Seltene Parotistumoren

2003

Tumors of the parotid gland can be benign or malignant lesions. The pathophysiology of rare tumors of the parotid gland is often not sufficiently explored. In this paper two rare histological entities are described.In one patient a benign sebaceous lymphadenoma was histologically diagnosed. This type of tumor accounts for only 0.1% of all adenomas. The international literature is not conclusive about whether the tumor originates in the parotid gland itself or in the parotid lymph nodes.The second patient presented with a metastasis from a glioblastoma in the parotid gland. Again, the mechanism for metastasis of an intracerebral tumor to the parotid gland remains unknown. Iatrogenic seeding …

Laparoscopic surgical management of localized recurrent ovarian cancer: a single-institution experience

2014

Background: Optimally, secondary cytoreduction is acknowledged as a valid option in terms of oncologic outcome for patients with platinum-sensitive recurrent ovarian cancer. In cases of localized relapse, a laparoscopic approach has been attempted at various institutions, but studies on its role for this subset of patients still are limited. This report describes the authors' experience using laparoscopic secondary cytoreduction for patients with localized recurrent ovarian cancer. The results from a retrospective analysis of a prospective case series are reported. Methods: Between October 2011 and May 2013, 29 patients with localized recurrent ovarian cancer were selected for a laparoscopi…

Probability Distribution of the Residence Times in Periodically Fluctuating Metastable Systems

1998

We investigate experimentally and numerically the probability distribution of the residence times in periodically fluctuating metastable systems. The experiments are performed in a physical metastable system which is the series of a biasing resistor with a tunnel diode in parallel to a capacitor. The numerical simulations are performed in an overdamped model system with a time-dependent potential. We investigate both the cases where the system is deterministically overall-stable and overall-unstable. In the overall-unstable regime, the experimental and the numerically investigated systems show noise enhanced stability in the presence of a finite amount of noise. The determined P(T) is mult…

Unsaturated sand in the stability of the cuesta of the Temple of Hera (Agrigento)

2013

In the Valle dei Templi in Agrigento seven Doric temples stand lengthwise the crest of a rigid calcarenite cuesta over a layer of carbonate sand which lies along a thick stratum of clays. The environment is highly prone to landslides since topplings of calcarenite blocks often occur. The rock slopes are moving back and the slope edge draw near to the foundation of the Temple of Hera Lacinia contributing to increase their perilous condition. To assess the role of unsaturated sands in the instability processes, after the compositional and textural analysis of the material, direct shear tests and oedometer tests have been carried out on sand samples initially at the natural state, with low or …

Metabolic impact of Partial Volume Correction of [18F]FDG PET-CT oncological studies on the assessment of tumor response to treatment

2014

AIM: The aim of this work is to evaluate the metabolic impact of Partial Volume Correction (PVC) on the measurement of the Standard Uptake Value (SUV) from [18F]FDG PET-CT oncological studies for treatment monitoring purpose. METHODS: Twenty-nine breast cancer patients with bone lesions (42 lesions in total) underwent [18F]FDG PET-CT studies after surgical resection of breast cancer primitives, and before (PET-I) and after (PET-II) chemotherapy and hormone treatment. PVC of bone lesion uptake was performed on the two [18F]FDG PET-CT studies, using a method based on Recovery Coefficients (RC) and on an automatic measurement of lesion metabolic volume. Body-weight average SUV was calculated f…

Appunti sui libretti per musica di Gioacchino Pizzi

2017

In recent years historians of the literature, culture and sociality of the academies have shown a renewed interest in Gioacchino Pizzi (Nivildo Amarinzio), who was the Custode of Arcadia from 1772 to 1790. On the other hand, there have been no specific studies of his relations with the world of music. The first part of the article offers a first inventory of Nivildo’s printed libretti, belonging to the genres of encomiastic cantata, sacred composition and dramma per musica. The second part illustrates the ideas on Italian and French theatre expounded by Pizzi in his "Ragionamento sulla tragica e comica poesia" (1772). It also reconstructs his relationship with Pietro Metastasio, and explore…

Sulla fortuna di «Misero pargoletto»: materiali e ipotesi

2020

The aria "Misero pargoletto", sung by Timante in the third act of Pietro Metastasio's "Demofoonte", enjoyed exceptional fortune throughout the eighteenth century. The text was set tu music dozens of times not only as part of the opera it belongs to, but also as an independent piece. This essay discusses the judgements expressed on "Misero pargoletto" by several men of letters and theorists, examines some buffo parodies of the aria that demonstrate its wide notoriety, and formulates some hypotheses about the reasons for such a great success, which can be partially justified by the new conception of fatherood that emerged in the so-called Age of Sensibility.

Calzabigi e Metastasio: Napoli, Parigi, Vienna e ritorno

2020

The relationship between Ranieri Calzabigi and Pietro Metastasio has been examined several times by historians of music and literature. According to some scholars, Calzabigi’s judgment on his older colleague remained consistent over time, while others have highlighted the profound difference between the ideas expressed in the "Dissertazione [...] su le poesie drammatiche del signor abate Pietro Metastasio" (1755) and those contained in the "Risposta di Santigliano" (1790). This essay retraces the stages of the complex bond between the two authors and, with the help of new observations as well as sources hitherto neglected, demonstrates that Calzabigi was influenced by Metastasio's verses in…
