Anterior Nasal Superior Oblique Tendon Syndrome: A Case Series: Short title: Anterior Nasal Superior Oblique Tendon Syndrome.

PURPOSE: To evaluate the clinical characteristics and management of patients with an anteriorly and nasally inserted superior oblique tendon. DESIGN: Retrospective interventional case series. METHODS: Institutional clinical records between 2020 and 2024 were retrospectively reviewed for 9 consecutive patients in whom the superior oblique (SO) tendon was inserted anterior to the equator and nasal to the superior rectus muscle. Information collected included age, sex, ocular and surgical history, preoperative and postoperative data (ophthalmologic examinations, strabismus measurements, ductions and versions), intraoperative findings, need for additional surgery, and follow-up time. RESULTS: All nine patients were found to have an anomalous insertion of the SO tendon. Three were of congenital origin and six were acquired following ocular surgery. Among the acquired cases, all but one resulted from incarceration of the tendon from post-surgical scar tissue formation. The remaining acquired case was due to a prior deliberate anterior and nasal transposition of the superior oblique. This case series demonstrated varying degrees of vertical deviations, lateral incomitance, and limited depression. Repositioning the SO to its normal insertion site yielded equivocal improvement in ocular alignment. CONCLUSION: Anterior nasal superior oblique tendon syndrome is a rare clinical entity characterized by an anti-depressor effect. Vertical deviations, hypertropia worse in downgaze, limited depression worse in adduction for congenital cases and in abduction for acquired cases, and lateral incomitance may be indicative of this anomaly. In acquired cases following surgery, additional findings may include limited depression worse in abduction, esotropia in abduction, V-pattern esotropia, and enophthalmos in downgaze. Surgical repositioning of the SO along its normal anatomical trajectory is recommended for treatment. However, outcomes may be variable and achieving a complete resolution of this syndrome can be challenging.

Enhanced RHO-ROCK signaling is associated with CRELD2 production and fibroblast recruitment in cutaneous squamous cell carcinoma.

A key characteristic of cancer cells is their ability to induce changes in their microenvironment that render it permissive to tumor growth, invasion and metastasis. Indeed, these changes are required for tumor progression. Consequently, the tumor microenvironment is emerging as a key source of new targets against cancer, with novel therapies aimed at reversing tumor-promoting changes, reinstating a tumor-hostile microenvironment and suppressing disease progression. RHO-ROCK signaling, and consequent tension within the cellular actomyosin cytoskeleton, regulates a paracrine signaling cascade that establishes a tumor-promoting microenvironment. Here, we show that consistent with our observations in breast cancer, enhanced ROCK activity and consequent production of CRELD2 is associated with the recruitment and tumor-promoting polarization of cancer-associated fibroblasts in cutaneous squamous cell carcinoma. Our observations provide support for the notion that the role of RHO-ROCK signaling in establishing a tumor-promoting microenvironment may be conserved across patients and potentially also different cancer types.

Creation of an asynchronous faculty development curriculum on well-written narrative assessments that avoid bias.

BACKGROUND: The COVID-19 pandemic in parallel with concerns about bias in grading resulted in many medical schools adopting pass/fail clinical grading and relying solely on narrative assessments. However, narratives often contain bias and lack specificity. The purpose of this project was to develop asynchronous faculty development to rapidly educate/re-educate > 2000 clinical faculty spread across geographic sites and clinical disciplines on components of a well-written narrative and methods to minimize bias in the assessment of students. METHODS: We describe creation, implementation, and pilot data outcomes for an asynchronous faculty development curriculum created by a committee of volunteer learners and faculty. After reviewing the literature on the presence and impact of bias in clinical rotations and ways to mitigate bias in written narrative assessments, the committee developed a web-based curriculum using multimedia learning theory and principles of adult learning. Just-in-time supplemental materials accompanied the curriculum. The Dean added completion of the module by 90% of clinical faculty to the department chairperson's annual education metric. Module completion was tracked in a learning management system, including time spent in the module and the answer to a single text entry question about intended changes in behavior. Thematic analysis of the text entry question with grounded theory and inductive processing was used to define themes of how faculty anticipate future teaching and assessment as a result of this curricula. OUTCOMES: Between January 1, 2021, and December 1, 2021, 2166 individuals completed the online module; 1820 spent between 5 and 90 min on the module, with a median time of 17 min and an average time of 20.2 min. 15/16 clinical departments achieved completion by 90% or more faculty. Major themes included: changing the wording of future narratives, changing content in future narratives, and focusing on efforts to change how faculty teach and lead teams, including efforts to minimize bias. CONCLUSIONS: We developed a faculty development curriculum on mitigating bias in written narratives with high rates of faculty participation. Inclusion of this module as part of the chair's education performance metric likely impacted participation. Nevertheless, time spent in the module suggests that faculty engaged with the material. Other institutions could easily adapt this curriculum with provided materials.

