In patients with haematological malignancies, the bowel remains the main source of Escherichia coli bloodstream infections. We present the clinical example of recurrent bowel-blood translocations of E. coli with the unique virulence characteristics in a 55-year-old male with the diagnosis of acute myeloid leukaemia. The virulent factors profile of examined strains confirmed that the co-existence of genes papC, sfa, usp and cnf1, encoding virulence factors, predisposes E. coli to translocation from the gastrointestinal tract to the vascular bed...

Little is known about the link between gastric microbiota and the epidemiology of gastric cancer. In order to determine the epidemiologic and clinical relevance of gastric microbiota, we used 16S ribosomal RNA gene sequencing analysis to characterize the composition and structure of the gastric microbial community of 80 paired samples (non-malignant and matched tumor tissues) from gastric cardia adenocarcinoma (GCA) patients in Shanxi, China. We also used PICRUSt to predict microbial functional profiles. Compared to patients without family history of upper gastrointestinal (UGI) cancer in the non-malignant gastric tissue microbiota, patients with family history of UGI cancer had higher Helicobacter pylori (Hp) relative abundance (median: 0...

Objective: To investigate the characteristics of the rectal potentially malignant nodules in female by digital rectal examination (DRE). Methods: Retrospectively, we collected the medical information and follow-up of rectal nodules cases diagnosed as benign by DRE during the health check-up in our hospital from Jan 2002 to Dec 2015. All nodules were recorded position, size, shape, hardness and mobility. Statistical analysis was performed to select the potentially malignant cases of postoperative pathological diagnosis and disappeared nodules followed up by DRE...

Interpretation of next-generation sequencing (NGS) of tumor tissue in patients with advanced Urinary Tract Cancer (UTC) is performed to guide treatment selection but may reveal pathogenic variants with germline implications. We identified three patients with UTC with unexpected germline DNA repair gene mutations. Specific testing for these was prompted by the detection of these mutations by tumor NGS. All three patients were nonsmokers with a strong family history of cancer. Two patients had upper tract UTC with age at diagnosis in the 40 s...

BACKGROUND AND AIMS: Self-expandable metallic stent insertion has been a mainstream treatment for relieving the obstructive symptoms of malignant gastric outlet obstruction (MGOO), a late-stage complication of gastrointestinal malignancies. This study aims to investigate the predictive value of stent expansion rates in clinical outcomes in patients with MGOO. METHODS: Eighty-seven patients with inoperable MGOO receiving metallic stents were reviewed retrospectively from April 2010 to December 2014...

Poly(ADP-ribose) polymerase-1 (PARP-1) is a nuclear enzyme that plays a critical role in diverse cellular functions, such as DNA damage detection and repair, transcriptional regulation and cell death. Furthermore, PARP-1 has emerged as a key player in the pathogenesis of multiple inflammatory diseases and has become a promising target for the treatment of cardiovascular disorders, neurodegenerative diseases and cancer. An increasing body of evidence has linked alterations in the expression levels of PARP-1, enzymatic activity and presence of polymorphism to gastrointestinal malignancies, including oesophageal, gastric, pancreas, liver and colorectal cancers...

Liver transplant is now an acceptable and effective treatment for specific nonhepatocellular malignancies. Worldwide, hilar cholangiocarcinoma accounts for 3% of all primary gastrointestinal malignancies and for 10% of primary hepatobiliary malignancies. For patients who have early-stage, unresectable cholangiocarcinoma, liver transplant preceded by neoadjuvant radiotherapy can result in tumor-free margins, accomplish a radical resection, and treat the underlying primary sclerosing cholangitis when present...

Purpose To analyze the cost effectiveness of the American Society for Gastrointestinal Endoscopy (ASGE) risk stratification guidelines versus magnetic resonance (MR) cholangiopancreatography-based treatment of patients with possible choledocholithiasis. Materials and Methods A decision-analytic model was constructed to compare cost and effectiveness of three diagnostic strategies for gallstone disease with possible choledocholithiasis: noncontrast MR cholangiopancreatography, contrast material-enhanced MR imaging/MR cholangiopancreatography, and ASGE risk stratification guidelines for diagnostic evaluation recommending endoscopy (high risk), MR cholangiopancreatography (intermediate risk), or no test (low risk)...

The occurrence of multiple primary melanomas in a single individual is rare. Most commonly, malignant melanocytic lesions subsequent to the initial diagnosis of melanoma are secondary cutaneous metastases. We report a patient with gastrointestinal bleeding from gastric metastasis of cutaneous melanoma. During clinical evaluation and staging, we discovered a brain metastasis associated with 3 synchronous primary cutaneous melanomas. We suggest the research on the mutation in the cyclin-dependent kinase inhibitor 2A (CDKN2A) (INK4a) in such cases...

Brunner's gland hamartoma, also called hyperplasia, adenoma, and Brunneroma, is an extremely rare benign proliferative lesion of Brunner's glands in the duodenum. While being mostly small and asymptomatic, they can result in gastrointestinal bleeding and obstruction. We report the case of a 54-year-old man presenting with melena and severe anemia requiring blood transfusion. CT scans showed a large mass of 8 cm in diameter, presumably arising in the duodenum. Endoscopic biopsies were not conclusive. As we were unable to determine the nature of the mass preoperatively and due to the severe symptoms, its size, and the uncertain malignant potential, a classic Whipple procedure was performed...

