Can Trauma Condition Vulnerable Individuals to Develop Catatonic Symptoms?

Limited research has been done on the risk and predisposing factors of catatonic symptoms induced by traumatic events. There seem to be two types or constructs of conditioning that predispose an individual to catatonic symptoms in response to traumatic events: external conditioning and internal conditioning. Here, we review a study that found a significant correlation between the Bush-Francis Catatonia Scale and the Adverse Childhood Experience questionnaire; we also review studies of rats that were conditioned to expect an electric shock who developed catatonia-like immobility without the shock being applied.

Application of smooth Teflon clip to inferior vena cava during radical cystectomy to prevent postoperative pulmonary embolism.

Between 1976-1986, a smooth Teflon clip was applied to the inferior vena cava of 56 patients who underwent radical cystectomy for bladder cancer. The purpose of the clip is to narrow the lumen of the inferior vena cava so that large emboli will be trapped and thus prevented from reaching the lungs. These 56 patients were compared with a group of 26 historical controls who underwent radical cystectomy without application of such a clip between 1967-1976.

Ulcer of the trigone: a late complication of cervical cerclage.

Since the introduction of cervical cerclage for management of the incompetent cervix, few late complications of the procedure have been reported. We report a late complication of cervical cerclage manifested as a trigonal ulcer. Trigonal erosion by the knot of a mersilene ligature that had been placed around the cervix 22 years previously caused the ulcer.
