Risk Factors for Chalazion Diagnosis and Subsequent Surgical Excision.

PURPOSE: To identify factors associated with chalazion diagnosis and surgical excision. METHODS: Patients with an incident chalazion diagnosis from 2002 to 2019 were compared 1:5 with matched controls. Multivariable logistic regression was performed to identify variables associated with diagnosis and surgical excision. RESULTS: Chalazion patients (n = 134,959) and controls (678,160) were analyzed. Risk factors for diagnosis included female sex, non-white race, northeast location, conditions affecting periocular skin and tear film (blepharitis, meibomian gland dysfunction, rosacea, pterygium), non-ocular inflammatory conditions (gastritis, inflammatory bowel disease, sarcoidosis, seborrheic dermatitis, Graves' disease), and smoking (p < .001 for all comparisons). Thirteen percent of patients with chalazion underwent subsequent surgical excision. Diabetes and systemic sclerosis diagnoses decreased odds of diagnosis (p < .001). Male sex, rosacea diagnosis, Black and Hispanic race, antibiotic use, and doxycycline use increased odds of surgery (p < .001). CONCLUSION: Female sex, non-white race, conditions affecting periocular skin and the tear film, several non-ocular inflammatory conditions, and smoking were risk factors for chalazion diagnosis. Male sex, rosacea diagnosis, Black and Hispanic race, antibiotic use, and doxycycline use were risk factors for surgical intervention for chalazion. Our results prompt further study of these variables and their relationship to chalazion diagnosis to understand physiology and improve clinical outcomes. Furthermore, the results of this study suggest early recognition and treatment of concomitant rosacea may serve an important role in the management of chalazion and in the prevention of surgical intervention.

Cryptophthalmos: associated syndromes and genetic disorders.

PURPOSE: Cryptophthalmos is a rare congenital condition caused by anomalous eyelid development where the eyelid folds do not develop or fail to separate. Cryptophthalmos can be unilateral or bilateral and can occur in isolation or as part of an underlying syndrome. We aim to identify genetic syndromes associated with cryptophthalmos to facilitate genetic diagnosis. METHODS: We performed a retrospective medical record review of all patients diagnosed with cryptophthalmos followed at a single center between 2000 and 2020. The analysis included medical history, clinical examination findings, and genetic testing results. RESULTS: Thirteen patients were included, 10 (77%) males, mean age of 2.4 years. Eight (61%) had bilateral cryptophthalmos, and 4 (31%) had complete cryptophthalmos. Associated ocular abnormalities included corneal opacities (13/13, 100%), upper eyelid colobomas (12/13, 92%), and microphthalmia/clinical anophthalmia (3/13, 23%). All cases of complete cryptophthalmos had bilateral disease. An underlying clinical or molecular diagnosis was identified in 10/13 (77%) cases, including Fraser syndrome (n = 5), amniotic band syndrome (n = 1), FREM1-related disease (n = 1), Goldenhar versus Schimmelpenning syndrome (n = 1), MOTA syndrome (n = 1), and CELSR2-related disease (n = 1). CONCLUSION: This is the first report of a possible association between cryptophthalmos and biallelic CELSR2 variants. Children with cryptophthalmos, especially those with extra-ocular involvement, should be referred for comprehensive genetic evaluation.

Cavernous sinus thrombosis with bilateral orbital vein involvement and diffuse ischemic retinopathy / Trombose do seio cavernoso com envolvimento bilateral das veias orbitais e retinopatia isquêmica difusa

ABSTRACT A 53-year-old man with a 3-day history of periorbital swelling and vision loss in the left eye was found to have septic cavernous sinus thrombosis with bilateral orbital vein involvement causing congestive orbitopathy. He was treated with an emergent canthotomy and cantholysis, intraocular pressure-lowering drops, antibiotics, anticoagulation, and serial examinations. Optical coherence tomography ultimately revealed diffuse ischemic destruction of both layers of the retina, which suggested occlusion of the ophthalmic artery or the short posterior ciliary arteries and central retinal artery without intracavernous internal carotid artery involvement. The patient remained without light perception in the left eye after treatment.

RESUMO Um homem de 53 anos, com história de 3 dias de edema periorbital e perda de visão no olho esquerdo, apresentou trombose séptica do seio cavernoso com envolvimento bilateral das veias orbitais, causando uma orbitopatia congestiva. O paciente foi tratado com uma cantotomia e cantólise de emergência, colírios para redução da pressão intraocular, antibióticos, anticoagulantes e exames seriados. A tomografia de coerência óptica finalmente demonstrou destruição isquêmica difusa de ambas as camadas da retina, sugerindo uma oclusão da artéria oftálmica ou das artérias ciliares posteriores curtas e da artéria retiniana central, com ausência de envolvimento do segmento intracavernoso da artéria carótida interna. O paciente permaneceu sem percepção luminosa no olho esquerdo.

