Retinal detachment in a neonate with congenital chylothorax and purpura fulminans associated with the PAK2 genetic variant: A case report
Bibliographic record
Abstract
INTRODUCTION AND IMPORTANCE: A potential relationship between bilateral retinal detachment, chylothorax, and purpura fulminans in a female neonate with a PAK2 gene variant is not commonly reported. This emphasizes the significance of early ophthalmologic assessment in neonates with congenital chylothorax. CASE PRESENTATION: A full-term female infant weighing 2.775 kg was delivered by cesarean section due to breech presentation. Prenatal imaging revealed fetal bilateral pleural effusion, suggestive of chylothorax. The neonate developed respiratory distress and purpura fulminans after birth. The absence of the red reflex in the right eye prompted a detailed ophthalmologic examination using a portable slit lamp and an indirect ophthalmoscope. The right eye revealed an ectatic pupil with posterior synechia extending from approximately 6 o'clock to 9 o'clock. Fundus examination of both eyes revealed funnel retinal detachment with multiple chronic features. A small amount of retina was draped between 4 and 7 o'clock, which may have been attached. Further ophthalmologic investigation under anesthesia, using B-scan ultrasonography and intravenous fluorescein angiography, confirmed bilateral retinal detachment. Genetic investigations revealed a PAK2 c.1115A>T, p.(Asp372Val) variant. CLINICAL DISCUSSION: In addition to presenting our case report, we reviewed other recent case reports similar to ours. Retinal detachment and bilateral pleural effusions in neonates with Knobloch syndrome have been recently reported, but without purpura fulminans. Retinal detachment in neonates can result from both congenital and acquired conditions, and requires a thoughtful approach to establish the diagnosis and provide future counseling. CONCLUSION: Bilateral retinal detachment, chylothorax, and purpura fulminans in a neonate with a PAK2 genetic variant is uncommon. This case underscores the importance of early ophthalmologic assessment and genetic testing for both neonates and their family members.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
