PURPOSE: The purpose of this study is to illustrate MR patterns of bone marrow of calvarium and vertebral body in normal subjects according the age distribution and to understand the course of the fatty replacement from red marrow. METHODS AND MATERIAL: We retrospectively evaluated MR examinations of the calvaria(n=71), cervical spine(n=71), thoracic spine(n=65), Imbar spine(n =68) in subjects without bone marrow abnormality whose age ranged 3 weeks to 74 years. Three distinctive patterns were categorized on Tl-weighted images of the skull. In pattern 1, uniformly low signal intensity with or without very small areas of high intensity in frontal and occipital bones is noted. In pattern 2, frontal and occipital bones have uniformly high signal intensity, and patchy area of high intensity appears in parietal bone. In pattern 3, the entire skull has uniformly high signal intensity. In the spine, four patterns were categorized on Tl-weighted MR images. In pattern 1, the vertebral body has uniformly low signal intensity except for linear areas of high intensity superior and inferior to basivertebral vein. In pattern 2, bandlike and triangular areas of high signal intensity are found in the periphery. Pattern 3 and 4 have diffusely distributed areas of high signal intensity; pattern 3 consist of numerous indistinct dots measuring a few millimeter or less, and pattern 4 consist of fairly well marginated areas ranging in size from 5 to 1.5cm. RESULT:In the calvaria, 73% of pattern 1 were younger than 20 years, pattern 2 were evenly distributed, and 86% of pattern 3 were older than 40 years. In the spine, 87% of pattern 1 were younger than 40 years, 72% of pattern 3 were in 40 to 50 years, and 87% of pattern 4 were older than 50 years. Pattern 2 were evenly distributed in the cervical and thoracic spine, but in the thoracic spine 62% were younger than 30 years. CONCLUSION:It is concluded that younger age group shows mainly pattern 1, whereas elderly group has pattern 3 or 4 in the calvarial and vertebral body marrow. This suggests that conversion to fatty marrow begin locally and progress diffusely with age.

The androgen insensitivity syndrome is a heterogeneous disorder with a wide spectrum of phenotypic abnormalities, ranging from complete female to ambiguous forms that more closely resembles males. Mutations of the androgen receptor gene are responsible for a variable degree of impaired androgen action. The complete androgen insensitivity syndrome is characterized by normal female external appearance in spite of the normal male karyotype 46XY with testes and normal testosterone production and metabolism. This is transmitted by X-linked recessive manner. Wolffian duct does not develop. However, m llerian development does not occur in presence of antim llerian hormone activity. Recently we experienced a case of complete androgen insenditirity syndrome. We reported a case with concerned literatures.

OBJECTIVES: The aims of this study were to evaluate acceptability and usefulness of the Korean version of Self-report Standardized Assessment of Personality-Abbreviated Scale (SAPAS-SR) as an instrument for screening patients with a personality disorder. METHODS: The Korean version of the SAPAS-SR was administered to a non-random sample of 186 psychiatric patients (155 patients with a personality disorder and 31 patients with no personality disorder). The International Classification of Diseases 10th version Personality Assessment Schedule was used as a gold standard in diagnosis of personality disorder. Receiver-operant-characteristics and validity indicators were determined. In addition, the SAPAS-SR was administered to 22 healthy men to examine the test-retest reliability. RESULTS: The area under the curve for the SAPAS-SR was 0.69 (95% confidence interval 0.59-0.79). The SAPAS-SR score of 4 or more correctly classified 67.2% of patients with a personality disorder. Sensitivity (0.67) and specificity (0.68) were slightly lower compared with the original English version. CONCLUSION: This study provides preliminary evidence of the usefulness of the Korean version of the SAPAS-SR as a self-administered instrument for screening personality disorders in the clinical population.

