Item Defecation disorders in children: Constipation and fecal incontinence(Springer International, 2021) Baaleman, D.F.; Rajindrajith, S.; Devanarayana, N.M.; Lorenzo, C.D.; Benninga, M.A.Defecation disorders denote a state of altered defecation dynamics leading to an array of clinical presentations. With the currently available epidemiological studies, it is evident that these disorders have become widely spread global health problems. Due to the broadening of the understanding of escalating healthcare costs and poor quality of life, these disorders demand attention of clinicians and researchers, more than at any other time in history. However, it is regrettable that only little guidance is available for healthcare professionals to manage these disorders. Most of the therapeutic trials and investigation plans are archaic from the viewpoint of a twenty-first-century clinician and are not evidence based. However, new research ventures are being carried out, and the horizon of the knowledge base is expanding, perhaps indicating a brighter future. In this chapter, we discuss emerging concepts of definitions, epidemiology, pathophysiology, clinical evaluation, and management of defecation disorders in children and adolescents.Item Research in pediatrics(Samudra Medical Publications, 2022) Mettananda, S.; Rajindrajith, S.No abstract availableItem Rheumatology(Samudra Medical Publications, 2022) Rajindrajith, S.; Mettananda, S.No abstract availableItem Item Pediatric emergencies(Samudra Medical Publications, 2022) Perera, P.; Rajindrajith, S.No abstract availableItem Concise textbook of pediatrics(Samudra Medical Publications, 2022) Rajindrajith, S.; Mettananda, S.; Abeyagunawardena, A.No abstract availableItem Neurogastroenterology and motility disorders in pediatric population(Elsevier, 2019) Rajindrajith, S.; Devanarayana, N.M.; Chanpong, A.; Thapar, N.Motility of the gastrointestinal tract plays a critical role in the maintenance of its many physiological functions. These motility patterns, which vary along the gastrointestinal tract, are achieved by highly coordinated interactions between the neuromusculature of the gut (smooth muscle layers, enteric nervous system, interstitial cells of Cajal), central nervous system, autonomic nervous system, hormones, peptides and the microbiome. Other external factors such as diet, and age related changes in the gastrointestinal tract also, ultimately, affect gastrointestinal motility. A subtle change in any of the above factors could significantly impact on gastrointestinal function leading to pediatric gastrointestinal motility disorders. Here, we review common motility disorders in children and provide an indepth understanding of the pathophysiology and management of these problem. © 2020 Elsevier Inc.

FGIDs consist of a group of chronic gastrointestinal problems characterised by recurrent symptoms that cannot be explained by structural and biochemical abnormalities. The chronic and disabling nature of symptoms and their remarkably high prevalence across the globe has identified them as a concern for paediatric public health. Several studies have shown a significant percentage of children with non-organic recurrent abdominal pain to have functional gastrointestinal diseases. Aerophagia is a functional gastrointestinal disease characterised by repetitive swallowing of air that leads to abdominal distension, excessive belching and/or flatus. Cyclical vomiting syndrome is a clinical entity associated with recurrent episodes of severe nausea and vomiting that may last for hours to days with well-demarcated symptom-free intervals. Functional constipation is a cosmopolitan problem and with prevalence rates varying by geographical location and environmental cons.Item Clinical evaluation of children with constipation: history and physical examination(Nova Science Publishers Inc, 2013) Rajindrajith, S.; Devanarayana, N.M.; Benninga, M.A.Item Defecation Disorders in Children: epidemiology and risk factors(Author Publication, 2015) Rajindrajith, S.
