Outcomes of cases of prenatally-diagnosed congenital pulmonary airway malformation / Desfechos de casos de malformação das vias respiratórias diagnosticados no pré-natal

Abstract Objective To evaluate the outcomes of cases of prenatally-diagnosed congenital pulmonary airway malformation (CPAM). Methods We retrospectively evaluated cases of prenatally-diagnosed CPAM between 2004 and 2018. Ultrasonographic features such as visualization of a fetal lung mass and heterogeneous pulmonary parenchyma were used for CPAM diagnosis. Prenatal and postnatal findings were compared in terms of accuracy regarding the CPAM diagnosis. Results The sample consisted of 27 cases. There were four cases in which the patients opted for the termination of pregnancy due to the severity of the lesion. A total of 23 neonates were delivered, and CPAM was confirmed in 15 cases. Themedian gestational age at delivery was 37 weeks (28-40 weeks) and the mean birth weight was 2,776 g. There were two neonatal deaths, one due to pneumothorax, and the other due to hypoplastic left heart syndrome (HLHS). A total of five patients with respiratory problems were operated in the postpartum period. There were eight misdiagnosis: bronchopulmonary sequestration (five cases), congenital lobar emphysema (two cases), and congenital diaphragm hernia (one case). Conclusion A precise postnatal diagnosis is very important to organize the proper management of the pregnancies with fetuses with CPAM. The positive predictive value of the prenatal diagnosis of CPAM via ultrasonography is of 70.3%. The differential diagnosis of CPAM may be prolonged to the postpartum period in some cases.

Administración oral accidental de povidona yodada a un neonato: a propósito de un caso / Accidental oral administration of povidone iodine in a newborn: Case report

Las soluciones yodadas se utilizan ampliamente como antiséptico para el tratamiento y la prevención de infecciones en las heridas. La povidona yodada, una de las soluciones yodadas de aplicación tópica que más se encuentra en los botiquines de emergencia, podría producir anomalías graves, como disfunción tiroidea. La intoxicación por povidona yodada es poco frecuente; entre los efectos notificados previamente se incluyen complicaciones del uso tópico durante procedimientos quirúrgicos. Se describe el caso de un neonato que recibió povidona yodada por vía oral accidentalmente, sin signos ni síntomas de toxicidad después de la ingesta.

Iodine solutions are widely used as antiseptic for treating and preventing wound infections. Povidone iodine, one of the most common topical iodine solutions in emergency kits, can lead to several abnormalities as thyroid dysfunction. Povidone iodine poisoning is unusual and previously reported effects are mainly complications of topical usage during surgical procedures. Here we present the case of a newborn that was accidentally given oral povidone iodine, showing no signs or symptoms of toxicity after ingestion.

Vascular endothelial growth factor levels in newborns with meconium stained amniotic fluid.

OBJECTIVE: The effects of meconium-stained amniotic fluid (MSAF) on cord blood vascular endothelial growth factor (VEGF) levels have not been explored. The aim of this study was to verify whether MSAF influences cord blood VEGF levels in healthy term neonates and we can use cord blood VEGF levels in infants with MSAF as an indicator of fetal distress. METHODS: Using an enzyme-linked immunosorbent assay double sandwich method, plasma VEGF levels were determined in 18 healthy term neonates with MSAF and in 16 healthy term neonates without MSAF. RESULTS: VEGF plasma levels were not significantly different between healthy term neonates with or without MSAF. CONCLUSION: Intrauterine meconium passage could not affect VEGF levels on cord blood in term newborn infants and VEGF level may not be used as an indicator of fetal distress in infants with MSAF.

Fibrin glue for persistent pneumothorax in an extremely low birth weight infant.

Pleurodesis with fibrin glue has been used to treat bronchopleural fistulas and persistent air leaks in adults and neonates. We report successful use of fibrin glue in an extremely premature infant to seal a pneumothorax that had persisted for more than one week despite high-frequency ventilation.
