Cervical Pessary for Prevention of Preterm Birth in Individuals With a Short Cervix: The TOPS Randomized Clinical Trial.

Importance: A short cervix as assessed by transvaginal ultrasound is an established risk factor for preterm birth. Study findings for a cervical pessary to prevent preterm delivery in singleton pregnancies with transvaginal ultrasound evidence of a short cervix have been conflicting. Objective: To determine if cervical pessary placement decreases the risk of preterm birth or fetal death prior to 37 weeks among individuals with a short cervix. Design, Setting, and Participants: We performed a multicenter, randomized, unmasked trial comparing a cervical pessary vs usual care from February 2017 through November 5, 2021, at 12 centers in the US. Study participants were nonlaboring individuals with a singleton pregnancy and a transvaginal ultrasound cervical length of 20 mm or less at gestations of 16 weeks 0 days through 23 weeks 6 days. Individuals with a prior spontaneous preterm birth were excluded. Interventions: Participants were randomized 1:1 to receive either a cervical pessary placed by a trained clinician (n = 280) or usual care (n = 264). Use of vaginal progesterone was at the discretion of treating clinicians. Main Outcome and Measures: The primary outcome was delivery or fetal death prior to 37 weeks. Results: A total of 544 participants (64%) of a planned sample size of 850 were enrolled in the study (mean age, 29.5 years [SD, 6 years]). Following the third interim analysis, study recruitment was stopped due to concern for fetal or neonatal/infant death as well as for futility. Baseline characteristics were balanced between participants randomized to pessary and those randomized to usual care; 98.9% received vaginal progesterone. In an as-randomized analysis, the primary outcome occurred in 127 participants (45.5%) randomized to pessary and 127 (45.6%) randomized to usual care (relative risk, 1.00; 95% CI, 0.83-1.20). Fetal or neonatal/infant death occurred in 13.3% of those randomized to receive a pessary and in 6.8% of those randomized to receive usual care (relative risk, 1.94; 95% CI, 1.13-3.32). Conclusions and Relevance: Cervical pessary in nonlaboring individuals with a singleton gestation and with a cervical length of 20 mm or less did not decrease the risk of preterm birth and was associated with a higher rate of fetal or neonatal/infant mortality.

Piometra secundario a estenosis cervical en una adolescente / Pyometra secondary to cervical stenosis in an adolescent

INTRODUCCIÓN: El piometra es una afección infrecuente, pero grave, que en general se diagnostica en mujeres posmenopáusicas. En adolescentes es sumamente raro, y si se acompaña de amenorrea primaria hay que tener en mente las anomalías congénitas. CASO CLÍNICO: Adolescente de 13 años, sin antecedentes personales de interés salvo amenorrea primaria, que acude con abdomen agudo y es intervenida por una peritonitis difusa causada por un piometra secundario a disgenesia (estenosis) cervical congénita. Se realizó dilatación cervical y se dejó una sonda vesical intrauterina para prevenir la reestenosis. CONCLUSIONES: Un diagnóstico precoz y un tratamiento conservador con dilatación cervical y colocación temporal de un catéter urinario son esenciales para un manejo seguro y efectivo de la estenosis cervical en adolescentes.

INTRODUCTION: Pyometra is an uncommon but serious condition that is generally diagnosed in postmenopausal women. In adolescents it is extremely rare; if accompanied by primary amenorrhea, consider congenital abnormalities. CASE REPORT: A 13-year-old adolescent, with no relevant personal history except primary amenorrhea, who presented with an acute abdomen and was operated on for diffuse peritonitis caused by pyometra secondary to congenital cervical dysgenesis (stenosis). Cervical dilation was performed and a urinary catheter was temporarily placed inside the uterus to prevent restenosis. CONLUSIONS: An early diagnosis and conservative treatment with cervical dilation and temporary placement of a urinary catheter are essential for the safe and effective management of cervical stenosis in adolescents.

Management of Cervical Ectopic Pregnancies: A Scoping Review.

