The acute effect of systemic blood pressure reduction on intraocular pressure in hypertensive patients.

Objectives: Previous studies have shown an association between systemic hypertension and intraocular pressure (IOP). We analyzed the relationship between the decreases of the blood pressure (BP) and IOP in hypertensive patients.

Methods: The study includes a total of 214 patients: 158 hypertensive and 56 normotensive patients as study and control groups, respectively.

Tracheal rupture as a result of coughing.

Tracheal rupture is mostly traumatic or iatrogenic. A few cases of spontaneous tracheal rupture have been reported in literatüre and all of them have been described posterior membraneous wall which is the weakest portion of trachea. In most of such cases, predisposing factors that weaken the tracheal structure were present.
