Purulent pericarditis has become rare since the advent of antibiotics. Among the involved germs, S. pneumoniae remains the most implicated pathogen to evoke in principle, especially that prescription of systematic antibiotics for any febrile condition can considerably mask the clinical picture. A 36-year-old pregnant woman was visiting the emergency department for dyspnea and flu-like syndrom that had been going on for a week. The chest X-ray showed a white lung on the left and the transthoracic ultrasound revealed a pericardial effusion, resulting in pericardial drainage and pleural puncture that allows the evacuation of a purulent fluid...

OBJECTIVES: Bedside ultrasound is increasingly being used to guide fluid management in shocked patients. Little data exist on the inter-rater reliability of techniques used, especially when performed by nonexpert trainee doctors. The primary aim of this study is to measure the inter-rater reliability of five ultrasound techniques commonly used to guide fluid management: inferior vena cava collapsibility index (IVCCI), transthoracic echocardiography (TTE)-derived stroke volumes, ultrasound cardiac output monitor (USCOM) derived stroke volume and carotid artery blood flow and corrected flow time measurements...

PURPOSE: Lung ultrasound is an accurate and accessible tool to quantify lung edema. Furthermore, left ventricle filling pressures (LVFP) can be assessed with transthoracic echocardiography (TTE) by the E/e' ratio (E/e'). The present study aimed to assess the correlation between E/e' and lung edema quantified by a simplified lung ultrasound score (LUS) in newly admitted septic patients. MATERIALS AND METHODS: In this prospective observational cohort, septic adult patients admitted at the emergency department of a tertiary hospital were included...

OBJECTIVE: Venous congestion is a possible mechanism leading to acute kidney injury (AKI) following cardiac surgery. Portal vein flow pulsatility is an echographic marker of cardiogenic portal hypertension and might identify clinically significant organ congestion. This exploratory study aims to assess if the presence of portal flow pulsatility measured by transthoracic echography in the postsurgical intensive care unit is associated with AKI after cardiac surgery. DESIGN: Retrospective cohort study...

Pulmonary hypertension (PH) is a disease with severe morbidity and mortality. Echocardiography plays an essential role in the screening of PH. The quality of the acquired continuous wave Doppler signal is the major limitation of the method and can greatly affect the accuracy of estimated pulmonary pressures. The aim of this study was to evaluate the clinical need to image from multiple ultrasound windows in patients with suspected pulmonary hypertension. We prospectively evaluated 65 patients (43% male, mean age 67...

Papillary fibroelastomas (PFEs) are one of the most frequent primary cardiac tumors and occur more often in patients with hypertrophic obstructive cardiomyopathy (HOCM). PFEs have been linked to an increased risk of neurological events. We report a case of a 59-year-old woman with HOCM in whom echocardiography (transthoracic and transesophageal, using 2D and 3D techniques) revealed multiple masses in various locations in the left cardiac chambers. Surgical excision of the cardiac tumors and aortic valve replacement was performed and the pathologic report confirmed the diagnosis of PFEs...

A nine-week pregnant 33-year-old female presented with sudden-onset right-sided hemiparesis, hemisensory loss, dysarthria and homonymous hemianopia. She was known to have eleven previous miscarriages and used recreational drugs. A CT-head was unremarkable. The patient was subsequently diagnosed with an acute thromboembolic infarct and chose alteplase after counselling. During thrombolysis an ultrasound identified a foetus with no concerning features.  A post-thrombolysis CT revealed a left-sided posterior cerebral infarct...

OBJECTIVES: Ultrasound (US) lung comets are often observed in patients with interstitial lung disease or congestive heart failure, but few studies have explored the clinical importance of US lung comets in patients with the former condition. We explored whether the US lung comet number could be used to assess the severity of interstitial pneumonia. METHODS: Forty stable patients with interstitial pneumonia were examined. Lung comets evident on transthoracic US imaging in 12 selected regions of the posterior chest wall were analyzed...

BACKGROUND: Although critical care ultrasound (CCUS) in the Intensive Care Unit has been increasing exponentially for diagnostic and therapeutic purposes, the lack of a uniform formal training structure and programme has posed the question of whether scans have been appropriately performed or reported, and whether there exists proper clinical governance to ensure a high standard of care. METHODS: An online survey was sent to the representatives of various national intensive care societies via the European Society of Intensive Care Medicine CoBaTrICE committee...

