Conjunctivitis
The term conjunctivitis refers to any inflammatory condition of the membrane that lines the eyelids and covers the exposed surface of the sclera, and is the most common cause of "red eye" or "pink eye" (Abbott pp). Most often the etiology can be determined by a careful history and an ocular examination, however, culture is sometimes necessary to establish the diagnosis or to guide therapy (Abbott pp). The most common causes of conjunctivitis are bacteria and viruses (Abbott pp). When severe, bilateral, purulent conjunctivitis is present in a sexually active adult or in a neonate three to five days postpartum, then Neisseria infection should be suspected (Abbott pp). Conjunctivitis that is caused by Chlamydia trachomatis or Neisseria gonorrhoeae requires aggressive antibiotic therapy, however, conjunctivitis due to other bacteria is usually self-limited (Abbott pp). Chronic conjunctivitis is most often associated with blepharitis, recurrent styes or meibomianitis, and treatment requires good eyelid hygiene and the application of topical antibiotics as determined by culture (Abbott pp). The discomfort with viral or bacterial conjunctivitis can be soothed by applying warm compresses using a clean cloth soaked in warm water to closed eyes (Conjunctivitis pp). Allergic conjunctivitis is characterized by severe itching and allergen exposure and is generally treated with topical antihistamines, mast-cell stabilizers or anti-inflammatory agents (Abbott pp).
Cellular infiltration and exudation characterize conjunctivitis on a cellular level. Classification usually is based on cause, including viral, bacterial, fungal, parasitic, toxic, chlamydial, chemical, and allergic agents. It also can be based on age of occurrence or course of disease. Etiology often can be distinguished on clinical grounds. In keratoconjunctivitis,
an associated corneal involvement is present
(Silverman pp).
The conjunctiva is a thin, translucent, relatively elastic tissue layer with both bulbar and palpebral portions, the bulbar portion fines the outer aspect...
However, one cannot develop the vaccine before the outbreak occurs. From development to commercial production of the vaccine would take approximately three months after a pandemic has been declared (WHO, 2008). The vaccine developed must be matched exactly to the disease, or it will prove ineffective. The development of a vaccine that is not effective is a waste of money, resources, and will do nothing to help stop the
Still another option is immunotherapy. In 2000, the Immunotherapy Committee of the American Academy of Allergy, Asthma, and Immunology compared the costs of medication and the single-injection allergen immunotherapy for allergic rhinitis. It found that the cost of medications is much greater. Allergen immunotherapy is generally safe and adverse reactions to are rare (Huggins 2004).

Air Pollution The air that surrounds us is a mixture of 78% nitrogen; 21% oxygen; less than 1% of carbon dioxide, argon, and other gases; and varying amounts of water vapor. Any other particles, gases or unoriginal constituents hanging in the air which are not part of its original composition are called 'Pollutants' and this kind of air is called Polluted Air. Even inhaling small amounts of such air pollutants can

Chlamydia Trachomatis Scientific Details Life Cycle of Chlamydia Trachomatis in the Human Body Infection & Symptoms Diagnosis Screening Prevention of Chlamydia Infection Chlamydia trachomatis, a bacterium, has a tendency to infect the columnar epithelium of the cervix, the urethra, and the rectum. Apart from genital areas the bacteria can affect and infect other areas of the body like the lungs and the eyes. This bacterium is one of the prime sources of most of the sexually transmitted
