Hour-glass stricture of the stomach and iron deficiency.
THE object of this note is to put forward the hypothesis that hour-glass stricture of the stomach occurs in persons with a chronic simple gastric ulcer of the lesser curvature, because these persons also have chronic iron deficiency, and that the stricture would not occur without the co-existence of the iron deficiency. Seven cases are described. An association with Plummer-Vinson stricture of ...
متن کاملOn hour-glass sector zoning in clinopyroxene
The observations of hour-glass sector zoning from four selected clinopyroxenes in undersaturated lavas best fit a model in which the sector zoning is formed due to a structural requirement in a growth direction normal to {IOO} where a high concentration of silicate units, required to build the silicate chains, is unsatisfied. In these sectors AI substitutes for Si, the charge balance being main...

متن کاملVertebral artery occlusion by a cervical 'hour-glass' neurofibroma.
A case of total vertebral artery occlusion by a cervical `hour-glass' or `dumb-bell' neurofibroma is reported. To the author's knowledge this is the first reported case in the English literature. A causal relationship between the arterial occlusion and the patient's symptoms has been postulated. The angiographic study of these patients is further emphasized to enhance safer and more effectual r...
