REVIEW
A Fabisiak, J Fichna
In this mini-review, we focus on the potential of the endocannabinoid system as a target for novel therapies to treat gastrointestinal (GI) inflammation. We discuss the organization of the endocannabinoid signaling and present possible pharmacological sites in the endocannabinoid system. We also refer to recent clinical findings in the field. Finally, we point at the potential use of cannabinoids at low, non-psychoactive doses to counteract non-inflammatory pathological events in the GI tract, like chemotherapy-induced diarrhea, as evidenced by Abalo et al...

Bats belong to the order Chiroptera that represents the second largest order of mammals with more than 1200 species and an almost global distribution. Environmental changes and deforestation have severely influenced many ecosystems, intensifying the contact between wildlife and humans. In recent years, bats have been found to harbor a number of different viruses with zoonotic potential, as well as a great diversity of astroviruses, for which the question of zoonotic potential remains unanswered to date. Human astroviruses have been identified as the causative agent for diarrhea in children and immunocompromised patients...

Declan J Bolton, Lucy J Robertson
Human infections with foodborne pathogenic organisms are relatively well described in terms of their overt physical symptoms, such as diarrhea, abdominal cramps, vomiting, fever, and associated sequelae. Indeed, some of these are key for diagnosis and treatment, although it should be noted that, for some foodborne pathogens, the physical symptoms might be more diffuse, particularly those associated with some of the foodborne parasites. In contrast, the impact of these pathogens on mental health is less well described, and symptoms such as depression, anxiety, and general malaise are usually ignored when foodborne infections are recorded...

INTRODUCTION: Idiopathic cyclic edema (ICE) is a rare cause of edema. To date, there is no standard of care. The physiopathology of ICE could be explained by an impairment of capillary permeability. In 1995, a study demonstrated the efficacy of metformin on symptoms and capillary permeability. We evaluated ICE-patients who were treated with metformin in our department. METHODS: We retrospectively included patients diagnosed for ICE between January 1997 and October 2013...

BACKGROUND: Since 1984, WHO has endorsed drug treatment to reduce Schistosoma infection and its consequent morbidity. Cross-sectional studies suggest pre-treatment correlation between infection intensity and risk for Schistosoma-related pathology. However, evidence also suggests that post-treatment reduction in intensity may not reverse morbidity because some morbidities occur at all levels of infection, and some reflect permanent tissue damage. The aim of this project was to systematically review evidence on drug-based control of schistosomiasis and to develop a quantitative estimate of the impact of post-treatment reductions in infection intensity on prevalence of infection-associated morbidity...

Hydrocarbons are a wide-ranging group of flammable chemicals and are often used in suicide attempts either by ingestion or as accelerant in self-immolation. In this case study, we present a 37-year-old female who suffered 6% TBSA partial-thickness burns to her perineum and buttocks, which she claims resulted from diarrhea after ingesting a bottle of lighter fluid. The patient underwent decontamination and medical treatment for her burns and during her inpatient stay, it became apparent that the burns were more likely sustained from an intentional rectal administration of lighter fluid...

Although a relatively recently emerged virus, identified only in 2004 as a separate species of avian astrovirus, chicken astrovirus (CAstV) has been associated with poor growth of broiler flocks, enteritis and diarrhea and is a candidate pathogen in cases of runting stunting syndrome. More recently CAstV has been implicated in cases of two other diseases of broilers as the sole etiological agent, namely severe kidney disease of young broilers with visceral gout and the "White Chicks" hatchery disease. Examination of the strains of CAstV associated with the two latter diseases reveals they are closely related genetically...

Klebsiella pneumoniae (K.pneumoniae) is a known cause of pyogenic liver abscess (PLA) in the absence of hepatobiliary disease. In settings of hepatic infection, it has also been known to cause disseminated infections including meningitis and endopthalmitis. Several groups of patients are particularly susceptible to infection, including patients with diabetes mellitus, those from Southeast Asia and those with the preexisting hepatobiliary disease. We present a case of K.pneumoniae PLA with bacteremia. A 39-year-old Vietnamese male with no previous medical history who presented with complaints of abdominal pain, nausea, vomiting, diarrhea and fever...

Giardiasis is the most common intestinal parasitic infection in the United States. The organism elicits no, or minimal, inflammatory changes in duodenal biopsy samples, so it can be easily overlooked. We performed this study to determine whether Giardia could be isolated from the formalin fixative of biopsy samples, and to evaluate the value of fluid analysis in the assessment for potential infection. We prospectively evaluated duodenal biopsy samples from 92 patients with a clinical suspicion of giardiasis or symptoms compatible with that diagnosis (ie, diarrhea, bloating, or abdominal pain) Biopsy samples were routinely processed and stained with hematoxylin and eosin...

BACKGROUND: The benefits of transarterial chemoembolization plus sorafenib (TACE-S) in hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT) remain controversial. We compared the effectiveness and safety of TACE-S and TACE for HCC with PVTT. METHODS: The Cochrane Library, PubMed, EMBASE, Chinese National Knowledge Infrastructure, VIP, Wan Fang, and Sino Med databases were systematically searched for studies of HCC with PVTT treated using TACE-S. Two authors independently extracted study outcomes, including overall survival (OS), time to progression (TTP), objective response (tumor response) and adverse events (AEs)...

Diarrhea is a feature of several chronic intestinal disorders that are associated with increased delivery of bile acids into the colon. Although the prevalence of bile acid diarrhea is high, affecting approximately 1% of the adult population, current therapies often are unsatisfactory. By virtue of its capacity to inhibit colonic epithelial fluid secretion and to down-regulate hepatic bile acid synthesis through induction of the ileal fibroblast growth factor 19 release, the nuclear bile acid receptor, farnesoid X receptor, represents a promising target for the development of new therapeutic approaches...