Mohs Micrographic Surgery for Facial Merkel Cell Carcinoma.

BACKGROUND: Merkel cell carcinoma (MCC) is a rare malignant cutaneous tumor with frequent metastases. They often appear in the face where cosmetic and functional outcome is critical. Mohs micrographic surgery (MMS) is a controlled intervention that optimizes negative margins without sacrificing tissue. OBJECTIVE: A comprehensive assessment of outcomes of MMS-treated facial MCC will help guide clinicians in surgical and medical management. METHODS & MATERIALS: Retrospective review identified facial MCC cases treated with MMS at a single institution from January 2005 to August 2020. Tumor characteristics and outcomes were recorded and descriptive and predictive analyses were performed. RESULTS: 34 cases were reviewed with a mean followup of 34.4 months. The most common sites were the forehead, cheek-jaw region, and nasal ala. 2 (5.9%) patients had local recurrence by a mean of 4.3 months. No documented variables were significantly associated with local recurrence. 8 (23.5%) patients had progression to metastasis by a mean of 9.4 months. Younger age at biopsy and surgery, male sex, and intraoperative detection of in-transit disease were significantly associated with progression to metastasis. CONCLUSIONS: In summary, the tissue-sparing approach of MMS may be beneficial for MCC in cosmetically and functionally sensitive facial locations as it preserves tissue without compromising outcomes.

Cataracts in setting of multisystem inflammation after COVID-19 vaccination.

Purpose: To describe a unique case of bilateral cataract formation in the setting of multisystem inflammation after the 1st dose of the BNT162b2 mRNA COVID-19 vaccination. Observations: A previously healthy 20-year-old male developed intumescent bilateral cataracts leading to visual decline from 20/20 to 20/300-20/400 in each eye, likely from systemic inflammation after vaccination. Conclusion and importance: This is the first reported case of cataract formation following a COVID-19 vaccine. While ocular adverse effects associated with COVID-19 vaccination are rare, it is important to raise awareness of these entities amongst medical providers as the COVID-19 pandemic continues and vaccinations become widespread.

Orbital and periorbital dermoid cysts: a retrospective analysis of 270 lesions.

PURPOSE: To report the clinical characteristics and intraoperative findings of periorbital and orbital dermoid cysts and their relationship to location and rupture. METHODS: Retrospective review of 270 cases with orbital or periorbital dermoid cysts that presented over a period of 11 years. Patients were included if diagnosis of dermoid cyst was made by histopathologic analysis. Clinical characteristics and operative outcomes were recorded and analyzed with Chi-squared analyses or univariate regression. Multivariate binary logistic regression was performed to assess predictors of location and rupture. RESULTS: Dermoids frequently occurred unilaterally and were more frequently described as mobile (61.5%), followed by fixed (30.8%), and partially fixed (7.7%). Dermoid rigidity was most commonly described as firm (75.5%), followed by cystic, soft, and rubbery. The most common dermoid location was superotemporal (60.4%). On Chi-squared analysis, superotemporal lesions were less likely to have orbital extension than non-superotemporal lesions (OR 0.28, 95% CI: 0.11-0.70, p = .01), less likely to undergo CT (OR 0.16, 95% CI: 0.06-0.41, p < .01) or MRI (OR 0.23, 95% CI: 0.13-0.41, p < .01), more likely to be described as mobile (OR 2.91, 95% CI: 1.32-6.43, p = .01), and less likely to rupture intraoperatively (OR 0.28, 95% CI: 0.11-0.73, p = .01). No variables were associated with rupture in multivariate analysis. CONCLUSION: Superotemporal dermoid cysts are common in the pediatric population, less likely to have orbital extension, undergo imaging, and have intraoperative rupture when compared to other locations in the orbit.

Clinicopathologic Characteristics and Prognostic Factors Impacting Survival in Melanoma of the Eyelid.

