Head lice and the human hair The head louse (Pediculus humanus capitis) is an insect parasite, spending its entire life on human hair and feeding exclusively on blood, 4-5 times daily. Man is the only known host of this parasite.
Scalp pediculosis
Topical pediculicides remain the main treatment. Permethrin shampoo 1% should be left on the scalp for 10 min and then rinsed. Piperonyl butoxide 15% may also be used as shampoo. Permethrin 5% may also be used, applied to the scalp at night, and removed the next day.
Lice and other crawling parasites appear as tiny, slow moving crawlers on the hair and scalp. The result of infestation is a papular rash with extreme itching.
Demodex folliculorum and Demodex brevis are two species of tiny parasitic mites that live in the hair follicles and sebaceous glands of human skin, respectively.
The most common symptoms of scabies, itching and a skin rash, are caused by sensitization (a type of “allergic” reaction) to the proteins and feces of the parasite. Severe itching (pruritus), especially at night, is the earliest and most common symptom of scabies.
The head louse (Pediculus humanus capitis) is an insect parasite, spending its entire life on human hair and feeding exclusively on blood, 4-5 times daily.
There are two medications that can be used to treat the infection and manage the symptoms. The treatment of choice is diethylcarbamazine (DEC), which kills the microfilariae and adult worms. Albendazole is sometimes used in patients who are not cured with multiple DEC treatments.
Seizures and headaches are the most common symptoms. However, confusion, lack of attention to people and surroundings, difficulty with balance, excess fluid around the brain (called hydrocephalus) may also occur.
Eat more raw garlic, pumpkin seeds, pomegranates, beets, and carrots, all of which have been used traditionally to kill parasites. In one study, researchers found that a mixture of honey and papaya seeds cleared stools of parasites in 23 out of 30 subjects. Drink a lot of water to help flush out your system.
Horsehair worms are slender (1/25 to 1/8 inch wide), very long (4 to 24 inches), and yellowish-tan to brownish-black in color. They often squirm and twist, knotting themselves into a loose, ball-like shape, resembling the so called "gordian knot," in freshwater pools.
What can cause sores or scabs on the scalp? Sores or scabs on the scalp are often harmless and clear up on their own. However, they can sometimes be a sign of a condition that may require treatment, such as psoriasis, contact dermatitis, or head lice.
Cutaneous larva migrans is a pruritic dermatitis due to the inoculation of helminths larvae in the skin, and it often occurs in children in tropical and subtropical areas.
Several insect parasites can produce oozing skin eruptions and hair loss. Prominent among these is the sarcoptic mange mite, which has a worldwide distribution. Sarcoptes scabiei mites parasitize many different mammals.
Some parasitic infections disappear on their own, especially if your immune system is healthy and you eat a balanced diet. For parasites that don't go away on their own, your doctor will generally prescribe oral medication. This treatment is generally effective and proven to work.
Fungi called dermatophytes cause ringworm of the scalp. Fungi are organisms that thrive on dead tissue, such as fingernails, hair, and the outer layers of your skin. Dermatophytes prefer warmth and moisture, so they thrive on sweaty skin. Overcrowding and poor hygiene increase the spread of ringworm.

The finding that liquid hand soap efficiently destroys all three parasites suggests that soap solutions can be used as first aid measure to clean skin areas accidentally contaminated with the pathogens.
A stool ova and parasite, or O&P, test is a simple way of diagnosing parasite infections. This test determines whether parasites and their eggs are present in your stool. The stool O&P test is a common way to find out if you have parasites in your digestive tract.
Lagochilascariasis is mostly a chronic human disease that can persist for several years, in which the parasite burrows into the subcutaneous tissues of the neck, paranasal sinuses, and mastoid.
Almost all parasitoses involving the human brain can be associated with seizures and epilepsy, either by a diffuse encephalitis or encephalopathy, or by intracerebral location of the parasite [5].
Ingestion of contaminated water causes the larvae to migrate from the intestines via the abdominal cavity to the tissue under the skin. The larvae mature and release a toxic substance that makes the overlying skin ulcerate. After treatment, symptoms disappear and the worms can be safely removed from the skin.
Epidermal parasitic skin diseases (EPSD) are a heterogeneous category of infectious diseases in which parasite–host interactions are confined to the upper layer of the skin. The six major EPSD are scabies, pediculosis (capitis, corporis and pubis), tungiasis and hookworm-related cutaneous larva migrans.
Parasites on the skin are usually small insects or worms that burrow into the skin to live there or lay their eggs.
