Background and OBJECTIVE: There has been a few case reports of anaphylaxis due to honeybee in Korea. In order to observe the clinical feature of bee sting anaphylaxis. Moderials and methods: Six patients living in Kyunggi province area were referred under history of anaphylaxis after the bee sting. Atopy was defined by skin prick test result to common inhalant allergen. Serum specific IgE antibody to each bee antigen was detected by radioimmunoassay to identify the causative bee. RESULTS: All six cases were female. Three had atopy and four had combined allergic diseases such as allergic rhinitis, asthma, and urticaria. The etiologic bees consisted of yellow jacket (6 cases), paper wasp (4 cases), yellow hornet (3 cases), white faced hornet (1 case) and honey bee (1 case). Four cases had experienced anaphylaxis after ant bite and they showed positive result on specific IgE to imported fire ant. Specific immunotherapy against causative bee venom was begun using bee venom extracts from Bayer (USA) based upon results of specific IgE anti-body to bee venom. CONCLUSION: The yellow jacket is the most common cause of bee venom anaphylaxis in this area. Further studies will be needed to evaluate possible cross-reactivity between bee and ant venom.

Endometriosis is defined as the presence of endometrial tissue(gland and stroma) outside the uterus. The incidence of scar endometriosis is quite rare, and must differentiate with cellulitis and abscess. We have experienced one case of perineal endometriosis and one case of abdominal wall endometriosis at the site of postoperative wound scar. The possible pathogenesis of endometriosis and treatment were discussed.

Common complications in a patient with IgG subclass deficiency include recurrent respiratory infections and concomitant inflammatory lung disease. The most effective therapy in these patients is the administration of intravenous immunoglobulin. The authors report a case of severe aspirin-sensitive asthma and recurrent pneumonia with combined IgG1, and IgG3 subclass deficiency in a 19-year-old man. The patient was treated with 0.4g/kg at monthly intervals for 6 months, and is still receiving 0.2g/kg every 2 weeks at our clinic. After the replacement of intravenous immunoglobulin, the patient has clinically improved.

One of the most frequent structural chromosomal anomaly is t(8;21)(q22;q22) that occurs in approximately 5-15% of all acute myeloid leukemia (AML). However, t(3;21)(p21;q22) and t(2;11)(q31;p15) translocations are rarely reported in AML. Here, we report a unique case of AML with two translocations, t(3;21;8)(p21;q22;q22) and t(2;11)(q31;p15). Using multiplex reverse transcription polymerase chain reaction, we identified a RUNX1-RUNX1T1 fusion gene. Following a second relapse, the patient did not respond to therapy and died 55 months following the first diagnosis. We believe that this is the first case describing concurrent chromosomal aberrations involving three-way t(3;21;8) and two-way t(2;11) translocations in de novo acute myeloid leukemia.

PURPOSE: To evaluate the impact of postoperative radiotherapy (PORT) on patterns of failure and survivals in uterine carcinosarcoma patients treated with radical surgery. MATERIALS AND METHODS: Between October 1998 and August 2010, 19 patients with stage I-III uterine carcinosarcoma received curative hysterectomy and bilateral salpingo-oophorectomy with or without PORT at Seoul National University Hospital. Their hospital medical records were retrospectively reviewed. PORT and non-PORT groups included 11 and 8 patients, respectively. They were followed for a mean of 22.7 months (range, 7.8 to 126.6 months). RESULTS: At 5 years, the overall survival rates were 51.9% for entire, 61.4% for PORT, and 41.7% for non-PORT groups, respectively. There was no statistical difference between PORT and non-PORT groups with regard to overall survival (p = 0.682). Seven out of 19 (36.8%) patients showed treatment failures, which all happened within 12 months. Although the predominant failures were distant metastasis in PORT group and loco-regional recurrence in non-PORT group, there was no statistically significant difference in loco-regional recurrence-free survival (LRRFS) (p = 0.362) or distant metastasis-free survival (DMFS) (p = 0.548). Lymph node metastasis was found to be a significant prognostic factor in predicting poor LRRFS (p = 0.013) and DMFS (p = 0.021), while the International Federation Gynecology and Obstetrics (FIGO) stage (p = 0.043) was associated with LRRFS. CONCLUSION: Considering that adjuvant radiotherapy after surgical resection was effective to decrease loco-regional recurrence and most treatment failures were distant metastasis, multimodal therapy including surgery, radiotherapy, and chemotherapy might be an optimal treatment for uterine carcinosarcoma patients.

