Purpose: To investigate the response to gabapentin treatment in patients with dry eye (DE) accompanied by features of neuropathic ocular pain (NOP), and to analyze the differences between clinical manifestations of the groups according to treatment response. Methods: We retrospectively reviewed the records of 35 patients with DE accompanied by NOP features and obtained information on their medical history and previous ocular history. The patients underwent clinical examinations of the tear film, ocular surface, and meibomian gland and completed the Ocular Pain Assessment Survey (OPAS). One month after treatment with topical eye drops, add-on of gabapentin treatment was determined according to the Wong–Baker FACES Pain Rating Scale (WBFPS). A reduction of 2 points or more on the WBFPS was considered a positive treatment response. Enrolled patients were divided into three groups according to the treatment response: topical treatment response group (group 1, n = 11); gabapentin response group (group 2, n = 13); and gabapentin non-response group (group 3, n = 11). The medical history, clinical parameters, and OPAS scores were compared between groups. Results: The incidence of systemic comorbidities was higher in group 2 than in other groups. The corneal staining scores were lower in groups 2 and 3 than in group 1. Among the treatment response groups, group 2 showed improvements in OPAS scores of ocular pain severity, pain other than eyes, and quality of life, while group 1 showed improved OPAS scores of ocular pain severity and ocular associated factors. Group 2 exhibited lower scores of pains aggravated by mechanical and chemical stimuli than group 3. Conclusions: Gabapentin could be effective in patients who have systemic comorbidity and less pain evoked by mechanical and chemical stimuli for the treatment of DE patients with NOP, which is refractory to topical treatment.

Purpose To evaluate the relationship of symptoms of dry eye with closed chamber infrared thermometry and humidity measurements. Methods The authors studied 54 patients (108 eyes) with dry eye disorders of different grades of clinical severity (mean age 35.75±14.37 years), 31 cases (62 eyes) with normal eyes (mean age 33.68±14.42 years), and 10 cases (20 eyes) with epidemic conjunctivitis (mean age 33.68±14.42 years). The symptoms and the clinical tests (Schirmer-1 test, fluorescein tear break up time, Lissamine green stain; closed chamber infrared thermometry and humidity) were used to establish the diagnosis of dry eyes. The closed chamber humidity difference was used to classify the groups of dry eye. Results The authors noted no temperature difference from closed to open eye position in dry eyes as compared to 0.10±0.00 °C difference in normal eyes and epidemic conjunctivitis. Four groups of cases were identified by difference in values of humidity: Group 1 = <0.9 relative humidity (RH)% to 1 RH%; Group 2 = >1 RH% to 1.5 RH%; Group 3 = >1.5 RH% to 2 RH %; and Group 4 = >2 RH%. The symptomatology was measured in the eyes using Oxford scale (0–4) and correlated with the humidity groups. The grading of symptoms with the humidity showed a statistically significant relationship (p<0.0001) in each group. The severity of the symptoms showed an increase in frequency and severity from Group 1 to Group 4, which was statistically significant (p<0.0001). The mean sum total of global symptomatology score was statistically significant (p<0.0001): 3.43±0.31 in Group 1, 4.65±0.42 in Group 2, 8.56±0.78 in Group 3, and 13.35±1.21 in Group 4. However, total symptomatology score in epidemic conjunctivitis did not show a statistically significant value (p=0.20). Conclusions The closed chamber humidity and thermometry measurements showed statistical correlation in all four groups of dry eyes to total mean symptomatology score (p<0.001) and showed an increase in value with increasing severity of symptoms. However, all individual symptoms fail to show any conclusive relationship.

Purpose: Comparison of dry eye syndrome stages with intensity of changes in peripheral retina in patients undergoing medical therapy. Material and methods. The clinical study involved 94 patients with mild and moderate dry eye syndrome (DES). Group 1 and Group 2 were both comprised of 25 patients; group 3 was comprised of 44 patients. The observation period was 6 months. Parameters of the anterior eye surface and intensity of changes in the peripheral retina were subjected to evaluation and comparison. Results. The study has shown, that the radius of the tear meniscus, surface tension coefficient and the number of areas stained with fluorescein significantly correlate with the probability of changes in the peripheral retina. The interrelation between the probable formation of changes in the peripheral parts of the retina and the indicators of tear production was revealed in all patients. After 3 months the performed treatment led to the disappearance of the initial correlation between the factors: on visits 3 and 4 logit-models appeared to be unreliable, that meant the absence of interrelation between the probability of formation of changes in the peripheral retina and indicators characterizing the condition of the anterior ocular surface or tear production. Conclusion. The correlation between changes in the peripheral parts of the retina and tear production was described.

