BACKGROUND: To assess the incidence of venous thromboembolism (VTE) following shoulder surgery and to evaluate the role of postoperative duplex ultrasonography. METHODS: The study comprised a total of 224 patients who underwent shoulder surgery, including 180 shoulder arthroscopic surgeries, 28 shoulder arthroplasties, and 16 plate fixations for proximal humerus fracture between January 2014 and December 2014. The mean age of patients was 59.0 years, and there were 81 men and 143 women. Clinical data, including body mass index, blood tests, metabolic work-up for liver and renal function, previous, and present medical history, were evaluated. Duplex ultrasonography in the operative arm was performed on 2 to 4 days after surgery. RESULTS: The overall incidence of VTE following shoulder surgery was 0.45% (1/224). One patient with open reduction and plate fixation for proximal humerus fracture had asymptomatic deep vein thrombosis that showed complete remission after anticoagulant medication during a 2-month period. Four patients had asymptomatic superficial cephalic vein thrombosis and complete remission without any treatment. There was no case of pulmonary embolism. CONCLUSIONS: The incidence of VTE following shoulder surgery was extremely low in Asians. Duplex ultrasonography may be not considered a routine follow-up of shoulder surgery and can be selectively performed in high-risk or symptomatic patients for VTE.

PURPOSE: The number of suicide attempts has increased in Korea. Depressive disorders are a major cause. This study investigated the clinical characteristics and outcomes of attempted suicide victims who had been admitted to the emergency department based on a psychiatric disorder. METHODS: We performed a retrospective analysis of 168 suicide attempters who visited the Chosun University hospital emergency medical center between June 1st, 2007 and May 31st, 2008. From chart reviews, we divided the victims into three groups by psychiatric histories, especially depressive disorder. We analyzed the effect of various factors including age, sex, previous suicide attempts outcome of suicide attempts. We used Pearson's chi-square test to chart the statistical data. RESULTS: Depressive patients had significantly more suicide attempts than other psychiatric patients and more than those who had no psychiatric history. Repeated attempts were also more frequent in depressive patients (64%). Sixty percent of depressive patients were admitted into our hospital or local clinic and eight percent of depressive suicide attempters died. Compared to other national statistics, there were fewer persons who consulted with a psychiatrist, but depressive patients had more interviews with psychiatrists (62.9%) than did the other groups. CONCLUSION: Even if the depressive disorder patient group shows a high recurrence rate, it also shows a high psychiatric interview acceptance rate and a relatively low rank on physical and psychiatric severity. Therefore, it is possible to prevent the recurrence of suicide attempts for the depressive group and to reduce the fatality rate. This can be done through on-going educational opportunities and psychiatric interviews. The rate of psychiatric consultations in Korea are significantly lower than in other countries. This situation requires more active psychiatric consultations and interviews later on.

In order to determine the survival rate and prognostic factors of patients with intracranial oligodendroglioma as predictors of survival, a retrospective analysis of a total of 68 cases treated between 1982 and 1992 at our institute was performed. The 5-year and 10-year survival rates were 84.5% and 55.1% respectively while the median survival time was 116+/-5.3 months. The significant factors identified by the univariate analysis included the presence of preoperative seizure, the pre- and postoperative status, the presence of signs of increased intracranial pressure before operation and pathologic grade of the tumors. Factors such as age, types of chief complaints, blood types, the preoperative neurologic deficit, the size of tumor, the enhancement of tumor, cysts in tumor, the extent of removal and the postoperative seizure had no correlations with survival rates. The only significant prognostic factor determined by the multivariate analysis was the pathological grade(p=0.04).

A patient who was transferred to our Emergency Medical Center from a local clinic with a dermatologic disorder of unknown origin presented to us with TEN with a 40% skin slough. The patient was a 53-year-old women with complaints of erythematous rash and blisters on her trunk and both proximal extremities. She had taken NSAIDS, 1300 mg per oral, every 8 h for 5 days. Five days after administration of NSAIDS began, the doctors at the local clinic noted that a rash with blisters had begun on her back and progressed to her extremities. After 4 days of that progression she came to us. On physical examination, she had asymptomatic multiple clear filled bullae and erosion with brown- to black-colored hyperpigmentation on her trunk and proximal extremities involving 40% of the body surface. She was admitted to a private room to prevent secondary infections, and her management included fluid replacement, third-generation cephalosporin and corticosteroid administration, and intensive wound care. Fifteen days after admission, no further treatment was required, and only a small scar and a mild dispigmentation lesion could be seen. Emergency department physicians should think about TEN if the patient has extensive exfolating skin lesions. Treatment of patients with suspected TEN must be directed at minimizing fluid and electrolyte loss and preventing secondary infection, and an effort should be made to identify the suspicious drug and to educate patient to avoid the drug.

