Uterine torsion is defined as the mtation of more than 45 degrees around the long axis of the uterus or a rotation which is severe enough to produce symptoms. Torsion of the human pregnant uterus is a very rare complication. The diagnosis is problematic and is often made during a cesrean section due to inhibited labor. Torsion of the human pregnant uterus can be caused by myoma or other uterine abnormalities, ovarian cysts, adhesions, abnormal fetal presentations, or fetal abnormalities ( though no cause can be found in about 20% of cases ). Uterine torsion produces symptoms of varying severity depending on the degree of rotation, and duration of the pregnancy. High mortality rates for both mother and infant have been reported. We experienced one case of the torsion of term pregnant uterus and report this case with a brief review of the concerned literature.

BACKGROUND: 5-Hydroxytryptamine3 (5-HT3) receptor antagonists have been reported to attenuate spinal anesthesia-induced hemodynamic changes. This study was conducted to determine whether the second generation 5-HT3, antagonist palonosetron attenuates hypotension and bradycardia during spinal anesthesia. METHODS: Sixty adult patients scheduled for lower limb surgery were enrolled in this study. Patients were randomly assigned to receive either normal saline (Control group, N = 30) or palonosetron (0.075 mg, i.v.) (Palonosetron group, N = 30) prior to spinal anesthesia. Hemodynamic variables were recorded during anesthesia. RESULTS: The mean blood pressure (MBP) were 89.2 ± 11.4 mmHg in the control group and 87.6 ± 12.1 mmHg in the palonosetron group at 10 min after intrathecal injection (P = 0.609). The median blocked levels of the control group and the palonosetron group were T10 (interquartile range, 9-10) and T10 (8-10) at 20 min after intrathecal injection (P = 0.939). Requirements for ephedrine, phenylephrine, and atropine were similar (P = 0.652, 0.533 and 0.417, respectively). The incidences of hypotension (40% vs. 41%) and bradycardia (7% vs. 17%) were comparable (P = 0.562, P = 0.198, respectively) between the control and the palonosetron group. There were no significances in the changes of systolic blood pressure, diastolic blood pressure, MBP and heart rate by the group (P = 0.632, 0.287, 0.556, 0.733, respectively). CONCLUSIONS: Intravenous palonosetron (0.075 mg) prior to spinal anesthesia might not attenuate spinal anesthesia-induced hypotension during low level of neuroaxial block for lower limb surgery.

OBJECTIVES: Cohort studies of associations between air pollution and health have used exposure prediction approaches to estimate individual-level concentrations. A common prediction method used in Korean cohort studies is ordinary kriging. In this study, performance of ordinary kriging models for long-term particulate matter less than or equal to 10 mum in diameter (PM10) concentrations in seven major Korean cities was investigated with a focus on spatial prediction ability. METHODS: We obtained hourly PM10 data for 2010 at 226 urban-ambient monitoring sites in South Korea and computed annual average PM10 concentrations at each site. Given the annual averages, we developed ordinary kriging prediction models for each of the seven major cities and for the entire country by using an exponential covariance reference model and a maximum likelihood estimation method. For model evaluation, cross-validation was performed and mean square error and R-squared (R2) statistics were computed. RESULTS: Mean annual average PM10 concentrations in the seven major cities ranged between 45.5 and 66.0 mug/m3 (standard deviation=2.40 and 9.51 mug/m3, respectively). Cross-validated R2 values in Seoul and Busan were 0.31 and 0.23, respectively, whereas the other five cities had R2 values of zero. The national model produced a higher crossvalidated R2 (0.36) than those for the city-specific models. CONCLUSIONS: In general, the ordinary kriging models performed poorly for the seven major cities and the entire country of South Korea, but the model performance was better in the national model. To improve model performance, future studies should examine different prediction approaches that incorporate PM10 source characteristics.

