OBJECTIVE: We investigated the features of endometrial hyperplasia with concurrent endometrial cancer that had been diagnosed by endometrial sampling. Further, we attempted to identify an accurate differential diagnostic method. METHODS: We retrospectively studied 125 patients who underwent a diagnostic endometrial biopsy or were diagnosed after the surgical treatment of other gynecological lesions, such as leiomyoma or polyps. Patients were diagnosed between January 2005 and December 2013 at Busan Paik Hospital. Clinical and histopathological characteristics were compared in patients who had atypical endometrial hyperplasia with and without concurrent endometrial cancer. RESULTS: The patients were grouped based on the final pathology reports. One hundred seventeen patients were diagnosed with endometrial hyperplasia and eight patients were diagnosed with endometrioid adenocarcinoma arising from atypical hyperplasia. Of the 26 patients who had been diagnosed with atypical endometrial hyperplasia by office-based endometrial biopsy, eight (30.8%) were subsequently diagnosed with endometrial cancer after they had undergone hysterectomy. The patients with endometrial cancer arising from endometrial hyperplasia were younger (39.1 vs. 47.2 years, P=0.0104) and more obese (body mass index 26.1+/-9.6 vs. 23.8+/-2.8 kg/m2, P=0.3560) than the patients with endometrial hyperplasia. The correlation rate between the pathology of the endometrial samples and the final diagnosis of endometrial hyperplasia was 67.3%. CONCLUSION: In patients with atypical endometrial hyperplasia, the detection of endometrial cancer before hysterectomy can decrease the risk of suboptimal treatment. The accuracy of endometrial sampling for the diagnosis of concurrent endometrial carcinoma was much lower than that for atypical endometrial hyperplasia. Therefore, concurrent endometrial carcinoma should be suspected and surgical intervention should be considered in young or obese patients who present with atypical endometrial hyperplasia.

PURPOSE: Allergic diseases have been increased in Korea. The aim of this study was to investigate the changes of sensitization rate to inhalant allergens over 10 years in children with allergic diseases from a tertiary referral hospital. METHODS: Skin prick tests were done in total 2,225 children in 2000, 2005, and 2010. Changes of skin reactivity to 12 major inhalant allergens, including Tree pollen mixture I (Alder, Elm, Hazel, Poplar, Willow), Tree pollen mixture II (Beech, Birch, Oak, Plane tree), Dermatophagoides pteronyssinus, Dermatophagoides farina, Alternaria, cat dander, and dog dander were investigated. RESULTS: The sensitization rates to Tree pollen mixture I and II were increased as 5.0%, 6.8% in 2000, 8.5%, 9.8% in 2005, and 14.8%, 17.3% in 2010, respectively (trend P<0.001, P<0.001, respectively). And the sensitization rates to D. pteronyssinus cat dander and dog dander were changed as 55%, 4.8%, 4.8% in 2000, 62.2%, 11.9%, 28% in 2005, and 63.1%, 12.7%, 16.7% in 2010, respectively. The distribution of sensitized pollens was oak (12.8%), beech (12.4%), pine (10.3%), birch (10%), hazel (9.6%), alder (8%), elder (6.9%), elm (5.4%) in the study of 2010. When allergen/histamine ratio was compared, rates of strong sensitization over 4+ to tree pollen were increased. CONCLUSION: The sensitization rates to inhalant allergens were increased in children with asthma or allergic rhinitis from a tertiary referral hospital in Seoul over last 10 years. Especially, an increase in the degree of skin reactivity was observed in cat dander, dog dander, and tree pollens. The studies to investigate the etiology of this increase and prevention will be needed.

BACKGROUND: In reporting results of case-control studies, odds ratios are useful methods of reporting findings. However, odds ratios are often misinterpreted in the literature and by general readers. METHODS: We searched all original articles which were published in the Korean Journal of Family Medicine from 1980 to May 2011 and identified those that report "odds ratios." Misinterpretation of odds ratios as relative risks has been identified. Estimated risk ratios were calculated when possible and compared with odds ratios. RESULTS: One hundred and twenty-eight articles using odds ratios were identified. Among those, 122 articles were analyzed for the frequency of misinterpretation of odds ratios as relative risks. Twenty-two reports out of these 122 articles misinterpreted odds ratios as relative risks. The percentage of misinterpreting reports decreased over years. Seventy-seven reports were analyzed to compare the estimated risk ratios with odds ratios. In most of these articles, odds ratios were greater than estimated risk ratios, 60% of which had larger than 20% standardized differences. CONCLUSION: In reports published in the Korean Journal of Family Medicine, odds ratios are frequently used. They were misinterpreted in part of the reports, although decreasing trends over years were observed.

