Proteus mirabilis is one of the most common etiological agents of complicated urinary tract infections, especially those associated with catheterization. This is related to the ability of P. mirabilis to form biofilms on different surfaces. This pathogen encodes 17 putative fimbrial operons, the highest number found in any sequenced bacterial species so far. The present study analyzed the role of four P. mirabilis fimbriae (MR/P, UCA, ATF and PMF) in biofilm formation using isogenic mutants. Experimental approaches included migration over catheter, swimming and swarming motility, the semiquantitative assay based on adhesion and crystal violet staining, and biofilm development by immunofluorescence and confocal microscopy...

For most patients with bulky pelvic tumors, pelvic exenteration remains the only curative option. Although initially reported as a palliative procedure, nowadays it is rather performed with curative intent. Once the resectional phase is ended, a large defect will remain at the level of the pelvic diaphragm, predisposing to severe complications which are generically included under the name of empty pelvis syndrome. It has been widely demonstrated that this type of complication is associated with severe mortality, even if the patient is free of any pelvic recurrence...

BACKGROUND: Cor triatriatum is a rare congenital cardiac abnormality, consisting of an obstructing membrane between the pulmonary veins and the mitral valve in varying patterns. The entitiy can mimick the pathophysiology of mitral stenosis, necessitating surgical resection. Occasionally, percutaneous balloon dilatation of the membrane has been successfully performed. CASE PRESENTATION: We report two cases with cor triatriatum where intraoperative balloon dilatation of the membrane was attempted followed by surgical resection, to explore the feasibility of cathether-based interventional strategies for cor triatriatum...

INTRODUCTION: Vascular access is often considered the Achilles heel the of hemodialysis because of its impact on morbidity, all cause mortality and finally costs of these patients. The most common complication of permanent hemodialysis (HD) vascular access is thrombosis, with some cases being related to hypercoagulability states. Antiphospholipid antibody syndrome (APAS) is a cause of increased thrombotic tendency, and this may complicate the management of such patients on HD. CASE REPORT: We describe a 41-year-old woman with end stage renal disease (ESRD) from Adult Polycystic Kidney Disease who was referred to our tertiary care center for treatment and selection of renal replacement therapy form...

The basic form of renal replacement therapy is haemodialysis. The duration and efficacy of this treatment depends on well-functioning vascular access. Short-term or long-term catheters are used if the arterial-venous fistula placement is not possible or not indicated. According to the recommendations of the NKF DOQI (National Kidney Foundation Disease Outcomes Quality Initiative), the first choice of access is the right internal jugular vein, and the next are the left internal jugular, femoral and subclavian vein...

One factor which may be important for determining proper lesion creation in an atrial ablation procedure is catheter-endocardial contact. Little information is available that relates geometric contact, depth and angle, to ablation lesion formation. We present an electrothermal computer model of ablation that calculates lesion volume and temperature development over time. The Pennes bioheat equation was coupled to a quasistatic electrical problem. This method simulates importantly, not just catheter penetration depth, but also several different incident catheter angles as may occur in practise...

Thromboembolism is a major cause of death in cancer patients. The association between paraneoplastic hypercoagulability of oncological patients and long-term central venous catheters (CVC) may result in CVC associated thrombosis. Patent Foramen Ovale (PFO), especially when associated with atrial septal aneurysm (ASA) is a risk factor for paradoxical embolism. We report a case of paradoxical embolism with stroke in an oncological patient with a huge CVC thrombus playing "ping-pong" with an hypermobile ASA with a PFO...

BACKGROUND: Because of its technical feasibility and presumed safety benefits, balloon cryoablation is being increasingly employed for pulmonary vein (PV) isolation. While acute isolation has been demonstrated in most patients, little data are available on the chronic durability of cryoballoon lesions. METHODS AND RESULTS: Twelve atrial fibrillation patients underwent PV isolation using either a 23-mm or 28-mm cryoballoon. For each vein, after electrical isolation was verified with the use of a circular mapping cathether, 2 bonus balloon ablation lesions were placed...

Thrombotic complications in acute leukemia are often underestimated because bleeding complications generally dominate the clinical picture. While there are many thrombogenic factors shared by both solid tumors and leukemia, many additional prothrombotic features are present in leukemia. The prothrombotic factors include hyperleukocytosis, increased expression of tissue factor and its activation in leukemic cells, and the prothrombotic adverse effects of therapeutic agents and vascular access cathethers. A 18-year old woman came with swelling on her right leg 10 days before hospital admission...

Loss of luteal progesterone secretion at the end of the ovine estrous cycle is via uterine PGF(2)alpha secretion. However, uterine PGF(2)alpha secretion is not decreased during early pregnancy in ewes. Instead, the embryo imparts a resistance to PGF(2)alpha. Prostaglandins E (PGE; PGE(1)+PGE(2)) are increased in endometrium and uterine venous blood during early pregnancy in ewes to prevent luteolysis. Chronic intrauterine infusion of PGE(1) or PGE(2) prevents spontaneous or IUD, estradiol-17beta, or PGF(2)alpha-induced premature luteolysis in nonbred ewes...

Induction of mild therapeutic hypothermia early after return of spontaneous circulation improves prognosis of cardiac arrest survivors. Rapid cooling of the patients and correct maintainance of the target therapeutic temperature followed by controlled slow rewarming can be achieved by several noninvasive and invasive methods of various efficacy. Elementary and the most frequently used methods are surface cooling via ice-packs and rapid intravenous administration of cold crystaloids. Mattress cooling systems and facilities for endovascular cathether-cooling are more sophisticated, manageable and ensure more precise titration of therapeutic temperature...
