Item 6379 Pre-admission management of children presenting with febrile illness in a tertiary hospital of Sri Lanka(BMJ, 2024) Arunath, V.; Mettananda, S.OBJECTIVES To describe the symptoms and pre-admission management of children presenting with febrile illness to the Colombo North Teaching Hospital, Ragama, Sri Lanka.METHODS A retrospective descriptive study was conducted at University Paediatric Unit of Colombo North Teaching Hospital, Ragama, Sri Lanka. Data on pre-admission management of all children admitted with febrile illness from July to December 2019 were extracted from patient records. Children who were transferred from other units, children with chronic illnesses and children developed fever following vaccinations were excluded. Ethical approval was obtained from Ethics Review Committee of Sri Lanka College of Paediatricians and data was analysed using SPSS version 22.RESULTS A total of 366 children were admitted; 56% were males. Mean age was 53.5 ± 41.7 months and the majority were from Gampaha district. Mean duration of illness on admission was 3.6 ± 2.5 days. 236 (65.6%) patients had recorded fever spikes at home while 150 (60.7%) reported a contact history of fever. Common associated symptoms were cough (62.3%), cold (56%) and vomiting (39.6%). 199 (54.5%) underwent investigations prior to admission and full blood count was the commonest (47.5%) investigation. Although 357 (97.8%) had taken medication prior to admission, only 87.3% had consulted a doctor. 356 (97.3%) received paracetamol at home of which 24 (7.9%) and 123 (40.6%) received sub-therapeutic and supra-therapeutic doses respectively. Significantly higher proportion (44.9%) of children who consulted a doctor received appropriate dose of paracetamol compared to others (3.7%), (c2=11.9, p=0.003, p<001). Higher proportion children who had recorded fever spikes consulted a doctor (c2=3.99, p=0.046, p<0.05) and received therapeutic doses of paracetamol prior to admission (c2=4.94, p=0.026, p<0.05).CONCLUSION Use of sub- and supra-therapeutic doses of paracetamol was common before admission to the hospital. Recording temperature at home and medical consultation prior to admission were associated with appropriate dose paracetamol usage (p<005).Item 6542 Clinical profiles of children less than 5 years presenting with or high risk of cerebral palsy in the Western Province of Sri Lanka(BMJ, 2024) Sumanasena, S.; Heiyanthuduwage, T.M.; Fernando, R.; Sheedy, H.S.; Jagoda, J.; Wijesekara, S.; Wanigasinghe, J.; Muttiah, N.; Rathnayake, P.; Kitnasamy, G.; Khandaker, G.OBJECTIVES Cerebral palsy (CP) is the commonest physical disability in children globally.1 It is a clinical diagnosis based on clinical and neurological findings. International clinical practice guidelines recommend early diagnosis and CP specific interventions to invest in neural plasticity and achieve optimal functional levels.2 In the past diagnosis was confirmed at 12–24 months but now it is advanced to confirm or identify as high risk for CP before the age of six months.3 4 Sri Lanka is one of the few Asian countries that initiated a CP register and National Guidelines on management of CP.5 The objective of this paper is to describe the clinical profiles of children less than 5 years presenting to Western Province hospitals in Sri Lanka based on the data from the Sri Lanka Cerebral Palsy Register (SLCPR).METHODS A cross sectional hospital-based study was conducted in the Western Province from September 2018 – October 2021 in three teaching hospitals to collect a minimum data set for the Sri Lanka SLCPR. Data of children less than 60 months was extracted with a confirmed clinical diagnosis of CP or identified formally as ‘high risk’ of CP.Information on sociodemographic, pre/peri/neonatal, and post neonatal risk factors, and associated impairments were collected using hospital records and clinic notes. Clinical motor type, topography, and associated impairments were evaluated.RESULTS Data of 431 children were extracted, 254 (58.9%) were males. Mean age at diagnosis was 28.73 months (median 27, SD 14.98). Most children (n= 422, 97.9%) acquired CP in the pre/peri/neonatal period. The mean birth weight was 2304.4 g (median 37, SD 825.58g) and the mean POA was 35.82 months (median 37, SD 4.88). Main risk factors identified were prematurity (n=190, 44.1%), hypoxic ischaemic encephalopathy (HIE) (n= 234, 54.3%), jaundice (n=31, 7.2%) and sepsis (n= 13, 3.0%). While 183 children (42.5%) showed evidence of definitive spastic motor type, 184 (42.7%) showed