Beyond the Label: Real-World Side Effects Experienced With FDA-Approved Drugs for Non-Melanoma Skin Cancers.

With immunotherapy historically focused on cutaneous melanoma, there has been a new wave of systemic medications available for treating non-melanoma skin cancers including basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and Merkel cell carcinoma (MCC). The immune checkpoint inhibitors approved by the FDA target programmed cell death protein 1 (PD-1) and the Hedgehog (Hh) signaling pathway. These medications have expanded treatment options; however, side effects are an important consideration. We used the FDA Adverse Events Reporting System (FAERS) to characterize the most prevalent, real-world side effects experienced by patients on these agents. Muscle spasms (23.45%), alopecia (16.06%), ageusia (12.02%), taste disorder (11.91%), and fatigue (11.67%) were the five most common side effects reported with medications used for BCC treatment. Logistic regression analysis showed males on vismodegib for BCC having greater odds of experiencing muscle spasms (aOR 1.33, P<0.001) and ageusia (aOR 1.34,  P<0.001) versus females, who were more likely to exhibit alopecia (aOR 1.82, P<0.001) and nausea (aOR 1.96, P<0.001). With SCC treatment, the 5 most reported adverse events were fatigue (5.58%), rash (3.59%), asthenia (3.59%), pruritus (3.19%), and pyrexia (2.79%). Patients taking cemiplimab-rwlc for BCC compared to SCC were more likely to experience disease progression (aOR 10.98, P=0.02). With medication labels providing an excessively daunting list of side effects, we characterize practical side effects seen in patients receiving systemic treatments for non-melanoma skin cancers.  J Drugs Dermatol. 2024;23(5):301-305. doi:10.36849/JDD.7968.

Real-World Experience With Teprotumumab in Patients With Dysthyroid Optic Neuropathy.

BACKGROUND: Teprotumumab, an insulin-like growth factor I receptor inhibitory antibody, improved proptosis, diplopia, inflammatory signs/symptoms, and quality of life in patients with active thyroid eye disease (TED) in clinical trials. The trials excluded patients with dysthyroid optic neuropathy (DON). Recently, many case reports and case series have reported the successful use of teprotumumab to treat DON. Here, we review the data from published cases and our clinical experience in treating patients having DON with teprotumumab. METHODS: A literature search was conducted of patients with DON treated with teprotumumab from January 2020 through September 2022. Data from DON patients from the authors' (M.A.T. and C.A.B.) clinical practice were included. Primary outcome measure was mean (SD) improvements for visual acuity, color vision, and visual fields. Improvements in proptosis and clinical activity score (CAS) and diplopia were compared before and after teprotumumab administration. RESULTS: Ten observational studies/case reports were identified along with 2 patients in our practice. In all, there were 24 active TED patients with DON (37 eyes) who were treated with teprotumumab. Mean (SD) age was 66.5 (13.6) years and 13 (54%) were females, disease duration ranged from 2 months to >15 years. 22/24 patients had none, minimal improvement or progression of visual loss with intravenous/oral corticosteroids, orbital decompression (n = 9), and orbital radiation (n = 2). There were 2 patients who received teprotumumab as the only therapy. Overall, 88% (21/24) reported improvement in visual acuity after teprotumumab and in 75% (18/24), improvement in vision was observed after just 2 infusions of teprotumumab. Three eyes had decompression surgery in close proximity to teprotumumab infusions and were excluded from analyses. Mean (SD) improvement in visual acuity was 3.73 lines (SD 3.74), range 2-15 lines in 33 eyes. The mean (SD) improvement in the mean deviation on visual field testing in 15 eyes was 5.6 db (3.0 db). Mean (SD) improvement in proptosis was 4.37 mm (SD: 2.11) (20 patients, 32 eyes); and clinical activity score: mean reduction of 5.1 (1.3) for 18 patients. Teprotumumab was well tolerated in all but one patient. Adverse events reported included fatigue, dysgeusia, hearing loss, nausea, hyperglycemia, and muscle spasms. CONCLUSIONS: Teprotumumab is an effective treatment for DON in our experience and in published cases in whom treatment with steroids, surgery, or orbital radiation was unsuccessful.

