Grandi maestri e tecniche di riproduzione. Lo spazio dell'oreficeria nell'arte a Lucca tra Quattro e Cinquecento
No full textIl saggio esamina il ruolo delle tecniche orafe all’interno della koinè artistica lucchese del tardo Quattrocento, registrando non solo il perfetto accordo stilistico tra arti maggiori ed arti suntuarie, ma anche la funzione di modelli svolta da queste ultime grazie al dominio dei mezzi di riproduzione meccanica rappresentati da nielli e placchett

No full textAmong 474 patients having 547 carotid endarterectomies (CEAs) over an 80-month period, 11 (2.3%) with symptomatic (n = 8) and asymptomatic (n = 3) severe (>70%) carotid stenosis had 12 asymptomatic intracranial aneurysms (IAs). None had postoperative stroke or died, and none
had surgical or endovascular IA treatment before or after CEA. In an average 5-year follow-up, no patients had subarachnoid hemorrhage. Having an IA does not seem to be an additional risk factor for CEA, nor does CEA seem to increase the chance of IA rupture
Neurosonographic monitoring of 105 spontaneous cervical artery dissections: a prospective study.
No full textAbstract
Objective To monitor the sonographic course of spontaneous cervical artery dissections (sCADs) and investigate their recanalization and recurrence rates.
Methods All consecutive patients with an MRI-proven sCAD were prospectively evaluated by neurovascular ultrasound (nUS) daily while in hospital, then monthly for the first six months after discharge and every six months thereafter, for a mean follow-up period of 58 months (range, 28-96 months).
Results One hundred and five sCADs were detected in 76 patients: 61 (58.1%) involved the internal carotid artery and 44 (41.9%) the vertebral artery, while multiple sCADs were found in four patients (5.3%). Follow-up was obtained in 74 patients (97.3%, 103 vessels). The complete and hemodynamically significant (<50% stenosis) recanalization rates were 51.4% (53/103) and 20.4% (21/103). All but one complete recanalizations occurred within the first nine months. There were early recurrences (while in hospital) in 20 previously-unaffected arteries (27%), and late recurrences in two arteries (2.7%) site of a previous sCAD. All patients (n = 6) with a family history of arterial dissection had a sCAD recurrence (four early and two late) as opposed to 16 (22.8%) among those with no known familial disease (p < .001).
Conclusions These results suggest that most lumen changes occur within the first few months after the initial event, but recanalization may occur even after one year. Early recurrence is not uncommon and usually involves arteries previously unaffected by dissection, while the risk of late recurrence is low. A family history of arterial dissection is strongly associated with sCAD recurrence
Transcranial Sonography in Neurodegenerative Diseases with Cognitive Decline.
No full textTranscranial sonography (TCS) of the brain parenchyma detects alterations in the substantia nigra (SN), raphe nuclei and basal ganglia; this technique has been established as a tool for the early diagnosis of Parkinson's disease and differential diagnosis from atypical parkinsonian syndromes. Here, we aimed to review the main applications of TCS in neurodegenerative diseases presenting with dementia syndrome, focusing on Alzheimer's disease (AD), dementia with Lewy bodies (DLB), frontotemporal lobar degeneration, idiopathic normal pressure hydrocephalus, and atypical and secondary parkinsonisms. The finding of bilaterally marked hyperechogenicity of the SN appears as a characteristic feature of DLB, while it is found only in a minority of AD patients. SN hyperechogenicity is also detected in most patients with corticobasal degeneration and in about one third of patients with progressive supranuclear palsy, in which is constantly associated with hyperechogenic alterations of the basal ganglia. In conclusion, TCS is a valid supportive tool in the diagnostic workup of patients with dementia due to different neurodegenerative conditions. A promising new application is the differentiation of DLB from AD even at the early stages of these diseases
