PURPOSE: Kimura's disease is an inflammatory condition of unknown etiology which usually occurs in salivary glands and cervical lymph nodes. This study was undertaken to evaluate the radiologic characteristics of Kimura's disease using CT and MRI. MATERIALS & METHODS: We evaluated CT & MR of 10 patients with histologically proved Kimura's disease in the head and neck. Six males and four females between 16 and 58 years old (mean age, 37.6 years) were included. Contrast enhanced CT scan was performed in all, and spin-echo MRI was performed in 2 patients. RESULTS: Both CT and MRI demonstrated the distinctive sites of involvement that were major salivary glands (4 cases) and lacrimal gland (1 case), periglandular soft tissue (8 cases), and cervical lymph nodes (8 cases). Majority of soft tissue lesions were ill-defined with infiltration to adjacent fascial planes, but nodal lesions were relatively well-defined and homogenous. The lesions were iso-intense on Tl-weighted image and hyper-intense on T2-weighted image. All but a few nodal lesions showed variable degree of contrast enhancement on CT and MRI. CONCLUSION: In diagnosis of Kimura's disease, CT & MRI of head & neck, especially salivary glands, are useful. In cases of recurrent periglandular soft tissue mass with contrast-enhancing cervical lymphadenopathy in adult patients, Kimura's disease should be included in the differential diagnosis.

A 25-year-old 7 month pregnant woman with mitral stenosis was hospitalized because of life threatening hemoptysis dispite intensive medical treatment. Emergency mitral commissurotomy resulted in prompt cessation of hemorrhage and at nine months follows-up, the hemoptysis has not recurred. Mitral valve surgery appears to be consitently associated with rapid and sustained cessation of hemoptysis. Therefore, surgery should be considered in hemoptysis due to mitral stenosis, particulary when the danger of asphyxiation exists.

OBJECTIVES: The aim of this study was to identify mental health state of prisoners in correctional institutions and to develop strategies for improvement of the environment related to it. METHODS: This research included a total of 1700 inmates from three out of 50 prisons nationwide; Symptom Checklist-90-Revision (SCL-90-R), State-Trait Anger Expression Inventory, Beck Depression Inventory (BDI), the Korean Version of the Beck Scale for Suicide Ideation, and cut down, annoy, guilty, eye-opener were applied. Additional questionnaires were employed for investigation of inmates' experience of violence within the correctional facilities and to examine utilization of mental health service before and after their admission to correctional facilities. RESULTS: Fifteen percent of the participants attained SCL-90-R T-scores of 65 or higher, which suggested that these individuals had, or were at great risk of, mental illness. As the level of anger felt by the prisoners turned out to be lower than expected, BDI scores of 22 and higher were observed in 28.1% of the inmates, and 33.6% of the prisoners had suicidal ideation. In addition, 39.1% of the total inmates were diagnosed with alcohol abuse. Twenty-one percent of the prisoners were victimized in their correctional institutions; therefore, violence may be one of the potential factors leading to stress. However, only a small percentage of the inmates requested and received counseling as a help. CONCLUSION: Mental health state among prisoners was serious and undesirable. This finding emphasizes the dire need for a system for regular assessment and improvement.

Lymphoma is the second most common neoplasm in the head and neck, and is the most common cause of unilateral neck mass in patients between 21 and 40 years of age. This report is a retrospective review of histologically proven lymphomas in 42 patients regarding histologic type, clinical stage, and CT imaging patterns. CT imaging plays an important role in making diagnosis, planning treatment, and evaluating recurrence after treatment. CT imaging patterns are classified into 4 types: Type 1 is nodal lymphoma, Type 2 extranodal lymphoma, Type 3 combined nodal and extranodal lymphoma, and Type 4 multifocal extranodal lymphoma. In conclusion, Lymphoma should be considered when multiple, nonnecrotic, homogenous lymph nodes are located in deep lymphatic chains (especially when they are large and bilateral or when both are the superficial and deep lymph node chains are involved simultaneously) and no mucosal abnormality of the aerodigestive tract is observed. Additionary, when a large nasopharyngeal mass lesion shows limited or equivocal bone destruction or a mass is identified on two sides of a nasal bone without frank destruction and when multiple sites of disease are identified in extranodal tissues.

