Research objective: to evaluate the clinical efficacy of vaginal gel with hyaluronic acid Revitaxa gel in comparison with synthetic estrogen-like topical agent in the treatment of women with genitourinary syndrome, to determine the recurrence rate of atrophic changes as a result of these schemes.Materials and methods. The study included 60 women with genitourinary manifestations and atrophic changes of the vaginal mucosa and cervical epithelium. Clinical, cytological and colposcopic studies were performed to analyze the vaginal epithelium, vaginal microbiocenosis and vaginal tissues. All women with an inflammatory type of smear were prescribed vaginal rehabilitation before the study. Repeated laboratory examination after anti-inflammatory, antibacterial topical therapy confirmed no pathogenic microflora, but signs of atrophy persisted in all women. All women are prescribed local treatment to improve the reparative processes of the vaginal mucosa. The main group (30 women) used Revitaxa gel for local therapy; the control group (30 women) used vaginal suppositories with the synthetic estrogen-like agent promestrienum.Results. Cytological remission after treatment was observed in all women of the control group and in 76.7% of patients in the main group. Restoration of the vaginal mucosa was detected in all patients of the control group and in 90% of patients in the main group. Repeated examinations 4 months after the end of therapy determined no recurrence of atrophic colpitis in 53.3% of patients in the main group and in 30% of women in the control group. Preservation of a favorable estatrophic type of smears was observed in 43.3% of women of group I and 13.3% of patients of group II (p <0.05), which indicates a more stable effect of hyaluronic acid compared with estrogen-like agent.Conclusions. Vaginal gel with hyaluronic acid Revitaxa gel in women with genitourinary syndrome gives results similar to the synthetic estrogen-like drug with promestrienum for topical treatment according to colposcopy, cytology, hormonal colpocytology and clinical indicators. Therefore, Revitaxa gel may be recommended for effective use in women with atrophic colpitis who refuse or have contraindications for topical hormonal agents.

