Malignant Mixed Mullerian tumors(MMMTs) are unusual neoplasms occumng mostly in the uterus and, ralely, they arise in the ovary. The clinical features of malignant mixed mullerian tumor of the ovary are similiar to other ovarian malignancies. The clinical course is rapidly progressive and fatal. The optimal treatment modalities has remained elusive. The most reliable prognostic criterion is the initial tumor stage and the overall survival was poor. We experienced two cases of malignant mixed miillerian tumor of the ovary, so we report these cases with a brief review of the concerned literatures.

Purpose: Initial conservative treatment with selective endovascular or surgical intervention has shown successful outcomes in the treatment of spontaneous isolated superior mesenteric artery dissection (SISMAD). However, the benefits of antithrombotic therapy as a part of conservative treatment have not been clarified. This study aimed to investigate the clinical course of SISMAD patients and determine differences in clinical outcomes between the antithrombotic and noantithrombotic groups. Methods: We retrospectively reviewed 79 cases of SISMAD that were treated conservatively from January 2004 to December 2019 at Chonnam National University Hospital. Clinical outcomes, including the length of hospital stay, pain resolution time, image remodeling, and maximal remodeling time, were compared between the antithrombotic and noantithrombotic groups. Results: There were 30 patients in the no-antithrombotic group and 49 patients in the antithrombotic group. There was no significant difference in clinical characteristics between the 2 groups, except for dyslipidemia (P = 0.011). The follow-up period (32.6 months vs. 14.6 months, P = 0.009) and imaging follow-up period (31.6 months vs. 13.9 months, P = 0.011) were longer in the antithrombotic group than in the no-antithrombotic group. The length of hospital stay (5.1 days vs. 7.7 days, P = 0.002) was significantly shorter in the no-antithrombotic group than in the antithrombotic group because patients in the antithrombotic group required longer hospitalization for warfarin titration. Conclusion In patients with SISMAD, conservative treatment without antithrombotic therapy may have clinical benefits such as decreased length of hospital stay compared with conservative treatment with antithrombotic therapy.

OBJECTIVE: To measure gynecologic resources required to care for women who have unscheduled vaginal bleeding while using hormone replacement therapy. MATERIALS AND METHODS: Between January 1996 to December 1998, women presenting with abnormal withdrawal bleeding on HRT were identified and associated clinic visits and gynecologic procedures were recorded during a mean follow-up of 2 years. RESULTS: Among women using cyclic HRT, 28.9% had> OR =1 visit for unscheduled vaginal bleeding 8.7% had> OR =1 endometrial biopsy. Among women using continuous combined HRT, 19.3% had> OR =1 visit for unscheduled vaginal bleeding and 6.4% had> OR =1 endometrial biopsy. The gynecologic procedures used in women using cyclic HRT were 20% of reassurance, 50% of ultrasonograpy, 30% of endometrial biopsy and in women using continuous combined HRT were 50% of reassurance, 16.6% of ultrasonograpy, 33.3% of endometrial biopsy. The results of endometrial biopsy were reported all the benign condition. CONCLUSION(S): Unscheduled vaginal bleeding markedly decreased after 12 months of therapy in women using continuous combined HRT but did not decline among those using cyclic HRT.

