Abstract Purpose To quantitatively investigate the role of deep capillary plexus (DCP) in patients affected by type 3 macular neovascularization (MNV), compared to patients with reticular pseudodrusen (RPD) eyes and healthy controls, using optical coherence tomography angiography (OCTA). Methods In this prospective observational study, a total of seventy-eight eyes of 78 patients were included. Group 1 consisted of 40 eyes of 40 patients with stage 1 of type 3 MNV (22 males, 18 females, mean age 73.7, SD ± 6.60) and group 2 included 38 eyes of 38 patients with RPD (17 males, 21 females, mean age 73.2, SD ± 4.55). The control group included 40 eyes of 40 healthy subjects (20 males, 20 females, mean age 71.4, SD ± 6.36 years). We evaluated the retinal vessel density (VD) of superficial capillary plexus (SCP) and deep capillary plexus (DCP) using OCTA. Results Patients with diagnosis of type 3 MNV showed statistically lower values of VD in DCP with respect to controls and to RPD group (p < 0.001), while there were no statistical differences between RPD and control group in macular region. No significant differences in VD of SCP were detected among the three study groups. Conclusion OCTA provides a reproducible, non-invasive detailed quantitative analysis of retinal vascular features and changing in early-stage type 3 MNV patients, which allowed to shed the light on the main role of DCP ischemia in the development of type 3 MNV.

The study values, through electromyography (emg), the stripped urethral sphyncter activity in women with stress incontinence (USI). 10 women with USI and 5 healthy women -control group- underwent urogynecologic examination, urodynamic examination and urethral electromyography examination. The endurance and extension of tension were took in the consideration. 9 women with USI had EGM showing denervation/renervation nervous damage, supported by potential&rsquo;s wideness and length higher than control group (&gt;300&mu;V), either during relax or cough, and the trace&rsquo;s absence of the interference with voluntary contraction. Only one woman with USI showed an EGM compatible with myogen damage: values &lt;100 &mu;V in all traces and negative anamnesis for risk factors. The Authors emphasize the role of EMG as a particular exam to study in deep the causes of urinary incontinence helpful to identify basic disorders of USI.

Aim. To assess the proliferation and dendritic cells markers expression degree at short interference RNA (siRNA) transfection in endometrial cancer associated with experimental thyroid disease. Methods. Experiments were performed on female rats distributed to five groups: I - control group; IIA and IIIА - animals with simulated hypo-and hyperthyroidism and transplanted Guérin’s carcinoma, IIВ and IIIB - animals with simulated hypo- and hyperthyroidism and transplanted Guérin’s carcinoma in combination with siRNA transfection. Orthogonal tumor dimensions were measured starting from the 7-th day after tumor suspension inoculation. Proliferation and dendritic cells markers expression were assessed in tumor samples by immunohistochemistry after the exclusion of animals from the experiment. Results. siRNA inhibitory effect was more marked in animals with hypothyroidism, indicating an important role of thyroid hormones in regulating cell cycle controlling genes expression. Transfection of siRNA increased mature dendritic cells (CD83) expression in tumor tissue in animals with hypothyroidism and increased immature dendritic cells (CD1a) expression in tumor tissue in animals with hyperthyroidism. Conclusion. siRNA transfection inhibits the tumor cells proliferation mainly at hypothyroidism compared to hyperthyroidism.

Background. Endocrine ophthalmopathy (EOP) is an autoimmune orbit disease characterized by soft retrobulbar tissues damage. The level of antibodies to the thyroid-stimulating hormone receptor (TSHRAbs) is considered as a laboratory marker of EOP activity. Interleukins 17 (IL-17) and 23 (IL-23) play an important role in the pathogenesis of some autoimmune diseases and directly correlate with clinical activity. At present, there is an open question about the role of these cytokines in EOP and their relationship with TSHRAbs. Aims. To assess pathogenetic role of IL-17, IL-23 and TSHRAbs in patients with EOP. Materials and methods. The study included 50 people (100 eyes) at the age of 43 [35; 50] years. Three study groups were formed: 32 patients with moderate severity of EOP (clinical group), 18 patients with thyroid pathology without EOP (comparison group) and 15 healthy subjects (control group). All groups were comparable in age and sex. The diagnosis was verified clinically, laboratory and instrumentally. A comprehensive ophthalmologic examination and blood sampling were performed to determine the concentrations of IL-17, IL-23 and TSHRAbs. Statistical processing of the data was carried out in the program “Statistica 10.0”, StatSoft, Inc. Results. An increase in the level of TSHRAbs was observed in all phases of EOP activity in comparison with both comparison group and control (p < 0.05). But in the active phase TSHRAbs level reached the maximum values in 100% of patients. An increase in the IL-17 concentration in 5,3 times was found in the active EOP in comparison with the control group (p < 0.05). Concentration of TSHRAbs and IL-17 in blood serum directly correlates with EOP activity (p < 0.001). After carrying out pulse therapy with glucocorticosteroids, the consentration of IL-17 decreased almost to zero. There were no significant differences in the level of IL-23 in the groups (p = 0.56). Conclusions. Determination of TSHRAbs and IL-17 levels in serum can be used as a laboratory diagnostic marker of EOP activity.

