Cervical pessary for preventing preterm birth.
Summary of "Cervical pessary for preventing preterm birth."
Preterm delivery is a major health problem and contributes to more than 50% of the overall perinatal mortality. Cervical incompetence is one of the common causes of preterm birth to which different management strategies have been tried including cervical cerclage. Cervical cerclage is an invasive technique that needs anaesthesia and may be associated with complications. Moreover, there is still a matter of controversy regarding the efficacy and the group of patients which could benefit from this operation. Cervical pessary has been tried as a simple, non-invasive alternative that might replace the above invasive cervical stitch operation.
To evaluate the efficacy of cervical pessary for prevention of preterm birth in women with cervical incompetence. SEARCH
We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (May 2010), Current Controlled Trials and the Australian New Zealand Clinical Trials Registry (May 2010). SELECTION
We selected all published and unpublished randomised clinical trials comparing the use of cervical pessary with cervical cerclage or expectant management for prevention of preterm birth. We did not include quasi-randomised trials, cluster-randomised and crossover trials. DATA COLLECTION AND
Two review authors independently assessed trials for inclusion. MAIN
The search identified two trials which we excluded. Three additional trials are ongoing. This review contains no included studies. AUTHORS'
The review did not identify any well-designed randomised clinical trial in order to confirm or refute the benefit of cervical pessary. However, there is evidence from non-randomised trials that showed some benefit of cervical pessary in preventing preterm birth. We are waiting for the results of three ongoing randomised controlled trials, assessing the role of cervical pessary in women with short cervix. There is a need for further well-designed randomised controlled trials.

Preterm birth remains a considerable public health concern and priority. Little headway has been made in the prevention of preterm birth despite considerable research in this area. New ideas and treat...
About 13% of twins are born before 34 weeks and 7% before 32 weeks. The prediction of preterm birth in twins is based on the same tests as in singleton pregnancies. In twin pregnancies, the cut-off fo...
Preterm birth is a delivery that occurs at less than 37 completed weeks of gestation and it is associated with perinatal morbidity and mortality. Spontaneous preterm birth accounts for up to 75% of al...
Preterm birth is a major public health problem, with a global prevalence of 9.6% and over a million annual neonatal deaths. In a mouse model of preterm labor (PTL) induced by intravaginal administrati...
Recent discoveries suggest that T-regulatory lymphocytes (Treg) might play an important role in the pathophysiology of preterm labor. The aim of this study was to assess the relationship among the lev...
Placement of a vaginal pessary reduces significantly the rate of spontaneous preterm birth in pregnant women with short cervical length at 18-22 weeks scan.
The aim of the study is to determine the effect of cerclage pessary on the incidence of spontaneous delivery between randomization (at 20-24+6 weeks) and 33+6 weeks in asymptomatic women w...

Medical and Biotech [MESH] Definitions
A parameter usually used in PRENATAL ULTRASONOGRAPHY to measure the length of the uterine neck (CERVIX UTERI). Cervical length or its shortening is used to identify and prevent early cervical opening and PRETERM BIRTH.
A network of nerve fibers originating in the upper four cervical spinal cord segments. The cervical plexus distributes cutaneous nerves to parts of the neck, shoulders, and back of the head, and motor fibers to muscles of the cervical spinal column, infrahyoid muscles, and the diaphragm.
Drugs that prevent preterm labor and immature birth by suppressing uterine contractions (TOCOLYSIS). Agents used to delay premature uterine activity include magnesium sulfate, beta-mimetics, oxytocin antagonists, calcium channel inhibitors, and adrenergic beta-receptor agonists. The use of intravenous alcohol as a tocolytic is now obsolete.
Postnatal deaths from BIRTH to 365 days after birth in a given population. Postneonatal mortality represents deaths between 28 days and 365 days after birth (as defined by National Center for Health Statistics). Neonatal mortality represents deaths from birth to 27 days after birth.
Official certifications by a physician recording the individual's birth date, place of birth, parentage and other required identifying data which are filed with the local registrar of vital statistics.
