Abstract
Systemic sclerosis is a chronic, autoimmune, multisystem disease characterized by vascular dysfunction, chronic inflammation and widespread fibrosis. Although vascular involvement commonly manifests in the skin, it can also affect other organs, including the eyes. The characteristic vascular alteration is an obliterative fibroproliferative vasculopathy leading to hypoxia and tissue ischemia. We present a case of bilateral macular edema in a patient diagnosed with systemic sclerosis, as a consequence of retinal and choroidal vascular changes.

Abstract
A 51-year-old non-obese woman presented with a one-week history of progressive blurry vision within the inferior visual field of her left eye. Her only relevant past medical history was long-standing hypothyroidism and recent vaccination against Coronavirus Disease 2019 (COVID-19) with an mRNA vaccine 12 days before the onset of symptoms. At examination, the anterior segment was unremarkable, but the retinal fundus revealed a central retinal vein occlusion associated with a branch retinal artery occlusion of the superior temporal branch in her left eye. Ancillary tests to rule out thrombophilia, hyperviscosity, hypercoagulability, or inflammation were negative. Ultrasound tests were also negative for a cardiac or carotid origin of the branch retinal artery occlusion. At two-month follow-up, no new retinal vascular occlusive events were observed. Although the best-corrected visual acuity at presentation was 8/10 in the left eye, the final best-corrected visual acuity remained 3/10.

Abstract
BACKGROUND Neisseria gonorrhoeae (NG) isolates with high-level azithromycin resistance (HL-AziR) have emerged worldwide in recent decades, threatening the sustainability of current dual-antimicrobial therapy. OBJECTIVES This study aimed to characterize the first 16 NG isolates with HL-AziR in Barcelona between 2016 and 2018. METHODS WGS was used to identify the mechanisms of antimicrobial resistance, to establish the MLST ST, NG multiantigen sequence typing (NG-MAST) ST and NG sequence typing for antimicrobial resistance (NG-STAR) ST and to identify the clonal relatedness of the isolates with other closely related NG previously described in other countries based on a whole-genome SNP analysis approach. The sociodemographic characteristics of the patients included in the study were collected by comprehensive review of their medical records. RESULTS Twelve out of 16 HL-AziR isolates belonged to the MLST ST7823/NG-MAST ST5309 genotype and 4 to MLST ST9363/NG-MAST ST3935. All presented the A2059G mutation in all four alleles of the 23S rRNA gene. MLST ST7823/NG-MAST ST5309 isolates were only identified in men who have sex with women and MLST ST9363/NG-MAST ST3935 were found in MSM. Phylogenomic analysis revealed the presence of three transmission clusters of three different NG strains independently associated with sexual behaviour. CONCLUSIONS Our findings support the first appearance of three mild outbreaks of NG with HL-AziR in Spain. These results highlight the continuous capacity of NG to develop antimicrobial resistance and spread among sexual networks. The enhanced resolution of WGS provides valuable information for outbreak investigation, complementing the implementation of public health measures focused on the prevention and dissemination of MDR NG.

Abstract
OBJECTIVE To compare the efficacy of infliximab (IFX) versus adalimumab (ADA) as a first-line biologic drug over 1 year of treatment in a large series of patients with refractory uveitis due to Behçet's disease (BD). METHODS We conducted an open-label multicenter study of IFX versus ADA for BD-related uveitis refractory to conventional nonbiologic treatment. IFX or ADA was chosen as the first-line biologic agent based on physician and patient agreement. Patients received 3-5 mg/kg intravenous IFX at 0, 2, and 6 weeks and every 4-8 weeks thereafter, or 40 mg subcutaneous ADA every other week without a loading dose. Ocular parameters were compared between the 2 groups. RESULTS The study included 177 patients (316 affected eyes), of whom 103 received IFX and 74 received ADA. There were no significant baseline differences between treatment groups in main demographic features, previous therapy, or ocular sign severity. After 1 year of therapy, we observed an improvement in all ocular parameters in both groups. However, patients receiving ADA had significantly better outcomes in some parameters, including improvement in anterior chamber inflammation (92.31% versus 78.18% for IFX; P = 0.06), improvement in vitritis (93.33% versus 78.95% for IFX; P = 0.04), and best-corrected visual acuity (mean ± SD 0.81 ± 0.26 versus 0.67 ± 0.34 for IFX; P = 0.001). A nonsignificant difference was seen for macular thickness (mean ± SD 250.62 ± 36.85 for ADA versus 264.89 ± 59.74 for IFX; P = 0.15), and improvement in retinal vasculitis was similar between the 2 groups (95% for ADA versus 97% for IFX; P = 0.28). The drug retention rate was higher in the ADA group (95.24% versus 84.95% for IFX; P = 0.042). CONCLUSION Although both IFX and ADA are efficacious in refractory BD-related uveitis, ADA appears to be associated with better outcomes than IFX after 1 year of follow-up.

