Erythema toxicum neonatorum (also known as toxic erythema of the newborn) is a harmless red rash that appears on the skin of newborns. This rash goes away on its own and has no symptoms. It has often been likened to the appearance of a fleabite on the skin. Erythema toxicum is an extremely common rash that does not require any treatment, as it will spontaneously go away in 5–7 days. The cause of this rash is unknown.
Chickenpox (varicella) is an infectious disease caused by the varicella-zoster virus that goes away on its own. Infection spreads among humans through fluids from the airways, such as from coughing and sneezing, with non-infected household members at high risk of becoming infected as well. The development (incubation) period is 14–16 days, and the first sign of disease is a rash. People are considered contagious for 2–5 days before the onset of skin lesions and for 6 days after the last series of rashes have appeared.The most common complication is infection of lesions with bacteria. Rare complications include lung infection (pneumonia) or brain infection (encephalitis). Children who have weak immune systems, eczema, or recent sunburns have more severe symptoms. Because the virus remains resting (latent) in the parts of nerves that are near the spinal cord (nerve roots) for life, about 1 in 10 adults will get shingles (zoster) when the virus reappears, usually under conditions of stress to the body.After having chickenpox, a person is usually immune for life, although reinfection is possible.
Flashes and floaters describes a condition that comes from changes in the back chamber of the eye (the posterior chamber, also known as the vitreous cavity). The posterior chamber is filled with a material called vitreous (the vitreous body) which, at birth, is jelly-like in consistency. With normal aging, the vitreous begins to break down into a mixture of clear liquid and pieces of debris, which appear as specks of dust, lint, lines, branching twigs, or spiders. Ultimately, the vitreous becomes so loose that it often detaches from its normal attachments to the retina. When this occurs, it is called a posterior vitreous detachment (PVD). After the posterior vitreous detachment has occurred, one will often see a fairly large, ring-like floater. About 15% of people with a posterior vitreous detachment also have an associated retinal tear, which requires medical attention.There are 3 rather uncommon conditions that can cause floaters, which are: Asteroid hyalosis – a benign condition where there are spherical white bodies in the vitreous; it is thought to be related to diabetes and high cholesterol levels. Synchysis scintillans – a degenerative condition with cholesterol crystals in the vitreous, usually due to previous eye injury or internal eye inflammatory disease. Amyloid degeneration – a very rare degenerative condition with amyloid deposits in the vitreous and elsewhere in the body.The flashes of light we see in this normal aging process can be either in the form of lightening bolts, shooting stars, sparks, or an arc of light to the side. The latter is most often what occurs when the vitreous has become so loose that it sloshes around and, when it strikes the retina (the electric membrane of the eye), it sets off an arc of light to the side of vision. Normally, it is either the vitreous tugging on the retina or bouncing against it that causes the sparks and shooting stars phenomenon. But flashes and floaters may have more serious causes and consequences if the floaters are from blood, inflammatory or infectious processes within the eye, torn retinal tissue, or associated with a retinal detachment. Flashes may also occur with migraine headaches.
In Florida this year, nine people have died and another 27 reported infections from Vibrio vulnificus bacteria, which lives in salty water. Such infections are rare, but cases have steadily risen in Florida since 2008, when 15 cases and five deaths were reported. Vibrio vulnificus are naturally occurring bacteria in saltwater, which are more commonly found in stagnant and brackish waters with lower salinity levels, such as estuaries and inlets.
Measles cases are on the rise in 2013 with recent outbreaks in several states. The Centers for Disease Control and Prevention reported 159 cases of measles from January to August, 2013. Most cases were in persons who were unvaccinated (131 [82%]) or had unknown vaccination status (15 [9%]). The biggest outbreaks were in New York, North Carolina and Texas. Measles had been virtually eliminated through vaccination in 2000. But the measles virus continues to be imported to the U.S. from other countries where vaccination rates are much lower and then spread through populations in the U.S. where vaccination rates are low.
Story from Krista I’m not a sick person. In fact, I rarely go to the doctor. So when I came down with a 104°F fever, headache, and sore throat during a summer weekend seven years ago my biggest concern was for my baby; I was just over seven months pregnant.
With concerns about the H1N1 swine flu and other infectious diseases, many schools are adding hand sanitizer to their list of required supplies this year. But this policy leads to several questions: What should we look for when selecting a hand sanitizer? Do these products really work? If they do work, will using them create drug-resistant organisms? No doubt some of you have seen concerning e-mail reports of children becoming gravely ill after ingesting hand sanitizer. I have two school-aged children, and I decided to find the answers before I set out to buy our school supplies.
When image contributors on opposite sides of the country submitted photographs to VisualDx of patients with dark purple lesions of the ears, cheeks, and face, we realized we were witnessing the emergence of a serious public health concern.

Diagnosis Synopsis Cocaine Levamisole Toxicity : Cocaine contaminated with levamisole has been detected in the United States since 2003, and the incidence of toxicity caused by this contamination has been increasing rapidly since 2008. Use of cocaine that has been adulterated with levamisole can lead to a constellation of symptoms including agranulocytosis, neutropenia, and a vasculitis-like purpuric tender skin eruption. The most common sites of purpura are the external ears and cheeks. The purpura is generally followed by skin necrosis, but resolves several weeks after cessation of cocaine use. Recurrent use of contaminated cocaine generally results in recurrent skin eruptions.
What bit me? Bedbugs. Scabies. Fleas. Spiders. Ticks. Lice… All can cause rashes, itching, and a lot of worry. The recent surge in bedbugs in eastern cities has everyone talking about how to find and kill bed bugs. But if you have a new rash or itchy red bumps, how do you know if bed bugs are the cause? Maybe your skin problem is not even related to insects or bugs and is caused by something different altogether. Many skin disorders like eczema (atopic dermatitis) and/or infections of your pores (known as folliculitis) can have an itchy rash, and these conditions have nothing to do with biting bugs, although people often wrongly assume that these common skin conditions are “bug” related.
Measles has been on the rise in the US. This is due, in part, to concerns regarding the safety of the MMR vaccine. Although recent research has provided strong evidence against the association of autism with MMR vaccine administration, some parents still choose to request one or more vaccine exemptions on the basis of personal beliefs for their child to attend day care or school.
