Impact of quality improvement outreach education on the incidence of acute brain injury in transported neonates born premature.

OBJECTIVE: To evaluate impact of a quality improvement (QI) outreach education on incidence of acute brain injury in transported premature neonates. STUDY DESIGN: Neonates born at <33 weeks gestation outside the tertiary center were included. The QI intervention was a combination of neuroprotection care bundle, in-person visits, and communication system improvement. Descriptive and regression (adjusting for Gestational Age, Birth Weight, Gender, and antenatal steroids, Mode of delivery, Apgars at 5 minutes, Prophylactic indomethacin, PDA, and Inotropes use) analyses were performed. The primary outcome was a composite of death and/or severe brain injury on cranial ultrasound using a validated classification. RESULTS: 181 neonates studied (93 before and 88 after). The rate and adjusted odds of death and/or severe brain injury reduced significantly post intervention (30% vs 15%) and (AOR 0.36, 95%CI, 0.15-0.85, P = 0.02) respectively. CONCLUSION: Implementation of outreach education targeting neuroprotection can reduce acute brain injury in transported premature neonates.

Does respiratory syncytial virus subtype influences the severity of acute bronchiolitis in hospitalized infants?

Respiratory syncytial virus (RSV) subtypes A and B are present either simultaneously or alternate during yearly epidemics. It is still not clear whether clinical severity of acute bronchiolitis differs between the two subtypes. Reverse transcription polymerase chain reaction was used to subtype RSV in previously healthy infants hospitalized with RSV bronchiolitis during a winter epidemic. A severity index based on heart rate, respiratory rate, wheezing, difficulty in feeding and oxygen saturation was calculated upon admission. Infants infected with RSV subtype-A were found to have a significantly higher (more severe) clinical score than those infected with RSV-B. There was no statistically significant difference in duration of hospitalization or need of intensive care. Boys and infants younger than 3 months of age were also more severely affected than girls or older infants, respectively. These results support the notion that RSV-A-induced bronchiolitis is more severe than RSV-B-induced one, in agreement with the majority of previously published studies.

Rhinovirus infections and adenoidal hypertrophy: do they interact with atopy in children?

Modern diagnostic methods allow the evaluation of the connection between rhinoviruses and atopy. Recent studies suggest that rhinoviruses are present in the adenoids at higher titers than in other specific sites, after inoculation of nasal mucosa or conjunctiva in volunteers. Therefore, it is possible that they might be responsible for specific local changes, while such changes may be influenced by atopy. This review focuses on the interactions between rhinoviral infection, the host's immune status and adenoidal disease.
