Five-year disease-free survival in FIGO IA stage endometrial cancer patients: Tertiary institution experience in a developing country.

Purpose: Endometrial cancer is characterized as histopathological, molecular, genetic, biological, and very diverse group of malignancies. Due to the need to precisely define the indications for adjuvant treatment in recent years, there has been a division made according to risk groups based on prognostic factors, which identify patients at risk for disease relapse, who may benefit from adjuvant therapy. The aim of this research was to examine the clinical and morphological factors that influence disease-free survival (DFS) and overall survival (OS) in patients with FIGO IA stage endometrial cancer. Material and methods: A retrospective clinical study was conducted, primarily based on the identification of factors that influence five-year DFS and OS. The study integrated data of FIGO IA stage endometrial cancer patients, who presented to gynecological oncology board for the first time after operative treatment, from January 1, 2016 to January 1, 2022. Adjuvant radiotherapy was applied to patients with an initially higher risk of disease progression. Length of survival was analyzed using Kaplan-Meier method, while log-rank test was used to assess differences between groups. Results: The results show that 5-year OS for 93 patients was 89.2% and DFS was 88.2%. Application of adjuvant brachytherapy, number of deliveries, MRI staging, type of institution where the surgery was performed influenced DFS. Pathohistological characteristics of tumor indicated a statistically significant impact on DFS. Conclusions: Application of adjuvant brachytherapy in high-intermediate and high-risk patients contributes to DFS increase. Moreover, the existence of a pre-operative MRI assessment of the stage of disease as well as the type of healthcare provided by an institution where the surgery was performed, significantly affect DFS.

High Fat Diet Exaggerate Metabolic and Reproductive PCOS Features by Promoting Oxidative Stress: An Improved EV Model in Rats.

Background and Objectives: Polycystic ovary syndrome (PCOS) is a frequent multifactorial endocrinopathy affecting women in the reproductive period, often associated with infertility and metabolic disorders. The use of animal models helps to better understand etiopathogenesis, enabling the examination of the effects of certain drugs in order to discover the best possible therapeutic approach. We tried to investigate the additional effect of estradiol-valerate (EV) and high-fat diet (HFD) in female rats to explore PCOS-related alterations with special focus on oxidative stress. Materials and Methods: Animals were divided into three groups: control group (CTRL, n = 6), estradiol-valerate group (EV, n = 6), and estradiol-valerate group on HFD (EV + HFD, n = 6). PCOS was induced by single subcutaneous injection of long-acting EV in a dose of 4 mg/per rat. We tried to improve the metabolic characteristics of the PCOS animal model by adding HFD, so the CTRL and EV group had a regular diet, while the EV + HFD group had HFD during the induction period of 60 days. Results: We observed alterations of anthropometric parameters and hormonal disturbances, along with estrus cycle impairment reassembly to obese-type PCOS phenotype. Moreover, glucose metabolism was impaired after addition of HFD to EV protocol, contrary to EV administered alone. Histological analysis confirmed more numerous cystic follicles after the combination of EV and HFD protocol. The alterations of oxidative stress markers could be related to and serve as the mechanistic base for development of PCOS-related endocrine, reproductive, and metabolic properties. Conclusions: The additive effect of EV and HFD was obvious in the majority of the parameters observed. Our study strongly demonstrated metabolic as well as reproductive properties of PCOS in rats.

Combined Treatment of Persistent Diabetic Macular Edema with Aflibercept and Triamcinolone Acetonide in Pseudophakic Eyes.

Background and Objectives: The main cause of the vision loss in diabetics is the development of diabetic macular edema, regardless of the stage of diabetic retinopathy. The paper aimed to examine whether the additional intravitreal application of triamcinolone acetonide to continuous anti-vascular endothelial growth factor therapy could improve therapeutic outcomes for pseudophakic eyes with persistent diabetic macular edema. Materials and Methods: twenty-four pseudophakic eyes with refractory diabetic macular edema, that had appeared despite three previously administered intravitreal injections of aflibercept, were divided into two groups (twelve eyes in each group). The first group continued to have aflibercept administered according to a fixed dosing regimen (once in two months). Triamcinolone acetonide 10 mg/0.1 mL (administered once per four months) was included for the second group, i.e., their treatment continued with a combination of aflibercept + triamcinolone acetonide. Results: The reduction in central macular thickness was higher in the eyes treated with combined therapy (aflibercept + triamcinolone acetonide) compared with the use of aflibercept alone during the entire 12-month follow-up period (3rd month p = 0.019; 6th month p = 0.023; 9th month p = 0.027; 12th month p = 0.031). As was evident from the p-values, the differences were statistically significant. No statistically significant difference was recorded for visual acuity: 3rd month p = 0.423; 6th month p = 0.392; 9th month p = 0.413; 12th month p = 0.418. Conclusions: Combined anti-vascular endothelial growth factor and steroid therapy leads to a better anatomical outcome of persistent diabetic macular edema in pseudophakic eyes, but does not lead to a more significant improvement in visual acuity than continuous anti-VEGF therapy alone.

