RESUMO
OBJECTIVE: To determine whether elements in ophthalmology residency applications are predictors of future resident performance. DESIGN: This multi-institutional, cross-sectional, observational study retrospectively reviewed the residency application materials of ophthalmology residents who graduated from residency from 2006 through 2018. Resident performance was scored by 2 faculty reviewers in 4 domains (clinical, surgical, academic, and global performance). Correlation between specific elements of the residency application and resident performance was assessed by Spearman correlation coefficients (univariate) and linear regression (multivariate) for continuous variables and logistic regression (multivariate) for categorical variables. SETTING: Seven ophthalmology residency programs in the US. PARTICIPANTS: Ophthalmology residents who graduated from their residency program. RESULTS: High-performing residents were a diverse group, in terms of sex, ethnicity, visa status, and educational background. Residents with United States Medical Licensing Examination Step 1 scores higher than the national average for that year had significantly higher scores in all 4 performance domains than those who scored at or below the mean (all domains P < 0.05). Residents who had honors in at least 4 core clerkships and who were members of Alpha Omega Alpha Medical Honor Society also had higher scores in all 4 performance domains (all domains P ≤ 0.04). Step 1 score (ρ=0.26, P < 0.001) and the difference between Step 1 score and the national average for that year (ρ=0.19, Pâ¯=â¯0.009) positively correlated with total resident performance scores. Residents who passed the American Board of Ophthalmology Written Qualifying Examination or Oral Examination on their first attempt had significantly higher Step 1/2 scores (P ≤ 0.005), Ophthalmology Knowledge Assessment Program scores (Pâ¯=â¯0.001), and resident performance scores (P ≤ 0.004). CONCLUSIONS: In this new landscape of increasing numbers of applicants to residency programs and changing of the Step 1 score to pass/fail, our findings may help guide selection committees as they holistically review applicants to select exceptional future residents in ophthalmology.

Purpose: To report two cases of benign essential blepharospasm (BEB) symptom relief in the setting of regular topical frankincense usage. Observations: The primary outcome measures for this report are (1) frequency of botulinum toxin (BT) injection appointments before and after the onset of regular frankincense usage and (2) patient report of symptoms. After starting frankincense, patient 1 decreased the frequency of her BT injection appointments from 5 to 8 months to 11+ months, eventually stopping BT injections altogether. Patient 2 decreased her BT appointments from every 3-4 months to approximately every 8 months after starting frankincense. Both patients had previously tried multiple additional treatments for their BEB symptoms which did not yield improvement; both patients reported significant improvement in their symptoms secondary to topical frankincense oil. Conclusion and Importance: Frankincense is a natural product of Boswellia trees. It has been used primarily for its anti-inflammatory properties for many years in multiple countries. We report two cases of individuals with long-standing, debilitating benign essential blepharospasm achieving significant symptom relief after beginning regular usage of topical frankincense essential oil. This natural oil offers an organic and effective treatment option for this chronic, progressive condition.
RESUMO
Construct: We investigated whether a situational judgment test (SJT) designed to measure professionalism in physicians predicts residents' performance on (a) Accreditation Council for Graduate Medical Education (ACGME) competencies and (b) a multisource professionalism assessment (MPA). Background: There is a consensus regarding the importance of assessing professionalism and interpersonal and communication skills in medical students, residents, and practicing physicians. Nonetheless, these noncognitive competencies are not well measured during medical education selection processes. One promising method for measuring these noncognitive competencies is the SJT. In a typical SJT, respondents are presented with written or video-based scenarios and asked to make choices from a set of alternative courses of action. Interpersonally oriented SJTs are commonly used for selection to medical schools in the United Kingdom and Belgium and for postgraduate selection of trainees to medical practice in Belgium, Singapore, Canada, and Australia. However, despite international evidence suggesting that SJTs are useful predictors of in-training performance, end-of-training performance, supervisory ratings of performance, and clinical skills licensing objective structured clinical examinations, the use of interpersonally oriented SJTs in residency settings in the United States has been infrequently investigated. The purpose of this study was to investigate whether residents' performance on an SJT designed to measure professionalism-related competencies-conscientiousness, integrity, accountability, aspiring to excellence, teamwork, stress tolerance, and patient-centered care-predicts both their current and future performance as residents on two important but conceptually distinct criteria: ACGME competencies and the MPA. Approach: We developed an SJT to measure seven dimensions of professionalism. During calendar year 2017, 21 residency programs from 2 institutions administered the SJT. We conducted analyses to determine the validity of SJT and USMLE scores in predicting milestone performance in ACGME core competency domains and the MPA in June 2017 and 3 months later in September 2017 for the MPA and 1 year later, in June 2018, for ACGME domains. Results: At both periods, the SJT score predicted overall ACGME milestone performance (r = .13 and .17, respectively; p < .05) and MPA performance (r = .19 and .21, respectively; p < .05). In addition, the SJT predicted ACGME patient care, systems-based practice, practice-based learning and improvement, interpersonal and communication skills, and professionalism competencies (r = .16, .15, .15, .17, and .16, respectively; p < .05) 1 year later. The SJT score contributed incremental validity over USMLE scores in predicting overall ACGME milestone performance (ΔR = .07) 1 year later and MPA performance (ΔR = .05) 3 months later. Conclusions: SJTs show promise as a method for assessing noncognitive attributes in residency program applicants. The SJT's incremental validity to the USMLE series in this study underscores the importance of moving beyond these standardized tests to a more holistic review of candidates that includes both cognitive and noncognitive measures.

