Asian cave-adapted diplurans, with the description of two new genera and four new species (Arthropoda, Hexapoda, Entognatha)
2021
Twenty-nine specimens of Diplura collected from eight caves in China and Myanmar contain two new genera, Hubeicampa Sendra & Lips gen. nov. and Mueggejapyx Sendra & Komerički gen. nov., as well as four new species, Anisuracampa ywangana Sendra & Komerički sp. nov., Hubeicampa melissa Sendra & Lips gen. et sp. nov., Pacificampa wudonghuii Sendra sp. nov. and Mueggejapyx brehieri Sendra & Komerički gen. et sp. nov. These cave-adapted taxa showcase an impressive diversity in morphological adaptation (troglomorphy) to cave ecosystems. Their sensorial equipment, setae and receptors in the cupuliform organ have unique forms (H. melissa gen. et sp. nov.), as well as the pretars…
Flow diversion for indirect carotid-cavernous fistula: Still an off-label indication?
2023
Background: Flow diversion (FD) is an established treatment for large or giant wide-necked unruptured intracranial aneurysms. In the past few years, the use of flow diverter devices was extended to several other “off-label” indications, including solitary or adjunctive treatment to coil embolization for direct (Barrow A type) carotid cavernous fistulas (CCFs). The use of liquid embolic agents still represents the first-line treatment for indirect CCFs. Typically, the ipsilateral inferior petrosal sinus or superior ophthalmic vein (SOV) is the preferred transvenous routes to access CCFs. In some cases, vessel tortuosity or different features make the endovascular access challenging, thus re…
Natural Course, Clinical Profile, and Treatment Strategies for Cerebral Cavernous Malformations
2022
A large body of evidence has suggested that the natural biology for symptomatic cerebral cavernous malformations (CCMs) is dynamic. These lesions exhibit a temporal clustering epiphenomenon and usually manifest with multispectral clinical patterns, the most relevant being hemorrhagic and seizurogenic events. Most patients with cerebral cavernous malformations are asymptomatic, and the lesions are detected as incidentalomas. However, association with the CCM3 gene, Zabramski type I and II lesions, and brainstem location have the propensity to increase the bleeding events. The rebleeding risk is 20%/year per lesion, which supports the need for surgical strategies for brainstem cavernous malfo…

"Per via di levare". Scavare e sottrarre in architettura
2014
Scavare, dal latino excavare (ex-cavare), possiede etimologicamente il significato di “rendere cavo” mediante l’azione del subtrahĕre (sottrarre). Tuttavia il significato del termine all’interno della sua necessaria disambiguazione non può essere inteso limitatamente alla luce dell’etimologia latina. Si dirà allora che la tecnica dello scavo è opposta e complementare alla tecnica dell’accumulazione. È un procedere per sottrazione di volumi, un operare in negativo per asportazione di materiale, erodendo, cavando ed estraendo. Il saggio indaga, attraverso un intenso per quanto lacunoso excursus tra le esperienze della contemporaneità l'emergere del archetipico della dimensione ipogea dell’arc…
The So-called “Mithraic Cave” of Angera
2018
Summary The existence of a mithraeum at Angera (VA, Italy) was assumed for the first time in the 19th century, after the discovery of two Mithraic inscriptions re-used as ornaments of a private garden in the middle of the small town. The location of the alleged mithraeum is still uncertain: the inscriptions have been found out of context, and the place of worship has never been localized. The “Antro mitraico” (Mithraic Cave), also known as “Tana del Lupo”, is a natural cave situated at the base of the East wall of the cliff on which the Rocca Borromeo (the Castle of Angera) stands. At the cave the most visible archaeological evidences are tens of breaches cut into the outside rocky wall, wh…
Impact of biocide treatments on the bacterial communities of the Lascaux Cave.
2009
The Lascaux Cave contains a remarkable set of paintings from the Upper Palaeolithic. Shortly after discovery in 1940, the cave was modified for public viewing and, in 2001, was invaded by a Fusarium solani species complex. Benzalkonium chloride was used from 2001 to 2004 to eliminate the fungal outbreak. In this study, we carried out a sampling in most of the cave halls and galleries. Sequence analysis and isolation methods detected that the most abundant genera of bacteria were Ralstonia and Pseudomonas. We suggest that, as a result of years of benzalkonium chloride treatments, the indigenous microbial community has been replaced by microbial populations selected by biocide application.

Spontaneous Meckel's cave hematoma: A rare cause of trigeminal neuralgia
2015
Background: The most common etiology of classic trigeminal neuralgia (TN) is vascular compression. However, other causes must be considered. Among these, spontaneous hematoma of the Meckel′s cave (MC) causing symptomatic TN is very rare. Case Description: We present the case of a 60-year-old woman with a 2-month history of left TN and diplopia. Neuroradiological examinations revealed a well-defined hematoma in the left MC. The patient underwent surgical decompression with a progressive neurological improvement. Conclusion: Despite the number of lesions potentially affecting the MC, spontaneous hemorrhage is rare but should be taken into account in the differential diagnosis.