The Potential of SGLT-2 Inhibitors in the Treatment of Polycystic Ovary Syndrome: The Current Status and Future Perspectives.

Polycystic ovary syndrome (PCOS) is the most frequent endocrinopathy during women's reproductive age. PCOS is a heterogeneous disorder featuring specific cardiometabolic properties. The association between the presence of metabolic disorders and PCOS supports the claim that the regulation of glycemic status is very important in these patients. There is a wide range of therapeutic options (including those treating diabetes mellitus type 2) with potential advantages available for the management of PCOS. Sodium-glucose cotransporter type 2 inhibitors (SGLT-2is) improve glucose metabolism, reduce fat tissue, lower blood pressure, reduce oxidative stress and inflammation, and protect the cardiovascular system. Currently, the use of SGLT-2is is not widespread in PCOS therapy, although these drugs represent a promising new therapeutic approach. Therefore, it is necessary to initiate further study in order to determine more effective therapies for PCOS and investigate the effect of SGLT-2is, both as a monotherapy and in combination with other drugs. It is necessary to understand the mechanisms underlying SGLT-2is in PCOS and their effects on long-term complications, especially since the gold standard treatment for PCOS, such as metformin and oral contraceptives, do not have long-term cardioprotective effects. The effects of SGLT-2is seem to involve cardiac protection, while diminishing endocrine and reproductive abnormalities in PCOS. In the current narrative review, we examine the most recent clinical evidence and discuss the potential applications of SGLT-2is for PCOS therapy.

Antimicrobial Treatment of Serratia marcescens Invasive Infections: Systematic Review.

Background: Serratia marcescens (SM) is a Gram-negative pathogen discovered by Italian pharmacist, Bizio, in 1819. According to the literature, S. marcescens is resistant to a wide range of antibiotics, including penicillin, cephalosporin, tetracycline, macrolide, nitrofurantoin, and colistin. We conducted a systematic review of published reports, determined what invasive infections could cause SM, and established the most appropriate antibiotic therapy. Methods: We registered this systematic review on the PROSPERO registry of systematic reviews-meta-analyses before we started our research (registration number CRD42022323159). The online searches of published studies were implemented via MEDLINE, the Cochrane Central Register of Controlled Trials, EBSCO, Scopus, Google Scholar, SCIndex, and the registry of clinical studies of human participants (ClinicalTrials.gov). Results: Our study included 32 published articles (9 case series and 23 case reports). There were 57 individual cases, respectively. The oldest patient was 97 years and the youngest patient was a newborn. S. marcescens was, in most cases, isolated from blood followed by urine and cerebrospinal fluid. In most cases, sensitivity was tested to cotrimoxazole (from 27 isolates, 10 showed resistance) followed by gentamicin (from 26 isolates, 3 showed resistance) as well as amikacin (from 21 isolates, none showed resistance). Patients died from an infection in 21 cases (31%). Conclusions: Treatment of SM infections should include carbapenems or aminoglycosides in combination with third-generation (and eventually fourth-generation) cephalosporin. Cotrimoxazole should be considered in cases of uncomplicated urinary infections.

High-frequency deep sclerotomy as adjunctive therapy in open angle glaucoma patients.

