PATIENTS AND METHODS: Retrospective analysis of a prospectively maintained database of pelvic exenteration patients (1998-2021) was conducted in a single centre. Study outcomes included postoperative complications, quality-of-life, functional and stoma-related outcomes. The 36-item Short-Form Health Survey Physical and Mental Health Components, Functional Assessment of Cancer Therapy-Colorectal questionnaires and Distress Thermometer were available pre- and postoperatively...

A hybrid continuum robot design is introduced that combines a proximal tendon-actuated section with a distal telescoping section comprised of permanent-magnet spheres actuated using an external magnet. While, individually, each section can approach a point in its workspace from one or at most several orientations, the two-section combination possesses a dexterous workspace. The paper describes kinematic modeling of the hybrid design and provides a description of the dexterous workspace. We present experimental validation which shows that a simplified kinematic model produces tip position mean and maximum errors of 3% and 7% of total robot length, respectively...

INTRODUCTION: Peritoneal dialysis (PD)-associated peritonitis due to tuberculosis (TB) is associated with poor outcomes and optimal treatment strategies for this condition remain unknown. Our study aimed to: (i) systematically review the published literature on peritonitis caused by Mycobacterium tuberculosis in patients on PD and (ii) review cases of peritonitis due to M tuberculosis in patients on PD reported in Australia and New Zealand to determine the epidemiology, management strategies, and outcomes of this condition...

Hemodialysis catheters are frequently used for vascular access in end-stage chronic kidney disease patients lacking mature arteriovenous fistula. The incidence of infective endocarditis in hemodialysis patients is higher than in the general population and is associated with severe and potentially life-threatening complications. A high index of suspicion is imperative for early diagnosis and timely intervention to enhance the prognosis of this high-mortality condition. Imaging studies, like transthoracic and transesophageal echocardiography, are crucial for prompt diagnosis...

INTRODUCTION AND OBJECTIVES: The optimal approach for persistent atrial fibrillation (AF) ablation remains unknown. In patients with persistent AF, we compared an ablation strategy based on pulmonary vein isolation (PVI) plus ablation of drivers (PVI+D), with a conventional PVI-only approach performed in a 1:1 propensity score-matched cohort. METHODS: Drivers were subjectively identified using conventional high-density mapping catheters (IntellaMap ORION, PentaRay NAV or Advisor HD Grid), without dedicated software, as fractionated continuous or quasicontinuous electrograms on 1 to 2 adjacent bipoles, which were ablated first; and as sites with spatiotemporal dispersion (the entire cycle length comprised within the mapping catheter) plus noncontinuous fractionation, which were only targeted in patients without fractionated continuous electrograms, or without AF conversion after ablation of fractionated continuous electrograms...

OBJECTIVE: To evaluate the effectiveness of urokinase and heparin in preventing catheter infection and dysfunction in permanent hemodialysis tunneled cuffed catheters. METHODS: We randomized 153 cases of maintenance hemodialysis patients with newly implanted permanent hemodialysis tunneled cannula catheters from November 2018 to November 2021 for this single-center prospective randomized controlled trial The eligible patients were given one of two treatment plans: Patients in the control group (73 patients) were given heparin (6260 U/mL)three times a week after hemodialysis...

Background: Surgical treatment of intracranial arachnoid cysts (iACs) is challenging. Microsurgical resection, endoscopic fenestration and cysto-peritoneal shunting are the most frequently used methods, each implying their own drawbacks. Stereotactic-guided cysto-ventricular drainage has been described as an alternative method. Here we describe our experience with this technique and how we conducted volumetric measurements to evaluate the effect of permanent drainage. Methods: Standardized stereotactic planning was performed...

BACKGROUND: Persistent left superior vena cava (PLSVC) with absent right superior vena cava, also termed 'isolated PLSVC', is extremely rare. Permanent pacemaker implantation in patients with isolated PLSVC is often difficult by the usual subclavian approach due to the unique anatomy. With the advent of delivery catheters in recent years, implantation using the same system has been reported. CASE SUMMARY: A 47-year-old woman with symptomatic sick sinus syndrome was admitted to our institution for permanent pacemaker implantation...

OBJECTIVE: Treatment strategies for craniopharyngiomas are still under debate particularly for the young population. We here present tumor control and functional outcome data after surgical treatment focusing on stereotactic and microsurgical procedures for cystic craniopharyngiomas in children and adolescents. METHODS: From our prospective institutional database, we identified all consecutive patients less than 18 years of age who were surgically treated for newly-diagnosed cystic craniopharyngioma between, 2000 and, 2022...

