In this article, a 9-year-old male patient with a compound depressed skull fracture overlying the superior sagittal sinus and an intracranial stone foreign body is presented. A cerebral penetrating injury caused by a stone is rare. The computed tomography images obtained at standard window widths and window density levels may not reveal a retained stone, which has a chemical structure similar to bone and may not show any artifacts in the computed tomography scans.

Cornelia de Lange syndrome (CdLS) is a rare genetic disorder characterized by a distinctive facial appearance, growth/cognitive retardation, developmental delay, skeletal malformation, hypertrichosis, and other abnormalities. Patients with mild CdLS have less severe phenotypes, while retaining representative facial features. Mutations in the genes , , , , and have been associated with CdLS, with mutations in accounting for approximately 60% of cases.

The traditional method of performing open common bile duct exploration (OCBDE) was replaced by a less invasive procedure known as laparoscopic common bile duct exploration (LCBDE) in elective surgery. But at present, the application of this technique is considered novel and controversial to treat acute cholangitis (AC). The aim of our systematic review was to investigate the safety and efficacy of laparoscopic surgery in patients with AC.

Background: Prune belly syndrome (PBS) is a rare condition characterized by absence of abdominal musculature, cryptorchidism, and obstructive uropathy. The most common orthopaedic problem is scoliosis, yet no reports on growth-friendly surgical treatment of early-onset scoliosis (EOS) exist. Our purpose was to evaluate outcomes of distraction-based implants in children with PBS.

Using an interatomic potential that can capture the tetrahedral configuration of water molecules (HO) in ice without the need to explicitly track the motion of the O and H atoms, coarse-grained (CG) atomistic simulations are performed here to characterize the structures, energy, cohesive strengths, and fracture resistance of the grain boundaries (GBs) in polycrystalline ice resulting from water freezing. Taking the symmetric tilt grain boundaries (STGBs) with a tilting axis of ⟨0001⟩ as an example, several main findings from our simulations are (i) the GB energy, , exhibits a strong dependence on the GB misorientation angle, θ. The classical Read-Shockley model only predicts the - θ relation reasonably well when θ < 20° or θ > 45° but fails when 20° < θ < 45°; (ii) two "valleys" appear in the -θ landscape.
