PURPOSE: Acute otitis media(AOM) has variable clinical symptoms and is diagnosed with injection, bulging, and decreased mobility of tympanic membrane. There are many misdiagnoses because children who are suspected of having acute otitis media are uncooperative during diagnosis with an otoscope. An inaccurate diagnosis of acute otitis media when using an otoscope results in wasted of medical resourses and increased tolerance to antibiotics. Therefore, this study was conducted to evaluate the usefulness of a video otoscope as a tool of diagnosis of acute otitis media. METHODS: Among 416 patients who visited Pundang Jesaeng Hospital Emergency Medical Center with a complaint of otalgia from 1 October 2002 to 30 September 2003, we studied 51 patients who were followed up at the otorhinolaryngology depatment. Emergency Medicine residents recorded the findings for tympanic membrane by using an otoscope and by using a video otoscope. we used kappastatistics to carry out a prospective study in which the accuracy of diagnosis of AOM was analyzed by comparison with the confirmed diagnosis by an otolaryngologic specialist. RESULTS: In this study, the number of males was 24 (47%) and that of females was 27 (53%). Of the 51 Patients, 22 (43%) presented with rhinorrhea, 15 (29%) with cough, 11 (22%) with sputum, 10 (20%) with fever, 8 (16%) with a sore throat, 7 (14%) with otorrhea, 4 (8%) with hearing difficulty, 3 (6%) with irritability, 3 (6%) with tinnitus, 3 (6%) with vomiting and 2 (4%) with dizziness. A comparison of the diagnostic accuracy of AOM between otolaryngologic specialist and residents in emergency department, when was undertaken by using kappa statistics, and a diagnostic agreement of 65% (kappa=0.28) for the otoscope, and 76 %( kappa=0.45) for the video otoscope. The diagnostic sensitivity of acute otitis media by video otoscope was 75%, and specificity was 82%. CONCLUSION: When the tympanic membrane of the patient suspected of a having AOM is examined in an emergency medical center, video otoscopy should be a useful diagnostic tool for AOM owing to its high diagnostic accuracy.

PURPOSE: At the Emergency Department (ED), echocardiography of patients with chest pain, dyspnea, and syncope is essential to identify the underlying etiology such as acute coronary diseases or other cardiac diseases. Therefore, we studied the accuracy and the clinical value of echocardiography for use by the emergency physician as a tool for the identification and evaluation of cardiac diseases. METHOD: From first, September, 2003 to first, November, 2003, we collected the case histories of 40 patients with suspected cardiac diseases, on whom formal echocardiography had been performed within 2 hours after their initial ED echocardiography. The emergency physicians had a 4-hour didactic training course by cardiologists and 1 month of practical training at a formal echocardiography center, then, they performed the echocardiography using an Acuson ASPENT M ultrasound system with a 3.5-MHz phased-array transducer. Data from the emergency physicians and from the formal echocardiographers were analyzed using the wilcoxson sign test, and the correlation coefficient and p value were calculated. RESULT: There were 28 male patients (70.0%) and 12 female patients (30.0%) and the average age of all patients was 60.9+/-15.5 years. The left ventricular end diastolic diameters (LVEDD) from ED and formal echocardiography were, respectively, 44.6+/-7.9 mm and 48.7+/-6.6 mm (p=0.000), the interventricular septum thicknesses (IVS) were 11.6+/-3.6 mm and 10.9+/-3.0 mm (p=0.064), the left ventricular posterior wall thicknesses (LVPW) were 10.9+/-3.4 mm and 10.1+/-2.00 mm (p=0.178), the ejection fractions (EF) were 59.7+/-15.8% and 60.0+/-16.4%(p=0.312), the left atrium diameters were 36.5+/-6.3 mm and 37.0+/-5.8 mm (p=0.770), the aortic root diameters were 29.2+/-4.0 mm and 33.6+/-3.7 mm (p=0.001), and the inferior vena cava diameters (IVC) were 15.9+/-8.1 mm and 13.3+/-2.5 mm (p=0.444). Except for the LVEDD and the aortic root diameters, there were no significant differences between ED and formal echocardiography, and the presences of regional wall motion abnormalities (RWMA), relaxation abnormalities, right atrium enlargement (RAE), and right ventricle abnormalities were all concordant between the two groups. The correlation coefficients and the p values between ED and formal echocardiography were, respectively, 0.806 and 0.000 for LVEDD, 0.662 and 0.000 for IVS thickness, 0.725 and 0.000 for LVPW thickness, 0.922 and 0.000 for EF, 0.729 and 0.001 for left atrium diameter, 0.331 and 0.037 for aortic root diameter, and 0125 and 0.443 for IVS diameter. CONCLUSION: We suggest that ED echocardiography, like formal echocardiography, with additional focused training can measure and assess the structural and the functional parameters of the heart.

