In children, hemoptysis is commonly caused by the presence of a foreign body in the airway. Other common causes include lung cancers and tuberculosis. Less common causes include aspergilloma, bronchiectasis, coccidioidomycosis, pulmonary embolism, pneumonic plague, and cystic fibrosis.
Infant prematurity is the factor most commonly associated with pulmonary hemorrhage. Other associated factors are those that predisposed to perinatal asphyxia or bleeding disorders, including toxemia of pregnancy, maternal cocaine use, erythroblastosis fetalis, breech delivery, hypothermia, infection (like pulmonary tuberculosis), Infant respiratory distress syndrome (IRDS), administration of ...
Hemoptysis may also indicate other, potentially fatal, medical conditions. [5] A history of exposure to potential causes and evaluation of symptoms may help in revealing the cause the exacerbation, which helps in choosing the best treatment. A sputum culture can specify which strain is causing a bacterial AECB. [5] An early morning sample is ...
This, in fact, is the ratio of re-hemoptysis mechanism occurring in 9.6% cases in 1 year, and in 14.1% of those in 2 years. [18] Recanalization was the main cause of re-hemoptysis, and the suppression of new hemoptysis-related vessels, which is the second cause, cannot be controlled by the BAE procedure itself.
Atypical bacteria causing pneumonia are Coxiella burnetii, Chlamydophila pneumoniae (), Mycoplasma pneumoniae (), and Legionella pneumophila.. The term "atypical" does not relate to how commonly these organisms cause pneumonia, how well it responds to common antibiotics or how typical the symptoms are; it refers instead to the fact that these organisms have atypical or absent cell wall ...
The etiology or pathophysiology of the disease remains unclear. However, in recent years, Hughes-Stovin syndrome has been found to be potentially caused by systemic venous angiitis or collagen disease. Systemic venous angiitis or vasculitis is an inflammatory disease of the blood vessels walls, secondary to autoimmune diseases.
A new study, which appears in Nature Medicine, has identified a biomarker that may eventually allow doctors to spot the early signs of protein buildup before it causes significant damage.
Viral causes include human respiratory syncytial virus (RSV), human metapneumovirus, adenovirus, human parainfluenza viruses, influenza and rhinovirus, and RSV is a common source of illness and hospitalization in infants. [8] CAP caused by fungi or parasites is not usually seen in otherwise-healthy infants.
