These protocols should address aspects of triage and multidisciplinary care including access to a therapeutic endoscopist skilled in endoscopic hemostasis and trained support to assist with urgent endoscopy purchase 120mg sildalis mastercard. Despite remarkable advances in medical and endoscopic therapy generic 120 mg sildalis free shipping, non-variceal upper gastrointestinal hemorrhage continues to impose a significant disease burden buy sildalis 120mg with amex. Introduction The term gastritis has been used variously and incorrectly to describe symptoms referable to the upper gastrointestinal tract safe 120 mg sildalis, the macroscopic appearances of inflammation or injury in the stomach at endoscopy and the histologic features of inflam- mation or injury to the gastric mucosa at microscopy. Unfortunately, there is a very poor correlation between an individuals symptoms and any abnormalities evident at endoscopy or microscopy. Only the histological features compatible with inflammation may be correctly used with the term gastritis, which will be the subject of the present chapter (Table 1). Indeed, it has been proposed that an endoscopy performed without mucosal biopsies is an incomplete examination. In addition to specific lesions or abnormalities, biopsies should also be taken from the antrum (2 biopsies) and body of the stomach (2 biopsies) and some authors also recommend a fifth biopsy from the gastric angulus or incisura to identify possible H. However, even a chemical gastropathy may be accompanied by inflammation and both entities will, therefore, be addressed. Acute gastritis is characterized by an inflammatory infiltrate that is pre- dominantly neutrophilic and is usually transient in nature. Acute gastritis may cause epigastric pain, nausea and vomiting but it may also be completely asymptomatic. Chronic gastritis is characterized by an infiltrate of lymphocytes, plasma cells, or both, that may also be associated with intestinal metaplasia and atro- phy of the epithelium. In intestinal metaplasia, the normal gastric epithelium is replaced by metaplastic columnar absorptive cells and goblet cells; these are usually small-intestinal in morphology although features of a colonic epithelium may be present. The development of atrophic gastritis and intesti- nal metaplasia is considered to be premalignant although the incidence of gastric cancer in gastric intestinal metaplasia is unknown and surveillance is not widely practised. In the Western world, histologic changes of chronic gas- tritis occur in up to 50% of the population in later life although the incidence of gastric cancer is falling, almost certainly due to the decreasing prevalence of H. Chronic gastritis rarely causes symptoms although it can be associated with nausea, vomiting and upper abdominal discomfort. Shaffer 143 In addition to elements of chronicity, gastritis can also be categorized on the basis of identifiable etiology (e. There are numerous causes of histologically diagnosed gastritis, and the importance of knowing the cause of the gastritis is to treat the underlying condition. It must be stressed that even when the cause of the gastritis is treated, such as in the person withy dyspepsia and a chronic H. The characteristic histo- logical finding is owl-eye, intranuclear inclusions in cells of the mucosal epithelium, vascular endothelium and connective tissue. At endoscopy, the gastric mucosa has a cobblestone appearance due to multiple superficial linear ulcers and small raised ulcerated plaques, while histology shows numerous cells with ground-glass nuclei and eosinophilic, intranuclear inclusion bodies surrounded by halos. Over time, the initial antral-predominant gastritis progresses to a pangastri- tis and then to atrophic gastritis and intestinal metaplasia precursors to the development of gastric cancer (the Correa hypothesis). Phlegmonous (suppurative) gastritis is a rare bacterial infection of the submucosa and muscularis propria and is associated with massive alcohol ingestion, upper respiratory tract infection, and immune compromise; it has a mortality rate in excess of 50%. Emphysematous gastritis, due to Clostridium welchii, may lead to the formation of gas bubbles, along the gastric contour on x-ray. Treatment requires gastric resection or drainage and high-dose systemic antibiotics. Mycobacterium tuberculosis gastritis is rare; ulcers, masses, or gastric outlet obstruction may be seen at endoscopy and biopsies show necrotizing granulomas with acid-fast bacilli. Mycobacterium avium complex gastritis is very rare, even in immunocompromised individuals; gastric mucosal biopsies show foamy histiocytes containing acid-fast bacilli. In actinomycosis, endoscopy may reveal appearances suggestive of a gastric malignancy; biopsies show multiple abscesses containing Actinomyces israelii, a gram-positive filamentous anaerobic bacterium. Parasitic causes of gastri- tis include Cryptosporidia, Strongyloides stercoralis, Anisakis (from raw marine fish), Ascaris lumbricoides and Necator americanus (hookworm). Endoscopic findings are non-specific and histology shows cell necrosis (apoptotic bodies intraepithelial vacuoles containing karyorrhectic debris and fragments of cytoplasm) in