Surgical Management of Overgrowth Syndrome With Bilateral Vision-Threatening Ptosis.

We describe the first case reported in ophthalmological literature of the surgical management of a 17-month-old boy with bilateral vision-threatening ptosis, tarsomegaly, ectropion, and euryblepharon secondary to suspected overgrowth syndrome. We elaborate on the major challenges associated with surgical management including the natural and asymmetric growth of oversized tissue, the high likelihood of scarring and formation of disorganized tissue, and risks of frequent intubation in these patients who may have lesions that compromise critical structures such as the airway. Ultimately, surgical intervention is encouraged primarily if vision or ocular health is threatened and secondarily to achieve good cosmesis.

The distribution of industry payments among pediatric dermatologists from 2015 to 2021.

BACKGROUND/OBJECTIVES: To understand the landscape of industry payments to pediatric dermatologists to foster transparency and identify potential disparities in funding. METHODS: Using the Centers for Medicare and Medicaid Services (CMS) Open Payments database, a national cross-sectional study was performed examining payments to pediatric dermatologists from 2015 to 2021. RESULTS: Of the 147 pediatric dermatologists who received industry funding, 35 were male and 112 were female. $9 million in payments was amassed, with 10% of pediatric dermatologists accounting for 94% of total industry payments. Consulting was the most common service, with Pfizer Inc., Amgen Inc., and Regeneron Healthcare Solutions Inc. representing the top three companies. Mean payment was $143,836 for males and $35,943 for females (p < .001). Eight female and seven male pediatric dermatologists received payments in the top 10th percentile, with different average payment in this subgroup (females $447,588 vs. males $698,746, p = .03). 11 states did not have a pediatric dermatologist receiving industry payments, while California (19) and Texas (12) had the most. CONCLUSIONS: There are approximately 400 board-certified pediatric dermatologists in the United States and fewer than 40% are receiving monetary compensation from private industry. A fraction of physicians accounted for a majority of total industry payments and industry payments to male pediatric dermatologists were higher despite nearly triple the number of female pediatric dermatologists. With the rise of valuable partnerships between healthcare and industry in modern medicine, the implications of geographic, gender, and financial disparity of industry payments in pediatric dermatology are worthy of further study.

More than just a stye: identifying seasonal patterns using google trends, and a review of infodemiological literature in ophthalmology.

PURPOSE: We aim to evaluate the utility of internet search query data in ophthalmology by: (1) Evaluating trends in searches for styes in the United States and worldwide, and (2) Performing a review of literature of infodemiological data in ophthalmology. METHODS: Google Trends search data for "stye" was analyzed from January 2004 to January 2020 in the United States and worldwide. Spearman's correlation coefficient and sinusoidal modeling were performed to assess the significance and seasonality of trends. Review of literature included searches for "ophthalmology Google trends," "ophthalmology twitter trends," "ophthalmology infodemiology," "eye google trends," and "social media ophthalmology." RESULTS: Searches for styes were cyclical in the United States and globally with a steady increase from 2004 to 2020 (sum-of-squares F-test for sinusoidal model: p < .0001, r2 = 0.96). Peak search volume index (SVI) months were 7.9 months in the United States and 6.8 months worldwide. U.S. temperature and SVI for stye were correlated in the United States at the state, divisional, and country-wide levels (p < .005; p < .005; p < .01 respectively). Seven articles met our literature review inclusion criteria. CONCLUSIONS: We present a novel finding of seasonality with global and U.S. searches for stye, and association of searches with temperature in the United States. Within ophthalmology, infodemiological literature has been used to track trends and identify seasonal disease patterns, perform disease surveillance, improve resource optimization by identifying regional hotspots, tailor marketing, and monitor institutional reputation. Future research into this domain may help identify further trends, improve prevention efforts, and reduce medical costs.

