Abstract
PURPOSE This study aimed to determine the changes that occur in the vasculature, as based on optical coherence tomography angiography (OCTA) after non-damaging endpoint management (EpM), using a continuous wave yellow laser. The study was on eyes with diabetic macular edema (DME) that were resistant to anti-vascular endothelial growth factors (anti-VEGFs). MATERIALS AND METHODS This was a retrospective analysis of OCTA images of 44 eyes in 44 patients with DME refractory to anti-VEGF. The eyes were treated with a PASCAL Streamline yellow laser (577 nm wavelength, 200 mm spot size). Treatment was administered to the DME area and utilized 10% continuous wave laser energy and 0.50 µm beam diameter spot spacing. Best-corrected visual acuity (BCVA) and enhanced in-depth imaging with optical coherence tomography (EDI-OCT) and fundus autofluorescence (FAF) images were recorded at baseline, and 3 and 6 months posttreatment. Total choroidal area (TCA), luminal area (LA), stromal area (SA), and the choroidal vascularity index (CVI) were calculated using Image J software. The macula was divided into five quadrants in accordance with the mapping system in the Early Treatment Diabetic Retinopathy Study (ETDRS). RESULTS All patients (mean age: 58.90 ± 9.55 years) were diagnosed with diabetes mellitus type 2. Mean BCVA at baseline was 0.30 ± 0.11 logarithm of the minimum angle of resolution (logMAR) versus 0.23 ± 0.10 logMAR at 3 months (p = 0.032) and 0.17 ± 0.10 logMAR at 6 months (p = 0.013). The foveal avascular zone area (FAZ) decreased in the deep capillary plexus (DCP) from baseline to 6 months (p = 0.028). Vessel densities (VDs) of the superficial capillary plexus (SCP), DCP, and choriocapillaris decreased significantly in the fovea at 3 and 6 months compared to baseline (p < 0.05 for both follow-up time points). There were significant decreases in SCP and DCP in the superior quadrant at the end of month 6 (p = 0.001 and p = 0.038, respectively). There was a significant decrease in the nasal quadrant of the DCP and choriocapillaris at the end of month 6 (p = 0.024 and p = 0.049, respectively). Although there was a significant decrease in central macular thickness (CMT) (p < 0.001), subfoveal choroidal thickness (SFCT) (p < 0.001), and LA (p = 0.034) at months 3 and 6, there was no significant change in the CVI (p = 0.19). According to the DME recovery rate, 36 eyes (81%) were irradiated once, whereas 8 eyes (19%) were irradiated twice. CONCLUSIONS Non-damaging EpM therapy using a continuous wave yellow laser in eyes with DME that are resistant to anti-VEGFs induces significant changes in the SCP, choriocapillaris, and, most commonly, the DCP, which caused a significant decrease in VDs during 6 months of follow-up.

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
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
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
Objectives The aim of this study was to examine the impact of performing surgeries with necessary precautions and to evaluate demographic characteristics of operated patients during novel coronavirus-2019 (COVID-19) pandemic and the infection rates during hospitalization and within 14 days after surgery. Material and Methods Between March 15th, 2020 and April 30th, 2020, a total of 639 patients who had been operated on in our center were retrospectively analyzed. According to the triage system, the surgical procedures were classified as emergency, time-sensitive, and elective procedures. Data including age, sex, indication for surgery, the American Society of Anesthesiologists (ASA) class, pre- and postoperative symptoms, the presence and/ or absence of reverse transcriptase-polymerase chain reaction (RT-PCR) test result, type of surgery, surgical site, and documented COVID-19 infections during hospitalization and within 21 days after surgery were recorded. Results Of the patients, 60.4% were males and 39.6% were females with a mean age of 43.08 ± 22.68 years. Malignancy was the most common indication for surgery (35.5%), followed by trauma (29.1%). The abdominal area and head and neck region were the most frequent surgical sites in 27.4% and 24.9% of the patients, respectively. Of all surgical procedures, 54.9% were emergency and 43.9% were time-sensitive procedures. Of the patients, 84.2% were in ASA Class I-II while 15.8% patients were in ASA Class III, IV and V. General anesthesia was the most common anesthesia type in 83.9% of the patients. The overall rate of COVID-19 infection was 0.63% in the preoperative period. The rate of COVID-19 infection during and after surgery was 0.31%. Conclusion With similar infection rates to the general population, surgeries of all types can be performed safely taking preventive measures in the preand postoperative period. It would be wise to perform surgical treatment without delay in patients with an increased risk for mortality and morbidity in accordance with strict infection control principles.

