Lettori di Albertano : qualche spunto da un codice milanese del Trecento

Albertano da Brescia (1190 circa \u2013 1250 circa) viene considerato oggi dalla storiografia internazionale come una delle figure chiave del medioevo. Giudice, politico, letterato, predicatore, egli fu autore di una serie di opere, tre trattati didattico-morali e cinque sermoni confraternali, che conobbero una grande diffusione, sia nell\u2019originale latino sia tradotte in numerose lingue europee. A lui \ue8 stato attribuito il progetto pedagogico ed etico di costruzione del civis medievale, membro della societ\ue0 religiosa e dello stato. Attraverso un codice conservato presso la Biblioteca Trivulziana, posseduto a fine Trecento dai due fratelli entrambi cittadini di Milano, si cercher\ue0 di indagare la riuscita di questo progetto, approfondendo alcuni aspetti del bacino di ricezione e dei canali di trasmissione delle sue opere. In particolare si considereranno ambienti sociali e politici, persistenza del latino, fruizione femminile.Albertanus of Brescia (c. 1190s\u2013c.1250s) is nowadays considered by international historiography as one of the key figures of the Middle Ages. Judge, politician, writer, preacher, he was the author of three moral-didactic treatises and five confraternity sermons that enjoyed great diffusion, both in their original Latin and in subsequent translations in many european languages. He\u2019s been attributed the pedagogical and ethical project of building the medieval civis, member of the religious community and of the state as well. Through the lens of a codex of the Trivulziana Library, belonged in the late 14th century to two brothers citizen of Milan, we\u2019ll try to check the success of this project, deepening some aspetcts of the catchment area and of the transmission channels of his works. In particular, they will be taken into consideration social and political environments, latin\u2019s persistence, women\u2019s fruition

Gli utenti della strada : mercanti, pellegrini, militari

Con riferimenti specifici alla pianura padana, il saggio esamina in particolare il problema della sicurezza degli itinerari stradali nel tardo medioevo, che si pone in modo diverso per le diverse categorie di fruitori prese in esame (mercanti, pellegrini, militari)

Confraternite religiose laiche : repertorio

Il contributo fornisce una breve nota introduttiva sul problema delle confraternite medievali, e una descrizione selettiva delle risorse bibliografiche e informatiche relative sia all'Italia sia ad altri contesti internazionali

Role of endoscopy in lateral skull base approaches to the petrous apex

Objective: The aim of this article is to study the role and advantages of combined microscopic/endoscopic procedures or exclusive endoscopic approaches in the treatment of petrous apex pathologies. Methods: The study was designed as a retrospective case series analysis. We included patients affected by pathologies of the petrous apex, who underwent microscopic/endoscopic-assisted or exclusive endoscopic procedures. Patient and pathology characteristics and surgical data (focusing on the involvement of the internal carotid artery (ICA) and facial nerve by the disease) were collected. Residual disease, detected through the endoscopic check, and the feasibility of endoscopic residual tumor removal were also evaluated. Finally, facial nerve and hearing functions were assessed pre- and postoperatively. Results: The records of 75 patients undergoing lateral skull base surgery for petrous apex lesions, from May 2009 to March 2019, were collected. In 17 out of 75 patients, an exclusive endoscopic procedure was possible. The remaining 58 patients underwent a combined microscopic/endoscopic approach. In 15 cases, residual disease was found and removed endoscopically at the end of the microscopic procedure; in eight cases, the residual disease was medial and/or inferior to the horizontal segment of the ICA, while in two cases, it was located in the fundus of the internal auditory canal. In five cases, it involved the labyrinthine segment of the facial nerve. Conclusion: Petrous apex surgery remains a traditional microscopic-based surgery, but the recent advent of endoscopic surgery has permitted an improvement in radicality minimizing the manipulation of neurovascular structures

Complications in endoscopic ear surgery

Objective: The aim of this study was to examine the premise that endoscopic ear surgery (EES) is associated with a low rate of complications (intraoperative and postoperative). Study design: Retrospective review at two institutions. Setting: Tertiary referral center. Patients: The study included 825 patients who underwent exclusive EES between 2008 and 2016 at the Otorhinolaryngology-Head and Neck Surgery Department of Modena University Hospital, and between 2014 and 2016 at the Otorhinolaryngology-Head and Neck Surgery Department of Verona University Hospital. Interventions: Exclusive endoscopic ear surgery between 2008 and 2016 (tympanoplasties, second look or revision tympanoplasties, myringoplasties, stapedoplasties, canalplasties, ossiculoplasties, and exploratory tympanotomies). All surgical procedures were performed by two experienced surgeons. Main outcome measure: For each procedure, intraoperative, and early and delayed postoperative complications were evaluated. Results: The most common ear pathologies for which patients were sent for EES were cholesteatoma (33.6%), chronic otitis media (36.3%) and otosclerosis (26.8%). There was no case of major intraoperative complications such as injury to the dura or vascular structures. We observed minor intraoperative complications in 4.1% of the cases. Only 1.3% of patients experienced early postoperative complications. Delayed complications affected less than 1% of the cohort. Conclusions: Data from this study confirm the safety of the endoscopic technique, with very low complication rates, indicating that EES is a reliable therapeutic option, in particular, for tympanoplasties, myringoplasties, and stapedoplasties, as well as second look procedures. We have reported our experience with EES morbidity so that it can be compared with data from other centers using the same surgical technique

Results on entire solutions for a degenerate critical elliptic equation with anisotropic coefficients

In this paper, we study the following degenerate critical elliptic equations with anisotropic coefficients $$-div(|x_{N}|^{2\alpha}\nabla u)=K(x)|x_{N}|^{\alpha\cdot 2^{*}(s)-s}|u|^{2^{*}(s)-2}u {in} \mathbb{R}^{N}$$ where $x=(x_{1},...,x_{N})\in\mathbb{R}^{N},$ $N\geq 3,$ $\alpha>1/2,$ $0\leq s\leq 2$ and $2^{*}(s)=2(N-s)/(N-2).$ Some basic properties of the degenerate elliptic operator $-div(|x_{N}|^{2\alpha}\nabla u)$ are investigated and some regularity, symmetry and uniqueness results for entire solutions of this equation are obtained. We also get some variational identities for solutions of this equation. As a consequence, we obtain some nonexistence results for solutions of this equation.Comment: 29 page

Studi confraternali: orientamenti, problemi, testimonianze

Il volume raccoglie interventi di studiosi italiani e stranieri miranti a offrire una panoramica di percorsi storiografici e di problematiche relativi alla storia del movimento confraternale, così come sono emersi nell'ambito di discipline storiche, sociali, giuridiche, letterarie e artistiche sviluppatesi nel corso del Novecento. I contributi si riferiscono al contesto storico dell'Europa occidentale, con più specifico riguardo per l'Italia, nel periodo compreso fra medioevo e prima età moderna. La raccolta si articola in quattro sezioni: Individui e gruppi, che sonda l'emergere di un interesse verso le comunità confraternali all'interno di ambiti di studio come la storia dei gruppi sociali, del mondo rurale, delle donne, dei giovani; L'inquadramento giuridico e istituzionale, che affronta problemi di legittimità e di assetto istituzionale; L'economia della carità, che analizza il rapporto delle confraternite con gli enti ospedalieri, le modalità amministrative dei patrimoni confraternali, le culture di governo che sottostanno a politiche assistenziali di cui le confraternite sono tramite principale; Testimonianze teatrali, musicali, artistiche, documentarie dedicata alle fonti che le confraternite hanno saputo trasmettere
