Dermoscopy is a widely used tool for the diagnosis of pigmented skin lesions. The use of dermoscopy is increasing in popularity amongst dermatologists, making it necessary to better understand dermoscopy and to analyse why physicians use it or do not use it. The survey indicated that the majority of physicians used dermoscopy in order to reduce patient anxiety and to detect melanoma early. The main reason why dermatologists found dermoscopy to be ineffective was that they felt that it was not useful in detecting melanoma earlier than traditional methods; 35% of dermatologists surveyed believed that dermoscopy required excessive training. These results imply that current training methods need to be modified. Training is limited to large dermatology centers and is not being transferred to general centers, which would allow it to be more accessible to a larger group of dermatologists in training. There is also a need to make the learning of dermoscopy easier and to establish a universal method of teaching. Overall, there is a need for improvement in the education of dermoscopy, ranging from training to information on the basics of dermoscopy. This would include aspects such as how long the average examination takes and dermoscopy's effectiveness compared with alternate methods.

McKinsey Global Institute (2017) in its report states that construction-related spending accounts for 13% of the world’s GDP, but the sector’s annual productivity has only increased 1% over the past 20 years. As with all other industries, as years pass innovation is intended to increase and introduce much higher productivity levels and safer work environments. It has been more than a decade of BIM utilization in construction jobsites. The introduction of three-dimensional modeling was supposed to serve as the turning point regarding technology in construction, but have we truly seen the effective utilization of BIM in construction process? So, what are the roadblocks to a smoother transition from paper-based 2-D to electronic 3-D Models in construction job sites? Utilizing both a questionnaire survey and an in-depth interview technique, this study explored the reasons behind the slow adoption and apprehensions in adopting 3-D Models in construction projects. Ineffective and lack of training in BIM was found to be one of the reasons for less than slower adoption of the BIM in construction job sites.

Atypical acquired melanocytic nevi in patients with epidermolysis bullosa (EB) have been referred to as EB nevi and are considered to be a type of recurrent nevus with atypical but distinctive histopathologic findings. Herein, we describe an atypical nevus in a patient with Hailey-Hailey disease with different histopathologic findings from EB nevi because of presumably different pathogenesis. It is important to be aware that the recurrent nevi phenomenon can be seen in acantholytic conditions as well as blistering disorders, given these lesions may clinically resemble melanoma.

Thus far there have been very few cases that document such a rarity as the same cancer occurring in monozygotic twins, at the same time, in the same location. We report this extraordinary phenomenon in our patients, 71-year-old identical female twins, presenting with melanoma at the same time (within 10 days of each other) and location (the right calf).