predominant dyskinesia.CONCLUSION The age at diagnosis of this population from Sri Lanka is significantly lower than from other LMICs. HIE and prematurity, both preventable conditions remain the highest risk factors. Longitudinal follow up will ascertain the final motor outcomes as a higher proportion of children showed dyskinesia. The SLCPR is an important resource which will support new research towards investigating opportunities for prevention and service planning for children.Item 6460 Children’s perception of the health effects of climate change – a mixed-method study in urban Sri Lanka(BMJ, 2024) Dayasiri, K.; Anand, G.OBJECTIVES While children bear the least responsibility for global climate change, they suffer the most from its consequences, including a higher incidence of non-communicable diseases and exposure to natural disasters. The United Nations has emphasised that failing to act on climate change infringes upon children’s rights to live in a secure environment. Our study focuses on examining the perspectives of Sri Lankan adolescents on climate change, its effects, and their roles in addressing this issue.METHODS This mixed-method cross-sectional study involved 104 adolescents attending schools in Colombo, Sri Lanka. We randomly selected participants from both governmental and private schools and invited them to complete a self-administered questionnaire. The questionnaire covered their perceptions of climate change, their contributions to addressing climate change, and their views on the regional and global implications of climate change. Qualitative data analysis was conducted using a second-order descriptive analysis of themes.RESULTS 104 adolescents participated in the study and 75.8% were female children. Median age =17 years (range 13–19 years). Majority (93.1%) expressed concern about the potential future health impacts of climate change. While most adolescents correctly understood the concept of climate change, some revealed misconceptions about it. The major health impacts associated with climate change, as reported by the participants, included asthma, the rise of non-communicable diseases, skin conditions, cancer, and increased stress. Notably, 25% of the participants felt that they had not received education on climate change. Nearly 60% reported feeling anxious over the issue of climate change. Regarding their contributions to addressing climate change, 29.8% of the children admitted that they had not taken sufficient actions. However, those who had acted mentioned activities such as tree planting, increased use of public transportation, and educating others about climate change. Almost half of the cohort were unaware of useful resources for learning about climate change. A significant 76% of the adolescents believed that adults were not actively taking measures to address climate change.CONCLUSION This study showed that children are evidently anxious over the issue of climate change. There is an urgent need for improved awareness of information sources among children through public health measures. It is essential for adults including those in the medical profession to serve as role models in educating and guiding children on how to make a positive impact on global climate change.Item OP59 Ultra-processed food consumption in South Asia: quantification of regional variation in intakes and the assessment of their sociodemographic correlates. Findings from the South Asia Biobank in four South Asian countrie(BMJ, 2024) Bhagtani, D.; Adams, J.; Imamura, F.; Lahiri, A.; Irfan, K.; Jha, V.; Kasturiratne, A.; Katulanda, P.; Mridha, M.; Anjana, R.M.BACKGROUND Escalation of ultra-processed foods (UPFs) sales has been recorded in low-to-middle-income countries, including in South Asia. However, individual consumption levels and sociodemographic characteristics influencing UPF consumption remain largely unknown in South Asia. We aimed to quantify UPF consumption and investigate its sociodemographic correlates in South Asia.METHODS We analysed data from 60,714 participants in the South Asia Biobank that recruited adults in Bangladesh, Pakistan, Sri Lanka, North India, and South India. Dietary assessment was conducted using interviewer-led 24h dietary recalls with a South Asia-specific digital tool. Foods were classified by the degree of industrial processing using the NOVA classification. Adjusted two-part multivariable regression models examined associations between sociodemographic factors and any UPF consumption and quantity of UPF consumption in consumers.RESULTS