Endobronchial ultrasound-guided needle aspiration (EBUS-TBNA) is a well-established procedure with high diagnostic yield and safety. However, the standard 22 gauge needles sometimes cause major bleeding particularly in hypervascular tumors like metastatic lung tumors from renal cell carcinoma (RCC). The 25 gauge needles are already introduced to endoscopic ultrasound-guided fine needle aspiration (EUS-FNA), and are considered as one of the standard devices due to their comparable diagnostic outcome, lower complication risk, and the better manipulability...

Tracheobronchial foreign body (FB) aspiration is an uncommon but potentially life-threatening event in adults. Symptoms typically consist of a choking event followed by cough and dyspnea, however, these findings are inconsistent and symptoms may mimic more chronic lung diseases such as asthma or chronic obstructive pulmonary disease. Chest radiography and computed tomography can provide information regarding the location and characteristics of foreign bodies and aid in diagnosis. Bronchoscopy remains the gold standard for diagnosis and management of FB aspiration...

Earlier work form this laboratory showed that exposure of alveolar epithelial cells (AECs) to meconium caused significant cell detachment and that meconium-induced detachment of cells was prevented by a protease inhibitor cocktail. Therefore, it was hypothesized that protease inhibitors might protect AEC monolayers against meconium-induced collapse of epithelial barrier function both in vitro and in vivo. To investigate this theory in vitro, albumin flux was measured across cultured, confluent monolayers of human type II derived cell line A549 on microporous filter inserts...

BACKGROUND: The post-thrombotic syndrome frequently develops in patients with proximal deep-vein thrombosis despite treatment with anticoagulant therapy. Pharmacomechanical catheter-directed thrombolysis (hereafter "pharmacomechanical thrombolysis") rapidly removes thrombus and is hypothesized to reduce the risk of the post-thrombotic syndrome. METHODS: We randomly assigned 692 patients with acute proximal deep-vein thrombosis to receive either anticoagulation alone (control group) or anticoagulation plus pharmacomechanical thrombolysis (catheter-mediated or device-mediated intrathrombus delivery of recombinant tissue plasminogen activator and thrombus aspiration or maceration, with or without stenting)...

BACKGROUND: Indirect evidence suggests that sinonasal secretions are aspirated into the lungs of patients with cystic fibrosis (CF), contributing to infection, subsequent tissue damage, and decreased lung function. Our objective is to determine whether sinonasal secretions are transferred to the lungs in patients with CF-related sinus disease and healthy subjects, particularly in the recumbent position and during sleep. METHODS: We performed a prospective, controlled trial to detect pulmonary aspiration of radiolabeled albumin applied to the nasal mucosa of study subjects with chronic sinusitis related to CF and control subjects without sinus disease...

Background: Ventilator-induced lung injury is considered to be a main factor in the pathogenesis of bronchopulmonary dysplasia (BPD). Optimizing ventilator strategies may reduce respiratory morbidities in preterm infants. Permissive hypercapnia has been suggested to attenuate lung injury. We aimed to determine if a higher PCO2 target range results in less lung injury compared to the control target range and possibly reduces pro-inflammatory cytokines and acid sphingomyelinase (ASM) in tracheal aspirates (TA), which has not been addressed before...

Salivary duct carcinoma (SDC) is an aggressive form of salivary gland tumor, and SDC patients tend to be older men, more commonly in advanced stage with a poorer prognosis. Although the cytological characteristics of SDC on fine-needle aspiration cytology have been well-described at the primary site, they have not been explored in metastasis. Here we reported a case of HER2/HER3-positive metastatic SDC in the lung and pleural effusion. The patient was a man in his 50s who had undergone extended total parotidectomy in 2008...

Purpose: To validate the accuracy of previously published equations that estimate pleural effusion volume using ultrasonography. Methods: Only equations using simple measurements were tested. Three measurements were taken at the posterior axillary line for each case with effusion: lateral height of effusion (H), distance between collapsed lung and chest wall (C) and distance between lung and diaphragm (D). Cases whose effusion was aspirated to dryness were included and drained volume was recorded...

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has increasingly been performed for the diagnosis and staging of thoracic malignancies. Findings of a necrotic lymph node raise concern for infectious process and malignancy. A hypoechoic area on ultrasound/EBUS within a lymph node without blood flow is suggestive of pathologies like infections or malignancy. Inspection of the fluid could suggest a diagnosis; clear aspirates usually suggest bronchogenic or mediastinal cysts and purulent material suggests abscesses or necrotic lymph nodes...

