Until recently, the cervical pregnancy have been treated with surgery, usually hy- sterectomy, because of uncontrollable heavy vaginal bleeding. The development of sophisticated ultrasound which allows early diagnosis of cervical pregnancy and methotrexate chemotherapy opened up new therapeutic options in the management of this unusual but potentially life threatening complication of pregnancy which have been always a nightrnare for the gynecologist. We are reporting a case of cervical pregnancy diagnosed in 12 weeks of gestation. The patient was successfully treated with alternative administration of methotrexate (1 mg/kg, intramuscularly) and leucovorin (0.1 mg/kg, intramuscularly) without surgical intervention, in order to preserve both the uterus and fertility. Follow up was done with serum beta hCG and pelvic ultrasonography. Complete resolution of the cervical pregnancy was obtained at 50 days after starting methotrexate treatment. This case gave us the opportunity to review the recent literature on cervical pregnancy.

The authors performed combined trabeculectomy-cataract extraction on eyes of 8 patients with coexisting glaucoma and cataract. Posterior chamber lens implantation was performed in 2 of 9 eyes. The follow-up period ranged from 6 to 12 months. Visual acuity was improved in 8 eyes. The mean intraocular pressure was reduced by approximately 53%, from 28 mmHg preoperatively to 13 mmHg postoperatively. No medications were required in 6 of the 8 eyes, but 2 needed one medication for adequate control of intraocular pressure, postoperatively. No greater incidence of complications were evident with the combined procedure, from that expected with routine cataract extraction or trabeculectomy alone.

BACKGROUND: Melasma is an acquired, symmetrical hypermelanosis that occurs on sun-exposed areas of the skin. It has significant emotional and psychological effects on those affected with the condition. Melasma Quality of Life Scale (MELASQOL) is a specific questionnaire to identify the most impaired areas of melasma patient's life. OBJECTIVE: Our purpose of this study is to investigate the changing of MELASQOL after the treatment of melasma. METHODS: A total of 27 volunteers with melasma were enrolled in this 8-week treatment study. The patients were instructed to apply an arbutin-containing cream,

OBJECTIVES: A common problem with analyzing survey data involves incomplete data with either a nonresponse or missing data. The mail questionnaire survey conducted for collecting lifestyle variables on the members of the Korean Elderly Phamacoepidemiologic Cohort(KEPEC) in 1996 contains some nonresponse or missing data. The proper statistical method was applied to evaluate the missing pattern of a specific KEPEC data, which had no missing data in the independent variable and missing data in the response variable, BMI. METHODS: The number of study subjects was 8,689 elderly people. Initially, the BMI and significant variables that influenced the BMI were categorized. After fitting the log-linear model, the probabilities of the people on each category were estimated. The EM algorithm was implemented using a log-linear model to determine the missing mechanism causing the nonresponse. RESULTS: Age, smoking status, and a preference of spicy hot food were chosen as variables that influenced the BMI. As a result of fitting the nonignorable and ignorable nonresponse log-linear model considering these variables, the difference in the deviance in these two models was 0.0034(df=1). CONCLUSION: There is a lot of risk if an inference regarding the variables and large samples is made without considering the pattern of missing data. On the basis of these results, the missing data occurring in the BMI is the ignorable nonresponse. Therefore, when analyzing the BMI in KEPEC data, the inference can be made about the data without considering the missing data.

Choriocarcinoma is an aggressively growing and widely metastasizing tumor that originates from trophoblastic cells. A primary gastric choriocarcinoma (PGC), however, is very rare. A 76-year-old female patient visited the emergency department of Wonkwang University Hospital with abdominal discomfort and melena. Esophagogastroduodenoscopy revealed a huge ulceroinfiltrative mass lesion with blood clots on the boundary between the greater curvature side and the posterior wall side of the stomach lower body. CT showed a 3-cm exophytic mass lesion with heterogeneous enhancement, an ulcer lesion at the posterior wall side of the stomach lower body, and multiple enlarged lymph nodes at the splenic artery and left gastric artery nodal stations. She underwent a radical subtotal gastrectomy with a D2 lymph node dissection. The final diagnosis was PGC coexisting with adenocarcinoma based on the pathology results. This paper reports a rare case of primary gastric choriocarcinoma coexisting with adenocarcinoma and discusses the characteristics of this neoplasm with reference to the literature.

Synovial sarcoma is a rare renal neoplasm that is not easy to diagnose unless SYT-SSX fusion transcripts are identified. We report here on a case of primary renal synovial sarcoma in a 35-year-old woman. A mass was discovered by accident in the lower part of the right kidney when ultrasonography was performed, and it was removed via radical nephrectomy. Grossly, the tumor was a homogeneously tan-brown soft mass that measured 4.5x3.2x3.0 cm, and it was encircled by a well-defined cystic space. The lesion exhibited hypercellularity of the oval or short spindle cells that were arranged in various solid sheets or intersecting fascicles. Immunohistochemically, the tumor showed diffuse positivity for vimentin, bcl-2 and CD99, and it showed focal positivity for epithelial membrane antigen. The SYT-SSX fusion transcripts were detected by reverse transcription-polymerase chain reaction (RT-PCR). Synovial sarcoma should be considered in the differential diagnosis when a spindle cell neoplasm is encountered in the kidney.

