Abstract
Gastroesophageal reflux disease (GERD) is commonly encountered in clinical practice in Sri Lanka. However, its prevalence in Sri Lanka is unknown. Our objective was to study the island-wide prevalence of GERD symptoms in Sri Lanka and its associated factors. A total of 1200 individuals aged 18-70 years (male: female 1: 1.16, mean age 42.7 years [SD 14.4 years]). were recruited from all 25 districts of the country, using stratified random sampling. An interviewer-administered, country-validated questionnaire was used to assess the GERD symptom prevalence and associated factors. Weight, height, waist, and hip circumference were measured. Heartburn and/or regurgitation at least once a week, an internationally used criterion for probable GERD was used to diagnose GERD. In this study, GERD symptom prevalence was 25.3% (male 42.1% and female 57.9%). Factors independently associated with GERD were inadequate sleep, snacking at midnight, sleeping within two hours of consuming a meal, skipping breakfast, increased mental stress, and certain medications used such as statins, and antihypertensive medications (p<0.001, univariate and logistic regression analysis). 38.4% of the study population have been using medication for heartburn and regurgitation in the past 3 months and 19.8% were on proton pump inhibitors. To conclude, the prevalence of GERD symptoms in Sri Lanka (25.3%) is higher than its estimated global prevalence of 13.8%. Several meal-related lifestyle habits, mental stress, and the use of some medications are significantly associated with GERD, indicating the importance of lifestyle modification and stress reduction in its management.

Abstract
INTRODUCTION Disorders of Gut-Brain Interactions (DGBI) are a common clinical problem in children and pose significant challenges to the attending pediatrician. Radiological investigations are commonly ordered to evaluate these children. AREA COVERED This review focuses on the current best practice of using radiological investigations in DGBIs and how novel radiological investigations could revolutionize the assessment and therapeutic approach of DGBI in children. EXPERT OPINION We believe imaging in DGBI is still in its early stages, but it has the potential to revolutionize how we diagnose and treat children with DGBI. As the understanding of the gut-brain axis continues to grow, we can expect to see the disappearance of conventional imaging techniques and the emergence of more sophisticated imaging techniques with less radiation exposure in the future which provide more clinically meaningful information regarding the gut-brain axis and its influence on intestinal function. Some of the novel imaging modalities will be able to broaden our horizon of understanding DGBI in children providing more useful therapeutic options to minimize their suffering.

Abstract
BACKGROUND/AIMS Stress is a known associated factor for gastroesophageal reflux disease (GERD). However, the dynamics between stress and GERD are not fully studied, especially in Sri Lanka. Our objective was to assess it. METHODS For this cross-sectional descriptive study, 1200 individuals (age ranged 18-70 years, mean 42.7 years [SD 14.4 years], 46.1% males), were recruited using stratified random cluster sampling from all 25 districts of Sri Lanka. An interviewer-administered questionnaire, which included a country-validated GERD symptom screening tool, and the Perceived Stress Scale (PSS), was used to assess GERD symptoms and stress. Probable GERD was defined as those having heartburn and/ or regurgitation at least once per week which is on par with globally accepted criteria. Those who did not fulfill these criteria were considered as controls. RESULTS PSS score was higher in those with probable GERD (mean 13.75 [standard deviation (SD) 6.87]) than in controls (mean 10.93 [SD 6.80]), (p <0.001, Mann-Whitney U test). The adjusted odds ratio for GERD symptoms was 1.96 times higher (95% confidence interval 1.50-2.55) in the moderate to high-stress level compared to the low-stress level participants. PSS score correlated significantly with the GERD screening tool score (R 0.242, p <0.001). Heartburn, regurgitation, chest pain, cough, and burping were significantly frequent in those with moderate to high-stress levels (p <0.001). Those with higher stress scores were more likely to use acid-lowering drugs (p = 0.006). CONCLUSIONS Individuals exposed to higher levels of stress are more likely to have GERD symptoms. Therefore, stress reduction should be an important part of GERD symptom management.

Abstract
Functional diarrhea in children is a disease that has been focused on by both general pediatricians as well as pediatric gastroenterologists across the world. Although it is seen across the pediatric age group from late infancy to adolescence, most still believe that functional diarrhea only occurs in younger children. Recent epidemiological studies have shown that functional diarrhea is prevalent in all subcontinents. The classic clinical features include chronic loose stools with undigested food particles without growth faltering. Although known for long years, pathophysiological mechanisms and therapeutic options are not well explored, and the existing literature is outdated. In this article, authors review the available literature on functional diarrhea, with a reminder that a fresh look is needed to broaden the horizons of understanding of this disease.

Abstract
Many widely held beliefs and assumptions concerning childhood constipation continue to interfere with rational management of childhood constipation. Although many still believe that constipation is not a common disease, about 9.5% of the world's children suffer from chronic constipation. Most of these children live in non-Western countries. There are major misconceptions about the etiology of constipation as a significant proportion of clinicians still believe that constipation is caused by some form an organic pathology, whereas in reality, the majority have functional constipation. Contrary to a commonly held belief that children outgrow constipation without long-term problems, there is evidence that constipation leads to significant bowel and psychological consequences and has a major impact on the quality of life which detrimentally affects future health and education. Finally, ineffective management strategies such as increasing fiber and water in the diet, and short duration of treatment owing to the fear that long-term laxative treatment leads to colonic dysfunction, interfere with effective therapeutic strategies. Conclusions: It is apparent that myths and misconception often lead to wrong assumptions regarding the distribution of the disease, its etiology, pathophysiology, and management leading to ordering incorrect investigations and ineffective therapeutic strategies while spending large sums of public funds unnecessarily. Poorly treated constipation leads to deleterious psychological consequences predisposing children to develop significant psychological damage and bowel dysfunctions. This review aims to challenge these myths about various elements of constipation by exploring the existing literature and encouraging clinicians to have a fresh look at old concepts that could interfere with the well-being of children with constipation. What is Known: • Childhood constipation is a growing problem in the world leading to significant suffering and high healthcare expenditure • Myths and misconceptions lead to poor management strategies causing psychological and bowel damage What is New: • Organic, systemic, and bowel disorders leading to constipation are uncommon, and in the majority, it arises due to deliberate fecal withholding and most investigations ordered by clinicians are not very helpful in the management • Most non-pharmacological interventions are not effective in the day-to-day management of childhood constipation. The use of laxatives is considered to be the first-line management strategy.

