[Clinical-epidemiological characterization of neonatal necrotizing enterocolitis of seven public hospitals].

Background: Necrotizing enterocolitis (NEC) presents high mortality and postoperative, gastrointestinal and neurodevelopmental morbidity. There is limited information about NEC in Chile.

Aim: To describe the clinical/epidemiological behavior of newborns who underwent NEC.

[Antibiotics in neonatology. Part I: Dosage recommendations based on the most recent evidence in newborns Advisory Committee on Neonatal Infections, Chilean Society of Infectious Diseases].

Antibiotics are the most widely used medications in neonates during their first month of life in neonatal units, mainly due to the high risk they present of acquiring serious infections such as sepsis. Most of these antibiotics are used with extrapolated doses based on the suggestions in the adult population and older children, despite the fact that the pathophysiology in newborns is absolutely different. This leads to a higher risk of more adverse effects occurring, which can lead to greater toxicity and therapeutic failures, among others.

[Neonatal herpes simplex encephalitis: two twins, two cases].

Herpes simplex encephalitis is an infrequent infection with high mortality and morbidity. Antiviral therapies decrease mortality but long term sequelae are still high, so early diagnosis is important for opportune treatment. We present a pair of twins with central nervous system herpes simplex infection during the first month of life.
