BACKGROUND: While there are well-accepted standards for the diagnosis of arrested active-phase labor, the definition of a "failed" induction of labor remains less certain. One approach to diagnosing a failed induction is based on the duration of the latent phase. However, a standard for the minimum duration that the latent phase of a labor induction should continue, absent acute maternal or fetal indications for cesarean delivery, remains lacking. OBJECTIVE: The objective of this study was to determine the frequency of adverse maternal and perinatal outcomes as a function of the duration of the latent phase among nulliparous women undergoing labor induction...

BACKGROUND AND PURPOSE: Aneurysms in various arterial beds have common risk- and genetic factors. Data on the correlation of extracranial carotid artery aneurysms (ECAA) with aneurysms in other vascular territories are lacking. We aimed to investigate the prevalence of ECAA in patients with an intracranial aneurysm (IA). METHODS: We used prospectively collected databases of consecutive patients registered at the University Medical Center Utrecht with an unruptured intracranial aneurysm (UIA) or aneurysmal Subarachnoid hemorrhage (SAH)...

Background: Traumatic extracranial internal carotid artery (ICA) dissections are uncommon and can be difficult to treat. Thinning of adventitia and dilatation may occur following arterial dissection, thus resulting in a fusiform pseudoaneurysm, which can subsequently cause bleeding, expanding, or pulsatile hematoma. Currently, medical management with anticoagulation remains the first line of treatment and yields good outcomes in 75% of cases with a mortality rate of 3-4%. Endovascular intervention is indicated with failure of medical therapy, progressive enlargement of a traumatic pseudoaneurysm, acute flow-related infarcts due to vessel occlusion, or when anticoagulation is contraindicated due to risk of pseudoaneurysm rupture and hemorrhage...

OBJECTIVES: To compare pregnancy outcomes of physical examination-indicated cerclage in twin pregnancies with acute cervical insufficiency with that of singletons. METHODS: This retrospective cohort study included 88 consecutive women (17 twins and 71 singletons) who had undergone physical examination-indicated cerclage because of acute cervical insufficiency (defined as painless cervical dilation with (1) prolapsed and/or visible membranes at the external cervical os on speculum examination and (2) a functional cervical length of zero on transvaginal ultrasound) between 160/7 and 236/7 weeks...

We conducted a questionnaire survey on the current obstetric management of preterm labor (PL) and preterm premature rupture of the membranes (pPROM). The questionnaire covered approximately a third of all preterm deliveries and nearly half of the preterm deliveries before 32 gestational weeks. The diagnostic criterion for PL was either painful uterine contractions or cervical dilatation. Tocolytic agents were primarily used as long-term maintenance therapy. Intrauterine infection was clinically diagnosed at most responding institutions...

OBJECTIVES: Cochlear implantation (CI) has been the most successful procedure for restoring hearing in a patient with severe and profound hearing loss. However, possibly owing to the variable brain functions of each patient, its performance and the associated patient satisfaction are widely variable. The authors hypothesize that peripheral and cerebral circulation can be assessed by noninvasive and globally available methods, yielding superior presurgical predictive factors of the performance of CI in adult patients with postlingual hearing loss who are scheduled to undergo CI...

OBJECTIVE: Antenatal corticosteroids before preterm births are considered to be most effective 48 h after and up to 1 week after the first dose. We aim to evaluate: (1) our practice of administration of antenatal corticosteroids in Singapore; (2) admission characteristics of women for discriminatory factors of spontaneous preterm delivery within 1 week. METHODS: This is a retrospective study in a tertiary obstetrics unit in Singapore. 3044 women who delivered live births (at term or preterm) from 1st November 2014 to 31st January 2015, who were at risk of spontaneous or induced preterm delivery, were included...

REVIEW
Janine S Rhoades, Alison G Cahill
Modern data have redefined the normal first stage of labor. Key differences include that the latent phase of labor is much slower than was previously thought and the transition from latent to active labor does not occur until about 6 cm of cervical dilatation, regardless of parity or whether labor was spontaneous or induced. Providers should have a low threshold to use one of the safe and effective interventions to manage abnormal progression in the first stage of labor, including oxytocin, internal tocodynamometry, and amniotomy...

PURPOSE: A model exists that predicts the probability of vaginal birth after cesarean (VBAC). That model is not stratified by indication at first cesarean. The aim of the study was to identify factors that may predict successful VBAC in patients operated for arrest of dilatation or descent at their first cesarean. METHODS: Retrospective analysis of all women with trials of labor after one cesarean (TOLAC) for non-progressive labor between November 2008 and October 2015 was performed (n = 231)...

BACKGROUND: In 2010 the Consortium on Safe Labor published labor curves. It was proposed that the rate of cesarean delivery could be lowered by avoiding the diagnosis of arrest of dilation before 6 cm. However, there is little information on the uptake of the guidelines and on changes in cesarean delivery rates that may have occurred. OBJECTIVE: The objective of the study was to test the following hypotheses: (1) among patients laboring at term, rates of arrest of dilation disorders have decreased, leading to a decrease in the rate of cesarean delivery; (2) in the second stage, pushing duration prior to diagnosis of arrest of descent has increased, also leading to a reduction in the rate of cesarean delivery for this indication...

OBJECTIVE: Fibrodysplasia ossificans progressiva (FOP) is an ultra-rare genetic disorder in which heterotopic bone forms in the soft tissues. This often occurs in response to injury or inflammation, leading to joint immobilization and significant disability. There are currently no definitive treatment options for this devastating disease. Although the most dramatic phenotype in FOP is the episodic and progressive heterotopic ossification, patients report a number of symptoms that affect other organ systems...

BACKGROUND: Postpartum hysterectomy is a life saving emergency procedure in the management of uncontrollable severe maternal hemorrhage that every obstetrician should be closely acquainted with despite developments in medical and non-surgical interventions for obstetric hemorrhage. It can be difficult to detect the real boundaries of the cervix at full effacement and dilatation in patients who undergo emergency hysterectomy after vaginal delivery. METHODS: Hereby we propose a simple and effective method to ease the operation by placing two atraumatic ring forceps to the anterior and posterior sides of the cervix during the preoperative vaginal examination and leave the two ring forceps while taking the patient into surgery...

REVIEW
Rupsa C Boelig, Vincenzo Berghella
Cervical insufficiency can be defined by a combination of obstetric history, cervical dilation on exam, and/or short cervical length in women with prior preterm birth. Options for mechanical intervention include cerclage and pessary. There is evidence to support the benefit of a cervical cerclage in women with singleton gestations who have a diagnosis of cervical insufficiency either based on second trimester painless cervical dilatation leading to recurrent early preterm births, or a history of early spontaneous preterm birth and a second trimester transvaginal ultrasound short cervical length or cervical dilation on exam...

Cyclooxygenase (COX)-derived prostaglandins stimulate uterine contractions and prepare the cervix for parturition. Prior reports suggest Cox-1 (Ptgs1) knockout (KO) mice exhibit delayed parturition due to impaired luteolysis, yet the mechanism for late-onset delivery remains unclear. Here, we examined key factors for normal onset of parturition to determine whether any could account for the delayed parturition phenotype. Pregnant Cox-1KO mice did not display altered timing of embryo implantation or post-implantation growth...