In Bangladesh, Sri Lanka and North India, approximately 75% of the participants reported consuming any UPFs in the previous 24h while in South India and Pakistan this was 40%. Median contribution of UPFs to total energy among UPF consumers ranged between 17% in Pakistan, 15% in North India, and 13% in Bangladesh, Sri Lanka, and South India. Biscuits were a common source of UPF across all regions. Other commonly consumed UPFs among consumers included sweetened beverages in Pakistan, packaged salty snacks in South India, and breakfast cereals in Bangladesh. Diverse associations between sociodemographic factors and any UPF consumption were seen across regions. Younger age was associated with any UPF consumption in Pakistan and Sri Lanka whereas in Bangladesh and North India, older age was. In all regions except Bangladesh, female sex was associated with any UPF consumption. Higher education was associated with UPF consumption in Bangladesh (odds ratio 2.01; 95% confidence interval 1.71 to 2.35), Pakistan (1.69; 1.55 to 1.85), and North India (1.40; 1.13 to 1.73). Paid employment was not associated with UPF consumption in any region. Among UPF consumers, in all regions, UPF consumption was lower in married or cohabitating than in single people. In Bangladesh and Sri Lanka UPF consumption was higher in rural residents, while in Pakistan, consumption was higher in urban participants.CONCLUSION Younger age, female sex, higher education, employment, and income exhibited associations with UPF, but this varied across South Asia. This heterogeneity should be considered when developing regionally specific interventions to support dietary public health. Our findings of regional consumption of specific UPFs, such as biscuits, breakfast cereals, sweetened beverages, and salty snacks, provide valuable insights for targeted interventions.Item 6503 Using anthropometric data to investigate the nutritional status of children included on the Sri Lankan cerebral palsy register.(BMJ Publishing Group Ltd, 2024) Sumanasena, S.; Fernando, R.; Kurukulaarachchi, S.; Heiyanthuduwage, T.M.; Sheedy, H.S.; Wijesekara, S.; Jagoda, J.; Muttiah, N.OBJECTIVES The nutritional data from children with cerebral palsy (CP) in low and middle income countries (LMIC) is sparse. In high income countries (HICs) well established nutritional care plans, commercial products and good psycho-social support are available.1 A multitude of complications arise due to malnutrition leading to poor quality of life.2 Here we investigated the nutritional status of children included in the Sri Lankan Cerebral Palsy Register (SLCPR).METHODS The study included 768 children aged 0–18 years with CP, attending three teaching hospitals in the Western Province, from September 2018 to November 2021. Data included clinical profile and anthropometry [weight (Kg), height (cm), BMI, mid upper arm circumference (MUAC) (cm), and OFC (cm)] based on WHO. Average was calculated using three repeated measurements. Children who could not stand independently (GMFCS level 4/5) underwent height estimations with the knee height equation: height = (2.69 X Knee height) + 24.2.Indicators used to measure the nutritional status were: weight for age Z score (WAZ), height for age Z score (HAZ), weight for height Z score (WHZ), BMI for age Z score (BAZ), and MUAC for age Z score (MUACZ). WHO Anthro and WHO AnthroPlus software calculated all Z scores.4 HAZ and BAZ were calculated for children aged <18 years, WAZ was calculated for children aged <10.1 years, and WHZ and MUACZ were calculated for children aged <5.1 years. The z scores < -2.0 SD were categorized as underweight (WAZ), stunted (HAZ), wasted (WHZ or MUAC), thin (BAZ).RESULTS Total of 768 children (mean age 59.6 months, SD 44.9, 62.5% males) participated. There were (n=431) children under 61 months and (n=520) from 0–10 years. Of them, 51.3% (n = 267/520) were underweight, 59.8% (n = 258/431) were stunted and 27.3% (n = 210/768) were thin. Among children aged < 5 years, 26.7% (n = 115/431) had severe wasting and severe acute malnutrition (SAM) according to MUACZ < -3SD. Both underweight and stunting were significantly higher among children with spastic CP compared with others (p<0.05). In the 5–19 year group 16.9% (n= 57/337) were obese (BAZ > + 2SD).CONCLUSION Predominant stunting and underweight in this population calls for urgent action to minimize chronic malnutrition. It is imperative to further explore nutritional intake and feeding difficulties in this group and offer structured nutritional care