    Do teenager prefer contraception or termination?
    (Sri Lanka College of Obstetricians and Gynaecologists, 2007) Herath, H.M.R.P.; Dias, T.D.; Amarasinghe, W.L.
    INTRODUCTION: Teenage pregnancy is universal in all known societies past and present. One in four girls in the world becomes a mother before the age of 19 years. In Sri Lanka, 22.2% of maternal deaths due to illegal abortions were in this age group during 1996. Lack of knowledge regarding contraceptive methods is thought to be the main reason for not practicing proper contraception. On the other hand information about domestic violence in families with teenage mother is scares. OBJECTIVES: To describe the use of contraception, attempted pregnancy terminations and violence against women during the pregnancy among teenage mothers delivered at Teaching Hospital Peradeniya. METHOD: A prospective descriptive study was done on teenage mothers who delivered at teaching hospital Peradeniya from 1st of April 2005 to 31st of March, 2006, using interviewer administered questionnaire. RESULTS: There were 190 teenage mothers delivered during the study period. Data was collected from 186 of them. Among these teenage mothers Only 3(1.6%) has studied above GCE ordinary level. Only 28% ofwomen of the group have used any form of contraception, and of which 64% has used barrier methods of contraception. 80 (43%) of teenage mothers had thought of future contraception before they were discharged from the hospital. Termination of the pregnancy has been attempted by 9.1% of the study population. Of those who had'attempted termination 82.4% had not used any form of contraception. Male partners have assaulted 16.1% of teenage mothers during the pregnancy. CONCLUSION: The teenage pregnant mothers have poor educational background. The contraceptive use in the population was very low leading to unnecessary pregnancies and termination of pregnancies. Domestic violence in this population is fairly common.

    Precision of predicting expected date of delivery by ultrasound scan in comparison to last menstrual period
    (Sri Lanka College of Obstetricians & Gynaecologists, 2014) Wasalathilaka, C.; Kumari, S.D.T.L.; Palihawadana, T.S.; Herath, H.M.R.P.; Padumadasa, S.; Pathmeswaran, A.; Dias, T.D.
    INTRODUCTION: Estimation of the expected date of delivery (EDD)is important in management of pregnancy, as many clinical decisions would rely on the estimated gestation of the fetus. In routine clinical practice, this is done by either adding the duration of a pregnancy to the last menstrual period (LMP) or by assessment of fetal biometry by an early pregnancy ultrasound scan (USS). The accuracy of these methods can be assessed either by correlating the dates with people with a know date of conception, such as following IVF, or by study of the correlation with the date of delivery in a cohort of women who goes in to spontaneous labour. In this study we have assessed the accuracy of the two methods by the latter approach. The aim of this study was to assess the agreement of EDD calculated by LMP or USS, to the date of delivery in spontaneous labour. METHODS: This was a retrospective cohort study. 675 patients who had a spontaneous onset of labour were included in the analysis. USS fetal crown rump length was considered for gestational age assessment between 8 and 14 weeks and fetal head circumference considered thereafter. Their agreement of the date of delivery with the estimated expected date of delivery by LMP or USS was assessed. RESULTS: Spontaneous delivery was seen with 6 days of the USS EDD and 7 days of the LMP EDD in 50% of women and within 11days of USS EDD and 15days of LMP EDD among 75% of women. A delivery within 14 date of the EDD was observed in 93.7% when USS EDD was considered and it was only in 86.2% with the LMP EDD (OR 2.40, 95%CI 1.64-3.52). CONCLUSION: This study demonstrate that the USS EDD is more in agreement with the date of spontaneous delivery than the EDD estimated from LMP. This highlights the importance of dating USS in all pregnancies which would be helpful in management of pregnancy in late stages.
