Flexible Magnetoresistive Sensors for Guiding Cardiac Catheters

2018

Cardiac catheterization is a procedure, in which a long thin tube that is called a “catheter” is inserted into the heart for diagnosis or treatment. Due to the excessive use of x-ray doses and contrast agents for orientation detection during the surgery, there is a need to find a better alternative. This paper presents magnetic tunnel junction sensors on flexible Si attached to the catheter tip for orientation detection during minimally invasive surgeries. Due to the small size of catheters, extreme minimization in terms of size, weight, thickness and power consumption is needed for any device implemented on it. The fabricated flexible magnetic tunnel junctions fulfill those requirements wi…

Ventilation workshop - a new concept

2000

The use of simulator technology to practise crisis resource management or to train standardised procedures in anaesthesia is a proved concept, although its setup in clinical practice is still in progress. To get a better understanding of the complex pathophysiological and clinical relations in the pulmonary system and the kind of alterations that could be induced by changing the ventilation of an intensive care unit patient, we modified the current concept. We created a workshop, which employs more than just the simulator training in the classical sense. During this workshop the participants attend one patient from admission to an emergency room, until discharge from an intensive care unit …

Recurrent bacteraemia by 2 different Bacillus cereus strains related to 2 distinct central venous catheters.

2005

A 14-y-old girl with osteosarcoma developed 3 episodes of catheter-related bacteraemia by Bacillus cereus. After removal of the first and insertion of a second Hickman catheter, further episodes of B. cereus bacteraemia occurred. PFGE analysis revealed that bacteraemic episodes related to each catheter were caused by a distinct B. cereus strain.

Molecular typing of Agrobacterium species isolates from catheter-related bloodstream infections.

2004

AbstractAgrobacteriumisolates from intravenous catheters of three hospitalized patients were initially identified asA. tumefaciens,but inability to produce 3-ketolactose revealed that two of them wereA. vitis.However, rDNA analysis correlated all of the isolates toA. tumefaciens.Pulsed-field gel electrophoresis analysis ascertained the nosocomial transmission of the infection.

Antimicrobial consumption and antimicrobial resistance: A snapshot of an Italian neuromuscular rehabilitation center

2017

The paper presents a snapshot of the incidence of antimicrobial-resistant microorganisms and antimicrobial consumption in an Italian rehabilitation center over a two-year period (2014-2015). Data on microorganism identification and antimicrobial susceptibility testing were obtained from the diagnostic laboratory of the hospital. A set of indicators was assessed, including the incidence density of resistant isolates per 1000 patient-days (IDRI). Data on antimicrobial consumption, semi-annually, obtained from the hospital pharmacy, were expressed as Defined Daily Dose (DDD) per 1000 patient-days. The most frequently isolated microorganism was Klebsiella pneumoniae (19.3%), and a significant i…

Trends, risk factors and outcomes of health care associated infections within the Italian network SPIN-UTI

2013

Summary Background Implementing infection control measures in light of healthcare-associated infection (HAI) surveillance data can prevent HAIs. Surveillance has been associated with a reduction of HAI in intensive care unit (ICU) patients, though the reasons for this improvement remain unclear. Aim To evaluate changes in healthcare-associated infection (HAI) rates during three surveys of the Italian Nosocomial Infections Surveillance in Intensive Care Units (ICUs) network (SPIN-UTI) six-year project and to explore sources of variation of indicators of HAI in the 65 participating ICUs. Methods The SPIN-UTI network adopted the European protocols for patient-based HAI surveillance. Cumulative…

Trichosporon beigelii pneumonia in a neutropenic patient.

1989

A case of pulmonary infection caused by Trichosporon beigelii is reported in an asthmatic patient undergoing steroid treatment who developed fever and lung infiltrates. Arthroconidia and blastoconidia were isolated from repeated sputum, bronchial aspirate and telescopic catheter samples. The infection coincided with neutropenia resulting from pyrazolone treatment. The response to amphotericin B treatment was favourable.

Rifampin-impregnated silicone catheters: a potential tool for prevention and treatment of CSF shunt infections.

2003

Background: Infection continues to be one of the major complications of cerebro-spinal fluid shunting procedures. Recent insights in the pathophysiological mechanism of these foreign body infections have elucidated the difficulty of achieving successful treatment without device removal. The development of a rifampin-impregnated silicone catheter yielded excellent results in infection prevention and treatment in vitro as well as in an animal model. Patients and Methods: Here, we describe the application of this device in two patients with a complicated course of shunt infection. Results: In one patient the rifampin-impregnated shunt system was implanted after external drainage to prevent fur…