OBJECTIVE: To investigate published cases of cervical ectopic pregnancy between 2000 and 2018 and compare management strategies and treatment success rates based on initial patient characteristics. METHODS: PubMed, EMBASE, and Web of Science were searched to capture peer-reviewed citations published between 2000 and 2018. Cases reporting either ß-hCG level, crown-rump length, or gestational sac diameter for each individual patient were included. Data regarding the article information, patient characteristics, treatment used, and outcomes were collected. Initial success was defined as resolution of the cervical ectopic pregnancy with the predefined treatment plan. Initial failure was defined as the requirement of additional unplanned interventions due to the predefined treatment plan not being successful. End success was defined as resolution of the cervical ectopic pregnancy without hysterectomy. RESULTS: A total of 204 articles from 44 countries comprising 454 cases were reviewed. The initial ß-hCG level ranged from 9 to 286,500, with a median of 14,773, and gestational age ranged from 4 to 18 weeks, with an average of 7 4/7 weeks (±2 0/7 weeks). In looking at initial success, compared with methotrexate alone, dilation, and curettage (odds ratio [OR] 2.26; 95% CI 2.64-10.45), dilation and curettage combined with uterine artery embolization (OR 4.85; 95% CI 2.06-11.44) and uterine artery embolization (OR 5.17; 95% CI 1.14-23.53) were more effective options. More than half of patients (50.2%) required multiple interventions, and 41 (9%) resulted in hysterectomy. CONCLUSIONS: Management of cervical ectopic pregnancies should be guided by patient stability, ß-hCG level, size of pregnancy, and fetal cardiac activity but may benefit from a planned multimodal approach.

The impact of cryotherapy for symptomatic cervical ectropion on female sexual function and quality of life.

In rare cases, cervical ectropion causes symptoms such as abundant leucorrhoea, postcoital bleeding, recurrent cervicitis, pelvic pain, and dyspareunia. Cryotherapy is a commonly used treatment for symptomatic cervical ectropion. We assessed the impact of cryotherapy on sexual function and quality of life among patients with symptomatic cervical ectropion. In this prospective observational study, 73 patients were assessed before and six months after cryotherapy treatment using the Female Sexual Function Index (FSFI) and Short Form-12 Health Survey questionnaires. The double-freeze cryotherapy procedure was performed using a cryotherapy unit, and liquid nitrogen was used as a refrigerant. The mean physical and mental quality of life scores were significantly improved after treatment. With the exception of the pain domain, the overall and domain FSFI scores exhibited no significant differences before and after cryotherapy. The sexual pain domain scores were significantly increased after treatment. There was a statistically significant improvement in vaginal discharge, pelvic pain, and postcoital bleeding symptoms after the cryotherapy. We concluded that cryotherapy is an effective and feasible treatment for symptomatic cervical ectropion. Although cryotherapy results in improved quality of life scores, it has no significant impact on female sexual function.Impact statementWhat is already known on this subject? Cryotherapy is the most preferred treatment option for symptomatic cervical ectropion. Its feasibility and effectiveness with respect to symptom relief have been observed in previous studies. No study has evaluated quality of life and sexual function after cryotherapy among patients with symptomatic cervical ectropion.What do the results of this study add? Although the patients' quality of life scores were significantly improved after treatment, no significant improvement was observed in overall and domain sexual function scores, with the exception of the pain domain. The sexual pain domain scores were significantly improved after cryotherapy.What are the implications of these findings for clinical practice and/or further research? Patients should not expect better sexual function after cryotherapy. Comparative studies should seek to identify the ideal treatment option, which would result in both symptom relief and better sexual function.

Uterine Artery Pseudoaneurysm in a Pregnant Patient with Retrocervical Endometriosis.