Abstract
Objectives Functional abdominal pain disorders (FAPDs) are common gastrointestinal problems in children, and the pathophysiology is thought to be multifactorial. Adverse early life events (ELE) induce alterations in the central nervous system, perhaps predisposing individuals to develop FAPDs. We aimed to study the potential adverse ELE that are associated with FAPDs. Methods We steered a school-based survey involving 1000 children from 4 randomly selected schools. FAPDs were assessed using the translated Rome III questionnaire, and ELE were identified using a pre-tested, parental questionnaire. FAPDs were diagnosed using the Rome III criteria. Results Hundred and eighty-two (182) children had FAPDs (62.1% girls, mean age 8.5, SD 2.1). ELE of them were compared with 571 children without FAPDs (51.1% girls, mean age 8.8, SD 1.9). According to the binary logistic regression analysis, family members with abdominal pain, family member with chronic pain other than abdominal pain, prenatal maternal complications and interventional deliveries, were recognized as potential risk factors for the development of FAPDs. Breast feeding over two years has shown to reduce the prevalence of FAPDs.a. Conclusions Prenatal maternal medical problems are associated a with higher prevalence of FAPDs later in life. Prolonged breastfeeding and normal vaginal delivery could be considered as factors that reduce the vulnerability of developing FAPDs in children. Therefore, minimizing pregnancy-related complications, encouraging vaginal deliveries, and encouraging breastfeeding are potentially valuable measures to prevent FAPDs during childhood.

Abstract
Constipation in children is a major health issue around the world, with a global prevalence of 9.5%. They present to clinicians with a myriad of clinical signs. The Rome IV symptom-based criteria are used to diagnose functional constipation. Functional constipation is also a huge financial burden for healthcare system and has a detrimental impact on health-related quality of life of children. There are various risk factors identified globally, including centrally connected factors such as child abuse, emotional and behavioral issues, and psychological stress. Constipation is also precipitated by a low-fiber diet, physical inactivity, and an altered intestinal microbiome. The main pathophysiological mechanism is stool withholding, while altered rectal function, anal sphincter, pelvic floor, and colonic dysfunction also play important roles. Clinical evaluation is critical in making a diagnosis, and most investigations are only required in refractory patients. In the treatment of childhood constipation, both nonpharmacological (education and de-mystification, dietary changes, toilet training, behavioral interventions, biofeedback, and pelvic floor physiotherapy), and pharmacological (osmotic and stimulant laxatives and novel drugs like prucalopride and lubiprostone) interventions are used. For children with refractory constipation, transanal irrigation, botulinum toxin, neuromodulation, and surgical treatments are reserved. While frequent use of probiotics is still in the experimental stage, healthy dietary habits, living a healthy lifestyle and limiting exposure to stressful events, are all beneficial preventive measures.

Abstract
Background An association has been shown between functional abdominal pain disorders (FAPDs) and asthma. However, the exact reason for this association is obscured. The main objective of this study is to identify the possible underlying pathophysiological mechanisms for the association between FAPDs and asthma using gastric motility and lung function tests. Methods This was a cross-sectional comparative study that consisted of four study groups. Twenty-four children (age 7–12 years) each were recruited for four study groups; asthma only, FAPDs only, both asthma and FAPDs, and healthy controls. Asthma was diagnosed using the history and bronchodilator reversibility test. The diagnosis of FAPDs was made using Rome IV criteria. All subjects underwent ultrasound assessment of gastric motility and pulmonary function assessment by spirometry, using validated techniques. Results All gastric motility parameters, gastric emptying rate, amplitude of antral contraction, and antral motility index, were significantly impaired in children with FAPDs only, children with asthma only, and children with both asthma & FAPDs, compared to controls (p<0.05). Pulmonary function parameters indicating airway obstruction (FEV1/FVC ratio, peak expiratory flow rate, FEF25-75%) were not impaired in children with FAPDs only compared to controls (p>0.05), but significantly impaired in children with asthma and children with both disorders. Antral motility index correlated with the FEV1/FVC ratio (r = 0.60, p = 0.002) and FEF25%-75% (r = 0.49, p = 0.01) in children with both asthma and FAPDs. Conclusions Gastric motor functions were significantly impaired in children with asthma, children with FAPDs, and children with both disorders. Motility index, measuring overall gastric motor activity, showed a significant positive correlation with lung function parameters that measure airflow limitation. Therefore, these diseases might arise as a result of primary disturbance of smooth muscle activity in the airways and gastrointestinal wall, which could be a possible pathophysiological mechanism for this association between asthma and FAPDs.

Abstract
ABSTRACT Functional fecal incontinence (FI) is a worldwide problem in children and comprises constipation-associated FI and nonretentive FI. Irrespective of pathophysiology, both disorders impact negatively on the psychological well-being and quality of life of affected children. A thorough clinical history and physical examination using the Rome IV criteria are usually sufficient to diagnose these conditions in most children. Evolving investigations such as high-resolution anorectal and colonic manometry have shed new light on the pathophysiology of functional FI. Although conventional interventions such as toilet training and laxatives successfully treat most children with constipation-associated FI, children with nonretentive FI need more psychologically based therapeutic options. Intrasphincteric injection of botulinum toxin, transanal irrigation and, in select cases, surgical interventions have been used in more resistant children with constipation-associated FI.

Abstract
INTRODUCTION Functional abdominal pain disorders (FAPDs) and asthma are common ailments affecting both children and adults worldwide. Multiple studies have demonstrated an association between these two disorders. However, the exact reason for this observed association is not apparent. AREAS COVERED The current review has explored available literature and outlined multiple underlying pathophysiological mechanisms, common to both asthma and FAPDs, as possible reasons for this association. EXPERT OPINION Smooth muscle dysfunction, hypersensitivity and hyper-responsiveness, mucosal inflammation, and barrier dysfunction involving gastrointestinal and respiratory tracts are the main underlying pathophysiological mechanisms described for the generation of symptoms in FAPDs and asthma. In addition, alterations in neuroendocrine regulatory functions, immunological dysfunction, and microbial dysbiosis have been described in both disorders. We believe that the pathophysiological processes that were explored in this article would be able to expand the mechanisms of the association. The in-depth knowledge is needed to be converted to therapeutic and preventive strategies to improve the quality of care of children suffering from FAPDs and asthma.

