Objective: The present study aimed to assess the course of patients with atopic dermatitis (AD) receiving dupilumab treatment., Methods: The present, retrospective survey enrolled 201 patients with AD between May 2018 and May 2022 to examine their previous treatment, skin score, percentage of self-injections, EASI improvement rate, treatment continuation rate, number of treatment interruptions, and reasons for the interruptions., Results: The average EASI severity score was 39.5±18.1, and the self-injection rate was 83%. The percentage of improvement in patients with an EASI-75 was 63% at week 16 and EASI 100 was 15.9% at week 60. At week 16 of treatment, the patients were divided by their improvement rate into an EASI-75, < 50 group. The EASI-75 group maintained their improvement rate until week 60. In the EASI< 50% group achieved 73.4% at week 60. The treatment continuation rate was 82.6%, and 35 patients discontinued the treatment, in most cases shortly after commencement., Conclusion: Dupilumab has revolutionized AD treatment, markedly improving skin symptoms. The present study was the first in Japan to demonstrate a treatment continuation rate of 82.6% at week 60 at a single center. Clear guidelines on long-term, complete maintenance treatment with dupilumab await formulation.

Background: Connecting individuals in need of psychiatric treatment with adequate medical services has been a major strategy for suicide prevention in Japan. By investigating serious suicide attempters admitted to our Critical Care Medical Center (CCM), we aimed to examine longitudinal changes in the psychiatric treatment status of high-risk suicidal individuals, and to explore the association between any improvement in psychiatric treatment status and suicide decline., Methods: Subjects from two periods, 2006-2011 and 2012-2017, were enrolled. We collected the data of 32,252 suicides in Tokyo from police reports and the data of 942 suicide attempters admitted to CCM from medical records. Data were annually collected by both age and gender for the number of suicide completers, the number of suicide attempters, and the psychiatric treatment rates, respectively. ANOVA and t-test were used to examine whether there were differences in the number of suicides and attempers between the two periods. The difference in psychiatric treatment rate between the two periods was examined by chi-square test. Additionally, we used Pearson's correlation coefficient to analyze any correlation between annual treatment rate and the number of suicide completers in subgroups with altered psychiatric treatment rates., Results: The number of suicide attempters in the 20-39-year age group of decreased together with the number of suicides. Psychiatric treatment rates of male attempters aged 20-59 years improved significantly from 48.7 to 70.6% and this improvement correlated with a decrease in suicides. However, psychiatric treatment rates in the elderly, which have the highest number of suicides in both genders, did not improve and remain low., Conclusions: The number of suicide attempters, as well as that of suicides, decreased in Tokyo. Improvement of psychiatric treatment status in high-risk suicidal male adults may have contributed to the reduction of suicides in Tokyo. However, the continuing low rate of psychiatric treatment in the elderly is a pressing issue for future suicide prevention., (© 2022. The Author(s).)

Objective: There are few epidemiological reports of anaphylaxis since childhood. We herein examined cases of anaphylaxis diagnosed in our department., Methods: One hundred-thirty-two patients who were examined at the Dermatology Department of Tokyo Medical University Hospital between January 2011 and March 2017 and were prescribed epinephrine autoinjector (EpiPen ® ) for treatment were enrolled. The referral institution if any, severity of anaphylaxis, diagnostic method, causative antigen, and recurrence rate was examined., Results: The referral rate was 54% while 46% of patients requested examination of their own accord. Anaphylaxis severity was mild to moderate in 75% of cases. Food allergy accounted for 71% of the symptoms, with wheat as the most common causative antigen, followed by Anisakis allergy. After diagnosis only 37% of patients continued periodic consultations, and 16 patients recurred anaphylaxis of the diagnosis., Conclusion: Wheat and WDEIA were the most frequent causes of anaphylaxis diagnosed in our department. We also found that as many as 15% of patients had Anisakis allergy, suggesting that it may be an important item in antigen testing.

The main World Health Organization (WHO) activities of the Tokyo Center are as follows: (1) It performed the research project entitled 'A Bio-Psycho-Social Study on Children with Emotional and Behavioral Problems' in cooperation with the Beijing and Seoul Centers from 1985 to 1987. These results suggested that the deviant behavior of children in the general population had no biological background, but presumably stemmed from psychosocial disadvantages. (2) It has participated in a field trial for the proposed draft for chapter V of the ICD-10 as the Field Trial Coordinating Center in Japan since 1986 and the first Japanese edition of the ICD-10 Classification of Mental and Behavioral Disorders: Clinical Descriptions and Diagnostic Guidelines were published in 1993. (3) It proposed the collaborative project exploratory eye movements in patients with schizophrenia in 1989 and has promoted the project with the cooperation of six centers that included Beijing, Casablanca, Montreal, Munich, Prague and Sapporo. The findings of the present project indicated that exploratory eye movements may be specific to schizophrenia and can be practically used to discriminate schizophrenia without significantly depending on language.
