Giant cell myocarditis(GCM) is a rare inflammatory heart disease which is characterized by multinucleated giant cells and a granulomatous reaction. It usually progresses rapidly and results in a fatal course. We report a patient with giant cell myocarditis who was treated by cardiac transplantation. A 35-year-old male was admitted with dyspnea which had developed 4 months before. On echocardiography, the right and left ventricles were markedly dilated and severe global hypokinesia was noted. He was diagosed with dilated cardiomyopathy with secondary severe mitral regurgitation. His cardiac function deteriorated progressively. He underwent orthotopic heart transplantation. Grossly the heart was enlarged, weighing 420gm and round with a blunt apex. Both right and left ventricles were markedly dilated. There were numerous white patches, measuring up to 4cm, throughout the epi- and myocardium. Microscopically, extensive fibrosis and multiple exuberant granulomas with numerous scattered multinucleated giant cells were seen. Lymphocytes and eosinophils were also frequent. Coronary arteries were unremarkable. Neither microorganisms nor foreign materials were found. By serial endomyocardial biopsies of the transplanted heart, only mild perivascular lymphocytic infiltration was occasionally observed without any evidence of rejection or recurrence of giant cell myocarditis. The patient's postoperative course has been uneventful so far(postoperative 21 months). The etiology of GCM remains to be clarified, although various factors are suspected. No matter what the cause, our experience suggests that this grave disease might be treated well by heart transplantation.

We report a case of an accidental extravasation of contrast material. A large-volume extravasation occurred in an adult during spiral contrast-enhanced CT. The amount of contrast material extravasated was 47 ml. The patient had a swelling of the dorsum right hand. The extravasation injury site was determined by CT scanning. The extavasation case was examined using five separate display techniques: axial, multi planar reformation (MPR), maximum intensity projection (MIP), volume rendering, and shaded-surfaced display (SSD). This paper introduces extravasation with the CT and the three-dimensional appearance.

Delayed stenosis of the treated artery following mechanical thrombectomy is known to occur in approximately 10% of the patients after the procedure. It is usually asymptomatic, and was frequently found within 1 year after the procedure. Here we report a 58-year-old stroke patient who suffered from recurrent transient ischemic attacks due to a delayed stenosis of the middle cerebral artery 2 years after the mechanical thrombectomy for an abrupt embolic occlusion of the vessel.

The residual tense false lumen following surgical repair of aortic dissection remains one of the most difficult and challenging postsurgical problems. Percutaneous fenestration of the dissecting membrane under the guidance of intravascular ultrasound has been recently introduced to depressurize the tense false lumen. A 63-year-old woman who underwent repair of acute type I dissection was readmitted because of claudication and numbness of the left lower extremity. Angiography, computed tomography, and magnetic resonance imaging clearly showed a dissection flap starting from the thoracic aorta distal to the left subclavian artery. Compressed true lumen by the markedly enlarged tense false lumen was also noted in the double-channeled descending thoracoabdominal aorta. Under intravascular ultrasound guidance, the intimal flap was punctured with a Brockenbrough needle advanced to the true lumen through a femoral artery, and then, a balloon catheter was introduced over the guidewire which was placed across the dissection flap. Desired fenestration was obtained successfully by inflation of the balloon without complications. After procedure, symptoms resolved promptly and she is currently(clinical follow-up of 12 months postfenestration) ambulating without claudication. In conclusion, percutaneous fenestration of the intimal flap is a technically feasible and an effective alternative procedure to surgical repair for restoration of perfusion to an ischemic extremity in selected patients complicated with aortic dissection.

PURPOSE: To evaluate effectiveness of percutaneous transluminal angioplasty (PTA) for transposed brachiobasilic arteriovenous fistula (tBBAVF), and to analyze the factors influencing patency after PTA. MATERIALS AND METHODS: In 101 patients who underwent operation for tBBAVF from January 2006 to February 2008, we identified 42 patients undergoing PTA. We conducted a retrospective analysis of sequential PTAs in these patients from 2006 to 2017. RESULTS: A total of 100 PTAs were performed. The technical success rate was 93% and the clinical success was 100%. Only ruptures occurred in 12% as minor complications. Primary patency rate was 61%, 29%, 7%, and secondary patency was 91%, 82%, 59% at 6, 12, and 24 months, respectively. Primary patency rate was lower in tBBAVF with rupture (p = 0.024). Secondary patency rate was significantly lower in the diabetes (p = 0.002). CONCLUSION Repetitive PTAs in tBBAVF are acceptable due to excellent secondary patency. Primary patency of tBBAVF is low in patients with rupture. Diabetes itself has a significant effect on secondary patency.

An increasing number of studies have highlighted the impact of sleep on physical and mental health and a corresponding rise in public interest; numbers of polysomnography (PSG) examinations have correspondingly increased. However, research and recommendations concerning safety events that may occur during PSG are lacking. This study aimed to investigate the current status of safety events in sleep laboratories in Korea and gather expert opinions on this matter. Methods: We conducted a web-based survey of Korean sleep experts to explore their opinions on safety events in sleep laboratories. Results: All Korean sleep experts who participated in this study agreed on the need for guidelines concerning safety events that can occur during PSG. Through this survey, they provided insights into the cardiac and pulmonary safety events that may arise during PSG. Conclusions: This study can assist sleep physicians in managing safety events in sleep laboratories currently, and in the future, it may contribute to the development of guidelines for handling safety events during PSG.

OBJECTIVES: Korea is well known for its long work hours amongst employees. Because workers of the manufacturing industry are constantly exposed to extended work hours, this study was based on how long work hours affect their emotional well-being. METHODS: The analysis was done using the secondary Korean Working Condition Survey (KWCS). Long work hours were defined to be more than 48 hours, and they were subcategorized into units of 52 hours and 60 hours. Based on the WHO (five) well-being index, emotional state was subdivided into three groups - reference group, low-mood group, and possible depression group- where 28 points and 50 points were division points, and two groups were compared at a time. Association between long work hours and emotional state was analyzed using binary and multinomial logistic regression analysis. RESULTS: Working for extended working hours in the manufacturing industry showed a statistically significant increase (t test p < 0.001) in trend among the possible depression group when compared to the reference group and the low-mood group. When demographical characteristics, health behaviors, socioeconomic state, and work-related characteristics were fixed as controlled variables, as work hours increased the odds ratio of the possible depression group increased compared to the reference group, and especially the odds ratio was 2.73 times increased for work hours between 48-52 and 4.09 times increased for 60 hours or more and both were statistically significant. In comparing the low-mood group and possible depression group, as work hours increased the odds ratio increased to 1.73, 2.39, and 4.16 times, and all work hours from working 48-52 hours, 53-60 hours, and 60 hours or more were statistically significant. Multinomial logistic regression analysis also showed that among the reference group and possible group, the possible depression group was statistically significant as odds ratio increased to 2.94 times in working 53-60 hours, and 4.35 times in 60 hours or more. CONCLUSIONS: Long work hours have an adverse effect on emotional well-being. A more diversified research towards variables that affect long work hours and emotional well-being and how they interact with each other and their relationship to overall health is imperative.