INTRODUCTION: Glaucoma is a chronic, progressive disease of the optic nerve that can cause vision loss and blindness. High-frequency deep sclerotomy (HFDS) is a novel ab interno procedure used to lower intraocular pressure (IOP). This study aims at examining hypotensive effects of HFDS in patients with medically uncontrolled primary open-angle glaucoma (POAG). METHODS: 23 patients (23 eyes) participated in this study. They were all affected by primary open-angle glaucoma and used maximum prescribed medical therapy. It is important to note that the target intraocular pressure (IOP) was not detected in any study participant. The target intraocular pressure is the highest IOP value at which no new damages of the optic nerve occur. The procedure was performed with a custom-made, high-frequency dissection probe by applying bipolar current of 500 kHz. Six pockets (1mm deep, 0.3mm high, and 6mm wide) were made ab interno in nasal sclera (through trabecular meshwork and Schlemm's canal). Tobramycin/dexamethasone and pilocarpine eye drops were administered postoperatively for a month. RESULTS: The mean value of the base intraocular pressure had been 25.6mmHg before the procedure. Significant complications were not recorded either during the surgery or in a post-operative follow-up period. The average IOP for our patients reduced by 8.6mmHG (33.6%) after a year. The mean value of the instilled anti-glaucoma eye drops had been 2.78 (SD=0.45) before the HFDS and 0.61 (SD=1.04) at the end of the research. The target IOP was not achieved in five cases (21.7% of our sample). DISCUSSION/CONCLUSION: This study presents the data on our first surgical experience with high-frequency deep sclerotomy that was conducted on 23 patients who had medically-uncontrolled, primary, open-angle glaucoma. The results indicate that HFDS is safe and efficient in reducing IOP.

IS A DECREASED NITRIC OXIDE CONCENTRATION AFTER TRIAMCINOLONE ACETONIDE INTRAVITREAL INJECTION ONE OF THE REASONS FOR INTRAOCULAR PRESSURE RISE?

Diabetic macular edema is the most common cause of vision loss in patients affected by diabetes mellitus. For eyes with persistent retinal thickening despite anti-VEGF therapy, treatment with intravitreal triamcinolone may be considered, especially in pseudophakic eyes. The aim of this study was to examine aqueous humor nitric oxide concentration changes in pseudophakic eyes with persistent diffuse diabetic macular edema after intravitreal injection of triamcinolone acetonide, as well as the potential impact of these changes on the intraocular pressure values. In 10 pseudophakic eyes with persistent diffuse diabetic macular edema, paracentesis of anterior chamber with aspiration of aqueous humor and nitric oxide concentration measurements were done on the day of the intravitreal application of 20 mg triamcinolone acetonide, and after 1, 3, 6 and 9 months. Also, we were recording intraocular pressure values before the intravitreal triamcinolone acetonide injection and during the next 9 months. One month after the intravitreal triamcinolone acetonide injection, we noticed a decrease of nitric oxide concentration (45.37±5.55 µmol/L) by 31.79% compared to the initial values (66.52±7.66 µmol/L). After that, nitric oxide concentrations began to rise slightly, and at the end of the ninth month the mean nitric oxide concentration was similar to that recorded at the beginning of the study. Intraocular pressure values had increasing trend one month after the intravitreal triamcinolone acetonide injection (23.70±4.08 mm Hg) compared to the initial values (16.21±1.55 mm Hg), but after nine months these values returned to normal levels. Decreased concentration of nitric oxide could be one of the reasons for increased intraocular pressure after intravitreal application of triamcinolone acetonide in the treatment of diffuse diabetic macular edema.

THE EFFECT OF PRIMARY ARGON LASER TRABECULOPLASTY ON INTRAOCULAR PRESSURE REDUCTION AND QUALITY OF LIFE IN PATIENTS WITH PSEUDOEXFOLIATION GLAUCOMA.

The aim of the study was to assess the impact of primary argon laser trabeculoplasty (ALT) on intraocular pressure (IOP) lowering and quality of life improvement in patients with pseudoexfoliative glaucoma. Sixty patients with newly diagnosed pseudoexfoliative glaucoma who underwent primary ALT (group 2) or medication therapy (group 1) were followed-up. The effect of ALT on IOP reduction, dry eye development and number of antiglaucoma drugs used was examined. Patients were examined at the beginning of the study and then after 6, 12, and 18 months. A statistically significant difference between IOP values was observed throughout the 18-month follow-up, with the highest significance recorded 6 months after ALT (p=0.009). Twelve months after the start of the study, the TBUT value was 6.0±0.8 s in group 1 and 8.4±0.7 s in group 2. In group 2, the value of Schirmer test was constantly above 10 millimeters. The number of antiglaucoma medications used in group 1 was statistically significantly higher as compared to group 2 throughout the 18-month study period. ALT was found to be better choice for temporary regulation of IOP in patients with pseudoexfoliative glaucoma.

