Introduction: Children with severe congenital absence of teeth present uncommon morphologies and therapeutic challenges. This study was designed to investigate the characteristic skeletal and dental features of this group.
Methods: A group of 28 children with at least 10 congenitally missing teeth (excluding third molars) was examined roentgenographically. The data were collected from their intraoral series or panoramic views and lateral cephalograms. The results of their cephalometric analyses were compared with classic cephalometric norms and with local population norms.
Results: Specific patterns of incisor, premolar, and third molar absence emerged. The cephalometric parameters of the children with severe absence differed from the classic norms in bimaxillary retrognathism, chin angle, and maxillary incisor inclination. These children differed from the Israeli norms in almost all parameters examined.
Conclusions: Patients with severe congenital absence of teeth have unique dental and skeletal patterns.

The Berlin Heart EXCOR is a pulsatile paracorporeal ventricular assist device (VAD) for neonates, infants, children and adults with congenital or acquired severe ventricular dysfunction. Berlin Heart EXCOR VADs are routinely used as either a bridge to a cardiac transplantation, or occasionally as a bridge to ventricular recovery. Our programmatic philosophy is to bridge neonates and infants with functionally univentricular ductal-dependent systemic circulation or functionally univentricular ductal-dependent pulmonary circulation who are at high risk for staged palliation because of important cardiac risk factors with a single-ventricle VAD (sVAD) as a bridge to a cardiac transplant.

Background: Ectopic thyroid tissue (ETT) is a rare congenital anomaly caused by the abnormal embryonic migration of thyroid tissue, leading to its presence outside its usual pretracheal location. This condition can lead to diagnostic challenges, especially when located within the airway, as it mimics other respiratory disorders such as asthma.
Case Presentation: We report the case of a 69-year-old man with endotracheal ETT presenting with severe dyspnea, and the lesion was initially suspected to be malignant.

Chest imaging in children presents unique challenges due to varying requirements across age groups. For chest radiographs, achieving optimal images often involves careful positioning and immobilisation techniques. Antero-posterior projections are easier to obtain in younger children, while lateral decubitus radiographs are sometimes used when expiratory images are difficult to obtain and for free air exclusion.

Introduction: A significant portion of posterior urethral valve patients continue to progress to end stage renal disease despite improvements in medical care. Socioeconomic status has been connected to various healthcare outcomes but has not been evaluated in relation to longitudinal outcomes of posterior urethral valves.
Objective: To evaluate the effect of socioeconomic status on the progression to renal failure among patients with posterior urethral valves.

Dysregulation of genes encoding the homologous to E6AP C-terminus (HECT) E3 ubiquitin ligases has been linked to cancer and structural birth defects. One member of this family, the HECT-domain-containing protein 1 (HECTD1), mediates developmental pathways, including cell signaling, gene expression, and embryogenesis. Through GeneMatcher, we identified 14 unrelated individuals with 15 different variants in HECTD1 (10 missense, 3 frameshift, 1 nonsense, and 1 splicing variant) with neurodevelopmental disorders (NDDs), including autism, attention-deficit/hyperactivity disorder, and epilepsy.
