Objective: While the association of a syrinx with a tethered spinal cord in the context of VACTERL (vertebral defects [V], imperforate anus or anal atresia [A], cardiac malformations [C], tracheoesophageal defects [T] with or without esophageal atresia [E], renal anomalies [R], and limb defects [L]) association is known, the incidence of idiopathic syrinxes among these patients has not previously been reported. The authors aimed to characterize the incidence of syrinxes and the pattern of congenital anomalies in pediatric patients with VACTERL association, with a specific focus on the presence of idiopathic syrinxes in this population.

Methods: An institutional database was retrospectively queried for all pediatric patients with VACTERL association.

Turner syndrome (TS) is a genetic condition in phenotypic females in which the individual has 1 intact X chromosome and the second sex chromosome is absent or structurally altered Components of Y chromosome (eg, 45,X/46,XY) have been found in 5%-15% of patients with TS; these patients are often referred to as having "Turner syndrome with Y" (TS+Y). The presence of Y chromosome material increases risk for development of gonadal tumors. Historically, prophylactic gonadectomy has been recommended in this population to prevent malignancy, and patients were presumed infertile due to the presence of streak gonads with no germ cells (GCs).

  • The study aimed to assess the impact of the COVID-19 pandemic on hypertension awareness and treatment in Greece, analyzing data collected in 2019 and 2022 during the May Measurement Month (MMM) initiative.
  • Data from over 12,000 adults revealed consistent hypertension prevalence rates (around 41-43%) before and after the pandemic, but an increase in undiagnosed cases was observed, rising from 21.3% to 27.5%.
  • The findings suggest that while the overall prevalence of hypertension remained stable, there is a pressing need for improved national strategies to detect and manage hypertension effectively in Greece, especially post-pandemic.

Introduction: Pediatric patients with lower urinary tract dysfunction (LUTD) experience a variety of medical and psychosocial concerns that can negatively impact their clinical management and quality of life. When initially described by Drs Hinman and Baumann, patients with a form of severe LUTD, later dubbed Hinman syndrome, were characterized as having a "general attitude of being failures." While this mention was noteworthy as it incorporated an understanding of the interplay between psychological factors and urologic conditions, there have been delays in implementing psychological intervention as a standard of care in patients with LUTD broadly, and perhaps too keen of a focus on youth diagnosed with Hinman syndrome specifically.

Objectives: Brain-limited pathogenic somatic variants are associated with focal pediatric epilepsy, but reliance on resected brain tissue samples has limited our ability to correlate epileptiform activity with abnormal molecular pathology. We aimed to identify the pathogenic variant and map variant allele fractions (VAFs) across an abnormal region of epileptogenic brain in a patient who underwent stereoelectroencephalography (sEEG) and subsequent motor-sparing left frontal disconnection.

Methods: We extracted genomic DNA from peripheral blood, brain tissue resected from peri-sEEG electrode regions, and microbulk brain tissue adherent to sEEG electrodes.

Establishing an early and accurate genetic diagnosis among patients with differences of sex development (DSD) is crucial in guiding the complex medical and psychosocial care they require. Genetic testing routinely utilized in clinical practice for this population is predicated upon physical exam findings and biochemical and endocrine profiling. This approach, however, is inefficient and unstandardized.
