This is an abstract of the review of the second edition (2017) "Tropical DERMATOLOGY" published by Elsevier (ISBN-13: 978-0323296342) and edited by three distinguished tropical dermatologists: Professor Stephen K. Tyring, University of Texas Health Science Center, Houston, Texas; Professor Omar Lupi, Federal University of Rio de Janeiro, Rio de Janeiro, Brazil; and Professor Ulrich R. Hengge, University of Düsseldorf, Düsseldorf, Germany.The book intends to address the needs of dermatologists, infectious and tropical diseases specialists, and travel medicine physicians for updated and practical information on tropical DERMATOLOGY conditions. It is consisted of 36 chapter in 463 pages.Of interesting points about this book is its first chapter, which provides a "syndromal" approach to tropical skin conditions facilitating approach to the patients and making differential diagnoses. Chapters two and three provide guidance for the travelers and who are going to work in tropics from a pragmatic point of view. The contents of those two chapters are of significant preventive importance. Another point of strength of "Tropical DERMATOLOGY" is providing information on emerging infectious diseases as well as Zika, Ebola, and Dengue fever diseases, which got importance over the past couple of years mainly because of changes in their epidemiology. The chapter on poxviruses was very well written too. Another important feature of this book is its wonderful illustrations. With over 650 full-colored illustrations, all clinical photos, photomicrographs, flowcharts, and tables help the reader to achieve a rapid and deeper understanding of the content. Another strength of "Tropical DERMATOLOGY" is its well coverage of both common and rare diseases.I recommend this book to all resident and practicing dermatologists, infectious diseases and tropical diseases specialists, and those who are dealing with travelers or intend to work in tropics.

Erythromycin was the first macolide discovered in 1952. In 1990s new macrolides including clarithromycin, azithromycin, and dirithromycin were introduced to the market. We provide a review of their structure, pharmacokinetics. mechanisms of action, and indications in DERMATOLOGY.

The main challenge for training in cosmetic DERMATOLOGY is the difference in the attitudes of residency programs and residents about the necessity and amount of education during the residency period. A national online survey conducted between September 6th and November 21st, 2017. Residents, members of the Iranian Board of DERMATOLOGY, faculty members and program directors (PDs) were asked to participate in the survey. 174 participants from 12 residency programs participated in this study and the response rate of residents, professors, and DERMATOLOGY Board Directory Members (Boardmans) and PDs was 89. 8%, 61. 7%, and 81. 8%, respectively. Residents declared greater tendency towards practicing medical DERMATOLOGY (mean score, 5. 165± 0. 8335) over the five years after graduation than that of was perceived by professors (4. 043± 1. 2988), and Boardmans and PDs (4. 059± 1. 0290) (P˂ 0. 001). The first residents’ priority was practicing in medical DERMATOLOGY (5. 165± 0. 8335) during 5-years after graduation. However, professors (5. 261± 0. 8282) and Boardmans and PDs (5. 176± 0. 7276) predicted residents' first priority would be practicing cosmetic DERMATOLOGY (P˂ 0. 001). Forty one (60. 3%) of the professors, Boardmans, and PDs agreed or strongly agreed that residents’ desire to learn more about cosmetic procedures resulted in their decreased interest in learning medical procedures (P=0. 18). Medical DERMATOLOGY is still clearly the basis for training in residency programs, and even for residents who have a high tendency to practice cosmetic DERMATOLOGY, there is a strong tendency to work in the field of medical DERMATOLOGY as well.

Since the discovery of X-rays, the use of imaging technology has continued to play an important role in medicine. Technological advancements have led to the development of various imaging modalities, most of which have been used to image organs deep within the human body. More recently, attention has focused on the application of imaging technology for evaluation of the skin. A variety of techniques are currently being used to examine the skin and these include specialized photography, surface microscopy, ultrasound, laser Doppler perfusion imaging, confocal microscopy, magnetic resonance Imagmg and optical coherence tumography. These modalities can provide information that can assist in the management of skin problems. Although many of these techniques are still undergoing research, they are showing promise as useful clinical tools in DERMATOLOGY. In this review article we discuss about each of these technologies in brief.
