Introduction: Humidity is commonly associated with increased airway hyperresponsiveness in asthma. Objective: To examine mold sensitization in patients with allergic asthma or allergic rhinitis and self-reports of humidity as exacerbating factors of…
Although sarcoidosis has clinical and histopathologic similarities to some forms of tuberculosis and other mycobacterial infections, attempts to establish a mycobacterial etiology have not been successful. Using cytoplasmic antigens derived from a…
Protriptyline is the pharmacologic agent most commonly used to treat obstructive sleep apnea (OSA); however, its anticholinergic side effects make it intolerable to many patients. Because serotonin may be a central respiratory stimulant and because…
Asia is a highly heterogeneous region with vastly different cultures, social constitutions and populations affected by a wide spectrum of respiratory diseases caused by tropical pathogens. Asian patients with community-acquired pneumonia differ from…
Study objective: To measure the in vivo rate of alveolar epithelial fluid clearance of the human lung in patients with pulmonary alveolar phospholipoproteinosis (PAP). Design: Prospective clinical study. Setting: The medical-surgical ICUs of a…
Some investigators have reported that endogenous beta-adrenoceptor tone can provide protection against acute lung injury. Therefore, we tested the effects of beta-adrenoceptor inhibition in mice with acute Escherichia coli pneumonia. Mice were…
Objective: Investigation of the hypothesis that the infusion of 10 ng/kg/min prostacyclin (epoprostenol) (PGI(2)) improves O-2 uptake in patients with hyperdynamic septic shock. Design: Prospective, single cohort design. Setting: ICU, university…
Study objective: To review the clinical and laboratory findings in a large number of patients with pneumococcal bacteremia in the 1980s and identify risk factors associated with increased mortality. Design: Retrospective review of medical records…
Kooijman EE, Kuzenko SR, Gong D, Best MD, Folkesson HG. Phosphatidylinositol 4,5-bisphosphate stimulates alveolar epithelial fluid clearance in male and female adult rats. Am J Physiol Lung Cell Mol Physiol 301: L804-L811, 2011. First published…
Hyperoxic ventilation, used to prevent hypoxemia during potential periods of hypoventilation, has been reported to paradoxically decrease whole body oxygen consumption (Vo(2)). Reduction in nutritive blood flow due to oxygen radical production is one…
Methacholine challenge testing (MCT), also sometimes described as bronchoprovocation testing, is widely performed for both research and diagnostic purposes. MCT is clinically useful when the patient presents with a history of symptoms suggesting…
Sarcoidosis is a disease of unknown etiology which is characterized pathologically by widespread noncaseating granulomas involving multiple organ systems. We report a case of sarcoidosis presenting as a ventilation-perfusion mismatch on a lung scan.
Transport of protein across the alveolar epithelial barrier is a critical process in recovery from pulmonary edema and is also important in maintaining the alveolar milieu in the normal healthy lung. Various mechanisms have been proposed for clearing…
Intercostal artery laceration is an unusual complication following thoracentesis, and has been reported only in elderly patients. We report a case of a 78-year-old man who developed a massive hemothorax following thoracentesis. Post-thoracentesis…
