Purpose: to compare the effectiveness of laser therapy and traditional methods for managing diabetic patients with purulent-necrotic lesions in their lower extremities.Material and methods. The article presents a retrospective analysis of outcomes after treatment of 76 patients with diabetes mellitus having purulent-necrotic lesions in their lower extremities. Patients were divided into two groups. The first (main) group consisted of 34 patients in whom traditional treatment was accompanied by intravenous laser blood irradiation and local laser therapy; the second (control) group consisted of 42 patients who received only traditional treatment.Results. Laser therapy contributed to more rapid reduction of wound defect (17.4 %) compared to patients after traditional treatment (11.1 %); it reduced the period of transition to inflammatory-regenerative changes, promoted a smaller number of high amputations of lower limbs from 14 to 6 % as well as shortened the length of hospital stay by 11.2 days.Conclusion. Laser light therapy in patients with diabetic foot accelerates cleansing and reduction of the wound area, allows to reduce or eliminate inflammatory process in shorter time than with traditional treatment.

Inflammatory diseases of the mammary ducts are represented by the different nosological forms - periductal mastitis (73.1%) and purulent galactophoritis (26.9%). In view of typical ultrasonic picture in patients with purulent galactophoritis US-assisted mini-invasive retrograde drainage of mammary ducts with aspiration of purulent content through the natural orifice in the nipple is advisable. This method has significant advantages in comparison with traditional surgery and may be recommended for widespread clinical use.

Retrospective analysis of treatment outcomes of 65 patients with purulent-necrotic forms of diabetic foot: group I (35 patients), who received integrated treatment using laser therapy, group II (30 patients), who received traditional treatment. It was established that the use of laser therapy in these patients compared to traditional therapy allows reducing the duration of the inflammatory reaction in tissues (from 6-8 days to 4-5 days), and subsequently to the appearance of granulations on day 7-8 and marginal epithelization by the end of 10 days, which leads to a reduction in the length of treatment.
