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.

The relationship between disorders of iron metabolism and alopecia, in particular telogen hair loss (THL), remains poorly understood and requires further research. Goal. To assess changes in the dynamics of growth and hair condition in women with an iron deficiency state during systemic therapy with iron supplements in combination with and without physiotherapy. Methods. An open-label, randomized, comparative interventional study with a duration of 6 months included 26 female aged 19 to 54 years (38.8 8.9 years) with complaints of hair loss, changes in their structure, dryness and / or hair brittleness; with preserved menstrual cycle and mild iron deficiency anemia (IDA, Hb 101120 g/l). Trichoscopy and phototrichogram were performed with processing of the results in the TrichoScienceProv1.1 program. The changes in the dynamics of hair growth and condition were assessed against the background of the use of iron supplements in combination with physiotherapy and without physiotherapy. Pulsed alternating sinusoidal current of high frequency, high voltage and low strength was chosen as a physiotherapeutic method for the treatment of THL. Results. Against the background of the therapy, an increase in the Hb level (p 0.001) and a positive dynamics of trichological parameters in all patients were noted, the severity of which was higher when the therapy with iron supplements was combined with physiotherapy. Conclusion. Our findings confirm that the complex treatment of patients with telogen alopecia on the background of an iron deficiency state may achieve positive dynamics of trichological indicators.
