Chronicles of A.I. Pospelov Moscow Society of Dermatovenerologists and Cosmetologists (MSDС was founded on October 4, 1891) Bulletin of the MSDС № 1158

On May 17th we held our last meeting of Moscow Society of Dermatologists and Cosmetologists named after A.I. Pospelov in person within XLI Rachmanov Readings conference. There were 61 participants. Our agenda included two clinical cases: the first one was dedicated to the PASH-syndrome as the most common manifestation of gangrenous pyoderma syndromic form; the second one was about diagnostic difficulties in mycosis fungoides. The first report was accompanied by the presentation of clinical cases of PASH syndrome (gangrenous pyoderma, Hoffmann's folliculitis, suppurative hidradenitis) in a patient aged 19 years and gangrenous pyoderma combined with suppurative hidradenitis and conglobate acne in a patient aged 32 years. The main treatment was the administration of methylprednisolone in combination with antibiotics and the addition of a cytostatic in the second clinical observation. Two reports were presented in the scientific part of the meeting. In the first report (on the experience of using bacteriorhodopsin in patients with psoriasis vulgaris), the author demonstrated the results of his own prospective study of bacteriorhodopsin cream, noting that the fastest effect occurred on open skin areas. A special emphasis of the second report (on tattoos in the practice of a dermatologist (Fomin Clinic) was made on the absence of a list of contraindications, mandatory certification of dyes for tattooing and tattoo master's workplace, standard of preliminary laboratory tests, as well as uniform requirements for specialists performing tattooing, which determines the frequency of infectious complications after the procedure.
