Common associated injuries include head injury, injuries to the aorta, fractures of the pelvis and long bones, and lacerations of the liver and spleen. Associated injuries occur in over three quarters of cases. History
In 1579, Ambroise Paré made the first description of diaphragmatic rupture in a French artillery captain who had been shot eight months before his death. He died from complications of the rupture. Using autopsies, Paré also described diaphragmatic rupture in people who had suffered blunt and penetrating trauma. Reports of diaphragmatic herniation due to injury date back at least as far as the 17th century. Petit was the first to establish the difference between acquired and congenital diaphragmatic hernia, which results from a congenital malformation of the diaphragm. In 1888, Naumann repaired a hernia of the stomach into the left chest that was caused by trauma. Other animals
Diaphragmatic rupture is a common and well-known complication of blunt abdominal trauma in cats and dogs. The organs that herniate into the pleural cavity are determined by the location of the rupture. They are most commonly circumferential tears that occur at the attachment of the diaphragm and rib. Is these cases, the organs that herniate may include the liver, small intestine, stomach, spleen, omentum, and/or uterus. Dorsal tears are uncommon, and may cause a kidney to herniate into the thorax. Symptoms include difficulty breathing, vomiting, collapse, and an absence of palpable organs in the abdomen. Symptoms can worsen quickly and be lethal, especially in the case of severe bleeding, bruised heart, or strangulation of herniated intestine.
Pigment dispersion syndrome (PDS) is an  eye disorder that can lead to a form of glaucoma known as pigmentary glaucoma. It takes place when pigment cells slough off from the back of the iris and float around in the aqueous humor. Over time, these pigment cells can accumulate in the anterior chamber in such a way that they begin to clog the trabecular meshwork (the major site of aqueous humour drainage), which can in turn prevent the aqueous humour from draining and therefore increases the pressure inside the eye. A common finding in PDS are central, vertical corneal endothelial pigment deposits, known as Krukenberg spindle. With PDS, the intraocular pressure tends to spike at times and then can return to normal. Exercise has been shown to contribute to spikes in pressure as well. When the pressure is great enough to cause damage to the optic nerve, this is called pigmentary glaucoma. As with all types of glaucoma, when damage happens to the optic nerve fibers, the vision loss that occurs is irreversible and painless. Risk factors
This condition is rare, but occurs most often in Caucasians, particularly men, and the age of onset is relatively low: mid 20s to 40s. As the crystalline lens hardens with age, the lens zonules pull away from the iris and the syndrome lessens and stops. The main risk factor is nearsightedness. Genetic factors may also play a part in the transition from syndrome to the glaucoma condition.