OBJECTIVE: To investigate whether natural killer (NK) cell and autoimmune antibody acts synergistically, by the action of autoantibodies to increase NK cell number and cytotoxicity, to decrease uterine blood flow during early pregnancy in pregnant women with a history of recurrent spontaneous abortion (RSA). METHODS: Seventy-five pregnant women (between 5 and 7 weeks gestation) with a history of unexplained RSA were included in the study group. Forty-one pregnant women without a history of RSA were included as controls. All women with a history of RSA were tested for autoantibodies and number of peripheral blood natural killer (pbNK) cell by flow cytometry. Study populations were stratified into four groups by existence of autoantibody and degree of increase of pbNK cells. The uterine radial artery resistance index (RI) was measured by color-pulsed Doppler transvaginal ultrasound. RESULTS: The mean RI of the autoimmune antibody-positive (AA+) group (0.63+/-0.09) was significantly higher than that of the normal control group (0.53+/-0.10, P=0.001). The mean RI of the AA+/only-NK elevated (eNK) group (0.63+/-0.09) was significantly higher than those of the only-AA+ group (0.55+/-0.07, P=0.019) and the only-eNK group (0.57+/-0.07, P=0.021). CONCLUSION: Concurrent elevation in NK cells and autoimmunity results in decreased uterine blood flow during early pregnancy. However, the majority of cases of RSA remain unexplained and larger scale studies are needed to confirm our conclusion and to develop diagnostic and therapeutic plans for women with a history of RSA.

OBJECTIVES: This study was designed to examine the effect of marital satisfaction and dysfunctional attitudes on depression in married women. METHODS: Forty depressed married female patients and 34 non-depressed married women as normal control group completed three self-report questionnaires, Beck Depression Inventory(BDI) Dysfunctional Attitude Scale(DAS) and Dyadic Adjustment Scale(DYAS) Marital satisfaction and dysfunctional attitudes were compared by student t-test between the two groups. Also, relative importances of each variables to depression were examined with stepwise multiple regression analysis. RESULTS: Depressed patients reported significantly lower level of marital satisfaction and showed higher level of dysfunctional attitudes than normal controls. Dyadic satisfaction, approval need, and perfectionism subfactors were more important in predicting depressive symptomatology than other variables in patients. CONCLUSION: We conclude that marital satisfaction has significant influence on development and maintenance of depression in married women, and in underlying thinking process, dysfunctional attitudes serve as a cognitive vulnerability factor. This conclusion involves the expectation that if dysfunctional attitudes of depressed married women could be changed positively, their marital satisfaction will be increased to higher level and depression will be decreased. Overall, our findings stress that we need to consider the degrees of marital satisfaction and dysfunctional attitudes of depressed maried women, when treating them, in order to individualize treatments and optimize our ability to predict responsiveness to therapy.

Ultrasound (US) elastography is a valuable imaging technique for tissue characterization. Two main types of elastography, strain and shear-wave, are commonly used to image breast tissue. The use of elastography is expected to increase, particularly with the increased use of US for breast screening. Recently, the US elastographic features of breast masses have been incorporated into the 2nd edition of the Breast Imaging Reporting and Data System (BI-RADS) US lexicon as associated findings. This review suggests practical guidelines for breast US elastography in consensus with the Korean Breast Elastography Study Group, which was formed in August 2013 to perform a multicenter prospective study on the use of elastography for US breast screening. This article is focused on the role of elastography in combination with B-mode US for the evaluation of breast masses. Practical tips for adequate data acquisition and the interpretation of elastography results are also presented.

PURPOSE: Various tumor antigens can be loaded onto dendritic cells (DCs) to induce a potent cytotoxic T lymphocyte (CTL) response in DC-based immunotherapy against breast cancer. However, in the clinical setting, obtaining a sufficient number of autologous tumor cells as a source of tumor antigens is a laborious process. We therefore investigated the feasibility of immunotherapy using breast-cancer-specific CTLs generated in vitro by use of alpha-type 1 polarized DCs (alpha DC1s) loaded with ultraviolet B-irradiated cells of the breast cancer cell line MCF-7. MATERIALS AND METHODS: alphaDC1s were induced by loading allogeneic tumor antigen generated from the MCF-7 UVB-irradiated breast cancer cell line. Antigen-pulsed alphaDC1s were evaluated by morphological and functional assays, and the breast-cancer-specific CTL response was analyzed by cytotoxic assay. RESULTS: The alphaDC1s significantly increased the expression of several molecules related to DC maturation without differences according to whether the alphaDC1s were loaded with tumor antigens. The alphaDC1s showed a high production of interleukin-12 both during maturation and after subsequent stimulation with CD40L, which was not significantly affected by loading with tumor antigens. Breast-cancer-specific CTLs against autologous breast cancer cells were successfully induced by alphaDC1s loaded with apoptotic MCF-7 cells. CONCLUSION: Autologous DCs loaded with an allogeneic breast cancer cell line can generate potent breast-cancer-specific CTL responses. This may be a practical method for cellular immunotherapy in patients with breast cancer.

