Physiological cervical ectopy (CE) is commonly found in young women, during pregnancy or intake of oral contraceptives. The complicated (pathological) CE, particularly in conditions of vaginal microbiota disturbances and human papillomavirus (HPV) infection, requires intervention, including optimal treatment and effective relapse prevention approaches. Aim. The aim of the research was to investigate the complicated CE clinical course and recurrence features on the basis of a retrospective analysis of archival medical records in order to optimize the tactics of the complicated CE management and the relapse prevention measures. Materials and methods. In the observational cross-sectional retrospective study using the continuous sampling method were included 740 case reports of women, who underwent inpatient treatment of gynecological pathology in Lviv Municipal Clinical First Aid Hospital in 2006–2017. The inclusion criterion was the presence of firstly diagnosed or recurrent CE. Exclusion criteria: absence of CE colposcopic or morphological confirmation, presence of physiological CE (on conditions of cytological, bacterioscopical, bacteriological and colposcopical abnormalities absence). Subsequently, three groups were formed: control group (n=150) – healthy women, who applied for a regular gynecological examination; group 1 (n=483) – women with firstly diagnosed CE; group 2 (n=257) – women with recurrent CE. Differences in mean values were considered significant with a probability level of at least 95 % (p<0.05). Results. Patients with recurrent CE had more pregnancies (p<0.05) than the ones with firstly diagnosed CE and women of control group. The proportion of women with high parity in group 1 and group 2 was three times higher (p<0.05), than in group 3. The proportion of artificial abortions in patients of groups 1 and 2 was more than two times higher (p<0.05), than in women in the control group, group 2 patients had more miscarriages and missed miscarriages(p<0.05) in comparison to the control group. Menarche in patients with recurrent CE set in later in comparison to women of control group (p<0.05). In group 2, the proportion of women with polymenorrhea was three times higher (p<0.05), than in group 1 and control group respectively. The compromised gynecological history was more often (p<0.05) detected in group 1 and group 2, than in the control group. In patients with recurrent CE a third of gynecologic diseases in the history (32.30±2.92 %) and 23.60±1.93 % - in patients with the firstly diagnosed CE were pelvic inflammatory diseases, significantly (p<0.05) higher in comparison to the control group (3.33±1.47 %). Almost half of patients in group 1 (48.25±2.27 %) and group 2 (47.84±3.13 %) had the history of frequent infectious diseases, this indicator was significantly (p<0.05) higher in comparison to the control group (24.67±3.52 %). In patients with recurrent CE chronic diseases of different etiology were diagnosed more often (p<0.05) - their share made up 8.24±1.72 %, while in patients with firstly diagnosed CE - 4.33±0.92 %, in women of the control group - 1.33±0.94 %.The firstly diagnosed CE was more frequent (in comparison to recurrent CE) (p<0.001) characterized by asymptomatic course, whereas about half of patients with recurrent CE (46.69±3.11 %) presented with different complaints. Cytological indicators of cervicitis were found more often in patients with firstly diagnosed and recurrent CE, than in women of control group, as well as vaginal candidosis (p<0.05). Patients with recurrent CE more often (p<0.05) underwent diathermoconization (24.12±2.67 %) and cryodestruction of the cervix (8.17±1.71 %) in comparison to patients of group 1. The most often performed treatment method in patients of both groups was diathermoconization. Treatment methods aimed to restore the hormonal balance, to normalize the state of vaginal microbiota were rarely found in both group 1 and 2, drugs that affect the reparation and regeneration of the epithelium have not been used in any case. Conclusions. Recurrent symptomatic complicated CE should be interpreted as a complex problem that requires a multi-polar approach aimed at hormonal homeostasis, local immunity, and vaginal biocenosis normalizing. These measures should precede invasive treatment and further create optimal conditions for regeneration of the cervix.

