Study objectives: Black smokers have been reported to have higher serum cotinine levels than do white smokers, and have higher rates of most smoking-related diseases, despite smoking fewer cigarettes per day. Another striking racial difference is the…
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.
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…
Decreases in circulating hsCRP have been associated with increased physical activity and exercise training, although the ability of exercise interventions to reduce hsCRP and which individuals benefit the most remains unclear. This meta-analysis…
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…
Objective: To test whether dopexamine hydrochloride, by its beta(2)-adrenoceptor and dopaminergic 1 (DA(1)) and dopaminergic 2 (DA(2)) agonistic properties, can improve oxygen consumption (V over dot O-2) in hyperdynamic patients with septic shock.…
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…
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…
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…
Objective: The purpose of this study was to determine if intravenous push metoclopramide would facilitate immediate transpyloric passage of a small-bore feeding tube without fluoroscopy or endoscopy. Design: Prospective, randomized trial. Patients:…