Lung cancer in never-smokers ranks as the seventh most common cause of cancer death worldwide, and the incidence of lung cancer in non-smoking Korean women appears to be steadily increasing. To identify the effect of genetic polymorphisms on lung cancer risk in non-smoking Korean women, we conducted a genome-wide association study of Korean female non-smokers with lung cancer. We analyzed 440,794 genotype data of 285 cases and 1,455 controls, and nineteen SNPs were associated with lung cancer development (P < 0.001). For external validation, nineteen SNPs were replicated in another sample set composed of 293 cases and 495 controls, and only rs10187911 on 2p16.3 was significantly associated with lung cancer development (dominant model, OR of TG or GG, 1.58, P = 0.025). We confirmed this SNP again in another replication set composed of 546 cases and 744 controls (recessive model, OR of GG, 1.32, P = 0.027). OR and P value in combined set were 1.37 and < 0.001 in additive model, 1.51 and < 0.001 in dominant model, and 1.54 and < 0.001 in recessive model. The effect of this SNP was found to be consistent only in adenocarcinoma patients (1.36 and < 0.001 in additive model, 1.49 and < 0.001 in dominant model, and 1.54 and < 0.001 in recessive model). Furthermore, after imputation with HapMap data, we found regional significance near rs10187911, and five SNPs showed P value less than that of rs10187911 (rs12478012, rs4377361, rs13005521, rs12475464, and rs7564130). Therefore, we concluded that a region on chromosome 2 is significantly associated with lung cancer risk in Korean non-smoking women.

This study examined the prevalence of oral microbes in the saliva of oncological patients and healthy subjects. PCR was used to assess the frequency of oral microbes including 3 cariogenic bacteria, 5 periodontopathic bacteria and 4 Candida species in the saliva of 104 oncological patients and 52 healthy subjects. Among these microorganims, Streptococcus mutans, Fusobacterium nucleatum and Candida albicans were most frequently detected in both groups. There were no significant differences in the prevalence of cariogenic bacteria between the patient and healthy groups, whereas significant differences in the frequency of Porphyromonas gingivalis and Tannerella forsythia were observed between the two groups (p < 0.05). The prevalence of all five periodontopathogens was higher in the healthy group than in the patient group. The prevalence of C. albicans in patients was significantly higher than that of healthy group (p < 0.05). In conclusion, there were significant differences in the prevalence of P. gingivalis, T. forsythia and C. albicans between the oncological patient group and healthy group.

During recent years, cases of toxic shock syndrome have been reported with increasing frequency in plastic surgery patients. The majority of reports relate to aesthetic plastic surgical procedures such as rhinoplasty, augmentation mammoplasty, liposuction, and chemical peeling. We report a case of toxic shock syndrome with necrotizing fascitis after liposuction in a 23-year-old woman who had erythema and edema, blister formation and gangrene in the skin. The patient was admitted to the intensive care unit, and treatment was initiated with vigorous fluid resuscitation and intravenous antibiotic therapy. During the next days, the condition of the patient worsened, and pulmonary insufficiency required intubation and mechanical ventilation. Surgical treatment with multiple incision and irrigation was performed on the first, third and eighteenth day. The patient was discharged in good health on the 30th day after admission. Toxic shock syndrome with necrotizing fascitis is a rare disease; therefore, it is important to review its diagnostic and clinical features as only early diagnosis and prompt, radical surgery improves the survival rate.