BACKGROUND: Ultrasound is a convenient tool to evaluate cardiac and diaphragm function. The ratio (E/Ea) of mitral Doppler inflow velocity to annular tissue Doppler wave velocity by transthoracic echocardiography (TTE) and diaphragmatic excursion (DE) by diaphragm ultrasound have been confirmed in predicting extubation outcomes independently, however their different roles in the weaning process have not been determined until now. METHODS: We designed a cohort study to preform diaphragm ultrasound and TTE before and after the spontaneous breathing trial (SBT) in difficult-to-wean patients...

BACKGROUND: Lambl's excrescences (LE) are fibrous extensions that can be found along the lines of closure of the aortic valve. Due to improvements in ultrasound technology, LE are frequently imaged during transthoracic echocardiography (TTE) in adults. OBJECTIVE: The purpose of this study was to determine the prevalence of LE among children from two eras (2004-2006 and 2011-2012) and the effect of technological advancements on LE detection. METHODS: TTE from 700 subjects (age 18 years old or younger) were reviewed...

BACKGROUND AND AIMS: Increased volume of visceral adipose tissue is associated with worsening of cardiovascular disease risk factors that contribute to aortic dilatation. We investigated the effects of visceral fat index (VFI) and VFI/percentage body fat (PBF) ratio on proximal aortic size and proximal aortic dilatation (PAD), to assess whether excess visceral fat deposition is an independent risk factor for PAD. METHODS: 738 participants aged 35 years or more were included in this cross-sectional survey...

During supramaximal exercise, exacerbated at exhaustion and in hypoxia, the circulatory system is challenged to facilitate oxygen delivery to working tissues through cerebral autoregulation which influences fatigue development and muscle performance. The aim of the study was to evaluate the effects of different levels of normobaric hypoxia on the changes in peripheral and cerebral oxygenation and performance during repeated sprints to exhaustion. Eleven recreationally active participants (six men and five women; 26...

BACKGROUND: Pulmonary embolism can be difficult to diagnose, particularly in those who are hemodynamically unstable and cannot be imaged to confirm the diagnosis. Echocardiography can allow for rapid assessment of patients in shock, but requires adequate transthoracic windows to obtain clinically useful information. Emergency physician-performed transesophageal echocardiography (TEE) may be a useful tool when transthoracic echocardiography fails. CASE REPORT: An 86-year-old woman presented to the emergency department after a fall at home...

BACKGROUND: The perioperative assessment of right ventricular (RV) function remains a challenge. Tricuspid annular plane systolic excursion (TAPSE) using M-mode is a widely used measure of RV function. However, accurate alignment of the ultrasound beam with the direction of annular movement can be difficult with transesophageal echocardiography (TEE) to measure TAPSE, precluding effective use of M-mode to measure annular excursion. Tracking of specular reflectors in the myocardium may provide an angle-independent method to assess annular motion with TEE...

BACKGROUND Bi-thalamic infarctions are rare and marked by clinical polymorphism. Their association with HIV has never been reported. CASE REPORT We report a 51-year-old right-handed man with no medical history, who presented an acute onset vascular dementia associated with an antero-retrograde amnesia, a word-finding difficulty, and a dysexecutive syndrome. The CT scan was normal. Brain MRI revealed a paramedian and bi-thalamic infarction, evoking an occlusion of the Percheron artery. The electrocardiogram, transthoracic and transesophageal cardiac ultrasound, and Doppler echo of cervical arteries gave normal results...

This case report highlights the utility of paravertebral (PV) imaging in the diagnosis of aortic dissection, the evaluation of left ventricular systolic function and drawing the distinction between pleural and pericardial effusions. In this case, less attenuation of the ultrasound beam, reduced lung viscosity due to pleural effusions and less impedance mismatch between media led to images of superior quality and high diagnostic value. This supports the use of paravertebral imaging as an adjunct to conventional echocardiography windows, particularly when conventional transthoracic imaging proves challenging...