Aim. The objective of the present study was the analysis of the tear fluid proteomic status and the eye surface of the patients presenting with ametropia before and after laser-assisted in situ keratomileusis (LASIK). Material and methods. The study included 163 patients (326 eyes) divided into three groups. Group 1 was comprised of 51 adult patients (102 eyes)at the age from 35 to 54 years suffering from high-degree myopia and astigmatism. Group 2 was composed of 26 adult patients (52 eyes) at the age from 35 to 55 years suffering from moderate or high-degree hyperopia and astigmatism. Group 3 consisted of 86 younger patients (172 eyes) at the age from 18 to 54 years suffering from high-degree myopia and astigmatism. The dry eye syndrome and the state pf the cornea were diagnosed with the use of the Lipkof’s test, Schirmer’s test, TBUT test, and corneal fluorescence staining. The antioxidant activity of the tears was estimated based on the results of measurements of peroxyredoxin-6 (PEDX6) expression. Results. The level of PEDX6 expression after LASIK increased in the patients presenting with myopia by 1.4 times and in those with hyperopia by 1.07 times, that is it changed but slightly after the operation and was 6.2 times less pronounced in comparison was the myopes. Conclusion. The study has demonstrated that two methods proved reliable for the evaluation of the tear fluid proteomic status, viz. the Lipkof’s test (1.82 ± 0.2mm, stage 3) and the TBUT test (8.0 ± 1.46 seconds), suggesting the presence of grade 2 dry eye syndrome. Te same refers to the patients of group 2: the results of the Lipkof’s test (1.31 ± 0.2mm) and the TBUT test (8.23 ± 0.87 seconds). The level of antioxidant protection of the ocular surface (PEDX6 expression) depended on the type of the refractive error: in the patients of group 1 before and after LASIK, PEDX6 expression was 4.7 times (13.57 ± 0.83) and 6.2 (19.31 ± 0.71) higher 2.88 ± 0.38 and 3.09 ± 0.47) than in those of group 2, respectively. In addition, it was shown that the level of antioxidant protection of the ocular surface (PEDX6 expression) depended on the age of the patients prior to LASIK: it was 1.3 lower in group 1 than in group 3 (1.35 ± 0.83 and 17.77 ± 1.03 respectively). The clinical significance of the tests for the tear fluid production and proteomic status changed appreciably after LASIK. The TBUT test for diagnostics of dry eye syndrome remained reliable in all the groups.

Background. The treatment of phlegmon of the maxillofacial area and neck at the present moment remains difficult and insufficiently effective. Aim. To develop a method of using photodynamic therapy (PDT) for the treatment of phlegmon of the maxillofacial area and neck and to evaluate its effectiveness. Material and methods. A total of 92 patients with phlegmons of the maxillofacial area and neck were under observation. They were divided into 3 groups: group 1 – “control group 1” (30 patients) – where traditional treatment was used, group 2 – “control group 2” (30 patients) – in which low-intensity laser radiation was used in addition to topical treatment and group 3 – “experimental” (32 patients) – where PDT was used for topical treatment. Results. The data of clinical, cytological and bacteriological studies show that the local application of PDT has an anti-inflammatory effect and stimulates the reparative processes in the wound, and shortens the treatment period for patients. Conclusion. PDT improves the results of complex treatment of patients with phlegmons of the maxillofacial area and neck. Its application leads to the purification of a purulent wound on the 3rd (3;4) day, allows to apply secondary sutures on the 7th day and to shorten the period of inpatient treatment in comparison with the control groups from 3 to 9 days.

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.

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.

Background: We hypothesized that perioperative HbA1c influenced the pattern and outcomes of Lower Extremity Amputation (LEA). Methods: A retrospective analysis was conducted for all patients who underwent LEA between 2000 and 2013. Patients were categorized into 5 groups according to their perioperative HbA1c values [Group 1 (<6.5%), Group 2 (6.5-7.4%), Group 3 (7.5-8.4%), Group 4 (8.5-9.4%) and Group 5 (≥9.5%)]. We identified 848 patients with LEA; perioperative HbA1c levels were available in 547 cases (Group 1: 18.8%, Group 2: 17.7%, Group 3: 15.0%, Group 4: 13.5% and Group 5: 34.9%). Major amputation was performed in 35%, 32%, 22%, 10.8% and 13.6%, respectively. Results: The overall mortality was 36.5%; of that one quarter occurred during the index hospitalization. Mortality was higher in Group 1 (57.4%) compared with Groups 2-5 (46.9%, 38.3%, 36.1% and 31.2%, respectively, p=0.001). Cox regression analysis showed that poor glycemic control (Group 4 and 5) had lower risk of mortality post-LEA [hazard ratio 0.57 (95% CI 0.35-0.93) and hazard ratio 0.46 (95% CI 0.31-0.69)]; this mortality risk persisted even after adjustment for age and sex but was statistically insignificant. The rate of LEA was greater among poor glycemic control patients; however, the mortality was higher among patients with tight control. Conclusion: The effects of HbA1c on the immediate and long-term LEA outcomes and its therapeutic implications need further investigation.
