The use of transthoracic ultrasound has acquired a wide consensus among respiratory physicians during the last few years. The developing of portable and easily available devices favorites patient's bedside evaluation. Transthoracic ultrasound provides rapid, real-time and low-cost diagnostic information, allowing image-guided chest interventions and reducing procedural risks. The different acoustic impedance between aerated and not aerated organs produces artifacts known as A lines, B lines, sliding sign, lung point, etc...

Despite recent advances in screening methods, lung cancer remains the leading cause of cancer-related deaths worldwide. By the time lung cancer becomes symptomatic and patients seek treatment, it is often too advanced for curative measures. Low-dose computed tomography (CT) screening has been shown to reduce mortality in patients at high risk of lung cancer. We present a 66-year-old man with a 50-pack-year smoking history who had a right upper lobe (RUL) pulmonary nodule and left lower lobe (LLL) consolidation on a screening CT...

OBJECTIVE: There is limited knowledge about the potential relationship between asthma and heart function. Aim of our present study was to examine if asthma may be associated with manifest or subclinical heart dysfunction. METHODS: 72 allergic mild-to-moderate and severe asthma patients and 20 matched controls were enrolled in the study. Depending on the anti-asthmatic therapy, four subgroups of asthma patients were created: patients under long-acting beta2-agonists (LABA) and inhaled cortisone without oral cortisone treatment with (1a) versus without (1b) additional omalizumab therapy; patients with LABA, inhaled cortisone and omalizumab treatment with (2a) versus without (2b) oral cortisone...

BACKGROUND: Thoracic ultrasound is helpful to evaluate lung pathology in patients with acute dyspnea. Several studies have demonstrated the efficacy of point-of-care ultrasound in patients with extrapulmonary TB and HIV co-infection. This retrospective, open-label case-control study explores the role of lung ultrasound in the diagnosis of Pneumocystis jirovecii pneumonia (PJP) in HIV-positive patients. In particular, it highlights the potential role of specific sonographic features that may be unique to this population...

Lung cancer is one of the most frequent neoplastic diseases. To date, most lung cancer is diagnosed at an advanced stage, making it difficult to choose the diagnostic and therapeutic strategy. Surgical resection represents the best therapeutic solution. However, the best results are obtained only in the early stages of the disease. Lymph node involvement conditions the treatment (surgical or non-surgical approach). Mediastinoscopy is an effective and widely used method for mediastinal staging but does not allow us to reach many mediastinal lymph nodes...

BACKGROUND: Lung ultrasound is increasingly becoming a diagnostic tool in the critical care setting. B-pattern on a lung ultrasound is an artifact composed of multiple B-lines and correlates with interstitial edema. A randomized controlled trial concluded that bedside thoracic ultrasound could predict postextubation distress through changes in lung aeration during a weaning procedure; however, it could not screen patients before performance of a spontaneous breathing trial (SBT). METHODS: We conducted a 2-year, prospective, multicenter, observational study in 2 adult medical-surgical ICUs in southern Brazil...

A preterm neonate born at 27 weeks, with a birth weight of 555 g, was on continuous positive airway pressure (CPAP) for apnoea of prematurity and initially received total parenteral nutrition (TPN) through the umbilical venous catheter. Peripherally inserted central catheter (PICC) was inserted in the left basilica vein on day 8 to continue TPN. The baby developed respiratory distress with persistent hypoxia after TPN was initiated through the PICC line. The baby required mechanical ventilation due to worsening of respiratory distress, and chest X-ray, as well as ultrasound conducted 12 hours, postinfusion of TPN revealed right-sided pleural effusion...

METHODS: Twenty healthy subjects (10 males, age 28±5 years [mean ± SD]) lay supine, awake, with the head in a neutral position. Ventilation was monitored with inductance bands. Real-time B-mode ultrasound movies were analysed. We measured genioglossus motion (i) during spontaneous breathing, voluntary targeted breathing (normal tidal volume Vt), and voluntary hyperpnoea (at 1.5Vt and 2 Vt); (ii) during inspiratory flow resistive loading; (iii) with changes in end-expiratory lung volume (EELV)...

BACKGROUND: Transbronchial needle aspiration (TBNA), often used to sample lymph nodes for lung cancer staging, is subject to sampling error even when performed with endobronchial ultrasound. Optical coherence tomography (OCT) is a high-resolution imaging modality that rapidly generates helical cross-sectional images. We aim to determine if needle-based OCT can provide microstructural information in lymph nodes that may be used to guide TBNA, and improve sampling error. METHODS: We performed ex vivo needle-based OCT on thoracic lymph nodes from patients with and without known lung cancer...

OBJECTIVE: Whether systemic sclerosis (SSc) confers increased risk of venous thromboembolism (VTE) is uncertain. We evaluated the prevalence, risk factors, and effect of VTE on SSc survival. METHODS: A cohort study was conducted of subjects with SSc who fulfilled the American College of Rheumatology/European League Against Rheumatism classification criteria between 1970 and 2017. Deep vein thrombosis was defined as thrombus on extremity ultrasound. Pulmonary embolism was defined as thrombus on thorax computed tomography angiogram...

