Aspiration pneumonia refers to pneumonia caused by accidental inhalation (aspiration) of food, drink, or vomit into the lungs. Swallowing difficulties, or conditions such as alcohol intoxication, confusion, or decreased mental alertness, may lead to aspiration pneumonia.
Karyotype is a test to identify and evaluate the size, shape, and number of chromosomes in a sample of body cells. Extra or missing chromosomes, or abnormal positions of chromosome pieces, can cause problems with a person's growth, development, and body functions.
A karyotype also can reveal deletions in chromosomes that are the underlying cause of conditions such as Cri-du-Chat syndrome (chromosome 5) or Williams syndrome (chromosome 7), as well as translocations in which one part of a chromosome is found on or switched with another part of a different chromosome.