the neck region of the gastric mucosa. It is associated with other autoimmune disorders such as Hashimotos thyroiditis and Addisons disease. Mucosal atrophy, with loss of parietal cells, leads to decreased production of acid and intrinsic factor; about 10% of these patients develop low serum vitamin B12 levels and pernicious anemia. Chemical Gastropathy (Reactive Gastropathy) A number of different agents can produce gastric mucosal injury, characterized at endoscopy by hemorrhagic lesions and erosions (necrosis to the level of the muscularis mucosa) or ulcers (necrosis extending deeper than the muscularis mucosa). Portal hyper- tension produces a congestive gastropathy, with vascular ectasia but, again, only a minimal inflammatory infiltrate. Crohn disease of the stomach is uncommon, particularly in the absence of disease elsewhere in the gastrointestinal tract. Endoscopy may show mucosal reddening and nodules with or without overlying erosions and ulcers that may be elongated or serpiginous. Histological features include non-caseating granu- lomata, ulceration, chronic inflammation and submucosal fibrosis. Sarcoidosis of the stomach can be difficult to distinguish endoscopically and histologically from Crohn disease and the diagnosis must be based on the presence of other systemic features. Gastritis with Specific Diagnostic Features Collagenous gastritis has been reported in association with collagenous colitis and lymphocytic colitis; it is very rare. At endoscopy, non-specific findings include mucosal hemorrhages, erosions and nodularity while histology shows a chronic gastritis (plasma cells and intra-epithelial lymphocytes), focal atrophy and focal collagen deposition (2075 m) in the lamina propria. Histology shows an infiltrate of the lamina propria in the antrum or body by plasma cells, lymphocytes and rare neutrophils, and a marked intraepithelial infiltrate with T lymphocytes. Eosinophilic gastritis is associated with peripheral eosinophilia and eosinophilic infiltration of the stomach, involving one or more layers of the gastrointestinal tract (mucosa, muscle or subserosa). Hypertrophic Gastropathies There are numerous causes of thickened gastric folds seen on endoscopy or diagnostic imaging (Table 2). Mntriers disease is associated with protein- losing gastropathy and hypochlorhydria whereas hyperplastic, hypersecretory gastropathy is associated with increased or normal acid secretion and hyper- plasia of the parietal and chief cells, with or without protein loss. Endoscopy, in both cases, typically shows irregular hypertrophic folds involving the body of the stomach, although there is a polypoid variant that resembles multiple hyperplastic gastric polyps. The characteristic histological features are foveolar hyperplasia with cystic dilation; inflammatory infiltrates may be present, as in hypertrophic lymphocytic gastritis, but this is variable. Gastric resection for refractory protein loss, hemorrhage or obstruction is a last resort. Miscellaneous Gastritides Gastritis cystica profunda is a rare sequela of partial gastrectomy with gastro- jejunostomy but it may also develop in the absence of prior gastric surgery. Endoscopy typically shows multiple exophytic gastric masses, which on sec- tion reveal multiple cysts. At histology, foveolar hyperplasia is accompanied by cystic glands that extend through the muscularis mucosae into the submucosa and muscularis propria. It may be associated with chronic atrophic gastritis, hyperplasia or primary gastric stump cancer after surgery. Gastric Polyps and Gastric Malignancy There are numerous types of gastric polyps (Table 4) which are usually incidental findings with little risk of developing into cancer. Gastric polyps are gastric epithelial or non- epithelial protrusions observed either endoscopically or radiologically. The non-epithelial polyps arise from the mesenchymal tissue of the submucosa (such as a leiomyoma). The epithelial polyps are most common, and are often multiple, hyperplastic polyps. Infre- quently, adenomatous or villoadenomatous polyps, which are often singular, occur. Individuals with a parent or sibling with gastric cancer are three times as likely to develop gastric cancer as the general population. Although regular screening is not warranted in either case, minor symptoms should be promptly and thoroughly investigated. In Canada there were 2,800 new gastric cancer cases in 2001 (8 per 100,000) and 1,950 deaths. There are numerous risk factors associated with the development of gastric adenocarcinoma (Table 5). The incidence of gastric adenocarcinoma has been falling dramatically in North America from ~ 30 per 100,000 in the 1930s to 68 per 100,000 at present. There is a disparity in adenocarcinoma incidence between first- and second-generation immigrants, suggesting both genetic and lifestyle or environmental factors together contribute to the risk for cancer. Genetic factors that increase the risk include low gastric acid secretory status and the presence of pro-inflammatory genes such as interleukin-1, which is associated with gastric acid hyposecretion. Several lifestyle factors including diet and smoking increase the risk of gastric cancer but these are potentially modifi- able.

