During the past two decades, cholelithiasis has been recognized in increasing numbers of pediatric patients. This diagnosis should be considered in the event of upper abdominal complaints, particularly when one or more risk factors are evident. The etiology may be unknown or may be related to risk factors, including hemolytic conditions. In recent years, it has become evident that approximately 80% of gallstones in children are not due to hemolytic disease and that the remaining 20% are related to recurring hemolysis. The diagnosis of gallstones is best confirmed with ultrasonography. Routine ultrasonographic evaluation should be performed at intervals for all children who received TPA for more than 4 weeks, particularly those who have had ileal resection or have had chronic enteritis (Crohn disease). Cholecystectomy is the procedure of choice for symptomatic children with cholelithiasis, regardless of age. Cholecystectomy is recommended for the asymptomatic child younger than 3 years of age when echogenic shadows have been present for at least 12 months following resumption of oral feedings or when the gallstones are radiopaque. Also, cholecystectomy is advised for asymptomatic children who are older than 3 years of age if ultrasonographic studies confirm that echogenic foci with shadowing are true stones and not echogenic sludge. Complications of common bile duct obstruction, pancreatitis, perforation with bile peritonitis, and life-threatening sepsis may thus be prevented. Morbidity and mortality following cholecystectomy are expected to be relatively low in the pediatric age group.

Previous studies have shown enteral nutritional solutions (ENS) contaminated with large numbers of microorganisms from the environment or gastrointestinal (GI) tract of patients have caused respiratory infections, acute and chronic enteritis, and septicemia. The introduction of "closed" enteral feeding systems has been used to prevent contaminating organisms from entering enteral feeding systems in large numbers. However, there is some discussion as to whether this has been an effective measure in reducing ENS-related infections because there is anecdotal evidence to suggest that disease processes resulting from enteral feeding are still commonplace in the hospital and home. This is because there is very little information about the growth of microorganisms in ENS and whether growth in ENS may affect the virulence and pathogenicity of microorganisms. This study shows that Escherichia coli and Pseudomonas aeruginosa may grow at 25 degrees C from either high or low initial numbers to up to 9.2 log colony-forming units per mL in a range of milk-based ENS. However, these organisms did not grow in the fruit-based ENS. The effect on the lipopolysaccharide (LPS) of culturing E. coli and P. aeruginosa in milk-based ENS as opposed to standard laboratory media was examined using polyacrylamide gel electrophoresis. We found that there were significant qualitative changes in the phenotype of O-polysaccharide side chains of the LPS from these organisms. O-polysaccharide is known to mediate in the complement, antibiotic and bile resistance, and affect adherence. Therefore, changes in the virulence and pathogenicity of these microorganisms when cultured in ENS may be indicated. Thus, the study provides further evidence for reevaluating the microbiologic and immunologic effects of enteral feeding, especially on the microbial flora of the GI tract.

Salmonella infection can cause septicemia, acute or chronic enteritis and wasting in weaned pigs, but may occur in other age groups. The bactericidal/permeability-increasing protein (BPI) gene plays an important role in the natural defense of the host and is found to be associated with resistance/susceptibility to Salmonella infection and identified as a candidate gene for disease resistance breeding in pig. This study was conducted to screen the resistance and/or susceptibility of pigs to Salmonella infection, to determine the genotype and evaluate presence of resistant allele of the BPI gene in population of pigs, and to establish genetic data for pig breeders for the improvement of Philippine pig industry. In this study, 389 blood samples from different pig breeds were collected from pig breeder farms in the Philippines. Genomic DNA was extracted from these samples and genotyping was done by PCR-RFLP analysis using AvaII restriction enzyme. Out of 389 pigs, the genotypic frequency showed that 98.4, 1.3, and 0.3% pigs are resistant (GG), heterozygous type (AG), and susceptible (AA), respectively. The application of BPI gene as marker for disease resistance will provide information to the pig industry to implement strategies for the identification of Salmonella infection-resistant pigs.

Stenotrophomonas maltophilia is an emerging opportunistic pathogen linked not only to bacteremia, sepsis, and pneumonia but also to severe chronic enteritis. Persons with the impaired immune system are prone to be infected by S. maltophilia since its pathogenicity seems to be more associated with the host immune system than with the acquisition of specific virulence genes. In the dairy chain, S. maltophilia is linked to clinical and subclinical bovine mastitis in dairy cows, and it has been identified in cheese, and raw and pasteurized milk. There are reports of misidentification of S. maltophilia by commercial systems and PCR assays using primers based on the 23S rRNA and smeD genes, so the smeT gene is an alternative to identifying S. maltophilia by PCR due to its specificity to the S. maltophilia species. The present study reports an alternative species-specific PCR assay based on the smeT gene designed to identify S. maltophilia in cheese samples. We performed in silico and in vitro analyses to check the specificity of the primer pair. In silico analysis showed specificity of the primer pair to the species level. In vitro analysis was performed by testing the primer pair against pools of bacteria grown from 33 fresh Minas cheese samples acquired in the city of Rio de Janeiro, Brazil, without unspecific amplification.
