Download or read book Colonic Motility written by Sushil K. Sarna and published by Biota Publishing. This book was released on 2010-11-01 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three distinct types of contractions perform colonic motility functions. Rhythmic phasic contractions (RPCs) cause slow net distal propulsion with extensive mixing/turning over. Infrequently occurring giant migrating contractions (GMCs) produce mass movements. Tonic contractions aid RPCs in their motor function. The spatiotemporal patterns of these contractions differ markedly. The amplitude and distance of propagation of a GMC are several-fold larger than those of an RPC. The enteric neurons and smooth muscle cells are the core regulators of all three types of contractions. The regulation of contractions by these mechanisms is modifiable by extrinsic factors: CNS, autonomic neurons, hormones, inflammatory mediators, and stress mediators. Only the GMCs produce descending inhibition, which accommodates the large bolus being propelled without increasing muscle tone. The strong compression of the colon wall generates afferent signals that are below nociceptive threshold in healthy subjects. However, these signals become nociceptive; if the amplitudes of GMCs increase, afferent nerves become hypersensitive, or descending inhibition is impaired. The GMCs also provide the force for rapid propulsion of feces and descending inhibition to relax the internal anal sphincter during defecation. The dysregulation of GMCs is a major factor in colonic motility disorders: irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and diverticular disease (DD). Frequent mass movements by GMCs cause diarrhea in diarrhea predominant IBS, IBD, and DD, while a decrease in the frequency of GMCs causes constipation. The GMCs generate the afferent signals for intermittent short-lived episodes of abdominal cramping in these disorders. Epigenetic dysregulation due to adverse events in early life is one of the major factors in generating the symptoms of IBS in adulthood.

Download or read book Anorectal Physiology written by Lucia Camara Castro Oliveira and published by Springer Nature. This book was released on 2020-08-11 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first comprehensive book exclusively dedicated to anorectal physiology and the importance of diagnostic tools in guiding the evaluation and treatment of anorectal dysfunction. Functional disorders, and specifically fecal incontinence and evacuatory disorders, are prevalent in the general population, affecting up to 20% of individuals. As many of these conditions have extremely complex mechanisms, a thorough understanding of anorectal physiology is a crucial element in the surgeon’s “arsenal" to ensure accurate evaluation and to inform treatment. At this time, there is no other title that specifically addresses all aspects of anorectal physiology, as well as anorectal and pelvic floor disorders, including fecal incontinence and defecation disorders. Specifically, the book provides detailed descriptions of diagnostic methods and treatment algorithms for a range of anorectal conditions, including modern treatment modalities such as sacral neuromodulation. A unique and comprehensive reference covering all aspects of the evaluation and treatment of anorectal disorders, Anorectal Physiology – A Clinical and Surgical Perspective will be of significant interest to proctologists and coloproctologists, gastroenterologists, colorectal surgeons, gynecologists and all other professionals interested in anorectal physiology.

Download or read book Where India Goes written by Diane Coffey and published by Harper Collins. This book was released on 2017-07-10 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than half the people who defecate in the open live in India. Around the world, people live healthier lives than in centuries past, in part because latrines keep faecal germs away from growing babies. India is an exception. Most Indians do not use toilets or latrines, and so infants in India are more likely to die than in neighbouring poorer countries. Children in India are more likely to be stunted than children in sub-Saharan Africa.Where India Goes demonstrates that open defecation in India is not the result of poverty but a direct consequence of the caste system, untouchability and ritual purity. Coffey and Spears tell an unsanitized story of an unsanitary subject, with characters spanning the worlds of mothers and babies living in villages to local government implementers, senior government policymakers and international development professionals. They write of increased funding and ever more unused latrines.Where India Goes is an important and timely book that calls for the annihilation of caste and attendant prejudices, and a fundamental shift in policy perspectives to effect a crucial, much overdue change.
