Geochemical and biogeochemical features of areas of haematuria in cattle in the Eastern Carpathian Mountains of Romania.

Haematuria-inducing areas in the northern and central parts of the Eastern Carpathian Mountains are characterised by the mesozoic-crystalline, neogene eruptive and transcarpathian flysch zones. The rocks have high concentrations of some metals and radioactive elements, some of them bearing polymetallic sulphides. The soils are strongly or moderately acid and oligomesobasic.

[Superacute extradural hematoma].

After a survey of data in the literature the authors have used four criteria for the identification of the supraacute extradural hematoma:--an interval of maximum two hours between the occurence of the trauma and the performance of the intervention or exitus;--a severe cerebral syndrome with primary brutal coma, or coma that has developed in the above-mentioned interval;--the discovery during intervention of a "developing" hematoma, mostly as fluid, and the identification of the source of haemorrhage;--persistent cerebro-ventricular collapse after evacuation of the hematoma, that makes necessary the application of operative procedures for achieving recovery. Two of the 5 observations of the authors are presented, both in males, aged 22 and 73 years respectively, in whom surgery was performed in an interval of less than two hours. All the patients were comatose when the intervention was carried out, and 3 of them had a temporal fracture.