Risk factors for enucleation or evisceration in endophthalmitis.

PURPOSE: To identify clinical risk factors for enucleation or evisceration in patients with endophthalmitis at an academic institution. METHODS: A retrospective review of patients diagnosed with endophthalmitis at Wilmer Eye Institute from 2010 to 2019 was conducted. Clinical characteristics, including demographics, cause for endophthalmitis, microbial culture results, salvaging procedures and surgical intervention were recorded. In patients who underwent enucleation or evisceration, type of surgery and placement of a primary implant were recorded. Chi-squared, Student's t-tests and multivariate analysis were used to identify clinical factors that predicted enucleation or evisceration. RESULTS: Two hundred and fifty three patients treated for endophthalmitis over the study period were identified, of which 25 (9.88%) underwent enucleation or evisceration. Risk factors for enucleation or evisceration included poor presenting visual acuity (OR 7.86, CI: 2.26, 27.3), high presenting intraocular pressure (OR 1.07, CI: 1.03, 1.12), presence of relative afferent pupillary defect (OR 3.69, CI: 1.20, 11.37) and positive vitreous culture for methicillin-resistant staphylococcus aureus (MRSA) (OR 18.3, CI: 1.54, 219.2) on multivariate analysis. Patients undergoing enucleation or evisceration were also more likely to have trauma, corneal ulcer or combined causes for endophthalmitis and underwent fewer salvaging surgical and procedural interventions. There were no significant differences in characteristics of those receiving enucleation versus evisceration in our cohort. CONCLUSION: Patients with endophthalmitis who underwent enucleation or evisceration had more severe disease on presentation compared to those treated with eye sparing therapy. Presenting clinical characteristics may have a role in triage and management decisions for patients presenting with severe endophthalmitis.

Peripheral-to-central ratio of Guttae: validity and reliability of an objective method to characterize severity of Fuchs endothelial corneal dystrophy.

PURPOSE: Common methods of measuring severity of Fuchs endothelial corneal dystrophy (FECD) are limited in objectivity, reliability, or start with a variable baseline that prevents distinguishing healthy from affected eyes. The aim of this study was to describe a method of grading FECD that overcomes these limitations. METHODS: Fifteen patients with Fuchs endothelial corneal dystrophy were included in the study. Guttae were imaged with a slit lamp beam 8 mm tall; the bottom 4 mm half of each image was divided into two equally-sized sections. Guttae were counted by four independent graders blinded to disease severity scores. The peripheral:central guttae ratio was compared to modified Krachmer clinical severity scores. The peripheral:central guttae ratio was compared between mild (severity 0.5-3) versus moderate-to-severe (severity 4-5) disease. Receiver operating characteristics defined optimal ratio cutoffs for mild versus moderate-to-severe disease. RESULTS: Increased peripheral guttae and peripheral:central guttae ratio correlated with Krachmer severity (p = 0.021 and p = 0.009, respectively). The difference between mild and moderate-to-severe cases for the peripheral:central guttae ratio was significant (p < 0.001). Inter-rater reliability of total guttae count was high (coefficient = 0.82, p < 0.001). A peripheral:central guttae ratio of 0.16 was the ideal cut-off point (area under the curve = 0.79, sensitivity = 0.78, and specificity = 0.80). CONCLUSION: In this pilot study, the peripheral:central ratio of guttae correlates with subjective clinical severity of Fuchs dystrophy. It starts at a common baseline, has good inter-rater reliability, does not require dilation, and can be conducted with a smartphone and slit-lamp.

Testing a Popular Smartphone Application for Colour Vision Assessment in Healthy Volunteer Subjects.