The hyperplastic processes of the endometrium can arise not only against the background of excessive influence of estrogen, but also against the background of epigenetic damages that affect apoptosis, cell proliferation, differentiation, and adhesion, and DNA reparation. The aim of our study was to investigate and analyze the status of methylation of the promoter of SFRP2 gene in patients with hyperplastic processes of the endometrium. Materials and Methods: The study groups were the following: I — patients with endometrial hyperplasia (EH, n = 9); II — patients with endometrial intraepithelial neoplasia (EIN, n = 10), III — control groups: 1) with endometrial cancer (EC, n = 4), and 2) healthy women (n = 4). Determination of promoter methylation of SFRP2 gene was carried out by the semiquantitative method of methylation-specific PCR assay. Results: The maximum level of methylation of SFRP2 gene promoter had been revealed in patients with EC — 42.80 ± 3.55% (р < 0.05). The patients of the I group had the lowest values of methylation of SFRP2 gene promoter — 10.66 ± 0.85%, while in patients of the II group this indicator was higher — 20.60 ± 0.95% (р < 0.05). In healthy women of the control group, methylation of SFRP2 gene promoter was detected in none of the samples. Conclusion: The content of the methylated SFRP2 gene in endometrial tissue of patients with hyperplastic processes higher than 20–25% allows relate these women to the risk group of EC development and dictates the need of intensive observation of such patients.

Key Enzyme

Aromatase is the key enzyme, which converts androgens into estrogens. To study the role of aromatase in pathogenesis of endometriosis 57 patients and 15 healthy women of reproductive age were examined. Aromatase activity was detected by reaction of estrogens on aromatase inhibitor letrozol intake. Ovarian source of detected aromatase activity was proved by suppression of reaction on letrozole intake during therapy with gonadotropin- releasing hormone agonist. Aromatase activity in recalculation on antral follicle in endometriosis patients withII–IV stages was higher than in healthy women, though total ovarian aromatase activity was not differed from control group because of low number of antral follicles in endometriosis patients. The disturbance of folliculogenesis in endometriosis is connected probably with hyperestronaemia, which has ovarian and extragonandal origin.

Background: Biomarkers of resistance to H1-antihistamines (AH) and omalizumab in chronic spontaneous urticaria (CSU) are still a matter of debate. Objective: To identify clinical and laboratory attributes of the patient that may be predictive of AH and omalizumab resistance in CSU. Methods: We conducted a retrospective observational study by using the electronic patient record data base of patients with CSU and of sex- and age-matched controls. Patients with CSU were divided into three study groups: the CSU group, patients who responded to AHs; the antihistamine-resistant CSU (AH-CSU) group, patients refractory to a fourfold AH dose; and the control group, composed of a random sample of age- and sex-matched subjects, with a case-control ratio of 1:2. The patients in the AH-CSU group treated with omalizumab were compared according to the response or resistance to omalizumab. Results: A total of 106 subjects in the AH-CSU group, 483 in the CSU group, and 1198 in the control group were compared. Both AH-CSU (112.7 ± 43.1 kU/mL) and CSU (129.5 ± 52.4 kU/mL) groups were associated with higher plasma total IgE levels than control group (103.2 ± 49.5 kU/mL; p < 0.001). The AH-CSU group was characterized by a higher plasma high-sensitivity C-reactive protein level (6.4 ± 3.7 mg/L) than the CSU group (4.3 ± 1.4 mg/L; p < 0.001) and the control group (3.1 ± 1.8 mg/L; p < 0.001). The AH-CSU and CSU groups were characterized by a lower mean ± standard deviation basophil counts (0.18 ± 0.16 cells ×109/L and 0.19 ± 0.11 cells ×109/L, respectively) than the control group (0.22 ± 0.09 cells ×109/L; p < 0.001). The mean platelet volume was higher in the AH-CSU group (11.2 ± 0.3 fL) than in the CSU group (11.1 ± 0.4 fL; p = 0.002) and in the control group (10.3 ± 0.4 fL; p < 0.001). There were no significant differences in the mean levels of lymphocytes, monocytes, eosinophils, basophils, and platelets, and the rates of eosinopenia and basopenia between the patients in the AH-CSU group who responded to and those who were resistant to omalizumab. Conclusion: This study provided additional data of interest to examine the pathophysiologic role of low-grade inflammation and basopenia in patients with CSU and resistant to AHs and omalizumab.