plans. The trend observed in older children towards obesity possibly indicates the need for coordinated nutrition and exercise programmes. It is recommended to regularly monitor growth and nutritional status of all children with CP as there may be serious implications for their activity levels.Item Assessment of knowledge, attitudes and practices on chemotherapy among oncology patients(Sri Lanka Medical Association, 2023) Chandrasena, W.M.H.N.M.INTRODUCTION: Oncology patients are highly susceptible to untoward effects of chemotherapy. Their knowledge, attitude and practice (KAP) on chemotherapy are effective determinant of their treatment. OBJECTIVES: The objective of this study was to assess the KAP regarding chemotherapy medications among oncology patients. S171 METHODS: A total of 311 oncology patients undergoing chemotherapy were randomly recruited from a medical oncology ward in a tertiary care hospital in Sri Lanka. The admission register was used as the sampling frame. Data were collected using a translated version of a standard questionnaire developed by Yan Wang et al. It included questions related to patients’ KAP on chemotherapy medications. The collected data were descriptively analysed. RESULTS: Among participants 68.8% had an average knowledge of their chemotherapy medications, 62.1% had a positive attitude, and 31.2% had reported an average score for good practices. Age, education level and type of cancer significantly influenced the KAP of oncology patients on chemotherapy. CONCLUSIONS: Among participants 68.8% had an average knowledge of their chemotherapy medications, 62.1% had a positive attitude, and 31.2% had reported an average score for good practices. Age, education level and type of cancer significantly influenced the KAP of oncology patients on chemotherapy.Item Frozen shoulder following cardiac surgery; Sri Lankan experience(Sri Lanka Medical Association, 2023) Kurukulasuriya, S.A.F.; Mettananda, K.C.D.; Jayaratne, K.I.W.G.M.N.INTRODUCTION: A high incidence of frozen shoulder (FS), of up to 33% is reported in patients undergoing cardiac surgery, which is tenfold higher than in the normal population. Early diagnosis and treatment may prevent progression to chronic, treatment-resistant disease. OBJECTIVES: To study the incidence and associations of acute FS among a cohort of Sri Lankans undergoing coronary artery bypass graft, valve replacement or both cardiac surgeries. METHODS: An observational study was conducted in selected private-sector hospitals in Colombo. Sample size computed was 142 (110 males, mean age 60.28 yrs.) and convenience sampling technique was used where consecutive eligible patients were selected until the required sample size was S149 fulfilled. Patients were recruited to the study while in hospital and reviewed at the two-week and three-month routine follow-up visits. Interviewer administered questionnaire was used to document the demographic data and risk factor associations. Patients presenting with pain and restricted movement of the shoulder joint with positive limitation in lateral rotation, abduction, and medial rotation (LAM test) were considered as having frozen shoulders. RESULTS: Of the142 patients 40.1%(n=57) developed shoulder pain 38.7%(n=55) were LAM test positive. 38.7% (n=55) with both LAM test positivity and shoulder pain were confirmed as having FS. The highest number of patients developing FS were from the 50-60year age group (n=25). Of the associations, dyslipidaemia and ischemic heart disease had significant correlation with the diagnosis of FS (p value<0.05). CONCLUSIONS: More than one third of patients undergoing cardiac surgery developed FS. Ishaemic heat disease and dyslipidaemia showed significant correlation.Item Anthropometric knee profile measurements on articulator surface of femur among Sri Lankan population.(Sri Lanka Medical Association, 2023) Fernando, G.K.S.; Ranaweera, L.; Cabral, L.L.E.; Dissanayaka, P.; Bandara, I.D.M.R.N.; Sovis, W.F.U.N.INTRODUCTION: In Sri Lankan context there are no published data for articulator surface measurements for knee joints. Forensic, Anatomical, Archaeological, Bio-medical engineering, development of knee S145 prosthesis beneficial with anthropometrics. Digital Vernier Caliper (measuring range 0-140mm, resolution 0.02mm, accuracy ±0.01mm) used to obtain measurements. OBJECTIVES: The aim of this study, was to provide standard anthropometrics for the distal femur in Sri Lankan context. METHODS: Dried adult Femurs (42 male and 28 female) were analysed for the