The use of calprotectin and other inflammatory parameters in the investigation of pseudoexfoliation syndrome concomitant glaucoma and systemic diseases. Indian J Ophthalmol 2024; 72:S393-S397. [PMID: 38099372 DOI: 10.4103/ijo.ijo_914_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Accepted: 08/01/2023] [Indexed: 12/19/2023] Open
Abstract
PURPOSE The present study aimed to investigate the value of calprotectin and other inflammatory parameters in patients with glaucoma and systemic diseases accompanying pseudoexfoliation syndrome (PEX-S). METHODS This prospective study included 45 PEX-S patients and 45 non-PEX control patients. Patients were investigated for the presence of glaucoma, cardiovascular disease (CVD), ischemic brain disease (IBD), Alzheimer's disease, and neurosensory hearing loss (NSHL). After excluding diseases that may affect inflammatory parameters, a detailed biomicroscopic examination, and blood tests were performed for the patients. RESULTS Glaucoma, CVD, NVK, Alzheimer's disease, and NSHL were high in the PEX-S group ( P = 0.01, P = 0.01, P = 0.04, P = 0.04, and P = 0.03, respectively). Calprotectin, ferritin, neutrophil-to-platelet ratio, and lymphocyte-to-platelet ratio were found to be high in the PEX-S group ( P < 0.01, P = 0.04, P < 0.01, and P < 0.01, respectively). On evaluating the relationship between PEX-S and glaucoma and systemic diseases, it was found that elevated calprotectin increased the risk of glaucoma by 4.36 times and elevated neutrophil-to-lymphocyte ratio (NLR) increased the risk of CVD by 3.23 times in PEX-S patients ( P = 0.02 and P = 0.03, respectively). CONCLUSION This study demonstrated the value of calprotectin elevation in detecting concomitant glaucoma in PEX-S patients and, in addition, the value of NLR elevation in detecting concomitant CVD.

The effect of isotretinoin on meibomian glands in eyes: a pilot study. Int Ophthalmol 2022; 42:2071-2078. [PMID: 34978652 DOI: 10.1007/s10792-021-02205-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2020] [Accepted: 12/24/2021] [Indexed: 01/21/2023]
Abstract
PURPOSE The aim of this pilot study was to quantify the meibography changes in patients administered with oral isotretinoin. METHODS This prospective pilot study included 30 eyes of 30 patients who received oral isotretinoin treatment due to acne. Each patient underwent a general ophthalmological examination. After fluorescence staining of the ocular surface, the tear film break-up time (TFBUT) test, meibography and Schirmer test were carried out and noted. All of these procedures were applied before the treatment and repeated at 1, 3, and 6 months after the treatment. RESULTS The percentage of upper meibomian gland (MG) loss at 3 and 6 months after the treatment was 22.2% (p = 0.001) and 23.6% (p = 0.001), respectively. The percentage of lower MG loss at 3 and 6 months after the treatment was 18.7% (p = 0.001) and 20.7% (p = 0.001), respectively. The corneal fluorescein staining score at 3 and 6 months after treatment was 0.57 (p = 0.001), and 0.47 (p = 0.012), respectively. CONCLUSION These findings show that oral isotretionin treatment may affect MG morphology. The study findings also suggest that isotretinoin may cause tear film instability with Meibomian gland dysfunction and may cause evaporative type of dryness.

Comparison of trifocal toric and bifocal toric intraocular lens implantation in patients with cataract and high corneal astigmatism. Int J Ophthalmol 2021; 14:1876-1881. [PMID: 34926202 DOI: 10.18240/ijo.2021.12.10] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2021] [Accepted: 05/07/2021] [Indexed: 11/23/2022] Open
Abstract
AIM To investigate and compare the quality of life, satisfaction, contrast sensitivity, glare, depth perception, and intraocular lens (IOL) rotation in patients who underwent trifocal toric and bifocal toric IOLs. METHODS A total of 80 eyes of 40 patients were included in this prospective study. Twenty patients in each group were implanted with trifocal toric and bifocal toric IOL, respectively. Preoperative and postoperative 6-month measurements were recorded for both patient groups. Comprehensive anterior and posterior segment examinations, distance-intermediate-near visual acuity values and the visual function scale questionnaire results were evaluated at these examinations. Patient satisfaction, contrast sensitivity, glare, intermediate-near and distance stereopsis and IOL rotation were also evaluated. RESULTS No significant difference was found between the groups in terms of distance and near visual acuities (P=0.269, P=0.451). Intermediate visual acuity was significantly increased in the trifocal toric group (P<0.001). The visual function scale results were increased after surgery in both groups (P=0.001 and P<0.001), with no difference determined between them (P=0.158 and P=0.691). The number of patients wearing glasses was low in both groups and there was no significant difference between the groups (P>0.05). The overall satisfaction in the trifocal toric group was significantly higher than in the bifocal toric group (P=0.03). The highest sensitivity was observed at 6 cpd spatial frequency in all patients under photopic conditions (1.80±0.24 logU, 1.74±0.20 logU). Distance-intermediate-near binocular depth perception results in both groups were higher in the trifocal toric group (P=0.02, 0.048, 0.003, respectively). Although there was no significant difference for 3 meters stereopsis, the trifocal toric group had higher depth perception (P=0.577). Mean rotation was 5.76°±3.93° in the trifocal toric group and 12°±7.1° in the bifocal toric group. CONCLUSION Better results in the middle distance are obtained in the trifocal toric group and less IOL rotation due to digital system-coordinated surgery. Moreover, the overall satisfaction in the trifocal toric group is significantly higher than in the bifocal toric group.