Creating a win-win for the health system and health Profession's education: a direct observation clinical experience with feedback iN real-time (DOCENT) for low acuity patients in the emergency department.

BACKGROUND: Clinical education across the professions is challenged by a lack of recognition for faculty and pressure for patient throughput and revenue generation. These pressures may reduce direct observation of patient care provided by students, a requirement for both billing student-involved services and assessing competence. These same pressures may also limit opportunities for interprofessional education and collaboration. METHODS: An interprofessional group of faculty collaborated in a sequential quality improvement project to identify the best patients and physical location for a student teaching clinic. Patient chief complaint, use of resources, length of stay, estimated severity of illness and student participation and evaluation of the clinic was tracked. RESULTS: Clinic Optimization and Patient Care: Five hundred and thirty-two emergency department (ED) patients were seen in the first 19 months of the clinic. A clinic located near the ED allowed for patients with higher emergency severity index and greater utilization of imaging. Patients had similar or lower lengths of stay and higher satisfaction than patients who remained in the ED (p < 0.0001). In the second clinic location, from October 2016-June 2019, 644 patients were seen with a total of 667 concerns; the most common concern was musculoskeletal (50.1%). Student Interprofessional Experience: A total of 991 students participated in the clinic: 68.3% (n = 677) medical students, 10.1% (n = 100) physician assistant students, 9.7% (n = 96) undergraduate nursing students, 9.1% (n = 90) physical therapy students, and 2.8% (n = 28) nurse practitioner students. The majority (74.5%, n = 738) of student participants worked with students from other professions. More than 90% of students reported that faculty set a positive learning environment respectful of students. However, 20% of students reported that faculty could improve provision of constructive feedback. Direct Observation: Direct observation of core entrustable professional activities for medical students was possible. Senior medical students were more likely to be observed generating a differential diagnosis or management plan than first year medical students. CONCLUSIONS: Creation of a DOCENT clinic in the emergency department provided opportunities for interprofessional education and observation of student clinical skills, enriching student experience without compromising patient care.

Is it a match? a novel method of evaluating medical school success.

BACKGROUND: Medical education program evaluation allows for curricular improvements to both Undergraduate (UME) and Graduate Medical Education (GME). UME programs are left with little more than match rates and self-report to evaluate success of graduates in The Match. OBJECTIVE: This manuscript shares a novel method of program evaluation through a systematic assessment of Match outcomes. DESIGN: Surveys were developed and distributed to Program Training Directors (PTDs) at our institution to classify residency programs into which our UME graduates matched using an ordinal response scale and open-ended responses. Outcomes-based measures for UME graduates were collected and analyzed. The relationship between PTD survey data and UME graduates' outcomes were explored. Open-ended response data were qualitatively analyzed using iterative cycles of coding and identifying themes. RESULTS: The PTD survey response rate was 100%. 71% of our graduates matched to programs ranked as 'elite' (36%) or 'top' (35%) tier. The mean total number of 'Honors' grades achieved by UME graduates was 2.6. Data showed that graduates entering elite and top GME programs did not consistently earn Honors in their associated clerkships. A positive correlation was identified between USMLE Step 1 score, number of honors, and residency program rankings for a majority of the programs. Qualitative analysis identified research, faculty, and clinical exposure as necessary characteristics of 'elite' programs:. Factors considered by PTDs in the rating of programs included reputation, faculty, research, national presence and quality of graduates. CONCLUSIONS: This study describes a novel outcomes-based method of evaluating the success of UME programs. Results provided useful feedback about the quality of our UME program and its ability to produce graduates who match in highly-regarded GME programs. The findings from this study can benefit Clerkship Directors, Student Affairs and Curriculam Deans, and residency PTDs as they help students determine their competitiveness forspecialties and specific residency programs.