Sleisenger & Fordtrans Gastrointestinal and Liver Disease: Pathophysiology/Diagnosis/Management 2006: pg 1149. Environmental Risk Factors Dietary factors that contribute to gastric cancer include a high dietary salt and nitrate/nitrite intake, low fruit and vegetable intake, and the use of tobacco. Persons with the highest intake of vegetables have a significantly reduced risk of gastric cancer compared to those who consume no vegetables. Similar but weaker protective effects have also been observed for consumption of green and cruciferous vegetables. Current smoking adversely influences the risk for gastric cancer, and this risk increases with the intensity and duration of cigarette smoking.

Shaffer 158 higher risk for gastric cancer than older patients, presumably because of their having a longer duration of exposure. In a proportion of patients with chronic atrophic gastritis, intestinal metaplasia develops and, in a much smaller proportion, dysplasia and subsequently cancer (Table 5). Recent studies have shown the importance of inflammation, arising from the initial H. Patients with the interleukin-1 gene cluster polymorphism, which may enhance production of the proinflammatory cytokine interleukin-13, are at increased risk of H. Thus, host genetic factors that affect interleukin- 1 production and hypochlorhydria may influence gastric cancer risk in those infected with H. Such exciting advances in the genetics of gastric cancer promise a means to identify early those who are at risk of this serious malignancy.

Confirmatory diagnosis is usually made at endoscopy when biopsies and the intraluminal extent can be determined.

Definition Digestive disorders and diseases significantly affect millions of persons worldwide inducing a highly significant economical impact comprising health care costs and work absenteeism, in addition to patients decreased quality of life. Organic diseases reviewed in this document include gastroesophageal reflux disease, Helicobacter pylori infection, and colorectal cancer. Objectives The aim of this document is to estimate the prevalence of digestive disorders and diseases on human health under a global worldwide perspective. The approach was not restricted to life-threatening diseases but also to functional disorders, those conditions with potential impact on well-being and quality of life. For this purpose, a group of experts proposed an initial list of gastroenterological disorders or diseases to be investigated. Criteria for the selection of appropriate conditions were: first, their prevalence should be admittedly high, i. Methodology The first step was to establish definition and diagnostic criteria for each condition. Thereafter, the study has been developed by reference searches in medical databases together with data compiled by a questionnaire-based survey with the collaboration of the National Societies of Gastroenterology that are members of the World Gastroenterology Organization. The final set of data was therefore composed by both statistical data published in scientific articles and information received directly from the National Societies. The main output consists in Tables of data as obtained from the above mentioned sources, showing national prevalence (incidence for colo-rectal cancer). Heartburn is defined as a burning sensation in the retrosternal area, and regurgitation as the perception of flow of acidic material into the mouth or hypo pharynx. Extra esophageal symptoms include sore throat, cough, dysphagia and sleep disturbance. Other processes denominated as atypical manifestations, or extra esophageal manifestations have been classified basically in three groups: breathing manifestations, thoracic atypical pain and manifestations of the oto- rhino-laryngea area and of the oral cavity. This is important considering that permanent acid reflux can induce esophageal complications such as esophagitis (i.

