Value of the International Classification of Diseases code for identifying children with biliary atresia.

Background: Although identifying cases in large administrative databases may aid future research studies, previous reports demonstrated that the use of the International Classification of Diseases, Tenth Revision (ICD-10) code alone for diagnosis leads to disease misclassification.

Purpose: We aimed to assess the value of the ICD-10 diagnostic code for identifying potential children with biliary atresia.

Methods: Patients aged <18 years assigned the ICD-10 code of biliary atresia (Q44.

Various initial presentations of Epstein-Barr virus infection-associated post-transplant lymphoproliferative disorder in pediatric liver transplantation recipients: Case series and literature review.

PTLD is a rare but potentially life-threatening condition, which shows a higher prevalence in children than in adults. From 129 children who underwent LT, we reported 5 cases with biopsy-proven PTLD at a single teaching hospital. Four patients had shared clinical presentations including fever, lymphadenopathy, and splenomegaly.

No association between month of birth and biliary atresia in a country with tropical climate.

Aim: Children with biliary atresia (BA) born in countries with temperate climate showed month-of-birth (MoB) predilection during cooler months. To date, no study on the MoB-BA association has been performed in a tropical country. Our aim was to define MoB variation in children with BA in a tropical country.

Inflammatory bowel disease in Thai children: presentations and outcomes of treatment.

Inflammatory bowel disease (IBD) is characterized by idiopathic chronic intestinal inflammation, due to abnormalities in gastrointestinal immunoregulation. Pediatric IBD has been rarely reported in Thailand. We describe eight children, five girls and three boys, who were diagnosed with IBD at Ramathibodi Hospital during 1999-2005 and had a follow-up of more than one year.

Effect of bifidobacterium Bb12 with or without Streptococcus thermophilus supplemented formula on nutritional status.

Acute diarrhea is a common cause of infant morbidity and mortality. Probiotic supplemented infant formula is one of the effective methods for prevention of rotavirus diarrhea. Other benefits of the probiotics supplemented formula were evaluated by monitoring the growth of the children.

Henoch-Schonlein purpura: clinical manifestations and long-term outcomes in Thai children.

The clinical features of 47 children with Henoch-Schonlein purpura (HSP) are presented. The most common ages at presentation ranged from 3-5 years. Duration of data collection was 60 months.

Effect of oral vitamin E supplementation in children with cholestasis.

Objective: Malabsorption and deficiency of vitamin E are common consequences of chronic cholestasis. The objective of this study was to determine vitamin E status by using plasma vitamin E/total lipid ratio (E/L) in children with cholestasis during supplementation with 20 IU/kg/day and 100 IU/kg/day of oral vitamin E capsule, and 50 IU/kg/day of cold water soluble form (CWSIF) of vitamin E.

Method: Children with cholestasis who were being supplemented with 20 IU/kg/day of oral vitamin E capsule (dl-alpha-tocopherol) were enrolled into this study.

Disseminated intravascular coagulation findings in 100 patients.

A retrospective study of 100 patients with disseminated intravascular coagulation from 1993 to 1997 is reported. Forty-five patients were neonates with a mean age of 12.6 days and 55 patients were infants, children and adolescents with a mean age of 6 years and 3 months.

Reduction of rotavirus infection in children receiving bifidobacteria-supplemented formula.

This study was conducted at Pakkred Babies Home, Bangkok, Thailand; with the hypothesis that children receiving probiotic-supplemented milk-based formula may be protected from developing diarrheal diseases. Salivary rotavirus-specific IgA antibody was used as an indicator of rotavirus infection. One hundred and seventy-five children, aged 6-36 months, were enrolled in the study.

Rabies.

Rabies is a complex disease. We still do not understand the mechanisms of clinically diverse furious and dumb types and its fatal course. Moreover clinical symptomatology, once believed to be unique, may be variable, particularly in those patients who develop disease after exposure to virus of the insectivorous or frugivorous bat origin.

Single oral loading dose of phenytoin: a pharmacokinetics study.

In order to determine the optimal single oral loading dose of phenytoin in patients with seizures, a two part study of phenytoin pharmacokinetics was conducted. In the first part, 15 mg/kg of phenytoin was given orally as a single dose to 19 normal medical volunteers with informed consent. Serum concentrations of phenytoin reached the therapeutic level (10 micrograms/ml) with an average of 2.

