Palmar approach with Kirschner-wire fixation in the treatment of children's distal radius extension type fracture.

Purpose: To explore the advantages of palmar approach with Kirschner-wire (K-wire) fixation in the treatment of children's distal radius extension type fracture.

Methods: Thirty patients, average age of 8.5 years ranging from 5 to 13 years, with distal radius extension type fracture and undergoing a failed manual reposition in our hospital were included, and treated by palmar approach with K-wire fixation between May 2014 and December 2017.

Clinical significance of imaging findings for atlantoaxial rotatory subluxation in children.

Background/aim: This study evaluated the usefulness of measuring the atlantodental interval (ADI) and lateral atlantodental spaces (LADSs) by retrospectively analyzing the imaging data of children of various ages with and without atlantoaxial rotatory subluxation (AARS). Materials and methods: The data of 495 children who underwent cranial computed tomography were collected. Among these children, 255 children were clinically diagnosed with AARS while 240 children were not.

[Expression of neuron-specific enolase and synaptophysin in esophageal development of human embryos].

Objective: To investigate the expression of neuron-specific enolase (NSE) and synaptophysin(SYN) proteins in different developmental stages of human embryonic esophagus.

Methods: Immunohistochemistry was used to detect the expressions of NSE and SYN proteins in embryonic esophagus tissues of fetuses of 2, 3 and 4 month gestational age (n=16). One-way ANOVA and LSD-t test were employed to compare the staining intensity and number of positive expression cells in embryonic esophageal tissues of different gestational age.
