Negative-pressure pulmonary edema accompanied by hemorrhage as a manifestation of upper airway obstruction is an uncommon problem that is potentially life-threatening. The principal pathophysiological mechanism involved is the generation of markedly negative intrathoracic pressure, which leads to an increase in pulmonary vascular volume and pulmonary capillary transmural pressure, creating a ri...

Goodpasture’s Syndrome (GS) is characterized by the classic triad of diffuse pulmonary hemorrhage, glomerulonephritis, and circulating anti-basement membrane antibodies1. It is an uncommon disorder, with an incidence estimated to be 0.3 cases per 100,000 people per year2. There is a male predominance, with a male to female ratio between 2:1 and 9:13. The disease may present at any age, although...

Negative pressure pulmonary edema following tracheal extubation is an uncommon and life-threatening complication of patients undergoing endotracheal intubation and general anesthesia for surgical procedures. The common pattern in these cases is the occurrence of an episode of airway obstruction upon emergence from general anesthesia, usually caused by laryngospasm. Patients who are predisposed ...

Neurogenic pulmonary edema caused by severe brainstem encephalitis is the leading cause of death in young children infected by Enterovirus 71 (EV71). However, no pulmonary lesions have been found in EV71-infected transgenic or non-transgenic mouse models. Development of a suitable animal model is important for studying EV71 pathogenesis and assessing effect of therapeutic approaches. We had fou...

Diffuse hemorrhage is a known but infrequent complication of amiodarone pulmonary toxicity and a cause of hemoptysis, with 12 cases reported up to now. Unlike other form of amiodarone pulmonary toxicity, early or very early1 onset seems to be common. It is thought to be mistaken for acute heart failure in many patients, due to similar clinical pattern and concomitant use of anti-aggregants or a...

BACKGROUND Strongyloidiasis is a chronic parasitic infection caused by Strongyloides stercoralis. Severe cases such as, hyperinfection syndrome (HS) and disseminated strongyloidiasis (DS), can involve pulmonary manifestations. These manifestations frequently aid the diagnosis of strongyloidiasis. Here, we present the pulmonary manifestations and radiological findings of severe strongyloidiasis....

McGraw-Hill Concise Dictionary of Modern Medicine [1] defines pulmonary-renal syndrome (PRS) as an idiopathic condition characterized by pulmonary hemorrhage, rapid progressive glomerulonephritis, and positive autoantibodies. Pulmonary-renal syndrome may be also defined as a heterogeneous group of multisystem diseases – e.g. Goodpasture syndrome, Wegener's granulomatosis, collagen vascular dise...
