Syphilis is also known as 'the great imitator' for its ability to mimic many diseases due to its extensive range of clinical manifestations. This review aims to provide an update on the clinical presentation, diagnosis and treatment of ocular syphilis. It manifests in a spectrum of ways that can occur at any stage of the disease, and may be the only presenting feature of systemic syphilis, with the most common finding being panuveitis. The diagnosis is usually aided by serology testing: nonspecific treponemal antibodies (for screening and follow-up) and specific treponemal antibodies for confirmation of the diagnosis. The treatment for ocular syphilis is similar to neurosyphilis and includes intravenous aqueous crystalline penicillin.

The COVID-19 outbreak has led to the rapid development and administration of the COVID-19 vaccines worldwide. Data about the immunogenicity and adverse effects of the vaccine on patients with systemic autoimmune rheumatic diseases (SARDs) is emerging.To evaluate Pfizer/BioNTech (BNT162b2) mRNA-based vaccine second-dose immunogenicity and safety, and the relation between them, in patients with SARDs.A total of one hundred forty tow adults who received two doses of the BNT162b2 vaccine were included in the study. The SARDs group included Ninety-nine patients and the control group (forty-three participants) comprised a mixture of healthy participants and patients who were seen at the rheumatology clinic for non-SARDs. Anti-SARS-CoV-2 IgG antibodies against the Spike protein were evaluated using a SARS-CoV-2 IgG immunoassay. A level of 150 AU/mL was considered positive. An adverse effects questionnaire was given to the participants upon their first visit to the clinic after their BNT162b2 vaccination.Of the 142 participants, 116 were seropositive (81.7%) and 26 (18.3%) were seronegative. Of the seronegative participants, 96.2% were SARDs patients. The proportion of seropositivity in the SARDs patients treated with any immunosuppressant was significantly lower (69.9%) compared to the control group and SARDs patients not receiving immunosuppressants (96.8%). A significant negative correlation between seronegativity and treatment with rituximab, mycophenolate mofetil (MMF), and prednisone was found in the SARDs group (p = 0.004, 0.044, 0.007 respectively). No fever was observed following the BNT162b2 vaccine in seronegative patients, and the frequency of musculoskeletal adverse effects upon the second dose of the BNT162b2 vaccine was significantly higher in seropositive compared to seronegative patients and in the control group compared to the SARDs patients (p = 0.045, p = 0.02 respectively).A decline in the immunogenicity to the second dose of BNT162b2 mRNA is seen in patients with SARDs, especially in patients treated with rituximab, MMF, and prednisone. Adverse effects of the vaccine including fever and musculoskeletal symptoms might be a signal for the acquisition of immunity in those patients.• BNT162b2 mRNA vaccine is less immunogenic in SARDs patients compared to the control group. • Rituximab, prednisone, and mycophenolate mofetil significantly reduced immunogenicity to the vaccine. • There is a correlation between immunogenicity and adverse effects of the vaccine.

To investigate the efficacy and safety of 1% rimexolone ophthalmic suspension in children with chronic anterior uveitis under real-life conditions in a tertiary center.This is a retrospective longitudinal study. Medical records were analyzed at baseline, 1, 3, 6 and 12 months before and after switching to rimexolone for best-corrected visual acuity (BCVA), oral steroid use, number of flares, IOP and anti-glaucoma management.Twenty-four patients (41 eyes) diagnosed with either anterior uveitis (n = 25, 60.0%) or panuveitis (n = 16, 40%) were enrolled. The mean age was 10.5 years (4-16 years). The number of patients requiring oral prednisolone reduced from 8 patients (32.0%) at baseline to 3 patients (20.0%) at 12 months (P 0.001). Following baseline, the median number of uveitis flares reduced from 2.0 (inter-quartile range (IQR) 1.0-2.75) to 1.0 (IQR 0.0-1.0) compared to the 12 months before baseline (P 0.001). The mean IOP reduced from baseline (22.0 ± 7.3 mmHg) to 1 month (18.8 ± 8.7 mmHg, P = 0.01) and remained stable up to 12 months (15.9 ± 5.0 mmHg, P 0.001). Average BCVA, dose of oral prednisolone and anti-glaucoma treatments did not change compared to the baseline. The development for IOP ≥ 30 mmHg was associated with a known corticosteroid response [odds ratio (OR) 6.8, P = 0.003] and a dose 7.5 mg/day oral prednisolone (OR 4.4, P = 0.033).Rimexolone 1% ophthalmic suspension is an effective and safe topical steroid for pediatric anterior uveitis.

