INTRODUCTION: Many extrathoracic malignancies can metastasize to lungs and mediastinal lymph nodes. Whether mediastinal lesions are metastasis in these patients changes staging, prognosis, and treatment strategy. In this study, we aimed to find out the contribution of EBUS-TBNA to the diagnosis in cases with extrathoracic malignancy. MATERIALS AND METHODS: Patients who had been previously diagnosed as extrapulmonary solid organ malignancy and in whom mediastinal or hilar lymphadenopathy developed during their follow-up and EBUS-TBNA was applied for diagnostic purposes were retrospectively included in this study...

Ultrasound examination of the chest has advanced in recent decades. This imaging modality is currently used to diagnose several pathological conditions and provides qualitative and quantitative information. Acoustic barriers represented by the aerated lungs and the bony framework of the chest generate well-described sonographic artifacts that can be used as diagnostic aids. The normal pleural line and A, B, C, E and Z lines (also known as false B lines) are artifacts with specific characteristics. Lung consolidation and pneumothorax sonographic patterns are also well established...

We report the case of a 55-year-old man with stage IV lung adenocarcinoma who received carboplatin-paclitaxel-bevacizumab chemotherapy as second-line therapy. After four cycles of chemotherapy, he experienced syncope with a decrease in blood pressure. Electrocardiography (ECG) revealed atrial fibrillation. Cardiac ultrasonography showed a markedly reduced ejection fraction (45%), with moderate decrease in comparison to that before chemotherapy (66%). Bisoprolol fumarate was initiated, and the conversion to sinus rhythm was detected by ECG 4 days after the syncope...

Contrast-enhanced ultrasound is a valuable and safe technique for the evaluation of organ perfusion. Repeated injections of ultrasound contrast agent are often administered during the same imaging session. However, it remains unclear if quantitative differences are present between the consecutive microbubble injections. Therefore, the first and second injection of contrast agent for the left renal cortex, renal medulla and the splenic parenchyma in healthy cats were compared. A lower peak intensity and area under the curve were observed for the first injection of contrast agent in the feline kidney, both for the renal cortex and medulla, and spleen...

Rheumatoid arthritis (RA) is an inflammatory autoimmune disease that can present different extrarticular manifestations involving heart, lungs and kidneys. In recent years there has been a growing awareness of the central role played by the lungs in the onset and progression of RA. In particular interstitial lung disease (ILD) is a common pulmonary manifestation that may be related to the inflammatory process itself, infectious complications and to the treatments used. Management of patients with ILD/RA is still a challenge for clinicians, both synthetic [mainly methotrexate (MTX), leflunomide] and biologic immunosuppressors [mainly anti-tumor necrosis factor (TNF)α] have in fact been related to the onset or worsening of lung diseases with conflicting data...

Extrapulmonary tuberculosis refers to Mycobacterium tuberculosis involving organs other than the lungs (eg, pleura, lymph nodes, genitourinary tract, abdomen, skin, joints and bones, or meninges). In non-HIV-endemic areas, where reactivation is the predominant mechanism of tuberculosis, pleural involvement occurs in 4% of cases. We present an extremely rare case of a 62-year-old immunocompetent patient with pleural tuberculosis confirmed by surgical pleural biopsies, who presented with a large mediastinal mass and evidence of pulmonary artery invasion on CT scanning and endobronchial ultrasonography imaging, highlighting a unique and malignant-like character of the disease...

BACKGROUND: Platelet count (PC) and fatty liver are both associated with metabolic syndrome (MS), obesity, and type 2 diabetes. While PC increases in obesity and type 2 diabetes, the severity of hepatic fibrosis caused by fatty liver reduces PC. We aimed to investigate the correlation of PC and MS in patients with and without fatty liver. METHODS: We enrolled consecutive patients who received health check-ups at Taipei Veterans General Hospital from 2002 to 2009...

BACKGROUND AND OBJECTIVES: There is a lack of evidence concerning associations between novel parameters of arterial stiffness as cardiovascular risk markers and traditional structural and functional vascular biomarkers in a population-based Caucasian cohort. We examined these associations in the second follow-up of the Swiss Cohort Study on Air Pollution and Lung and Heart Diseases in Adults (SAPALDIA 3). METHODS: Arterial stiffness was measured oscillometrically by pulse wave analysis to derive the cardio-ankle vascular index (CAVI), brachial-ankle (baPWV) and aortic pulse wave velocity (aPWV), and amplitude of the forward and backward wave...

