A case of unrecognized foreign body in vagina presenting with chronic lower abdominal pain in 20-year-old patient / 대한산부인과학회지

The foreign bodies in vagina cause intense inflammation. Genital complaints in patients could indicate the presence of a vaginal foreign object. Vaginal bleeding and blood-stained, foul-smelling discharge are considered to be the main clinical manifestations of vaginal foreign bodies, and toilet tissue reported as the most commonly found foreign body. The insertion of foreign bodies into the vagina is not uncommon but presentation as lower abdominal pain in an gynaecological clinic is rare. The causes of insertion are sexual stimulation, sexual abuse, accident of post-surgery and most cases find a solution after vaginal speculum examination. We describe a case of foreign body in the vagina of a patient presenting with chronic lower abdominal pain but undetectable and unrecognized in general examination.

The relationship between serum leptin level and metabolic syndrome in postmenopausal women / 대한산부인과학회지

OBJECTIVE: Menopause status may lead to increases of body fat, abdominal obesity, and the incidence of metabolic syndrome (MS). Leptin is an adipokine that is secreted by adipocytes and plays an important role in regulating energy homeostasis and the reproductive system. This study examined the relationship among obesity, MS, and serum leptin levels in pre- and postmenopausal women. METHODS: We divided 168 women who visited St. Vincent Hospital of the Catholic University of Korea in 2006 and 2007 into premenopausal vs. postmenopausal, obese vs. non-obese groups based on their body mass index (BMI) and the presence of MS. We measured serum follicle-stimulating hormone (FSH) level, serum estradiol level, BMI, the waist-hip ratio (WHR) and visceral fat area (VFA), serum fasting glucose, lipid profile, blood pressure, and serum leptin level. RESULTS: Of 56 premenopausal and 112 postmenopausal women, there were 21 (37.5%) premenopausal and 51 (45.5%) postmenopausal women with MS. In the non-obese premenopausal and postmenopausal women, there were positive correlations between FSH, markers of abdominal obesity such as WHR and VFA, and serum leptin after adjusting for BMI in postmenopausal women. In the MS group, only WHR was correlated with the serum leptin level after adjusting for BMI in all groups. CONCLUSION: Increased serum FSH level and abdominal obesity lead to an increased serum leptin level in postmenopausal women. Further studies are needed to clarify the relationship between leptin and the metabolic syndrome, risk of cardiovascular disease in postmenopausal women.

Evaluation of 110 cases of single-port access laparoscopically assisted vaginal hysterectomy (SPA-LAVH) and comparison with multi-port access / 대한산부인과학회지

OBJECTIVE: To evaluate the safety and feasibility of single-port access laparoscopically assisted vaginal hysterectomy (SPA-LAVH) using conventional laparoscopic instruments compared to multi-port access laparoscopically assisted vaginal hysterectomy (MPA-LAVH). METHODS: We reviewed the medical records of 220 patients with uterine leiomyoma or adenomyosis who underwent 110 SPA-LAVH and 110 MPA-LAVH in Incheon St. Mary's Hospital between April 2007 and November 2009. We performed SPA-LAVH with conventional rigid straight laparoscopic instruments in all cases. We also performed a new vaginal cuff closure method, Kim's Vaginal Vault Suspension Method, named after the operator (Kim, YW) in both SPA-LAVH and MPA-LAVH. RESULTS: There was no significant difference in patients' age, operating time, uterine weight, hemoglobin change, frequency of blood transfusion, and incidence of postoperative fever between the two groups. The patients' mean age was 46.1+/-7.0 years (SPA-LAVH) and 45.5+/-6.3 years (MPA-LAVH). The mean operating time was 87.2+/-21.0 minutes (SPA-LAVH) and 83.3+/-20.3 minutes (MPA-LAVH). The mean uterine weight was 261.4+/-139.7 g (SPA-LAVH) and 257.8+/-132.9 g (MPA-LAVH). The mean hemoglobin change was 1.1+/-0.7 g/dL (SPA-LAVH) and 1.2+/-0.6 g/dL (MPA-LAVH). Neither bowel injury nor urinary tract injury occurred during the operation in the two groups. One of the SPA-LAVH and one of the MPA-LAVH cases were converted to abdominal total hysterectomy. The mean hospital stay time was shorter with SPA-LAVH (2.6+/-0.6 days [SPA-LAVH] and 3.3+/-0.7 days [MPA-LAVH], P<0.05). CONCLUSION: SPA-LAVH using conventional rigid straight laparoscopic instruments can be offered as a safe and feasible alternative to MPA-LAVH.

