Background: For the growth and development of the unborn child, amniotic fluid is absolutely necessary. Strong interactions between the fetus, placenta, and parts of the mother are given their volume1. Oligohydramnios is defined as having an amniotic fluid index (AFI) <5th percentile or AFI 5 cm during pregnancy and no water at a depth of 23 cm before the cornea. This is a common problem that occurs in 35% of pregnancies during childbirth2. Aim: To determining the correlation between oligohydramnios in pregnant women who are late in pregnancy (3rd trimester) and adverse birth outcomes such as partial surgery, decreased Apgar score, and lower birth weight. Study design: Cohort study Study set up: Obstetrics and Gynecology Department, Fatima Memorial Hospital Lahore. Study period: six months starting15-01-2022 to 14-07-2022 Methods: 242 females were enrolled. Two groups of participants were created: group II had normal AFI and group I had oligohydramnios. Females given intra venous fluids to group I after ruling out any contra indication. The perinatal result was then documented. SPSS version 20 was used to enter and evaluate all of the gathered data. Results: In exposed group the mean age was 27.79±6.72 years, whereas in unexposed group the mean age was 28.25±6.77 years. The C-section was done in 124(51.2%) females. RR = 0.693 [1.25-3.49] While the Low Birth Weight and poor APGAR score has shown protective effect. Practical implication: Oligohydramniosmeans decreased amniotic fluid around the fetus. There is deficiency of amniotic fluid < 200 ml at a time. Approximately 8-10% of pregnant ladies may have decreased level of amniotic fluid but 5% have been confirmed diagnosis of oligohydramnios. Conclusion: So complications of surgery are directly related to the severity of oligohydramnios in pregnant women while low birth weight and poor APGAR scores has shown protective effect in women presented in last trimester of pregnancy.

Introduction: Group B streptococci (GBS) is usually present in a vaginal canal in micro-flora, which usually do not exhibit any symptoms. Instead, in pregnancy, there are certain situations in GBS colonization in the vagina, which may lead to several complications. Objective: To determine the frequency of Group B Streptococcal colonization of the vagina in women at 35-37 weeks of pregnancy.Study Design: Cross-sectional surveySetting: Antenatal clinic, Shalamar Hospital Lahore Study duration: 6 month i.e. From: 05-09-2014 to 06-03-2015Materials and Methods: 350 Booked Patients attending antenatal clinic at Shalamar hospital at 35-37 weeks of pregnancy for routine antenatal checkups were included. Lower vaginal swabs were taken without speculum using sterilized disposable cotton swab and transported to Amies Agar jell and transported to microbiology lab within 24 hours. Laboratory report was collected and reviewed by researcher regarding positive or negative culture for GBS. Patients with positive GBS culture were given intrapartum antibiotics. Results: In our study, out of 350 cases, with the mean age of 26.92+4.84 years. Frequency of GBS colonization of vagina in women at 35-37 week pregnancy was recorded in 12.29% while remaining 87.71% had no findings of the morbidity. Conclusion: It was concluded that the frequency of GBS colonization of vagina in women at 35-37 week of pregnancy is not very higher.
