    ABSTRACT: A 39-year-old woman with a 9-week abdominal pregnancy noted pain in her lower abdomen and left leg. Since successive thrombi were observed extending from the left common iliac vein to the popliteal vein along with a thrombus in the left pulmonary artery, we diagnosed her with pulmonary thromboembolism with deep venous thrombosis (DVT). May-Thurner syndrome may have contributed to DVT in the left leg when the left iliac vein was compressed by the right iliac artery. She underwent anticoagulant therapy with heparin, followed by the subcutaneous injection of heparin at home after discharge. We herein report the case of a pregnant woman with May-Thurner syndrome who safely gave birth.

    ABSTRACT: Objective: To evaluate whether microfluidic sperm sorters (MFSSs) allow effective recovery of sorted motile sperm without DNA damage compared with the centrifugation and swim-up procedure. Design: Experimental laboratory study. All participants completed questionnaires regarding previous and/or current diseases, surgery, reproductive experiences, lifestyle factors, and date of the preceding ejaculation. Setting: University research laboratory. Patient(s): Male volunteers were recruited without setting conditions. Semen samples from healthy volunteers (n = 37) were collected in sterile containers by masturbation. Intervention(s): Flow cytometric measurement and sperm chromatin structure assay analysis of DNA damage after sperm preparation using MFSS and the centrifugation and swim-up procedure. Main outcome measure(s): Efficacy and efficiency of sperm preparation, correlation between sperm DNA fragmentation index (DFI) and semen parameters, and relationship between basic characteristics and DFI after the centrifugation and swim-up procedure. Result(s): Final sperm concentration and motility were significantly different between the centrifugation and swim-up procedure and MFSS sperm preparations. A significantly lower sperm DNA fragmentation rate was detected with MFSS compared with the centrifugation and swim-up procedure use. No correlation was observed between DFI and smoking or drinking, but significant correlations were observed between DFI and medication use and sexual abstinence duration. Conclusion(s): MFSSs can be used to efficiently and reliably prepare sperm compared with the centrifugation and swim-up procedure. Further research on the clinical use of MFSSs is required to evaluate the safety and usefulness of this device.

    ABSTRACT: Objective: To validate a new parameter of the distance between the external os (EO) and placental edge (PE) to diagnose a low-lying placenta in the third trimester. Materials and methods: The study participants included 94 uncomplicated singleton pregnant women with cephalic presentation. These women were cared for in our hospital in 1998-2011, with a posterior low-lying placenta, which was diagnosed as the distance between the internal os (IO) and a PE of 0-3.0 cm at 34-36 weeks' gestation. Measurements of cervical length (CL) and the distances of IO-PE and EO-PE were performed using transvaginal ultrasonography at least twice at 28-30 weeks, 31-33 weeks, and 34-36 weeks. Changes in CL, and the IO-PE and EO-PE distances were analyzed. Results: CL and the IO-PE and EO-PE distances did not change prior to 31-33 weeks. CL was shortened and the IO-PE distance was increased after 31-33 weeks (p = 0.0001), but the EO-PE distance was unchanged. Conclusion: The EO-PE distance is a promising parameter for diagnosis of low-lying placenta in the third trimester up to 36 weeks' gestation.

    ABSTRACT: This study aimed to evaluate the efficacy of aprepitant, a neurokinin (NK)1 receptor antagonist, on chemotherapy-induced nausea and vomiting (CINV). A randomized, open-labeled, parallel-design study was undertaken in gynecologic-cancer (GC) patients at the Fukuoka University Hospital. Twenty-three patients were divided into without (group A) or with aprepitant (Group B) in the first cycle of paclitaxel and carboplatin (TC) therapy. From the second cycle onwards, all patients used aprepitant. Statistical significance was assessed using McNemar and Chi-square tests. In the first cycle, the prevalence of a complete response, no episodes of nausea or food intake in group B was significantly increased compared to group A. No significant difference in the prevalence of a complete response or food intake situation was found from the second cycle onwards. Combination of aprepitant with standard anti-emetic therapy may contribute to prevention of CINV in TC therapy for GC patients.

    ABSTRACT: Neuroblastoma (NB) is the most common and lethal extracranial solid tumor in children. The present study aimed to verify that the heparin-binding epidermal growth factor-like growth factor (HB-EGF) is a rational target in NB therapy. We examined expression of EGFR ligands in four NB cell lines using 2-dimensional culture (DC) and 3DC conditions. To assess the anti-tumor effect of cross-reacting material 197 (CRM197), which is a specific inhibitor of HB-EGF, on NB cells, we also performed terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) assay to detect apoptotic cells. HB-EGF was predominantly expressed in two out of four NB cell lines under 2DC and 3DC conditions. CRM197 significantly induced apoptosis of NB cells with high HB-EGF expression. HB-EGF plays an important role in neuroblastoma tumorigenesis and CRM197 showed an effective antitumor effect in neuroblastoma cells.

