Le antichità di Adria da collezione di famiglia a Museo Nazionale
No full textNell’ambito delle celebrazioni per il 200anniversario della morte di Francesco Girolamo Bocchi, illustre rappresentante della famiglia di Adria che diede il via in città alla ricerca archeologica, si ricostruisce la storia che ha condotto la collezione Bocchi, denominata dal possessore ‘domestico museo’, a diventare prima il Museo Civico e quindi il Museo Archeologico Nazionale, inaugurato nel 1961. La storia critica delle ricerche si intreccia con quella delle prime soluzioni di conservazione del patrimonio archeologico adriese, in particolare dell’ingente collezione di ceramica greca e di reperti etruschi

No full textRedo Gracilis Muscle Transposition for Recurrent Complex Pouch-Vaginal Fistula: A Feasible and Effective Pouch Salvage Surgical Procedure.
No full textBACKGROUND. Pouch-vaginal fistulae (PVF) affect 4 to 16% of women after ileal-pouch-anal anastomosis (IPAA) and significantly impact the patients’quality of life. They indeed represent a challenge for the surgeon. A variety of surgical options have been described but the reported pouch failure rate varies between 20 and 30% after the development of a PVF. Gracilis muscle transposition (GMT) is often considered a last resort treatment after the failure of multiple previous attempts.
CASE REPORT. A 45 years old women came to our tertiary IBD surgical department due to a recurrent PVF. She had already been treated elsewhere with multiple surgical repairs (mucosal advancement flaps, local injection of Adalimumab and redo-pouch). She had a severe pelvic sepsis and an IPAA stricture. Therefore, a pelvic surgical toilette, a diverting loop ileostomy and the dilatation of the anastomotic stricture were performed. After twelve months, a left GMT was fashioned. Unfortunately, three months after the procedure, a pouchoscopy and a contrast enema revealed an early recurrence of the fistula. After further six months, the patient was scheduled for a redo GMT as a rescue procedure of a pouch salvage strategy. After the transversal incision through the perineal body the pouch-vaginal fistulous track was identified and repaired. The left gracilis muscle was still in place, viable and well-vascularized. The right gracilis mucle was transposed to the perineum and secured to the apex of the dissection in the cavity between vagina and pouch, lying along the left muscle previously placed. After three months healing, of the PVF was assessed and confirmed with pouchoscopy. So, the patient was scheduled for closure of the ileostomy. Twelve months after reversal of fecal diversion, the successful healing is maintained.
DISCUSSION. GMT is usually advocated as a last resort strategy for PVF before declaring a pouch failure. However, redo gracilis GMT is a faesible and effective pouch salvage procedure in a tertiary IBD surgical center
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Antibiotic Prophylaxis for Surgical Site Infection in General Surgery: Oncological Treatments and HIPEC
No full textThe procedure of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is a combined surgical and oncological treatment for peritoneal carcinomatosis of various origins. Antibiotic prophylaxis is usually center-related and should be discussed together with the infectious disease specialist, taking into account the advanced oncologic condition of the pa-tient, the complexity of surgery—often requiring multiorgan resections—and the risk of post-HIPEC neutropenia. The incidence of surgical site infection (SSI) after CRS and HIPEC ranges between 11 and 46%. These patients are also at high risk of postoperative abdominal infections and septic complications, and a bacterial translocation during HIPEC has been hypothesized. Many authors have proposed aggressive screening protocols and a high intra and postoperative alert, in order to minimize and promptly identify all possible infectious complications following CRS and HIPEC
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
