RESUMEN

BACKGROUND: This study aimed to compare surgical outcomes between two new robotic single-site myomectomy (RSSM)-complementary techniques: coaxial robotic single-site myomectomy (Coaxial-RSSM) and hybrid robotic single-site myomectomy (Hybrid-RSSM). METHODS: Medical records for 132 women undergoing Coaxial-RSSM and 150 undergoing Hybrid-RSSM, consecutively, were retrospectively reviewed. Patient characteristics and surgical outcomes were assessed and compared after propensity score matching (PSM). RESULTS: In the outcomes of PSM, the Coaxial-RSSM group showed significantly reduced blood loss (79.71 vs. 163.75 mL, p < 0.001) and reduced hospital duration (4.18 ± 0.62 vs. 4.63 ± 0.90) relative to the Hybrid-RSSM group. Conversely, Hybrid-RSSM allowed for a shorter operative time compared with Coaxial-RSSM (119.19 vs. 156.01 min, p = 0.007). No conversions to conventional laparoscopy or laparotomy or any need for the multi-site robotic approach occurred in either group. Postoperative complications, including ileus, fever, and wound dehiscence, showed no statistically significant differences between the two groups. CONCLUSIONS: Blood loss was lower with Coaxial-RSSM, and operative time was shorter for Hybrid-RSSM. A follow-up prospective study is warranted for more comprehensive comparison of surgical outcomes between the two techniques.

RESUMEN

Vaginal dysbiosis, such as bacterial vaginosis (BV) and aerobic vaginitis (AV), is an important cause of premature birth in pregnant women. However, there is very little research on vaginal microbial distribution in AV compared to that in BV. This study aimed to analyze the composition of the vaginal microbiota of pregnant women with AV using microbial community analysis and identify the causative organism using each criterion of the AV scoring system. Also, we compared the quantification of aerobic bacteria using quantitative polymerase chain reaction (qPCR) and their relative abundances (RA) using metagenomics. This prospective case-control study included 228 pregnant Korean women from our previous study. A wet mount test was conducted on 159 women to diagnose AV using the AV scoring system. Vaginal samples were analyzed using metagenomics, Gram staining for Nugent score determination, conventional culture, and qPCR for Staphylococcus spp., Streptococcus spp., and Enterobacteriaceae. The relative abundances (RAs) of eleven species showed significant differences among the three groups (Normal flora (NF), mild AV, and moderate AV). Three species including Lactobacillus crispatus were significantly lower in the AV groups than in the NF group, while eight species were higher in the AV groups, particularly moderate AV. The decrease in the RA of L. crispatus was common in three criteria of the AV scoring system (Lactobacillary, WBC, and background flora grades), while it did not show a significant difference among the three grade groups of the toxic leukocyte criterion. Also, the RAs of anaerobes, such as Gardnerella and Megasphaera, were higher in the AV groups, particularly moderate AV, while the RAs of aerobes were very low (RA < 0.01). Therefore, qPCR was performed for aerobes (Staphylococcus spp., Streptococcus spp., and Enterobacteriaceae); however, their quantification did not show a higher level in the AV groups when compared to that in the NF group. Therefore, AV might be affected by the RA of Lactobacillus spp. and the main anaerobes, such as Gardnerella spp. Activation of leukocytes under specific conditions might convert them to toxic leukocytes, despite high levels of L. crispatus. Thus, the pathogenesis of AV can be evaluated under such conditions.

RESUMEN

CGK012 is a newly synthesized pyranocoumarin substance suppressing the activation and transcription of ß-catenin related to Wnt3a-CM. A bioanalytical method for CGK012 was developed and validated in rat plasma, and the method was applied to determine the plasma concentrations after intravenous administration. Plasma was cleaned-up by protein precipitation by acetonitrile including an internal standard. The substances were separated on a reversed-phase column, and the mobile phase was a mixture of water and acetonitrile (3:7, v/v; 0.1 % formic acid). The mass transition occurred at m/z 358.2→229.2 for CGK012 [M+H]+. CGK012 was stable in the various conditions, and the present assay met the criteria of bioanalytical method validation. CGK012 bi-exponentially decayed with the half-life of 4.0 h at the terminal phase. Mean Vd and clearance were 0.69 L/kg and 1.31 L/h/kg, respectively. This is the first bioanalytical method developed for quantification of CGK012 in rat plasma using LC-MS/MS, which would be useful to examine pharmacokinetic study of the substance.