Abstract
Objectives To assess behavioral and emotional problems in children and adolescents with functional constipation and their relationship with psychological maladjustment and health-related quality of life (HRQoL). Design A school-based cross-sectional survey conducted in 8 randomly selected schools from 4 randomly selected districts in Sri Lanka. A previously validated questionnaire was used for data collection. Behavioral and emotional problems were assessed using the Sinhala version of the Child Behavior Check List (CBCL-S/4-18). Constipation was diagnosed by applying the Rome III criteria. Results A total of 1000 questionnaires were distributed, and 913 completed questionnaires were included in the analysis. Sixty adolescents (6.5%) had functional constipation. Scores obtained for isolated psychological problems such as withdrawal (3.1 [3.1] vs. 1.9 [2.4], p<0.001), somatic complaints (3.2 [2.8] vs. 2.3 [2.5], p<0.05) anxiety/depression (5.8 [2.5] vs. 3.9 [3.6], p<0.001), social problems (3.0 [2.7] vs. 2.2 [1.9] p<0.001) and attention problems (5.4 [4.1] vs. 3.9 [3.4], p<0.001), and broadband scale of internalization (12.1 [8.4] vs. 8.3 [7.2], p<0.05) and mean total CBCL-S/4-18 score (29.4 [19.5] vs. 23.2 [17.0], p<0.001) were higher in adolescents with functional constipation. Clinical characteristics, socio-demographic and family factors and psychological maladjustment had no relationship with externalization, internalization and total CBCL-S/4-18 score. Internalization (-0.49, p<0.0001), externalization (-0.30, p<0.05), and total CBCL-S/4-18 (-0.44, p<0.001) scores had a negative impact on HRQoL of adolescents with functional constipation. Conclusions Adolescents with functional constipation are suffering from significant behavioral and emotional problems. These problems negatively affect their HRQoL.

Abstract
Exposure to benzene, toluene and p-, m-, o-xylene (BTX) was studied in 29 gas station attendants and 16 office workers in Sri Lanka. The aim of this study was to assess the exposure level and identify potential exposure mitigating measures. Pre- and post-shift samples of end-exhaled air were collected and analysed for BTX on a thermal desorption gas chromatography mass spectrometry system (TD-GC-MS). Urine was collected at the same timepoints and analysed for a metabolite of benzene, S-phenyl mercapturic acid (SPMA), using liquid chromatography-mass spectrometry (LC-MS). Environmental exposure was measured by personal air sampling and analysed by gas chromatography flame ionization detection (GC-FID). Median (range) breathing zone air concentrations were 609 (65.1-1960) μg/m3 for benzene and 746 (<5.0-2770) μg/m3 for toluene. Taking into account long working hours, 28% of the measured exposures exceeded the ACGIH threshold limit value (TLV) for an 8-h time-weighted average of 1.6 mg/m3 for benzene. Xylene isomers were not detected. End-exhaled air concentrations were significantly increased for gas station attendants compared to office workers (p < 0.005). The difference was 1-3-fold in pre-shift and 2-5-fold in post-shift samples. The increase from pre-to post-shift amounted to 5-15-fold (p < 0.005). Pre-shift BTX concentrations in end-exhaled air were higher in smokers compared to non-smokers (p < 0.01). Exposure due to self-reported fuel spills was related to enhanced exhaled BTX (p < 0.05). The same was found for sleeping at the location of the gas station between two work-shifts. Benzene in end-exhaled air was moderately associated with benzene in the breathing zone (r = 0.422; p < 0.001). Median creatinine-corrected S-phenyl mercapturic acid (SPMA) was similar in pre- and post-shift (2.40 and 3.02 μg/g) in gas station attendants but increased in office workers (from 0.55 to 1.07 μg/g). In conclusion, working as a gas station attendant leads to inhalation exposure and occasional skin exposure to BTX. Smoking was identified as the most important co-exposure. Besides taking preventive measure to reduce exposure, the reduction of working hours to 40 h per week is expected to decrease benzene levels below the current TLV.

Abstract
Background Functional constipation (FC) is a pediatric problem that is seen frequently. However, its prevalence in Asia remains undetermined. In this study we attempted to determine the prevalence, risk factors and therapeutic modalities of FC in infants and toddlers in Sri Lanka. Methods Children aged 6.5 months to 4 years were selected from 14 well-baby and vaccination clinics in the Gampaha District of Sri Lanka. A questionnaire with questions regarding the socio-demographic characteristics, child’s bowel habits, psycho-social risk factors and treatment modalities were filled by the mothers. FC was diagnosed according to ROME III criteria. Results A total of 1113 children were analyzed [(female n = 560 (50.3%) with a mean age of 20.7 months, standard deviation [SD] 11.2 months. FC was found in 89 (8.0%). FC was significantly and independently associated with underweight (14.3% vs 7.2%, p = 0.008. [OR and 95% CI: 2,3 (CI; 1.3–4.2)] and residence in an urban area (9.6% vs 5.6%, p = 0.013). [OR and 95% CI: 0.592 (CI; 0.396–0.95)]. Children subjected to violence showed a significantly higher prevalence of FC (20.0 vs 7.8%, p = 0.046). Children being overweight and children living with mothers subjected to violence showed a higher, though not statistically significant, tendency to develop FC. Children with FC visited healthcare clinics more frequently when compared to controls (19.6% vs 6.0%, p < 0.0001). However, only 24% of infants and toddlers with FC were treated specifically for the condition by a doctor. Conclusions FC occurred in 8% of this cohort of Sri Lankan infants and toddlers. It is significantly associated with underweight and living in an urban area. Only a quarter of them received medical attention for their constipation.

Abstract
BACKGROUND Abdominal pain-predominant functional gastrointestinal disorders (AP-FGIDs) are the most common cause of recurrent abdominal pain in children. Despite its high prevalence, the underlying pathophysiology of this condition is poorly understood.
AIM To assess the role of gastric dysmotility and autonomic nervous system dysfunction in the pathophysiology of AP-FGIDs.
METHODS One hundred children, fulfilling Rome III criteria for AP-FGIDs, and 50 healthy controls, aged 5 to 12 years, were recruited after obtaining parental consent. All patients were investigated for underlying organic disorders. Gastric motility and cardiovascular autonomic functions were assessed using validated non-invasive techniques.
RESULTS The main gastric motility parameters assessed (gastric emptying rate [45.7 vs 59.6 in controls], amplitude [48.7 vs 58.2], frequency of antral contractions [8.3 vs 9.4], and antral motility index [4.1 vs 6.4]) were significantly lower in children with AP-FGIDs (P < 0.05). The post-prandial antral dilatation at 1 min after the test meal significantly correlated with the severity of abdominal pain (P < 0.05). Assessment of autonomic functions in AP-FGID patients showed neither a significant difference compared to the control group, nor a correlation with gastric motility abnormalities (P > 0.05). The duration of pain episodes negatively correlated with the parasympathetic tone (maladaptive parasympathetic tone) (P < 0.05).
CONCLUSION Children with AP-FGIDs have abnormal gastric motility but normal cardiovascular autonomic functions. There is no relationship between abnormal gastric motility and autonomic functions. The pathogenesis of AP-FGIDs is not related to cardiovascular autonomic dysfunction.

