Pneumonia, Neonatal:
View cases of neonatal pneumonia
Clinical:
Neonatal pneumonia is defined as pulmonary infection occuring in the first 28 days of life [1]. The infection may be acquired in utero, during passage through the birth canal. The infection may be acquired as an ascending vaginal infection/placental infection or via contamination by maternal perineal flora at birth. Prolonged labor and premature rupture of the membranes increase the risk for infection.The most common pathogen is group B Strep [1]. Other organisms include S. aureus, or E. coli; and also viral (Chlamydia, Herpes).
X-ray:
CXR demonstrates radiating perihilar streaks with coarse, patchy parenchymal infiltrates. Diffuse hazy lungs is another form of presentation which is seen in nearly 50% of cases and may appear identical to respiratory distress syndrome (RDS). The presence of a pleural effusion is noted in about two-thirds of cases, but this finding is rare in RDS.REFERENCES:
