    ABSTRACT: The objective of the current study was to evaluate the efficacy and feasibility of fibrin sealant (Tisseel®) in the loop electrosurgical excision procedure (LEEP) for cervical intraepithelial neoplasia (CIN 2 or 3). We designed a single-blind, prospective, randomized study in 40 consecutive women undergoing LEEP for CIN 2 or 3 at our institute. Two milliliters of fibrin sealant (Tisseel) was applied to the uterine cervix of 20 women immediately after LEEP surgery (treatment group). We evaluated abdominal pain, vaginal bleeding, vaginal discharge and impairment in daily living after 1 week using visual analogue scale questionnaires and compared the results with those of 20 women who did not receive fibrin sealant (control group). Among 40 women who returned for a follow-up 1 week after LEEP, 25 women (62.5%) reported at least one moderate to severe postprocedural symptom. The mean duration of moderate to severe vaginal bleeding and impairment in daily living during postoperative week 1 for the treatment group and the control group was 0.3 ± 0.80 versus 1.7 ± 2.36 days (p = 0.015) and 0.9 ± 1.37 versus 3.00 ± 2.62 days (p = 0.060), respectively. Intraoperative application of fibrin sealant (Tisseel) in LEEP can decrease postoperative vaginal bleeding and impairment in daily living. © 2015 S. Karger AG, Basel.

    ABSTRACT: Epignathus is an extremely rare type of congenital teratoma arising in the oral cavity. Although it is a benign tumor, it is associated with high mortality and morbidity rates because of severe airway obstruction and other malformations. We present a case of epignathus affecting one fetus in a twin pregnancy. The tumor was associated with multiple congenital malformations including cleft palate, bifid tongue, bifid uvula, congenital heart defect, and bilateral inguinal hernias. The diagnostic value of three-dimensional ultrasonography and magnetic resonance imaging was explored with respect to antenatal counseling and peripartum management.

    ABSTRACT: To identify the correlation between the pre-gravid maternal obesity and the uterine artery pulsatility index (UtA-PI) at 28-34 weeks' gestation, and to evaluate the predictive value of the UtA-PI for the occurrence of adverse outcomes depending on the maternal obesity. Between January 2010 and December 2011, 229 pregnant women were prospectively observed and analyzed. The UtA-PI during 28-34 weeks' gestation was estimated, with abnormal UtA-PI defined if the value was above the 95th centile for gestational age. The patients were classified, using a cut-off value for body mass index (BMI) of 25kg/m(2), into obese (pre-gravid BMI≥25kg/m(2)) and non-obese (pre-gravid BMI<25kg/m(2)) groups. We analyzed the association between the pre-gravid BMI and occurrence of abnormal UtA-PI and estimated their contributions to adverse outcomes using regression analyses. The occurrence of abnormal UtA-PI in the women with pre-gravid BMI over 25kg/m(2) was significantly higher than those with normal pre-gravid BMI (OR: 2.49; 95% CI: 1.22-5.12). In multivariate analyses, the combination with abnormal UtA-PI and pre-gravid BMI over 25kg/m(2) contributed to the occurrence of preterm delivery (OR: 33.5; 95% CI: 7.63-147.21), gestational diabetes (OR: 3.98; 95% CI: 1.17-13.56) and pregnancy induced hypertension (OR: 12.71; 95% CI: 3.45-46.87), compared to the control group with pre-gravid BMI of 25kg/m(2) and less, and normal UtA-PI. Women with pre-gravid BMI over 25kg/m(2) show increased tendency of abnormal uterine artery pulsatility index during 28-34 weeks, which increases the risk of adverse pregnancy outcomes.