    ABSTRACT: The study was designed to evaluate the safety of combined chemotherapy with pegylated liposomal doxorubicin (PLD) and irinotecan (CPT-11) in patients with recurrent ovarian cancer. Six patients with platinum-resistant and taxane-pretreated ovarian cancer were enrolled in the study based on the traditional 3-plus-3 design. PLD was administered intravenously on day 1 and CPT-11 on days 1 and 8 of each 28-day course. Initial doses were 30 mg/m(2) PLD and 50 mg/m(2) CPT-11. Hematotoxicity was the principal toxicity (1 patient developed grade 3 neutropenia and 2 developed grade 3 leukocytopenia); hand-foot syndrome was not observed. Furthermore, 1 patient achieved complete response, whereas 2 patients achieved partial response. The combined PLD and CPT-11 regimen was well-tolerated indicating its potential clinical benefit for ovarian cancer patients.

    ABSTRACT: Eph receptor tyrosine kinases are considered candidate therapeutic targets in cancer, but they can exert opposing effects on cell growth. In presence of its ligands, Eph receptor EphA2 suppresses signaling by other growth factor receptors, including ErbB, whereas ligand-independent activation of EphA2 augments ErbB signaling. To deploy EphA2-targeting drugs effectively in tumors, the anti-oncogenic ligand-dependent activation state of EphA2 must be discriminated from its oncogenic ligand-independent state. Since the molecular basis for the latter is little understood, we investigated how the activation state of EphA2 can be switched in tumor tissue. We found that ligand-binding domain of EphA2 is cleaved frequently by the membrane metalloproteinase MT1-MMP, a powerful modulator of the pericellular environment in tumor cells. EphA2 immunostaining revealed a significant loss of the N-terminal portion of EphA2 in areas of tumor tissue that expressed MT1-MMP. Moreover, EphA2 phosphorylation patterns that signify ligand-independent activation were observed specifically in these areas of tumor tissue. Mechanistic experiments revealed that processing of EphA2 by MT1-MMP promoted ErbB signaling, anchorage-independent growth, and cell migration. Conversely, expression of a proteolysis-resistant mutant of EphA2 prevented tumorigenesis and metastasis of human tumor xenografts in mice. Overall, our results showed how the proteolytic state of EphA2 in tumors determines its effector function and influences its status as a candidate biomarker for targeted therapy.

    ABSTRACT: We present a case of osteogenesis imperfecta (OI) type 2A in which a natural course in utero was observed from 23 weeks’ gestation to term. At 23 weeks’ gestation, a sonographic examination showed a cloverleaf skull-like head, a narrow thorax, and marked shortening of the long bones with bowing of the femurs and humeri. Follow-up examinations showed that the cloverleaf skull-like head was not evident at 28 weeks’ gestation. Discontinuity of the ribs and femurs was observed at 26 and 30 weeks’ gestation, respectively. This finding suggested bone fractures, which were confirmed by three-dimensional computed tomography at 32 weeks’ gestation. Ultrasonographic findings of bones, including the long bones and calvarium, changed with advancing gestation during the second trimester. Characteristic features of OI type 2A were evident during the late second to early third trimesters. Repeated ultrasonographic examinations together with three-dimensional computed tomography are necessary for the definitive diagnosis of OI type 2A in the second trimester.

    ABSTRACT: Pulmonary embolism (PE) is the leading cause of maternal death in developed countries, and the prevention of venous thromboembolism (VTE) is a pivotal part of current obstetric care. This study evaluated the safety and efficacy of enoxaparin sodium for thromboprophylaxis after cesarean section (C/S), and analyzed the risk factors associated with VTE. One hundred and forty-three women deemed to be at high risk of postoperative deep vein thrombosis (DVT) were enrolled between January 2011 and May 2012 in seven institutions in Japan. Subcutaneous administration of enoxaparin 4000 units/d was initiated 24-36 hours after C/S for 5 days. Adverse events, based on the Common Terminology Criteria for Adverse Events, Version 4, were recorded. The diagnoses of PE and DVT were made on clinical signs. Venous ultrasonography in the lower extremities was performed in 102 patients. The association between VTE and various risk factors was evaluated using univariate analysis. There were 10 (7.0%) Grade 1 adverse events: elevated aspartate aminotransferase or alanine aminotransferase levels in eight patients, chest pain in one patient, and subcutaneous hematoma in one patient. No patients showed clinical signs of PE and/or DVT. Among 102 patients who underwent venous ultrasonography, thrombus was detected in unilateral soleus veins in four (3.9%) patients. A body mass index (BMI) ≥ 25 kg/m(2) before pregnancy was associated with asymptomatic DVT. The current study demonstrates the safety and efficacy of enoxaparin for thromboprophylaxis after C/S. Further studies are required to determine the best method of preventing asymptomatic DVT. Copyright © 2015. Published by Elsevier B.V.