We aimed to compare the Ishihara pseudoisochromatic colour vision test with a colour vision test from a popular smartphone application (EyeHandBook [EHB]) using digital image processing to simulate colour vision deficiencies. Three digital versions of the Ishihara and EHB slides were created: full colour; 32 bit- greyscale (removing all colour information); and blue channel (to simulate red-green colour vision deficiencies). Twenty healthy volunteers were shown each colour-edited plate. The answers they reported were compared with what would be expected for that colour-simulation scenario based on the answer key provided in the Ishihara booklet ("expected" answer). There were nine plates that had comparable patterns between the EHB and Ishihara test. We found no significant difference in the overall proportion of "expected" answers for the full colour (p = .35), 32 bit-greyscale (p = .39) and blue channel (p = .22) conditions. There were significant differences between the proportion of "expected" answers among six individual colour- edited plates (p < .05 for each). Colour vision assessment from the EHB is distinct from comparable Ishihara plates. Clinical scenarios that require serial assessment of colour vision may benefit from using the same modality consistently rather than exchanging between the two tests with the assumption of equivalence. Refinement of digital colour editing techniques beyond 32-bit greyscale and RGB channel splitting is necessary in order to accurately simulate colour vision deficiency.

Seasonal variability in public searches of keratosis pilaris: How the internet can illuminate a pattern in public interest.

In this study, we examine keratosis pilaris search patterns using Google Trends to determine any seasonality. Monthly searches were collected from January 2004 to January 2020 using "keratosis pilaris" as the search term in the Google Trends database. The US search data were compared to monthly temperatures and tested for correlation. Worldwide search interest was also acquired and, along with the US data, a two-model analysis was performed to determine any seasonal patterns. Peaks in search interest closely overlapped with higher temperatures in the United States and showed correlation (.44; P < .0001). The US and worldwide search interest also exhibited seasonality, which was confirmed with a sinusoidal regression being the best-fit model (R2 = .867 and .895). These results show higher search volume during warmer months in the United States and a clear cyclical pattern in searches worldwide and in the United States. Examination of these trends could elucidate peaks that health care providers may not have been aware of yielding improved resource allocation and preparedness for larger volume periods. This information in conjunction with clinical data could also shed more light in the future on potential peak seasons of incidence and prevalence.

History of traumatic brain injury interferes with accurate diagnosis of Alzheimer's dementia: a nation-wide case-control study.

Traumatic brain injury (TBI) and Alzheimer's disease (AD) bear a complex relationship, potentially increasing risk of one another reciprocally. However, recent evidence suggests post-TBI dementia exists as a distinct neurodegenerative syndrome, confounding AD diagnostic accuracy in clinical settings. This investigation sought to evaluate TBI's impact on the accuracy of clinician-diagnosed AD using gold standard neuropathological criteria. In this preliminary analysis, data were acquired from the National Alzheimer's Coordinating Centre (NACC), which aggregates clinical and neuropathologic information from Alzheimer's disease centres across the United States. Modified National Institute on Aging-Reagan criteria were applied to confirm AD by neuropathology. Among participants with clinician-diagnosed AD, TBI history was associated with misdiagnosis (false positives) (OR = 1.351 [95% CI: 1.091-1.674], p = 0.006). Among participants without clinician-diagnosed AD, TBI history was not associated with false negatives. TBI moderates AD diagnostic accuracy. Possible AD misdiagnosis can mislead patients, influence treatment decisions, and confound research study designs. Further work examining the influence of TBI on dementia diagnosis is warranted.

What Do Plastic Surgery Patients Think of Financial Conflicts of Interest and the Sunshine Act?