INTRODUCTION: Inflammatory bowel disease is a chronic condition of the gastrointestinal tract, comprising mainly Crohn disease (CD) and ulcerative colitis (UC). Both of them are frequently encountered in children, being multifactorial conditions, with an unclear etiology. PATIENTS CONCERNS: We present 4 cases of inflammatory bowel disease (IBD) in children in order to underline the variable evolution depending on the patient's particularities. DIAGNOSIS, INTERVENTIONS AND OUTCOMES: The first case, a 13-year-old male patient, with a history of Henoch-Schonlein purpura, was admitted for rectal bleeding and weight loss, with normal laboratory parameters...

BACKGROUND: Anal squamous cell carcinoma (ASCC) is rare, accounting for only 1% of gastrointestinal malignancies. We sought to better understand management strategies for ASCC in the setting of Crohn's disease (CD). METHODS: A retrospective chart review from 2001 to 2016 was conducted using ICD-9/10 codes for CD (555.9/K50) and ASCC (154.3/C44.520). Adult patients with a diagnosis of CD at the time of ASCC diagnosis were included. RESULTS: Seven patients (five female) were included with a median age of 50 years...

Immune checkpoint inhibitors, including the anti-CTLA-4 antibody ipilimumab, the anti-PD-1 antibodies nivolumab and pembrolizumab, and the anti-PD-L1 antibody atezolizumab had produced long-lasting tumor responses in several malignancies. Immune-related Adverse Events(irAEs)which are different from adverse events of conventional chemotherapy and molecular targeted therapy, occur as a consequence of impaired self-tolerance from loss of T-cell inhibition. The main irAEs of immune checkpoint inhibitors include dermatological, gastrointestinal, pulmonary, hepatic, endocrine, renal toxicities...

CNS metastases have long been recognized as a common and late complication of systemic malignancies. They represent the most common tumor of the brain. As outcomes and overall survival improve with better tolerated and more durable responses from therapies for systemic cancers, the incidence and prevalence of brain metastases is likely to increase. Among the most common systemic cancers leading to brain metastases include lung, melanoma, breast (triple-negative histology) and renal cell cancers. To date, there has been infrequent involvement of gastrointestinal and gynecologic malignancies; however, this may also change, reflecting improvement in overall survival and therapeutic regimens...

AIM: To assess nutritional recovery, particularly regarding feeding jejunostomy tube (FJT) utilization, following upper gastrointestinal resection for malignancy. METHODS: A retrospective review was performed of a prospectively-maintained database of adult patients who underwent esophagectomy or gastrectomy (subtotal or total) for cancer with curative intent, from January 2001 to June 2014. Patient demographics, the approach to esophagectomy, the extent of gastrectomy, FJT placement and utilization at discharge, administration of parenteral nutrition (PN), and complications were evaluated...

Soft-tissue sarcomas are a diverse group of rare mesenchymal malignancies that can arise at any location in the body and affect all age groups. These sarcomas are most common in the extremities, trunk wall, retroperitoneum, and head and neck. In the adult population, soft-tissue sarcomas arising in the abdomen and pelvis are often large masses at the time of diagnosis because they are usually clinically silent or cause vague or mild symptoms until they invade or compress vital organs. In contrast, soft-tissue sarcomas arising from the abdominal wall come to clinical attention earlier in the course of disease because they cause a palpable mass, abdominal wall deformity, or pain that is more clinically apparent...

Heterotopic pancreas is a congenital anomaly in which pancreatic tissue is anatomically separate from the main gland. The most common locations of this displacement include the upper gastrointestinal tract-specifically, the stomach, duodenum, and proximal jejunum. Less common sites are the esophagus, ileum, Meckel diverticulum, biliary tree, mesentery, and spleen. Uncomplicated heterotopic pancreas is typically asymptomatic, with the lesion being discovered incidentally during an unrelated surgery, during an imaging examination, or at autopsy...

Lower gastrointestinal (GI) neuroendocrine neoplasms (NENs) of the colon and rectum are uncommon and not traditionally associated with hereditary GI cancer syndromes. However, with widespread implementation of colorectal cancer screening programs, lower GI NENs are being identified with increasing frequency. We report the first case series of six patients with lower GI NENs who were diagnosed with hereditary GI cancer syndromes by germline testing. Two patients presented with poorly differentiated rectal neuroendocrine carcinoma (NECs) with colonic polyposis and were found to have Familial Adenomatous Polyposis and MYH-Associated Polyposis, respectively...

Saprochaete capitata (formerly known as Blastoschizomyces capitatus, Trichosporon capitatum, Geotrichum capitatum) is a rare but emerging yeast-like fungus. It is commonly found in environmental sources and can be isolated from skin, gastrointestinal system and respiratory tract of healthy individuals as well. It mainly infects patients with hematological malignancies such as acute myeloid leukemia (AML), especially in the presence of neutropenia; and mortality rates are high in those patients. Although the data about the in vitro antifungal susceptibility are limited, it is being reported that amphotericin B and voriconazole are more effective on S...
