Description Scabies is an infection caused by the mite Sarcoptes scabiei. Infections occur when newly fertilized female mites are transferred from person-to-person through close contact. Crowded, unclean conditions and sexually promiscuity increase the risk of contracting scabies. Medical personnel are also at increased risk of infection.
Symptoms
Sever itching of the infected area
Blisters or scabbed blisters in runs or burrows on finger webs, the heel of palms, and wrist creases
Small red raised lesions on the penis shaft
Diagnosis
Scrapings of lesion are viewed under a microscope. The presence of mites, ova (eggs), or feces confirms the diagnosis.
Burrow ink test involves ink being placed on the burrow and then scraped. The mite, ova, and feces can be seen under the microscope.
Treatment
Bedding and clothing should be cleaned and set aside for 48 hours.
A one-time application of Permethrin 5% cream for 8 to 12 hours is recommended. This regimen is safe and effective.
Lindane cream is more toxic than Permethrin and may pose dangerous side effects in children due to potential neurotoxicity.
Benzyl benzoate lotion may also be applied
Corticosteroids may be used for dermatitis (skin inflammation) that are caused by scabies.
