Item Post-placental and interval intrauterine contraceptive device (IUD) insertion: does timing matter?(Wiley-Blackwell, 2015) Dias, T.D.; Palihawadana, T.S.; Wijekoon, D.; Ganeshamoorthy, P.; Abeykoon, S.; Liyanage, G.; Padeniya, T.INTRODUCTION Unintended pregnancies in the first year after childbirth could be high as 10–44% and expose women to consequences of induced abortion, especially in countries where termination of pregnancy is illegal. Immediate postpartum contraception methods are beneficial for women who wish for early contraception and for women who have difficulty in returning for postpartum visits for contraception. Use of Copper containing intrauterine contraceptive device (IUD) immediately after delivery (post placental) has been described recently with varying success. The aim of this study was to compare the rate of spontaneous expulsion and intrauterine displacement between post placental IUD insertion and routine IUD insertion, 6 weeks after delivery. METHODS This was an interventional comparative study. Women who were willing to start on IUD as a contraceptive method after childbirth were recruited for the study. They were randomly allocated to either group before labour/ delivery and those in the group of post placental insertion had it inserted immediately following vaginal delivery and those allocated for interval group had insertion 6 weeks after delivery. Two ultrasound examinations were performed, just after the insertion and 6 weeks later in both groups. The distance from the IUD to the internal os was measured at each examination to evaluate the displacement. RESULTS The study included 30 subjects in the post placental group and 33 in interval insertion group. The postpartum insertion group and the interval insertion groups were comparable for age [mean (SD) 27.1 (5.42) versus 25.6 (4.34), P = 0.23] and BMI [mean (SD) 22.4 (7.28) versus 23.9 (5.76), P = 0.34]. As expected, the uterine length at insertion was higher among the post placental group [mean (SD) 144.1 mm (12.2) versus 66.8 (6.7), 95%CI 72.3 to 82.1] but similar in two groups at follow up [66.6 mm (15.1) versus 64.79 (6.64), 95%CI _4.01 to 7.47]. Spontaneous expulsion and displacement was not significantly different between the post placental and interval insertion groups [3/30 versus 2/33, OR 1.72; 95%CI 0.28 to 10.7]. In these two groups, there was no difference noted in the second ultrasound measurements from the IUD to the fundal wall [16.9 mm (3.99) versus 18.24 (4.36); 95%CI _3.45 to 0.77] or to the internal os [21.8 mm (15.7) versus 17.1 (6.03); 95%CI _1.12 to 10.6]. CONCLUSION This study demonstrates that insertion of an IUD immediately after delivery does not increase the risk of spontaneous expulsion or the risk of downward displacement. Therefore, such insertion can be recommended in clinical practiceItem Seizure patterns, preconception care and pregnancy outcomes in women with epilepsy in a tertiary care hospital(Journal of the Ceylon College of Physicians, 2020) Motha, M.B.C.; Palihawadana, T.S.; Jayasinghe, C.; Ranawaka, U.K.INTRODUCTION AND OBJECTIVES: Data on epilepsy in pregnancy is limited from South Asia and other resource-limited countries. We sought to describe seizure patterns, preconception care and pregnancy outcomes in women with epilepsy attending a Sri Lankan tertiary care hospital. METHOD: All pregnant women with epilepsy admitted to University Obstetrics Unit, Colombo North Teaching Hospital during the period January 2017 February 2020 were recruited. Data were collected by a single physician using an interviewer-administered questionnaire. RESULTS: Out of 9520 pregnant women screened, 63 had a history of epilepsy (prevalence 6.6/1000); 46% generalized epilepsy, 22.2% focal epilepsy. Of 38 women on antiepileptics at conception, only 44.7% were given folic acid 5 mg preconceptionally. 42.9% were seizure free over preceding 2 years. Majority (55%) had a seizure during current pregnancy (average number of seizures per patient: 1s1 trimester 1.85, 2nd trimester 2.2, 3rd trimester 2.95, postpartum 2.5). 18.4% of seizure events were attributed to sleep deprivation, and 2.7% to unsatisfactory drug compliance. 81.6% were on monotherapy at conception and 18.4% were on two antiepileptic. 22.2% had a hypertensive disorder of pregnancy and 9.5% spontaneous premature delivery. 33.3% underwent caesarian delivery. 