Objective: This clinical report describes an alternative treatment modality for the replacement of congenitally missing maxillary lateral incisors in a 17-year-old patient.
Clinical Considerations: Zirconia-based resin-bonded fixed partial dentures (RBFPDs) were selected as a viable and conservative treatment option in a young individual with highly aesthetic expectations. Fabrication of all-ceramic RBFPDs followed specific preparation design and features to accommodate two retainers. The zirconia frameworks with bilateral wings were digitally designed and then milled by a computer-aided design and computer-aided manufacturing (CAD/CAM)-controlled milling machine. Zirconia surface was treated with a two-step chairside tribochemical silica-coating/silane coupling surface treatment protocol, and adhesive resin luting cement was used to achieve micromechanical and chemical bonding. Completion of the treatment resulted in a functional and aesthetic successful outcome and a 17-month follow-up presented uneventful.
Conclusion: Contemporary adhesive techniques involving resin-bonded zirconia-based prostheses can be utilized successfully and predictably in young patients with single missing teeth when implant therapy is currently not a treatment of choice and a less invasive approach is desired.
Clinical Significance: The zirconia-based resin-bonded prosthesis constitutes a viable and conservative treatment modality for the replacement of missing teeth either congenitally or from another etiology in young patients in which implant therapy and a fixed partial denture are currently contraindicated.

Unlabelled: The Bland-White-Garland syndrome, or Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery (ALCAPA) syndrome, is a rare congenital cardiac anomaly often associated with high mortality, if left untreated. We present a case of a 43-year-old female with undiagnosed ALCAPA who initially underwent mitral valve surgery for severe mitral regurgitation, only to require reoperation due to adult-type ALCAPA. Intraoperatively, the discovery of dilated right coronary artery and its branches and absence of the left coronary ostium prompted further investigation, leading to the diagnosis of adult-type ALCAPA.

Introduction: Duplication of the gallbladder is a rare congenital malformation associated with the development of cholelithiasis. It increases the risk of iatrogenic bile duct injury during cholecystectomy and can lead to symptom recurrence if missed. Although preoperative imaging is helpful, detection rates are around 50 %.

Pituitary stalk interruption syndrome (PSIS) is a congenital anatomical defect that leads to pituitary insufficiency, The symptoms are diverse, often leading to diagnostic delays or even misdiagnosis. MRI plays a crucial role in establishing an accurate diagnosis by revealing a characteristic radiological triad: a thin or absent pituitary stalk, an ectopic or missing posterior pituitary gland, and anterior pituitary hypoplasia. We herein describe 2 cases: 1 involving a 9-year-old boy and the other an 11-year-old girl, both diagnosed with PSIS.

Prcis: Guardian education level and frequency of surgical interventions are key determinants of knowledge in primary congenital glaucoma, highlighting the need for targeted educational strategies.
Background: Management of congenital glaucoma poses unique challenges, particularly concerning the patient guardians' understanding of the condition, which is crucial for treatment adherence and follow-up compliance. This study aimed to assess guardians' knowledge levels and identify the influencing factors.
Sox10 is required for systemic initiation of bone mineralization.

Heterozygous variants in SOX10 cause congenital syndromes affecting pigmentation, digestion, hearing, and neural development, primarily attributable to failed differentiation or loss of non-skeletal neural crest derivatives. We report here an additional novel requirement for Sox10 in bone mineralization. Neither crest- nor mesoderm-derived bones initiate mineralization on time in zebrafish sox10 mutants, despite normal osteoblast differentiation and matrix production.