BACKGROUND: The purpose of this study was to evaluate patients' views of conflicts of interest (COI) and their comprehension of recent legislation known as the Physician Payments Sunshine Act. This report constitutes the first evaluation of plastic surgery patients' views on COI and the government-mandated Sunshine Act. METHODS: This cross-sectional study invited patients at an academic, general plastic surgery outpatient clinic to complete an anonymous survey. The survey contained 25 questions that assessed respondents' perceptions of physician COI and awareness of the Sunshine Act. Analyses were performed to examine whether perspectives on COI and the Sunshine Act varied by level of education or age. RESULTS: A total of 361 individuals completed the survey (90% response rate). More than half of respondents with an opinion believed that COI would affect their physician's clinical decision-making (n = 152, 52.9%). Although almost three fourths (n = 196, 71.2%) believed that COI should be regulated and COI information reported to a government agency, the majority were not aware of the Sunshine Act before this survey (n = 277, 81.2%) and had never accessed the database (n = 327, 95.9%). More than half of patients (n = 161, 59.2%) stated that they would access a publicly available database with physicians' COI information. A larger proportion of older and educated patients believed that regulation of physicians' COI was important (P < 0.001). CONCLUSIONS: Awareness of and access to plastic surgeon COI information is low among plastic surgery patients. Older and more educated patients believed that transparency regarding COI is important with regard to their clinical care.

A cross-sectional analysis of medications used by patients reporting alopecia areata on the FDA adverse events reporting system.

BACKGROUND: Alopecia areata (AA) is an autoimmune condition that leads to patchy, nonscarring hair loss. Its etiology remains unknown; the condition can be debilitating for patients, impacting their psychosocial wellbeing. Various triggers have been reported, ranging from genetic predisposition and infections to environmental factors. Medications have also been thought to be an inciting factor in AA. METHODS: Using the Food and Drug Administration (FDA) Adverse Events Reporting System (FAERS), all cases reporting AA as an adverse event were used to capture associated medications and patient characteristics. RESULTS: There were 1,331 AA cases reported as an adverse event with medication use. Monoclonal antibodies accounted for 6 out of the top 10 drugs associated with the highest number of AA cases. Males were more likely to report AA when taking adalimumab (OR: 1.79, P = 0.04) and dupilumab (OR: 2.56, P = 0.03) compared to females. Individuals between 42 and 64 years old accounted for 46.7% of AA cases. Lastly, females in older age groups showed greater odds of developing AA compared to males (OR: 1.03, P < 0.01). CONCLUSIONS: Based on the FAERS, there has been a steady rise in AA cases, and monoclonal antibodies were the most frequently cited medication class tied to AA. With a dearth of literature on triggers and patient demographics, we sought to describe features of AA cases that could increase awareness and be used to improve future clinical outcomes in patients.

The association of stroke with herpes zoster ophthalmicus.

BACKGROUND/OBJECTIVES: Studies have reported an association between herpes zoster ophthalmicus (HZO) and stroke. We sought to validate this association with rigorous controls for both medical comorbidities and social factors using a nationwide U.S. administrative medical claims database. SUBJECTS/METHODS: A two-step approach was taken: first a retrospective case-control study was performed, followed by a self-controlled case series (SCCS). For the case control study, cox proportional hazard regression with inverse proportional treatment weighting assessed the hazard for stroke. In the SCCS, incidence of stroke was compared prior to and after the diagnosis of HZO. RESULTS: For the case-control study, 25,720 cases and 75,924 controls met our eligibility criteria. 1712 (6.7%) and 4544 (6.0%) strokes occurred in the case and control groups respectively, conferring an 18% increased risk of stroke in the observed 1-year post-HZO period (HR = 1.18, 95% CI: 1.12-1.25, p < 0.001). SCCS analysis showed the risk for stroke was highest in the month immediately after HZO episode compared to any other time range (1-30 days after, relative risk 1.58, p < 0.001) and even higher when assessing time more distal time points prior to the HZO diagnosis (days 1-30 after HZO diagnosis had RR = 1.69 (95% CI: 1.38-2.07) and RR = 1.93 (95% CI: 1.55-2.39) compared with days -120 to -91 and -150 to -121 prior to index, respectively (p < 0.001). CONCLUSIONS: After accounting for stroke risk factors, our analysis confirms the association between HZO and stroke, with highest risk in the immediate month after an episode.