Abstract
PURPOSE To investigate the seasonal influence on the incidence of uveitis attacks. METHODS An ecological study was designed including 731 uveitis attacks in 594 patients diagnosed at the eye emergency of a hospital in Madrid between 2014 and 2017. The incidence of uveitis attacks, B27+, and presumed herpetic attacks were calculated, and their correlations with seasonal and environmental variables in the same timeframe were analyzed. The analyzed variables were precipitation, barometric pressure, temperature, humidity, wind speed, global solar radiation, ultraviolet radiation, air pollution components (particulate matter and polluting gases), and the incidence of influenza. RESULTS The incidence of attacks was significantly higher in the winter than in the autumn (p = .025). It showed a significant correlation to the number of rainy days per month (r = 0.612;p = .04), and the average wind speed (r = 0.469;p = .02) after Bonferroni correction. CONCLUSION Uveitis episodes happened more frequently under rainy and windy conditions. Most factors were not significantly correlated to attacks.

Abstract
The definition of the negative response of the full field electroretinogram is the presence of a b-wave with less amplitude than the a-wave (b/a ratio<1) in the combined response of cones and rods. The presence of this pattern reflects an alteration in the bipolar cells, the Müller cells, or in the transmission of the stimulus from the photoreceptors to the bipolar cells, with preserved photoreceptor function. This finding can be seen bilaterally and symmetrically in different hereditary conditions, such as congenital stationary night blindness, juvenile X-linked retinoschisis, and Duchenne and Becker muscular dystrophies. On the other hand, it can also be found unilaterally (or asymmetrically) in acquired pathologies, such as some types of immuno-mediated retinitis (Birdshot retinochoroiditis), autoimmune retinopathies, cancer/melanoma associated retinopathy, or retinal toxicity. The objective of this review is to summarise the characteristics of the pathologies in which this finding can be observed, in order to highlight its usefulness in the differential diagnosis of retinal conditions.

Abstract
Wet wrap therapy (WWT) consists of topical steroids administered under a layer of wet cotton bandages or garments. Several trials with WWT have reported promising results in atopic dermatitis (AD). However, no systematic review and meta-analysis on its efficacy and safety has been published. Our objective was to conduct a systematic review of the literature on WWT in AD to assess its efficacy and safety. We included randomized controlled trials among patients of all ages with a diagnosis of AD based on predefined criteria or made by a dermatologist. Electronic searches were performed from 1970 to 30 March 2016 in the Cochrane Central Register of Controlled Trials, MEDLINE, Embase and the World Health Organization International Clinical Trials Registry. Selection of studies and data extraction were performed independently by two researchers, and discrepancies were resolved by consensus. Six trials comparing WWT with topical steroids in children or adults with AD were included. Sample sizes ranged from 19 to 51 patients. Results on clinical severity and quality of life were reported incompletely and proved heterogeneous across studies. A nonsignificant tendency to increased risk of mild skin infections was observed in those treated with WWT (pooled relative risk 6·35, 95% confidence interval 0·83-48·55). The overall grade of quality of evidence for the efficacy and safety outcomes was low. In conclusion, the evidence that WWT is more effective than conventional treatment with topical steroids in AD is of low quality. Further clinical trials should establish the efficacy of WWT in AD.

Abstract
CASE REPORT A 14 year-old boy attended our clinic complaining of a scotoma after an accidental exposure to a 10W, 450nm laser beam from a blue-light handheld laser device. Optical coherence tomography confirmed a full thickness macular hole. As visual acuity (VA) remained 20/20 Snellen, observation was decided. Spontaneous closure was confirmed after one month. DISCUSSION Reckless use of high-power handheld laser devices may induce severe retinal lesions, including full thickness macular holes. Observation is a sensible treatment option in this type of macular hole, especially when VA is preserved. The pathophysiology of these cases differs from senile full thickness macular holes.

