BACKGROUND Weight loss in cystic fibrosis (CF) may be associated with altered levels of appetite stimulating peptide ghrelin and the appetite decreasing peptide leptin. However, prior data on leptin in CF are conflicting, while the data on ghrelin are scarce. We hypothesized that weight loss in CF is associated with low levels ghrelin and elevated levels of(More)
BACKGROUND DVT is common among critically ill patients. A rapid and accurate diagnosis is essential for patient care. We assessed the accuracy and timeliness of intensivist-performed compression ultrasonography studies (IP-CUS) for proximal lower extremity DVT (PLEDVT) by comparing results with the formal vascular study (FVS) performed by ultrasonography(More)
Thoracic ultrasonography is a noninvasive and readily available imaging modality that has important applications in pulmonary medicine outside of the ICU. It allows the clinician to diagnose a variety of thoracic disorders at the point of care. Ultrasonography is useful in imaging lung consolidation, pleural-based masses and effusions, pneumothorax, and(More)
BACKGROUND To compare the complication rates of urgent endotracheal intubation (UEI) performed by pulmonary critical care medicine (PCCM) fellows and attending intensivists using a direct laryngoscope (DL) versus a video laryngoscope (VL) in a medical intensive care unit (MICU). METHODS We studied all UEIs performed from November 2008 through July 2012 in(More)
Aspiration of gastric contents is a dangerous complication of urgent endotracheal intubation (UEI). Left upper quadrant (LUQ) ultrasonography may have the potential to decrease this complication by identifying patients with gastric fluid content, thereby allowing the UEI team to evacuate gastric contents prior to intubation. This was an observational study(More)
PURPOSE Propofol is known to provide excellent intubation conditions without the use of neuromuscular blocking agents. However, propofol has adverse effects that may limit its use in the critically ill patients, particularly in the hemodynamically unstable patient. We report on the safety and efficacy of propofol for use as an agent for urgent endotracheal(More)
We report the case of a 58-year-old man on chronic steroid therapy, who developed a rapidly progressive right upper lobe infiltrate/mass that extended into the right hilum. Respiratory failure necessitated endotracheal intubation. Broad spectrum antibiotics were initiated without clinical improvement and because of his immunosuppressive therapy(More)
This is a retrospective study of 48 patients who underwent EBUS-TBNA procedure between the periods January 2008 to September 2009 at Long Island Jewish Medical Center. The study was undertaken with the following objectives: First, to define practical and useful on-site adequacy criteria for EBUS-TBNA samples; Second, to understand the diagnostic pitfalls(More)
Aldosterone has long been known to mediate water and electrolyte balance by acting on mineralocorticoid receptors in the kidneys. However, recent studies have demonstrated the presence of these receptors in nonclassical locations, including the brain, blood vessels, and the heart. This finding suggests that aldosterone may play a larger role than once(More)
BACKGROUND Point-of-care ultrasonography performed by frontline intensivists offers the possibility of reducing the use of traditional imaging in the medical ICU (MICU). We compared the use of traditional radiographic studies between two MICUs: one where point-of-care ultrasonography is used as a primary imaging modality, the other where it is used only for(More)
