Ulcers are a frequent cause of dermatologic consultation, and most correspond to leg ulcers. Major advances in the treatment of ulcers have occurred in recent years as a result of research that has led to new concepts such as the consideration of the chronic ulcer as an inflammatory process involving ...

Blastocystis hominis is an enteric parasite which has long been considered as an innocuous commensal living in the intestinal tract. Our research was to explore the role of B. hominis in refractory ulcerative colitis. Our department admitted 122 cases of ulcerative colitis patients. In these patients, there were 73 cases ...

Chronic granulomatous disease (CGD) is a genetic disorder of the phagocyte NADPH oxidase, which predisposes patients to infections and inflammatory complications, including severe colitis. Management of CGD colitis is a challenge because standard immunosuppressive therapy increases the risk of infection in already immunocompromised hosts. We report the use of infliximab ...

BACKGROUND: Debate persists regarding the role of Desulfovibrio subspecies in ulcerative colitis. Combined microscopic and molecular techniques enable this issue to be investigated by allowing precise enumeration of specific bacterial species within the colonic mucous gel. The aim of this study was to combine laser capture microdissection and quantitative polymerase ...

Substantial data show that infection with helminth parasites ameliorates colitis; however, oxazolone-induced colitis is exaggerated in mice infected with the tapeworm, Hymenolepis diminuta. We tested the hypothesis that the IL-5 response to helminth infection enhances the severity of oxazolone-induced colitis. Mice were infected with H. diminuta and 8 days later ...

A recent publication in the Journal of Proteome Research applied metabolic profiling ("metabonomics") to ulcerative colitis; several different biosamples were investigated ( J. Proteome Res. 2010 , 9 , 954 - 962 ). Comparing urinary profiles, no differences were found between cases and controls; in a previously published study ( ...

The ability of intestinal helminths to manipulate the immune system of their host towards a Th2 response has been proposed to modulate auto-immune and allergic diseases. This initial study investigated the anti-inflammatory potential of S. mansoni and soluble egg antigen (SEA) in a murine model of colitis. Colitis was induced ...

Infective colitis can be a cause of massive lower gastrointestinal bleeding requiring acute surgical intervention. Causative organisms include entamoeba and histoplasma species. However, concurrent colonic infection with both these organisms is very rare, and the in vivo consequences are not known. A 58-year-old male presented initially to the physicians with ...

Inflammatory bowel disease (IBD) is increasing in many parts of the Asia-Pacific region. There is a need to improve the awareness of IBD and develop diagnostic and management recommendations relevant to the region. This evidence-based consensus focuses on the definition, epidemiology and management of ulcerative colitis (UC) in Asia. A ...

Klebsiella oxytoca was recently described as the causative organism for antibiotic-associated hemorrhagic colitis (AAHC). It is currently not known if this novel gastrointestinal infection exists in children. AAHC is usually preceded by antibiotic treatment with penicillins, which are frequently prescribed for pediatric patients. In contrast to colitis caused by Clostridium ...

A 71-year-old man was diagnosed with ulcerative colitis (UC) complicated by bacterial infections, and his active disease proved difficult to treat with steroid therapy or antibiotics. Although the patient's UC failed to respond to several types of induction therapy, his condition finally improved when treated using Bifidobacterium. Probiotics could be ...

PRACTICE PEARL This study demonstrates the efficacy and safety of another 5-ASA agent in a delayed response form embedded in a hydrophobic-hydrophilic structure. Original Article Kamm MA, Sandborn WJ, Gassull M, et al. Once-daily, high-concentration MMX mesalamine in active ulcerative colitis. Gastroenterology. 2007;132(1):66-75.

Apriso (Salix) is a new formulation of mesalamine (5-aminosalicylic acid; 5-ASA) approved by the FDA for maintenance of remission in mild to moderate ulcerative colitis (UC). Mesalamine is a locally acting antiinflammatory agent that is widely used both to maintain and induce remission in inflammatory bowel disease. Various mesalamine formulations ...