Background: In 2012, a European initiative called Single Hub and Access point for pediatric Rheumatology in Europe (SHARE) was launched to optimise and disseminate diagnostic and management regimens in Europe for children and young adults with rheumatic diseases. Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children and uveitis is possibly its most devastating extra-articular manifestation. Evidence-based guidelines are sparse and management is mostly based on physicians' experience. Consequently, treatment practices differ widely, within and between nations. Objectives: To provide recommendations for the diagnosis and treatment of JIA-associated uveitis. Methods: Recommendations were developed by an evidence-informed consensus process using the European League Against Rheumatism standard operating procedures. A committee was constituted, consisting of nine experienced paediatric rheumatologists and three experts in ophthalmology from Europe. Recommendations derived from a validated systematic literature review were evaluated by an Expert Committee and subsequently discussed at two consensus meetings using nominal group techniques. Recommendations were accepted if >80% agreement was reached (including all three ophthalmologists). Results: In total, 22 recommendations were accepted (with >80% agreement among experts): 3 on diagnosis, 5 on disease activity measurements, 12 on treatment and 2 on future recommendations. Conclusions: The SHARE initiative aims to identify best practices for treatment of patients suffering from JIA-associated uveitis. Within this remit, recommendations for the diagnosis and treatment of JIA-associated uveitis have been formulated by an evidence-informed consensus process to suggest a standard of care for JIA-associated uveitis patients throughout Europe. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Background The yield of imaging in Horner syndrome has been explored only in children. This study evaluates the yield of imaging in adults. Methods This was a retrospective cohort study of 52 patients with Horner syndrome examined in 2 neuro-ophthalmology hospital clinics. Patients were divided into 3 groups according to the ability to determine the etiology at the time of the first neuro-ophthalmology consultation: group I, etiology of Horner syndrome known at the initial neuro-ophthalmologic examination; group II, etiology of Horner syndrome not known at the initial neuro-ophthalmologic examination, but sufficient information obtained to allow targeted imaging; and group III, etiology of Horner syndrome not known at the initial neuro-ophthalmologic examination, and sufficient information not obtained to allow targeted imaging. The yield of investigation and the frequency of the different etiologies were evaluated. Results In 32 (62%) patients, the etiology was already known at the initial neuro-ophthalmologic examination (group I). The most prevalent etiology was surgical trauma. In 11 (21%) patients, a targeted imaging workup was possible, revealing an etiology in 7 patients (group II). Carotid dissection and cavernous sinus mass were the most common etiologies. In 9 (17%) patients, a nontargeted imaging evaluation was necessary, revealing an etiology in only 1 patient, who had a previously undetected thyroid malignancy (group III). Conclusions The etiology of Horner syndrome is usually known at the time of initial presentation to a neuro-ophthalmologist. When the etiology is not known and clinical information permits a targeted imaging evaluation, an etiology can usually be determined, most commonly a cervical carotid artery dissection or a cavernous sinus mass. When the etiology is not known and clinical information is insufficient to allow a targeted imaging evaluation, an etiology is rarely discovered. Even so, nontargeted imaging is warranted because life-threatening lesions, such as thyroid malignancies, may rarely be detected.

Red desaturation is a subjective, sensitive test for patients with optic nerve disease. There is no quantitative clinical test to measure the severity of color desaturation. The current study introduces a simple PowerPoint presentation for quantification of red desaturation in patients with optic neuritis. A Microsoft Office PowerPoint presentation was designed. A red square is shown on each half of the screen. The degree of desaturation on one side is increased in each successive slide. The patient holds a black cardboard divider between his/her eyes, such that each eye can see one-half of the screen. The patient uses the mouse to forward through the slides, thereby gradually increasing the desaturation of the red square presented to the normal eye until it matches the color of the red square seen with the tested eye. Desaturation is graded by the number of slide changes needed until subjective equal color between the eyes is perceived. The test was presented to normal volunteers and to patients with optic neuritis. The difference in saturation levels between the right and the left eyes in patients with optic neuritis vs controls was compared. A total of 83 patients were included. Patients with optic neuritis had significantly increased desaturation compared to controls (6.17 ± 3.3 vs 0.24 ± 2.8 respectively; p

The most common ophthalmologic manifestation of hypertension is hypertensive retinopathy. Our study was designed to evaluate the factors that determine retinal vessel caliber in hypertensive subjects.During a 6-month period, retinal photographs were taken of participants during a routine yearly check-up. The photographs were evaluated by an ophthalmologist and the diameters of the individual retinal vessels were measured and summarized by a computer program. Data including patient's medical history, physical examination and laboratory evaluations were collected. The findings of the ophthalmologic examinations were analyzed with respect to the relevant systemic data.We evaluated 285 subjects (43 women) with an average age of 62 ± 9 years (range 33-87). Hypertension was reported in 204 (71.6%) subjects and diabetes mellitus in 60 subjects (21%). The arteriolar calibers were inversely related to age (R = - 017; p = 0.01). Retinal arteriolar and venular calibers were wider in smokers and in subjects with dyslipidemia. History of hypertension was not associated with any vascular changes. However, retinal arteriolar caliber was inversely related to blood pressure levels. Diuretic treatment was associated with narrow retinal venular caliber.The association between different cardiovascular risk factors and hypertensive retinopathy is complex. Effective blood pressure control has a beneficial effect on the vascular changes in the retina.
