Differential diagnosis between urticaria and cheiropomphylyx
was often difficult too. Out of 91 scabies cases seen at Park House
Centre, five were first diagnosed as cheiropomphylyx and four as
urticaria. In the same period 56 cases of urticaria, and 17 of
cheiropomphylyx attended the clinic. Ten cases, first suspected
of being scabies, were in the end considered as merely urticaria.
Treatment.
Various forms of treatment were used during 1942. The
experience of 1941 had shown that beta naphthol ointment was
not very efficacious. Of 14 cases of scabies treated with it in 1941,
seven showed no improvement and three had recurrences some
weeks after apparently clearing up.
Although sulphonil was subsequently reported in the medical
press to have no sarcopticidal properties, 38 cases were treated with
it when it first came out as a remedy and in only two cases did
scabies recur. The remaining 53 cases were treated with benzyl
benzoate emulsion, 18 carrying out the treatment at home, and
35 at the Scabies Clinic.