Cholecalciferol (Vitamin D) is essential to the proper functioning of the human body. This vitamin belongs to fat-soluble vitamins, responsible for stimulating the intestinal absorption of calcium and phosphate. It has been recently observed that vitamin D may be related to cases of female infertility. This study aimed to examine the effect of vitamin D on female infertility by analyzing hormonal and biochemical parameters. Estrogen, progesterone, FSH, LH, total Cholesterol, Triglyceride, HDL, LDL, VLDL, vitamin D, and BMI were tested in 60 women with infertility and 40 fertile women as a control group. The results showed a highly significant elevation in LH concentration, Triglyceride, LDL, and BMI in infertile women, compared to the healthy women at a significant P = 0.025, P = 0.01, P = 0.05, and P = 0.001, respectively. Also, a significant low elevation in the concentration of estrogen, progesterone, FSH, HDL, and vitamin D in infertile women when compared to the healthy women at a significant level of P = 0.01, P = 0.039, P = 0.05, P = 0.05, and P = 0.001, respectively was observed. This vitamin had a strong positive relationship with progesterone, FSH, total cholesterol, HDL, and LDL. It was also proved a significant inverse correlation to LH, estrogen, TG, VLDL, and BMI. It could be concluded that there is a significant decrease in the level of vitamin D in infertile women compared with the group of healthy women, especially with high BMI. It could also be deduced that vitamin D can be a new marker of increasing infertility and miscarriage risk.

Introduction/Objective. Contemporary tendencies suggest that probiotics can significantly reduce the prevalence of caries in children, so it can be considered that they have a positive effect on general and oral health. Lactobacillus rhamnosus GG (LGG) is a probiotic culture of particular importance in preventive dentistry. The aim was to assess the effects of consumption of probiotic strain Lactobacillus rhamnosus GG on the dental plaque accumulation in children with mixed dentition. Methods. Research included 90 children with mixed dentition (5-12 years old). First study group consumed 200 ml of Lactobacillus rhamnosus GG-enriched yogurt (B-Activ LGG, Dukat) daily for a period of 14 days, while the remaining 30 formed the second study group who consumed 200 ml of yogurt (Jogurt 1,5% milk fat, Imlek) with manually added powder from probiotic capsule (Wayaforte LGG capsule, Medis) daily for14 days. The control group consisted of 30 children who had regular diet during examination period. Silness-L?e plaque index and saliva pH (pH-Fix-0-14, Macherey-Nagel) were determined at baseline and also upon intervention completion. Results. An increase in pH values was observed in both study groups. In general sample, there is a significant decrease of mean plaque index values (p ? 0.001). Both study groups had significant decrease of mean plaque index values on the baseline and after 14 days consumption of yogurt. In the control group the number of subjects with decrease plaque index values did not correlate and no association was found. Conclusion. Consistent consumption of LGG culture-enriched yogurt inhibits dental film accumulation and promotes saliva pH increase in children with mixed dentition.

Materials and methods. 28 patients with GE of I-II degrees of prevalence (R-AFS) were included in the study. Control group consisted of 11 healthy women. All the patients underwent laparoscopy and hysteroscopy with histological examination of ovarian tissue, peritoneum and endometrium; patients with GE also were performed histological examination of endometrioid of heterotopies. Definition of levels of kisspeptin, FSH, LH, prolactin, AMH, estradiol, estrone, androgens (free testosterone, dehydroepiandrosterone – DHEA) in peripheral blood in healthy women and in patients with GE were conducted by ELISA on the 2nd and 8th days of menstrual cycle. Immunohistochemical method was used to evaluate expression of metastine (kisspeptin) and its receptor in ovarian tissue, peritoneum, in endometrioid heterotopies and in endometrium. Results. Hormonal survey has revealed that the level of kisspeptin in peripheral blood was reliably higher compared to its level in the control group. Immunohistochemical study found that in patients with GE area of expression of KISS and KISS1R receptor in endometrium was reliably lower when compared with these values in the control group. In the foci of endometrioid heterotopies, which were located on the pelvic peritoneum, it was observed a reliable increase in protein КІЅЅ1 expression and receptor KISS1R compared to fragments of intact peritoneum. The area of expression of receptor KISS1R in endometrioid heterotopies was reliably higher than the area of its expression in endometrium of patients with GE and in endometrium of women of the control group. Direct correlation between the area of protein expression (KISS) in endometrium with level kisspeptin on the 8th day of menstrual cycle in peripheral blood (rs = 0,90) has been revealed. It has been determined that the level of kisspeptin on the 2nd day of menstrual cycle in peripheral blood correlates with the area of expression of receptor KISS1R in peritoneum (rs = 0,57). A direct correlation between the area of expression of receptor KISS1R in peritoneum with the level of kisspeptin on the 8th day of menstrual cycle in serum has been found (rs = 0,90). Conclusion. The obtained data show a definite role of kisspeptin in pathogenesis of genital endometriosis. It can be assumed that the increase in the level of metastine (kisspeptin) in peripheral blood and increased expression of KISS1 in endometrioid heterotopies and especially its receptor KISS1R are compensatory-adaptive response aimed at deterrence of further spread of endometriosis. The obtained results justify the need to continue research in this direction for a deeper understanding of pathogenesis of the disease and possible use of kisspeptin as biomarker for non-invasive diagnostics as well as potential targeted therapy of GE.
