Giant neonatal hydronephrosis of the upper pole of a complete duplicated renal system.

Ureteropelvic junction obstruction (UPJO) in the upper pole of a complete duplicated renal system is extremely rare. We report a case that was diagnosed prenatally and we review 10 cases published in the literature. Diagnoses of adrenal hematoma and cystic neuroblastoma were suspected on prenatal ultrasound, based on the severity of dilatation and the difficulty of identifying the exact origin of this anomaly.

Access to Top-Cited Emergency Care Articles (Published Between 2012 and 2016) Without Subscription.

Introduction: Unrestricted access to journal publications speeds research progress, productivity, and knowledge translation, which in turn develops and promotes the efficient dissemination of content. We describe access to the 500 most-cited emergency medicine (EM) articles (published between 2012 and 2016) in terms of publisher-based access (open access or subscription), alternate access routes (self-archived or author provided), and relative cost of access.

Methods: We used the Scopus database to identify the 500 most-cited EM articles published between 2012 and 2016.

Is contralateral inguinal exploration necessary in preterm girls undergoing inguinal hernia repair during the first months of life?

Background: To assess the need for contralateral surgical exploration in preterm girls with symptomatic unilateral inguinal hernia.

Methods: The medical data of girls operated for inguinal hernia between 2004 and 2016 in a single pediatric surgery center were retrospectively collected. Preterm girls operated for unilateral hernia before 6 months of life were selected (55/517 cases) to assess the incidence and risk factors for contralateral metachronous inguinal hernia (CMIH).

[Cystinuria in children: A report of 4 cases].

Cystinuria is an inherited autosomal-recessive disorder of renal reabsorption of the dibasic amino acids. It is the cause of about 6% of all kidney stones observed in children. Cystine is relatively insoluble at the physiological pH of urine.
