Liver abscess and bacteremia caused by lactobacillus: role of probiotics? Case report and review of the literature.

Background: Lactobacilli are non-spore forming, lactic acid producing, gram-positive rods. They are a part of the normal gastrointestinal and genitourinary microbiota and have rarely been reported to be the cause of infections. Lactobacilli species are considered non-pathogenic organisms and have been used as probiotics to prevent antibiotic associated diarrhea.

Comparison of Ischemic Colitis in the Young and the Elderly.

Background: Ischemic colitis is traditionally known as a disease of the elderly; however, its recognition among the young recently has increased. The aim of this study was to illustrate the features of ischemic colitis in a younger population.

Methods: Medical records of patients with ischemic colitis from January 2007 to January 2013 were reviewed.

Risk of Gastrointestinal Bleeding with Rivaroxaban: A Comparative Study with Warfarin.

Introduction. The risk of gastrointestinal (GI) bleeding with rivaroxaban has not been studied extensively. The aim of our study was to assess this risk in comparison to warfarin.

Basaloid Squamous Cell Carcinoma of the Sigmoid Colon.

Basaloid squamous cell carcinoma (BSCC) of the colon is rarely found proximal to the anal canal. We report a case of an 81-year-old woman who was diagnosed with squamous cell carcinoma (SCC) of the lung without metastasis and BSCC of the sigmoid with differing histologic findings suggesting that these tumors were separate primary neoplasms. SCC of the colon has a dismal prognosis.

Gastrointestinal bleeding with dabigatran, a comparative study with warfarin: a multicenter experience.

Background/aims: The risk of gastrointestinal (GI) bleeding with dabigatran when compared to warfarin has been controversial in the literature. The aim of our study was to assess this risk with the use of dabigatran.

Methods: We examined the medical records of patients who were started on dabigatran or warfarin from October 2010 to October 2012.

Vomiting-induced gastric emphysema and hepatoportal venous gas: a case report and review of the literature.

Gastric pneumatosis is the presence of air within the wall of the stomach. It represents a spectrum of conditions ranging from benign disease to septic shock and death. Etiopathologically, it can be classified into emphysematous gastritis or gastric emphysema (GE).

Radiation therapy-induced aortoesophageal fistula: a case report and review of literature.

Aortoesophageal fistula (AEF) is a rare cause of massive upper gastrointestinal hemorrhage. Thoracic aortic aneurysm, esophageal foreign body, esophageal cancer and post-surgical complications are common causes of AEF; however, AEF induced by radiation therapy is a rare phenomenon and seldom described in the literature. It is a catastrophic condition which requires rapid implementation of resuscitative measures, broad-spectrum antibiotics and surgical or endovascular intervention.

Risk of gastrointestinal bleeding with dabigatran: a head-to-head comparative study with rivaroxaban.

Introduction: The risk of gastrointestinal (GI) bleeding of dabigatran and rivaroxaban is relatively unexplored. The aim of our study was to compare this risk in both drugs.

Methods: We examined the medical records of patients on either dabigatran or rivaroxaban from October 2010 to April 2013 in two hospitals.

Ischemic colitis: A forgotten entity. Results of a retrospective study in 118 patients.

Objective: The aim of our study was to document our 6-year experiences in identifying the clinical characteristics, laboratory findings, risk factors and the outcomes of patients with ischemic colitis (IC) in a community hospital setting.

Methods: The medical records of patients who were diagnosed with IC from 2007 to 2013 in two community hospitals were retrospectively reviewed. Their clinical characteristics, laboratory results, radiological, endoscopic and histological evidence, anatomic location of the lesion, comorbidities, concomitant use of drugs, and so on, were collected.

Is CT Angiogram of the Abdominal Vessels Needed following the Diagnosis of Ischemic Colitis? A Multicenter Community Study.

Background. CT angiogram is frequently obtained after diagnosis of ischemic colitis (IC). Aims.

Risk factors of recurrent ischemic colitis: a multicenter retrospective study.

Background/aims: Recurrence of ischemic colitis (IC) has not been studied extensively. The aim of this study was to investigate the characteristics of recurrent IC in the community setting and to identify any risk factors.

Methods: We conducted a retrospective study in two community hospitals.

Metastatic infiltrating ductal carcinoma of the breast to the colon: a case report and literature review.

True metastatic involvement of the colon is rare. Colonic metastases occur most commonly secondary to peritoneal metastases from intra-abdominal malignancies. Breast cancer is the most common malignancy that metastasizes hematogenously to the colon.

Klippel-Trenaunay Syndrome Causing Life-Threatening GI Bleeding: A Case Report and Review of the Literature.

Klippel-Trenaunay syndrome (KTS) is a rare congenital syndrome of vascular malformations and soft tissue and bone hypertrophy. Vascular malformations can affect multiple organ systems. Involvement of the gastrointestinal (GI) tract is uncommon in KTS, but it can be a source of life-threatening bleeding.

What's new about inflammatory bowel diseases in Ischemic colitis induced by the newly reformulated multicomponent weight-loss supplement Hydroxycut(®).

Ischemic colitis accounts for 6%-18% of causes of acute lower gastrointestinal bleeding. It is more often multifactorial and more common in elderly. Drugs are considered important causative agents of this disease with different mechanisms.

Clinical and endoscopic features of angiosarcoma of the colon: two case reports and a review of the literature.

Background: Angiosarcoma of the gastrointestinal tract is an extremely rare tumor. We present two cases of angiosarcoma of the colon. One patient developed syncope and anemia and the other had rectal bleeding.

Lubiprostone induced ischemic colitis.

Ischemic colitis accounts for 6%-18% of the causes of acute lower gastrointestinal bleeding. It is often multifactorial and more commonly encountered in the elderly. Several medications have been implicated in the development of colonic ischemia.

T-cell non-Hodgkin's lymphomas reported to the FDA AERS with tumor necrosis factor-alpha (TNF-α) inhibitors: results of the REFURBISH study.

Objectives: The risk of non-Hodgkin's lymphoma (NHL) with tumor necrosis factor alpha (TNF-α) inhibitors is unclear, whether related to concomitant thiopurines usage or due to the underlying inflammatory disease. We sought to review all cases of T-cell NHL reported to the Food and Drug Administration (FDA) in patients receiving TNF-α inhibitors for all approved indications and examine the risk of T-cell NHL with TNF-α inhibitors in comparison with the use of thiopurines in inflammatory bowel disease (IBD).

Methods: The FDA Adverse Event Reporting System (AERS) was queried for all lymphomas following treatment with the following TNF-α inhibitors: infliximab, adalimumab, certolizumab, etanercept, and their trade names.
