Asthma: A common disorder in which chronic inflammation of the bronchial tubes (bronchi) makes them swell, narrowing the airways. Asthma involves only the bronchial tubes and does not affect the air sacs (alveoli) or the lung tissue (the parenchyma of the lung) itself. See the entire definition of Asthma
Bacterial: Of or pertaining to bacteria. For example, a bacterial lung infection.
Breast milk: Milk from the breast. Human milk contains a balance of nutrients that closely matches infant requirements for brain development, growth and a healthy immune system. Human milk also contains immunologic agents and other compounds that act against viruses, bacteria, and parasites. Since an infant's immune system is not fully developed until age 2, human milk provides a distinct advantage over formula. See the entire definition of Breast milk
Breathing: The process of respiration, during which air is inhaled into the lungs through the mouth or nose due to muscle contraction, and then exhaled due to muscle relaxation.
Dizziness: Painless head discomfort with many possible causes including disturbances of vision, the brain, balance (vestibular) system of the inner ear, and gastrointestinal system.

Head lice: Pediculus humanus capitis, parasitic insects found on the heads of people. Head lice are most often found on the scalp behind the ears and near the neckline at the back of the neck. The lice hold onto the hair with hook-like claws at the end of each of their six legs. Head lice are rarely found on the body, eyelashes, or eyebrows. These insects lay their sticky, white eggs on the hair shaft close to the root, while hatched lice stay mostly on the scalp. Head lice infection is very common and easily acquired by coming in close contact with someone who has head lice, infested clothing, or infested belongings. Preschool and elementary school children and their families are most often infested. See the entire definition of Head lice
Infant: A child up to 2 years (24 months) of age. See the entire definition of Infant
Infection: The growth of a parasitic organism within the body. (A parasitic organism is one that lives on or in another organism and draws its nourishment therefrom.) A person with an infection has another organism (a "germ") growing within him, drawing its nourishment from the person. See the entire definition of Infection

Medical history:1. In clinical medicine, the patient's past and present which may contain clues bearing on their health past, present, and future. The medical history, being an account of all medical events and problems a person has experienced, including psychiatric illness, is especially helpful when a differential diagnosis is needed. 2. The history of medicine.
Mouth:1. The upper opening of the digestive tract, beginning with the lips and containing the teeth, gums, and tongue. Foodstuffs are broken down mechanically in the mouth by chewing and saliva is added as a lubricant. Saliva contains amylase, an enzyme that digests starch. 2. Any opening or aperture in the body.

Poison: Any substance that can cause severe distress or death if ingested, breathed in, or absorbed through the skin. Many substances that normally cause no problems, including water and most vitamins, can be poisonous if taken in too large of a quantity. Poison treatment depends on the substance: if there are treatment instructions on the substance's container and you are sure it contained no other item, follow those directions immediately. Always contact your nearest Poison Control Center if you are concerned about possible poison ingestion.
Poison Control Center: Special information centers set up to inform Americans about how to respond to potential poisoning. These centers maintain a database of poisons and appropriate emergency treatment. The Poison Control Center in your area should be listed with other community service numbers in the front of your telephone book, and can also be reached immediately through any telephone operator. See the entire definition of Poison Control Center
Pregnant: The state of carrying a developing fetus within the body. See the entire definition of Pregnant
Prescription: A physician's order for the preparation and administration of a drug or device for a patient. A prescription has several parts. They include the superscription or heading with the symbol "R" or "Rx", which stands for the word recipe (meaning, in Latin, to take); the inscription, which contains the names and quantities of the ingredients; the subscription or directions for compounding the drug; and the signature which is often preceded by the sign "s" standing for signa (Latin for mark), giving the directions to be marked on the container.
Pubic lice: Parasitic insects found in the genital area of humans. Pubic lice are usually spread through sexual contact. Rarely, infestation can be spread through contact with an infested person's bed linens, towels, or clothes. A common misbelief is that infestation can be spread by sitting on a toilet seat. This is not likely, since lice cannot live long away from a warm human body. Also, lice do not have feet designed to walk or hold onto smooth surfaces such as toilet seats. Infection in a young child or teenager may indicate sexual activity or sexual abuse. See the entire definition of Pubic lice
Pus: A thick whitish-yellow fluid which results from the accumulation of white blood cells (WBCs), liquified tissue and cellular debris. Pus is commonly a site of infection or foreign material in the body.
Rash: Breaking out (eruption) of the skin. Medically, a rash is referred to as an exanthem.
Topical: Pertaining to a particular surface area. A topical agent is applied to a certain area of the skin and is intended to affect only the area to which it is applied. Whether its effects are indeed limited to that area depends upon whether the agent stays where it is put or is absorbed into the blood stream.
Vagina: The muscular canal extending from the cervix to the outside of the body. It is usually six to seven inches in length, and its walls are lined with mucus membrane. It includes two vaultlike structures, the anterior (front) vaginal fornix and the posterior (rear) vaginal fornix. The cervix protrudes slightly into the vagina, and it is through a tiny hole in the cervix (the os) that sperm make their way toward the internal reproductive organs. The vagina also includes numerous tiny glands that make vaginal secretions. See the entire definition of Vagina
Head lice infection is called pediculosis. Lice are parasites that feed on blood and can be found on the scalp and hair of infected people. Signs and symptoms of head lice infestation include a tickling sensation, itching, and sores on the head. Head lice may be eliminated with various over-the-counter shampoos and washing all clothing and bed linens in the hot water cycle. Combs and brushes should be disinfected, and the floor and furniture should be vacuumed.
Leishmaniasis is a disease caused by the bite of an infected sand fly. The most common types of leishmania infection are cutaneous and visceral leishmaniasis. Leishmaniasis is found mainly in the subtropics and tropics. Symptoms and signs of cutaneous leishmaniasis include skin sores with a raised edge and central crater, while those with visceral leishmaniasis usually have fever, weight loss, and an enlarged liver and spleen.
Typhus is a disease caused by Rickettsia bacteria. Symptoms and signs include fever, headache, nausea, vomiting, diarrhea, and rash. Antibiotics are recommended as the treatment for endemic and epidemic typhus infections.
Typhus is a bacterial disease; there are two types termed
endemic and epidemic.
Typhus has a long and deadly history, especially epidemic
typhus.
Typhus is caused by bacteria. Rickettsia prowazekii causes epidemic
typhus. Rickettsia typhi and, occasionally, R. felis cause endemic typhus and are
transmitted to humans by vectors such as lice (mainly epidemic) and fleas (mainly
endemic).
Risk factors include visiting or living in areas where rats, mice, and
other animals have high populations (for example, disaster areas,
poverty-stricken areas, refugee camps, jails) where vectors such as fleas and
lice can carry the bacteria from the animals to infect humans.
Endemic typhus
symptoms can include rash that begins on the body trunk and spreads, high fever,
nausea, malaise, diarrhea, and vomiting; Epidemic typhus has similar but more
severe symptoms, including bleeding into th...
