Since December 2019, coronavirus disease 2019 (COVID-19) has been considered a major health issue. Even in the initial days of the pandemic, dermatologists faced several challenges in preventing, diagnosing, and treating COVID-19. Like other physicians, dermatologists encountered several ethical issues. Dermatologists have served a significant role as front liners, focusing on the cutaneous manifestations of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The COVID-19 pandemic affected medical practice significantly. Due to the health emergencies caused by SARS-CoV-2, medical students’ education, patients’ prioritization, care, and cosmetic procedures were affected. Additionally, new strategies were devised to reduce the risk of transmission. This review article examines the effects of the COVID-19 pandemic on dermatology practice. We reviewed 33 articles following a search of the PubMed and Google Scholar databases for articles studying how COVID-19 affected dermatology practice.

 Psoriasis is an autoimmune and common disease that affects 1 to 3% of the world’s population. The appearance and progress of psoriasis are influenced by genetic and environmental factors. Topical steroids have remained the first-line treatment for psoriasis. Long-term use of topical corticosteroids is associated with the risk of side effects. The purpose of this study was to compare the complications and efficacy of topical clobetasol ointment with Salvia officinalis ointment in the treatment of plaque psoriasis.

 A topical ointment containing 20% Salvia officinalis was prepared in the pharmaceutical laboratory of Hormozgan University of Medical Sciences. After standardization, this experimental study was performed on 84 voluntary patients with mild plaque psoriasis for two weeks. One group was treated with the prepared S. officinalis ointment twice daily and the other group was treated with topical clobetasol ointment twice daily. In each group, psoriasis severity was assessed using the Psoriasis Area Severity Index (PASI) at determined time points including baseline and one and two weeks after treatment initiation.

 At the end of treatment (2 weeks), the mean PASI score changed from 2.36 to 1.55 in patients who received topical clobetasol ointment and this score reduced from 2.74 to 2.23 in patients who applied topical S. officinalis ointment. After 14 days of treatment, the mean percentage decrease in mean PASI score was greater in patients who applied topical clobetasol ointment.

 This study provides evidence that topical clobetasol ointment is more effective than 20% S. officinalis ointment in the treatment of psoriasis. However, S. officinalis ointment can be used as an adjuvant therapy to the main treatments of mild plaque psoriasis.

Mind mapping is a visual mapping technique used in a few disciplines of medical education to represent ideas linked to and arranged around a central core idea or topic through different subtopics/categories. We aimed to utilize this technique to teach the undergraduate medical students the morphology of skin lesions and assess its effectiveness. This pre- and post-test quasi-experimental study was done among 144 undergraduate medical students. A total of 144 students were selected, and odd and even roll numbers were categorized into two groups using simple random sampling. Group 1 (intervention group) students were taught using mind mapping technique and Group 2 (control group) with traditional lecturebased teaching. A Computer-Assisted pre-test and post-test were carried out. A feedback questionnaire was administered to the intervention group to explore the students’ perceptions regardingmind mapping as a learning tool. The data were analysed using SPSS software (version 16), and the difference in the mean preand post-test scores was found using independent sampled-t-test. Pre and post-test score distribution was 5.04±1.27 and 11.44±2.52 (P≤0.001), respectively, in the intervention group. In the control group, the pre and post-test score distributions were 4.83±1.39 and 8.04±1.63, respectively. The mean rank of the mind mapping group was higher (76.43) than the lecture group (67.5). Among the students, 97.2% agreed on the fact that mind mapping enhanced their interest in learning, and 91.7% of the students were satisfied with mind mapping as the learning method. To kindle the interest and develop critical thinking skills in students, faculty members should continue to explore and evaluate the efficacy of various learning and teaching strategies. Mind mapping could be a novel and integral part of conventional teaching techniques in medical education as evidenced by our student’s performances.

 Neurofibromatosis type 1 (NF1), a genetic condition most commonly characterized by the presence of dermal neurofibromas and café au lait macules, has a significant impact upon the Quality of Life (QoL). The purpose of this study is to predict the QoL with Dermatology Life Quality Index (DLQI) in Iranian patients with neurofibromatosis type  .1

 This cross-sectional study was conducted on 223 patients with neurofibromatosis type 1 using available sampling. Data collection tools were demographic information form, SF-36 and DLQI questionnaires. Quality of life was predicted by DLQI. Linear and multiple regression tests were utilized to analyze the data. 

