Abstract
Sagliker syndrome (SS) is a rare, exaggerated form of chronic kidney disease (CKD)-mineral and bone disorder resulting from untreated secondary hyperparathyroidism due to CKD. Herein, we describe a 34-year-old male patient whose Tc-99m-methylene diphosphonate bone scintigraphy and Tc-99m-sestamibi parathyroid scintigraphy revealed hints of SS and exhibited its defining characteristics.

Abstract
OBJECTIVES To assess dysfunctional personality beliefs associated with specific personality disorders (PD), as well as psychopathological symptoms and psychological distress levels in central serous chorioretinopathy (CSC) patients. MATERIAL AND METHODS This cross-sectional study included acute and chronic CSC patients and age- and sex-matched healthy volunteers. Dysfunctional personality beliefs and psychopathological symptoms assessed with Personality Belief Questionnaire-Short Form and Symptom Check List-90 Revised (SCL-90-R), respectively, were compared between CSC patients and healthy volunteers and between acute and chronic CSC patients. MAIN RESULTS Of the 55 CSC patients included in the study analysis, 21 (38.2%) had acute and 34 (61.8%) chronic CSC. Avoidant PD (13.92±3.79 vs. 12.03±3.98, P=0.012) and obsessive-compulsive PD (13.94±3.95 vs. 12.27±3.75, P=0.025) scores on the PBQ-SF were significantly higher in CSC patients than in healthy volunteers. The PBQ-SF scores were similar between acute and chronic CSC patients. CSC patients scored significantly higher on the general severity index (GSI) and all symptom dimensions except phobic anxiety and psychoticism on the SCL-90-R. In addition, scores for obsessive-compulsive, depression, interpersonal sensitivity, paranoid ideation, and GSI were significantly higher in acute than in chronic CSC patients. CONCLUSIONS This first study investigating the relationship between CSC and dysfunctional personality beliefs indicates that CSC patients have higher levels of dysfunctional beliefs related to avoidant and obsessive-compulsive PD than healthy volunteers. These findings present a new aspect of the personality profile of CSC patients and point to a target for intervention, i.e., dysfunctional beliefs, through a cognitive-psychiatric approach.

Abstract
Objectives This study aimed to report the demographic and clinical characteristics of diabetic macular edema (DME) patients treated with intravitreal injection (IVI) of anti-vascular endothelial growth factors (anti-VEGF) and provide an overview of outcomes during routine clinical practice in Türkiye. Materials and Methods This retrospective, real-world study included 1,372 eyes (854 patients) treated with a pro re nata protocol by 21 ophthalmologists from 8 tertiary clinics on the Asian side of the Marmara region of Türkiye (MARMASIA Study Group). Five cohort groups were established by collecting the patients' baseline and 3, 6, 12, 24, and 36-month follow-up data, where each subsequent cohort may include the previous. Changes in best-corrected visual acuity (BCVA, approximate ETDRS letters) and central macular thickness (CMT, μm), number of visits and IVI, and rates of anti-VEGF switch and intravitreal dexamethasone implant (IDI) combination were evaluated. Results The 3, 6, 12, 24, and 36-month cohorts included 1372 (854), 1352 (838), 1185 (722), 972 (581), and 623 (361) eyes (patients), respectively. The mean baseline BCVA and CMT were 51.4±21.4 letters and 482.6±180.3 μm. The mean changes from baseline in BCVA were +7.6, +9.1, +8.0, +8.6, and +8.4 letters, and in CMT were -115.4, -140.0, -147.9, -167.3, and -215.4 μm at the 3, 6, 12, 24, and 36-month visits (p<0.001 for all). The median cumulative number of anti-VEGF IVI was 3.0, 3.0, 5.0, 7.0, and 9.0, respectively. The overall anti-VEGF switch and IDI combination rates were 18.5% (253/1372 eyes) and 35.0% (480/1372 eyes), respectively. Conclusion This largest real-life study of DME from Türkiye demonstrated BCVA gains inferior to randomized controlled trials, mainly due to the lower number of IVI. However, with the lower baseline BCVA and higher IDI combination rates in our cohorts, these gains were relatively superior to other real-life study counterparts.

