Chest ultrasound

Our study aimed to assess the benefit of intrapleural fibrinolysis before resorting to surgery to treat complicated parapneumonic effusion and empyema. We conducted a retrospective and descriptive study, including all patients hospitalized in the intensive care unit (ICU) of the Abderhaman Mami hospital, Tunisia for empyema treated with instillation of intrapleural fibrinolytic therapy between the 1st January 2000 and 31st December 2016. In all patients, empyema was diagnosed on clinical features, imaging findings (chest X-ray, thoracic echography and/or computed tomography (CT), and microbiological data...

Chronic interstitial lung diseases (ILDs) require frequent point-of-care monitoring. X-ray-based methods lack resolution and are ionizing. Chest computerized tomographic (CT) scans are expensive and provide more radiation. Conventional ultrasound can detect severe lung damage via vertical artifacts (B-lines). However, this information is not quantitative, and the appearance of B-lines is operator- and system-dependent. Here we demonstrate novel ultrasound-based biomarkers to assess severity of ILDs. Lung alveoli scatter ultrasound waves, leading to a complex acoustic signature, which is affected by changes in alveolar density due to ILDs...

INTRODUCTION: There are no defined criteria for deciding to remove a non-functioning indwelling pleural catheter (IPC) when lung re-expansion on chest X-ray is incomplete. Chest computed tomography (chest CT) is usually used. The objective of this work is to validate the usefulness of chest ultrasound performed by a pulmonologist and by a radiologist compared to chest CT. PATIENTS AND METHODS: Prospective, descriptive, multidisciplinary and multicenter study including patients with malignant pleural effusion and non-functioning IPC without lung reexpansion...

Maternal (F0 ) exposure to late-gestation heat stress reduces their daughter's (F1 ) mammary gland fat pad mass (FP), parenchyma (PAR) mass, and epithelial cell proliferation when evaluated at birth and weaning, and go on to produce less milk in their first lactation. Herein, we investigated the effect of maternal late-gestation heat stress on whole-body growth and mammary development of their granddaughters (F2 ). Multiparous F0 cows had access to heat abatement (n = 41, shade, and active cooling via fans and water soakers) or not (n = 41, shade only) for the last 56 d of gestation during a subtropical summer...

BACKGROUND: Surgical management for Paget's disease (PD) of the breast is controversial. This study aims to assess outcomes of PD patients based on procedure type and determine the reliability of imaging in estimating disease extent. METHODS: A retrospective review analyzed clinicopathologic data of PD patients between 2009 and 2022. Pre-operative imaging size (PIS) was compared to post-operative pathology size (PPS) looking at concordance. RESULTS: Thirty patients had PD, 21 underwent total mastectomy (TM) and 9 breast conserving surgery (BCS)...

PURPOSE: Immunotherapy is a leading approach for treating advanced non-small cell lung cancer (NSCLC) by targeting the PD-1/PD-L1 checkpoint signaling pathway, particularly in tumors expressing high levels of PD-L1 (Jug et al. in J Am Soc Cytopathol 9:485-493, 2020; Perrotta et al. in Chest 158: 1230-1239, 2020). Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive method to obtain tissue for molecular studies, including PD-L1 analysis, in unresectable tumors (Genova et al...

OBJECTIVE: To analyze treatment outcomes in children with traumatic injuries of the diaphragm. MATERIAL AND METHODS: We followed-up 14 children aged 3-18 years with traumatic injuries of the diaphragm. Diagnostic measures included anamnesis, physical examination, pleural and abdominal puncture, bladder catheterization, ultrasound and X-ray examination including CT. RESULTS: Traumatic brain injury and thoracoabdominal trauma prevailed in children with traumatic injuries of the diaphragm...

A 60-year-old female with a past medical history of hypertension presents to the ED with one day of throbbing left knee pain with associated numbness that worsened with ambulation. EKG shows lateral T-wave inversions with no prior for comparison. The patient had bloodwork drawn and a chest x-ray ordered. Her pain was improving with acetaminophen, and during further workup, she went into cardiac arrest. The advanced cardiac life support protocol was initiated, the patient was intubated, and point-of-care ultrasound revealed pericardial effusion...

OBJECTIVE: The Objective was to determine the diagnostic accuracy of thoracic ultrasound (TUS) for detecting (ILD) in rheumatoid arthritis (RA) with respiratory symptoms. METHODS: Individuals with RA visiting Rheumatological outpatient clinics in the Region of Southern Denmark were systematically screened for dyspnoea, cough, recurrent pneumonia, prior severe pneumonia or a chest X-ray indicating interstitial abnormalities. Eighty participants with a positive screening were consecutively included...

BACKGROUND: Small-bore chest drains are now the most common drains for treating pleural effusion (PE), but knowledge on complications is limited especially in malignant PE and empyema. We aimed to evaluate rate of complications of ultrasound guided small bore chest drains [6-10 French (F)] by PE etiology. METHODS: Retrospective cohort study of 484 chest drains inserted in 330 adults in a Swedish department 2018-2020. Rate of complications (blockage, dislocation, infection, or misplacement) and repeat intervention (new drain within 2 weeks or surgery) was analyzed by effusion type (organ failure, parapneumonic, malignant, empyema, other, unknown), age, sex, seniority of radiologist, and bore size using multivariable logistic regression...