Abstract
AIM To find the association between asthma and different types of functional abdominal pain disorders (FAPDs) among teenagers.
METHOD
A cross-sectional study was conducted among 13 to 15-year-old children from six randomly selected schools in Anuradhapura district of Sri Lanka. Data were collected using translated and validated self-administered questionnaires (Rome III questionnaire, International Study on Asthma and Allergies in Childhood questionnaire, and Pediatric Quality of Life Inventory 4.0) and administered under an examination setting after obtaining parental consent and assent.
RESULTS Of the 1101 children included in the analysis, 157 (14.3%) had asthma and 101 (9.2%) had at least one FAPDs. Of children with asthma, 19.1% had at least one type of FAPDs. Prevalence rates of functional abdominal pain (FAP) (8.9% vs 3.3% in non-asthmatics), functional dyspepsia (FD) (2.5% vs 0.7%), and abdominal migraine (AM) (3.2% vs 0.4%) were higher in those with asthma (P < 0.05, multiple logistic regression analysis), but not in those with irritable bowel syndrome (4.5% vs 3.1%, P = 0.2). Severe abdominal pain (10.8% vs 4.6%), bloating (16.6% vs 9.6%), nausea (6.4% vs 2.9%), and anorexia (24.2% vs 16.2%) were more prevalent among asthmatics (P < 0.05). Lower gastrointestinal symptoms did not show a significant difference. Scores obtained for health related quality of life (HRQoL) were lower in those with asthma and FAPDs (P < 0.05, unpaired t-test).
CONCLUSION Asthma is associated with three different types of FAPDs, namely, FD, AM, and FAP. HRQoL is significantly impaired in teenagers with asthma and FAPDs.

Abstract
Irritable bowel syndrome (IBS) is a common and troublesome disorder in children with an increasing prevalence noted during the past two decades. It has a significant effect on the lives of affected children and their families and poses a significant burden on healthcare systems. Standard symptom-based criteria for diagnosis of pediatric IBS have changed several times during the past two decades and there are some differences in interpreting symptoms between different cultures. This has posed a problem when using them to diagnose IBS in clinical practice. A number of potential patho-physiological mechanisms have been described, but so far the exact underlying etiology of IBS is unclear. A few potential therapeutic modalities have been tested in children and only a small number of them have shown some benefit. In addition, most of the described patho-physiological mechanisms and treatment options are based on adult studies. These have surfaced as challenges when dealing with pediatric IBS and they need to be overcome for effective management of children with IBS. Recently suggested top-down and bottom-up models help integrating reported patho-physiological mechanisms and will provide an opportunity for better understanding of the diseases process. Treatment trials targeting single treatment modalities are unlikely to have clinically meaningful therapeutic effects on IBS with multiple integrating patho-physiologies. Trials focusing on multiple combined pharmacological and non-pharmacological therapies are likely to yield more benefit. In addition to treatment, in the future, attention should be paid for possible prevention strategies for IBS.

Abstract
Chronic abdominal pain is a common problem in pediatric practice. The majority of cases fulfill the Rome IV criteria for functional abdominal pain disorders (FAPDs). At times, these disorders may lead to rather serious repercussions. Area covered: We have attempted to cover current knowledge on epidemiology, pathophysiology, risk factors related to pathophysiology, clinical evaluation and management of children with FAPDs. Expert commentary: FAPDs are a worldwide problem with a pooled prevalence of 13.5%. There are a number of predisposing factors and pathophysiological mechanisms including stressful events, child maltreatment, visceral hypersensitivity, altered gastrointestinal motility and change in intestinal microbiota. It is possible that the environmental risk factors intricately interact with genes through epigenetic mechanisms to contribute to the pathophysiology. The diagnosis mainly depends on clinical evaluation. Commonly used pharmacological interventions do not play a major role in relieving symptoms. Centrally directed, nonpharmacological interventions such as hypnotherapy and cognitive behavioral therapy have shown both short and long term efficacy in relieving pain in children with FAPDs. However, these interventions are time consuming and need specially trained staff and therefore, not currently available at grass root level. Clinicians and researchers should join hands in searching for more pragmatic and effective therapeutic modalities to improve overall care of children with FAPDs.

Abstract
BACKGROUND Aerophagia is a common childhood functional gastrointestinal disorder. We studied the association between adverse life events (ALEs), psychological maladjustment, somatization, and aerophagia (AP) in adolescents. We also assessed the impact of AP on their health-related quality of life (HRQoL). METHODS A cross-sectional survey was conducted on 2500 subjects of 13-18 years in 8 randomly selected schools in Sri Lanka. Translated, validated, and self-administered questionnaires were used to collect data. Aerophagia was diagnosed using Rome III criteria. KEY RESULTS A total of 2453 questionnaires were analyzed (males 1200 [48.9%], mean age 14.8 years, SD 1.6 years). Of them, 371 adolescents had AP (15.1%). Aerophagia was associated with exposure to physical abuse (20.4% vs. 12.7% in controls, P < .0001), emotional abuse (20.3% vs. 8.2% in controls, P < .0001), and other ALEs (22% vs. 10.2% in controls, P < .001). One hundred and ninety (51.2%) adolescents with AP and 775 (37.2%) controls had a personality score above the international cutoff value of 105, indicating psychological maladjustment (odds ratio 1.77, 95% confidence interval 1.42-2.21, P < .0001). Those with AP had higher somatization (16.4 vs. 8.9) and lower overall HRQoL scores (77.0 vs. 85.1, P < .0001). HRQoL scores of adolescents with AP were lower in all domains, namely, physical (80.6 vs. 86.9), emotional (69.1 vs. 80.3), social (83.8 vs. 90.5), and school (72.6 vs. 82.5) functioning (P < .0001). CONCLUSIONS AND INFERENCES Aerophagia was associated with exposure to ALEs and psychological maladjustment. Affected teenagers suffer from more somatic symptoms and has a poor HRQoL.

