Hydro-MRT mit schnellen Sequenzen bei Morbus Crohn: Vergleich mit der fraktionierten Magen-Darm-Passage
2008
PURPOSE To compare the value of hydro-MRI with that of barium studies in patients with Crohn's disease. MATERIALS AND METHODS After an oral bowel opacification using 1000 ml of a 2.5% mannitol solution, axial and coronal breath-hold sequences (T2W HASTE +/- FS, contrast-enhanced T1W FLASH FS) were acquired in 46 patients with Crohn's disease at 1.0 T. The findings of hydro-MRI were compared with those of barium studies. RESULTS In the stomach and the small bowel, hydro-MRI and barium studies demonstrated similar numbers of Crohn's involvements (39 vs. 36); in the colon, hydro-MRI showed clearly more affections (23 vs. 10). Hydro-MRI showed 12.7 cm of inflamed bowel per patient, on average (…
Morphometrische Untersuchungen an Darminterponaten nach totaler Gastrektomie
1982
Im Tierexperiment wurden nach totaler Gastrektomie die Bildung eines Ersatzmagens mit verschiedenen Darminterponaten sowie der Oesophago-Jejunostomie mit Roux-Y-Anastomose durchgefuhrt. Bei der Relaparotomie nach 3monatiger postoperativer Uberlebenszeit wurden die Interponate an ausgewahlten Stellen morphometrisch untersucht. Als deutlichste Veranderung fiel bei allen Dunndarmersatzmagen eine starke muskulare Wandhypertrophie auf, die vor allem die Ringmuskulatur betraf. Beim Colonersatzmagen, der physiologisch eine dickere Wandmuskulatur besitzt, war die Hypertrophie sehr viel geringer. Als pathogenetischer Faktor dieser Veranderung gilt die Volumenbelastung, der der Ersatzmagen an dieser …
New insights into the gut microbiome in loggerhead sea turtles Caretta caretta stranded on the Mediterranean coast
2019
Caretta caretta is the most common sea turtle species in the Mediterranean Sea. The species is threatened by anthropomorphic activity that causes thousands of deaths and hundreds of strandings along the Mediterranean coast. Stranded turtles are often cared for in rehabilitation centres until they recover or die. The objective of this study was to characterize the gut microbiome of nine sea turtles stranded along the Sicilian coast of the Mediterranean Sea using high-throughput sequencing analysis targeting V3–V4 regions of the bacterial 16S rRNA gene. Stool samples were collected from eight specimens hosted in the recovery centre after a few days of hospitalization (under 7) and from one ho…
Evaluation of Esophageal Motility Using Multichannel Intraluminal Impedance in Healthy Children and With Gastroesophageal Reflux
2010
Abstract OBJECTIVE: : Multichannel intraluminal impedance (MII) directly evaluates esophageal bolus transport. There is a good correlation between MII and manometry in healthy adults, but there are no reports concerning children.The aim of the present study was to determine normal values of esophageal motility using only impedance measurements in healthy children and in a pediatric population with gastroesophageal reflux (GER). PATIENTS AND METHODS: : We described in the present study 60 children submitted to pH-MII for 24 hours for suspected GER. Patients were divided into 2 different groups on the basis of their pH-MII report. Group 1 patients showed acid GER, whereas group 2 patients had…
The Gut Microbiota as an Influencing Factor of Arterial Thrombosis
2018
The mutualistic gut microbiota does not only impact the development and function of various immune cell types, but it also influences the function of the hepatic vascular endothelium and prothrombotic platelet function. With germ-free mouse models, we have demonstrated that gut-derived microbial-associated molecular patterns could stimulate hepatic von Willebrand factor (VWF) synthesis and plasmatic VWF levels through Toll-like receptor-2 (TLR2), thus defining the extent of platelet deposition to the subendothelial matrix of the ligation-injured common carotid artery. In addition to the microbiota-derived choline metabolite trimethylamine N-oxide and the microbiota's regulatory role on the …
Regulatory cytokine gene polymorphisms and risk of colorectal carcinoma.
2006
It is well established that cancer arises in chronically inflamed tissue, and this is particularly notable in the gastrointestinal tract. Classic examples include Helicobacter pylori-associated gastric cancer, hepatocellular carcinoma, and inflammatory bowel disease-associated colorectal cancer. Growing evidence suggests that these associations might be not casual findings. Focusing on individual cytokines has generated evidence that anti-inflammatory cytokine interleukin (IL)-10 and transforming growth factor-beta1 (TGF-beta1) may have a complex role in gastrointestinal carcinogenesis. As an example, IL-10-deficient mice develop severe atrophic gastritis and a chronic enterocolitis, develo…
IL-12 family members in experimental colitis
2008
Interleukin (IL)-12 p35/p40 is a heterodimeric cytokine that plays an important role in T helper (Th) cell polarization and Th1 T-cell differentiation. Recent findings have shown that both p35 and p40 can form other cytokines with different proteins (IL-23: p19/p40; IL-35: p35/EBI3). Furthermore, the cytokine IL-27 (EBI3/p28) has been identified as a member of the IL-12 family. Here, we discuss the recent findings on the role of IL-12 family members in experimental colitis. In particular, the role of IL-23 as a master regulator of effector T-cell activation is highlighted. These findings have important implications for the design of new therapeutic approaches in chronic intestinal inflammat…
Early miR-223 Upregulation in Gastroesophageal Carcinogenesis
2017
Objectives: To test miR-223 upregulation during gastric (intestinal-type) and Barrett esophageal carcinogenesis. Methods: miR-223 expression was assessed by quantitative reverse transcription polymerase chain reaction in a series of 280 gastroesophageal biopsy samples representative of the whole spectrum of phenotypic changes involved in both carcinogenetic cascades. The results were further validated by in situ hybridization on multiple tissue specimens obtained from six surgically treated gastroesophageal adenocarcinomas. miR-223 expression was also assessed in plasma samples from 30 patients with early stage (ie, stages I and II) gastroesophageal adenocarcinoma and relative controls. Res…
Subtotal esophageal resection in motility disorders of the esophagus.
2005
<i>Background:</i> Esophagectomy for motility disorders is performed infrequently. It is indicated after failed medical therapy, pneumatic dilation, non-resecting surgical and redo procedures. Patient selection in this group is challenging and the operative risk has to be weighted carefully against the poor quality of life with persistent or recurrent dysphagia. <i>Patients and Methods:</i> Between September 1985 and April 2004, subtotal esophageal resections for advanced esophageal motility disorders of the esophagus not responding to previous therapy were carried out in 8 patients (6 females, 2 males). The median age of these patients was 59.5 (43–78) years. Six pa…
CROHN'S DISEASE AND EXTRAINTESTINAL GRANULOMATOUS LESIONS
2018
Crohn's disease (CD) is an inflammatory bowel disease with a multifactorial etiology. Clinical features include mucosal erosion, diarrhea, weight loss and other complications such as formation of granuloma. in CD, granuloma is a non-neoplastic epithelioid lesio, formed by a compact aggregate of histiocytes with the absence of a central necrosis, however, the correlation amomg CD and the formation of granulomas is unknown. Many casesof granulomas in the extracellular site, related to Cd, have been reported in the literature. These granulomas, at times, rapresented the only visible manifestation of the pathology. extra intestinal granuloma have been found on ovaries, lungs, male genitalia, fe…