Predicting Severity and Intrahospital Mortality in COVID-19: The Place and Role of Oxidative Stress.

SARS-CoV-2 virus causes infection which led to a global pandemic in 2020 with the development of severe acute respiratory syndrome. Therefore, this study was aimed at examining its possible role in predicting severity and intrahospital mortality of COVID-19, alongside with other laboratory and biochemical procedures, clinical signs, symptoms, and comorbidity. This study, approved by the Ethical Committee of Clinical Center Kragujevac, was designed as an observational prospective cross-sectional clinical study which was conducted on 127 patients with diagnosed respiratory COVID-19 viral infection from April to August 2020. The primary goals were to determine the predictors of COVID-19 severity and to determine the predictors of the negative outcome of COVID-19 infection. All patients were divided into three categories: patients with a mild form, moderate form, and severe form of COVID-19 infection. All biochemical and laboratory procedures were done on the first day of the hospital admission. Respiratory (p < 0.001) and heart (p = 0.002) rates at admission were significantly higher in patients with a severe form of COVID-19. From all observed hematological and inflammatory markers, only white blood cell count (9.43 ± 4.62, p = 0.001) and LDH (643.13 ± 313.3, p = 0.002) were significantly higher in the severe COVID-19 group. We have observed that in the severe form of SARS-CoV-2, the levels of superoxide anion radicals were substantially higher than those in two other groups (11.3 ± 5.66, p < 0.001) and the nitric oxide level was significantly lower in patients with the severe disease (2.66 ± 0.45, p < 0.001). Using a linear regression model, TA, anosmia, ageusia, O2 -, and the duration at the ICU are estimated as predictors of severity of SARS-CoV-2 disease. The presence of dyspnea and a higher heart rate were confirmed as predictors of a negative, fatal outcome. Results from our study show that presence of hypertension, anosmia, and ageusia, as well as the duration of ICU stay, and serum levels of O2 - are predictors of COVID-19 severity, while the presence of dyspnea and an increased heart rate on admission were predictors of COVID-19 mortality.

POSTOPERATIVE PAIN AND STRESS RESPONSE: DOES CHILD'S GENDER HAVE AN INFLUENCE?

Surgical procedure causes multisystem stress response reactions. The aim of this study was to assess whether gender has an impact on the level of neuroendocrine response to surgical stress and intensity of postoperative pain in children undergoing inguinal hernia repair surgery, as well as satisfaction of their parents with preoperative and postoperative care. The study included 60 children aged 3-6 years, all of them the only child in the family. All children included in the study were categorized as American Society of Anesthesiologists PS Class I, and divided into two groups: group 1 composed of 30 boys and group 2 composed of 30 girls. After oral premedication with midazolam, general anesthesia with endotracheal intubation was performed in all patients. Ketorolac, 1 mg.kg-1, was administered for postoperative analgesia. Serum cortisol was measured in all children preoperatively and postoperatively. The quality of postoperative analgesia was evaluated by Wong-Baker (FACES) scale, along with parental satisfaction. Male children who were the only child in the family had stronger neuroendocrine response to surgical stress and stronger intensity of postoperative pain. The parents of the girls expressed greater satisfaction with preoperative and postoperative care.

Role of optical coherence tomography in the early detection of macular thinning in rheumatoid arthritis patients with chloroquine retinopathy.

BACKGROUND: Chloroquine and hydroxychloroquine are drugs that are primarily used for the treatment of malaria and are also recommended for treating connective tissue disorders, autoimmune diseases, and some dermatological and inflammatory diseases. Treatment with these drugs has potential risk for the development of retinopathy, clinically characterized by bilateral pigment changes in the macula, as one serious ocular complication. The aim of this research was to evaluate the parafoveal and perifoveal macular retinal thickness, as central foveal thickness in adult patients with rheumatoid arthritis (RA) on chloroquine therapy using optical coherence tomography (OCT). MATERIALS AND METHODS: In this cross-sectional study, 56 RA patients (56 eyes) were included and examined. All patients were treated with chloroquine (tablets resochin or delagil) at a dose of 250 mg/day without treatment with steroids and other immunosuppressive drugs. Patients were divided into two groups, namely, Group I patients - no visible changes in the macula (26 patients) and Group II patients- with visible changes in the macula (30 patients). The central fovea thickness and parafoveal and perifoveal retinal thickness in all quadrants were measured by OCT and compared in both groups. RESULTS: There are a significantly higher number of eyes without thinning of the macula in Group I patients than in Group II (P < 0.001) patients. There are a higher number of patients with recorded parafoveal thinning in Group II patients, especially in the inferior, nasal, and temporal sectors, respectively (P < 0.05). CONCLUSION: Maculopathy is the main side effect of chloroquine therapy in RA patients that can be detected by OCT in the early stages of the macular involvement.

