Three-Dimensional Printed Model and Virtual Reconstruction: An Extra Tool for Pediatric Solid Tumors Surgery.

 Three-dimensional (3D) technology is increasingly applied for planning challenging surgical interventions. We report our experience using 3D printing and virtual reconstruction for surgical planning of complex tumor resections in children.  Data were obtained from preoperative magnetic resonance.

[Quality of life and long term results in Hirschsprung's disease].

Introduction: The most frequent long term side effects of Hirschsprung's disease (HD) surgery are obstructive problems and fecal incontinence. In this study, we analyse long term functional results of the two most used surgical techniques (Duhamel-D- and De la Torre-dlT-) from the patient's point of view, through quality of life and functionality questionnaires.

Methods: We selected short segment HD patients ≥ 4 years) that were operated in our unit from 1996 until 2011.

[Functional results of Hirschsprung's disease patients after Duhamel and De la Torre procedures].

Introduction: Long term results of different surgical techniques in Hirschsprung's Disease (HD) are contradictory. There are still no long term large or multicentric reports about functional results of De la Torre technique. We have studied the mid term functional results of the patients operated on Duhamel (D) and De la Torre (dlT) pull-through procedures.

[Rhabdomyomatous mesenchymal hamartoma].

Rhabdomyomatous mesenchymal hamartoma is a rare congenital lesion which consists of randomly arranged striated muscle fibers interspersed with mesenchymal elements. We describe the clinical and histopathological features of a rhabdomyomatous mesenchymal hamartoma in a one year-old patient presenting a bilobulated lesion in the mid-cervical line. No associated congenital malformations were observed.

Analysis of postfire vegetation dynamics of Mediterranean shrub species based on terrestrial and NDVI data.

The present study offers an analysis of regeneration patterns and diversity dynamics after a wildfire, which occurred in 1993 and affected about 7000 ha in southern Spain. The aim of the work was to analyze the rule in the succession of shrub species after fire, relating it to the changes registered in the Normalized Difference Vegetation Index (NDVI). Fractional vegetation cover was recorded from permanent plots in 2000 and 2005.

Genetic variation in the endemic and endangered Rosmarinus tomentosus Huber-Morath & Maire (Labiatae) using RAPD markers. Random amplified polymorphic DNA.

Rosmarinus tomentosus Huber-Morath & Maire, an endemic species of southern Spain, is critically endangered as a consequence of habitat destruction by anthropogenic activities. Random amplified polymorphic DNA (RAPD) markers were used for initial evaluation of genetic variation in this species; among zones, among populations (within zones and independently of zones), and among individuals (within populations and zones). The eight primers used to study five populations provided 126 reliable bands, of which 109 (86%) were polymorphic.

[Median raphe cysts of the perineum in childhood].

Median raphe cysts of the perineum are uncommon congenital lesions. Congenital lesions rarely encountered in daily clinical practice. Their diagnosis in childhood is particularly rare.

[Clinical response of different colonic segments to chemical denervation: an experimental study].

An experimental study in rats with chemical myenteric plexus destruction of different segments of large intestine is presented. Forty Wistar rats weighing 200-250 g were used. Four groups of ten animals each were made.

[Efficacy of extramucosal myotomy in an experimental model of intramural colonic obstruction. An experimental study in rats].

An experimental study over the efficacy of myotomy in the treatment of intramural colon obstruction is presented. Forty Wistar rats were used. Four groups were made with ten animals each: Group I: control; Group II: myenteric denervation of four cm segment of transverse colon; Group III: myenteric denervation of 4 cm segment of transverse colon and myotomy; Group IV: myotomy of segment of transverse colon.

[Neoformation of intestinal mucosa on dura mater patches. Application in the surgical treatment of short bowel syndrome. Experimental study in rats].

The creation of intestinal neomucosa on grafts or materials implanted in the intestinal wall is one of the therapeutic procedures that has been tested in the short bowel syndrome. This paper presents the results obtained after intestinal implanting lyophilised dural patches in an experimental model of massive intestinal resection in rats. Data were contrasted with those of a control group subjected to massive resection without patches.

[The surgical treatment of the short bowel syndrome by creating reservoir pouches. An experimental study on rats].

Intestinal pouches are one of the techniques for the surgical treatment of the short bowel syndrome. In a experimental study with rats, the influence of the intestinal pouches in a model of 85-90% small bowel resection are investigated. The pouches improve the transit time of the resected animal.

[Acute acalculous cholecystitis secondary to immersion asphyxia. Implications in organ donation].

A case of acute acalculous cholecystitis in a two year-old girl that undergone drowning in sweet water is reported. Cerebral death was diagnosed and the organs donation was authorized. A biliary peritonitis secondary to gallbladder perforation was met during organs extraction.

[Participation of the colon in the compensatory process after massive intestinal resection. An experimental study in rats].

The colon participation in the adaptation process after massive intestinal resection (R.I.M.

[Segmentary agenesis of the intestinal muscle layer: a rare cause of intestinal obstruction. A case report].

A very rare case of intestinal obstruction due to segmental agenesis of musculature of the small intestine is presented. In reviewing the literature, only nine cases of this entity has been published. Generally, the clinical evolution make necessary to perform several laparotomies, but the diagnosis is made by pathological findings.

[The neoformation of intestinal mucosa on dura mater patches. An experimental study in rats].

The technics of growing of small bowel neomucosa is one of the possible surgical therapies for the treatment of the short bowel syndrome. We carried out an experimental study in rats implanting patches and tubes of dura mater in the antimesenteric border of intestine. The growth of normal neomucosa is demonstrated.