Abstract
Background Chronic abdominal pain is a common worldwide problem and known to be associated with psychological problems. This study evaluated the association between abdominal pain-predominant functional gastrointestinal disorders (AP-FGIDs), psychological maladjustment and personality traits in adolescents. Methods Adolescents aged 13–18 years were recruited from 5 randomly selected schools in Ampara district of Sri Lanka. AP-FGIDs were diagnosed using Rome III criteria. Translated and validated Rome III questionnaire (Child report form), personality questionnaire (PAQ) and PedsQL (Pediatric Quality of Life) inventory were used in data collection. Written consent was obtained from a parent and assent was obtained from every child recruited. The questionnaire was distributed in an examination setting to ensure confidentiality and privacy. Research assistants were present during data collection to assist on any necessary clarifications. Results A total of 1697 subjects were recruited [males 779 (45.9%), mean age 15.1 years, SD 1.6 years]. AP-FGIDs were present in 202 (11.9%). Those with AP-FGIDs had significantly higher mean scores for all personality traits (hostility and aggression, negative self-esteem, emotional unresponsiveness, emotional instability and negative world view), except dependency. Affected children had lower scores for all 4 domains of HRQoL (physical, emotional, social and school functioning), compared to controls (p < 0.05). When the cut off value for Sri Lankan children (89) was used, 66.3% with AP-FGIDs and 48.2% controls had PAQ scores within that of psychological maladjustment (p < 0.001). When the international normative value of 105 was used, these percentages were 27.2% and 14.2% respectively (p < 0.0001). The scores obtained for PAQ negatively correlated with scores obtained for HRQoL (r = − 0.52, p < 0.0001). One hundred and seventeen adolescents with AP-FGIDs (57.9%) had sought healthcare for their symptoms. Healthcare consulters had higher PAQ and lower HRQoL scores (p < 0.05). Conclusions Adolescents with AP-FGIDs have more psychological maladjustment and abnormal personality traits than healthy controls. Affected adolescents with higher psychological maladjustments have lower HRQoL. Greater psychological maladjustment and lower HRQoL are associated with healthcare seeking behaviour in adolescents with AP-FGIDs.

Abstract
OBJECTIVES To determine the prevalence and risk factors for functional constipation (FC) in adolescent Nigerians. METHOD A cross-sectional study was conducted in rural and urban areas of two states in the southern part of Nigeria. Adolescents aged 10-18 years were recruited from 11 secondary schools, using a stratified random sampling technique. A validated self-administered questionnaire on Rome III criteria for diagnosing FC and its predisposing factors was filled by each participant in a classroom setting. RESULTS A total of 874 questionnaires was distributed and 818 (93%) properly filled questionnaires were included in the analysis. The mean age of the participants was 14.6±2.0 years with 409 (50%) being boys. FC was present in 223 (27%) with no difference in prevalence between sexes. Prevalence of FC was 29% in urban areas and 26% in rural areas (p>0.05). The condition was significantly associated with low social class (p=0.013). Exposure to stressful life events at home and school did not predispose the participants to develop FC. CONCLUSIONS FC is a significant health problem among adolescent Nigerians. The condition is associated with low social class.

Abstract
OBJECTIVES To assess psychological maladjustment in adolescents with functional constipation. STUDY DESIGN We conducted a cross-sectional survey in five schools. Adolescents aged between 13 and 18 years were included in the study. Validated questionnaires were used to collect bowel habits and demographic data, health-related quality of life (HRQoL) and psychological maladjustment. Rome III criteria were used to diagnose constipation. RESULTS 1697 adolescents were recruited (boys 779 (45.9%), mean age 15.06 years and SD 1.6 years). Prevalence of constipation was 6.7%, of whom 52 were boys (45.6%) and 62 were girls (54.4%). 38 adolescents (33.3%) with constipation and 230 controls (14.5%) had significant psychological maladjustment. Among seven different personality dimensions used to assess psychological maladjustment, children with constipation had significantly more deficits than controls in hostility and aggression (14.2 vs 12.6 in controls (mean difference 1.54, 95% CI (0.89 to 2.19) p<0.001), negative self-esteem (12.0 vs 10.5 in controls, mean difference 1.54 95% CI (0.96 to 2.06) p<0.001), negative self-adequacy (11.9 vs 9.8 controls, mean difference 2.07 95% CI (1.46 to 2.67) p<0.001), emotional unresponsiveness (12.9 vs 11.5 controls, mean difference 1.44 95% CI (0.84 to 2.04) p<0.001), emotional instability (17.1 vs 15.6, mean difference 1.53 95% CI (0.86 to 2.2) p<0.001) and negative world view (12.1 vs 10.2 controls, mean difference 1.91 95% CI (1.24 to 2.59) p<0.001). The total HRQoL of adolescents with constipation was lower than controls (70.6 vs 79.0 mean difference 9.48 95% CI (1.4 to 6.7) p<0.05). CONCLUSION A significant proportion of children with constipation are suffering from psychological maladjustment.

Abstract
Functional constipation (FC) is a significant health problem in children and contrary to common belief, has serious ramifications on the lives of children and their families. It is defined by the Rome criteria which encourage the use of multiple clinical features for diagnosis. FC in children has a high prevalence (0.7%-29%) worldwide, both in developed and developing countries. Biopsychosocial risk factors such as psychological stress, poor dietary habits, obesity and child maltreatment are commonly identified predisposing factors for FC. FC poses a significant healthcare burden on the already overstretched health budgets of many countries in terms of out-patient care, in-patient care, expenditure for investigations and prescriptions. Complications are common and range from minor psychological disturbances, to lower health-related quality of life. FC in children also has a significant impact on families. Many paediatric clinical trials have poor methodological quality, and drugs proved to be useful in adults, are not effective in relieving symptoms in children. A significant proportion of inadequately treated children have similar symptoms as adults. These factors show that constipation is an increasing public health problem across the world with a significant medical, social and economic impact. This article highlights the potential public health impact of FC and the possibility of overcoming this problem by concentrating on modifiable risk factors rather than expending resources on high cost investigations and therapeutic modalities.

Abstract
Background Approximately 0.2–1 % of children suffers from abdominal migraine (AM). Pathophysiology of AM has not been adequately studied. This study evaluated gastric motility in children with AM. Methods Seventeen children (6 boys), within an age range of 4–15 years, referred to a tertiary care paediatric unit, North Colombo Teaching Hospital Ragama, Sri Lanka, from 2007 to 2012, were screened. Those fulfilling Rome III criteria for AM were recruited after obtaining parental consent. None had clinical or laboratory evidence of organic disorders. Twenty healthy children (8 boys), with an age range of 4–14 years, were recruited as controls. Liquid gastric emptying rate (GE) and antral motility parameters were assessed using an ultrasound method. Results Average GE (41.6 % vs. 66.2 %, in controls), amplitude of antral contractions (A) (57.9 % vs. 89.0 %) and antral motility index (MI) (5.0 vs. 8.3) were lower and fasting antral area (1.8 cm2 vs. 0.6 cm2) was higher in children with AM (p < 0.01). No significant difference in the frequency of antral contractions (F) (8.8/3 min vs. 9.3/3 min, p = 0.08) was found between the two groups. Scores obtained for severity of abdominal pain had a negative correlation with A (r = −0.55, p = 0.03). Average duration of abdominal pain episodes correlated with GE (r = −0.58, p = 0.02). Negative correlations were observed between duration of AM and A (r = −0.55), F (r = −0.52), and MI (r = −0.57) (p < 0.05). Conclusions GE and antral motility parameters were significantly lower in children with AM. A significant correlation was found between symptoms and gastric motility. These findings suggest a possible role of abnormal gastric motility in the pathogenesis of AM.

