The Impact of Different Lung Ultrasound Protocols in the Assessment of Lung Lesions in COVID-19 Patients: Is There an Ideal Lung Ultrasound Protocol?

Background: In the past months, several lung ultrasonography (LUS) protocols have been proposed, mainly on previously validated schemes independent of coronavirus disease 2019 (COVID-19).

Objectives: The main purpose of this study was to determine the impact and accuracy of different LUS protocols proposed in COVID-19.

Methods: Patients were evaluated with a standard sequence of LUS scans in 72 intercostal spaces along 14 anatomic lines in the chest.

Usefulness of Lung Ultrasound Follow-up in Patients Who Have Recovered From Coronavirus Disease 2019.

Coronavirus disease 2019 is caused by severe acute respiratory syndrome coronavirus 2 infection, which tends to be mild. Even in these cases, our understanding is still incomplete, particularly regarding its sequelae and long-term outcomes. We describe 3 recovered patients who had coronavirus disease 2019, with long-persisting symptoms after recovery, in whom chest computed tomographic and concurrent lung ultrasound examinations were performed.

Correlation between Chest Computed Tomography and Lung Ultrasonography in Patients with Coronavirus Disease 2019 (COVID-19).

There is growing evidence regarding chest X-ray and computed tomography (CT) findings for coronavirus disease 2019 (COVID-19). At present, the role of lung ultrasonography (LUS) has yet to be explored. The main purpose of this study was to evaluate the correlation between LUS findings and chest CT in patients confirmed to have (positive reverse transcription polymerase chain reaction [RT-PCR]) or clinically highly suspected of having (dyspnea, fever, myasthenia, gastrointestinal symptoms, dry cough, ageusia or anosmia) COVID-19.

A Cohort of Patients with COVID-19 in a Major Teaching Hospital in Europe.

Background: Since the confirmation of the first patient infected with SARS-CoV-2 in Spain in January 2020, the epidemic has grown rapidly, with the greatest impact on the region of Madrid. This article describes the first 2226 adult patients with COVID-19, consecutively admitted to La Paz University Hospital in Madrid.

Methods: Our cohort included all patients consecutively hospitalized who had a final outcome (death or discharge) in a 1286-bed hospital of Madrid (Spain) from 25 February (first case admitted) to 19 April 2020.

Acute complications and outcomes of acute head injury in adult patients with haemophilia.

The aim of the present study is to describe the clinical and epidemiological characteristics, complications and outcome of patients with haemophilia and acute head injury (AHI) at the emergency department (ED), and develop a protocol to prevent early and late complications. This is a retrospective cohort study including all patients with haemophilia and AHI admitted to the ED. We identified 26 patients with AHI.

[Use of multidetector computed tomography for locating the site of gastrointestinal tract perforations].

Introduction: The purpose of this study was to evaluate the accuracy of multidetector computed tomography (MDCT) for locating the site of gastrointestinal tract perforations and to determine the most predictive signs in this diagnosis.

Material And Methods: A total of 98 patients with pneumoperitoneum on MDCT were retrospectively analysed. Two experienced radiologists reviewed the presence or absence of direct signs (extravasation of oral contrast, focal defect in the bowel wall, focal defect with multiplanar reformations images) and indirect signs (free air in supramesocolic, inframesocolic, supramesocolic and inframesocolic compartments, concentration of extraluminal air bubbles adjacent to the bowel wall, extraluminal fluid, segmental bowel-wall thickening, perivisceral fat stranding, abscess) to identify the site of the perforation.

Radiological prognostic factors in patients with pandemic H1N1 (pH1N1) infection requiring hospital admission.

The aim of this study was to determine the radiologic findings associated with admission to the intensive care unit (ICU) and the development of acute respiratory distress syndrome (ARDS) in patients with pH1N1 infection. One hundred and four patients (15-96 years) with laboratory-confirmed pH1N1 infection seen at the Emergency Department from July to December 2009 who underwent chest radiographs were studied. Radiographs were evaluated for consolidation, ground-glass opacities, interstitial patterns, distribution, and extent of findings.

[Acute massive pulmonary embolism with thrombus entrapped in patent foramen ovale].

Thromboembolic disease is a potentially severe pathology, which can represent a life threat if it is not diagnosed early, especially when the cardiopulmonary backup is limited. When its clinical feature implies a massive occlusion of the arterial pulmonary tree and a cardiac failure is ensued, it can be seriously life threatening, even for young patients. Less frequent features as right or left atrium thrombosis could increase de morbidity and mortality of this disease.

Trapped on the "whirl": diagnostic sign on emergency CT.

The "whirl sign" is an uncommon finding on emergency CT. However, it is easy to overlook if not kept in mind. Its recognition is of capital importance, being most of its causes potentially lethal.

Subcutaneous emphysema: diagnostic clue in the emergency room.

The objective of this study was to illustrate the wide spectrum of subcutaneous emphysema in the emergency room; to show the key findings on computed tomography, plain radiographs, and echography; and to discuss the differential diagnoses. Subcutaneous emphysema is a common finding in emergency department imaging studies. It has a great importance due to its broad casualty, some of them totally benign, but others potentially lethal.

Correlation between the measurement of transverse diameter in the proximal neck on computed tomography and on aortography before endovascular treatment of infrarenal aortic aneurysm.

The aim of this study was to determine the correlation between the measurement of transverse diameter of the proximal neck on computed tomographic angiography (CTA) and graduated catheter aortography in patients who are candidates for endovascular graft placement in order to replace, if both measurements are equivalent, aortography for CTA alone. Preoperative dual-slice CTA and graduated catheter aortography were performed in 35 consecutive patients with infrarenal aortic aneurysm within 10 days. Transverse proximal neck diameters were measured on a true axial section on CTA reconstructions and on aortographic images, always 6 mm distal from the most inferior main renal artery.
