A wide spectrum of molecules is retained in end-stage kidney disease, normally defined as uremic toxins. These solutes have different molecular weights and radii. Current dialysis membranes and techniques only remove solutes in the range of 50-15,000 Da, with limited or no capability to remove solutes in the middle to high molecular weight range (up to 50,000 Da). Improved removal has been obtained with high cut-off (HCO) membranes, with albumin loss representing a limitation to their practical application...

Hemophilia is the most common of the severe bleeding disorders and if not properly managed since early infancy can lead to chronic disease and lifelong disabilities. However, it enjoys the most efficacious and safe treatment among the most prevalent monogenic disorders. Hemophilia should be considered in the neonatal period in the case of unusual bleeding or in the case of positive family history. Later, hemophilia should be suspected mainly in males because of abnormal bruising/bleeding or unusual bleeding following invasive procedures-for example, tonsillectomy or circumcision...

Objective The efficacy of chlorhexidine- and silver sulfadiazine-coated central venous catheters (CSS-CVC) against catheter-related infection remains controversial. We hypothesized that the loss of silver nanoparticles may reduce the antibacterial efficacy of CSS-CVCs and that this loss could be due to the frictional force between the surface of the CVC and the bloodstream. The objective of this study was to investigate whether the antimicrobial effect of CSS-CVCs decreases with increasing exposure time in a bloodstream model and quantitatively assay the antimicrobial effect of CSS-CVCs compared with polyurethane and antiseptic-impregnated CVCs...

PURPOSE: In this article, we present a method for empty guiding catheter segmentation in fluoroscopic X-ray images. The guiding catheter, being a commonly visible landmark, its segmentation is an important and a difficult brick for Percutaneous Coronary Intervention (PCI) procedure modeling. METHODS: In number of clinical situations, the catheter is empty and appears as a low contrasted structure with two parallel and partially disconnected edges. To segment it, we work on the level-set scale-space of image, the min tree, to extract curve blobs...

Catheter ablation of ventricular tachycardia (VT) is an established therapy for patients with ischemic cardiomyopathy to reduce implantable cardioverter-defibrillator (ICD) interventions and is a class I recommendation in international guidelines. Numerous publications confirm its value. Use of three-dimensional mapping systems with or without image integration is standard for ablation of complex arrhythmias. In patients with history of myocardial infarction they help to understand activation of reentrant circuits and are prerequisite for substrate mapping...

Ventricular arrhythmia arising from the outflow tracts can manifest itself as frequent premature ventricular complexes (PVCs), salvos of ventricular tachycardia (VT), and/or sustained VT. It is amenable to management with medication and catheter ablation without need for an intracardiac defibrillator. The electrocardiogram (ECG) is a crucial tool in the management of these patients as it is can help localize the site of origin, thereby helping guide the electrophysiologist. An appreciation of the unique anatomy of the outflow tracts as well as their relationships with the surrounding structures is essential in interpreting the ECG...

A feared complication of ventricular access for drainage or shunting is ventriculitis. Early diagnosis and treatment is vital to prevent morbidity and mortality. Efficacy of directed antibiotic therapy in ventriculitis is limited by increasing multidrug resistant microorganisms and insufficient systemic antibiotic absorption into the cerebrospinal fluid. Treatment may involve intravenous and/or intrathecal antibiotics as well as external ventricular drainage. We present the first case report suggesting a potential role of a novel technique - direct ventricular catheter-mediated continuous saline irrigation and serial prone patient positioning - to treat a fulminant bacterial ventriculitis...

INTRODUCTION: Negative Pressure Wound Therapy (NPWT) has proven to be a powerful tool in facilitating healing of difficult wounds of a variety of etiologies. The pediatric experience with NPWT has been limited due to concerns about vascular compression and pain associated with treatment. METHOD: A retrospective review was performed to evaluate the therapeutic effect of NPWT on children with difficult wounds due to burns or soft-tissue trauma. NPWT was instituted in the operating room under general anesthesia using a commercially available system...

PURPOSE: Soft tissue sarcomas of the extremities account for half of all soft tissue sarcomas. Radiotherapy and surgery have been the standard modalities in the treatment of this type of cancer. Brachytherapy can be used as the sole therapy, if the target volume is localized and easily accessible. This work reports three cases of shoulder soft tissue sarcomas with positive deep resected margins, treated with a combination of external beam radiotherapy and surface mould brachytherapy boost technique...

PURPOSE: Salvage treatments for localized radiorecurrent prostate cancer can be performed safely when a focal and image guided approach is used. Due to the low toxicity, the opportunity exists to investigate a second salvage treatment when a second locally recurrent prostate cancer occurs. Here, we describe a second salvage treatment procedure of 4 patients. MATERIAL AND METHODS: Four patients with a pathologically proven second local recurrence were treated in an outpatient magnetic resonance imaging (MRI)-guided setting with a single fraction of 19 Gy focal high-dose-rate brachytherapy (HDR-BT)...

Inherently, brachytherapy is the most conformal radiotherapeutic technique. As an aid to brachytherapy, ultrasonography (USG) serves as a portable, inexpensive, and simple to use method allowing for accurate, reproducible, and adaptive treatments. Some newer brachytherapy planning systems have incorporated USG as the sole imaging modality. Ultrasonography has been successfully used to place applicator and dose planning for prostate, cervix, and anal canal cancers. It can guide placement of brachytherapy catheters for all other sites like breast, skin, and head and neck cancers...

Hydrocephalus is usually treated by placement of a ventriculo-peritoneal (VP) shunt. Distal VP shunt failure is a common complication of this procedure, especially in the paediatric population. Distal shunt revisions are often made more technically difficult by challenging abdominal anatomy. In this technical note, we describe a simple technique utilizing tenting sutures and the previous shunt tract for placement of the distal abdominal catheter accurately into the peritoneal space during distal shunt revision...
