The article presents 3 clinical observations of women of 51, 55 and 57 years old with severe rosacea, who reached the state of remission after a prolonged course of systemic therapy with low doses of isotretinoin. Cumulative dose of isotretinoin for persistent clinical remission was 46.4 mg/kg of weight, 17.6 mg/kg, 12.6 mg/kg respectively. Difficulties related to the subjective perception of patients of his condition has limited the possibility of increasing daily dose of isotretinoin, and the lack of result from the previous therapy with basic medications has made isotretinoin a drug of choice.

Objective. To assess clinical and morphological changes in the skin in patients with severe to moderate acne in the course of systemic treatment with isotretinoin in the form of LlDoSE. Materials and methods. The authors conducted a study of the clinical and morphologic state of the skin in 40 patients with severe to moderate acne, who were administered the treatment with systemic retinoids. Previous external therapy was inefficient in 70% of the patients. As many as 45% of the patients developed scars as a result of the regression of acne vulgaris. To visualize the structure of the epidermis, derma and subcutaneous layer, the authors used the ultrasonic skin scanning method at the frequency of 75 M. Results. The skin scanning images obtained as a result demonstrated the possibility of visualizing inflammatory components in the derma, differences in the skin density indices in different facial zones prior to the therapy and reduction in these indices against the background of the systemic therapy with isotretinoin by the third month of the treatment.

Objective. To analyze the clinical and morphological changes in the skin in case of inflammatory dermatoses when Aisida, a cream gel for dry and sensitive facial and body skin, is used as a monotherapy. Materials and methods. Aisida, a cream gel for dry and sensitive facial and body skin with the ASD concentration of 0.05%, was used as the first-line treatment for dermatoses in 72 patients with dry skin as the key factor of dermatosis pathogenesis (atopic dermatitis, eczema against the background of xerosis, retinoid dermatitis against the background of a system therapy with isotretinoin). In order to visualize the structure of epidermis, derma and hypoderm, the authors used the ultrasonic skin scanning method at the frequency of 75 M Results. The authors demonstrated high clinical efficiency of the drug. Skin scanning images confirmed the evident effect of the Aisida cream gel on the dermal acoustic density.

According to the results of a study that involved 32 psoriatic patients, nevi with the diameter exceeding 5 mm are found in 68.8% of patients including 36% of patients with iatrogenic melanoma development risk factors (treatment with methotrexate and phototherapy), 50% of patients with anamnestic (burn injuries including vesication at the age below 18) and 4.5% of patients with inherited risk factors (melanoma in their relatives). As many as 32.4% of the nevi met the dysplastic nevi criteria in the course of the Pehamberger model analysis.

The goal was to determine clinical and anamnestic features of acne patients aged up to 18 years needing systemic isotretinoin treatment, and to assess the treatment dynamics. Materials and methods. The authors conducted a study of 27 patients with moderate to severe acne (with the mean age of 16.2 ± 1.2 years) receiving isotretinoin in the form of LIDOSE (Acnecutan) in the dose of 0.33 ± 0.06 mg/kg. Results. A steady improvement of the skin condition was observed when the dose of isotretinoin in the form of LIDOSE of 60.3 ± 2.8 mg/kg was used. Clinical recovery was observed in all of the patients (the cumulative dose amounted to 100 mg/kg). Teenagers demonstrated good tolerance to the drug and had no systemic adverse effects.
