Although uncommon in clinical practice, this syndrome represents one of the main causes of intestinal failure and is characterized by high morbidity and mortality. It may be idiopathic or secondary to a variety of diseases. Most cases are sporadic, even though familial forms with either dominant or recessive autosomal inheritance have been described. Based on histological features in- testinal pseudo-obstruction can be classified into three main categories:neuropathies, mesenchymopathies, and myopathies, according on the predominant involvement of enteric neurones, interstitial cells of Cajal or smooth muscle cells, respectively. Treatment of intestinal pseu- do-obstruction involves nutritional, pharmacological and surgical therapies, but it is often unsatisfactory and the long-term outcome is generally poor in the majority of cases.展开更多

These voids are not lined with epithelia. There are few reported cases about colon, duodenum and skin. Because there is only one case report about pseudolipomatosis in the stomach, we reevaluated 909 endoscopic biopsies taken from gastric corpus to check the presence of pseudolipomatosis. We determined pseudolipomatosis foci in 3 percent (n=27) of biopsies. In two cases there were pseudolipomatosis foci in endoscopic biopsies having otherwise normal histologic findings, while there were pseudolipomatosis foci in endoscopic biopsies of 25 patients with gastritis. H pylori was found in 85 % of biopsies having pseudolipomatosis foci. In this study, we presented some histopathologic characteristics of pseudolipomatosis seen in gastric mucosa.展开更多

A questionnaire was distributed to 372 practitioners in various private and government organizations. Practitioners were asked how influential and relevant public relations ethical factors were on the practitioner＇s perception of ethics. Findings suggest that the daily practice of public relations day-by-day professionally practice learning, senior practitioners, senior executives, and managers along with religion play a major role in shaping the meaning, philosophy, and conception of the practitioner＇s ethics. Respondents were asked to describe the level of support they would give to the controversial public relations practices that may generate some ethical problems. The majority of the respondents did not agree on the use of ＂spreading rumors＂, ＂providing false information to satisfy the public＂, ＂misinformation and manipulation＂, ＂giving false promises＂, and ＂would not approve favoring personal interest over public interest＂.展开更多
