OBJECTIVE To compare use of chlorhexidine with use of iodine for preoperative skin antisepsis with respect to effectiveness in preventing surgical site infections (SSIs) and cost. METHODS We searched the Agency for Healthcare Research and Quality website, the Cochrane Library, Medline, and EMBASE up to January 2010 for eligible studies. Included studies were systematic reviews, meta-analyses,...

INTRODUCTION Iodine is considered to be an essential micronutrient in pregnant women. Iodine placental transport to the embryo-fetus is essential for hormone synthesis and is crucial for nervous system development. However, the relationship between iodine intake and placental weight and its potential implications for the newborn have not been studied. MATERIAL AND METHODS Iodine intake was an...

Background and Aim: Bacterial colonization occurs following contamination of impression materials with blood and saliva. However, not all disinfecting agents are compatible with the impression materials and may cause changes in the resultant casts. The purpose of this study was to assess the impact of various immersion time of addi-tion silicon impressions in different disinfecting solutions on...

Although the roster of coulometric titrations no\\' includes many reactions of classical titrimetry'. the lIse of cl,ectrogeneratecl +2 tin as a coulometric titrant has not previously been reported. We have found that in an acidic bromide medium +4 tin (probably SrlBr6-2) is reduced to the' +2 state (probably SnBr4-2) with 100% current efficiency' at a gold cathode. The formal potential of the ...

The objective of this research was to investigate the effect heating temperature on quality parameters avocado and peanut oils subjected heating. Vegetable were heated at varying temperatures (110, 140, 170, 200 230�C for 30 min) follow alterations. Levels peroxide value, iodine thiobarbituric acid reactive substances, total polar compounds, refractive index, free acidity, fatty acids compositi...

The react ion rate of the cou lomet r ic variant of the Karl-Fischer t i t ra t ion reac t ion (in which electrolyt ical ly generated t r i iodide is used as ox idan t instead of iodine) has been measured in methanol . The react ion is first order in water , sulfur d ioxide and t r i iodide, respectively. For pH < 5 the react ion rate cons tan t decreases logari thmical ly wi th decreasing pH. ...

BACKGROUND Globally, more than two billion people are at risk of iodine deficiency disorders, 32% of which are school children. Iodine deficiency has been recognized as a severe public health concern in Ethiopia, however little is known about the problem. Therefore, this study aimed to assess the prevalence of goiter and associated factors among school children (6 to 12 years) in Dabat District...

When young children do not receive adequate amounts of the micronutrient iodine in their diet, their growth and cognitive development can be impaired. Nearly every country in the world has programs in place to track iodine intake and provide supplemental iodine if needed, usually in the form of fortified salt. The iodine nutrition status of a population can be tracked by monitoring iodine level...
