Il ruolo della manometria intraoperatoria nel trattamento chirurgico dell'acalasia esofagea
2008
Versione italiana Introduzione. Gli Autori riportano i risultati della loro esperienza sul ruolo della manometria intraoperatoria (MI) nel trattamento chirurgico dell'acalasia. Pazienti e metodi. Sono stati presi in considerazione 239 pazienti affetti da acalasia osservati dal 1994 al 2006; solo 79 hanno continuato l'iter diagnostico-terapeutico e 31 sono stati sottoposti ad intervento chirurgico di miotomia longitudinale secondo Heller, associando in 25 una plastica antireflusso secondo Dor e in 6 una plastica antireflusso secondo Nissen. In 24 pazienti su 31 è stata eseguita una MI con la individuazione delle zone di alta pressione (HPZ). Risultati. I pazienti sottoposti ad intervento di …
INTRODUCING NON-ADHERENT PROGENITORS FROM ADIPOSE-DERIVED STEM CELLS (NAPADSCS): PROOF OF STEMNESS AND POSSIBLE FUTURE APPLICATIONS IN REGENERATIVE S…
2012
Introduction: Mesenchymal Stromal Cells (MSCs) can be isolated from adipose tissue and are currently used in vitro for experimental studies. MSCs are often mislabeled as Adipose-derived Stem Cells (ADSCs) despite presenting a more differentiated phenotype. The isolation and expansion of non-adherent progenitors from adipose-derived stem cells (napADSCs), has been achieved in our laboratory and is currently under investigation. In this study we investigate: a) the proof of stemness of such progenitors, and b) the feasibility of napADSCs adhesion over Integra® for cell colonization and for future differentiation and engineering of semi-synthetic tissues. Material and Methods: Adipose tissue (…
Giant condylomata (Buschke-Löwenstein tumours): our case load in surgical treatment and review of the current therapies.
2012
BACKGROUND: Buschke-Löwenstein tumour (BLT) or giant condyloma is a verrucous infiltrating lesion, due to a sexually transmitted virus infection, human papilloma virus subtypes 6 and 11. Poor hygiene, promiscuity, chronic irritation and cellular immunocompromised states are often implicated in its genesis. Typical treatment of giant condyloma includes imiquimod cream, podophillin resin, cryotherapy, laser surgery, tangential shave excision with electrocautery. OBJECTIVE: The authors report their case load in the treatment of giant condyloma and the review of the modern therapies. METHODS AND MATERIALS: 27 consecutive patients (18 men, nine women) underwent surgery for giant condylomata of p…
Dupuytren's contracture as result of prolonged administration of phenobarbital
2011
Dupuytren's disease is a fibroproliferative condition involving the superficial palmar fascia, leading to a progressive and irreversible flexion of the fingers. In literature, there are different opinions regarding the phenobarbital, a common antiepileptic drug, and its effective role in the genesis and development of Dupuytren's disease. In this retrospective investigation the association between phenobarbital and Dupuytren's contracture is discussed.Three patients in treatment with phenobarbital who had no others significant risk factors for Dupuytren's contracture were included in this study. The disease occurred after one to four years of drug therapy, at dosage of 100 mg/day. After sur…
Hydrogel scaffolds blends to host Spheroids from human adipose stem cells
INTRODUCTION Adipose stem cells represent a reliable source of stem cells for their widely demonstrated potential in regenerative medicine and tissue engineering applications. New recent insights show that 3D models may properly mimic the native tissue properties; in fact Spheroids from Adipose derived Stem Cells (S-ASCs) displayed enhanced regenerative abilities if compared to 2D models. Stem cell therapy success is determined by "cell-quality" thus the involvement of stress signals and cellular aging need to be deeply investigated. The development of 3D cell-laden hydrogels has enabled to mimic the peculiar scenario of a native tissue. We studied SASCs-cell quality and tested their viabil…
Studio dell'infiltrato linfocitario peritumorale e dei linfociti circolanti in pazienti affetti da melanoma cutaneo
2014
I linfociti T γδ sono un gruppo di effettori “natural killer” del sistema immunitario innato che hanno rappresentato un interessante oggetto di studio nel corso degli ultimi anni. Il Dipartimento di Discipline Chirurgiche, Oncologiche ed Odontostomatologiche del Policlinico Universitario di Palermo, da anni attivo nei confronti della ricerca scientifica, ha recentemente condotto uno studio mirato alla conoscenza del potenziale effetto immunoterapeutico di questa popolazione linfocitaria verso i melanomi in stadio avanzato. Sulla base della classificazione della American Joint Committee on Cancer (AJCC) i pazienti affetti da melanoma maligno in stadio IV con neoplasia metastatica hanno una p…