Evaluation of ocular psoriasis with meibography. An Bras Dermatol 2021; 97:22-27. [PMID: 34785066 PMCID: PMC8799865 DOI: 10.1016/j.abd.2021.05.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Revised: 04/24/2021] [Accepted: 05/04/2021] [Indexed: 11/23/2022] Open
Abstract
Background Previous studies has shown that dry eye test abnormalities, meibomian gland dysfunction (MGD), may occur in psoriasis. Objectives The authors aimed to evaluate the dry eye disease (DED), MGD, in psoriasis patients with meibography which is a current, objective, noninvasive method for patients with meibomian gland diseases, to investigate the relationship between disease severity and ocular involvement. Methods This study included 50 participants with psoriasis and 50 healthy individuals. All subjects were examined by the same dermatologist and referred for ophthalmological examination including meibomian gland obstruction, lid margin alterations assessment, ocular surface disease index assessment, tear film break-up time test, Schirmer test, corneal conjunctival fluorescein staining assessment. Additionally, upper and lower lids were evaluated for meibomian gland loss with meibography. Results MGD (28%), meibomian gland loss (MGL) (29.5%), upper meiboscore (0.61 ± 0.81), lower meiboscore (0.46 ± 0.61), DED (22%) were significantly higher in the psoriasis group compared with the control group (p = 0.008, p < 0.001, p = 0.027, p = 0.041, p = 0.044, respectively). There was a significant relationship between MGD and psoriasis area severity index (PASI) (p = 0.015, Odds Ratio = 1.211). There was a significant positive relationship between MGL with PASI (p < 0.001, r = 608) and psoriasis duration (p < 0.001, r = 0.547). Study limitations Smaller study group and inability to detect quality changes of meibum with meibography were limitations of the study. Conclusions Psoriasis may affect the meibomian gland morphology, may cause structural changes in meibomian glands, and as a result of these may cause MGD and DED. Therefore, ophthalmologists and dermatologists should be aware of this situation and co-evaluate the patients in this respect.

Effect of methylphenidate as a dopaminergic agent on myopia: Pilot study. Int J Clin Pract 2021; 75:e14665. [PMID: 34324770 DOI: 10.1111/ijcp.14665] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Revised: 07/05/2021] [Accepted: 07/26/2021] [Indexed: 12/18/2022] Open
Abstract
Background Methylphenidate (MPH) hydrochloride is used as a first-line treatment for attention deficit hyperactivity disorder (ADHD). However, there is concern that this treatment may be associated with increased risk of refractive disorder. The aim of this study was to investigate the effect of MPH therapy on myopic shifts in refraction in children diagnosed with ADHD. Methods This study, children with ADHD and meeting inclusion criteria were examined before the initiation of MPH treatment and 3, 6 and 12 months after the initiation of treatment. Twenty age-gender-matched participants who applied to the outpatient ophthalmology clinic with various complaints were included in the study as a control group. Cycloplegic refraction examination and detailed eye measurements were performed at each visit. Results Nineteen patients were included in this study and the group consisted of 11 (57.9%) females and 8 (42.1%) males. The mean age of patients was 11.3 ± 2. (range: 8-18) years. During 12 months of use of MPH, the spherical equivalent changed from -0.36 ± 1.08 to -0.39 ± 1.05, and this difference was not statistically significant (P = .187). Axial length ranged from 22.92 ± 0.66. There was a change to 22.93 ± 0.62, and this difference was not statistically significant (P = .076). In the control group, the spherical equivalent changed from -0.43 ± 0.62 to -0.56 ± 0.84, and this difference was statistically significant. (P = .012) There was a change in the axial length from 22.97 ± 0.78 to 22.99 ± 0.62, and this difference was statistically significant (P = .015). Conclusions No significant changes spherical equivalent and axial length were detected during 12-month MPH use, but the increased spherical equivalent and axial length in the control group in the similar age group may indicate that MPH may reduce myopic shifts in refraction progression through dopamine, similar to in vivo studies. What's known Myopia is spreading rapidly in technologically advanced societies. There is strong evidence that myopia develops as the axial length of the eye increases as a result of spending more time indoors and working in close distances in parallel with the increase in education level. Animal studies have shown that decreased dopamine release plays an important role in the development of myopia. What's new The effect of dopamine in slowing or stopping myopia in experimental studies has also been demonstrated in human studies. No significant change in spherical equivalent and axial length was observed in methylphenidate users compared with control patients of similar age group. A significant increase in spherical equivalent and axial length was detected in the control group. This pilot study will shed light on future studies on the safe use of dopamine in the treatment of myopic shifts.

Evaluation of the agreement of optical biometry and Scheimpflug corneal topography with different axial lengths. J Fr Ophtalmol 2021; 44:1576-1583. [PMID: 34563406 DOI: 10.1016/j.jfo.2021.06.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Revised: 05/28/2021] [Accepted: 06/21/2021] [Indexed: 11/27/2022]
Abstract
PURPOSE To compare anterior segment parameters evaluated with optical low coherence reflectometry and combined Scheimpflug-Placido disc topography in eyes with different axial lengths. METHODS Deux cent quatre patients were divided into 3 groups according to their axial lengths. Central corneal thickness (CCT), anterior chamber depth (AD), mean keratometry value (K mean) and white-to-white distances (WTW) obtained from both devices were compared. All measurements were performed 3 times and averaged. RESULTS In group 1, a significant difference was detected between the two devices for CCT, WTW and Kmean measurements (P<0.001, P<0.001, p:0.005 respectively). In group 2, a significant difference was detected between the two devices for WTW measurement (P<0.001). In group 3, a significant difference was detected between the two devices for CCT and WTW measurement (P<0.001, P<0.001 respectively). In the Bland-Altman analysis, there was no match for Kmean obtained with both devices in group 1. In group 2, there was no agreement for AD obtained with both devices. In group 3, there was no match for AD, WTW or Kmean values obtained with both devices. CONCLUSION Some anterior segment parameters are not suitable for interchangeability in eyes with different axial lengths evaluated by Lenstar and Sirius anterior segment imaging systems. When planning critical surgery and treatment, more attention should be paid to measurements in eyes of different axial lengths.

