BACKGROUND: Development and introduction of minimally invasive lifting techniques is considered a demanding and relevant objective of contemporary dermatocosmetology as these techniques result in nonsurgical lifting with minimal disruption of facial harmony due to the activation of a maximal number of key anatomic landmarks following the simultaneous insertion of lifting threads and hyaluronic acid fillers. AIMS: To study the clinical efficacy and safety of minimally invasive lifting technique and filling up of the tissue volume deficiency with the combination of thread lifting from the temporal approach and hyaluronic acid filler augmentation. MATERIALS AND METHODS: The study group included 193 female patients (mean age 41.3 8.5 years) with gravitational ptosis of the 1st, 2nd, and 3rd degrees. Group 1 (main) comprised 42 (21.8%) patients who underwent lifting by the method of implantation of 12 threads with shaped polydioxanone spikes DG-Lift and injection of 2 ml of hyaluronic acid biphasic filler. Group 2 (comparison) comprised 64 (33.2%) female patients who underwent lifting using only 1220 polydioxanone DG-Lift threads. Group 3 (comparison) comprised 87 (45%) female patients who received tissue volumization with 48 ml of biphasic hyaluronic acid filler in each case. RESULTS: A total of 82%, 59%, and 48% of patients in groups 1, 2, and 3, respectively, noted the optimal cosmetic result and full satisfaction with the result according to the Global Aesthetic Improvement Scale. The incidence of complications in group 1 (6.4%) was lower than that in group 2 (9.1%) and group 3 (17.7%). This is due to low invasive nature and lower tissue traumatization with the use of fewer fillers and threads to obtain optimal cosmetic effect. CONCLUSION: The proposed technique of thread lifting with biodegradable threads DG-Lift from the temporal approach combined with tissue volumization with hyaluronic acid fillers is safe and significantly effective for patients with gravitational ptosis of the 1st, 2nd, and 3rd degrees.

Abstract Aim To investigate the contribution of unaffected cardiomyocytes in Fabry disease cardiomyopathy. Findings Left ventricular (LV) endomyocardial biopsies from twenty-four females (mean age 53 ± 11 ys) with Fabry disease cardiomyopathy were studied. Diagnosis of FD was based on the presence of pathogenic GLA mutation, Patients were divided in four groups according with LV maximal wall thickness (MWT): group 1 MWT ≤ 10.5 mm, group 2 MWT 10.5–15 mm, group 3 MWT 16–20 mm, group 4 MWT > 20 mm. At histology mosaic of affected and unaffected cardiomyocytes was documented. Unaffected myocytes’ size ranged from normal to severe hypertrophy. Hypertrophy of unaffected cardiomyocytes correlated with severity of MWT (p < 0.0001, Sperman r 0,95). Hypertrophy of unaffected myocytes appear to concur to progression and severity of FDCM. It is likely a paracrine role from neighboring affected myocytes.

The study of platelet-rich plasma efficacy in the treatment of patients with knee osteoarthritis (OA) was performed. 188 patients were included and divided into three groups. Group 1 - 82 patients with OA, where hyaluronic acid was used for treatment, Group 2 - 36 patients, and Platelet Rich Plasma (PRP) and hyaluronic acid were used, Group 3 - 70 patients, only PRP was used. It`s been found that the use of PRP for treatment is characterized by a pronounced clinical efficacy compared with use of hyaluronic acid, which manifests in reduced detection rate of edema, hyperthermia and hyperemia. The use of PRP leads to pain reduction in the knee joint and increase the functionality of patients, that confirmed by more pronounced declining of visual analog scale indicators, Leken index and the WOMAC index values increase. The presented results of study are consistent with authors who believe that the lack of side effects and complications when using PRP indicates the safety of its use in clinical practice.

The osteochondral healing potential of hyaluronic acid (HA) plus diacerein was evaluated in subchondral-drilling- (SCD-) induced fibrocartilage generation in rabbits. A full-thickness chondral defect was created along the patellar groove of both knees and then SCD was subsequently performed only in the left knee. A week later, the rabbits were allocated into 3 groups to receive weekly intra-articular (IA) injection for 5 weeks with normal saline solution (NSS) (group 1) or with HA (group 2 and group 3). Starting at the first IA injection, rabbits were also gavaged daily for 9 weeks with NSS (group 1 and group 2) or with diacerein (group 3). The animals were then sacrificed for evaluation. The newly formed tissue in SCD lesions showed significantly better histological grading scale and had higher content of type II collagen in HA-treated group compared to NSS control. In addition, adding oral diacerein to HA injection enhanced healing potential of HA.

