The presence of acne leads to cosmetic defects of the face, which greatly reduces a person's self-esteem. Therefore, it is relevant to assess the risk factors for acne in females (n=176). We analyzed possible risk factors for akne: bad habits, eating behavior, features of physiological processes, the presence of metabolic disorders. Results: Stress was the cause of acne in almost 2/3 of cases. Approximately in equal amounts, the causes of acne in women were the alimentary factor, metabolic disorders, and smoking. Approximately half of the cases of acne vulgaris contributed to the onset of menstruation and alcohol consumption. Conclusions: Knowing and identifying the causes of acne is the first step to preventing and treating it.

Background: Modern Russian statistics show that the percentage of renal cell carcinoma (RCC) among all oncological diseases has increased and amounted to almost 5% in 2019. The main method of treating RCC is radical nephrectomy in localized RCC, which is supplemented by the removal of regional lymph nodes in locally advanced RCC. Aim: To evaluate early and late postoperative complications in patients with localized and locally advanced renal cell carcinoma. Methods: We’ve analyzed the results of surgical treatment and postoperative complications in 378 patients with clinically proven localized and locally developed RCC. Results: The total number of complications after surgical treatment of patients with localized and locally advanced RCC was 24 (6.3%) patients. Moreover, in the treatment of the localized form of RCC, postoperative complications are 3 times less common than in the locally advanced form of RCC (p <0.05). The most common complication after surgical treatment of RCC was bleeding which we observed in 11(2.9%) patients. Conclusion: After surgical treatment of RCC, the proportion of complications is not high, but they can have unpleasant consequences. In the late postoperative period the most common complication bleeding is followed by lymphorrhea and urinary tract infections.
