Abstract
Osteoporosis-pseudoglioma syndrome (OPPG) is a rare disorder characterized by severe osteoporosis and vision impairment, due to mutations in the low-density lipoprotein receptor-related protein 5 (LRP5) gene. This autosomal recessive disorder is characterized by fractures, bone fragility, and pseudoglioma with blindness in infancy. Herein, we present a rare case of OPPG syndrome in an infant who, at 80 days of life (DOL), exhibited multiple fractures without any ophthalmic findings at the time of presentation. This is relatively earlier presentation of the symptoms as fractures are more commonly seen after two years of life.

Abstract
Background: Hyperbilirubinemia is the most common clinical abnormality in newborns during the first week of life. Phototherapy is the standard treatment but may cause complications, including hypocalcemia, a lesser-known yet significant adverse effect. This study investigated the impact of phototherapy on serum calcium levels in neonates with hyperbilirubinemia.
Methods: This observational study was conducted in the NICU of BYL and T.N. Medical College, Mumbai, over 12 months after ethical approval. We included 100 neonates (> 34 weeks gestational age) with hyperbilirubinemia receiving phototherapy. Serum calcium levels were measured before and after phototherapy, and neonates were monitored for clinical hypocalcemia. Data were recorded in a pre-formatted proforma and analyzed using SPSS version 27 (p <0.05 was considered statistically significant).
Results: The mean age of neonates was 3±1.2 days, the mean gestational age was 37±1.2 weeks, and the mean jaundice duration was 2.8±1.10 days. Median serum calcium levels decreased significantly from 8.6 mg/dL (8.49-8.61) pre-phototherapy to 7.35 mg/dL (7.33-7.50) post-phototherapy (p <0.001). Hypocalcemia (serum calcium ≤7 mg/dL) occurred in 16% of neonates, with 60% exhibiting mild symptoms like jitteriness or irritability.
Conclusion: Phototherapy significantly reduces serum calcium levels in jaundiced neonates, with a notable incidence of hypocalcemia. Clinicians should monitor calcium levels and watch for symptoms during phototherapy to prevent complications. Further studies are needed to establish preventive strategies.
