Cecal volvulus is a rare condition, particularly in the pediatric population, and is associated with serious complications such as ischemia, gangrene, or perforation. Its clinical presentation is often vague and variable, which may delay diagnosis. We present a case of a 10-year-old female who presented to the emergency department with an acute abdomen. Imaging findings showed bowel obstruction, and she subsequently underwent an emergency laparotomy, which confirmed the presence of cecal volvulus. She recovered well and was discharged in stable condition. This case highlights the importance of early recognition and timely management of cecal volvulus to achieve successful outcomes and is supported by a review of the relevant literature.

Purpose: We aimed to analyze pediatric drowning cases to study age group-related clinical characteristics, such as causes, location, and outcomes, in an under-researched area in South Korea. Methods: From January 1, 2020 through July 20, 2025, we retrospectively analyzed medical records of patients aged 19 years or younger who had experienced drowning and visited Kangwon National University Hospital located in the northern Yeongseo region of Gangwon Province. Their clinical characteristics were compared between those with worse outcomes, defined as hospitalization to the intensive care unit or in-hospital mortality, and those with better outcomes. Results: During the period, 27 patients having undergone drowning accidents visited the hospital. The most frequent location was the bathtub at home in the patients younger than 1 year (all 4 patients), commercial swimming pools in those aged 1-14 years (12 of the 16 patients), and rivers in those aged 15-19 years (all 7 patients). Of the 27 cases, 11 had worse outcomes including 4 mortalities. Patients with worse outcomes had higher percentages of guardian’s negligence, altered mental status, pool or river as the location, implementation of oxygen therapy or positive pressure ventilation, and lower mean initial Korean Triage and Acuity Scale (i.e., higher acuity), as well as higher mean concentrations of glucose, urea nitrogen, aspartate aminotransferase, and base deficit. Conclusion This study on pediatric drowning patients in the under-researched area showed age-related differences in the primary causes of drowning and clinical features related to the worse outcomes. These findings need to be considered for prompting increased parental vigilance and more comprehensive societal preventive measures.

Purpose: The clinical utility of routine repeat computed tomography (CT) in pediatric patients with mild traumatic brain injury (TBI) remains controversial. We aimed to identify factors associated with worsening intracranial injury (ICI) on repeat CT in pediatric patients with mild TBI. Methods: This retrospective study included patients aged 0–18 years with mild TBI (Glasgow Coma Scale score 13–15) who presented to an emergency department in South Korea from January 2017 through December 2023. Patients were included if they underwent an initial CT within 24 hours of injury and a repeat CT within 72 hours. Worsening ICI was defined as an increase in hemorrhage size or the development of new lesions on repeat CT. Clinical characteristics, injury mechanisms, and CT findings were compared between patients with and without the worsening ICI. Multivariable logistic regression was performed to identify independent predictors of worsening ICI on repeat CT. Results: A total of 212 patients were included, of whom 48 (22.6%) showed worsening ICIs on repeat CT (i.e., worsening group). The worsening group showed higher median values of age and length of hospital stay, as well as higher percentages of initial Glasgow Coma Scale of 14, motorcycle/bicycle injury, intensive care unit hospitalization, and abnormalities on initial CT (including skull fracture, epidural hemorrhage, subdural hemorrhage, and pneumocephalus), compared with their counterparts. The regression model showed subdural hemorrhage (odds ratio, 4.99 [95% confidence interval, 2.08–11.96]), epidural hemorrhage (4.04 [1.73–9.44]), and motorcycle/bicycle as the injury mechanism (2.94 [1.14–7.59]) as the predictors. Conclusion In pediatric mild TBI, motorcycle/bicycle accidents and the presence of hemorrhages on initial CT may be associated with worsening ICI on repeat CT. These findings support a risk-stratified approach, in which repeat imaging is selectively considered for high-risk patients to reduce unnecessary radiation exposure.

Dilated cardiomyopathy is the most common form of cardiomyopathy in children and often leads to irreversible myocardial dysfunction. To improve the prognosis, it is critical to identify rare but reversible causes. We report a 12-year-old girl referred to the emergency department for dyspnea on exertion and generalized edema that lasted for 1 month. She gained 20 kg over the past 3 years, which had gone uninvestigated. Transthoracic echocardiography demonstrated left ventricular dysfunction with pericardial effusion. Thyroid function tests revealed concentrations of free T4 and thyroid-stimulating hormone of 0.12 ng/dL (reference value, 0.93-1.7) and 86.9 µIU/mL (0.3-4.2), respectively, with anti-thyroid peroxidase and anti-thyroglobulin antibodies elevated, confirming the presence of autoimmune hypothyroidism. We initiated heart failure management alongside levothyroxine replacement therapy. After 5 months of treatment, a follow-up echocardiography showed improved left ventricular and thyroid function.