Bacillus licheniformis is an aerobic, gram-positive, spore-forming rod bacteria usually found in the environment. Infections with B. licheniformis are rare and usually associated with an immunocompromised state, trauma, and an indwelling catheter. We report a case of bacteremic B. licheniformis spondylitis following vertebroplasty in a patient with lung cancer.

OBJECTIVE: The purpose of this study was to examine in vitro development of early preimplantation mouse embryos in various kind of serum-free conditioned media (SF-VCM) manufactured from DMEM cultured with Vero Cells. METHODS: A total of 846 two-cell mouse embryos were cultured in different kind of SF-VCM. SF-VCMs were divided into SF-VCM-10, -30 and -50 by media volume using DMEM #1 media, and divided into SF-VCM #1, #2 and #3 by controlled concentration of glucose and pyruvate (manufactured by DMEM #1: mixed three volume of DMEM-G (DMEM with glutamine without glucose and pyruvate) and one volume of DMEM-GGP (DMEM with glutamine, glucose, pyruvate), #2: mixed same volume of DMEM-G and DMEM-GGP and #3: mixed one volume of DMEM-G and three volume of DMEM-GGP, respectively). Experimental groups were mainly added 10% SSS, and 20% hFF was added to only Control group co-cultured with Vero cells. Development of embryos was observed every 24 hours. Results between different groups were analyzed using Chi-square test, and considered statistically significant when P-value was less than 0.05. RESULTS: In vitro developmental rate by each cleavage stages of mouse embryos cultured in SF-VCMs with a various volumes were significantly (P<0.05) higher in SF-VCM-30 (morula< or =: 97.2%, Blastocyst (BL)< or =: 97.2%, Hatching BL< or =: 82.2%) than other groups. In the rate of development on in vitro co-culture vs. a various SF-VCMs manufactured by DMEM controlled concentration of glucose and pyruvate, Group I (SF-VCM #1) was higher than other groups in each cleavage stages (morula< or =: 98.1%, Blastocyst (BL)< or =: 97.1%, hatching BL< or =: 81.7%, respectively). Moreover, specially, in the developmental rate into the hatching blastocyst < or = after 96 hours in vitro culture, Group I (81.7%) was significantly higher than control group (67.6%, P<0.05). CONCLUSION: SF-VCM #1 manufactured by volume of 30 mL DMEM #1 media cultured in vitro for 48 hours in 250 mL flask was the most effective on in vitro developmental rate of mouse preimplantation embryos. Therefore, it is expected that SF-VCM #1 has application to human IVF-ET.

OBJECTIVE: To evaluate the effect of uterine weight on short-term outcome of total laparoscopic hysterectomy (TLH) for benign gynecological conditions. METHODS: A retrospective medical records review of 265 cases of patients with TLH was performed. Patients included in this study underwent TLH as benign uterine disorders at Kangnam Sacred Heart Hostpital, Hallym University from January 2008 through June 2009. These patients were stratified into three groups; Group 1 patients with uterus weighing less than 180 g (n=60), Group2 patients with uterus weighing 180 g to 350 g (n=141), Group 3 patients with uterus weighing more than 350 g (n=64). The groups were compared as regard postoperative stay, operative time, estimated blood loss, hemoglobin change, conversion to open surgery, and postoperative complications. RESULTS: There was no significant difference in age, gravidity, body mass index, previous pelvic surgery and past medical history. The overall complication rates were not significantly different. But operative time prolonged as uterine weight increased. CONCLUSION: The TLH can be performed successfully in case of enlarged uterus. Therefore the enlarged uterus is not an absolute contraindication for TLH.