    ABSTRACT: Surgical scars are crucial cosmetic problem, especially when in exposed areas such as the anterior neck following thyroidectomy. To evaluate the impact of post-thyroidectomy scars on quality of life (QoL) of thyroid cancer patients and identify the relationship between scar characteristics and QoL. Patients with post-thyroidectomy scars on the neck were recruited. QoL was measured using the Dermatology Life Quality Index (DLQI). Scar characteristics were graded according to Vancouver scar scale (VSS) score. Ninety-seven patients completed a battery of questions at the time of enrollment. Post-thyroidectomy scars were classified according to morphology as linear flat scars, linear bulging scars, hypertrophic scars or adhesive scars. There were 32 patients (33.0%), 9 patients (9.3%), 41 patients (42.3%) and 15 patients (15.5%), respectively, in each group. The mean total DLQI score was 9.02. Domain 2 (daily activities, 2.87 points), which includes questions about clothing, was the most greatly impacted among patients. The total DLQI scores of patients who have experienced scar-related symptoms were significantly higher than those of patients without symptoms (p<0.05). The VSS scores were 3.09 for linear flat scars, 6.89 for linear bulging scars, 6.29 for hypertrophic scars and 5.60 for adhesive scars. However, the DLQI scores did not significantly differ among scar types or VSS scores. Post-thyroidectomy scars on the neck affect the QoL of thyroid cancer patients regardless of scar type. Therefore, clinicians should pay attention to the psychological effects of scars on patients and take care to minimize post-thyroidectomy scar.

    ABSTRACT: Purpose: Cervical cancer is caused by persistent infection with high-risk types of human papillomavirus (HPV). The aim of this study was to investigate the potential of Raman spectroscopy as a stand-alone analytical tool for clinical diagnosis of HPV infection using human cervical fluids. Method: A drop-coating deposition surface-enhanced Raman scattering (DCD-SERS) method was identified as the most effective method of biochemical analysis in cervical biofluids. Results: Using a 2-µL sample, the proposed DCD-SERS method yielded Raman spectra with high reproducibility, noise-independence, and uniformity. Additionally, the produced spectra were independent of the volume of fluid used and detection zone analyzed within the central and the ring zones. The optical detection of HPV infection in cervical fluids could be detected accurately in the central zone. Different Raman spectra were obtained according to HPV type. In particular, HPV-16 and HPV-18, which are the major risk factors for cervical cancer, showed a distinct spectral difference in cervical fluids, with a similar pattern for high Raman bands at >1,000 cm−1 but a different pattern for low Raman bands at <1,000 cm−1. Therefore, all ranges of HPV-gated DCD-SERS could be used to detect the presence of HPV infection. Conclusions: Raman spectroscopy provides a good alternative method for early clinical diagnosis of HPV infection, and we are hopeful that this proposed method of HPV assessment will be approved for use in obstetrics and gynecology clinics.

    ABSTRACT: Anthrax is caused by the spore-forming bacterium Bacillus anthracis-, which has been used as a weapon for bioterrorism. Although current vaccines are effective, they involve prolonged dose regimens and often cause adverse reactions. High rates of mortality associated with anthrax have made the development of an improved vaccine a top priority. To identify novel vaccine candidates, we applied an immunoproteomics approach. Using sera from convalescent guinea pigs or from human patients with anthrax, we identified 34 immunogenic proteins from the virulent B. anthracis H9401. To evaluate vaccine candidates, six were expressed as recombinant proteins and tested in vivo. Two proteins, rGBAA_0345 (Alkyl hydroperoxide reductase subunit C) and rGBAA_3990 (Malonyl CoA-acyl carrier protein transacylase), have afforded guinea pigs partial protection from a subsequent virulent-spore challenge. Moreover, combined vaccination with rGBAA_0345 and rPA (Protective antigen) exhibited an enhanced ability to protect against anthrax mortality. Finally, we demonstrated that GBAA_0345 localizes to anthrax spores and bacilli. Our results indicate that rGBAA_0345 may be a potential component of a multivalent anthrax vaccine, as it enhances the efficacy of rPA vaccination. This is the first time that sera from patients with anthrax have been used to interrogate the proteome of virulent B. anthracis vegetative cells. This article is protected by copyright.

