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.
Accidental and deliberate self-poisoning with medications and medication errors among children in rural Sri Lanka
(Hindawi Pub. Corp., 2020) Dayasiri, K.; Jayamanne, S. F.; Jayasinghe, C. Y.
ABSTRACT: Context. Pharmaceutical products are the leading cause accidental poisoning in middle- and high-income countries. Patterns of poisoning with medicinal drugs change across different geographic regions and over decades owing to variability in prescription practice, sociocultural factors, safe storage of medicines, and free availability of over the counter medications. Methods. This multicentre descriptive study was conducted over a seven-year period (February 2007 to January 2014) to assess patterns and trends of medicinal drug-related poisoning among children less than 12 years of age in thirty-six hospitals across rural Sri Lanka. Children with both accidental and deliberate medication poisonings and medication errors were recruited to the study. Data on poisoning events and medication errors were gathered via patient/parent interviews using multistructured questionnaires that assessed demographic factors, first aid measures, location and circumstances of poisoning, clinical management, and complications. In addition, focus group discussions were performed on all children and their families who had deliberate poisoning events and medication errors. Results and Conclusions. Among 1621 children presented with acute poisoning over seven years of age, 410 children had acute poisoning with medications. Male children (225, 54.9%) outnumbered female children. Paracetomol (137, 35.6%), salbutamol (55, 14.3%), and chlorpheniramine (35, 9.1%) were the most commonly poisoned medications. Prospective data at Anuradhapura teaching hospital (n = 112) revealed that unsafe first aid measures were practiced on 22 (19.6%) children. Although the majority of children remained asymptomatic (61, 54.5%), neurological symptoms (34, 67%) were predominantly seen in symptomatic children. The majority of poisonings took place within home premises (76, 67.9%). There were 16 reports of medication errors (14.2% of acute poisoning events) either due to erroneous administration by caregivers or erroneous issue of medicines by health workers. The current study did not observe mortality following medication poisonings. This study brings to light the burden of medicinal drug-related poisoning morbidity among children in rural Sri Lanka. Potentially, interventions such as community educational initiatives, written safety warnings, increased use of child resistant containers, and enforcement of laws to bring down accidental medication poisonings need to be implemented, and their effectiveness should be evaluated.
Acute appendicitis during the recovery phase of dengue hemorrhagic fever: two case reports
(BioMed Central, 2022) Thadchanamoorthy, V.; Ganeshrajah, A.; Dayasiri, K.; Jayasekara, N.P.
Background: Dengue fever is one of the most common tropical diseases, with high prevalence in many tropical countries including Sri Lanka. Dengue infection can present from subclinical infection to dengue shock syndrome. Further, the disease also shows a variety of atypical presentations and has been reported to mimic a number of causes of acute abdomen. Case presentation: The authors report two children (a 6-year-old Tamil girl and an 8-year-old Muslim girl) who were diagnosed to have acute appendicitis during the early recovery phase of dengue hemorrhagic fever (DHF) and late recovery period of dengue hemorrhagic fever with platelet count of 92 × 103/cumm and 102 × 103/cumm, respectively. Both children were investigated with abdomen ultrasound as they developed severe abdominal pain and tenderness on palpation during the recovery phase, which was felt to be very unusual. Acute appendicitis was diagnosed in one child, while the other child had a ruptured appendicular abscess. Both children were treated with laparoscopic appendectomy and a 7-day course of intravenous antibiotics. Both children were reviewed in 1 month following treatment and had complete recovery. Conclusion: Although precise pathophysiology and associations of the surgical abdomen with dengue fever remain to be elucidated, there are known factors in dengue fever that can potentially lead to secondary bacterial infections and surgical abdomen. Awareness and increased suspicion by the clinician are paramount to detect such complications early, especially in children who demonstrate unusual clinical features during various stages of dengue infection.
Acute hemolytic crisis complicated with ischemic cardiac injury and methemoglobinaemia following ingestion of naphthalene: a case report
(BioMed Central, 2024-12) Dayasiri, K.; Pathiraja, H.; Thadchanamoorthy, V.
