Recently small peripheral lesions have been discovered due to development of computed tomography (CT) instruments and dissemination of CT examination etc. Histological or cytological diagnosis for peripheral lesions is recommended to be performed. The diagnostic yield for peripheral pulmonary lesion depends on the size. Transbronchial lung biopsy (TBLB) was developed using techniques such as navigation system( vitual bronchoscopic navigation:VBN), endobronchial ultrasonography(EBUS) using guide sheath(GS), extremely small bronchoscope and the like for lesions of 2...

Immunotherapy with immune checkpoint inhibitors (ICIs) for cancer has become increasingly prescribed in recent years. Indeed, it is used to treat both solid and hematological malignancies due to their considerable potential in treating melanoma, non-small cell lung and other cancers. Immune-mediated related adverse endocrine toxicity, and especially thyroiditis, are seen as a growing problem needing specific screening and management. This study aims at describing thyroid dysfunctions induced by the ICIs marketed in France, which are registered in the French Pharmacovigilance database...

Two types of congenital bronchial atresia (proximal and peripheral) have been classified. We report two cases of peripheral bronchial atresia diagnosed by prenatal ultrasonography (US) and magnetic resonance imaging (MRI). Evaluating an enlarged lung mass that is homogeneously hyperechoic on US and hyperintense on T2-weighted MRI can help in determining whether bronchial atresia is present. Proximal type is suggested when a dilated main bronchus is observed as a tubule structure of an involved lung hilum. In our cases, T2-weighted MRI revealed homogeneously hyperintense lung lesion with decreased signal intensity of adjacent lobe, flattening diaphragm, and mediastinal shift...

OBJECTIVES: Venous thromboembolism (VTE) is a common postoperative complication. Previous studies have shown that the incidence of VTE after major thoracic surgery ranges from 2.3% to 15%. However, there have been no such data from China so far. To evaluate the incidence of postoperative VTE, we conducted a single-centre, prospective cohort study. METHODS: Patients who underwent lung resections between July 2016 and March 2017 were enrolled in this study. None of the patients received any prophylaxis perioperatively...

OBJECTIVE: A new technique of transthoracic lung ultrasonography (TLS) has emerged and demonstrated promising results in acute heart failure diagnosis at an early stage. However, the diagnostic value of ultrasound lung comets (ULCs) for acute heart failure (AHF) performed in busy emergency department (ED) is uncertain. The present meta-analysis aimed to assess the diagnostic efficiency of ULCs in AHF. METHODS: We conducted a search on online journal databases to collect the data on TLS performed for diagnosing AHF published up to the end of July 2017...

When intracranial hypertension and severe lung damage coexist in the same clinical scenario, their management poses a difficult challenge, especially as concerns mechanical ventilation management. The needs of combined lung and brain protection from secondary damage may conflict, as ventilation strategies commonly used in patients with ARDS are potentially associated with an increased risk of intracranial hypertension. In particular, the use of positive end-expiratory pressure, recruitment maneuvers, prone positioning, and protective lung ventilation can have undesirable effects on cerebral physiology: they may positively or negatively affect intracranial pressure, based on the final repercussions on PaO2 and cerebral perfusion pressure (through changes in cardiac output, mean arterial pressure, venous return, PaO2 and PaCO2 ), also according to the baseline conditions of cerebral autoregulation...

PURPOSE: Modern lung ultrasound (US) is mainly applied not only in critical care, emergency medicine, and trauma surgery, but also in pulmonary and internal medicine. In some cases, pneumothorax (PTX) distinguishes with bullous diseases. In this study, we aimed to discuss the success of US on detecting PTX versus bullae. METHODS: We performed a prospective blinded study. Patients underwent thorax computed tomography (CT) if bullae or pneumothorax could not be differentiated from the chest radiography...

BACKGROUND: Convenient approaches for accurate biopsy are extremely important to the diagnosis of lung cancer. We aimed to systematically review the clinical updates and development trends of approaches for biopsy, i.e., CT-guided PTNB (Percutaneous Transthoracic Needle Biopsy), ENB (Electromagnetic Navigation Bronchoscopy), EBUS-TBNA (Endobroncheal Ultrasonography-Transbronchial Needle Aspiration), mediastinoscopy and CTC (Circulating Tumor Cell). METHODS: Medline and manual searches were performed...

