Abstract
Simple Summary Since small bowel adenocarcinoma may mimic a colorectal primary neoplasm histologically, it is pivotal to find biomarkers to discriminate these two biologically distinct neoplasms. The aim of our study was to evaluate the expression of special AT-rich sequence-binding protein 2 (SATB2), expressed in the vast majority of colorectal carcinomas, and other gastrointestinal phenotypic markers, such as cytokeratin 7, cytokeratin 20 and caudal type homeobox 2 (CDX2), in 100 small bowel adenocarcinomas. We identified 20 SATB2-positive small bowel adenocarcinomas, including nine sporadic cancers, seven celiac disease-associated cancers and four Crohn’s disease-associated small bowel adenocarcinomas. Six small bowel adenocarcinomas, including two cases associated with celiac disease and four sporadic, displayed a full colorectal carcinoma-like immunoprofile. Unlike SATB2, cytokeratin patterns stratified small bowel adenocarcinoma patient prognosis. The small bowel should be considered as one of the possible sites of origin in cancers of unknown primary, even when the neoplasm shows a colorectal carcinoma-like immunoprofile. Abstract Special AT-rich sequence-binding protein 2 (SATB2) is a transcription factor expressed by colonic cryptic epithelium and epithelial neoplasms of the lower gastrointestinal (GI) tract, as well as by small bowel adenocarcinomas (SBAs), though at a lower rate. Nevertheless, up to now, only small SBA series, often including a very limited number of Crohn’s disease-associated SBAs (CrD-SBAs) and celiac disease-associated SBAs (CD-SBA), have been investigated for SATB2 expression. We evaluated the expression of SATB2 and other GI phenotypic markers (cytokeratin (CK) 7 and CK20, caudal type homeobox 2 (CDX2) and alpha-methylacyl-CoA racemase (AMACR)), as well as mismatch repair (MMR) proteins, in 100 SBAs, encompassing 34 CrD-SBAs, 28 CD-SBAs and 38 sporadic cases (Spo-SBAs). Any mutual association and correlation with other clinico-pathologic features, including patient prognosis, were searched. Twenty (20%) SATB2-positive SBAs (4 CrD-SBAs, 7 CD-SBAs and 9 Spo-SBAs) were identified. The prevalence of SATB2 positivity was lower in CrD-SBA (12%) in comparison with both CD-SBAs (25%) and Spo-SBAs (24%). Interestingly, six SBAs (two CD-SBAs and four Spo-SBAs) displayed a full colorectal carcinoma (CRC)-like immunoprofile (CK7−/CK20+/CDX2+/AMACR+/SATB2+); none of them was a CrD-SBA. No association between SATB2 expression and MMR status was observed. Although SATB2-positive SBA patients showed a more favorable outcome in comparison with SATB2-negative ones, the difference did not reach statistical significance. When cancers were stratified according to CK7/CK20 expression patterns, we found that CK7−/CK20- SBAs were enriched with MMR-deficient cases (71%) and patients with CK7−/CK20− or CK7−/CK20+ SBAs had a significantly better survival rate compared to those with CK7+/CK20− or CK7+/CK20+ cancers (p = 0.002). To conclude, we identified a small (6%) subset of SBAs featuring a full CRC-like immunoprofile, representing a potential diagnostic pitfall in attempts to identify the site of origin of neoplasms of unknown primary site. In contrast with data on colorectal carcinoma, SATB2 expression is not associated with MMR status in SBAs. CK patterns influence patient survival, as CK7−/CK20− cancers show better prognosis, a behavior possibly due to the high rate of MMR-deficient SBAs within this subgroup.

Abstract
Pyloric type metaplasia (PYME) as evidence of chronic mucosal damage, is one of the main histopathological findings for diagnosing Crohn's Disease (CD) in terminal ileum biopsies, according to the latest guidelines but still frequently underdiagnosed in routine pathology. Foveolar metaplasia (FOME) changes in mucosa, another aspect of the chronic post -inflammatory Ulcer Associated Cell Lineage (UACL), have only been reported in a few cases. However, their clinical significance has not been investigated in depth except in pouchitis. The aim of this study was to investigate the importance of meticulous study of terminal ileum biopsies for the recognition of PYME/FOME as an adjunct finding helpful for the diagnosis of CD. In the present study, two experienced gastrointestinal pathologists, have reviewed 105 terminal ileum biopsies from 105 patients with CD, using a protocol of 15 sections on average per biopsy. In 21% (22/105) of cases PYME was recognized and in 4% (4/105) FOME was also present. PYME/FOME had not been detected in 83% of these cases in the original reports. FOME was also identified in terminal ileum biopsies, a feature not reported previously in CD. Conclusively, PYME/FOME can be easily missed in terminal ileum biopsies from patients with suspected or known CD unless a meticulous study of the histologic material is carried out combined with awareness of the pathologist about its importance.

Abstract
BACKGROUND Ulcerative colitis is an idiopathic inflammatory condition of the colon that may require surgical intervention including proctocolectomy and either ileal pouch-anal anastomosis or in the pediatric population, low ileorectal anastomosis (IRA). Often, subsequent physiologic alteration (or colonic metaplasia) occurs in the anastomosed small bowel that includes changes in mucin content, villous blunting, and increased expression of WNT5A, a marker of colonic crypt regeneration. We developed a rat low IRA model to assess and study the development of colonic metaplasia. MATERIALS AND METHODS We subjected male Sprague-Dawley rats (n = 17) to total colectomy and low IRA surgery and evaluated healing periodically by endoscopic evaluation. The ileum upstream of the anastomosis was assessed by hematoxylin and eosin staining, and the mucin content was measured by high iron diamine-Alcian blue staining. Wnt5a transcripts were quantified by reverse transcription and quantitative polymerase chain reaction at the 8-wk study end point. RESULTS Although no gross endoscopic evidence of inflammation was seen throughout the course of the study, colonic metaplasia in the small bowel was detected in 7 out of 10 (70%) rats at the study end point. In rats with colonic metaplasia, enhanced expression of Wnt5a was evident at the study end point compared to levels in the terminal ileum at the time of surgery. CONCLUSIONS Within 4-8 wk, the majority of rats subjected to IRA developed colonic metaplasia defined by villous blunting, changes in mucin content, and increased expression of Wnt5a. This model provides a method to study small bowel colonic metaplasia.

Abstract
BACKGROUND AND PURPOSE Pouchitis is the most common long-term complication of restorative proctocolectomy with ileal pouch-anal anastomosis. We investigated alterations in the expression of microRNAs, noncoding RNAs that act as potent negative regulators of gene expression, in pouchitis. METHODS The subjects of this study were 16 patients with diagnosed pouchitis and 48 patients without pouchitis after restorative proctocolectomy, performed for ulcerative colitis. Total RNA was extracted from biopsies and microRNAs were quantified using a real-time polymerase chain reaction. RESULTS The expression of microRNA 21 and 223 was higher, whereas that of microRNA 192 and 196a was lower, in the inflamed mucosa from the pouchitis patients than in the mucosa from the non-pouchitis patients. The levels of 14 microRNAs were significantly lower in the mucosa from the pouchitis patients, than in the non-inflamed proximal ileal mucosal samples. The expression of microRNA 192 was remarkably reduced in pouchitis. A significant negative correlation was found between microRNA 192 and interleukin 17 receptor A mRNA levels. CONCLUSIONS Significant alteration in miRNA expression in line with inflammatory bowel disease was evident in the mucosa from the pouchitis patients. Interleukin 17 receptor A may be involved in the pathogenesis of pouchitis through the downregulation of microRNA 192.