INTRAOCULAR PRESSURE CHANGES AFTER UNEVENTFUL PHACOEMULSIFICATION IN EARLY POSTOPERATIVE PERIOD IN HEALTHY EYES.

The aim was to determine early changes in intraocular pressure (IOP) following uneventful phacoemulsification and intraocular lens (IOL) implantation in healthy eyes. This prospective interventional case series study was conducted at Ophthalmology Department, Kragujevac Clinical Centre, Kragujevac, Serbia. The study included 123 eyes of 123 cataract patients, 66 women and 57 men, age range 50-88 (mean 70.73±7.94) years having undergone phacoemulsification and in-the-bag implantation of a foldable IOL. The patients were treated at Kragujevac Clinical Centre between June 2015 and May 2016. IOP was measured by Goldmann applanation tonometry preoperatively, then 4-6 hours, 18-24 hours and 7 days postoperatively by the same examiner. The mean IOP preoperatively was 15.10±2.68 mm Hg. In three patients, maximum measured IOP was 22 mm Hg. At 4-6 hours postoperatively, the mean IOP was 24.29±7.56 mm Hg (p<0.001), at 18-24 hours it was 18.37±4.80 mm Hg (p<0.001), and 7 days after the surgery the mean IOP was 16.24±2.90 mm Hg (p<0.05). The measured IOP values were statistically significant in all measured times. However, at 4-6 hours and 18-24 hours, the mean IOP value was highly statistically significant (p<0.001). Although 7 days after the surgery IOP normalized, the mean IOP value was statistically significant (p<0.05). In conclusion, our research showed that even eyes with normal preoperative values and uncomplicated phacoemulsification course can show very high IOP values postoperatively, which can cause pain, blurred vision and, rarely, compromise visual function.

Quantitative Analysis of Uveitis Macular Edema in Multiple Sclerosis Patients Receiving Deep Posterior Sub-Tenon Triamcinolone Acetonide Injection.

AIM: We aimed to analyze the effects of adjunctive posterior sub-Tenon capsule triamcinolone acetonide injection in the treatment of intermediate uveitis macular edema in multiple sclerosis patients that could not be controlled by systemic corticosteroid medications and immunomodulators. METHODS: The study included 30 eyes of 25 patients with multiple sclerosis who received a posterior sub-Tenon injection of 40 mg/mL triamcinolone acetonide. Parameters monitored for therapy efficiency were best-corrected visual acuity, intraocular pressure, central foveal thickness (CFT), and fluorescein angiography (FA) scores. RESULTS: Mean best-corrected visual acuity was significantly improved at the control visit 0.15 ± 0.10 versus baseline 0.40 ± 0.20 logMAR (p < 0.05). Six eyes showed intraocular pressure spikes requiring topical antiglaucomatous treatment. Mean CFT and FA scores were significantly decreased versus baseline (CFT: 345 ± 50 µm; FA score: 3.4 ± 1.0) compared with the 12-week control visit (CFT: 219 ± 35 µm; FA score: 1.6 ± 1.1; p < 0.001). CONCLUSION: Posterior sub-Tenon injection of triamcinolone acetonide significantly improved visual acuity and decrease macular edema in patients with intermediate uveitis associated with multiple sclerosis.

The importance of developing atherosclerosis in pseudoexfoliation glaucoma.

