Characterization of Injury Induced by Routine Surgical Manipulations of Nasal Septal Cartilage.

Importance: This study characterizes and compares common surgical manipulations' effects on septal cartilage to understand their implications for rhinoplasty outcomes based on cell viability and cartilage health.

Objective: To illustrate distinct differences in the impact of various surgical manipulations on septal cartilage in an in vitro septal cartilage model. A secondary objective is to better understand the chondrocyte's response to injury as well as how alterations in the extracellular matrix correspond to chondrocyte viability.

The utility of home problem pervasiveness and severity in classifying children identified with attention-deficit/hyperactivity disorder.

Given the propensity for clinical assessment of Attention-Deficit/Hyperactivity Disorder (ADHD) to focus on core behavioral symptoms, the current study examined how well other predictors classified children who were diagnosed with ADHD by licensed practitioners. Participants were 91 children (39 ADHD-identified, 52 without ADHD), aged 8 to 13 years. In addition to significantly more ADHD symptoms, the ADHD-identified group exhibited significantly more externalizing problems and internalizing symptoms, less adaptive functioning, and greater problem pervasiveness and severity.