BACKGROUND Naphthalene is an aromatic hydrocarbon that potentially produces methemoglobinaemia but rarely causes hemolysis, especially in children with underlying glucose-6-phosphate dehydrogenase deficiency. Although ingestion of a single moth ball by an older child may not be life threatening, it can be fatal if ingested by a toddler. CASE PRESENTATION A 2-year-old Singhalese boy developed acute severe hemolysis and methemoglobinaemia following ingestion of a mothball. On admission, the patient was ill and pale. The child was tachycardic and tachypnoiec with oxygen saturation of 76% on air. Blood investigations showed significant anemia, elevated reticulocytes, and evidence of hemolysis in a blood picture, along with elevated lactate dehydrogenase and indirect bilirubin. Child also had ST depressions on electrocardiogram examination with negative troponin-I. He was given four packed red blood cell (PRBC) transfusions and was successfully discharged in 3 days time following optimal supportive treatment. A glucose-6-phosphate dehydrogenase assay confirmed the diagnosis of glucose-6-phosphate dehydrogenase deficiency in this child: 0.9 U/gHb (4.0-13.0 U/gHb).CONCLUSION This case report highlights a rare life-threatening presentation of naphthalene ingestion in a child with previously undiagnosed glucose-6-phosphate dehydrogenase deficiency. Ingestion of even a single moth ball can be fatal in vulnerable children given the altered toxicokinetics of naphthalene in children.

Approach to the adolescent with substance use in the acute Setting
(Cureus, Inc., 2021) Sathanantham, S.; Dayasiri, K.; Thadchanamoorthy, V.
ABSTRACT: Psychoactive substance use during adolescence is an emerging challenge to the public health system due to the potential negative impact on the emotional, cognitive, social, physical and academic outcomes of adolescents. An increase in autonomy during adolescence, peer influence and willingness to experiment, lead to taking high-risk decisions subsequently prompting towards substance abuse and alcohol use. Substance use is heterogeneous among adolescents, which differs with availability, perceptions of use and specific drug usage. In adolescents' substance abuse, beyond emergency care, brief counselling with psychosocial assessment and follow up are recommended for successful management. The article reviews the common substances used by adolescents, types of presentations, clinical evaluation of patients and their background, laboratory testing, emergency management and follow up for long-term management. KEYWORDS: adolescent; intoxication; mental health; substance; supportive care.
Arthrogryposis multiplex congenita in a child with congenital fractures: a case report
(BioMed Central, London, 2022) Dayasiri, K.; Jayaweera, H.
Background: Bruck syndrome is an exceedingly rare form of osteogenesis imperfecta, inherited autosomal recessively and presenting with the concurrence of bone fragility and congenital contractures of large joints. The disease usually progresses relentlessly to result in recurrent fractures, short stature, severe kyphoscoliosis, and susceptibility to recurrent respiratory tract infections.Case presentation: The index child was a male newborn to healthy, nonconsanguineous, Sinhalese parents. The child had multiple contractures involving all large joints with pterigium formation in addition to congenital fractures involving left humerus and ulna at birth. The phenotypic features in this child were highly suggestive of Bruck syndrome. Genetic counseling was offered to the parents, although specific genetic testing could not be undertaken due to lack of resources. Bone and skin biopsy were not performed since only palliative care was possible. Over the course, he developed recurrent severe chest infections due to poor muscle tone, weak cough reflex, and pooling of secretions. Unfortunately, he succumbed at the age of 7 months following severe pneumonia.Conclusion: The association of arthrogryposis with osteogenesis imperfecta is extremely rare and known as Bruck syndrome. Early diagnosis during the antenatal period is helpful in genetic counseling, assessment of severity, and exploration of therapeutic options.
Atypical Kawasaki disease presenting with macroscopic hematuria in an infant: a case report
(BioMed Central, 2023) Thadchanamoorthy, V; Dayasiri, K.; Ragunathan, I.R.
BACKGROUND: Kawasaki disease is an acute febrile condition in children. It affects mainly children under 5 years old, and is known to cause coronary artery abnormalities if treatment is delayed. The diagnosis rests mainly on clinical criteria. However, it is also known that some infants do not have diagnostic criteria sufficient enough for the diagnosis of Kawasaki disease. Further, children may rarely present with unusual features, and this entity is recognized as "Atypical Kawasaki disease." CASE PRESENTATION: We present the case of a 9-month-old Tamil boy who presented with sterile gross hematuria in association with prolonged fever, lymphadenopathy, and generalized maculopapular rash. He had high inflammatory markers and echocardiogram disclosed left coronary artery dilatation. The diagnosis of incomplete Kawasaki disease was confirmed based on clinical grounds supported by investigations and exclusion of differential diagnosis. The child showed a good response to intravenous immunoglobulin and aspirin. CONCLUSION: Kawasaki disease is one of the important differential diagnoses of protracted fever of unknown origin in very young children. Since delayed treatment is associated with a high risk of complications, atypical Kawasaki disease needs to be suspected in children presenting with unusual features such as macroscopic hematuria that occurs in association with unexplained prolonged fever.
