Dihydrocucurbitacin B, isolated from Cayaponia tayuya, reduces damage in adjuvant-induced arthritis

2005

23,24-Dihydrocucurbitacin B, from the anti-rheumatic plant Cayaponia tayuya, was tested on arthritis induced by adjuvant to corroborate the anti-inflammatory properties of this plant. Arthritis was induced in Lewis rats; the resulting arthritic rats were then treated with dihydrocucurbitacin B (1 mg/kg orally, daily, 1 week). The effect of dihydrocucurbitacin B on the synthesis, release, and activity of pro-inflammatory enzymes (elastase, cyclooxygenase-2, and nitric oxide synthase-2) as well as its effect on different mediators (tumor necrosis factor-alpha and interleukin-1beta) were determined. Dihydrocucurbitacin B modified the evolution of the clinical symptoms, reducing the swelling an…

Effectiveness of Enteric-Coated Preparations on Nutritional Parameters in Cystic Fibrosis

1988

To evaluate the effectiveness of enteric-coated pancreatic enzyme supplements in comparison to conventional preparations of ingested enzyme on growth and nutritional parameters of patients with cystic fibrosis, we conducted a long-term study involving 40 patients. The data reproduced here were recorded after 6 months of therapy with powder-containing capsules or with enteric-coated products. Fat absorption was estimated by measurement of steatorrhoea with the steatocrit method. All parameters studied improved after enteric-coated pancreatic enzyme therapy, with a statistically significant increase in weight, cholesterol and haemoglobin values. Furthermore, the number of patients with positi…

Moderne Diagnostik zystischer Leberläsionen und Hämangiome

2015

Clinical issue: Cystic liver lesions incorporate a broad heterogeneous group of mostly benign but also malignant abnormalities. The radiological aim is the non-invasive diagnosis with the use of different imaging modalities to determine the type of lesion.Standard radiological methods: The common generally asymptomatic incidental findings of cystic lesions on ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI) must be classified on the basis of specific imaging features. Such a differentiation is essential because the clinical consequences and the appropriate therapy can vary depending on the underlying pathology. Due to the morphological overlap of many cystic lesions…

Cholangitis prevention in endoscopic Klatskin tumor palliation: air cholangiography technique.

2009

INTRODUCTION: Endoscopic biliary drainage is the treatment of choice for inoperable hilar cholangiocarcinoma (so-called Klatskin tumor). Cholangitis is the main complication post-endoscopic retrograde cholangiopancreatography (ERCP) in Klatskin patients, specially when medium contrast is injected into biliary tree that could not be subsequently drained. Bacterial cholangitis is the principal cause of mortality in these patients. The aim of this study is to analyze cholangitis rate resulting from the use of air versus iodine contrast to obtain cholangiography during ERCP. METHODS: In 9 years, 188 inoperable Klatskin patients were recruited and divided into two groups: iodine (A) or air (B) c…

Role of fluorine 18 fluorodeoxyglucose positron emission tomography/computed tomography in gastrointestinal cancers

2015

AbstractFluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) has become a routine imaging modality for many malignancies and its use is currently increasing. In the present review article, we will summarize the evidence for FDG-PET/CT use in digestive cancers (excluding neuroendocrine tumours), and review the existing recommendations. While PET/CT is nowadays considered to be an important tool in the initial workup of oesophageal and anal cancers, new data are emerging regarding its use in assessing therapeutic efficacy, radiotherapy treatment planning, and detection of recurrence in case of isolated tumour marker elevation. Moreover, PET/CT may help …

The Value of BISAP Score for Predicting Mortality and Severity in Acute Pancreatitis: A Systematic Review and Meta-Analysis

2015

Purpose The Bedside Index for Severity in Acute Pancreatitis (BISAP) score has been developed to identify patients at high risk for mortality or severe disease early during the course of acute pancreatitis. We aimed to undertake a meta-analysis to quantify the accuracy of BISAP score for predicting mortality and severe acute pancreatitis (SAP). Materials and Methods We searched the databases of Pubmed, Embase, and the Cochrane Library to identify studies using the BISAP score to predict mortality or SAP. The pooled sensitivity, specificity, likelihood ratios, and diagnostic odds ratio (DOR) were calculated from each study and were compared with the traditional scoring systems. Results Twelv…

Isolation and colture of beta-like cells from porcine Wirsung duct

2009

We sought to develop a protocol to isolate and culture porcine Wirsung duct cells in order to determine their potency to differentiate into insulin-expressing beta-like cells. The porcine Wirsung duct isolated by a surgical microdissection was digested with collagenase P and trypsin to dissociate ductal cells. These elements were cultured in serum-free supplemented media: for 2 weeks. Thereafter the cells were exposed to varying concentrations of glucose (0, 5.6, 17.8, and 25 mmol/L) to induce a beta-like phenotype, as identified by immunohistochemical staining. Cell growth proceeded slowly for the first 2 weeks of culture. After glucose induction for 2 weeks, they formed pancreatic islet-l…

Current status on the adoption of high energy devices in Italy. An Italian Society for Endoscopic Surgery and New Technologies (SICE) national survey

2021

Background: In the past three decades, different High Energy Devices (HED) have been introduced in surgical practice to improve the efficiency of surgical procedures. HED allow vessel sealing, coagulation and transection as well as an efficient tissue dissection. This survey was designed to verify the current status on the adoption of HED in Italy. Methods: A survey was conducted across Italian general surgery units. The questionnaire was composed of three sections (general information, elective surgery, emergency surgery) including 44 questions. Only one member per each surgery unit was allowed to complete the questionnaire. For elective procedures, the survey included questions on thyroid…

Biliary complications after liver transplantation: current perspectives and future strategies

2021

Importance: Liver transplantation (LT) is a life-saving therapy for patients with end-stage liver disease and with acute liver failure, and it is associated with excellent outcomes and survival rates at 1 and 5 years. The incidence of biliary complications (BCs) after LT is reported to range from 5% to 20%, most of them occurring in the first three months, although they can occur also several years after transplantation.Objective: The aim of this review is to summarize the available evidences on pathophysiology, risk factors, diagnosis and therapeutic management of BCs after LT.Evidence Review: a literature review was performed of papers on this topic focusing on risk factors, classificatio…