BACKGROUND: The aetiology of ulcerative colitis is uncertain but may relate to environmental factors in genetically predisposed individuals. Sulphate-reducing bacteria (SRB) have been implicated through the harmful effects of hydrogen sulphide, a by-product of their respiration. Hydrogen sulphide is freely permeable to cell membranes and inhibits butyrate. This review examines ...

Enterobius vermicularis is the most common helminthic infection in the US. It is usually considered an innocuous parasite that at the most causes perianal itching. We report a case of an 84-year-old female patient from an assisted living facility who presented with symptoms of colitis for 2 months. On detailed ...

The presence of VCA IgG in the absence of VCA IgM and EBNA-1 IgG antibodies makes classifying EBV infection more difficult as this serological picture can be seen in the case of past infection with EBNA-1 IgG loss or non-appearance, or acute infections with the early disappearance or delayed onset ...

HCV infection provides a classic example of the phenomenon of quasispecies. Because several lines of investigation support the contribution of quasispecies to HCV's capacity to maintain a persistent infection, adequate characterization of the quasispecies is important. The hypervariable region 1 (HVR1) of the E2 glycoprotein has been particularly well studied ...

OBJECTIVE: The aim of the study was to investigate the association between serum lipids and periodontal infection and the role of serum lipids in the association between body weight and periodontal infection. MATERIAL AND METHODS: The Health 2000 Health Examination Survey, which included 8028 subjects aged 30 or older living ...

Infection levels of eastern oysters by the unicellular pathogen Perkinsus marinus have been associated with anthropogenic influences in laboratory studies. However, these relationships have been difficult to investigate in the field because anthropogenic inputs are often associated with natural influences such as freshwater inflow, which can also affect infection levels. ...

During the late 1990s, increases in referrals to the national reference laboratory of Streptococcus pyogenes isolates from injecting drug users (IDUs) with severe soft tissue infection indicated an emerging problem in the UK, later confirmed during the 2003-2004 European enhanced surveillance (Strep-EURO) programme. In light of these findings, further analyses ...

Iridoviruses of the genus Ranavirus are well known for causing mass mortality events of fish and amphibians with sporadic reports of infection in reptiles. This article describes five instances of Ranavirus infection in chelonians between 2003 and 2005 in Georgia, Florida, New York, and Pennsylvania, USA. Affected species included captive ...

Amebiasis is defined as infection with Entamoeba histolytica, regardless of associated symptomatology. In resource-rich nations, this parasitic protozoan is seen primarily in travelers to and emigrants from endemic areas. Infections range from asymptomatic colonization to amebic colitis and life-threatening abscesses. Importantly, disease may occur months to years after exposure. Although ...

Balsalazide is a 5-amino salicylic acid prodrug well-tolerated and effective in treating acute ulcerative colitis. VSL[sharp]3, a high-potency probiotic mixture, has proved to be effective in preventing flare-ups of chronic pouchitis and in obtaining remission of mild-to-moderate ulcerative colitis. Recent studies found the association of low-dose balsalazide/VLS no. 3 effective ...

Acute diarrheal illness is a global health problem that may be exacerbated by concurrent infection. Using Citrobacter rodentium, a murine model of attaching and effacing diarrheagenic Escherichia coli, we demonstrate that persistent Helicobacter hepaticus infection modulates host responses to diarrheal disease, resulting in delayed recovery from weight loss and from ...

Bovine reproductive failure caused by the parasite Neospora caninum is a major problem and is responsible for severe economic losses worldwide. Currently, appropriate control measures depend on the predominant transmission route in a particular herd. Therefore, the development of diagnostic tools capable of discriminating between primo-infection, recrudescence, re-infection, and chronic ...

The risk of thromboembolism is increased in inflammatory bowel disease and its symptoms may be overlooked. Furthermore, its treatment can be complex and is not without complications. We describe a case of an adolescent boy who developed a cerebral sinus venous thrombosis during a relapse of his ulcerative colitis and ...