INTRODUCTION: The ability to judge intravascular volume is fundamental in the management of patients with severe preeclampsia. Insufficient intravascular volume can result in decreased oxygen delivery to tissues and exacerbates organ dysfunction. On the other hand, fluid excesses can lead to fluid extravasation and pulmonary edema. Outside of pregnancy, transthoracic echocardiography and lung ultrasonography have become important diagnostic and monitoring tools in critically ill patients...

In the era of evidence-based medicine, ultrasonography has emerged as an important and indispensable tool in clinical practice in various specialties including critical care. Lung ultrasound (LUS) has a wide potential in various surgical and clinical situations for timely and easy detection of an impending crisis such as pulmonary edema, endobronchial tube migration, pneumothorax, atelectasis, pleural effusion, and various other causes of desaturation before it clinically ensues to critical level. Although ultrasonography is frequently used in nerve blocks, airway handling, and vascular access, LUS for routine intraoperative monitoring and in crisis management still necessitates recognition...

BACKGROUND: Patients with persistent N2 disease after induction have poor survival. Many of these patients may have had mediastinoscopy before induction therapy, making reassessment of the mediastinum by repeat mediastinoscopy hazardous and inaccurate. The sensitivity and specificity of endobronchial ultrasonography and nodal fine-needle aspiration in this setting is unclear. In this study, we sought to identify the clinical predictors of persistent N2 disease after induction therapy, which may help in selecting the patients most likely to benefit from surgical resection...

BACKGROUND AND OBJECTIVE: Diaphragm function might be useful to predict nocturnal oxygen desaturation in COPD. Ultrasonography has been widely used for the assessment of the diaphragm. We aimed to investigate the relationship between the contractile capability of the diaphragm assessed by ultrasonography and the nocturnal percutaneous arterial oxygen saturation (NSpO2 ) in COPD. METHODS: Twenty-eight male patients with COPD (age, 73 ± 7 years; forced expiratory volume in 1 s (FEV1 ), 54...

Contrast-enhanced Ultrasound (CEUS) represents a complementary technique to grey-scale and colour Doppler ultrasonography (US) which allows for real-time visualization and characterization of tissue perfusion. Its inherent advantages in the child makes US an ideal imaging modality; repeatability and good tolerance along with the avoidance of computed tomography (CT), a source of ionizing radiation, renders US imaging desirable. Although currently paediatric CEUS is principally used in an "off-label" manner, US contrast agents have received regulatory approval for assessment of paediatric focal liver lesions in the United States of America...

Diffuse alveolar haemorrhage (DAH) leads to acute respiratory failure. This is why it requires rapid diagnosis and implementation of appropriate treatment. The standard diagnosis of a patient with DAH includes laboratory tests, diagnostic imagining (X-ray of the chest, high-resolution computed tomography), and bronchoscopy with bronchoalveolar lavage. We present a description of 2 patients diagnosed with systemic connective tissue disease and DAH, monitored with the help of lung ultrasound. To our knowledge, this is the first description of the use of lung ultrasound in DAH in adult patients...

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract and usually occur in the stomach and the small intestine. The pancreas is an extremely rare primary site for GISTs and there are 25 reported cases of pancreatic GIST with most being treated with surgical resection. We describe a 52-year-old African-American female who was diagnosed with limited stage small cell carcinoma in November 2009 and treated with concurrent cisplatin/etoposide chemotherapy and radiation...

Since the development of portable ultrasonography equipment, this technology has provided clinicians the ability to evaluate a variety of lung pathology at the bedside, but we are still learning how to accurately interpret the acquired images. Adequate interpretation and recognition of certain signs is crucial to diagnosing pathological processes. In addition, such signs must be adequately correlated with the patient's medical condition. For instance, the "lung point sign" has been traditionally considered to be pathognomonic for the presence of a pneumothorax, yet such finding may be present in patients with bullous lung disease without a pneumothorax...
