Ex nihilo. Ex nihilo is a Latin phrase meaning out of nothing. It often appears in conjunction with the concept of creation, as in creatio ex nihilo, meaning creation out of nothing, chiefly in philosophical or theological contexts, but it also occurs in other fields.
Diaphragmatic hernia is a defect or hole in the diaphragm that allows the abdominal contents to move into the chest cavity. Treatment is usually surgical. The following types of diaphragmatic hernia exist: 1  Congenital diaphragmatic hernia. 2  Morgagni's hernia. 3  Bochdalek hernia. 4  Hiatal hernia.
A diaphragmatic hernia that occurs through this opening is called a hiatus hernia. The cause of hiatus hernia is usually unknown, but it may be caused by stretching of the bands of tissue that are attached between the esophagus and diaphragm at the hiatus. The condition is more common among people who are older than 50, who are overweight (particularly women), or who smoke.