    ABSTRACT: To investigate the effects of meditation on anxiety, depression, fatigue, and quality of life in women who are receiving radiation therapy for breast cancer. Randomized, non-program controlled, parallel intervention clinical trial. The ASAN Cancer Center located in Seoul, Korea. The subjects of this study included 102 female breast cancer patients who had undergone breast-conserving surgery; these female patients were randomized into equally assigned meditation control groups, with each group consisting of 51 patients. The test group received a total of 12 meditation therapy sessions during their 6-week radiation therapy period, and the control group underwent only a conventional radiation therapy. The tools used to evaluate the effects of meditation were Hospital Anxiety and Depression scale, Revised Piper Fatigue scale, and European Organization for Research and Treatment of Cancer-Quality of Life Core-30. The results were analyzed based on the principles of intention-to-treat analysis, and, as a corollary analysis, per-protocol analysis was conducted. The breast cancer patients who received meditation therapy compared with the non-intervention group saw improvements in reduction of anxiety (p=.032), fatigue (p=.030), and improvement in global quality of life (p=.028). Based on the results of this study, an affirmation can be made that meditation can be used as a non-invasive intervention treatment for improving fatigue, anxiety, quality of life, and emotional faculties of women with breast cancer.

    ABSTRACT: Anthrax is an acute infectious disease caused by Bacillus anthracis. We previously reported that the adjuvant CIA06B, which consists of TLR4 agonist CIA05 and aluminum hydroxide (alum), enhanced the immune response to anthrax protective antigen (PA) in mice. This study was carried out to determine whether CIA06B can enhance long-term immune responses to PA in mice. BALB/c mice were immunized intramuscularly three times at 2-week intervals with recombinant PA alone or PA combined with alum or CIA06B. At 8 and 24 weeks post-immunization, the immunological responses including serum anti-PA IgG antibody titer, toxin-neutralizing antibody titer, splenic cytokine secretion and the frequency of PA-specific memory B cells were assessed. Compared with mice injected with PA alone or PA plus alum, mice injected with PA plus CIA06B had higher titers of serum anti-PA IgG antibodies, and higher frequencies of PA-specific memory B cells and interferon-γ secreting cells. Furthermore, anti-PA antibodies induced by CIA06B were more effective in neutralizing anthrax toxin. These results demonstrated that CIA06B is capable of providing long-term immunity when used as an adjuvant in a PA-based anthrax vaccine.

    ABSTRACT: The aim of this study was to identify the adipocyte-specific gene expression patterns in chorion-derived mesenchymal stem cells during adipogenic differentiation. Chorionic cells were isolated from the third trimester chorions from human placenta at birth and identified morphologically and by fluorescence-activated cell sorting analysis. After inducing adipogenic differentiation for 28 days, cells at days 3, 10, 21 and 28 were analyzed by Oil red O staining and RNA extraction in order to assess the expression levels of adipocyte marker genes, including CCAAT-enhancer binding protein α (C/EBPα), peroxisome proliferator- activated receptor γ (PPARγ), fatty acid binding protein 4 (FABP4) and Glycerol-3-phosphate dehydrogenase (GPD2). Cells not induced for differentiation were compared with the induced cells as a control group. Chorion-derived cells showed the same pattern as fibroblasts, and expressed CD73, CD105, and CD166 antigens, but not CD45, CD34, and HLA-DR antigens. On day 3 after differentiation, cells began to stain positively upon Oil red O staining, and continuously increased in lipid granules for 4 weeks. The expression level of C/EBPα increased 4.6 fold on day 3 after induction, and continued to increase for 4 weeks. PPARγ was expressed at a maximum of 2.9 fold on day 21. FABP4 and GPD2 were significantly expressed at 4.7- and 3.0-fold, respectively, on day 21, compared to controls, and further increased thereafter. Human chorion-derived mesenchymal stem cells exhibited the sequential expression pattern of adipocyte marker genes during differentiation, corresponding to adipogenesis.

    ABSTRACT: Objective: To evaluate the characteristics, clinical features and maternal-perinatal outcomes after atypical eclampsia. Methods: In a retrospective study, we compared demographics, clinical characteristics and outcomes between typical and atypical eclampsia. Results: Of 90 eclamptic patients, 56 had typical eclamptic features and 34 had atypical features. Compared to typical eclampsia, atypical eclampsia had higher gestational age (37.6 ± 3.3 vs. 34.6 ± 4.2 weeks, p = 0.001), a higher incidence of no antenatal risk factors [25 (73.5%) vs. 12 (21.4%), p < 0.001], less antepartum seizures [11 (32.4%) vs. 45 (80.4%), p < 0.001], a lower incidence of prodromal symptoms [20 (58.5%) vs. 49 (87.5%), p = 0.002], and a higher incidence of no lesion in brain imaging [16 (47.1%) vs. 12 (21.4%), p = 0.010). Although atypical eclampsia was associated with a lower odd ratio (OR) in composite perinatal complications (OR = 0.22, 95% CI = 0.08-0.60, p = 0.003), composite maternal complications did not differ between the two groups (OR = 0.52, 95% CI = 0.08-0.60, p =0.191). Conclusions: Maternal outcomes did not differ between the two groups. Therefore, more attention should be focused on atypical eclampsia.

