The usual dietary sources of Vitamin B12 are animal-derived foods, although a few plant-based foods contain substantial amounts of Vitamin B12. To prevent Vitamin B12 deficiency in high-risk populations such as vegetarians, it is necessary to identify plant-derived foods that contain high levels of Vitamin B12. A survey of naturally occurring plant-derived food sources with high Vitamin B12 con...

OBJECTIVE To study unusual psychiatric manifestation of vitamin B12 deficiency and related issues. METHOD A case study of 52-year-old female and review of relevant literature. RESULTS Complete remission of psychiatric symptoms without recurrence for the next 4 years with vitamin B12 as the only specific therapy instituted. CONCLUSION Importance of B12 estimation and replacement in patient...

BACKGROUND & OBJECTIVES The prevalence of anaemia has been well studied particularly on etiology of nutritional anaemia in children of age group 5-10.9 yr in India. The present study was carried out to find out the prevalence and etiology of nutritional anaemia among 5 to 10.9 yr old corporation school children from urban slums. METHODS Urban Delhi slums were divided into four areas and one c...

our findings is that the concentration of HC is influenced by the vitamin B12 status of the patient. The issue has important implications for the interpretation of low cobalamin in relation to low HC concentrations in patients undergoing examination for vitamin B12 deficiency. If genetic factors were the only regulators of the HC concentration, the physician could decide that the low concentrat...

Subnormal red-cell folate values were encountered in 20 of 63 thalassaemic subjects in a population with a low incidence of megaloblastosis. The abnormality was not associated with haematological changes of megaloblastosis and could not be explained on the basis of incomplete liberation of intra-erythrocytic folates, serum conjugase deficiency of vitamin B12 deficiency. Evidence is presented to...

Vitamin B12 deficiency is uncommon in pregnancy, it occurs in 10-28% of uncomplicated pregnancies, and is associated with a few complications. We present a case report of a 21-year-old patient with severe anaemia during late pregnancy caused by vitamin B12 deficiency. At 38 weeks gestation and with a BMI of 48.9, a history of rupture of membranes was given but not confirmed. On examination, she...

BACKGROUND Vitamin B12 deficiency is associated with a wide spectrum of neuro-psychiatric manifestations. RESULTS We report a case of a 44 year old female patient referred to the haematology unit with vitamin B12 deficiency presenting as an acute confusional state or delirium. Total resolution of the psychiatric symptoms occurred following parenteral vitamin B12 replacement therapy. CONCLUS...

BACKGROUND Elevated concentration of serum total homocysteine usually occurs in vitamin B-12 deficiency. This metabolite can be measured and used for screening functional vitamin B-12 deficiency. OBJECTIVES We assessed functional vitamin B12 deficiency in Tehranian elderly admitted to elderly research center, University of Social Welfare and Rehabilitation Sciences. PATIENTS AND MATERIALS A...

Hypercobalaminemia (high serum vitamin B12 levels) is a frequent and underestimated anomaly. Clinically, it can be paradoxically accompanied by signs of deficiency, reflecting a functional deficiency linked to qualitative abnormalities, which are related to defects in tissue uptake and action of vitamin B12. The aetiological profile of high serum cobalamin predominantly encompasses severe disea...
