Bladder duplication in a patient with a persistent urogenital sinus: Case report and systematic review of the literature.

Bladder duplication (BD) is a rare malformation that is often associated to other anomalies. We report a newborn diagnosed with BD in the sagittal plane, associated to persistent urogenital sinus (UGS), given the opening of the vagina immediately below the bladder neck. It is the fourth time this association is reported.

Sarcopenia as a Prognostic Factor in Patients with Hepatoblastoma: Does It Influence Surgical Outcomes and Survival? Preliminary Retrospective Study.

Aim: Sarcopenia is associated with poor prognosis in adult oncologic patients, with little evidence of this association in pediatric population, including hepatoblastoma.

Methods: Retrospective study in patients with hepatoblastoma, divided into those with or without sarcopenia. Sarcopenia was assessed by measuring psoas muscle area (PMA) at L4-L5 level on the CT/MR and defined as z-score values ≤ 2.

Towards a standardized initial training program in experimental microsurgery for pediatric surgeons.

Objective: To describe a basic training program in microsurgery and to analyze the learning curve through the process, including improvement in operating times and functional outcome.

Materials And Methods: Our learning program included basic, transitional, and experimental models. The experimental model included tail vein cannulation, intestinal resection and anastomosis, dissection, division and anastomosis of the cava and aorta.

Sequential teratoma in pediatric patients: causation or coincidence?

We describe the unusual case of a female patient with a history of two mature teratomas non-correlated in terms of location and occurrence. A 12-year-old girl presented at our consultation as a result of a growing tumor in the hypogastric region, with no further clinical signs. She had undergone surgery neonatally due to a mature cystic sacrococcygeal teratoma, which was fully removed.
