RESUMO
BACKGROUND: Mycobacterium chimaera ocular infection is a rare disease that is linked to bypass devices used during cardiothoracic surgeries. Reported cases in the literature of ocular involvement preceding CNS involvement are based on clinical exam with no neuroimaging. Here we present a case of M. chimaera ocular infection with no CNS M. chimaera lesions on brain magnetic resonance imaging (MRI). CASE PRESENTATION: A 59-year-old female presented with altered mental status and blurred vision in February 2021. Her past medical history was significant for aortic valve replacement and ascending aortic aneurysm repair in 2017 complicated by known M. chimaera infection. She had been receiving azithromycin, ethambutol, rifampin, and amikacin as systemic anti-mycobacterium treatment. Her dilated fundus exam showed numerous yellow placoid circular lesions scattered throughout the macula and peripheral retina in both eyes with associated vitritis. Systemic workup, including brain MRI showed no acute infectious lesions. Her infections workup was unremarkable except for a positive toxoplasma IgM, for which she was treated with sulfamethoxazole/trimethoprim. One month later, a head computed tomography showed new numerous scattered round foci of hyperdensity throughout the cerebrum and brainstem thought to be foci of M. chimaera infection. Clofazimine was added per culture and sensitivity. MRI brain 1 month later showed mild decrease in conspicuity and number of these intensities while on anti-mycobacterium treatment. Her cognition had improved at that time as well. She was seen in retina clinic 2 months later where her exam showed similar retinal lesions with no associated vitritis or anterior chamber cell in bilateral eyes, suggesting a lack of active infection. Optical coherence tomography macula showed parafoveal cystoid macular edema bilaterally. She was started on steroidal and non-steroidal anti-inflammatory eye drops. CONCLUSIONS: To the best of our knowledge, this is the first case in the literature to report M. chimaera chorioretinitis with concomitant negative neuroimaging. Chorioretinal M. chimaera lesions should motivate high suspicion of CNS involvement prompting early neurological work up.

OBJECTIVE: Approximately half of all U.S. medical students are experiencing burnout. A previous study has demonstrated that higher levels of spirituality are associated with less burnout in medical students, yet no studies have examined the relationship between religious affiliation and burnout in medical students. The purpose of this study is to determine if specific religious affiliation and level of religious involvement is associated with less burnout in medical students. METHODS: A cross-sectional online survey was sent to all students attending five different osteopathic and allopathic medical schools in Kansas and Missouri. It contained a validated burnout measure, an item to identify religious affiliation, and items to quantify religious involvement. RESULTS: A response rate of 11.5% (495/4,300) was obtained. An ANOVA showed religious affiliations and burnout scores did not have any statistically significant relationships (F = 0.762, P = 0.619). Additionally, identification as an active participant within a religious affiliation had a statistically significant effect on burnout scores (F = 7.793, P = 0.005). CONCLUSIONS: This is the first study within the U.S. to show that religious affiliation is not associated with medical student burnout and that medical students who consider themselves to be active participants of their religion may be at lower risk of developing burnout, regardless of the faith they practice.

OBJECTIVES: To assess the prognostic significance of high vs. low grade coronary artery ectasia (CAE) and the impact of antithrombotic or anticoagulant therapy on adverse cardiac outcomes. BACKGROUND: There is paucity of knowledge on the impact of angiographic characteristics in CAE or that of antithrombotic or anticoagulant therapy on outcomes. METHODS AND RESULTS: In this retrospective study, we reviewed angiograms and medical records of all cases of confirmed CAE (2001-2011). Extent of CAE was categorized using the Markis classification. Types 1 and 2 were categorized as high-grade and types 3 and 4 as low-grade CAE. Angiographic flow was recorded as normal or sluggish (Assuntos

