BACKGROUND AND OBJECTIVES: Temporal bone fracture (TBF) is a common occurrence in cases of head trauma. Although the incidence of temporal bone concussion (TBC) has increased in cases of head trauma, it has not been extensively studied. We assessed the characteristics of TBF and TBC in patients with head trauma. SUBJECTS AND METHODS: We conducted a retrospective review of 432 patients with head injury who visited our hospital between January 2011 and April 2016. Of these patients, 211 who met the inclusion criteria were included in the study. Their clinical characteristics, causes of injury, and hearing function were analyzed. RESULTS: Among the 211 patients, 157 had TBFs and 54 had TBCs. Ear symptoms were more common among patients with TBF than among those with TBC. Car accidents were the most common cause of both TBF and TBC, but assault and sports injuries were more common among patients with TBC than among those with TBF. The occurrence of facial palsy in both cases of TBF and TBC. Hearing loss was observed among 35 patients with TBF and 11 patients with TBC. However, patients with TBF showed conductive hearing loss with an air-bone gap. Hearing function of these patients with TBF recovered with a reduced air-bone gap, but the patients with TBC showed little recovery. CONCLUSIONS: Emergency physicians should focus more on temporal bone injury in patients with head trauma. Therefore, an early complete diagnostic battery, which includes high-resolution computed tomography, audiometric tests, neurologic examination, and vestibular tests, be performed in patients with head trauma.

Intraorbital infection shows a low incidence, but it might cause blindness or even death. This case is unusual in that its origin from a craniofacial bone fracture prior to infection of the maxillary sinus. A 33-year-old female patient was referred for right cheek swelling. When she visited the emergency room, we removed right cheek hematoma and bacterial examination was done. In the past, she had craniofacial bone surgical history due to a traffic accident 6 years ago. Next day, the swelling had remained with proptosis and pus was recognized in the conjunctiva. We planned an emergency operation and removed the pus which was already spread inside the orbit. And the evaluation for sinusitis was consulted to the otorhinolaryngology department simultaneously. There were Prevotella oralis and methicillin-resistant Staphylococcus epidermidis bacterial infection in the intraorbital and sinus respectively. Afterwards, the vigorous dressing was done for over a month with intravenous antibiotics. Though the intraorbital infection was resolved, blindness and extraocular movement limitation were inevitable. In conclusion, close follow up of the maxillary sinus in facial bone fracture patients is important and aggressive treatment is needed when an infection is diagnosed.

PURPOSE: To evaluate interpretation errors involving spine MRIs by residents in their second to fourth year of training, classified as minor, intermediate and major discrepancies, as well as the types of commonly discordant lesions with or without clinical significance. MATERIALS AND METHODS: A staff radiologist evaluated both preliminary and final reports of 582 spine MRIs performed in the emergency room from March 2011 to February 2013, involving (1) the incidence of report discrepancy, classified as minor if there was sufficient description of the main MR findings without ancillary or incidental lesions not influencing the main diagnosis, treatment, or patients' clinical course; intermediate if the correct diagnosis was made with insufficient or inadequate explanation, potentially influencing treatment or clinical course; and major if the discrepancy affected the main diagnosis; and (2) the common causes of discrepancy. We analyzed the differences in the incidence of discrepancy with respect to the training years of residents, age and sex of patients. RESULTS: Interpretation discrepancy occurred in 229 of the 582 cases (229/582, 39.3%), including 146 minor (146/582, 25.1%), 40 intermediate (40/582, 6.9%), and 43 major cases (43/582, 7.4%). The common causes of major discrepancy were: over-diagnosis of fracture (n = 10), missed cord lesion (n = 9), missed signal abnormalities associated with diffuse marrow (n = 5), and failure to provide differential diagnosis of focal abnormal marrow signal intensity (n = 5). No significant difference was found in the incidence of minor, intermediate, and major discrepancies according to the levels of residency, patients' age or sex. CONCLUSION: A 7.4% rate of major discrepancies was found in preliminary reporting of emergency MRIs of spine interpreted by radiology residents, probably related to a relative lack of clinical experience, indicating the need for additional training, especially involving spine trauma, spinal cord and bone marrow lesions.

In this study, we investigated playground equipment related injuries in preschool-aged children. This was a retrospective observational study using Emergency Department based Injury In-depth Surveillance, (2011–2014). We included the preschool-aged children with playground equipment related injuries. We surveyed the mechanism and incidence of injuries, and estimated the odds ratio (OR) of traumatic brain injury (TBI) and upper/lower extremities fracture. There were 6,110 patients, mean age was 4.14 ± 1.95 years old. Slide and swing related injuries were 2,475 (40.5%) and 1,102 (18.0%). Fall down (48.5%) was the most common mechanism. The OR of TBI in children 0–2 years old was 1.88 times higher than children 3–7 years old, and in swing was 4.72 (OR, 4.72; 95% confidence interval [CI], 2.37–9.40) times higher than seesaw. The OR of upper extremity fracture in children 3–7 years old was 3.07 times higher than children 0–2 years old, and in climbing was 2.03 (OR, 2.03; 95% CI, 1.63–2.52) times higher than swing. The OR of lower extremity fractures in horizontal bars, tightropes, and trampolines was 2.95 (OR, 2.95; 95% CI, 1.55–5.61) times higher than swing. The most common mechanism and playground equipment were fall down and slide. TBI was associated to younger children (0–2 years old) and swing. Fracture of upper extremities was associated to older children (3–7 years old) and climbing. Fracture of lower extremities was associated to others such as horizontal bars, tightropes, and trampolines.

