[Our experience with sirolimus for the treatment of complicated vascular anomalies].

Aim Of The Study: mTOR inhibitors are being used to treat complex vascular anomalies (VA) without response to conventional treatments. We report our results in pediatric patients treated with sirolimus.

Methods: Retrospective review of patients treated with sirolimus between 2014 and 2017, analyzing vascular anomaly type, treatment response and complications.

[Neonatal use of propranolol for segmental facial hemangiomas].

Introduction: Segmental cervico facial hemangiomas are defined as those longer than 5 cm, affecting a specific facial area. These lesions can be eventually associated with the PHACE syndrome. Our aim is to propose neonatal treatment with propranolol, showing its efficacy/safety, given the scarce evidence on its neonatal use.

[Neonatal surgical site infection: multicentric survey on prophylactic measures].

Objectives: Surgical site infection (SSI) has a considerable impact on neonatal morbidity. There are known risk factors such type of surgery (clean/contaminated), prematurity, surgical length, hypoalbuminemia, previous infection, prolonged mechanical ventilation, and so on. Many perioperative factors have not been studied, opposite to adults.

[Mesenteric cysts in children].

Objectives: Mesenteric cysts (MC) are benign cystic tumors that grow within mesentery or omentum tissue. We have reviewed the cases of MC reported and operated on in our centre.

Material And Methods: Retrospective review of clinical records of MC cases during the period 2002-2012 RESULTS: A total of 7 patients were found.
