Two cases of monomicrobial intraabdominal abscesses due to KPC - 3 Klebsiella pneumoniaeST258 clone

2011

Abstract Background Knowledge of the etiology of pyogenic liver and pancreatic abscesses is an important factor in determining the success of combined surgical and antibiotic treatment. Literature shows geographical variations in the prevalence and distribution of causative organisms, and the spread of Klebsiella pneumoniae carbapenemase-producing bacteria is an emerging cause of abdominal infections. Case presentation We herein describe two cases of intra-abdominal abscesses due to monomicrobial infection by Klebsiella pneumoniae Sequence Type 258 producing K. pneumoniae carbapenemase 3 (KPC-Kp). In case 1, a 50-year-old HIV-negative Italian woman with chronic pancreatitis showed infection…

SARS-CoV-2 and its impact on the cardiovascular and digestive systems – The interplay between new virus variants and human cells

2023

Since infection with the novel coronavirus SARS-CoV-2 first emerged in Wuhan, China, in December 2019,the world has been battling the pandemic COVID-19. Patients of all ages and genders are now becoming infected with the new coronavirus variant (Omicron) worldwide, and its subvariants continue to pose a threat to health and life. This article provides a literature review of cardiovascular and gastrointestinal complications resulting from SARS-CoV-2 infection. COVID-19 primarily caused respiratory symptoms, but complications can affect many vital organs. SARS-CoV-2 binds to a human cell receptor (angiotensin-converting enzyme 2 – ACE2) that is predominantly expressed primarily in the heart a…

Laparoscopic approach in abdominal emergencies: a 5-year experience at a single center.

2012

Background. Laparoscopy is ever more common in both elective and emergency surgery. In fact, in abdominal emergencies it enables the resolution of preoperative diagnostic doubts as well as treatment of the underlying disease. We present a retrospective study of the results of a 5-year experience at a single center. Patients and methods. Between September 2006 and August 2011, 961 patients were treated via laparoscopy, including 486 emergency cases (15 gastroduodenal perforation; 165 acute cholecystitis; 255 acute appendicitis; 15 pelvic inflammatory disease and non-specific abdominal pain [NSAP]; 36 small bowel obstruction). All procedures were conducted by a team trained in laparoscopic su…

Clinical response to linaclotide at week 4 predicts sustained response in irritable bowel syndrome with constipation and improvements in digestive an…

2019

Background:Linaclotide is approved for the treatment of moderate-to-severe irritable bowel syndrome (IBS) with constipation (IBS-C) in adults. This study aimed to assess factors predictive of a clinical response and improvements in non-IBS symptoms with linaclotide treatment in a Spanish patient population.Methods:In this open-label phase IIIb study, patients with moderate-to-severe IBS-C received linaclotide 290 μg once daily for 12 weeks. The primary endpoint was clinical response at week 12, defined as &gt;30% reduction in IBS symptom severity score (IBS-SSS) or IBS-SSS &lt;75 plus self-reported response of feeling ‘better’ or ‘much better’ versus the baseline. Digestive nonintestinal an…

Effects of temperature on gastric evacuation rate and absorption and transport of dietary lipids in sea bass (Dicentrarchus labrax, L.)

1993

Abstract 1. 1. Gastric evacuation rate and lipid absorption and transport were studied in sea bass reared at 25°, 20° and 15°C. 2. 2. An increase in gastric evacuation and a reduction in lipid absorption were observed at the higher temperature. 3. 3. Lowering temperature (15°C), led to a decrease in the rate of gastric emptying, with a prolonged lipid absorption. 4. 4. Relationships between lipid absorption and gastric evacuation are discussed.

Endoscopic therapy of adenomas of the papilla of Vater. A retrospective analysis with long-term follow-up.

2001

Abstract Aims. To compare the efficacy and the complication rate between endoscopic snare resection of adenomas of Vater's papilla and endoscopic palliation. Methods. In a retrospective, non randomized manner, we compared long-term results of our endoscopic strategies in 36 patients with histologically confirmed adenoma of Vater's papilla submitted either to local endoscopic snare resection (n=18) or to simple endoscopic palliation (n=18), respectively. Results. Between 1985 and 1998 results were reviewed. Median age was 76.5 (range 42–89) years in the palliation, and 64.0(23–89) years in the endoscopic snare resection group. Median duration of follow-up was 33 (6–135) and 75.0 (27–123) mon…

Age-dependent shift-to-the-right in the localization of colorectal adenomas.

1987

The age-dependent prevalence and topographical distribution of colorectal adenomas was investigated in 1006 unselected autopsies (554 males and 452 females) in Mainz, FRG. In 200 out of 1006 autopsies (19.8%) a total of 498 adenomas of the large intestine were detected. The percentage of patients with adenomas increased continuously with age. Only 6% of all adenomas were localized in the caecum and 8% in the rectum, whereas all the other adenomas were distributed rather evenly throughout the ascending colon (23%), the transverse colon (25%), the descending colon (15%) and the sigmoid colon (23%). Analyzing the topographical distribution of adenomas for definite age groups (40-59, 60-69, 70-…

60KDa chaperonin (HSP60) is over-expressed during colorectal carcinogenesis

2003

The aim of the present study was to evaluate the expression of the heat shock protein 60 (HSP60), a mitochondrial matrix-associated protein belonging to the chaperonin family, in colorectal adenomas and cancers, comparing them to normal colonic tissues and hyperplastic polyps. We performed both immunohistochemistry and Western blot analysis for HSP60. Immunohistochemistry resulted positive in all tubular adenomas and infiltrating adenocarcinomas. By contrast, normal tissues and hyperplastic polyps were negative. Quantitative analysis showed that tubular adenomas with different levels of dysplasia did not present statistical differences concerning HSP60 positivity. In addition, carcinomas al…
