The present study describes the case of a 48-year-old man who was diagnosed with lung adenocarcinoma with an epidermal growth factor receptor (EGFR) 21 L858R mutation. The patient received surgery and adjuvant chemotherapy. When multiple lung metastases appeared, icotinib was administered. Following resistance to icotinib, biopsy by endobroncheal ultrasonography for a right lung hilar lymph node revealed transformation to a neuroendocrine morphology. Neuron-specific enolase (NSE) levels were elevated, accompanied with disease progression following transformation to the neuroendocrine morphology...

Bilateral pulmonary sequestration (PS) is a very rare congenital malformation. We describe a case of bilateral intralobar pulmonary sequestration (ILS) in a newborn. Both sequestrations received arterial supply from separate branches of the descending aorta and venous drainage was into ipsilateral inferior pulmonary veins. Prenatal ultrasonography showed cystic changes in the lungs. Computed tomography angiography (CTA) with supplemental two-dimensional (2D) and three-dimensional (3D) images was performed to clearly define the pathology and revealed bilateral intralobar pulmonary sequestration with aberrant blood supply...

Bovine respiratory disease (BRD) is a complex disease process and many reports emphasize the negative implications of clinical BRD in dairy calves. Early diagnosis can be difficult because of inconsistent or absent clinical signs; however, the use thoracic ultrasonography has the potential to improve detection of respiratory disease. Earlier detection of BRD may result in actions to improve calf welfare and production. The objective of this prospective cohort study was to determine if lung consolidation (LC) in young dairy calves influenced age at first calving (AFC), first-lactation milk production, and survival to the end of first lactation...

BACKGROUND: Acute dyspnea is one of the main reasons for admission to Emergency Department (ED). Availability of ultraminiaturized pocket ultrasound devices (PUD) adds diagnostic power to the clinical examination. The aim of this study was to identify an integrated ultrasound approach for diagnosis of acute heart failure (acute HF), using PUD and combining evaluation from lung, heart and inferior vena cava (IVC). METHODS: We included 102 patients presenting to the ED of "Antonio Cardarelli" Hospital in Naples (Italy) for acute dyspnea (AD)...

BACKGROUND: Although pulmonary congestion can be quantified by lung ultrasonography (LUS) in heart failure (HF), little is known about LUS findings (B-lines) in different HF phenotypes. This prospective cohort study investigated the prevalence, clinical and echocardiographic correlates of B-lines in ambulatory HF patients with preserved (HFpEF) or reduced ejection fraction (HFrEF) compared with hypertensive patients. We related LUS findings to 12-month HF hospitalizations and all-cause mortality...

BACKGROUND AND AIMS: Alpha-1 antitrypsin (A1AT) is the most abundant serine protease inhibitor in human blood and exerts important anti-inflammatory and immune-modulatory effects. In combination with smoking or other long-term noxious exposures such as occupational dust and fumes, genetic A1AT deficiency can cause chronic obstructive pulmonary disease, a condition with elevated cardiovascular risk. The effects of A1AT deficiency on cardiovascular risk have hardly been studied today. METHODS: Using data from 2614 adults from the population-based SAPALDIA cohort, we tested associations of serum A1AT and SERPINA1 mutations with carotid intima-media thickness (CIMT, measured by B-mode ultrasonography) or self-reported arterial hypertension or cardiovascular disease in multiple regression models using a Mendelian Randomization like analysis design...

INTRODUCTION AND OBJECTIVES: Different echographic and fetal magnetic resonance (MRI) measurements have been described in the diagnosis of associated malformations and the prognosis of congenital diaphragmatic hernia (CDH). We have reviewed our experience searching for useful isolated or combined parameters and how MRI can complement ultrasound. MATERIAL AND METHODS: We evaluated 29 fetuses with CDH. We examined ultrasonography: Lung to Head (LHR o/e) and in MRI: ipsilateral lung volume (IPV) and total expressed as percentage of observed / expected lung volume (VPT o/e) and percentage of herniated liver (PHH)...

RATIONALE: Menkes disease (MD), also known as Menkes kinky hair disease, is a fatal neurodegenerative disease caused by a defect in copper metabolism. The symptoms involve multiple organ systems, such as the brain, lung, gastrointestinal tract, urinary tract, connective tissue, and skin. There is currently no cure for this disease entity, and patients with the classic form of MD usually die from complications between 6 months and 3 years of age. Intracranial hemorrhage secondary to tortuous intracranial arteries is a well-known complication of MD, but spontaneous retroperitoneal hemorrhage, to the best of our knowledge, has never been reported in a patient with MD...

The use of Point-of-care ultrasonography (POC Ultrasonography) is getting more and more important in the bedside care of patients, especially in emergency- and intensive care units. In addition to the focused sonography of the heart, lungs and abdomen, the POC Ultrasonography recently includes also cases in prehospital care. Increasingly special applications in intensive care, e.g. the assessment of weaning from mechanical ventilation or evaluation of the hemodynamics of a patient by means of sonographic control, gain meaning...

As far as we are aware, there are no previous reports on the pathologic conditions of buoyancy disorders in Ambystoma mexicanum. Herein, we describe various clinical test results, clinical outcomes, and the pathological findings of an experimental pneumonectomy procedure in 3 A. mexicanum exhibiting abnormal buoyancy. The 3 pet A. mexicanum were adults, and their respective ages and body weights were 1, 5, and 6 yr and 48, 55, and 56 g. Two of these cases were confirmed via radiographic examination to have free air within the body cavity, and all 3 cases were found via ultrasonography to have an acoustic shadow within the body cavity and were diagnosed with pneumocoelom...

Chest wall neoplasms mainly include malignancies, metastatic in particular. Differential diagnosis should include clinical data; tumor location, extent, delineation; the degree of homogeneity; the presence of calcifications; the nature of bone destruction and the degree of vascularization. The aim of the paper is to present both the benefits and limitations of ultrasound for the diagnosis of chest wall neoplasms. The neoplastic process may be limited to the chest wall; it may spread from the chest wall into the intrathoracic structures or spread from the inside of the chest towards the chest wall...

Pulmonary embolism (PE) is a clinical emergency that will increase the mortality if complicated with unstable hemodynamics. Because of its nonspecific clinical symptoms, it's a great challenge to make a PE diagnosis. The golden standard to diagnose PE is computed tomography of pulmonary artery (CTPA), but a diagnosis of PE also composed of evaluation of PE risk factors, possibilities, and risk stratification. Ultrasonography may detect right ventricle strain related to hemodynamic change, intravascular thrombosis, thrombosis in right heart or pulmonary arteries, pulmonary infarction, and local pleural effusion...
