Erythrocyte rheology in acute cerebral thrombosis. Effects of ABO blood groups.

Within a few hours after a cerebral thrombosis in 220 patients, the flow-properties of the red blood cells (RBC) were analyzed by a filtration test that expresses quantitatively the deformability and aggregability of the RBC by the filtration indexes pT. Abnormal deformability of the RBC washed clean of plasma was found in 27.5% of the patients. Aggregability disorders, caused by the plasma trapped between the unwashed RBC, were found in 78.6% of the patients: computation of correlation coefficients between pT indexes and fibrinogen, which was found abnormally high in 88.2% of cases, demonstrated significantly that in the patients with A and B blood groups these aggregability disorders were due to fibrinogen and that they were caused by other components of plasma in patients with O and AB blood groups. All these disorders can account for blood hyperviscosity.

Two cases of choreatic syndrome caused by polycythemia vera.

Two patients with choreatic syndromes caused by polycythemia vera recovered after treatment of the polycythemia by only two venesections: this proves that the syndrome is due to reversible alterations. Investigations of the cerebral circulation in one of the patients showed that blood flow was lowest in the grey matter at the basal region of the brain: this suggests that the alterations might mainly occur there. However, investigation of erythrocyte rheology, glucose-6-phosphate dehydrogenase, serum concentrations of caeruloplasmin and serotonin, and urinary excretion of epinephrine, norepinephrine and vanillylmandelic acid gave normal results in both patients. There are therefore no indications as to the possible pathophysiology of these alterations. There are now 24 cases reported, including our 2 patients, which suggests that the association of these two diseases may not be so rare as supposed.

Intrasellar abscess.

A case of intrasellar abscess in a 31-year-old male, with pituitary insufficiency, visual field and acuity disturbances, is reported. In the pus extracted at surgery E. coli and Staphylococcus haemolyticus were identified. The patient died 20 days after the operation. Necropsy revealed the fibrous capsule of an abscess in the hypophyseal region and putriform tissue at the level of the hypothalamus, with three small tumours one of which proved to be a craniopharyngioma.