Cervical ectopy is one of the most common benign processes, characterized by relatively high recurrence rate, and in the case of vaginal microbiota violations in the conditions of HPV infection combination deserves the aimed attention, particularly in the context of reproductive health care and cancer prevention. The objective: to study the vaginal microbiota features in patients withcervical ectopy relapsein the conditions of HPV infection. Materials and methods. The study included 98 women of reproductive age (18 to 46 years). Three groups were formed: a control group (n=30), in which conditionally healthy women were included, group 1 (n=33) – patients with firstly diagnosed cervical ectopy, group 2 (n=35) – patients with cervical ectopy relapse. All women wereexamined with a bacterioscopic, cytological, microbiological study of the vaginal biocenosis, as well as a determination of the vaginal environmentpH level. Results. In patients with cervical ectopy relapse the pH of the vaginal environmentwas significantly higher than that in women of the control group (p<0.001) and of the group 1 patients (p<0.05). About 9% of patients in both study groups had signs of bacterial vaginosis; in about 70% of group 2 patients the signs of mild and moderate severity aerobic vaginitis were found, significantly (p<0.05) more often than in patients with firstly diagnosed cervical ectopy. In group 2 patients a significant polymorphism of infects was detected in 40.00±8.28% of cases, the associations of 3 or more microorganisms determined simultaneously were significantly (p<0.001) more often foundin group 2 in comparison with patients with firstly diagnosed cervical ectopy. Сonclusion. The use of the short-term test system A.F.GENITAL SYSTEM (Liofilchem®, Italy) has a number of advantages for clinical practice: results being ready in short time, the detection of a wide range of infections, the possibility of quantifying M. hominis and U. urealyticum, and then determining the sensitivity to the most frequently used antibacterial drugs. Recurrent cervical ectopy often occurs in the conditions of colpitis, vaginitis, vaginal microbiota disorders with significant polymorphism of microorganisms and alkalization of the vaginal environment, which complicates the processes of ectopy epithelialization and can predispose to its recurrence. The observed cytological features in this cohort of patients suggest that long-term violations of the vaginal biocenosis in combination with the inflammatory processes of the vagina and cervix create favorable conditions for the realization of dysplastic changes caused by HPV. When determining the tactics of treatment of recurrent cervical ectopy, in particular in the conditions of HPV infection, first of all it is necessary to achieve both the cytological norm and the normalization of the vaginal biocenosis before any intervention, if necessary. Key words: relapse of cervical ectopy, vaginal biocenosis, vaginitis, cervicitis, HPV.

According to WHO data, nowadays at least 2.2 billion people worldwide currently have visual impairment or blindness, of which more than 11.9 million people worldwide have moderate to severe irreversible visual impairment that could be prevented. Objective: to assess the clinical course of a standard infected corneal burn during treatment using combined ophthalmic medicinal films levofloxacin + dexpanthenol and dexamethasone + dexpanthenol from a comparative perspective. Materials and methods. The article investigates the pharmacological activity of five different drug regimens for the treatment of an infected corneal burn in rabbits. Treatment of the first wave began 1 hour after the formation of a standard infected corneal burn. Treatment of the second wave began after the absence of signs of an inflammatory reaction was detected. The clinical course of the standard infected corneal burn was assessed immediately after the formation of the burn and the infection, 1 hour, 2, 3, 5 and 14 days after the experiment started. Results. Clinical recovery began on the 3rd day in experimental group 2 treated with combined ophthalmic medicinal films of levofloxacin 1.5 mg + dexpanthenol 1 p/day. On the 5th day of the experiment, recovery was recorded in the experimental group 1 treated with 1.5 mg levofloxacin-based eye films once a day, as well as in comparison group 2 treated with 0.5% levofloxacin 4 times a day and 5% dexpanthenol 6 times a day. On the 7th day after the formation of a standard infected corneal burn, clinical recovery was recorded in comparison group 1 treated with instillations of levofloxacin 0.5% 4 times a day. In the control group with placebo treatment no conjunctiva inflammatory reaction was recorded on the 14th day of the experiment, however, there was persistent corneal opacity in the form of a spot at the burn site. Conclusions. While treating a standard infected corneal burn, the use of combined ophthalmic medicinal films can shorten the clinical recovery period to 3 days, in comparison with treatment with instillations, where recovery occurred on the 5th day of the experiment.