Abstract
Objectives The purpose of the study was to contribute further to this debated topic by investigating the correlation of magnetic resonance imaging (MRI) findings with the clinical picture in lumbar spondylosis patients. Patients and methods This multicenter retrospective study (as part of the epidemiological project of the TLAR-OASG [Turkish League Against Rheumatism-Osteoarthritis Study Group]) included 514 patients (101 males, 413 females; mean age: 63.6±10.8 years; range, 40 to 85 years) who were diagnosed as lumbar spondylosis by clinical examination and direct X-ray between December 2016 and June 2018. Demographic characteristics of patients, Visual Analog Scale for pain, presence of radiating pain, Roland-Morris disability questionnaire, straight leg raise test, deep tendon reflexes, neurogenic intermittent claudication symptoms, any decrease of muscle strength, and abnormality of sensation were recorded. Lumbar MRI findings of the patients were recorded as positive or negative in terms of disc herniation, intervertebral disc degeneration, root compression, osteophytes, spinal stenosis. Statistical analysis was done to assess the correlation between the clinical symptoms, physical examination, and MRI findings. Results Correlation analysis of the MRI results and the clinical findings showed a significant correlation between straight leg raise test and root compression (p<0.001, r=0.328) and a significant correlation between neurogenic intermittent claudication and spinal stenosis (p<0.001, r=0.376). Roland-Morris disability questionnaire had a significant correlation with all MRI findings (p<0.05, r<0.200). Conclusion The results of this study corroborate the notion that diligent patient history and physical examination are more valuable than MRI findings, even though a higher incidence of abnormal MRI findings have been obtained in patients with disability and dermatomal radiating pain.

Abstract
PURPOSE This prospective clinical case series aimed to evaluate the effect of suprachoroidal implantation of mesenchymal stem cells (MSCs) in the form of spheroids as a stem cell therapy for retinitis pigmentosa (RP) patients with relatively good visual acuity. METHODS Fifteen eyes of 15 patients with RP who received suprachoroidal implantation of MSCs in the form of spheroids were included. Best-corrected visual acuity (BCVA), 10-2 and 30-2 visual field examination and multifocal electroretinography (mfERG) recordings were recorded at baseline, postoperative 1st, 3rd and 6th months during follow-up. RESULTS Baseline median BCVA of RP patients was 1.30 (1.00-2.00) logMAR. BCVA has improved to 1.00 (0.50-1.30), 0.80 (0.40-1.30) and 0.80 (0.40-1.30) at the postoperative 1st, 3rd and 6th months, respectively. The improvements from baseline to the 3rd and 6th months were statistically significant (p = 0.03 and p < 0.001, respectively). In the 30-2 VF test, median MD was significantly improved at the 6th month compared to baseline (p = 0.030). In the 10-2 VF test, the median MD value was significantly different at the 6th month compared to the baseline (p = 0.043). The PSD value of the 10-2 VF test was significantly different at the 6th month compared to the 3rd month (p = 0.043). The amplitudes of P1 waves in < 2°, 5°-10° and 10°-15° rings improved significantly at the postoperative 6th month (p = 0.014, p = 0.018 and p = 0.017, respectively). There was also a statistically significant improvement in implicit times of P1 waves in 10°-15° ring at the postoperative 6th month (p = 0.004). CONCLUSION Suprachoroidal implantation of MSCs in the form of spheroids as a stem cell therapy for RP patients with relatively good visual acuity has an improving effect on BCVA, VF and mfERG recordings during the 6-month follow-up period. Spheroidal MSCs with enhanced effects may be more successful in preventing apoptosis and improving retinal tissue healing in RP patients.

Abstract
PURPOSE This study aimed to evaluate the choroidal vascularity index (CVI) as an activity criterion in chronic central serous chorioretinopathy (CSC) and as a measure of treatment response after full-dose-full-fluence photodynamic therapy (fd-ff-PDT). METHODS This fellow-eye-controlled, retrospective cohort study included 23 patients with unilateral chronic CSC treated with fd-ff-PDT (6 mg/m2 ; 50 μcm2 ; 83 s). Subfoveal choroidal thickness (SFCT, μm) and CVI (%) of the affected and fellow eyes at baseline as well as at 1, 3 and 6 months after fd-ff-PDT were compared. RESULTS The patients' mean age was 43.4 ± 7.3 years, and 18 (78.3%) were male. CVI was comparable between the affected and fellow eyes at baseline (66.09 ± 1.56 vs. 65.84 ± 1.57, p = 0.59). However, it became significantly lower in the affected eyes 1 (64.45 ± 1.68 vs. 65.87 ± 1.19, p = 0.002), 3 (64.21 ± 2.08 vs. 65.71 ± 1.59, p = 0.009) and 6 (64.47 ± 2.19 vs. 65.62 ± 1.52, p = 0.045) months after fd-ff-PDT. The mean SFCT and the mean CVI were significantly decreased in the affected eyes at all follow-up visits compared with baseline after fd-ff-PDT (p < 0.001). CONCLUSION At baseline, CVI was comparable between affected and fellow eyes. Therefore, its use as an activity criterion in chronic CSC patients is questionable. However, it was significantly decreased in fd-ff-PDT-treated eyes, supporting its role as a measure of treatment response in chronic CSC.