BACKGROUND: Genetic predisposition and environmental aspects may act as triggering factors and influence the disease expression. Dong-gu, which is located on the west of Incheon, has a large harbor and industrial complex. Such environmental aspects of Dong-gu may play a role in AD. OBJECTIVE: We investigated the epidemiologic features of AD in preschool and elementary school children in Dong-gu. METHODS: This study was carried out among 2,760 preschool and elementary school children from June to October. A questionnaire survey is composed of clinical manifestations, genetic and environment factors and lifestyle. Two dermatologists examined the skin conditions of the subjects. The severity of AD was evaluated using the Eczema Area and Severity Index (EASI) score and the factors affecting the severity of the diseases were determined. RESULTS: The questionnaire suggested that there was 19.7% of the preschool childhood and elementary school students in Incheon with AD. But, the prevalence of AD evaluated by the two dermatologists was 13.2%. The average EASI score is 2.88 (+/-4.08). There was a statistical significance in parental past history, especially of atopic dermatitis and moving into a new house within a year after birth (p<0.05). CONCLUSION: These results suggest that there is strong correlation of genetic and environmental factors in the severity of atopic dermatitis in children.

BACKGROUND: Dendritic cell (DC)-based cancer immunotherapy is studied for several years. However, it is mainly derived from autologous PBMC or leukapheresis from patient, which has limitations about yield and ability of DC production according to individual status. In order to solve these problems, inquiries about allogeneic DCs are performed but there are no preclinical trial answers for effect or toxicity of allogeneic DC to use for clinical trial. In this study, we compared the anti-tumor effect of allogeneic and autologous DCs from mouse bone marrow stem cells in mouse metastatic melanoma model. METHODS: B16F10 melanoma cells (5 x 10(4)/mouse) were injected intravenously into the C57BL/6 mouse. Therapeutic DCs were differentiated from autologous (C57BL/6: CDC) or allogeneic (B6C3F1: BDC) bone marrow stem cells with GM-CSF, SCF and IL-4 for 13days and pulsed with B16F10 tumor cell lysate (Blys) for 18hrs. DC intra-peritoneal injections began on the 8th day after the tumor cell injection by twice with one week interval. RESULTS: Anti-tumor response was observed by DC treatment without any toxicity especially in allogeneic DC treated mice (tumor burden score: 2.667+/-0.184, 2.500+/-0.463, 2.000+/-0.286, 1.500+/-0.286, 1.667+/-0.297 for saline, CDC/unpulsed-DC: U-DC, CDC/Blys-DC, BDC/U-DC and BDC/Blys-DC, respectively). IFN-gamma secretion was significantly increased in allogeneic DC group stimulated with B16F10 cell lysate (2,643.3+/-5,89.7, 8,561.5+/-2,204.9. 6,901.2+/-141.1 pg/1 x 10(6) cells for saline, BDC/U-DC and BDC/Blys-DC, respectively) with increased NK cell activity. CONCLUSION: Conclusively, promising data was obtained that allogeneic DC can be used for DC-based cancer immunotherapy.

BACKGROUND: Tumor cell lysate has been considered as a preferential antigen source for the therapeutic dendritic cell pulsing. Our experiences with in vivo study with animal tumor model indicate the tumor cell lysate dependent differential effect of DC therapy. Our previous data show that MC38 lysate pulsed-DC induced stronger ag-specific immunity than CT26 lysate pulsed-DC in vitro. In this study we tried to reveal the mechanism for differential induction of ag-specific immunity of different colon cancer cell lysate pulsed-DCs. METHODS: MC38 and CT26 cell lines were prepared as lysate by freezing-thawing procedure. Tumor cell antigenicity was confirmed by detecting the surface expression of MHC I/II & B7.1/2 molecules. IL-10, IL-12 and TGF-beta in the tumor cell lysate were detected by ELISA and the presence of heat shock proteins were analysed by western blotting. RESULTS: The secretion of IL-10, a immune-inhibitory cytokine was about 470% higher in CT26 lysate than in MC38. Hsp 70 was detected only in the MC38 lysate but not in the CT26. On the other hand, Hsp 60 and 90 expression were not different in two colon cancer cell lysates. CONCLUSION: In two different colon caner cell lysate, immune inhibitory IL-10 (higher in CT26) and Hsp70 (MC38 superiority) were differentially expressed. These data indicate that higher ag- specific immunity induction by MC38 lysate pulsed-DC may due to the expression of hsp70 and lower secretion of IL-10, a immune-inhibitory cytokine than CT26 lysate. The significance of other cytokine and the surface marker expression will be discussed.