The objective of this study was to observe the effect of medical cannabis in benign essential blepharospasm (BEB) as an adjunct to botulinum toxin. A retrospective chart review was performed on patients certified for medical cannabis use for BEB from September 2015 to May 2016. Patient demographics and responses, cannabis history, and severity indices were collected. Ten patients were certified for medical cannabis use. Five met the inclusion criteria, which was any patient with a diagnosis of BEB receiving standard botulinum toxin treatment who had started medical cannabis treatment by a registered distributor within the state, and was contactable by phone. Four patients discontinued use. Three out of four patients (75%) reported symptomatic improvement. Medical cannabis is an accepted therapy for muscle spastic disorders. Its potential as an adjunctive therapy for BEB remains unknown, and further investigations would be of benefit.
RESUMO
A 78-year-old woman presented with acute decreased vision in both eyes. She had been treated for a pituitary mass with a total of 4,500 centigray of external beam radiation 8 months prior to presentation. She was diagnosed with radiation optic neuropathy. Treatment with hyperbaric oxygen and intravenous steroids were initiated but vision remained poor.

Until recently, intricate details of the optical design of non-biomineralized arthropod eyes remained elusive in Cambrian Burgess-Shale-type deposits, despite exceptional preservation of soft-part anatomy in such Konservat-Lagerstätten. The structure and development of ommatidia in arthropod compound eyes support a single origin some time before the latest common ancestor of crown-group arthropods, but the appearance of compound eyes in the arthropod stem group has been poorly constrained in the absence of adequate fossils. Here we report 2-3-cm paired eyes from the early Cambrian (approximately 515 million years old) Emu Bay Shale of South Australia, assigned to the Cambrian apex predator Anomalocaris. Their preserved visual surfaces are composed of at least 16,000 hexagonally packed ommatidial lenses (in a single eye), rivalling the most acute compound eyes in modern arthropods. The specimens show two distinct taphonomic modes, preserved as iron oxide (after pyrite) and calcium phosphate, demonstrating that disparate styles of early diagenetic mineralization can replicate the same type of extracellular tissue (that is, cuticle) within a single Burgess-Shale-type deposit. These fossils also provide compelling evidence for the arthropod affinities of anomalocaridids, push the origin of compound eyes deeper down the arthropod stem lineage, and indicate that the compound eye evolved before such features as a hardened exoskeleton. The inferred acuity of the anomalocaridid eye is consistent with other evidence that these animals were highly mobile visual predators in the water column. The existence of large, macrophagous nektonic predators possessing sharp vision--such as Anomalocaris--within the early Cambrian ecosystem probably helped to accelerate the escalatory 'arms race' that began over half a billion years ago.

