Negative-pressure pulmonary edema (NPPE), also known as Postobstructive Pulmonary Edema, is a clinical phenomenon that results from the generation of large negative pressures in the airways during attempted inspiration against some form of obstruction of the upper airways.
As pulmonary edema has a wide variety of causes and presentations, the outcome or prognosis is often disease-dependent and more accurately described in relation to the associated syndrome. It is a major health problem, with one large review stating an incidence of 7.6% with an associated in hospital mortality rate of 11.9%. [ 2 ]
Regressive autism occurs when a child appears to develop typically but then starts to lose speech and social skills and is subsequently diagnosed with ASD. [15] Other terms used to describe regression in children with autism are autism with regression , autistic regression , setback-type autism , and acquired autistic syndrome .
The outcome of treatment is dependent on causality. Pulmonary Hemorrhage is present in 7 to 10% of neonatal autopsies, but up to 80% of autopsies of very preterm infants. [1] The incidence is 1 in 1,000 live births. [1] Pulmonary hemorrhage has a high mortality rate of 30% to 40%. [1]
High-altitude pulmonary edema (HAPE) is a life-threatening form of non-cardiogenic pulmonary edema that occurs in otherwise healthy people at altitudes typically above 2,500 meters (8,200 ft). [2] HAPE is a severe presentation of altitude sickness. Cases have also been reported between 1,500–2,500 metres or 4,900–8,200 feet in people who ...
Pulmonary surfactant is a complex system of lipids, proteins and glycoproteins that is produced in specialized lung cells called Type II cells or Type II pneumocytes. The surfactant is packaged by the cell in structures called lamellar bodies, and extruded into the air spaces. The lamellar bodies then unfold into a complex lining of the air space.
Long-term outcome is usually excellent for most patients, however residual post-surgical defects such as pulmonary regurgitation, pulmonary artery stenosis, residual VSD, right ventricular dysfunction, right ventricular outflow tract obstruction may affect life expectancy and increase the need for reoperation.
This described nine children who in addition to congenital heart disease had characteristic facial features, chest deformities and short stature. Dr. John Opitz, a former student of Noonan's, first began to call the condition "Noonan syndrome" when he saw children who looked like those whom Dr. Noonan had described.
