OBJECTIVE: To establish the evaluation system of the quality of oocytes on the basis of the incidence of cumulus cells apoptosis, to investigate the relationships between the incidence of cumulus cells and the outcomes of IVF-ET. METHOD: Thirth-four cycles undergoing controlled ovarian hypersimulation for IVF-ET with tubal infertility (23 cycles) or unexplained infertility (11 cycles) were included in this study. Cumulus cell masses surrounding mature oocyte and co-culture of embryos with autologous cumulus cells during IVF-ET process. The incidence of apoptosis in cumulus cells was assessed by apoptosis detection kit fluorescein. The effect of co-culture using cumulus cells and the incidence of cumulus cells apoptosis. RESULTS: The results were as follows: 1. The incidence of apoptosis in cumulus cells markedly increased in patients aged 40 or over, while the fertilization rate was greatly decreased in those age group. 2. Apoptosis in cumulus cells was found in both the fertilized oocytes and unfertilized oocytes, but the incidence of apoptosis was higher in unfertilized oocytes. 3. There is no clear correlation between apoptosis in cumulus cells and the number of oocytes retrieved. However, the incidence of apoptosis was increased when the number of oocytes retrieved was 5 and fewer in comparison with 6~10. 4. Embryo grade was significantly affected by the incidence of apoptosis in cumulus cells. 5. Pregnancy rate of IVF-ET per cycle was 29.4%, and the pregnant group had the higher fertilization rate and a significantly lower incidence of apoptosis in cumulus cells compared with the nonpregnant group. 6. When cumulus cells were used as helper cells in the co-culture of the embryo, in vitro activity of cumulus cells based on morphological change and proliferation did not influence the quality of embryo, but was closely associated with the implantation rate and pregnancy rate, which was enhanced when morphological changes and proliferation of cumulus cells was more active. 7. This difference in the outcome of IVF-ET according to in vitro activity of cumulus cells used for co-cultue was not associated with the incidence of apoptosis in cumulus cells, but rather had likely relations with the different secretion pattern of protein, which may be an embryotrophic factor by cumulus cells. CONCLUSION: These results suggest that the incidence of apoptosis in cumulus cells can be used in predicting oocyte qualities and the outcomes of IVF-ET. And the effect of co-culture largely depends on the in vitro activity of cumulus cells as well.

Naltrexone is a competitive antagonist of μ, δ, and κ opioid receptors. Naltrexone has been investigated for use an as anti-obesity agent in both the general population and in patients with severe mental illness, including schizophrenia. In patients with schizophrenia, however, potential psychotic symptoms due to adverse effects of naltrexone have not been investigated. Our case study, a relevant case report, and some related articles suggest that naltrexone might be associated with the emergence of visual hallucinations, which clinicians should be aware of.

PURPOSE: To evaluate the treatment outcome and prognostic factor of postoperative radiotherapy for extremity soft tissue sarcoma (STS). MATERIALS AND METHODS: Forty three patients with extremity STS were treated with conservative surgery and postoperative radiotherapy from January 1981 to December 2010 at Korea University Medical Center. Median total 60 Gy (range, 50 to 74.4 Gy) of radiation was delivered and 7 patients were treated with chemotherapy. RESULTS: The median follow-up period was 70 months (range, 5 to 302 months). Twelve patients (27.9%) sustained relapse of their disease. Local recurrence occurred in 3 patients (7.0%) and distant metastases developed in 10 patients (23.3%). The 5-year overall survival (OS) was 69.2% and disease free survival was 67.9%. The 5-year local relapse-free survival was 90.7% and distant relapse-free survival was 73.3%. On univariate analysis, no significant prognostic factors were associated with development of local recurrence. Histologic grade (p = 0.005) and stage (p = 0.02) influenced the development of distant metastases. Histologic grade was unique significant prognostic factor for the OS on univariate and multivariate analysis. Severe acute treatment-related complications, Common Terminology Criteria for Adverse Events (CTCAE) grade 3 or 4, developed in 6 patients (14.0%) and severe late complications in 2 patients (4.7%). CONCLUSION: Conservative surgery with postoperative radiotherapy achieved a satisfactory rate of local control with acceptable complication rate in extremity STS. Most failures were distant metastases that correlate with tumor grade and stage. The majority of local recurrences developed within the field. Selective dose escalation of radiotherapy or development of effective systemic treatment might be considered.

Congenital renal arteriovenous fistula is a rare disease and manifested by gross hematuria, bladder tamponade and flank pain. We experienced one case of congenital renal arteriovenous firstula which was cirsoid type and treated with superselective transcatheter arterial embolization of four small segmental arteries. The microcoils made of platinum and synthetic fiber were used as theembolization modality.

Hepatoma is one of the most common malignant disease among cancers that occur in Korea. Recently, according ta developing imaging diagnostic technology and non surgical treatment the hepatoma is easily detected in early diagnosis and appropriate treatment. From this point of view, the histologic pattern of hepatoma is markedly important. This is the first reported case of sclerosing hepatocellular carcinoma, which is characterized by intense fibrosis, in which the tubular neoplastic structures are embedded. The incidence of sclerosing hepatocellular carcinoma is very rare. Therefore the rare histologic pattern of hepatoma might be introduced by many studies and reports. We recently experienced a case of sclerosing hepatocellular carcinoma.

OBJECTIVES: The purposes of this study were to develop the Korean version of Wahler Physical Symptom Inventory (WPSI), to examine the reliability and validity of it, and to investigate usefulness for diagnosing somatization. METHODS: The normal group was composed of 242 persons consist of middle and high school students, university students, and adults living in Seoul, Puchon, and Suwon. The two clinical groups consisted of 33 persons with somatic symptoms and 38 diabetic patients. RESULTS: Internal consistency (Cronbach alpha=.91) was very high. Test-retest reliability was calculated from 46 university group, and it's correlations was also high (.87). And the total score of K-WPSI was significantly and positively correlated with subscales of SCL-90-R. There was significant difference between the normal, psychiatry group, and diabetic group of K-WPSI (F=15.48, p<.001). Especially, K-WPSI was very useful to differentiate between the somatization group and diabetic group. CONCLUSION: K-WPSI was found to be a reliable and valid instrument for diagnosing somatization, and for differentiating somatization and diabetic groups. K-WPSI is a brief and economical questionnaire, which may curtail medical expenses of patients. It is also expectated that K-WPSI can be used for identifying somatization and providing information which may contribute to ascertain diagnosis. The limitation of this study is the small normative data, and not distinguishing sex differences. This limitation should be supplemented by future studies.

The aortic dissection is an acute aortic syndrome, caused by an intimal tear and subsequent splitting of the media by the pulsatile blood flow. Though there would be differences in the origin of aortic dissection and therapeutic modalities, the intermediate and long-term prognoses are poor. Endovascular Stent-graft implantation is a revolutionary technique in the treatment of aortic dissection. The endovascular stent grafting in aortic dissection is less invasive and feasible method and is an effective tool for closing the entry site and promoting clot formation, reducing the size of the false lumen. Therefore, endovascular Stent-graft implantation makes possible the desirable remodelling of aorta. We report 33 year-old male with aortic dissection in the thoracic aorta, which was treated with endovascular Stent-graft implantation. Over the favorable remodelling, his dissection was healed completely by the endovascular treatment using Stent-graft.
