Fungal infections in transplantation patients
2003
Invasive fungal infections have became one of the principal obstacles to successful solid organ and bone marrow transplantation. The natural history and incidence of systemic fungal infection varies with the type of organ transplanted and the immunosuppressive therapy administered; the majority of infections occur within the first two months after transplantation. The most common fungi that cause disease in transplant recipients are Candida spp. and Aspergillus spp. The clinical presentations of fungal infections in solid-organ transplant recipients are non specific and often overlap with other infectious and non infectious processes; for this reason it's important maintain a high index of …

336 CONSECUTIVE DOPPLER GUIDED HEMORRHOIDAL ARTERY LIGATIONS (DGHAL)
2009
Objectives: Our purpose is to expose a new surgical technique for the treatment of II-III degrees haemorrhoids with pain-less and complication free post-operative period, with a considerable improvement of clinic story and with a very short time for return to work or to normal daily activity. Materials and Methods: From March 2004 to March 2009 we performed 336 consecutive DGHAL in patients (128 male and 208 female) with II (227 pts)-III (109 pts) grade hemorroidal disease in local anesthesia. The DGHAL procedure is performed with a special proctoscope (HAL Doppler , Pharma EECTM) that with an US probe can explore, above the dentate line, the arterial flux of median rectal artery. Across th…
Robotic transanal surgery: perspectives for application
2020
Transanal minimally invasive surgery (TAMIS) is a surgical technique which allows the local excision of rectal benign tumors and early stage cancers measuring up to 4 cm and lying within 6-8 cm from the anal verge. It is performed by means of a disposable transanal platform and conventional laparoscopic instruments, proving to be effective and easily available. Hence, TAMIS soon became a valid alternative to other transanal resective procedures, especially transanal endoscopic microsurgery, and rapidly spread. Moreover, soon after its introduction, TAMIS started to be performed also using robotic technologies, but no clear advantages were found to date. This review is intended to provide a …

Chirurgia trans-cranica mediante ultrasuoni focalizzati ad alta intensità su guida RM: esperienza preliminare a 1,5T
2015
Da qualche anno la chirurgia mediante ultrasuoni focalizzati ad alta intensità guidati da Risonanza Magnetica (Magnetic Resonance guided Focused Ultrasound Surgery, MRgFUS) si sta diffondendo anche in Italia per la palliazione del dolore da metastasi ossee, per il trattamento di tumori ossei primitivi (benigni e non), dei fibromi e dell’adenomiosi uterina; sono già stati inoltre pubblicati i risultati preliminari del trattamento di alcuni tumori epatici, pancreatici, prostatici e della mammella mediante MRgFUS. Questa innovativa tecnica prevede l’utilizzo di un’apparecchiatura di Risonanza Magnetica per il monitoraggio della procedura e sfrutta le caratteristiche fisico- meccaniche degli …
Navigation accuracy after automatic- and hybrid-surface registration in sinus and skull base surgery.
2016
Objective Computer-aided-surgery in ENT surgery is mainly used for sinus surgery but navigation accuracy still reaches its limits for skull base procedures. Knowledge of navigation accuracy in distinct anatomical regions is therefore mandatory. This study examined whether navigation accuracy can be improved in specific anatomical localizations by using hybrid registration technique. Study design Experimental phantom study. Setting Operating room. Subjects and methods The gold standard of screw registration was compared with automatic LED-mask-registration alone, and in combination with additional surface matching. 3D-printer-based skull models with individual fabricated silicone skin were u…
Is immunohistochemistry more sensitive than hematoxylin-eosin staining for identifying perineural or lymphovascular invasion in oral squamous cell ca…
2021
This study aimed to analyze whether immunohistochemistry (IHC) is more sensitive than hematoxylin-eosin (H&E) staining for identifying perineural invasion (PNI) or lymphovascular invasion (LVI) in oral squamous cell carcinoma (OSCC). In this systematic review and meta-analysis (Prospective Register of Systematic Reviews ? CRD 42021256515), data were obtained from six databases (PubMed, Scopus, LILACS, Web of Science, EBSCO, LIVIVO, Embase) and the grey literature. Cross-sectional observational studies of the diagnostic sensitivity of IHC for PNI and LVI were included. Studies were selected in two phases: first collection and reference retrieval. The Quality Assessment of Diagnostic Accuracy…
MRgFUS results Italy
2017
PURPOSE: To present our preliminary results achieved with the first Italian installation of a trans-cranial MRI-guided Focused Ultrasound Surgery (tcMRgFUS) certified system for functional neurosurgery. Moreover, to our knowledge, this is the world-first tcMRgFUS system ever installed on a 1.5T MRI unit. Technical issues faced to achieve a safe and effective treatment will be discussed focusing on MR high-resolution live imaging and thermometry sequences optimization. METHOD AND MATERIALS: Patient enrollment was based on indication for functional neurosurgery and evidence of medication-refractory disease; a detailed medical history has been collected together with a complete clinical examin…
Surface and volume non-invasive methods for the structural monitoring of the bass-relief ‘Madonna con Bambino’ (Gorizia, Northern Italy)
2016
Structural analysis of marble statues, carried out by non-invasive and in situ methods, is crucial to define the state of conservation of the artworks and to identify the deterioration phenomena that can affect them. In this work, we combined in situ non-destructive techniques, ultrasonic tomography (US), ultraviolet-induced visible fluorescence (UV-IF) and X-ray fluorescence (XRF) to study the bass-relief ‘Madonna con Bambino’ (Gorizia, Italy). The US revealed the presence of some metallic pivots, associated with areas of high sound velocity; moreover, a more degraded area has been identified in the lower part of the bass-relief. The acquired UV-IF image confirmed the presence of surface d…