1.58% each had a stillbirth and neonatal death. Low birth weight was seen in 42.9%. Major congenital malformations were found in 11.1% of newborns. CONCLUSIONS: Pre-conceptional folic acid coverage was poor. Seizures occurred in more than half of the women and were more common in third trimester and postpartum. Rates of hypertensive disorders, caesarean deliveries, low birth weight and congenital malformations were high.Item Childbirth Experience Questionnaire (CEQ) in the Sri Lankan setting: translation, cultural adaptation and validation into the Sinhala language(BioMed Central, 2020) Patabendige, M.; Palihawadana, T.S.; Herath, R.P.; Wijesinghe, P.S.OBJECTIVE: To adapt the CEQ into Sri Lankan Sinhala cultural context and to determine the psychometric properties of CEQ. This would yield an opportunity to evaluate childbirth experience among Lankan population. RESULTS: Out of 390, 226 (57.9%) postnatal mothers completed the CEQ after 1 month postpartum. Face validity and content validity were demonstrated with all participants stating that CEQ was easy to understand and complete. For reliability, internal consistency was acceptable for the overall score (0.85) and for all four domains in CEQ (0.65, 0.80, 0.70, 0.83 for "own capacity", "professional support", "perceived safety" and "participation", respectively). A weighted kappa of 0.61-0.80 for all 22 items in CEQ demonstrated a good test-retest reliability. This Sri Lankan version showed fit statistics in line with standard recommendations in exploratory factor analysis. Women with spontaneous onset of labour (except for "professional support" in women with spontaneous onset of labour) and women with a normal birth showed significantly higher CEQ scores. However, oxytocin augmentation could not yield a difference in CEQ scores. KEYWORDS: Birth satisfaction; Childbirth experience questionnaire; Low-resource settings.Item Ultrasound parameters of pelvic organs and their age-related changes in a cohort of asymptomatic postmenopausal women: A community-based study.(Sage Publishing, 2020) Dias, T.D.; Palihawadana, T.S.; Patabendige, M.; Motha, M.B.; de Silva, H.J.No abstract available.Item Prevalence of menopausal symptoms and their impact on daily activities: A community based longitudinal study in Ragama, Sri Lanka(Sri Lanka College of Obstetricians & Gynaecologists, 2016) Heenatigala, C.S.N.; Gunathilaka, S.N.M.P.K.; Dias, T.D.; Palihawadana, T.S.; Motha, M.B.C.; de Silva, H.J.OBJECTIVES: To determine the prevalence and severity of menopausal symptoms among women. DESIGN,SETTING AND METHODS: A community-based cross sectional study was done in a study population of a larger ongoing longitudinal study named ‘Ragama Health Study’. Randomly selected 954 women from Ragama Medical Officer of Health (MOH) area were included. Data was collected using a self-administered questionnaire. Impact on daily activities by menopausal symptoms were scored using a scale from 1-10.RESULTS: Out of 954 women in the study, 814(85.3%) were postmenopausal. Age of the population distributed from 41-74 years with mean of 59.51 years. Mean age of onset of the menopausal symptoms was 52.16(SD=8.095) years. Among the symptoms inquired, the domain of sexual activity contained the most commonly experienced symptom, decreased libido, with a 65.4% (n=937) positive responses while 20.5% of women experienced vaginal dryness.. Mean score on impact on daily activities by this was 7.79(SD 2.36). Psychosocial symptoms of forgetfulness, bad temper, irritability and poor concentration was present in 60.5%, 33.8%, 25.4% and 24.8% of positive responses respectively. Mean scores on impact on daily activities by psychosocial symptoms lied within the range of 4.55-5.52. Presence of experiencing hot flushes and increased sweating were 24.8% and 22.1% with a mean score of effect on daily activities at 5.24 and 5.65, respectively. CONCLUSIONS The rate of menopausal symptoms among this perimenopausal age group was significant and the impact on daily activities in this population was comparable to the global contextItem A study on the rate of symptoms of pelvic floor dysfunction among healthy women in pre and post-menopausal age and its impact on their day-to-day life.(Sri Lanka College of Obstetricians & Gynaecologists, 2016) Pieris, K.V.M.; Prasanga, D.P.G.G.M.; Dias, T.D.; Palihawadana, T.S.; Motha, M. .C.; de Silva, H.J.OBJECTIVES: Aim of the study was to analyze the rate of symptoms of pelvic floor dysfunction, the presence of pelvic organ prolapse and to study how the symptoms affect the day to day life activities in a population of women living in the Ragama Medical Officer of Health (MOH) area.DESIGN, SETTING AND METHODS: A community-based cross sectional study was done in a study population of a larger ongoing longitudinal study named ‘Ragama Health Study’. Randomly selected 951 women from Ragama Medical Officer of Health (MOH) area were included. The symptoms of pelvic floor dysfunction were elicited using a self-administered questionnaire and a vaginal examination was performed to assess the presence and grade of pelvic organ prolapse. RESULTS: Among the 951 women 881(92.6%) did not have symptoms of pelvic floor dysfunction. Among the symptomatic women (n=70), urgency was the commonest symptom (26.8%) while 23.5% admitted urinary incontinence and 16.1% of women experienced fecal incontinence. Among the women with