The hair texture changes and hair loss are often the first symptoms of diseases of internal organs. The aim - to study the changes in hair structure, which are reflected in the quality and appearance of hair, to monitor structural changes in the hair and to evaluate the impact of diseases of internal organs in patients in order to improve therapy.Over the course of one year, 40 patients were examined who complained of excessive hair loss and 25 persons, which constituted a control group of apparently healthy people. To determine the structural changes in the root and shaft of the hair, macro- and microscopic examination was used, which was carried out on MBI-3 microscope with an AU-12 binocular attachment (600x magnification). During the examination, the root and the surface of the shaft were carefully examined for cracks or other damage. The pyruvate and pyruvate dehydrogenase tests and antithyroid antibody titer tests were used to detect latent diabetes and autoimmune thyroiditis.
Conclusion: The effect of using lotion and shampoo with dimethylsilanediol in comprehensive treatment was obtained starting from the second month of therapy, which was confirmed by microscopic examination of the hair: hair roots were covered with sheaths, a tile pattern was observed along the entire length of the hair shaft, there were no ridges or grooves. A complete structural restoration of the hair was observed in 70% of patients.

Introduction & Objectives: The COVID-19 pandemic has made adjustments both in the general life of people and in the medical practice of doctors of many specialties. In addition, doctors - dermatovenerologists at daily appointments increasingly consult users with drug-induced rashes that occurred after treatment of COVID-19. Medicinal lesions of the skin with a viral coronavirus infection are necessarily associated with a large number of drugs of various pharmacological groups prescribed to the patient, which, interacting, can have a toxic effect on human protection. One of the most important manifestations of the toxic effect of drugs on the human body is toxic epidermal necrolysis (TEN).
Purpose The research method was to analyze the anamnestic data from TEN and characterize the amino acid composition of the blood serum of such patients with damage to more than 50% of the skin area.
Materials & Methods: 6 used TENs were under our observation, during periods of various diseases (initial, acute) that had undergone COVID-19, the area of the affected skin was determined by the rule of “nines”, the amino acid composition of blood serum was determined by the method of thin-layer two-dimensional chromatography.

In order to determine the indicators of carbohydrate metabolism and their influence on the course of superficial candidiasis, 97 patients with different severity of this disease were examined.The study of carbohydrate metabolism included the determination of fasting blood sugar level to detect the overt diabetes and glucose tolerance test (with the load of 75 g of glucose).The impaired glucose tolerance was detectedin 36 patients, so their levels of
glycosylated hemoglobin and fructosamine wereadditionallydetermined.HbA1c level was determined in whole blood by ion exchange chromatography. Fructosamine was measured by kinetic colorimetric method in both serum and plasma.Blood sampling was performed on an empty stomach from the cubital vein. The studies were carried out immediately after sampling.The Sentinel CH test system from Intero (Italy) and a spectrophotometer with a 405-425 nm filterwere used for the research.
Results: The research showed that in the group of patients with candidal lesions, there is a direct dependence of HbA1c and fructosamine on the severity of the disease.In patients with minimal and moderate candidal lesions, an increase in HbA1c and fructosamine indicators was observed compared to similar indicators in the control group by 1.54 and 1.21 times respectively. In patients with significant candidal lesions and relapses, the concentration of HbA1cincreased by 2.59 timesand of fructosamineby 2.26 times in relation to the indicators of the control group.

Psoriasis is related to the systemic diseases characterised by a complex of mutually conditioned pathogenetic links (immune, neuro-endocrine, infectious, etc.). Microbiocenosis of both healthy and pathologically altered skin can serve thepoint to assess the health of macroorganism. In chronic dermatoses a qualitative
and quantitative change in skin microbial associations is observed. Changes in macroorganismare reflected in disorders of microbial landscape of all skin topographic zones. It should be noted, that the study of microbial skin flora in psoriatic patients is episodic and unstructured. Despite loads of suggested
methods and therapeutic means used to treat psoriatic patients, their efficacy remains not high due to the uncertainty of aetiology, disease pathogenesis multi-factority and polymorphism of clinical manifestations. The purpose of our study was to study changes in microbial flora of psoriatic patients skin under NBUVB application