Abstract
Chronic abdominal pain is one of the most common clinical syndromes encountered in day to day clinical paediatric practice. Although common, its definition is confusing, predisposing factors are poorly understood and the pathophysiological mechanisms are not clear. The prevailing viewpoint in the pathogenesis involves the inter-relationship between changes in hypersensitivity and altered motility, to which several risk factors have been linked. Making a diagnosis of functional abdominal pain can be a challenge, as it is unclear which further diagnostic tests are necessary to exclude an organic cause. Moreover, large, well-performed, high-quality clinical trials for effective agents are lacking, which undermines evidence-based treatment. This Review summarizes current knowledge regarding the epidemiology, pathophysiology, risk factors and diagnostic work-up of functional abdominal pain. Finally, management options for children with functional abdominal pain are discussed including medications, dietary interventions, probiotics and psychological and complementary therapies, to improve understanding and to maximize the quality of care for children with this condition.

Abstract
Abdominal pain-predominant functional gastrointestinal diseases (AP-FGD) are common in children and commonly attributed to exposure to child abuse. However, this relationship has not been studied in teenagers, and the main objective of the current study was to assess it. Teenagers were recruited from four randomly selected schools in Western province of Sri Lanka. Data were collected using a validated self-administered questionnaire. AP-FGD were diagnosed using Rome III criteria. A total of 1850 teenagers aged 13-18 years were included. Three hundred and five (16.5%) had AP-FGD. AP-FGD were significantly higher in those exposed to sexual (34.0%), emotional (25.0%) and physical (20.2%) abuse, than in those not abused (13.0%, p < 0.001). Those with AP-FGD exposed to abuse had a higher severity score for bowel symptoms (30.8% vs. 24.7% in not abused, p < 0.05). This study highlights the importance of identifying exposure to abuse in management of teenagers with AP-FGD.

Abstract
Background Abdominal pain predominant functional gastrointestinal diseases (AP-FGD) are commonly seen in the paediatric age group. It has significant impact on daily activities of affected children. Main objective of this study was to assess the health related quality of life (HRQoL) in children with AP-FGD. Method This was a cross sectional survey conducted in children aged 13–18 years, in four randomly selected schools in Western province of Sri Lanka. Data was collected using a previously validated, self-administered questionnaire. It had questions on symptoms, HRQoL and health care consultation. AP-FGD were diagnosed using Rome III criteria. Results A total of 1850 questionnaires were included in the analysis [males 1000 (54.1%), mean age 14.4 years and SD 1.3 years]. Of them, 305 (16.5%) had AP-FGD [irritable bowel syndrome = 91(4.9%), functional dyspepsia = 11 (0.6%), abdominal migraine = 37 (1.9%) and functional abdominal pain = 180 (9.7%)]. Lower HRQoL scores for physical (83.6 vs. 91.4 in controls), social (85.0 vs. 92.7), emotional (73.6 vs. 82.7) and school (75.0 vs. 82.5) functioning domains, and lower overall scores (79.6 vs. 88.0) were seen in children with AP-FGD (p < 0.001). A weak but significant negative correlation was observed between HRQoL score and severity of abdominal pain (r = −0.24, p < 0.0001). Eighty five children (27.9%) had sought healthcare for AP-FGD. Factors determining healthcare seeking were presence of abdominal bloating and vomiting (p < 0.05). Conclusions Children with AP-FGD have lower quality of life in all 4 domains. Those with severe symptoms have lower HRQoL. Approximately 28% of children with AP-FGD seek healthcare for their symptoms.

Abstract
OBJECTIVE To assess the health related quality of life (HRQoL) and somatization in school children with constipation. STUDY DESIGN This cross-sectional survey was conducted in children aged 13-18 years, in 4 schools in Gampaha district of Sri Lanka. Data were collected using a pretested, self-administered questionnaire with questions on bowel habits, somatization, and HRQoL. Constipation was diagnosed using Rome III criteria. RESULTS A total of 1792 children were included in the analysis (males 975 [54.4%], mean age 14.4 and SD 1.3 years). One hundred thirty-eight (7.7%) fulfilled Rome criteria for constipation. Children with constipation had lower HRQoL scores for physical (83.6 vs 91.4 in controls, P < .0001), social (85.0 vs 92.7, P = .0001), emotional (73.6 vs 82.7, P =.0001), school functioning (75.0 vs 82.5, P < .0001), and lower overall scores (79.6 vs 88.0, P = .0001). HRQoL scores were lower in those with fecal incontinence and constipation compared with constipation alone (70.0 vs 81.1, P = .004). Patient perceived severity of abdominal pain (r = -0.22, P = .01) and severity of bowel symptoms (r = -0.22, P = .01) showed significant negative correlation with total HRQoL scores. Total somatization score also found to be negatively correlated (r = -0.47, P < .0001) with HRQoL. CONCLUSIONS Children with constipation have lower HRQoL scores than controls in physical, social, emotional, and school functioning. They also have a wide range of somatic symptoms. These issues need to be addressed during clinical evaluation of children with constipation to understand the impact of the disease on the life of affected children and to provide optimal care.

Abstract
BACKGROUND AND AIMS Functional dyspepsia (FD) is an important gastrointestinal problem with obscure etiology. Abnormal gastric motility is suggested as a possible pathophysiological mechanism for symptoms. The main objective of this study was to assess gastric motility in Sri Lankan children with FD. METHODS Forty-one children (19 [46.3%] males, age 4-14 years, mean 7.5 years, SD 2.6 years) referred to the Gastroenterology Research Laboratory, Faculty of Medicine, University of Kelaniya, from January 2007 to December 2011, were screened. Those fulfilling Rome III criteria for FD were recruited. None had clinical or laboratory evidence of organic disorders. Twenty healthy children were recruited as controls (eight [40%] males, age 4-14 years, mean 8.4 years, SD 3.0 years). Liquid gastric emptying rate (GE) and antral motility parameters were assessed using an ultrasound-based method. RESULTS Average GE (45.6% vs 66.2% in controls), amplitude of antral contractions (58.2% vs 89.0%) and antral motility index (5.1 vs 8.3) were lower and fasting antral area (1.5 cm(2) vs 0.6 cm(2)) was higher in patients with FD (P < 0.01). Frequency of antral contractions (8.8 vs 9.3) did not show a significant difference (P = 0.07). Scores obtained for severity of abdominal pain negatively correlated with GE (r = -0.35, P = 0.025). Children with FD, exposed to stressful events had higher fasting antral area (1.9 cm(2)) than those not exposed to stress (1.0 cm(2)) (P = 0.02). CONCLUSIONS GE and antral motility parameters were significantly impaired in children with FD compared with controls. GE negatively correlated with severity of symptoms. This study points to disturbances in gastric motility as an etiological factor for FD.

