Invasive painful procedures affected regular HC growth and short-term cognitive scores in preterm infants in the first year of life.

BackgroundChest tube drainage and mechanical ventilation are effective treatment of symptomatic pneumothorax (PTX), but the best management of persistent (> 7 days) PTX is unknown.Case presentationWe 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.ConclusionsOverall, 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.

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.

Pyomyositis (PM) is an uncommon primary skeletal muscle infection caused mainly by Staphylococcus aureus that is characterized by single or multiple intramuscular abscess formation. In our ward, between 2013 and 2015, three children (two females and one male) aged from 2 to 12 years were diagnosed and treated for PM. Patients' medical records and imaging studies were examined retrospectively. All patients, otherwise healthy, complained of limp, fever, and severe lower limb pain. Skin scratch lesions were detected in two cases; one of them showed an edematous appearance of the affected area. Multifocal bilateral abscesses of gemini and gastrocnemius were detected in the youngest patient; right obturator and iliac muscles were affected in the second patient; and right gluteus and pyriform muscles were involved in the third patient. All patients showed elevated acute phase reactants and had normal serum creatinine kinase levels. Blood cultures and polymerase chain reaction (PCR) investigations were negative in all cases. Magnetic resonance imaging (MRI) findings included muscle enlargement, deep fascia, high signal in subcutaneous tissues, and postgadolinium abscess formation. No patient required surgical or percutaneous drainage. All three were treated conservatively with intravenous oxacillin, associated with ceftriaxone in the first patient and ceftazidime in the other two, followed by oral antibiotic therapy for a period ranging from 5 to 6 weeks. Pyomyositis must be considered as an unusual cause of limp in children of all ages. When promptly diagnosed and adequately treated, it has a favorable outcome without relapses or sequelae as occurred in all our patients.

BackgroundWe 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.MethodsWe 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).ResultsWe 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.ConclusionsUnexpected 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.
