Current recommendations for tuberculosis control are to screen high risk populations and provide chemoprophylaxis for those infected. In Edmonton, Alberta, one strategy has been to identify and provide TB skin tests to newly arrived immigrant school age children from TB endemic areas. The difficulty has been in identifying these children in the school population. This article describes a proces...

The aphid genus Aspidophorodon Verma, 1967 is reviewed, with descriptions of three new species from China, namely Aspidophorodon (Aspidophorodon) cornuatus Qiao sp. nov., Aspidophorodon (Aspidophorodon) musaicus Qiao sp. nov., and Aspidophorodon (Aspidophorodon) obtusus Qiao sp. nov.. Aspidophorodon sinisalicis Zhang, 1980 and Trichosiphonaphis lijiangensis Zhang, Zhong & Zhang, 1992 are consid...

BACKGROUND An increased prevalence of epilepsy has been reported in many onchocerciasis endemic areas. The objective of this study was to determine the prevalence of epilepsy in onchocerciasis endemic areas in the Democratic Republic of the Congo (DRC) and investigate whether a higher annual intake of Ivermectin was associated with a lower prevalence of epilepsy. METHODOLOGY/PRINCIPLE FINDING...

Iodised oil is traditionally based on the fatty acids (FAs) of the poppyseed, an expensive commodity. An equipotent but cheaper vehicle would be welcome. Iodination of rapeseed oil yields a product (Brassiodol) with a total iodine content of 376 mg/mL. Brassiodol has been compared with the poppyseed-based Lipiodol in two villages in Chad in the west African goitre belt. A 2 mL dose of Brassiodo...

Measurement of the rate of accumulation of radioiodine by the thyroid gland is of considerable clinical value, since in most instances an avid uptake of radioiodine may be correctly assumed to be due to a high rate of uptake of stable iodide by the thyroid. This measurement, expressed as a percentage of the administered radioiodine dose accumulated per unit time by the thyroid, does not give a ...

Iodine deficiency has been shown to have high prevalence in Iran despite sufficient iodine supplementation. Zinc deficiency may also contribute to the pathogenesis of endemic goiter. The aim of this study was to compare serum zinc level in Iranian school children with and without goiter. A cross-sectional study was performed among urban children aged 8-12 years in city of Kerman, Iran. A multis...

The present study was undertaken to assess the state of iodine nutrition of the representative population, consumption pattern of cyanogenic plant food that generally interfere with iodine nutrition, and to evaluate whether there is any interrelation between iodine and thiocyanate intake and their excretion pattern among school children in goiter endemic subHimalayan tarai region. A total of 56...

BACKGROUND In programs to control iodine deficiency disorders (IDD), sustainability is a major concern. IDD has recently recurred in countries where salt iodization programs have lapsed. OBJECTIVE The objective of the study was to describe the evolution of thyroid dysfunction after the discontinuation of salt iodization in a cohort of children in an area of severe endemic goiter. DESIGN Mor...

OBJECTIVE To determine how iodine deficiency and endemic goitre disappeared in Britain. DESIGN Review of surveys of endemic goitre and iodine nutrition. MAIN RESULTS Endemic goitre was widespread in Britain but has declined, most notably since the 1960's. Its disappearance was probably due to changes in farming practice, especially iodine supplementation in dairy herds which has resulted in...

At the time after the Second World War, endemic goiter was present in most parts of Croatia with a prevalence of more than 50% and presence of cretinism. In the village of Rude near Zagreb, goiter was detected in 85% of school children with 2.3% of cretins in the village population. In 1953 the first regulation on obligatory salt iodination, requiring 10 mg of potassium iodide (KI) per kg of sa...