Abstract
PURPOSE To assess morphological changes and visual results in eyes with pachychoroid neovasculopathy (PNV) that underwent different intravitreal anti-vascular endothelial growth factor (VEGF) agents. MATERIALS AND METHODS This is a retrospective, observational, comparative study included 76 PNV eyes in 76 patients that were allocated to 3 groups according to monotherapy injection procedure, as follows: the intravitreal bevacizumab (IVB) group, intravitreal ranibizumab (IVR) group, and intravitreal aflibercept (IVA) group. Central macular thickness (CMT), best-corrected visual acuity (BCVA), and subfoveal choroidal thickness (SFCT) were measured at baseline, after treatment 1st month, 3rd month, 6th month, and 12th month, and at the final post-treatment examination. RESULTS Mean age of the patients was 57.31 ± 5.91 years (range: 34-67 years). Mean duration of follow-up was 31.50 ± 12.91 months (range: 13-60 months). The IVB group included 30 eyes, the IVR group included 22 eyes, and the IVA group included 24 eyes. There weren't any significant differences in BCVA changes between the groups at any post-baseline measurement time point. Although CMT did not change significantly in the IVB group from baseline to final follow-up visit (baseline: 376.33 ± 86.31µm; final visit: 340.80 ± 122.70 µm) (p = 0.172), CMT did change significantly in the IVA group (baseline: 383.41 ± 131.83 µm; final visit: 297.33 ± 103.81 µm) (p = 0.029) and IVR group (baseline: 379.18 ± 97.93 µm; final visit: 335.72 ± 111.45 µm) (p = 0.041). SFCT decreased significantly in the IVR and IVA groups (p = 0.015 and p < 0.001, respectively). The mean number of injections was 12.06 ± 4.72 (range: 6-20) in the IVB group, 11.81 ± 3.31(range: 7-17) in the IVR group, and 7.16 ± 3.15 (range: 4-13) in the IVA group (p = 0.004). CONCLUSION All 3 anti-VEGFs were effective in terms of visual results in patients with PNV. Patients treated with IVA required fewer injections than those treated with IVB or IVR. Furthermore, IVR and IVA treatment significantly decreased SFCT, whereas IVB did not.

Abstract
PURPOSE To report a newborn patient with gastrointestinal (GIS) perforation after intravitreal ranibizumab (RBZ) treatment. CASE REPORT The patient was born at 31 gestational week and hospitalized with the diagnosis of small for gestational age and prematurity. In the follow up he underwent GIS surgery due to necrotizing enterocolitis (NEC) and was diagnosed with retinopathy of prematurity (ROP). At 43 weeks of postmenstrual age, he developed intestinal perforation after 12 h of the second low-dose RBZ injection. According to our knowledge, this is the first report of GIS perforation due to low-dose intravitreal RBZ treatment in an infant with severe ROP. CONCLUSION The risk of GIS perforation should be taken into consideration during the application of intravitreal vascular endothelial growth factor antagonist agents, especially in newborns with previous GIS surgery and a history of NEC, and these patients should be carefully monitored for GIS complications.