    ABSTRACT: Postoperative neck scarring is a major concern for patients who undergo thyroid surgery; however, the treatments for hypertrophic scars are generally considered by patients to provide unsatisfactory outcomes. Therefore, risk factors should be identified and prevention of these factors is considered to be critical in management. We reviewed the medical records of 96 thyroidectomy patients who were divided into two groups based on scar type: patients with hypertrophic (n = 61) and linear flat scars (n = 35). Multivariable logistic regression model was developed to identify risk factors for developing hypertrophic scar. There was no significant difference between the two groups in terms of age, gender ratio, tumor type, and type of operation. Multivariable analysis showed that hypertrophic scar development was associated with scars located within 1 cm above the sternal notch (odds ratio [OR] = 5.94, p = 0.01), prominent sternocleidomastoid muscles (OR = 12.03, p < 0.01), and a high body mass index (OR = 1.33, p = 0.01). The area under the receiver operating characteristic curve for risk factors was 0.85. Development of hypertrophic scar after thyroidectomy was found to be associated with specific preoperative factors such as incision site near the sternal notch, prominent sternocleidomastoid muscles, and high body mass index.

    ABSTRACT: Bullous pemphigoid (BP) is an autoimmune subepidermal bullous disease associated with autoantibodies against BP180 and BP230. Enzyme-linked immunosorbent assay (ELISA) is a sensitive tool for the detection of immunoglobulin G (IgG) anti-BP180 and anti-BP230 autoantibodies. The aim of this study was to evaluate the usefulness of ELISA for diagnosing and monitoring the disease activity of BP. We evaluated serum IgG levels of anti-BP180 and anti-BP230 autoantibodies in 47 BP patients, 16 epidermolysis bullosa aquisita patients, and 15 healthy volunteers using ELISA. Through retrospective review of the medical records, the clinical characteristics of BP including disease activity, duration, pruritus severity and peripheral blood eosinophil counts were assessed. The sensitivity of BP180 ELISA was 97.9%, BP230 ELISA 72.3%, and a combination of the two was 100%. The specificity of BP180 ELISA was 90.3%, BP230 ELISA 100%, and a combination of the two was 90.3%. BP180 ELISA scores showed strong associations with disease activity, pruritus severity, peripheral blood eosinophil counts, and disease duration, whereas BP230 ELISA scores did not. BP180 and BP230 ELISAs are highly sensitive methods for the diagnosis of BP, and BP180 ELISA, in particular, is a sensitive tool for monitoring the disease activity of BP.

    ABSTRACT: Anthrax is an infectious disease caused by Bacillus anthracis. The currently licensed human anthrax vaccines contain protective antigen (PA) as a major protective component and alum as an adjuvant. In this study, we investigated whether CIA05, a TLR4 agonist, is able to promote the immune response to an anthrax vaccine adjuvanted with alum. BALB/c mice were immunized intraperitoneally three times at 2-week intervals with a recombinant B. anthracis PA alone or in combination with CIA05 in the absence or presence of alum, and immune responses were determined 2 or 3 weeks after the third immunization. The results showed that the combination of CIA05 and alum significantly increased both serum anti-PA IgG antibody and toxin-neutralizing antibody titers, and the adjuvant effects were greater when lower antigen doses were used for immunization. Both CIA05 and alum stimulated PA-specific splenocyte secretion of interleukin (IL)-4, IL-5, and IL-6. A combination of the two yielded synergistic effects on IL-4 secretion, but CIA05 tended to repress IL-5 and IL-6 secretions induced by alum. Co-administration of CIA05 and alum also increased GL7 expression in B220(+)CD24(+) splenic cells, indicating the ability to activate B cells. These data suggest that CIA05, combined with alum, could be used to achieve higher immune responses to PA, leading to the development of an effective anthrax vaccine.