BACKGROUND AND PURPOSE: Tumor embolization through the meningohypophyseal trunk and inferolateral trunk is known to be effective in skull-based tumors; however, microcatheter cannulation into these arteries is difficult, and the number of cases that can be safely embolized is limited. In this study, we present a novel embolization procedure for meningohypophyseal trunk and inferolateral trunk using the distal balloon protection technique and detail its clinical efficacy and complication risks...

Right bundle branch block (RBBB) and resulting RV electromechanical discoordination are thought to play a role in the disease process of subpulmonary right ventricular (RV) dysfunction that frequently occur post-repair tetralogy of Fallot. We sought to describe this disease entity, the role of pulmonary re-valvulation and the potential added value of RV cardiac resynchronization therapy (RV-CRT). Two patients with repaired tetralogy of Fallot, complete right bundle branch block, pulmonary regurgitation and significantly decreased RV function underwent echocardiography, cardiac magnetic resonance, and an invasive study to evaluate the potential for RV-CRT as part of the management strategy...

INTRODUCTION: The aim of this study was to report the long-term follow-up results of cryoballoon (CB) ablation in patients with atrial fibrillation. METHODS: All consecutive patients who underwent second-generation CB ablation from February 2015 to December 2017 were included in our study. In all procedures, we used a 28-mm CB placed via a single transseptal puncture guided by intracardiac ultrasound. A 20-mm octapolar intraluminal circular catheter was used for intracardiac recordings...

Vulvo-vaginal melanomas are one of the rarest gynecological oncology diseases with a poor survival compared with other malignancies. The 5-year survival varies from 13% to 32.3%. Vulvo-vaginal melanomas involving the upper 2/3rds of the vagina are usually treated with total pelvic exenteration (TPE). TPE surgery carries a 50% risk of major complications and also morbidity associated with double stomas. Central pelvic compartment resection is a novel organ-sparing surgical approach entailing radical total laparoscopic hysterectomy, bilateral salpingo-oophrectomy, laparoscopic vaginectomy and vulvectomy to reduce morbidity compared with TPE...

BACKGROUND AND AIMS: Although guidelines for the management of atrial fibrillation (AF) are regularly published, many controversial issues remain, limiting their implementation. We aim to describe current clinical practice among European Heart Rhythm (EHRA) community according to last guidelines. METHODS: A 30 multiple-choice questionnaire covering the most controversial topics related to AF management was distributed through the EHRA Research Network, National Societies and social media between January and February 2023...

BACKGROUND: Conduction abnormalities post transcatheter aortic valve implantation (TAVI) are common. Post-TAVI PR prolongation was mainly studied as an adjunct to new-onset bundle branch block. The net effect of isolated PR prolongation (IPRP) without post-TAVI QRS changes is not well known. AIMS: To define the incidence and clinical significance of post-TAVI IPRP. METHODS: 1108 consecutive TAVI patients were reviewed. Patients with IPRP were compared to patients without post-TAVI ECG changes...

A 41-year-old woman diagnosed with seronegative myasthenia gravis struggled to maintain remission for a decade, facing crises every 3 months for several years. After repeated apheresis using a non-tunneled non-cuffed central venous dialysis catheter (NTNCC), complications such as catheter-related thrombus in the internal jugular veins and morbid obesity from steroids made the insertion of NTNCC increasingly difficult, leading to consideration of an alternative permanent vascular access (VA) approach. Thus, we created a subcutaneously superficialized brachial artery as the VA, which allowed the patient to undergo safe and uninterrupted apheresis therapy...

INTRODUCTION: Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common supraventricular tachycardia referred for ablation. Periprocedural conduction system damage was a primary concern during AVNRT ablation. This study aimed to assess the incidence of permanent atrioventricular (AV) block and the success rate associated with different types of catheters in slow pathway ablation. METHOD: A literature search was performed to identify studies that compared various techniques, including types of radiofrequency ablation (irrigated and nonirrigated) and different sizes of catheter tip cryoablation (4, 6, and 8-mm), in terms of their outcomes related to permanent atrioventricular block and success rate...

BACKGROUND: Cavotricuspid isthmus (CTI) ablation requires permanent bidirectional block to prevent recurrence of typical atrial flutter (AFL). Catheter irrigation with half-normal saline (HNS) produces larger and deeper lesions in experimental models compared with normal saline (NS). This study was performed to compare the clinical efficacy and safety of HNS vs NS irrigation for typical AFL ablation. METHODS: Sixty patients undergoing catheter ablation of typical AFL were randomized 1:1 to NS or HNS irrigation...
