A Novel Report of Müllerian (Vaginal/Uterine) Agenesis in a Newborn Girl With LUMBAR Syndrome.
Pediatr Dermatol
January 2025
Division of Dermatology, Children's Mercy Kansas City, Kansas City, Missouri, USA.
LUMBAR syndrome is characterized by lower body segmental infantile hemangiomas, urogenital abnormalities/hemangioma ulceration, spinal cord malformations, bony deformities, anorectal malformations/arterial anomalies, and/or renal anomalies. Here we present an infant girl with LUMBAR syndrome who was also discovered to have Müllerian agenesis, defined as absent uterus or nonfunctional uterine remnants. While vaginal and uterine duplications are included among the diagnostic criteria for LUMBAR syndrome, this is the first case of associated Mullerian agenesis.

This study aimed to describe the morphological alterations that occur in the midgut and mesentery over time during the herniated phase of the midgut. The primary loop, a single hairpin-shaped loop, becomes recognizable at Carnegie stage (CS) 16. This loop projects toward the umbilical cord and subsequently gives rise to four secondary loops in the midgut of human embryos.

Pediatric Interventional Cardiology Unit, Autònoma de Barcelona University, Vall d'Hebron Hospital, Barcelona, Spain.
We describe a 12-year-old boy with agenesis of the intrahepatic segment of the inferior vena cava (a rare congenital anomaly) in whom an electrified coronary guidewire with electrocautery was used percutaneously to perforate and open the atretic segment, followed by stent implantation. This technique may be a safe and feasible option for paediatric patients, offering a therapeutic alternative for complex cardiac anatomies.

J Neurol Surg B Skull Base
February 2025
Department of Neurosurgery, All India Institute of Medical Sciences, Jodhpur, Rajasthan, India.
Instrumentation of C2 vertebra is considered the most difficult for young neurosurgeons and trainees due to its complex anatomical structures, variety of surgical approaches and techniques, and proximity to important neurovascular structures. Key points from a surgical perspective for midline posterior approach is described in the era of neuroradiological advancements. Computed tomography angiographies (CTAs) of a total of 92 patients were evaluated with special attention to the key findings for insertion of screws for craniovertebral junction (CVJ) fixations.

Department of Orthopaedics, Division of Pediatrics and Adolescent Orthopaedic Surgery and Division of Spine Surgery, Washington University School of Medicine, St. Louis, MO.
Introduction: Since the development of pedicle screw fixation in the spine, safe placement has remained a crucial component in maximizing patient outcomes and mitigating pedicle screw-related complications. The purpose of this study is to investigate the utility of pedicle tapping in identifying pedicle breaches.
Methods: A pediatric spine surgery database was queried to identify a consecutive series of patients who underwent spinal deformity surgery utilizing pedicle screw fixation between May 2019 and October 2022.