PURPOSE: The purpose of this study is to compare treatment response and survival according to treatment modalities, such as allogeneic bone marrow transplantation (BMT), combined immunosuppression and supportive care, and according to etiologies in children with severe aplastic anemia. METHODS: Thirty-four patients who had severe aplastic anemia received either BMT, combined immunosuppression, or androgen treatment at Chonnam University Hospital from Jan. 1990 to Mar. 1998. The clinical characteristics and response according to treatment modalities or etiologies were studied retrospectively. RESULTS: 1) Patients in Group 1 received combined immunosuppression of ALG/ATG+methylprednisolone+/-cyclosporin (N=18); Group 2, BMT (N=11); Group 3, supportive treatment of oxymetholone+prednisolone+transfusion (N=5). Clinical characteristics were not different among three groups. 2) In Group 1, the response rate was 50% with complete response (CR) in 4 (22.2%) and partial response (PR) in 5 (27.8%). CR was attained in 91% (10/11) of Group 2 patients, while all 5 in Group 3 were died. Relapse was found in 1 out of 9 (11.1%) in Group 1. Three of 10 in Group 2 who had initial response experienced late graft failure. The Kaplan-Meier 4-year-survival in each group was 75.5%, 81.8% and 20%, respectively (P = 0.019). 3) Among 5 patients were Fanconi's anemia, two survived who underwent HLA- matched sibling transplants. Three patients with secondary aplastic anemia, including posthepatitis (N=2) and post-rubella responded to either BMT or immune suppression. Idiopathic cases (N=26) showed response rate of 43.8% to immunosuppression [CR, 3/16; PR 4/16], 85.7% to BMT, and 0% to supportive care. 4) The relative risk of death was 0.26 (P = 0.052) in Group 1, and 0.15 (P = 0.03) in Group 2 in comparison with Group 3. CONCLUSION: The study showed that BMT and combined immunosuppression resulted in better response and survival than supportive care in the management of childhood severe aplastic anemia. Although BMT seemed to be better than immunosuppression, effective measure to reduce late graft failure and graft versus host disease should be pursued.

The autoinfective filariform larva of Strongyloides stercoralis causes hyperinfection in immunosuppressed hosts. Here we report on the case of a male patient who was admitted to the emergency room at Gwangju Veterans Hospital with a complaint of dyspnea, and who was receiving corticosteroid therapy for asthma. Many slender larvae of S. stercoralis with a notched tail were detected in Papanicolaou stained sputum. They measured 269 +/- 21.2 micrometer in length and 11 +/- 0.6 micrometer in width. The esophagus extended nearly half of the body length. The larvae were identified putatively as autoinfective third-stage filariform larvae, and their presence was fatal. The autoinfective filariform larva of S. stercoralis has not been previously reported in Korea.

Chromosomal abnormalities, which are valuable markers for diagnosis and prognosis of cancer, provide useful clues in characterizing cancer at molecular level. Gastric cancer is the major cause of cancer deaths in Asian countries, including Korea. Genetic changes during the progression and metastasis of gastric cancer remain unclear. Recently, technique of degenerate oligonucleotide primed (DOP) PCR-comparative genomic hybridization (CGH) permits genetic imbalances screening of the entire genome using only small amounts of tumor DNA. In non-metastatic gastric cancers the common sites of copy number increases were detected at 8q (64%), 4p12-q24 (64%), 5p13-q23 (64%), 13q21-q32 (64%), 6q11-q21 (55%), 7q(50%), 14q11.2-q21 (45%), 3q11-q13.3 (41%), and 2q23-q32 (41%). In metastatic gastric cancers, the frequent sites of gains were detected at 8p21-qter (60%), 5 (54%), 20 (42%), 6pter-q24 (51%), 1q21-qter (46%), 3p14-qter (46%), 22q (46%), and 4 (43%). Deletion or chromosomal loss was found to be less frequent in this study. The frequent sites of copy number decreases were detected at 1p34-pter (23%), 16q23-q24 (18%), and 19q13 (18%) in non-metastatic gastric cancers. In metastatic gastric cancers, chromosome losses were detected at X (37%), 1p33-pter (37%), and 16p (23%). The recurrent gains and losses of chromosomal regions identified in this study provide candidate regions that may contain oncogenes or tumor suppressor genes respectively involved in the tumorigenesis of gastric cancer.

Objective: Deficits in social cognition (mentalization) and other cognitive deficits have been reported in patients with major depressive disorder (MDD) and may influence treatment response. This study examined the impact of cognitive function on treatment response of patients with MDD after 8 weeks of medication and whether the impact was mediated by mentalization. Methods: Cognitive function (memory, attention, executive function, processing speed) and mentalization were measured in 28 patients with MDD at baseline using neuropsychological tests and self-report scales. The treatment response was defined as the rate of improvement in symptom severity and global function. Results: Multiple regression analyses, controlling for mentalization and cognitive function, separately revealed that delayed recall was a negative predictor of functional improvement after 8 weeks of treatment, while mentalization was a positive predictor. A single mediation model using PROCESS macro showed that delayed recall and Digit Span backward indirectly affected functional improvement, mediated by mentalization. When age at onset was controlled for as a covariate, the mediating effect lost significance, and the direct effect of delayed recall on functional improvement was still significant. Conclusion Despite the small sample size, our results provide evidence that patients with MDD and low memory (delayed recall) at baseline may benefit more from short-term pharmacological treatments.
