BACKGROUND: Placental alpha microglobulin-1 (PAMG-1) and phosphorylated insulin-like growth factor-binding protein-1 (phIGFBP-1) have been studied in patients at risk for preterm birth with signs and symptoms of preterm labor. However, a direct comparison between these two biomarkers, alone or in combination with cervical length measurement with an adequate sample size, has been lacking to date. OBJECTIVE: To compare PAMG-1 test and the phIGFBP-1-1 test alone and in combination with cervical length measurement for the prediction of imminent spontaneous preterm birth of testing in pregnant women with symptoms of preterm labor in a tertiary care setting...

Cervical polyp is very rare in pregnancy, usually asymptomatic and small. There are several reports of different sizes of cervical polyp in pregnancy but, huge cervical polyp causing funnelling and shortening of cervical length was first reported in 2014. It was managed by polypectomy causing cervical length to return to normal value. We present the second case report in literature of a huge endocervical polyp in pregnancy that caused funnelling and shortening of cervical length. Unlike the earlier report this patient presented with preterm contractions and antepartum haemorrhage (APH)...