Patient's respiration can have an effect on movement of tumor range and peripheral organs. Therefore, the respiratory signal was acquired by relation between external markers and movement of patient's abdomen during radiational therapy in order to minimize the effect of respiration. Based on this technique, many studies of rational therapy to irradiate at particular part of stable respiratory signals have executed and they have been clinically applied. Nevertheless, the phase-based method is preferred to the amplitude-based method for the rational therapy related to respiration. Because stabilization of the respiratory signal are limited. In this study, a in-house respiratory signal analysis program was developed for the phase reassignment and the analysis of the irregular respiratory signals. Various irregular respiratory patterns was obtained from clinical experimental volunteers. After then, the in-house program analyzed the factors affecting to phase assignment which is directly related to irradiated sector. Subsequently, accuracy of phase assignment was improved with removement of irregular signals by self-developed algorithm. This study is considered to be useful for not only image reconstruction and elevation of irradiating accuracy through phase assignment of RPM system but also analysis of respiratory signals. Moreover, development of 4D CT image is planed with phantom researches or clinical experiments based on this program.

A 43-year-old woman who had had an invasive mole 5 years previously required emergent pulmonary embolectomy under cardiopulmonary bypass. Curative resection was impossible because the tumor invaded the right main pulmonary artery and left lower pulmonary artery. The pathologic diagnosis made by the tumor emboli specimens was choriocarcinoma. The patient received post-operative chemotherapy over a 6-month period and had complete remission. Although rare, choriocarcinoma should be considered in the differential diagnosis of fertile women presented with pulmonary embolism.

BACKGROUND: Complete resection by the surgery has been selected as the treatment of choice in lung cancer patients, but in cases of recurrence after excision or inoperable cases, the importance of anticancer chemotherapy has been emphasized. If one can select a set of the sensitive chemotherapeutic agents before anticancer chemotherapy, it will give more favourable results. Subrenal capsular assay has been recognized as a useful in-vivo chemosensitivity test of thoracic and abdominal tumors and it can be done in a short time for a rapid interpretation of tumor responsiveness to anticancer chemotherapeutic drugs. It has been reported that various kinds of cancer cells can be implantable to the kidney, but so far there is no comparative study of xenogeneic cell implantation on liver, spleen and kidney. The author implanted the human lung cancer cells under the capsule of S.D rat's liver, spleen and kidney respectively and compared the pattern of growth and histology. MATERIAL AND METHOD: After incubation of human lung cancer cell line (SW-900 G IV) in RPMI 1640 (Leibovitz L-15 medium) culture media, 3x3x3 mm size fibrin clots which contain 108 cancer cells were made. Thereafter the fibrin clots were implanted at subcapsule area of liver, spleen and kidney of S.D. female rat. For immune suppression, cyclosporin-A (80 mg/Kg) was injected subcutaneously daily from post-implantation first day to sixth day. The body weight was measured at pre and post implantation periods. The growth pattern and the size of tumor mass were observed and the pathologic examination and serum tumor marker tests were performed. RESULT: Body weight increased in both of control and experimental groups. Serum Cyfra 21-1 was not detected. Serum levels of CEA and NSE revealed no significant change. The SCC-Ag increased significantly in implanted group. The growth rate of human lung cancer cells which was implanted on spleen was higher than on liver or kidney. The surface area, thickness, and volume of tumor mass were predominant at spleen. The success rates of implantation were 80% on kidney, 76.7% on spleen and 43.3% on liver. Pathologic examination of implanted tumors showed characteristic findings according to different organs. Tumors that were implanted on kidney grew in a round shape, small and regular pattern. In the spleen, tumors grew well and microscopic neovascularization and tumor thrombi were also found, but the growth pattern was irregular representing frequent daughter mass. Human lung cancer cells that were implanted in the liver, invaded to the liver parenchyme, and had low success rate of implantation. Microscopically, coagulation necrosis and myxoid fibrous lesion were observed. CONCLUSION: The success rate of implantation was highest in the kidney. And the mass revealed regular growth that could be measured easily. The SCC-Ag was presented earlier than CEA or Cyfra21-1. The Cyfra21-1 was not detected at early time after implantation. The best model for tumor implantation experiment for chemosensitivity test was subrenal capsular analysis than liver and spleen and the useful serum tumor marker in early period of implantation was the SCC-Ag.

