The results of evaluation of the soft tissue perfusion of the foot in patients with diabetes and critical lower limb ischemia (CLI) via fluorescence angiography (FAG) in the near-infrared range are represented in the article. The study included 4 diabetic patients with CLI. All patients underwent lower-limb balloon percutaneous transluminal angioplasty. To evaluate the soft tissue perfusion of the foot via FAG the following parameters have been used: T0m - time to reach maximum for fluorescence intensity after intravenous administration of Indocyanine green; TIm- time of onset of maximum fluorescence intensity after its appearance in the area of interest; Im - the level of the maximum fluorescence intensity. The region of interest was the skin around the wound of the foot. The median FAG parameters in the region of interest on the foot were as follows: prior to surgery T0m = 164 sec (148–181), TIm = 48 sec (38–56); after surgery: T0m = 80 sec (69–92); TIm = 27 sec (20–39); (p <0,05). No adverse reactions were registered in the study. Despite the small sample we were able to achieve statistical significance in the difference between the parameters prior to and after surgery. Further prospective studies with extended samples of patients are needed.

The short-term and long-term outcomes of treatment in 130 patients with basal cell carcinoma (T1N0M0, I stage) using photodynamic therapy with photosensitizer photolon based on chlorine e6 are represented in the article. The session of photodynamic therapy was performed 2.5-3 h after intravenous injection of photolon at dose of 2-2.5 mg/kg using semiconductor laser (λ=660±5 nm, laser power density — from 0.1 to 0.52 W/cm2, light dose — from 50 to 300 J/cm2). Complete regression of primary and recurrent carcinomas was observed in 90.9% and 88.9% of patients, respectively. For follow-up period of 3 to 76 months the local recurrence of the tumor was in detected in 6.9% of cases. Patients, who followed the light regimen for 2–3 days after photolon administration avoiding direct sun light exposure, had no manifestation of phototoxicity. Ten patients who failed to follow the light regimen had mild hyperemia, itching and burning in the exposed skin area selflimiting in several hours. Cosmetic results of photodynamic therapy with photolon are superior to those for traditional treatment methods for this disease.

The results of multicenter trial for efficacy of fluorescence diagnosis for bladder cancer with agent hexasens (SSC Scientific Research Institute Organic Intermediates and Dyes, Russia) based on hexyl ester of 5-aminolevulinic acid compared with routine cystoscopy are represented in the article. The study included 124 patients. All patients had intravesical instillation of 50 ml of 0,2% hexasens. The exposure time accounted for 1-2 h. After removal of the drug from bladder standard cystoscopy followed by fluorescence diagnosis was performed in every patient. During the local fluorescence spectroscopy the intravesical instillation of the agent hexasens was shown to induce selective accumulation of photoactive protoporphyrin IX in tumor cells comparing with intact bladder mucosa. During 1 h after intravesical instillation of hexasens solution the level of fluorescence of hexasens-induced protoporphyrin IX in the tumor was higher than that in surrounding intact mucosa at average in 5.8 fold. As compared with results of standard cystoscopy, fluorescence diagnosis improved the sensitivity of the method by 24.4% (from 75.6% to 100%), the accuracy – by 15.2% (from 83.3% to 98.5%) and negative predictive value – by 33.5% (from 66.5% to 100%). Fluorescence diagnosis gave an opportunity to detect additional tumor foci, which were invisible in white light, in 27.4% of patients. For fluorescence diagnosis in 4.0% of patients false-positive fluorescence of bladder mucosa was detected that was probably due to inflammation. None of patients received active dose of the drug hexasens had adverse reactions, changes in general well-being and blood and urine parameters. According to the results of the study fluorescence diagnosis with hexasens for bladder cancer is recommended for use in clinical practice.

According to worldwide statistics breast cancer is the most common cancer in women. Despite the success in current methods of treatment post-operative period in major of patients is characterized by post-mastectomy syndrome which leads to impairment in daily activities, difficulties in social adaptation and consequently to dicrease of the quality of life. The specific causes, risk factors, characteristics of clinical and pathogenetic manifestations of post-mastectomy syndrome are described in detail in this review. Different approaches to post-mastectomy syndrome classification, its clinical and instrumental diagnosis are defined. Based on more than 40 publications of Russian and foreign authors, the issue of selection of appropriate treatment tactics for the syndrome is investigated and discussed in detail. A considerable part of the review is focused on the use of physical methods of treating the post-mastectomy syndrome. It is observed that an increasing number of specialists gives preference to methods of conservative treatment special of which are medical gymnastics, complex decongestive therapy and compression therapy. On the other hand, the absence of the unified treatment algorithms is challenging for clinicians. Therefore, its development with the focus on patient-specific approach is a crucial task for modern rehabilitology in breast cancer surgery.

The clinical case of successful use of local fluorescence spectroscopy combined with fluorescence imaging during cystoscopy for diagnosis of recurrent bladder cancer is represented in the article. Histological study of fluorescent foci confirmed tumor growth (urothelial carcinoma) in all areas with high levels of diagnostic parameter. In the fluorescent focus with low diagnostic parameter inflammation was detected.
