OBJECTIVES: The aim of this study was to develop a Mental Health Questionnaire for Adults (MHQ-A) and investigate its validity and reliability. METHODS: A 73-item questionnaire was developed or selected by seven psychiatrists and a clinical psychologist. The questionnaire was administered to 351 subjects in Seoul and Gyeonggi area. The construct validity was investigated by performing principal component analysis, and the reliability was assessed in terms of the internal consistency using Cronbach's alpha. RESULTS: Principal component analysis revealed 15 factors underlying the psychiatric disorder and symptom category. Taken together, these 15 factors accounted for 64.023% of the common variance. Cronbach's alpha was high, indicating that the reliability of the questionnaire was satisfactory. Every category showed a positive correlation with most psychological measures. CONCLUSION: These results indicate that the MHQ-A is a reliable and valid scale for assessing psychiatric disorders. Although there were many limitations, the present study has significance as the basis of future research.

OBJECTIVES: The aim of this study was to develop a brief schema questionnaire for adults (BSQ-A) and investigate its validity and reliability. METHODS: A 36-item questionnaire was developed or selected by six psychiatrists. The questionnaire was administered to 209 subjects in Seoul and Gyeonggi area. The construct validity was investigated by performing principal component analysis, and the reliability was assessed in terms of the internal consistency using Cronbach's alpha. RESULTS: The principal component analysis revealed 18 factors underlying 18 early maladaptive schemas (EMSs). These 18 factors accounted for 87.488% of the common variance. The Cronbach's alpha was high, indicating that the reliability of the questionnaire was satisfactory. Every schema showed a positive correlation with most psychological measures. CONCLUSION: The results indicate that the BSQ-A is a reliable and valid scale for assessing EMSs. Although there are many limitations, the present study is expected to form the basis of future research.

BACKGROUND: Primary gastrointestinal lymphoma is one of the most common extranodal lymphomas. The purpose of this study was to collect information on the clinical features and treatment of patients with primary gastrointestinal diffuse large B-cell lymphoma (DLBCL) at a single healthcare facility in Korea. METHODS: Between May 1998 and December 2003, 76 primary gastrointestinal DLBCL patients at Asan Medical Center were identified and evaluated. RESULTS: Male patients accounted for 40 cases. The median age was 53 years. A total of 38 patients had primary gastric DLBCL. With a median follow-up of 25 months, the five year overall survival (OS) rate was 61.4% and the five year event free survival (EFS) rate was 59.3%. B symptoms, performance status, LDH levels and involved sites did not affect survival. Twenty-seven patients who underwent primary surgical resection did not demonstrate a difference in survival when compared to patients who did not undergo surgery. However, for intestinal lymphoma, primary surgical resection had a significant influence on EFS (p=0.030). Age (p=0.038), sex (p=0.017), stage (p=0.048), and the number of extranodal sites (p=0.002) were significant factors for EFS. The three year EFS rate for each International Prognostic Index (IPI) risk group was as follows: 78.4% for low risk, 63.7% for low-intermediate risk, 30.0% for high-intermediate risk and 0% for high risk (p=0.002). Cox multivariate analysis revealed that the IPI was the only independent prognostic factor for EFS (p=0.002). CONCLUSIONS: Here we report on the unique pattern of clinical features of primary gastrointestinal DLBCL from a single healthcare center in Korea. The IPI system had prognostic value for primary gastrointestinal DLBCL.