The present study aimed to investigate the prophylactic effect of Cymbopogon proximus and Alhagi maurorum on Sulfadimidine induced urolithiasis in rabbits . Thirty New Zealand male rabbits were allocated into six equal groups (each of five): Group (1) was used as a negative control. Group(2) were administered sulfadimidine (200mg/kg) by intramuscular injection.Groups(3) and (4) were administered sulfadimidine(200mg/kg) by intramuscular injection and 330mg/kg of Cymbopogon proximus alcoholic and aqueous extracts respectively orally.Groups(5) and (6) were administered sulfadimidine(200mg/kg) by intramuscular injection and 400mg/kg of Alhagi maurorum alcoholic and aqueous extracts respectively orally. The period of experiment was 10 days. Blood and urine samples were collected from rabbits on the 10th day. The results recorded a significant decrease in serum creatinine, urea, uric acid and crystalluria in Cymbopogon proximus and Alhagi maurorum groups compared to sulfadimidine treated group.We conclude that Cymbopogon proximus and Alhagi maurorum have a nephroprotective and antiurolithiatic effects against sulfadimidine induced crystalluria.

Introduction: Removable dentures are used by 20% of the population. These may be accompanied by denture stomatitis in 15-70% of patients. The choice of the optimal cleansing agent for removable dental prostheses is of high significance. Aim: The aim of our research was to study the influence of removable denture cleansing products on the adhesion of microorganisms and yeast. Materials and Methods: We manufactured 144 specimens of standardized round shape with a diameter of 10 mm from 4 types of modern polymeric materials used by prosthetic dentistry to produce removable dentures, 12 specimens of each material were placed into suspensions of bacterial cultures of Staphylococcus aureus, Escherichia coli, Candida albicans, then into “ClearaSept” (Test group 1), “Рrotefix active cleanser” (Test group 2), saline solution (Control group), followed by nutrient media. The adhesion index was calculated and analyzed. Results: There was no reliable lowering of adhesion index of Staphylococcus Aureus to all materials detected in Test group 1 (U=6, p>0.05 for Bio XS; U=8, p>0.05 for Dental D, Denotokeep Peek, Vertex Rapid Simplified). In Test group 2, the adhesion index of Staphylococcus Aureus reliably decreased to all materials compared to the Control group (U=0, p≤0.01). The adhesion index of Candida albicans and Escherichia coli to all materials in Test group 1 had a minor to moderate reliable reduction compared to the Control group (U=0, p≤0.01). Test group 2 showed a significant reliable decrease in Candida albicans and Escherichia coli adhesion index to all materials in comparison with the Control group (U=0, p≤0.01). Conclusion: The research showed an unreliable or minor and moderate reliable decrease in microorganisms adhesion index depending on the microorganism species after treatment of denture material specimens by antibacterial soap “ClearaSept” and a reliable significant decrease in microbial and yeast adhesion after application of Protefix active cleaner solution, which demonstrates a more significant antimicrobial effect in comparison to “ClearaSept” against Staphylococcus aureus, Escherichia coli, and Candida albicans.

Effects of a dopamine-1 (DA-1) receptor agonist on systemic and intestinal oxygen delivery (D˙o 2)-uptake relationships were studied in anesthetized dogs during sequential hemorrhage. Control ( group 1) and experimental animals ( group 2) were treated similarly except for the addition of fenoldopam (1.0 μg · kg−1 · min−1) in group 2. Both groups had comparable systemic criticalD˙o 2(D˙o 2crit), but animals in group 2 had a higher gut D˙o 2crit(1.12 ± 1.13 vs. 0.80 ± 0.09 ml · kg−1 · min−1, P < 0.05). At the mucosal level, a clear biphasic delivery-uptake relationship was not observed in group 1; thus oxygen consumption by the mucosa may be supply dependent under physiological conditions. Group 2 demonstrated higher peak mucosal blood flow and lack of supply dependency at higher mucosalD˙o 2 levels. Fenoldopam resulted in a more conspicuous biphasic relationship at the mucosa and a rightward shift of overall splanchnic D˙o 2crit despite increased splanchnic blood flow. These findings suggest that DA-1 receptor stimulation results in increased gut perfusion heterogeneity and maldistribution of perfusion, resulting in increased susceptibility to ischemia.

