Fibrin glue pleurodesis for pneumothorax in extremely preterm infants: A case report and literature review

Abstract Background Chest tube drainage and mechanical ventilation are effective treatment of symptomatic pneumothorax (PTX), but the best management of persistent (> 7 days) PTX is unknown. Case presentation We reported a case of successful fibrin glue pleurodesis of persistent PTX in an extremely preterm infant without adverse effects. We discussed previous literature on this treatment. Conclusions Overall, the twelve reported cases suggest that persistent PTX sealing with fibrin glue can represent a simple, quick, and effective treatment whose possible reported adverse effects are transient and do not cause permanent sequelae. Thus, fibrin glue pleurodesis might be considered a suitable therapeutic tool in very preterm infant with persistent PTX

Unexpected episodes of cyanosis in late preterm and term neonates prompted admission to a neonatal care unit

Abstract Background We studied late preterm and term infants who were admitted to our neonatal care unit in a tertiary hospital for unexpected episodes of cyanosis that occurred during rooming-in for evaluation of their frequency, most frequent associated diseases, and documentation of the diagnostic clinical approach. Methods We carried out a retrospective study of infants with a gestational age ≥35 weeks who were admitted from the nursery with the diagnosis of cyanosis from January 2009 to December 2016. Exclusion criteria were the occurrence of acrocyanosis and the diagnosis of sudden unexpected postnatal collapse (SUPC). Results We studied 49 infants with a mean gestational age of 38 ± 2 weeks. The frequency of admission for cyanosis was 1.8/1000 live births and was similar (p = 0.167) in late preterm and term infants. The majority of episodes occurred during the first 24 h of life (57%). Only 16 infants (33%) were discharged with a diagnosis, that was mostly (n = 5;10%) gastro-esophageal reflux. Conclusions Unexpected episodes of cyanosis caused admission of 1.8/1000 live births to the neonatal care unit without differences between late preterm and term infants. These episodes occurred mainly during the first day of life and infants were mostly discharged without a known diagnosis

Transient Neonatal Diabetes Mellitus in a Very Preterm Infant due to ABCC8 Mutation

Neonatal diabetes mellitus (NDM) is a monogenic form of diabetes occurring within 6 months from birth. NDM can be permanent or transient (TNDM). We report the case of a preterm infant with TNDM due to an ABCC8 mutation identified by next-generation sequencing. The pancreatic adenosine triphosphate (ATP)-sensitive K+ (K-ATP) channel is a key regulator of insulin secretion. Gain-of-function mutations in the genes encoding the Kir6.2 (KCNJ11) and SUR1 (ABCC8) subunits of the channel cause neonatal diabetes. The patient was successfully managed with insulin lispro at a 1:100 dilution, drawn up in an insulin pen injector with a 4-mm needle. The insulin lispro dilution allowed administration of the exact insulin doses, obtaining a good glycemic control and minimizing the burden of injections. At 2 months, corrected age insulin doses were progressively decreased until discontinuation