PURPOSE: This study demonstrated that apoptosis induced by mycophenolic acid (MPA) is mediated by mitochondrial membrane potential transition (MPT) changes in Jurkat cells. METHODS: Cell viability and MPT changes were measured by flow cytometry. Western blotting was performed to evaluate the expression of Bcl-2 family proteins, Bid, truncated Bid (tBid), cytochrome c, voltage dependent anion channel (VDAC), poly ADP-ribose polymerase (PARP), and protein kinase C-delta (PKC-delta). The catalytic activity of caspase-9 and -3 was also measured. RESULTS: Cell viability was decreased in time- and dose-dependent manners. Bcl-2 protein expression was decreased, but Bax protein expression was identified. A decreased Bcl-XL /Bcl-XS ratio was also noted. The expression of tBid protein also increased in a time-dependent manner in Jurkat cells treated with MPA. While normal MPT appeared as orange fluorescence, abnormal MPT corresponded to green fluorescence. Green fluorescence increased as orange decreased in the MPA-treated cells. Significantly increased concentrations of MPA induced the release of cytosolic cytochrome c. MPA also augmented the catalytic activity of caspase-9 and caspase-3 in Jurkat cells. Our findings demonstrated that MPA-induced apoptosis is mediated by MPT changes accompanied by decreased Bcl-XL expression and the appearance of tBid protein. The release of cytosolic cytochrome c from mitochondria and increased catalytic activity of caspase-9 and caspase-3 were observed in MPA-treated Jurkat cells. CONCLUSION: These results suggest that mitochondrial dysfunction caused by MPA induces human T lymphocyte apoptosis.

The purpose of this paper is to review the colonoscopic fingings of twenty two patients with colonic tuberculosis which were diagnosed by colonoscopic finding, histopathology, and follow-up observation after antituberculosis chemotherapy at Pusan National University Hospital from January 1992 to December 1994. The results were as follows: 1) The male to female ratio was 1: 1.2, and the average age of the patients was 39.4 years with a slight predominance in women. The age of peak incidence was the 4th decade 40.9%). 2) Abdominal pain(95%), diarrhea(63%), and weight loss(50%) were the most common clinical findings. Others were constipation, melena, and palpable abdominal mass. The location of the pain was right lower abdomen, epigastrium, central abdomen, and left lower abdomen in decreasing order. 3) Hematologic findings showed decrease in hemoglobin level, increase in ESR, and positive CRP(61.5%). The white blood cell counts were mostly normal. 4) The stool examination showed positive occult blood in 7 cases among 18 cases (38.9%). Acid-fast bacteria was observed in stool of one case. 5) On colonoscopy, the lesion sites were ileoeecal valve(75%), ascending colon(72.7 %), terminal ileum(52.6%), cecum(42.9%), transverse colon(31.8%), descending colon (27.3%), sigmoid colon(9%), and rectum(9%) in decreasing order of frequency. Most of them involved ileocecal area. 6) On colonoscopy, the shape of ulcer revealed circular(41%), fusion(36%), and irregular pattern(18%). It found skipped area in 9 cases, pseudopolyp in 8 cases, patency of ileocecal valve in 5 cases, and severe deformity of ileocecal valve in 6 cases. 7) Microscopic finding of biopsy specimens revealed noncaseating granulomatous inflammation in 12 cases, and nonspecific ulcerative inflammation in 10 cases. In conclusion the diagnostic yield may be greatly enhanced by obtaining multiple target biopsies frorn tbe deep portion of the ulcer bed and margins. Judged from the colonoscopic finding and clinical improvement after antituberculosis chemotherapy, more accurate diagnosis can be acquired.

PURPOSE: We investigated whether suprarenal and infrarenal aortic angles change after the endovascular aneurysm repair (EVAR) procedure and during follow-up, and investigated the correlation between infrarenal aortic angle after EVAR and type Ia endoleaks. METHODS: Data collected on 70 EVAR procedures for a fusiform infrarenal aortic aneurysm performed between May 2006 and December 2012 were supplemented with a retrospective review of charts and radiographs. RESULTS: The greater the preoperative infrarenal aortic angle, the greater the suprarenal aortic angle (r = 0.72, P < 0.001). The infrarenal aortic angle decreased after the EVAR procedure and continued to decrease slowly thereafter (all P < 0.001). Suprarenal aortic angle decreased immediately after the EVAR procedure and continued to decrease during the first month (P < 0.001). No differences in angulation were observed based on stent graft type. Type Ia endoleaks occurred with significantly greater incidence in patients with a larger post EVAR infrarenal angle (P = 0.037). CONCLUSION: The infrarenal aortic angle decreased significantly immediately after the EVAR procedure and continued to decrease slowly thereafter. Suprarenal aortic angle decreased immediately after the EVAR procedure and continued to decrease during the first month. We found a correlation between infrarenal and suprarenal aortic angle. Type Ia endoleaks occurred with greater incidence in patients with a larger infrarenal angle immediately after EVAR.

