STUDY OBJECTIVE: To describe the presentation, diagnosis, and management of a patient with abdominal pregnancy and to illustrate the laparoscopic technique used to manage this patient. DESIGN: A descriptive study approved by our local Institutional Review Board. Consent was given from the patient. SETTING: A university hospital in Ashdod, Israel. PATIENT: On May 15th 2018, a gravida 3, para 2, 37-year-old asymptomatic patient was referred to our hospital's gynecologic emergency department due to a suspected ectopic pregnancy...

We report a case of subclinical central diabetes insipidus (DI), due to Rathke's cleft cysts, that was initially misdiagnosed as transient DI of pregnancy because it presented in the third trimester of pregnancy. A 37-year-old primigravida visited the Department of Obstetrics in the 30th week of gestation due to polyuria. She was admitted due to oligohydramnios; the amniotic fluid index was 3.24. A vasopressin challenge test was performed and her urine osmolality increased by >100% from baseline after the administration of desmopressin...

INTRODUCTION: Uterine myomas are the most common benign tumors of the female reproductive tract with myomectomy being one of the major modalities of the treatment in our set up. The aim of this study was to share the experiences of open myomectomy from a Teaching Hospital. METHODS: A observational study was conducted from a records of myomectomy cases in the department of Obstetrics and Gynaecology at Nobel Medical College teaching Hospital from June 2014- May 2016...

This paper presents a case of a pregnant woman with a history of two cesarean sections. The patient was admitted to the hospital because of vaginal bleeding. The ultrasound revealed a placenta covering the internal os. The placenta was characterized by heterogeneous echogenicity with visible irregular hypoechogenic areas and blurred border between the placenta and the cervix. Rich vascularity was observed on the border of the placenta, urethra and the urinary bladder. Cystoscopy showed severe congestion around the urethra...

BACKGROUND: Cesarean scar ectopic pregnancies are rare, with an incidence of approximately 1 in 2,000 pregnancies. The trauma of a cesarean section and a subsequent cesarean scar pregnancy can lead to the formation of an arteriovenous malformation (AVM). The resulting intractable bleeding is difficult to manage and can result in an emergent surgical intervention that could jeopardize a female's ability to become pregnant in the future. CASE REPORT: A 29-year-old female, gravida 2 para 1, with 1 prior low transverse cesarean section had a presumed cervical ectopic pregnancy treated with intramuscular methotrexate...

OBJECTIVE: Early-onset pre-eclampsia is primarily associated with placental dysfunction, whereas late-onset pre-eclampsia is defined as a maternal constitutional disorder. As a protein cosynthesized with vasopressin, copeptin is a potential marker of metabolic syndrome and insulin resistance, which shares similar risk factors with pre-eclampsia. The aim of this study was to investigate the copeptin levels in patients with early-onset and late-onset pre-eclampsia. MATERIALS AND METHODS: A total of 80 pregnant women receiving antenatal and obstetric care were recruited...

OBJECTIVES: The objective of this study is to determine if chronic infusion of arginine vasopressin (AVP) during mouse pregnancy recapitulates the human phenotypes of preeclampsia. We hypothesize a causative role of elevated AVP in the pathogenesis of preeclampsia. METHODS: Wildtype C57Bl/6J females were chronically infused with AVP (24ng/h, s.c., or saline vehicle) before syngeneic mating. Systolic blood pressure during pregnancy was measured by tail-cuff plethysmography...

BACKGROUND. Oxytocin is a well known drug most commonly used in obstetrics for induction or augmentation of labor. Due to its essential role in labor, and the overall effect in the body, oxytocin must be deeply understood by all obstetricians who use it and prescribe it. There is relevant data listed about oxytocin and has reviewed the evidence in 31 full text articles of indexed journals between 1999 and 2013. In search engines like MEDLINE, MedicLatina, PUBMED, Wolters Kluwer Healt, with keywords like: oxytocin, oxytocin receptor, oxytocin vasopressin, oxytocin postpartum, oxytocin review, oxytocin labor, oxytocin release...

INTRODUCTION: To investigate the ability of cardiovascular plasma biomarkers to identify imminent preeclampsia (PE) among pregnant women at triage. MATERIAL AND METHODS: C-terminal pro-arginine vasopressin (copeptin), C-terminal pro-endothelin-1 (CT-proET-1), mid-regional pro-adrenomedullin (MR-proADM), and mid-regional pro-atrial natriuretic peptide (MR-proANP) were prospectively measured in pregnant women presenting at the obstetrical triage units of the University Hospitals of Basel and Zurich, Switzerland...

INTRODUCTION: Challenges of modern medicine are peripartum bleeding complications as one of the most frequent cases of emergency in obstetrics with a prevalence of 0.5-5.0 %, meaning the main cause of maternal morbidity and mortality. In this context, inherited diseases such as Hermansky-Pudlak syndrome (HPS) should be recognized. HPS is a rare disease and belongs to a heterogeneous group of autosomal recessive disorders characterized by the triad of partial oculocutaneous albinism, disorder of "ceroid" metabolism and platelet storage pool deficiency with bleeding disorder...