Abstract
PurposeTo assess the efficacy of small-gauge vitrectomy with subretinal recombinant tissue plasminogen activator (rtPA) and ranibizumab for submacular haemorrhages secondary to neovascular age-related macular degeneration (nAMD), and to identify the factors associated with visual outcome.MethodsA retrospective case series was performed, including all patients who had small-gauge vitrectomy with subretinal rtPA and ranibizumab for submacular haemorrhages secondary to nAMD. All patients received three consecutive monthly injections of ranibizumab after the surgery, and were reviewed monthly and treated on a pro re nata regime.ResultsA total of 45 eyes of 45 patients were included in the study. Mean age was 77.07±9.67 years, and 32 of 45 patients (71.1%) were women. Surgery was performed on average 6.98±5.70 days after the onset of symptoms, and patients were observed for a follow-up period of 12.9±10.8 months. On average, visual acuity improved -0.59±0.61 LogMAR between presentation and last follow-up. Visual acuity improved in 33 patients (73.3%), remained unchanged in 10 patients (22.2%), and worsened in 2 patients (4.4%). Multiple linear regression showed that patients with smaller haemorrhages (P=0.012) and prompt surgery (P=0.008) had better final visual acuities. A haemorrhage area of ≤30 mm(2) had 91.3% sensitivity and 73.3% specificity for predicting a final visual acuity ≥6/60.ConclusionSmall-gauge vitrectomy with subretinal rtPA and ranibizumab is effective for improving visual acuity in patients with submacular haemorrhages secondary to nAMD. Small haemorrhage area and prompt surgery are associated with better final visual acuity.

Abstract
CASE REPORT A 46 year-old man was seen in the emergency department complaining of vision loss and exophthalmos in his right eye. He also complained of headache, diplopia of 4 months onset, and neurosensory detachment that resolved spontaneously the month before. The study revealed tortuous conjunctival and episcleral vessels and neurosensory macular detachment in his right eye. A carotid-cavernous fistula was confirmed by computed tomography angiography. The fistula closed spontaneously during the hospitalization. One month later, the neurosensory detachment disappeared again. DISCUSSION Carotid-cavernous fistula should be included in the differential diagnosis of neurosensory macular detachments. These neurosensory detachments can resolve spontaneously 11 the fistula is closed.

Abstract
OBJECTIVE To determine the incidence and the risk factors involved in the development of the three main postoperative capsular complications: posterior capsule opacification (PCO), capsular bag distension syndrome (CBDS), and anterior capsular phimosis syndrome (ACP). SUBJECTS, MATERIAL AND METHODS A retrospective cohort study was conducted on 801 patients submitted to cataract surgery in the ophthalmology unit of Hospital del Henares (Madrid) from March 2, 2009 to February 28, 2010. Computerized clinical charts were reviewed during July 2012. PCO was studied using the Kaplan-Meier method (log rank test). RESULTS A total of 167 patients developed PCO. No association could be demonstrated between PCO and age, sex, diabetes mellitus, phaco technique, IOL model, tamsulosin intake, glaucoma, and age-related macular degeneration. Three patients developed CBDS, all of them have received and Akreos Adapt AO(®) (Bausch & Lomb). Two of them were young men who had received surgery for posterior subcapsular cataracts. Three patients developed ACP, 2 of whom had received a MicroSlim(®) IOL (PhysIOL). CONCLUSIONS No association was found between PCO and any of the studied variables. Male gender, young age, subcapsular cataract and large non-angulated lens such as Akreos Adapt AO(®) could be associated with CBDS. ACP could be more frequent when microincision IOLs (like MicroSlim(®)) are implanted.

Abstract
The objective of this review is to describe the clinical and epidemiological characteristics of adenoviral conjunctivitis, as well as to present a practical update on its diagnosis, treatment and prophylaxis. There are two well-defined adenoviral keratoconjunctivitis clinical syndromes: epidemic keratoconjunctivitis and pharyngoconjunctival fever, which are caused by different adenovirus serotypes. The exact incidence of adenoviral conjunctivitis is unknown. However, cases are more frequent during warmer months. Contagion is possible through direct contact or fomites and the virus is extremely resistant to different physical and chemical agents. The symptomatology of conjunctival infection is similar to any other conjunctivitis, with a higher incidence of pseudomembranes. In the cornea, adenoviral infection may lead to keratitis nummularis. Diagnosis is mainly clinical, but its etiology can be confirmed using cell cultures, polymerase chain reaction or immunochromatography. Multiple treatments have been tried for this disease, but none of them seem to be completely effective. Prevention is the most reliable way to control this contagious infection.