OBJECTIVE There is no consensus regarding the best surgical strategy at the lumbosacral junction (LSJ) in long constructs for adult spinal deformity (ASD). The use of interbody fusion (IF) has been advocated to increase fusion rates, with additional pelvic fixation (PF) typically recommended. The actual benefit of IF even when extending to the pelvis, however, has not been vigorously analyzed. The goal of this work was to better understand the role of IF, specifically with respect to arthrodesis, when extending long constructs to the ilium. METHODS A systematic review of the PubMed and Cochrane databases was performed to identify the relevant studies in English, addressing the management of LSJ in long constructs (defined as ≥ 5 levels) in ASD. The search terms used were as follows: “Lumbosacral Junction,” “Long Constructs,” “Long Fusion to the Sacrum,” “Sacropelvic Fixation,” “Interbody Fusion,” and “Iliac Screw.” The authors excluded technical notes, case reports, literature reviews, and cadaveric studies; pediatric populations; pathologies different from ASD; studies not using conventional techniques; and studies focused only on alignment of different levels. RESULTS The PRISMA protocol was used. The authors found 12 retrospective clinical studies with a total of 1216 patients who were sorted into 3 different categories: group 1, using PF or not (n = 6); group 2, using PF with or without IF (n = 5); and group 3, from 1 study comparing anterior lumbar interbody fusion versus transforaminal lumbar interbody fusion. Five studies in group 1 and 4 in group 2 had pseudarthrosis rate as primary outcome and were selected for a quantitative analysis. Forest plots were used to display the risk ratio, and funnel plots were used to look at the risk of publication bias. The summary risk ratios were 0.36 (0.23–0.57, p < 0.001) and 1.03 (0.54–1.96, p = 0.94) for the PF and IF, respectively; there is a protective effect of overall pseudarthrosis for using PF in long constructs for ASD surgeries, but not for using IF. CONCLUSIONS The long-held contention that L5/S1 IF is always advantageous in long-construct deformity surgery is not supported by the current literature. Based on the findings from this systematic review and meta-analysis, PF with or without additional L5/S1 interbody grafting demonstrates similar overall construct pseudarthrosis rates. The added risk and costs associated with IF, therefore, should be more closely considered on a case-by-case basis.

Введение. Сосудистые осложнения сахарного диабета (СД) являются одной из ведущих причин повышения смертности пациентов трудоспособного возраста. Предполагается, что индуцированный гипергликемией окислительный стресс и нарушение антиоксидантной защиты играют роль в патологическом механизме повреждения сосудов, частично за счет влияния оксида азота (NО). Цель исследования: уточнение взаимосвязей в системах асимметричного диметиларгинина (АДМА) и NO у пациентов с цереброваскулярными заболеваниями (ЦВЗ) на фоне СД 2-го типа (СД-2). Материалы и методы. Обследованы 72 пациента с ЦВЗ со стенозирующим поражением внутренней сонной артерии вне острого периода: группу 1 составили 39 пациентов (18 мужчин и 21 женщина) с СД-2 в возрасте 65 [58; 72] лет; в группу 2 вошли 33 больных (15 мужчин и 18 женщин) без СД-2 в возрасте 66 [56; 74] лет. Контрольную группу составили 30 добровольцев (16 мужчин и 14 женщин) без проявлений церебральной ишемии и нарушений углеводного обмена, с нормальными значениями индекса массы тела, некурящие, в возрасте 62 [50; 66] лет. Проводилось клиническое обследование, нейро- и ангиовизуализационное исследование, спектр биохимических исследований крови, в том числе определение содержания АДМА и показателей системы NO. Результаты. В группе 1 содержание нитрата, нитрита и NO составило 62,1 [56; 68] мкмоль/л, 48,5 [26; 52] мкмоль/л и 13,6 [9; 23] мкмоль/л соответственно, что достоверно отличалось от значений этих показателей в группе 2 — 58,3 [45; 64] мкмоль/л, 39,6 [26,0; 42,3] мкмоль/л и 18,7 [16,1; 24,7] мкмоль/л соответственно. Отмечен также более высокий уровень AДМА в крови у пациентов с ЦВЗ в сочетании с СД-2 — 0,42 [0,21; 0,53] ммоль/л. Заключение. Обнаружена взаимосвязь