Adenofibromas of the uterine cervix, which are classified as benign tumors of mixed epithelium and mesenchymal cells, are extremely rare. Most common symptom is usually abnormal genital bleeding. It is very difficult to diagnose preoperatively. Recommended method of treatment is total hysterectomy, because it usually recurs. We experienced a case of adenofibroma of the uterine cervix with increased CA125, so report it with a review of the literature.

Food allergies affect about 4% of the Korean population, and buckwheat allergy is one of the most severe food allergies in Korea. The purpose of the present study was to develop a murine model of IgE-mediated buckwheat hypersensitivity induced by intragastric sensitization. Young female C3H/HeJ mice were sensitized and challenged intragastricly with fresh buckwheat flour (1, 5, 25 mg/dose of proteins) mixed in cholera toxin, followed by intragastric challenge. Anaphylactic reactions, antigen-specific antibodies, splenocytes proliferation assays and cytokine productions were evaluated. Oral buckwheat challenges of sensitized mice provoked anaphylactic reactions such as severe scratch, perioral/periorbital swellings, or decreased activity. Reactions were associated with elevated levels of buckwheatspecific IgE antibodies. Splenocytes from buckwheat allergic mice exhibited significantly greater proliferative responses to buckwheat than non-allergic mice. Buckwheat-stimulated IL-4, IL-5, and INF-gamma productions were associated with elevated levels of buckwheat-specific IgE in sensitized mice. In this model, 1 mg and 5 mg dose of sensitization produced almost the same degree of Th2-directed immune response, however, a 25 mg dose showed blunted antibody responses. In conclusion, we developed IgE-mediated buckwheat allergy by intragastric sensitization and challenge, and this model could provide a good tool for future studies.

A 15-year old boy visited Samsung Medical Center complaining that when he ate curry and rice two months ago, he developed immediate palatal itching, generalized urticaria, headache and dyspnea. His chest radiographs were normal. He had no history of allergy, but a methacholine provocation challenge test revealed positive findings (PC20 3.62 mg/mL). Skin prick tests revealed positive findings to asparagus, house dust mites (Dp, Df), flower pollens (aster, chrysanthemum, golden rod), weed pollens (mugwort, ragweed, dandelion, short ragweed) and crude extract of curry powder. Specific IgE to Dp, Df and soy bean were positive (6.52, 31.2 and 1.91 kU/L) and total IgE was 1, 207 kU/L by the Pharmacia UniCAP- FEIA. After receiving parental consent, we performed an oral provocation test to confirm the relationship between his symptoms and curry powder. He ingested a small amount of curry powder with pure water, which was increased every 1 hour. We then measured his PEFR every 10 minutes after each subsequent curry powder ingestion. After he ate 20 gm of curry powder in one time, he exhibited profuse sweating, skin rash and dyspnea. When we treated him with epinephrine and bronchodilator, his symptoms improved. He developed the same symptoms 2 hours later, but these symptoms were brought under control by the same medication.

OBJECTIVE: The purpose of this study was to evaluate the clinical usefulness of CD44v6 in patients with histologically confirmed endometrial cancer. METHODS: Immunohistochemistry was used to determine the expression of CD44v6 in 39 hysterectomy specimens with the diagnosis of endometrial cancer. RESULTS: CD44v6 expression was detected in 8 specimens with no myometrial invasion of endometrial cancer, one specimen with <50% myometrial invasion, and none with >50% myometrial invasion. There was a significant association between CD44v6 expression and no myometrial invasion of endometrial cancer. There was a statistically significant association between CD44v6 expression and lymph node metastasis, lymphovascular involvement. And all cases of CD44v6 expression were FIGO stage I with histological grade 1 or 2. CD44v6 expression was statistically related with estrogen receptor expression. Although statistical significance was not revealed, it was likely that CD44v6 expression was related with progesterone receptor expression with positive predictive value of 6/9 (66.7%). CONCLUSION: Significant relationships between myometrial invasion, lymph node metastasis, lymphovascular involvement, surgical stage and expression of estrogen receptor and CD44v6 expression suggest that CD44v6 expression could be a good prognostic factor. CD44v6 expression may have potential clinical usefulness if this expression is demonstrated in a further study with prehysterectomy sampling specimens containing endometrial cancer.