Efficacy and Safety of Low-Dose Iodine Plaque Brachytherapy for Juxtapapillary Choroidal Melanoma.

PURPOSE: To evaluate low- vs high-dose plaque brachytherapy for juxtapapillary choroidal melanoma. DESIGN: Retrospective interventional case series. METHODS: Setting: Single institution. STUDY POPULATION: Forty-seven patients with juxtapapillary choroidal melanoma. INTERVENTION: Iodine-125 plaque brachytherapy. Eyes were divided into apex low-dose (LD) and high-dose (HD) groups (≤ or > median apex dose 84.35 Gy). Main outcome measures were time to distant failure, local failure, death, enucleation, radiation retinopathy, optic neuropathy, and best-corrected visual acuity (BCVA). RESULTS: Freedom from distant failure rates were 96% and 95% in apex LD and HD groups at 5 years and 77% and 95% at 10 years, respectively (P = .84). Freedom from local failure rates were 90% in the apex LD group vs 89% in the HD group at 5 and 10 years (P = .96). Apex LD and HD groups did not differ for time to death or enucleation. Five- and 10-year freedom from radiation retinopathy and optic neuropathy rates were higher in the apex LD than HD group. Loss of ≥3 BCVA lines, final BCVA 20/40 or better, and final BCVA 20/200 or worse were more favorable in the 5 mm LD compared to HD group. Visual acuity outcomes did not differ between apex LD and HD groups. CONCLUSIONS: Low-dose iodine-125 plaque brachytherapy (67.5-81 Gy at tumor apex) provides safe and effective tumor control for juxtapapillary choroidal melanoma and may be associated with reduced radiation toxicity. Larger trials are needed to determine the optimal therapeutic dose for juxtapapillary choroidal melanoma.

Comparison of Visual Outcomes in Coats' Disease: A 20-Year Experience.

PURPOSE: To report differences in visual acuities among patients with Coats' disease who sought treatment at a tertiary care university-based practice. DESIGN: Single-center retrospective cohort study. PARTICIPANTS: Patients with Coats' disease diagnosed clinically, angiographically, or both from 1995 through 2015. METHODS: Patients were divided into 2 groups based on date of presentation: decade 1 (1995-2005) and decade 2 (2006-2015). MAIN OUTCOME MEASURES: Visual acuity (VA). RESULTS: Thirty-nine eyes of 39 patients were included with 19 eyes presenting in decade 1 and 20 eyes presenting in decade 2. Three patients demonstrated bilateral disease, but only the worse eye was included for analysis. Forty-seven percent of eyes in decade 1 demonstrated advanced stages of disease (stage 3B or worse) compared with 20% of eyes in decade 2. There was a trend for the mean initial presenting VA (±standard deviation) for decade 1 eyes to be worse (2.05±1.29 logarithm of the minimum angle of resolution [logMAR]) than for decade 2 eyes (1.45±0.99 logMAR; P = 0.1). From initial to final follow-up visit, mean VA also worsened for decade 1 eyes (P = 0.03), but remained stable for decade 2 eyes (P = 1.0). At the end of follow-up, there was a trend for mean VA for decade 1 eyes (2.28±1.17 logMAR) to be worse than for decade 2 eyes (1.60±1.15 logMAR; P = 0.07). Eight eyes were observed initially in decade 1 compared with 1 eye in decade 2, and only 1 of the observed eyes (in decade 2) developed painful glaucoma requiring enucleation. Decade 2 eyes had a higher average number of procedures per eye (6.5±4.9) compared with decade 1 eyes (1.4±1.7; P < 0.001). CONCLUSIONS: The earlier presentation of disease in decade 2 suggests improvements in disease detection over time. Furthermore, there was a trend for eyes to have better final VA in this decade. This is due to a combination of factors, including earlier presentation of disease, fewer eyes being observed without treatment, and eyes, when treated, receiving a higher number of procedures.

