BACKGROUND: ST segment elevation in patient with chest pain was seen in acute myocardial infarction and in numerous other non-infarction syndrome. The causes of non-infarction syndrome were left ventricular hypertrophy, BER(benign early repolarization), and left bundle branch block in cardiac origin and were hyperkalemia and hyperventilation syndrome in metabolic origin and were others. Furthermore, the differentiation of electrocardiogram between acute myocardial infarction and non-infarction syndrome was very difficult. So, we compared and analysed characteristics of ST segment elevation of acute myocardial infarction and non-infarction syndrome that suggested the clue of early diagnosis of coronary artery disease. METHOD AND MATERIALS: We retrospectively reviewed the electrocardiogram of 961 patients with chest pain who visited the emergency center from January 1999 to December 1999. Acute myocardial infarction was diagnosed by clinical finding, electrocardiogram, cardiac enzyme, echocardiogram, and myocardial spect. Left ventricular hypertrophy, BER, and left bundle branch block in cardiac origin of non-infarction syndrome were diagnosed by electrocardiographic criteria suggested by William J. Brady. Acute myocarditis, acute pericarditis, and hyperventilation syndrome were diagnosed by clinical finding. RESULTS: Among 961 patients with chest pain, 236(24.6%) patients manifested ST segment elevation who were diagnosed acute myocardial infarction in 162(68.6%) patients and non-infarction syndrome in 74(31.4%) patients. The causes of non-infarction syndrome in 74 patients were left ventricular hypertrophy(32:13.6%), BER(28:11.9%), left bundle branch block(11:4.7%), and others(3:1.3%). Three others were acute myocarditis, acute pericarditis, and hyperventilation syndrome. Electrocardiographic characteristics of ST segment elevation of non-infarction syndrome manifested almost same finding compared to William J. Brady' criteria. CONCLUSION: ST segment elevation in patient with chest with chest pain visited emergency department was seen in acute myocardial infarction(68.6%) and the other non-infarction syndromes(31.4%). Significant number of patients were not associated with acute myocardial infarction. Therefore, we must completely understand characteristics of ST segment elevation in acute myocardial infarction and the other non-infarction syndromes to diagnose fatal early coronary artery disease and to avoid unnecessary thrombolytic therapy.

OBJECTIVE: The purpose of this study was to evaluate the effects of malocclusion on the self-esteem of female university students. METHODS: The subjects were composed of 67 female university students who showed Class I molar relation, no missing or supernumerary teeth and has had no orthodontic treatment experience. Each subject was evaluated with Rosenberg's Self-esteem Scale to measure the level of self-esteem and also evaluated the degree of anterior crowding and lip protrusion through model analysis and cephalometric soft tissue profile analysis. RESULTS: The results showed that a protrusive profile and crowding of upper anterior teeth had significant reducing effects on the level of self-esteem. The protrusion and crowding groups showed no significant differences in self-esteem between groups. CONCLUSIONS: Malocclusion had significant negative effects on the self-esteem of female university students. Further research to investigate the negative psychological influence of malocclusion and the education of lay people about this influence is necessary.

Objective: The treatment outcomes of ruptured intracranial aneurysms using the Neuroform Atlas stent were evaluated. Methods: This study represents a retrospective review that included patients who underwent endovascular treatment for ruptured aneurysms at a single institution. Between January 2018 and September 2022, endovascular treatments including simple coiling or Neuroform Atlas stent-assisted coil embolization were performed in 191 patients with ruptured intracranial aneurysms. Results: Intraprocedural rupture was observed in 11 (8.7%) patients in the Simple Coiling (SC) group, which was slightly higher than that in 4 (6.3%) patients in the Neuroform Atlas stent-assisted coiling (NASAC) group (p=0.241). However, Thromboembolic event (TEE) was slightly more prevalent in the NASAC group, with 4 (6.3%) cases as compared to the 5 (3.9%) cases in the SC group (p=0.235). The retreatment rate was slightly higher in the SC group, with 19 (26.4%) patients as compared to the 10 patients (22.2%) in the NASAC group (p=0.342). Conclusions The use of the Neuroform Atlas stent (NAS) for ruptured aneurysms might be safe and effective.

Bilateral diaphragmatic paralysis(BDP) is a rare disorder, which can be secondary to spinal cord injury, motor neuron disease, myopathy, noninfectious polyneuropathy, infection, iced saline cardioplegia performed during cardiac surgery, or idiopathic causes. there may be typical presentations such as dyspnea, paradoxical respiratory movement, and hypercapnic respiratory failure. It needs to exclude above secondary causes to consider idiopathic bilateral diaphragmatic paralysis. We report a 51-years-old man who presented with idiopathic bilateral diaphragmatic paralysis combined with acute pancreatitis. We couldnt, find out the association of these two clinical conditions. The patient was improved by mechanical ventilation.
