Re-ventriculostomy for treatment of obstructive hydrocephalus in cases of stoma dysfunction.
2002
In this article, 12 re-ventriculostomies in the treatment for obstructive hydrocephalus are described. The etiology of the hydrocephalus was a benign aqueductal stenosis in 9 patients, a tumor around the aqueduct in 2 patients and intraventricular bleeding in one patient. In all cases the initial ventriculostomy was successful, but after a time interval of 2 weeks to 6 years the patients developed similar clinical symptoms as preoperatively. In all except one case the radiological findings spoke in favour of stoma closure. Intraoperatively the stoma was completely closed in 9 patients and in 3 patients a subtotal closure was observed. In all cases a re-ventriculostomy was performed bluntly …
Endoscopic Third Ventriculostomy: Outcome Analysis of 100 Consecutive Procedures
1999
OBJECTIVE: Endoscopic third ventriculostomy (ETV) has been shown to be a sufficient alternative in the surgical treatment of occlusive hydrocephalus. To elucidate the ongoing discussion of timing, indication, and surgical technique, a retrospective analysis of 100 consecutive ETVs was conducted. METHODS: One hundred ETVs were performed in 95 patients (43 female and 52 male patients). Their age ranged from 3 weeks to 77 years (mean age, 36 yr). Hydrocephalus was caused by aqueductal stenosis in 40 patients, space-occupying lesions in 42, and intraventricular or subarachnoid hemorrhage in 8. One patient had postinflammatory hydrocephalus, and four patients had occlusive hydrocephalus of unkno…

Le malte idrauliche dell’Acquedotto Romano di Termini Imerese
2009
Aim of this paper is the characterization of ancient hydraulic mortars from the roman water supply system of Thermae (I-II cent. A.D.), known as “Aqua Cornelia” and "Figurella" aqueducts, more than 10 kilometers long. Because of malfunctioning of the "Barratina" siphon, major changes in the original adduction system were realized in several steps. Mortar samples were taken from both channels lining materials and structural elements, in order to contribute to answer some questions about the construction phases of the aqueduct. The materials characterization was performed by means of XRD analysis, optical microscopy, microRaman spectroscopy and simultaneous thermal analysis. The latter is a u…
Cernay-lès-Reims (Marne). Cernay-lès-Reims « le Bas de la Noue Saint Rémy » zone 9 [notice archéologique]
2019
Localisée en limite SE de l’agglomération rémoise, sur la commune de Cernay-les-Reims, l’emprise de l’opération porte sur une surface de 11 300 m2. Cette neuvième concentration de vestiges, fouillée sur un parc d’activité, correspond à un établissement rural de l’Antiquité tardive, prolongé à l’époque médiévale par une zone d’activité artisanale. Ces deux occupations se développent le long d’un axe de circulation qui perdure vraisemblablement de l’Antiquité à la première guerre mondiale.
Ponti in Sicilia fra Sette o Ottocento. Il modello dell'acquedotto romano
2015
Nella seconda metà del XIX secolo in Sicilia furono costruiti diversi ponti. Essi riprendevano ancora il modello degli antichi acquedotti romani, modello rilanciato nell'isola, negli anni Settanta del XVIII secolo, da Ignazio Paternò Castello, V principe di Biscari, che costruì un grandioso ponte acquedotto nel feudo di Aragona, presso Catania. Fin dal tado Settecento e nel corso del XIX infatti questo modello fu riattualizzato e si diffuse in tutta Europa attraverso numerosi trattati specialistici, portando alla realizzazione di strutture similari, con diversi ordini di arcate a tutto sesto. In the second half of 19th century some bridges were built in Sicily. They still raised the model o…