Abstract
ABSTRACT 68 Ga-prostate-specific membrane antigen (PSMA) PET/CT scan for restaging revealed increased 68 Ga-PSMA uptake in cutis verticis gyrata (CVG) in a patient with prostate cancer. Cutis verticis gyrata is an uncommon disorder in which the scalp thickens and mimics the cerebral cortex with deep grooves and folds. Several studies have demonstrated 68 Ga-PSMA uptake in noncancerous conditions. This case illustrates another instance of a benign illness accompanied by increased 68 Ga-PSMA uptake.

Abstract
A new iridoplasty method is described, which uses the U-suture technique to repair traumatic mydriasis and large iris defects. Two 0.9 mm opposing corneal incisions were made. The needle was inserted through the first incision, passed through the iris leaflets, and removed through the second incision. The needle was reinserted through the second incision and removed through the first incision by re-passing the needle through the iris leaflets to form a U-shaped suture. The modified Siepser technique was applied to fix the suture. Thus, with a single knot, the iris leaflets were brought closer (shrinking like a pack), fewer sutures were used and fewer gaps were left. Satisfactory aesthetic and functional results were obtained in all cases in which the technique was applied. There was no suture erosion, hypotonia, iris atrophy, or chronic inflammation during the follow-up.

Abstract
This study aimed to demonstrate the laser retinopexy method through the gas bubble under a slit-lamp biomicroscope using a wide-field contact lens to treat rhegmatogenous retinal detachment (RRD) with pneumatic retinopexy (PR) and report its anatomical and functional results. This single-center, retrospective case series included RRD patients treated with PR using sulfur hexafluoride (SF6). The demographics, preoperative factors, and anatomical and functional outcomes were collected from the patient files. The single-procedure success rate of PR at postoperative 6th months was 70.8% (17/24 eyes), and the final success rate after secondary surgeries was 100%. The BCVA was better in the successful PR eyes at postoperative 3rd (p = 0.011) and 6th month (p = 0.016) than in failed eyes. No single preoperative factor was associated with PR success. The single-procedure success rate of PR using the laser retinopexy method through the gas bubble with a wide-field contact lens system seems comparable to the PR literature.

Abstract
OBJECTIVE This study aimed to evaluate the effect of peripherally inserted central venous catheterization on cerebral oxygenation by near-infrared spectroscopy in very low birth weight preterm infants. STUDY DESIGN Forty-one preterm infants (gestational age ≤32 weeks and birth weight ≤1,500 g) requiring peripherally inserted central venous catheter were included. Hemodynamic data and cerebral regional oxygen saturation values measured by near-infrared spectroscopy were prospectively collected before (T0) and every 5 minutes for 30 minutes following catheterization. When compared with baseline (T0) values, those values having relative maximum changes in the first 15 minutes and between 15 and 30 minutes were defined as T15 max and T30 max, respectively. Any change of more than a 10% decrease in baseline cerebral rSO2 was considered clinically significant. Additionally, any changes exceeding 20% in heart rate and mean arterial blood pressure values were considered significant. Following catheterization, the time interval to reach the baseline for cerebral regional oxygen saturation was noted. RESULTS Cerebral regional oxygen saturation values at T15 max and T30 max were found to have decreased significantly in 46 and 22% of patients, respectively. A statistically significant difference was observed between these two time periods (p = 0.002); no significant differences in heart rate, mean arterial blood pressure, or cerebral fractional oxygen extraction values at T15 max and T30 max were observed. All patients reached their baseline cerebral regional oxygen saturation in a median of 25 (15-60) minutes. CONCLUSION In very low birth weight preterm infants, monitoring cerebral regional oxygen saturation by near-infrared spectroscopy before and after peripherally inserted central venous catheterization may be useful in clinical practice. The assessment of factors affecting cerebral oxygenation and, in the case of low cerebral oxygenation, implementation of corrective actions before peripherally inserted central catheterization may offer a neuroprotective strategy. KEY POINTS · Monitoring cerebral rSO2 by NIRS during PICC line procedure might be useful in preterm infants.. · In this study, a significant decrease in cerebral rSO2 level following catheterization was observed.. · Implementation of corrective actions before PICC line procedure may offer a neuroprotective strategy..

Abstract
Systemic juvenile idiopathic arthritis (sJIA) is an important autoinflammatory disease whose first symptom is usually fever, and life-threatening conditions such as macrophage activation syndrome can develop when diagnosis and treatment is delayed. sJIA is an exclusion diagnosis, and there is no specific test that distinguishes it from other febrile diseases. We report the positron emission tomography/computed tomography (PET/CT) findings of sJIA in a 12-year-old girl who presented with fever, rash, and arthralgia. 18F-fluorodeoxyglucose (FDG) uptake was observed in the spleen, bone marrow, and lymph nodes in 18F-FDG PET/CT performed to investigate the etiology of fever of unknown origin. The result of excisional biopsy performed with the suspicion of lymphoma from the left cervical lymph node with intense 18F-FDG uptake was reported as reactive hyperplasia. PET/CT is an alternative diagnostic method for patients with fever of unknown origin. In this case report, we emphasize that in patients with sJIA, there may be intense fluorodeoxyglucose-avid lymph nodes that may lead to the consideration of lymphoproliferative disease, and PET/CT findings along with spleen and bone marrow involvement may overlap with lymphoma.