    ABSTRACT: Epidermolysis bullosa acquisita (EBA) is an acquired, autoimmune blistering disorder caused by autoantibody production against type VII collagen. The aim of this study was to examine the clinical types, treatments, and outcomes of 30 patients with EBA. In our cohort, the median age of onset was 44.0 years, with a similar incidence for both genders (46.7% male, 53.3% female). The majority of patients had classic type (36.7%) and bullous pemphigoid (BP)-like type (46.7%) EBA. The remaining patients had mucous membrane pemphigoid-like (6.7%), Brunsting-Perry pemphigoid-like (6.7%), and linear IgA bullous dermatosis-like type (3.3%) EBA. All patients were treated initially with a combination of methylprednisolone, dapsone and colchicine. No significant differences in time to remission were identified between patients with classic vs. BP-like EBA. In a second subset analysis of 19 patients, a group treated with high-dose (> 8 mg) methylprednisolone achieved remission earlier (median time to remission: 3 months) than a group treated with low-dose (≤ 8 mg) methylprednisolone (median time to remission: 12 months), irrespective of clinical type (p = 0.003).

    ABSTRACT: In order to control the H9N2 subtype low pathogenic avian influenza (LPAI), an inactivated vaccine has been used in Korea since 2007. The Korean veterinary authority permitted the use of a single H9N2 LPAI vaccine strain to simplify the evolution of the circulating virus due to the immune pressure caused by the vaccine use. It is therefore important to determine the suitability of the vaccine strain in the final inactivated oil emulsion LPAI vaccine. In this study, we applied molecular rather than biological methods to verify the suitability of the vaccine strain used in commercial vaccines and successfully identified the strain by comparing the nucleotide sequences of the hemagglutinin and neuraminidase genes with that of the permitted Korean LPAI vaccine strain. It is thought that the method used in this study might be successfully applied to other viral genes of the LPAI vaccine strain and perhaps to other veterinary oil emulsion vaccines.

    ABSTRACT: Thromobotic thrombocytopenic purpura-hemolytic uremic syndrome (TTP-HUS), characterized by microangiopathic hemolytic anemia, thrombocytopenia, fever, central nervous system abnormalities, and renal dysfunction, is severe multisystem disorder. TTP-HUS occurs predominantly in the reproductive aged-women, associated with poor prognosis. Although the morbidity and mortality have been significantly decreased by using plasma exchange therapy, refractory TTP-HUS remains a tremendous problem. It is crucial to differentiate other microangiopathic hemolytic anemia disease with a confusing presentation and to perform the immediate plasmapheresis. We have experienced three cases, which were initially diagnosed as HELLP syndrome or immune thrombocytopenic purpura. Despite of aggressive plasmapheresis, two women died. We present these cases with a review of the literature on pregnancy–associated thrombotic microangiopathy, including ADAMTS-13 activity assay as a new diagnostic test.

    ABSTRACT: Objective: This exploratory study was undertaken to analyze the anxiety of parents of prenatally diagnosed fetal congenital disease and satisfaction after the multidisciplinary counseling. Methods: The study included 32 prospective parents of antenatally diagnosed congenital disease fetus who received multidisciplinary counseling at The Catholic Congenital Disease Center (CCDC) for the period from May, 2009 through March, 2010. The Korean version of the Spielberger State-Trait Anxiety Inventory (STAI) was utilized to assess parental anxiety. Categories of satisfaction survey were classified into accessibility, professionalism, empathy, recoverability, satisfaction, and expectation after counseling. Results: The mean time and number of medical professionals for each counseling were 58.0±36.9 min and 3.5±1.1 persons. Most common congenital diseases were cardiovascular (36.1%) and urogenital diseases (25.0%). STAI scores were significantly decreased after than before counseling (43.5±5.9 vs 36.9±6.0, P=0.0007). STAI scores after counseling showed significant decrease in prospective mothers who were nulliparous (P=0.0005), less than 35 years old (P=0.0014), had religion (P=0.0014) and counseled more than 40 minutes (P=0.0027). The mean rate of positive satisfactory response about multidisciplinary counseling was 85.6% in satisfaction survey. Conclusion: This study provides evidence of the positive impact on the prospective parental anxiety of a multidisciplinary counseling in prenatal management of fetal congenital diseases.
