RESUMO
Las tasas de supervivencia de los recién nacidos prematuros se han incrementado gracias a los avances tecnológicos y los conocimientos en constante evolución, aunque la sepsis de aparición tardía es más frecuente debido a los períodos prolongados de hospitalización de estos niños. Presentamos el caso de un recién nacido prematuro de extremadamente bajo peso al nacer hospitalizado con síndrome de dificultad respiratoria, enterocolitis necrosante y sepsis fúngica con endocarditis por Candida albicans. Se le administró tratamiento antimicótico hasta que se resolvió la vegetación fúngica. La sepsis y la endocarditis de origen micótico podrían ser una causa de morbilidad significativa en los recién nacidos prematuros. En este artículo revisamos las publicaciones científicas recientes acerca de los factores de riesgo, el diagnóstico, el tratamiento y la prevención de la sepsis fúngica en estos neonatos de alto riesgo.
Survival rates of premature infants have increased with developing technology and evolving knowledge but late-onset sepsis is more frequent due to prolonged hospitalization periods of these infants. We report the case of an extremely low birth weight premature infant who was admitted with respiratory distress syndrome, developed necrotizing enterocolitis and fungal sepsis with endocarditis by Candida albicans. He was treated with antifungal therapy until fungal vegetation resolved. Fungal sepsis and endocarditis may be an important morbidity in preterm infants; we review the recent literature about the risk factors, diagnosis, treatment and prevention of fungal sepsis in these high risk infants.

OBJECTIVE: Helicobacter pylori ( H.pylori ) infection is usually acquired in early childhood. Invasive techniques used for diagnosis of H.pylori infection require endoscopic examination which is expensive and inconvenient and may cause complications. The aim of this study was to evaluate the performance of a new noninvasive diagnostic method, stool antigen test for H.pylori in untreated children with recurrent abdominal pain. METHODS: Eighty children (35 female, 45 male) who have undergone upper gastrointestinal endoscopy due to recurrent abdominal pain were included in the study. The H.pylori stool antigen test (HpSA) is based on a sandwich enzyme immunoassay with antigen detection. HpSA sensitivity, specificity, and positive and negative predictive values were determined with reference to the results of both histology and rapid urease test as a gold standard ( H. pylori status). RESULTS: While 49 of the 80 children (61%) tested were positive for H.pylori according to the results of both histology and rapid urease test, 28 children had negative H.pylori status. Among those 49 children, 48 were found to be positive by HpSA. Of 28 patients with negative H.pylori status, 28 were H.pylori -negative also in the stool test. The sensitivity, specificity, and positive and negative predictive values of HpSA were found to be 98%, 100%, 100%, and 96.5%, respectively. CONCLUSION: These findings have demonstrated that HpSA as a relatively simple, inexpensive and time saving noninvasive test is a reliable method for detection of H.pylori infections in children.
