Deep cerebral venous thrombosis and hereditary tissue plasminogen activator (t-PA) deficiency.

We describe a patient with defective tissue plasminogen activator (t-PA) release who developed internal cerebral vein thrombosis. She recovered completely and, as shown by MRI, favourable outcome was probably related to vascular recanalisation. Other members of the pedigree had a similar fibrinolytic deficiency without clinical manifestations.

Reversible cerebral ischemias: a comparative analysis of risk factors in TIAs and in RINDs.

A retrospective study in which 709 patients, 522 with RIND and 187 with TIA, were compared in respect of common risk factors (RFs) for acute cerebrovascular disease. The two forms of the disease differed significantly in respect of smoking, hematocrit, hypercholesteremia, hypertriglyceridemia and hyperuricacidemia. Although these RFs do not seem to be determinants of or discriminants between the two forms of acute cerebrovascular disease, it is nonetheless highly probable that, together with all the other RFs, they have a facilitatory role.

[EEG evaluation of patients undergoing extracorporeal circulation under analgesic and electrohypoalgesia with auricular acupuncture].

Electroencephalograms recorded 12 hours before and 12 hours after heart surgery in ECC and moderate hypothermia (30 degrees) are evaluated. Two groups of patients were studied: - the first group was composed of those undergoing analgesic anaesthesia; - the second group of those undergoing electroencephalograms by means of auricular acupuncture. In the first group the postoperative EEG was dominated by long "theta" and "delta" waves characteristic of the deep sedation of analgesic anaesthesia.
