[One-stage operation in 4 intracranial aneurysms]. / Jednoetapowa operacja czterech tetniaków wewnatrzczaszkowych.

The authors report a patient aged 58 years with a history of two episodes of subarachnoid haemorrhage and with arteriographic finding of four intracranial aneurysms: two on the internal carotid artery, one on the trifurcation of the middle cerebral artery, and one on the anterior communicating artery. Despite rather poor general and local condition (III clinical group) during the operation all four aneurysms were closed with clips. After a stormy postoperative course the condition of he patient improved and 6 months later he was feeling well, had no paresis, and only some memory disturbances remained. This case shows that multiple intracranial aneurysms should be treated in one-step operation, if this can be done from one surgical approach. This is important particularly in these cases in which it is difficult to say which aneurysm is bleeding.

[Diagnosis of cysticercosis using the intradermal test]. / Diagnostik der Zystizerkose mit Hilfe des Intradermaltestes.

56 healthy rabbits were inoculated with the active Cysticercus each into lateral ventricle of the brain, the white substance of the brain and into Spatium subarachnoideale. Rabbits were killed after 32 weeks p.i. Then their brains were macro- ev. microscopically investigated. The positive seroreactions (ringpreciptitation reaction and the latex-test) were observed at the beginning of the second week after infection. Curve of the titers was revealed two tops: first one between 6-7 weeks, second one 16-22 weeks after infection. All rabbits except one reacted positive on the application of the Cysticercus antigen. The control group consisted of the 8 rabbits revealed negative serological and immunological reactions. Three groups of the cerebral cysticercosis, dependent on the localization of the cysticerci in the brains, were observed: oedema form, hydrocephalous form and tumor form. These forms as well as the symptoms are similar to the human cerebral cysticercosis.