Is pseudomyopia associated with anxiety and related disorders? Pak J Med Sci 2021; 37:1514-1518. [PMID: 34475940 PMCID: PMC8377937 DOI: 10.12669/pjms.37.5.3991] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2020] [Revised: 01/22/2021] [Accepted: 04/30/2021] [Indexed: 12/04/2022] Open
Abstract
Objectives: To investigate in detail the exact relationship between Pseudomyopia, also termed accommodative spasm, and psychiatric disorders. Methods: Twenty-one young people between the ages of 12-18 who were diagnosed with pseudomyopia between March 2019 and July 2020 in the ophthalmology eye clinic of a university hospital, Turkey were included in the study. A difference of at least 2.20 D between refractive error measurements before and after cycloplegic drop was accepted as pseudomyopia. Scl-90-r symptom screening scale was applied to each case. Afterwards, each case was evaluated by k-sads-pl-dsm-5-t semi-structured technique according to age. The relationship between psychiatric disorders in cases of pseudomyopia was examined. Results: The average age of patients in the study was 15,4 ± 1,9 (12-18), 13 (61,9%) girl and 8 (38,1%) boy. The mean initial refraction was -4,19D ± 2,48D (-1,75D /-8,50D), and the result refraction was +0,38D ± 0,22D (0,25D / -1,00D). The average amount of accommodation was 4,56D ± 2,59D (2,25D / 9,50D). Following the SCL-90-R screening scale and psychiatric evaluation, five generalized anxiety disorders, three obsessive compulsive disorders, three panic disorders, one social anxiety disorder, one posttraumatic stress disorder, one conversion disorder, one major depressive disorder were diagnosed. As a result, 15 (71,4%) of 21 patients were treated with a psychiatric diagnosis. In addition, a positive correlation (p: 0,010-r: 0,621, p: 0,029-r: 0,546) was detected between anxiety- somatization scores and accommodation amount. Conclusions: It is necessary to request psychiatric consultation in each case of pseudomyopia. Comorbidity of anxiety and depressive disorders is more common in pseudomyopia cases. In addition, as the severity of psychiatric symptoms increases, the amount of accommodation also appears to increase.

Abstract
Apart from the known factors that cause toxic optic neuropathy, there may be factors that have not yet been identified. We report a 32-year-old man who presented with a complaint of decreased vision. His optic discs were diffusely covered with a black pigment, and below were atrophic. The vessels appeared to have disappeared below the pigmentation. He reported smoking tobacco, drinking alcohol, and using cannabis. His vision in both eyes began decreasing gradually after he started using bonsai, a synthetic cannabinoid, 2 years previously. No case of toxic optic neuropathy with bilateral severe vision loss and intense pigmentation with the use of bonsai has been reported before, and our case will be reinforced if other such cases are reported in the future.

Abstract
Purpose: This study aimed to reveal the cause of meibomian gland disease and meibomian gland loss in patients with Sjögren's syndrome (SS) as the leading factor for dry eyes. Methods: The study included a total of 30 patients with SS and dry eye symptoms and a control group of 50 age- and gender-matched healthy subjects. The dryness parameters of all the participants were evaluated. At first, meibography was performed to measure meibomian gland loss using noninvasive methods. Later, meibomian gland expression and secretion quality were evaluated using silt-lamp biomicroscopy. Correlations between the measurements were analyzed statistically. Results: In patients with SS, MG loss was significantly greater than in the control group (19.7 ± 71%, 12.7 ± 9.6%, P < 0.001). All dry eye parameters (tear film breakup time, Schirmer's test score, OSDI, stain score, dry eye disease) were statistically significant in the SS group. There was an extremely negative correlation between upper MB loss and BUT (P = 0.08, r: 0.781). There was an extremely positive correlation between upper MB loss and staining (P = 0.015, r: 0.739). An extremely negative correlation was determined between sub-MB loss and BUT (P = 0.18, r:-0.781), and a moderately positive significant correlation was found between sub-MB loss and staining (P = 0.031, r: 0.659). Conclusion: The results of this study demonstrated that patients with SS were at a higher risk of being exposed to meibomian gland loss, which directly leads to the severe dry eye symptoms associated with SS.

Abstract
PURPOSE To investigate the effect of oral isotretinoin use on refractive error, axial length, and anteroposterior segment parameters. MATERIALS AND METHODS In this prospective study, 50 eyes of 50 patients using isotretinoin with a diagnosis of acne vulgaris and 50 eyes of 50 healthy control subjects were included. After detailed biomicroscopy, measurements were taken of axial length, lens thickness, central corneal thickness, anterior chamber depth, central retinal thickness, and subfoveal choroidal thickness. The pupils of both eyes were dilated with one drop of cycloplegic drops after refraction measurement. Visual acuity examination was performed with a Snellen chart the next day. The same procedure was repeated at the end of the third and sixth month of drug treatment. RESULTS Forty-seven patients with acne vulgaris and 45 healthy controls met the inclusion criteria and were included in the analysis. The mean ages of the patients and the controls were 21.7 ± 2.5 years (range, 18-28 years) and 22.6 ± 2.7 years (range, 19-27 years), respectively. No significant changes were observed in any parameters in the third and sixth month in the control group (p > 0.05). The most important result was significant increases in myopia and axial length in the sixth month of isotretinoin use (p = 0.01, p = 0.04, respectively). There were no significant relationships between increases in myopia and axial length and patients' age, sex, drug dose, and initial refraction (p > 0.05). The changes in spherical equivalent and axial length differed significantly between the drug group and the control group (p = 0.001, p = 0.001, respectively). CONCLUSIONS Isotretinoin is one of the important molecules in the aetiology of myopia. Oral isotretinoin treatment may increase myopia and axial length, although not to a clinically significant degree. However, as this was a pilot study, there is a need for further studies with more patients and longer follow-up periods.

