Clinical Study of Scabies and Itch Mite / 대한피부과학회지

ABSTRACT

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.
