Pulmonary Hemorrhage Syndrome as a Manifestation of ...
pulmonary hemorrhage syndrome has features in common with other respira-tory distress syndromes such as hyaline membrane disease (HMO), pulmonary hypoperfusion, and shock lung. Duringa prospective study of disseminated intra-vascular coagulation (DIC), a syndrome with pulmonary hemorrhage was repeatedly observed.

Pulmonary haemosiderosis is as an abnormal accumulation of haemosiderin in the lungs resulting usually from a diffuse alveolar haemorrhage. It may be primary (idiopathic) or secondary to a host of diseases [3]. Quantification of pulmonary hemorrhage is very difficult and often inaccurate in children. Though there is no consensus

Diffuse alveolar hemorrhage (DAH) (defined by the presence of hemoptysis, diffuse alveolar infiltrates, and a drop in hematocrit level) is one of the manifestations of primary pulmonary vas-culitis, among other entities (idiopathic alveolar hemorrhage, collagen vascular diseases, drug reactions, anticoagulation disorders).

Comment: Hemorrhage (Figure 1, Figure 2, Figure 3, and Figure 4) is characterized by accumulations of extravasated blood cells in airways, around pulmonary vessels, and/or in alveolar lumina. Hemorrhage may occur in the lung when there is extensive parenchymal or endothelial cell damage caused by pulmonary toxins.

classified as idiopathic pulmonary hemosiderosis (IPH) and account for less than 5% of all cases of pulmonary hemorrhage during infancy. The pathologic mechanism for IPH in children is unknown. Recent histo-morphologic techniques suggest that the initial histopathologic damage occurs at the alveolar epithelial surface (1 ).

Diffuse alveolar hemorrhage is an uncom-mon condition in which blood floods the alveoli, usually at multiple sites. It is also known as intrapulmonary hemorrhage, diffuse pulmonary hemorrhage, pulmonary alveolar hemorrhage, pulmonary capillary hemorrhage, alveolar bleeding, or microvascular pulmonary hemorrhage. In this article we review the ...

the alveolar basement membrane, or direct alveolar injury. Commonly three patterns of DAH are seen: pulmonary capillaritis, bland hemorrhage, and diffuse alveolar damage. 1. Pulmonary capillaritis is the most common pattern.4 It is characterized by neutrophilic infiltration into the alveolar septae, endothelial edema, injury, and fibrinoid ...

Pulmonary hemorrhage is a relatively uncommon event in the NICU. It generally is an ominous sign of severe illness. Premature infants are at greatest risk of hemorrhage. Poor outcomes are associated with pulmonary hemorrhage, so prompt recognition and treatment are critical. NICU, neonatal, hemorrhage, pulmonary hemorrhage, respiratory distress

The three histologic patterns accounting for the major-ity of DAH are pulmonary capillaritis, bland pulmonary hemorrhage, and diffuse alveolar damage.

Diffuse Alveolar Hemorrhage in Acute Myeloid Leukemia
Summary: Diffuse alveolar hemorrhage is a potentially fatal pulmonary disease syndrome that affects individuals with hematological and nonhematological malignancies. The range of inciting factors is wide for this syndrome and includes thrombocytopenia, underlying infection, coagulopathy, and the frequent use of anticoagulants,

Although postnatal alveolar and vascular development were not dis-rupted by VEGF expression, VEGF transgenic mice developed pul-monary hemorrhage, alveolar remodeling, and macrophage accumu-lation as early as 2 wk of age. Electron microscopy demonstrated abnormal alveolar capillary endothelium in the VEGF transgenic mice.
