Streptococcus gordonii and related species of oral viridans group streptococci (VGS) are common etiological agents of infective endocarditis (IE). We explored vaccination as a strategy to prevent VGS- IE, using a novel antigen presenting system based on non-genetically modified Lactococcus lactis displaying vaccinogens on its surface.Hsa and PadA are surface-located S. gordonii proteins implicated in platelet adhesion and aggregation, which are key steps in the pathogenesis of IE. This function makes them ideal targets for vaccination against VGS- IE...

Atrial fibrillation is the most common arrhythmia in the United States. With the ageing population, the incidence and prevalence of atrial fibrillation are on the rise. Catheter ablation of atrial fibrillation is a widely accepted treatment modality in patients with drug refractory symptomatic paroxysmal or persistent atrial fibrillation. The close proximity to the left atrium posterior wall makes the thermosensitive esophagus a potential site of injury during catheter ablation of AF leading to various gastrointestinal complications...

PURPOSE: Over the past two decades, continuous ambulatory peritoneal dialysis has emerged as the first-choice dialysis modality in children awaiting for transplantation. Despite the improvements observed in catheter survival over the past several years, the obstruction is one of the reasons for immediate catheter non-function. This study assessed usefulness of ultrasound (US) in visualizing the obstruction of chronic peritoneal dialysis (CPD) catheter and identifying the etiology. MATERIALS AND METHODS: Between January 2000 and November 2012, 38 patients (20 M, 18 F) were treated with CPD and examined with US...

BACKGROUND: Infections are the leading cause of morbidity and mortality in patients with burns in burn units. Bloodstream infections (BSIs) in patients with burns may result from burn wound infection, use of invasive devices such as central venous catheters, and translocation of the gastrointestinal flora. OBJECTIVE: In this study, we investigated the distribution and antimicrobial drug resistance of causative pathogens in children with burns and the durational changes of microorganisms in the distribution of BSIs in children...

Catheter-related bacteremia (CRB) is an important cause of morbidity and mortality among hospitalized patients, being staphylococci the main etiologic agents. The objective of this study was to assess the use of a PCR-based assay for detection of staphylococci directly from blood obtained through the catheter to diagnose CRB caused by these microorganisms and to perform a cost-effectiveness analysis. A total of 92 patients with suspected CRB were included in the study. Samples were obtained through the catheter...

Two distinct terms are used to describe vascular thoracic outlet syndrome (TOS) depending on which structure is predominantly affected: venous TOS (due to subclavian vein compression) and arterial TOS (due to subclavian artery compression). Although the venous and arterial subtypes of TOS affect only 3% and <1% of all TOS patients respectively, the diagnostic and management approaches to venous and arterial TOS have undergone considerable evolution due to the recent emergence of minimally invasive endovascular techniques such as catheter-directed arterial and venous thrombolysis, and balloon angioplasty...

Substantiation of the shunt failure diagnosis and subsequent consideration of indications for surgical elimination of the malfunction is a laborious and challenging process. Identification of a malfunction in doubtful cases requires, in addition to standard examinations, extra diagnostic procedures, which may delay making a decision for several weeks to several months. The article describes a case of mechanical CSF shunt malfunction (breakage and failure of a peritoneal catheter in a 7-year-old girl) with intracranial hypertension symptoms, but without typical enlargement of the brain ventricles...

The use of umbilical venous catheter (UVC) is common practice in neonatal units. The traumatic injury of the hepatic parenchyma is a rare complication. We present a case of a preterm newborn underwent ultrasound examination revealing a hyperechogenic focal lesion at the confluence of the hepatic veins This finding, according to patient's history, was suspected to be a traumatic injury of the liver parenchyma caused by umbilical catheterization. During sonographic follow-up this lesion gradually reduced until complete resolution...

Vascular dysfunction at the level of the brachial artery after transradial cardiac catheterization appears transient and resolves within a week Chemo-toxicity from procedural cocktails in addition to catheter-mediated barotrauma directly to the brachial artery or indirectly from radial trauma may play a role in its etiology. Further work is needed to better define the causes of vascular damage from the transradial procedures to develop safer techniques for the future.

The external carotid artery's lingual branch to retromandibular venous fistula following a carotid endarterectomy has not been reported earlier in literature. We report a unique case of an 87-year-old man who had a right-sided carotid endarterectomy in 2009 and presented four years later with complaints of fullness and discomfort in the area of right parotid gland with associated pulsatile tinnitus. A computed tomography (CT) scan of the neck revealed a deep portion of the right parotid gland having abnormal aneurysmal dilatation of a vascular structure, which appeared to be an arteriovenous fistula between branches of right external carotid artery and the retromandibular vein...

When tinnitus is pulse-synchronous, a vascular etiology is suggested. We present a case of persistent and troublesome pulsatile tinnitus caused by a transverse-sigmoid sinus diverticulum that was endovascularly treated with stent-assisted coiling. A 39-yearold woman presented with a 4-year history of progressive pulsatile tinnitus involving the right ear. Slight pulsatile bruit was heard on the right mastoid bone by auscultation. Cerebral angiography demonstrated a diverticulum of the transverse-sigmoid sinus...
