Item Current approaches to instrumental assessment of swallowing in children(Current Science, 2018) Dharmarathna, I.; Miles, A.; Allen, J.E.PURPOSE OF THE REVIEW: This article reviews recent developments in the instrumental assessment of swallowing in children with a specific focus on research published between January 2017 and June 2018. RECENT FINDINGS: Instrumental swallowing assessments reported in the time period included: videofluoroscopic study of swallowing, digital cervical auscultation, dynamic ultrasound, high-resolution impedance manometry, nasal airflow thermistry and respiratory inductance plethysmography. Several studies were found exploring tools to objectively quantify videofluoroscopic study of swallowing data; swallowing from the mouth through to stomach was addressed including approaches to analysing mastication as well as evaluating oesophageal motility disorders. SUMMARY: Even though a vast range of instrumentation were studied, lack of clarity on clinical feasibility and objective measures that facilitate medical decision-making in practice mean further research is required to provide guidance on implementation. Promising novel approaches to aid the quantification of swallowing physiology from the mouth, pharynx and through to the oesophagus are emerging.Item Neurocognitive skills in children with congenital hypothyroidism attending the endocrine clinic of the Professorial Unit of the Lady Ridgeway Hospital for Children, Colombo.(Sri Lanka College of Paediatricians, 2017) Sumanasena, S.P.; Gunawardena, N.; Dissanayake, B.; Dilanka, S.; de Silva, S.This is the correspondence to the article appeared in Sri Lanka Journal of Child Health. 2016; 45 (2):95-102. by same authors,Item Neurocognitive skills in children with congenital hypothyroidism attending the endocrine clinic of the Professorial Unit of the Lady Ridgeway Hospital for Children, Colombo(Sri Lanka College of Paediatricians, 2016) Sumanasena, S.P.; Gunawardena, N.; Dissanayake, B.; Dilanka, S.; de Silva, S.BACKGROUND: Early thyroxine replacement prevents intellectual impairment due to congenital hypothyroidism (CHT). There is minimal evidence on neurodevelopmental outcome of children commenced on thyroxine during early infancy from countries not screening for CHT. OBJECTIVE: To assess the neurocognitive skills of children with CHT of age group 6-10 years, attending the endocrine clinic of the Professorial Paediatric Unit, LRH compared to age matched controls and to assess the influence of age at diagnosis, initial thyroid stimulating hormone (TSH) levels, thyroxine commencement dose and number of clinic visits in the first year on neurocognitive skills. METHOD: A retrospective study was carried out from 1st January 2010 to 1stJanuary 2011 on children with CHT of age group 6-10 years, followed up in the endocrine clinic of the Professorial Paediatric Unit, LRH. Age matched healthy children aged 6-10 years were selected from similar socioeconomic backgrounds to compare the neurocognitive attainments. Neurocognitive skills were assessed using an age appropriate battery of instruments. Children older than 10 years were excluded as the assessment tools were designed only for the age range 6-10 years. Children with other co-morbidities adversely affecting their neurocognitive development were also excluded. RESULTS: Twenty three children with CHT of age group 6-10 years were followed up in the endocrine clinic of the Professorial Paediatric Unit, LRH during the study period and 2 were excluded. Forty two age matched controls of age group 6-10 years also participated in the study. The mean age of the children was 2.42±2.59 years. The mean TSH levels at diagnosis was 43.17± 34.25mU/L. Starting dose of thyroxine in the majority was less than 10µg/kg/day. Children with CHT performed less than their peers in all age ranges and in all areas of skills. Statistically significant differences were documented in the total performance percentiles at ages of 8 (p=0.0001) and 9 years (p=0.0002). Similarly, they performed less in literacy at 8 (p=0.015) and 9 years (p=0.004), verbal performance at 8 years (p= 0.0002) and numeracy in 9 years (p=0.035). There was no significant correlation between the neurocognitive scores and age at diagnosis, initial TSH levels, thyroxine commencement dose or the number of clinic visits in the first year. CONCLUSIONS: Children with CHT of age group 6-10 years, attending the endocrine clinic of the Professorial Paediatric Unit, LRH had significantly reduced neurocognitive skills compared to age matched controls. There was no significant correlation between the neurocognitive scores and age at diagnosis, initial TSH levels, thyroxine commencement dose or number of clinic visits in the first year.Item Analysis of nutritional status and factors associated with undernutrition in children aged 6-59 months in a rural area of Sri Lanka(Sri Lanka College of Paediatricians, 