Item Shoulder dystocia.(Sri Lanka college of Obstetricians & Gynaecologists, 2021) Padumadasa, S.; Wijesinghe, P.S.No abstract availableItem Management of anaemia in pregnancy: experience from a Sri Lankan tertiary hospital unit(Wiley-Blackwell, 2015) Palihawadana, T.; Dias, T.; Motha, C.; Thulya, S.D.; Herath, R.; Wijesinghe, P.S.INTRODUCTION: Higher rates of pregnancy complications have been reported among anaemic pregnant women. Universal iron supplementation during pregnancy is recommended in countries where iron deficiency anaemia (IDA) prevalence rates are high. Sri Lanka also carries out a policy of such supplementation. The effectiveness of such programmes in different settings is variable. A retrospective analysis of the effectiveness of our current policy on prevention and treatment of anaemia was done for programme evaluation. METHODS: The North Colombo Obstetric Database (NORCOD) was used retrospectively to analyse the data between March and August 2014, at the university obstetric unit of the North Colombo Teaching Hospital, Sri Lanka. All singleton pregnancies without medical comorbidities were included in the analysis. Those who did not have haemoglobin (Hb) recording in the first trimester or in the third trimester were excluded at the data cleaning stage. An Hb level of <11 g/dL and a level of <10.5 g/dL were considered as anaemia in first and third trimesters respectively. The prevalence of anaemia at booking, and the Hb status in the third trimester were assessed. RESULTS: A total of 1340 singleton pregnancies were included in the analysis and 74 were excluded from the analysis due to incomplete data. 28.9% (n = 366) were found to be anaemic at booking while 63.9% (n = 809) were with a normal Hb and 7.1% (n = 91) were with an Hb of >13 g/dL. In the third trimester the prevalence of anaemia was 11.5% (n = 146) while 64.7% (n = 820) were with normal Hb and 23.6% (n = 300) were with an Hb of >13 g/dL. Among the anaemic women at booking, 22% (n = 81) persisted to be anaemic in the third trimester while 65% (n = 238) became normal and 12.8% (n = 47) developed a higher Hb level. Among those with a high Hb at booking only 1% became anaemic by third trimester while 40.6% persisted to have a high Hb level. CONCLUSION The prevalence of anaemia in this population was of moderate severity (>20% but <40%) as defined by the WHO. Major shortcoming in our practice is that we were unable to successfully treat nearly quarter of women who present with anaemia at booking, thus highlighting sub-optimal treatment. Furthermore, a policy of universal supplementation seems to over treat women with a high Hb at booking. Therefore, a more individualised supplementation and treatment policy should be encouraged in routine clinical practice.Item The new normal of medical education - challenges and opportunities(South East Asia Regional Association for Medical Education (SEARAME), 2020) Karunathilake, I.M.; Dissanayake, V.H.W.; Yasawardena, S.; Abegunawardena, A.; Raviraj, S.; Wijesinghe, P.S.; Anthony, A.A.; Wijesinghe, R.A.N.K.; Bowatte, S.; Wickramaratne, N.; Pathirana, K.D.; Pilapitiya, S.; Edirisinghe, S.; Hettiarachchi, D.; Kohombange, C.; Olipeliyawa, A.No abstract availableItem Zinc supplementation in chronic kidney disease of unknown aetiology in Sri Lanka: a pilot study. (ZisCKDu-P)(Ceylon College of Physicians, 2020) Abeysundara, P.K.; Nishad, N.; de Silva, S.T.; Dassanayake, R.T.; Galabada, D.P.; Jayawardane, U.G.W.; Premawardana, N.P.; Kumara, G.M.S.S.; Dilani, P.M.; Herath, H.M.T.D.; Wijesinghe, P.S.INTRODUCTION: It was hypothesized that the antioxidant properties of zinc retard the progression of chronic kidney disease of unknown etiology in the North Central Province of Sri Lanka. METHODS: The pilot study was a randomized, placebo-controlled, single blinded, parallel group, single-center clinical trial with two arms (Z and P) and a 1:1 allocation ratio. Participants in group Z (n=20) received 60 mg of elemental zinc daily, in the form of zinc sulfate, and group P (n=21) received a starch tablet per day. Clinical, hematological parameters and kidney function were measured at the baseline and following three months of the intervention. RESULTS: A total of 86 CKDu patients were screened; only 35 males and 6 females were selected. Mean age and estimated glomerular filtration rate of the study population were 51.2±6.2 years and 38.9±8.8 mL/min/1.73 m2 respectively. At the end of three months there was non-significant increase in urine protein creatinine ratio (Z arm: 65±54 vs. 82± 86 mg/mmol; P=0.46, P arm: 72.4±113 vs. 120± 209 mg/mmol; P=0.36) and non-significant decline in estimated glomerular filtration rate (Z arm: 40.9±10.4 vs. 39.7±9.2 mL/min/1.73 m2; P=0.31, P arm: 37.1±6.8 vs. 36.4±10 mL/min/1.73m2; P=0.31) in both groups. Body mass index was significantly reduced (23±4 vs. 22.7± 3.9 kg/m2; P=0.01) and diastolic blood pressure was significantly increased (78±6 vs. 86±10 mmHg; P=0.001) in the placebo arm. Haemoglobin levelshowed a decline in the study group; 0.33±1 g/dl, while there was an increase in the placebo group, 0.34±0.7 g/dl, (P=0.02). There were no major side effects. CONCLUSIONS: The change of urine protein: creatinine ratio and estimated glomerular filtration rate did not show a significant difference between the two groups. A future trial should test effectiveness of same dose of zinc for a similar duration of time in a larger sample. Extended follow-up of the study subjects for one year after the intervention would be useful to assess the long-term effects of zinc on kidney function and side effects.