BACKGROUND: There is a growing body of evidence to support the utility of lung point-of-care ultrasound (POCUS) in pediatric patients with multiple pulmonary pathologies, particularly pneumonia. As we increase our use of lung POCUS for pediatric patients with respiratory complaints, we must be mindful of the normal anatomy and sonographic findings within the pediatric chest and aware of how to distinguish normal findings (e.g., thymus) from pathologic findings (e.g., consolidation). CASE REPORTS: We report four cases of pediatric patients who presented to the Emergency Department with respiratory complaints for which POCUS was able to distinguish lung consolidation and normal thymus in the anterior chest...

Pulmonary capillary hemorrhage (PCH) can be induced by diagnostic ultrasound-a potential safety issue. Anesthetized rats were intubated for intermittent positive-pressure ventilation (IPPV) with 0 end-expiratory pressure, +4 cm H2 O end-expiratory pressure (PEEP) and -4 cm H2 O end-expiratory pressure (NEEP). Rats were imaged at 7.6 MHz with a Philips HDI 5000 ultrasound machine. The output was low (mechanical index [MI] = 0.22) for aiming and then was raised for 5 min in 20 different exposure groups with n = 8...

BACKGROUND: Septic pulmonary embolism (SPE) is a rare disorder caused by metastasis of infectious thrombi to the lungs. Most commonly, this occurs as a result of infectious endocarditis. This clinical entity may easily be confused for more common and less mortal diagnoses such as pneumonia, bronchitis, or pulmonary embolism. CASE REPORT: A 47-year-old woman presented in respiratory distress with a complaint of cough productive of rusty sputum, shortness of breath, and pleuritic chest pain...

BACKGROUND: The 2016 CHEST consensus guidelines recommend use of either 21- or 22-G needles for endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). We decided to prospectively compare sample adequacy and diagnostic yield of the 19-G with the 22-G EBUS needle, hypothesizing that a larger gauge difference might magnify the differences between 2 needle sizes. METHODS: Twenty-seven patients undergoing EBUS-TBNA at our institution were evaluated...

Ultrasound contrast-enhanced stress echocardiography improves endocardial visualization, but diagnostic test rates versus stress myocardial perfusion imaging (MPI) have not been studied. A prospective randomized trial was performed between April 2012 and October 2014 at a single-center, safety net hospital. Hospitalized patients referred for noninvasive stress imaging were randomized 1:1 to stress echocardiography or stress MPI. The primary outcome was diagnostic test rate defined as interpretable images and achievement of >85% of age-predicted maximal heart rate (for dobutamine and exercise)...

To validate a new modified method for measuring the anthropometric Haller index (HI), obtained without radiological exposure. This new method was based on the use of a rigid ruler and of a 2.5 MHz ultrasound transducer for the assessment of latero-lateral and antero-posterior chest diameters, respectively. We enrolled 100 consecutive patients (mean age 67.9 ± 14.5 years, 55% males), who underwent a two-plane CXR, for any clinical indication, over a four-month period. In all patients, the same radiologist calculated the conventional radiological HI (mean value 1...

BACKGROUND: When a patient arrives at the emergency department (ED) presenting with symptoms of acute decompensated heart failure (ADHF), it is possible to reach a definitive diagnosis through many different venues, including medical history, physical examination, echocardiography, chest X-ray, and B-type natriuretic peptide (BNP) levels. Point-of-care ultrasound (POCUS) has become a mainstream tool for diagnosis and treatment in the field of emergency medicine, as well as in various other departments in the hospital setting...

Chest ultrasonography (CU) is a noninvasive imaging technique able to provide an immediate diagnosis of the underlying aetiology of acute respiratory failure and traumatic chest injuries. Given the great technologies, it is now possible to perform accurate CU in remote and adverse environments including the combat field, extreme sport settings, and environmental disasters, as well as during space missions. Today, the usage of CU in the extreme emergency setting is more likely to occur, as this technique proved to be a fast diagnostic tool to assist resuscitation manoeuvres and interventional procedures in many cases...

Muscle-invasive bladder cancer (MIBC) has a tendency toward urothelial multifocality and is at risk for local and distant spread, most commonly to the lymph nodes, bone, lung, liver, and peritoneum. Pretreatment staging of MIBC should include imaging of the urothelial upper tract for synchronous lesions; imaging of the chest, abdomen, and pelvis for metastases; and MRI pelvis for local staging. CT abdomen and pelvis without and with contrast (CT urogram) is recommended to assess the urothelium and abdominopelvic organs...

BACKGROUND: Chest ultrasound (CUS) is the gold standard to detect pleural adhesions before pleural maneuvers. However, the CUS technique is not available in all countries where the assessment is only based on clinical examination and chest radiography. OBJECTIVE: To assess the value of lateral decubitus chest radiography (LDCR) to detect pleural adhesions. METHODS: Consecutive patients with pleural effusions undergoing LCDR followed by medical thoracoscopy the day after were identified from an institutional database...

BACKGROUND AND OBJECTIVE:  Congenital pulmonary airway malformation (CPAM) is a group of rare congenital malformations of the lung and airways. Lung ultrasound (LU) is increasingly used to diagnose neonatal respiratory diseases since it is quick, easy to learn, and radiation-free, but no formal data exist for congenital lung malformations. We aimed to describe LU findings in CPAM neonates needing neonatal intensive care unit (NICU) admission and to compare them with a control population...

BACKGROUND: Thoracic paravertebral block is a technique for perioperative analgesia in patients undergoing thoracic, chest wall, or breast surgery, or for pain management with rib fractures, which can be performed with or without ultrasound guidance. The ultrasound guidance technique can be used to identify the thoracic paravertebral space, guide needle placement, monitor the spread of local anesthetic (LA) solution, and reduce complications such as pleural puncture and pneumothorax. The possibility of assessing anesthetic spread in real time using ultrasound guidance during paravertebral block offers numerous advantages, including the immediate and accurate identification of the extent of nervous block, with a consequent reduction of LA dose...

Transthoracic ultrasound has lately emerged as a useful diagnostic tool for respiratory physicians in the diagnosis of diverse pulmonary diseases, usually including pleural effusion and pneumothorax. However, the use of chest ultrasound may be also critical in the evaluation of chest wall diseases. Therefore, we present an interesting case of a patient with metastases of lung cancer to the rib, detected during the chest wall ultrasound examination. By representing a non-invasive, surface-imaging technique with several advantages, chest ultrasound may evolve to a valid, bed-side diagnostic tool for the diagnosis and follow up of lung cancer with metastases in the chest wall...

Cuff positions of endotracheal tubes should be confirmed to ensure safe anesthesia. However, determining the cuff positions relative to the cricoid by using chest radiography or fiberoptic bronchoscopy is difficult. We identified the cephalad edges of saline-inflated pediatric endotracheal tube cuffs relative to the cricoid on longitudinal ultrasound images over the larynx and trachea in 2 children. Thereafter, we adjusted the endotracheal tube depths and confirmed the cuff positions relative to the cricoid...

Convex probe endobronchial ultrasound (CP-EBUS) and stereotactic body radiotherapy (SBRT) are valuable tools in the diagnosis, staging, and treatment of thoracic malignancies. With widespread clinical adoption, novel uses of CP-EBUS beyond mediastinal diagnosis and staging continue to be discovered. SBRT is an attractive treatment strategy in early-stage lung cancer and oligo-metastatic disease of the chest when a surgical approach is either not feasible or desirable. Accurate application of SBRT is aided by the placement of radio-opaque fiducial markers (FM) to compensate for respiratory cycle movements...