A pseudoaneurysm of the uterine artery or its branches is usually a result of vascular trauma during invasive procedures such as a cesarean section, vaginal delivery, myomectomy, hysterotomy, or dilatation and curettage. A uterine artery pseudoaneurysm rupture is a rare, yet life-threatening event. Deep infiltrating endometriosis usually involves a decrease in symptoms and imaging findings throughout pregnancy, with the notable exception of the phenomenon of decidualization. We present the case of a pregnant woman with a recent diagnosis of endometriosis, who conceived spontaneously and presented with disabling pain at 13 weeks' gestation. She was diagnosed with a left, huge (and rapidly growing) retrocervical endometriosis nodule encompassing a uterine artery pseudoaneurysm. Selective transarterial embolization was performed at 22 weeks' gestation owing to enlargement of the pseudoaneurysm sac, and the pseudoaneurysm was obliterated successfully. The patient was followed intensively throughout the pregnancy and the baby was delivered at term by cesarean section. After delivery, the nodule returned to the pregestational size.

Delivery through cervicovaginal fistula - literature review and case report.

Less than 10 deliveries via cervicovaginal fistula (CVF) with closed cervical os were reported so far. In the majority of cases, the patients had a history of induced abortions. The CVF was usually recognized due to postpartum hemorrhage. The facilitating role of prostaglandins used for labor induction was supposed. In all cases, the babies remained unaffected by the delivery route. We report a new case of a 37-year-old gravida 2, para 0, with a history of a paracervical tear following a first trimester abortion 11 years ago. The abortion and the laceration were not reported in the current obstetrical documentation. After labor induction using oral misoprostol in the 41 + 5 weeks of pregnancy, the patient delivered a healthy baby through a left-sided CVF, which imposed as bleeding paracervical laceration, 6 cm in diameter, extending to the vaginal fornix in the 3 o'clock position. The cervical os was only 1-1.5 cm dilated and imposed as an inelastic band ("squid ring") in the 9 o'clock position. The laceration was sutured under spinal anesthesia. The patient recovered quickly, and the postpartum hemoglobin drop was 2.8 g/dl. In conclusion, the possibility of CVF should be considered in women with a history of induced abortion.

Effects of Maintenance on Quality of Performance of Cryotherapy Devices for Treatment of Precancerous Cervical Lesions.

OBJECTIVE: The aim of the study was to evaluate the impact of maintenance on performance of cryosurgical equipment used in El Salvador primary health clinics. MATERIALS AND METHODS: Nine gynecological cryotherapy devices used in El Salvador were bench tested against a new machine of the same make and model. The devices were run for five successive double-freeze cycles. The El Salvador machines then received maintenance by a specialized engineer and another double-freeze cycle was performed. Temperature at the device probe tip was recorded throughout each cycle and ballistic gelatin was used as the tissue analogue to measure freeze ball dimensions achieved by the devices. Outcome measures were mean lowest-sustained temperatures and freeze ball mean weight, depth, and diameter. Paired and unpaired t tests were used to compare results premaintenance versus postmaintenance and postmaintenance versus the reference, respectively. RESULTS: Premaintenance versus postmaintenance freeze ball dimensions were significantly different (mean differences in weight = 2.31 g, p = .01; depth = 2.29 mm, p = .03; diameter = 3.51 mm, p = .02). However, postmaintenance dimensions were not significantly different than those of the reference (weight = 7.44 g vs. 8.39 g, p = .07; depth = 10.71 vs. 11.24 mm, p = .1; diameter = 31.38 mm vs. 32.05 mm, p = .3). Postmaintenance, minimum, and lowest-sustained temperatures were within the recommended clinical range. CONCLUSIONS: Specialized maintenance was necessary for heavily used cryotherapy devices to perform adequately, highlighting the challenges of gas-based cryotherapy in low- and middle-income countries.

[Double-balloon catheter compared to vaginal dinoprostone for cervical ripening in obese women at term]. / Comparaison sonde à double ballonnet-dinoprostone pour la maturation cervicale chez les femmes obèses à terme.

