BACKGROUND A significant proportion of hemodialysis patients have functional, but modifiable, vitamin K deficiency. OBJECTIVE To determine the correlates of poor vitamin K status in hemodialysis patients. DESIGN Cross-sectional study. SETTING Hemodialysis units at Kingston General Hospital and its satellite centres, Ontario, Canada. PATIENTS Patients undergoing outpatient hemodialysis f...

Complex regional pain syndrome (CRPS) is the complication of some injuries, such as a fracture, which affects the distal end of the injured extremity characterized by pain, allodynia, hyperalgesia, edema, abnormal vasomotor and sudomotor activity, movement disorders, joint stiffness, regional osteoporosis, and dystrophic changes in soft tissue. Exact pathogenic mechanism of CRPS is still unclea...

We report a case of fat-soluble vitamin deficiency in a 14-year old boy who had chronic duodenal obstruction. He presented with periodic unexplained bleeding tendency. The laboratory results showed positive fat globules in stool and prolonged prothrombin time. His further investigation revealed low plasma vitamin A and undetectable plasma vitamin E. After parenteral vitamin K and oral vitamin A...

There have been methodological problems for studying hypovitaminosis D and K in the elderly. First, studies were done either by evaluating food intake or measuring their circulating levels, but rarely by both in Japan. In this paper, vitamin D and K intakes and their circulating levels were simultaneously determined. Second issue is whether hypovitaminosis D and K are independent of general mal...

Originally, vitamin K was defined as a factor concerned with haemostasis, deficiency resulting in a haemorrhagic disease. After the initial discovery of phylloquinone in 1929, various compounds were described which all had “vitamin K activity,” that is, the ability to restore normal haemostasis in vitamin K deficient animals. It turned out that “vitamin K” is a group name for several related co...

vitamin b12 (cobalamin) is an essential coenzyme for nucleic acid synthesis. animal protein is the major dietary source of vitamin b12. deficiency of vitamin b12 leads to megaloblastic anemia, degeneration of the brain, spinal cord, peripheral nerves, and abnormalities of epithelial tissues. two factors are necessary for the cure of megaloblastic anemia: one in food (extrinsic factor) and one i...

background: vitamin d deficiency during pregnancy is associated with some adverse pregnancy outcomes but its relationship with fetal growth is unknown. objective: we compared the 25-hydroxy vitamin d levels between mothers and their small for gestational age (sga) newborns with mothers and their appropriate for gestational age (aga) newborns. materials and methods: the study population included...