Mycoplasma agassizi has been identified as a cause of upper respiratory tract disease (URTD) in the threatened Mojave population of the desert tortoise (Gopherus agassizii), and anti-M. agassizii antibodies have been found by ELISA in as many as 15% of these animals across their geographic range. Here we report that ...

In recent years, honeybees (Apis mellifera) have been strangely disappearing from their hives, and strong colonies have suddenly become weak and died. The precise aetiology underlying the disappearance of the bees remains a mystery. However, during the same period, Nosema ceranae, a microsporidium of the Asian bee Apis cerana, seems ...

BACKGROUND: The time trends of inflammatory bowel disease are characterized by short-term variations that affect Crohn's disease and ulcerative colitis alike. The aim of the present study was to test whether these variations might be related to exacerbations of inflammatory bowel disease secondary to superimposed gastrointestinal infection. METHODS: The Hospital ...

PURPOSE OF REVIEW: Advances in conventional therapy, novel targets and therapeutic goals are the highlights of treatment for ulcerative colitis in the last year. There have also been disappointments. This review summarizes the highs and lows, with an emphasis on strategy as opposed to seeking the newest treatment option. RECENT ...

Scuticociliatosis is a disease of fish induced by ciliated parasites of the genus Scuticociliatida. It has been described in sea horses (Hippocampus sp.), flounders (Paralichthys olivaceus), and turbots (Scophthalmus maximus). Here we present a case study of a population of sea dragons chronically infected with scuticociliates identified as Philasterides dicentrarchi ...

Fecal carriage of extended-spectrum-beta-lactamase (ESBL)-producing organisms was detected in 70% of index cases of patients (n = 40) with community-acquired infections due to ESBL producers and reached 16.7% in household contacts (n = 54). A total of 66% of ESBL-producing organisms from index cases were indistinguishable from isolates from household ...

The pathological condition of the short-neck clam Ruditapes philippinarum was surveyed along the coast of Kumamoto, Japan, in June 2004. DNA sequences of the non-transcribed spacer region and internal transcribed spacer region flanking 5.8S rRNA identified Perkinsus olseni among the clams. Ray's fluid thioglycollate medium assay indicated that 96.7% of ...

Intracolonic administration of Trichinella spiralis larvae in rats causes colitis with features similar to ulcerative colitis, notably with inflammation predominantly limited to the colonic mucosa. Our aim was to characterize the functional and neurochemical changes occurring within the myenteric (MP) and submucosal plexuses (SMP) during T. spiralis-induced colitis. Infected rats ...

Multiple myeloma is associated with a high risk of infections. We hypothesized that Fc gamma receptor (FCGR) and myeloperoxidase (MPO) promoter gene polymorphisms influence the risk of infections after induction chemotherapy (IC) and autologous stem cell transplantation (ASCT). Retrospectively, we analysed 136 patient courses of IC and 113 procedures of ...

The clinical impact of human metapneumovirus (hMPV) genotypes and the relation between the hMPV genotype in circulation and genotype-specific seroprevalence are yet to be clarified. We determined the genotypes of 93 hMPV strains that were isolated between 2004 and 2006 in Yamagata, Japan, and identified 35 genotype A2, 14 genotype ...

In 2004-2006, 322 brood horses from 11 horse farms were examined using the faecal egg count reduction test (FECRT) to determine the presence and distribution of anthelmintic resistance in strongylids in Ukraine. The anthelmintic drugs "Albendazole-7.5" (7.5mg of albenazole, Ukraine) at a dose of 5mg per kg body weight and ...

Takayasu arteritis (TA) is a chronic inflammatory disease that involves the aorta and its major branches. Since overproduction of interleukin-6 (IL-6) seems to play a pathogenic role in TA, we used the anti-IL-6 receptor (IL-6R) antibody tocilizumab to treat a 20-year-old woman with refractory active TA complicated by ulcerative colitis ...