RESUMEN

Ovarian vein thrombosis (OVT) is a rare disease with complications that can be life-threatening. An ovarian vein thrombus in a gestational trophoblastic neoplasia (GTN) is an extremely rare condition that has not been previously reported in the literature. We report the case of a 23-year-old woman who presented with symptoms of amenorrhea for 15 weeks and 6 days along with intermittent lower abdominal pain. She was diagnosed with a hydatidiform mole, and a metastatic workup was scheduled. Abdominal computed tomography showed a right ovarian vein thrombus. She received methotrexate chemotherapy combined with oral anticoagulants. Complete radiological remission was obtained. During the 12-month follow-up period, no disease progression or recurrence was noted. Early recognition and detection of the condition are of the utmost importance. The differential diagnosis of OVT must be considered when there is unexplained abdominal pain, fever, and leukocytosis during the diagnosis and treatment of GTN. A high level of suspicion is required for prompt diagnosis of OVT.

RESUMEN

A supernumerary ovary is a rare gynecological anomaly, and is usually excised due to its malignant transformation potential. We report a case of a supernumerary ovary and endometriosis situated on the anterior rectosigmoid colon. When laparoscopy was conducted, a firm, 5-cm mass was discovered on the anterior rectosigmoid colon along with normal ovaries. In this case, the discovery of a supernumerary ovary implied the presence of endometriosis. It is unusual for endometriosis and a supernumerary ovary to exist simultaneously.

RESUMEN

Mesupron, the first-in-class inhibitor of urokinase-type plasminogen activator (uPA) is known to regulate cell proliferation and migration, and is under investigation for the treatment of metastatic breast cancer. In this study, a quantification method was developed for the determination of mesupron in rat plasma using liquid chromatography with a tandem mass spectrometry (LC-MS/MS). After protein precipitation with acetonitrile including itraconazole (internal standard, IS), the analytes were chromatographed on a reversed phased column with a mobile phase of acetonitrile and water (7:3, v/v, including 0.1% formic acid). The ion transitions of the precursor to the product ion were principally protonated ion [M+H]+ at m/z 630.4→398.3 for mesupron and 705.2→392.1 for the IS. The accuracy and precision of the assay were in accordance with FDA regulations for the validation of bioanalytical methods This method was successfully applied to a pharmacokinetic study of mesupron after intravenous administration in rats.

RESUMEN

OBJECTIVE: Abnormal spiral artery remodeling during early pregnancy leads to preeclampsia. The proliferation and invasion of trophoblasts in pregnancy are important for spiral artery remodeling. This study examined whether heme oxygenase (HO) by-products (carbon monoxide biliverdin, and iron) play roles in regulating the restoration of proliferation and invasion of human umbilical vein endothelial cells (HUVECs), HTR-8/SV-neo cells originating from first-trimester trophoblasts, 3A(tPA 30-1) obtained from term trophoblasts, and human endometrial stromal cells (HESCs) inhibited by zinc protoporphyrin IX (Znpp-9). STUDY DESIGN: We explored whether HO by-products restored the proliferation and invasion of HUVECs, HTR-8/SVneo cells, 3A(tPA 30-1) cells, and HESCs inhibited by Znpp-9 depending on the oxygen concentration. RESULTS: Bilirubin promoted proliferation of HUVECs, HTR-8/SVneo cells, 3A(tPA-30-1) cells, and HESCs under both hypoxic and normoxic conditions. Biliverdin also promoted invasion of HUVECs, HTR-8/SVneo cells, 3A(tPA30-1) cells, and HESCs under both hypoxic and normoxic conditions. Carbon monoxide-releasing molecule 2 promoted the proliferation and invasion of specific cell types depending on the oxygen concentration. CONCLUSION: Our data suggest that HO by-products differentially stimulate the proliferation and invasion of cells involved in pregnancy maintenance. When HO by-products are considered to be stimulants during the invasion and proliferation of such cells, both target cells and the gestational period should be considered.