According to recent studies, the prevalence of dry eye syndrome makes up 14% of cases in patients under the age of 50 years and 65-75% in patients over 50 years of age. Risk factors for the development of dry eye syndrome include aging, stress, side effect of frequent instillations of eye preparations, exposure to radiant energy, and diabetes mellitus. Therefore, the purpose of this study is to investigate the possibility of using “Delargin”, an antioxidant medicine, in the treatment of dry eye syndrome. 50 patients (100 eyes) aged 30-70 years were examined at the Department of Ophthalmology and then divided into three groups depending on the treatment used. Group 1 included 10 patients (20 eyes), who were prescribed to instil Oksial eye drops. Group 2 included 10 patients (20 eyes), who received basic therapy by instilling a solution of sodium salt of hyaluronic acid 0.0015 g / ml. Group 3 involved 20 patients (40 eyes), who instilled Delargin and hyaluronic acid. Monitoring the effectiveness of the treatment was carried out using the following methods: to assess basal tear production, a Schirmer 1 test was performed using the Ophthalic Test diagnostic bands (India); a Norn test was performed to control the stability of the tear membrane. Fluorescence test (staining of the cornea with 1% sodium fluorescein solution) was applied to detect corneal defects; Lipcof test was used to assess the degree of lid-parallel fold formation of the bulbar conjunctiva relative to the costal margin of the lower eyelid. As a result of the treatment, the patients of the Group 1 demonstrated that the Norn test scores increased to some extent from 6.8 ± 0.1 s up to 7.5 ± 0.1 s; in the patients of the Group 2 following the treatment, it was 8.5 ± 0.2 s and in the Group 3, the Norn test values were 11.2 ± 0.2 s (P<0.05). The frequency of blinking movements decreased significantly and approached the normal. It has been found out that the therapy of dry eye syndrome that includes the antioxidant Delargin, can significantly promotes normalizing of parameters typical for this process.

Objective: This study aimed at examining whether topical treatment of colon anastomosis with hyaluronic acid can influence the healing of colonic anastomosis in rats treated with systemic corticosteroid. Methods: Three groups of Wistar rats weighing 252 ± 7g were used, with six rats each, all submitted to anastomosis of the proximal colon: Group 1 - control rats, without treatment. Group 2 - rats treated with subcutaneous (s.c) corticosteroid, and topical application of 0.9% saline solution over the anastomosis. Group 3 - rats treated with corticosteroid s.c. and topical application of 0.4% hyaluronic acid (10 mg/ml) on colonic anastomosis. On the 7th postoperative day, under anesthesia and laparotomy, the anastomosis site was subjected to the determination of rupture pressure. Then, samples containing the anastomosis site were resected and fixed in 10% buffered formaldehyde and embedded in paraffin. Masson H-E and trichrome staining. Histometry evaluated the infiltration of inflammatory cells at the anastomosis site, using a numerical scale from 0 to 4. Continuous variables were assessed using the Tukey test. Differences considered significant with p<0.05. Results: All animals survived the experiments. There were no abscesses, fistulas and macroscopically detectable dehiscences in the anastomosis site. The weight of the animals on the 7th postoperative day showed a statistically significant difference (p<0.001) between the control (253.6±6.3g) and corticoid (221.6±15.4g) groups, as well as between the corticoid +. hyaluronic acid group (257.8±9.7g) and corticosteroids (221.6±15.4). There was no significant difference in the comparison between the control and corticoid + hyaluronic acid groups (p>0.05). In the analysis of intraluminal pressure of colonic anastomosis, there was a statistically significant difference when comparing groups 1 (286.8±9.9 mmHg) and 2 (155±6.0 mmHg), 1 (286.8±9,9 mmHg) and 3 (199.1±7.7) and 2 (155±6.0 mmHg) and 3 (199.1±7.7), with p<0.001 for all comparisons. Histopathological classification by the numerical scale: Group 1 - inflammatory response (H-E) grade 3 and collagen deposition by Masson Trichomic grade 1; Group 2 - inflammatory response (H-E) grade 4 and deposition of collagen and fibroblasts by Masson's Trichrome grade1\2; Group 3 - inflammatory response (H-E) grade 3 and deposition of collagen and fibroblasts by Masson's Trichrome grade 1\2. There was no significant difference between groups. Conclusion: The topical use of hyaluronic acid has a positive influence on the initial healing phase of colonic anastomosis in rats treated with systemic corticosteroid.

Background Minimally invasive pedicle screw placement may have a higher incidence of violation of the superior cephalad unfused facet joint. Study Aims We investigated the incidence and risk factors of upper facet joint violation in percutaneous robot-assisted instrumentation versus percutaneous fluoroscopy-guided and open transpedicular instrumentation. Methods A retrospective study including all consecutive patients who underwent lumbar instrumentation, fusion, and decompression for spondylolisthetic stenosis and degenerative disk disease was conducted between January 2012 and January 2016. All operations were performed by the same surgeon; the patients were divided into three groups according to the method of instrumentation. Group 1 involved the robot-assisted instrumentation in 58 patients, group 2 consisted of 64 patients treated with a percutaneous transpedicular instrumentation using fluoroscopic guidance, and 72 patients in group 3 received an open midline approach for pedicle screw insertion. Results Superior segment facet joint violation occurred in 2 patients in the robot-assisted group 1 (7%), in 22 of the percutaneous fluoroscopy-guided group 2 (34%), and in 6 cases of the open group (8%). The incidence of facet joint violation was present in 5% (3) of the screws in group 1, 22% (28) of the screws in group 2, and 3% (4) of the screws in group 3. Conclusion Meticulous surgical planning of the appropriate entry site (Weinstein's method), trajectory planning, and proper robot-assisted instrumentation of pedicle screws reduced the risk of superior segment facet joint violation.