Цель исследования. Разработка методов сопроводительной терапии для защиты нормальных органов и тканей, входящих в зону облучения. Методы. В исследование включено 112 больных раком шейки и тела матки после комбинированного или самостоятельного лучевого лечения с 2012 по 2016 гг. У 71 пациентки основной группы в качестве терапии сопровождения применяли гидрогель с деринатом и у 41 больной группы контроля - традиционные методы профилактики (масло оливковое, подсолнечное, метилурациловая мазь). Для профилактики эпителиита слизистой влагалища и шейки матки в основной группе использовали гидрогель в виде аппликаций с первого дня облучения. Для профилактики лучевого ректита гидрогель вводили в прямую кишку 1 раз в день с первого дня облучения. Инстилляции гидрогеля в мочевой пузырь начинали только при развитии первых признаков клинической картины цистита. Пациенткам контрольной группы для профилактики лучевых реакций проводились масляные, мазевые аппликации во влагалище, масляные микроклизмы в прямую кишку с первого дня облучения. Лечение лучевого цистита проводили с помощью растительных диуретиков, уросептиков. Результаты. Применение гидрогеля с деринатом позволило провести курс лучевой терапии без перерыва у 84,5% (60/71) больных, в контрольной группе - лишь у 48,8% (20/41). Лучевые циститы возникали в 2,5 раза реже (25,3% ± 3,3 против 63,4% ± 2,7, р<0,01). Анализ степени выраженности лучевого цистита по RTOG в двух группах показал, что у 75% больных основной группы наблюдалась I степень, у 25% - II степень, III и IV степени не отмечено, тогда как в контрольной группе лучевой цистит I степени развился у 44% пациенток, II - 40% и III - 16% больных. Применение гидрогеля снизило частоту лучевых ректитов в 2 раза (26,7% ± 3,3 против 53,7% ± 3,2 р<0,1).При использовании ежедневных аппликаций гидрогеля с деринатом со стороны слизистой оболочки влагалища и шейки матки преобладали эпителииты I степени (53,5%), II степень наблюдалась у 29,5% и III степень лучевой реакции - лишь в 16,9% случаев, IV степень реакции не отмечена. В контрольной группе эти показатели составили 26,8%, 24,3%, 31,7% и 17,2% соответственно. Разработаны цитологические критерии оценки течения лучевых реакций слизистой влагалища. Выделены три степени изменения цитограммы, которые коррелировали с клинической картиной. В основной группе лучевые изменения I степени зафиксированы в 4,5 раза чаще (52 ± 9,9% против 11,5 ± 6,3%, р<0,002), а III степень представлена в 3,8 раза реже, чем в контрольной группе (12 ± 6,5% против 46,1 ± 9,8%, р<0,003). Заключение. Применение гидрогелевого материала с деринатом в качестве препарата сопроводительной терапии во время курса облучения позволяет уменьшить частоту и степень выраженности лучевых повреждений со стороны слизистой влагалища, мочевого пузыря и прямой кишки, провести курс лучевой терапии без перерыва и улучшить качество жизни пациенток. Objective. Development of methods for accompanying therapy to protect normal organs and tissues in the irradiation zone. Method. The study included 112 patients with cervical and endometrial cancer after combined or independent radiotherapy from 2012 to 2016. In 71 female patients of the main group, Derinat with hydrogel was applied as a supportive therapy and in 41 patients of the control group, conventional prevention methods (olive oil, sunflower oil, methyluracyl ointment) were applied. For prevention of vaginal mucosal and cervical epitheliitis in the main group, hydrogel was used as applications from the first radiation day. For prevention of radiation proctitis, hydrogel was injected into the rectum once daily from the first radiation day. Hydrogel instillations into the bladder were started only with the first clinical signs of cystitis. For prevention of radiation reactions, vaginal oil and ointment and rectal oil micro-enema were administered to patients of the control group from the first day of irradiation. Radiation cystitis was treated with vegetable diuretics and uroseptic drugs. Results. Using the hydrogel with Derinat allowed to administer a course of radiotherapy without interruption in 84.5% (60/71) of patients and only in 48.8% (20/41) in the control group. Radiation cystitis occurred 60% less frequently (25.3% ± 3.3 versus 63.4% ± 2.7, p <0.01). Analysis of radiation cystitis severity in two groups (according to RTOG) showed that 75% of patients in the main group had grade I and 25% had grade II. Grade III and grade IV did not occur. At the same time, in the control group, grade I radiation cystitis developed in 44% of patients, grade II - in 40%, and grade III - in 16% of patients. The hydrogel treatment halved the frequency of radiation proctitis (26.7% ± 3.3 vs. 53.7% ± 3.2 p <0.1). With daily application of the hydrogel with Derinat, grade I epitheliitis (53.5%) predominated in vaginal and cervical mucosa, grade II was observed in 29.5%, and grade III radiation reaction - only in 16.9% of cases; grade IV reaction was not observed. In the control group, these proportions were 26.8%, 24.3%, 31.7%, and 17.2%, respectively. Cytological criteria were developed to evaluate the course of radiation reactions in the vaginal mucosa. Three degrees of change in the cytogram were identified, which correlated with clinical picture. In the main group, incidence of grade I radiation-induced changes was increased by more than 350% (52 ± 9.9% vs. 11.5 ± 6.3%, p <0.002), and incidence of grade III was decreased by more than 70% compared to the control group (12 ± 6.5% vs. 46.1 ± 9.8%, p <0.003). Conclusion. Using the hydrogel material with Derinat as an accompanying therapy during the course of irradiation allows to reduce frequency and severity of radiation injuries of the vaginal mucosa, bladder, and rectum, administer an uninterrupted course of radiotherapy, and improve the quality of life of patients.

