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 analysis can be used to determine if individuals have abnormal numbers of chromosomes or abnormal-sized chromosomes. 1  These abnormalities can be due to: 2  Nondisjunction: chromosomes did not separate in parental cells, leading to children that have too many or too few copies of chromosomes.