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
PURPOSE The aim of this study is to compare the efficacy of half-fluence photodynamic therapy (PDT) and half-dose PDT on the choroidal structure via perfusion of the retinal plexus and choriocapillaris in eyes with chronic central serous chorioretinopathy (cCSCR). MATERIALS AND METHODS This retrospective study included 43 eyes in 43 patients with cCSCR. Patients in group 1 received half-fluence (verteporfin 6 mg m-2) PDT and those in group 2 received half-dose (verteporfin 3 mg m-2) PDT. Enhanced depth imaging optical coherence tomography and optical coherence tomography angiography (OCTA) images were recorded 1 day before and 3 months after PDT. Total choroidal area (TCA), luminal area (LA), and stromal area (SA) were calculated using Image J software. RESULTS From baseline to 3 months post PDT TCA decreased from 2.43 ± 0.47 mm2 to 2.08 ± 0.59 mm2 (p < 0.001), LA decreased from 1.78 ± 0.11 mm2 to 1.54 ± 0.26 mm2 (p < 0.001), and SA decreased from 0.76 ± 0.33 mm2 to 0.53 ± 0.37 mm2 (p < 0.001) in group 1. Choriocapillaris vascular density measured via OCTA increased from 37.82 ± 10.99 at the initial visit to 44.96 ± 15.34 at month 3 after half-fluence PDT administered to the fovea (p < 0.001). Deep capillary plexus vessel density was 32.49 ± 11.36 at baseline and increased to 43.27 ± 11.40 at month 3 after half-fluence PDT administered to the fovea (p < 0.001) in group 1. TCA decreased to 2.00 mm2 ± 0.51 mm2 from 2.39 mm2 ± 0.43 mm2 (p < 0.001), LA decreased to 1.53 ± 0.29 mm2 from 1.74 ± 0.16 mm2 (p = 0.019). Although SA decreased from 0.76 ± 0.33 mm2 to 0.53 ± 0.37 mm2 in group 2, the difference was not significant (p = 0.07). Based on OCTA, choriocapillaris vascular density increased from 43.68 ± 10.38 mm2 at baseline to 47.46 ± 6.42 mm2 at 3 months after half-dose PDT onto the fovea (p = 0.049). Deep capillary plexus vessel density increased from 34.37 ± 9.36 mm2 at the initial visit to 38.17 ± 8.81 mm2 3 months after half-dose PDT onto the fovea (p = 0.046) in group 2. At 3 months, post-PDT subretinal fluid (SRF) was significantly higher resolution in group 1 than in group 2 (p = 0.021). CONCLUSIONS OCTA shows there is a significant increase in deep capillary plexus and choriocapillaris perfusion 3 months after both half-fluence PDT and half-dose PDT. Although there was a significant decrease in LA in both groups, based on OCTA there was a significant decrease in SA, a significant increase in choriocapillaris and deep capillary perfusion in group 1; therefore, the level of SRF resolution at month 3 post PDT might explain its higher incidence in group 1.

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
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
Steroidogenic factor-1 (SF-1), also known as nuclear receptor subfamily 5 group A member 1 (NR5A1), is a member of orphan receptor subfamily and located on chromosome 9 (9q33). In 46, XY individuals with mutation of SF-1 gene, adrenal failure, testis dysgenesis, androgen synthesis defects, hypospadias and anorchia with microphallus, infertility can occur from severe to mild. We report a case of a 20-day-old male who is admitted to our clinic due to ambiguous genitalia. In this report, we describe a novel heterozygous c.814A > C (p. T272P) NR5A1 mutation in a patient with 46, XY DSD without adrenal insufficiency. We describe a novel missense mutation c.814A > C (p. T272P) in NR5A1 gene which had not previously been reported. Also this report highlights that the potential diagnostic utility of next-generation sequencing is an effective strategy versus Sanger sequencing to identify genetic mosaicism in clinical practice.

Abstract
PURPOSE This study aimed to evaluate the changes in macular thickness following inferior oblique muscle recession surgery. MATERIALS AND METHODS Thirty-eight eyes from 21 patients undergoing ocular muscle surgery were included. Patients were grouped into three groups based on the type of surgical intervention: Group I (n = 12), inferior oblique recession surgery alone; Group II (n = 12), inferior oblique plus horizontal muscle surgery; Group III (n = 14), horizontal muscle surgery alone. Each eye was scanned using the optical coherence tomography (OCT) device preoperatively and on the first postoperative day to measure macular thickness. RESULTS Following surgery, a significant increase in foveal thickness occurred in Group I (P < 0.05) and Group II (P < 0.01). In addition, a statistically significant difference was observed between the groups with regard to the increase in foveal thickness (P = 0.016), with significantly lower changes in Group III. CONCLUSION Our findings suggested that inferior oblique muscle recession surgery is associated with an increase in macular thickness.

