Esophageal achalasia associated with gastric carcinoma: lack of evidence for widespread plexus destruction.

Achalasia of the esophagus occurred in association with gastric carcinoma involving the cardia. Except in a limited area subjacent to the squamocolumnar junction, the pathologic findings were unusual in that the myenteric plexus of the body of the esophagus was intact and apparently uninvolved. The hypothesis is advanced that, in this instance, the achalasia could be classified as a tumour-associated funnctional disorder due to distant neural involvement rather than to local invasion with plexus destruction.

Comparison of Type A and nutrient standard menus for school lunch. III. Nutritive content of menus and acceptability.

The caclulated nutritional value of school lunches for fifth and tenth grade students planned according to the Type A pattern and a nutrient standard (NSM) WEre compared on the basis of meals as planned, served, and eaten. On an "as eaten" basis, menus planned by both methods were low in calories, iron, and thiamin. Although the differences were small, the NSM menus were consistently higher in nutrients, including calories, iron, and thiamin, and lower in percentage of calories coming from fat.

Comparison of Type A and nutrient standard menus for school lunch. II. Management aspects.

An extensive study compared school lunches planned to meet a specific nutrient standard (NSM) with those planned according to the Type A pattern. Average daily participation, food and labor costs, accuracy of the menus, and differences in the four-week menus between the two methods are reported. Twenty-nine menu planners representing a variety of living environments quickly learned the NSM method and enthusiastically planned and served the Type A and NSM test menus to fifth and tenth grade students.

Comparison of Type A and nutrient standard menus for school lunch. I. Development of the nutrient standard method (NSM).

Methodology was developed for planning school lunch menus which meet a specific nutrient standard. The method considered nine indicator nutrients plus calories and percentage of calories coming from fat. The nutrient composition of approximately 625 school lunch menu items were calculated using Agriculture Handbook No.

Constipated plasma cells associated with monomeric macroglobulinemia.

Low molecular weight macroglobulinemia was observed in a patient with chronic pulmonary infection. An enlarged cervical lymph node contained many abnormal plasma cells, which were distended with immunoglobulin; this material appeared to be released into lymph spaces when the cells burst. The macroglobulin production is considered to be a non-neoplastic reactive immune response to the pulmonary infection.

Mushroom poisoning in Canada: report of a fatal case.

At least 150 cases of mushroom poisoning occur in Canada each year, 75% in the Province of Ontario. Eighty per cent of the total are in children under the age of 9, and most do not require hospitalization. Amanita virosa poisoning is a potentially fatal medical emergency which presents as an acute gastroenteritis, progressing to hepatorenal failure.

Idiopathic neonatal hepatitis: discordance in monozygotic twins.

Idiopathic neonatal hepatitis is the uncommon syndrome of prolonged obstructive jaundice associated with giant cell transformation in the liver and patent bile ducts. Either hepatitis virus or an inherited abnormality has been suggested as a likely pathogenic agent for the syndrome.Recent observation of discordance for idiopathic neonatal hepatitis in monozygotic twins is felt to be inconsistent with either an infectious or a simple genetic etiology.