BACKGROUND: The immune-related adverse effects after immune checkpoint inhibitors (ICIs) treatment have always been a hot topic. Although the incidence of myocarditis is not high among the related adverse effects, the mortality rate is extremely high once it occurs. In the past, the risk of cancer therapy-related cardiac dysfunction (CTRCD) after drug treatment was evaluated based on imaging examinations, but this evaluation still had certain limitations. Currently, the extracellular volume (ECV) score measurement calculated using cardiac magnetic resonance T1 mapping has become a reliable method for evaluating myocardial toxicity and computed tomography (CT) examination may become an alternative...

Sarcoidosis is a multisystemic granulomatous disease that is frequently localized in the lungs and lymph nodes. We herein report a case of pulmonary sarcoidosis secondary to shin'iseihaito administration. During remission with 5 mg prednisolone/day of maintenance treatment, chest computed tomography revealed a mass in the left lower lobe with re-enlarged bilateral hilar/mediastinal lymph nodes. Transbronchial lung biopsy of the mass and endobronchial ultrasound-guided transbronchial needle aspiration of mediastinal lymph nodes revealed adenocarcinoma and noncaseating granulomas, respectively...

Introduction Computed tomography (CT) has a high sensitivity for diagnosing COVID-19 pneumonia in critically ill patients, but it has significant limitations. Lung ultrasonography (LUS) is an imaging method increasingly used in intensive care units. Our primary aim is to evaluate the relationship between LUS and CT images by scoring a critically ill patient who was previously diagnosed with COVID-19 pneumonia and underwent CT, as well as to determine their relationship with the patient's oxygenation. Methods This was a single-center, prospective observational study...

Situs inversus totalis (SIT) is a rare medical condition characterized by a complete mirror-image reversal of the normal positioning of the internal organs. Aristotle initially described situs inversus in animals, while Fabricius first characterized it in humans. Although the specific cause is uncertain, there is evidence of autosomal recessive and X-linked inheritance. Before seeking treatment for an unrelated ailment, many people with SIT are unaware of their distinct anatomy, as in our case. The presented case is a 30-year-old female patient from Central Ethiopia, presented to Hakim Gizaw Teaching Hospital outpatient department of medicine with the complaint of right-sided anterior chest pain for five days...

Coronary embolism (CE) is a rare cause of non-atherosclerotic acute coronary syndrome (ACS). The clinical presentation is similar to ACS, and the diagnosis is supported by Shibata criteria. Atrial fibrillation is the main reported etiology in CE cases. Management includes percutaneous intervention with thromboaspiration and anticoagulation. The following case is a description of a patient with acute chest pain and recently diagnosed atrial fibrillation (AF) with a rapid ventricular response, is described. A thrombotic lesion in the distal right coronary artery (RCA) of embolic origin, was documented...

Pneumonia is a clinical syndrome characterised by fever, cough and alveolar infiltration of purulent fluid, caused by infection with a microbial pathogen. It can be caused by infections with bacteria, viruses or fungi, but a causative organism is identified in less than half of cases. The most common type of pneumonia is community-acquired pneumonia, which is caused by infections acquired outside the hospital. Current guidelines for pneumonia diagnosis require imaging to confirm the clinical suspicion of pneumonia...

Radiological and nuclear medicine methods play a fundamental role in the diagnosis and staging of patients with lung cancer. Imaging is essential in the detection, characterisation, staging and follow-up of lung cancer. Due to the increasing evidence, low-dose chest computed tomography (CT) screening for the early detection of lung cancer is being introduced to the clinical routine in several countries. Radiomics and radiogenomics are emerging fields reliant on artificial intelligence to improve diagnosis and personalised risk stratification...

Pulmonary mucormycosis is a rare but highly lethal fungal infection, usually affecting immunocompromised patients. Pulmonary mucormycosis was also a critical problem that complicated the later part of the clinical course of COVID-19 in India. Early diagnosis of the disease, combined with aggressive treatment, is crucial for patient survival. Fibreoptic bronchoscopy is a useful procedure for diagnosis of pulmonary mucormycosis, but image-guided percutaneous biopsy efficiently samples lesions abutting the chest wall...

Acute myocardial infarction (AMI) is a prevalent and high-mortality cardiovascular condition. Despite advancements in revascularization strategies for AMI, it frequently leads to myocardial ischemia-reperfusion injury (IRI), amplifying cardiac damage. Murine models serve as vital tools for investigating both acute injury and chronic myocardial remodeling in vivo. This study presents a unique closed-chest technique for remotely inducing myocardial IRI in mice, enabling the investigation of the very early phase of occlusion and reperfusion using in-vivo imaging such as MRI or PET...

Breast cancer affects around 13% of women. Breast cancer gene 1 ( BRCA1 ) carriers are prone to lung and lymph node metastasis, while breast cancer gene 2 ( BRCA2 ) carriers tend to have bone metastasis. Findings of pulmonary nodules, mediastinal lymphadenopathy, and elevated markers such as cancer antigen (CA) 15-3 and CA 27-29 suggest metastatic disease. Here, we present the case of a patient with BRCA1 -positive breast cancer in remission and a history of ovarian cancer with mediastinal lymphadenopathy and pulmonary nodules, with avid fluorodeoxyglucose uptake on positron emission tomography (PET) scan and elevated CA 15-3 and CA 27-29...
