2018

The study presents a report of 58 metastatic cancer patients who developed osteonecrosis of the jaws after being treated with zoledronic acid and taxanes, plus corticosteroids. A retrospective analysis of data registered in the archives of two Italian osteonecrosis of the jaws treatment centers, who are based at the University of Messina and at the University of Palermo, was performed in order to study, in these patients, demographic data and characteristics such as frequency of cancer location, lines of therapy, frequency of cancer drugs, presence/absence of oral trigger, number, location, and stage of jaw osteonecrosis. It was found that the majority of patients developed advanced stages …

Impedance of space-charge-limited currents in organic light-emitting diodes with double injection and strong recombination

2006

The impedance model for a one-carrier space-charge-limited (SCL) current has been applied to explain some experimental features of double carrier organic light-emitting diodes. We report the analytical model of impedance of bipolar drift transport in SCL regime in the limit of infinite recombination. In this limit the ac impedance function is identical to that of a single carrier device, with a transit time modified by the sum of mobilities for electrons and holes, μn+μp. The static capacitance C(ω→0) is a factor of ¾ lower than the geometric capacitance, as observed for single carrier devices, but it is shifted to higher frequencies. It follows that impedance measurements in the dual-carri…

Choledochocele imaged with magnetic resonance cholangiography.

2000

Choledochal cysts are rare developmental malformations of the biliary tree. Percutaneous and endoscopic ultrasound, as well as endoscopic retrograde cholangiopancreatography, are recommended diagnostic tools. Magnetic resonance cholangiography may also contribute to the workup and treatment plan of patients with choledochal cysts. We report a 25-yr-old white woman with episodic nausea and moderate epigastric dyscomfort. Magnetic resonance cholangiography showed a rather spherical, cyst-like, fluid-filled structure in continuity with the prepapillary segment of the common bile duct, thus making a choledochocele (type III choledochal cyst) likely. The patient was treated by endoscopic sphinct…

Efficacy of lumen-apposing metal stents or self-expandable metal stents for endoscopic ultrasound-guided choledochoduodenostomy: a systematic review …

2020

Abstract Background Endoscopic ultrasound (EUS)-guided biliary drainage is becoming an option for palliation of malignant biliary obstruction. Lumen-apposing metal stents (LAMS) are replacing self-expandable metal stents (SEMS). The aim of this meta-analysis was to evaluate the efficacy and safety of LAMS and SEMS for EUS-guided choledochoduodenostomy (EUS-CDS). Methods A meta-analysis was performed using PRISMA protocols. Electronic databases were searched for studies on EUS-CDS. The primary outcome was clinical success. Secondary outcomes were technical success, reintervention, and adverse events. We used the random effects model with the DerSimonian–Laird estimation, and the results were…

Double-balloon endoscopy for retrograde cholangiography in patients with choledochojejunostomy and Roux-en-Y reconstruction.

2009

BACKGROUND Choledochojejunal anastomoses with Roux-en-Y reconstruction excludes the biliary tract from conventional endoscopic retrograde cholangiography (ERC) with standard endoscopes due to the length of the interposed small bowel segment. Double-balloon enteroscopy (DBE) facilitates deep insertion into the small bowel and may be used to perform ERC in these patients. In the present case series we report our experience with diagnostic and therapeutic double-balloon ERC in patients with choledochojejunostomy to a long Roux-en-Y loop previously unavailable for standard length endoscopes. PATIENTS AND METHODS Between December 2004 and May 2008 15 patients (mean age: 60.2 years) with choledoc…

L'eroico, il meraviglioso e la scultura immaginifica lungo l'asse di via Toledo a Palermo (XVI-XVIII secolo)

2017

Lungo la via Toledo (oggi corso V. Emauele) e sul suo prolungamento extra moenia (stradone di Monreale, attuale corso Calatafimi) si snoda un itinerario immaginifico che si rivela nell'iconografia delle fontane, dei monumenti e degli apparati architettonico-scultorei nei quali temi eroici, cavallereschi e fantastici si intrecciano e si sovrappongono, veicolando valori ideologici , politici, civici . Sul percorso della rinnovata strada del Cassaro, il nuovo asse rappresentativo della città e luogo deputato a "teatro"di ogni manifestazione civile e religiosa, si dispiega il "meraviglioso" che si incontrava nei libri di cavalleria, e la fantasia, i miti, le leggende risvegliati dai romanzi amo…
