Systemic lupus erythematosus(SLE) is an autoimmune disease characterized by multisystem involvement including central nervous system and various neurologic symptoms. The authors experienced a case of brain SLE and report MRI and other neuroimaging findings.

Pelvic fistulas may result from obstetric complications, inflammatory bowel disease, pelvic malignancy, pelvic radiation therapy, pelvic surgery, or other traumatic causes, and their symptoms may be distressing. In our experience, various types of pelvic fistulas are identified after pelvic disease or pelvic surgery. Because of its close proximity, the majority of such fistulas occur in the pelvic cavity and include the vesicovaginal, vesicouterine, vesicoenteric, ureterovaginal, ureteroenteric and enterovaginal type. The purpose of this article is to illustrate the spectrum of imaging features of pelvic fistulas.

Avascular necrosis of the femoral head is the most common disease for which total hip arthroplasty is being performed in Korea. In order to develop a femoral stem having a proper fit to Korean femur, it is essential to study the change in the shape of the proximal endosteal canal of the femur resulting from disuse caused by pain avascular necrosis of the femoral head. The size and shape of the proximal femur were measured with 3-dimensional images reconstructed from the CT data of 116 femurs in 58 patients who had suffered from avascular necrosis of the femoral head. Among them, there were 30 patients who had suffered from unilateral involvement of avascular necrosis of the femoral head. The comparative study was made on the shape of the proximal endosteal canal of the femur between the normal and the diseased femurs. The shape of proximal endosteal canal of femur in avascular necrosis didn't show statistically significant difference from that of the normal femur. Therefore, the femoral stem designed from the data of normal femurs can be usually applied to the avascular necrosis without problem in obtaining the maximal fit between the stem and the endosteal canal. The canal flare index was greater and the proportion of champagne-flute type was higher in Korean than in Westerner. The shape of the endosteal canal of isthmus was nearly circular in Korean in contrast to anteroposteriorly ovoid in Westerner. The distribution of sagittal canal flare index which was newly defined in this study was entirely different from that of preexisting canal flare index in coronal plane. It will be necessary to study further in the future.

In this paper, the current status of adolescent suicide prevention and intervention are addressed, including areas related to medicine, counseling, mental health nursing, social welfare, and education. Many preventive efforts and intervention programs have been developed and implemented, but the results have been mostly minimal or unfruitful and many problems arose. First, there is a lack of epidemiological research and developmentally appropriate data on adolescent suicide. Thus evidence-based research on adolescent suicide necessary to make important decisions regarding prevention strategies and the allocation of budgets and human resources is not available. Second, there are only a handful of experts with an appropriate level of education and training. Current suicide prevention efforts are performed as a part of crisis intervention, but only a few persons know how to do so effectively. Finally, a good networking and referral system among each area of service is needed. One of the most important issues might be balancing the levels of service available to each subject and to provide a proper, systematized intervention and continuous crisis management services. In order to create an effective networking and referral system among several service providers for adolescent suicide prevention, we need robust support from the Korean government and local communities.

OBJECTIVES: To evaluate MRI findings of non-recurrent hepatocellular carcinomas with lipiodol uptake (LHCCs) treated with transarterial chemoembolization. METHODS: 28 LHCCs were divided into two groups according to amount of lipiodol uptake and tumor size, retrospectively. According to amount of lipiodol uptake, HCCs were classified into group A with dense lipiodol uptake (more than 90%) and group B with partial lipiodol uptake (between 50% and 90%). For HCC size analysis, group I was defined by a longest diameter of less than 2 cm, and group II was defined by a longest diameter of greater than or equal to 2 cm. RESULTS: In group A (n=16), eight LHCCs showed high signal intensity (SI) on T2-weighted images (T2WI), ten LHCCs showed low SI on T1-weighted imaged (T1WI), six LHCCs showed decreased SI at higher b value of diffusion-weighted images (DWI). In group B (n=12), six LHCCs revealed high SI on T2WI, six LHCCs revealed low SI on T1WI, ten LHCCs decreased SI at higher b value of DWI. As compared with tumor size and SI, six of 12 LHCCs in group I and eight of 16 LHCCs in group II showed high SI on T2WI. Six LHCCs in group I and ten LHCCs in group II showed low SI on T1WI. All LHCCs were not enhanced. CONCLUSION: Signal intensities of LHCCs were variable, but more than half of LHCCs showed high SI on T2WI, low SI on T1WI, decreased SI at higher b value of DWI, regardless of lipiodol uptake or tumor size.

In excimer laser ablation, the methods of epithelial removal include mechanical, chemical(alcohol), and laser ablation. To investigate the effects of the de-epithelialization methods, we removed corneal epithelia of 60 rabbits with above three methods and examined corneal epithelial healing time, stromal PMN cells, and immunohistochemical expression of c-fos with time interval. Corneal epithelia healed in 48 hours in the alcohol and laser ablation groups, but in 72 hours in the mechanical ablation group. The count of the stromal PMN cells was maximal in 12 hours in all three groups, and the inflammaion was prolonged in the alcohol ablation group(p<0.05). The c-fos was expressed after 6 hours, 12 hours and 24 hours in all 3 groups and after 48 hours only in the mechanical ablation group. This study suggests that mechanical ablation may produce a larger damage to cornea than laser and chemical ablations and the expression of c-fos in corneal epithelium may be significant findings related to epithelial wound healing.
