Children infants

The symptoms of vitamin E deficiency in animals are numerous and vary from species to species (13). Although the deficiency of the vitamin can affect different tissue types such as reproductive, gastrointestinal, vascular, neural, hepatic, and optic in a variety of species such as pigs, rats, mice, dogs, cats, chickens, turkeys, monkeys, and sheep, it is generally found that necrotizing myopathy is relatively common to most species. In humans, vitamin E deficiency can result from poor fat absorption in adults and children. Infants, especially those with low birth weights, typically have a vitamin E deficiency which can easily be corrected by supplements. This deficiency can lead to symptoms such as hemolytic anemia, reduction in red blood cell lifetimes, retinopathy, and neuromuscular disorders. 

Children Infants and children (21 days to 3.3 years of age) with symptomatic gastroesophageal reflux have been treated with metoclopramide at a dosage of 0.5 mg/kg/day symptoms improved, the duration of the disease was shortened, and surgery was avoided. 

Children Infants A syndrome of apparent CNS depression, characterized by stupor and flaccidity, occasionally coma, and deep respiratory depression, has been reported in young infants in whom streptomycin dosage had exceed the recommended limits. Do not giye infants streptomycin in excess of the recommended dosage. 

Weight is so important a covariate that in models involving children, infants, or neonates weight is often built into the model from the very beginning. 

Too much phenylpyruvic acid causes phenylketonuria (PKU disease), which can lead to mental retardation in growing children. Infants are routinely screened for PKU disease within a few days of birth. PKU disease cannot be cured, but is controlled by restricting the dietary intake of foods, such as meat, that are rich in L-phenylalanine. 

Chronic toxic symptoms (hypervitaminosis A) may occur in adults who receive doses of vitamin A in excess of 50,000 lU daily over a prolonged period. Lesser doses will produce symptoms in children infants who receive 18,500 lU daily may show signs of toxicity within 12 weeks. Acute toxicity occurs in adults who are given massive doses of 2 to 5 million lU daily, and in infants from doses as low as 75,000 to 300,000 lU daily. Vitamin C can help prevent the harmful effects of vitamin A toxicity. When excess intake of vitamin A is discontinued, recovery is usually rapid and complete in some cases, the toxicity symptoms disappear within 72 hours.
