Gastric lupinoma: a new variety of phytobezoar.

A white 65-yr-old male who presented with epigastric pain and early satiety had a gastric bezoar composed of multiple lupini beans. Surgical removal was required due to the hard consistency of the mass. Gastric lupinomas has become a serious clinical problem, since lupini beans are currently used by unorthodox healers as an alleged treatment for arthritic pain.

Ulcer disease etiopathogenesis: an eclectic theory.

An eclectic theory of ulcer etiopathogenesis is presented. Its objective is to give a rational explanation to most of the disturbances and changes occurring in ulcer patients. The theory highlights the intricate cellular mechanisms which keep the balance between acid aggression and mucosal defense. The new theory presented here will serve as the skeletal framework upon which new biomedical and biopsychosocial development can be added to improve and expand the scientific explanation of why and how ulcers are formed.
