Primary hyperparathyroidism in the primary care setting.
A series of 36 patients with surgically proved primary hyperparathyroidism is reported. From this group a clinical profile consisting of obesity, anxiety, and/or depression in a mildly hypertensive, middleaged female was derived. Women constituted 92 percent of the patients. The serum calcium was confirmed again as the single most valuable test in the evaluation of this disorder.

Trace elements in western Canadian hard red spring wheat (Triticum aestivum L.): levels and quality assurance.
A monitoring program was conducted for trace elements in Western Canadian Hard Red Spring wheat (Triticum aestivum L.). Samples were selected from harvest survey samples submitted by producers from crop districts in Manitoba, Saskatchewan, and Alberta for 1996, 1997, and 1998 crops. The analytical quality control measures used in these surveys are described along with the results for Cd, Cu, Fe, Mn, Se, and Zn. Accuracy and precision for the analyses fell within the acceptable control limits. Year-to-year variations in grain chemistry were small for Cd, Mn, Se, and Zn, but Cu and Fe contents showed 12 and 9% decreases, respectively, over the 3 years. The overall variability for the plant-essential trace elements-Cu, Fe, Mn, and Zn-was low compared with that for Cd and Se. The spatial variation in crop chemistry across the Canadian Prairie wheat-producing region was greater than the year-to-year variations. Soil properties were major factors in controlling Cd and Se levels in grain.