The top 100 most cited Mohs micrographic surgery articles: an analysis of Altmetrics data from 2010 to 2020.

With skin cancer rates rising, there is a consistent stream of literature published on Mohs micrographic surgery (MMS). However, there are no studies examining MMS article visibility and readership patterns. The Altmetric Attention Score (AAS) is a metric that quantifies article distribution on media platforms. We analyzed the 100 most cited MMS publications from 2010 to 2020 and constructed multivariate regression models using top 25th percentile AASs and mentions on Facebook, Twitter, and new outlets as outcome variables. Articles with an AAS in the top 25th quartile consistently performed better with higher citations, Twitter mentions, Facebook mentions, and journal impact factors compared to articles in the lower three quartiles (53.8 vs 33.9; 4.68 vs 0.44; 0.32 vs 0.08; 53.5 vs 14.6; p < 0.05 for all). There were significantly lower female last authors versus males in the top quartile of AAS articles, with males 142 times more likely to have articles in the top quartile (p < 0.05). Studies comparing MMS to other surgical techniques and funded articles had higher odds of being in the top quartile of AASs (aOR 29.63 p < 0.05; aOR 74.50 p < 0.05). AASs can be useful to understand public interest, readership, and article features that influence the reach of MMS literature.

Interface fluid syndrome after LASIK surgery: retrospective pooled analysis and systematic review.

Interface fluid syndrome (IFS) is a complication associated with laser in situ keratomileusis (LASIK) surgery where a fluid pocket in the corneal stroma decreases visual acuity. A systematic review of IFS cases using PRISMA guidelines was performed yielding a total of 33 patients. 2 outcomes were selected for logistic regression analysis: final corrected distance visual acuity (CDVA) and need for surgical management. Results showed 33.3% of patients required surgery, 51.5% had their IFS resolve within 1 month or sooner, and 51.5% had final CDVA 20/25 or better. Higher presenting intraocular pressure (IOP) and duration of IFS ≤1 month was associated with higher odds of final CDVA 20/25 or better (adjusted odds ratio [aOR] 1.12, P = .04; aOR 7.71, P = .02, respectively). Endothelial cell dysfunction led to 17.55 greater odds for requiring surgical compared to medical management (aOR 0.36, P = .04). Presenting IOP and duration of IFS predicted final CDVA, while prior endothelial cell dysfunction predicted need for surgery.

Missed games, financial losses, and characteristics of eye injuries in the National Basketball Association during the 2010-2011 to 2017-2018 seasons.

PURPOSE: The purpose is to report financial loss, demographic metrics, and mechanisms of injury associated with eye injuries in the National Basketball Association (NBA) from the 2010-2011 to 2017-2018 seasons. METHODS: We performed a retrospective review of eye injuries in the NBA from the 2010-2011 to 2017-2018 seasons using publicly available information from Basketball Reference and the Pro Sports Transactions websites. Only injuries of the eye and adnexa that caused players to miss games in the regular season and playoffs were included in the study. Financial loss was calculated based on the regular season salary of the players and normalized for inflation with 2018 as the base year. RESULTS: There were 30 eye injuries causing a total of 106 missed games and $7,486,770 in financial losses across eight seasons. Linear regressions showed a moderately positive increase in eye injuries (Pearson's r = 0.68, P = 0.07, and 0.79 injuries per year/1000 game-days increase) and financial losses (Pearson's r = 0.67, P = 0.07, and $185.75 increase per year/1000 game-days) over time. There were significantly more games missed due to orbital fractures than games missed due to contusions/lacerations (11.5 vs. 2.8 missed games, P = 0.01). CONCLUSION: We demonstrate an increasing trend of eye injuries in the NBA, resulting in increased financial loss. Injuries may be varied in type and affect the number of games missed.

