Optimal treatment of recurrent papillary thyroid carcinoma (PTC) in children remains controversial. We reviewed our experience with recurrent PTC to better identify children diagnosed with it. ⋯ Thyroid resection combined with selective use of radioactive iodine ablation is a safe and effective treatment for recurrent PTC in children. The best predictors of this recurrent disease are lymph node involvement and multiple thyroid nodules at presentation.

Nitrofen induces heart hypoplasia together with congenital diaphragmatic hernia (CDH) in rats. Intracellular oxidative stress might be one of the mechanisms of action of the teratogen, and vitamin A has been shown to reverse in part these effects when administered simultaneously or shortly after it. This study aims at testing the hypothesis that vitamin A and other antioxidant vitamins, such as E and C, could improve myocardial development even when administered late in gestation, a likely useful period for prenatal medication. ⋯ Antioxidant vitamins A, E, and C given late in gestation alleviate heart hypoplasia that accompanies CDH in the rat model. This timing suggests that the beneficial effects are exerted on the maturational phase of development.

The informed consent process for emergency surgery in children poses a challenge for pediatric surgeons because the child and his/her surrogates (usually parents) must make medical decisions in a relatively short period. The unique circumstances of a surgical emergency create potential barriers to achieving the central goals of the informed consent process, respect for patient autonomy and beneficence. The purpose of this review is to provide a practical guide for pediatric surgeons on the informed consent process as it applies to emergency surgery in pediatric patients. We will also discuss innovative methods of preoperative education that can be adopted in the emergency setting and highlight areas in which further research might help to improve this important aspect of surgical care.

Extracorporeal membrane oxygenation in infants with meconium aspiration syndrome: a decade of experience with venovenous ECMO.
Despite the emergence of new therapies for respiratory failure of the newborn with meconium aspiration syndrome (MAS), extracorporeal membrane oxygenation (ECMO) has a significant role as a rescue modality in these infants. Our objective was to compare the use of venovenous (VV) vs venoarterial (VA) ECMO in newborns with MAS who need ECMO and to ascertain the impact of new therapies in these infants during the last decade. We also evaluated how disease severity or time of ECMO initiation affected mortality and morbidity. ⋯ Venovenous ECMO is as reliable as VA ECMO in newborns with MAS in severe respiratory failure who need ECMO. Delay in ECMO initiation may result in prolonged mechanical ventilation and increased length of hospital stay. The emergence of new conventional therapies (NO, HFV, surfactant) and particularly increased experience enable sole use of VV ECMO with no significant change in survival in infants with MAS.

The management of an appendiceal mass remains controversial with 2 schools of thought; early surgical intervention vs nonoperative management with or without interval appendectomy. The aim is to determine the role and safety of early laparoscopic appendectomy (LA) in children with acute appendicitis presenting with an appendiceal mass. ⋯ Although early LA for an appendiceal mass is a technically demanding procedure, it can be performed safely in children with minimal morbidity and mortality. In an era where patients' demand for "key-hole" surgery is rising, early LA is a safe and viable option in the management of children with an appendiceal mass. It also offers the advantage of avoiding misdiagnoses and the need for a second hospitalization.