OBJECTIVE: To compare the efficacy of a double-balloon catheter versus vaginal prostaglandin E2 (dinoprostone) for cervical ripening in obese patients with unfavorable cervix at term. METHODS: The study had an open-label, prospective combined with retrospective, observational design. From January 2013 until May 2016, a prospective cohort study of 46 women with pre-pregnancy BMI>30kg/m2, live singleton term fetuses (>37 weeks) in vertex presentation and unfavorable cervix (Bishop score<6), who underwent labor induction for conventional indications using a double-balloon catheter. In the same period, 46 obese women who had undergone cervical ripening using vaginal dinoprostone (3mg) were retrospectively included. Women in groups were paired according to Bishop score before the insertion, pre-pregnancy BMI and parity. The primary outcome was a favorable cervix (Bishop score ≥6) 24h after cervical ripening. RESULTS: After 24h, there was a significantly higher rate of women with favorable cervix (Bishop score ≥6) in the double-balloon group than in dinoprostone group (80.4% vs 47.8%; P=0.001). After adjustment, a double-balloon catheter was significantly associated with an efficient cervical ripening compared to vaginal dinoprostone (aOR 7.81, 95% CI 2.58-23.60). No difference was observed in cesarean section rate (39.1% in each group; P=0.96) and in mean induction time to vaginal delivery (34.5h in the balloon group vs 36.5h in the dinoprostone group; P=0.53). Maternal and neonatal outcomes were similar. CONCLUSION: For obese patients at term, cervical ripening using a double-balloon catheter is more efficient on Bishop score after 24h compared to vaginal dinoprostone.

Health-related quality of life as measured by the EQ-5D in the prevention, screening and management of cervical disease: A systematic review.

PURPOSE: Cost-effectiveness analyses (CEAs) of screening can be highly sensitive to the health-related quality of life (HRQoL) effects of screen tests and subsequent treatment. Accordingly, accurate assessment of HRQoL is essential. We reviewed the literature regarding HRQoL in cervical prevention and management in order to appraise the current evidence regarding this important input to CEA. METHODS: We searched the MEDLINE, Scopus and EconLit databases for studies that estimated HRQoL in cervical cancer prevention and management published January 1995-December 2015. The primary inclusion criterion was for studies that assess HRQoL using the EQ-5D. Data were abstracted from eligible studies on setting, elicitation group, sample size, elicitation instruments, health state valuations, study design and follow-up. We assessed the quality and comparability of the studies with a particular focus on the HRQoL reported across states and groups. RESULTS: Fifteen papers met the inclusion criteria. Most used patient elicitation groups (n = 11), 2 used the general public and 2 used a mix of both. Eight studies were cross-sectional and seven were longitudinal. Six studies used both the EQ-5D-3L and the EQ-VAS together with other measures of overall HRQoL or condition-specific instruments. Extensive heterogeneity was observed across study characteristics. CONCLUSIONS: Our results reveal the challenges of sourcing reliable estimates of HRQoL for use in CEAs of cervical cancer prevention and treatment. The EQ-5D appears insufficiently sensitive for some health states. A more general problem is the paucity of HRQoL estimates for many health states and their change over time.

The Effect of Cryotherapy on Human Papillomavirus Clearance Among HIV-Positive Women in Lusaka, Zambia.

OBJECTIVE: We sought to investigate the progression of human papillomaviruses (HPV) infection in HIV-positive women after cryotherapy. METHODS: We examined changes in detection of high-risk HPV (hrHPV) cervical infections among HIV-infected women over a 12-week period after cryotherapy using stored specimens from a cohort study conducted between June 2009 and March 2011 in Lusaka, Zambia. Samples from visits at baseline and weeks 4, 8, and 12 were tested using the Roche Linear Array assay. RESULTS: A total of 89 women were included in the analysis. The median age was 32 years (interquartile range [IQR], 28-36 years). The median CD4+ cell count was 350 cells/µL (IQR, 214-470 cells/µL), and 66% of women were receiving antiretroviral therapy. At baseline, the prevalence of hrHPV was 91% (95% confidence interval [CI], 83%-95%). HPV45 was the most common HPV type, present in (30%) women, followed by HPV16 (27%), HPV18 (27%), HPV51 (20%), and HPV58 (22%). Among women with valid results both at baseline and 12 weeks, 25% (17/67) cleared their initial hrHPV infection within 12 weeks of treatment, although 65% (11/17) had new hrHPV types detected. CONCLUSIONS: Cryotherapy led to clearance of 25% of hrHPV infections within 12 weeks of treatment. However, hrHPV infection remained persistent in most women, and new hrHPV types were detected often, explaining the high rate of persistence and recurrence of cervical disease in this population. Continued efforts to scale up HPV vaccination and cervical screening should remain a priority in high HIV burden settings such as Zambia.

