    Scanning electron microscopy (S.E.M.) of biopsy specimens of ruptured intracranial saccular aneurysms (1978)
    Springer
    Acta neuropathologica 44 (1978), S. 131-134

    ISSN: 1432-0533

    Topics: Medicine
    Notes: Summary Surgical specimens of 4 intracranial saccular aneurysms were studied by scanning electron microscopy. The internal surface of the aneurysms showed crater-like defects and cytoplasmic bridges. In some areas the endothelium was preserved, but its longitudinal convolutions were higher and thicker than those found in unchanged areas. On the damaged endothelial surface there was an increased number of blood cells. The adventitia resembled that of a normal cerebral artery. In conclusion the alterations observed are similar to those found in atherosclerosis and are most likely dut to the high wear and tear provoked by the blood streaming into the aneurysm. The results of this study are in agreement with the findings of a companion transmission electron microscopy study and emphasize the importance of degenerative changes on the development and rupture of intracranial saccular aneurysms.

    Fine structure of prolactin pituitary adenoma with special reference to annulate lamellae (1979)
    Springer
    Acta neuropathologica 46 (1979), S. 163-166 
    Details
    ISSN: 1432-0533
    Keywords: Electron microscopy ; Pituitary adenoma ; Annulate lamellae
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Electron microscopy revealed the presence of annulate lamellae in the cytoplasm of a heavily granulated prolactin cell adenoma that had been removed from a 34-year-old male patient presenting impotence. To our knowledge this is the third case of pituitary adenomas where annulate lamellae are reported.

    Histological and ultrastructural study of intracranial saccular aneurysmal wall (1978)
    Springer
    Acta neurochirurgica 43 (1978), S. 171-182 
    Details
    ISSN: 0942-0940
    Keywords: Aneurysms ; electron microscopy
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary The material studied consists of 10 cases of intracranial saccular aneurysms. Four came from autopsies, and in each of the other six aneurysmal wall was obtained at surgery after clipping of the aneurysm. The most significant findings from this pathological study are the almost complete disappearance of the internal elastic lamina at the level of the aneurysmal neck, sclerosis of the muscle coat, and in satellite vessels and vasa vasorum disruption of the internal elastic lamina and partial luminal occlusion. The importance of ischaemic changes in the aneurysmal wall is discussed. Rupture of the aneurysm at the distal extremity of the sac depends probably on the progressive brittleness of its wall which becomes sclerotic and less resistant to the blood pressure within. Splitting or rupture of the aneurysm appears to be dependent on degenerative ischaemic alterations in its wall.

    Primary brain stem haematomas. Diagnosis and treatment (1980)

    ISSN: 0942-0940
    Keywords: Primary brain stem haematoma ; computed tomography ; differential diagnosis ; conservative treatment
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Case histories are reported of 18 patients in whom the diagnosis of primary brain stem haematoma5 and brain stem haemorrhage13 was made by computed tomography (CT). The possibility of an early diagnosis of brain stem haematoma, and the differential diagnosis of brain stem haemorrhage by a combination of clinical and tomodensitometric criteria is emphasized. It is concluded that CT is a highly reliable method for the diagnosis, location, and management of brain stem haematoma.

    Treatment of benign intracranial hypertension (1980)

    ISSN: 0942-0940
    Keywords: Benign intracranial hypertension ; ICP recording ; cerebral oedema ; arachnoid villi
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary This study is based on 11 cases with pseudotumour cerebri. In each case a high dose of Escin was administered intravenously, and the drug effect during ICP recording was observed. In seven cases the drug manifested a significant hypotensive effect. In these cases the treatment with Escin (20 mg every 8 hours) was continued for 3 days; the control if ICP after this period showed a normal pressure in all cases. Oral treatment was continued at the same dosage for 20–30 days and the patient was then discharged. All patients presented complete remission of the clinical syndrome and fundus normalization. Follow-up after a year showed no recurrence. In three cases the treatment with Escin was unsuccessful; these patients were given dexamethasone, with normalization of the syndrome. Another case that presented with a severe picture of intracranial hypertension and visual impairment was treated with Escin and dexamethasone without positive result. The patient improved with external CSF drainage, and was treated by a shunt procedure that induced remission of the syndrome.
