Success Rate and Predicting Factors for Repeated High-Dose Intradetrusor Dysport Injections in Children With Neurogenic Bladder: A Retrospective Study.

Objectives: Evaluating the effectiveness and safety of repeated high-dose intradetrusor abobotulinumtoxin A (Dysport®) injections for the treatment of pediatric neurogenic bladders refractory to medications.

Design: Retrospective interventional study.

Participants: The cohort included 37 children (22 boys and 15 girls) of median age 9.

A comparative study between EMG uroflowmetry with and without a catheter in children.

Objectives: To evaluate the effect of urethral catheterization on the accuracy of EMG uroflowmetry in children with non-neurogenic voiding disorders during pressure-flow (PF) studies compared to the non-invasive EMG uroflowmetry test.

Methods: A retrospective study of children undergoing a urodynamic evaluation at our institution between 8/2018 and 7/2022 was employed. Urination curves and pelvic floor muscle activity were compared between PF studies and non-invasive EMG uroflowmetry test.

Disordered sequences of transcription factors regulate genomic binding by integrating diverse sequence grammars and interaction types.

Intrinsically disordered regions (IDRs) guide transcription factors (TFs) to their genomic binding sites, raising the question of how structure-lacking regions encode for complex binding patterns. We investigated this using the TF Gln3, revealing sets of IDR-embedded determinants that direct Gln3 binding to respective groups of functionally related promoters, and enable tuning binding preferences between environmental conditions, phospho-mimicking mutations, and orthologs. Through targeted mutations, we defined the role of short linear motifs (SLiMs) and co-binding TFs (Hap2) in stabilizing Gln3 at respiration-chain promoters, while providing evidence that Gln3 binding at nitrogen-associated promoters is encoded by the IDR amino-acid composition, independent of SLiMs or co-binding TFs.

Pediatric Age-Related Distribution of Calcium Oxalate Monohydrate and Calcium Oxalate Dihydrate in Urinary Tract Stones: Metabolic, Gender, and Ethnic Correlates.

Previous studies of pediatric urolithiasis have suggested possible associations between the relative proportions of calcium oxalate dihydrate (COD) and calcium oxalate monohydrate (COM) stones with age, gender, and ethnicity. This study aimed to investigate the composition and distribution of calcium oxalate (CaOx) stones according to these clinical factors and the metabolic correlates of the different subtypes in pediatric stone formers (PSFs). We retrospectively reviewed the database of all first-time stone formers between 2014 and 2019.

The accuracy of cystography under general anesthesia in children with vesicoureteral reflux.

Purpose: To examine the accuracy of cystography under general anesthesia in children with vesicoureteral reflux (VUR).

Materials And Methods: A prospective study of children who had VUR on cystography without general anesthesia (i.e.
