The doctor may also test tissue fluid or smears from the child's lesions to rule out skin parasites or infections that mimic atopic dermatitis, such as bacterial infections, scabies, or herpesvirus infections.
Although the mites can only live away from human skin for about three days, sharing clothing or bedclothes can pass scabies among family members or close contacts.
In patients with weak immune systems, the biggest danger is that the areas of skin involved with scabies will become secondarily infected with bacteria.
A doctor may need to distinguish between body lice and scabies (a disease caused by skin mites) and between pubic lice and eczema (a skin condition).
In May 2002, the Centers for Disease Control (CDC) included scabies in its updated guidelines for the treatment of sexually transmitted diseases.
When a member of a household is diagnosed with scabies, all that person's recently worn clothing and bedding should be washed in very hot water.
Preparations containing lindane are no longer recommended for treating scabies because of the potential for damage to the nervous system.
In scabies (itch) it is the best remedy, killing the male parasite, which remains on the surface of the skin.
(It is fair to say that these views were published in one of his later works.) In treatment of disease Hahnemann rejected entirely the notion of a vis medicatrix naturae, and was guided by his well-known principle 1 The itch (scabies) is really an affection produced by the presence in the skin of a species of mite (Acarus scabiei), and when this is destroyed or removed the disease is at an end.
Similar spots are produced on potatoes in America by the fungus Oospora scabies, and in both cases, if affected "seed" potatoes are steeped in a solution of 2 pint formalin in 15 gallons of water for two hours before planting, the attack on the resulting crop is materially lessened.
