    Government transparency and expenditure in the rent-seeking industry: the case of Japan for 1998-2004

    Get PDF
    Since the end of the 1990s, local governments in Japan have enacted Information Disclosure Ordinances, which require the disclosure of official government information. This paper uses Japanese prefecture-level data for the period 1998?2004 to examine how this enactment affected the rate of government construction expenditure. The Dynamic Panel model is used to control for unobserved prefecture-specific effects and endogenous bias. The major finding is that disclosure of government information reduces the rate of government construction expenditure. This implies that information disclosure reduces losses from rent-seeking activity, which is consistent with public choice theory.Information disclosure; Special interest group; Construction expenditure; Rent seeking

    Background and Purpose: Retinal vasculopathy is commonly found with complaintof burred vision by ophthalmologist and closely related to asymptomaticcerebrovascular disease. The purpose of this study was to evaluate patients withmicrovascular retinopathy by ultrasound sonography of neck carotid artery and to findhigh risk group for stroke at outpatient of ophthalmology with associated retinopathy.Methods: Between 1999 and 2001, a total of 480 consecutive patients visited atoutpatient of ophthalmology with a complaint of burred vision were evaluated byultrasound sonography of neck carotid artery. The patients were divided to withretinopathy (n=253) and without retinopathy (n=227). The former was subgrouped asfollows; central retinal vein occlusion (CRVO; n=11), branch of retinal vein occlusion(BRVO; n=71), retinal artery occlusion (RAO; n=8), hypertensive retinopathy group-I(according to Keith, Wagener and Barker's criteria) (HTN-R I; n=43) and group-II(HTN-R II; n=42), and diabetic retinopathy (DM-R; n=78). The latter group was withvarious ophthalmological diseases, mainly inflammation of cornea, with healthy retinalvessels and constituted as the control group.Results: There was no statistically significant difference between patients withretinopathy and the control group with respect to sex distribution, nor among theretinopathy groups. Patients with retinopathy had a mean age of 68 years, while thosewith HTN-R I and II were older with a mean age of 71 years. By ultrasonography,RAO showed pathology in intima-media thickness (IMT; 1.13 ± 0.55 vs. 0.81 ± 0.26 mmin control), average number of plaques (1.88 ± 0.99), degree of stenosis of internalcarotid artery (42.4 ± 28.5 %) and common carotid artery (27.4 ± 21.3 %). Those withDM-R had the second thickest IMT (0.96 ± 0.42 mm) and the second highest quantity ofplaque (1.23 ±1.23), and the second most stenotic common carotid artery (13.1 ±17.28%).Conclusion: Moderate sclerotic changes are found in ophthalmology patients withRAO and DM-R, although the degree pathology do not indicate medical nor surgicalprophylactic treatment. Retinal vein occlusion, that has been discussed with diminishedretinal blood circulation, does not show any differences in comparison with controlgroup and ultra sonography has less value for screening of asymptomatic carotidatherosclerosis

    Superradical Hysterectomy for Cervical Cancer as an Alternative to the Usual Okabayashi-Type Radical Hysterectomy

    Get PDF
    Radical hysterectomy is a standard operation for invasive cervical cancers. However, if the invasion to the parametrium is more advanced than estimation in the operation, it is difficult to perform usual radical hysterectomy. Superradical hysterectomy was developed by Prof. Ryukichi Mibayashi of Kyoto University and was published in 1941, and has been performed for the limited cases by a part of Japanese gynecologic surgeons. Superradical hysterectomy is a procedure in which the soft tissues in the pelvis are removed en bloc by sequential processing of the internal iliac vessels, which leads to a complete dissection of the lymphatic tissue in the pelvis to the pelvic wall

