Sarcoptes scabiei var. canis was successfully transferred from the dog to New Zealand White Rabbits, Oryctologus cuniculus. Natural and experimental transfers were accomplished between rabbits. The dog strain transferred to rabbits showed no morphologic changes and was readily transferred back to dogs. Experimental transfer of var. canis to guinea pigs and(More)
Sarcoptes scabiei var. canis served as a suitable model for the study of S. scabiei var. hominis survival. S. scabiei var. canis and var. hominis mites were found to survive off the host for 24 to 36 hours at room conditions (21 degrees C and 40% to 80% relative humidity [RH]), and the canine variety survived 19 days at 10 degrees C and 97% RH. Female mites(More)
Serum from seven patients with ordinary scabies and six with crusted scabies were screened by immunoblotting for IgE- and IgG-specific proteins in an extract of the mite, Sarcoptes scabiei variety canis. Sera from atopic individuals without sensitivity to house dust mites were used as controls. Serum from all of the patients with crusted scabies showed(More)
We report here a case study in which behavior therapy techniques were used to treat the persistent and severe scratching of a patient with long-standing exfoliative dermatitis. A multiple-baseline clinical design across different body areas was used to evaluate the behavioral treatment program. This program consisted of (1) training the patient to monitor(More)
This study determined the prevalence of Sarcoptes scabiei in the home environment of 37 confirmed cases of scabies and in five nursing homes with scabietic patients. Dust samples from 44% of infested patients' homes contained scabies mites. Live mites at the time the dust samples were analyzed were present in 64% of these homes. Live mites were recovered(More)
Cutaneous granulomatous vasculitis manifesting as a postherpetic reaction pattern is uncommon hand has previously been reported as a delayed complication of varicella-zoster virus infection. We describe three patients who had persistent, painful, postherpetic papules in a zosteriform distribution that histologically demonstrated a small vessel granulomatous(More)
Sarcoptes scabiei mites perceive specific host stimuli and are attracted to the host. Mites dislodged from the host respond to both host odor and a thermal stimulus and seek its source. The response to thermal and host odor stimuli are independent. Mites in close proximity to the body respond to both stimuli and show no preference for either. At greater(More)
Familial multiple glomus tumors are rare. A family is reported here with the disease documented in three generations. While this type of glomus tumor is not classically associated with pain, all members of this family who exhibited multiple glomangioma were symptomatic. Treatment with both the argon laser and carbon dioxide laser was successful in relieving(More)