The purpose of the present study was to evaluate the histologic results of bone cavities that were surgically created in the calvaria of rabbit and filled with HA/beta-TCP composite powders, which had been developed in Korea (Dentium, Korea). Ten young adult rabbits were used. Four defects were surgically produced in calvaria of each rabbit. Each rabbit was anesthetized with Ketamine-HCl (5 mg/kg, Yuhan Cor. Korea) and Xylazine-HCl (1.5 ml/kg, Yuhan Cor. Korea)). An incision was made to the bony cranium and the periosteum was reflected. Using a trephine bur (external diameter: 8 mm, 3i, USA), 4 'through-and-through' bone defects were created with copious irrigation, and classified into 4 groups: control group: no graft materials, experimental group I: normal saline + graft materials: experimental group II: venous blood + graft materials: experimental group III: graft materials only. The defects were randomly filled with graft materials. The defects were closed with resorbable suture material. At the end of the surgical procedure, all animals received a single intramuscular injection of antibiotics Gentamicin (0.1 mg/kg, Dae Sung Microb. Korea). Rabbits were sacrificed with phentobarbital (100 mg/kg) intravenously at 1-, 2-, 4-, 6- and 8-week after. Specimens were treated with hydrochloric acid decalcifying solution (Fisher Scientific, Tustin, CA) and sectioned by bisecting the 8 mm diameter defects. The histologic specimens were prepared in the general method with H & E staining at 6 micrometer in thickness. The results were as follows; 1. New bone formation showed from after 2-week of surgery in defect area. As time lapsed, lots of new bone formation and mature bones showed. 2. Histologically, degree of new bone formation could not be discerned among the experimental groups. But, for experimental group II, lots of cells gathered around graft materials after 1-week of surgery, new bone formed slightly faster and than the others at 1-week after. For experimental group I, a few inflammatory finding showed around graft material at after 1-week and after 2-week of surgery. 3. No bone formation did show for control group. Based on histologic results, the new HA/beta-TCP composite powders appeared to act as a scaffolding material for regeneration of osseous defects.

The lung is the most common site for the metastasis of extrapulmonary malignant tumors. However, endobronchial metastases (EBM) from extrapulmonary malignant tumors are rare. The most common extrathoracic malignancies associated with EBM are the breast, renal and colorectal carcinomas. Lung metastasis from prostate cancer is often encountered but EBM is rare. We report a 74-year old man with endobronchial metastases from prostatic carcinoma presented with cough. The diagnosis of prostatic cancer and the endobronchial metastasis were confirmed by immunohistological staining with the prostate specific antigen. Hormonal therapy (lutenizing hormone releasing hormone agonist) was applied to this patient.

In off-pump coronary artery bypass grafting (CABG), multiple proximal anastomosis may increase the risk of cerebral embolism (air, debris) and aortic injury (dissection, pseudoaneurysm). Radial artery (RA) has no intraluminal valve such as saphenous vein. We applied Cabrol technique using aortic root replacement for proximal anastomosis in off-pump CABG. Cabrol technique using RA graft can reduce numbers of proximal anastomosis and reduce number of aortic manipulation in off-pump CABG. We report a Cabrol technique for proximal anastomosis in off-pump CABG with RA graft.

Obstructive intracardiac lesions, like mitral stenosis or insufficiency (MR), by myxomas of the left atrium have been commonly reported, but the attenuation of MR by myxoma combined with coronary artery disease is very rare. We report a 70-year-old female patient whose left atrial myxoma had attenuated moderate MR to mild MR and required mitral valve surgery after removal of the myxoma. She also had coronary artery disease, severe pulmonary hypertension and moderate tricuspid regurgitation due to the mitral valve lesions obstructed by myxoma. The patient underwent removal of myxoma, mitral and tricuspid valve reconstructions, and coronary artery bypass grafting. She was discharged at the postoperative 14 day without any problems.

Three cases of synchronous carcinomas of endometrium-fallopian tube, endometrium-cervix and endometrium-ovary are reported. Case 1 is endometrial endometrioid adenocarcinoma with FIGO stageIb, Grade 2 and tubal serous adenocarcinoma with FIGO stage Ib, Grade 2. Case 2 is endometrial serous carcinoma with FIGO stage Ilb and squamous cell carcinoma with FIGO stage Ial. Case 3 is endometrial endometrioid adenocarcinoma with FIGO stage Ia, Grade 1 and ovarian mucinous adenocarcinoma with FIGO stage IIIa, Grade 2. There is much confroversy with respect to staging and management of such cases since these tumors may represent either two synchronously occuring primaries or single primary with metastases. It is suggested that when each tumor is different histological subtype the tumors may be considered as two separate primaries and treatment may be less aggressive. It may be a favorable prognosis. The authors present three cases of synchronous carcinomas with a review of literature.