Autoimmune hepatitis and acquired partial lipodystrophy.
(BMJ Pub. Group,London, 2022) Bakewell, C.; Dayasiri, K.; Brown, R.M.; Rodrigues, A.; Williams, R.; Anand, G.; Gupte, G.L.
The lipodystrophies are an extremely rare group of metabolic conditions which are categorised based on their pathogenesis and phenotype. While primarily known for the striking loss of subcutaneous adipose tissue which they induce, they may also be associated with significant liver injury. In most cases, this results from the secondary deposition of lipid within hepatic parenchyma and is seen predominantly in generalised lipodystrophy. More rarely, patients may develop autoimmune hepatitis. We report a rare case of a 17-month-old boy who developed features of acquired partial lipodystrophy in association with anti-LKM1-positive autoimmune hepatitis following initial presentation with a Henoch-Schönlein purpura-like illness. We describe his challenging path to diagnosis and discuss his ongoing management in an effort to further our understanding of this rare but significant association. This report highlights the need for close clinical observation and a high index of suspicion for recognising early features of lipodystrophy.

Epidemiological patterns and trends of paediatric snakebites in Sri Lanka
(Biomed Central, 2024-12) Dayasiri, K.; Caldera, D.; Suraweera, N.; Thadchanamoorthy, V.; Hettiarachchi , M.; Denipitiya, T.; Bandara, S.
OBJECTIVES This study aimed to analyse the epidemiological patterns of paediatric snake bites in Sri Lanka over a 4-year period (2020-2024).METHODS A multi-centre, retrospective observational study was conducted from June 2020 to June 2024 across nine governmental hospitals in seven provinces of Sri Lanka. Data were collected based on 757 children presenting with snake bites. The snake bites were analysed based on age, gender, and seasonal variations. Data on the type of snake involved, geographic variations and the temporal trends in snake bite occurrences were also analysed.RESULTS The mean age of the 757 children recruited to the study was 10.3 years (SD-5.00, range-0.1-17 years). Males (57.7%) were significantly more affected than females (42.3%) (p < 0.05). Visual identification confirmed the snake species in 58.4% of cases. The hump-nosed viper (16.7%), Russell's viper (14.7%), and common krait (12.9%) were the most common medically important snakes identified in the study. Seasonal peaks in snake bites occurred in May-July and November-December. An increasing trend in snake bite incidence was noted over the first three years, with a slight decline in the final year.CONCLUSION Paediatric snake bites in Sri Lanka show significant age, gender, and seasonal patterns. Targeted public health interventions are needed to mitigate the impact on children.
Epidemiology of acute poisoning among children in urban Sri Lanka: the experience of two tertiary care hospitals in Colombo district
(The Jaffna Medical Association, 2023) Dayasiri, K.; Thadchanamoorthy, V.; Jansz, M.; Dassanayake, S.; Anand, G.
Acute poisoning in children is an important public health problem and one of the leading causes of emergency department admissions following childhood injuries. Although most paediatric ingestions are accidental, children are at a higher risk for serious complications following ingestion of a similar toxic dose compared to adults. The current study evaluated the recent patterns and trends in acute poisoning among children in two tertiary care centers in urban Sri Lanka: Lady Ridge Hospital for Children, Colombo and North Colombo Teaching Hospital, Ragama. Out of 200 cases, the majority were between 1-5 years and male children outnumbered female children. The most common poisons included kerosene oil, paracetamol and “Good Luck” plants. Complication rate was low, and no mortalities were reported. Deliberate poisoning accounted for 1% of total poisonings. The current trends in poisoning among children living in urban Sri Lanka showed decreasing incidence of pesticide poisonings and increasing incidence of pharmaceutical poisonings and poisoning with ornamental plants.
Expanded dengue syndrome presenting with acute liver failure, acute kidney injury, pancreatic involvement, coagulopathy, and multiple intracranial hemorrhages in a young child: a case report
(BioMed Central, 2022) Thadchanamoorthy, V.; Dayasiri, K.
