Molecular epidemiology and genotype distribution of noroviruses in children in Thailand from 2004 to 2010: a multi-site study.

This study identified norovirus in children presenting with acute gastroenteritis and determined the capsid genotypes of the circulating norovirus strains in multiple regions in Thailand during October 2004 to December 2006 and March 2008 to August 2010. A total of 7,420 stool samples were collected from both cases (3621) and controls (3799). The stool samples were screened by two real-time RT-PCR assays to detect genogroup I and genogroup II noroviruses.

Persistent diarrhea: 15 years experience at a tertiary care hospital.

Objective: To determine the risk factors, causative enteric pathogens, final diagnosis and treatment outcomes of persistent diarrhea in children.

Material And Method: A retrospective study of the patients who had diarrheal symptoms for at least 14 days diagnosed as persistent diarrhea (PD) and admitted at QSNICH during January 1997 and December 2011. Demographic data, risk factors, causative enteric pathogens, management and outcome were reviewed.

Clinical features of gastrointestinal salmonellosis in children in Bangkok, Thailand.

This retrospective descriptive study was conducted at Queen Sirikit National Institute of Child Health (QSNICH), Bangkok, Thailand to describe the clinical features of gastrointestinal salmonellosis in children. The medical records of 134 patients admitted to QSNICH in 2009 who had a positive stool culture for Salmonella spp were reviewed. Demographic, clinical, laboratory, treatment, culture and antimicrobial sensitivity data were collected and analyzed.

Hepatocellular carcinoma in children presents with massive upper gastrointestinal bleeding: a case report.

Hepatocellular carcinoma (HCC) is a very rare pediatric tumor. The incidence is 0.5-1.

Eosinophilic gastrointestinal disease: analysis of sixteen cases from ten years experience in Thailand.

Objective: To study eosinophilic gastrointestinal disease (EGIDs) in children concerning the clinical presentations, diagnostic methods and results of treatment.

Material And Method: A retrospective study of EGIDs was done from January 2000 to December 2009. All patients diagnosed as EGIDs according to gastrointestinal symptoms combined with eosinophilic infiltration in mucosal, muscular or serosal layer of involvement.

Gastrointestinal manifestations in severe strongyloidiasis: report of 3 cases and literature review.

We report here three cases of severe strongyloidiasis in normal and immunocompromised hosts. The first was a patient with a normal immune system who presented with acute severe abdominal pain. The second and third patients were immunocompromised due to steroid and chemotherapy treatment of underlying diseases.

Chronic diarrhea and abnormal serum immunoglobulin levels: a case report.

A 15-year-old Thai boy with multiple episodes of chronic diarrhea caused by giardiasis with hypogammaglobulin M and IgG4 subclass deficiency (but normal antibody response to rabies vaccine) is reported. Immune status follow-up is necessary for a definite diagnosis and proper management.

A rapid serologic test and immunoblotting for the detection of Helicobacter pylori infection in children.

The gold standard for the diagnosis of Helicobacter pylori infection requires an endoscopic biopsy of gastric mucosa for histological examination, urease test and culture. Noninvasive serological tests are useful as a screening test for H. pylori infection.

Childhood Helicobacter pylori infection, clinical presentations, endoscopic, histologic features and results of treatment.

Objective: To study childhood Helicobacter pylori infection concerning the clinical presentations, endoscopic, histologic features and results of treatment.

Material And Method: A retrospective study conducted at the Gastroenterology and Nutrition Unit, Queen Sirikit National Institute of Child Health (QSNICH) was done from January 1993 to December 2002. All patients presented with recurrent abdominal pain, upper GI bleeding (non-variceal bleeding) chronic vomiting and dyspeptic symptoms who underwent upper GI endoscopy were included in this study.

Intussusception associated with a relapsing nephrotic patient: a case report.

Background: Gastrointestinal disturbances are encountered frequently in the course of the nephrotic syndrome but intussusception is a rare association. It may be the result of incoordinate motility and bowel wall edema.

Objective: To report a case of intussusception associated with relapsing nephrotic syndrome.

Comparative antibiotic resistance of diarrheal pathogens from Vietnam and Thailand, 1996-1999.

Antimicrobial resistance rates for shigella, campylobacter, nontyphoidal salmonella, and enterotoxigenic Escherichia coli were compared for Vietnam and Thailand from 1996 to 1999. Resistance to trimethoprim-sulfamethoxazole, ampicillin, chloramphenicol, and tetracycline was common. Quinolone resistance remains low in both countries, except among campylobacter and salmonella organisms in Thailand.
