Hochu-ekki-to is a traditional herbal (Kampo) medicine that has been shown to be effective for patients with Kikyo (delicate, easily fatigable, or hypersensitive) constitution. Previous case reports have suggested that this herbal drug was effective for a certain subgroup of patients with atopic dermatitis (AD). We aimed to evaluate the efficacy and safety of Hochu-ekki-to in the long-term management of Kikyo patients with AD. In this multicenter, double blind, randomized, placebo-controlled study, 91 Kikyo patients with AD were enrolled. Kikyo condition was evaluated by a questionnaire scoring system. All patients continued their ordinary treatments (topical steroids, topical tacrolimus, emollients or oral antihistamines) before and after their protocol entry. Hochu-ekki-to or placebo was orally administered twice daily for 24 weeks. The skin severity scores, total equivalent amount (TEA) of topical agents used for AD treatment, prominent efficacy (cases with skin severity score = 0 at the end of the study) rate and aggravated rate (more than 50% increase of TEA of topical agents from the beginning of the study) were monitored and evaluated. Seventy-seven out of 91 enrolled patients completed the 24-week treatment course (Hochu-ekki-to: n = 37, placebo: n = 40). The TEA of topical agents (steroids and/or tacrolimus) was significantly (P < 0.05) lower in the Hochu-ekki-to group than in the placebo group, although the overall skin severity scores were not statistically different. The prominent efficacy rate was 19% (7 of 37) in the Hochu-ekki-to group and 5% (2 of 40) in the placebo group (P = 0.06). The aggravated rate was significantly (P < 0.05) lower in the Hochu-ekki-to group (3%; 1 of 37) than in the placebo group (18%; 7 of 39). Only mild adverse events such as nausea and diarrhea were noted in both groups without statistical difference. This placebo-controlled study demonstrates that Hochu-ekki-to is a useful adjunct to conventional treatments for AD patients with Kikyo constitution. Use of Hochu-ekki-to significantly reduces the dose of topical steroids and/or tacrolimus used for AD treatment without aggravating AD.

Since July 1973, the authors began developing a mass screening system using a VMA (vanilmandelic acid) spot test on 6‐to‐7 month‐old infants for early detection of neuroblastoma in Kyoto city, Japan. Using this method, six infants with this tumor were discovered; five of the six infants were cured, and one is under treatment. These patients showed a favorable prognosis on early diagnosis. in this article, 57 neuroblastoma patients from the Department of Pediatrics, Kyoto Prefectural University of Medicine, treated during the last 20 years, from July 1962 to June 1982, are evaluated. Since the mass screening program has run smoothly since July 1974, clinical findings are compared between 35 neuroblastoma cases before mass screening from the 12‐year period from July 1962 to June 1974 and 22 cases after mass screening, during the 8‐year period from July 1974 to June 1982. Before mass screening, only 20% (7/35) of the patients were discovered with neuroblastoma younger than 12 months of age and 68.6% were older than 2 years of age. After mass screening, 54.6% (12/22) of the patients were younger than 12 months of age and only 31.8% (7/22) were older than 2 years of age. Before mass screening, 17.1% (6/35) survived with five of the six surviving patients being younger than 12 months of age at the time of diagnosis; 72.7% (16/22) of the patients detected after mass screening are living now. Eleven of the 16 patients have already been cured, and the remaining 5 patients are presently undergoing treatment. A marked improvement of their prognoses is dependent on the early detection of this tumor by mass screening. To date, using the VMA spot test for early detection in infancy is convenient and effective for improvement of its prognosis.
