So far in the history of mankind, the pandemic has been declared only twice. The first was the H1N1 influenza pandemic of 1918-1920, known as the “Spanish flu” or “Spanish”. The second is the 2009-2010 H1N1 flu pandemic, referred to in the media as “swine flu”. At the end of 2019, there was an outbreak of a new coronavirus infection COVID-19 with an epicenter in the people’s Republic of China (PRC) in the city of Wuhan (Hubei province), and since the beginning of 2020, cases of a new coronavirus infection have been recorded in other countries whose citizens visited the PRC. In some territories, such as South Korea, Iran and Italy, the epidemiological situation for COVID-19 has sharply worsened, which subsequently led to a significant increase in the number of cases in the world associated with travel to these countries. In connection with the current epidemiological situation, on March 11, 2020, the Director-General of the world health organization (who), Tedros Adhanom Ghebreyesus, said at a briefing in Geneva that the spread of the new coronavirus in the world has become a pandemic. According to experts, the new coronavirus infection has a number of features, both epidemiological and clinical. Currently, information about this is quite limited, which makes it difficult to prevent and treat this disease. In our article, we tried to present some aspects of the new coronavirus infection COVID-19, referring to data published in open scientific literature sources, and reporting data from two administrative districts of the city of St. Petersburg.

The article briefly presents the literature data and a description of the clinical dynamic observation of a patient with severe hypoxic brain damage (from the neonatal period to 4 months of life), in the conditions of the neonatal intensive care unit. The article describes the clinical picture, features of paroxysmal states and antiepileptic therapy, dynamics of neuroimaging data, electroencephalographic phenomena recorded in a patient with cerebral depression and structural cerebral injuries. The significance of electroencephalographic examination in the intensive care unit as an informative method for assessing cerebral activity in young children with central nervous system depression syndrome is shown. Disorganization of background activity, indicating structural cerebral damage, long-term persistence of slow-wave activity, detection of epileptic changes in the form of generalized flashes of pointed waves in the theta range, alpha-coma pattern, subsequently replaced by suppression of the background pattern in the patient, are typical electrophysiological disorders recorded in severe hypoxic encephalopathy. In conditions of limited opportunities for visual diagnosis of a patient with impaired consciousness, EEG remains the only method of obtaining information about the functional state of the brain, the data obtained during the study are an important prognostic criterion.

Among skin diseases in children and adolescents, the most common pathology is acne. The main pathogenetic link of acne in adolescents is hormonal imbalance. The effect on the sebaceous glands of high concentrations of dihydrotestosterone causes a change not only in the quantitative but also in the qualitative composition of the sebaceous secretion. The study is devoted to assessing the characteristics of sexual development, immune status and biochemical parameters in boys suffering from acne. Materials and methods.

Materials and methods. A comparative analysis of the state of immunity, sexual development, biochemical parameters of 147 boys suffering from acne, and 142 healthy boys who do not suffer from acne.

It was found that the immune status of boys suffering from acne was characterized by a decrease in cytotoxic lymphocytes. In the peripheral blood of these boys, serum interferon γ, tumor necrosis factor α, interleukins 1, 2, 8 and 10, as well as small circulating immune complexes were significantly higher than in the boys of the control group. In boys suffering from acne, in the puberty period, the concentration of prolactin in 13–14 years is significantly lower, and testosterone levels are significantly higher than in boys of the control group of the same age. At 15–17 years of age, the concentration of luteinizing hormone in boys with acne is significantly lower, and testosterone is higher than in boys in the control group. Evaluation of the degree of formation of secondary sexual characteristics indicates that boys suffering from acne differed from their peers from the control group by a small advance in sexual development. Thus, boys suffering from acne, characterized by advanced and disharmonious puberty.

Radio-sensitizing compounds are used to increase radiotherapy effectivity and reduce negative pathologic systemic effects of radiation. These radio-sensitizers selectively pile-up in tumor tissue and enhance necrobiotic processes caused by irradiation. Unfortunately, broad introduction of radio-sensitizers into clinical practice is hampered by their low effectivity and substantial negative side effects. This what determines radio-sensitizers effectivity studies high actuality in a colorectal cancer mice model. The study involved 156 male BALB/c mice who had been transplanted with colorectal cancer. After the transplantation they were injected with acridineacetate – containing compounds Cyclopherone and Procitol. A comparative assessment was undertaken of tumor growth dynamics and metastatic rate. A combination of gamma-irradiation with radio-sensitizing compounds produces a more substantial therapeutic effect according to all parameters of the experimental colorectal cancer growth and development than the isolated effect of radiotherapy or antitumor drugs. A considerable slowing down of tumor growth on the 14^th and 28^th day of the study was revealed as well as a reliable inhibition of lymphogenous and hematogenous metastatic spread of neoplasma during the entire study and a statistically valid increase of lifespan of the experimental animals. The radiosensitizing effect of Procitol in combination with radiotherapy turned out to be more substantial than that of Cyclopherone.

