Transient lower esophageal sphincter relaxations (TLESRs) are neurally mediated abrupt reductions in lower esophageal sphincter (LES) pressure. TLESRs are not usually associated with deglutition or secondary peristalsis but are thought to be necessary for venting swallowed air from the stomach. Their central role in acid reflux, however, makes them a ...

Allergic disorders of the gastrointestinal tract were once thought of as primarily dermatological manifestations of common food allergens such as peanuts. Recently, greater attention to these products has arisen as complex mechanisms of action have been more clearly delineated. Specific disease states have recently been recognized associated with gastrointestinal reactions ...

We have reported tablet-induced focal esophagitis and esophageal stricture formation in cats. The proposed mechanism is thought to be abnormal esophageal tablet retention resulting in focal esophagitis with subsequent stricture formation. The objective of this study was to evaluate the passage of tablets and capsules when given alone (dry swallow) ...

BACKGROUND: Acute esophageal food impaction (AEFI) is the most common form of esophageal impaction in adults. The current recommendation for management is extraction by using an overtube to protect the airway, which facilitates multiple passages of the endoscope and protects the esophageal mucosa. Typically, AEFI in our patients is treated ...

Experts in the young field of violence epidemiology blame guns and crack cocaine for America's deadly crime surge in the early 1990s. Explaining the subsequent decline in violent crime rates has been more difficult, however. Some of the factors that seem to have helped squelch crime could be temporary, such ...

Megaoesophagus resulting from achalasia is a rare but serious cause of airway obstruction. The exact aetiology remains unclear. Although 29 cases have previously been reported, the potential need for urgent treatment has not been sufficiently emphasized. Some forms of treatment with drugs or decompression with a fine tube have been ...

Diffuse idiopathic skeletal hyperostosis (DISH), or Forestier's disease, is an ossifying condition frequently encountered in otolaryngology as it affects 12-28 per cent of the adult population. This form of hyperostosis can manifest clinically with dysphagia, food impaction, hoarseness, stridor, myelopathies and other neurological problems. Judicious management of severe dysphagia proves ...

BACKGROUND AND STUDY AIMS: Endoscopic extraction is the standard method of treating esophageal food bolus obstructions. The efficacy, efficiency, and safety of various techniques used over a 12-year period were evaluated. PATIENTS AND METHODS: Seventy-five procedures with soft food bolus obstruction were analyzed. If endoscopic extraction failed, or it was ...

Radiographic pelvimetry was used to assess the role of pelvic anatomy in obstructive dystocia in bitches. Based on the history of previous whelpings, 20 Boston terrier and 14 Scottish terrier bitches were divided into two equal groups: normally whelping bitches and bitches with obstructive dystocia. Additional whelpings during the period ...

We report two patients with lingual dyskinesia and complaints of food regurgitation following long-term antipsychotic therapy. Esophageal contrast radiography revealed dyskinetic movements extending from the pharynx to the upper portion of the esophagus. The elevation of intraesophageal pressure was confirmed by esophageal manometry. The dyskinetic movements almost disappeared along with ...

After a usual meal, a 57-year-old woman with normal hemostasis experienced a hematoemesis. She was then diagnosed endoscopically as having an intramural hematoma of the esophagus, which ranged from 18 cm to 24 cm from the incisors. The hematoma is considered to have developed not "spontaneously" but as a result ...

Partial splenectomy for Gaucher disease is often followed by reenlargement of the splenic remnant. It remains unclear if this process is due to tissue regeneration or to continued deposition of glucocerebroside in the reticuloendothelial system or both. We compared the splenic architecture before and after reenlargement in three cases of ...

Food borne diseases are an important public health problem. Over the past two decades, the epidemiology of food borne diseases has changed rapidly as a consequence of changes in the social environment and the ability of pathogens to adapt to new niches. Several newly recognized pathogens have emerged and well-recognized ...

Acoustic rhinometry and rhinomanometry have been used to assess nasal airway patency objectively. We compared nasal obstruction symptoms before and after decongestion with several parameters of these objective tests. The patients assessed their nasal obstruction using a visual analogue scale (VAS). Cross-sectional areas and nasal resistance were measured by acoustic ...

BACKGROUND: Food and acid have been shown to be refluxed independently of each other in healthy volunteers, and anti-reflux agents decrease the reflux of both parameters. Until now this phenomenon had not been studied in patients with low-grade oesophagitis, who are the group most likely to use anti-reflux medication. AIM: ...

Modern analytical techniques have to provide accurate results in time to permit forward approaches for controlling the microbiological quality of foods. Although the classical microbiological procedures of counting and identification of micro-organisms have been automated, several techniques with quite different principles are now used. The quantification of the microbial load ...

The consumer demands for less preserved foods and the development of new food systems to fulfil these demands, urges new hurdles for pathogen growth. The strategies for pathogen reduction are not selective for pathogenic microorganism and therefore the non-spoilage microorganisms may become also inactivated, from this situation a question of ...

A case with esophageal anisakiasis accompanied by reflux esophagitis is described. A 38-year-old man visited our hospital with complaints of heartburn and disturbance of food passage about seven hours after eating raw cuttlefish. The first esophagogastroscopy revealed an anisakis larva invading the squamocolumnar junction. Near the anisakis larva, a whitish ...

BACKGROUND: Although suggested, it has never been convincingly documented that food sensitivity is of pathogenetic importance in chronic inflammatory bowel disease. However, many patients may relate their gastrointestinal symptoms to specific food items ingested and may restrict their diet accordingly. METHODS: A questionnaire was sent to all patients with chronic ...

Different vehicles of transmission of the same pathogen may induce different clinical manifestations of the disease. The hypothesis was tested that the clinical manifestation of food-borne streptococcal pharyngitis is different from air-borne streptococcal pharyngitis. The symptoms and signs of 77 patients with endemic air-borne streptococcal pharyngitis compared to 103 patients ...

Trace element status in humans is often poorly established in developed, let alone developing, countries. There have been assumptions about inevitable adequacy, especially for ultra-trace elements, like chromium, with varied diets. However, new pressures on trace element adequacy are emerging, like developments in food technology with the new formulated foods ...

We investigated the relationship between airway inflammation and airway responsiveness, as assessed by PD15, to methacholine and to bradykinin in asthmatic patients. Bronchoalveolar lavage (BAL), bronchial biopsies, and methacholine and bradykinin challenges were performed in 18 nonsmoking subjects with mild or moderate perennial asthma. Bradykinin PD15 correlated negatively with eosinophil ...
