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.
1 A karyotype cannot show if there are very small bits of chromosomes missing (deletions) or very small extra bits of chromosomes (duplications) 2  Small rearrangements of chromosomes cannot be detected.  The karyotype can not tell you information about the 30,000 genes that are found along the length of chromosomes.