The feature of congenitial hand anomalies is multiple and complex. Polydactyly and syndactyly is one of the most common congenital anomalies of the upper limb. The statistical analysis of these anomaly is the basic study of congenital hand anomalies. However, the number of reports is small. The purpose of this study is to compare and analyze objective data and make a nation-wide statistical report on polydactyly and syndactyly. We used data from the National Health Insurance Corporation for reviewing polydactyly and syndactyly. We reviewed 3 years of data from 1998 to 2000 focusing on age, the number of operations, male to female ratio, the duration of hospital care and cost. The number of operations for polydactyly was 694 cases and for syndactyly was 574 cases. Therefore we may assume that polydactyly occurs 1:910 births and syndactyly occurs 1:1101 births. The duration of hospital care for polydactyly was 12 days and for syndactyly was 17 days. The full cost for the correction of polydactyly was 770,000 won and syndactyly was 1,220,000 won. The ratio of polydcatyly and syndactyly was 1.12:1. The operation for polydactyly and syndactyly was performed between the age of 1 and 2 in most cases. Male to female ratio of polydactyly was 1.14 :1 and syndactyly was 1.39:1. This study will be helpful to find appropriate treatment for congenital hand anomalies.

The teratoma is a unique complex neoplasm and is one of the most frequent pediatric tumors originated from the extragonadal germ cells. Mature teratoma is composed of mature differentiated tissues, while immature teratoma always contains embryonic tissues of variable degrees of immaturity, especially in the neuroepithelial elements. Diagnosis of teratoma is relatively easy by conventional radiologic study, but the immaturity can be identified only by histopathological examination. Between January 1993 to December 2002, 63 cases of teratoma were operated and analysed retrospectively at the Chonnam University Hospital Female to male ratio was about 3:1 and age distribution was relatively even. Among 63 cases, gonadal teratoma was the most common (52.4%), followed by sacrococcygeal (25.4%), retroperitoneal (9.5%) and mediastinal teratoma (9.5%). Fifty-six cases were mature teratomas and seven were immature teratomas. Alpha-fetoprotein (AFP) was elevated in 4 of 6 immature cases, but in 2 of 51 mature ones Elevated AFP progressively returned to normal range by 1 month after operation in all. Complete excision of the mass was performed, and major complication was not noticed. In five immature cases, PEB chemotherapy (Cisplatin, Etoposide, Bleomycin) was performed. Two of 2 cases in histological grade II were well tolerated to the aggressive chemotherapy. One of three cases in grade III expired due to severe bone marrow depression, and two of them expired by tumor recurrences. In conclusion, immature teratoma in histological grade III showed high potentiality of recurrence. Therefore, postoperative chemotherapy has to be applied to the high graded immature tumors.

Coil migration is an extremely rare but hazardous complication of aneurysmal coil embolization. Only 1 case report has described coil migration following endovascular exclusion to gastrointestinal (GI) tract. We report the experience of a case of colon penetration caused by embolization coil placed for internal iliac aneurysm. A 66-year-old man visited the Emergency Department for hematochezia that had persisted for 3 months. Stent insertion and coil embolization of left internal iliac artery aneurysm had been performed on the patient 18 months ago. Colonoscopy was performed. It suggested penetration of sigmoid colon by embolization coil and diverticulum. Angiography revealed extravasation of contrast media at left internal iliac artery. Covered stent deployment was done in the left internal iliac artery. One week after the stent insertion, the patient underwent anterior resection, aneurysm resection, and coil removal. The patient recovered without complications. He was discharged at 2 weeks after the operation.