such symptoms of pelvic organ prolapse only 5.6% complained of these interfering with their sexual activities while 10.8% admitted them having an effect on their day-to-day activities. Pelvic organ prolapse was not elicited on clinical examination in 32.1% of symptomatic women while 60.7% had a prolapse up to the hymen and 7.2% had a prolapse beyond the level of hymen. CONCLUSIONS: Rate of symptoms of pelvic floor dysfunction was around 7.5% among this sample of women in peri and postmenopausal age. Urinary incontinence and fecal incontinence were the most frequent symptoms. Only a few symptomatic women considered this to have an effect on their sexual function (5%) and day-to-day activities (10%). More than two thirds of women with symptoms had genital prolapse with over 7% having a significant prolapse protruding beyond the hymen.Item Metabolic syndrome and risk of endometrial carcinoma among asymptomatic, postmenopausal, urban Sri Lankan females: a community cohort follow-up study(Wiley Publishing, 2017) Dias, T.; Niriella, M.; de Silva, S.; Motha, C.; Palihawadana, T.S.; Ediriweera, D.; de Silva, J.OBJECTIVES: Metabolic syndrome (MetS) has been recognised as a risk factor for malignancies. The aim of this study was to evaluate the association of MetS and risk of endometrial carcinoma (EC), by measuring endometrial thickness (ET). METHODS: The Ragama Health Study (RHS) recruited 35-64-year-old female cohort by age-stratified random sampling in 2007 and re-evaluated them in 2014, using a structured interview, anthropometric measurements and biochemical tests. Liver ultrasound to detect fatty liver was performed in 2007. Pelvic ultrasound to detect ET was performed in 2014 among consenting participants. MetS was diagnosed on established International Diabetes Federation (IDF 2012) criteria. Increased ET was defined as >5mm. Simple logistic regression was used to screen variables and multiple logistic regression was used to obtain adjusted effects of risk factors for increased ET. RESULTS: 813/1636(49.7%) of the original female cohort attended follow-up; ET was measured in 567(69.7%). Median (IQR) age of females was 61 (56-66) years. 323 fulfilled criteria for MetS (prevalence 57.1%) in 2007. 57(10.1%) had increased ET in 2014. Increasing plasma triglycerides [OR=1.004 per mg/dl, 95%CI:1.001-1.007, p<0.05] and being hypertensive [OR=2.16, 95%CI:1.11–4.08, p<0.05] were associated with increased ET, while advancing age [OR=0.93 per year, 95%CI:0.89–0.98, p<0.01] and being diabetic [OR= 0.34, 95%CI:0.10–0.89, p<0.05] were protective. CONCLUSIONS: Hypertension and increased plasma triglyceride levels, in the pre-menopausal period, were risk factors for future asymptomatic increased ET.Item Study on age-ralated variation in ovarian volume and proportion of endometrial thickness abnormalities in women of advanced and post-reproductive age(Wiley Publishing, 2016) Pieris, V.; Dias, T.; Palihawadana, T.S.; de Silva, J.OBJECTIVES : To describe the variations in endometrial thickness and the ovarian volume among peri and postmenopausal women. METHODS : A cross-sectional analysis was done in a study population of a longitudinal study. This was a community-based study and included 888 women randomly selected from the Ragama, Sri Lanka. This was done as part of a larger ongoing study, the “Ragama Health Study”. All study participants underwent a transvaginal pelvic ultrasound scan and the endometrial thickness and the ovarian size were measured. The ovarian volume was calculated using the formula for a prolate ellipsoid (0.523 h x w x l). RESULTS: The mean age of the study population was 59.45 yrs (SD=7.601) and 85.8% (n = 762) of them had undergone menopause. The prevalence of an endometrial thickness (ET) > 10 mm among premenopausal women was 14.98% while 0.9% (n = 1) had an ET>15 mm. Among postmenopausal women an ET >4 mm was seen in 16.01%. This included 1.3% (n = 10) who had an ET >10 mm. The mean of average ovarian volumes of the study population, according to age is shown in the figure. CONCLUSIONS : The study demonsatrated the proportion of asymptomatic women with a thickened endometrium among perimenoausal and poatmenopausal women (>15 mm and >4 mm resepectively) that necessitate evaluation is around 1%. It also described the age related changes in ovarian volume.Item Nutcracker syndrome in pregnancy: a worrying presentation of a benign condition(Sri Lanka Medical Association, 2017) Motha, M.B.; Palihawadana, T.S.; Dias, T.D.; Wijesinghe, P.S.Item Prevalence of menopausal symptoms and their impact on daily activities: A community based longitudinal study in Ragama, Sri Lanka(Sri Lanka College of Obstetricians & Gynaecologists, 2016) Heenatigala, C.S.N.; Gunathilaka, S.N.M.P.K.; Dias, T.D.; Palihawadana, T.S.; Motha, M.B.C.; de Silva, H.J.OBJECTIVE: To determine the prevalence and severity of menopausal symptoms among women.