Relationship between metabolic syndrome and bone mineral density in the postmenopausal women / 대한산부인과학회지

OBJECTIVE: Observational studies suggest that osteoporosis is associated with cardiovascular disease, although another study found that metabolic syndrome (MS) has protective effects on bone. Therefore, this study examined the relationship between metabolic syndrome and bone mineral density (BMD) in postmenopausal women. METHODS: We divided postmenopausal women who visited St. Vincent Hospital of the Catholic University of Korea in 2006 and 2007 into groups with and without MS and measured their body mass index (BMI), waist-hip ratio (WHR), blood pressure, serum fasting glucose, lipid profile, and BMD of the lumbar spine and femoral neck. RESULTS: Of the 151 subjects, 66 (43%) had MS and 85 (57%) did not. The women with MS had a higher BMD at the lumbar spine and femoral neck, although after adjusting for age and BMI, this correlation was lost. Significant positive correlations were observed between BMD of the lumbar spine and both high-density lipoprotein (HDL) cholesterol and serum fasting glucose, and BMD of the femoral neck was positively correlated with serum fasting glucose level. The components of MS were not correlated with BMD in these postmenopausal women after adjusting for age and BMI. CONCLUSION: In our study, the higher BMD in MS was explained by the higher BMI in postmenopausal women. After adjusting for age and BMI, however, MS had no protective effect on bone mass. MS may be another risk factor for postmenopausal osteoporosis.

Multiparametric Flow Cytometry in Breast Cancer Cell Line (MCF-7) Stained with Fluorescein Isothiocyanate, Phycoerythrin, and Propidium Iodide / 대한암학회지

PURPOSE: Multiparametric flow cytometry is a powerful tool for analyzing the phenotypic, cell kinetic and ploidy heterogeneity of tumor cell populations. But there are major problems such as inaccurate results by the contribution of non-neoplastic cell contamination and the substantial spectral overlap of PI (propidium iodide) into PE (phycoery- thrin) fluorescent emissions on a standard flow cytometer. Recent studies suggested that the emission spectral overlap from PI into PE could be sufficiently compensated electrically and the cytokeratin, a marker for epithelial tumor cells, are successfully used in conjunction with DNA specific dye so as to obtain DNA profiles selectively for cytokeratin-positive tumor cells. The aim of this study was to investigate the feasibility that multiparametric analysis in heterogeneous cell populations of cell lines like solid tumors, which were stained triply with PE, fluorescein isothiocyanate FITC, and PI, can be done without any influences by the contaminated normal diploid cell populations and without spectral overlap between fluorochromes on a standard flow cytometer. MATERIALS AND METHODS: MCF-7 cell lines and heterogeneous cell populations mixed with MCF-7 cells and human peripheral blood lymphocytes were fixed with 1% paraformal- dehyde and permeabilized with 100% methanol. Cytokeratin was labeled with PE and some proliferat!on-associated markers were labeled with FITC, which were followed by DNA staining by PI. These triply stained cells were measured on a standard FACScan flow cytometer equipped with 488 nm single laser and those acquired data were analyzed with WinList 3.0 and ModFit LT software programs on personal computor. RESULTS: Coefficient of variation (CV) of GoG1> peak of MCF-7 cells alone was 4.3. GoG1, S, and G2M phase fractions were 44.9%, 45.9%, and 9.2% respectively. FITC, PE and PI fluorochromes could be detected without any interference between them. CVs of GoG1 peak of PBL and MCF-7 cells in those heterogeneous population were 2.3 and 4.2 respectively. The DNA index of MCF-7 cells was 1.7. MCF-7 cells expressed the cyto- keratin, PCNA, p53, c-erbB/2 and c-myc antigen and in contrast, PBL did not express cytokeratin. The cell cycle phase fractions and oncoprotein expressions could be detected separately in diploid PBL and aneuploid MCF-7 cells in the mixed cell population without any influences by each other. CONCLUSION: These results suggested that the cellular antigen expressions of the malignant cells can be analyzed selectively without influences of fluorescent signals from nonneo- plastic cells. The neoplastic tumor subpopulations are clearly identified on the basis of both ploidy status and antigen expressions. The positive cytokeratin expressions indicate that they were derived from the epithelium, providing objective evidence of the tissue of origin and more precise analysis of DNA contents, ploidy, and oncogene expressions selectively with possible correlation between them. Thus, this method offers new possibilities for multiparameter flow cytometric analysis in the heterogeneous solid tumor cell populations.