RESUMO
Purpose: The Coronavirus Disease 2019 (COVID-19) pandemic spurred vaccine development and resulted in the development of the novel mRNA COVID-19 vaccine and with it, a growing public concern of vaccine side effects. There are reports of ocular inflammatory processes such as episcleritis being possible side effects of COVID-19 vaccination. Here we reported the first case of unilateral episcleritis in a Crohn's disease patient following her third mRNA COVID-19 vaccination booster shot. Patient and Methods: A 27-year-old female presented with a 1-day history of right eye redness, itching, and burning. Patient reported developing these symptoms within 3-4 hours after vaccination. Her past medical history was relevant for Crohn's disease. Ophthalmic examination revealed right 2+ conjunctival injection that blanched with phenylephrine drops. Otherwise, her ophthalmic exam was unremarkable. The patient was started on artificial tears and ibuprofen 200 mg three times daily for one week. After one week all symptoms resolved, and ophthalmic examination was back to baseline. Conclusion: This is the first case in the literature of ophthalmic side effects in a Crohn's disease patient after the third mRNA COVID-19 booster. Patients with Crohn's disease may respond differently to booster vaccination. This case report may help healthcare providers when counselling Crohn's disease patients about future COVID-19 mRNA vaccine side effects.
RESUMO
Purpose The purpose of the study is to determine if instructional videos detailing the use of smartphone accessibility features may be used to improve quality of life and comfort with phone usage among patients with severe glaucoma. Design The design of the present study is an interventional case series. Methods The patients with vision loss due to severe glaucoma were recruited from one institution. Two surveys were completed to provide baseline data: one detailed their current use of smartphone accessibility features, and the other provided survey was the EuroQol 5 Dimension 5 Level (EQ-5D-5L) (EuroQol Group, Rotterdam, Netherlands), which is used to assess the quality of life. Then, the patients were shown a brief video with instructions on configuring the use of voice-over, magnification, and zoom functions, along with other features. To conclude, the patients completed the same surveys either at follow-up visits or by phone calls. Results Fifteen patients were recruited to participate in the study. At baseline, the participants used a median of one accessibility feature, with the most common feature being "text sizing/bolding." At follow-up, the participants averaged the gain of use of one accessibility feature and reported a decrease in text messaging visual limitation, although these findings did not reach statistical significance. Overall, the quality of life, as measured by the EQ-5D-5L, demonstrated a non-statistically significant increase of six points. Conclusions Despite the lack of statistical significance, our results indicate that providing instructional videos may benefit the patients' ability to navigate on their smartphones. Incorporating links or Quick Response (QR) codes to these instructional videos provides an opportunity to improve the quality of life at no additional risk to the patient. Further studies are needed with an increased population to investigate for any significance of our findings.
RESUMO
PURPOSE: To present a rare case of uveo-meningeal syndrome secondary to herpes simplex virus (HSV-1) in a patient with acute retinal necrosis. OBSERVATIONS: A 49-year-old female with a past medical history of herpes simplex encephalitis 18 years prior presented with a 3-day history of right sided headache and decreased vision of the right eye. Her visual acuity was 20/30 in the right eye and 20/20 in the left eye. Clinical examination revealed right relative afferent pupillary defect, panuveitis, and retinal necrosis. Examination of the left eye was unremarkable. Cerebral spinal fluid (CSF) analysis by polymerase chain reaction (PCR) was negative for herpes simplex virus 1 (HSV-1) but did reveal pleocytosis consistent with meningitis. The patient was admitted and empirically treated with intravenous acyclovir (10 mg/kg every 8 hours) and systemic steroids. Topical steroids and cycloplegia were also started. Magnetic resonance imaging revealed no leptomeningeal, pachymeningeal, or parenchymal enhancement. Systemic autoimmune and infectious workup were unremarkable. Based on clinical exam findings and negative PCR results, an anterior chamber tap was performed with aqueous fluid PCR testing which revealed 71,000 copies of HSV-1. A repeat lumbar puncture was performed on day three of admission and revealed a decrease in pleocytosis after initiation of acyclovir therapy and remained negative for HSV on PCR testing. She was discharged home on intravenous acyclovir, topical steroids, and topical cycloplegics. Her retinal necrotic lesions continued to regress and her headaches continued to improve. CONCLUSIONS AND IMPORTANCE: Uveo-meningeal syndromes are a rare clinical entity that involve the uvea, retina, and meninges. This case highlights the importance of aqueous fluid PCR testing despite negative CSF PCR, as it may hasten treatment with antiviral therapies to preserve vision and limit neurologic sequelae.
RESUMO
Acanthamoeba species are free-living protozoa found pervasively in water and soil, which can cause infections of the central nervous system, skin, and eye. Amoebic keratitis (AK) is a vision-threatening, often chronic infection that is associated with the use of soft contact lenses due to corneal microtrauma and improper cleaning and storage. Although AK infections are rare, they cause significant morbidity including vision loss due to the diagnostic and therapeutic challenges they pose. The clinical course is determined by the organism's inherent pathogenicity, delay of diagnosis, and the paucity of data on effective therapeutic regimens. The case series and review of literature that follows examine current latest best practices in AK diagnosis including in vivo confocal microscopy (IVCM) and therapeutic interventions including miltefosine.
RESUMO
PURPOSE: Multidrug resistance (MDR) represents a major obstacle to the success of antimicrobial fluoroquinolone (FQ) therapy. MDR-associated efflux protein pumps antimicrobial agents out of the corneal cells, leading to suboptimal eradication of microbes. This article examines whether long-term FQ (levofloxacin, ofloxacin, and gatifloxacin) therapy can modify the MDR phenotype (P-glycoprotein [P-gp]) on corneal epithelial cells (Statens Seruminstitut Rabbit Cornea [SIRC]). METHODS: To study the effect of FQ, SIRC cells without any exposure to FQ (control) were compared with the cells exposed to ofloxacin, levofloxacin, and gatifloxacin at a concentration of 10 µg/mL for 3 weeks. Efflux activity of P-gp was assessed by in vitro uptake studies (fluorescent and radioactive), flow cytometry, and quantitative real-time polymerase chain reaction (qRT-PCR). RESULTS: In the presence of FQ, elevated P-gp expression was noted with uptake, flow cytometry, and qRT-PCR analyses. This study confirms that long-term exposure to antibiotics, particularly FQ, can induce overexpression of P-gp efflux transporter present on the corneal cells. P-gp overexpression is commonly noticed in anticancer drug resistance cell lines; however, for the first time, this report describes overexpression of P-gp due to FQ exposure. CONCLUSIONS: Based on this result, it is suggested that strategies should be developed and implemented not only to overcome resistance to ocular pathogen but also to FQ-induced cellular resistance.