    We successfully treated a case of facial asymmetry involved in unilateral mandibular condylar osteochondroma with ipsilateral mandibular condylectomy and contralateral ramus osteotomy. A female, 32-year 11-month of age, had a chief complaint of facial asymmetry which initiated about 10 years ago. A mirror image analysis using a non-contact 3D image scanner revealed that the soft tissue on the deviated side was protruded more than 5.50 mm compared with the non-deviated side. The patinet was diagnosed as facial asymmetry with a skeletal Class III jaw-base relationship caused by unilateral mandibular condylar osteochondroma. After 18 months of preoperative orthodontic treatment, ipsilateral condylectomy and contralateral sagittal split ramus osteotomy were performed. As the results of postoperative orthodontic treatment for 20 months, an ideal occlusion having a Class I molar relationship with an adequate interincisal relationship was achieved. Facial asymmetry and mandibular protrusion were dramatically improved, and the differences between the deviation and non-deviation sides were decreased to less than 1.11 mm. The acceptable occlusion and symmetric face were maintained throughout 1-year retention period. Conclusively, our results indicated the stability after condylectomy without condylar reconstruction in a patient with unilateral condylar osteochondroma

    Mechanisms of thrombin-Induced myometrial contractions: Potential targets of progesterone

    Intrauterine bleeding during pregnancy is a major risk factor for preterm birth. Thrombin, the most abundant coagulation factor in blood, is associated with uterine myometrial contraction. Here, we investigated the molecular mechanism and signaling of thrombin-induced myometrial contraction. First, histologic studies of placental abruption, as a representative intrauterine bleeding, revealed that thrombin was expressed within the infiltrating hemorrhage and that thrombin receptor (protease-activated receptor 1, PAR1) was highly expressed in myometrial cells surrounding the hemorrhage. Treatment of human myometrial cells with thrombin resulted in augmented contraction via PAR1. Thrombin-induced signaling to myosin was then mediated by activation of myosin light chain kinase- and Rho-induced phosphorylation of myosin light chain-2. In addition, thrombin increased prostaglandin-endoperoxidase synthase-2 (PTGS2 or COX2) mRNA and prostaglandin E2 and F2α synthesis in human myometrial cells. Thrombin significantly increased the mRNA level of interleukine-1β, whereas it decreased the expressions of prostaglandin EP3 and F2α receptors. Progesterone partially blocked thrombin-induced myometrial contractions, which was accompanied by suppression of the thrombin-induced increase of PTGS2 and IL1B mRNA expressions as well as suppression of PAR1 expression. Collectively, thrombin induces myometrial contractions by two mechanisms, including direct activation of myosin and indirect increases in prostaglandin synthesis. The results suggest a therapeutic potential of progesterone for preterm labor complicated by intrauterine bleeding

    A novel Rac1-GSPT1 signaling pathway controls astrogliosis following central nervous system injury

    Astrogliosis (i.e. glial scar), which is comprised primarily of proliferated astrocytes at the lesion site and migrated astrocytes from neighboring regions, is one of the key reactions in determining outcomes after CNS injury. In an effort to identify potential molecules/pathways that regulate astrogliosis, we sought to determine whether Rac/Rac-mediated signaling in astrocytes represents a novel candidate for therapeutic intervention following CNS injury. For these studies, we generated mice with Rac1 deletion under the control of the GFAP (glial fibrillary acidic protein) promoter (GFAP-Cre;Rac1(flox/flox)). GFAP-Cre;Rac1(flox/flox) (Rac1-KO) mice exhibited better recovery after spinal cord injury and exhibited reduced astrogliosis at the lesion site relative to control. Reduced astrogliosis was also observed in Rac1-KO mice following microbeam irradiation-induced injury. Moreover, knockdown (KD) or KO of Rac1 in astrocytes (LN229 cells, primary astrocytes, or primary astrocytes from Rac1-KO mice) led to delayed cell cycle progression and reduced cell migration. Rac1-KD or Rac1-KO astrocytes additionally had decreased levels of GSPT1 (G(1) to S phase transition 1) expression and reduced responses of IL-1β and GSPT1 to LPS treatment, indicating that IL-1β and GSPT1 are downstream molecules of Rac1 associated with inflammatory condition. Furthermore, GSPT1-KD astrocytes had cell cycle delay, with no effect on cell migration. The cell cycle delay induced by Rac1-KD was rescued by overexpression of GSPT1. Based on these results, we propose that Rac1-GSPT1 represents a novel signaling axis in astrocytes that accelerates proliferation in response to inflammation, which is one important factor in the development of astrogliosis/glial scar following CNS injury