Association of Proton Pump Inhibitor/Histamine-2 Blocker Use and Ocular Toxoplasmosis: Findings from a Large US National Database.

OBJECTIVE: To test the hypothesis that the use of proton pump inhibitors (PPIs) is associated with an increased risk of being diagnosed with toxoplasmic retinochoroiditis. DESIGN: Retrospective, matched case-control study using data from 2000 to 2020. PARTICIPANTS: Patients with ocular toxoplasmosis and controls were matched 5:1 for age, sex, and race, with the eligibility date ± 3 months from the index date of exposed match. Patients aged < 18 years with congenital toxoplasmosis, having < 2 years in the insurance plan before the index date, and without ≥ 1 visit to an eyecare provider before the index date were excluded from the study. METHODS: Patients with ocular toxoplasmosis were identified using the International Classification of Diseases, Ninth Revision and International Classification of Diseases, Tenth Revision codes, and PPI use or diseases highly associated with PPIs were identified using national drug codes from an administrative medical claims database. MAIN OUTCOME MEASURES: The primary outcome was defined as having a prescription for a PPI or histamine-2 (H2) blocker. Multivariable logistic regression analyses were performed, controlling for demographic and systemic health variables. RESULTS: A total of 4069 cases and 19 177 controls met the eligibility criteria. Of the 4069 patients with ocular toxoplasmosis, 989 (24.3%) were on PPI/H2 blockers compared with 3763 of 19 177 (19.2%) controls. The adjusted logistic regression model demonstrated 1.28 greater odds of PPI/H2 blocker use in cases of ocular toxoplasmosis than matched controls (95% confidence interval, 1.17-1.40; P < 0.001). CONCLUSIONS: Proton pump inhibitor/H2 blocker exposure was associated with an increased risk of being diagnosed with ocular toxoplasmosis, corroborating findings from a prior case series. FINANCIAL DISCLOSURE(S): Proprietary or commercial disclosure may be found after the references.

Utility of diffusion-weighted imaging to differentiate benign and malignant solid orbital tumours.

OBJECTIVE: We assessed the utility of apparent diffusion coefficients (ADCs) derived from diffusion-weighted imaging to differentiate benign and malignant orbital tumours by oculoplastic surgeons in the clinical setting and sought to validate observed ADC cut-off values. DESIGN AND PARTICIPANTS: Retrospective review of patients with benign or malignant biopsy-confirmed orbital tumours. METHODS: Blinded graders including 2 oculoplastic surgeons, 1 neuroradiologist, and 1 medical student located and measured orbital tumour ADCs (10-6 mm2/s) using the Region of Interest tool. OUTCOME MEASURES: Nonradiologist measurements were compared with each other to assess reliability and with an expert neuroradiologist measurement and final pathology to assess accuracy. RESULTS: Twenty-nine orbital tumours met inclusion criteria, consisting of 6 benign tumours and 23 malignant tumours. Mean ADC values for benign orbital tumours were 1430.59 ± 254.81 and 798.68 ± 309.12 mm2/s for malignant tumours. Our calculated optimized ADC cut-off to differentiate benign from malignant orbital tumours was 1120.84 × 10-6 mm2/s (sensitivity 1, specificity 0.9). Inter-rater reliability was excellent (intraclass correlation coefficient = 0.92; 95% CI, 0.86-0.96). Our 3 graders had a combined accuracy of 84.5% (92.3%, 92.3%, and 65.4%). CONCLUSIONS: Our ADC cut-off of 1120.84 × 10-6 mm2/s for benign and malignant orbital tumours agrees with previously established values in literature. Without priming with instructions, training, or access to patient characteristics, most tumours were correctly classified using rapid ADC measurements. Surgeons without radiologic expertise can use the ADC tool to quickly risk stratify orbital tumours during clinic visits to guide patient expectations and further work-up.

Artificial Intelligence Automation of Proptosis Measurement: An Indicator for Pediatric Orbital Abscess Surgery.