Abstract
Background:Enthesitis-Related Arthritis (ERA), also referred as the juvenile ankylosing spondylitis, is a subtype of Juvenile Idiopathic Arthritis (JIA). However, ERA patients were reported as having higher pain levels, lower functional status and lower quality of life level compared to other JIA subtypes. Yoga is used as an exercise method in adult patients with rheumatic diseases and positive effects on physical and psychosocial symptoms were reported. However, no study was conducted related to yoga in pediatric population with rheumatic diseases.Objectives:The aim of this study was to investigate effects of performing yoga or home exercises on functional status in children with ERA.Methods:Twenty-one children with ERA were allocated into two groups as yoga group (n=11) and home exercise group (n=10). Yoga group performed yoga exercises supervised by a physiotherapist for twice a week, for eight weeks, while the home exercise group performed video-based home exercises for the same period. Pain in rest and activity (Numeric Rating Pain Scale), functional status (Six-Minute Walk Distance, Stair Climb Test), and quality of life (PedsQL Children and Parent Form) were evaluated at baseline and following eight weeks.Results:The groups were similar regarding to physical characteristics, pain, functional status, and quality of life at baseline (p>0.05, Table 1). While, all the parameters (except PEDSQL Parent Form) in yoga group significantly improved at the end of the study (p<0.05, Table 2), only stair climb test results significantly improved in home exercise group (p<0.05, Table 2).Table 1.Comparison of the groups at baselineYoga Group(n:11)Median (IQR 25/75)Home Exercise Group (n:10)Median (IQR 25/75)p*Physical parametersAge (year)15.0 (13.0/15.5)16.0 (14.0/17.0)0.099BMI (kg/m2)20.7 (18.3/23.1)21.2 (19.9/22.0)0.756PainRest pain (score)0 (0/5.0)1.0 (0/3.0)0.705Activity pain (score)4.0 (1.0/6.5)2.0 (0/7.0)0.387Functional StatusSix-minute walk distance (m)600.0 (552.5/664.5)626.0 (556.0/650.0)1.000Stair climb test (sec)7.6 (6.8/8.3)7.4 (7.0/8.0)1.000Quality of LifePedsQL Children (score)13.0 (10.0/23.5)12.5 (6.0/20.0)0.654PedsQL Parent (score)21.0 (8.5/31.5)26,0 (15.0/39.0)0.387*: Mann-Whitney U test; IQR 25/75: Interquartile Range 25/75, PedsQL: Pediatric Quality of Life Inventory, p<0.05Table 2.Changes in the GroupsBeforeMedian(IQR 25/75)AfterMedian(IQR 25/75)p*Yoga GroupPainRest pain (score)0 (0/5.0)0 (0/2.5)0.039Activity pain (score)4.0 (1.0/6.5)0 (0/1.5)0.012Functional StatusSix-minute walk distance (m)600.0 (552.5/664.5)692.0 (595.0/705.5)0.011Stair climb test (sec)7.6 (6.8/8.3)6.2 (6.0/7.0)0.008Quality of LifePedsQL Children (score)13.0 (10.0/23.5)9.0 (4.0/17.0)0.021PedsQL Parent (score)21.0 (8.5/31.5)18.0 (8.0/22.0)0.169Home Exercise GroupPainRest pain (score)1.0 (0/3.0)0 (0/3.0)0.715Activity pain (score)2.0 (0/7.0)2.0 (0/7.0)0.892Functional StatusSix-minute walk distance (m)626.0 (556.0/650.0)601.5 (585.0/707.0)0.093Stair climb test (sec)7.4 (7.0/8.0)7.0 (6.5/7.8)0.028Quality of LifePedsQL Children (score)12.5 (6.0/20.0)8.5 (7.0/18.0)0.475PedsQL Parent (score)26.0 (15.0/39.0)22.5 (14.0/30.0)0.192*: Wilcoxon Signed Rank Test, IQR 25/75: Interquartile Range 25/75, PedsQL: Pediatric Quality of Life Inventory, p<0.05Conclusion:Yoga seems promising for improving functional status in children with ERA compared to a home-based exercise program.

Abstract
OBJECTIVE To evaluate corneal parameters of rheumatoid arthritis (RA) patients by corneal topography. METHODS One hundred two RA patients and 60 control subjects were enrolled. Corneal topography measurements and ophthalmologic findings were examined from all participants' files. RESULTS Corneal thickness measurements were significantly lower in the RA group (p = 0.025). All values of corneal curvatures (K1, K2, Kmean) in 3 mm, 5 mm, and 7 mm zones were found statistically significantly higher in the RA group compared with the control group. Forty-five RA patients had a dry eye. Disease duration was correlated with dry eye in the RA group. There was a significant correlation between the duration of disease in RA patients and mean corneal curvatures (p 0.012/0.010/0.007, 3/5/7 mm respectively) and central corneal thickness (p 0.025). There is no statistical difference between other topographic measurements. CONCLUSIONS The results suggest that RA patients have thinner and steeper corneas compared with control subjects. These parameters change in negative correlation as the duration of the disease increases. Key Points • Rheumatoid arthritis is an autoimmune disease with systemic involvement. • In rheumatoid arthritis, systemic involvement is affected in the eyes. • When it comes to eye involvement, it comes to mind that it makes the eyes more dryness. • In addition to dryness in the eyes, rheumatoid arthritis makes morphological changes in the cornea.

