A critical evaluation of povidone-iodine absorption in thermally injured patients.

Abstract: Povidone-iodine ointment is a widely used topical antimicrobial agent in thermally injured patients. In 17 patients with burns ranging from 4 to 85% TBSA this agent was applied to both partial- and full-thickness burns. Peak serum iodine levels in patients treated within 24 hours of injury ranged from 595 to 4,900 micrograms per dL. The amount of iodine absorbed was directly related to the size of the burn. Serum iodine levels continued to rise until the drug was discontinued and remained elevated for as long as 7 days after discontinuance. Iodine excretion was directly related to renal function. The highest serum and lowest urinary iodine levels were present in patients who developed renal failure. Thyroid function was not affected by drug usage. A proven cause-and-effect relationship between the elevated serum iodine attributed to the absorption of povidone-iodine and metabolic acidosis, hypernatremia, and hyperosmolarity was not established. Close monitoring of the patient's fluid and electrolyte balance is imperative during drug usage. The drug is contraindicated in any patient with impaired renal function. The high serum levels of this inorganic ion imply potential toxicity, but clinical evidence of cell or organ toxicity is as yet undetermined.

Iodide and iodate effects on the growth and fruit quality of strawberry.

Abstract: Iodine deficiency is an environmental health problem affecting one-third of the global population. An iodine biofortification hydroponic experiment was conducted to explore the iodide and iodate uptake characteristics of strawberry plants, to measure the dosage effects of iodine on plant growth and to evaluate the influence of I? or IO3? application on fruit quality. RESULTS After biofortification, the iodine contents of the fresh strawberry fruits were 600?4000 µg kg?1, covering the WHO dietary iodine allowance of 150 µg · day?1 for adults. The iodine uptake of the strawberry plants increased with increasing I? or IO3? concentration of the culture solution. At the same iodine concentration, the iodate uptakes of various plant organs under I? treatments were apparently more than those under IO3? treatments. Low-level exogenous iodine (I? ≤ 0.25 mg L?1 or IO3? ≤ 0.50 mg L?1) not only promoted plant growth and increased biomass per plant, but also improved fruit quality by enhancing the vitamin C and soluble sugar contents of the strawberry fruits. Nevertheless, excessive exogenous iodine inhibited plant growth and reduced biomass per plant. IO3? uptake apparently increased the total acidity and nitrate content of the fruits, reducing the quality of the strawberry fruits. Conversely, I? uptake obviously decreased the total acidity and nitrate content of the strawberry fruits, improving the fruit quality. CONCLUSION The strawberry can be used as a target crop for iodine biofortification. Furthermore, applying an appropriate dose of KI can improve the fruit quality of the strawberry plants. ? 2016 Society of Chemical Industry
