The Sanders Classification and Obesity: Do Obese Kids With AIS Present With More Advanced Skeletal Maturity?

Introduction: Obese and overweight (OOW) patients with adolescent idiopathic scoliosis (AIS) have been shown to initially present with a more advanced Risser score compared to normal weight (NW) patients. The Sanders Maturity Scale (SMS) is now more commonly used by surgeons to assist with treatment decisions because it more reliably predicts skeletal maturity. However, the relationship between SMS and obesity has not been described.

Does Obesity Affect Preoperative Shoulder Balance in Adolescent Idiopathic Scoliosis?

Background: Obese patients with adolescent idiopathic scoliosis (AIS) have been shown to present with larger curve magnitudes preoperatively. However, the effect of obesity on shoulder balance in AIS remains unknown. The purpose of our study was to determine if overweight and obese patients with AIS have worse radiographic shoulder balance on initial presentation when compared with normal weight patients.

The value-added benefit of utilizing two attending surgeons for patients with scoliosis secondary to cerebral palsy.

Purpose: The use of two attending surgeons during posterior spinal fusion (PSF) for cerebral palsy (CP) patients has been shown to improve perioperative outcomes. This study aims to determine if the use of two surgeons is associated with an increase in the number of subsequent surgeries that can be performed in the same operating room (OR) during business hours.

Methods: Patients with scoliosis and CP treated with PSF with minimum 90-day follow-up were included.

Natural killer cells mediate pathophysiology in response to reduced uterine perfusion pressure.

Preeclampsia is associated with hypertension, small-for-gestational-age babies, and increased cytolytic natural killer (NK) cells. The specific role of cytolytic NK cells in the pathophysiology of preeclampsia has not been clearly defined. We hypothesized that educed terine erfusion ressure (RUPP) stimulates proliferation and cytolytic activation of NK cells, and that reducing NK cells in RUPP would prevent hypertension, intrauterine growth restriction, and inflammation in response to placental ischemia.
