This study describes a new visual acuity test for preschool and exceptional children. It is independent of verbal responses, uses a forced-choice testing procedure, incorporates the psychometric design advantages of the Landolt ring, and can be administered at 3m (10 ft) in 5 to 7 minutes. The results support its construct validity in accurately measuring visual acuity levels and its clinical applicability for preschool and exceptional children.

Aims: To evaluate the impact of anthropometric and sociodemographic factors on dental caries and gingival health among children with special healthcare needs (SHCN).
Methods And Results: This cross-sectional study involved 108 children, aged 4-14 years, with congenital heart disease, childhood cancer, bleeding disorders, various syndromes, and multiple conditions. Caregivers completed a sociodemographic questionnaire, and children underwent dental examinations to assess caries, gingival health, and oral hygiene.
An exceptionally rare case of a diffuse midline glioma with concomitant H3.1 K27M and G34R mutations in the HIST1H3C (H3C3) gene.

Histone mutations (H3 K27M, H3 G34R/V) are molecular features defining subtypes of paediatric-type diffuse high-grade gliomas (HGG) (diffuse midline glioma (DMG), H3 K27-altered, diffuse hemispheric glioma (DHG), H3 G34-mutant). The WHO classification recognises in exceptional cases, these mutations co-occur. We report one such case of a 2-year-old female presenting with neurological symptoms; MRI imaging identified a brainstem lesion which was biopsied.

Article Synopsis
- Urinary tract infections (UTIs) in children are primarily caused by enterobacteria, but Streptococcus pneumoniae is a rare cause that can indicate underlying issues.
- A case study focused on a 2-year-old girl with recurrent UTIs, renal malformations, and a detected UTI caused by Streptococcus pneumoniae demonstrated the importance of thorough imaging studies for such cases.
- The findings highlight that UTIs from this atypical bacterium often correlate with serious renal-urological conditions, emphasizing the necessity for additional urinary tract evaluations in affected patients.

We propose a knowledge-enhanced electrocardiogram (ECG) diagnosis foundation model (KED) that utilizes large language models to incorporate domain-specific knowledge of ECG signals. This model is trained on 800,000 ECGs from nearly 160,000 unique patients. Despite being trained on single-center data, KED demonstrates exceptional zero-shot diagnosis performance across various regions, including different locales in China, the United States, and other regions.

Evading apoptosis fuels the aggressive nature of acute lymphoblastic leukemia (ALL). This study explored the potential roles of TNF-α, a pro-apoptotic cytokine, and TGF-β, a pro-proliferative factor, in the risk of developing ALL in Egyptian children. We investigated the TNF-α rs1800629 polymorphism and serum TGF-β levels in 100 ALL patients and 100 healthy controls.