Incidence, risk factors and treatment of cervical stenosis after radical trachelectomy: A systematic review.

PURPOSE: Cervical stenosis is a major and specific postoperative complication following radical trachelectomy. The current article presents a review of studies describing the incidence, risk factors and treatment methods of cervical stenosis after this fertility sparing procedure. METHODS: We searched PubMed, MEDLINE, Embase (January 1994 through November 2014) using the following terms: uterine cervix neoplasms, cervical cancer, radical trachelectomy, fertility sparing and fertility preservation. We included original articles and case series. Case reports, review articles, articles not in English and articles not mentioning cervical stenosis were all excluded. RESULTS: We identified 1547 patients. The incidence rates of cervical stenosis ranged from 0% to 73.3% with an average rate of 10.5%. Among patients with abdominal, vaginal, laparoscopic and robotic radical trachelectomy, the incidences of cervical stenosis were 11.0%, 8.1%, 9.3% and 0%, respectively. In patients in whom whether cerclage was placed or not, the incidence rates of cervical stenosis were 8.6% and 3.0%, respectively (P=NS). Among those in whom whether anti-stenosis tools were placed or not, the incidences of cervical stenosis were 4.6% and 12.7%, respectively (P<0.001). Cervical stenosis was a potential cause of infertility and increased the use of artificial reproductive technology. Surgical dilatation resolved stenosis in the majority of cases but had to be repeated. CONCLUSIONS: Cervical stenosis is related to the surgical approach, cerclage and anti-stenosis tools utilised. It affects not only the quality of life but also obstetrical outcomes of patients following radical trachelectomy. Greater attention should be given to the prevention and treatment of this complication.

Efficacy and safety of focused ultrasound versus microwave therapy for cervical ectopy: a meta-analysis.

OBJECTIVES: To assess the efficacy and safety of focused ultrasound therapy (FU) and microwave therapy (MW) for cervical ectopy (CE). METHODS: We searched PubMed, EMbase, the Cochrane Library, Chinese Biomedical Literature Database (CBM), Chinese Scientific Journals Database (VIP), China Academic Journals Full-text Database (CNKI), and WanFang Data for randomized controlled trials (RCTs) comparing FU with MW for women with symptomatic CE from inception to 30 August 2014. Two review authors (Tang XL and Gao Z) independently screened for eligible studies according to the inclusion and exclusion criteria, extracted data and assessed risk of bias of included RCTs. Then, meta-analysis was performed using the RevMan 5.2 software. Funnel plots were used to evaluate publication bias. RESULTS: A total of 33 RCTs with 11,759 participants were included. All studies had high risk of bias. The results of meta-analysis indicated that compared to MW, FU significantly reduced the risk of vaginal bleeding (RR = 0.09, 95%CI 0.05 to 0.17, P < 0.00001) and vaginal discharge (RR = 0.10, 95%CI 0.04 to 0.24, P < 0.00001), increased the cure rate (RR = 1.10, 95%CI 1.05 to 1.15, P < 0.0001) and the total effectiveness rate (RR = 1.04, 95%CI 1.02 to 1.06, P = 0.0005), and decreased the recurrence rate (RR = 0.13, 95%CI 0.02 to 1.00, P = 0.05); however, this last difference was not statistically significant. CONCLUSION: Current available evidence suggests that FU is safer and more effective than MW for treating CE. However, some limitations will reduce the reliability of our results. Further well-designed clinical trials are needed to provide further clarification.

