Emergency cerclage outcomes for bulging fetal membranes: a single-center retrospective study.

Purpose: This study aimed to investigate the usefulness of emergency cerclage for pregnant women with bulging fetal membranes, as indicated by our original noninvasive clinical scoring system.

Methods: This was a retrospective study of pregnant women who underwent emergency cerclage for bulging fetal membranes within 28 weeks. The primary outcome was the continuation of pregnancy at 34 gestational weeks in singleton pregnancies and 32 gestational weeks in twin pregnancies.

Guidelines for obstetrical practice in Japan: Japan Society of Obstetrics and Gynecology and Japan Association of Obstetricians and Gynecologists 2020 edition.

The 2017 clinical guidelines for obstetrical practice by the Japan Society of Obstetrics and Gynecology and the Japan Association of Obstetricians and Gynecologists were revised and published as the 2020 edition (in Japanese). The aim of these guidelines is to present appropriate standard obstetric diagnosis and management procedures that have reached consensus among Japanese obstetricians. The 2020 guidelines include 113 clinical questions and an appendix, followed by answers (CQ&A; originally 112 in the 2017 edition), a discussion, list of references, and some tables and figures presenting common problems and questions encountered in obstetrical practice.

Sudden onset of syncope and disseminated intravascular coagulation at 14 weeks of pregnancy: a case report.

Background: Amniotic fluid embolism (AFE), also known as anaphylactoid syndrome of pregnancy (ASP), typically occurs during labor and may result in cardiorespiratory collapse and disseminated intravascular coagulation (DIC). There are reports describing less typical presentations of AFE/ASP in which patients do not necessarily have the classic triad of hypoxia, hypotension, and coagulopathy. AFE/ASP rarely occurs in the absence of labor, but such cases may involve medical or surgical abortion, spontaneous miscarriage, or obstetrical procedures including amniocentesis and amnioinfusion.

Diagnosis of Persistent Cloaca by Ultrasonography and MRI: A Case Report.

BACKGROUND Persistent cloacal malformations are rare anomalies that are anorectal malformations occurring in females. In cases of persistent cloaca, prenatal ultrasonography shows fetal ascites, cystic tumor in the abdomen, oligohydramnios, and hydronephrosis. There are various types of persistent cloaca, and symptoms vary.

Unilateral pulmonary agenesis associated with oesophageal atresia and tracheoesophageal fistula: A case report with prenatal diagnosis.

We describe herein a case of unilateral pulmonary agenesis (PA) with oesophageal atresia (EA)/tracheoesophageal fistula (TEF) that was diagnosed prenatally and repaired by esophagoesophagostomy with stable postoperative course. The patient was born at 34 weeks gestation, after ultrasonography at 22 weeks gestation showed possible right-sided diaphragmatic eventration or PA and EA was subsequently suspected due to hydramnios. The initial X-ray showed mediastinal shift to the right, and coil up sign of the nasogastric tube, without intracardiac anomaly.

Vitamin K prophylaxis and late vitamin K deficiency bleeding in infants: fifth nationwide survey in Japan.

Background: In 1980, the first nationwide survey on late vitamin K deficiency bleeding (VKDB) in infants was conducted in Japan, and it was followed by the second, third and fourth nationwide surveys in 1985, 1988 and 1991, respectively. The fifth nationwide survey was designed to ascertain the epidemiology of late VKDB between January 1999 and December 2004.

Patients And Methods: Questionnaires were sent to 2161 hospitals in Japan that employed members of the Japan Pediatric Society in March 2005.

Des-gamma-carboxyprothrombin (PIVKA-II) levels in maternal serum throughout gestation.

The status of vitamin K in pregnant women was investigated using the highly sensitive method for des-gamma-carboxyprothrombin (protein induced by vitamin K absence [PIVKA-II]), electrochemiluminescence immunoassay. A gradual elevation of PIVKA-II related to gestational weeks was observed in healthy pregnant women, suggesting that a modest vitamin K deficiency takes place in gestation. Furthermore, throughout gestation the majority of pregnant women exceeded the healthy adult levels in PIVKA-II.

Antiphospholipid syndrome: characteristics and obstetrical management.

Antiphospholipid syndrome (APS) is characterized by a combination of clinical features consisted of thrombotic or pregnancy-related events and autoimmune antiphospholipid antibodies. In the 1998 International Consensus Preliminary Criteria, APS is defined by the concomitant presence of these clinical features and laboratory tests, including solid immunoassay and lupus anticoagulant (LAC). Current concept of antiphospholipid antibodies directed against plasma proteins with affinity for negatively charged phospholipids, mainly beta2-glyoprotein 1 (beta2GP1) and prothrombin, that is, anti-beta2GP1 and anti-prothrombin antibodies have been shown as a key antibody in the APS, while the pathophysiological mechanisms remain still uncertain.

Improvement of vitamin K status of breastfeeding infants with maternal supplement of vitamin K2 (MK40).

The present study is aimed at evaluating the efficacy of maternal vitamin K2 supplementation on the vitamin K status of newborn infants using the measurement of des-gamma-carboxyprothrombin (PIVKA-II [protein induced by vitamin K absence]) and the hepaplastin test (HPT). PIVKA-II and HPT were measured at the 1st month of age in two groups: 31 infants with maternal vitamin K supplementation (15 mg/d Menatetrenone since the 14th day after parturition) (group 1) and 46 without maternal supplementation (group 2). All infants received vitamin K2 syrup twice within the 1st week of life.

Anticholinergics induce eclamptic seizures.

Severe preeclampsia is a pathophysiological disorder specific to pregnancy and characterized by vasoconstriction and hypercoagulability. Eclampsia (convulsion associated with preeclampsia) and hemolysis, elevated liver enzymes, and low platelet count associated with preeclampsia (HELLP syndrome) are serious complications in patients with severe preeclampsia. They are thought to be characterized by generalized vasoconstriction and reduction in blood flow to various organs that may be explained by increased sensitivity of the vascular smooth muscles and increased vasopressors.

Coagulation index to distinguish severe preeclampsia from normal pregnancy.

The purpose of this study was to establish a new coagulation index to distinguish severe preeclampsia from normal pregnancy using optimal coagulation parameters. The difference between platelet counts in early gestation and before delivery (DeltaPlt = [platelet counts before delivery] - [platelet counts in early gestation]) was calculated as an index of changes in platelet counts. Antithrombin (AT) activity, thrombin-antithrombin (TAT) complex, fibrin degradation products (FDP) D-dimer, and DeltaPlt were investigated in 72 cases of normal pregnant women in the third trimester of pregnancy and 56 cases of severe preeclampsia.