There are many neurological manifestations of vitamin B(12) deficiency. Optic neuropathy is a rare, but important, manifestation of vitamin B(12) deficiency that should be suspected in patients with risk factors for malnutrition. We present a case of a 68-year-old male who presented with bilateral decreased central vision for months and was found to have a low vitamin B(12) level. After a few months, his vision improved with parenteral vitamin B(12) supplementation. Vitamin B(12) optic neuropathy is a reversible, treatable cause of vision loss and may be a harbinger for other manifestations of the disease.
RESUMO
OBJECTIVES: To describe the clinical, perimetric, and electroretinographic (ERG) results of 4 patients with cone dysfunction following irofulven treatment including the histopathologic and immunocytochemical features of one patient's retinas. DESIGN: Observational case series. METHODS: The patients were examined clinically, including perimetric and ERG evaluations. Eyes from patient 1 and healthy postmortem eyes were processed for histopathologic and immunocytochemistry studies with antibodies specific for cones, rods, and reactive Müller cells. MAIN OUTCOME MEASURES: Clinical signs and symptoms, perimetry, ERG, retinal histopathologic and immunocytochemistry study results. RESULTS: All 4 patients had ERG changes consistent with abnormal cone responses and relatively normal rod responses. Compared with control eyes, the retina of patient 1 had approximately half the normal numbers of macular cones and fewer peripheral cones. The number of rods were normal but all rod and cone outer segments were shortened. CONCLUSION: High-dose irofulven treatment causes cone-specific damage with relative sparing of rods.

PURPOSE: Irofulven (6-hydroxymethylacylfulvene) is a novel agent, derived from illudin S, with potent apoptotic effects in preclinical models. In the Phase I trial evaluating intermittent weekly schedules, visual symptoms were dose limiting. The aim of this analysis was to better characterize the visual adverse events of irofulven and provide treatment guidelines. EXPERIMENTAL DESIGN: Clinical data from 277 patients entered in single-agent Phase I to II clinical trials who received irofulven on days 1 and 15 every 4 weeks; days 1, 8, and 15 every 4 weeks; or days 1 and 8 every 3 weeks were included in this multiparameter analysis. RESULTS: Overall, 74 patients (27%) experienced visual symptoms. The most frequently reported symptoms were flashing lights (12% of patients), blurred vision (9%), and photosensitivity (8%). Grade 3 toxicity was observed in 12 patients (4%). The incidence and severity of visual events were dose dependent, with no grade 3 visual events occurring at doses < or =0.50 mg/kg and grade 1 to 2 events in only 12% and 8% of patients, at doses of < or =0.50 mg/kg and < or =20 mg/m2, respectively. Grade 1 to 2 toxicity was reversible in most patients. Abnormal electroretinogram and abnormal visual fields were noted after irofulven treatment in 24 of 39 patients (62%) and 15 of 26 patients (58%), respectively. All but 1 patient who had electroretinogram assessment received doses >0.50 mg/kg. Clinical examination and visual field assessment were found to be better correlated with symptoms and appear to be more appropriate for surveillance of irofulven retinal symptoms than electroretinograms. CONCLUSIONS: On the basis of retained antitumor activity and reversibility of grade 1 and 2 visual symptoms at lower doses, it appears that an irofulven dose of < or =0.50 mg/kg or < or =20 mg/m2, not to exceed 50 mg in a single dose, given as a 30-minute infusion on days 1 and 8 every 3 weeks or days 1 and 15 every 4 weeks minimizes the frequency and severity of visual symptoms.