PURPOSE: To examine prognostic factors for survival in patients with melanoma of the eyelid. DESIGN: Retrospective cohort study. METHODS: This population-based study reviewed patients with primary melanoma of the eyelid diagnosed in the Surveillance, Epidemiology and End Results database between 1975 and 2016. The primary outcomes included survival rates estimated by Kaplan-Meier analysis and mortality hazard ratios (HRs) for overall survival and disease-specific survival (DSS). RESULTS: The cohort consisted of 2257 patients with cutaneous melanoma of the eyelid, representing 1380 cases of melanoma in situ and 877 cases of invasive melanoma. For melanoma in situ and invasive melanoma respectively, at 5 years, the overall survival rates were 88.6% and 77.1%, while DSS rates were 99.4% and 91.0%. Cox regression analysis for eyelid melanoma indicated that for invasive melanoma, age at diagnosis ≥75 years (HR 2.17 [95% confidence interval {CI} 1.02-4.60]; P = .04), T4 staging (HR 8.45 [95% CI 2.96-25.31]; P < .001), lymph node involvement (HR 3.61 [95% CI 1.12-11.60]; P = .03), and nodular melanoma (HR 3.31 [95% CI 1.50-7.32]; P = .003) histologic subtype were associated with decreased rates of survival. Sex and tumor ulceration did not impact survival. CONCLUSIONS: This study is the largest analysis to date that focuses on DSS for cutaneous melanoma of the eyelid. The most significant predictors for invasive melanoma survival are age ≥75 years at diagnosis, T4 staging, lymph node involvement, and the nodular melanoma histologic subtype. Patients with these attributes are at higher risk and should be counseled regarding prognosis.

Fibroblast Growth Factor Receptor Inhibitor-Associated Multifocal Serous Retinal Detachments: A Case Report.

Purpose: This report aims to describe a case of bilateral, multifocal neurosensory retinal detachments that developed during erdafitinib therapy for metastatic urothelial carcinoma. Methods: A case report with color fundus imaging and spectral-domain optical coherence tomography imaging is presented. Results: A 50-year-old man with metastatic urothelial carcinoma had an unremarkable baseline ophthalmic examination prior to starting erdafitinib. At 3-month follow up, an examination revealed bilateral, multifocal retinal detachments. Because the patient was asymptomatic and erdafitinib was the only drug to which his tumor had responded, he was kept on the medication with close ophthalmic monitoring. Conclusions: Erdafitinib, a fibroblast growth factor receptor inhibitor, can cause bilateral, multifocal retinal detachments. Continuation of erdafitinib may be considered in patients without significant visual impairment when the overall benefit of the medication appears to outweigh the risks.

Board Certification Is Associated With a Reduced Risk of Endophthalmitis After Intravitreal Injections.

Purpose: This work investigates associations between physician qualifications and the risk of postintravitreal injection endophthalmitis. Methods: This retrospective analysis of data from medical claims studied Medicare beneficiaries undergoing 1 or more intravitreal injections between January 1, 2013, and December 31, 2017. Logistic regression analysis was performed to assess whether board certification status or retina subspecialty training was associated with lower risk of postinjection endophthalmitis, controlling for patient's age, race, and sex, type of agent injected, diagnosis, and year of injection. The main outcome measure was odds ratio (OR) of receiving a diagnosis of endophthalmitis in the 14 days after intravitreal injection. Clinical outcome and quality of care were not evaluated in this study. Results: A total of 2 907 324 intravitreal injections were performed on 219 640 patients by 4315 ophthalmologists, 3196 (74%) of whom were retina specialists and 4021 (92%) of whom were certified by the American Board of Ophthalmology (ABO). Overall, there were 1088 (0.037%) cases of postinjection endophthalmitis, of which 1024 (0.037%) were injected by ABO-certified ophthalmologists and 64 (0.050%) by non-board-certified ophthalmologists. Injections by ABO-certified ophthalmologist had 28% reduced odds of endophthalmitis (OR = 0.72; 95% CI, 0.523-0.996, P = .05). Higher odds of endophthalmitis were observed for corticosteroid injections (OR = 3.91; 95% CI, 2.75-5.56, P < .001) and aflibercept injections (OR = 1.47; 95% CI, 1.19-1.80, P < .001). Patients' sex and race, the diagnosis associated with the injection, and providers' retina subspeciality training were not associated with the rate of endophthalmitis (P < .20 for all comparisons). Conclusions: We found evidence that endophthalmitis may be reduced when ABO-certified physicians perform an intravitreal injection.

Comparative Effectiveness of Generic Latanoprost Versus Branded Prostaglandin Analogs for Primary Open Angle Glaucoma.

