The purpose of this study was to investigate changes in cranial shape among preterm neonates aged 1-6 months and the relationship between developmental quotient (DQ) and cranial shape at 6 months of age. Preterm infants who were hospitalized in our hospital were prospectively followed for 6 months. The cephalic index (CI) and cranial vault asymmetry index (CVAI) were evaluated at 1 (T1), 3 (T2), and 6 months (T3) of age and compared with those of the full-term infants. The relationship between CI or CVAI and DQ at T3 was analyzed using the Enjoji Scale of Infant Analytical Development. A total of 26 participants born at 34.7 ± 1.9 weeks of gestation were included. The CI increased with age (T1: 77.2%, T2: 82.9%, T3: 85.4%, < 0.01). The prevalence of dolichocephaly at T3 did not significantly differ from that in full-term infants (15.4% vs. 4.5%, = 0.08). CVAI did not significantly differ between preterm and full-term infants. The DQ showed no significant correlation with either the CI or CVAI (correlation coefficients: 0.23 for CI, -0.01; CVAI). Dolichocephaly improved over time in preterm infants and no relationship between cranial shape and development was observed in preterm infants at 6 months of age.

Objective: To apply a network medicine-based approach to analyze the phenome of the prenatal fetal MRI and biometric findings in the Chiari II malformation (CM II) to detect specific patterns and co-occurrences.
Method: A single-center retrospective review of fetal MRI scans obtained in fetuses with CM II was performed. Co-occurrence analysis was utilized to generate a phenotypic comorbidity matrix and visualized by Gephi software.

Background: Molariform second premolar is a rare dental anomaly where the second premolar resembles a molar in size and shape. This condition is often linked to macrodontia, a rare enlargement of teeth that disrupts dental proportions and can manifest in isolated, relative, or generalized forms. Although mandibular second premolars are more prone to morphological variability, the occurrence of bilateral molariform premolars, induced by a unique form of gemination, is exceptionally uncommon and infrequently documented, thus making this case clinically significant.

Article Synopsis
- This study examines how the growth and calcification of the appendicular skeleton in the Raja asterias affects its movement in water, highlighting the link between bone structure and fin mechanics.
- It identifies two growth patterns—crustal in larger skeletal parts and catenated in fin radials—showing how differences in development can influence fin flexibility and locomotion.
- The results suggest that unique calcification patterns, especially in the pelvic fins, evolve to meet the mechanical needs of swimming, emphasizing the adaptability of Batoidea fins through their joint structures and specialized designs.

Article Synopsis
- The study investigates the effectiveness of a surgical procedure (extended strip craniectomy with bilateral barrel staving) for treating isolated craniosynostosis of the sagittal suture in infants, specifically focusing on its impact on cranial shape without directly addressing forehead issues.
- Results showed significant improvements in aspects like bossing angle and cephalic index over a year, although the cranial shape did not entirely match that of healthy peers, indicating partial normalization but not complete correction.
- The research validates 3D photogrammetry as a useful noninvasive tool for assessing cranial changes post-surgery, suggesting potential for wider clinical applications in monitoring cranial morphology.

Objective: Sagittal synostosis is the most common type of craniosynostosis, resulting in deformity with distinctive morphological characteristics. These include occipital narrowing, parietal narrowing, anteriorly shifted vertex with parietal depression, and exaggerated frontal bossing. The traditional cephalic index affords limited reliability in quantifying initial severity and correction.
