Fungal colonization in the neonatal intensive care unit: risk factors, drug susceptibility, and association with invasive fungal infections.

A prospective study was conducted to determine risk factors for fungal colonization, drug susceptibility, and association with invasive fungal infections (IFIs) in a neonatal unit. On admission and weekly thereafter, surveillance fungal cultures were taken from mouth, rectum, and trachea of neonates with expected stays of > 1 week. Fungal colonization was detected in 72 (12.

Hypoxia-ischemia affects erythropoietin and erythropoietin receptor expression pattern in the neonatal rat brain.

Erythropoietin (EPO), known for its role in erythroid differentiation, has been suggested to have non-hematopoietic functions in the brain, especially during development. In the present study, we investigated the expression of erythropoietin and erythropoietin receptor (EPOR) in the developing rat brain following hypoxia-ischemia. Seven-day-old rats underwent unilateral, permanent carotid artery ligation followed by 1 h of hypoxia, and their brains were examined immediately, 24 h or 4 days after hypoxia-ischemia.

Candida tropicalis in a neonatal intensive care unit: epidemiologic and molecular analysis of an outbreak of infection with an uncommon neonatal pathogen.

From June to July 1998, two episodes of Candida tropicalis fungemia occurred in the Aristotle University neonatal intensive care unit (ICU). To investigate this uncommon event, a prospective study of fungal colonization and infection was conducted. From December 1998 to December 1999, surveillance cultures of the oral cavities and perinea of the 593 of the 781 neonates admitted to the neonatal ICU who were expected to stay for >7 days were performed.

Trichosporon asahii: an unusual cause of invasive infection in neonates.

Trichosporon asahii causes white piedra, an infection of hair shafts and onychomycosis in immunocompetent patients, as well as various localized or disseminated invasive infections in immunodeficient hosts. We describe a 26-week gestation 890-g vaginally delivered female neonate who had severe respiratory distress syndrome and on the sixth day of life developed Klebsiella pneumoniae sepsis. At the same time two blood cultures were positive for T.
