[Pediatric surgery 2.0].

New tools from the web are a complete breakthrough in management of information. The aim of this paper is to present different resources in a friendly way, with apps and examples in the different phases of the knowledge management for the paediatric surgeon: search, filter, reception, classification, sharing, collaborative work and publication. We are assisting to a real revolution on how to manage knowledge and information.

[Retrospective evaluation of carcinoid tumors of the appendix in children].

Carcinoids of the appendix are rare in children. Usually diagnosed incidentally on histologic investigation following appendectomy for acute apendicitis. To investigate the significance of the diagnosis of appendiceal carcinoid tumors in children, we conducted a retrospective study in our institution.

[Cystic adenomatoid malformation pulmonary: are we able to foresee its evolution?].

The congenital pulmonary malformation are a rare entity in pediatric age. Between of them, the cystic adenomatoid malformation (MAQ) is the most ferquent entity, followed by pulmonary sequestration (SP) and the most rare broncogenic cyst. As a consequence of ultrasound and fetal magnetic resonance we are abble to diagnose earlier this patology.

[Boix Ochoa's antireflux procedure returns patients to normalcy: 24 hour esophageal pH monitoring of 21 cases].

A great controversy exist concerning the surgical management of gastroesophageal reflux (GER). It is well known that Nissen procedure produces a hypercorrection of the gastroesophageal competency and often a "gas bloat syndrome". On the other hand, the Boix Ochoa's technique is more physiological but corrects GER allowing the persistence of a "radiological" reflux.

[Postoperative pain in children: its assessment and treatment. Introduction].

An explication of the phylogeny of pain and its consequences, the difficulties involved in its measurement and the need to eliminate, reduce or control it, but always considering that it is usually an indication of an organic malfunction. There is also a discussion of the importance of pain on the mind and the effect of the mind on the perception of pain.

[Septic arthritis in children].

A review was made of 15 cases of septic arthritis in children. 13 of these cases corresponded to purulent arthritis, one to tuberculous arthritis and one to brucellar arthritis. All of them received diagnostic punction.

[Rib actynomycosis].

A unusual case of rib actynomycosis, observed several months after surgery for acute appendicitis in a 11 year boy is reported. Surgical excision of the affected segment of rib had to be implemented with lyncomycin in order to obtain the cure. Laboratory data are consistent with the above mentioned diagnosis.

[Neonatal functional intestinal obstruction of unknown etiology (author's transl)].

Three cases of newborn intestinal obstruction without obvious organic cause are reported. Narrow left colon (Davis's syndrome), small colon, megacystis and intestinal hypoperistaltism (Berdon's syndrome) and segmental bowel dilatation (Swenson's syndrome) were the diagnoses. Through a review of the literature a possible interrelationship among these three clinical entities at the level of an abnormal myenteric plexus neuronal function is discussed.