Abstract
Pulmonary alveolar microlithiasis is a rare disease characterized by accumulating intraalveolar small calcium phosphate stones. The disease is slow and does not show any signs in the early stages, but the shortness of breath, cough, and right heart failure may develop as it progresses. Methylene diphosphonate used in bone scintigraphy shows high uptake of calcium deposits in the alveoli and causes diffuse increased radiopharmaceutical uptake in the lungs.

Abstract
Objectives This study aims to evaluate the clinical, functional, and radiological features of hand osteoarthritis (OA) and to examine their relationships in different geographic samples of the Turkish population. Patients and methods Between April 2017 and January 2019, a total of 520 patients (49 males, 471 females; mean age: 63.6±9.8 years) with hand OA were included in the study from 26 centers across Turkey by the Turkish League Against Rheumatism (TLAR). The demographic characteristics, grip strengths with Jamar dynamometer, duration of hand pain (month), the severity of hand pain (Visual Analog Scale [VAS]), and morning stiffness were evaluated. The functional disability was evaluated with Duruöz Hand Index (DHI). The Kellgren-Lawrence (KL) OA scoring system was used to assess the radiological stage of hand OA. Results The DHI had significant correlations with VAS-pain (r=0.367, p<0.001), duration of pain (r=0.143, p=0.001) and bilateral handgrip strengths (r=-0.228, p=0.001; r=-0.303, p<0.001). Although DHI scores were similar between the groups in terms of the presence of hand deformity (p=0.125) or Heberden's nodes (p=0.640), the mean DHI scores were significantly higher in patients with Bouchard's nodes (p=0.015). The total number of nodes had no significant correlations with the VAS-pain and DHI score (p>0.05). The differences between the groups of radiological hand OA grades in terms of age (p=0.007), VAS-pain (p<0.001), duration of pain (p<0.001), and DHI (p<0.001) were significant. There were no significant differences between radiological hand OA grades according to the duration of the stiffness, grip strength, and BMI (p>0.05 for all). Conclusion In our population, the patients with hand OA had pain, functional disability, and weak grip strength. The functional impairment was significantly correlated with the severity of the pain, and the functional status was worse in high radiological hand OA grades.

Abstract
Staphylococcus hominis (S. hominis) is a coagulase-negative Staphylococci and an infrequent cause of endophthalmitis. Due to its ability to produce biofilm, especially in diabetic patients, strains may acquire antibiotic resistance. We present two cases of S. hominis endophthalmitis, one with acute endophthalmitis after intravitreal bevacizumab injection and one with chronic endophthalmitis following undiagnosed penetrating ocular trauma. Although there are only four published S. hominis endophthalmitis cases in the literature, to the best of our knowledge, there has been no previously published case after intravitreal bevacizumab.

Abstract
Straatsma syndrome is the triad of myelinated retinal nerve fibers, myopia, and amblyopia and may be associated with strabismus, nystagmus, hypoplastic optic nerve, and heterochromia iridum. The degree of anisometropia, presence of strabismus, extent of myelination, and macular involvement have been reported to be associated with poor visual acuity after occlusion therapy for amblyopia in this syndrome. Here we present two cases of Straatsma syndrome with different responses to occlusion therapy and discuss their treatment responses according to prognostic factors for post-occlusion visual acuity.

Abstract
PURPOSE To evaluate the effects of the Valsalva manoeuvre (VM) on the choroidal vascularity index (CVI) in healthy volunteers. METHODS This prospective, cross-sectional study included 60 eyes of 30 healthy volunteers. Enhanced depth imaging-optical coherence tomography scans of both eyes involving the fovea were taken, and a 1500 μm subfoveal choroidal area was selected for image binarization with open-access Fiji software. The binarized image was segmented into the stromal area (SA) and luminal area (LA), and CVI was calculated as the ratio (%) of LA to the total choroidal area (TCA). CVI, subfoveal choroidal thickness (SFCT), IOP, systolic and diastolic blood pressure were evaluated at rest and during the VM. RESULTS During the VM, a mean ± standard deviation increase in LA (0.02 ± 0.05 mm2 , p < 0.001) and CVI (1.72 ± 2.83%, p < 0.001) was observed, whereas SA (-0.02 ± 0.05 mm2 , p < 0.001) decreased. There was no significant change in TCA (0.00 ± 0.03 mm2 , p = 0.55) or SFCT (1.05 ± 10.92 μm, p = 0.46). There was a moderate positive correlation between the spherical equivalent refractive error (SE) and SFCT both at rest and during VM (r58 = 0.49, p < 0.0005 and r58 = 0.49, p < 0.0005, respectively). However, there was no significant correlation between SE and CVI either at rest or during VM (p = 0.11 and 0.06, respectively). In a multiple linear regression analysis, CVI was only associated with SFCT; however, SFCT was also associated with SE, both at rest and during VM (p < 0.001). CONCLUSION Valsalva manoeuvre increases CVI by choroidal vascular dilation as demonstrated by an increase in LA and a decrease in SA. Researchers should be careful about unintentional VM during examinations.