Abstract
BACKGROUND Faecal incontinence (FI) in children is a significant gastrointestinal problem, with great personal and social impacts. It is characterised by recurrent loss of faecal matter into the underwear. Both functional and organic causes contribute to its aetiology with the former predominating. AIM To review the epidemiology, pathophysiology, clinical evaluation and management of functional faecal incontinence in children. METHODS A PubMed search was conducted using search terms f(a)ecal incontinence, and encopresis. Articles on epidemiology, pathophysiology, clinical evaluation, investigation and management of functional FI in children were retrieved and assessed. RESULTS Community prevalence of this distressing problem ranges from 0.8% to 7.8% globally. Male: female ratio varies from 3:1 to 6:1. The diagnosis of FI is often based on established clinical criteria. The majority (82%) have constipation associated functional FI. Biopsychosocial factors play a crucial role in the pathogenesis. Limited physiological testing of anorectal function is recommended in the diagnostic procedures, particularly in children with atypical symptoms and possible organic disorders. Management of FI needs a multidisciplinary approach which includes establishment of an effective doctor-patient partnership, understanding the underlying mechanisms, pharmacotherapy and behavioural treatment. Approximately 15% of children with functional nonretentive faecal incontinence (FNRFI) had the same symptoms at the age of 18 years. CONCLUSION Significant therapeutic advances have been made for retentive faecal incontinence, but treatment options for functional nonretentive faecal incontinence are limited. Limited long-term outcome data show that the majority outgrow faecal incontinence. A substantial proportion of children progress to adulthood with faecal incontinence.

Abstract
BACKGROUND Rumination syndrome (RS) is a functional gastrointestinal disorder (FGD) increasingly recognized in children and adolescents. The epidemiology of this condition in school aged children is poorly understood. The main objective of this study was to assess the prevalence of rumination and other related associations in a cohort of Sri Lankan children. METHODS Children aged 10-16 years were randomly selected from 8 schools in 4 provinces in Sri Lanka. RS was diagnosed using Rome III criteria. Data was collected using a self administered questionnaire distributed in an examination setting. It was translated into Sinhala, the native language and pretested before distribution. RESULTS A total of 2163 children were included in the study (55% boys, mean age 13.4 years, SD 1.8 years). Prevalence of RS was 5.1% (n = 110); boys 5.1% and girls 5.0%. When symptoms were analyzed, 73.6% reported re-swallowing of regurgitated food, while the rest spat it out. In 94.5% regurgitation occurred during the first hour after the meal. Only 8.2% had daily symptoms while 62.7% had symptoms weekly. Abdominal pain, bloating and weight loss were the commonest symptoms associated with RS (19.1%, 17.3% and 11.8% respectively). No significant association was observed between exposure to stressful events and rumination (p > 0.05). Twenty (18.2%) with RS fulfilled Rome III criteria for at least one other FGD. School absenteeism was seen in 11.8% of affected children. CONCLUSION RS was reasonably common in this cohort of school-aged children and adolescents in Sri Lanka. However, symptoms were severe enough to affect schooling only in 12% of affected children. Around one fifth with RS had at least one other overlapping FGD.

Abstract
This island-wide cross-sectional survey was conducted to assess the healthcare consultations in Sri Lankan children with constipation. Children aged 10-16 years were randomly selected from five randomly selected schools in three randomly selected provinces of Sri Lanka. Data were collected using a pre-tested questionnaire based on Rome III criteria. Of the 2770 questionnaires distributed, 2694 (97.3%) properly filled questionnaires were included in the analysis. From 416 (15.4%) children with chronic constipation, only 16 (3.8%) had sought medical advice during the previous 12 months. Younger children and those with a similar family history were more likely to seek healthcare. The majority of children with symptoms indicating severe constipation such as painful defecation, large volume stool, faecal incontinence and blood stained stools had not sought medical help for their symptoms. Parents should pay more attention to bowel habits of their children to identify and treat constipation early to prevent complications.

Abstract
BACKGROUND Gastric sensorymotor dysfunctions have been implicated in the pathophysiology of some functional gastrointestinal disorders, such as functional dyspepsia and irritable bowel syndrome. Therefore, we hypothesized that abnormal gastric emptying and impaired antral motility are possible underlying mechanisms of symptoms in children with functional abdominal pain (FAP). METHODS Hundred and two children [37 (36.3%) males, 4-14 years, mean 7.8 years, SD 2.7 years] fulfilling Rome III criteria for FAP were recruited for this study. An age and sex compatible group of healthy children (n = 20) were selected as controls [8 (40%) males, 4-14 years, mean 8.4 years, SD 3.0 years]. Liquid gastric emptying rate (GER) and antral motility parameters (amplitude of antral contractions, frequency of antral contractions and antral motility index) were assessed using a previously reported ultrasound method. KEY RESULTS Average GER (42.1% vs 66.2% in controls), amplitude of antral contractions (56.5% vs 89%), frequency of contractions per 3 min (8.5 vs 9.3), and antral motility index (4.9 vs 8.3) were significantly lower in patients with FAP compared with controls (P < 0.01). Fasting antral area was higher in patients (1.4 vs 0.6, P < 0.0001). GER negatively correlated with the scores obtained for severity of abdominal pain (r = -0.29, P = 0.004). CONCLUSIONS & INFERENCES Gastric emptying rate and antral motility parameters were significantly impaired in patients with FAP and GER negatively correlated with symptom severity. These findings highlight the possible role of gastrointestinal motility abnormalities in the pathophysiology of childhood FAP.

Abstract
Constipation is a common paediatric problem, but its prevalence in Asia is unknown. A cross-sectional survey using a previously validated, self-administered questionnaire was conducted in randomly selected children aged 10-16 years, in five randomly selected schools in Sri Lanka. Two schools were in Eastern Province, which has been affected by the separatist war. Constipation was defined using Rome III criteria. Of 2694 children included in the analysis, 416 (15.4%) had constipation. Symptoms independently associated with constipation were straining (71.6% vs 28.4% of controls), bleeding per rectum (14.2% vs 2.2%) and abdominal pain (55% vs 35.2%). The prevalence of constipation was significantly higher in those with a family history of constipation (49% vs 14.8%), living in a war affected area (18.1% vs 13.7%) and attending an urban school (16.7% vs 13.3%). In conclusion, chronic constipation is a significant problem affecting 15% of Sri Lankan school children and adolescents.