measurements of Medial condyle Antero-Postero Length (MAP), Anteroposterior length of intercondylar area (AP), Medial-Lateral Length (ML), Aspect Ratio (ML/AP) and Epi Condylar breadth (EB). Sex Dimorphism Ratio (SDR) were calculated for dry femurs. RESULTS: The mean values for male; MAP 24.95(±2.22), AP 25.47(±2.27), ML 20.82(±2.56), Aspect Ratio 0.82(±0.11) and EB 7.68(±0.43). The mean values for female; MAP 24.95(±3.08), AP 25.47(±3.16), ML 20.82(±2.28), Aspect Ratio 0.82(±0.18) and EB 7.68(±0.37). SDR values are MAP 107.74, AP 107.12, ML 99.04, and EB 106.55. CONCLUSIONS: The majority of SDR values lie above 100. Therefore, a difference between male and female values can be observed. Findings offer assistance to develop knee joint prostheses with culture-particular values, fitting for the Sri Lankan setting and pave the pathway to the studies on the above-mentioned fields in the local and international context. Sex determination is a crucial element in the creation of a biological profile since it offers information for identities.Item Hepatocellular carcinoma in Sri Lanka: Where do we stand?(Sri Lanka Medical Association, 2013) Siriwardana, R.C.; Liyanage, C.A.H.L.; Jayatunge, D.S.P.; Dassanayaka, A.; Gunetileke, M.G.; Niriella, M.A.; Sirigampola, C.; Upasena, A.; de Silva, H.J.INTRODUCTION AND OBJECTIVES:Hepato-cellular carcinoma (HCC) is the sixth commonest cancer worldwide. We studied 105 consecutive patients with HCC in a single tertiary care centre. METHODS: North Colombo Liver Unit maintains a prospective database of HCC since September 2011. There were 105 entries by February 2013. Decision on the best form of treatment was taken at a multidisciplinary meeting. RESULTS: The median age at presentation was 63 years (range 12-79). Patients were predominantly male 93 (87%). Alcohol consumption above the safe limit was reported in 47 (45%). Hepatitis B surface antigen or C antibody was not detected in any of the patients. Background liver cirrhosis was evident in 59 (79%). Forty two (46%) patients had single nodular tumours while in 20 (21%) it was diffusely infiltrating. Portal vein invasion was seen in 22 (20 %). Median alpha-feto protein (AFP) level was 57.25 mg/ml (1.16- 94120 ng/ml; n=72). Twenty four (33%) patients had AFP level > 400u/l. Surgery was performed in 20 (19%), liver transplant in 2 (1.9%), radio frequency ablation or alcohol ablation in 8 (7.6%), trans arterial chemo embolization (TACE) in 44 (41.9%) and sorafmib was prescribed in four patients. Overall mean survival was 15 months. In the ‘no treatment’ group, mean survival was 4 months. Surgery group had a mean survival of 20 months. CONCLUSION: Hepatitis B is not a risk factor for HCC in Sri Lankans. Median survival without treatment is 4 months.Item Chracterisation of beta giobin mutations in Sri Lankan patients with betathalassaemia intermedia(Sri Lanka Medical Association, 2013) Perera, S.; Silva, D.P.S.I.; Hapugoda, M.; Wickramarathne, M.N.; Wijesirwardhena, I.; Efremove, D.G.; Fisher, C.A.; Weatherall, D.J.; Premawardhena, A.P.INTRODUCTION AND OBJECTIVES: Patients with beta thalassaemia intermedia account for a third of patients attending thalassaemia clinics in Sri Lanka. They show immense phenotypic diversity, the genetic basis for which has not been identified so far. Objective were to characterise beta globin gene mutations in Sri Lankan thalassaemia intermedia patients and to determine how it to influences disease severity. METHODS: We identified 64 thalassaemia intermedia patients from the five main thalassaemia centers; Anuradhapura (n= 6), Kuruncgala (n= 4), Ragama (n= 42), Badulla (n=7) and Chilaw (n=5). Their beta globin DNA sequences were analyzed using ABI PRISM 313lx genetic analyser. RESULTS: Of sixteen patients identified to be homozygous for beta mutations, eleven carried mild beta alleles, IVSI 5 G_C (n= 10) and a rare homozygous promoter mutation - 90 C_T (N=l). Other five were shown to have different types of severe iputations in homozygous state. Nearly half the sample (n=39) was heterozygous for beta mutations. Of them 33 showed mild to severe mutation in one of the alleles IVSI-5 G_C (n=12), IVSI-1 G_A (n= 11) were the commonest. Two patients who were hetcrozygones for beta mutation had a highly unstable Hb variant haemoglobin Mizuho causing severe haemolytic anacma. Hb variants Hb G-Szuhu and Hb G-Coushatta were identified in two patients. CONCLUSIONS: We identified types of beta mutations in some patients with thalassaemia intermedia, which account for the clinical severity.