Abstract
The use of assisted reproductive technologies (ART) has increased gradually in the treatment of infertility worldwide. On the other hand ART has been found to be associated with an increased risk of congenital malformations including imprinting defects as well. Although a number of imprinting syndromes have been reported to be related with ART, no case with uniparental disomy (UPD) caused Prader-Willi syndrome (PWS) [OMIM ID: 176270] has been reported in the literature. Here we present a dizygotic twin in which one of them was born with maternal UPD15 following ART. The proband was a 2-year-old boy who had feeding difficulties, generalized hypotonia, frontal bossing, broad forehead, small hands and feet. Laboratory investigations revealed minimal dilatation in 3rd and 4th ventricles and corpus callosum hypoplasia in magnetic resonance imaging, supravalvular pulmonary stenosis in echocardiography and pelvicaliectasia in the USG examinations. Methylation and microsatellite markers analyses showed maternal UPD for chromosome 15. Here we report, for the first time UPD caused PWS patient born after ART.

Abstract
New array technologies have facilitated the analysis of submicroscopic chromosomal imbalances and structural variants. Copy number variation (CNV) analysis can reveal genetic imbalances in up to 10% of cases involving intellectual disability (ID), with or without multiple congenital anomalies (MCA). Here we present 4 cases, diagnosed by CNV analysis using Affymetrix Genome Wide Human SNP 6.0 array, and their parents. CNVs ranging from 18 to 196 per subject, with a size range of 100kb- 6093kb, were detected in all cases. One case revealed inherited CNVs, whilst de novo ins/dels were found in the other three which may be causative factors in the development of clinical pictures. Microarray technology may help to reveal the etiology of ID and is a potentially useful diagnostic tool for patients with ID/MCA.

Abstract
Caudal appendage is a rare dysmorphic feature of which etiologic mechanisms are not well understood. Here we report monozygotic (MZ) twin brothers who are discordant for the caudal appendage and multiple congenital anomalies. Twins were the product of a 33 weeks of gestation, monochorionic-diamniotic pregnancy. On admission the proband had micrognathia, beaked nose, hypospadias, caudal appendage and juxtaductal aorta coarctation. At birth, he was small for gestational age and he had transient hypothyroidism which was detected in the newborn period. Karyotype analysis showed 46,XY. Monozygosity was shown by 15 microsatellite markers plus amelogenin (AmpFlSTR Identifiler PCR Amplification Kit, Applied Biosystems). Genome-wide copy number analysis of the twins by DNA-DNA hybridization of whole genomic DNA (NimbleGen Human CGH 385K WG-T v2.0 array) showed a significant difference at two neighboring probes with Log2 ratio: 0.72088 which are located on chromosome 3p12.3. Further analysis by high resolution of chromosome 3 array (Roche NimbleGen Human HG18 CHR3 FT Median Probe Spacing 475 bp) and quantitative PCR analysis did not confirm the deletion.

Abstract
Cardio-facio-cutaneous syndrome (CFCS) is a multiple congenital anomaly disorder characterized by craniofacial features, cardiac defects, ectodermal anomalies and neurocognitive delay. Clinical findings of patients with CFCS show similarities to those of patients with Costello Syndrome (CS). CFCS and CS are caused by mutations in genes encoding proteins of the RAS-MAPK signaling pathway. Musculoskeletal findings including tight Achilles tendons and contractures of elbows, shoulders or hips have been reported in CS patients. However, limited extension of joints were observed in some patients with CFCS. According to the literature, no tight Achilles tendons have been reported in CFCS patients so far. In this case report, we present a male CFCS patient with tight Achilles tendons with a de-novo heterozygote N581D mutation in the BRAF gene detected by DNA sequence analysis.