Abstract
The purpose of this investigation was to determine the prevalence of plasmid-mediated AmpC (pAmpC) and carbapenemases in Enterobacteriaceae collected from 35 hospitals in Spain and to establish their epidemiological relationships. We conducted a prospective multi-centre study on pAmpC- or carbapenemase-producing Enterobacteriaceae isolates from clinical samples collected from February to July 2009. The strains suspected to carry pAmpC were resistant or showed intermediate susceptibility to co-amoxiclav and second- or third-generation cephalosporins. Strains suspected to carry a carbapenemase were selected because they showed a minimum inhibitory concentration (MIC) to imipenem >1 mg/L. Polymerase chain reaction (PCR) and a sequencing strategy were used to characterise the enzymes. The clonal relationships between isolates was analysed by pulsed field gel electrophoresis (PFGE). Among 100,132 Enterobacteriaceae isolates collected, 1,654 were compatible with the production of pAmpC or carbapenemases. We found a prevalence of 0.64 % of pAmpC (n = 635) and 0.04 % of carbapenemases (n = 43). The most prevalent pAmpC enzymes were CMY-type (78.3 %), DHA-type (19.5 %), ACC-type (1.6 %) and FOX-type (0.6 %). The CMY-type was the most frequent in Escherichia coli and Proteus mirabilis species, whereas the DHA-type was mainly found in Klebsiella spp. The enzymes involved in carbapenem resistance were VIM-1, IMP-22 and the new IMP-28. Nine new bla genes were described: bla (CMY-54), bla (CMY-55), bla (CMY-56), bla (CMY-57), bla (CMY-96), bla (DHA-6), bla (DHA-7), bla (FOX-8) and bla (IMP-28). The prevalence of pAmpC or carbapenemases found is not negligible. The CMY-types were the predominant pAmpC, whereas the VIM or IMP enzymes were the predominant carbapenemases. Furthermore, we observed a great genetic diversity among pAmpC-producing strains and a close clonal relationship between carbapenemase-producing strains.

Abstract
We describe a case of maculopathy consisting of macular retinoschisis and serous macular detachment occurring in a patient with an acquired enlarged optic disc cup, similar to the maculopathy observed in congenital optic nerve abnormalities, mainly optic nerve pits and colobomas, without vitreomacular traction nor angiographic leak. Pars plana vitrectomy with argon laser endophotocoagulation and gas tamponade was found to be useful. Traction from membranes covering deep optic disc cups may create small retinal dehiscences, as described in congenital optic nerve abnormalities, which will enable the liquefied vitreous to pass, leading to retinoschisis with or without associated neurosensory detachment. Vitrectomy, photocoagulation, and gas tamponade may be a useful therapy for this entity.

Abstract
Listeriosis is a resurgent foodborne disease in European countries. Benefits of combined β-lactam-aminoglycoside treatment remain controversial and the impact of the underlying disease on prognosis has not been fully assessed. We conducted a retrospective review of cases of sporadic listeriosis in adults from 1995 to 2008 at two university-affiliated hospitals serving a population of 600,000 people in Madrid, Spain. The primary end-point was the associated in-hospital mortality. Sixty-four patients were studied. Estimated incidence of listeriosis was 0.76/100.000 persons/year. Seventy-four per cent had chronic underlying diseases; cirrhosis of the liver and haematological and solid neoplasias were the most common comorbidities. Primary bacteraemia (58%) and meningitis (42%) were the most frequent manifestations. Focal infections were seen in ten cases. In-hospital mortality was 31%. Patients treated with ampicillin or with an ampicillin-gentamicin combination did not differ in age, severity of underlying disease or type of presentation. Differences in mortality were not seen between patients treated with monotherapy and those given combined treatment (28% vs 35%; p 0.634). Ten patients were treated with trimethoprim-sulfamethozaxole alone and only one died. All patients without comorbidities survived infection but mortality of patients with cirrhosis of the liver was 21% and that of patients with haematological or solid neoplasias was 66%. Only haematological neoplasia (OR 6.67; 95% CI 1.71-26.04; p 0.006) was significantly associated with an increased risk of mortality (R(2) (Cox-Snell) = 0.262). Mortality of listeriosis mainly depended on the severity of the underlying disease. Combined ampicillin-gentamicin therapy did not improved survival. Trimethoprim-sulfamethozaxole may be an effective alternative therapy for listerial infections.

