Imaging of Gastrointestinal Stromal Tumors: From Diagnosis to Evaluation of Therapeutic Response

2016

Once considered an obscure tumor entity with poor prognosis, gastrointestinal stromal tumors (GISTs) are nowadays recognized as the most common mesenchymal tumors of the alimentary tract. GISTs differ from other mesenchymal neoplasms at pathology since 90% of them exhibit strong immunohistochemical staining for KIT, a tyrosinase kinase growth factor receptor. In the early 2000s, the ability of imatinib mesylate, a tyrosine kinase inhibitor, to inhibit KIT established a new paradigm for cancer treatment. A reduction in lesion size may not be observed or may appear many months after therapy; thus, tumor response criteria alternative to the Response Evaluation Criteria in Solid Tumors were dev…

Role of Octreotide, Scopolamine Butylbromide, and Hydration in Symptom Control of Patients with Inoperable Bowel Obstruction and Nasogastric Tubes

2000

Bowel obstruction may be an inoperable complication in patients with end-stage cancer. Scopolamine butylbromide (SB) and octreotide (OCT) have been successfully used with the aim of reducing gastrointestinal (GI) secretions to avoid placement of a nasogastric tube (NGT); however, there have been no comparative studies concerning the efficacy of these drugs. Furthermore, there is little information about the role played by parenteral hydration in symptom control of these patients. In a prospective trial that involved all 17 inoperable bowel-obstructed patients presenting to our services with a decompressive NGT, patients were randomized to OCT 0.3 mg/day or SB 60 mg/day for 3 days through a …

Prophylaxis In Congenital Factor VII Deficiency, Indications, Efficacy and Safety: Results of the STER

2010

Abstract Abstract 665 Introduction Prophylaxis is considered a difficult endeavour in FVII deficiency, especially because of the very short FVII zymogen and FVIIa half-lives, mainly in childhood. The Seven Treatment Evaluation Registry (STER, www.targetseven.org) is a prospective observational, multi-centre, web-based registry concerned with the evaluation of treatments for spontaneous bleeding episodes, surgery and prophylaxis in patients with FVII deficiency. As regards prophylaxis, STER provides the frame for a structured and detailed data capture aiming at: a) identifying patients in whom prophylaxis is advisable, b) defining clinical settings in which prophylaxis is necessary and c) de…

Prevention of Upper Gastrointestinal Bleeding in Cirrhotic Patients

1987

The prevalence of varices in patients with cirrhosis is stated to be about 50% and the risk of variceal bleeding 40% with mortality ranging from 30% to 60%. Differences may be due to patient selection and diagnostic criteria. The death risk of first bleeding seems to be higher than that of subsequent episodes (Christensen et al. 1981; D’Amico et al. 1986), indicating that the first bleeding episode causes a selection.

GASTROINTESTINAL COMPLICATIONS DURING USE OF ANTI-INFLAMMATORY DRUGS FOR ORTHOPEDIC DISEASES

2011

Non-Steroidal Anti-inflammatory Drugs (NSAIDs) are molecules that inhibit the functionality of cyclooxygenase, resulting in suppression of prostaglandin production. Primary physicians and specialist clinics frequently prescribe NSAIDs for the treatment of osteoarticular diaseases such as tendinitis, bursitis, synovitis, spondylitis and osteoarthritis. This analysis aims to study gastrointestinal complications in orthopedic patients, caused by the use of NSAIDs, employng esophagogastroduodenoscopy and colonoscopy.

THE ENTERIC NERVOUS SYSTEM: NEW DEVELOPMENTS AND EMERGING CONCEPTS

2011

The enteric nervous system (ENS) is an integrative neuronal network, organized in two ganglionated plexuses, myenteric and submucosal, composed of neurons and enteric glial cells, controlling the activity of the smooth muscle of the gut, mucosal secretion and blood flow. The ENS contains as many neurons as the spinal cord, and the functional and chemical diversity of enteric neurons closely resembles that of the central nervous system. This highly integrated neural system is also referred to as the ‘brain-in-the-gut’, because of its capability to function in the absence of nerve inputs from the central nervous system.

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 (…

Gene Signatures in Gastrointestinal Stromal Tumors

2011

Gastrointestinal stromal tumors (GISTs) constitute a rare heterogeneous group of the most common mesenchymal neoplasm of gastrointestinal tract (GI). GISTs have emerged during the recent years as a distinct sarcoma entity due to advances in the understanding of molecular mechanism of their pathogenesis. They are believed to originate from precursors shared with interstitial cells of Cajal (ICC) – the pacemaker cells of the gut (for which CD117 antigen is the immunohistochemical marker), and they may arise along all GI (most commonly in the stomach or the small bowel) or rarely elsewhere. Their biological behavior is difficult to predict, ranging from clinically benign to malignant. The trea…
