Waardenburg Syndrome is a rare autosomal genetic disorder that has possible bright blue eyes as one of its qualifying criteria, along with possible deafness (common). Actually, the cause of the blue eyes is a form of albinism that may include patches of non-pigmented skin or forehead hair, regardless of ethnicity.

There are four types of Waardenburg Syndrome, with a mix of possible characteristics as the determinant. Medical challenges increase with type. The boy in the picture is displaying two major symptoms of type 1; bright blue eyes and dystopia canthorum, a condition where the inner corners of the eyes are set more widely apart, but with normally distanced eyes. ...

In 1943, Walt Disney helped combat malaria by making an animated film called The Winged Scourge. This short film starred the seven dwarfs and taught children that mosquitoes transmit malaria, which is a very bad disease. While not specifically mentioned in the film, malaria is caused by several species of the protozoan Plasmodium, of which Plasmodium vivax and Plasmodium falciparum are the most common. The most serious infections involve P. falciparum, which causes a higher incidence of complications and death. The short film advocated the killing of mosquitoes to stop the disease.


Luckily, by 1951, malaria was finally eliminated in the United States (eliminated means that no new cases arose in the country for 3 years). Today, oral chloroqui ...

Patients with urinary tract infections can drink cranberry juice to make their urine more acidic.

In the early 1900s, the disease pellagra was widespread in the United States, especially in southern states. Individuals with pellagra were weak, and they developed diarrhea, a skin rash, and mental confusion. Each year, thousands of Americans died from this dreaded illness. In 1914 the U.S. surgeon general assigned Joseph Goldberger, a physician who worked in a federal government laboratory, to study pellagra. Most medical experts thought pellagra was an infectious disease because it often occurred where people lived in close quarters, such as prisons, orphanages, and mental health institutions. Goldberger knew from his previous research that infectious diseases usually spread through a population by close physical contact. While investiga ...
