1/17. Foreign body ingestion in children with severe developmental disabilities: a case study.Dysphagia is common in children with severe developmental disabilities. The nature of these difficulties can predispose them to foreign body ingestion. This article presents a case that highlights the need for vigilance in diagnosing dysphagia in children with multiple and complex developmental disabilities where severe cognitive impairment and an inability to communicate may mask the presence of underlying problems.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
2/17. Approach to the patient with unexplained chest pain.patients with unexplained or noncardiac chest pain continue to present a difficult challenge to the gastroenterologist. Cardiac disease must be ruled out first as the history will not distinguish between coronary artery disease and other causes of substernal chest pain. A systematic approach to evaluation should include reassurance that the heart is normal and attempts to confirm an esophageal etiology. gastroesophageal reflux disease is the most common esophageal abnormality associated with unexplained chest pain and may be identified by an aggressive trial of anti-reflux therapy or an abnormal prolonged ambulatory pH monitoring study. endoscopy is almost always normal and of less use in this population than in those with heartburn as the presenting symptom. Judicious use of manometry with provocative testing to evaluate for esophageal motility abnormalities or esophageal sensitivity allows for optimal evaluation of those who do not have gastroesophageal reflux disease. This article reviews the clinical presentation, differential diagnosis, and approach to evaluation and therapy of this complex group of patients.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
3/17. The possible role of helicobacter pylori in GERD.A variety of abnormalities contribute to the development of gastroesophageal reflux disease (GERD) including transient lower esophageal sphincter relaxation, low esophageal sphincter pressure, presence of a hiatal hernia, diminished esophageal clearance of refluxed gastric contents, and alterations in esophageal mucosal resistance. helicobacter pylori infection clearly plays a role in the pathogenesis of peptic ulcer disease and mucosa associated lymphoma of the stomach and is a definite risk factor for distal gastric cancer. The role of H. pylori infection in GERD remains controversial and incompletely understood. Although H. pylori infection does not cause reflux disease, circumstantial evidence suggests that it may protect against the development of GERD and its complications in some patients. The most likely mechanism whereby H. pylori infection protects against GERD is by decreasing the potency of the gastric refluxate in patients with corpus predominant gastritis. A variety of implications of H. pylori infection on GERD treatment have also arisen in recent years. These focus on the risk of gastric atrophy while on proton pump inhibitor therapy and the efficacy of proton pump inhibitors before and after eradication of H. pylori. This article puts into perspective our current understanding of the complex, incompletely understood relationship between H. pylori infection and GERD.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
4/17. An evaluation of the Nissen fundoplication.The characteristic radiological findings which follow a Nissen fundoplication are reviewed. The esophagus may be narrowed but is intrinsically normal. A pseudotumor at the medial aspect of the fundus is generally present. The history and radiographic findings can normally differentiate this defect from neoplasm or a nonoperated hiatal hernia. Postoperative clinical evaluation has shown this procedure to be very valuable in the amelioration of symptoms.- - - - - - - - - - ranking = 1.1391968955417keywords = neoplasm (Clic here for more details about this article) |
5/17. The value of reoperative procedures after unusual reconstructions in the gastrointestinal tract associated with substantial morbidity.Reconstructive procedures of the gastrointestinal tract after resection or for bypass surgery are well established and almost completely standardized but still may cause significant morbidity. Deviations from standard reconstructive procedures have pitfalls, especially when complex reconstructions are required, and may lead to substantial morbidity. Scientific evidence for the indication to reoperate as well as the best methods to be applied is lacking and surgical experience indispensable. We report on 10 reoperative cases between 1999 and 2003 after uncommon reconstructive procedures in the gastrointestinal tract associated with substantial morbidity. In five cases (five of seven), operative correction of uncommon reconstructions in the upper gastrointestinal tract after gastrectomy, completion gastrectomy, or distal gastric resection could completely alleviate the complaints including reflux esophagitis, whereas incomplete relief of symptoms was achieved in the remaining two cases (two of seven). Corrective procedures used end-to-side esophagojejunostomy or end-to-side gastrojejunostomy with a retrocolic isoperistaltic jejunal Roux-en-Y loop and end-to-side jejunojejunostomy approximately 40 cm distal to the proximal anastomosis for biliary and exocrine pancreatic drainage. After biliodigestive anastomosis, problematic cholangitis could be completely alleviated in three cases (three of three) using end-to-side hepaticojejunostomy with a retrocolic isoperistaltic jejunal Roux-en-Y loop and end-to-side jejunojejunostomy 40 cm distal to the hepaticojejunostomy for reconstruction of the continuity of the gastrointestinal tract. compliance with well-established standard reconstructive procedures is of elementary importance in the gastrointestinal tract. Operative correction of uncommon reconstructions associated with morbidity is usually indicated.