic coronary artery disease...

The Fontan procedure is a commonly used final pathway of palliation for single-ventricle physiology. Performing it without fenestration can avoid fenestration-related drawbacks, including subnormal oxygen saturation, decreased exercise tolerance, paradoxical embolization and subsequent need for closure by catheter intervention. If emergency fenestration is required, however, it is not always technically easy to perform, particularly when the atrium is posteriorly located and difficult to expose. We describe an easy technique for creating an anastomosis using a ring-supported polytetrafluoroethylene graft to the atrium for fenestration, performed in 2 patients who underwent extracardiac conduit Fontan procedures without fenestration...

Isolated coronary artery bypass grafting associated with atrial fibrillation is routinely performed through a sternotomy, and cardiac arrest. Advancements in this surgical approach have led to better cosmesis, a quick postoperative recovery, with the same postoperative results. We report a case of a novel, less invasive hybrid treatment combining robot-assisted coronary artery bypass grafting and percutaneous radiofrequency catheter ablation.

OBJECTIVES: Hybrid ablation of atrial fibrillation (AF) is a promising treatment strategy; however, data regarding its efficacy and safety are still limited. METHODS: Patients with non-paroxysmal AF were enrolled. First, a thoracoscopic, epicardial isolation of pulmonary veins and the left atrial posterior wall ('box lesion') was performed; a novel unipolar/bipolar radiofrequency device was used. Moreover, in 12 patients enrolled thereafter, the left atrial appendage was occluded...

Background: Approximately one quarter of all nosocomial infections can be attributed to the urinary tract. The infections are supposed to be mainly caused by implantations of urethral catheters and stents. A new catheter design is introduced with the aim to lower the high number of nosocomial urethral infections. In order to avoid limitations to use, the design is first applied to conventional commercially available balloon catheters. Results: The main feature of the design is a sandwich layer on both sides of the catheter wall, which is composed of a fragmented base layer of silver capped by a thin film of poly(p-xylylene)...

Cryoneurolysis entails using low temperatures to reversibly ablate nerves, with a subsequent analgesia duration measured in weeks or months. Previously, clinical applications for acute pain were limited because treatment originally required exposing the target nerve surgically. However, three developments have now made it possible to provide prolonged postoperative analgesia by cryoneurolysis: 1) new portable, hand-held cryoneurolysis devices, 2) ultrasound machine proliferation, and, 3) anesthesiologists trained in ultrasound-guided peripheral nerve block administration...

Smartphones and electronic tablets (e-tablets) have become ubiquitous devices. Their ease of use, smartness, accessibility, mobility and connectivity create unique opportunities to improve quality of surgical care from prehabilitation to rehabilitation. Before surgery, digital applications (Apps), serious games and text messaging may help for a better control of risk factors (hypertension, overweight), for smoking cessation, and for optimizing adherence to preoperative recommendations (e.g., regarding anticoagulation or antihypertensive treatments)...

Non-neoformans Cryptococcus species, including C. laurentii and C. albidus, have historically been classified as exclusively saprophytic. However, recent studies have increasingly implicated these organisms as the causative agent of opportunistic infections in humans. Herein, the case is presented of C. laurentii meningitis in a critically ill patient receiving corticosteroids. C. laurentii has been implicated in an additional 18 cases of opportunistic infection, predominantly of the skin, bloodstream, and central nervous system...

The stabilization of a guiding catheter is a very important factor for successful endovascular treatment. However, it is sometimes difficult to obtain sufficient stabilization because of the tortuosity of the approach route. A Goose Neck Snare is useful for the retrieval of intravascular foreign bodies and can be used to hold the guiding catheter. We describe five cases of endovascular treatment performed while using the Goose Neck Snare via the brachial artery to hold the guiding catheter. We discuss the utility of this strategy...

Cardiovascular disease (CVD) is the leading cause of increased mortality in patients with CKD and is further aggravated by peritoneal dialysis (PD). Children are devoid of preexisting CVD and provide unique insight into specific uremia- and PD-induced pathomechanisms of CVD. We obtained peritoneal specimens from children with stage 5 CKD at time of PD catheter insertion (CKD5 group), children with established PD (PD group), and age-matched nonuremic controls (n=6/group). We microdissected omental arterioles from tissue layers not directly exposed to PD fluid and used adjacent sections of four arterioles per patient for transcriptomic and proteomic analyses...

BACKGROUND & AIMS: Prevention of catheter related blood stream infections (CRBSI) and salvage of infected central venous catheters (CVC) are vital to maintaining long term venous access in patients needing home parenteral nutrition (HPN). It remains unclear as to whether patients are best trained for catheter care at home or in hospital or whether CRBSIs are lower if the patient self-cares for the CVC. Furthermore, there is minimal data on the longer term outcome following salvage of infected catheter and limited consensus on agreed protocols for catheter salvage...

BACKGROUND: Surveillance of health care-associated infections (HAIs) plays a key role in the hospital infection control program and reduction of HAIs. In India, most of the surveillance of HAIs is reported from private sector hospitals that do not depict the situation of government sector hospitals. Other studies do not confirm with the Centers for Disease Control and Prevention's (CDC) National Healthcare Safety Network (NHSN) surveillance criterion, or deal with ventilator-associated pneumonia (VAP) instead of ventilator-associated event (VAE)...

Introduction Surgically inserted rectus sheath catheters (RSCs) are used increasingly for analgesia after cystectomy and other abdominal surgery. Currently, there is little information on the optimal positioning of RSCs to allow maximal spread of local anaesthetic. This study sought to assess the spread of dye injected via RSCs and to highlight the extent of its coverage in a fresh unembalmed cadaveric cystectomy model in order to confirm the nerve endings that are likely to be anaesthetised with RSCs. Methods Four cadavers underwent lower midline incision with limited bladder mobilisation...