Anisometropia at Age 5 Years After Unilateral Intraocular Lens Implantation During Infancy in the Infant Aphakia Treatment Study.

PURPOSE: To report the prevalence of anisometropia at age 5 years after unilateral intraocular lens (IOL) implantation in infants. DESIGN: Prospective randomized clinical trial. METHODS: Fifty-seven infants in the Infant Aphakia Treatment Study (IATS) with a unilateral cataract were randomized to IOL implantation with an initial targeted postoperative refractive error of either +8 diopters (D) (infants 28 to <48 days of age) or +6 D (infants 48-210 days of age). Anisometropia was calculated at age 5 years. Six patients were excluded from the analyses. RESULTS: Median age at cataract surgery was 2.2 months (interquartile range [IQR], 1.2, 3.5 months). The mean age at the age 5 years follow-up visit was 5.0 ± 0.1 years (range, 4.9-5.4 years). The median refractive error at the age 5 years visit of the treated eyes was -2.25 D (IQR -5.13, +0.88 D) and of the fellow eyes +1.50 D (IQR +0.88, +2.25). Median anisometropia was -3.50 D (IQR -8.25, -0.88 D); range -19.63 to +2.75 D. Patients with glaucoma in the treated eye (n = 9) had greater anisometropia (glaucoma, median -8.25 D; IQR -11.38, -5.25 D vs no glaucoma median -2.75; IQR -6.38, -0.75 D; P = .005). CONCLUSIONS: The majority of pseudophakic eyes had significant anisometropia at age 5 years. Anisometropia was greater in patients that developed glaucoma. Variability in eye growth and myopic shift continue to make refractive outcomes challenging for IOL implantation during infancy.

Myopic Shift 5 Years after Intraocular Lens Implantation in the Infant Aphakia Treatment Study.

PURPOSE: To report the myopic shift at 5 years of age after cataract surgery with intraocular lens (IOL) implantation for infants enrolled in the Infant Aphakia Treatment Study (IATS). METHODS: Refractions were performed at 1 month and every 3 months postoperatively until age 4 years and then at ages 4.25, 4.5, and 5 years. The change in refraction over time was estimated by linear mixed model analysis. RESULTS: Intraocular lens implantation was completed in 56 eyes; 43 were analyzed (median age, 2.4 months; range, 1.0-6.8 months). Exclusions included 11 patients with glaucoma, 1 patient with Stickler syndrome, and 1 patient with an IOL exchange at 8 months postoperatively. The mean rate of change in a myopic direction from 1 month after cataract surgery to age 1.5 years was 0.35 diopters (D)/month (95% confidence interval [CI], 0.29-0.40 D/month); after age 1.5 years, the mean rate of change in a myopic direction was 0.97 D/year (95% CI, 0.66-1.28 D/year). The mean refractive change was 8.97 D (95% CI, 7.25-10.68 D) at age 5 years for children 1 month of age at surgery and 7.22 D (95% CI, 5.54-8.91 D) for children 6 months of age at surgery. The mean refractive error at age 5 years was -2.53 D (95% CI, -4.05 to -1.02). CONCLUSIONS: After IOL implantation during infancy, the rate of myopic shift occurs most rapidly during the first 1.5 years of life. Myopic shift varies substantially among patients. If the goal is emmetropia at age 5 years, then the immediate postoperative hypermetropic targets should be +10.5 D at 4 to 6 weeks and +8.50 D from 7 weeks to 6 months. However, even using these targets, it is likely that many children will require additional refractive correction given the high variability of refractive outcomes.

Update on congenital cataract surgery management.

