OBJECTIVES a) To describe the introduction of noninvasive means to provide positive-pressure ventilation in acute respiratory failure; b) to describe the physiologic response to noninvasive ventilation; c) to review the current published literature on using noninvasive ventilation in patients with acute hypercapnic and/or hypoxemic respiratory failure; d) to describe the technique of applying m...

BACKGROUND Initial assessment of dyspepsia often includes noninvasive testing for Helicobacter pylori infection. Commercially available tests vary widely in cost and accuracy. Although there is extensive literature on the cost-effectiveness of H. pylori treatment, there is little information comparing the cost-effectiveness of various currently used, noninvasive testing strategies. METHODS A ...

The evaluation of graft function at various stages after transplantation is relevant, particularly at the moment of organ harvest, when a decision must be made whether to use the organ. Autofluorescence spectroscopy is noninvasive technique to monitor the metabolic condition of a liver graft throughout its course, from an initial evaluation in the donor, through cold ischemia transportation, to...

Analysis of the development of modern medical diagnosis and treatment shows that there is a worldwide trend toward introduction into medical practice of sophisticated scientifically substantiated methods minimizing invasiveness, radiation load, and other physiologically and psychologically undesirable effects. Modern electronic, laser, and computer technologies, etc. are used to increase the ef...

Background: The diagnosis and treatment of critically sick patients depend on an accurate evaluation intravascular volume status. An intrusive tool utilized for this is central venous pressure (CVP). Aim the study: In present investigation, status severely ill was evaluated using noninvasive Inferior Vena Cava (IVC) diameter Collapsibility Index (CI) measurements in ICU its link with CVP. Metho...

High Intensity Focused Ultrasound (HIFU) technique is a noninvasive medical method for localized tissue heating, used mostly in treatment of tumors. The modality of HIFU utilizes focused ultrasound to raise the temperature of the tumor tissue in small localized volumes, resulting in necrosis. The ablation of the whole tumor, while taking into consideration all safety aspects of the treatment, i...

R3F (Registre Français de la FFR) was the first study to investigate and demonstrate the clinical relevance of a new diagnostic concept based on the routine performance of fractional flow reserve (FFR) at the time of diagnostic angiography in patients suspected of coronary artery disease to define the optimal and individualized therapeutic option. The RIPCORD (Does Routine Pressure Wire Assessm...

Liver fibrosis is the main predictor of the progression of chronic hepatitis C, and its assessment by liver biopsy (LB) can help determine therapy. However, biopsy is an invasive procedure with several limitations. A new, noninvasive medical device based on transient elastography has been designed to measure liver stiffness. The aim of this study was to investigate the use of liver stiffness me...

CONTEXT The process of diagnosing temporal arteritis remains controversial. Although temporal artery biopsy has long been the standard tool of evaluation, its poor sensitivity has prompted investigation of other methods to aid in diagnosis. Improved clinical evaluation and various imaging techniques have been suggested as ways to establish the diagnosis through noninvasive means and to improve ...

A 77-year-old female presented with bilateral staghorn calculi. She underwent an uneventful left percutaneous nephrolithotomy (PCNL); the stone analysis revealed a 90% struvite and 10% calcium phosphate stone. Treatment of the right stone was postponed by the patient. During the next 9 months, her family physician gave her multiple courses of culture-directed antibiotics due to breakthrough uri...
