The purpose of this research was to study the neutralization efficacy of a universal neutralizer proposed by the CTPA on a range of antimicrobial agents and its potential toxicity for microorganisms that are used for antimicrobial preservation testing. Several types of antimicrobial agents including a mixture of methylisothiazolinone and its 5-chloro derivative, dimethylol dimethyl hydantoin, Q...

BACKGROUND Patients with possible pulmonary embolism (PE) commonly present to acute medical services. Research has led to the identification of low-risk patients suitable for ambulatory management. We report on a protocol designed to select low-risk patients for ambulatory investigation if confirmatory imaging is not available that day. METHODS The protocol was piloted in the Emergency Depart...

introduction: capnography, is an easy, fast and practical method which its application in the diagnosis of pulmonary thromboendarterectomy (pte) has recently been studied. this study aimed to assess the diagnostic value of end-tidal co2 (etco2) and the alveolar dead space (avds) in the diagnosis of patients suspected to pte who have been referred to the emergency department. materials and metho...

Introduction Computed Tomography Pulmonary Angiography (CTPA) scans have become readily accessible in healthcare to diagnose Embolism (PE). In real-world settings, there is variability practice patterns with a growing culture of more pragmatic approach related D-dimer testing and subsequent utilisation CTPAs. However, the issue low specificity remains, risking increased unnecessary sca...

The aim of our study is to investigate prospectively the quantitative relationship between deep venous thrombosis (DVT) and acute pulmonary embolism (PE). 110 patients clinically suspected of having venous thromboembolic disease underwent combined CT pulmonary angiography (CTPA) and venography of lower limb veins. 44 patients presented with clinical signs of DVT and positive ultrasonography or ...

Although we applaud the eff ort by Koenig and colleagues 1 presented in a recent issue of CHEST (April 2014) to transmit the message that point-of-care ultrasonography may help to avoid unnecessary CT pulmonary angiography (CTPA) in patients with suspected pulmonary embolism (PE), we wish to raise a few concerns regarding the study. We believe the fact that only 12 patients (12.5%) undergoing a...

Patent foramen ovale (PFO) is a common congenital cardiac abnormality that affects one-quarter of the general population. Hypoxaemia, because large right-to-left shunt, rare complication PFO and occurs under exceptional physiological conditions. Case: This 90-year-old lady presented with progressive dyspnoea over several months. At presentation to hospital, she was hypoxaemic pO2 53 mmHg oxygen...

background: considering the importance of using more appropriate imaging technique for accurate diagnosis of pulmonary thromboembolism (pte) with less side eff ects, we aimed to evaluate the quality of pulmonary 64-multidetector computed tomographic (mdct) angiography in pregnant and postpartum women with suspected pte in isfahan. materials and methods:in this descriptive study, radiological fi...

Background: Diagnosing Pulmonary Thromboembolism (PE) remains difficult due to its non-specific symptoms and signs. There is currently no single, reliable, non-invasive diagnostic test sufficiently sensitive to consistently diagnose suspected PE. The aim of this study was to determine the sensitivity and specificity of multi-organ ultrasonography combined with clinical scores and elevated D-dim...

Diagnostic reference levels (DRLs) are an important optimisation tool, which aid in identifying abnormally high dose levels. These are currently not available in Saudi Arabia, and this research aims to remedy this. CT dose data (DLP and CTDIvol) were collected for a minimum number of 10 adult patients of average size (60-80 kg) presenting for a range of CT examinations from public hospitals in ...