Abstract
BACKGROUND AND PURPOSE To evaluate P-wave dispersion before and after antiepileptic drug (AED) treatment as well as to investigate the risk of ventricular repolarization using the Tpeak-Tend (Tp-e) interval and Tp-e/QT ratio in patients with epileptic disorder. METHODS A total of 63 patients receiving AED therapy and 35 healthy adults were included. ECG recordings were obtained before and 3 months after anti-epileptic treatment among patients with epilepsy. For both groups, Tp-e and Tp-e/QT ratio were measured using a 12-lead ECG device. RESULTS Tp-e interval, Tpe/QT and Tp-e/QTc ratios were found to be higher in the patient group than in the control group (p<0.05, for all), while QTmax ratio was significantly lower in the patient group. After 3 months of AED therapy, significant increases in QT max, QTc max, QTcd, Tp-e, Tp-e/QT, and Tp-e/QTc were found among the patients (p<0.05). When the arrhythmic effects of the drugs before and after treatment were compared, especially in the valproic acid group, there were significant increases in Tp-e interval, Tp-e/QT and Tp-e/QTc values after three months of treatment (p<0.05). Carbamazepine and levetiracetam groups were not statistically significant in terms of pre- and post-treatment values. CONCLUSION It was concluded that an arrhythmogenic environment may be associated with the disease, and patients who received AED monotherapy may need to be followed up more closely for arrhythmia.

Serum and vitreous resistin levels in patıents with proliferative diabetic retinopathy. Diabetes Res Clin Pract 2019; 155:107803. [PMID: 31362052 DOI: 10.1016/j.diabres.2019.107803] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2019] [Revised: 07/12/2019] [Accepted: 07/25/2019] [Indexed: 10/26/2022]
Abstract
AIM The aim of the study was to investigate the serum and vitreous levels of resistin in patients with the proliferative diabetic retinopathy (PDR) and to compare those with age-matched control subjects. METHODS The study included 45 eyes with PDR (group 1) and a control group of 22 (group 2). All eyes underwent vitrectomy surgery. The lipid profile, fasting blood glucose (FBG), HbA1c and resistin levels were investigated in blood samples of all subjects. Complete ophthalmological examinations were evaluated. Vitreous samples were collected from both groups during vitrectomy surgery and resistin levels were investigated in those samples. The results were evaluated using SPSS 9.0 software. RESULTS The demographic characteristics of the diabetic group and the control group were similar (p > 0.05). There was no significant difference between the groups in respect of mean visual acuity (VA), body mass index (BMI) values, or lipid profiles (p ˃ 0.05). There was no measurable value of resistin in the vitreous samples of all the eyes. The mean blood resistin level was 367 ng/ml in the control group and 387 ng/ml in the study group and the difference was not statistically significant (p > 0.05). CONCLUSIONS In the light of the findings of this study, it can be assumed that resistin did not pass through the vitreous at measurable levels. However, the serum resistin levels of the diabetic patients were higher than those of the control group although not statistically significant. Therefore, it can be considered that resistin does not play a major role in retinal neovascularization.

Abstract
AIM To investigate the prevalence of pseudoexfoliation syndrome (PEX) and its associations with ocular and systemic diseases in a population sample aged over 40y. METHODS A total of 2356 subjects were randomly chosen for the sample population based on the database of the Turkish Statistical Agency in Eskisehir. Of the invited 2356 subjects, 2017 subjects participated, out of which 2009 were eligible for the study. Systemic diseases, drug use, smoking and body mass index were assessed using questionnaires. Measurements of central corneal thickness (CCT), anterior chamber depth (ACD) and intraocular pressure (IOP) were performed during June to December, 2015. After pupillary dilation, the anterior segment and lenses were evaluated using a slit lamp. RESULTS Prevalence of PEX in this sample was 5.0% (n=100). Of patients with PEX, 26% also had glaucoma. Incidence of cataracts, and using drugs for hypertension, cardiac and psychiatric conditions was higher in patients with PEX compared to normal cases (P<0.05). Hearing loss was more common in PEX cases (34.0% vs 5.4%; P<0.001). The mean CCT, ACD and IOP were not significantly different between PEX and non-PEX cases. CONCLUSION This study is the first population-based, randomized trial in Turkey. Prevalence of PEX in patients over 40 years old was found to be 5.0%. Besides glaucoma and cataract, hypertension, hearing loss, using drugs for cardiac and psychiatric diseases were associated with PEX.

