Purpose: To investigate the effectiveness and safety of a custom-made iris prosthetic device used to reduce photic symptoms in patients with congenital aniridia.
Setting: Cincinnati Eye Institute, Cincinnati, Ohio, USA.
Design: Retrospective single-surgeon case series.
Methods: The charts of all eyes of patients diagnosed with congenital aniridia syndrome who underwent implantation of the custom-made iris prosthesis at the setting institution between 2008 and 2018 were reviewed. Eyes with more than 6 months of follow-up were included in evaluation. Charts were carefully reviewed for comorbid conditions, interventions, and outcomes.
Results: Ninety-six eyes of 50 patients were included in the study. Subjective reduction in photophobia and glare was reported in 95.7% and 95.2% of cases, respectively. The incidence of aniridia fibrosis syndrome (AFS) in this study (3.1%; 95% confidence interval, 0.6%-8.9%) was similar to previous studies in the literature.
Conclusions: The custom-made iris prosthesis was an effective and safe option to reduce photic symptoms in patients with congenital aniridia. The custom, flexible iris implant does not appear to alter the risk for AFS. These highly complex eyes with significant comorbid pathologies demand an individualized approach and careful long-term follow-up.

Background: Central nervous system tumors (CNSTs) represent a significant oncological challenge in pediatric populations, particularly in developing regions where access to diagnostic and therapeutic resources is limited.
Methods: This research investigates the epidemiology, histological classifications, and survival outcomes of CNST in a cohort of pediatric patients aged 0 to 19 years within a 25-year retrospective study at the Civil Hospital of Guadalajara, Mexico, from 1999 to 2024.
Results: Data was analyzed from 273 patients who met inclusion criteria, revealing a higher incidence in males (51.

Background: A giant encephalocele associated with Chiari malformation is a rare congenital anomaly from a cephalad neural tube defect. Early prenatal diagnosis and parental counseling are essential; as early surgical intervention can improve outcomes.
Methods: Between 2010 and 2023, twenty-seven newborns out of 43,815 delivered at our institution were diagnosed with encephaloceles, including seven cases of giant encephalocele associated with Chiari malformation type III.

Objective: To test whether an artificial intelligence (AI) deep neural network (DNN)-derived analysis of the 12-lead electrocardiogram (ECG) can distinguish patients with long QT syndrome (LQTS) from those with acquired QT prolongation.
Methods: The study cohort included all patients with genetically confirmed LQTS evaluated in the Windland Smith Rice Genetic Heart Rhythm Clinic and controls from Mayo Clinic's ECG data vault comprising more than 2.5 million patients.

Severe early-onset scoliosis (EOS) can be addressed by different growth-friendly approaches, although the indications of each technique remain controversial. The aim of this study was to compare, in a large series of patients, the potential and limitations of the different distraction-based surgical techniques to establish the most suitable surgical approach to treat EOS. We conducted a retrospective observational cohort study evaluating 62 EOS cases treated between January 2002 and December 2021 with a traditional growing rod (TGR), a magnetically controlled growing rod (MCGR) and vertical expandable prosthesis titanium ribs (VEPTR) at IRCSS Istituto Ortopedico Rizzoli, Bologna, Italy.