Abstract
ABSTRACT We present the 68Ga-PSMA and 18F-FDG PET/CT findings comparatively of a 67-year-old prostate cancer and malignant melanoma patient who had COVID-19 pneumonia 3 months ago. In 68Ga-PSMA PET/CT, ground-glass opacities showing markedly increased PSMA uptake were observed in the patient's lungs. It was learned that the patient had COVID-19 pneumonia 3 months ago and was treated in the intensive care unit for 13 days. In 18F-FDG PET/CT, FDG uptake was minimal in the same areas. In the midterm period after COVID-19 pneumonia, lung PSMA uptake is more intense than FDG, which may help better understand the disease's healing phase.

Abstract
OBJECTIVE To evaluate whether volumetric PET parameters such as metabolic tumor volume (MTV) and total lesion glycolysis (TLG) contributed to maximum standardized uptake value (SUVmax) in predicting prostate carcinoma in the prostate incidentalomas (PI) in 18F-FDG PET/CT. MATERIALS AND METHODS This retrospective study comprised 107 patients with PI of 4723 male patients who had undergone 18F-FDG PET/CT. SUVmax and volumetric PET parameters of PIs were assessed. MTV and TLG were acquired with each SUV threshold as 2.5, 3.0, 3.5, 4.0, 4.5, and 5.0. RESULTS The PI incidence was 2.3%, and the malignancy ratio of PI was 15.9%. According to further analysis results, 17 patients were in the malignant group, and 46 patients were in the benign group. Malignant PIs had higher SUVmax (10.6 vs. 6.4 and p<0.01), MTV (all p < 0.01) and TLG (all p < 0.01) than benign incidentalomas. All volumetric PET parameters had higher area under the curve (AUC) than SUVmax. SUVmax AUC was 0.835 [95% confidence interval (CI): 0.728-0.942]. MTV 2.5 and TLG 2.5 had the highest performance for predicting malignant PI.MTV2.5 AUC was 0.871 (95% CI: 0.775-0.968), and TLG2.5 AUC was 0.882 (95% CI: 0.797-0.967). Using TLG 2.5 greater than 29.8 as the cut-off point, the sensitivity and specificity for malignancy prediction were 94.1% and 82.6%, respectively. CONCLUSION In this study, in which the effectiveness of volumetric parameters in the diagnosis of PI was evaluated for the first time, it was shown that they could potentially have clinical value along with SUVmax.

Abstract
Background: Cohen Syndrome (CS) is an autosomal recessive multisystemic disorder characterized by various ophthalmologic findings, including retinal dystrophy and associated cystoid macular edema (CME), in which there was no known effective treatment approach.Material and Methods: We describe a CS patient with a homozygous c.62 T > G, p.(Leu21*) mutation in the VPS13B gene with a topical carbonic anhydrase inhibitor (CAI; brinzolamide %1, thrice daily) responding CME.Case Description: A seven-year-old girl with an established diagnosis of CS was referred with a primary complaint of nyctalopia. On ophthalmologic examination, bilateral decreased visual acuity and normal-appearing macula with mild optic disc pallor were present. However, the detailed evaluation revealed bilateral blunted foveal reflexes, barely visible foveal pigmentation, and slightly attenuated retinal vessels without any peripheral retinal pigmentary changes in dilated fundus examination, and CME on optical coherence tomography. Bilateral topical brinzolamide thrice daily was initiated for CME. Visual acuity increased, and CME was resolved except for minimal schisis at the inner nuclear layer level at the third-month follow-up visit and remained stable up to one-year follow-up. CME reappeared after five months of self-discontinuation of the patient's therapy but resolved again with treatment resumption.Conclusion: We report the first case of CME secondary to rod-cone dystrophy associated with CS showing improvement in anatomy and visual acuity with a topical CAI.