Background/Aim: Pseudoexfoliation syndrome (XPS) is an age-related systemic disorder characterized by increased production and accumulation of elastic microfibrillar material in different tissues of the body: skin, connective tissue portions of visceral organs, periphery blood vessels and the eye, as well. The aim of our study was to determine the significance of atherosclerotic changes in the carotid arteries in the development of XFS and pseudoexfoliation glaucoma (XFG). Methods: The study included 120 patients ­ 40 patients per each of the three defined groups: XFS group, XFG group and age- and sex-matched control subjects (control group) without XFG. Blood samples were collected from the patients before cataract surgery. Serum levels of total cholesterol, low-density lipoprotein ­ LDL, high density lipoprotein ­ HDL and triglycerides were analyzed by standard laboratory techniques. Standard ultrasonography of the carotid blood vessels was performed in all the participants. Results: Lipid's profile was disturbed in the patients with XFS and XFG with statistical significance p control group (p < 0.01). Systolic and diastolic pressure was elevated in the patients with XFS and XFG (p < 0.01). Resistance index was increased in the patients with XFG (p < 0.01). Intima-media thickness was prolonged in patients with XFG (p < 0.01). Conclusion: A disturbed lipid profile with elevated resistancy index and intima-media thickness and increased systolic and diastolic pressure were compulsory findings in patients with developed XFG. So, these factors could be considered as risk. It seems to be difficult to inhibit the process of pseudoexfolation production in the whole body, but it appears that with proper therapy (antihypertnesive, cardiotoncs, etc.) and adequate nourishing, the process of XFG development could be interrupted.

Nitric oxide and tumour necrosis factor alpha in the process of pseudoexfoliation glaucoma.

AIM: To establish the role of nitric oxide (NO), ascorbic acid and tumour necrosis factor-α (TNF-α) in the pathogenesis of pseudoexfoliation glaucoma (XFG). METHODS: Our study included 120 patients who were referred for cataract surgery. All patients were divided into four groups according to clinical findings: XFG, early and late pseudoexfoliation syndrome (XFS), and cataract (without pseudoexfoliation). Serum and aqueous humour levels of the ascorbic acid, NO and TNF-α were measured. The concentrations of the ascorbic acid and NO were measured by an appropriate spectrophotometric method. Enzyme-linked immunosorbent assay (ELISA) was used to determine TNF-α level. RESULTS: Aqueous humour concentration of ascorbic acid was significantly lower in patients with late XFS (0.61±0.11 mmol/L) and XFG (0.48±0.15 mmol/L) compared to patients with early XFS (0.9±0.15 mmol/L) and cataract (1.16±0.22 mmol/L), while there was no difference in serum concentration in all examined groups. Aqueous humour concentration of NO was significantly higher in patients with XFG (77.7±11.4 µmol/L) compared to patients with early XFS (50.27±9.34 µmol/L) and cataract (49.77±7.1 µmol/L), while serum concentration was increased in the early stage of XFS (73.26±8.29 µmol/L). Aqueous humour level of proinflammatory cytokine TNF-α was increased in patients with XFS (early 460.04±18.32 pg/mL; late 502.42±53.23 pg/mL) and XFG (510.34±43.07 pg/mL), while there was no difference in serum level in all examined groups of patients. CONCLUSION: Reduced ascorbic acid and elevated NO and inflammation related cytokine TNF-α level in aqueous humour of the patients with developed XFG suggest that oxidative stress induces local inflammation.

Proinflammatory Cytokines Induce XFG Development.

PURPOSE: To reveal the roles of proinflammatory cytokines within the process of pseudoexfoliation (PEX) production. METHODS: Our study included 120 patients referred to cataract surgery (early and late stage of pseudoexfoliation syndrome (XFS), pseudoexfoliation glaucoma (XFG), and control group). Serum and humor levels of cytokines were measured in a sample with high sensitivity enzyme-linked immunosorbent assay (ELISA) kit. RESULTS: Our findings revealed that TNF-α and IL-17, overlooked by IL-6 action in the early stage and in the phase of glaucoma, played the main role in the inflammation activation in the tissue in the early and late stage of XFS and in XFG. CONCLUSIONS: Local conditions cause chronic inflammation in the eye, subsequently activating fibrotic process with fibrotic tissue deposits in the eye.

Correlation between metabolic controls and changes in retina in patients having diabetes.