2019) Samarasekara, G.S.; Mettananda, S.; Punchihewa, P.OBJECTIVE: To describe the prevalence and factors associated with undernutrition in children aged 6-59 months in a rural area of Sri Lanka. METHOD: A community-based, cross-sectional study was carried out among children aged 6-59 months attending well baby clinics in Dehiattakandiya Medical Officer of Health area from November 2016 to January 2017. Data collection was done using an interviewer-administered questionnaire. Weight and height measurements were taken with calibrated instruments. Data analysis was done using logistic regression by SPSS 16.0. RESULTS: Four hundred and sixty four children were recruited having a mean age of 29.3 ±14.6 months; 53% were females. Prevalence of stunting, underweight and wasting was 36.4%, 42.9% and 19.0% respectively. The following independent associations were identified: for stunting- low birth weight, breastfeeding beyond 2 years, lower maternal education and paternal smoking; for underweight- birth order more than 2, low birth weight, breastfeeding beyond 2 years, lower maternal education and paternal smoking and alcohol use; for wasting- male sex, low birth weight and paternal smoking. CONCLUSIONS: Low birth weight, prolonged breastfeeding, lower maternal education level and paternal smoking had a significant association with stunting and underweight whilst male sex, low birth weight, and paternal smoking had a significant association with wasting in children aged 6-59 months.Item The Effectiveness of using the colourful semantics approach to support language development with children who are deaf or hard-of-hearing(Taylor & Francis, 2019) Hettiarachchi, S.; Ranaweera, M.ABSTRACT: The lack of early identification, suboptimal language stimulation and limited remedial services in Sri Lanka for children who are deaf or hard-of-hearing place them at-risk of language delay. The reality for many preschool and primary school children entering formal education in Sri Lanka is a language delay in spoken language and/or sign language compared to their age-matched hearing peers. The aim of this study was to evaluate the effectiveness of the Colourful Semantics approach as a whole-class language enrichment programme to develop the use and responses to target wh questions. Thirty primary school children who are deaf or hard-of-hearing between the ages of five-ten years were included. The programme was offered once a week for 12 weeks through the class teacher. Individual pre- and post-language measures and statistical analyses were undertaken on receptive knowledge and expressive use of the target wh questions using a picture naming task and tasks based on three local children’s story books. A statistically significant improvement was observed in the understanding of target wh questions post-intervention by all the children. There was also a positive change in the responses to the target wh questions by all the children post-intervention with many combining signs or spoken words with signs. The Colourful Semantics approach has potential as a whole-class language-teaching approach to strengthen the understanding and use of wh question forms. This study emphasizes the benefits of collaborative partnerships between speech and language therapists and teachers in delivering intervention particularly in resource-limited contexts.

This study explores the associations between socioeconomic status and the double burden of malnutrition among school-aged children and within their household. A total of 543 primary school children aged 5-10 years (204 boys and 339 girls) in Gampaha District, Sri Lanka, were included in the analysis. The nutritional statuses of thinness, normal, overweight, and obesity for children and mothers were defined according to WHO growth references and body mass index. Maternal education, household equivalent income, and maternal employment were used as socioeconomic status indicators. The proportion of child thinness and overweight was 19.3% and 13.4%, respectively, and that of maternal overweight (body mass index ≥ 25 kg/m2) was 36.5%. A positive correlation was found between maternal body mass index and the child's body mass index for age z-score in older boys and younger girls. A multivariate stepwise logistic regression analysis showed that lower education of mothers posed a higher association with child thinness (adjusted odds ratio = 2.33, 95% confidence interval: 1.08-5.00). Mothers with overweight and obesity were less likely to have a child with thinness (adjusted odds ratio = 0.30, 95% confidence interval: 0.16-0.58). Maternal employment status and household equivalent income were not significantly, but marginally, associated with child overweight and obesity. Socioeconomic inequality combined with maternal nutritional status affected child malnutrition. These findings suggest that the underlying circumstances within households should be considered to improve child malnutrition.

