Objectives:
To validate the web weight gain-based WINROP (weight, insulin-like growth factor I, neonatal, retinopathy of prematurity [ROP]) algorithm retrospectively to identify type 1 ROP in a Saudi cohort of premature infants.
Methods:
The records of preterm infants (>23 and <32 weeks gestation) born between August 2013 and October 2018, were reviewed. Birth weight, gestational age, and weekly weight measurements of the premature infants were entered online. Based on weekly weight gain, the WINROP algorithm alerted clinicians whether infants were at high-risk for vision-threatening type 1 ROP. Sensitivity, specificity, positive and negative predictive values were calculated.
Results:
The median gestational age of the infants at birth was 28 weeks, with median birth weight at 1085 g. Of the 175 infants included in the study, 13 (7.4%) developed type 1 ROP. WINROP positive alarm was triggered in 70.9% (124/175) of all infants and 100% (13/13) of those treated for type 1 ROP. The specificity of the algorithm was 31.5%. Positive predictive values was 10.5% and negative was 100%.
Conclusion:
The general WINROP sensitivity in identifying type 1 ROP was 100% similar to that reported in developed countries; however, its specificity was low at 31.5%. Tweaking of the algorithm based on the population may increase the specificity and promote the practical utility of this non-invasive screening tool for ophthalmologists and neonatologists in this population.

BackgroundAdenoidectomy is the most commonly performed pediatric operation worldwide and one of the most frequent otorhinolaryngological procedures. It is a safe procedure with a low risk of complications. However, after a successful adenoidectomy, few patients experience symptoms of nasal obstruction, suggestive of adenoid regrowth. Because of various risk factors, patients require a revision adenoidectomy. This study aimed to determine the incidence of revision adenoidectomy at King Abdulaziz University Hospital (KAUH). Moreover, we aimed to identify the characteristics and factors that present a risk of revision adenoidectomy in pediatric patients.
Materials and MethodsWe retrospectively reviewed the medical records of 680 pediatric patients (age below 18 years) of Saudi and non-Saudi descent who underwent a prior adenoidectomy with or without tonsillectomy, as well as those who underwent a revision adenoidectomy. The data from 2015 to 2018 were obtained from the hospital medical records using a data collection sheet.The data were entered on to a Microsoft excel sheet, and descriptive statistical analysis was performed using IBM SPSS software V21 (IBM Corp., Armonk, NY).
ResultsThe incidence of revision adenoidectomy at our center was 2.79%. We found significant relationships between comorbidities and revision adenoidectomy (p=0.014), initial adenoidectomy without tonsillectomy and revision adenoidectomy (p=0.001), and a young age at initial surgery and revision adenoidectomy. The mean age at initial adenoidectomy was 2.5 years (standard deviation [SD], ±0.607 years), whereas that at revision adenoidectomy was 1.89 years (SD, ±0.737 years). The mean interval between primary and revision adenoidectomies was 42.32 months (range, 9-86 months).
ConclusionThe incidence of revision adenoidectomy at KAUH was 2.79%. Moreover, only adenoidectomy without a tonsillectomy presented a high risk of adenoid regrowth necessitating a revision adenoidectomy. Therefore, we recommend counseling patients to undergo an adenoidectomy with tonsillectomy to reduce the risk of revision adenoidectomy.