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 Nonpuerperal uterine inversion: What the gynaecologists need to know?(Hindawi Pub. Corp., 2020) Herath, R.P.; Patabendige, M.; Rashid, M.; Wijesinghe, P.S.INTRODUCTION: Nonpuerperal uterine inversion (NPUI) is a rare clinical problem with diagnostic and surgical challenges. The objective of our study was to review the literature on NPUI and describe causative pathologies, diagnosis, and different surgical options available for treatment. MATERIALS AND METHODS: A comprehensive literature review was carried out on MEDLINE and Google Scholar databases to look for NPUI using the term "non-puerperal uterine inversion," and further went through the cross-references of the published articles. Data are published case reports from 1911 to September 2018. Of the 153 published cases, 133 reports had adequate details of surgery for analysis. These reports were analyzed, concerning the clinical presentation, methods of diagnosis, and surgical treatment. RESULTS: Mean age of the women was 46.3 years (standard deviation: 18, N = 153). Leiomyoma remained the commonest (56.2%) aetiology. While malignancies contributed to 32.02% of cases, 9.2% were idiopathic. High degree of clinical suspicion and identification of unique features on ultrasonography and magnetic resonance imaging enable prompt diagnosis. In cases of uncertainty, laparoscopy or biopsy of the mass was used to confirm the diagnosis. Hysterectomy or repositioning and repair of the uterus are the only treatment options available. The surgical methods implemented were analyzed in three aspects: route of surgical access, method of repositioning, and final surgical procedure undertaken. The majority (48.8%) had only abdominal access, while 27.1% had both abdominal and vaginal access. Haultain procedure was the most useful procedure for reposition (18.0%) of the uterus. The majority (39.7%) required abdominal hysterectomy with or without debulking of the tumour abdominally, while 15.0% had uterine repair after repositioning. We reviewed the different surgical techniques and described and proposed a treatment algorithm. CONCLUSIONS: Fibroids were the commonest cause for NPUI. Malignancies accounted for one-third of cases. A combined abdominal and vaginal approach, followed by hysterectomy or repair after repositioning, seems to be better for nonmalignant cases.Item National Maternal Death surveillance and Response: Sri Lankan scenario(Sri Lanka Medical Association, 2019) Wijesinghe, P.S.; Jayaratne, K.; Peiris, D.No abstract availableItem A Case report of Meningioma with uncal herniation in pregnancy(Sri Lanka College of Obstetricians & Gynaecologists, 2017) Suthakaran, V.; Perera, M.N.I.; Herath, H.M.R.P.; Dias, T.D.; Wijesinghe, P.S.INTRODUCTION: The diagnosis and management of meningioma during pregnancy is a challenge, with growth and regression both reported. The occurrence of meningioma during pregnancy is rare, comparable with that in non-pregnant woman in the same age group. We report a case of meningioma with uncal herniation leading to maternal death during pregnancy. CASE: Thirty-year-old woman was referred to our unit on her 20th weeks of gestation for severe headache and vomiting. This is her third pregnancy with two living children, both delivered by caesarean section. She had early morning headache, lasting for 1 to 2 hours which resolved following vomiting from16th week of gestation. She did not have visual impairment, photophobia or focal neurological ymptoms. She was admitted to base hospital for increased frequency and severity of headache on her 18th week of gestation. Neurological examination was normal. Her blood pressure was normal throughout this pregnancy. She defaulted herneurology appointment. She was readmitted for same symptoms and transferred to our hospital. She complained severe headache, vomiting and blurred vision on day of admission followed by difficulty in breathing. Her SPO was 84 % on air and respiratory rate was 32/minutes. Ophthalmoscopy was normal. She was intubated for impending respiratory arrest and non-contrast CT was performed. CT showed Right sided sphenoidal wing tumour suggestive of a meningioma with midline shift and uncal herniation. She developed