PURPOSE OF REVIEW: The basic procedure of pediatric cataract surgery has not dramatically changed over the past few years. Recent multicenter study results along with technological innovations, however, have increased our understanding and armamentarium of techniques and devices used to improve outcomes. RECENT FINDINGS: We review surgical techniques that have been recently applied to the management of pediatric cataracts and describe newer intraocular lenses that have become available for use in the pediatric population. The 5-year results of the Infant Aphakia Treatment Study, including visual outcomes and complications, as well as other studies comparing intraocular lens implants with contact lenses for infants have shaped our management of congenital cataract. We also discuss how ocular imaging with optical coherence tomography has enhanced our understanding of the microstructural effects on pediatric eyes after cataract surgery and touch on other future innovations. SUMMARY: We review updates in the management of congenital cataract, which remains a major cause of preventable childhood blindness.

Temporary Lumbar Drain as Treatment for Pediatric Fulminant Idiopathic Intracranial Hypertension.

Fulminant idiopathic intracranial hypertension (FIIH) is a subtype of idiopathic intracranial hypertension (IIH) characterized by rapid, severe, progressive vision loss. Surgical intervention is often performed either as a cerebrospinal fluid (CSF) shunt procedure or an optic nerve sheath fenestration or, at times, both. These surgical procedures carry a significant risk of morbidity and failure. We present 2 patients in whom a temporary lumbar drain was successfully used in the management of medically undertreated pediatric FIIH, and circumvented the need for surgical intervention.

Comparison of the rate of refractive growth in aphakic eyes versus pseudophakic eyes in the Infant Aphakia Treatment Study.

PURPOSE: To compare the rate of refractive growth (RRG) between aphakic eyes and pseudophakic eyes in the Infant Aphakia Treatment Study (IATS). SETTING: Twelve clinical sites across the United States. DESIGN: Randomized clinical trial. METHODS: Patients randomized to unilateral cataract extraction with contact lens correction versus intraocular lens (IOL) implantation in the IATS had their rate of refractive growth (RRG3) calculated based on the change in refraction from the 1-month postoperative examination to age 5 years. The RRG3 is a logarithmic formula designed to calculate the RRG in children. Two-group t tests were used to compare the mean refractive growth between the contact lens group and IOL group and outcomes based on age at surgery and visual acuity. RESULTS: Longitudinal refractive data were studied for 108 of 114 patients enrolled in the IATS (contact lens group, n = 54; IOL group, n = 54). The mean RRG3 was similar in the contact lens group (-18.0 diopter [D] ± 11.0 [SD]) and the IOL group (-19.0 ± 9.0 D) (P = .49). The RRG3 value was not correlated with age at cataract surgery, glaucoma status, or visual outcome in the IOL group. In the aphakia group, only visual outcome was correlated with refractive growth (P = .01). CONCLUSIONS: Infants' eyes had a similar rate of refractive growth after unilateral cataract surgery whether or not an IOL was implanted. A worse visual outcome was associated with a higher RRG in aphakic, but not pseudophakic, eyes.

Mystery behind the match: an undergraduate medical education-graduate medical education collaborative approach to understanding match goals and outcomes.

BACKGROUND: There is a paucity of information regarding institutional targets for the number of undergraduate medical education (UME) graduates being matched to graduate medical education (GME) programs at their home institutions. At our institution, the Duke University, the number of UME graduates matched to GME programs declined dramatically in 2011. To better understand why this decline may have happened, we sought to identify perceived quality metrics for UME and GME learners, evaluate trends in match outcomes and educational program characteristics, and explore whether there is an ideal retention rate for UME graduates in their home institutions' GME programs. METHODS: We analyzed the number of Duke University UME graduates remaining at Duke for GME training over the past 5 years. We collected data to assess for changing characteristics of UME and GME, and performed descriptive analysis of trends over time to investigate the potential impact on match outcomes. RESULTS: A one-sample t-test analysis showed no statistically significant difference in the number of Duke UME graduates who stayed for GME training. For both UME and GME, no significant changes in the characteristics of either program were found. DISCUSSION: We created a process for monitoring data related to the characteristics or perceived quality of UME and GME programs and developed a shared understanding of what may impact match lists for both UME graduates and GME programs, leaving the Match somewhat less mysterious. While we understand the trend of graduates remaining at their home institutions for GME training, we are uncertain whether setting a goal for retention is reasonable, and so some mystery remains. We believe there is an invaluable opportunity for collaboration between UME and GME stakeholders to facilitate discussion about setting shared institutional goals.

