HOW TO GET RID OF HAIR LICE.

A sesame seed-size parasite that feeds on human blood, the head louse (Pediculus humanus capitis) is a nuisance known around the world. These tiny insects infest human hair and can also sometimes be found in the eyebrows and eyelashes.

Signs & symptoms

Some people with lice never realize they're infested. However, there are several telltale signs that the bugs are present on the scalp, according to the Mayo Clinic. These include:

A ticklish feeling on the scalp or neck.
An itchy scalp (the result of an allergic reaction to the bug's saliva).
Small red bumps on the scalp, neck and shoulders.
The presence of lice on the scalp.
The presence of nits (lice eggs) on shafts of hair.
Difficulty sleeping, which can lead to irritability. Some people with lice may also develop sores on their scalp. Such sores are likely the result of bacteria from the person's own body infecting an opening in the skin made by scratching, according to the CDC. Some people may scratch their scalps raw due to the itch and cause skin infections, said Margaret Khoury, a pediatric infectious disease specialist with Kaiser Permanente.

Diagnosis

The best way to confirm an active lice infestation is to find a live louse on the head, according to the American Academy of Pediatrics (AAP). Because lice move quickly and avoid light, it's best to check for them after wetting the hair, which some experts say slows the insects down.

Treatment

There are several treatment options for those with head lice, including shampoos and creams that contain pediculicides,

or insecticides that kill lice, as well as combing the hair with a louse comb that removes lice and nits.

Health risks of high heeled shoes.

It is so common to see some ladies put on high heels and be on them for hours. If you are one of them, have you sat down and asked yourself if it in anyway affects your health? I will be glad to share the possible health risks of wearing such shoes with you. Consider what a doctor who is a member of the American osteopathic association says " High heels put the foot at an angle and pull muscles and joints out of alignment, so the effects aren’t limited to the feet,” Dr. Surve explained. “It’s not unusual for people who spend lots of time in high heels to have low back, neck and shoulder pain because the shoes disrupt the natural form of the body.” Structurally, the plantar fascia in the foot is connected to the calf muscle, which in turn connects to the hamstring. The hamstrings attach to the pelvis and low back, which is why wearing high heels can make your back ache along with your feet. Also, walking on the balls of your feet will shift your center of gravi...

MOSQUITOES AND MALERIA- WHAT YOU MUST KNOW!

Malaria is caused by a one-celled parasite called a Plasmodium . Female Anopheles mosquitoes pick up the parasite from infected people when they bite to obtain blood needed to nurture their eggs. Inside the mosquito the parasites reproduce and develop. When the mosquito bites again, the parasites contained in the salivary gland are injected and pass into the blood of the person being bitten. Malaria parasites multiply rapidly in the liver and then in red blood cells of the infected person. One to two weeks after a person is infected the first symptoms of malaria appear: usually fever, headache, chills and vomiting. If not treated promptly with effective medicines, malaria can kill by infecting and destroying red blood cells and by clogging the capillaries that carry blood to the brain or other vital organs. In recent years, some human cases of malaria have also occurred with Plasmodium knowlesi – a species that causes malaria among monkeys and ...
