什麼是蜂箱(hives)？

Hives are slightly elevated, reddish, itchy, multiple lesi*** occurring on the skin. These occur commonly as a result of an allergy. With allergen exposure, it  causes mast cells to release histamine which is a chemical mediator stored inside mast cells. Histamine causes dermal edema giving rise to this typical appearance. Hives occur very rapidly, and it commonly occurs with food allergy. However, some other causes such as pressure and sunlight can cause hives rarely in a certain vulnerable group of people. Hives disappear spontaneously, and they are self-limiting. If hives are associated with life threatening allergic reacti*** such as angioedema (edema around the mouth) or anaphylaxis, more medical attention is required. Antihistamines can be used for symptomatic relief. Sometimes, a short cause of steroids may be required to relieve symptoms. It is important to avoid exposure to known allergens/causes to prevent recurrences of hives.

什麼是皮疹(rashes)？

Rashes are a category of skin disease causing skin damage. Rashes can take many appearances such as macular, popular, maculopapular, exfoliative, plaque forming, etc. Some rashes are inherent diseases affecting the skin such as Eczema and Psoriasis. Some rashes associated with other systemic diseases such as autoimmune diseases, infecti***, etc. Identification of the typical appearance and the distribution of rashes guide in the diagnosis of associated systemic diseases. Dermatology is the specialty in medicine with regard to the management of rashes. When the rash is severe, affecting deep layers of the skin, it can lead to dehydration, hypothermia, and infecti***. Rashes need proper attenti*** by a doctor. Some rashes are short lasting and completely curable. Examples for these are infection associated rashes such as viral exanthema. On the other hand, some rashes are relapsing and not completely curative. Examples are psoriasis and eczema. However, these rashes can be controlled satisfactorily by offering proper treatment.  Treatment for rashes includes local applicati*** such as loti***, creams, and ointments as well as oral treatments.
