chemotherapy, provision of safe water supply and sanitation facilities are recommended. Furthermore, health education should be encouraged within schools and communities.Immune checkpoints assist with self-tolerance and minimize collateral tissue damage when immune responses are activated. Although immune checkpoint inhibitors (CPIs) are characterized by a favorable risk/benefit ratio, immune checkpoint blockade has been associated with a new subset of autoimmune-like toxicities, named immune-related adverse events (irAEs). Dermatologic reactions are among the most prevalent irAEs triggered by CPIs. In a majority of cases they are self-limiting and readily manageable. However, it is not uncommon that they result in severe skin involvement and impairment of patients’ quality of life. Awareness of the spectrum of cutaneous irAEs is mandatory for every clinician involved in the management of oncologic patients. The role of the dermatologists is essential because early recognition and appropriate management of skin toxicity may prevent dose modifications and discontinuation of CPIs. The latter is particularly relevant, considering that recent data suggest favorable oncologic response in patients developing irAEs.

The International Dermoscopy Society (IDS) conducted an online survey to investigate the impact of coronavirus disease 2019 (COVID-19) outbreak on the daily practice of dermatologists working with skin cancer patients, to collect data regarding the frequency of skin manifestations noticed by the members, and to obtain information about the use of teledermatology during the pandemic.

All IDS members were asked to fill in a questionnaire, sent by email. A questionnaire available in English was sent to all IDS members (≈16.0000 members) by email. The questionnaire was anonymous, with a compiling time of less than 5 minutes. see more The survey was open for 30 days (from April 24, 2020 to May 24, 2020) and it could only be filled out once.

Overall, 678 dermatologists responded to the questionnaire; 334 members stated that there has been a reduction of more than 75% in daily work activity during the pandemic, 265 dermatologists worked fewer days per week, and 118 experienced telemedicine for the first time. Acrodermaver, our study confirms earlier findings of a wide range of skin manifestations associated with COVID-19.

The primary objective of this study was to determine the diagnostic accuracy and effect of an educational training on skin cancer course and dermoscopy use among primary care physicians in rural areas of Colombia. The secondary objective was to assess the diagnostic accuracy of skin cancer diagnosis and detection rate after 3 months of the initial training.

Twenty-one primary care physicians from 6 rural areas of Colombia participated in a 2-day skin cancer and dermoscopy training, followed by a day-long hands-on session on dermoscopy at a free skin cancer screening event. Pre- and post-tests were performed using clinical and dermoscopic images to evaluate the user’s ability to diagnose and differentiate benign and malignant neoplasms. In addition, participants’ levels of confidence were assessed.

After the training, the sensitivity and specificity of characterizing skin lesions as benign or malignant or providing a specific diagnosis (ie, angioma, seborrheic keratosis, basal cell carcinoma, etc.) increased by 23.6% (62.9% to 86.5%; P < 0.0001) and 21% (54.7% to 75.7%; P < 0.0017), respectively. In addition, levels of confidence when diagnosing skin lesions changed from extremely low or low, to high or extremely high by 20.7% (38.3% to 59%) using dermoscopic images (odds ratio (OR) 3.22; 95% confidence interval (CI) 2.67-3.86; P < 0.0001). The secondary objective was not achieved due to loss of follow-up of the majority of participants.

Providers serving populations with limited healthcare access may benefit from education in diagnosing and differentiating skin cancer with the use of dermoscopy, which may ultimately improve patient care and reduce healthcare costs.

A total of 30 patients (7 male, 23 female) were included in the study. Dermoscopic examination was performed on both the clinically most severely affected areas and adjacent healthy skin. The skin surface biopsy sample was taken from the same place from where the dermoscopic image was taken.

A total of 83 (lesion n = 60, non-lesion n = 23) areas were evaluated.

Guttate psoriasis (GP) and pityriasis rosea (PR) are a part of papulosquamous disorders that have very similar clinical features and often require histopathology to confirm the diagnosis. Dermoscopy has emerged as a noninvasive, cost-effective technique that can aid in the diagnosis of inflammatory skin diseases like GP and PR.

To study and compare the dermoscopic features of GP and PR.

Twenty consecutive patients each with GP or PR were enrolled in the study. The diagnosis of GP and PR were made clinically and on histopathology. Dermoscopic images were taken of the representative lesions from each patient using a manual dermoscope attached to a digital camera after applying ultrasound gel. Vascular morphology, vascular arrangement, background color, along with color and distribution of scales were noted in each case. Statistical analysis was done using chi-square test to determine the significance of findings in both groups.

The combination of a bright red background with dotted vessels in uniform diffuse distribution with diffuse white scales was highly specific for the diagnosis of GP.