Some reports provide conclusive evidence of close interactive regulation between the taste receptor and sympathetic nervous system. We report a middle-aged male patient with gustatory change after cervical sympathetic ganglion block (CSGB) who had been suffering from hypersensitivity to sour taste since developing complex regional pain syndrome (CRPS) type 1, diagnosed according to the revised CRPS criteria. Despite receiving two high doses of prednisolone therapy, he experienced the recurrence of CRPS symptoms. We attempted other therapy treatments, including pamidronate intravenous infusion, non-steroidal anti-inflammatory drugs, opioids, tricyclic antidepressants, and CSGB. Following each CSGB administration, the patient reported decreased hypersensitivity to sour-tasting foods, such as kimchi and oranges, with decreased pain and reduction of dysautonomic symptoms. This case demonstrates that overactivation of the sympathetic nervous system may influence sensitivity and regulation of gustatory receptors; therefore, a patient demonstrating CRPS symptoms, including taste alterations, may respond positively to CSGB therapy.

As part of an initial inquiry into the function of the outer membrane proteins (OMPs) of Helicobacter pylori Korean strain 51, we have conducted an extensive proteome analysis via quadrupole time of flight (Q-TOF) mass spectrometry (MS). Fifty one OMPs of H. pylori were purified using sarcosine and resolved via two-dimensional electrophoresis with immobilized pH gradient strips. The most abundant proteins were observed in the alkaline pI regions (6.0~11.0) at molecular masses between 10~100 KDa. Here, 15 spots were identified, representing 9 types of genes (KHP0852, KHP0853, KHP1353, KHP1017, KHP0172, KHP0076, KHP0617, KHP1069, KHP0614) from the sarcosin-insoluble fraction of H. pylori 51. These may be employed in the characterization of the OMPs of H. pylori 51, which will help to identify new potential target proteins for vaccine development and drug therapy.

PURPOSE: Organophosphate insecticide poisoning is common in Korea, but there is no definitive guideline for determining the severity of the poisoning and the predictive factors. Therefore, we evaluated the organophosphate poisoned patients and we divided them into two groups, the survivors and the dead, and the results might be useful for treating organophosphate poisoning patients. METHODS: We performed a retrospective analysis of 68 organophosphate poisoned patients who visited the Chosun University Hospital Emergency Medical Center during a 24-month period from January, 2007 to December, 2008. We made a work sheet of the patients' characteristics and the collected data was analyzed and we compared this data between the survivor group and the dead patient group. RESULTS: There were significant differences between the survivor group and the dead patient group for the mean age, the alcohol intake state and the typically expressed signs. The dead patients had lower blood pressure, tachycardia and a lower Glasgo Coma Score (GCS) score than the survivor group. On the arterial blood gas analysis, the dead patients had more severe acidemia and they had lower saturations. Increased serum amylase levels were found in the dead patients. The survivors' initial and follow up serum pseudocholinesterase activity (after 6~8 days) was significantly higher than that of the dead group. The total amount of atropine injected to patient was less in the survivors than that in the dead patients. CONCLUSION: Old age and expressing the typical intoxication signs, a lower GCS score and blood pressure, showing acidosis on the gas analysis and low serum cholinesterase activity may be useful as poor prognostic indicators for patients with organophosphate poisoning. We suggest that physicians must pay careful attention to the signs and prognostic factors of organophosphate insecticide poisoned patients.

OBJECTIVE: Data mining extracts meaningful information from large datasets. In this study, text mining techniques were used to extract keywords from the Journal of the Korean Society of Emergency Medicine, and the change trend was examined. METHODS: The rvest package in R was used to extract all papers published in the Journal of the Korean Society of Emergency Medicine from 2006 to 2016 that could be searched online. Among them, 3,952 keywords were extracted and studied. Using the selected keywords, the corpus was formed by refining keywords that did not correspond to MeSH (Medical Subject Headings) or were misspelled and had similar meanings based on agreement of researchers. Using the refined keywords, the frequencies of the keywords in the first and second halves of the studies were calculated and visualized. RESULTS: Word Cloud revealed that emergency medical service and cardiopulmonary resuscitation (CPR) were most frequently mentioned in both the first and second halves of the studies. In the first half, ultrasonography, stroke, poisoning, injury, and education were frequently mentioned, while in the second half, poisoning, injury, stroke, acute, and tomography were frequently mentioned. A pyramid graph revealed that the frequencies of emergency medical service and CPR were commonly high. CONCLUSION: Core keywords of the Journal of the Korean Society of Emergency Medicine were analyzed for correlations and trends. Changes in study topics according to key topics of interest and period were visually identified.
