ABSTRACT

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. METHODS: We retrospectively reviewed the medical records of children aged <16 years with trampoline-related injuries who visited our Emergency Department between 2008 and 2017. RESULTS: Over the 10-year period, 178 trampoline-related injuries were reported, which represented a significant increase (P=0.016). Most (87.6%) of the injuries occurred during the last 5 study years, and a rapid increase in injuries was observed in children aged <6 years. Lower extremity injuries (62.4%) were the most common, followed by injuries of the upper extremities, head and face, and trunk, including injuries to the neck and spine. Sixty-seven children (37.6%) had fractures, and proximal tibia fractures were the most common. Fractures were significantly more common in younger children (<6 years old) than in older children (P=0.026). CONCLUSION: In Korea, the mechanism of trampoline injury is similar to that of injuries incurred in indoor trampoline parks but is characterized by smaller spaces and multiple users. Trampoline use and the incidence of trampoline-related injuries in children aged <6 years are increasing rapidly. Prohibiting the use of trampolines for children aged <6 years, restricting simultaneous use by multiple children, and ensuring adult supervision should be strictly emphasized. Public awareness and policy guidelines are needed to reduce the incidence of trampoline-related injuries.

ABSTRACT

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. The uncomplicated group included patients with simple, focal, or suppurative appendicitis, and the complicated group included patients with gangrenous, perforated appendicitis or periappendiceal abscess formation. The 2 groups were analyzed by age, sex, and time. RESULTS: A total of 192 patients were analyzed. The mean time from symptom onset to start of operation showed a significant difference between both groups (1,652.9 minutes vs. 3,383.8 minutes, P < 0.001). The mean time from hospital visit to start of operation showed no difference between both groups (398.7 minutes vs. 402.0 minutes, P = 0.895). Operating within 24 hours of symptom onset had a relative risk of 1.738 (95% confidence interval, 1.319-2.425) for complications. Operating more than 36 hours after symptom onset was associated with an increased risk of postoperative ileus and a longer hospital stay. CONCLUSION: Complicated appendicitis is associated with a delay in surgery from symptom onset rather than a delay at hospital arrival. Surgeons should take into account the time from symptom onset when deciding on the timing of appendectomy. We recommend that appendectomy be performed within 36 hours from symptom onset.

ABSTRACT

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. They were divided into complicated appendicitis and non-complicated appendicitis groups and their preoperative laboratory results were reviewed. RESULTS: A total of 234 patients were included. Elevated international normalized ratio (INR) and serum C-reactive protein (CRP) were associated with complicated appendicitis (p = 0.001). On ROC curve analysis, area under the curve (AUC) of CRP and INR were 0.796 and 0.723, respectively. CONCLUSIONS: INR and CRP increased significantly in patients with complicated appendicitis. Further studies evaluating INR and CRP in patients undergoing conservative management for appendicitis are required.

ABSTRACT

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. CD133 and ALDH1 expression were determined by immunohistochemistry. RESULTS: CD133 and ALDH1 expression were positive in 24.7% and 22.0% of the patients, respectively, and were associated with tumor size, cancer stage, estrogen receptor negativity, nonluminal subtype, triple-negative breast cancer, and recurrence. CD133 expression was significantly associated with lymph node metastasis, progesterone receptor negativity, human epidermal growth factor receptor 2 positivity, chemotherapy, and poor disease-free (p=0.002) and overall survival (p=0.014), but ALDH1 expression was not. Cancer stage (p<0.001) was an independent prognostic factor for disease-free survival in multivariate analysis. Cancer stage (p<0.001) and receipt of radiotherapy (p=0.045) were independent prognostic factors for overall survival in multivariate analysis. CONCLUSION: CD133 or the combination of CD133 and ALDH1 expression were more widely associated with the presence of adverse biomarkers and subtypes of breast cancer, compared to ALDH1 expression alone, and these markers may have a potential predictive role and be a helpful tool in the management for patients with invasive breast cancer.
