background: preterm labor (ptl) is the main challenge in prenatal health care, leads to high rate of mortality and  increases cost of health services. to evaluate the preterm delivery (ptd)?related risk factors, we decided to measure nitrite oxide metabolites and cervical length (cl) as the diagnostic and predictive tools for ptd in women and response to tocolytic therapy.materials and methods:...

conclusions there is no statistically significant relationship between preterm delivery and type of sludge. results the prevalence of preterm delivery was 14/3%. the frequencies of term delivery in mothers with dense, light and no sludge were 78/6%, 82/1% and 96/4 % respectively, and for preterm delivery they were 21/4%, 17/9% and 3/6% respectively. but there was no statistically significant re...

objective: to investigate the clinical advantage of several prognostic factors for predicting preterm delivery. materials and methods: eighty and six patients with a singleton pregnancy admitted to vali-asr hospital underwent genetic amniocentesis between the 15th and 23th weeks were included in this study. maternal serum c-reactive protein (crp), transvaginal sonographic measurement of cervica...

background: spontaneous preterm labor is one of the common obstetrics problems causing several physical, psychological and economical outcomes. although due to these outcomes and the efficacy of cares for decreasing them, preterm labor screening is cost-effective and it is still one of the challenging issues in obstetrics. objective: in this study preterm labor screening by using cervical trans...

INTRODUCTION The study shows possibilities of transvaginal sonographic measurement of the cervix in prediction of premature birth risk. GOALS The aim of the study was to follow up the cervical length in the pregnant from 16(th) to 37(th) week, as well as to do a microbiological analysis of the vaginal and cervical flora and to identify relation between the cervical shortening and microbiologi...

OBJECTIVE To evaluate a universal transvaginal ultrasonogram cervical length screening program on the incidence of a cervical length 20 mm or less and adherence to the management protocol for a cervical length less than 25 mm. METHODS We conducted a prospective cohort study of women with singleton gestations 18 0/7 to 23 6/7 weeks of gestation eligible for universal transvaginal ultrasonogram...
