Pink Eye - Conjunctivitis is swelling (inflammation) or infection of the membrane lining the eyelids (conjunctiva). There are many causes of conjunctivitis. Viruses are the most common cause. "Pink eye" refers to a viral infection of the conjunctiva. These infections are especially contagious among children. Newborns can be infected by bacteria in the birth canal. This condition is called ophthalmia neonatorum.
Ear Infections - Ear infections are one of the most common reasons parents take their children to the doctor. While there are different types of ear infections, the most common is called otitis media, which means an inflammation and infection of the middle ear. The middle ear is located just behind the eardrum. An acute ear infection is a short and painful ear infection.
Swimmer’s Ear - Swimmer's ear is inflammation, irritation, or infection of the outer ear and ear canal. The medical term for swimmer's ear is otitis externa. Swimmer's ear may be acute or chronic. Swimmer's ear is fairly common, especially among teenagers and young adults. It is occasionally associated with middle ear infection (otitis media) or upper respiratory infections such as colds.
Sinus Infections - Sinusitis refers to inflammation of the sinuses that occurs with a viral, bacterial, or fungal infection. The sinuses are air-filled spaces in the skull (behind the forehead, nasal bones, cheeks, and eyes) that are lined with mucus membranes. Healthy sinuses contain no bacteria or other germs. Usually, mucus is able to drain out and air is able to circulate. When the sinus openings become blocked or too much mucus builds up, bacteria and other germs can grow more easily.
Sore throat - Pharyngitis, or sore throat, is discomfort, pain, or scratchiness in the throat. It often makes it painful to swallow. Pharyngitis is caused by swelling (inflammation) of the pharynx, which is in the back of the throat, between the tonsils and the voicebox (larynx). Most sore throats are caused by a viral infection, such as the cold or flu. Some viruses can cause specific types of sore throat, such as coxsackie infection or mononucleosis. Bacteria that can cause pharyngitis include Group A streptococcus, which leads to strep throat in some cases.
Thrush - Thrush is a yeast infection of the mucus membrane lining the mouth and tongue. Thrush is caused by forms of a fungus called Candida. A small amount of this fungus lives in your mouth most of the time. It is usually kept in check by your immune system and other types of germs that also normally live in your mouth. Thrush is commonly seen in infants. It is not considered abnormal in infants unless it lasts longer than a couple of weeks.