Abstract
Purpose To investigate the adherence rate of neovascular age-related macular degeneration (nAMD) patients in treat-and-extend (TAE) protocol to their anti-vascular endothelial growth factor (anti-VEGF) intravitreal injection (IVI) appointments and to evaluate the functional and anatomical outcomes of the patients who attended and did not attend their IVI appointments during the coronavirus disease 2019 (COVID-19) restriction period (RP). Methods The patients with nAMD having IVI appointments between March 16 and June 1, 2020 (RP in Turkey) were included in this retrospective study. For adherence analysis, the patients who attended (Group 1, n = 44) and who did not attend (Group 2, n = 60) their IVI appointment visits during the RP (VRP) were evaluated according to their last visit before the RP (V0). For outcome analysis, the patients who attend VRP and have follow-up (Group 1a, 46 eyes) and who did not attend VRP but later attended for follow-up (Group 2a, 33 eyes) were evaluated for functional (best-corrected visual acuity, BCVA [logMAR]) and anatomical (optical coherence tomography [OCT] disease activity) outcomes at the first visit after RP (V1) and last visit within six months after RP (V2). Patients received a complete ophthalmologic evaluation with anti-VEGF (Aflibercept) IVI administration at all visits. Results The adherence rate of the patients to VRP was 42.3% (44/104). The patients in Group 1 were significantly younger (mean ± SD years, 71.0 ± 8.1 vs. 74.7 ± 8.0, p = 0.024), had better median [IQR] BCVA at their first presentation (0.30 [0.54] vs. 0.61 [1.08], p = 0.023) and V0 (0.40 [0.48] vs. 0.52 [0.70], p = 0.031), and had less hypertension (36.4% vs. 58.3%, p = 0.044) than Group 2. The mean ± SD delay of planned IVI at VRP in Group 2a was 13.9 ± 6.2 weeks. Disease activity in OCT was significantly higher in Group 2a than Group 1a at V1 (60.6% vs. 32.6%, p = 0.025). In Group 2a, the median (IQR) BCVA was significantly worse at V1 (0.70 [0.58]) and V2 (0.70 [0.59]) than V0 (0.52 [0.40], p = 0.047 and p = 0.035, respectively). Conclusions More than half of the scheduled nAMD patients in TAE protocol missed their IVI visits during the RP, which resulted in a delay of their treatments. The delay of IVI treatment in those patients resulted in an increase in OCT disease activity and a decrease in BCVA.

Abstract
Purpose: To report and evaluate the incidence and risk factors of retinopathy of prematurity (ROP) and to assess the sensitivity and specificity of Turkish national screening guideline (NSG) in heavier infants with a birth weight (BW) of >1500 g.Methods: The data of 1784 preterm infants with BW>1500 g, who were screened between 2009 and 2016 in a university hospital in Turkey, were analyzed retrospectively. The rates of any stage and severe (treatment-requiring) ROP incidence were investigated. The possible protective and risk factors were evaluated with univariate analyses and logistic regression analysis.Results: The rate of any stage ROP was 14.1% (n = 251). Severe ROP was observed in 11 infants (0.6%), and 2 of the infants (0.1%) had a gestational age (GA)>32 weeks, which fell outside of the NSG. In logistic regression analysis, BW, GA, O2 therapy duration, and exchange transfusion were determined to be independent risk factors (respectively, p < .001, p < .001, P = .055, and P = .033). Furthermore, antenatal steroid therapy was determined to have a highly significant protective effect on ROP development (p < .001). The sensitivity of Turkish NSG in identifying severe ROP increased from 82% to 100% with the inclusion of risk factors in addition to GA and BW.Conclusion: This study shows the presence of severe ROP in mature and heavy infants in Turkey. The positive effect of antenatal steroid use and the negative impact of exchange transfusion have been demonstrated for ROP development in mature infants. Possible risk factors should be evaluated with GA and BW to avoid missing severe ROP.

Abstract
Central serous chorioretinopathy (CSCR) is the second most common maculopathy after diabetic maculopathy between the third and fifth decades of life. CSCR is characterized by serous neurosensory retinal detachment occasionally coexisting with retinal pigment epithelium (RPE) detachment. CSCR usually has good clinical prognosis, often resolving spontaneously within the first three months. However, some patients may have recurrent episodes and chronic disease. CSCR can cause permanent visual loss due to persistent neurosensory retinal detachment and RPE atrophy, especially in chronic cases. In recent years, verteporfin-photodynamic therapy applied with standard and low-dose/low-fluence protocols, anti-vascular endothelial growth factors, glucocorticoid antagonists, mineralocorticoid receptor antagonists, and subthreshold micropulse laser with varying parameters have been investigated as treatment options. In this review, we evaluated randomized and non-randomized case series conducted after 2000 that included at least 3 patients with chronic CSCR over 3 months in duration who were treated with current treatment options for chronic CSCR.

