Psoriasis dermatitis, a common phenotype of early forms of both psoriasis and atopic dermatitis in children: A prospective multicenter study.

BACKGROUND: Psoriasis (Ps) and atopic dermatitis (AD) are chronic systemic immune-mediated diseases that can coexist in an overlapping condition called psoriasis dermatitis (PD). PD patients have intermediate lesions with characteristics of both Ps and AD. PD is very rare in adults but much more frequent in children. Little is known, however, about the course of PD in the pediatric population. The aim of this study was to evaluate the percentage of PD cases in children that evolved to a definite form of Ps or AD and to identify any clinical or epidemiological variables that could predict the course of the disease. METHODS: We performed a prospective multicenter cohort study of children diagnosed with PD between January 2018 and December 2020. We collected participants' clinical and epidemiological characteristics, and pediatric dermatologists determined the percentage of participants who developed Ps or AD. RESULTS: The study included 24 children with PD, with a median age of 7.0 years. After a median follow-up period of 31 months, 83.3% of cases had evolved to a definite form of Ps or AD (44.4% to Ps and 38.9% to AD). Younger age and family history of Ps were associated with progression to AD. Participants who progressed to AD or Ps had a longer follow-up than those with an unchanged PD diagnosis. CONCLUSIONS: Given sufficient time, a large percentage of PD cases in children will evolve into Ps or AD. Long-term clinical follow-up is necessary for a correct diagnosis.

OBJECTIVE: Analyze the scientific articles published in Actas Dermo-Sifiliográficas (AD) between 1984 and 2003. The main bibliometric parameters analyzed were: number of articles, their length and type, primary subject areas, authorship of the documents, main contributing centers, departmental areas and geographic distribution of the articles. MATERIAL AND METHODS: All of the scientific articles published in the regular issues of the journal Actas Dermo-Sifiliográficas between 1984 and 2003 (two decades), corresponding to volumes 75 to 94, were reviewed manually. RESULTS: A total of 2,604 articles were published in the journal AD during the period studied, with a yearly average of 130 articles. Clinical cases or notes were the main type of document (66.2 %), followed by original articles (23.5 %) and review articles (4.7 %). The length of the documents varied from 1 to 33 pages, with an average of 4.55 pages. The subjects that were most discussed in the documents from this period were dermatopathology (15.9 %) and therapeutics (15.4 %). A total of 11,667 authorships were found, with 2,907 different authors. The average number of authors per article for the period was 4.48. 56.7 % of the authors were occasional contributors (having signed a single document), while 3.5 % were top contributors, having signed 20 or more works over this period. Seven Autonomous Communities accounted for 85.5 % of the articles. The Community of Madrid was by far the largest contributor (917 documents, 35.2 %), followed by Andalusia (422, 16.2 %), Catalonia (240, 9.2 %) and Castile-León (221, 8.5 %). The 2,604 documents in the study were from 293 different centers, which accounted for 2,977 co-authorships. Most of these co-authorships were from large hospitals or hospital complexes. The most noteworthy of these were the Madrid hospitals 12 de Octubre (281 co-authorships) and Clínico San Carlos (153), and Hospital Universitario San Cecilio in Granada (149). Dermatology was the specialty of most of the authors (90.8 % of those authors listed first). The main specialty collaborating with dermatology was pathology, taking part in 28.5 % of the articles. CONCLUSIONS: An analysis of the productivity of the journal AD over two decades gives us an idea of scientific activity in dermatology in Spain, because of the journal's quantitative and qualitative significance in the context of Spanish dermatology.

OBJECTIVE: To quantify the impact factor of the journal Actas Dermo-Sifiliográficas (AD) from 1986 to 1990 and from 1999 to 2003 and to identify the journal's citation pattern in those years. MATERIAL AND METHODS: Citations obtained by AD in the periods from 1985-1990 and 1998-2003 for articles published from 1984 to 1989 and from 1997 to 2002 were collected using Science Citation Index Expanded (SCI). RESULTS: The number of times AD was cited doubled during the second period, increasing from 38 (period from 1985-1990) to 76 (period from 1998-2003). Considering the number of citations, AD's impact factor increased from 0.016 in 1986 to 0.040 in 2003. In both periods, citations corresponding to AD articles were included in a wide range of source journals, mainly dermatological publications abroad. The most referred journals in the second period were the Dutch publication Journal of the European Academy of Dermatology and Venereology (13 citations) and the Journal of the American Academy of Dermatology (12 citations). Unlike the period from 1985 to 1990 when no Spanish journal cited AD, four Spanish publications mentioned AD in the second period: Revista clínica española (6 citations), Archivos de bronconeumología (4 citations), Medicina clínica (3 citations) and the journal Enfermedades infecciosas y microbiología clínica (1 citation). Citations mainly corresponded to articles published by Spanish authors (63.2 % in the 1985-1990 period and 81.6 % in the period from 1998 to 2003). Self-citation increased from 10.5 % (first period) to 31.6 % (second period). CONCLUSION: The impact factor of AD is low and not comparable to other publications included in the Dermatology and Venereal Diseases field from SCI. Our results confirm the low citation rate of AD by source journals in this repertory. However, the increase of this rate in recent years seems to indicate a higher Spanish presence in SCI due to an increasing number of publications corresponding to Spanish authors in international journals and the inclusion of some Spanish journals in this database.

OBJECTIVE: To quantify the number of references for each of the articles published in the regular issues of the journal Actas Dermo-Sifiliográficas (AD) between 1984 and 2003, and to calculate the average number of references for each of these years. To study the consumption of information by the authors of documents published in AD through the analysis of all of the bibliographical references listed in the articles published in 1984, 1993 and 2003. MATERIAL AND METHODS: The number of references for each of the scientific articles published in the regular issues of the journal Actas Dermo-Sifiliográficas between 1984 and 2003 was reviewed manually. For the years 1984, 1993 and 2003, the type of document, language, country of origin and age of the references were analyzed. RESULTS: The 2,604 articles published in the journal AD between 1984 and 2003 provided 56,144 references. The average number of references per article for the entire period was 21.56 +/- 21.2. The type of document with the most references was the review (67.06 +/- 59.9), followed by original works (24.76 +/- 19) and clinical cases (17.95 +/- 9.7). The primary type of document for references in the three years studied was the review article, which went from 84.8 % in 1984 to 95.4 % in 2003. References to books, on the other hand, dropped from 10.6 % in the first year to 3.3 % in the last one (p < 0.001). The United States was the country of origin of a large part of the references reflected in the three years studied (55.4 %). Following at a great distance were the United Kingdom (15.7 %) and Spain (9 %). English was the language in which most of the references were written in the three years studied, increasing from 72.9 % in 1984 to 87.5 % in 2003. Spanish was the second most used language in the references (9.1 %); contrary to what was expected, its use decreased over the three years. The main journals referenced by the authors published in AD were the American publications Archives of Dermatology (12.3 %) and Journal of the American Academy of Dermatology (10.3 %). References to AD itself accounted for 4 % of the total; it was the fourth most referenced journal after the British Journal of Dermatology (7.4 %). CONCLUSIONS: Spanish dermatologists primarily use English-language publications for their research. They mostly obtain current information from periodicals, with a significant percentage of the information being found in a small group of journals, which are the ones with the greatest international impact for our field of specialization.