OBJECTIVES: Although lung ultrasound (US) has been shown to have high diagnostic accuracy in patients presenting with acute dyspnea, its precision in critically ill patients is unknown. We investigated common areas of agreement and disagreement by studying 6 experts as they interpreted lung US studies in a cohort of intensive care unit (ICU) patients. METHODS: A previous study by our group asked experts to rate the quality of 150 lung US studies performed by 10 novices in a population of mechanically ventilated patients...

Pulmonary artery anastomosis stenosis is a rare cause of right ventricular failure after orthotopic heart transplantation. In this case report, direct ultrasound of the pulmonary artery helped diagnose stenosis at a location not visible on transesophageal echocardiography or even with standard epicardial ultrasound views. It is important to evaluate all vascular anastomoses after heart or lung transplantation because surgical revision of these lesions is facile, but if left undiagnosed, significant morbidity or mortality is likely...

INTRODUCTION: The present study was aimed at comparing the diagnosis concordance of five echo probes of lung ultrasound (LUS) with CT scans in intensive care and emergency patients with acute respiratory failure. MATERIALS: This prospective, observational, pilot study involved 10 acute patients in whom a thoracic CT scan was performed. An expert performed an LUS reference exam using five different probes: three probes with a high-quality conventional echo machine (cardiac phased-array probe, abdominal convex probe, linear probe) and two probes (cardiac and linear) with a pocket ultrasound device (PUD)...

BACKGROUND AND OBJECTIVE: It can be challenging to delineate the target object in anatomical imaging when the object boundaries are difficult to discern due to the low contrast or overlapping intensity distributions from adjacent tissues. METHODS: We propose a topo-graph model to address this issue. The first step is to extract a topographic representation that reflects multiple levels of topographic information in an input image. We then define two types of node connections - nesting branches (NBs) and geodesic edges (GEs)...

Introduction: Liquid-based cytology (LBC), initially developed for screening gynecologic specimens, is now being used in nongynecologic aspiration and exfoliative specimens. In this study, the diagnostic yield and utility of thin-prep (TP) was compared with conventional preparations to ascertain its utility in improving the diagnosis of respiratory lesions. Materials and Methods: Bronchial washings (BW) and transbronchial needle aspirates (TBNA) (bronchoscopy/endobronchial ultrasound-guided) from 70 consecutive patients of mediastinal masses and endo/peribronchial growths were included...

Radial endobronchial ultrasound (R-EBUS) is one important diagnostic approach in non-small cell lung cancers (NSCLC). However, the small samples obtained from R-EBUS-guided transbronchial biopsies are sometimes insufficient for pathological and molecular diagnosis. Herein, we investigated the suitability of R-EBUS-guided bronchial brushing specimens for NSCLC diagnosis and EGFR genotyping. We enrolled 941 consecutive patients with peripheral pulmonary lesions who underwent R-EBUS. Cytology-positive brushing specimens from non-squamous NSCLC patients were tested for EGFR mutations...

Stress Echocardiography (SE) is an established diagnostic technique. For 40 years, the cornerstone of the technique has been the detection of regional wall motion abnormalities (RWMA), due to the underlying physiologically-relevant epicardial coronary artery stenosis. In the last decade, three new parameters (more objective than RWMA) have shown the potential to integrate and comple- ment RWMA: 1- B-lines, also known as ultrasound lung comets, as a marker of extra-vascular lung water, measured using lung ultrasound with the 4-site simplified scan symmetrically of the antero- lateral thorax on the third intercostal space, from mid-axillary to anterior axillary and mid- clavicular line; 2-left ventricular contractile reserve (LVCR), assessed as the peak stress/rest ratio of left ventricular force, also known as elastance (systolic arterial pressure by cuff sphygmomanome- ter/end-systolic volume from 2D echocardiography); 3- coronary flow velocity reserve (CFVR) on left anterior descending coronary artery, calculated as peak stress/rest ratio of diastolic peak flow velocity assessed using pulsed-wave Doppler...

BACKGROUND: Screening tests are typically evaluated for a single disease, but multiple tests for multiple diseases are performed in practice. The Prostate, Lung, Colorectal and Ovarian (PLCO) cancer screening trial assessed testing for four cancers simultaneously and can be viewed as a multiphasic cancer intervention. This paper presents overall and multiphasic findings of this trial. METHODS: The PLCO trial was a randomized multi-center trial conducted at ten screening centers in the US...

OBJECTIVE: To assess the longitudinal behavior of Quantitative Lung Index (QLI) for the follow-up of fetuses with congenital diaphragmatic hernia. STUDY DESIGN: Retrospective study of fetuses with isolated left congenital diaphragmatic hernia. The fetuses were assessed by ultrasound at different gestational ages and QLI was retrospectively calculated by means of previous lung-to-head ratio measurements. We used a random effects model (mixed model with repeated measurements) to compare the performance of the QLI in operated and non-operated fetuses throughout pregnancy...