Abstract
OBJECTIVE Acromegaly is associated with increased cardiovascular morbidity and mortality. The data about the evaluation of coagulation and fibrinolysis in acromegalic patients are very limited and to our knowledge, platelet function analysis has never been investigated. So, we aimed to investigate the levels of protein C, protein S, fibrinogen, antithrombin 3 and platelet function analysis in patients with acromegaly. METHODS Thirty-nine patients with active acromegaly and 35 healthy subjects were included in the study. Plasma glucose and lipid profile, fibrinogen levels, GH and IGF-1 levels and protein C, protein S and antithrombin III activities were measured in all study subjects. Also, platelet function analysis was evaluated with collagen/ADP and collagen-epinephrine-closure times. RESULTS Demographic characteristics of the patient and the control were similar. As expected, fasting blood glucose levels and serum GH and IGF-1 levels were significantly higher in the patient group compared with the control group (pglc: 0.002, pGH: 0.006, pIGF-1: 0.001, respectively). But lipid parameters were similar between the two groups. While serum fibrinogen and antithrombin III levels were found to be significantly higher in acromegaly group (p fibrinogen: 0.005 and pantithrombin III: 0.001), protein S and protein C activity values were significantly lower in the patient group (p protein S: 0.001, p protein C: 0.001). Also significantly enhanced platelet function (measured by collagen/ADP- and collagen/epinephrine-closure times) was demonstrated in acromegaly (p col-ADP: 0.002, p col-epinephrine: 0.002). The results did not change, when we excluded six patients with type 2 diabetes in the acromegaly group. There was a negative correlation between serum GH levels and protein S (r: -0.25, p: 0.04)) and protein C (r: -0.26, p: 0.04) values. Likewise, there was a negative correlation between IGF-1 levels and protein C values (r: -0.39, p: 0.002), protein S values (r: -0.39, p: 0.001), collagen/ADP-closure times (r: -0.28, p: 0.02) and collagen/epinephrine-closure times (r:-0.26, p: 0.04). Also, we observed a positive correlation between IGF-1 levels and fibrinogen levels (r: 0.31, p: 0.01). CONCLUSION Acromegaly was found to be associated with increased tendency to coagulation and enhanced platelet activity. This hypercoagulable state might increase the risk for cardiovascular and cerebrovascular events in acromegaly.

Abstract
BACKGROUND The association between periatrial adiposity and atrial arrhythmias has been shown in previous studies. However, there are not enough available data on the association between epicardial fat tissue (EFT) thickness and parameters of ventricular repolarization. Thus, we aimed to evaluate the association of EFT thickness with indices of ventricular repolarization by using T-peak to T-end (Tp-e) interval and Tp-e/QT ratio. METHODS The present study included 50 patients whose EFT thickness ≥ 9 mm (group 1) and 40 control subjects with EFT thickness < 9 mm (group 2). Transthoracic echocardiographic examination was performed in all participants. QT parameters, Tp-e intervals and Tp-e/QT ratio were measured from the 12-lead electrocardiogram. RESULTS QTd (41.1 ± 2.5 vs 38.6 ± 3.2, p < 0.001) and corrected QTd (46.7 ± 4.7 vs 43.7 ± 4, p = 0.002) were significantly higher in group 1 when compared to group 2. The Tp-e interval (76.5 ± 6.3, 70.3 ± 6.8, p < 0.001), cTp-e interval (83.1 ± 4.3 vs. 76±4.9, p < 0.001), Tp-e/QT (0.20 ± 0.02 vs. 0.2 ± 0.02, p < 0.001) and Tp-e/QTc ratios (0.2 ± 0.01 vs. 0.18 ± 0.01, p < 0.001) were increased in group 1 in comparison to group 2. Significant positive correlations were found between EFT thickness and Tp-e interval (r = 0.548, p < 0.001), cTp-e interval (r = 0.259, p = 0.01), and Tp-e/QT (r = 0.662, p < 0.001) and Tp-e/QTc ratios (r = 0.560, p < 0.001). CONCLUSION The present study shows that Tp-e and cTp-e interval, Tp-e/QT and Tp-e/QTc ratios were increased in subjects with increased EFT, which may suggest an increased risk of ventricular arrhythmia.

Abstract
Background Ivabradine is a novel specific heart rate (HR)-lowering agent that improves
event-free survival in patients with heart failure (HF). Objectives We aimed to evaluate the effect of ivabradine on time domain indices of heart rate
variability (HRV) in patients with HF. Methods Forty-eight patients with compensated HF of nonischemic origin were included.
Ivabradine treatment was initiated according to the latest HF guidelines. For HRV
analysis, 24-h Holter recording was obtained from each patient before and after 8
weeks of treatment with ivabradine. Results The mean RR interval, standard deviation of all normal to normal RR intervals
(SDNN), the standard deviation of 5-min mean RR intervals (SDANN), the mean of the
standard deviation of all normal-to-normal RR intervals for all 5-min segments
(SDNN index), the percentage of successive normal RR intervals exceeding 50 ms
(pNN50), and the square root of the mean of the squares of the differences between
successive normal to normal RR intervals (RMSSD) were low at baseline before
treatment with ivabradine. After 8 weeks of treatment with ivabradine, the mean HR
(83.6 ± 8.0 and 64.6 ± 5.8, p < 0.0001), mean RR interval (713
± 74 and 943 ± 101 ms, p < 0.0001), SDNN (56.2 ± 15.7 and
87.9 ± 19.4 ms, p < 0.0001), SDANN (49.5 ± 14.7 and 76.4 ±
19.5 ms, p < 0.0001), SDNN index (24.7 ± 8.8 and 38.3 ± 13.1 ms,
p < 0.0001), pNN50 (2.4 ± 1.6 and 3.2 ± 2.2 %, p < 0.0001),
and RMSSD (13.5 ± 4.6 and 17.8 ± 5.4 ms, p < 0.0001)
substantially improved, which sustained during both when awake and while
asleep. Conclusion Our findings suggest that treatment with ivabradine improves HRV in nonischemic
patients with HF.

