The variety of dermatological manifestations in patients with the novel coronavirus infection COVID-19, the incidence of which depends on concomitant pathology and the characteristics of drug treatment, and their characteristics are similar to those that occur with conventional viral infections is discussed. At the present time it is proposed to distinguish several groups depending on the cause and mechanism of development: angiitis of the skin; papulo-squamous rash and pink lichen; measles rash and infectious erythema; papulo-vesicular rash; toxidermia; urticarial eruptions and artifical lesions. The variety of the clinical picture of the skin manifestations of coronavirus infection requires in-depth analysis in order to interpret correctly the skin lesions and other infectious exanthema and dermatoses in patients with COVID-19.

Early detection of melanocytic nevus progression to malignant melanoma is a pressing concern. Traditionally, patients with multiple melanocytic nevi (MMN) are monitored for extended periods of time and excisional biopsies are performed on individual suspicious melanocytic nevi (MN). This approach is costly and tremendously time-consuming for both doctors and patients. The aim of this study was to evaluate the efficacy of a smartphone-compatible optical instrument in the assessment of MN for malignancy. Seven patients aged 43 to 65 years with MMN on the trunk and upper/lower extremities were followed-up for 4 years. Dermoscopy images of MN were taken and analyzed using a Handyscope smartphone-compatible optical system operated at 20x magnification and a Handyscope3 application. A total of 74 MN were surgically removed during the follow-up period. None of the patients had melanoma. The results of dermoscopy image analysis generated by the convolutional neural network coincided with histopathology findings in all cases. The optical Handyscope system demonstrated its efficacy in assessing MN for malignancy. AI can be used for primary screening of MMN dermoscopy images. However, histopathological verification of the diagnosis is still needed.

Chronic noninfectious diseases (cardiovascular, bronchopulmonary, oncological diseases and diabetes mellitus) are presently the most common cause of death worldwide, with cardiovascular diseases (CVD) being predominant. For this reason, the key goal of a physician is not only to treat but also to prevent diseases. Acetylsalicylic acid (ASA) is considered one of the most effective drugs for secondary prevention of CVD. However, the use of ASA for primary prevention is still debated. Results of many studies of ASA are inconsistent. Some studies have suggested that using ASA in patients aged 40-70 with a high 10-year risk of CVD and a low risk of bleeding may reduce the incidence of CVD. Administration of ASA to patients with a high or medium risk of CVD is also considered.

Due to the changes in the modern world, it is necessary to develop the domestic pharmaceutical industry, which is a task especially important in the context of implementation of the import substitution policy. The article classifies the main measures the state industrial policy has for the pharmaceutical industry; these measures cover informational and consulting aspects, research and technical parts, innovations and economic matters. Practical actions and their possible consequences are considered for each group of the industrial policy measures: encouragement of domestic consumption, regulation of imports, stimulation and support of exports, stimulation of technological development, public-private partnerships, support of the development of intersectoral territorial production complexes (clusters), direct state support of investment activities, tax incentives for investors.
