Infant mortality is considered as the key healthcare index in every country. The outcomes of a preterm birth are among the main and direct causes of neonate mortality. Therefore, the present research aims to investigate some maternal factors influencing the immature birth.
This observational case study was conducted on 100 term babies as the control group. The questionnaires were completed through interviewed mothers or perused hospital files.
The results of this study showed the high chances of premature birth in women with multiple pregnancies, smoking, placenta previa, uterine problems and placental abruption compared to most of the mothers with no history of such problems. In mothers with cervical incompetence, the chances of delivering a preterm baby are 11 times as high as mothers with no such problems. Similarly, the chances are 9.33 times as high among the mothers who had a history of placenta previa.
Identifying maternal factors influencing the preterm infant birth as well as attentive care taken during pregnancy can significantly reduce the preterm infant birth.

Ectopic cervical pregnancy is a rare clinical condition and the most common symptom is vaginal bleeding that has differential diagnosis with placenta previa. Transvaginal sonography is helpful in diagnosis and three-dimensional ultrasound and Magnetic resonance imaging (MRI) help in confirming the diagnosis. Case report: A 25 year old primigravid woman with painless vaginal bleeding during the first trimester and an ultrasound assessment in 14th week of pregnancy that showed complete placenta previa and repeated vaginal bleeding in second and third trimester underwent cesarean delivery in 37th week of pregnancy due to beginning of labor pain. During cesarean section it was perceived that placenta was completely located in lower segment of uterus from anterior to posterior wall and fundal height was about 10th week of pregnancy. Hysterectomy was performed because of profuse and uncontrollable bleeding. After two weeks، the patient was discharged without any complications. The pathology report revealed complete implantation of placenta into the cervical canal (cervical pregnancy).

The most gestational age of cervical pregnancy which was reported was 14 weeks، while our patient was the first case that her pregnancy continued to 37 weeks. According to the history and performed sonographies، placenta previa was diagnosed for our patient. So، it is strongly recommended that all pregnant women who experience vaginal bleeding and placenta previa is reported in their ultrasound، they should be evaluated regarding cervical pregnancy through three-dimensional sonography and MRI.

Introduction & Placenta previa is one of the main causes of vaginal bleeding at the late phase of pregnancy. Many studies report that Placenta previa causes low weight at the birth (LBW) and intra-uterine growth restriction (IUGR). Therefore، it increases neonatal mortality rate. This study was performed to estimate the relative frequency of placenta previa and its association with LBW and preterm delivery at Rasht al-Zahra hospital during 5 years. This is a descriptive study and was conducted at this hospital by using of patients files of those who had delivery in hospital from 2001-2006. Placenta previa was diagnosed before delivery. The collected data included neonatal weight، maternal age، gestational age، parity، history of previous cesarean and abortion، IUGR and preterm delivery. Of the total 32866 delivery، 79 cases of Placenta previa were observed، of which 29. 1% had LBW. 79. 1% of mothers were between 20 - 34 years old. 45% had parity one، 12. 7% had a previous cesarean and 22. 8% had abortion. The relative frequency of preterm delivery was 40. 5 % and 8. 9% had IUGR. The most frequent case of Placenta previa was found in 30-34 years old group. In this study، the relative frequency of LBW and preterm delivery in placenta previa were more than other studies.

Placenta previa (PP) is a common cause of pri-partum bleeding leading to high mortality and morbidity in mothers and neonates. This study was conducted to determine risk factors and outcomes of PP in Golestan province of Iran.

This case-control study was done on pregnant women admitted for deliverly to the Dezyani hospital of Gorgan, Iran during 2002-07. All PP cases were recruited as case group and 251 non-PP ones were entered into the study as control group. Student t-test and Chi-Square test were used to assess the relationship between variables.

In this study out of 33473 pregnant cases, 82 women (0.24%) had PP. The mean (±SD) age of mothers with PP was 28.5 (±6.2) years. There was a significant correlation between PP and delivery method (P<0.05). History of cesarean section was significantly higher in cases than controls (P<0.05). The prevalence of hysterectomy due to PP was significantly higher in women with history of cesarean section (24%) than other ones (5%) (P<0.05).

We found a significant relationship between history of cesarean section and hysterectomy due to PP. Therefore, PP should be considered in women with a history of cesarean section.

Placenta increta is an uncommon and life-threatening pregnancy complication. This disorder usually is presented with vaginal bleeding during difficult placental removal in the third trimester of pregnancy. However, the disorder may cause some other complications such as abortion at the first or second trimesters of pregnancy too, which make its diagnosis more difficult. This report discusses a case of hysterectomy due to placenta increta at the first trimester of pregnancy.

A 34-years old woman was admitted to Imam Reza Hospital in Mashad, with a history of severe vaginal bleeding. Evacuation curettage had been done due to incomplete abortion at her first admission in another hospital 18 days ago. She had a history of two previous cesarean sections too. Curettage was done to control the severe hemorrhage with a probable diagnosis of incomplete uterine evacuation. Since hemorrhage was not controllable, the patient was consulted for hysterectomy. Afterwards, the pathology report confined the diagnosis, reading “Lower uterine segment with placenta increta”.

Women with a history of previous caesarean sections are at risk for abnormal placentation. The condition is prone to complications such as uncontrollable vaginal bleeding in the first trimester which might necessitate immediate hysterectomy because of the complications due to abnormal nature of placenta increta.

Vaginal bleeding is a tragedy that causes a high mortality and morbidity rate. The aim of this study was to find the most frequent causes of vaginal bleeding in first half of pregnancy.

This study is a cross sectional study performed on 161 cases with vaginal bleeding during pregnancy who had been referred to Taleghani Hospital. Sampling was achieved using non random convenient technique.

The mean age of subjects was 27.1±6.1 years and the mean gestational age was 16.3±10.1 weeks. Mean of gravidity was 2.5±1.6. Thirty three percents of subjects were primigravid. The most common causes of bleeding were: abortion (72.7%), placenta previa (12.4%), ectopic pregnancy (8.1%), and placenta abruptio (6.8%).

Of 161 cases, 75 (46.5%) lead to abortion or curettage. Abortion was by far the most common cause of vaginal bleeding

Abdominal sonography is a best method to defined implantation site of placenta. Determination of placental site is very important if the aggressive method is to be used this study design to define implantation site of placenta in 1585 pregnant women whom referred 28 wk to sonographic center to Deziani Hospital in their third trimester with routine prenatal care. Collection of data perform in nine month and the data was collected by interviewing the pregnant women using a checklist and questionnaire. The results from this investigation show that 51.79% of placenta located in fondoanterior 31.23% fondoposterior, 12.11% posterior another in lateral position and 0.18% of placenta was previa.