Abstract
This study reports on the level of knowledge about correct blood pressure (BP) measurement procedures among 175 third-year and 176 sixth-year students at a medical faculty and 58 third-year students at a nursing college. Only 51.8% of all students thought that they knew how to measure BP correctly (28.6% in the third year and 61.9% in the sixth year at the medical faculty and 91.4% at the nursing college). Among sixth-year medical students, 12.5% knew the appropriate cuff size, 35% that the stethoscope diaphragm should not be placed under the cuff, and 43% that the cuff deflation rate affects BP measurement. Among nursing students, 33% knew the appropriate cuff size, 22% that an outpatient's BP should be measured more than once during each visit, and 55% that a diagnosis of hypertension can only be made if the BP is elevated on more than one visit.

Abstract
AIMS Vibrio populations in the seawater supply and the water of seven exhibition aquaria that simulate various Mediterranean and tropical ecosystems were compared. The similarity of Vibrio populations in the intestine of various fish species, feed and water was examined. Resistance to the antibiotics used in fish health management was analysed for the dominant Vibrio isolates. METHODS AND RESULTS Samples were collected for 1 year from seven exhibition tanks reproducing different ecosystems. The diversity and population similarity among vibrios were determined using a miniaturized biochemical phenotyping method. Similar Vibrio populations were found in the water supply and in the water of the Mediterranean ecosystems. However, different Vibrio populations were found in the water of tanks with tropical ecosystems. Vibrio populations in the water seemed to have a greater effect on the composition of intestinal Vibrio populations than those in feed. No resistance to antibiotics was observed, indicating their appropriate use for health management. CONCLUSIONS Water characteristics have a greater impact on the composition of Vibrio populations in aquaria and fish intestinal microbiota than bacteria in feed. SIGNIFICANCE AND IMPACT OF THE STUDY The microbiological monitoring water could provide valuable information for managing the health of exhibition aquaria.

Abstract
OBJECTIVES To evaluate the presence of qnr genes among enterobacterial isolates carrying extended-spectrum beta-lactamases (ESBLs) in Barcelona, Spain. METHODS Screening for the qnrA, qnrB and qnrS genes was carried out by PCR amplification with specific primers in 305 non-duplicate, clinically relevant ESBL-producing enterobacterial isolates obtained from February 2003 to August 2004. ESBLs from all qnr-positive isolates were characterized by isoelectric focusing, PCR amplification and DNA sequencing. Plasmid analysis was performed by S1 digestion and hybridization with specific probes for the qnr and bla genes. Plasmids containing qnr genes were transferred by conjugation or transformation. The genetic environment of qnrA1 in selected isolates was characterized by cloning experiments. RESULTS Fifteen isolates, each from a different individual, carried qnr. Among them, 14 had qnrA1 (6 Klebsiella pneumoniae, 6 Enterobacter cloacae and 2 Escherichia coli isolates) and 1 had qnrS1 (K. pneumoniae). None of the isolates carried qnrB. Among the qnrA1-carrying isolates, 10 possessed both bla(CTX-M-9) and bla(SHV-12), 2 had both bla(CTX-M-9) and bla(SHV-92) and 2 had bla(CTX-M-9) alone. The isolate with qnrS1 possessed bla(SHV-12). The qnrA1 and ESBL genes were located together on plasmids ranging in size from 40 to 320 kb. qnrS1 and bla(SHV-12) were not located on the same plasmid. Transfer of quinolone resistance was successfully achieved from all but three isolates. The cloned region surrounding qnrA in two K. pneumoniae isolates revealed a novel genetic organization. CONCLUSIONS The prevalence of qnr among enterobacterial clinical isolates carrying ESBLs between 2003 and 2004 in Barcelona was 4.9%. qnrA1 was the most prevalent, whereas only one qnrS and no qnrB were detected.

Abstract
Resistance to beta-lactams and quinolones in two isogenic Enterobacter cloacae isolates was studied. One was susceptible to cefoxitin and amoxicillin-clavulanate. The other one showed its natural beta-lactam resistance pattern. Both isolates had a nonfunctional AmpR regulator. However, within the second one, the presence of a plasmid carrying ampR and qnrA1 allowed reversion to the wild-type beta-lactam resistance phenotype and decreased susceptibility to fluoroquinolones.
