Scabies is an itchy, highly contagious skin disease and is caused by an infestation by the itch mite Sarcoptes scabiei. The mites that infest humans are female; the males are about half this size of female mites. Scabies mites can be seen with a magnifying glass or microscope. The scabies mites crawl but are unable to fly or jump. They are immobile at temperatures below 20 C, although they may survive for prolonged periods at these temperatures.

Scabies is an ectoparasitic skin infection with the mite Sarcoptes scabiei var. humanus and is caused by the female mite.

It is spread by skin to skin, via both sexual and nonsexual contact, and in some cases as fomites, which means that scabies is mostly transmitted by direct contact with the infected person or things of his/her personal use.

The most commonly affected areas are the interdigital web spaces, axillae, genital area, buttocks, and breasts. it usually takes four to six weeks (incubation period) for the symptoms to start showing.

In cases where scabies have occurred earlier, it takes one to four days for the symptoms to appear, after exposure.

Norwegian scabies (first described in Norway), or crusted scabies, is a severe form of scabies.

Crusted scabies almost always affects people with a compromised immune system and is observed most frequently in the elderly, those who are mentally or physically disabled, and patients with AIDS, lymphoma, or other health conditions that decrease the effectiveness of the immune response. Due to the poor function of the immune system, an individual may become infested with hundreds of thousands of mites.

The lesions of this distinctive form of scabies are extensive and may spread all over the body. The elbows, knees, palms, scalp, and soles of the feet are most commonly the original sites of involvement, and the scaly areas eventually take on a wart-like appearance. The fingernails can be thickened and discolored. Interestingly, itching may be minimal or absent in this form of scabies.

A particular danger of crusted scabies is that these lesions often predispose to the development of secondary infections, as with Staphylococcus or Streptococcus bacteria, including impetigo, a common skin infection in children.

Pets are infected by different types of mites than those that infect humans. Animals are not a source of the spread of human scabies. Scabies on dogs is called mange and is sometimes referred to as sarcoptic mange. When canine or feline mites land on human skin, they fail to thrive and produce only a mild itch that goes away on its own.

Symptomes

The main symptoms of scabies are severe itching accompanied by superficial burrows and skin rashes, itching may be more severe at night. The superficial burrows and skin rashes appear mostly on the feet, wrist, fingers (especially web of fingers), elbow, back, and hips.

The severe itchiness compels the person to scratch constantly which may lead to the breakdown of the skin, leaving it open to further infection.

The female mite burrows under the skin and produces eggs and scybala. Acarus scabiei has four pairs of legs.

Acarus scabiei undergoes its life cycle on the skin surface. The male mite fertilizes the female and dies.

The adult female, after impregnation, burrows into the skin at the rate of 1 to 5 mm per day and forms and a tunnel in the horny layer (stratum corneum).

Two days after fertilization, it starts laying two to three eggs per day along her course in the burrow.

Acarus lays a total of 10 to 25 eggs during her life span of 30 days and then dies at the end of the burrow. The egg hatches in 3 to 4 days producing a larva that moves to the skin surface.

It then moults through various stages of octopod nymph into an adult mite in 10 to 14 days.

A type 4 delayed hypersensitivity reaction occurs after approximately 1 month in unsensitized patients or within hours in sensitized patients. This leads to the severe itching that is characteristic of scabies infection.

GENERAL MANAGEMENT of SCABIES

• Maintain personal hygiene.
• Change clothes, bed sheets/linens daily.
• Regular/daily bath.
• Clothes & bed linens to be washed in hot water, dried in sun & ironed.
• Thorough scrubbing with soap & water.

Curing scabies is rather easy with the administration of prescription scabicide drugs. There are no approved over-the-counter preparations that have been proven to be effective in eliminating scabies, and home remedies are not effective. Since scabies is a parasitic infestation, antibiotics used to treat bacterial infections are not effective.

The following steps should be included in the medical treatment of scabies:

1. Apply a mite-killer like permethrin. These creams are applied from the neck down, left on overnight, then washed off. This application is usually repeated in seven days. Permethrin is approved for use in people 2 months of age and older and is considered to be the safest and most effective treatment for scabies.
2. An alternative treatment is 1 ounce of a 1% lotion or 30 grams of cream of lindane, applied from the neck down and washed off after approximately eight hours. Since lindane can cause seizures when it is absorbed through the skin, it should not be used if the skin is significantly irritated or wet, such as with extensive skin disease, rash, or after a bath. As an additional precaution, lindane should not be used during pregnancy or in nursing women, the elderly, people with skin sores at the site of the application, children younger than 2 years of age, or people who weigh less than 110 pounds. Lindane is not a first-line treatment and is only recommended if patients cannot tolerate other therapies or if other therapies have not been effective. Resistance to this medication has also been frequently reported.

Over-the-counter and prescription medications to treat scabies include:

• Ivermectin, an oral medication, is an antiparasitic medication that has also been shown to be an effective scabicide, although it is not FDA-approved for this use. The CDC recommends taking this drug at a dosage of 200 micrograms per kilogram body weight as a single dose, followed by a repeat dose two weeks later. Although taking a drug by mouth is more convenient than the application of the cream, oral ivermectin has a greater risk of toxic side effects than permethrin and is not superior to permethrin in eradicating scabies. It is typically used only when topical medications have failed or when the patient cannot tolerate them.
• Crotamiton lotion 10% and cream 10% is another drug that has been approved for the treatment of scabies in adults, but it is not approved for use in children. However, treatment failures have been documented with the use of crotamiton.
• Sulfur in petrolatum (Sulfo-Lac, Sulfo-Lo) applied as a cream or ointment is one of the earliest known treatments for scabies (sulfur is safe for use during pregnancy and in infants).

Homeopathic treatment for Scabies

Homeopathic medicines for scabies stimulate the disease-fighting mechanism (immune system) of the body to fight scabies and secure organism in future for disease like this one (treated).