In vitro characteristics of Tenon's fibroblast lines derived from pediatric and adult eyes do not fully explain pediatric glaucoma surgery failure: a preliminary report.

PURPOSE: To compare the in vitro characteristics of Tenon's capsule fibroblasts from children and adults that may be relevant to filtration surgery success. METHODS: Fibroblast cell lines derived from 5 young (median patient age, 2.4 years) and 7 old (median patient age, 71 years) discarded Tenon's capsule surgical specimens were used at early passage (P2-P3). Fibroblasts were plated at "high" (10(4)cells/cm(2)) or "low" density (10(3)cells/cm(2)) and harvested at days 0-14, for growth curve and doubling time comparisons. Migration was measured using a wound model (confluent monolayers ± 5-fluorouracil [5-FU] over 1-96 hours). Collagen synthesis was measured as secreted hydroxyproline/24 hours from confluent monolayers. RESULTS: At low density, "young" fibroblasts achieved higher cell numbers at confluence (day 14) compared with "old": 158 ± 35 versus 105 ± 12 × 10(3)cells/cm(2) (P = 0.0034). Mean doubling time for young versus old was similar at low density plating: 20.95 ± 1.55 versus 22.37 ± 2.09 hours (P = 0.26). It was shorter, however, for young versus old at high-density plating: 42.11 ± 6.01 versus 54.26 ± 4.24 hours (P = 0.0051). Wound closure rates were similar for young versus old cells (4 lines for each group) with and without 5-FU. Collagen synthesis was similar for young and old (4 lines for each group). CONCLUSIONS: Although young fibroblasts reached higher density than old at confluence and had shorter doubling times at high-density plating, wound closure/migration and collagen synthesis rates were similar. Despite the preliminary nature of this study (few specimens, limited cell features explored), factors besides those intrinsic to the fibroblasts themselves likely mediate the more rapid healing/scarring after glaucoma filtration surgery in children.

Low cerebrospinal fluid protein in prepubertal children with idiopathic intracranial hypertension.

PURPOSE: To evaluate a clinical observation that prepubertal children with idiopathic intracranial hypertension (IIH) have low cerebrospinal fluid (CSF) protein levels compared to healthy children and pubertal patients with IIH. METHODS: The medical records of prepubertal and pubertal IIH patients and controls seen in the pediatric neuro-ophthalmology clinic at Duke between 2003 and 2013 were retrospectively reviewed. The control group consisted of children who had normal intracranial pressure on lumbar puncture performed to evaluate for headaches or anomalous-looking optic nerves. The records were analyzed with attention to demographic characteristics, clinical presentation, course, and lumbar puncture results. RESULTS: A total of 23 prepubertal children with IIH (age range, 0.75-13 years), 16 pubertal patients with IIH (age range, 13-21 years), and 12 controls (age range 3-14 years) were included. CSF analysis revealed that prepubertal children with IIH had significantly lower CSF protein levels (17.3 ± 5.7 mg/dL) compared to pubertal subjects with IIH (23.4 ± 8.4 mg/dL; P = 0.019) or healthy controls (23.5 ± 6.4 mg/dL; P = 0.011). Furthermore, 9 of 23 prepubertal IIH patients (39%) had abnormally low CSF protein level (<15 mg/dL), compared to zero pubertal IIH patients (P = 0.005) and zero controls (P = 0.015). Acetazolamide increased CSF protein level in 100% of patients who underwent repeat lumbar puncture after starting the medication (average increase, 10.3 ± 6.6 mg/dL). CONCLUSIONS: Low CSF protein level may have diagnostic utility as a biomarker for prepubertal IIH. Furthermore, this finding suggests that some cases of prepubertal IIH may be caused by CSF overproduction rather than decreased CSF resorption.