Studies were included if they prospectively assessed HRQoL in children with functional constipation according to the Rome criteria. Articles were excluded if patients had organic causes of constipation and if HRQoL was only assessed after successful therapeutic interventions. A meta-analysis was performed calculating sample size-weighted pooled mean and SD of HRQoL scores. The quality of the studies was also assessed.RESULTS:A total of 20 of 2658 studies were included, providing HRQoL data for 2344 children. Quality of evidence was considered to be poor in 9 of the 20 studies (45%); 13 of the 20 studies reported sufficient data to be included in the meta-analysis. Pooled total HRQoL scores of children with functional constipation were found to be lower compared with healthy reference samples (65.6 vs 86.1; P < .01). Similar HRQoL scores were found according to self-report and parent proxy report. Hospital-based studies reported lower HRQoL scores as compared with community-based studies. Two studies reported on HRQoL scores of children with and without fecal incontinence, but no significant difference was found.CONCLUSIONS:HRQoL is compromised in children with functional constipationItem Efficacy of a low-cost multidisciplinary team-led experiential workshop for public health midwives on dysphagia management for children with cerebral palsy(VU e-Publishing, Netherlands, 2018) Hettiarachchi, S.; Kitnasamy, G.; Mahendran, R.; Nizar, F. S.; Bandara, C.; Gowritharan, P.PURPOSE: Over the past decade there has been a growing focus on offering appropriate training to healthcare professionals and caregivers to support safe feeding practices for children with cerebral palsy. Early and consistent multidisciplinary intervention is required to minimise the risks of aspiration pneumonia. The high incidence of complications from aspiration pneumonia among children with cerebral palsy in Sri Lanka has made it necessary to conduct low-cost multidisciplinary team-led dysphagia awareness workshops for healthcare professionals and caregivers.METHOD: A group of 38 Public Health Midwives (PHMs) was offered an experiential workshop by a small multidisciplinary team (MDT). To determine changes in knowledge, a self-administered questionnaire that included a video-based client scenario was administered pre- and post-workshop. The data were analysed statistically using non-parametric within-participant t-tests.RESULTS: The post-workshop responses to the questionnaire indicated a significant increase in the level of knowledge. This included positive changes in the understanding and knowledge of cerebral palsy (t (37) =-7.44, p=.000), effects of cerebral palsy on eating and drinking skills (t (37) =-3.91, p=.000), positioning (t (37) = -9.85, p=.000), aspiration (t (37) =-3.46, p=.001), food categorisation (t (37), -3.85, p=.000) and client video observation (t (37)-3.91, p=.000) at a p=.05 level of significance. While there was also an increase in the knowledge on general guidelines during mealtimes, this did not reach statistical significance.CONCLUSION: The low-cost MDT-led experiential workshop was effective in increasing knowledge of feeding and dysphagia-related issues in cerebral palsy among a group of PHMs. This workshop could serve as a model for training PHMs and Community-Health Workers across the country in order to reach the Sustainable Development Goal of ‘good health and well-being’ for children with cerebral palsy and all children experiencing feeding difficulties. Follow-up workshops and continued professional development courses for midwives on dysphagia care are strongly recommended, in addition to collaborative clinical practiceItem A Case of dapsone-Induced severe agranulocytosis causing life-threatening skin Sepsis in a Sri Lankan child with borderline Leprosy: A success story!(Hindawi Pub. Corp, 2019) Fernando, M.; Kankananarachchi, I.; Navabalasooriyar, P.; Herath, B.; Punchihewa, P.Leprosy is a common skin disease in Sri Lanka which is being increasingly diagnosed due to the existing successful public health programme. Dapsone is a drug which holds unique pharmacological properties where it serves as both anti-inflammatory and antimicrobial agents. Of its main adverse effects, agranulocytosis is a serious consequence which is reported mainly in adults and elderly. We report a 7-year-old child who sustained life-threatening skin and subcutaneous tissue sepsis because of dapsone-induced agranulocytosis. Besides, this case highlights the importance of meticulous monitoring of cell counts due to the risk of neutropenia and the natural history of cell recovery following occurrence of neutropenia. Though high mortality rate has been described in most of the similar cases reported, the child we describe made a complete recovery following severe neutropenic sepsis.Item Prevalence of ectoparasitic infections and other dermatological infections and their associated factors among school children in Gampaha District, Sri Lanka(Hindawi Publishing Corporation, 2019) Gunathilaka, N.; Chandrasena, N.; Udayanga, L.Skin disorders are one of the commonest conditions among school children in developing countries. There are only a few published studies available from Sri Lanka on the prevalence of skin disorders. A community-based cross-sectional study was carried out among five government-run schools randomly selected from the district of Gampaha, Sri Lanka, during 2016-2017. A total of 41 students between 5 and 16 years of age were randomly selected from each school. Sociodemographic profile and hygienic behaviors of selected students were assessed using a pretested interviewer-administered questionnaire. Students were examined by a medical officer for the presence of different skin disorders. The chi-squared test of association and binary logistic regression were used for the identification of the significance of socioeconomic factors and hygienic practices among the study participants. A total of 205 school children participated in the study. The commonest skin disorder was pediculosis (42.0%; n=86), followed by dandruff (8.3%; n=17), fungal infections (6.8%; n=14), and scabies (1.5%; n=3). Almost one-fourth of the study participants (22.9%; n=30/131) had more than one disorder, majored by Pediculus captis infestation with dandruff. Over one-third (36.1%; n=74) were free of any skin disorders. The prevalence of skin disorders was significantly high among females (87.3%; n=110), compared to males (26.6%; n=21). Presence of long hair, higher family size, and limited number of rooms in the house were risk factors associated with the prevalence of skin disorders. The commonest skin disorder was pediculosis, while scabies and fungal infections were scarce among school children in the district of Gampaha, Sri Lanka. Implementation of health education and monitoring programs at the school level for maintaining the dermal health status of school children is recommended.
