This article uses social practice theory to examine the role of information-seeking in the maintenance of existing lifestyle and illness-related adjustments in the context of chronic illnesses. The research findings are derived from a thematic analysis of 16 semi-structured in-depth interviews with Estonian Parkinson's disease patients. The coding scheme bases on the four practice elements outlined by Schatzki (practical understandings, rules, teleological structures and general understandings) and other categories related to chronic illness self-management skills, bodily movements, daily routines and information-seeking practices.

Aim: To determine if patients can localise dysphagia level determined endoscopically or radiologically and association of gender, age, level and pathology.

Methods: Retrospective review of consecutive patients presenting to dysphagia hotline between March 2004 and March 2015 was carried out. Demographics, clinical history and investigation findings were recorded including patient perception of obstruction level (pharyngeal, mid sternal or low sternal) was documented and the actual level of obstruction found on endoscopic or radiological examination (if any) was noted.

Introduction: Benign esophageal strictures arise from various etiologies and are frequently encountered. Although endoscopic dilation is still the first-line therapy, recurrent strictures do occur in approximately 10% of the cases and remains a challenge to gastroenterologists. Areas covered: A literature search was performed using PubMed and Google Scholar databases for original and review articles on endoscopic treatment of benign esophageal strictures. Read More

Objective: Symptomatic lower esophageal (Schatzki) rings are one of the most common causes of dysphagia and esophageal food impaction. Although these rings are often diagnosed fluoroscopically, patients are typically referred for dilation procedures performed by a gastroenterologist. Because these procedures are invasive and carry risks, including esophageal perforation, an alternative treatment option is needed. Read More

Background And Aims: Schatzki rings are found in the distal esophagus, are associated with hiatal hernias, and present with intermittent dysphagia to solid foods. They can be identified by radiology (GI series or barium swallow studies) or endoscopy. Rings are not always visualized during endoscopy in patients in whom they are suspected clinically. Read More

Acute oesophageal symptoms include acute dysphagia or food bolus impaction (most commonly due to strictures, Schatzki ring and eosinophilic oesophagitis), acute chest pain with odynophagia due to oesophageal infections, motility disorders and acute oesophageal rupture (of which oesophageal intramural haematoma is a subtype). Acute full thickness oesophageal rupture carries a high mortality if not recognised early; the clinical features and conditions with which this may be confused are presented and discussed. Read More

Opinion Statement: Benign esophageal strictures arise from a diversity of causes, for example esophagogastric reflux, esophageal resection, radiation therapy, ablative therapy, or the ingestion of a corrosive substance. Most strictures can be treated successfully with endoscopic dilation using bougies or balloons, with only a few complications. Nonetheless, approximately one third of patients develop recurrent symptoms after dilation within the first year. Read More

Following winter oilseed rape cultivation, considerable numbers of volunteer oilseed rape plants may occur in subsequent years in following crops. The appearance of volunteer oilseed rape plants is based on the capability of the seeds to become secondary dormant and to survive in this stage for many years in the soil. Genetic reduction of secondary seed dormancy in oilseed rape could provide a means to reduce the frequency of volunteer plants and especially the dispersal of transgenic oilseed rape. Read More

Esophageal strictures are a common problem in gastroenterological practice. In general, the management of malignant or benign esophageal strictures is different and requires a different treatment approach. In daily clinical practice, stent placement is a commonly used modality for the palliation of incurable malignant strictures causing dysphagia, whereas, if available, intraluminal brachytherapy can be considered in patients with a good performance status.

Esophageal strictures are a problem frequently encountered by gastroenterologists. Dilation has been the customary treatment for benign esophageal strictures, and dilation techniques have advanced over the years. Depending on their characteristics and the response to treatment, esophageal strictures can be classified into two types: 1, simple (Schatzki rings, webs, peptic injury, and following sclerotherapy) - these are easily amenable to dilation, with a low recurrence rate after initial treatment; and 2, complex (caused by caustic ingestion, radiation injury, anastomotic strictures, and photodynamic therapy) - these are difficult to dilate and are associated with higher recurrence rates.

Eponyms in medicine are frequently criticized because they may not represent the person who first described a syndrome or disease. Although eponyms are very commonly used, most readers are probably unaware of who it was that named the diseases and whether the original description of the disease still corresponds to the modern definition. The 10 most common eponyms in esophageal diseases were revisited. Read More