Gastroesophageal reflux in children: correlation of symptoms with 24-hour esophageal pH monitoring.

To evaluate the clinical significance of suspected symptoms of GER, 24-hour esophageal pH monitoring was performedin 55 children (mean age of 23.9 months). We used 24-hour esophageal pH monitoring as a gold standard for the diagnosis of pathological GER.

Effect of steroids on cerebrospinal fluid penetration of antituberculous drugs in tuberculous meningitis.

Sixteen patients with oral isoniazid, pyrazinamide, rifampin, and intramuscular streptomycin for tuberculous meningitis were studied. The concentrations of isoniazid, pyrazinamide, rifampin, and streptomycin in cerebrospinal fluid (CSF) obtained 3 hours after administration were 2.40, 34.

The blood/cerebrospinal fluid partitioning of pyrazinamide: a study during the course of treatment of tuberculous meningitis.

Concentrations of pyrazinamide were measured in serum and cerebrospinal fluid (CSF) of 17 adult patients with tuberculous meningitis up to six months after starting treatment. Pyrazinamide penetrated excellently into the CSF and mean concentrations at various intervals up to six months of treatment were consistently above that required for inhibition of the growth of Mycobacterium tuberculosis. The blood/CSF partitioning of pyrazinamide does not change as the patients recover from the meningitis.

HBsAg carrier rate among institutionalised children from Phyathai Institute.

To identify the evidence supporting the horizontal transmission of hepatitis B virus, HBsAg carrier rate among institutionalised children is determined and compared to children of the same age-group from the well baby clinic, Ramathibodi hospital. The results of this study show that HBsAg is detected four times more frequently in institutionalised children than in children from a well baby clinic. The chance of becoming an HBsAg carrier increases with age and duration of stay in the institution.

Liver size and serum alkaline phosphatase in normal Thai school-aged children.

The purpose of this study is to determine liver size in normal Thai school children aged 6 to 11 years, using both the clinical and ultrasonographic methods. Normal value of serum alkaline phosphatase in this age-group is also obtained. To confirm that liver function is normal, serum alanine transaminase and hepatitis B virus profile were performed.

Severe hepatitis B in infants born to HBsAg carrier mothers.

Five infants admitted consecutively with severe hepatitis B were treated with exchange transfusion, correction of coagulation defects and supportive measures. All were born to HBsAg carrier mothers and one had received hepatitis B immune globulin (HBIG) within 24 hours after birth. All of them presented with nonspecific symptoms such as vomiting, loose stools, low grade fever and progressed to acute liver failure.

Failure of norfloxacin to eradicate intestinal colonization of non-typhoidal salmonella in infants.

Infant colonization with non-typhoidal Salmonella (NTS) is common and eradication is problematic. Oral norfloxacin has promising properties for solving this problem, though it has potential toxicity to infants. The drug has been available in Thailand since 1987.

Etiology of diarrhea in measles.

Thirty-six measles cases with diarrhea were studied with two age and sex matched control groups, measles without diarrhea (75 cases) and acute diarrhea (70 cases). Bacterial pathogens were isolated from 5 out of 36 (13.9%) in measles with diarrhea but rotavirus, coronavirus and parasites were not detected in any case.

Rapid diagnosis of rabies and post-vaccinal encephalitides.

In an attempt to establish the diagnoses of rabies post-vaccinal encephalitis (PVE) and early rabies encephalitis, paired serum and CSF levels of rabies neutralizing antibody (Rab) and rabies specific-IgM (RIgM) were compared in 12 PVE, 10 rabies and five control patients with similar presenting clinical features. Rapid methods of rabies antigen detection were evaluated in 17 patients. All 12 PVE patients had Rab in their serum and in eight it was also present in the CSF.

Treatment of tuberculous meningitis: role of short-course chemotherapy.

Twenty-eight adult patients admitted consecutively with tuberculous meningitis were treated with pyrazinamide, isoniazid, rifampicin and streptomycin daily during the first two months, followed by isoniazid and rifampicin daily for seven months with intensive management of the complications during the active stage of the meningitis. Twenty-two patients completed the course of treatment and recovered with minimal morbidity in three patients. Two patients died in a vegetative state from other causes seven and nine months after the start of treatment.
