AIMS: Gastric heterotopia (GH) has been described throughout the gastrointestinal tract. However, the colorectal region is an extremely rare location for it. We describe the clinicopathologic features of GH of the colon, rectum, and anus. METHODS AND RESULTS: We identified 33 cases in 20 males and 13 females (median age 54 years; range, 4 months to 73 years). Sites included the rectum (N=26), anus (N=4), ileocecal junction (N=1), ascending colon (N=1) and descending colon (N=1)...

The population of cancer survivors with prior cancer is rapidly growing. Whether a prior cancer diagnosis interferes with outcome is unknown. We conducted a pan-cancer analysis to determine the impact of prior cancer history for patients newly diagnosed with cancer. We identified 20 types of primary solid tumors between 2004 to 2008 in the Surveillance, Epidemiology, and End Results (SEER) database. Demographic and clinicopathologic variables were compared by chi-squared test and t-test as appropriate. The propensity score-adjusted Kaplan-Meier method and Cox proportional hazards models were used to evaluate the impact of prior cancer on overall survival (OS)...

BACKGROUND: Zymogen granule protein 16 (ZG16) is one of the most significantly down-regulated genes in colorectal cancer (CRC) tissues. This study aimed to further evaluate its expression changes and investigate its association with molecular and clinicopathological characteristics of CRC. METHODS: We applied quantitative RT-PCR to determine expression difference between tumor and matched normal tissues from 23 CRC patients. To further validate the down-regulation in tumor tissues, we performed immunohistochemistry (IHC) analysis in 40 paraffin-embedded normal-tumor pairs and 22 colon tissues with a variety of diseases...

BACKGROUND & AIMS: Colorectal tumors with mutations in BRAF and microsatellite stability (MSS) have been associated with adverse outcomes of patients. Combined tests for microsatellite instability (MSI-H) and BRAF mutations might therefore be used in risk assessment, particularly for patients with stage II tumors. We investigate the stage-specific prognostic value of combined testing for MSI-H and BRAF for patients with colorectal cancer (CRC). METHODS: We performed a retrospective analysis of colorectal tumor samples collected from 1995 patients at 22 hospitals in Germany, between 2003 and 2010...

Abdominal symptoms are common in patients with lupus nephritis and are often attributed to drugs or uremia per se. Lupus mesenteric vasculitis (LMV) or lupus enteritis is a rare entity reported in patients with active systemic lupus erythematosus. It usually occurs in patients with a long-standing history of lupus with high disease activity. Usually, small bowel is predominantly affected. The stomach and rectum are spared in view of significant collateral circulation. Here, we describe an 18-year-old boy who presented with nephrotic syndrome without any extrarenal features of lupus...

BACKGROUND: Recovery after colonic surgery is invariably delayed by disturbed gut motility. It is commonly assumed that colonic motility becomes quiescent after surgery, but this hypothesis has not been evaluated rigorously. This study quantified colonic motility through the early postoperative period using high-resolution colonic manometry. METHODS: Fibre-optic colonic manometry was performed continuously before, during and after surgery in the left colon and rectum of patients undergoing right hemicolectomy, and in healthy controls...

Characterizing the transmitted/founder (T/F) viruses of multi-variant SIV infection may shed new light on the understanding of mucosal transmission. We intrarectally inoculated six Chinese rhesus macaques with a single high dose of SIVmac251 (3.1 × 104 TCID50 ) and obtained 985 full-length env sequences from multiple tissues at 6 and 10 days post-infection by single genome amplification (SGA). All 6 monkeys were infected with a range of 2 to 8 T/F viruses and the dominant variants from the inoculum were still dominant in different tissues from each monkey...

The patient was a 57-year-old woman. Preclinical examination of malignant lymphoma revealed 0-I sp type of early rectal cancer in the upper rectum, 20 cm from the anal margin. Endoscopic mucosal resection was performed and positive deep margins were pathologically diagnosed. Additional intestinal resection with lymph node dissection was deemed necessary, but ABVD therapy was initiated because the clinical stage of the malignant lymphoma was Stage III b or higher. Two months after detecting elevated CEA, S8 liver metastasis was pointed out, and examination of weakness of the right upper limb revealed nodular, multifocal brain metastasis...

Background: In May 2015, we noticed an increase in carbapenem-resistant Acinetobacter baumannii (CRAB) infections in the Medical Intensive Care Unit (MICU). To investigate this, we studied the extent of environmental contamination and subsequent onward clonal transmission of CRAB. Methods: We conducted a one-day point prevalence screening (PPS) of the patients and environment in the MICU. We screened patients using endotracheal tube aspirates and swabs from nares, axillae, groin, rectum, wounds, and exit sites of drains...

The guideline for the treatment of rectal prolapse recommends that surgeons select appropriate surgical procedures individually based on each patient's overall status. However, in cases of irreducible or incarcerated rectal prolapse, surgical options are quite limited. Here we present a case of an elderly woman with massive chronic irreducible rectal prolapse. An 87-year-old woman presented to our hospital with a complaint of massive rectal prolapse. The prolapsed rectum was over 20 cm long, and completely irreducible...

Colorectal cancer (CRC) is the second most frequent and fatal cancer in Western countries. Understanding its biology with different incidence along the colon and rectum, genetic profile and how these factors contribute to local/distant progression, has been hampered by the lack of a suitable CRC model. We report a reproducible model, using human CRC cell lines (CL) (WiDr, LS1034, C2BBe1) injected (1 × 107 cells/animal) in RNU rats (n = 55) which underwent cecostomy and descending colostomy with mucosal-cutaneous fistula of the sigmoid colon...

Trypanosoma rangeli is a protozoan parasite that infects mammals and triatomines, causing different levels of pathogenicity in its invertebrate vectors, particularly those from the genus Rhodnius. We have recently shown that temperature can modulate T. rangeli growth during in vitro culture, as well as its in vivo pathogenicity to R. prolixus. In the present study, we investigated colonization of R. prolixus by T. rangeli and assessed the role of temperature and vector nutrition on parasite development and multiplication...