[First year experience using arabin cervical pessary with intravaginal micronized progesterone for the prevention of preterm birth in patients with mid-trimester short cervix].

BACKGROUND: Arabin cervical pessary is a silicone ring pessary for the prevention of preterm birth (PTB] for pregnant women at risk with second trimester short uterine cervix. Progesterone supplementation has been found to prevent PTB. OBJECTIVE: To review our first year of experience using Arabin cervical pessary with intravaginal micronized progesterone in the prevention PTB. METHODS: The study included patients (pt) with singleton and twin pregnancies at 16-30 weeks with uterine cervical length < or = 25 mm treated with Arabin cervical pessary and intravaginal progesterone over one year from September 2011 to September 2012. Progesterone treatment was continued until 34 weeks and pessary was extracted at 36 weeks or in cases of preterm labor, bleeding or other medical indications. RESULTS: The study group included 43 patients, 31 (72.1%) singleton and 12 (27.9%) twins. The average week at admission was 25+2 weeks [w] [SD +/- 3.05], and the average cervical length at admission was 13.5 mm (SD +/- 5.0). A total of 11 patients had previous PTB; in 2 patients the pessary was placed after cerclage failure. The average week of delivery was 35 + 5 weeks SD +/- 3.2 (singleton 36 + w SD +/- 2.6, twins 33 + 4 SD +/- 4.1, p = 0.05); the average time between pessary insertion to delivery 72.1 days SD +/- 26.2 (singleton 76.3 SD +/- 22.9 twins 60.2 SD +/- 28.9 p = 0.02), in 23 patients (53.5%) the pessary was extracted at > or = 36 + 6w, 5 patients 111.6%) delivered < or = 32w (2 singleton, 3 twins, p = 0.08) and 18 patients (41.8%) reported increased vaginal discharge. CONCLUSION: The use of cervical pessary in conjunction with intravaginal progesterone is safe and feasible. Patients with twin pregnancies had a significantly higher rate of preterm birth compared to singleton pregnancies. Further research is needed to assess device efficacy.

Isolated hydatid cyst of uterine cervix: A case report.

Hydatid disease is an endemic infection which can affect any organ, mainly the liver and lungs. Peritoneal echinococcosis is usually known to occur secondary to hepatic hydatid cyst rupture into the peritoneal cavity. An isolated cyst in the pelvic cavity is considered as primary only when there are no other hydatid cysts. Herein, we report an isolated pelvic-cervical hydatid cyst which presented without any involvement of the other abdominal organs or lungs. Our patient, a 27-year-old woman with the primary complaints of dyspareunia and chronic pelvic pain, had thin-walled large cystic mass originating from the cervix, diagnosed by ultrasonography. She underwent surgery with the most likely initial diagnosis of exophytic fibroid with cystic degeneration. Gynecologists should be aware of the possibility of isolated primary hydatid cyst of the pelvic cavity and should consider this condition in the differential diagnosis of cystic pelvic masses, especially in areas where the disease is endemic.

Citología vaginal o papanicolau / Vaginal cytology or pap

Según el Instituto Nacional de Estadística y Geografía, durante 2010 uno de los principales tumores malignos que afectó a la población femenina adulta (de 20 años y más) en México fue el cervicouterino (9.7%). El método diagnóstico para cualquier alteración histopatológica es la citología vaginal, que es reconocido porprogramas de control y prevención del cáncer como una de las pruebas que ha reducido la incidencia y mortalidad provocadas por este padecimiento, gracias a su pronta detección. Es por ello la relevancia de este estudio y la reiteración en la exploración continua de tejidos sensibles.

