RESUMO
Seventy-seven anti-brucella and 42 anti-leptospira agglutinin serum levels of hares in Rio Cuarto district of Córdoba Province were studied. For brucella, only one sample showed incomplete reaction at a 1:25 dilution. The isolation of brucella from liver, spleen and gastro-hepatic lymph node in this animal was negative. In the 42 serum samples examined for L. pomona, L. wolffi, L. ballum, L. hardjo, L. pyrogenes and L. grippotiphosa, 6 reacted at a dilution of 1:100 with L. ballum serovar and 1 reacted up to 1:200 dilution with L. wolffi serovar. These results indicate that the hare does not play any important role as reservoir of pathogenic brucella in this area. Meanwhile, it could act as potential reservoir for pathogenic leptospira.

RESUMO
During the neurosurgical procedure in the sitting position a prospective study was performed with a Swan-Ganz catheter on 99 subjects. Gaseous embolism occured in 11 subjects (11%). The frequency increased twofold in the surgery of pontocerebellar angle tumors. Haemodynamic study of 10 gaseous embolisms showed a rise in pulmonary arterial pressure (15.3 +/- 5.2 to 32.4 +/- 32.4 +/- 7.7 mm Hg; p < 0.005) with a rise in pulmonary resistances (22 +/- 1.2 to 9.0 +/- 3.1 units; p < 0.005) and in right ventricular systolic work index (7.8 +/- 1.3 to 14.4 +/- 6.3 gm/m2; p < 0.02). The fall in mean arterial blood pressure was inconstant and moderate (89 +/- 19 to 78 +/- 23 mm Hg; p < 0.05) as was the fall in cardiac output (5.6 +/- 0.9 to 5.0 +/- 0.8 l/min; p < 0.01). Increasing FIO2 hid hypoxemia but, in five subjects, the intrapulmonary shunt rose from 7 to 31%. The therapeutic aspects are reviewed.

The authors report a case of post-traumatic intracranial hypertension with ICP paroxysmal rise related to subclinical epileptic seizures. The interest of detecting such a phenomenon is emphasized from a practical therapeutic point of view.
