BACKGROUND: Dengue is endemic throughout Cambodia, a country faced with significant health and economic challenges. We undertook a clinical study at the National Paediatric Hospital in Phnom Penh to evaluate clinical diagnostic parameters for dengue and predictors of disease outcome. METHODS: Between September 2011 and January 2013, all consecutive inpatients aged between 1 and 15 years and presenting with suspected dengue were enrolled. They were clinically assessed using both the 1997 and 2009 WHO dengue classifications...

Biliary atresia (BA) is a pediatric inflammatory disease of the biliary system which leads to cirrhosis and the need for liver transplantation. Various cells types have been reported to participate in the pro-inflammatory response, including Th1, Th2, Th17, CD8(+) T cells, or NK cells. The suppressive Treg cells, on the contrary, were not functioning properly. The underlying mechanism is largely unknown. Focusing on why the suppressive function of Treg was impaired, we found out methylation status of CpG islands within the Foxp3 promotor of Tregs in BA patients and murine models were both increased...

Solid organ transplant (SOT) recipients may develop protracted diarrheal illness from norovirus. We performed a retrospective chart review between January 2010 and April 2014 to identify predictors of persistent diarrhea in transplant recipients with norovirus enteritis. A total of 152 SOT recipients with mean age of 31.5 years (SD 23.1) were included: 43.4% male, 34.2% pediatric patients. Allograft types were abdominal 136 (89.5%) (kidney [39.5%], liver-small bowel [23%], other [27%]) and thoracic 16 (10...

Human toxocarosis is a chronic larval parasitosis listed as one of the five most important neglected diseases by the CDC. The larvae can spread systemically and migrate to different tissues including liver and gallbladder. Acalculous acute cholecystitis (AAC) is a rare disease in children. The diagnosis is based on clinical parameters and imaging criteria. It has been reported in relation to sepsis, shock, trauma, burns, severe systemic diseases, congenital anomalies, infections and also in healthy children...

Cat-scratch disease (CSD) is a zoonosis in children, result of infection by Bartonella henselae, a gram-negative bacillus. Infection is generally characterized by regional and self-limited lymphadenopathy after exposure to a scratch or bite from a cat. Rarely, B. henselae is cause of fever of unknown origin (FUO), with dissemination to various organs, most often involving the reticuloendothelial system (liver, spleen, bone marrow), mimicking an inflammatory rather than a lymphoproliferative disease. Whole-body Magnetic Resonance Imaging (WBMRI), in association with diffusion-weighted imaging (DWIBS), allows a comprehensive evaluation of pediatric patients, without the risks inherent to ionizing radiation...

BACKGROUND: Hemophagocytic lymphohistiocytosis (HLH) is a rare, potentially fatal disorder characterized by fever, pancytopenia, hepatosplenomegaly, and increased serum ferritin. HLH is being increasingly reported as a complication of dengue, a common tropical acute febrile illness. METHODOLOGY/PRINCIPAL FINDINGS: After a cluster of pediatric dengue-associated HLH patients was identified during the 2012-2013 dengue epidemic in Puerto Rico, active surveillance and a case-control investigation was conducted at four referral hospitals to determine the incidence of HLH in children and identify risk factors for HLH following dengue...

Entamoeba histolytica, the etiological agent of amebiasis, is a significant cause of pediatric diarrhea in South Asia and sub-Saharan Africa. The clinical outcome of an E. histolytica exposure varies enormously and can present as diarrhea, dysentery, or amebic liver abscess. Host and parasite factors likely contribute to the outcome of infection with the parasite, but do not explain the wide variation in presentation of disease. This suggests that other environmental factors affect disease. An emerging body of work suggests that the host intestinal bacterial microbiome may have a significant influence on the development and outcome of amebiasis...

BACKGROUND: Cytomegalovirus (CMV) is 1 of the most common causes of infection after solid organ transplantation with symptomatic disease occurring at an incidence of 20-40% without preventative measures. While CMV donor+/recipient- serostatus is well known to be a risk factor, there is little data about other risk factors for CMV infection in the setting of pediatric liver transplantation (LT). We hypothesized that fulminant hepatic failure (FHF) may be a risk factor for CMV infection given anecdotal reports of complications associated with FHF...

Hepatitis C virus (HCV) infection is a major medical challenge affecting around 200 million people worldwide. The main site of HCV replication is the hepatocytes of the liver. HCV is a positive enveloped RNA virus from the flaviviridae family. Six major HCV genotypes are implicated in the human infection. In developed countries the children are infected mainly through vertical transmission during deliveries, while in developing countries it is still due to horizontal transmission from adults. Minimal nonspecific and brief symptoms are initially found in approximately 15% of children...

We herein present the case of a four-yr-old boy with PA who developed AMR after ABO-incompatible LDLT despite undergoing B cell desensitization using rituximab. Although the CD19+ lymphocyte count decreased to 0.1% nine days after the administration of rituximab, he developed a high fever which was accompanied by arthralgia due to a streptococcal infection 13 days after rituximab prophylaxis. After the clearance of the infection, he underwent ABO-incompatible LDLT 36 days after the administration of rituximab...

INTRODUCTION: Hematopoietic cell transplantationis a therapy with a risk of transplant-related mortality (TRM), which may vary depending on prior comorbidities. The Hematopoietic Cell Transplantation-Specific Comorbidity Index (HCT-CI) is an instrument developed to measure this risk. There are very few reports on its use in pediatrics. The objective of this study was to validate the HCT-CI in a pediatric cohort of allogeneic hematopoietic-cell transplantation recipients in Argentina. POPULATION AND METHODS: Retrospective cohort made up of 140 transplant patients a, Hospital J...

In pLT recipients, the advantages of ICVCs need to be weighed against the risk of complications. This single-center retrospective study aimed to review ICVC complications in our cohort of pLT recipients. We performed chart reviews of pLT patients having undergone transplant between 01/2000 and 03/2014 and who underwent ICVC placement either before or after LT. We identified 100 ICVC in 85 patients. Overall observation time was 90 470 catheter-days. There was no difference in catheter lifespan between those inserted pre- or post-transplant; 46% of ICVC presented a complication...