    ABSTRACT: It can be difficult to differentiate diffuse malignant peritoneal mesothelioma (DMPM) from reactive mesothelial hyperplasia (RMH) or peritoneal dissemination of gynecologic malignancies, such as epithelial ovarian cancer (EOC), which cause a large amount of ascites. Detection of the homozygous deletion of p16/CDKN2A (p16) by fluorescence in situ hybridization (FISH) is an effective adjunct in the diagnosis of malignant pleural mesothelioma. The aim of this study was to investigate the ability of the p16 FISH assay to differentiate DMPM from RMH and EOC. p16 FISH was performed in 28 DMPMs (successful in 19), 30 RMHs, and 40 EOC cases. The cutoff values of p16 FISH were more than 10% for homozygous deletion and more than 40% for heterozygous deletion. According to the above criteria, nine (47.4%) of 19 successful DMPM cases were homozygous deletion positive, and three (15.8%) of 19 were heterozygous deletion positive, whereas all RMH cases were negative for the p16 deletion. In all four major histologic subtypes of EOC, neither p16 homozygous nor heterozygous deletions were detected. To differentiate DMPM from RMH or EOC, the sensitivity of the p16 homozygous deletion was 32% (9/28), and the specificity was 100%. Our study suggests that p16 FISH analysis is useful in differentiating DMPM from RMH and EOC when homozygous deletion is detected. Copyright© by the American Society for Clinical Pathology.

    ABSTRACT: Colorectal cancer (CRC) is one of the most frequently occurring cancers with high morbidity and mortality worldwide. Amphiregulin (AREG), a member of the epidermal growth factor family and a rational target for CRC therapy, is essential for the three-dimensional structure of tumor formation. To clone the genes associated with increased AREG expression, we performed a cDNA microarray analysis in two CRC cell lines undergoing two-dimensional (2DC) and three-dimensional culture (3DC). Upregulated (>2.0-fold) and downregulated (<0.5-fold) genes in 3DC compared with 2DC were selected. Pathway analysis using DAVID based on the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway databases revealed a number of genes involved in glycolysis. In CRC cells, glucose elevated the expression of GLUT1 and AREG as well as the activity of the hypoxia-inducible factor 1 (HIF-1) luciferase reporter promoter. The suppression of AREG expression reduced the uptake of glucose and production of lactate. Luciferase assay identified a critical regulatory region for AREG expression between −130 and −180 bp upstream of the start site, which contained a carbohydrate response element (ChoRE). Max-like protein X (MLX) bound to ChoRE and enhanced the expression of AREG. Together these data suggest that AREG plays a pivotal role in the development of CRC through activation of the Warburg effect.

    ABSTRACT: Ovarian clear cell carcinoma (OCCC) is a worst histological subtype than other ovarian malignant tumor. Heparin-binding epidermal growth factor-like growth factor (HB-EGF) is a promising target for ovarian cancer therapy. The aims of this study were to validate the efficacy of HB-EGF–targeted therapy for OCCC and to identify the transcription factor that contributed to the induction of HB-EGF by SN38 treatment in OCCC cells. HB-EGF was highly expressed in OCCC cells, and an increase of HB-EGF was induced by SN38 which had only antitumor effect among conventional anticancer agents on OCCC. A specific inhibitor of HB-EGF, a cross-reacting material 197 (CRM197), led to a synergistic increase in the number of apoptotic OCCC cells with the treatment of SN38. The luciferase assay with 5′-deletion promoter constructs identified a GC-rich element between −125 and −178 (the distal transcription start site was denoted +1) as a cis-regulatory region, and the treatment of SN38 induced luciferase activity in this region. An in silico and chromatin immunoprecipitation analysis estimated that SP1 bound to the cis-regulatory region of HB-EGF in OCCC cells. Real-time PCR and cell viability assays showed that the transfection of a small interfering RNA targeting SP1 suppressed the expression of HB-EGF induced by SN38, resulting in the enhanced sensitivity of SN38. Taken together, these results indicate that induction of HB-EGF expression contributed to defense mechanism against treatment of SN38 through the transcriptional activity of SP1 in OCCC cells.

