Rapidly growing pediatric trampoline-related injuries in Korea: a 10-year single center retrospective study.

Purpose: Several published policy statements have warned against the risks associated with trampoline use and recommended safety guidelines. However, few studies have focused on trampoline-related injuries in Korea. This study aimed to assess the incidence and characteristics of pediatric trampoline-related injuries presented to Ulsan University Hospital.

Effect of surgical timing and outcomes for appendicitis severity.

Purpose: This study was aimed to evaluate the effect of time of surgery for acute appendicitis on surgical outcomes to optimize the timing of appendectomies.

Methods: Medical records of patients who underwent an appendectomy were reviewed to obtain data on time of symptom onset, time of hospital presentation, and start times of surgery. Surgical findings were used to define appendicitis as either uncomplicated or complicated.

International normalized ratio and serum C-reactive protein are feasible markers to predict complicated appendicitis.

Background: Diagnostic approach for complicated appendicitis is still controversial. We planned this study to analyze preoperative laboratory markers that may predict complications of appendicitis.

Methods: Patients who underwent appendectomy were retrospectively recruited.

Prognostic Impact and Clinicopathological Correlation of CD133 and ALDH1 Expression in Invasive Breast Cancer.

Purpose: CD133 and aldehyde dehydrogenase 1 (ALDH1) expression are reliable poor-prognosis markers associated with the presence of adverse biomarkers and subtypes of breast cancer. The aim of our study was to investigate and compare the clinical impact of CD133 and ALDH1 expression in invasive breast cancer.

Methods: A total of 291 consecutive patients with invasive breast cancer who underwent breast cancer operations from 2005 to 2010 at a single institution were included in this retrospective review.