Abstract
BACKROUND The exact etiopathogenesis of fibromyalgia syndrome (FM) is still unclear but the pathogenesis of FM is associated with neurogenic inflammation. Allergic rhinitis (AR) is a common inflammatory and immunological disease of the nasal mucosa. As a result, it is known that neurogenic inflammation has a role in the pathophysiology of both FM and AR. OBJECTIVE The aim of this study was to evaluate AR and nasal allergic inflammation using nasal mucociliary clearance time (NMC) in FM patients. METHODS Forty-five FM patients and fifty healthy controls were included in the study. In both groups, AR was evaluated by total nasal symptom scoring (TNSS) and NMC was measured using saccharine transit time test (STT). RESULTS TNSS was positive in 9 patients (20%) in the FM group and no positivity in the control group. In FM group, the mean value of TNSS was higher than that of the control group (p= 0.0001). The average value of STT of FM patients was statistically significantly longer when compared to the control group (p= 0.0001). CONCLUSION The results we obtained suggest that there is a high possibility of coexistence of FM and AR. As a result, the coexistence of AR and FM cannot be denied but we believe that comprehensive clinical studies should be conducted on this subject.

Abstract
Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis with lipid-laden macrophages and fibrosis. Although ECD is a multisystemic disease, the most common finding is sclerotic bone involvement in the diametaphyseal regions of bilateral distal femur and in proximal and distal tibia. We present a 40 years old woman who for the last two years had various systemic symptoms, especially knee pain, polyuria and polydipsia. Although a "hot knee" pattern was seen in bone scintigraphy (BS), a femur biopsy was performed, due to the preliminary diagnosis of haematologic malignancy. The biopsy specimen showed only intense fibrosis. One year later while the patient was in our clinic, BS showed characteristic for ECD bone involvement. Bone biopsy specimens stained in hematoxylin and eosin showed dense fibrosis but not histiocytosis. However, after immunohistochemical staining with CD-68, histiocytes were discerned. In conclusion, the authors underline that ECD was diagnosed at a second diagnostic attempt both clinically and by specific staining pathology specimens.

Abstract
Objective Multiple imaging techniques may be used to evaluate the development of progressive renal damage in children with urinary tract infections (UTIs). The aim of this study was to compare the efficacy of Tc-99m dimercaptosuccinic acid (DMSA) scintigraphy and renal ultrasonography (USG) in detecting renal scars in children with UTIs.
Methods A total of 630 kidneys from 364 children were included in the study and the results of DMSA and USG of children with UTIs were evaluated retrospectively between January 2016 and October 2017. DMSA scintigraphy is accepted as the gold standard and it was compared with USG results.
Results The sensitivity, specificity, positive predictive value, and negative predictive value for USG in the detection of renal scarring was found as 57.1, 89.6, 40.8, and 94.4%, respectively.
Conclusions Although USG is known to be safe, readily available, and relatively inexpensive, the sensitivity of USG does not seem to be sufficient to identify the renal parenchymal damage. We concluded that USG cannot replace DMSA in the evaluation of renal scarring.

Abstract
In the literature, few studies have investigated the effects of melatonin on energy metabolism in skeletal muscle in endotoxemia. We investigated the effects of melatonin on tissue structure, energy metabolism in skeletal muscle, and antioxidant level of rats with endotoxemia. We divided rats into 4 groups, control, lipopolysaccharide (LPS) (20 mg/kg, i.p., single dose), melatonin (10 mg/kg, i.p., three times), and melatonin + LPS. Melatonin was injected i.p. 30 min before and after the 2nd and 4th hours of LPS injection. Antioxidant status was determined by glutathione (GSH) measurement in the blood. Muscle tissue was stained using modified Gomori trichrome (MGT), succinic dehydrogenase (SDH), and cytochrome oxidase (COX) and histological scored. Also the sections were then stained with hematoxylin and eosin. The stained sections were visualized and photographed. Creatine, creatine phosphate, adenosine triphosphate (ATP), adenosine diphosphate (ADP), and adenosine monophosphate (AMP) levels were investigated using high performance liquid chromatography (HPLC) in muscle tissue. In the Melatonin + LPS group, blood GSH levels were increased compared with the LPS group (P<0.01). Melatonin reduced myopathic changes in the LPS group according to the histopathologic findings. In addition, ATP values were increased compared with the LPS group (P<0.05). Our findings showed melatonin treatment prevented muscle damage by increasing ATP and GSH levels in rats with LPS induced endotoxemia.

Abstract
Panretinal photocoagulation (PRP) is a standard treatment for proliferative diabetic retinopathy. Conventional laser (CL) therapy is performed in one or more sessions in single spot mode. Visual disabilities have been reported after treatment with CL, including central vision loss due to macular edema and peripheral visual field loss resulting from extensive inner retinal scarring. Multispot laser (MSL) photocoagulation has recently been introduced to clinical practice. Studies comparing PRP conducted with MSL and CL have reported that MSLs resulted in less retinal tissue damage and pain, and greater patient comfort compared to CL. The aim of this review was to compare the efficacy and side effects of MSLs and CLs for diabetic retinopathy treatment.