According to the National Institute of Statistics and Geography in Mexico during 2010, one of the major malignancies affecting the adult female population (20 years and over) is the cervical (9.7%). The method for any alteration histopathological diagnosis is the vaginal cytology, as it is recognized by control programs and cancer prevention as one of the tests has reduced the incidence and mortality caused by this disease, thanks to early detection. That is why the importance of this study and repeated in continuousexploration of sensitive tissues.

Unique complication of a Shirodkar cerclage: remote formation of a vesicocervical fistula in a patient with the history of cervical cerclage placement: a case report and literature review.

BACKGROUND: Cervical cerclage placement is an accepted treatment for cervical insufficiency and recurrent second-trimester pregnancy loss. The most commonly described complications of cerclage include rupture of fetal membranes, intra-amniotic infection, endometritis, and peripartum bleeding. We present a unique case of a vesicocervical fistula formation remote from cerclage placement. CASE: A vesicocervical fistula was diagnosed in a 51-year-old patient who presented with a chief complaint of vaginal bleeding. The fistula was found on cystoscopic examination after the extrusion, from the cervix, of Mersilene tape from a Shirodkar cerclage placed 13 years earlier for management of cervical insufficiency. CONCLUSION: Although the presented condition was managed conservatively, one should discuss remote formation of urogenital fistulae as a rare complication of cervical cerclage at the time of informed consent.

Activity restriction among women with a short cervix.

OBJECTIVE: To estimate determinants of and outcomes associated with activity restriction among women with a short cervix. METHODS: This was a secondary analysis of a randomized trial of 17-α hydroxyprogesterone caproate for prevention of preterm birth among nulliparous women with singleton gestations and cervices less than 30 mm by midtrimester ultrasonography. Women were asked weekly whether they had been placed on pelvic, work, or nonwork rest. "Any activity restriction" was defined as being placed on any type of rest. Factors associated with any activity restriction were determined and the association between preterm birth and activity restriction was estimated with multivariable logistic regression. RESULTS: Of the 657 women in the trial, 646 (98%) responded to questions regarding activity restriction. Two hundred fifty-two (39.0%) were placed on any activity restriction at a median of 23.9 weeks (interquartile range 22.6-27.9 weeks). Women on activity restriction were older, more likely to have private insurance, less likely to be Hispanic, had a shorter cervical length, and were more likely to have funneling and intra-amniotic debris. Preterm birth at less than 37 weeks of gestation was more common among women placed on activity restriction (37% compared with 17%, P<.001). After controlling for potential confounding factors, preterm birth remained more common among those placed on activity restriction (adjusted odds ratio 2.37, 95% confidence interval 1.60-3.53). Results were similar for preterm birth at less than 34 weeks of gestation. CONCLUSION: Activity restriction did not reduce the rate of preterm birth in asymptomatic nulliparous women with a short cervix.

Short cervix syndrome: current knowledge from etiology to the control.

BACKGROUND: Preterm delivery is one of the most serious public health problems and is the most important factor relating to neonatal morbidity and mortality. The strategies for preventing it include understanding the risk factors, with specific interventions. Recently, uterine cervix measurements using ultrasonography and vaginal administration of progesterone have gained importance in predicting and secondarily preventing spontaneous preterm delivery. OBJECTIVE: To describe the short cervix syndrome, including its etiology, diagnosis, and possible therapies. METHODS: Research in ISI, Pubmed, and Scielo database using the words short cervix, preterm delivery, sludge, cervical funneling, cervical gland area, progesterone, cerclage, and pessary. RESULTS: We found a lot of articles about this topic, including randomized controlled trials. The etiology is multifactorial, being the diagnosis based in a cervix shortening at 20-24 weeks. The history and measurement of cervix length by transvaginal ultrasound have been shown to be effective to select the high risk pregnancies. The progesterone, cervical cerclage, and cervical pessary showed to be effective to reduce the preterm delivery in pregnant women with short cervix. CONCLUSION: The successful management of pregnant women presenting a short cervix depends on the understanding that cervical shortening is the final common path for several causes of preterm delivery. The best approach should be individualized to each patient.