The mechanism of apoptosis was first discovered at the end of the 19th century, but it was only recently that its importance was recognized. Not only in a pathologic environment but also in a normal environment, apoptosis has an important role in homeostasis. The number of cells is restricted by apoptosis which is controlled by several SlgBS lll VlVO. In pregnancy, the placenta regulates the maternal-fetal exchange of molecules and functions as a barrier for the protection of the fetus. As the pregnancy proceeds, changes occur in the number and components of placental cells. Observing the placental tissues, apoptosis was found in the syncytiotrophoblasts of early and late pregnancy. In particular, the fact that apoptosis observed in the placenta of late pregnancy supports the hypothesis that pmgrammed cell death is a normal sequence. Pregnancy-induced hypertension is usually accompanied by abnormal placenta and intrauterine growth restriction. In this study, using the TdT-FragEL DNA fragmentation detection kit, the changes in the nucleus by apoptosis in the placental tissues of 23 to 40 gestational weeks in preeclampsia and eclampsia were compared with normal placenta. Apoptosis was observed in the normal term placenta and in pregnancy-induced hypertension patients, regardless of whether vasculopathy was observed in Doppler ultrasound or confirmed by pathology, more apoptoses were observed aside from the number of gestational weeks.

BACKGROUND: We evaluated the performance of the BD MAX StaphSR Assay (SR assay; BD, USA) for direct detection of Staphylococcus aureus and methicillin resistance not only in S. aureus but also in coagulase-negative Staphylococci (CNS) from positive blood cultures. METHODS: From 228 blood culture bottles, 103 S. aureus [45 methicillin-resistant S. aureus (MRSA), 55 methicillin-susceptible S. aureus (MSSA), 3 mixed infections (1 MRSA+Enterococcus faecalis, 1 MSSA+MRCNS, 1 MSSA+MSCNS)], and 125 CNS (102 MRCNS, 23 MSCNS) were identified by Vitek 2. For further analysis, we obtained the cycle threshold (Ct) values from the BD MAX system software to determine an appropriate cutoff value. For discrepancy analysis, conventional mecA/mecC PCR and oxacillin minimum inhibitory concentrations (MICs) were determined. RESULTS: Compared to Vitek 2, the SR assay identified all 103 S. aureus isolates correctly but failed to detect methicillin resistance in three MRSA isolates. All 55 MSSA isolates were correctly identified by the SR assay. In the concordant cases, the highest Ct values for nuc, mecA, and mec right-extremity junction (MREJ) were 25.6, 22, and 22.2, respectively. Therefore, we selected Ct values from 0-27 as a range of positivity, and applying this cutoff, the sensitivity/specificity of the SR assay were 100%/100% for detecting S. aureus, and 97.9%/98.1% and 99.0%/95.8% for detecting methicillin resistance in S. aureus and CNS, respectively. CONCLUSIONS: We propose a Ct cutoff value for nuc/mec assay without considering MREJ because mixed cultures of MSSA and MRCNS were very rare (0.4%) in the positive blood cultures.