PURPOSE: The purpose of the study is to determine the comparative effectiveness of generic latanoprost (GL) to its branded (BL) counterpart and other brand-name prostaglandin analogs (bPGAs) in preventing the need for additional therapy in the treatment of primary open angle glaucoma (POAG). METHODS: Retrospective cohort study using US commercial medical claims data. All new POAG patients from 2000 to 2015 who initiated treatment with either GL or BL were included. Exclusion occurred for having less than 2 years of time in the plan prior to diagnosis, previous use of glaucoma medications, or any diagnosis of glaucoma other than POAG at any time. Analyses compared GL to BL and also to those who received any branded PGA after 2011 (when the generic became available). Cox proportional hazard regression was used to assess the hazards of filling a prescription for a second IOP-lowering medication or having surgical intervention, individually and either outcome combined. RESULTS: A total of 6317 and 4150 POAG patients were treated with GL and BL, respectively. After 2010, 6317 GL and 3703 brand-name prostaglandin analog (bPGA) POAG patients met criteria for inclusion. After adjustment, compared to BL, the GL conferred a reduced hazard of having a glaucoma procedure performed (hazard ratio [HR] = 0.72, 95% CI: 0.62-0.84, p < 0.001) and the combined outcome (HR = 0.90, 95% CI: 0.83-0.97, p = 0.006) but was not associated with having a second IOP medication (HR = 0.95, 95% CI: 0.87-1.03, p = 0.18). Compared to the bPGAs, however, GL conferred a reduced hazard in each comparison (second IOP medication HR = 0.87, 95% CI: 0.81-0.94, p < 0.001; surgery HR = 0.70, 95% CI: 0.61-0.81, p < 0.001; combined HR = 0.85, 95% CI: 0.79-0.92, p < 0.001). Sensitivity analyses confirmed these findings. CONCLUSIONS: GL was no less and possibly more effective in preventing the need for additional intervention than branded PGAs.

Pharmacologic Management for Heart Failure and Emerging Therapies.

PURPOSE OF REVIEW: This review aims to summarize the growing body of literature of HF with reduced ejection fraction (HFrEF) and preserved ejection fraction (HFpEF) with a focus on recent pharmacologics. RECENT FINDINGS: HFrEF continues to be more widely investigated than HFpEF. Ivabradine and combinatorial treatment with sacubitril and valsartan are promising newly approved therapies. Other experimental therapies have emerged, which include Serelaxin, Empagliflozin, Neuregulin, and Omecamtive mecarbil, among others. These drugs need to continue to be investigated for safety and efficacy. We predict ivabradine and combinatorial treatment with sacubitril-valsartan to develop as a widespread therapy. New therapies should be aimed at treating HFpEF or target the cardiomyocyte itself.

Electrocardiogram voltage discordance: Interpretation of low QRS voltage only in the precordial leads.

OBJECTIVES: To define clinical correlates of low voltage isolated to precordial leads on the surface electrocardiogram (ECG). INTRODUCTION: Low voltage (V) on the ECG is defined as QRS V<5mm in all limb leads and <10mm in all precordial leads. The diagnostic use of ECGs with low voltage isolated to the precordial leads with normal limb lead voltages is unclear. METHODS: Twelve-lead ECGs with QRS V>5mm in one or more limb leads and <10mm in all precordial leads were collected. Associated clinical conditions were determined from clinical data, echocardiograms, and chest radiographs. RESULTS: Low precordial voltage was found in 256 of 150,000 ECGs (~0.2%). 50.4% of patients had discordant ECGs that correlated with classic etiologies, with a higher incidence of LV dilation in those with classic etiologies than those without. CONCLUSION: Low precordial voltage is associated with classic etiologies and LV dilation.

Unusual drug reaction between valproate sodium and meropenem.

CASE: We describe here a rare case in which valproic acid (VPA) levels were affected by ertapenem but not by meropenem even though ertapenem and meropenem are in the same carbapenem class. A 68-year-old Filipino male treated with valproate for epilepsy and ertapenem for an infectious disease had decreased VPA levels during the first day of ertapenem therapy. His VPA level increased soon after terminating ertapenem therapy. Two types of carbapenems had different drug reactions with concomitant use of VPA in this patient. CONCLUSIONS: Closer monitoring of VPA concentrations are necessitated using carbapenems for treating infection in patients being administered VPA. Another option is the use of anti-epileptic drugs other than VPA if concomitant use with a carbapenem is warranted.

Protective effects of sodium para-amino salicylate on manganese-induced neuronal death: the involvement of reactive oxygen species.

OBJECTIVES: This study tested whether sodium para-amino salicylic dihydrate, an antibacterial drug for tuberculosis, could block manganese-induced apoptosis in SK-N-MC neurons. METHODS: Cell viability, Hoechst staining, dichlorofluorescin diacetate analysis for reactive oxygen species measurement, and immunoblotting were performed. KEY FINDINGS: In vitro, manganese chloride significantly decreased the viability of SK-N-MC cells, accompanied by apoptotic features such as changes in nuclear morphology. Sodium para-amino salicylic dihydrate inhibited these apoptotic characteristics through reducing intracellular reactive oxygen species generation, protecting mitochondrial membrane potential and caspase-3 activation. CONCLUSIONS: Sodium para-amino salicylic dihydrate inhibits manganese-induced apoptosis in neurons and may reduce manganese-mediated neurodegeneration.