между уровнями AДМА и NO при ЦВЗ на фоне СД-2. Это требует продолжения исследований биомаркеров повреждения сосудистой стенки для определения их места в патогенезе ишемических церебральных осложнений СД-2. Background. Vascular complications of diabetes mellitus (DM) are one of the leading causes of increased mortality in patients of employable age. Hyperglycemia-induced oxidative stress and impaired antioxidant protection have been suggested to play a role in the pathological mechanism of vascular damage, in part due to the effects of nitric oxide (NO). Objectives: clarification of relationships in the systems of asymmetric dimethylarginine (ADMA) and NO in patients with cerebrovascular diseases (CVD) and type 2 diabetes (DM-2). Patients/Methods. We examined 72 CVD patients with stenosing lesions of the internal carotid artery outside the acute period: group 1 consisted of 39 patients (18 men and 21 women; 65 [58; 72] years old) with DM-2; group 2 consisted of 33 patients (15 men and 18 women; 66 [56; 74] years old) without DM-2. The control group consisted of 30 volunteers (16 men and 14 women; 62 [50; 66] years old) without manifestations of cerebral ischemia and carbohydrate metabolism disorders, with normal body mass index, non-smokers. A clinical examination, neuro- and angio-imaging study, a spectrum of biochemical blood tests, including the concentration of asymmetric dimethylarginine (ADMA) and indicators of NO system were carried out. Results. In group 1, the content of nitrate, nitrite and NO was 62.1 [56; 68] μmol/l, 48.5 [26; 52] μmol/l and 13.6 [9; 23] μmol/l, respectively, that significantly differed from the content of these parameters in group 2 — 58.3 [45; 64] μmol/l, 39.6 [26.0; 42.3] μmol/l and 18.7 [16.1; 24.7] μmol/l, respectively. Noted also a higher blood level of ADMA in patients with CVD combined with DM-2 — 0.42 [0.21; 0.53] mmol/l. Conclusions. A relationship was found between ADMA and NO levels in CVD patients with DM-2. This requires further studies of biomarkers of vascular wall damage to determine their place in the pathogenesis of ischemic cerebral complications of DM-2.

ObjectivesThe aim of this study was to establish quantitative values for asymptomatic and symptomatic Achilles tendons.DesignCohort study with a single (cross-sectional) time point of patients diagnosed with unilateral Achilles tendinopathy and an asymptomatic group with comparative homogeneity.MethodsA sample of 50 participants: 25 diagnosed with symptomatic unilateral Achilles tendinopathy (AT group) and 25 with asymptomatic Achilles tendons (control group 2). The asymptomatic side of the AT group was used as a control (control group 1). Measurements at 2 cm intervals on the tendon from its insertion at the calcaneum up to the musculotendinous junction were taken non-weight bearing (NWB) and weight bearing (WB) using the MyotonPRO.ResultsThere was a significant (p<0.005) decrease in natural oscillation frequency (F) at points 2, 3 and 4 of the AT group (NWB condition) and points 2 and 3 for the WB condition. There was a significant (p<0.005) increase in logarithmic decrement (D) at points 2 and 3 signifying a decrease in elasticity. Dynamic stiffness (S) was significantly (p<0.005) reduced in the AT group at points 2 and 3 WB and point 3 WB. There was no significant difference in creep (C) observed between the symptomatic and asymptomatic tendons. There was a significant (p<0.005) increase in mechanical stress relaxation time (R) at point 2 NWB.There was a correlation between body weight and gender on tendon mechanics, with the symptomatic tendons. No significant differences were observed between the control group 1 and control group 2.ConclusionsThe MyotonPRO measured decreased stiffness over a section of the tendon corresponding clinically with Achilles tendinopathy. This may have potential in identifying risk of injury and informing rehabilitation, however further extensive research is required to generate baseline data for specific population groups monitoring variables over time. Age, gender and body mass index appear to have some bearing on the mechanical properties of the tendon but mainly in the tendinopathy group.