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
6/17. The redefinition of failure to thrive from a case study perspective.Explaining failure to thrive (FTT) in dichotomous terms--organic versus non-organic --no longer applies in the context of modern pediatric nursing. FTT has turned out to be much more multifaceted. One infant's story illustrates the complexities and long-term ramifications of a pediatric feeding disorder and the challenges faced by health care professionals and families in their care. The story illustrates how physiologic, sensorimotor, and behavioral issues can all impact a child's inability to gain weight as expected. With greater understanding, pediatric nurses can appreciate their role as members of a multidisciplinary pediatric feeding disorder team.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
7/17. Bilateral communicating bronchopulmonary foregut malformations in a child.Communicating bronchopulmonary foregut malformations are rare anomalies. The complex anatomy requires innovative surgical techniques. We report a child with bilateral sequestrations communicating with the lower esophagus. The sequestrations were excised through a single thoracotomy incision and the esophagus was repaired. Postoperatively the child has remained asymptomatic.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
8/17. Abrikosoff's tumor of the esophagus: case report and review of literature.Abrikosoff's tumor or granular cell tumor is a neoplasm of neural origin, usually located in the head and neck region. A majority of these neoplasms are benign. Only 4-6% of granular cell tumors are located in the gastrointestinal tract. It is extremely unusual for these tumors to be located in the esophagus. This case is being reported in view of the rarity of this lesion. A brief review of literature with stress on diagnostic evaluation and management issues is also included.- - - - - - - - - - ranking = 2.2783937910834keywords = neoplasm (Clic here for more details about this article) |
9/17. Dysphagia-gastroesophageal reflux complex: complications due to dysfunction of solitary tract nucleus-mediated vago-vagal reflex.We report on the complication of gastroesophageal reflux (GER) in four patients with lower brainstem dysfunction. These patients suffered from perinatal asphyxia, cerebellar hemorrhage, or congenital dysphagia of unknown origin and showed facial nerve palsy, inspiratory stridor due to vocal cord paralysis, central sleep apnea, and dysphagia, in various combinations. Naso-intestinal tube feeding was introduced in all of the patients due to recurrent vomiting and aspiration pneumonia resulting from GER. T2-weighted magnetic resonance (MR) imaging revealed symmetrical high intensity lesions in the tegmentum of the lower pons and the medulla oblongata in two of the patients, and pontomedullary atrophy in another patient. In normal subjects, lower esophageal sphincter contraction is provoked by distension of the gastric wall, through a vago-vagal reflex. Since this reflex arc involves the solitary tract nucleus, where the swallowing center is located, the association of dysphagia and GER in the present patients is thought to result from the lesions in the tegmentum of medulla oblongata. We propose the term "dysphagia-GER complex" to describe the disturbed motility of the upper digestive tract due to lower brainstem involvement. In children with brainstem lesions, neurological assessment of GER is warranted, in addition to the examination of other signs of brainstem dysfunction, including dysphagia and respiratory disturbance.- - - - - - - - - - ranking = 5keywords = complex (Clic here for more details about this article) |
10/17. Chronic dysphagia, vomiting and gastroesophageal reflux as manifestations of a brain stem glioma: a case report.brain stem glioma is the third most common childhood brain tumor, comprising 10-15% of this group of neoplasms. Typical presenting symptoms include ataxia, diplopia and headache, while signs of increased intracranial pressure occur later in the clinical course. Although prolonged failure to thrive, characterized by cachexia and vomiting are rare manifestations of brain stem lesions, in this study we report a 9.5-year-old boy with failure to thrive since infancy which remitted after excision of a brain stem astrocytoma.- - - - - - - - - - ranking = 1.1391968955417keywords = neoplasm (Clic here for more details about this article) |