    ABSTRACT: Although DNA methylation is considered to play an important role during myogenic differentiation, chronological alterations in DNA methylation and gene expression patterns in this process have been poorly understood. Using the Infinium HumanMethylation450 BeadChip array, we obtained a chronological profile of the genome-wide DNA methylation status in a human myoblast differentiation model, where myoblasts were cultured in low-serum medium to stimulate myogenic differentiation. As the differentiation of the myoblasts proceeded, their global DNA methylation level increased and their methylation patterns became more distinct from those of mesenchymal stem cells and skeletal muscle tissues. Gene ontology analysis revealed that genes whose promoter region was hypermethylated upon myoblast differentiation were highly significantly enriched with muscle-related terms such as "muscle contraction" and "muscle system process." Sequence motif analysis identified 8-bp motifs somewhat similar to the binding motifs of ID4 and ZNF238 to be most significantly enriched in hypermethylated promoter regions. ID4 and ZNF238 have been shown to be critical transcriptional regulators of muscle-related genes during myogenic differentiation. An integrated analysis of DNA methylation and gene expression profiles revealed that de novo DNA methylation of non-CpG island (CGI) promoters was more often associated with transcriptional down-regulation than that of CGI promoters. These results strongly suggest the existence of an epigenetic mechanism in which DNA methylation modulates the functions of key transcriptional factors to coordinately regulate muscle-related genes during myogenic differentiation.

    ABSTRACT: Objective This retrospective study aimed to determine the predictive factors for the efficacy of pelvic arterial embolization for postpartum hemorrhage. Materials and methods Twenty-one patients who underwent pelvic arterial embolization for postpartum hemorrhage of >1000 mL between September 2006 and September 2011 were enrolled in this study. The patients were divided into two subgroups according to the blood loss and time from the end of pelvic arterial embolization to complete hemostasis: good-response (16 patients) and poor-response groups (5 patients). The following predictive factors were compared between the groups: (1) patient characteristics; (2) blood loss; (3) time between delivery (or onset of bleeding) and pelvic arterial embolization; (4) obstetrical disseminated intravascular coagulation score comprising clinical background, clinical signs, and laboratory data; (5) individual disseminated intravascular coagulation score; (6) shock index; and (7) laboratory data including platelet count, prothrombin time-international normalized ratio, fibrinogen, fibrin degradation products, and antithrombin-III at the time of pelvic arterial embolization. Results In the poor-response group, the obstetrical and individual disseminated intravascular coagulation scores and prothrombin time-international normalized ratio were higher than those in the good-response group (p < 0.05). Platelet count, fibrinogen, and fibrin degradation products were lower than those in the good-response group (p < 0.05). All obstetrical disseminated intravascular coagulation scores in the poor-response group were >9 points. Conclusion The efficacy of pelvic arterial embolization is related to the presence or absence of coagulation disorders. When the obstetrical disseminated intravascular coagulation score is high (>9 points), the efficacy may be poor.

    ABSTRACT: Introduction We report the first case of the successful detection of postpartum unruptured vaginal pseudoaneurysm using power- and pulsed-Doppler ultrasonography after delivery. Case description A 38-year-old primiparous Japanese woman had a vaginal laceration with pulsatile bleeding after delivering by vacuum extraction. Transvaginal ultrasonography of the repaired vaginal wall showed an 18 × 20 mm hematoma within which a 6 × 7 mm pulsating anechoic mass was detected. Power-Doppler ultrasonography showed blood flow signals in the anechoic mass. Arterial waveforms detected in pulsed-Doppler mode were suggestive of unruptured pseudoaneurysm. Careful monitoring with contrast-enhanced computed tomography showed an increase in the size of the pseudoaneurysm on the fourth postpartum day. On the sixth postpartum day, massive vaginal bleeding occurred. Emergency angiography revealed strong staining with extravasation from the left vaginal artery, confirming the diagnosis of pseudoaneurysm. Embolization for hemostasis was successfully performed. Discussion and evaluation As far as we know, our case is the first in which an unruptured vaginal pseudoaneurysm was diagnosed using ultrasonography. The differential diagnoses of pseudoaneurysm are arteriovenous malformations including arteriovenous fistula. This case had the typical ultrasonographic patterns of pseudoaneurysm in which the presence of one or two cystic masses in B-mode and color- and/or power-Doppler flow signals was demonstrated along with high-resistance arterial flow waveforms in pulsed-Doppler mode. Sequential examinations of contrast-enhanced CT showed ongoing development of the pseudoaneurysm. In retrospect, we could have performed angiography for embolization when the unruptured pseudoaneurysm was diagnosed, or at the latest when ongoing development of the pseudo-aneurysm was recognized, irrespective of whether symptoms were present. Conclusions Ultrasonography is a non-invasive and clinically useful modality in the differential diagnosis of pseudoaneurysm. Contrast-enhanced computed tomography with or without ultrasonography can be useful for sequential monitoring of the size of unruptured pseudoaneurysms.

