The history of urticaria is a fascinating account of mankind gradually growing to understand human diseases. The process starts with the many different names this disease has been given to in the past. The school of Hippocrates in 4th century BC recognized urticaria with nettles. The roman school instead focused on its burning sensation and is where Plinius named it uredo. In the 10th century, Hali Ben Abbas used the name essera because it means mountain or elevation, alluding that the welt is above skin level. In 18th century, Zelder called it urticatio, and in 1792, urticaria was the accepted name. A couple of words have been made during recent times but they did not clearly distinguish the disease from the other skin diseases. Some writings of the 16th century can be rediscovered indicating that strawberries and shellfish were implicated as a cause for urticaria. There were many other theories that tried to explain the causes of the formation of these raised welts. Many stated that certain foods were the reason but slowly doctors discovered that it is not just food that triggers urticaria.
Urticaria is now commonly known as hives, it is a common allergic reaction that makes the skin form raised red itchy welts. They can also burn or sting. Anyone can be susceptible to hives since it is a very common condition. Hives form when histamine, a chemical, is released by mast cells. Histamine is usually released with an allergic reaction and it acts by causing the blood vessels to leak fluid into the nearby tissues causing skin to puff up like a mosquito bite. Releasing histamine does not need to be from an allergic reaction though; there are other circumstances where it can be released. They are usually harmless and can last up to ha...

Hidradenitis Suppurativa (HS) is a chronic skin condition that features lumps under the skin that range from pea-sized to marble sized. This condition is also known as acne inversa. Hidradenitis Suppurativa is NOT contagious. This condition usually occurs where skin rubs together such as between the buttocks, under the breasts, the armpits and the groin. Most of these lumps tend to be very painful and when they break open they often produce malodorous pus.
One measure they had was that of the “red cross”. This is where they would paint a red cross on the doors of people who were diagnosed with the plague. I think this would have worked because it would let people know who had the plague, so that they could avoid falling ill themselves.
Xeroderma Pigmentosum was discovered by Hebra and Kaposi in 1874. Kaposi coined the term Xeroderma Pigmentosum eight years later, using the name to describe the symptom of dry, pigmented skin. Further research began after this, leading to the discovery that the disease was caused by a generic mutation instead of a virus or bacteria.
From 1997 to 2008 the number of American children that have some form of nut allergy has tripled. Peanut allergies are considered one of “Big 8” food allergies that accounts for 90% of allergies which includes 3 million Americans out of the 21 million Americans that suffer from some form of allergy. Less than 21% of those individuals with peanut allergies will outgrow it. Peanut allergies account for the most common food related deaths. Four out of every 100 children have some form of food allergy. If an allergy is going to surface it will effect a child between 12 and 14 months of age this is why child care environments are the most vulnerable. Peanut allergies affect about 5% within this age group. I was surprised with the various names and different items that peanuts can be found in. Peanut
What are these red patches of skin on my body that I can’t ever help from scratching?

The first known use of dermatology was established in 1819 and only in the 1930’s did its practice become more widely accomplished, known and sought after. (“Dermatology” 2014) Since then it has extensively evolved and changed and been able to provide services for women and men around the world. Originally being a part of the medicine field can now be considered a division of the beauty industry due to availability of services and treatments for aesthetic, pampering purposes, rather than just originally founded for medical issues of resolving skin disorders and diseases. Dermatology being defined as ‘a branch of medicine dealing with the skin, its structure, functions and diseases’ (“Dermatology” 2014) now offers many professions one being a dermatologist, whic...
Rosacea is a common skin disorder of the facial skin that affects well over 16 million Americans without them knowing the condition is present. It appears as red discoloration or bumps on the surface of the skin. Over time, the redness becomes brighter and more persistent and blood vessels begin to appear on the skin. The cause of this condition is unknown, but could be caused by hereditary or environmental factors. A number of these same factors can trigger the rosacea and send blood rushing into the surface of the skin. These factors can include alcohol, extreme temperatures, sunlight/wind, emotions, exercise, and certain cosmetic items. All of these factors combined could cause a flare up of the disorder at any given time.

In many cases, the symptoms of Acne and Rosacea turn to be identical as both conditions are observed on the skin. The skin acne is detected due to effects of environmental conditions, usage of harsh chemicals, and direct skin exposure to the sun. On the other hand, the causes of Rosacea are the abnormalities in blood vessels, uncontrolled H. pylori bacteria, light skin color and it can be inherited as well. With so many differences, their treatments & diagnosis are also different in the field of Aesthetics. Mainly, after going through the laser treatment for Rosacea in Providence, the person can get permanent relieve from this type of chronic and inflammatory disease.
In mild cases, swelling of lips, eyes or face occurs along with hives, rash, tingling of mouth and vomiting accompanied with abdominal pain. Nevertheless, in extreme conditions the former symptoms may be accompanied by noisy breathing, wheezing, hoarseness and unconsciousness. Lloyd & Sisman,2013. Managing the threat: People/ children who have been diagnosed with a threat to anaphylaxis need to strictly follow the Action Plan (Australasian Society of Clinical Immunology & Allergy, 2012) as suggested by their medical practitioner. There is no preventive medication developed for this condition so far.
A urinary tract infection is a very common infection that can happen to anybody. A urinary tract infection usually occurs when bacteria enters the urethra and multiples in the urinary system. The Urinary tract includes the kidneys, the thin tubes that carry urine from the kidneys to the bladder (ureters), and the main tube that carries the urine from the bladder (urethra). Women, men, and children are all immune to this infection. Women have the highest chances of getting it. In the Urinary tract, the main links of the ureters help get rid of any bacteria that tries to enter the urine, and the bladder helps prevent urine from backing up into the kidneys.
In the US and Canada it is estimated that 5.7 million bats have died because of White nose syndrome (wisconbio,4). Bats are a very helpful animal in our area, but sadly they are being wiped out. Bats in Wisconsin need to be protected or they could eventually go extinct.
Patients who usually have allergies suffer from many symptoms due to the allergic reaction(s). Normally, your immune system protects you against invading agents such as bacteria and viruses. Otherwise harmless allergens (allergy-producing substances) cause your body to react as if they were dangerous invaders. In effect, your immune system is responding to a false alarm.