INTRODUCTION: Diabetes mellitus is as old as the human race. Retinopathy, being one of complications of diabetes mellitus, is the most common cause of blindness. This study was aimed at analyzing the correlation between retinopathy and duration of disease, metabolic control, and obesity. MATERIAL AND METHODS: The study sample consisted of 135 patients divided into the experimental group of 90 patients with retinopathy and the control group of 45 patients without retinopathy. The patients were exa- mined according to standard protocols: anamneses, endocrinology, ophthalmology exams, biochemical analyses, and anthropometric measurements. RESULTS: The average age of patients was 60.13 +/- 9.29 in the experimental group, while it was 57.55 +/- 4.85 in the control group. The average duration of disease was 11.71 +/- 5.8 and 14.40 +/- 7.68 in the control group experimental group, respectively. The following statistically essential differences between the control and experimental group were found: in duration of disease (11.71 +/- 5.85; 14.40 +/- 7.68; r = 0.000), in glycemia (7.02 +/- 2.20; 8.34 +/- 3.18; p = 0.000), in glycosylated hemoglobin A1C (HbA1C) (7.16 +/- 1.37; 8.22 +/- 2.05; r = 0.000), in triglycerides (1.92 +/- 0.72; 2.63 +/- 1.60; r = 0.001), and in body mass index (23.94 +/- 2.65; 27.66 +/- 15.13; r = 0.000). CONCLUSION: There is a positive correlation between duration of disease, glycosylated hemoglobin A1C, triglycerides, body mass index - obesity and retinopathy. A significant statistical correlation among those parameters has been found in patients with diabetic retinopathy.

Evaluation of central corneal thickness in patients with ocular hypertension and primary open-angle glaucoma.

AIM: To determine correlation between central corneal thickness (CCT) and applanation intraocular pressure (IOP) in normal patients with primary open angle glaucoma and patients with ocular hypertension. METHODS: Two-year retrospective study designed to determine correlation between CCT and IOP. Records of 121 patients were included in the study. Inclusion criteria were: IOP higher than 22 mm Hg for a group with ocular hypertension but without functional, morphological damage and progression, diagnosis of glaucoma for a group with open-angle glaucoma and normal ophthalmological results for a control group. Patients who were mono-oculus, patients with secondary glaucoma and who had surgical treatment were excluded. The patients were selectively grouped according to types of glaucoma, by gender and age. The IOP values were measured by Goldman's applanation tonometer, CCT values were determined using ultrasonic pachymeter, in the period from January 2011 to December 2012. RESULTS: Of total 121 subjects, 51 had primary open angle glaucoma (POAG), 40 had ocular hypertension (OHT) and 30 had normal ophthalmological findings (control group). The CCT values in OHT group 529.37+/-25.18 µm were greater than of both POAG, 501.02+/-14.04 µm and control group, 497.37+/-14.90 µm. The IOP values in OHT group were 20.25+/- 3.62 mm Hg, and in POAG group were 18.25+/-2.70 mm Hg, while in the control group they were 13.53+/- 3.62 mm Hg. CONCLUSION: Determination of CCT in patients with glaucoma is crucial, considering its impact on IOP values, which represents a parameter in glaucoma diagnosis, as well as monitoring further progress of ocular hypertension and patients diagnosed with glaucoma.

Tumor of orbit / Tumor orbitário

The cavernous hemangiomas are the most common intra orbital tumors found in adults of the middle age. Although histological benign, they can encroach on intra orbital or the adjacent structures (optic nerve) and be considered anatomically or positional malignant. We present a case report of orbital cavernous hemangioma of right orbit in young women after pregnancy, from Topola near Kragujevac (Central Serbia) with visual compromise and it's by trans-nasal endoscopic surgical management. Our patient was controlled and treated with the symptomatic therapy, topical therapy with artificial tears and surgical treatment. Our patient has optimal visual acuity of affected right eye after surgical treatment of orbital tumor. Surgical treatment of symptomatic orbital cavernous hemangioma is safe and effective, so that the cosmetic results are the important parameter to evaluate the clinical outcome.

Os hemangiomas cavernosos são os tumores intraorbitais mais comuns encontrados em adultos de meia-idade. Embora histológico benigno, eles podem invadir a área orbital ou intraorbital ou ainda as estruturas adjacentes (nervo óptico) e ser considerado anatomicamente ou posicional maligno. Apresentamos um relato de caso de hemangioma cavernoso orbital da órbita direita em mulheres jovens após a gravidez, a partir de Topola perto Kragujevac (Central Sérvia), com comprometimento visual e medicado por tratamento cirúrgico endoscópico transnasal. O paciente foi controlado e tratado com terapia, terapia tópica sintomático de lágrimas artificiais e tratamento cirúrgico. Nosso paciente tem acuidade visual ideal do olho direito afetada após o tratamento cirúrgico de tumor orbital. O tratamento cirúrgico do sintomático hemangioma cavernoso orbital é segura e eficaz, de modo que os resultados cosméticos são o parâmetro importante para avaliar o resultado clínico.
