The patch test is the most reliable method for diagnosing a metal allergy. However, interpretation of patch test results depends on the experience of the investigator and on the conditions of the individual patient. In the case of patch tests for metal salts, irritant reactions such as pustular or follicular reactions are quite common. Therefore, one must be careful not to interpret irritant reactions as allergic responses, and objective standards to evaluate erythema in patch tests need to be established.In the present study, we attempted to objectively evaluate patch test results for metal salts using an erythema index meter. We used the Erythema Index Difference (EID) (patch test site erythema index (EI) minus the mean EI of healthy skin outside the patch test area and at the unit tape site) rather than the EI itself in order to eliminate the effects of the patch test unit and individual differences. We measured the EID over time in patients with suspected metal allergies to various metals. Significant differences in EID were observed among ++ assessments, + assessments and irritant reactions based on International Contact Dermatitis Research Group (ICDRG) standards. In considering changes in EID over time, allergic and irritant reactions can be discriminated with high sensitivity (73.3%) and specificity (91.2%).These results suggest that the measurement of erythema over time with an erythema index meter is useful for the objective assessment of metal patch test reactions.

Chi-no-michi-sho involves neuropsychiatric and physical symptoms that appear with hormonal changes, such as those during pregnancy and menopause. Until now, there were many case reports, which were within 2 years from the start of treatment. We present a case of chi-no-michi-sho that was successfully treated with Kampo formulations for 7 years. A 43-­year-­old woman had complaints of candida eczema in the vulva, palpi­tations, and headache. Tokishakuyakusan and shakanzoto were then administered for kekkyo (blood defi­ciency), oketsu (blood stasis), and suidoku (fluid retention), and a topical antifungal agent was administered for candida eczema. The headache and palpitations were reduced. Subsequently, tokishigyakukagoshuyuto and keishibukuryogan were administered because of skin rash and deterioration of sensitivity to cold. However, various symptoms, such as weight loss amenorrhea due to self-­determination, eczema, feeling heavy in the head, and edema, remained. We prescribed tokishakuyakusan again in addition to Western medical treatment. Her menstruation then resumed ; her eczema, palpitations, and headache also improved. However, she developed hyperthyroidism. While paying attention to organic diseases such as thyroid dysfunction, prescription of tokishakuyakusan may be effective when chi-no-michi-sho is long­-lasting and there are blood deficiency and stasis with fluid retention.

Prostate cancer is one of the most common diseases in men worldwide. Surgery, radiation therapy, and hormonal therapy are effective treatments for early-stage prostate cancer. However, the development of castration-resistant prostate cancer has increased the mortality rate of prostate cancer. To develop novel drugs for castration-resistant prostate cancer, the molecular mechanisms of prostate cancer progression must be elucidated. Among the signaling pathways regulating prostate cancer development, recent studies have revealed the importance of noncanonical wingless-type MMTV integration site family (WNT) signaling pathways, mainly that involving WNT5A, in prostate cancer progression and metastasis; however, its role remains controversial. Moreover, chromatin remodelers such as the switch/sucrose nonfermentable (SWI/SNF) complex and chromodomain helicase DNA-binding proteins 1 also play important roles in prostate cancer progression through genome-wide gene expression changes. Here, we review the roles of noncanonical WNT signaling pathways, chromatin remodelers, and epigenetic enzymes in the development and progression of prostate cancer.
