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.