Abstract
OBJECTIVE To analyze the coronary angiograms of patients with symptomatic heart disease in order to determine the frequency and characteristics of coronary-cameral communications (CCCs) in a single center. SUBJECTS AND METHODS The coronary angiograms of 16,573 patients with symptomatic heart disease performed from November 2001 to January 2011 were analyzed. The diagnosis of coronary fistula and coronary-cameral microcommunications (CCMCs) was made according to previously defined criteria. RESULTS Of the 16,573 patients, 15 (0.09%; 8 males and 7 females, mean age 63 ± 12 years) had CCCs, while coronary fistulas were identified in 2 (0.01%). In the first patient, the coronary fistula arose from the branches of the left anterior descending (LAD) artery and the right coronary artery (RCA) and drained into the right ventricle. In the second patient, the fistula originated from branches of the LAD artery, the circumflex (Cx) artery and the RCA and drained into the left ventricle. In 7 patients, the CCMCs originated from the LAD artery. In 3 patients, the Cx artery was the origin. The CCMCs originated from the RCA in 2 patients. In 1 patient the CCMC took its origin from the RCA and the Cx artery, while in 2 patients the CCMCs were associated with intracardiac masses in the left atrium and the right atrium, respectively. CONCLUSION The prevalence of CCCs in adult patients was low and that of large coronary fistulas was even lower; coronary fistulas are probably very rare in adult patients because the majority of them are detected and treated during childhood.

Abstract
PURPOSE To show the effects on lung function of the opening pleura in patients undergoing cardiac surgery. SUBJECTS AND METHODS 66 patients were included. Patients were allocated into two groups. In group 1 (n=21) pleura was intact, in group 2 (n=45) pleura was opened. Both groups were compared prospectively in terms of preoperative and on the post-operative 5th day pulmonary function tests (PFT), preoperative, postoperative first and fifth day arterial blood gas analysis, preoperative and postoperative first day mixt venous oxygen saturation, bleeding, operation periods, pulmonary complications, intensive care and hospital stay period and mortality. RESULTS There was significant decrease in all PFT indicators on 5th post-operative day in group 2 (p < 0.01). Although there was a significant decrease in FEV1 on 5th post-operative day in group 1 (p < 0.001), other pulmonary functions parameters were not change significantly (p > 0.025). In group 2 much more decline in pulmonary function test parameters than group 1 were observed (p < 0.05). There was not statistically significant difference in blood gas analysis and mixed venous oxygen saturation values in group 1 (p > 0.05). But in group 2 except pH and PaCO2, other blood gas measurements were significantly decreased on the postoperative first and fifth day (p < 0.008). In group 2 except pH and PCO2, other parameters were less than the other Group (p < 0.01). The drained amount was still significantly higher in group 2 (p < 0.001). The frequency of the revision due to bleeding was observed much more in group 2. CONCLUSIONS Protection of the integrity of pleura may have positive effects on pulmonary functions in cardiac surgery.

Abstract
PURPOSE It has been known that inflammatory mechanisms play an important role in the coronary artery disease. Our aim in this study was to investigate the relationship between the neutrophil/lymphocyte (N/L) ratio and coronary flow velocity after primary percutaneous coronary intervention (PCI) in patients presenting with ST-segment elevation myocardial infarction (STEMI). METHODS Two hundred and ten patients who had undergone primary PCI were included. The coronary flow velocities were evaluated using the recorded PCI procedures by Thrombolysis in Myocardial Infarction (TIMI) flow grades and corrected TIMI frame counts (cTFC) values. A value of >40 for the final cTFC was accepted as an index of insufficient coronary blood flow. The white blood cell subtypes and counts were determined in the blood samples obtained at the clinics. RESULTS In 165 (78%) of the investigated patients, reperfusion was found to be sufficient (Group I) while in 45 (22%) of them (Group II) insufficient reperfusion was observed (Group II). In-hospital mortality was 7.2% (n=12) in Group I, whereas it was 17.7% (n=8) in Group II (P=0.033). Similarly, one-year mortality was higher in Group II (26.6%, n=12) than in Group I (13.3%, n=22) (P=0.031). N/L ratio was determined to be higher in Group I than in Group II (8.3±6.1 vs. 6.2±5.0; P=0.034). Also, N/L ratio was found as an independent predictor of severe no-reflow development (TIMI 0-1) and of one-year mortality (P=0.01 and P=0.047, respectively). CONCLUSIONS N/L ratio has been found to be an independent indicator for no-reflow development in patients who have undergone PCI for acute STEMI. This simple and low-cost parameter can provide useful information for the relevant risk evaluation in these patients.

Abstract
Myocardial bridging is one of the nonatherosclerotic causes of coronary artery disease and is characterized by muscles overlying the intramyocardial course of a major epicardial coronary artery segment, leading to systolic compression. Myocardial bridging is considered a benign condition in most cases, but has been associated with serious cardiac events such as myocardial infarction and sudden death. We discuss the case of a 63-year-old man who was admitted to our hospital with effort-induced angina, bradycardia, and left ventricular hypertrophy on electrocardiogram. On coronary angiography, we found significant myocardial bridging with total occlusion in the left anterior descending artery during systole. In patients with myocardial bridging, symptoms often manifest during exercise and with tachycardia. But it is interesting to note that our patient was bradycardic and became symptomatic with minimal effort. Thus, we thought that these emphasized its significance and affected treatment strategy.