PURPOSE: This study was performed to determine whether the anion gap, the base excess, the lactate, and the strong ion gap obtained in the emergency department correlate with the prognosis and whether the strong ion gap is the most useful marker compared to the prognostic ability of the anion gap, the base excess, and the lactate. METHODS: We reviewed the records of 106 patients admitted to the intensive care unit via the emergency department. We measured the anion gap, the base excess, and the lactate and we calculated strong anion gap by using a formula. We divided the patients into survivors and nonsurvivors and compared the prognostic abilities of the four variables by using the Student's t-test and receiver operator characteristic curves. RESULTS: The mean age of the patients was 67+/-14, and the numbers of males and females were similar (58 males vs 48 females). The number of survivors was 92 (86.7%), and that of nonsurvivors was 14 (3.2%). The anion gap ( 24.8+/-8.8 vs. 16.4+/-4.8 mmol/L, p value=0.000), the base excess (-11.9+/-8.7 vs. -3.49+/-6.5 mmol/L, p value = 0.001), the lactate (9.1+/-7.7 vs. 4.5+/-3.1 mmol/L, p value = 0.011 ) and the strong ion gap (16.6+/-3.6 vs. 10.9+/-3.7, p value=0.000) of the nonsurvivors were higher. All of the four varibles were associated with the prognosis, but among them, the strong ion gap discriminated most strongly with an area under the receiver operator characteristic curve of 0.866 (95% confidence interval, 0.787 to 0.92). CONCLUSION: The initial emergency-department acid-base variables, the anion gap, the base excess, the lactate and the strong ion gap have prognostic abilities, but the strong ion gap is the variable that most strongly predicts of mortality.

PURPOSE: There have been few studies of bee-sting anaphylaxis in patients visiting the Emergency Department. Thus, this study was performed to observe the general characteristics and the various clinical presentations of beesting anaphylaxis. METHODS: The study was performed for two years between January 2001 and December 2002. The objects of the study were 42 patients who were diagnosed as having anaphylaxis due to bee stings among patients who visited Pundang Jae-Saeng Hospital's Emergency Department. Emergency medicine residents directly followed the beesting anaphylaxis protocol. RESULTS: Males were 33 cases (78.6%), and female wewe 9 cases (21.4%). Severe anaphylaxis occurred in 25 cases (59.5%) and mild anaphylaxis in 17 cases (40.5%). The most frequent month was September with 12 cases (28.6%), and the most frequent place was the mountains with 15 cases (35.7% ). Of the 18 cases (42.9%) presenting with a prior bee-sting history, the incidence of severe anaphylaxis was 14 cases (77.8%) whilst of the 24 cases (57.1%) without any prior history, the incidence was 11 (45.8%)(p= 0.037). CONCLUSION: The history of a previous beesting is more related to the incidence of severe anaphylaxis, and of those patients presenting with systemic symptoms, the incidence rate of severe anaphylaxis is higher at 59.5%. Thus, it seems reasonable to treat patients presenting with systemic symptoms from bee stings or with a history of previous bee stings with early administration of epinephrine and to keep them under close observation.

PURPOSE: The purpose of this study is to report real life experiences of sorafenib therapy for hepatocellular carcinoma (HCC) in Korea, using a subset of data from GIDEON (Global Investigation of Therapeutic Decisions in HCC and of Its Treatment with Sorafenib; a large, prospective, observational study). MATERIALS AND METHODS: Between January 2009 and April 2012, a total of 497 patients were enrolled from 11 sites in Korea. Of these, 482 patients were evaluable for safety analyses. Case report forms of paper or electronic version were used to record safety and efficacy data from all patients. RESULTS: More patients of Child-Pugh A received sorafenib for > 8 weeks than did patients of Child-Pugh B (55.5% vs. 34.3%). Child-Pugh score did not appear to influence the starting dose of sorafenib, and approximately 70% of patients both in Child-Pugh A and B groups received the recommended initial daily dose of 800 mg (69.0% and 69.5%, respectively). The median overall survival (OS) and time to progression (TTP) were 8.5 months and 2.5 months. In Child-Pugh A patients, the median OS and TTP were 10.2 months and 2.5 months. The most frequent treatment-emergent drug-related adverse event was hand-foot skin reaction (31.7%), followed by diarrhea (18.0%). The incidence of treatment-emergent adverse events was similar in both Child-Pugh A (85.4%) and Child-Pugh B (84.8%) patients. CONCLUSION: Sorafenib was well tolerated by Korean HCC patients in clinical settings, and the safety profile did not appear to differ by Child-Pugh status. Survival benefit in Korean patients was in line with that of a previous pivotal phase III trial (SHARP).