BACKGROUND: Identifying problems and making a surgical plan through a preoperative analysis is important in facial aesthetic surgery. Thus, popular conceptions of an attractive face must be analyzed beforehand. The landmarks used as reference points may change after rhinoplasty, resulting in errors in the prediction and assessment of outcomes. To reduce such errors, it is advantageous to use reference points and landmarks that are subject to minimal variation. This study measured and analyzed landmarks with little preoperative and postoperative variation in rhinoplasty, and established appropriate standards for landmarks indicative of ideal profiles. METHODS: A photogrammetric analysis was performed of 80 famous and attractive celebrities from Korea, Southeast Asia, Japan, China, and America. The nasofrontal angle, nasal angle, nasolabial angle, angle of facial convexity, and angle of total facial convexity were measured. RESULTS: The angle of total facial convexity differed significantly among countries (P=0.013). No significant difference in nasal angle, facial convexity, or total facial convexity was observed between Western and Eastern countries. A significant difference in the nasofrontal angle (Asian: 138.66°, Western: 134.35°; P=0.006) was observed. The nasolabial angle (Asian: 97.09°, Western: 104.59° degrees; P=0.007) was significantly more acute in Asian than in Western subjects. CONCLUSIONS: In this study, we performed a more accurate analysis using the glabella instead of the nasion to measure the facial profiles of patients planning to undergo rhinoplasty and proposed standard values through an analysis of ideal and attractive facial profiles.

Cutaneous angiosarcoma is a rare, aggressive vascular malignancy with a grave prognosis. It usually arises in the scalp or face as a locally-advanced patch, plaque or tumor at presentation and most often affects males and the elderly. Histopathologically, well-differentiated angiosarcomas are composed of well- or ill-formed vascular channels, often lined by flattened atypical endothelial cells and are distinguished from benign counterparts by their so-called "collagen dissection pattern" and anastomosing architecture. Varied differentiation may be observed even in the same tumor. Epithelioid angiosarcoma is a rare variant of poorly-differentiated angiosarcoma. The patients were seven cases of angiosarcomas including an epithelioid variant. They were six males and one female with an age range between 65~84 years (avg. 74 years). Lesions resembled seborrheic dermatitis, erysipelas or "spreading bruise" that varied from blue to red in color and from papule to mass in size. They revealed satellite lesions far from the main lesion in some cases. Skin biopsies were performed for all patients and histopathologic features were compatible with angiosarcoma and epithelioid angiosarcoma. We herein report seven angiosarcomas of diverse clinical features because their early detection and precise differential diagnosis should be mandatory for effective management.

BACKGROUND: Quantitative measurement of hippocampal T2 relaxation time is an objective means of determining the frequency and severity of signal abnormalities. To evaluate the diagnostic properties of T2 relaxometry in temporal lobe epilepsy(TLE), we measured T2 relaxation time of bilateral hippocampi in pathology-proven TLE patients and normal controls. METHODS: We investigated 10 TLE patients who had temporal lobectomy with MR T2 relaxation mapping. All patients underwent in phase I or II studies, and had pathologic diagnosis. Also we measured T2 relaxation time in 10 normal volunteers. RESULTS: The pathologic findings of 10 TLE patients were followings: 8 hippocampal sclerosis (including dual pathology of necrotic granuloma), 1 calcified fibrous nodule, and 1 normal hippocampus. The mean T2 relaxation time of normal controls is 67.5msec, which is lower value than previous reports. All patients with hippocampal sclerosis in pathology showed increased T2 time greater than 2 SD of mean value of normal controls. But, the T2 values are upper normal range in non-hippocampal sclerosis. The lateralizing value of T2 relaxometry is 50% in TLE patients, and 62.5% in pathology-proven hippocampal sclerosis groups. CONCLUSIONS: There is a clear distinction of T2 relaxation time between the patients of hippocampal sclerosis and normal controls or non-hippocampal sclerosis. These findings suggest that the T2 relaxation time is a reliable objective measurement of hippocampal pathology, especially hippocampal sclerosis in TLE.

Bone marrow necrosis is infrequently diagnosed during life, and its presence often signifies a poor prognosis. It has been associated with a variety of disease, including acute and chronic leukemia, carcinoma, malignant lymph oma, infection and sickle cell disease. About 5-26% of acute myeloid leukemia has been reported to express lymphoid differentiation markers, of which CD7 is ex pressed very early during T-cell ontogeny. A 46-year-old male complaining severe bone pain had pancytopenia, leukoerythroblastosis and bone marrow necrosis. Peripheral blood immature cells expressed CD7 as well as myeloid markers such as CD13 and CD33 on immunophenotypic studies. We report a case of CD7 positive acute myeloid leu kemia associated with bone marrow necrosis, confirmed by bone marrow biopsy and immunophenotypic study.