The role of fibrinolytic system in no-reflow after stenting with and without predilation in patients with acute coronary syndromes. J Thromb Thrombolysis 2007; 24:109-14. [PMID: 17294139 DOI: 10.1007/s11239-007-0012-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/24/2006] [Accepted: 01/18/2007] [Indexed: 10/23/2022]
Abstract
BACKGROUND No-reflow developed after coronary revascularization is an independent predictor of in-hospital mortality and poor clinical outcome. In this study, we investigated the difference between direct stenting and stenting with predilation, regarding to development of no-reflow in patients with acute coronary syndromes (ACS) and the role of fibrinolytic system in that phenomenon. METHODS Fifty eight patients with the diagnosis of ACS in whom percutaneous coronary intervention (PCI) was applied were included in study. Patients were divided into two groups according to stent application with and without predilation. Pre- and post-intervention corrected TIMI frame counts (cTFC) were calculated. Post-PCI plasminogen activator inhibitor-1 (PAI-1), tissue plasminogen activator (tPA), plasminogen and D-Dimer levels were measured. RESULTS Pre-intervention cTFC values were similar between stenting with and without predilation groups (P > 0.05). There was a significant decrease in post-intervention cTFC values in both groups (P < 0.002 and P < 0.05, respectively). But, there was no significant difference between post-intervention cTFC values of the groups, regardless to stent implantation techniques. (P > 0.05). In patients having high cTFC values compared with having low cTFC values; PAI-1 (P = 0.002), tPA (P = 0.015), plasminogen (P = 0.040) and D-dimer (P = 0.049) levels were significantly higher. Also, significant relationship was determined between cTFC and PAI-1, tPA, plasminogen, D-dimer levels (P values 0.003, <0.05, <0.05, and <0.002, respectively). CONCLUSIONS Results of this study indicated an important role of increased fibrinolytic activity in development of no-reflow phenomenon after PCI. We didn't observe any differences between direct stenting and stenting with predilation according to the occurrence of no-reflow.

Effect of glucose-insulin-potassium infusion on myocardial damage due to percutaneous coronary revascularization. Am J Cardiol 2005; 96:1517-20. [PMID: 16310433 DOI: 10.1016/j.amjcard.2005.07.060] [Citation(s) in RCA: 17] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2005] [Revised: 07/07/2005] [Accepted: 07/07/2005] [Indexed: 11/28/2022]
Abstract
Percutaneous coronary intervention has been known to cause myocardial damage as a result of microvascular dysfunction due to microembolization and microinfarction. Previous studies have shown that glucose-insulin-potassium (GIK) infusion decreases mortality in patients with acute myocardial infarction. Therefore, in this study, we aimed to investigate the effect of GIK infusion on myocardial damage due to percutaneous coronary revascularization. A total of 52 consecutive nondiabetic patients diagnosed with non-ST-elevation acute coronary syndrome and designated for elective percutaneous coronary intervention were randomized in a double-blind fashion into GIK and normal saline groups. GIK infusion (30% dextrose, 300 U insulin, and 60 mEq potassium chloride) at a dose of 1.5 ml/kg/hour was initiated 24 hours before the intervention and continuing during and until 1 hour after the intervention. Troponin I levels were recorded in venous blood samples before and 12 and 24 hours after the intervention. The increase in troponin I was significantly lower at 12 and 24 hours in the GIK group compared with those of the saline controls (p=0.022 and p=0.005, respectively). GIK infusion initiated 24 hours before coronary stenting for non-ST-elevation acute coronary syndrome resulted in less myocardial damage as determined by postprocedure troponin I levels.

Abstract
BACKGROUND The relationships among troponin concentration, early phase coagulation activation and soluble P-selectin concentration was evaluated in this study. METHODS AND RESULTS Troponin-l, soluble P-selectin, von Willebrand factor (vWF), fibrinogen, plasminogen, plasminogen activator inhibitor 1 (PAI-1) and tissue plasminogen activator (t-PA) concentrations of 202 consecutive patients with non-ST elevation acute coronary syndrome (NSTE-ACS) were measured at the time of admission. Patients were classified into 2 groups as troponin-negative (<0.2 ng/ml, n=129) or positive (>or=0.2 ng/ml, n=73). Soluble P-selectin concentrations were found to be higher (p<0.001) and correlated with troponin concentrations (r=0.313, p<0.005) in troponin-positive patients with NSTE-ACS. In these patients fibrinogen (p<0.001), plasminogen (p<0.001) and PAI-1 (p<0.026) concentrations were higher and t-PA concentrations were lower (p<0.013) and all these parameters correlated with P-selectin concentrations (p<0.001). There was no difference between the groups according to vWF concentrations (p=0.379). Soluble P-selectin concentrations were found to be an independent predictor of troponin positivity (beta=0.295, odds ratio =1.05, p<0.001). Analysis of regression revealed a significant effect of troponin on soluble P-selectin concentrations (r=0.52, r2=0.27, p<0.001). CONCLUSIONS The results suggest that higher soluble P-selectin concentrations might be involved in increased coagulation activation and myocardial injury development in patients with NSTE-ACS.

Abstract
Left ventricular diverticulum is a rare congenital anomaly. In the adult population, the incidence was reported to be 0.26% in nonselected patients who underwent cardiac catheterization. Diverticula are usually localized near the apex and most often involve the inferior or anterior parietal walls of the left ventricle. In this report, two cases with congenital left ventricular diverticulum are presented, and the pathophysiologic, diagnostic, and therapeutic approaches of this cardiac malformation are discussed.

Abstract
Salt-type minerals can be usually floated with either anionic or cationic collectors. In a number of systems, flotation has been reported to remarkably increase above the concentrations where precipitation of the collector salt is initiated. Some studies attribute this phenomenon to heterocoagulation of oppositely charged colloidal precipitate and mineral particles. In this study, ulexite, a semisoluble boron mineral, in the presence of various multivalent ions, i.e. Ba2+, Mg2+, Ca2+, and Al3+, was found to exhibit excellent flotation even when particles, colloidal precipitates, and bubbles acquire a similar charge, which indicates that attractive structural forces exceed the forces of electrostatic repulsion.