Summary. Background: Prosthetic vascular graft infection (PVGI) is a complication with high mortality. Cyanoacrylate (CA) is an adhesive which has been used in a number of surgical procedures. In this in-vivo study, we aimed to evaluate the relationship between PVGI and CA. Materials and methods: Thirty-two rats were equally divided into four groups. Pouch was formed on back of rats until deep fascia. In group 1, vascular graft with polyethyleneterephthalate (PET) was placed into pouch. In group 2, MRSA strain with a density of 1 ml 0.5 MacFarland was injected into pouch. In group 3, 1 cm 2 vascular graft with PET piece was placed into pouch and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. In group 4, 1 cm 2 vascular graft with PET piece impregnated with N-butyl cyanoacrylate-based adhesive was placed and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. All rats were scarified in 96th hour, culture samples were taken where intervention was performed and were evaluated microbiologically. Bacteria reproducing in each group were numerically evaluated based on colony-forming unit (CFU/ml) and compared by taking their average. Results: MRSA reproduction of 0 CFU/ml in group 1, of 1410 CFU/ml in group 2, of 180 200 CFU/ml in group 3 and of 625 300 CFU/ml in group 4 was present. A statistically significant difference was present between group 1 and group 4 (p < 0.01), between group 2 and group 4 (p < 0.01), between group 3 and group 4 (p < 0.05). In terms of reproduction, no statistically significant difference was found in group 1, group 2, group 3 in themselves. Conclusions: We observed that the rate of infection increased in the cyanoacyrylate group where cyanoacrylate was used. We think that surgeon should be more careful in using CA in vascular surgery.

SummaryWe have previously shown abnormalities of haemostasis suggestive of intravascular coagulation in patients with malignant hypertension, a condition associated with retinopathy and renal fibrin deposition. To determine whether such abnormalities are specific to malignant hypertension, we have measured several haemostatic and haemorheological variables in 18 patients with malignant hypertension (Group 1), 18 matched healthy controls (Group 2), and 18 patients with non-malignant hypertension (Group 3) matched for renal pathology, blood pressure and serum creatinine with Group 1. Both Groups 1 and 3 had increased mean levels of fibrinogen, factor VIIIc, beta-thrombo- globulin, plasma viscosity and blood viscosity (corrected for haematocrit); and decreased mean levels of haematocrit, antithrombin III and platelet count. Mean levels of fast antiplasmin and alpha2-macroglobulin were elevated in Group 1 but not in Group 3. We conclude that most blood abnormalities are not specific to malignant hypertension; are also present in patients with non-malignant hypertension who have similar levels of blood pressure and renal damage; and might result from renal damage as well as promoting further renal damage by enhancing fibrin deposition. However increased levels of fibrinolytic inhibitors in malignant hypertension merit further investigation in relation to removal of renal fibrin.

The purpose of the study was to conduct a comparative assessment of the course of the postoperative period after phlebectomy and thermal ablation in patients with varicose veins of the lower extremities in the system of the great saphenous vein (GSV) with class C2 of chronic venous insufficiency (CVI) — CEAP class C2. Materials and methods: 455 patients (455 limbs) with CEAP class C2. Group 1 (n = 154) received stripping + minimally invasive phlebectomy; Group 2 — endovenous laser ablation (EVLA) of GSV trunk + sclerotherapy of varicose veins; 3 group (n = 150) — radiofrequency ablation (RFA) of the GSV + sclerotherapy. All patients were united by a single tactical solution — the elimination of pathological vertical reflux in GSV. In each group, patients were with similar hemodynamic profile were selected (Group 1 = 63; Group 2 = 61; Group 3 = 61). The course of the postoperative period (from 2 days to 2 months) was compared for pain (visual analog scale — VAS), clinical symptoms of chronic venous insufficiency, degree of satisfaction (Darvall questionnaire), and duration of disability. Statistical processing was carried out using Excel programs for Windows XP, MedCalc® (version 11.4.2.0., Mariakerke, Belgium). Results: Postoperative pain is more pronounced (during day 1 for Group 1–4.0, Group 2–3.0, Group 3–2.0) and more prolonged (up to 4 days) after open surgeries (p < 0.05). The dynamics of the clinical symptoms of CVI (including varicose syndrome and use of compression therapy) could not be fully evaluated in connection with the ongoing sclerotherapy procedures for patients of Groups 2 and 3. Satisfaction of patients with aesthetic aspects was higher than expected in all groups. Reliable statistical differences proved decrease in days of disability (Group 1–14; Group 2–4; Group 3–3) and earlier return to physical activities and work in patients after thermal ablation in comparison with phlebectomy. Conclusion: The study shows that all three methods for eliminating vertical reflux in the GSV can be proposed for a large category of patients with CEAP of class C3 and C2. Medical and social rehabilitation of patients using endovascular thermal ablation technologies proceeds faster, which is beneficial both for the patients and for society.