Oxytocin (OXT) is a neurohypophysial hormone which is synthesized in the paraventricular and supraoptic nuclei of the hypothalamus. OXT is currently attracting considerable attention because it has been discovered that it regulates various functions of behavior especially in the context of social interactions. OXT is a key component in bone formation, glycemia, male sexuality, cardiac differentiation and pregnancy and thus it is important to be further explored. The authors review various aspects of gestational diabetes, including definition, screening, diagnostic procedures, complications, clinical evaluation, indications of delivery and neonatal aspects...

INTRODUCTION: Evidence elucidating the pathophysiology and pharmacology of conventional drugs, β-2 stimulants and magnesium sulfate, on safety and effectiveness for preeclampsia and preterm labor are rarely found. Both compounds pass through the placental barrier and could exert their adverse effects on the fetus. Exposure to these agents could be problematic long after the birth, and possibly result in diseases such as autism and cardiomyopathy. Since 1970 the possible roles of placental aminopeptidases, which degrade peptide hormones, in preeclampsia and preterm labor have been studied...

BACKGROUND: Hermansky-Pudlak syndrome (HPS), a rare autosomal-recessive disorder encompassing multiple organs, is characterized by oculocutaneous albinism, platelet storage pool deficiency resulting in bleeding diathesis, and ceroid lipofuscin deposition which can lead to pulmonary fibrosis, colitis, cardiomyopathy and renal failure. Pregnancy in a patient with HPS can produce multiple complications such as peripartum hemorrhage and difficulties with administration of anesthesia, either regional or general...

The authors report the performance of a labour epidural analgesia in a 26-year-old parturient presenting a moderate factor XI (FXI) deficiency. If haemostasis disorders usually contraindicate an epidural analgesia (with a risk of epidural haematoma), a moderate FXI deficiency is not an absolute contraindication to perform such an epidural analgesia. Desmopressin, sometimes used in surgery to reduce the bleeding, was administered to withdraw the catheter in better haemostasis conditions. No neurological signs were observed...

BACKGROUND: Congenital bleeding disorders can cause obstetric haemorrhage during pregnancy, labour and following delivery. Desmopressin acetate is found to be an effective drug which can reduce the risk of haemorrhage and can also stop bleeding in certain congenital bleeding disorders. Its use in pregnancy has been controversial. Hence beneficial and adverse effects of desmopressin acetate in these groups of pregnant women should be evaluated. OBJECTIVES: To determine the efficacy of desmopressin acetate in preventing and treating acute bleeds during pregnancy in women with congenital bleeding disorders...

BACKGROUND: Both preeclampsia and preterm delivery are important complications in pregnancy and are still diseases of unknown causes, despite considerable research in recent times. These complications constitute obstetric emergencies that require expert knowledge and management skills. OBJECTIVES: This article reviews the emerging role of aminopeptidases in the monitoring and development of improved therapeutic strategies that provide better patient selection for therapeutic personalization...

STUDY OBJECTIVE: To describe temporary bilateral uterine artery occlusion with titanium clips in combination with vasopressin as an effective surgical intervention to control hemorrhage during laparoscopic management of cesarean scar pregnancies (CSPs). DESIGN: Retrospective study (Canadian Task Force classification III). SETTING: University hospital in an obstetrics and gynecology department. INTERVENTIONS: Five patients with CSPs underwent removal of gestational ectopic masses via laparoscopy...

Gestational diabetes insipidus is an uncommon clinical disease whose prevalence is approximately two to three pregnancies per 100,000. It may be isolated or associated with preeclampsia. We report a case of gestational diabetes insipidus in a twin pregnancy, originally isolated during two months, and secondarily complicated by HELLP-syndrome. We recall the specific pathophysiology of polyuric-polydipsic syndrome during pregnancy and summarize its various causes. Finally, we discuss the indications, in case of isolated gestational diabetes insipidus, of treatment by dDAVP...

Inherited bleeding disorders are especially problematic for affected girls and women due to the monthly occurrence of menstrual periods and the effects on reproductive health. Although heavy menstrual bleeding (HMB) is the most common manifestation, females with inherited bleeding disorders (FBD) experience other bleeding symptoms throughout the lifespan that can lead to increased morbidity and impairment of daily activities. The purpose of this article is to describe the utility of a female-focused surveillance effort [female Universal Data Collection (UDC) project] in the United States Haemophilia Treatment Centres (HTCs) and to describe the baseline frequency and spectrum of diagnoses and outcomes...

BACKGROUND: Vasopressin is one of the most important physiological stress and shock hormones. Copeptin, a stable vasopressin precursor, is a promising sepsis marker in adults. In contrast, its involvement in neonatal diseases remains unknown. The aim of this study was to establish copeptin concentrations in neonates of different stress states such as sepsis, chorioamnionitis and asphyxia. METHODS: Copeptin cord blood concentration was determined using the BRAHMS kryptor assay...
