L'Epiploite acuta segmentaria è fra le cause più rare di addome acuto nell'infanzia. Gli Autori ne riportano tre casi.
Imaging features of adrenal masses
2019
Abstract The widespread use of imaging examinations has increased the detection of incidental adrenal lesions, which are mostly benign and non-functioning adenomas. The differentiation of a benign from a malignant adrenal mass can be crucial especially in oncology patients since it would greatly affect treatment and prognosis. In this setting, imaging plays a key role in the detection and characterization of adrenal lesions, with several imaging tools which can be employed by radiologists. A thorough knowledge of the imaging features of adrenal masses is essential to better characterize these lesions, avoiding a misinterpretation of imaging findings, which frequently overlap between benign …
A Good Breath of Oxygen for Beta-Like Cells Obtained From Porcine Exocrine Pancreatic Tissue
2011
Ischemia is the most important factor that affects organ survival during harvesting. The two-layer method (TLM) is one of several cold storage solutions that seeks to preserve organs and cells avoiding in vivo and in vitro ischemia. We compared the retrieval of beta-like elements from exocrine pancreatic cells using TLM versus University of Wisconsin (UW) solutions. For this purpose pancreata laparoscopically harvested from 20 female pigs were preserved in UW solution or TLM before digestion. The resulting exocrine cells were divided into 2 groups: the first was cultured in a designed medium to allow differentiation into beta-like cells and the second was cryopreserved before the differenti…
3D in Suspension versus 2D in Adhesion: molecular profiles in stemness and mesenchymal differentiation of Spheroids from Adipose-derived Stem Cells
2021
Purpose: Adipose stem cells (ASCs) represent a reliable source of stem cells with a widely demonstrated potential in regenerative medicine and tissue engineering applications. New recent insights suggest that three-dimensional (3D) models may closely mimic the native tissue properties; spheroids from adipose derived stem cells (S-ASCs) exhibit enhanced regenerative abilities compared with those of 2D models. Stem cell therapy success is determined by “cell-quality”; for this reason, microRNA profiles, the involvement of stress signals and cellular aging need to be further investigated. Material and Methods: Adipose tissue was collected from healthy individuals, 44 females and 17 males, afte…
Aneurysm clipping following endovascular coil embolization: A report of two cases
2009
Abstract BACKGROUND: Treatment of intracranial aneurysms by Guglielmi detachable coil (GDC) embolization is a useful therapeutic alternative to surgery. This procedure is attractive as a minimally invasive approach to treat cerebral aneurysms; however, is not devoid of complications or failure and retreatment, with either a surgical or endovascular technique, may often be required. CASE REPORTS: Two cases are presented in which surgery was required after coil embolization. In one case, surgical treatment was performed one month later because of regrowth and subsequent bleeding of the aneurysm. In the second case, surgical treatment was carried out six months later because of recanalization …
Different types of intestinal atresia in identical twins
2008
The authors present a previously unreported association of different types of intestinal atresia in identical low-birth-weight twins. Both babies were affected by duodenal atresia, associated in the first case with a complete mucosal duodenal membrane and in the second one with an "apple-peel" jejunal atresia. These occurrences may suggest that they were either the consequence of linkage of 2 genes or a pleiotropic expression of a single gene responsible for such rare conditions.
Laparoscopic, three-port and SILS cholecystectomy: a retrospective study.
2014
Introduction. The aim of this study was to compare the results of classic laparoscopic, three-port and SILS cholecystectomy. Materials and methods. We conducted a retrospective study of da- ta collected between January 2010 and December 2012 pertaining to 159 selected patients with symptomatic gallstones. 57 underwent lapa- roscopic cholecystectomy, 51 three-port cholecystectomy and 48 SILS cholecystectomy. We then compared the groups with respect to mean ope- rating time, intraoperative complications, postoperative pain, duration of hospitalization and final aesthetic result. Introduction The first laparoscopic cholecystectomy was carried out in 1987 in France by Philippe Mouret (1). The p…
Ultrasonography-guided central venous catheterisation in haematological patients with severe thrombocytopenia
2012
BACKGROUND: Cannulation of the internal jugular vein (CVC) is a blind surface landmark-guided technique that could be potentially dangerous in patients with very low platelet counts. In such patients, ultrasonography (US)-guided CVC may be a valid approach. There is a lack of published data on the efficacy and safety of urgent US-guided CVC performed in haematological patients with severe thrombocytopenia. MATERIALS AND METHODS: We retrospectively studied the safety of urgent CVC procedures in haematological patients including those with severe thrombocytopenia (platelet count <30×10(9)/L). From January 1999 to June 2009, 431 CVC insertional procedures in 431 consecutive patients were evalu…
ROUTINARY USE OF FIBRIN SEALANTS TO PREVENT PROLONGED AIR LEAK IN THORACIC SURGERT: OUR EXPERIENCE
2019
Introduction: prolonged air leak (PAL) is one of the most common postoperative complications after lung surgery. It is associatred with increased significant morbidity, lower quality of life, longer hospital stay and higher hospital costs. Since its great clinical and economic burden, it is important to establish the feasibility and the effectiveness of the routinary preventive use of a fibrin sealant in order to reduce the incidence of prolonged air leaks. Patients and methods: this is a randomized study on 189 adult patients - 118 men (62,4%) and 71 women (37,6%) aged from 39 to 87 y.o. (mean age 68,3 y.o.) - who underwent lung surgery (lobectomy or bilobectomy) with intraoperatory detect…