An increase in the number of patients with psychodermatological manifestations and the identification of a certain comorbidity during the course of diseases in patients with a dermatological profile makes us take a fresh look at this problem. Psychodermatology is one of the relevant and, at the same time, the least studied areas of modern medicine, which is at the junction of psychiatry and dermatovenereology. Psychiatry and psychotherapy studies the inner world of a person; Dermatovenerology deals with the diagnosis and treatment of diseases of the human skin and its appendages, and psychodermatology combines these two sections of medicine. In the modern world, as a result of increasing the amount of incoming sensory information, accelerating the rhythm of life, the action of harmful environmental factors, a person can be subjected to excessive psycho-emotional stress, leading to the development of mental disorders. Often it is skin rashes that are an objective manifestation of such disorders. Early diagnosis of psychodermatosis and signs of obsessive-compulsive pathology in sick people contributes to the timely identification of the category of people at risk of psychotic reactions and mental illness. This is especially true for young patients. Against the background of hormonal changes in the body, the crisis of adolescence, the increased educational load on them at school, the destroyed institute of family and marriage, an overabundance of sensory information and physical inactivity, the incidence of psychodermatosis throughout the world, including in our country, is increasing.

Mumps currently is a vaccine-preventable infections. However, mumps still remains an urgent problem all over the world, due to periodic increases in the incidence in older children (including the vaccinated ones against this infection), in adults (the disease often does not go smoothly with involving various organs in the pathological process and systems). The literature describes the various adverse effects of male mumps, including infertility, testicular atrophy, testicular tumors, impotence, gynecomastia, etc. The article provides information on the incidence of mumps in the Russian Federation and St. Petersburg, the clinical manifestation of the infection. It was noted that in adolescent boys and men, the presence of orchitis (orchoepididymitis) is a frequent symptom of the disease. It is shown in the article, that testicular inflammation rate increases with age of patients. A brief description of modern methods of laboratory diagnostics and therapy is given in accordance with clinical recommendations and treatment standards. A clinical case of mumps, combined severe form (mumps + orchoepididymitis), in a 17-year-old boy is presented in this article. The features of the course of the disease, the results of laboratory and instrumental examination and treatment have been analyzed in this item. Conservative therapy (antiviral and antibacterial) of mumps, as well as timely surgical treatment of orchoepididymitis, led to a complete clinical and laboratory recovery of the patient.

The appearance of this work governs by the modern requirements of the Russian Federation legislation, including Federal Law of 29.12.2012 No. 273-FL “Education in the Russian Federation”, Federal State Educational Standard, SanPiN and other regulatory acts of the Russian Federation Government with necessity to expand the network of preschool educational organizations having groups for young children and creating groups for infants starting from 2 months. The authors of the article analyzed the existing conditions in preschool organizations in our country and abroad. It is shown that in order to maintain health, successfully adapt and develop an infant and young child to preschool organizations, create groups for children up to a year old, it is necessary not only to bring the existing legal framework into line, but also to conduct a significant reorganization of the structure of preschool organizations, with the aim of creating adequate conditions for infants without harming the health of the newborn child and the social well-being of the family. It emphasizes the need to provide parents with recommendations for protecting health and preparing the baby for kindergarten by providing targeted financial assistance to parents for a conscious choice between home education and training in the context of early childhood care. Serious financial support is also required for preschool organizations to equip buildings and territories for the care, upbringing and safe development of children of this age. The need for the return of pediatricians, nurses, speech therapists, educators, psychologists to the staff of preschool organizations is emphasized that is the need for review in the direction of increasing staffing levels. A comparison is made of the preschool educational organizations work organization abroad and in Russia. Some features of the young children and infants psychophysiological and physical condition are briefly reviewed, and necessary recommendations are given to parents. The article discusses the possibility of improving the adaptation period to preschool educational institutions in Russian Federation without harming the health of young children and infants.