repeated episodes of a systole before transfer to neurosurgical unit and did not recover. Postmortem findings and histology confirmed the diagnosis of meningothelial type of meningioma. DISCUSSION: Intracranial tumours in pregnant woman are serious and life threatening conditions. The clinical presentation of intracranial mass mimics the symptoms of hyperemesis gravidarum, eclampsia and puerperal psychosis. MRI of the brain is the investigation of choice for prompt diagnosis of meningioma. Surgery is the key in the management of meningioma depend on the site of tumour. The general recommendation in pregnancy is for caesarean section as first surgery followed by neurosurgical interventions. Urgent neurosurgical linterventions are indicated for patients with malignant tumours, active hydrocephalus or benign tumours with impending herniation or progressive neurological deficits.Item Cut-off Scores for International Consultation on Incontinence Modular Questionnaire on Vaginal Symptoms (ICIQ-VS) in Sinhala and Tamil(Sri Lanka College of Obstetricians & Gynaecologists, 2017) Amarasekara, A.M.A.K.G.; Ekanayake, C.D.; Pathmeswaran, A.; Wijesinghe, P.S.; Liyanage, L.L.C.; Kulasinghe, I.R.M.M.; Perera, H.S.S.INTRODUCTION: It is clinically beneficial to have cut-off scores for screening questionnaires, above which a patient can be referred for further evaluation at a specialist center especially in developing countries. OBJECTIVE: To calculate cut off scores for ICIQ-VS-Sinhala and ICIQ-VS- Tamil questionnaires. METHODS: The ICIQ-VS- Sinhala and ICIQ-VS-Tamil was administered to women attending the gynaecology clinics at North Colombo teaching hospital, Ragama, District General hospitals, Mannar and Vavuniya. The vaginal symptoms score (VSS), sexual symptoms score (SSS) and the quality of life score (QoL) were analysed against the clinician’s diagnosis of significant prolapse using receiver operating characteristic curves (ROC). Results: The AUC (area under curve) for ROC curves of VSS, SSS and QoL for ICIQ-VS-Sinhala were 0.89 (p<0.001), 0.64 (p<0.02) and 0.75 (p<0.001) respectively. The AUC for ROC curves VSS, SSS and QoL of ICIQ-VS-Tamil were 0.88 (p<0.001), 0.70 (p<0.02) and 0.82 (p<0.001) respectively. The optimal MCIDs for ICIQ-VS-Sinhala were VSS ≥≥ 8 (sensitivity 88.1%, specificity 73.9%), SSS ≥ 1 (sensitivity 59%, specificity 65%), QoL ≥ 3 (sensitivity 77.8%, specificity 60.4%) while for ICIQ-VS-Tamil VSS ≥ 9 (sensitivity 87.1%, specificity 80.9%), SSS ≥ 1 (sensitivity 76.5%, specificity 61.1%) and QoL ≥3 (sensitivity 77.8%, specificity 79.8%). CONCLUSION: Both questionnaires yielded promising cut off scores for VSS, SSS and QoL. Cut-off scores of VSS ≥9, SSS ≥1 and QoL≥3 for ICIQ-VS-Tamil and VSS ≥8, SSS ≥1 and QoL ≥3 for ICIQ-VS-Sinhala can be used as a guide for specialist referral when using ICIQ-VS to screen for pelvic floor dysfunction in Sri Lanka.Item First episode of genital herpes simplex virus infection in the third trimester of Pregnancy; diagnostic limitations and effects on mode of delivery: a case study(Sri Lanka College of Obstetricians & Gynaecologists, 2017) Pannala, W.S.; Ranatunga, J.D.; Wijesinghe, P.S.BACKGROUND: Risk of herpes simplex viral (HSV) transmission to the baby during vaginal delivery following maternal primary genital herpes in the third trimester is 41%. Caesarean section is recommended in such instances to minimize the risk of neonatal herpes.DNA-PCR is the gold standard of diagnosis of HSV infection. Crossreactivity of HSV1 and HSV2 IgM, variable IgM response in relation to time make these tests less useful. Furthermore, raised IgM may not always indicate primary infection. DNA-PCR does not differentiate primary infection from a recurrence which has lower risk of neonatal herpes (0- 3%). IgG has a lower positive predictive value in low prevalence settings. CASE: A 19-year-old primigravida at 36 weeks presented with four days’ history of dysuria, multiple painful superficial genital ulcerson both labia with painful bilateral inguinal nodes. Neither she nor her partner had genital or oral lesions before. Syphilis serology, dark ground examination and HIV antibody test were negative whereas Tzanck smear was positive. Clinical diagnosis of primary HSV infection was made and she was treated with acyclovir which was continued until five days after delivery. Two weeks later, she was positive for HSV1+HSV2 IgM antibody ELISA, and negative for type common IgG. Elective LSCS resulted in a healthy baby weighing 3.02kg. Serology four days later had a slightly higher IgG index than previous assay. CONCLUSION: High risk of neonatal herpes following primary genital herpes during third trimester, inability to differentiate primary infection from recurrence by available investigations, and practical difficulties of performing these investigations, necessitate management decisions to be based on clinical diagnosis in resource limited settings.