Purpose To assess efficacy, safety, and changes in higher order aberrations after wavefront-guided photorefractive keratectomy (PRK) in comparison with conventional PRK for low to moderate myopia with myopic astigmatism using a WASCA Workstation with the MEL 70 G-Scan excimer laser. Methods A total of 126 myopic or myopic-astigmatic eyes of 112 patients were included in this retrospective study. Patients were divided into two groups: Group 1, the study group; and Group 2, the control group. Group 1 consisted of 78 eyes treated with wavefront-guided PRK. Group 2 consisted of 48 eyes treated with spherocylindrical conventional PRK. Results Two years postoperatively, in Group 1, 5% of eyes achieved an uncorrected visual acuity (UCVA) of 0.05; 69% achieved a UCVA of 0.00; 18% of eyes experienced enhanced visual acuity of −0.18 and 8% of −0.30. In Group 2, 8% of eyes achieved a UCVA of 0.1; 25% achieved a UCVA of 0.05; and 67% achieved a UCVA of 0.00 according to logMAR calculation method. Total higher-order root-mean square increased by a factor 1.18 for Group 1 and 1.6 for Group 2. There was a significant increase of coma by a factor 1.74 in Group 2 and spherical aberration by a factor 2.09 in Group 1 and 3.56 in Group 2. Conclusions The data support the safety and effectiveness of the wavefront-guided PRK using a WASCA Workstation for correction of low to moderate refractive errors. This method reduced the number of higher order aberrations induced by excimer laser surgery and improved uncorrected and spectacle-corrected visual acuity when compared to conventional PRK.

OBJECTIVE: To evaluate the effects of a 6 month administration of raloxifene hydrochloride, a selective estrogen receptor modulator which was recently approved for the prevention of osteoporosis, on serum gonadotropin and prolactin (PRL) levels and on TRH-stimulated PRL responsiveness in postmenopausal women who have not undergone estrogen replacement therapy. DESIGN AND METHODS: Sixteen healthy postmenopausal women were divided into two groups on the basis of their bone status, evaluated by dual energy X-ray absorptiometry at the lumbar level. Eight women (chronological age 52.4+/-4.1 (s.d.) years, menopausal age 42.4+/-3.9 years), in whom T-score L2-L4 was less than -2.5 s.d., were treated with raloxifene (60 mg p.o.) administered daily for 6 months (group 1), while the other eight women (chronological age 52.6+/-2.5 years, menopausal age 42.1+/-3.6 years), in whom the T-score L2-L4 ranged between -1 and -2.5 s.d., were used as a control group (group 2). Serum PRL, FSH, LH and 17beta-estradiol (E2) levels were evaluated at baseline and after 3 and 6 months of treatment. In all subjects, PRL responsiveness to TRH (200 microg i.v.) administration was evaluated at baseline and at the end of the study. RESULTS: At baseline, mean PRL, LH and FSH levels were not significantly different in the two groups (PRL 133.6+/-21.7 vs 136.7+/-28.1 mIU/l (NS), LH 25.1+/-6.8 vs 24.4+/-6.7 mIU/ml (NS), FSH 74.4+/-25.0 vs 71.1+/-24.1 mIU/ml (NS), in group 1 and group 2 respectively). No significant variations in serum FSH and LH values, in either group, or in serum PRL levels in group 2, were observed at the 3 and 6 month examinations. On the contrary, serum PRL values decreased significantly in group 1 after 3 months (100.1+/-47.7 mIU/l, P<0.05) and 6 months (81.5+/-30.2 mIU/l, P<0.001). At baseline, no significant differences were observed in the TRH-stimulated serum PRL peak between the groups (1015.4+/-30.5 vs 1030.2+/-25.7 mIU/l in group 1 and in group 2 respectively), while it decreased significantly at the 6 month examination in group 1 (770.5+/-47.4 mIU/l, P<0.001) and it was significantly lower than in group 2 (1068.1+/-301.8 mIU/l, P=0.02). Serum E2 was not detected at baseline and at each examination, in all patients. CONCLUSIONS: The decrease of PRL values induced by long-term raloxifene administration in postmenopausal women could be explained by a direct antiestrogenic effect of raloxifene on lactotrope cells or by the recently suggested increase of opiatergic tone on the hypothalamic-pituitary region.