Abstract
Diabetic retinopathy is the most common cause of legal blindness in developed countries at middle age adults. In this study diabetes was induced by streptozotocin (STZ) in male Wistar albino rats. After 3 months of diabetes, rights eye were injected intravitreally with green fluorescein protein (GFP) labelled bone marrow derived stem cells (BMSC) and left eyes with balanced salt solution (Sham). Animals were grouped as Baseline (n = 51), Diabetic (n = 45), Diabetic+BMSC (n = 45 eyes), Diabetic+Sham (n = 45 eyes), Healthy+BMSC (n = 6 eyes), Healthy+Sham (n = 6 eyes). Immunohistology analysis showed an increased retinal gliosis in the Diabetic group, compared to Baseline group, which was assessed with GFAP and vimentin expression. In the immunofluorescence analysis BMSC were observed to integrate mostly into the inner retina and expressing GFP. Diabetic group had prominently lower oscillatory potential wave amplitudes than the Baseline group. Three weeks after intravitreal injection Diabetic+BMSC group had significantly better amplitudes than the Diabetic+Sham group. Taken together intravitreal BMSC were thought to improve visual function.

Abstract
Background: Balneotherapy (BT) is a treatment modality that uses the physical and chemical effects of water, including thermomineral, acratothermal, and acratopegal waters. It has many effects on cardiovascular system. Aim: The aim of the study is to investigate the effects of 3-week BT on blood pressure of osteoarthritis (OA) patients with no hypertension (HT), and controlled or uncontrolled HT. Materials and Methods: The OA patients (n = 270) were divided into three groups: No HT, controlled HT, and uncontrolled HT. All the groups received BT in the facilities of our university hospital at the same time every day (10:00-11:30 AM) for 10 min per day, 5 days per week, for a total duration of 15 days in a 3-week period. Systolic and diastolic blood pressures and pulse rates were measured before and after BT on daily basis. Results: Overall, (1) the pulse rates of study groups measured after BT were significantly increased compared to before BT; (2) the systolic blood pressures of study groups measured before and after BT were found as comparable; and (3) the diastolic blood pressures of no HT and controlled HT groups measured before and after BT were not statistically significant (P > 0.05); however, in the uncontrolled HT group, the diastolic blood pressure showed a decreasing trend after BT (P < 0.05). Conclusions: In patients with OA, BT can be safely used without resulting in any meaningful changes in systolic and diastolic blood pressures in patients with normal and controlled HT but a decrease in diastolic blood pressure of patients with uncontrolled HT. This may be an advantage in OA patients having HT as comorbid disease.

Abstract
OBJECTIVES The aim of this study was to evaluate lung tissue histopathologic changes and the number of apoptosis with the increase of abdominal pressure. METHODS The study rats were randomly assigned into the following five groups: a sham operated group and groups 1, 2, 3 and 4, in which the intra-abdominal pressure was increased to 11, 15, 18 and 22 mmHg for 60 min, respectively. Lungs were harvested for histopathologic changes and the tissue apoptotic analysis were carried out in a blinded manner. RESULTS All of the data showed that the number of apoptotic cells and necrosis were increased in accordance with the pressure level. However, this increase was statistically significant, especially in groups 3 and 4 (18 and 22 mmHg, respectively; p < 0.05) when compared to the sham operated rats. There were no differences observed between groups 1 and 2 (11 and 15 mmHg, respectively) and the sham operated rats. There was also no difference between groups 1 and 2. There were findings of coagulation necrosis and the number of apoptotic cells linearly increased when the abdominal pressure was increased. The cut-off value was 15 mmHg. CONCLUSION The available findings suggest that intra-abdominal pressure greater than 15 mmHg could irreversibly damage pulmonary cells and both coagulation necrosis parameters and the number of apoptosis increase in accordance with the pressure level.

Abstract
BACKGROUND Dialysis patients experience psychosocial problems, such as anxiety, depression, social isolation, loneliness, helplessness, and hopelessness. All of these psychosocial problems can increase patients' need for holistic care, including attention to the person's environment and receiving support from family. If dialysis patients are better supported and cared for, these negative consequences might be prevented or at least decreased. This study was performed to determine the perceived social support from family and depression level of hemodialysis patients. METHODS In this study, descriptive design was used. Data were collected during structured interviews in an outpatient clinic using a questionnaire. The questionnaire aimed to determine the patients' descriptive characters and the scores of Beck Depression Inventory and Perceived Social Support from Family Scales. In data evaluation, descriptive statistics, Student's t tests, Kruskal Wallis tests, Mann-Whitney U tests and Pearson product moment correlations were used. RESULTS The mean depression score was very high (23.2 ± 10.5). Significant differences were found between employment status and level of depressive symptoms. The mean level of perceived social support from family was 15.23 ± 5.37. There were no statistically significant differences between all the variables for the level of perceived social support from family. Perceived social support from family was negatively correlated with depression. CONCLUSIONS The results of this study indicate that Turkish hemodialysis patients experience depression. However, patients who were dissatisfied with their social relationships had higher depression scores.