    ABSTRACT: Background/aim: Heparin-binding epidermal growth factor-like growth factor (HB-EGF), a member of the epidermal growth factor family, is a target for ovarian cancer therapy. The present study investigated the administration schedule of BK-UM, an anticancer agent targeting HB-EGF. Materials and methods: The ovarian cancer cell line, RMG-I, was injected subcutaneously into five-week-old female nude mice. The BK-UM was administered intraperitoneally, using three administration schedules with different doses. The tumor volume was calculated every week. Statistical significance was assessed using the Mann-Whitney U-test. Results: At doses >0.1 mg/kg, BK-UM displayed significant antitumor effects, although the antitumor effects and body weights of mice did not significantly differ by dose or by three different administration schedules. At a dose <0.1 mg/kg, however, BK-UM had little inhibitory effect on tumor growth. Conclusion: Daily administration of BK-UM, which has a potentially dose-dependent antitumor effect, may be the optimal schedule for clinical application.

    ABSTRACT: The patient was a 76-year-old female with a chief complaint of sudden abdominal pain. She was subsequently transferred to another hospital due to acute abdomen. She was suspected to have superior mesenteric artery embolism based on the findings of enhanced abdominal computed tomography (CT). Reexamination of the CT scans showed ascites and enlargement of the uterus with wall thickening. The patient was transferred to our center due to suspected perforative pyometra. Under a diagnosis of perforative pyometra, abdominal total hysterectomy was performed, which revealed an intrauterine device (IUD) in the uterine according to the pathological findings. The IUD was believed to have caused the patient’s perforative pyometra. Her general condition improved, and she was moved to the Gynecology Department on day 9 after the surgery. Differentiating perforative pyometra from lower intestinal perforation is sometimes difficult. Focusing on the observed low-density area which was associated with the gas image in the uterine cavity based on the findings of a CT scan, it is therefore important to make an accurate and definitive diagnosis preoperatively in the case of this disease. Furthermore, it should be carefully taken into consideration that an IUD can cause a perforated pyometra.

    ABSTRACT: Recently developed transcription activator-like effector nuclease (TALEN) technology has enabled the creation of knockout mice, even for genes on the Y chromosome. In this study, we generated a knockout mouse for Sry, a sex-determining gene on the Y chromosome, using microinjection of TALEN RNA into pronuclear stage oocytes. As expected, the knockout mouse had female external and internal genitalia, a female level of blood testosterone and a female sexually dimorphic nucleus in the brain. The knockout mouse exhibited an estrous cycle and performed copulatory behavior as females, although it was infertile or had reduced fertility. A histological analysis showed that the ovary of the knockout mouse displayed a reduced number of oocytes and luteinized unruptured follicles, implying that a reduced number of ovulated oocytes is a possible reason for infertility and/or reduced fertility in the KO mouse.

    ABSTRACT: The majority of human tumors display a high rate of glycolysis under aerobic conditions. This phenomenon was recognized approximately seven decades ago and is known as the Warburg effect. Several key enzymes required to maintain this high level of glucose metabolism are found in tumor cells. The effects of the glycolytic enzymes are known to be directly or indirectly regulated by various signaling pathways, oncogenes, suppressor genes and transcription factors. Recent molecular biology studies have shown that multiple genetic alterations are related to tumor development. Therefore, these factors may be rational targets for cancer therapy. In this short review, we describe several important molecules that affect aerobic glycolysis and discuss their possible use as therapeutic targets for cancer.

    ABSTRACT: We report anesthetic management of a 38-year-old woman with pulmonary thromboembolism for total hysterectomy. She had been taking oral contraceptives for adenomyosis of the uterus. She had thrombi in the arteries from pulmonary trunk to bilateral main pulmonary arteries. Thrombolytic and anticoagulant therapies did not decrease the thrombi. Removal of the swollen uterus suspected to be the origin of the thrombi, rather than thromboembolectomy, was scheduled. Cannulation for percutaneous cardiopulmonary support was set up just in case of hemodynamic derangement, before the surgery. Cardiac contraction was evaluated with transesophageal echocardiography during the surgery. There was no untoward perioperative event. Pulmonary thromboembolectomy was not done because the postoperative CT revealed shrinkage of the pulmonary thrombi after anticoagulation treatment.
