    Background Effective treatment and close monitoring of hypoglycemia in children with congenital hyperinsulinemic hypoglycemia (CHH) is vital to prevent brain damage. The current use of capillary sampling schedules does not provide a comprehensive assessment of glycemic status and fails to detect asymptomatic hypoglycemia episodes. Aim To investigate the efficacy and accuracy of a real-time continuous glucose monitoring system (RT-CGMS) in neonates with CHH. Methods A sensor connected to RT-CGMS was inserted into the newborn patients and maintained for at least 6 days during their stay in the hospital. We compared the readings of CGMS with capillary blood glucose values using Bland-Altman analysis. Results A total of 110 blood glucose values were compared to readings from the CGMS. All results were calculated and plotted for CGMS values at 0-4, 5-9, 10-14, 15-19, 20-24, and 25-29 min after capillary blood glucose sampling. CGMS readings were highly correlated with blood glucose values, especially during normoglycemia. In case of hypoglycemia, the mean difference between the CGMS and capillary glucose values was higher. Although the false positive rate for hypoglycemia was relatively high in CGMS, RT-CGMS may show some episodes of hypoglycemia earlier than blood measurement. Conclusion RT-CGMS is accurate during normoglycemia, and it can reduce the number of capillary blood samples in children with CHH. © 2021 Georg Thieme Verlag. All rights reserved.

    Introduction: The aim of the study was to analyse the clinical and demographic features of infants with gestational age (GA) of 32-37 weeks and birth weight (BW) of >1,500 g who developed treatment requiring retinopathy of prematurity (ROP). Methods: Data on the infants with a GA of 32-37 weeks and BW >1,500 g who developed treatment requiring ROP (TR-ROP) were collected retrospectively from the 33 ROP centres in Turkiye. GA, BW, type of hospital, neonatal intensive care units (NICUs) level, presence of an ophthalmologist and neonatologist in the same hospital, length of stay in NICU, duration of oxygen therapy, comorbidities, type of ROP, and timing for TR-ROP development were analysed. Results: A total of366 infants were included in the study. Mean GA and BW were 33 1 weeks and 1,896 316 g, respectively. Duration of hospitalization was 3-4 weeks in 46.8% of them. The first ROP examination was performed at postnatal 4-5 weeks in 80.3% of infants, which was significantly later in level 2 and lower NICUs and non-university clinics. At the first ROP examination, any stage of ROP was detected in 90.9% and TR-ROP was detected in 15.3% of the infants. The mean postnatal week of TR-ROP development was 6.16 2.04. Conclusion: Routine ROP screening thresholds need to be expanded in hospitals with suboptimal NICU conditions considering the development of TRROP in more mature and heavier preterm infants. The first ROP examination should be earlier than the fourth postnatal week. 2024 S. Karger AG, Basel. © 2024 S. Karger AG. All rights reserved.
