The Showcases of Dental History - A Time Machine in Miniature at the University of Puerto Rico: Part I.

The evolution of 20-year-old dental museum-like showcases located in the lobby and the main hallway of the School of Dental Medicine, Puerto Rico (PR) are described along with important professionals who impacted on this development.

The Showcases of Dental History - A time machine in miniature at the University of Puerto Rico: Part II - The Exhibits.

The University of Puerto Rico School of Dentistry was established in 1957. Over the years, it has played an important role in Puerto Rico's healthcare system. That legacy is displayed through the walls of the School of Dentistry. In Part 1, the evolution of 20-year-old dental museum-like showcases located in the lobby and the main hallway of the school were described along with important professions who impacted on this development. In this paper, we will describe in detail the items available at the museum.

Hirudotherapy for Venous Congestion in an Almost Completely Avulsed Earlobe without Microsurgical Repair.

Venous congestion is a frequent and challenging complication after re-attachment or replantation of avulsed tissues, body parts, and flaps. It is often the reason for failure. One of the successful therapies to prevent and/or treat venous congestion is the use of medicinal leeches. There is sound evidence for its efficacy in plastic and reconstructive surgery for avulsed body parts or flaps. However, there is not enough evidence for its use in ear reconstruction or replantation, especially regarding the fragile tissue of the earlobes. The current study is the first in the literature to describe the use of hirudotherapy for venous congestion in an almost completely avulsed earlobe without microsurgical blood vessel repair, as a last resort in an otherwise healthy 38-year-old male patient who sustained trauma due to physical assault.

Dental Academic Degrees in Germany Compared to the USA.

There are different avenues for obtaining postgraduate doctoral/Ph.D. degrees in Germany and abroad. Depending on their interests and career plans, candidates can choose a postgraduate doctorate/Ph.D. that focuses on a career in academia or a doctorate that does not involve all elements of a Ph.D. and is obtained for the title's sake. Germany offers this type of diversity and flexibility, whereas the USA postgraduate doctorate model presents a more structured doctorate. The current article provides insight regarding various and more flexible pathways for obtaining a postgraduate doctorate by comparing the German and the American model. The diversity of academic degrees in dentistry and medicine, such as postgraduate doctoral degrees and the higher postdoctoral degrees available in Germany for graduates interested in academia, makes educational evaluation processes and credentials recognition challenging. The lack of transparency and a systematic approach for the academic acknowledgment of the different scientific values of each doctorate type is creating confusion, primarily when German postgraduate doctorate holders pursue academic careers internationally. The current article aims to enhance the knowledge about the different academic degrees and facilitate the educational evaluations, specialty applications, and employment processes. Understanding the additional scientific value of each doctorate type offered in Germany is imperative for their credential recognition internationally.
