    Notes: Abstract We report three patients with bacterial intracranial aneurysms treated by the endovascular approach: two presented with sudden severe neurological deficits after a diagnosis of endocarditis; the other had suspected vasculitis. CT showed an intracerebral haematoma in all cases; angiography revealed bacterial aneurysms of distal branches of the middle cerebral artery in two cases and posterior cerebral artery in one. Because of the patients' condition and the location of the aneurysms, endovascular treatment was considered the fastest and safest treatment. Hyperselective catheterisation of the parent branch, close to the aneurysm, was performed with a microcatheter. A small amount of glue was injected to occlude both the aneurysm and a short segment of the diseased vessel. Follow-up angiography revealed occlusion of the aneurysm in all cases. One patient recovered completely; one recovered over some months, with neurological deficit due to the haematoma. The third patient suddenly worsened and died 9 days after treatment for a contralateral haematoma, due to rupture of a new bacterial aneurysm of the middle cerebral artery. Endovascular occlusion of the aneurysm and parent vessel may be an alternative to surgery in selected, severe cases of deep or distal bacterial intracranial aneurysms.

    Determination of heparan sulphate in kidney tissues of patients with calcium nephrolithiasis (1995)
    Springer
    Urological research 23 (1995), S. 339-342

    Notes: Abstract While the pathogenic mechanisms responsible for calcium nephrolithiasis remain unknown, the influence of heparan sulphate proteoglycan (HSPG) on disease progression of other diseases, such as polycystic kidneys and diabetic glomerulosclerosis, makes it an important candidate for the study of stone formation. Using the indirect immunofluorescence assay and image analysis, we were able to quantify and visualize the loss of HSPG localized in the basement membrane of the glomerulus and the mucosa of ureter or renal pelvis in patients with recurrent calcium nephrolithiasis as compared to normal subjects. However, no significant change in HSPG was observed in the basement membrane of the tubular epithelium. The decreased HSPG in the glomerulus may reflect the potentially disrupted anion/neutral barrier for glomerular filtration, which would encourage the accumulation of stone solutes. The drop in HSPG staining intensity in the basement membrane of the mucosa of ureter/renal pelvis may suggest the tendency of adhesion of crystal to urothelial surfaces. Based on these immunological data, it appears that HSPG plays a modulatory role in the pathogenesis of this disease.

    Notes: Abstract Previous studies have shown a significant decrease of heparin sulfate proteoglycan (HSPG) in the basement membrane of the glomerulus and the mucosa of the ureter/renal pelvis in patients with calcium nephrolithiasis. In this study, we looked at the localization of another influential proteoglycan, chondroitin sulfate (CSPG), using similar study groups by indirect immunofluorescence staining. Microscopic images were digitized and image analysis was used to quantitate the staining intensity of CSPG present in the basement membrane of the nephron. Our data showed significant loss of CSPG in the Bowman's capsule and the basement membrane of the mucosa of the ureter/renal pelvis using Mann-Whitney U-Wilcoxon Rank Sum W test with P-values of 0.0043 and 0.0041, respectively. However, absence of staining was noted in the basement membrane of the glomerulus and no significant change in the basement membrane of the tubular epithelium was observed. In conclusion, our results showed changes in the localization of CSPG in the basement membrane of the nephron, accompanied with HSPG, which may contribute to the pathological condition of calcium nephrolithiasis.