Treatment of tracheal stenosis is occasionally performed in combination with wound healing modulators to manipulate new extracellular matrix (ECM) formation and prevent fibrosis. Hyaluronic acid (HA) and collagen-polyvinylpyrrolidone (collagen-PVP) decrease fibrosis in experimental tracheal healing. However, they have not been used clinically as their effect on ECM components, which modify tracheal scarring, has not been described. Objective. To evaluate the effect of the application of HA, collagen-PVP, a mixture of HA and collagen-PVP (HA+collagen-PVP), and mitomycin C on the expression of decorin, matrix metalloproteinase 1 (MMP1), and MMP9, as well as the type of collagen and deposits formed in the scar after resection and end-to-end anastomosis (REEA) of the cervical trachea using an experimental model. Materials and Methods. Thirty dogs underwent REEA of the cervical trachea and were treated with different wound healing modulators: group I (n=6), control; group II (n=6), HA; group III (n=6), collagen-PVP; group IV (n=6), HA+collagen-PVP; and group V (n=6), mitomycin C. The dogs were evaluated clinically and endoscopically for 4 weeks. Subsequently, macroscopic and microscopic changes, expression of ECM proteins, and collagen deposition in tracheal scars were analysed. Results. Groups II, III, and IV showed reduced endoscopic, macroscopic, and microscopic inflammation, improved neovascularization, high decorin expression (p<0.01, analysis of variance (ANOVA)), and moderate expression of MMP1 (p<0.003, ANOVA) and type I and III collagen (p<0.05, Kruskal–Wallis). Groups IV and V developed fewer collagen deposits (p<0.001, ANOVA). Conclusion. Treatment with HA and collagen-PVP improved post-REEA healing by increasing neovascularization, stimulating the expression of decorin, and regulating the expression of MMP1, as well as type I and III collagen and their deposition.

Objective: To study the features of clinical manifestations, cellular and humoral immunity of newborns with intrauterine mixed infections (IUMI). Methods: A comprehensive survey of 45 infants with IUMI was carried out. Depending on the classification of IUMI they were divided into 3 main groups: group I – 24 patients (53%) with the viral-bacterial association, group II – 12 patients (27%) with the viral-viral association, and group III – 9 patients (20%) with the viral-parasitic association. The control group consisted of 10 newborns born from uninfected, somatically healthy mothers. Diagnosis of IUMI was based on the detection of specific antibodies of the IgA, IgG and IgM classes, as well as phagocytic activity and phagocytic index of leukocytes. In addition, general clinical, biochemical, bacteriological and instrumental research methods have been conducted. Results: The blood serum IgA and IgM indices in patients of the main group were significantly higher, and the mean IgG values were lower compared to the control group. Analysis of cellular immunity parameters in the main group showed a decrease in the number of mature T-lymphocytes (CD3), B-lymphocytes (CD20), the number of T-helpers and cells that produce IL-2 in the peripheral blood, compared with the control group. In the main group, there was also an increase in the number of apoptosis cells (CD95), cells with high cytotoxic activity (CD25, CD71) and the percentage of natural killer cells (CD16). A decrease in the phagocytic activity and phagocytic index of neutrophils was recorded, which indicates the insufficiency of the nonspecific component of immunity. Conclusions: In newborns, various changes were found both on the part of specific and nonspecific components of immunity. This indicates the development of secondary immunodeficiency in this category of patients and makes it necessary to add to the main treatment of immune corrective therapy. Keywords: Congenital infections, mixed intrauterine infections, TORCH syndrome, opportunistic infections, secondary immunodeficiency.

Vaginal dryness is a common condition that is particularly prevalent during and after the menopause and it is one of the most important symptoms associated with vulvovaginal atrophy/genitourinary syndrome of menopause. The impact of vaginal dryness on interpersonal relationships, quality of life, daily activities, and sexual function can be significant, but is frequently underreported and undertreated. Personal lubricants and moisturizers are effective at relieving discomfort and pain during sexual intercourse for women with mild to moderate vaginal dryness, particularly those who have a genuine contraindication to estrogen, or who choose not to use estrogen. We evaluated the safety and beneficial effects of a new type of estrogen-free vaginal gel, Feminilove BIO-FRESH moisturizing vaginal gel, using in vitro and in vivo experimental tools. Our results suggest that; 1) Feminilove vaginal gel exhibits minimal cell cytotoxicity on various human vaginal cells; 2) Feminilove vaginal gel exhibits minimal side-effects on the structure of vaginal mucosa stratum of experimental animals; 3) Feminiove vaginal gel inhibits the growth of pathogenic vaginal bacteria (E. coli) while promotes the growth of beneficial vaginal bacteria (Lactobacillus spp); 4) Feminilove vaginal gel elicits an anti-inflammatory response on vaginal epithelial cells; and 5) Feminilove vaginal gel promotes the production of tropoelastin and collagen on cultural vaginal smooth muscle and may restore loose vaginal wall (i.e., tightening effects). In summary, our results indicate that Feminilove BIO-FRESH moisturizing vaginal gel is a safe and effective remedy for the treatment of symptoms associated with vaginal dryness and vulvovaginal atrophy in women.