BACKGROUND: Invasive aspergillosis (IA) is a rare condition that generally affects immunosuppressed patients. The mortality of IA is known to be >90% in liver transplantation (LT) recipients; the lung is the most commonly affected organ, followed by the brain. There have been reports in the literature of cerebral aspergillosis (CA) in LT recipients. In all previous reports, CA developed after LT. We present the first case (to the best of our knowledge) of preexisting CA diagnosed and successfully treated after LT...

Diesel is commonly used as fuel for engines and is distilled from petroleum. Diesel has toxic potential and can affect multiple organs. Exposure can occur after ingestion, inhalation or through the dermal route. The practice of siphoning diesel using a rubber tubing and the mouth is common in rural communities. This can lead to accidental ingestion and aspiration. Here we report a case of a patient who accidentally ingested diesel during siphoning, which caused extensive erosion of the oral cavity and oesophagus leading to pneumomediastinum and severe chemical lung injury...

INTRODUCTION: S-1 is an oral fluoropyrimidine-based combination of tegafur, gimeracil, and oteracil potassium. Although the combination of S-1 with carboplatin is a first-line chemotherapy regimen for advanced non-small cell lung cancer (NSCLC), the efficacy and safety of the regimen in the elderly remain unknown. METHODS: The patient inclusion criteria were previously untreated advanced NSCLC, wild-type epidermal growth factor receptor, aged 70 years or more, and a performance status (PS) of 0-2...

BACKGROUND: Immunohistochemical (IHC) assessment of programmed death-ligand 1 (PD-L1) in non-small cell lung cancer (NSCLC) has become important since the development of anti-PD-1/-PD-L1 directed drugs. Various PD-L1 antibodies and cut-offs have been used in different trials to predict response to these drugs, thus comparison of those studies is difficult. We compared PD-L1 mRNA expression measured by RT-qPCR with PD-L1 protein expression evaluated by IHC. Moreover, we investigated the impact of different tumour tissue acquisition methods on the reliability of PD-L1 measurement techniques...

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has been widely used for diagnosis and mediastinal lymph nodes staging in patients with suspicious lung cancer. Ultrasound elastography is a novel sonographical technique that can evaluate tissue compressibility. The aim of the present study was to investigate the diagnostic yield of elastography for differentiating malignant and benign mediastinal lymph nodes. Conventional EBUS B-mode features, including size, shape, border distinction, echogenicity, central hilar structure with central blood vessel and coagulation necrosis were also evaluated...

BACKGROUND: Thyroid cancer is the most prevalent endocrine malignancy, and the incidence of thyroid cancer has increased worldwide. Fine needle aspiration (FNA) for cytology of thyroid tissue is used for differentiating thyroid cancers from benign thyroid nodules. Overuse of FNA may detect subclinical thyroid cancer and play a role in the increased incidence of thyroid cancer. The aim of this study was to evaluate trends in incidence of thyroid cancer and the use of palpation-guided FNA thyroid and ultrasound-guided FNA thyroid in Taiwan...

BACKGROUND: The microbiota of the bovine upper respiratory tract has been recently characterized, but no data for the lower respiratory tract are available. A major health problem in bovine medicine is infectious bronchopneumonia, the most common respiratory syndrome affecting cattle. With this study, we used 16S rRNA gene sequencing to characterize and compare the microbial community composition of the upper and lower respiratory tracts in calves. RESULTS: The microbiota of the upper (nasal swab [NS]) and the lower (trans-tracheal aspiration [TTA]) respiratory tracts of 19 post-weaned Piedmontese calves with (8/19) and without (11/19) clinical signs of respiratory disease, coming from six different farms, was characterized by 16S rRNA gene metabarcoding...

BACKGROUND: Mechanisms that elicit mucosal Th17 cell responses have been described, yet how these cells are sustained in chronically inflamed tissues remains unclear. OBJECTIVE: We sought to understand whether the maintenance of lung Th17 inflammation requires environmental agents in addition to antigen, and to identify the lung antigen-presenting cell types (APCs) that sustain the self-renewal of Th17 cells. METHODS: Animals were repeatedly exposed to aspiration of ovalbumin alone, or together with environmental adjuvants, including extracts of common house dust (HDE), to test their role in maintaining lung inflammation...

BACKGROUND: Donohue syndrome is a rare autosomal recessive disorder of insulin resistance, causing a functional defect in insulin receptor function, and affecting the ability of the insulin to bind the receptor. Features include severe hyperinsulinism and fasting hypoglycemia, along with severe failure to thrive despite feeding. An accelerated fasting state results in muscle wasting, decreased subcutaneous fat, and an excess of thick skin. A reduced thoracic diameter is accentuated by increased abdominal distension, which impacts on respiratory reserve...
