Surgical treatment of early breast cancer in day surgery.

Quadrantectomy and associated sentinel lymph node biopsy (SLNB) is currently employed in most breast surgery centres as the gold standard in the treatment of early breast cancer. This approach has a modest morbidity and can usually be performed in a day-surgery regimen, leading to best acceptance by the patients. This reports outlines the experience of our Breast Unit with quadrantectomy and SLNB in day surgery for early breast cancer. One hundred patients presenting to our institution with primary invasive breast cancer measuring less than 3 cm and clinically negative axillary nodes underwent quadrantectomy and SLNB in day surgery. For 60 women with breast cancer the sentinel node was nega…

Valutazione delle possibilità e dei limiti del trattamento palliativo del carcinoma del retto mediante laser Nd-Yag versus colostomia

Tiroidectomia con LigaSure TM vs tiroidectomia tradizionale. Nostra esperienza

Nelle ultime decadi la strategia chirurgica delle affezioni tiroidee, sia benigne sia maligne, ha subito dìversi cambiamenti. ln par-ticolare, la tiroidectomia totale è og- gi divenuto l'intervento chirurgico di routine delìa maggior parte delle patologie ti- roìdee. Le complicanze di tale procedura chirurgica, sebbene a eziopatogenesi multifattoriale, sono spesso collegate all'efficacia dell'emostasi. ln questo lavoro, abbiamo voluto verificare se l'impiego del nuovo sistema emostatico LigaSurerM potesse ridurre l'incidenza di tali complicanze, nonché i tempi operatori e i giorni di degenza, rispetto alle metodiche di emostasi convenzìonale. VenÌiòinque pazienti sono stati randomizzali per…

Hadronic Shower Development in Iron-Scintillator Tile Calorimetry

The lateral and longitudinal profiles of hadronic showers detected by a prototype of the ATLAS Iron-Scintillator Tile Hadron Calorimeter have been investigated. This calorimeter uses a unique longitudinal configuration of scintillator tiles. Using a fine-grained pion beam scan at 100 GeV, a detailed picture of transverse shower behavior is obtained. The underlying radial energy densities for four depth segments and for the entire calorimeter have been reconstructed. A three-dimensional hadronic shower parametrization has been developed. The results presented here are useful for understanding the performance of iron-scintillator calorimeters, for developing fast simulations of hadronic showe…
