Anemia is a common complication of human malaria. Since micronutrient deficiencies are highly prevalent in malaria-endemic areas and appear to contribute to anemia etiology, we conducted a cross-sectional study in Tumaco, Colombia, to examine the associations between plasma vitamin B12 or erythrocyte folate concentrations and hemoglobin (Hb) among 96 adults with predominantly Plasmodium falcipa...

We report a case of anaphylactic reaction to intramuscular injection of cyanocobalamin. This 52-year-old lady was diagnosed as a case of megaloblastic anemia secondary to dietary vitamin B12 deficiency. She had severe anaphylactic reaction after the parenteral administration of cyanocobalamine. Later she received oral vitamin B12 with no adverse effects. The purpose of this case report is to dr...

Vitamin B12 deficiency is an uncommon cause of pyrexia. We report the case of a patient who presented with pyrexia and anaemia, which after exclusion of infective, inflammatory or endocrine causes was attributed to megaloblastic anaemia secondary to vitamin B12 deficiency. The patient's fever responded to treatment of vitamin B12 deficiency.

Pancytopenia can rarely complicate Grave's disease. It can be due to uncontrolled thyrotoxicosis or as a result of rare side effect of antithyroid medication. Pernicious anemia leading to Vitamin B12 deficiency is another rare associated cause. We report a case of a patient with Grave's disease and undiagnosed pernicious anemia whom was assumed to have antithyroid drug induced pancytopenia. Fai...

• All adult kidney transplant recipients should be monitored for anaemia. • Possible dietary causes of anaemia, including iron, folate and vitamin B12 deficiencies, should be investigated. • A dietitian should be consulted if dietary deficiencies are shown to be contributing to anaemia. • It is appropriate to use pharmacological doses of nutrients in conjunction with dietary interventions to co...

To determine whether the high incidence of tuberculosis among Asiatic Indians in the United Kingdom was due to impaired killing of Mycobacterium tuberculosis by macrophages from patients deficient in cobalamin, a nutritional survey was carried out among 1187 Indians and the incidence of tuberculosis determined from medical records. The question asked was whether tuberculosis was significantly m...

as we know, no attempts to compare quantitatively the expected amount prescribed, on the basis of good clinical practice, with that actually prescribed. There are in general three reasons for this-ignorance of the prevalence of common diseases, the lack of specificity of particular drugs for particular diseases, and the lack of standardization of therapy. Such a study requires a drug which is p...

قدرت تفکیک دستگاه طیف‌نگار جرمی به صورت مستقیم شدت یون خروجی و انرژی آن بستگی دارد. مقدار تولید شده جریان باریکه الکترونی وابسته است. از جمله وظایف مدار کنترل چشمه برخورد تنظیم برای رسیدن بهینه می‌باشد. در ساخت پارامترهایی نظیر تثبیت آن، دقیق پتانسل الکتریکی لنز الکترودهای یونی بسیار حایز اهمیت این مقاله با قابلیت انتشار الکترون، پتانسیل نقاط طراحی ساخته شد. کنترلر بر روی طیف نگار 44Varian MAT ...