  Predicting the quality of life by dermatology quality of life showed that the physical function by the variable “work and school” and treatment, role limitations due to physical health by the variable of work and school, the role limitations due to emotional problems by the variable of treatment, emotional well-being by the variable of interpersonal relationships, pain by the variable of symptoms and feelings, daily activities, and personal relationships were predictable. Finally, social function, general health and fatigue cannot be predicted by any variable.

 The results of this study indicated that the quality of dermatology life is able to predict some aspects of quality of life. These findings can be used to provide better health services to this group of patients and improve their quality of life.

Despite its vast benefits, the establishment of telemedicine, especially teledermatology, faces many problems due to several reasons.The present study was carried out with the purpose of psychometrics measurement of the factors affecting the establishment of teledermatology.

The present mixed-method (qualitative and quantitative) study was carried out through triangulation in 2018. The research population comprises experts and managers of the health system of Iran. Cronbach's alpha test was used to assess the internal consistency, and the external reliability was measured by the test-retest method.The significance level throughout the whole analysis was P<0.05.

According to the scree plot, the eigenvalues were greater than 1 and the slope of the scree plot, 8 factors with the potential of predicting the 69.52% of the total changes of the factors of the establishment of the telemedicine were extracted and selected. Cronbach's alpha test was employed to determine the internal consistency of the questionnaire, which was approved with the amount of 0.941 (higher than 0.7).

The results indicated thatthe 58-article measurement scale for the factors influencing the establishment of teledermatology has good validity and reliability. According to factor analysis, it includes 8 subscales. Cronbach's alpha coefficient was calculated to be equal to 0.941.

The nail bed is a fundamental structure of the nail unit. Given its close relationship with the nail plate, the distal matrix, and the hyponychium, how it interacts with these structures is still a matter of study.

We describe clinical cases of patients with traumatic destruction of the nail bed treated with mechanical dermabrasion in a reference center. Both clinical cases had a satisfactory response to the treatment, which supports the proposed theories about the functioning of the nail bed.

The nail bed is a dynamic tissue that closely interacts with adjacent structures and responds to forces applied to it.

Gardnerella vaginalis and Candida albicans are the most common causative agents of bacterial vaginosis, and infections with these pathogens lead to inflammation, endometritis, and pruritus. The aim of this retrospective study was to determine the trends of G. vaginalis infections based on real-time PCR data according to age and sex in patients with sexually transmitted diseases.

A total of 59,381 specimens isolated at a clinical laboratory from September 2018 to December 2020 were subjected to real-time PCR for the detection of G. vaginalis DNA. Sample types included catheter, pus, tissue, swab, and urine samples.

Among 59,381 samples, 20,718 (34.8%) were positive for G. vaginalis. Of the positive samples, 13,186 (63.7%) were from male patients and 7,532 (36.3%) were from female patients. Average patient age was 39.1 years (the average age of male and female patients was 38.34 and 40.43 years, respectively). Female patients younger than 19 years exhibited the highest incidence of G. vaginalis, at 71.57%, followed by 68.46% incidence in those aged 20-29 years; the lowest incidence was in women aged 40-49 years. Further, among specimen types, the highest number of G. vaginalis-positive specimens was obtained by the swab sampling method.

From 2018 to 2020 in Korea, the number of tests conducted for bacterial vaginosis has increased, while the incidence of G. vaginalis infections appears to have decreased. the finding that female adolescents have a high tendency to carry the pathogen is important. and for effective surveillance of BV, sampling by cotton swabs and detection by multiplex PCR might be a good approach.

Coronavirus could affect almost any part of the body including the skin. In this systematic review, the primary skin lesions resulting from the direct activity of the virus or the medications used for treatment and the changes in the behavior of the virus regarding the occurrence of these symptoms over time were assessed. PubMed/MEDLINE, Embase, PsycINFO, TRIP Cochrane, Cochrane Skin were searched for all published articles from February 19 to July 1, 2020, which met the inclusion criteria. Thirty-six related articles were extracted. Twenty-eight studies reported virus-related mucocutaneous eruptions and 8 articles, the drug-reactions. Data of 583 patients were included. Skin lesions of COVID-19 could be caused by both the virus itself or the influence of drugs used for the treatment. Morbilliform rashes, urticaria, and acral-vasculopathic cutaneous lesions were at the forefront of primary COVID-dependent skin lesions with no significant change during time, Also, Hydroxychloroquine, lopinavir/ritonavir, paracetamol, and antibiotics were reported as the main causes of drug-induced rashes. Since dermatologic manifestations may occur prior or simultaneously/after other COVID clinical symptoms, so they may helpful in patients’ early diagnosis or prediction of internal organ involvements via histopathologic evaluations of skin biopsies especially about vasculopathic and vasculitic, respectively.