Objective was to evaluate the echotexture and characteristics during terminal development of canine foetal respiratory and hepatic systems through elastographic examinations. Fifteen pregnant bitches were evaluated by ultrasonography twice daily, from the 53rd gestational day until whelping, and images obtained from 120 to 0 h before parturition were analysed. Images of foetal lungs and liver were recorded and then used for computer-assisted analyses to determine quantitative attributes. Acoustic Radiation Force Impulse (ARFI) elastographic of internal organs were classified as 'soft' (white areas) or 'hard' (dark areas) and quantitative analyses determined the mean shear wave velocities (SWV) of foetal lungs and liver...

Major aortopulmonary collateral arteries (MAPCAs) are unique vessels associated with hypoxia induced by congenital heart disease (CHD). Although MAPCAs are essential to supply blood to the lungs, their development and proliferation can induce life-threatening complications, such as rupture into the lung. Here, we describe a rare case of esophageal bleeding from MAPCAs in a CHD patient, which was successfully treated by transcatheter arterial embolization (TAE). A 16-year-old male with CHD experienced a hematemesis and melena after the Bentall procedure to treat valvular heart disease...

BACKGROUND: Widespread implementation of transbronchial lung cryobiopsy (TBLCB) in the diagnostic approach to diffuse parenchymal lung disease has prompted a call for standardization of technique to optimize safety and diagnostic yield. Thoracic ultrasound (TUS) is proving effective in detecting postconventional transbronchial biopsy pneumothorax (PTX). However, TUS does not obviate the need for chest radiography (CXR) which quantifies and guides treatment of PTX. To our knowledge, this is the first experience evaluating TUS's reliability to rule-out PTX post-TBLCB in diffuse parenchymal lung disease...

The authors report their findings regarding lung ultrasound profiles in a population of transplant recipients. Twenty-two patients were studied once each in multiple different ultrasound windows focusing on pleural, lung, and diaphragmatic signatures. All studies were performed in presumably otherwise healthy recipients at an outpatient follow-up visit at least 3 months after transplantation. Those with recent pulmonary infections or decline in lung function were excluded from enrollment. The majority of scans revealed otherwise normal lungs with lung sliding, but there were more abnormalities than one would expect in a healthy control group...

BACKGROUND: The diagnostic algorithm for venous thromboembolism (VTE) currently involves a composite of pre-test probability, D-dimer and imaging. Other laboratory tests, however, may assist in the identification of patients with VTE. AIM: To assess the accuracy of different coagulation tests (D-dimer, thrombin generation, phospholipid-dependent (PPL) clotting time, soluble P-selectin (sP-selectin)) as biomarkers of acute VTE. METHODS: Random samples arriving at the Coagulation Laboratory at Mater Dei Hospital (Msida, Malta) from the Accident and Emergency Department with a request for D-dimer measurement were collected between August 2015 and February 2016...

BACKGROUND: The risk factors for rapid growth and early metastasis of papillary thyroid carcinoma (PTC) and the role of coexisting Graves' disease in the clinical course of PTC remain uncertain in children. CASE DESCRIPTION: We report on a Japanese girl, whose PTC rapidly grew and metastasized within 4 years. Graves' disease was diagnosed by the presence of serum TSH receptor antibodies at 8 years of age when thyroid ultrasonography detected no nodules. After 4 years of effective treatment with thiamazole, multifocal nodules - up to 47 mm in diameter - were detected on thyroid ultrasonography...

Proficiency in echocardiography and lung ultrasound has become essential for anesthesiologists and critical care physicians. Nonetheless, comprehensive echocardiography measurements often are time-consuming and technically challenging, and conventional 2-dimensional images do not permit evaluation of specific conditions (eg, systolic anterior motion of the mitral valve, pneumothorax), which have important clinical implications in the perioperative setting. M-mode (motion-based) ultrasonographic imaging, however, provides the most reliable temporal resolution in ultrasonography...

BACKGROUND: The diaphragm changes in COPD lead to functional inefficiency correlated to lung function loss. Muscle-fiber shortening follows lung hyperinflation, which results in a chronic mechanical disadvantage that impairs diaphragmatic mobility that worsens in COPD exacerbations. OBJECTIVES: To correlate the diaphragmatic mobility loss to COPD severity by using M-mode ultrasonography and to verify if the diaphragmatic mobility can improve after in-patient pulmonary rehabilitation...
