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...

In the everyday practice of respiratory physicians, ultrasound techniques play a key role by enabling several diagnostic and interventional procedures. The application of ultrasound to endoscopic procedures allows both a visualization and a guided sampling of mediastinal and hilar lymph nodes. Endobronchial ultrasound can be combined with transbronchial needle aspiration, and, similarly, endoscopic ultrasound can be combined with fine-needle aspiration to sample virtually all mediastinal nodal stations from the airways and the esophagus...

Background: Prolonged pyrexia and weight loss are recognised paraneoplastic manifestations of renal cell carcinoma (RCC). Stauffer's syndrome is a rarely described paraneoplastic manifestation, which is described early in the course of RCC. We report a patient who presented with unresolving fever with multiple pulmonary opacities with biochemical evidence of hepatic choleastasis and was later diagnosed to have metastatic RCC with Stauffer's syndrome. Case Presentation: We report a 54-year-old female who was investigated for a poorly resolving fever and recent weight loss for two months...

BACKGROUND: Routine lung cancer surveillance has resulted in early detection of pulmonary nodules and masses. Combined endobronchial ultrasound (EBUS) and trans-esophageal endoscopic ultrasound (EUS) are approved methods for sampling lymph nodes or masses. Furthermore, EUS allows for adrenal sampling as part of staging, and can assist with fiducial placement for stereotactic body radiation therapy (SBRT). OBJECTIVES: Promote use of EUS by interventional pulmonologists in the United States when diagnosing and staging lung cancer or when placing fiducials...

INTRODUCTION: In Duchenne muscular dystrophy (DMD) the assessment of diaphragmatic function is crucial because respiratory muscle weakness can cause respiratory failure. We aimed to noninvasively assess diaphragmatic function in DMD by measuring diaphragmatic thickness by ultrasonography, under the hypothesis that the progressive decrease of lung function is related to alterations of diaphragmatic thickness. METHODS: Forty-four DMD patients and thirteen healthy controls were enrolled and subdivided into three age groups...

The aim of present study was to investigate the diagnostic accuracy of ultrasonography features for the detection of mild pneumothorax using CT in dogs. Nine adult healthy beagles were included in the study. The thoracic tube was inserted into pleural space at the left thoracic wall. All dogs underwent the examinations in the order of CT, lung ultrasound, and radiography examinations before the infusion of room air into the pleural space. Typically, 2, 3 (total 5 ml/kg), and 5 ml/kg (total 10 ml/kg) of room air was sequentially infused into the pleural space and CT, lung ultrasound, and radiography examinations were performed, respectively...

BACKGROUND: Transient tachypnea of the newborn (TTN) is one of the most common causes of neonatal respiratory distress (RD). However, distinguishing TTN from other causes of RD may be difficult during the first 12:24 h after birth. Lung ultrasonography (LUS) has been successfully utilized in the diagnosis and differential diagnosis of neonatal RD. This study aimed to investigate the diagnostic value of LUS for early diagnosis of TTN as well as differentiate it from other causes of neonatal RD in near and full term Egyptian neonates...

OBJECTIVES: Point-of-care lung ultrasonography (US) is an alternative to chest radiography for imaging of suspected community-acquired pneumonia (CAP) in children. We compared pediatric emergency department (ED) time metrics between children who received point-of-care lung US versus chest radiography. Secondary objectives were comparisons of health system costs and other resources in these imaging groups. METHODS: This work was a retrospective matched cohort study of children aged 0 to 18 years in an academic urban pediatric ED who were imaged for suspected CAP with either point-of-care lung US or chest radiography...

Comparing diagnostic accuracy study between ultrasonography (US) guided fine-needle aspiration biopsy (FNAB) and core-needle biopsy (CNB) of the Sentinel lymph nodes (SLNs) in newly diagnosed invasive breast cancer patients. We selected 289 newly diagnosed invasive breast cancer patients from June 2015 to July 2017. Ultrasound (US) guided fine-needle aspiration cytology (FNA) and core-needle biopsy (CNB) was performed to identify patients with suspicious sentinel lymph node (SLN). Patients with a cortical thickness > 2 mm or atypical morphological characteristics were recommended FNA and CNB...

BACKGROUND: Before total body computed tomography scan, an initial rapid imaging assessment should be conducted in the trauma bay. It generally includes a chest x-ray, pelvic x-ray, and an extended focused ultrasonography assessment for trauma. This initial imaging assessment has been poorly described since the increase in the use of ultrasound. Therefore, our study aimed to evaluate the diagnostic accuracy and therapeutic impact of this initial imaging work-up in severe trauma patients...

Lung abscess is usually treated with long-term antibiotic therapy. Due to the lack of a safe and easy drainage technique, drainage is only applied in refractory cases. We herein describe three cases in which drainage was successfully performed by endobronchial ultrasonography using a modified guide sheath. This procedure may have advantages in the detection of causative pathogens and early infection source control, and may therefore lead to the appropriate selection of antibiotics and reduce the duration of antibiotic therapy...