Background: Dengue is a mosquito-borne viral infection that typically occurs in tropical and subtropical countries. The clinical manifestations of dengue infection range from an asymptomatic subclinical course to severe dengue shock syndrome. Besides, dengue can affect any organ in the body and can present with atypical manifestations. Case presentation: We report a 6-year-old previously healthy Tamil child who had dengue complicated with multiorgan involvement. She initially presented with high fever, headache, body aches for 5 days, blood and mucus diarrhea, hematuria, and right knee joint swelling for 2 days. Dengue NS1 antigen was positive on day 2 of febrile illness. She was managed symptomatically in the local hospital for 3 days and transferred to the tertiary care hospital for further management. She was eventually diagnosed as having dengue hemorrhagic fever complicated with multiorgan involvement including acute liver failure, pancreatic involvement, coagulopathy, arthritis, acute kidney injury, and multiple intracranial hemorrhages. The constellation of disease manifestations was identified as expanded dengue syndrome. She was managed with fresh blood, platelet, and cryoprecipitate transfusions and intravenous antibiotics in addition to renal and liver support in the intensive care unit. On day 14 of illness, she deteriorated while on the ventilator and died due to multiple intracranial hemorrhages. Conclusion: The reported child with dengue hemorrhagic fever developed several unusual presentations such as acute liver and renal failure, disseminated intravascular coagulopathy, pancreatic involvement, and multiple intracranial hemorrhages, which form part of expanded dengue syndrome. In the seriously unwell child, it is important to look for unusual complications actively to improve outcomes.
Expanding the phenotype of DYNC1H1-associated diseases with a rare variant resulting in spinal muscular atrophy with lower extremity predominance (SMA-LED) and upper motor neuron signs
(Hacettepe Medical Center, 2023) Lee, J.; Millington, P.; Dayasiri, K.; Ramdas, S.; Jayawant, S.; Anand, G.
BACKGROUND: Spinal muscular atrophy with lower extremity predominance (SMA-LED) is an autosomal dominant disorder. Since SMA-LED affects lower motor neurons, the disease is characterized by weakness and atrophy of lower limb muscles. We present a familial case series of SMA-LED with upper motor neuron signs associated with a rare variant in DYNC1H1. CASE: The index case was referred to Pediatric Neurology at the age of two and half years, due to delayed mobility. The child was diagnosed with congenital vertical talus at birth, which was managed with serial bilateral casting and surgery. The delayed mobility was initially attributed to lower limb weakness secondary to prolonged periods of immobilization from casting of his lower limbs. He had a striking waddling gait and proximal muscle weakness on neurological assessment. He had lower motor neuron signs predominantly in his lower limbs that were in keeping with SMA-LED. Surprisingly, he also demonstrated a brisk crossed adductor response that was not in keeping with an isolated primary neuro-muscular disorder and suggested a mixed upper and lower motor neuron pathology. The inherited neuropathy gene panel revealed a heterozygous sequence change in the DYNC1H1 gene which was present in all affected family members. CONCLUSIONS: We present the first report of a familial case series of SMA-LED with upper motor neuron signs associated with an extremely rare variant in DYNC1H1: c.1808A > T (p.Glu603Val). As per the American College of Medical Genetics and Genomics (ACMG) guidelines for variant classification, we would recommend that this variant be reclassified as `Likely Pathogenic` due to matching 1 moderate (PM1-PM6) and ≥4 supporting (PP1-PP5) criteria in the reported case series.
Fifteen-minute consultation: Evaluation of paediatric torticollis.
(BMJ Pub. Group, 2023) Dayasiri, K.; Rao, S.
Torticollis refers to a state in which the neck is twisted due to excessive contraction or shortening of the muscles on one side. Congenital muscular torticollis, which is more common than acquired torticollis, has an incidence of 0.3%-1.9% among all live births. The clinical approach to torticollis depends on the age at presentation, duration of torticollis and presenting symptoms. The underlying aetiology for torticollis varies with the age of the child. Torticollis can be a presenting feature for life-threatening conditions and thus requires careful evaluation.
Fifteen-minute update: International normalised ratio as the treatment end point in children with acute paracetamol poisoning
(BMJ Pub. Group,London, 2023) Dayasiri, K.; Rao, S.
Paracetamol is one of the most frequent reasons for poisonings across the UK with an estimated 90,000 patients and 150 deaths annually. International normalised ratio (INR) may be elevated due to hepatocellular damage and is frequently used to monitor progress on N-acetyl cysteine. N-acetyl cysteine is associated with reduced activity of vitamin K dependent clotting factors leading to a benign elevation of INR. In asymptomatic children with normal aspartate transaminase/alanine transaminase, isolated borderline elevation of INR following paracetamol overdose should be reviewed for possible N-acetyl cysteine induced elevation of INR. Due to these factors, in those with borderline persistent elevation of INR, N-acetyl cysteine can be safety stopped if INR is falling on two or more consecutive tests and is <3.0.
