The use of high-flow nasal cannula (HFNC) therapy as respiratory support for preterm infants has increased rapidly worldwide. The evidence available for the use of HFNC is as an alternative to nasal continuous positive airway pressure (CPAP) and in particular to prevent postextubation failure. We report a case of tension pneumocephalus in a preterm infant as a complication during HFNC ventilation. Significant neurological impairment was detected and support was eventually withdrawn. Few cases of pneumocephalus as a complication of positive airway pressure have been reported in the neonatal period, and they all have been related to CPAP. This report reinforces the need to be aware of this rare but possible complication during HFNC therapy, as timely diagnosis and treatment can prevent neurological sequelae. We also stress the importance of paying close attention to flow rate, nasal cannula size and insertion, and mouth position, and of regularly checking insertion depth.

Following current recommendations for preventing retinopathy of prematurity (ROP) involves screening a large number of patients. We performed a prospective study to establish a useful screening system for ROP prediction and we have determined that measuring serum levels of IGF1 at week three and the presence of sepsis have a high predictive value for the subsequent development of ROP. A total of 145 premature newborn, with birthweight <1500 g and/or <32 weeks gestational age, were enrolled. 26.9% of them showed some form of retinopathy. A significant association was found between the development of retinopathy and each of the following variables: early gestational age, low birthweight, requiring mechanical ventilation, oxygen treatment, intracranial haemorrhage, sepsis during the first three weeks, bronchopulmonary dysplasia, the need for erythrocyte transfusion, erythropoietin treatment, and low levels of serum IGF1 in the third week. A multiple logistic regression analysis was used to obtain curves for the probability of developing ROP, based on the main factors linked with ROP, namely serum levels of IGF1 and presence of sepsis. Such preclinical screening has the ability to identify patients with high-risk of developing retinopathy and should lead to better prediction for ROP, while at the same time optimising the use of clinical resources, both human and material.

GOTGlutamate-oxaloacetate transaminase AIM Fetal blood contains higher concentrations of glutamate-oxaloacetate transaminase (GOT; a blood enzyme able to metabolize glutamate) than maternal blood. The aim of this study was to determine the relationship between GOT and glutamate levels in arterial blood samples from umbilical cord in control newborn infants and newborn infants with hypoxicischaemic insult and/or symptoms of hypoxia-ischemia after delivery.METHOD A total of 46 newborn infants (28 females, 18 males) were prospectively included in the study. Twenty-three infants (18 females, five males) were included as control participants and 23 (10 females, 13 males) were included as newborn infants at risk of adverse neurological outcome (defined as umbilical blood with pH <7.1). RESULTS Analysis of glutamate concentration and GOT activity in umbilical blood samplesshowed that newborn infants with pH <7.

Background:Umbilical cord hemangioma is very rare and may not be detected prenatally. However, it should be considered in differential diagnosis with other umbilical masses because it can cause significant morbidity.Methods:We report the case of a newborn referred with suspected omphalitis and umbilical hernia.Results:Physical examination showed an irreducible umbilical tumor, the size of olive, with dubious secretion. The initial suspected diagnosis was urachal or omphalomesenteric duct remnants. Abdominal ultrasound and magnetic resonance imaging showed an umbilical and a mesenteric mass. Tumor markers were negative. A definitive diagnosis of umbilical cord and intestinal hemangioma was established after surgical excision and histologic examination of the umbilical mass. Propranolol was prescribed due to the extent of the intestinal lesion.Conclusion:This report highlights the diagnostic challenges of hemangiomas in unusual locations. Apart from the rarity of these tumors, few tests are available to guide diagnosis, and surgery and histologic examination are generally required for a definitive diagnosis. Finally, it is essential to rule out associated malformations and hemangiomas in other locations.