PURPOSE: Analgesia is essential for the treatment of children's fracture. We aimed to investigate the factors associated with administration of analgesics in children with forearm fracture. METHODS: We retrospectively reviewed medical records of children (< 20 years) with forearm fracture who visited 2 tertiary hospital emergency departments from 2014 to 2015. We analyzed factors, such as gender, age, whether the mother accompanied the visit, visiting time and route, mechanism of injury, duration of symptoms, complicated fracture, manual reduction, surgery, and type and route of analgesics. We also performed logistic regression analysis to identify the factors associated with administration of analgesics. RESULTS: Of 179 children with forearm fracture, 48 (26.8%) were administered analgesics. These children showed older age, shorter duration of symptoms, and more frequent visit with their mothers, visit during the day, use of emergency medical services, and surgery. After logistic regression analysis, we found use of emergency medical service (adjusted odds ratio [OR], 8.73; 95% confidence interval [CI], 3.16–24.08; P < 0.001), visit with the mother (OR, 6.23; 95% CI, 1.68–23.09; P = 0.006), age (OR, 1.18; 95% CI, 1.05–1.32; P = 0.004), and duration of symptoms (OR, 0.99; 95% CI, 0.986–0.999; P = 0.035) as the factors associated with administration of analgesics. CONCLUSION: The factors associated with administration of analgesics might be communicating skill-related factors, such as older age and shorter duration of symptoms. Children with poor communicating skill may need more aggressive analgesia in the emergency department.

A 3-year-old boy presented to our emergency department with a 3-week history of pain in the bilateral hip and abdomen that had persisted through antibiotic therapy based on diagnosis of acute osteomyelitis. At presentation, he had fever, anemia, and increased concentration of lactate dehydrogenase. After the identification of a left adrenal mass indicating neuroblastoma on computed tomography scan, he was admitted to the hospital by a pediatric oncologist. Subsequently, positron emission tomography and bone scintigraphy showed disseminated metastasis to the bone and bone marrow, and neuroblastoma was pathologically confirmed. This case highlights the importance of differential diagnosis of non-traumatic hip pain in toddlers considering the protean manifestations of neuroblastoma.

OBJECTIVES: This study investigated patients with oral and maxillofacial lacerations who visited the emergency room over a three-year period in an effort to determine the optimal treatment for these injuries. MATERIALS AND METHODS: This study examined 1,742 patients with oral and maxillofacial lacerations with 2,014 different laceration locations who visited the emergency room of Pusan National University Hospital (Busan, Korea) over three years, from January 2011 to December 2013. Patients were classified by sex, age, visit day, cause of injury, injury site, and the presence or absence of soft tissue and tooth injuries. RESULTS: The male to female ratio was 2.50:1. Patients under 10 years old were seen most frequently. Most emergency room visits were on weekends. Among intra-oral lacerations, the lip area was the most vulnerable site; among extra-oral lacerations, the chin area was most frequently injured. The most frequent etiology was a slip down. Most lacerations occurred without bone fracture or tooth damage. CONCLUSION: Laceration may differ in large part as compared with the fracture. Therefore, it is necessary to continue collecting data on oral and maxillofacial lacerations to establish optimal emergency room diagnosis and treatment strategies.

Aplastic anemia (AA) is a rare complication of liver transplantation. The causes of AA have not yet been identified, and optimal treatment for AA after liver transplantation has not been firmly established. We experienced two cases of AA accompanied with fulminant hepatitis among 157 pediatric recipients (1.3%) and among 17 recipients of Korean Network of Organ Sharing (KONOS) status 1 (11.8%). The patients were a 16-year-old girl and a 3-year-old boy who had jaundice and lethargy due to non-A, non-B, non-C fulminant hepatitis. The girl underwent split liver transplantation involving the liver of a 24-year-old man, and the boy underwent an emergency living donor liver transplantation with a liver obtained from his 16-year-old cousin. Each transplantation procedure was uneventful. However, both patients were diagnosed with AA caused by thrombocytopenia and neutropenia at 140 and 26 days, respectively, after liver transplantation. The girl recovered completely after undergoing bone marrow transplantation and was followed up for 70 months. However, the boy was conservatively treated because of the development of hyperbilirubinemia and pyrexia. He died of multi-organ failure 74 days after liver transplantation. AA is not a rare complication of pediatric liver transplantation for fulminant hepatic failure. Therefore, AA must be suspected in pediatric cases of cytopenia even after liver transplantation. Our findings indicate bone marrow transplantation is the treatment of choice for AA even in cases where AA develops after liver transplantation.
