BackgroundLactobacilli 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. There are sporadic reported cases of infections related to lactobacilli containing probiotics.Case presentationIn this paper we discuss a case of an 82 year old female with liver abscess and bacteremia from lactobacillus after using probiotics containing lactobacilli in the course of her treatment of Clostridium difficile colitis. The Lactobacillus strain identification was not performed and therefore, both commensal microbiota and the probiotic product should be considered as possible sources of the strain.ConclusionLactobacilli can lead to bacteremia and liver abscesses in some susceptible persons and greater awareness of this potential side effect is warranted with the increasing use of probiotics containing lactobacilli.
Endoscopic findings of the colon were different; the first case demonstrated a reddened colonic fold without an obvious mass and the other had an ulcerated friable mass. Both of the tumors had positive immunohistochemical stains for CD31 and CD34 (one was also positive for CD117). Surgery was not performed in either case. Treatment included chemotherapy with imatinib for the first patient and paclitaxel for the second. Prognosis for this tumor is generally poor; in our cases, one patient was still alive after 5 months of follow-up and the other died within 2 months of diagnosis. After presenting our cases, we reviewed the current literature on angiosarcoma of the colon.
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. Results: A total of 374 patients (147 rivaroxaban vs. 227 dabigatran) were identified. GI bleeding occurred in 5.3% in the dabigatran when compared to 4.8% in the rivaroxaban group (p = 0.8215). Multivariate analysis showed that the odds of GI bleeding while on dabigatran for ≤40 days when compared to ≥40 days was 8.3 (p < 0.0001). In the rivaroxaban group, patients who were on the drug for ≤40 days had a higher incidence of bleeding when compared to those >40 days (OR = 2.8, p = 0.023). Concomitant use of antiplatelets (single or dual) or non-steroidal anti-inflammatory drugs was not associated with increased bleeding in the dabigatran group; however, the use of dual antiplatelet agents with rivaroxaban was associated with an increased risk of GI bleeding (OR = 7.4, p = 0.0378). Prior GI bleeding had a higher risk of bleeding in the rivaroxaban group (OR = 15.5, p = 0.0002). Conclusion: Dabigatran was not associated with a higher incidence of GI bleeding. Both drugs had a higher bleeding risk in the first 40 days.
IC is majorly occurred in elderly with a female predominance. Cardiovascular disease and its associated risk factors are the most common comorbidities. Left colon is the most affected location of the disease and the overall mortality rate was 4.2%. Physicians should make every effort to identify these patients, especially those with high risks.
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). Along with hepatoportal venous gas (HPVG), it was considered as an ominous radiological sign and warranted an emergent surgical exploration; however, with widespread use of computerized tomographic (CT) scan, an increasing number of benign causes of GE and HPVG have been reported in the literature, where patients can be managed by noninvasive and conservative measures. We hereby describe a case where recurrent episodes of vomiting led to development of GE and HPVG and the patient was managed successfully by conservative measures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
