BACKGROUND: Variability becomes evident not only if one compares the strains obtained from 2 different host species (host variability) but also within a single strain infesting an individual animal (individual variability). Third kind of variability is observed occasionally when strains from the same host are compared, but in geographically separated countries (geographical variability). However, morphological differences between 2 strains of Sarcoptes scabiei from human and canine scabies have not been studied well in Korea. OBJECTIVE: We compared morphologic differences between 2 strains of Sarcoptes scabiei from a Norwegian scabies patient and from a scabietic dog to assess their variabilities. METHODS: Twenty females and 10 deutonymphs of Sarcoptes scabiei from a Norwegian scabies patient and 27 Sarcoptes scabiei from a dog with canine scabies including 10 females, 10 deutonymphs and 7 protonymphs were collected and observed for this study. We measured and examined size of mites, number of squamous dorsal thorns, type of bare area, number and distribution of squamous ventrolateral thorns under the phase contrast and/or light microscopes. RESULTS: In Sarcoptes scabiei from the dog, squamous dorsal thorns and squamous ventrolateral thorns increased in number as they mature from protonymph to female. In Sarcoptes scabiei from the Norwegian scabies patient, however, squamous dorsal thorns increased in number as they mature and only 1-2 squamous ventrolateral thorns were found in a few females. In Sarcoptes scabiei from the dog, all females had type I bare area, but 8 deutonymphs (80%) had type I bare area and 4 protonymphs (57%) had type II bare area predominantly. In Sarcoptes scabiei from the Norwegian scabies patient, 9 females (90%) had type II bare area and 8 deutonymphs (80%) had type II bare area. In Sarcoptes scabiei from the dog, 8 of 10 females and 4 of 10 deutonymphs had more than three pairs of squamous ventrolateral thorns but 16 of 20 females and 10 of 20 deutonymphs from the Norwegian scabies patient did not have neither right nor left squamous ventrolateral thorns. The size of S. scabiei from the dog was bigger than the size of S. scabiei from the Norwegian scabies patient. CONCLUSION: We confirmed that individual variability, host variability, and geographical variability by observing the 2 strains of Sarcoptes scabiei from a Norwegian scabies patient and a scabietic dog. These results will be helpful for the basic references in morphological studies on scabies mites in Korea as well as in making the diagnosis of canine scabies in humans and dogs.

The infestation caused by itch mite, Sarcoptes scabiei brings about very severe itching aggravated at night, and has a very high transmissibility. The lesions are commonly found on lower abdomen, thigh, axilla, interdigital area, buttocks, and genitalia. But it is rare to find the mite on eye lid. We have experienced a 33 year-old female patient who complained of persistent itching and foreign body sense in upper eyelid, and found a mite there. Then it was removed mechaincally, and the symptoms disappeared without any particular treatment. So we report a case of eye lid infestation by S.scabiei with the review of literatures.

Norwegian, or crusted scabies, is a fulminant and highly infectious form of scabies in which a large number of Sarcoptes scabiei mites infest the epidermis. This is often seen in senile or mentally retarded patients with poor cutaneous sensation, in subjects with severe systemic disease, or immunosuppressed patients. This form of scabies differs from ordinary scabies due to the hyperkeratotic, scaly, and crusted aspect of the lesions. We report a case of Norwegian scabies in 14-year-old boy with Down's syndrome. It is the first reported case in Korea.

The clinical and biological study for Sarcoptes scabiei from 66 scabies patients was performed form Nov. 1974 to April 1975. The diagnosis of these scabies patients were confirmed by method proposed by Muller et al. The results were as follows; 1) Male to female ratio is 5. 6: 1 in total patients and predominant age group is in 16~20 in both sexes(Table 1). 2) 50% of cases had family history of similar troubles and the duration of subjective symptom complaind at their first visit was 1~2 weeks in 20 cases, 3~4 weeks in 25, 2 months in 10, and over 3 months and unknown were 12. 3) Suspected sources of infestation were, 22 cases from one of their family members, 15 at hotel, 7 at boarding house, 2 at camping, 1 at military camp, 19 were unknown. 4) Distribution of burrows was hand(79.4%), wrist(12.4%), foot(3.1%), penis(2.6%) scrotum(2.1%) and axillary area(0.5%). Number of burrows was 1~2 in 61.4%, 3~4 in 19.3%, 5~6 in 5.3%, 7~8 in 1.8%, 9~10 in 5.3% and 10 in 7. 6%. 5) 44 patients (66.7%) were confirmed by finding of female mite and among them 50% had 1 female mite, 36.7% had 2, 6.8% had 3, 2.3% had 4 and 4.5% had 6. 6) 69 among total 79 female mites detected were found at burrow, 6 from papule and 4 from vesicle. Total 7 male mites were found from patients and 4 from papules and 2 from veside and 1 from pustule(Table 5) 7) From total 194 burrows examined 69 female mites (36.1%) were found and non of male mite were found. 8) Mean size of female mite(length*breadth) was 359.3u*266.5u, male mite 21.1u*160.9u, larva 131.8ux94.2u, egg with developing larva 167.3*93.6u, egg with developed larva 159.7u * 92.3u and scybala 18.7u x 12.3u. Sizes of egg with developing larva and egg with developed larva had no significant difference, statistically.

Crusted (Norwegian) scabies is a clinical variant of human infestation with Sarcoptes scabiei, and is characterized by extensive, heavily crusted skin lesions. It usually affects immunocompromised patients. The diagnosis is commonly missed, and can lead to mismanagement. Here we report a case of crusted scabies misdiagnosed as a cutaneous side reaction due to allopurinol in a 48 year old male patient with acquired perforating dermatosis who had been treated with allopurinol for about 20 weeks. The lesion showed pruritic, excessive hyperkeratotic scaly crusts and fissures on the hands, and on pelvic, genital and inguinal areas. His skin lesions disappeared after treatment with 10% crotamiton cream for 2 weeks.

Norwegian scabies is a rare clinical variant of human infestation with Sarcoptes scabiei, distinguished from the common form of scabies by the presence of remarkable hyperkeratotic scaly crusted skin lesions. It is often seen in the physically or mentally handicapped, immunocompromised, and institutionalized persons. We report a case of Norwegian scabies occuring in a 71-year-old man with pulmonary tuberculosis. He had been treated with systemic and topical corticosteroids for extensive generalized pruritus since about 8 months before.

OBJECTIVES: To investigate an outbreak of scabies that occurred in geriatricfacilities located in Kyounggi-province, Korea, between September 2004 and September 2005. METHODS: We carried out an epidemiologic investigation on the scabies outbreak. All workers except two were interviewed and the charts of the patients were reviewed. RESULTS: Among workers, the attack rate was 58.6% (17/29). The rate was 86.0%(37/43) in patients. Secondary cases also occurred among the family members of workers, with a secondary attack rate of 15.8%. The 95% confidence interval was 6%~31.3%. The transmission of scabies began from one index case who had scabies and moved from another facility. She was hospitalized on the 4th floor of this facilitywhere dependent patients resided. After the activities (picnic and yard sale) in May 2005, and the ward rotation of care givers between the 3rd and 4th floor in July 2005, the incidence of scabies increased. The last cases occurred in Sep. 2005. CONCLUSIONS: This outbreak investigation has importance because it is the first report of ascabies outbreak in geriatric long-term care facilities in Korea. Recently, the reports on a scabies epidemic are increasing with the augmentation of geriatric long-term care facilities. It is important to educate and inform workers and staff in long-term care facilities about scabies and other contagious skin diseases. More facilities for senility and dementia will be opened and we need to lookinto contagious diseases in long-term care facilities.
