Purpose: To better define the overall performance of the current radiomics-based models for the discrimination of pediatric posterior fossa tumors.
Methods: A comprehensive literature search of the databases PubMed, Ovid MEDLINE, Ovid EMBASE, Web of Science, and Scopus was designed and conducted by an experienced librarian. We estimated overall sensitivity (SEN) and specificity (SPE). Event rates were pooled across studies using a random-effects meta-analysis, and the χ test was performed to assess the heterogeneity.
Results: Overall SEN and SPE for differentiation between MB, PA, and EP were found to be promising, with SEN values of 93% (95% CI = 0.88-0.96), 83% (95% CI = 0.66-0.93), and 85% (95% CI = 0.71-0.93), and corresponding SPE values of 87% (95% CI = 0.82-0.90), 95% (95% CI = 0.90-0.98) and 90% (95% CI = 0.84-0.94), respectively. For MB, there is a better trend for LR classifiers, while textural features are the most used and the best performing (ACC 96%). As for PA and EP, a synergistic employment of LR and NN classifiers, accompanied by geometrical or morphological features, demonstrated superior performance (ACC 94% and 96%, respectively).
Conclusions: The diagnostic performance is high, making radiomics a helpful method to discriminate these tumor types. In the forthcoming years, we expect even more precise models.

Intraoperative Hemodynamic Instability in Concomitant Pectus Excavatum and Scoliosis.

Patients with pectus excavatum and scoliosis can present a unique clinical challenge to operative correction. In patients with severe deformities, vascular structures in between the spine and sternum are at risk of compression, leading to hemodynamic collapse during correction of a spine deformity in the setting of unrepaired pectus excavatum. Careful consideration and multidisciplinary coordination should be used to determine the optimal timing, sequence, and operative approach in repair of the anterior and posterior deformities.

Tetralogy of Fallot with absent pulmonary valve and a nonconfluent left pulmonary artery is an uncommon combination usually associated with respiratory distress due to tracheobronchial compression by the aneurysmally dilated right pulmonary artery. Although application of the conventional technique is not feasible for this subset of patients, our novel "spiral plication" technique, wherein both the anterior and posterior walls of the dilated right pulmonary artery are resected in a spindle shape and plicated as if it is squeezed spirally, provides effective release of the obstructed airway concomitant with reconstruction of the left pulmonary artery confluence with growth potential.

Section of Pediatric Cardiac Surgery, Morgan Stanley Children's Hospital, New York, New York.
Among repairs for ventriculoarterial discordance, ventricular septal defect, and pulmonary stenosis, aortic root translocation (Nikaidoh operation) offers the most anatomic result. With a diminutive pulmonary annulus or hypoplastic left ventricular outflow tract, the distance gained posteriorly with aortic translocation is negligible. We developed the "hemi-Nikaidoh" procedure as an alternative.

Herein, we describe a 21-month-old girl with PHACE syndrome (posterior fossa hemangiomas, arterial lesions, cardiac anomalies/coarctation of the aorta, and eye anomalies) who presented with a tortuous extensive aortic arch aneurysm. As the maximum short diameter of the distal aortic arch aneurysm expanded rapidly from 21 mm to 25 mm in only 5 months, we performed extensive aortic arch reconstruction with interposition graft replacement through a left thoracotomy under partial cardiopulmonary bypass.

Background: Although Cochlear implantation (CI) is effective in restoring hearing for children with severe-to-profound sensorineural hearing loss, it may influence the middle ear mechanics, potentially causing an air-bone gap and altering middle ear stiffness, which is not detected by traditional 226 Hz tympanometry.
Aims/objectives: To investigate the effect of mastoidectomy posterior tympanotomy (MPTA) on wideband absorbance (WBA) in children with CI.
Materials And Methods: The study included 20 normal-hearing children (normal group) and 10 children with CIs who underwent MPTA (CI-MPTA group), aged 3-10 years.
