Necrotic Lesions Following Elective Urological Surgery in an Infant.

 An 11-month-old female infant presented on the first postoperative (PO) day following an elective pyeloplasty, a dark bluish erythema of her lumbotomy wound, plus a satellite lesion of the same characteristics. Fever and sepsis developed, and despite broad spectrum antibiotics (meropenem and vancomycin) were started, a diagnosis of necrotizing soft-tissue infection (NSTI or necrotizing fasciitis) was established. Surgical debridement of both lesions was performed on day 3 PO, and a surgical contamination (ring retractor blade) was suspected, due to the particular geography of the lesion.

Benign Scrotal Tumor in a Pediatric Patient: Epididymal Cyst.

A pediatric patient of 12 years consulted for a left scrotal mass of 2 months of evolution. After suspecting a cystic content due to positive transillumination, on ultrasonography a scrotal cyst separated from the testis, of 5 cm in its maximum length, was confirmed. Due to size, parental anxiety, and the referred short evolution, excision was decided.

[Correlation between pneumoperitoneum and surgical findings and morbidity and mortality in newborns with necrotising enterocolitis].

Introduction: Surgical intervention in necrotising enterocolitis (NEC) is correct when there is intestinal gangrene. This is evident when gangrene produces perforation and pneumoperitoneum, with this being the only universally accepted radiological indication for the surgical intervention of NEC.

Objective: To perform an analysis on patients with surgically managed NEC, including determining how the decision to intervene is reached, the outcomes, and if patients with perforation had a pneumoperitoneum.

Introduction: Neonatal surgical wound infection occurs in almost 50% of neonatal procedures. It increases the rates of morbimortality in neonatal units. There is no guidelines about prevention of wound infection in neonatal surgery.

Renal Trauma in Pediatrics: A Current Review.

Children are at increased risk of renal injuries from blunt trauma. Four-phase computed tomography with intravenous contrast (noncontrast, arterial, nephrographic, and pyelographic phases) is the choice for initial imaging, although ultrasonography might also be used in children with minimal symptoms. The American Association for the Surgery of Trauma developed the known system for renal injury grading, which was modified in 2011.

[Functional and aesthetic evaluation of sacrococcygeal teratomas. Not everything ends with surgery].

Introduction: Sacrococcygeal teratoma is the most common solid neonatal tumour. The improvement in survival has meant that postoperative sequelae can be diagnosed and treated. The aim of this article is to evaluate the long-term outcomes of patients treated in our centre.

Migration of a ventriculoperitoneal shunt catheter through the processus vaginalis in infants: how serious inguinal hernia and hydrocele might be.

Migration of the catheter tip of a ventriculoperitoneal shunt (VPS) through a patent processus vaginalis (PV) has seldom being reported. In this series, we analyzed all cases of inguinoscrotal migration of an VPS catheter at our center. Between 1975 and 2015, 295 VPS insertions were performed.

[Management protocol in gastroschisis].

Aim: There are two classical managements in gastroschisis: primary or delayed closure. From 2007 on, a multidisciplinary approach protocol based in preterm caesarean delivery at 34-35th gestational age (in order to minimize peel injury) plus primary closure is followed in our institution. Prior to this, term delivery, either by caesarean section or not, was the rule.

[Use of ultrasound for placement of central venous catheters in pediatrics: results of a national survey].

Objectives: To study the variability of techniques used for vascular access of central venous devices, totally implanted and external tunneled, as well as polling the use of ultrasound by pediatric surgeons in Spain.

[Ultrasound markers in the follow up of pyeloplasty].

Introduction: There are few studies on the long term follow up of pyeloplasty. Is there a residual pelvis dilatation in all successful procedures? How is the long term evolution of the ecographic parameters and measures postoperatively (PO)?

Patients And Methods: We reviewed all successful Anderson-Hynes pyeloplasties performed on obstructed renal pelvis with an anterio-posterior diameter >15 mm during 2001-2010. Ultrasound controls were made at 3 and 6 months postoperatively and then yearly afterwards.

[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.

Dysfunctional Voiding in Pediatrics: A Review of Pathophysiology and Current Treatment Modalities.

In Dysfunctional Voiding (DV), the external urethral sphincter or pelvic diaphragm (consisting of striated muscle) contracts during voiding, contrary to normal physiological mechanism. In Flowmetry plus pelvic Electromyography (EMG), the perineal surface electrodes will show a persistent activity during voiding. The cause is believed to be the persistence of an immature bladder control.
