OBJECTIVE: The intent of fluid bolus therapy (FBT) is to increase cardiac output and tissue perfusion, yet only 50% of septic children are fluid responsive. We evaluated respiratory variation of inferior vena cava (IVC) diameter as a predictor of fluid responsiveness. METHODS: A prospective observational study in the ED of The Royal Children's Hospital, Melbourne, Australia. Patients were spontaneously ventilating children treated with FBT for sepsis-induced acute circulatory failure...

Despite its popularity, ultrasound (US)-guided regional anesthesiology is associated with significant limitations. The latter can be attributed to either the US machine (ie, decreased ability to insonate deep neural structures, as well as the thoracic spine) or the operator. Shortcomings associated with the operator can be explained by errors in perception (ie, ambiguous criteria for needle/catheter tip-to-nerve proximity and subparaneural local anesthetic injection) or interpretation. Perhaps the greatest confusion afflicting US-guided regional anesthesiology originates from an intellectual misconception pertaining to its application...

In the past decade, there has been significant progress in clinical hematology with the discovery of targeted molecules and thus the achievement of both hematologic and molecular responses. Nevertheless, chemotherapy remains the treatment of choice for many types of hematological malignancies. Aggressive chemotherapy leads to immunosuppression, accompanied by a high rate of infections and an increased rate of treatment-related mortality. Invasive fungal infections as well as more common bacterial and viral infections are frequent in immunocompromised patients as they are difficult to diagnose and treat...

OBJECTIVE: Patients with type II diabetes (T2DM) are at 2-3 fold excess risk of heart failure. Its prevention and treatment are poor. Here we tested the hypothesis that spironolactone, perhaps by limiting myocardial fibrosis, and inorganic nitrate, which acutely affects myocardial dynamics, would improve cardiac structure and function beyond effects of blood pressure (BP) in these patients. DESIGN AND METHOD: 104 patients with or at risk of T2DM participated in a factorial design, double blind, randomised controlled trial (VaSera)...

PURPOSE OF REVIEW: Peripheral pulmonary lesions (PPL) are being diagnosed with increasing frequency, especially with the increased use of chest computed tomography (CT). Depending on the location and size, these lesions often present a diagnostic challenge in terms of the low yield of traditional bronchoscopic biopsy techniques or the risks of a percutaneous biopsy approach. RECENT FINDINGS: Over the last several years, several different image-guided bronchoscopy techniques have emerged, including virtual bronchoscopic navigation, electromagnetic navigation bronchoscopy, radial endobronchial ultrasound, and ultrathin bronchoscopy...

BACKGROUND AND OBJECTIVES: Compared with the thoracic and lumbar spine, transforaminal epidural injections and medial branch blocks in the cervical spine are associated with a higher incidence of neurological complications. Accidental breach of small periforaminal arteries has been implicated in many instances. In this observational study, using ultrasonography, we surveyed the incidence of periforaminal bloods vessels in the cervical spine. METHODS: Patients undergoing ultrasound-guided cervical medial branch blocks were scanned using color power and pulsed wave Doppler...

BACKGROUND: Utilisation of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and guide sheath (EBUS-GS) for diagnosis and staging of lung cancer is gaining popularity, however, its impact on clinical practice is unclear. This study aimed to determine the impact of the introduction of endobronchial ultrasound-guided procedures (EBUS) on time to management decision for lung cancer patients, and on the utilisation of other invasive diagnostic modalities, including CT-guided trans-thoracic needle aspiration (CT-TTNA), bronchoscopy, and mediastinoscopy...

Accumulating evidence suggests that nonalcoholic fatty liver disease (NAFLD) is associated with left ventricular diastolic dysfunction (LVDD) in nondiabetic individuals. To date, there are very limited data on this topic in patients with type 2 diabetes and it remains uncertain whether NAFLD is independently associated with the presence of LVDD in this patient population. We performed a liver ultrasonography and trans-thoracic echocardiography (with speckle-tracking strain analysis) in 222 (156 men and 66 women) consecutive type 2 diabetic outpatients with no previous history of ischemic heart disease, chronic heart failure, valvular diseases and known hepatic diseases...

Emerging clinical data support the notion that RV dysfunction is critical to the pathogenesis of cardiovascular disease and heart failure(1-3). Moreover, the RV is significantly affected in pulmonary diseases such as pulmonary artery hypertension (PAH). In addition, the RV is remarkably sensitive to cardiac pathologies, including left ventricular (LV) dysfunction, valvular disease or RV infarction(4). To understand the role of RV in the pathogenesis of cardiac diseases, a reliable and noninvasive method to access the RV structurally and functionally is essential...

The cardiorenal syndrome (CRS) indicates how close the relationship is between heart and kidney during failure of these organs. At present, the classification of the syndrome includes five types of CRS: types I and II which are strictly related to initial heart failure (both acute and chronic), types III and IV which include initial kidney failure, and type V which includes several systemic diseases. Many pathophysiological pathways have been described illustrating how heart and kidney disease are involved in clinical conditions...
