Double vascularized fibula growth plate transfer for the reconstruction of long segmental tibia in pediatric patients: Report of three cases.

Osteosarcoma is a common bone tumor for pediatric patients that has a complex treatment including chemotherapy and radical surgical resection. There are few functional leg reconstruction possibilities described in the literature for pediatric patients due to limited growth potential. The aim of this report is to show long-term results using double vascularized growth plate flaps for the long segmental tibial reconstruction in growing children with satisfactory functionality and preserved limb growth without the use of permanent foreign materials.

Serum and Urine Biomarker Leucine-Rich Alpha-2 Glycoprotein 1 Differentiates Pediatric Acute Complicated and Uncomplicated Appendicitis.

Purpose: This prospective, single-center cohort study analyzes the potential of inflammatory protein mediator leucine-rich alpha-2 glycoprotein 1 (LRG1) for the early and accurate diagnosis of acute appendicitis (AA), and differentiation of acute complicated (AcA) from uncomplicated appendicitis (AuA).

Methods: Participants were divided into the AcA, AuA, and control groups, and their serum (s-LRG1) and urine LRG1 (u-LRG1) levels were assayed preoperatively on the second and fifth postoperative days.

Results: 153 patients participated, 97 had AA.
