Poison Ivy Rash
A poison ivy rash is a type of skin irritation called allergic contact dermatitis. Poison ivy rash is caused by a sensitivity to an irritant found in poison ivy and similar toxic plants, such as poison oak and poison sumac. Each of these plants contains an oily resin called urushiol (u-ROO-she-ol) that can irritate the skin and cause a rash.
Although the itching from a poison ivy rash can be quite bothersome, the good news is that a poison ivy rash or one caused by poison oak or poison sumac generally isn’t serious. Poison ivy rash treatment consists of self-care methods to relieve itching until the reaction disappears.
Signs and symptoms of a poison ivy rash include:
- Redness
- Itching
- Swelling
- Blisters
Contact Lens Induced Infections
The primary source of bacterial infections is poor contact lens cleansing regiments & poor hygiene of the patient. Patients who have existing blepharitis or dry eyes are more liable to infections, further complicating the situation. Disposable & frequent replacement contact lenses were developed to combat these problems. Other types of contact lens induced infections include sterile corneal infiltrates, acanthamoebic keratitis, & fungal keratitis.
The most commonly found contact lens induced infections are infectious bacterial keratitis & ulcers that are related to P. aeruginosa. P. aeruginosa keratitis can lead to corneal perforation & ultimate loss of vision. Sterile keratitis is mote common with disposable extended wear lenses, where as infectious keratitis is more common with re-usable extended wear contact lenses. Read more

What is Uvula?
There is an organ in our throat known as the uvula.
It is a conic projection, which pops out from the posterior edge of the soft palate. It is made up of connective tissue and some muscle fibre.
Most physicians feel that the uvula is a vestigial anatomical structure (i.e. a structure which doesn’t have any significant function but has a remnant of an evolutionary modification). However there are a few who feel that the uvula plays a crucial role in speech and swallowing by participating in closing the nasopharynx during such activities.
Many surgeons have observed that the common complication of removing uvula is pharyngeal dryness. This thereby implies that uvula plays an active role in keeping the throat moist and well lubricated.
At times, especially following a surgery, the mucous membrane of the uvula may swell increasing the size of the uvula. As a result of increase in its size, the uvula may touch the throat or the tongue, creating a sensation of gagging, choking or tickling. Read more