Abstract
Acrocallosal Syndrome is a rare genetic disorder which is characterized by moderate to severe mental retardation, agenesis or hypoplasia of the corpus callosum and polydactyly of fingers and toes. The spectrum of this syndrome is very variable. Prominent forehead, broad nasal bridge, short nose and mandible, hypertelorism, epicanthic folds, large anterior fontanelle and tapered fingers, omphalocele and inguinal hernia are some other common findings in this syndrome. Twenty percent of the patients have associated brain abnormalities such as cerebral atrophy, hypothalamic dysfunction, small cerebrum, micropolygyria, hypoplasia of pons, hypoplasia of cerebellar hemispheres, hypoplasia of medulla oblongata, agenesis or hypoplasia of cerebellar vermis and corpus callosum abnormalities. Here we present a 10-month-old female infant with clinical and radiological findings indicative of acrocallosal syndrome. She was noted to have craniofacial abnormalities suggestive of acrocallosal syndrome, optic atrophy and polydactyly. MRI revealed cerebral atrophy, corpus callosum agenesis, dilated lateral ventricules and unilateral right temporal lobe hypoplasia, the latter not previously reported in the spectrum of this syndrome. Based on this observation we conclude the importance of screening brain abnormalities and present temporal lobe hypoplasia as a new additional anomaly in this syndrome.

Abstract
The prognostic value and the evolution of pulmonary hypertension (PH) in patients with markedly hypoxemic chronic obstructive pulmonary disease (COPD), treated or not with long-term oxygen therapy (LTOT), has been extensively investigated. However, little is known in patients with mildly or moderately hypoxemic COPD not requiring LTOT. Therefore, we assessed the evolution of pulmonary hemodynamics in 131 patients with stable COPD by performing two right heart catheterizations at a mean (+/- SD) time interval of 6.8 +/- 2.9 yr. At inclusion (T0), no patient had PH (i.e., the mean pulmonary artery pressure [Ppa] at rest was < 20 mm Hg). Group 1 included 55 patients without exercising PH and group 2 included 76 patients with exercising PH, defined by a pulmonary arterial pressure (Ppa) > 30 mm Hg during a steady-state 40-W exercise. Group 2 patients compared with group 1 patients had a significantly higher resting Ppa (16 +/- 3 mm Hg versus 14 +/- 2 mm Hg, p = 0.001). At the second catheterization, 33 (25%) patients (9 of 55 in group 1, 24 of 76 in group 2, p = 0.048) showed a resting Ppa > 20 mm Hg, but PH was generally mild, ranging from 20 to 42.5 mm Hg. The mean Ppa at second evaluation was 16 +/- 5 mm Hg in group 1 and 19 +/- 7 mm Hg in group 2 (p = 0.01). The patients who developed resting PH at the second catheterization (T1) had higher resting and exercising Ppa (p = 0.001 and p = 0.002, respectively), and significantly lower resting and exercising Pa(O(2)) (p = 0.005 and p = 0.012, respectively) at T0. Logistic regression analysis showed that resting and exercising Ppa were independent predictors (at T0) for the subsequent development of PH (p = 0.029 and p = 0.027, respectively). The patients who developed resting PH (T1) had a significantly worsening of Pa(O(2)) (from 63.5 mm Hg at T0 to 60 mm Hg at T1, p = 0.047), whereas the Pa(O(2)) as a mean was stable in the remainder (69.5 mm Hg at T0 and T1). These results show the following. The progression of Ppa over time in patients with COPD with mild to moderate hypoxemia is rather slow, the average change for the group as a whole being of + 0.4 mm Hg/yr. Only about 25% of patients with COPD with mild to moderate hypoxemia and without resting PH at the onset will develop PH during a 6-yr follow-up. The patients with exercising PH at the onset have a significantly increased risk of developing PH over time. Only resting and exercising Ppa at the onset are independently related to the subsequent development of PH. However, in individual cases, the models of linear or logistic regression do not allow a pertinent prediction of the level of Ppa or the presence of PH at the second right heart catheterization.
