OBJECTIVE To examine the prevalence and risk factors of vitamin deficiencies among older Thai adults. METHODS The cross-sectional study was conducted in four rural communities, one from each of the four main regions of Thailand. In total, 2336 subjects aged 60 years and over were recruited. Anthropometric variables, demographic data, blood glucose and lipid profile, albumin, globulin and bloo...

multiple risk factors are introduced for multiple sclerosis (ms). recent studies have suggested a possible correlation between vitamin d deficiency and an increase risk of ms. this study was therefore undertaken to compare vitamin d levels in new cases of ms and their relatives as healthy controls. seventy five new diagnosed ms patients and 100 matched healthy controls among their relatives wer...

Patients with coumarin induced skin necrosis presents with painful purpura and erythematous bluish swelling of the skin complicated by blister formation, hemorrhage and immanent gangrene. Coumarin induced hemorrhagic skin necrosis occurs within one week after initiation of coumarin treatment at time of prolonged INR caused by an imbalance within the vitamin K dependent anticoagulant and procoag...

UNLABELLED Chronic liver disease (CLD) and several related extrahepatic manifestations such as hepatic osteodystrophy are associated with deficiency of vitamin D, which has therefore been suggested as therapeutic target. Vitamin D undergoes hepatic 25-hydroxylation, rendering the liver critical to the metabolic activation of this vitamin. Vitamin D deficiency is highly prevalent in CLD patients...

introduction: vitamin d has an important role in maintaining human health. the main source of vitamin d production is skin exposure to sunlight. accordingly with the spread of apartment life culture, growth of industrial cities and the increase of air pollution; vitamin d deficiency and its implications is an important factor in the appearance of debilitating diseases in different age categorie...

Vitamin C deficiency generally results from little to no intake of ascorbic acid, and it often presents with small-volume bleeding. Rarely vitamin C deficiency causes hemodynamically significant bleeding. Here we present a middle-aged man who was admitted to the hospital several times for hypotension, recurring lower extremity ecchymoses, and persistent anemia. Extensive workup from previous ho...

Vitamin D deficiency is one of the major health problems that is unexpectedly prevalent in Iran. The ultraviolet (UV) rays of the sunlight are the most important source of vitamin D in humans. In contrast, environmental factors are one of the reasons for decrease in UV transmission to the earth which results in the reduction of vitamin D absorption. Since the role of environmental factors has b...

BACKGROUND The neonatal brain is particularly vulnerable to imbalances in redox homeostasis because of rapid growth and immature antioxidant systems. Vitamin C has been shown to have a key function in the brain, and during states of deficiency it is able to retain higher concentrations of vitamin C than other organs. However, because neurons maintain one of the highest intracellular concentrati...

OBJECTIVE To describe the epidemiology of Vitamin A and C and folic acid deficiencies and their association with sociodemographic and dietary factors in a national probabilistic sample of Mexican women and children. MATERIAL AND METHODS This is a probabilistic sample from the National Nutrition Survey 1999 (ENN-99) including 1,966 children and 920 women. Vitamins A and C were measured in seru...
