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.
Pneumonia, according to the Mayo Clinic, is an infection that inflames the air sacs in one or both lungs, causing cough with phlegm or pus, fever, chills, and difficulty breathing. The condition ...
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]
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
CMV colitis may be clinically manifested with diarrhea (usually non-bloody), abdominal pain, weight loss and anorexia. The diagnosis of CMV colitis is based on serology, CMV antigen testing and colonoscopy with biopsy. Clinical suspicion should be aroused in the setting of immunocompromised patient but it is much rarer in immunocompetent patient.
Continuous mandatory ventilation (CMV) is a mode of mechanical ventilation in which breaths are delivered based on set variables. Still used in the operating room, in previous nomenclature, CMV referred to "controlled mechanical ventilation" ("control mode ventilation"), a mode of ventilation characterized by a ventilator that makes no effort to sense patient breathing effort.
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]