Superior mesenteric artery syndrome (SMAS) is a rare but important cause of acute upper gastrointestinal obstruction resulting from compression of the duodenal third portion between the superior mesenteric artery and aorta. While SMAS has been described after corrective spinal surgery, it is rarely reported following pediatric trauma. We describe an 8-year-old boy involved in a high-speed motor vehicle collision who sustained multiple severe injuries, such as traumatic diaphragmatic hernia, mesenteric vascular injury, hepatosplenic laceration, and L1–L2 seatbelt-related Chance fracture-dislocation. After surgical stabilization of the spine on day 6, he presented on day 12 with bilious vomiting and abdominal distension, indicating the presence of intestinal obstruction. Contrast-enhanced computed tomography and an upper gastrointestinal series demonstrated narrowing of aorto-mesenteric angle with compression of the duodenal third portion, confirming the diagnosis of SMAS. Through nasojejunal tubal feeding, he was able to meet nutritional requirements without parenteral nutrition. This case underscores the need for heightened awareness of SMAS in pediatric trauma patients who develop postoperative duodenal obstruction symptoms, as prompt recognition and conservative management in the postoperative setting can lead to excellent outcomes.

We evaluated the content fidelity of written discharge instructions (WDIs) for pediatric patients with mild traumatic brain injury (mTBI). In May 2023, copies of WDIs were collected from 55 academic hospitals across South Korea. Each document was scored for the fidelity of medical advice based on the “Counsel” section of the Pediatric mTBI Guideline Checklist of the Centers for Disease Control and Prevention (maximum 10 points). Among respondent 46 emergency departments, 21 (45.7%) provided WDIs to patients with mTBI. The median score was 6.0 (interquartile range, 4.0-7.0), indicating that the fidelity of the WDIs needs improving.

Purpose: This study analyzed the characteristics of pediatric patients’ (≤ 18 years) intentional injury-related visits to the emergency department (ED) using National Emergency Department Information System data from January 1 through December 31, 2023, providing foundational evidence for prevention strategies and policy development. Methods: The injuries were categorized into unintentional and intentional, and relevant characteristics were compared between the 2 categories. The intentional injuries were further divided into self-harm and violence. Percentages were calculated for each variable and compared using the chi-square or Fisher exact tests. Results: Among 301,852 pediatric patients, those with intentional injuries showed higher proportions of girls, adolescents, visits in the wee hours, visits via firehouse ambulances, injuries by collision, by penetration, or by poisoning, hospitalization, Korean Triage and Acuity Scale levels 1-3, an ED length of stay of 2 hours or longer, and primary care by psychiatrists, than those with unintentional injuries. The pediatric patients with self-harm injuries showed higher proportions of girls, adolescents, visits in the wee or morning hours, visits via firehouse ambulances, injuries by collision, by penetration, or by poisoning, hospitalization or inter-facility transfer, Korean Triage and Acuity Scale levels 1-3, an ED length of stay of 2 hours or longer, and primary care by psychiatrists as well as by orthopedic surgeons or pediatricians, than those with violence injuries. Conclusion This study highlights the need to develop strategies per age and sex for preventing self-harm among pediatric patients, and to ensure safe and effective psychiatric care in EDs. In addition, the prevention of child abuse requires a multidisciplinary approach that includes preventive education programs, mandatory reporting in EDs, and the adoption of screening tools such as the Finding Instrument for Non-accidental Deeds.

Purpose: Toy guns are popular among children but can pose serious risks of eye injury. This study analyzed toy gun-related ocular injuries (TGOIs) in pediatric patients over 20 years using the United States national data. Methods: A retrospective cross-sectional analysis was performed using the U.S. National Electronic Injury Surveillance System data from 2005 through 2024. We studied cases of pediatric patients presenting to emergency departments with TGOIs. Descriptive and comparative analyses were performed, and trends were analyzed across the study period, using chi-square test and analysis of variance. Results: A total of 695 pediatric cases of TGOI were identified, corresponding to an estimated 16,325 national cases in the U.S. Most injuries occurred in males (77.4%) and age of 7-12 years (54.0%). Common diagnoses included corneal abrasion (33.5%) and hyphema (22.2%), with severe cases also reported such as ruptured globe (1.0%) and corneal laceration (0.3%). Injuries were most frequent during winter (32.1%). Over the study period, there were increases in mean age (from 8.9 years [2005-2009] to 9.6 years [2020-2024]), overall reported number of cases (from 47 to 341), and diagnosis of hyphema (from 8.5% to 25.2%). Conclusions Pediatric TGOI is increasing in frequency, with shifting demographic and clinical patterns. These findings highlight the urgent need for enhanced safety regulations and public health interventions to prevent vision-threatening trauma in children.

We report a case of a previously healthy 9-year-old boy who presented to the emergency department following accidental ingestion of 35% hydrogen peroxide. He developed emesis and mild abdominal pain and was found to have extensive portal venous gas, severe gastric pneumatosis, and free intraperitoneal air on a computed tomography scan. He was transferred to an outside hospital for hyperbaric oxygen therapy, with no emergency surgical intervention indicated. This case highlights the dangers of ingesting even a small amount of concentrated hydrogen peroxide in children and underscores the safe storage practices at home.
