A modified technique of ureteroplasty for megaureter in children
No full textPurpose: Excisional ureteroplasty carries the risks of jeopardizing the ureteral vasculature and leakage from the suture. The folding techniques are theoretically less prone to these risks, although they have other disadvantages due to the bulky ureter. According to the literature, these 2 approaches have similar complication rates of 4% to 25%, to include stenosis, reflux and leakage. We introduce a modified ureteroplasty technique with the aim of ensuring effective reduction of the ureteral diameter with minor risks to the vasculature. Materials and Methods: A total of 42 consecutive patients underwent ureteroplasty and reimplantation (Cohen 16, Politano-Leadbetter 3, psoas hitch 23) between 1994 and 2004, and were followed for 1 to 9 years. The ureter was opened longitudinally on its less vascularized area. Two parallel longitudinal incisions were made from the luminal side up to the musculature layer, leaving the adventitia untouched. The mucosal aspects lateral to these lines were discarded. The inner layer was closed with a running suture. The adventitial layer was closed with single stitches. Results: No leakage, stenosis or reflux was observed. In 3 ureters persistent dilatation was observed, without obstruction or reflux. Conclusions: Our modification combines some principles of the 2 classic techniques, with the purpose of decreasing the risks and disadvantages of both. We believe that our approach affords better preservation of the ureteral vasculature because the adventitia is preserved untouched, as well as effective caliber reduction so that the bulking problem is avoided. In addition, the technique is associated with a minor risk of leakage. Our results show that this approach is a valid option for megaureter correction in children.

La voce di Dante in Ariosto: qualche nota testuale e quantitativa
No full textIl saggio si sofferma sui principali lavori critici pubblicati dagli anni Sessanta del Novecento fino a oggi riguardo alle connessioni intertestuali tra le opere di Ariosto (e in particolare il Furioso) e la Commedia dantesca. L’attenzione dei critici si è dapprima soffermata sul riuso del lessico dantesco da parte di Ariosto (hapax, rime e serie di rime, fino a emistichi o a versi quasi interi in sequenza, perlopiù ricontestualizzati o sapientemente modificati). Maria Cristina Cabani ha definito parodico questo adattamento, giustificandolo con la necessità, da parte di Ariosto, di scegliere un registro narrativo distinto da quello di Dante. Per approfondire l’indagine sul rapporto intertestuale tra Furioso e Commedia è necessario cercare nuovi metodi: questo lavoro getta le basi per una ricognizione sulle microstrutture del testo, basata sui principi della linguistica testuale. Viene fornito un elenco dei versi inizianti per e e ma nel campione del I canto del Furioso: la struttura è infatti largamente usata da Dante (e da Ariosto) per scopi narrativi e prosodici. Segue un’analisi automatica tra il Furioso, la Liberata e due testi secenteschi, Il mondo nuovo di Stigliani e Il conquisto di Granata di Graziani. Tali statistiche mostrano che, contrariamente all’opinione comune, i narratori in versi del Seicento non sono meri imitatori di Tasso, ma tematicamente ritornano spesso alle parole chiave di Ariosto. E in filigrana compare anche Dante

A Simple technique for removing the nuss bar with one stabilizer: The lateral approach
No full textThe removal of the substernal bar after the Nuss operation is not always an easy and fast maneuver. Only a few different technical solutions have been described. In the original Nuss technique, the patient was lying on dorsal decubitus and rotated on the side during the procedure. The Noguchi technique avoids the rotation of the patient, but requires two incisions and straightening of the bar before pulling it out the thorax. Recently, another technique was proposed, avoiding the need of straightening the bar, but it is feasible only if two operative beds in a large operative room are available. We propose another approach for the removal of the bar: The patient is lying on the lateral decubitus, only one incision is performed, and the bar is pulled out along the thoracic wall. Twenty-one bars were removed by using the present approach without any complications. The advantages of our approach on the previous techniques are the single incision, no need of rotating the patient, straightening the bar, or having two operative beds. Our approach is not feasible when metallic stabilizers have been used on both sides, but in our experience, this was not necessary in order to stabilize the bar. © Mary Ann Liebert, Inc