Treatment of trophic ulcers of lower extremities is one of the most important problems of surgery. The aim of the study is to determine the features of the microbial landscape of trophic ulcers in various methods of local treatment. The results of studies on the microflora of trophic ulcers of lower extremities in 245 patients of the main and control groups were analyzed. In 96 patients with trophic ulcers (the main group), Miliacil and magnetolaser therapy were used locally in the treatment of trophic ulcers. For the treatment of 60 patients of the first control group with trophic ulcers, Miliacil and laser radiation were applied topically. In the second control group (59 patients), only Miliacil was used. In the third control group (30 patients), 1% dioxidine solution was used topically for the first 7–10 days, and then the treatment was followed by applying the sea buckthorn oil. The microbiological studies of the trophic ulcer contents demonstrated that Miliacil in combination with laser radiation and especially in combination with magnetic laser therapy had a more pronounced antimicrobial effect than only miliacil and even more so than the 1% dioxidine solution and sea buckthorn oil. It was found that in 161 (65.7%) patients the pathogens were inoculated in the form of a monoculture and in 84 (34.3%) - in the form of microbial associations. According to the composition of strains, among monocultures, 67 (41.6%) patients had Staphylococcus aureus, 39 (24.2%) - Proteus, 24 (14.9%) - E. coli, 20 (12.4%) - Pseudomonas aeruginosa and 11 (6.9%) -Streptococcus. The Staphylococcal associations were predominant, they were found in 68 (80.9%) patients. 336 strains of microorganisms were isolated and 296 (88%) of them were resistant to three or more antibiotics. At the end of treatment, in 87 (90.6%) patients of the main group, there was not observed any microflora in the ulcer inoculations. At the end of treatment, the ulcer microflora was not observed in 51 (85%) patients in the first control group, in 36 (61%) patients in the second control group, and in seven (23.3%) patients in the third control group. Thus, as result of studies conducted the specific features of the microbial landscape of trophic ulcers with different methods of topical treatment have been established.

The article presents the results of treatment of patients with acute inflammatory diseases of the maxillofacial region using non-drug methods of treatment. Study material: 60 patients with acute purulent-inflammatory diseases of the maxillofacial region (phlegmons and abscesses), who were divided into 2 groups: the main group — 30 patients who underwent a course of complex application of broadband electromagnetic therapy and low — frequency alternating electrostatic field and the control group — 30 patients who were treated with drug therapy (antibiotics, metronidazole group drugs, antihistamines, multivitamins, detoxification therapy, local treatment of the wound process), which served as the background in the main group. Objective: to develop and scientifically substantiate the complex application of broadband electromagnetic therapy and low-frequency alternating electrostatic field in patients with inflammatory diseases of the maxillofacial region. Results. In a comparative aspect, the dynamics of the indicators of the leukocyte intoxication index (LII) and the main indicators of the morphological picture of the blood before and after treatment in patients with HIA CHLO under the influence of the developed complex was studied. Conclusion. The developed complex, which includes a low-frequency alternating electrostatic field and broadband electromagnetic therapy, contributes to the formation of pronounced anti-inflammatory and detoxifying effects in patients with inflammatory diseases of the maxillofacial region due to a significant reduction in endogenous intoxication, which allows us to recommend it for inclusion in complex therapeutic and rehabilitation programs after surgical interventions to accelerate the time of purulent wound cleansing and reduce the length of hospital stay.

