Intestinal ultrasonography has emerged as a cheap, non-invasive and readily accessible modality for the assessment of a number of gastroenterological diseases. Over the last decade, particularly due to the widespread use of biological agents in Inflammatory Bowel Disease (IBD), guidelines regarding management and follow-up advise more regular disease assessment and surveillance in order to guide treatment adjustments, and provide more personalised care. Given the young age of the majority of patients with IBD the availability of an alternative modality to harmful radiation or the risks of endoscopy for this indication offers an appealing advantage...

Paediatric magnetic resonance enterography (MRE) has been increasingly employed in the evaluation of inflammatory bowel disease (IBD) in the past decade. This is in parallel with a global rise in paediatric-onset IBD, greater recognition of the hazards of ionizing radiation, especially in children, and improved treatment options. MRE is now the reference standard for assessing the small bowel in suspected or proven paediatric IBD, and is central to the diagnosis of Crohn's disease (CD), helping distinguish it from ulcerative colitis...

Radiotherapy-induced damage to non-cancerous gastrointestinal mucosa has effects on secretory and absorptive functions and can interfere with normal gastrointestinal physiology. Nutrient absorption and digestion may be compromised. Dietary manipulation is an attractive option with sound rationale for intervention. The aim of this review was to synthesise published evidence for the use of elemental formulae, low or modified fat diets, fibre, lactose restriction and probiotics, prebiotics and synbiotics to protect the bowel from gastrointestinal side effects during long-course, radical pelvic radiotherapy...

OBJECTIVES: Patients with inflammatory bowel disease(IBD) are frequently exposed to computed tomography (CT). Each CT exposes patients to radiation that cumulatively could increase the risk of malignancy, particularly in younger patients. We aim to study the effect of age on CT use in IBD patients seen in the Emergency Department (ED) or the hospital. METHODS: We conducted a retrospective cohort study of IBD patients identified in Truven Health Marketscan databases between 2009-2013...

J Wessling
BACKGROUND: Computed tomography (CT) is often used as the initial diagnostic test in patients with inflammatory and infectious types of enterocolitis. The differential diagnosis is broad, including infectious, non-infectious and vascular causes, which have substantially different management strategies. Although a definitive diagnosis often relies on endoscopic biopsy results, stool culture results or other clinical features, radiologists often help to guide the diagnosis. OBJECTIVES: This article reviews the CT appearance of different infectious and inflammatory forms of enterocolitis...

AIM: To design colon-targeted codrugs of mycophenolic acid (MPA) and aminosugars as a safer option to mycophenolate mofetil (MMF) in the management of inflammatory bowel disease. METHODS: Codrugs were synthesized by coupling MPA with aminosugars (D-glucosamine and D-galactosamine) using EDCI coupling. The structures were confirmed by infrared radiation, nuclear magnetic resonance, mass spectroscopy and elemental analysis. The release profile of codrugs was extensively studied in aqueous buffers, upper gastrointestinal homogenates, faecal matter and caecal homogenates ( in vitro ) and rat blood ( in vitro )...

REVIEW
Inês Pita, Fernando Magro
Treatment of Crohn's disease (CD) is intrinsically reliant on imaging techniques, due to the preponderance of small bowel disease and its transmural pattern of inflammation. Ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI) are the most widely employed imaging methods and have excellent diagnostic accuracy in most instances. Some limitations persist, perhaps the most clinically relevant being the distinction between inflammatory and fibrotic strictures. In this regard, several methodologies have recently been tested in animal models and human patients, namely US strain elastography, shear wave elastography, contrast-enhanced US, magnetization transfer MRI and contrast dynamics in standard MRI...

As many as 40% of men diagnosed with prostate cancer have low-risk disease, which results in the need to decide whether to undergo active treatment (AT) or active surveillance (AS). The treatment decision can have a significant effect on general and prostate-specific quality of life (QOL). The purpose of this study was to assess the QOL among men with low-risk prostate cancer during the first year following diagnosis. In a prospective cohort study, we conducted pretreatment telephone interviews (N = 1,139; 69...

INTRODUCTION: The obturator hernia is a rare pelvic hernia that often comes in the shape of bowel obstruction caused by the presence of an intestinal segment, more often ileum, passing trough the obturator foramen of the pelvic wall (Fig. 1). This type of hernia accounts for 0.5-1.4% of all hernias. CASE PRESENTATION: We report the clinical case of a 84-year-old woman with no previous surgical interventions, who went to the emergency room complaining of vomit and nausea, bowels closed to gas and stool, which she had experienced for three previous days...

RATIONALE: Heterotaxy with polysplenia is an extremely rare congenital condition resulting from abnormal arrangement of organs in the abdominal and thoracic cavities during embryologic development. When a malignancy such as pancreatic cancer develops under these conditions, surgical resection becomes particularly complex. This case report demonstrates successful pancreatic cancer resection despite the patient's complicated anatomy. PATIENT CONCERNS: An 82-year-old female presented to our institution with complaints of mild right upper quadrant pain radiating to the mid-epigastric region...
