Inflammatory myofibroblastic tumor (IMT) is an uncommon neoplasm that has been described in various locations throughout the body, but is rarely observed in systemic lymph nodes. We present a case of a 63 years old woman with left inguinal lymphadenopathy accompanied by low-grade fever. Fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18 F-FDG PET/CT) revealed abnormal higher18 F-FDG uptake on the neck, axillar, pulmonary hilar, mediastinal, mesenteric, retroperitoneal, pelvic and inguinal lymph nodes...

Postoperative pulmonary complications are common after cardiothoracic surgery and are associated with adverse outcomes. The ability to detect postoperative pulmonary complications using chest X-rays is limited, and this technique requires radiation exposure. Little is known about the diagnostic accuracy of lung ultrasound for the detection of postoperative pulmonary complications after cardiothoracic surgery, and we therefore aimed to compare lung ultrasound with chest X-ray to detect postoperative pulmonary complications in this group of patients...

A retrospective study was carried out to evaluate the diagnostic accuracy and the factors influencing the diagnostic accuracy of 648 procedures of ultrasound-guided percutaneous needle biopsy (PNB) for peripheral pulmonary lesions (PPLs). We reviewed the histopathology results, the clinical records and the procedure reports of these 648 biopsies and the final diagnoses of 637 PPLs to determine the diagnostic accuracy of ultrasound-guided PNB. Factors that influenced the diagnostic accuracy were assessed by analysis of the biopsy procedures, which were classified as diagnostic cases (true-positive and true-negative) and non-diagnostic cases (false-positive, false-negative and indeterminate)...

BACKGROUND: Right ventricular peak systolic longitudinal strain (RVLS) has emerged as an approach for quantifying right ventricular function in diseases such as pulmonary hypertension and congenital heart disease. A major limitation in applying RVLS is that strain imaging and analysis are proprietary, which may result in systematic differences from vendor to vendor. The goal of this study was to test the reproducibility of right ventricular strain analysis among selected vendor-specific software (VSS) and vendor-independent software (VIS) on images obtained from different ultrasound scanners, as would be common in clinical practice or in a multicenter clinical trial...

BACKGROUND: Sclerosing pneumocytoma is a rare lung tumor that is usually recognized as a solitary nodule in the lung. Surgical removal is recommended; however, its clinical diagnosis is still an issue because it is difficult to differentiate from lung adenocarcinomas using a tiny sample obtained from biopsy. CASE PRESENTATION: We report a case of pulmonary sclerosing pneumocytoma located in the upper lobe of the right lung of a 34-year-old woman, which was diagnosed before surgery by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA)...

INTRODUCTION: A significant increase of the p-wave of a real-time intracavitary electrocardiography is a reliable and safe method to confirm the central venous catheter tip position close to the atrium. However, conflicting data about the feasibility of electrocardiography exist in patients with atrial fibrillation. METHODS: An observational prospective case-control cohort study was set up to study the feasibility and accuracy of the electrocardiography-controlled central venous catheter tip placement in 13 patients with atrial fibrillation versus 10 patients with sinus rhythm scheduled for elective surgery...

Deep vein thrombosis is a common vascular disease that can lead to pulmonary embolism and death. The early diagnosis and clot age staging are important parameters for reliable therapy planning. This article presents an acoustic radiation force induced resonance elastography method for the viscoelastic characterization of clotting blood. The physical concept of this method relies on the mechanical resonance of the blood clot occurring at specific frequencies. Resonances are induced by focusing ultrasound beams inside the sample under investigation...

Preterm birth prematurely exposes the immature heart to the haemodynamic transition at birth, which has the potential to induce abnormal cardiac remodelling. Magnetic resonance imaging studies in young adults born preterm have shown abnormalities in the gross structure of the ventricles (particularly the right ventricle; RV), but the cellular basis of these alterations is unknown. The aim of this study, conducted in sheep, was to determine the effect of moderate preterm birth on RV cellular structure and function in early adulthood...

A 71-year-old man, who had received long-term oxygen therapy for respiratory failure caused by chronic obstructive pulmonary disease, had an enlarged mediastinal lymph node for one year. As his lung function was poor, we tried performing endobronchial ultrasound-guided transbronchial needle aspiration under non-invasive positive pressure ventilation for diagnosis but could not obtain sufficient specimens. Later, we performed an endoscopic ultrasound with bronchoscope-guided fine-needle aspiration (EUS-B-FNA) using a transesophageal approach...

RATIONALE: Although an inferior vena cave (IVC) filter is placed to prevent fatal pulmonary embolism (PE), several complications associated with an IVC filter have been reported. We describe a case with symptomatic PE, of which the origin was an occlusive IVC thrombus that developed from the placement of an IVC filer after a laparoscopy-assisted total gastrectomy (LATG). PATIENT CONCERNS: A 71-year-old man underwent LATG under general anesthesia alone. He had an IVC filter implanted 13 years ago...

Assessment and treatment of the VLBW infant with cardiovascular impairment requires understanding of the underlying physiology of the infant in transition. The situation is dynamic with changes occurring in systemic blood pressure, pulmonary pressures, myocardial function, and ductal shunt in the first postnatal days. New insights into the role of umbilical cord clamping in the transitional circulation have been provided by large clinical trials of early versus later cord clamping and a series of basic science reports describing the physiology in an animal model...

BACKGROUND: Effects of hypobaric hypoxia at altitude on exercise performance of lowlanders with chronic obstructive pulmonary disease (COPD) have not been studied in detail. OBJECTIVES: To quantify changes in exercise performance and associated physiologic responses in lowlanders with COPD travelling to moderate altitude. METHODS: A total of 31 COPD patients with a median age (quartiles) of 66 years (59; 69) and FEV1 of 56% predicted (49; 69) living below 800 m performed a constant-load bicycle exercise to exhaustion at 60% of the maximal work rate at 490 m (Zurich) and at an identical work rate at 2,590 m (Davos) in randomized order...

BACKGROUND: Although pulmonary congestion can be quantified by lung ultrasonography (LUS) in heart failure (HF), little is known about LUS findings (B-lines) in different HF phenotypes. This prospective cohort study investigated the prevalence, clinical and echocardiographic correlates of B-lines in ambulatory HF patients with preserved (HFpEF) or reduced ejection fraction (HFrEF) compared with hypertensive patients. We related LUS findings to 12-month HF hospitalizations and all-cause mortality...

Bedside ultrasound is often used as a part of the evaluation of patients who are critically ill. The McConnell sign is an important echocardiographic finding in some critically ill patients with pulmonary embolism and an acute right ventricular infarct. We present 3 critically ill patients with confirmed acute chest syndrome who showed the McConnell sign on echocardiography. In patients with sickle cell disease presenting with chest pain and shortness of breath, the presence of the McConnell sign does not narrow the differential diagnosis between pulmonary embolism, an acute right ventricular infarct, and acute chest syndrome...

Explantation of a left ventricular assist device (LVAD) may be challenging even in the most experienced hands. We aim to describe the technique for explantation of an LVAD together with the heart as applicable to all contemporary implantable mechanical assist devices. In order to ensure safe explantation, particular care must be taken at three distinct stages: at the time of LVAD implantation, at pre-transplant assessment and at the time of heart transplantation. The preparation for a safe explantation at LVAD implantation includes positioning the driveline and the outflow graft away from the back of the sternum to ensure protection from injury during re-entry into the chest...