Introduction/Aim. Gingivitis is a common occurrence in children and may well be thought as a risk factor for the appearance and progression of the diseases of parodontal tissues. It is thus necessary to react in a timely and adequate fashion to prevent the disease to become serious and produce parodontopathy. The aim of the study was to establish the efficacy of hyaluronic acid in the treatment of chronic gingivitis in children. Methods. The study enrolled 130 children with permanent dentition. All of the examinees were divided into three groups: group I - 50 patients with chronic gingivitis in which only the basic treatment was applied; group II - 50 patients with chronic gingivitis in which hyaluronic acid was applied in addition to basic treatment; group III - 30 examinees with healthy gingiva (control group). Assessment of oral hygiene and status of the gingiva and parodontium was done using the appropriate indexes before and after the treatment. Inflammation of the gingiva was monitored by way of cytomorphometric studies. Results. The pretreatment values of the plaque index (PI) were high: in the group I PI was 1.94; in the group II PI was 1.68. After the treatment, the PI value was reduced to null in both groups (PI = 0). In the group III PI was 0.17. The bleeding index (BI) in the group I was 2.02 before and 0.32 after the treatment; the BI value in the group II was 1.74 before and 0.16 after the treatment. In the group III BI was 0. In the group I, the Community Periodontal Index of Treatment Needs (CPITN) was 1.66 before and 0.32 after the treatment; in the group II, the CPITN value was 1.5 before and 0.24 after the treatment. In the group III, the CPITN value was 0. In the group I, the size of the nuclei of the stratified squamous epithelium of the gingiva was reduced, although not so much as the nuclear size in the group II of examinees. Conclusion. Basic treatment is able to successfully treat chronic gingivitis in children. The use of hyaluronic acid together with the basic treatment can markedly improve the treatment effect.

The aim of the study was to determine the maternal factors of perinatal complications in women with diseases of the urinary system. A group of women with pathology of the urinary system were studied during the course and completion of pregnancy. The complications in childbirth condition of newborns in comparison with similar indicators in healthy women were also assessed. It was found that most women with urinary tract pathology that were pregnant again, had complications of somatic (most often a combination of urinary tract pathology and chronic infectious diseases) and reproductive history (most often – miscarriages). Women with complications during pregnancy, pyelonephritis, anemia, and the threat of abortion were significantly more often registered in the main group (p<0.05). Women in the main group were significantly more likely to have premature births: 15.4% of women with acute pyelonephritis and 46.2% of women with chronic pyelonephritis, while all women in the control group gave birth on time (P<0.05). Significantly more women in the main group had complications in childbirth: most often – weakness of labor – I group 8 (6.2%), II – 9 (6.9%). Termination of pregnancy in the vast majority of women in the main group was physiological, cesarean delivery was completed in 3 (2.3%) women in group I and 10 (7.7%) women in group II. All women in the control group had timely, physiological births. The condition of newborns of mothers with pathology of the urinary system was often disturbed. A significant proportion of children from the main group (I – 5.4%, II – 10.0%) required immediate resuscitation measures at birth and their transfer to specialized departments for further treatment.

Study Objective: To optimize pregnancy management and improve delivery outcomes in women with infertility of endocrine origin after the use of assisted reproductive technologies (ART). Study Design: This was an analytical prospective study. Materials and Methods: One hundred and twenty patients with singleton pregnancy were observed: 74 women with infertility of endocrine origin who had undergone in vitro fertilization (IVF) (Group I) and 46 women who became pregnant spontaneously (Group II). The main group (Group I) was divided into subgroup IA (n = 44), in which a comprehensive approach to pregnancy was applied (obstetric pessary and micronized progesterone), and subgroup IB (n = 30) consisting of patients for whom micronized progesterone alone was used. Study Results: Groups I and II differed significantly in miscarriage risk rates: 60.8% and 30.4%, respectively. This complication was most often observed in subgroup IB (80.0%), 2.6 times more often than in Group II (χ2 = 5.700; p = 0,029). There were also statistically significant differences between the groups in the rate of preterm delivery (PD), which was 5.6 times higher in the main group than in the control group (24.3% vs. 4.3%, χ2 = 4.915; p = 0.027). The greatest difference from the control group (9.3 times higher rate) was observed in subgroup IB (χ2 = 10.156; p = 0.004). Conclusion: A comprehensive approach makes it possible to prolong pregnancy, reduce rates of PD by a factor of 2.9 and achieve full-term pregnancies in 86.4% of cases. Keywords: pregnancy, IVF, ART, obstetric complications, perinatal outcomes, Arabin pessary.
