Multiple minute digitate hyperkeratosis: 10 years from Caccetta's algorithm. A case report and narrative review

To date, the clinical appearance and histological features of multiple minute digitate hyperkeratosis have been well characterized. However, there is no consensus on its treatment. After a comprehensive search of the databases MEDLINE, EMBASE, Web of Science, and the Cochrane Library and Database of Systematic Reviews, we have summarized the available clinical evidence regarding the therapeutic approaches already reported for this entity since its first description in 1967. Additional publications were identified within the references of retrieved papers. Sixty-five articles have been revised, resulting in a total of 73 compatible cases. The histopathological features and different classifications used through history have also been considered, updating and completing the available knowledge. Ultimately, we propose topical treatment with 5 % 5-fluorouracil formulated with 10 % salicylic acid as a potential treatment that has been used successfully in a 51-year-old woman at our facility. Further research in form of prospective or comparative studies is encouraged for a better conceptualization of the therapeutics of this disease.

Multiple Minute Digitate Hyperkeratosis: 10 Jahre nach Caccettas Algorithmus. Fallbericht und narrative Übersicht

Das klinische Erscheinungsbild und die histologischen Merkmale der Multiple Minute Digitate Hyperkeratosis sind bereits gut charakterisiert. Es besteht jedoch kein Konsens über die Behandlung dieser Erkrankung. Nach einer umfassenden Recherche in den Datenbanken MEDLINE, EMBASE, Web of Science und der Cochrane Library and Database of Systematic Reviews haben wir die vorliegenden klinischen Daten zu den therapeutischen Ansätzen zusammengefasst, die für diese Entität seit ihrer Erstbeschreibung im Jahr 1967 publiziert wurden. Zusätzliche Veröffentlichungen wurden in den Referenzen der gefundenen Artikel identifiziert. Fünfundsechzig Artikel wurden durchgesehen, sodass sich insgesamt 73 kompatible Fälle ergaben. Die histopathologischen Merkmale und die verschiedenen Klassifizierungen, die im Laufe der Zeit verwendet wurden, wurden ebenfalls berücksichtigt. Letztendlich schlagen wir die topische Behandlung mit 5% 5‐Fluorouracil in Kombination mit 10% Salicylsäure als eine mögliche Behandlung vor, die bei einer 51‐jährigen Frau in unserer Einrichtung erfolgreich angewendet wurde. Weitere Forschung in Form von prospektiven oder vergleichenden Studien werden empfohlen, um ein besseres Konzept für die Therapie dieser Krankheit zu entwickeln.

A Pilot Study on the Feasibility of Developing and Implementing a Mobile App for the Acquisition of Clinical Knowledge and Competencies by Medical Students Transitioning from Preclinical to Clinical Years

Due to the COVID-19 pandemic and the consequent restrictions, universities have had to adapt their curricula substantially to new schemes in which remote learning is of the essence. In this study, we assess the feasibility of developing a mobile app supplementary to the distant teaching paradigm for the “Cardiology” module of the “General Pathology” subject in undergraduate Medical Education, and we evaluate its impact and acceptability. A cohort of volunteer second-year medical students (n = 44) had access to the app, and their opinions on its utility (1−10) were collected. Additionally, the students were invited to refer their expected satisfaction (1−10) with a blended learning methodology overlapping this new tool with the traditional resources. The average expected satisfaction had been compared to the average satisfaction obtained by just the traditional methodology in other modules from the same subject. Through a qualitative approach, we defined the strengths and weaknesses of the tool. Seventy-seven percent of the participants rated at 8/10 or more the potential learning value of the application and, if used as a supplement to traditional teaching, it would also statistically improve the satisfaction of students (6.52 vs. 8.70, p < 0.001). Similarly, the qualitative data corroborated the benefits of such innovation. Multidisciplinary collaborations are encouraged to develop teaching innovations, although further research should aim to better define the effectiveness of learning with these resources.
