Gender representation in authorship in later-phase systemic clinical trials in biliary tract cancer (BTC).

2021

348 Background: The proportion of females in medicine is increasing (approx. 50% in medical school/workforce), but disparities in female authorship in oncology research publications exist; female corresponding authorship reportedly ranges from 7.2-39.1% in oncology clinical trials (Ludmir et al 2019). This study aimed to describe and assess factors associated with female first and senior authorship in later phase systemic clinical trials in BTC and to identify any changes over time. Methods: Embase/Medline were used to identify final primary trial publications in BTC (2000-2020) (excluding phase I (PI) (expected to move to later phase), mixed tumour site trials, reviews, editorials and tri…

Prevalence of biliary lithiasis in the elderly people of a small town in Sicily

1992

The aim of the present study was to determine the prevalence of biliary lithiasis (BL) and its major associated factors in the elderly people of a small town in Sicily. All inhabitants over the age of 65 were interviewed and underwent a general physical examination, blood tests and ultrasonography of the gallbladder and biliary tracts. The final group included 328 subjects (162 men and 166 women), representing 63.1% of the population asked to participate, with a mean age of 74.3 +/- 6.8 years (range 65-95). The prevalence of BL (lithiasis in progress + subjects cholecystectomized for previous calculosis) was 18.6%. No male subject had been cholecystectomized. Prevalence was higher in women …

Cellular cytotoxicity against autologous hepatocytes in alcoholic liver disease.

2008

We tested lymphocyte cytotoxicity against autologous hepatocytes in patients with alcoholic liver disease (ALD). The following cytotoxicity values were found (mean +/- SEM): alcohol-induced steatosis with or without fibrosis 16.5 +/- 2% (n = 29), alcoholic cirrhosis 28 +/- 4% (n = 13), controls with normal liver histology or minimal changes 6 +/- 2% (n = 11). The differences were statistically significant (both forms of ALD versus controls p less than 0.005). T-cell as well as non-T-cell-enriched lymphocyte fractions showed increased cytotoxicity in ALD. We did not observe a correlation between cellular cytotoxicity and the degree of biochemical or histological alterations within the groups…

Identification of target antigen for SLA/LP autoantibodies in autoimmune hepatitis.

2000

Summary Background Autoantibodies are a hallmark of autoimmune hepatitis, but most are not disease specific. Autoantibodies to soluble liver antigen (SLA) and to liver and pancreas antigen (LP) have been described as disease specific, occurring in about 30% of all patients with autoimmune hepatitis, but no standardised assays are available. Methods We tested 2000 serum samples from patients with various liver diseases and controls for SLA autoantibodies by inhibition ELISA. Serum samples positive for SLA antibodies were used for immunoscreening of cDNA expression libraries. Identified clones were tested against a panel of serum samples positive for SLA and LP autoantibodies and control seru…

ILEO BILIARE: DIAGNOSI E TRATTAMENTO. CASE REPORT

2006

The authors present a case of gallstone intermittent ileus caused by the passage of a big gallstone (about 4 cm in diameter) in the intestinal lumen, through a cholecystoduodenal fistula. They emphasize the peculiarity of the case for the characteristics of symptoms and for casual diagnostic check-up with a ultrasonography. The disease is not frequently diagnosed; today it has a safe recognition by modern imaging. The symptoms can be intermittent and, even when there are the classic signs of intestinal occlusion, the site of the occlusion is various. With a timely endoscopical or surgical approach (open or laparoscopic) it is possible to reduce mortality of patients treated in emergency.

Biliopancreatic Endoscopy in Altered Anatomy

2021

Background and Objectives: Anatomical post-surgical alterations of the upper gastrointestinal (GI) tract have always been challenging for performing diagnostic and therapeutic endoscopy, especially when biliopancreatic diseases are involved. Esophagectomy, gastrectomy with various reconstructions and pancreaticoduodenectomy are among the most common surgeries causing upper GI tract alterations. Technological improvements and new methods have increased the endoscopic success rate in these patients, and the literature has been rapidly increasing over the past few years. The aim of this systematic review is to identify evidence on the available biliopancreatic endoscopic techniques performed i…

Double-balloon endoscopy for retrograde cholangiography in patients with choledochojejunostomy and Roux-en-Y reconstruction.

2009

BACKGROUND Choledochojejunal anastomoses with Roux-en-Y reconstruction excludes the biliary tract from conventional endoscopic retrograde cholangiography (ERC) with standard endoscopes due to the length of the interposed small bowel segment. Double-balloon enteroscopy (DBE) facilitates deep insertion into the small bowel and may be used to perform ERC in these patients. In the present case series we report our experience with diagnostic and therapeutic double-balloon ERC in patients with choledochojejunostomy to a long Roux-en-Y loop previously unavailable for standard length endoscopes. PATIENTS AND METHODS Between December 2004 and May 2008 15 patients (mean age: 60.2 years) with choledoc…

Xenobiotic Metabolism

1999

Publisher Summary This chapter reveals that one's body takes up significant amounts of material that are used neither as energy substrates nor as building blocks for biological matrices. Uptake of such xenobiotica occurs mainly with the food but also by inhalation or transdermally. If these compounds accumulated in the organism, the resulting body burden would have been enormous. Thus, efficient mechanisms for the excretion of such compounds that have their roots very early in the evolution of life have developed. The two major elimination pathways in humans are excretion via bile and excretion via urine. For volatile compounds, exhalation can represent the dominant mechanism of excretion. …
