Paru Patrawalla, Mangala Narasimhan, Lewis Eisen, Ariel L Shiloh, Seth Koenig, Paul Mayo
OBJECTIVE: Training in critical care ultrasonography is an essential tool in critical care medicine and recommended for fellowship programs in pulmonary and critical care medicine. Major barriers to implementing competency-based training in individual fellowship programs include a lack of expert faculty, time, and funding. Our objective was to investigate whether regional collaboration to deliver an introductory critical care ultrasonography course for fellows might overcome these barriers while achieving international training standards...

A 44- and a 66-year-old woman underwent nasopancreatic drainage (NPD) to treat obstructive pancreatitis secondary to a pancreatic metastasis from lung cancer. Both patients were diagnosed with stage IV lung cancer and underwent chemotherapy for 17 and 15 months, respectively. Abdominal ultrasonography and computed tomography revealed a solid pancreatic tail tumor measuring 2.5 cm and 1.3 cm in diameter, respectively. Additionally, we observed dilatation of the upstream main pancreatic duct (MPD) and edematous parenchyma with peripancreatic inflammatory changes limited to the pancreatic tail...

Cryptococcal infection results from inhalation of fungal spores and usually is confined to the lungs, but may disseminate systemically. Radiologically, cryptococcal infection has multiple forms of presentation. The diagnosis is usually based on fungal isolation from cultured clinical specimens. Long term antifungal therapy is recommended, but surgical procedures may eventually be necessary when large thoracic symptomatic masses are present. We report a case of a 41-year-old male, immunocompetent, investigating a palpable mass in the left supraclavicular region associated with unintentional weight loss over the last three months...

AIMS: The current algorithm in transthoracic echocardiography (TTE) proposed in the 2016 ASE/EACVI recommendation for the estimation of left ventricular filling pressure (LVFP) is quite complex and time-consuming. B-lines, in lung ultrasonography (LUS), could constitute an interesting tool for LVFP evaluation in clinical practice, although data regarding their association with invasive haemodynamics are lacking. The purpose of this study was to explore the diagnostic accuracy of B-lines in identifying elevated left ventricular end-diastolic pressure (LVEDP)...

We report a 49-year-old woman who presented with a hypertensive crisis and acute heart failure and reduced left ventricular systolic function. An abdominal ultrasonography revealed a huge lobulated heterogeneous mass at the lower pole of the right kidney and a mass over the left suprarenal area, which were further delineated by magnetic resonance imaging. The patient underwent laparoscopic right radical nephrectomy and left adrenalectomy. Histopathological analysis confirmed the diagnoses of clear cell renal cell carcinoma of the right kidney with metastasis to the lung; and atypical pheochromocytoma of the left adrenal gland...

BACKGROUND: Pneumonia is one of the most frequent widespread and severe infectious diseases in pediatric patients worldwide. Pneumonia is characterized by high incidence and possibility of complications in the course of the disease in pediatric patients. For this reason, there is a need to have a rapid and safe diagnostic method to recognize it. Imaging diagnostic tools, such as x-ray examinations, necessitate caution while using these methods. To date, there have been lots of studies with the aim to determine the role of lung ultrasonography (LUS) in the diagnosis of inflammatory lesions in children...

BACKGROUND: Point-of-care ultrasonography (POCUS) is increasingly used for both diagnostic and guided procedures. Increasingly, POCUS has been used for identification of pneumonia and to assist in the differentiation of pleural effusions, as well as to guide thoracentesis. As such, there is a need for training with ideally high-fidelity lung ultrasound phantoms to ensure ultrasound proficiency and procedural competency. Unfortunately, most commercial ultrasound phantoms remain expensive and may have limited fidelity...

Among the different clinical presentations of bovine respiratory disease, active pneumonia, defined as an infection of the lower airway with signs of inflammation, is the most important to diagnose correctly so appropriate treatment can be initiated. Diagnostic tests that accurately identify cases of active pneumonia are lacking; however, thoracic ultrasonography (TUS) seems promising. The primary objective of this study was to estimate the accuracy of TUS compared to reference tests for the diagnosis of active pneumonia in pre-weaned calves, using a latent-class model method (LCM)...

The diaphragm is well known for its role as the principal muscle of respiration. However, according to previous studies, its role is multifactorial, from breathing through pain perception, regulation of emotional sphere, collaborating in gastroesophageal functions, facilitating the venous and lymphatic return, to an essential role in the maintenance of lumbar spine stability. The purpose of the study was to examine whether diaphragm function parameters (thickness and range of motion) are associated with static balance maintenance...

Ventilator-associated pneumonia (VAP) is the most frequent nosocomial infection in intensive care units (ICU) and is associated with increased mortality, use of antimicrobials, longer mechanical ventilation, and higher healthcare costs. Lung ultrasonography (LUS) can be used at the bedside and gained widespread acceptance in ICU. Although the visualization of a single LUS sign cannot be considered specific for a diagnosis, clinically-driven LUS examination in particular setting and clinical conditions allow ruling in or out quickly and accurately several causes of acute respiratory failure...

RATIONALE: Radiofrequency ablation (RFA) has become the reliable, effective, and less invasive treatment for small primary or metastatic hepatic tumors. Hepatic tumors that located immediately beneath the diaphragm are difficult to treat with percutaneous RFA due to poor visualization by percutaneous ultrasonography and the close location of the heart or lung. A transthoracic approach has been proposed to be an alternative for hepatic tumors located beneath the diaphragm that are difficult to access by conventional percutaneous or laparoscopic approaches...
