Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [ 1 ] [ 2 ] [ 3 ] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung.
Laboratory testing for antibody to CMV can be performed to determine if a woman has already had CMV infection. Recovery of CMV from the cervix or urine of women at or before the time of delivery does not warrant a cesarean section. The demonstrated benefits of breast-feeding outweigh the minimal risk of acquiring CMV from the breast-feeding mother.
CMV infection or reactivation in people whose immune systems are compromised—for example people who have received transplants or are significantly burned—causes illness and increases the risk of death. [37] [38] CMV reactivation is commonly seen in people with severe colitis. [39] Specific disease entities recognized in those people are
Diseases associated with HHV-5 include mononucleosis and pneumonia, [4] [5] and congenital CMV in infants can lead to deafness and ambulatory problems. [6] In the medical literature, most mentions of CMV without further specification refer implicitly to human CMV. Human CMV is the most studied of all cytomegaloviruses. [7]
Pneumonia fills the lung's alveoli with fluid, hindering oxygenation. The alveolus on the left is normal, whereas the one on the right is full of fluid from pneumonia. Pneumonia frequently starts as an upper respiratory tract infection that moves into the lower respiratory tract. [55] It is a type of pneumonitis (lung inflammation). [56]
While pneumonia is a localized infection, pneumonitis is widespread. [3] A spirometer may also be used to measure pulmonary function. During external examination, clubbing (swelling of fingertip tissue and increase in angle at the nail bed), [14] and basal crackles may be observed.
Walking pneumonia infections rose nationwide as kids returned to school this fall. The infection can be tricky to diagnose, and testing is expensive. Doctors may choose different antibiotics to ...
Pneumonia is an infection that causes inflammation in one or both of the lungs. The pulmonary alveoli fill with fluid or pus making it difficult to breathe. [1] Pneumonia can be caused by bacteria, viruses, fungi or parasites. [1] Viruses are the most common cause of pneumonia in children, while in adults bacteria are a more common cause. [2]