Medical images have been widely used for various aims, especially for the educational purposes. Patient confidentiality and consent should be deemed crucial. In this study, we sought to assess patients’ satisfaction with taking medical photos of their skin lesions and giving their physicians consent to use them for educational purposes.

This multi‑method study included quantitative and qualitative phases and was performed from April to November 2018 in the Dermatology Department of Shiraz Faghihi Hospital in South Iran. Demographic information was analyzed using the descriptive statistics. To resolve the simultaneous effect of demographic variables on patient satisfaction, we conducted linear regression. All the tests were analyzed at the 0.05 significance level.

In this study, all the patients except one (99.5%) preferred that only a physician who had a direct role in their care can access their digital photos. Of 200 patients, 134 patients (62.33%) preferred the utilization of hospital cameras in photographing their skin lesions (P = 0.002). On the other hand, 131 patients (49.81%) did not gave consent about using a personal phone camera for photographing their skin lesions (P = 0.001). In the qualitative phase, two major themes (trusting attending physician and paying attention to patient confidentiality) and five sub‑themes (considering their physicians as professional people who always do the right thing, allowing physicians to use their images for educational purposes, covering patient’s face, using hospital cameras, and obtaining informed consent from patients) were derived from qualitative semi‑structured interviews.

The results showed that there is a need for developing international and national photography guidelines in the era of technology development.

Functional dyspepsia (FD) is a common disorder of the upper gastrointestinal tract. Several documents in conventional medicine claim an association between FD, sleep disturbance, and some dermatological conditions, but there is still debate about these relationships. This study aimed to measure the association between FD and some skin problems and sleep indices based on the attitudes of traditional Persian medicine.
This study was carried out on patients with the diagnosis of FD and healthy people. The study populationconsisted of patients who referred to the gastroenterology clinic of Shiraz University of Medical Sciences (Shiraz, Iran) from July to December 2019. To diagnose dyspepsia, we used Rome III criteria. Skin problems and sleep indices were evaluated using a validated researcher-made questionnaire. P-values of ≤0.05 were considered significant.
Overall, 160 patients (46 men and 116 women) with FD and 155 healthy individuals (36 men and 119 women) were enrolled in the study. There were significant differences between patients and healthy individuals in terms of dryness of skin (P = 0.001), oily hair, deep sleep, long sleep, insomnia, difficulty sleeping, and nightmares (p≤0.001). On the other hand, there were no significant differences between the groups in intermittent sleeping (P = 0.116) and periorbital edema after sleeping (P = 0.195).
According to the results of this study, it seems that there is a positive relationship between FD and some dermatological and sleeping indices based on traditional Persian medicine resources.

The National Examination of Knowledge in Medicine establishes the knowledge profile (PdC) a physician must possess to practice public medicine in Chile. However, no study has evaluated the perception of dermatology training regarding the acquisition of the minimum competencies required. This study described and compared the impressions of the dermatology training received by the University of Chile (UCh) graduates with graduates from other national and international faculties of medicine.

This was a cross‑sectional study, based on a single survey model, applied via E‑mail to registered physicians in an online database, with emphasis on UCh medicine graduates, from the generations 2012 to 2016. The data were collected anonymously, tabulated, and analyzed in MINITAB.

From 908 UCh graduates, 141 surveys were answered (15.5%). Nine of 10 physicians considered “important” to obtain knowledge in dermatology. About 68.8% found the information they received was adequate. When comparing UCh graduates with other Chilean universities, UCh graduates had a slightly better impression of their training. When comparing Chilean versus foreign graduates, the latter presented a better perception of their preparation in cutaneous pathology.

UCh graduates were satisfied with their dermatological training at the undergraduate level and felt better prepared than colleagues from other Chilean universities when facing cutaneous pathologies.

Metabolic syndrome (MeTS) is a well‑known health‑related problem with several end‑organ damages and the resulted side effects such as rising in the blood glucose and lipid and blood pressure. Although MeTS might show several skin symptoms such as acanthosis nigricans, skin tags, acne, and androgenic alopecia, it could also be implicated in the pathophysiology of numerous dermatologic disorders. Furthermore, some dermatologic drugs might be implicated in the incidence or exacerbation of MeTS. Consequently, MeTS and skin problem could interfere closely with each other and each one could predispose the patient to the other one and vice versa. Remembering these close relationships help us to have better therapeutic choices regarding each inflammatory skin conditions. Moreover, some of the skin symptoms should be followed cautiously to define the underlying MeTS.
