We present a case of acquired tracheoesophageal fistula (TEF) which was found during induction of general anesthesia for clipping of aneurysm. The patient had been intubated with endotracheal tube for 10 days and then done tracheotomy for 45 days. Thereafter, TEF was confirmed by MRI and treated with fistula repair and tracheal fenestration. Acquired TEF can occur under the condition of prolonged tracheal intubation with high cuff pressure (>30 mmHg) and can also result from intratracheal neoplasm, mediastinitis, and other tracheal or esophageal damages. If unrecognized during anesthetic induction, TEF can cause gastric dilatation and rupture, pulmonary aspiration and respiratory failure. So early diagnosis and proper management is very important whenever TEF is suspected during anesthetic induction.

PURPOSE: The purpose of this study was to identify effects of a self-management program on self-efficacy and compliance in patients with CHF. Hypothesis: 1) Patients with CHF who are provided with a self-management program will show higher self-efficacy scores than a control group. 2) Patients who are provided with a self-management program will show higher compliance scores than a control group. METHOD: This study was designed as a nonequivalent non-synchronized pre-posttest control group. There were eight patients in the experimental group, and twelve in the control group. According to NYHA classification, all patients belonged under the classesl to lV. Data were collected using the instruments developed by the researchers. Data were analyzed using descriptive statistics and Mann Whitney U test. RESULT: There were significant differences in self-efficacy scores and compliance scores between the experimental and control group. CONCLUSION: By utilizing the program, patients were able to monitor their symptoms routinely, comply with therapeutic regimen, and feel better able to positively influence their disease. Therefore, better compliance means fewer readmissions of patients with CHF.

The purpose of this study was to determine the impact of situational, clinical and psychsoical factors on treatment-seeking behavior among those with acute myocardial infarction(AMI). This study used a retrospective, descriptive design. The sample consisted of 72 patients aged over 30 and who were diagnosed with an acute myocardial infarction at two large university-affiliated medical centers from July 1, 1998 to March 30, 2000. But of 72, patients 5 who were an outlier in treatment-seeking time were deleted. Data were collected by using questionnaires, which included demographic data, situational, clinical and psychosocial data. Also patient interviews and chart review were used to obtain information related to treatment-seeking time. The results of this study were summarized as follows; 1. Mean time from the onset of AMI symptoms to arrival at the hospital was 12.09 +/- 11.44 hours; 2. Treatment-seeking time was not significantly different by age, gender, or education; 3. Most(44 or 65.78%) patients were at home when they began having AMI symptoms. The remaining patients were either in a public area, workplace or in a car. Patients at home delayed longer than those who had their first symptoms elsewhere, but not significantly different. Also, most patients were with another person when they began to experience AMI symptoms: a spouse(25 or 37.3%), other family member(31 or 46.3%); the remaining 11 were alone. There were no significant differences in treatment-seeking time based on whether alone or with others. Most patients(46 or 68.7%) used an ambulance rather than taking private transportation, and patients who used an ambulance were delayed longer than those who used private transportation, but there were no significant differences; 4. Time to treatment-seeking was not significantly different by blood pressure, heart rate on admission and the peak CK-MB, CPK and Cholesterol level, Killips class; 5. There were no significant statistical differences in treament-seeking times by anxiety level, mood status or control ability.

Objective: : The purpose of this study was to suggest that computed tomography angiography (CTA) is valuable as the only preliminary examination for mechanical thrombectomy (MT). MT after single examination of CTA including non-contrast computed tomography (NCCT) and maximum intensity projection (MIP) improves door-to-puncture time as well as results in favorable outcomes. Methods: : A total of 157 patients who underwent MT at Dong Kang Medical Center from April 2015 to March 2019 were divided into two groups based on the examination performed prior to MT : CTA group who underwent CTA with NCCT and MIP, and NCCT+magnetic resonance image (MRi) group who underwent MRI including perfusion images after NCCT. In the two groups, time to CTA imaging or NCCT+MRi imaging after symptom onset, and time to arterial puncture and reperfusion were characterized as time-related outcomes. The evaluation of vascular recanalization after MT was defined as a modified thrombolysis in cerebral infarction (mTICI) scale. National Institutes of Health Stroke Scale (NIHSS) was assessed at the time of the visit to the emergency room and modified Rankin Scale (mRS) was assessed after 90 days. Results: : Typically, there were 34 patients in the CTA group and 33 patients in the NCCT+MRi group. A significantly shorter delay for door-to-puncture time was observed (mean, 86±22.1 vs. 176±47.5 minutes; p<0.01). Also, a significantly shorter door-to-imege time in the CTA group was observed (mean, 13±6.8 vs. 93±30.8 minutes; p<0.01). Moreover, a significantly shorter onset-to-puncture time was observed (mean, 195±128.0 vs. 314±157.6 minutes; p<0.01). Reperfusion result of mTICI ≥2b was 100% (34/34) in the CTA group and 94% (31/33) in the NCCT+MRi group, and mTICI 3 in 74% (25/34) in the CTA group and 73% (24/33) in the NCCT+MRi group. Favorable functional outcomes (mRS score ≤2 at 90 days) were 68% (23/34) in the CTA group and 60% (20/33) in the NCCT+MRi group. Conclusion : A single-phase CTA including NCCT and MIP images was performed as a single preliminary examination, which led to a reduction in the time of the procedure and resulted in good results of prognosis. Consequently, it is concluded that this method is of sufficient value as the only preliminary examination for decision making.

PURPOSE: Thoracic ultrasonography (US) is an emerging tool for diagnosing pneumothorax (PTX), and the possible application of color Doppler to ultrasonography is another new development. The aim of this study is to analyze the possible contribution of color Doppler to thoracic US and to the estimation of pneumothorax volume. METHODS: Patients who were admitted to emergency department underwent chest X-ray and thoracic US with color Doppler. They were also evaluated by computed tomography, if needed, US was performed at four chest sites by emergency medicine faculty and resident, and concordance between color Doppler and lung sliding was analyzed. The number of sites with abnormal findings was correlated with the volume of PTX at each sites. Statistical analysis was performed with Pearson correlation. RESULTS: Sixty-three of 151 PTX cases were included in our study. The sensitivity of US was for PTX detection was 92.1% (58 of 63), and the concordance between color Doppler and lung sliding was 99.4%. The number of sites per patient with abnormal findings increased with the average volume of the PTX. The average PTX volume in the 5 cases with normal findings was 7.0%, which is a smallsized PTX. CONCLUSION: The use of color Doppler is not more accurate than lung sliding, but it may helpful in diagnosing PTX. The volume of a PTX is proportional to a patient's number of sites with abnormal US findings.

We reviewed charts of patients on the clinical characteristics and factors which affect the prognosis of surgical results in the 77 patients(77 eyes) who were diagnosed with rhegmatogenous retinal detachment and operated on and followed for at least 3 months postoperatively at Korea University Guro hospital. We evaluated the characteristics of rhegmatogenous retinal detachment in Korea by comparing with other reports on retinal detachment as well. The factors associated with anatomic success were the duration of retinal detachment and the prescence of proliferative vitreoretinopathy. High success rate was achieved when the duration was less than 1 month and there was no proliferative vitreoretinopathy. The factors associated with functional success included the duration of retinal detachment, proliferative vitreoretinopathy, preoperative refractive error and the degree of retinal detachment(P<0.05).