    BACKGROUND: The Japan Society of Obstetrics and Gynecology and the Japan Association of Obstetricians and Gynecologists have issued the guidelines and recommendations on postpartum hemorrhage since 2010 and have been conducted widespread educational activities from 2012. The aim of this study was to investigate the impact of these efforts by the Societies to prevent maternal deaths due to obstetric hemorrhage on trends in epidemiology and management of severe postpartum hemorrhage in Japan. METHODS: A national retrospective cohort study was conducted using the national database of health insurance claims for the period 2012 and 2018. The subjects were all insured women who received a blood transfusion for postpartum hemorrhage. The primary endpoints of this study were hysterectomy and maternal mortality. The etiology of hemorrhage, treatment facility, type of procedure, and blood transfusion volume were tabulated. RESULTS: Women with postpartum hemorrhage that underwent transfusion increased from 3.5 to 5.5 per 1000 deliveries between 2012 and 2018. The most common cause of postpartum hemorrhage was atonic hemorrhage. After insurance coverage in 2013, the intrauterine balloon tamponade use increased to 20.3% of postpartum hemorrhages treated with transfusion in 2018, while the proportion of hysterectomy was decreased from 7.6% (2013-2015) to 6.4% (2016-2018) (p < 0.0001). The proportion of postpartum hemorrhage in maternal deaths decreased from 21.1% (2013-2015) to 14.1% (2016-2018) per all maternal deaths cases (p = 0.14). Cases with postpartum hemorrhage managed in large referral hospitals was increased (65.9% in 2012 to 70.4% in 2018) during the study period (p < 0.0001). CONCLUSIONS: The efforts by the Societies to prevent maternal mortality due to obstetric hemorrhage resulted in a significant decrease in the frequency of hysterectomies and a downward trend in maternal mortality due to obstetric hemorrhage

    The effect of celecoxib for treatment of preterm labor on fetuses during the second trimester of pregnancy: A pilot case series

    OBJECTIVE: Although cyclooxygenase inhibitors effectively suppress uterine contraction, constriction of the fetal ductus arteriosus (DA) and oligohydramnios are major concerns. Celecoxib, a selective cyclooxygenase 2 inhibitor, is a potential potent tocolytic agent, but there are no studies that have evaluated the beneficial or adverse effects of celecoxib use on fetuses for more than 48 hours in pregnant women. We therefore aimed to evaluate the effect of middle-long-term celecoxib administration on the fetus during the second trimester of pregnancy, particularly in terms of fetal DA and amniotic fluid volume. MATERIALS AND METHODS: We retrospectively extracted and reviewed data from patients with preterm labor who received celecoxib for tocolysis for more than 48 hours between 2016 and 2020. Celecoxib was used for tocolysis only when treatment of patients with conventional tocolytic agents was ineffective. Data on the peak systolic velocity in ductus arteriosus (PSV-DA) and the maximum vertical pocket (MVP) were collected. RESULTS: A total of 15 patients were eligible. The median gestational age at celecoxib introduction was 22.6 weeks, and the median period of administration was 9 days (range 3-40 days). The median gestational age at delivery was 27.1 weeks, and the median duration from initial celecoxib administration to delivery was 40 days. The Z scores of PSV-DA and MVP did not change significantly after celecoxib administration. During administration, PSV-DA exceeded the 95th percentile of the corresponding normal reference range in three cases, but the levels returned to normal after reduction or discontinuation of treatment. There was no oligohydramnios during the treatment. CONCLUSION: Celecoxib administration for more than 48 hours in the second trimester of pregnancy might be safe and tolerable in terms of fetal PSV-DA and amniotic fluid volume as long as careful ultrasound monitoring is performed. Celecoxib could be an alternative for preterm labor when conventional tocolysis is not effective
