Background: High risks of fire alway exist for buildings in urban areas, especially those in downtown. Crowds, as well as more complex and larger structures, may cause more victims in the event of fire; therefore, emergency medical service plans must be established for such disastrous events. Methods: On the evening of October 30,1999, a fire broke out in downtown, Dong-Incheon Live-Hof restaurant; 56 people were killed and 76 were injured. Most of them were teenagers. We retrospectively reviewed the medical records of the victims, Results: 1) Among the 56 dead, 54 died from smoke inhalation, one from extensive burns, and one from sepsis during treatment. 2) Among the 76 injured, 70 patients suffered from smoke inhalation, 53 from burns, and 9 from several types of trauma (sprains, contusions, lacerations, abrasions, fractures, etc.). 3) Later complications were laryngeal edema, pulmonary edema, scar contracture, and hypoxic brain damage, and so forth. 4) Post traumatic stress syndrome was unexpectedly more prevalent in mildly to moderately injured survivors and witnesses than in seriously injured survivors. Conclusion: Many complications exist after a fire. Some may be resolved in time, but others may result in permanent sequelae. Early rescue, early triage, and early management during transport by emergency medical service (EMS) personnel can result in fewer complications and a lower mortality rate. Therefore, we propose the establishment of plans to be followed during various major disasters.

Background : Plants of Taraxacum spp. are widely used in medicine, but some of them have some problems related to propagation, such as strong dormancy and inactive germination. This study investigated the effects of temperature, gibberellic acid (GA3), and potassium nitrate (KNO3) on seed germination in Taraxacum ohwianum. Methods and Results : The seeds (NIBRGR0000135524) were exalbuminous, and their length and width were 4.25 ± 0.118 mm and 0.89 ± 0.062 mm, respectively. Among various temperatures (15, 20, 25, and 30℃), the optimum temperature for germination was found to be 20℃ (31.3%). High temperature (30℃) induced off-type in seedlings (thickened and crumpled cotyledons, and restricted root system). GA3 treatments increased germination percentage and speed, but germination percentage was higher with KNO3 treatment. Under KNO3 treatments (50 to 200 mg·L-1), germination percentage exceeded 80% after 12 days, with 50 mg·L-1 KNO3 being notably effective (91.2%, after 15 days). Conclusion : Seeds of T. ohwianum showed germination ability at low temperature. The best method for germination was pre-soaking in 50 mg·L-1 KNO3 (4℃, dark, 24 h) and incubating at 20℃ for 15 days.

Objective : The aim of this study was to determine the role of intra-arterial (IA) nimodipine injections for cerebral vasospasm secondary to ruptured subarachnoid hemorrhage (SAH) and to investigate the factors that influence vasodilation and clinical outcomes. Methods : We enrolled 29 patients who underwent aneurysm clipping for ruptured cerebral aneurysms between 2009 and 2011, and who received IA nimodipine after subsequently presenting with symptomatic vasospasm. The degree of vasodilation shown in angiography was measured, and the correlation between the degree of vasodilation and both the interval from SAH to cerebral vasospasm and the interval from clipping to cerebral vasospasm was determined. The change in blood flow rate after IA injection was assessed by transcranial Doppler ultrasound. Multiple clinical parameters were completed before and after IA nimodipine injection to evaluate any improvements in clinical symptoms. Results : For eight patients, Glasgow Coma Scale (GCS) scores increased by two or more points. The regression analysis demonstrated a positive correlation between the change in GCS scores after IA nimodipine injection and the change in blood vessel diameter (p=0.025). A positive correlation was also observed between the interval from SAH to vasospasm and the change in diameter (p=0.040); and the interval from clipping to vasospasm and the change in diameter (p=0.022). Conclusion : IA nimodipine injection for SAH-induced vasospasm led to significant vasodilation in angiography and improvement in clinical symptoms without significant complications. Our findings suggest that IA nimodipine injection should be utilized when intractable vasospasm develops despite rigorous conservative management.
불특정한 소화기계 증상으로 응급실에 방문한 소아에서의 혈청 Helicobacter pylori lgG 검사가 유용한가?

Purpose: Children visit the emergency department (ED) with more severe abdominal pain, nausea, and vomiting without specific cause than any other outpatients, and many have recurrent abdominal pain (RAP). For that reason, we examined the correlation between Helicobacter pylori (H. pylori) infection and these symptoms. Methods: From August 2001 to January 2002, serum samples of H. pylori IgG were collected prospectively from 90 children under 17-years old who had visited out ED with the above symptoms. Of these, 40 children satisfying Apley's criteria were researched. H. pylori infection was defined as a positive result on a CLO test or a C13-Urea Breath test or a modified Giemsa stain. Results: The male-to-female ratio was 1.5 : 1, and the mean age was 8.6±3.9 years old. The mean value of the IgG level was 16.1±22.2 U/mL. Seropositive patients accounted for 11 cases (28%). Of the 30 children who had undergone upper endoscopy, 15 children were confirmed as having an H. pylori infection. The sensitivity and the specificity of H. pylori IgG were 47% and 73%. In the school-age group (≥8 years old), the rates of IgG positivity and infection were 42% (10/24) and 70% (14/20), compared with the preschool age group value of 6% (1/16) and 10% (1/10). The most common upper endoscopy findings was nodular gastritis in 23 patients. Conclusion: The rate of H. pylori infection in children visiting the ED with unknown causes of above symptoms was higher than it was in a recent study. In ED, H. pylori IgG may be required as a screening test in such children.

Purpose: This study evaluated the prevalence of the metabolic syndrome (MetS) and risk factors for metabolic derangement in young adults with childhood-onset hypopituitary growth hormone deficiency (ACOHGHD). Methods: Thirty patients with ACOHGHD who were treated with hormone-replacement therapy, aged 18 to 29 years, who visited the Seoul National University Children's Hospital between September 2009 and February 2010 were enrolled. Height, weight, waist circumference, hip circumference, and blood pressure were measured, and the clinical and hormonal features were reviewed retrospectively. We evaluated measures of metabolic derangement in the enrolled patients and in the data of healthy adults aged 20 to 29 years taken from the 2005 Korean National Health and Nutrition Examination Survey (KNHANES) as part of the National Cholesterol Education Program-the Adult Treatment Panel III. Results: Compared with the KNHANES participants, patients with ACOHGHD had significantly large waist circumference (men and women), high systolic blood pressure (BP) (women) and diastolic BP (men), and high serum triglyceride levels (women). The duration of illness correlated significantly with central obesity ($r^2$=0.546, $P$=0.003). The prevalence of MetS was 10% in patients with ACOHGHD and 2.3% in KNHANES participants. The prevalence of central obesity and MetS was higher in patients with ACOHGHD than in KNHANES participants ($P$<0.001 and $P$=0.042, respectively). Conclusion: Abdominal obesity correlated with the duration of illness in patients with ACOHGHD. Waist circumference should be measured in the clinic to prevent MetS, particularly in patients with a long history of ACOHGHD, regardless of age or sex.