Abstract
Constipation is a common childhood disease. It is associated with exposure to stressful events. Sri Lanka was involved in three decades of civil war causing significant emotional stress. This study assessed the prevalence of childhood constipation during and after war. Data were collected from 10- to 16-year olds in five randomly selected schools, in three provinces (two schools from Eastern province), using a validated, self-administered questionnaire. Constipation was diagnosed using Rome III criteria. Phase I was conducted during the war to liberate Eastern province from separatist groups. Phase II was conducted 2 years after the war in same schools. During Phase I, prevalence of constipation was significantly higher in Eastern province (18.1%) compared with Western (14.2%) and Southern (12.6%) provinces (p = 0.009). Constipation was significantly lower in Eastern province in Phase II (10%) compared with Phase I (p < 0.0001). This study highlights the possible link between devastating emotional effects of civil war and childhood constipation.

Abstract
Little is known about the prevalence of functional gastrointestinal diseases (FGDs) in adolescents, especially in developing countries. This cross-sectional survey conducted in a semi-urban school in Sri Lanka, assessed the prevalence of whole spectrum of FGDs in 427 adolescents (age 12-16 years) using a validated self-administered questionnaire. According to Rome III criteria, 123 (28.8%) adolescents had FGDs. Of them, 59 (13.8%) had abdominal-pain-related FGDs [irritable bowel syndrome (IBS) 30, functional dyspepsia 15, functional abdominal pain 13 and abdominal migraine 1]. Prevalence of functional constipation, aerophagia, adolescent rumination syndrome, cyclical vomiting syndrome and non-retentive faecal incontinence were 4.2, 6.3, 4, 0.5 and 0.2%, respectively. Only 58 (13.6%) adolescents were found to have FGDs when Rome II criteria were used. In conclusion, FGDs were present in more than one-fourth of adolescents in the study group, of which IBS was the most common. Rome III criteria were able to diagnose FGDs more comprehensively than Rome II.

Abstract
Constipation in children is a common health problem affecting 0.7% to 29.6% children across the world. Exact etiology for developing symptoms is not clear in children and the majority is considered to have functional constipation. Alteration of rectal and pelvic floor function through the brain-gut axis seems to play a crucial role in the etiology. The diagnosis is often a symptom-based clinical process. Recently developed Rome III diagnostic criteria looks promising, both in clinical and research fields. Laboratory investigations such as barium enema, colonoscopy, anorectal manometry and colonic transit studies are rarely indicated except in those who do not respond to standard management. Treatment of childhood constipation involves several facets including education and demystification, toilet training, rational use of laxatives for disimpaction and maintenance and regular follow-up. Surgical options should be considered only when medical therapy fails in long standing constipation. Since most of the management strategies of childhood constipation are not evidence-based, high-quality randomized controlled trials are required to assess the efficacy of currently available or newly emerging therapeutic options. Contrary to the common belief that children outgrow constipation as they grow up, a sizable percentage continue to have symptoms beyond puberty.

Abstract
Emotional stress is associated with some functional gastrointestinal diseases, but its role in aetiology of functional constipation is unclear. This island-wide, questionnaire-based, cross-sectional survey was conducted to assess the association between constipation and emotional stress, in 10-16-year-olds. Constipation was defined using Rome III criteria. Out of 2699 children included in the analysis, 416 (15.4%) had constipation. Constipation was higher in those exposed to stressful events (odds ratio 2.52, p < 0.0001). Separation from the best friend, failure in an examination, severe illness of a family member, loss of job by a parent, frequent punishment by parents and living in an area affected by separatist war remained independently associated with constipation (p < 0.05). In conclusion, constipation was significantly higher in children exposed to stressful life events. Modulation of gut motility through brain-gut axis probably alters colonic transit and ano-rectal functions, causing constipation.

Abstract
OBJECTIVE To evaluate the timing, causes and distribution of neonatal deaths in Sri Lanka, to provide information for policy makers, to undertake appropriate measures to achieve the Millennium Development Goals. METHODS All neonatal deaths, reported to the Registrar General's Office, Sri Lanka, from 1997 to 2001, were included in the analysis. RESULTS During this 5-year period, 17,946 neonatal deaths have occurred, of them 90.5% have occurred during the first week of life. The leading causes were preterm deliveries (33.2%), infections (19.8%) and cardiac anomalies (17.4%). The neonatal mortality rates (NMR) were higher in districts with specialised neonatal care facilities and high concentration of estates. CONCLUSIONS Approximately 3600 neonates die in Sri Lanka annually, even though it has a lower NMR compared to rest of the South Asia. Neonatal deaths were higher in the major cities and in the estate sector. The majority of neonatal deaths were due to complications of preterm birth, neonatal sepsis and cardiac anomalies.

Abstract
CONTEXT Recurrent abdominal pain is one of the commonest gastrointestinal complaints in children, affecting approximately 10% of school aged children and adolescents. There is no consensus with regards to etiology, investigation and management of this common problem. This review addresses some of the issues related to epidemiology, etiology, management and prognosis of recurrent abdominal pain. EVIDENCE ACQUISITION We reviewed current literature on this broad subject, specially concentrating on epidemiology, etiology and, basic and advanced management strategies, from 1958 to date, using PubMed, Embase, Cochrane database and cross references. RESULTS The majority of the affected children have functional gastrointestinal diseases. The exact cause of pain remains obscure. New evidence suggests that emotional stress, visceral hypersensitivity and gastrointestinal motility disorders may play a vital part in its origin. Pharmacological treatments are commonly used in an effort to manage symptoms, despite the lack of data supporting their efficacy. CONCLUSIONS Most children with recurrent abdominal pain have functional gastrointestinal diseases and a detailed history, examination and basic stool, urine and hematological investigations are sufficient to exclude organic pathology in them. Despite the magnitude of the problem, knowledge on the effective management options is poor.

Abstract
Recurrent abdominal pain (RAP) is a common problem among children and adolescents. The epidemiology of RAP among Sri Lankan children is unknown. A self-administered parental questionnaire was distributed to 810 randomly selected school children, aged 5-15 years, and 734 (90.6%) were returned. RAP was diagnosed using Apley criteria. Children who fulfilled the criteria were interviewed. Seventy-seven had RAP (10.5%). Of them, 45 (58.4%) had periumbilical pain. The severity was mild to moderate in 45 (58.4%) and severe in 32 (41.6%). Common associated symptoms were headache (42.9%), anorexia (35.1%), lethargy (23.4%) and joint pain (23.4%). Health care consultation among affected children was 70.1%. RAP was significantly higher in those who were exposed to stressful life events and who had a family history of RAP (p < 0.0001). RAP was not associated with school academic performance and participation in sports (p > 0.05). According to our results, the epidemiology and clinical profile of RAP in Sri Lankan children appears to be similar to that in other parts of the world, except for health care consultation, which is higher than previously reported.
