Comparison of the Clinical Efficacy and Bone Cement Distribution Difference Between Kummell's Disease and Osteoporotic Vertebral Compression Fracture After Percutaneous Kyphoplasty.

Background: Kummell's disease (KD) and osteoporotic vertebral compression fracture (OVCF) are commonly found in patients with osteoporosis. Several studies have been conducted on bone cement distribution in OVCF or KD; a comparison between the 2 diseases is rarely reported.

Objectives: To compare the clinical efficacy and bone cement distribution difference between KD and OVCFs after percutaneous kyphoplasty (PKP).

The development and application of pediatric complicated appendicitis prediction model.

Background: Acute appendicitis in children refers to the acute inflammation of the appendix, which accounts for 20% ∼ 30% of cases of acute abdomen in pediatric surgery.

Objective: This study aimed to establish a decision tree model of complicated appendicitis in children using appendiceal ultrasound combined with an inflammatory index and evaluated its clinical efficacy in pediatric patients.

Methods: A total of 395 children admitted to the Emergency Department of the Shanghai Children's Hospital from January 2018 to December 2021 and diagnosed with appendicitis by postoperative pathology were retrospectively analyzed.

A novel puncture approach via point "O" for percutaneous kyphoplasty in patients with L4 or L5 osteoporotic vertebral compression fracture.

This study introduced a novel point "O" puncture approach for percutaneous kyphoplasty (PKP) in patients with L4 or L5 osteoporotic vertebral compression fracture (OVCF) and evaluated its clinical and radiographic outcomes. Between September 2019 and December 2020, we compared the clinical and radiographic outcomes in 31 cases (36 vertebrae) using the "O" entry point PKP intervention (O-PKP) and 31 cases (37 vertebrae) using transverse the process-pedicle approach PKP intervention (T-PKP). No serious postoperative complications were observed in any of the participants.

Exposure to air pollutants during pregnancy and after birth increases the risk of neonatal hyperbilirubinemia.

Objectives: Exposure to air pollution is associated with increased risks of several adverse conditions in newborns, such as preterm birth. Whether air pollution is associated with neonatal hyperbilirubinemia remains unclear. We aimed to develop and validate an air-quality-based model to better predict neonatal hyperbilirubinemia.
