Epidemiological analysis of the patients with psoriasis in Asian countries and region using the same clinical case cards between 2020 and 2022.

Although many epidemiological surveys for patients with psoriasis have been reported based on individual countries or facilities, there has been no study encompassing the major countries or the region in Asia. The Asian Society for Psoriasis (ASP) has been conducting an epidemiological study across various Asian countries and regions to elucidate the and compare the epidemiology of psoriasis. A total of 1948 cases were analyzed, with 938 cases from Japan, 530 cases from China, 325 cases from Korea, 141 cases from Chinese Taipei, and 14 cases from Thailand, all of which were enrolled between 2020 and 2022. In the Asian region total, the male-female ratio was 1.87:1 and the peak age at disease onset was 20-29 years. The proportion of psoriasis vulgaris (PsV), psoriatic arthritis (PsA), and pustular psoriasis (PP) was 80.1%, 17.7%, and 2.2%, respectively, and PsA was more commonly associated with nail symptoms than psoriasis vulgaris (PsV). Of the patients, 13% had a familial history of psoriasis and the most frequently affected family member was the father. Regarding treatment, 78.3% of the patients received topical medications, 9.0% underwent phototherapy, 34.0% received oral medications, and 36.1% were treated with biological agents. This study provided valuable information on the epidemiology and treatment of psoriasis using the registry data collected with the common reporting form in the same period in major Asian countries and regions. Male predominance is a distinctive feature of psoriasis in Asia. This epidemiological data registry in the ASP will continue afterwards.

Oral Ulcers as an Initial Presentation of Juvenile Pemphigus: A Case Report.

Pemphigus vulgaris (PV) is an autoimmune disease in which the autoantibody, immunoglobulin G, is directed against the keratinocytes in the epidermis. The classic presentations of PV are flaccid vesicles or bullae over the oral mucosa, trunk, groin, and extremities. The age of onset is usually between 40 and 60 years, and cases of PV in children or adolescent patients are rare. Here, we present a 17-year-old boy who had painful oral ulcers for 3 months initially and bullae spreading to the whole body in the following days. Paraneoplastic pemphigus was another differential diagnosis due to the atypical appearance of the skin lesion. However, PV was confirmed by hematoxylin and eosin staining and immunofluorescence examination of the skin biopsy specimens. The patient had a good response to corticosteroid treatment and the immunosuppressive agent, rituximab.

What can U.S. dermatology learn from health care systems abroad? An observation of Taiwan's system of clinical efficiency as a possible model for increased patient access to care and affordability.

BACKGROUND: Difficulty in patient access to care and affordability are major problems faced by our dermatology specialty in the United States. However, Taiwan provides adequate and affordable dermatologic care for all of its citizens. Herein we describe our first-hand observations and findings of the outpatient dermatology experience in Taipei, and contrast it to the experience in the United States. OBSERVATION: In Taipei, Taiwan, we observed patient management, electronic documentation, and billing during outpatient dermatology visits in five settings: one academic hospital outpatient dermatology department, one academic hospital Information Technology department, and three private dermatologists' offices. Through our observations, we found that the dermatology specialty in Taiwan is able to overcome challenges with access to care and affordability through three key system features: (1) short yet frequent patient visits (2) close proximity of ancillary staff, and (3) an integrated and paperless electronic medical record and billing system. CONCLUSIONS: The Taiwan system is attained with some sacrifice, such as shorter time spent with patients and less personalized care. However, because this system can meet the basic dermatological needs of the entire population, possibly better than our current system, it behooves us to study the Taiwan system with respect and care.