Noma, or cancrum oris, is a debilitating necrotizing ulcerative stomatitis that destroys the mouth and face. It usually starts in early childhood and is associated with severe poverty, malnutrition, and infections. It is most frequently described from sub-Saharan Africa but is under-reported. There have been very few reports from Asia. ...

The purpose of the present study was to identify Echinococcus multilocularis infection in follow-up of 95 subjects initially seropostive by Emc-ELISA or Emf-ELISA antibody assays and to compare the utility of these assays with specific Em2plus-ELISA and ultrasound screening for E. multilocularis infection. At follow-up seven subjects were seropositive with ...

Opisthorchiasis caused by Opisthorchis viverrini remains a major public health problem in many parts of Southeast Asia, including Thailand, Lao PDR, Vietnam and Cambodia. The infection is associated with a number of hepatobiliary diseases, including cholangitis, obstructive jaundice, hepatomegaly, cholecystitis and cholelithiasis. Multi-factorial etiology of cholangiocarcinoma, mechanical damage, parasite secretions, ...

A female boa (Boa constrictor) from a zoological collection was submitted for necropsy after sudden death. Prominent pathological findings included a diphtheroid colitis, endoparasitism, focal pneumonia and inclusion bodies typical for inclusion body disease (IBD). In the colon entamoebae were identified, which differed in size and distribution from Entamoeba invadens. ...

Acinetobacter baumannii is most often responsible for hospital-acquired infections and is occasionally associated with community-acquired infections. We report two cases of A. baumannii endophthalmitis, one with endogenous endophthalmitis and the other with postkeratoplasty endophthalmitis. Although endophthalmitis is rare, ophthalmologists should be alert to the possibility of patients having endophthalmitis caused ...

Anoplocephala perfoliata (Cestoda, Cyclophyllidea), the commonest intestinal tapeworm of horses, can cause colic, intussusceptions, ileal impactions and intestinal perforations. Common diagnostic techniques for A. perfoliata infection, i.e. coprology and serology, show inherent limitations in terms of sensitivity and specificity and new approaches are thus required. Hence, the present study compared ...

Borna Disease Virus (BDV) is a unique RNA virus, whose organs of manifestation are the brain and blood of animals as well as humans. The infection disrupts certain cell functions, but does not damage the cell structure. The infection with BDV can exist without associated clinical symptoms. Furthermore the majority ...

INTRODUCTION: Barbiturate coma is a necessary medical therapy in certain instances, such as the treatment of refractory status epilepticus or severe intracranial hypertension, but its use is often wrought with serious complications. Potential complications include hemodynamic instability, respiratory depression, and immunosuppression with frequent nosocomial infections. High doses of barbiturates may ...

ABSTRACT: Blastocystis is a prevalent enteric protozoan that infects a variety of vertebrates. Infection with Blastocystis in humans has been associated with abdominal pain, diarrhea, constipation, fatigue, skin rash, and other symptoms. Researchers using different methods and examining different patient groups have reported asymptomatic infection, acute symptomatic infection, and chronic ...

An interaction between infection and IBD was identified soon after Crohn's disease and ulcerative colitis were first described. Since then it has become apparent that infectious agents are involved with both the etiopathogenesis and clinical course of IBD on several levels. Whilst our understanding of this interplay is incomplete, it ...

Although horse cases frequently are reported during West Nile virus (WNV) outbreaks, few investigations have focused on the epidemiology of this transmission. From April to October 2003 to 2005, mosquito abundance and infection were monitored 3 days per week at an equine research facility at the University of California, Davis. ...

We report a Japanese patient with loiasis who became infected in Cameroon. Despite the clinical history and laboratory data providing adequate evidence for suspecting loiasis, microfilariae were not detected in the blood. It is important to note that most infected travelers whose home countries are in nonendemic regions are amicrofilaremic.
