[Is experimental surgery necessary or essential in the training program of a pediatric surgeon?]. / ¿Es necesaria o imprescindible la cirugía experimental en el programa formativo de un cirujano pediátrico?

Many surgical procedures performed in pediatric surgery have a slow learning curve, the volume of patients and the existence of complex diseases that require extensive training and surgical skill, have taken our service to create a global training program of experimental surgery. This program based on the simulation and training invasive procedures in real anatomical models, aims to educate our residents in a global and efficiently way in order to obtain an improvement of technical training, and increased patient safety result of experience and expertise wined in the experimental animal. This paper presents the main features, objectives and results obtained with this training program and seeks to promote the incorporation of simulation programs in live animal as an essential part of the training of pediatric surgery resident.

[The "Heart Area" of Juan Canalejo Hospital Complex. A new approach to clinical management]. / El "área del corazón" del complejo hospitalario Juan Canalejo. Una nueva forma de gestión clínica.

In the first section, the needs and reasons that led to the undertaking of this project are explained. The project's objectives and operative strategies are listed. In the Material and Methods section, three basic aspects of the "Heart Area" are described: selection criteria of the "Area", its structure and function, and its foundation and development. In the Results section, we compare the activity undertaken in the "Area" to the situation present prior to its implementation, in relation to quality and costs.

[Ureteral hydronephrosis secondary to appendicular abscess]. / Ureterohidronefrosis secundaria a absceso apendicular.

OBJECTIVE: To report a case of ureterohydronephrosis secondary to an undiagnosed appendiceal abscess. METHODS/RESULTS: Herein we describe a case of a 4-year-old girl with right ureterohydronephrosis arising from extrinsic compression of the right ureter due to an undiagnosed appendiceal abscess. The patient was treated with intravenous antibiotics and the abscess was drained. Regular isotope and US assessments showed both the residual retroperitoneal fibrosis and renoureteral dilation had decreased. CONCLUSIONS: Acute appendicitis is still the most common cause of emergency abdominal operations in children. Although the symptoms are easily recognizable and generally lead to the correct diagnosis in most cases, the peculiarities of childhood can lead to errors in the diagnosis resulting in the complications reported herein. We emphasize the usefulness of ultrasound in the diagnosis and conservative treatment is advocated.