INTRODUCTION: To evaluate the ability of artificial intelligence (AI) software to quantify proptosis for identifying patients who need surgical drainage. METHODS: We pursued a retrospective study including 56 subjects with a clinical diagnosis of subperiosteal orbital abscess (SPOA) secondary to sinusitis at a tertiary pediatric hospital from 2002 to 2016. AI computer software was developed to perform 3D visualization and quantitative assessment of proptosis from computed tomography (CT) images acquired at the time of hospital admission. The AI software automatically computed linear and volume metrics of proptosis to provide more practice-consistent and informative measures. Two experienced physicians independently measured proptosis using the interzygomatic line method on axial CT images. The AI software and physician proptosis assessments were evaluated for association with eventual treatment procedures as standalone markers and in combination with the standard predictors. RESULTS: To treat the SPOA, 31 of 56 (55%) children underwent surgical intervention, including 18 early surgeries (performed within 24 h of admission), and 25 (45%) were managed medically. The physician measurements of proptosis were strongly correlated (Spearman r = 0.89, 95% CI 0.82-0.93) with 95% limits of agreement of ± 1.8 mm. The AI linear measurement was on average 1.2 mm larger (p = 0.007) and only moderately correlated with the average physicians' measurements (r = 0.53, 95% CI 0.31-0.69). Increased proptosis of both AI volumetric and linear measurements were moderately predictive of surgery (AUCs of 0.79, 95% CI 0.68-0.91, and 0.78, 95% CI 0.65-0.90, respectively) with the average physician measurement being poorly to fairly predictive (AUC of 0.70, 95% CI 0.56-0.84). The AI proptosis measures were also significantly greater in the early as compared to the late surgery groups (p = 0.02, and p = 0.04, respectively). The surgical and medical groups showed a substantial difference in the abscess volume (p < 0.001). CONCLUSION: AI proptosis measures significantly differed from physician assessments and showed a good overall ability to predict the eventual treatment. The volumetric AI proptosis measurement significantly improved the ability to predict the likelihood of surgery compared to abscess volume alone. Further studies are needed to better characterize and incorporate the AI proptosis measurements for assisting in clinical decision-making.

Predictive Factors of Research Productivity among Ophthalmology Residents: A Benchmark Analysis.

Introduction Positive and negative associations between prior publications and future research productivity is described in other fields, but no such analysis exists for ophthalmology. We conducted a study to determine characteristics of residents exhibiting research productivity during residency. Methods Using San Francisco Match and Program Web sites, a roster of ophthalmology residents in 2019 to 2020 was compiled, and publication data was collected via PubMed and Google Scholar on a random sample of 100 third-year residents. Results The median number of publications generated by ophthalmology residents before residency is 2 (range 0-13). Thirty-seven, 23, and 40 residents had zero, one, and two or more papers published during residency, respectively, with a median of 1 (range 0-14). On univariate analysis, compared with residents who published zero or one paper, those who published ≥ 2 were more likely to have more preresidency publications (odds ratio [OR] 1.30; p = 0.005), attend a top-25 ranked residency program by multiple metrics including Doximity reputation (OR 4.92; p < 0.001), and have attended a top-25 ranked medical school program by U.S. News and World Report (OR 3.24; p = 0.03). However, on adjusted analyses, the only factor that remained significant for predicting publications in residency was whether the residency program attended was top 25 ranked (OR 3.54; p = 0.009). Discussion/Conclusion With the advent of the United States Medical Licensing Examination Step 1 pass/fail system, greater emphasis will be placed on other metrics, including research. This is the first benchmark analysis examining factors predictive of publication productivity in ophthalmology residents. Our study suggests that the residency program attended, not the medical school attended or prior publication history, plays an influential role in the number of publications produced during residency, highlighting the importance of factors to support research on the institutional level, such as mentorship and funding, rather than historical factors in research productivity by the resident.
