BACKGROUND: Ultrasound is accurate in the detection of Crohn's disease. Our aim was to identify ultrasound parameters contributing to inflammatory disease activity, develop a simple score, and validate this score prospectively. METHODS: This study comprised 2 single-center investigations. The first was a retrospective study on a population that had received colonoscopies (as a gold-standard diagnostic) within 60 days of ultrasound. The second was a prospective study on 2 populations: patients requiring induction with adalimumab and patients on adalimumab maintenance therapy...

Huei-Wen Lim, Keith S Sultan
BACKGROUND Sclerosing mesenteritis (SM) is a rare idiopathic inflammation and fibrosis of the mesentery. Its etiology and pathogenesis remain unclear. It has been linked to abdominal trauma related to peritoneal dialysis, recent abdominal surgery, idiopathic inflammatory disorder, paraneoplastic syndrome, ischemia/infection, and autoimmunity. Abdominal CT is the most sensitive imaging modality, and diagnosis is usually confirmed by surgical biopsy. Patients most often present with abdominal pain, nausea, vomiting, diarrhea, and weight loss, and less commonly with chylous ascites and small bowel obstruction...

BACKGROUND: Increased delivery of taurine-conjugated bile acids to the distal bowel can lead to dysbiosis resulting in colitis in mouse models of inflammatory bowel disease. A similar situation also could occur in cats with intestinal disease and might therefore result in decreased whole-body taurine concentration. HYPOTHESIS/OBJECTIVES: To determine whether whole-blood taurine concentrations are decreased at the time of diagnosis in cats with intestinal disease and to correlate concentrations with clinical and laboratory variables...

BACKGROUND: Hepatic portal venous gas (HPVG) is a rare imaging finding in children. It can be an important manifestation of severe diseases such as necrotizing enterocolitis (NEC) in neonates or bowel wall rupture in older children. However, there are many other diseases presenting with HPVG that do not necessarily require a surgical intervention. CASE REPORT: In the period between 2011-2015, there were 12 cases of HPVG in children aged up to 24 months in our hospital...

Ultrasound (US) is the first-line investigation in patients with abdominal symptoms and it has a role in the diagnosis and monitoring of inflammatory bowel diseases. Strain elastography (SE) is a US method for estimating tissue elasticity. This method is still not routinely used in clinical practice, although it is suggested by the EFSUMB Guidelines for the characterization of intestinal stenosis in Crohn's disease. The purpose of this Pictorial Essay is to confirm the feasibility of elastography in Crohn's disease in clinical practice by comparing elastography images with corresponding endoscopic or radiological images...

Video capsule endoscopy (VCE) has been of immense benefit in the diagnosis and management of gastrointestinal (GI) disorders since its introduction in 2001. However, it suffers from a number of well recognized deficiencies. Amongst these is the limited capability of white light imaging, which is restricted to analysis of the mucosal surface. Current capsule endoscopes are dependent on visual manifestation of disease and limited in regards to transmural imaging and detection of deeper pathology. Ultrasound capsule endoscopy (USCE) has the potential to overcome surface only imaging and provide transmural scans of the GI tract...

Over the recent years the non-invasive techniques for the evaluation of the small bowel have been playing a major role in the management of chronic intestinal diseases, such as inflammatory bowel diseases (IBD). The diagnostic performances of magnetic resonance imaging, computed tomography and ultrasound in the field of small bowel disorders, have been assessed and established for more than two decades. Newer sonographic techniques, such as strain elastography and shear wave elastography, have been put forward for the assessment of disease activity and characterization of IBD-related damage in the setting of Crohn's disease and other gastrointestinal disorders...

OBJECTIVES: Transversus abdominis plane (TAP) block for postoperative analgesia in laparoscopic cholecystectomy is usually given under ultrasound guidance. Laparoscopic-assisted TAP block has been suggested as an alternative to ultrasonogram (USG)-guided block as it is less time consuming and does not need extra equipments. This study was done to compare the efficacy of both the techniques. PATIENTS AND METHODS: We conducted a randomized controlled trial between October 2012 and June 2014 involving adult patients with symptomatic gall stone disease...

Immunodysregulation, Polyendocrinopathy, Enteropathy, X-linked (IPEX) syndrome is a rare, X-linked recessive disease that affects regulatory T cells (Tregs) resulting in diarrhea, enteropathy, eczema, and insulin-dependent diabetes mellitus. IPEX syndrome is caused by pathogenic alterations in FOXP3 located at Xp11.23. FOXP3 encodes a transcription factor that interacts with several partners, including NFAT and NF-κB, and is necessary for the proper cellular differentiation of Tregs. Although variable, the vast majority of IPEX syndrome patients have onset of disease during infancy with severe enteropathy...
