Retrospective analysis of 1028 ultrasound-guided central vascular access in neonates and children.

Background: The use of real-time ultrasound has become the standard of care for percutaneous central venous access and shown to decrease overall number of attempts and complication rates.

Material And Method: A retrospective analysis of a prospective database was done focusing on three types of central access: non-tunneled, tunneled, and implantable, placed via ultrasound-guided Brachiocephalic Vein (BCV) between January 2019 and January 2023. Data were recorded: gender, age, weight, side (left or right), number of puncture attempts, arterial puncture, change of operator or puncture side, and mechanical complications (pneumothorax and hemothorax).

Bacteremia associated with non-tunneled central venous catheters in children undergoing chronic hemodialysis.

Introduction. Central venous catheter (CVC)-related infection is the main complication observed in patients undergoing hemodialysis with this type of venous access. Objective.

Clinical Utility of Definitive Diagnostic Tests for Choledocholithiasis in Pediatric Patients with Mild Gallstone Pancreatitis.

Background: Gallstone pancreatitis was historically considered a risk factor for choledocholithiasis (CD). However, recent studies of adult patients evidenced a weak association between gallstone pancreatitis and CD. The aim of this study was to analyze this association in pediatric patients.

A Surgical and Clinical Approach to Persistent Müllerian Duct Syndrome: Laparoscopic, Histological, and Molecular Findings.

Background: Persistent müllerian duct syndrome (PMDS) is characterized by the persistence of müllerian duct derivatives in otherwise normally virilized 46,XY males. Biallelic mutations of the anti-müllerian hormone (AMH) and AMH receptor type 2 (AMHR2) genes lead to PMDS type 1 and 2, respectively.

Aim: The aims of the study were to report the clinical, hormonal, and genetic findings in a patient with PMDS and discuss surgical strategies to achieve successful orchidopexy.

In a Setting of Esophageal Replacement, Total Gastric Pull-Up has Fewer Complications than Partial Gastric Pull-Up.

Aim: The main indications for an esophageal replacement (ER) are unresolved complex esophageal atresia (EA) and caustic strictures (CS). The use of different organs for replacement has been described. When the stomach is chosen, there are two ways to do a gastric pull-up: a partial (PGP) or a total pull-up (TGP).

Development of a risk score for choledocholithiasis in pediatric patients.

Purpose: The prevalence of gallstones in children has increased over the last years. Choledocholithiasis (CD) is present in up to 30% of the cases. There is a scarcity of studies on the management of choledocholithiasis in children.

Umbilical arteriovenous malformation in a healthy neonate with umbilical hernia.

We describe the case of a neonate with an umbilical hernia and persistent wet umbilicus. Examination revealed a pulsatile umbilical cord with palpable thrill. Doppler ultrasound suspected umbilical arteriovenous malformation and contrast-enhanced computed tomography was performed leading to a definitive diagnosis.