Psychophysiological Insomnia The essential features of this disorder are heightened arousal and learned sleep-preventing as- sociations. Individuals typically have increased concern about sleep diffculties and their consequences, leading to a vicious cycle of arousal, poor sleep, and frustration. Paradoxical Insomnia The essential feature of this disorder is a complaint of severe or nearly total insomnia that greatly exceeds objective evidence of sleep disturbance and is not commensurate with the re- ported degree of daytime defcit. To some extent, misperception of the severity of sleep disturbance may characterize all insomnia disorders. Idiopathic Insomnia The essential feature of this disorder is a persistent complaint of insomnia with insidious on- set during infancy or early childhood and no or few extended periods of sustained remission. Idiopathic insomnia is not associated with specifc precipitating or perpetuating factors. Insomnia Due to Mental Disorder The essential feature of this disorder is the occurrence of insomnia that occurs exclusively during the course of a mental disorder, and is judged to be caused by that disorder. The insom- nia is of suffcient severity to cause distress or to require separate treatment. This diagnosis is not used to explain insomnia that has a course independent of the associated mental disorder, as is not routinely made in individuals with the usual severity of sleep symptoms for an associated mental disorder. Inadequate Sleep Hygiene The essential feature of this disorder is insomnia associated with voluntary sleep practices or activities that are inconsistent with good sleep quality and daytime alertness. Some element of poor sleep hygiene may character- ize individuals with other insomnia disorders. When the identifed substance is stopped, and after discontinuation effects subside, the insomnia is expected to resolve or sub- stantially improve. Insomnia Due to Medical Condition The essential feature of this disorder is insomnia caused by a coexisting medical disorder or other physiological factor. Although insomnia is commonly associated with many medi- cal conditions, this diagnosis should be used when the insomnia causes marked distress or warrants separate clinical attention. This diagnosis is not used to explain insomnia that has a course independent of the associated medical disorder, and is not routinely made in individu- als with the usual severity of sleep symptoms for an associated medical disorder. These diagnoses are Unspecifed typically used when further evaluation is required to identify specifc associated conditions, or when the patient fails to meet criteria for a more specifc disorder. These objectives are accomplished by: insomnia, maladaptive efforts to accommodate to the condition I.

Triazolam has been associated with to treatment for this common and chronic disorder. These negative states are frequently conditioned in response to efforts to sleep as a result of prolonged periods of time in bed awake. The objectives of stimulus control therapy are for the patient to form a positive and clear association between the bed and sleep and to establish a stable sleep-wake schedule. Patients should be advised to leave the bed after they have perceived not to sleep within approximately 20 minutes, rather than actual clock- watching which should be avoided. Relaxation training (Standard) such as progressive muscle relaxation, guided imagery, or abdominal breathing, is designed to lower somatic and cognitive arousal states which interfere with sleep. Instructions: Progressive muscle relaxation training involves methodical tensing and relaxing different muscle groups throughout the body. Cognitive therapy seeks to change the patients overvalued beliefs and unrealistic expectations about sleep. Cognitive therapy uses a psychotherapeutic method to reconstruct cognitive pathways with positive and appropriate concepts about sleep and its effects. Common cognitive distortions that are identifed and addressed in the course of treatment include: I cant sleep without medication, I have a chemical imbalance, If I cant sleep I should stay in bed and rest, My life will be ruined if I cant sleep. Many therapists use some form of multimodal approach in treating chronic insomnia. Sleep restriction (Guideline) initially limits the time in bed to the total sleep time, as derived from baseline sleep logs. This approach is intended to improve sleep continuity by using sleep restriction to enhance sleep drive. As sleep drive increases and the window of oppor- tunity for sleep remains restricted with daytime napping prohibited, sleep becomes more consolidated. When sleep continuity substantially improves, time in bed is gradually increased, to provide suffcient sleep time for the patient to feel rested during the day, while preserving the newly acquired sleep consolidation. In addition, the approach is consistent with stimulus control goals in that it minimizes the amount of time spent in bed awake helping to restore the association between bed and sleeping. Paradoxical intention (Guideline) is a specifc cognitive therapy in which the patient is trained to confront the fear of staying awake and its potential effects. Biofeedback therapy (Guideline) trains the patient to control some physiologic variable through visual or auditory feedback. Sleep hygiene therapy (No recommendation) involves teaching patients about healthy lifestyle practices that improve sleep. It should be used in conjunction with stimulus control, relaxation training, sleep restriction or cognitive therapy.
