In vivo liver expression of TLR2, TLR3 and TLR7 in chronic hepatitis C
2013
The role of innate immune response mediated by Toll-like receptors in HCV infection, is not yet well understood and there is a lack of data regarding liver tissue expression of these molecules in chronic hepatitis C (CHC). Our study is aimed to investigate ex vivo, liver expression of TLR2, TLR3 and TLR7, which are more involved in the immune-pathogenesis of CHC, and to explore possible correlations with features of disease. We obtained liver biopsies and collected peripheral blood mononuclear cells (PBMC) from 23 consecutive patients with CHC and from 6 patients of control, without liver disease, undergoing surgery for cholecystectomy. The levels of TLRs mRNA in the samples were determined…
Does Ligasure(TM) Reduce Fluid Drainage in Axillary Dissection? A Randomised Prospective Clinical Trial
2007
Background: Axillary lymph node dissection (ALND) is an integral part of breast cancer treatment. It is required in about 40–50% of patients. The placement of a drain in the axilla after an operation is current surgical practice. Short surgical stay programmes increase operating efficiency and reduce medical care costs, without compromising quality of care. LigaSureTM is a new haemostatic device that uses bipolar energy to seal vessels. The aim of this study is to determine whether axillary dissection with LigaSureTM reduces the time of wound drainage, the duration of surgical intervention and the volume of drainage after treatment. Patients and methods: This study is a prospective randomiz…
Wider implications of video-assisted thoracic surgery versus open approach for lung metastasectomy
2015
ABSTRACT Lung metastasectomy is considered a safe and potentially curative procedure despite there is not a strong evidence that metastasectomy prolongs long-term survival in patients with lung metastases. Moreover, the debate is open regarding the best approach for lung metastasectomy, video-assisted thoracic surgery versus open approach. A systematic review of literature to clarify what is the best approach to prolong survival in patients with lung metastases was performed. Our study confirms that overall survival is equivalent for video-assisted thoracic surgery and thoracotomy, therefore the ‘gold standard’ surgical treatment for lung metastases remains a point of debate. The choice o…
Candida spp. infections after abdominal urgent surgery: comparative analysis of histologic data for which microbiological results were positive for C…

Rodolico1, G. Gulotta1, L. Montana1, G. Salamone1, D.C. Paola1 1Department of Sciences for Health Promotion and Mother Child Care, Palermo, Italy Objectives: Microbiological identification is justified when the yeast is isolated from a sterile site, the potential clinical impact of identified isolates from non sterile sites such as intra- abdominal organs don’t help the clinicians to determine whether the strain isolate represents contamination, colonizatio…
THE ROLE OF INFLAMMATION IN TYPE A AORTIC DISSECTION: A PILOT STUDY
2013
Type A aortic dissection (TAAD) is a severe cardiovascular disease with high mortality rates. Current evidence suggests inflammation as the main mechanism of its complex pathophysiology. Accordingly, in this study the eventual presence of inflammatory cells in aorta specimens and any contribution of these cells in both apoptosis and metalloproteinase levels were assessed. The potential relationship between plasma inflammatory molecules and TAAD was also detected. In addition, implication in TAAD susceptibility of ten common and functional single nucleotide polymorphisms (SNP)s of six candidate genes (CCR5, TLR4, ACE, eNOs, MMP-9 and −2) was determined. Thus, histo-pathological and immunois…
A Case of Follicular Tumor of Uncertain Malignant Potential (FT-UMP) with Glomeruloid Features Showing Capsular Mucinous Degeneration
2021
The most recent revision of the World Health Organization (WHO) Classification of Tumours of Endocrine Organs introduced a new variant of follicular thyroid carcinoma (FTC). It is characterized by a “glomeruloid” architectural pattern of growth. We present a case of follicular tumor with glomeruloid features, with Alcian Blue positive mucinous stromal degeneration in foci of questionable capsular microinvasion. At our knowledge, this the second case of glomeruloid follicular tumor in the literature and the first case in which Alcian Blue staining was used to investigate capsular invasion. Moreover, RAS mutation further supports that this is a variant of follicular tumor with uncertain malig…
Role of a medication in polyurethane foam in the treatment of diabetic foot lesions
2010
Background The treatment of diabetic foot lesions need medications capable of managing wound infection and exudates that, variously combined, can influence the natural history of the pathology and therefore limb survival. A particular and economic device, is represented by honeycomb structure polyurethane foam Ligasano ©.
Altered expression of inflammation-related genes in human carotid atherosclerotic plaques.
2011
Abstract Objective Inflammation is a pivotal process in atherosclerosis development and progression, but the underlying molecular mechanisms remain largely obscure. We have conducted an extensive expression study of atherosclerotic plaques to identify the inflammatory pathways involved in atherosclerosis. Methods We studied 11 human carotid plaques, their respective adjacent regions and 7 control arteries from different subjects. Expression of 92 genes was studied by TaqMan low-density array human inflammation panel. Human aortic endothelial and smooth muscle cells were used for in vitro experiments. Results The mRNA levels of 44/92 genes (48%) differed significantly between the tissues exa…
Adipose tissue, angiogenesis and angio-MIR under physiological and pathological conditions.
2019
Angiogenesis is a crucial process for the maintenance of normal tissue physiology and it is involved in tissue remodeling and regeneration. This process is essential for adipose tissue maintenance. The adipose tissue is composed by different cell types including stromal vascular cells as well as adipose stem cells (ASCs). In particular, ASCs are multipotent somatic stem cells that are able to differentiate and secrete several growth factors; they are recently emerging as a new cell reservoir for novel therapies and strategies in many diseases. Several studies suggest that ASCs have peculiar properties and participate in different disease-related processes such as angiogenesis. Furthermore, …
Anaesthetic-related neuroprotection: intravenous or inhalational agents?
2010
In designing the anaesthetic plan for patients undergoing surgery, the choice of anaesthetic agent may often appear irrelevant and the best results obtained by the use of a technique or a drug with which the anaesthesia care provider is familiar. Nevertheless, in those surgical procedures (cardiopulmonary bypass, carotid surgery and cerebral aneurysm surgery) and clinical situations (subarachnoid haemorrhage, stroke, brain trauma and postcardiac arrest resuscitation) where protecting the CNS is a priority, the choice of anaesthetic drug assumes a fundamental role. Treating patients with a neuroprotective agent may be a consideration in improving overall neurological outcome. Therefore, a cl…
