Laparoendoscopic single-site surgery for the treatment of benign adnexal disease: a prospective trial.
2010
Background. To validate feasibility, efficacy, and safeness of laparoscopic treatment of benign adnexal diseases through a single transumbilical access (LESS) in a prospective series of patients. Methods. A prospective clinical trial including 30 women has been conducted at the Division of Gynecology of Catholic University of Sacred Hearth of Rome. Patients underwent different laparoscopic procedures by LESS utilizing a multiport trocar and conventional straight laparoscopic instrumentation. Intra and perioperative outcome has been reported. Results. Ten mono/bilateral adnexectomies and 20 cystectomies have been performed by LESS approach. Laparoscopic procedures were completed through a si…
Relationship of subjective helplessness and pain perception after electric skin stimuli
2000
Objective and subjective controllability of painful stimuli are important factors in pain perception. The present study investigated direct and indirect effects of uncontrollability on perceived pain intensity in humans. Forty-eight healthy male volunteers participated in a laboratory experiment using a reaction time paradigm to induce controllable or uncontrollable feedback conditions in two randomly selected groups. Under controllable conditions, unpleasant electric skin shocks were applied, only when the actual time exceeded an individual threshold; under uncontrollable conditions, skin shocks were applied randomly using a yoked control design. Subjective helplessness, perceived pain int…
Associated Liver Partition and Portal Vein Ligation for Staged Hepatectomy (ALPPS) Registry: What Have We Learned?
2020
In 2007, the first associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) procedure was performed in Regensburg, Germany. ALPPS is a variation of two-stage hepatectomy to induce rapid liver hypertrophy allowing the removal of large tumors otherwise considered irresectable due to a too small future liver remnant. In 2012, the international ALPPS registry was created, and it now contains more than 1,000 cases. During the past years, improved patient selection and refinements in operative techniques, in particular, less invasive approaches such as Partial ALPPS, Tourniquet ALPPS, Ablation-assisted ALPPS, Hybrid ALPPS or Laparoscopic or Robotic approaches, have resu…
Unusual recurrence of trigeminal neuralgia after microvascular decompression by muscle interposal.
2011
Summary Background Patients with trigeminal neuralgia (TN) and persistent or recurrent facial pain after microvascular decompression (MVD) typically undergo less invasive procedures in the hope of providing pain relief. However, re-operation should be considered in selected patients. Case Report A 48-year-old woman presented with recurrent trigeminal neuralgia (TN) 3 years following microvascular decompression (MVD). The patient underwent brain magnetic resonance angiography (MRA), which did not reveal neurovascular compression; therefore surgical re-exploration was carried out. During the operation, the fifth cranial nerve was seen without impingement from any blood vessels; however, a ver…

SPH method: numerical investigations and applications
2018
In this paper we discuss on the enhancements in accuracy and computational demanding in approx- imating a function and its derivatives via Smoothed Particle Hydrodynamics. The standard method is widely used nowadays in various physics and engineering applications [1],[2],[3]. However it suffers of low approximation accuracy at boundaries or when scattered data distributions are con- sidered. In this paper we discuss on some numerical behaviors of the method. Some variants of the process are analyzed and results on the accuracy and the computational demanding, dealing with different sets of data and bivariate functions, are proposed.
Progettare interventi didattici personalizzati: implicazioni per la formazione dei futuri insegnanti
2020
L’articolo riporta i risultati di un’indagine sul terzo anno di tirocinio nel corso di laurea magistrale (LM 85-bis) in Scienze della Formazione Primaria dell’Università degli Studi di Palermo nell’anno accademico 2019-2020. È stato chiesto ai 269 studenti, che avevano svolto nei mesi precedenti 50 ore di tirocinio in classe, di descrivere le loro progettazion didattiche seguendo una guida, appositamente costruita, che li aiutasse anche a svolgere una riflessione metacognitiva sulla didattica personalizzata; inoltre la capacità decisionale degli studenti, valutata con il test QTD, è stata messa in relazione con la loro capacità di progettare in una scuola inclusiva. Al fine di preparare il …

CNO and pep solar neutrino measurements and perspectives in Borexino
2015
International audience; The detection of neutrinos emitted in the CNO reactions in the Sun is one of the ambitious goals of Borexino Phase-II. A measurement of CNO neutrinos would be a milestone in astrophysics, and would allow to solve serious issues in current solar models. A precise measurement of the rate of neutrinos from the pep reaction would allow to investigate neutrino oscillations in the MSW transition region. The pep and CNO solar neutrino physics, the measurement in Borexino Phase-I and the perspectives for the new phase are reviewed in this proceeding.
Caratterizzazione geotecnica del comporportamentodi una grande frana in argille varicolori in Sicilia
2014
Si illustrano le misure degli spostamenti e delle pressioni neutre raccolte in un paio d’anni di osservazione del comportamento di un esteso corpo di frana in una formazione di argille varicolori in Sicilia. L’analisi delle misure raccolte indica che la riattivazione riguarda zone distinte del corpo di frana, nelle quali gli spostamenti si sviluppano con velocità e direzioni differenti. L’evoluzione degli spostamenti è manifestamente dipendente dalle condizioni climatiche, dal momento che essi aumentano al crescere delle pressioni interstiziali, a loro volta regolate dalle piogge, e rallentano nella stagione secca, spesso senza annullarsi del tutto. Analisi a ritroso effettuate in una delle…
