1.  Calcified amorphous tumor in left atrium presenting with cerebral infarction 
Journal of Thoracic Disease  2014;6(9):1311-1314.
Calcified amorphous tumor (CAT) of the heart is an extremely rare cardiac mass. We describe a case of cardiac CAT in a 70-year-old Korean female who presented with acute onset dysarthria and right side weakness. Echocardiography and chest computed tomography revealed a left atrial mass that originated from the interatrial septum. The patient underwent surgical resection and pathologic examination demonstrated CAT. Postoperative course was uneventful and she was followed without recurrence.

2.  A case of rapidly progressing leiomyosarcoma combined with squamous cell carcinoma in the esophagus 
Esophageal leiomyosarcoma is a rare tumor that accounts for less than 1% of all malignant esophageal tumors. Esophageal leiomyosarcoma combined with squamous cell carcinoma is even rarer than solitary leiomyosarcoma. We experienced a case of leiomyosarcoma combined with squamous cell carcinoma that progressed very rapidly.

3.  A Case of Patent Ductus Arteriosus with Congestive Heart Failure in a 80-Year-Old Man 
Korean Circulation Journal  2012;42(12):849-852.
Patent ductus arteriosus (PDA) is a rare clinical finding in adult patients. Considering the increase in cases of PDA discovered incidentally on echocardiograms at young ages, and the life-shortening effect of PDA, it is rare to diagnose PDA in old patients. We report a case of an 80-year-old patient who experienced symptoms of congestive heart failure showed findings suggestive of PDA in echocardiogram and confirmed the diagnosis through a cardiac catheterization and a coronary angiography. After percutaneous occlusion of PDA with an Amplatzer duct occlusion device, symptoms related to congestive heart failure improved.

4.  Endovascular treatment of ruptured infected aortic aneurysm with sepsis 
The generally accepted treatment for infected aortic aneurysms involves open surgical resection and debridement, with in situ or extra-anatomical bypass. Occasionally, endovascular management can be substituted for the standard operation dependent on the patient's condition. We report the case of an 81-year-old female with a ruptured infected aortic aneurysm and sepsis, successfully treated endovascularly. She had been on oral antibiotics for one year and is doing well 2 years after discharge.

5.  Massive Empyema Associated With Transient Hypogammaglobulinemia of Infancy and IgA Deficiency 
Journal of Korean Medical Science  2009;24(2):357-359.
Transient hypogammaglobulinemia of infancy (THI) is originally defined as a physiological maturation defect of immunoglobulin G (IgG) production that occurs at 3-6 months of age and lasts until 18 to 36 months of age. We report here on a 22-month-old child with THI and IgA deficiency, who had massive pneumococcal empyema. Her depressed IgG level returned to normal within 6 months, but IgA level was still low at 6 yr of age. Although THI is an age-dependent and self-limiting disorder, severe infection that includes an atypical presentation of an infection may occur in some patients and this requires evaluation with immunologic study.

6.  Intrapleural Chemotherapy with Cisplatin and Cytarabine in the Management of Malignant Pleural Effusion 
The purpose of this study was to evaluate the efficacy of intrapleural chemotherapy (IPC) with cisplatin and cytarabine in the management of malignant pleural effusion (MPE) from non-small-cell lung cancer (NSCLC).
Materials and Methods
A prospective analysis was carried out on 40 patients with pathologically proven MPE from NSCLC who had received IPC. A single dose of cisplatin 100 mg/m2 plus cytarabine 1200 mg/m2 in 250 ml normal saline was instilled into the pleural space via a chest tube and drained 4 hours later. Patients were evaluated for toxicities and responses at 1, 2, & 3 weeks and then at monthly intervals if possible. Systemic chemotherapy was administered, if the patient agreed to receive it, after achieving complete control (CC) of MPE.
The median duration of chest tube insertion for drainage was 7 (3~32) days. Among the assessable 37 patients, CC and partial control (PC) were 32 (86.5%) and 4 (10.8%) patients, respectively (overall response rate 97.3%). The median duration of response was 12 months (2~23) and there were only two relapses of IPC after achieving CC. Among the 35 patients who were assessable until they died, 28 patients (80.0%) maintained CC until the last follow-up. There was only one toxic death and the toxicities of IPC, versus the results obtained, were deemed acceptable.
The procedures were tolerable to the patients and chemotherapy-induced complications were at an acceptable level. The outcome of this trial indicates that IPC has a superior and long lasting treatment response in the management of patients with MPE from NSCLC.
