Ophthalmia neonatorum.

Area of Science:

• Neonatal ophthalmology
• Infectious diseases in newborns
• Microbiology of neonatal infections

Background:

• Neonatal conjunctivitis, or ophthalmia neonatorum, is a significant concern in newborn care.
• Understanding the etiological agents and risk factors is crucial for effective prevention and treatment strategies.
• Previous studies highlight varying prevalence and causative organisms globally.

Purpose of the Study:

• To determine the incidence of ophthalmia neonatorum in newborns at a specific medical center.
• To identify the predominant microorganisms responsible for neonatal conjunctivitis in the study population.
• To assess potential associated maternal and neonatal risk factors.

Main Methods:

• An observational study conducted at the Mother and Child Health (MCH) Center, Pakistan Institute of Medical Sciences (PIMS), Islamabad.
• Inclusion of all 1010 babies born during November 2008.
• Clinical examination for conjunctivitis on multiple days post-birth, with conjunctival swabs for Gram staining and culture from affected infants. Statistical analysis using chi-square test.

Main Results:

• A conjunctivitis incidence of 17% was observed among the 1010 neonates.
• Staphylococcus aureus was identified as the most frequent causative organism, accounting for 65% of positive cultures.
• Meconium-stained liquor and cesarean section were significantly associated with conjunctivitis (p=0.004 and p<0.001, respectively). No cases of gonococcal infection were detected.

Conclusions:

• The study reveals a high frequency of neonatal conjunctivitis in the studied population.
• Staphylococcus aureus is the primary etiological agent, suggesting a need for targeted interventions.
• Poor hygienic conditions and practices are implicated as potential significant risk factors in the Pakistani context.
