Physician-patient racial concordance and disparities in birthing mortality for newborns.

Recent work has emphasized the benefits of patient-physician concordance on clinical care outcomes for underrepresented minorities, arguing it can ameliorate outgroup biases, boost communication, and increase trust. We explore concordance in a setting where racial disparities are particularly severe: childbirth. In the United States, Black newborns die at three times the rate of White newborns. Results examining 1.8 million hospital births in the state of Florida between 1992 and 2015 suggest that newborn-physician racial concordance is associated with a significant improvement in mortality for Black infants. Results further suggest that these benefits manifest during more challenging births and in hospitals that deliver more Black babies. We find no significant improvement in maternal mortality when birthing mothers share race with their physician.

Erdheim-Chester disease and vemurafenib: a review of ophthalmic presentations and clinical outcomes.

PURPOSE: To provide a comprehensive review of ocular and orbital manifestations of Erdheim-Chester Disease (ECD) and compare clinical outcomes with vemurafenib (INN) to historical treatments (HT). Primary outcomes are ophthalmic findings on presentation, changes in visual acuity, and mortality rate. Secondary outcomes include the progression of ocular findings, systemic involvements, and treatment modalities. METHODS: All published literature from January 1983 to March 2021 was searched for ophthalmic manifestations of ECD. Clinical outcomes following HT were collected and compared with INN. RESULTS: Forty-seven patients with ECD and ophthalmic presentations were identified. The mean age was 49.6 years (SD = 15.0). Proptosis (65.6%) and extraocular muscle restrictions (42.5%) were the most common presenting signs. Of 41 (87.2%) patients with orbital masses on radiologic examination, 90.2% were bilateral, and 53.7% were located in the intraconal space. Ophthalmic examination was significant for xanthelasma (27.2%), optic disc edema (34.0%), and subretinal changes (21.3%). Common treatments were systemic steroids (76.6%), interferon-α (17.0%), and cyclophosphamide (14.9%). INN was less commonly used (12.8%). The mean change in logMAR visual acuity declined with HT (29.9%) but improved with INN (79.1%) (p > 0.05). The proportion of eyes with complete vision loss increased after HT (p < 0.05). The overall mortality rate was 27.7% and notably higher in the HT group (29.3%) when compared to the INN group (16.7%) (p > 0.05). CONCLUSION: ECD presents with many ophthalmic manifestations. Although the intraocular treatments remain controversial, INN should be highly considered in treating orbital ECD patients with BRAF-V600E mutations to prevent and reverse vision loss.

Intralesional corticosteroid injections to treat lip swelling associated with oral Crohn's disease in a child.

This procedural report details the case of a 10-year-old boy with oral Crohn's disease successfully treated with intralesional corticosteroid injections. The intervention used topical anesthesia with a eutectic mixture of lidocaine 2.5%/prilocaine 2.5% cream followed by intralesional triamcinolone acetonide. This approach safely and effectively reduced patient discomfort while allowing for an acceptable and durable clinical outcome.

Patient-physician gender concordance and increased mortality among female heart attack patients.

We examine patient gender disparities in survival rates following acute myocardial infarctions (i.e., heart attacks) based on the gender of the treating physician. Using a census of heart attack patients admitted to Florida hospitals between 1991 and 2010, we find higher mortality among female patients who are treated by male physicians. Male patients and female patients experience similar outcomes when treated by female physicians, suggesting that unique challenges arise when male physicians treat female patients. We further find that male physicians with more exposure to female patients and female physicians have more success treating female patients.

Investors prefer entrepreneurial ventures pitched by attractive men.

Entrepreneurship is a central path to job creation, economic growth, and prosperity. In the earliest stages of start-up business creation, the matching of entrepreneurial ventures to investors is critically important. The entrepreneur's business proposition and previous experience are regarded as the main criteria for investment decisions. Our research, however, documents other critical criteria that investors use to make these decisions: the gender and physical attractiveness of the entrepreneurs themselves. Across a field setting (three entrepreneurial pitch competitions in the United States) and two experiments, we identify a profound and consistent gender gap in entrepreneur persuasiveness. Investors prefer pitches presented by male entrepreneurs compared with pitches made by female entrepreneurs, even when the content of the pitch is the same. This effect is moderated by male physical attractiveness: attractive males were particularly persuasive, whereas physical attractiveness did not matter among female entrepreneurs.

Melanoma Treatments: Advances and Mechanisms.

Advances in the understanding of the molecular pathogenesis of melanoma and in cancer immunology have led to the rational design and recent clinical implementation of a variety of novel therapies for metastatic melanoma. BRAF and MEK inhibitors that target the MAPK pathway have high rates of clinical response in BRAF-mutant melanoma. Therapies that modulate the immune response to melanoma, including monoclonal antibodies that interfere with pathways that inhibit T-cell function, have been shown to be effective in melanoma. Lessons learned from these encouraging results are driving the development of new treatments for melanoma and other cancers. This review will focus on the science and clinical findings related to targeted therapies that inhibit BRAF or MEK as well as the immunotherapies that block the CTLA-4 or PD-1 pathways. Other experimental and combinatorial therapeutic approaches will also be discussed.

Vitrectomy for floaters: prospective efficacy analyses and retrospective safety profile.

PURPOSE: Floaters impact vision but the mechanism is unknown. We hypothesize that floaters reduce contrast sensitivity function, which can be normalized by vitrectomy, and that minimally invasive vitrectomy will have lower incidences of retinal tears (reported at 30%) and cataracts (50-76%). METHODS: Seventy-six eyes (34 phakic) with floaters were evaluated in 2 separate studies. Floater etiologies were primarily posterior vitreous detachment in 61 of 76 eyes (80%) and myopic vitreopathy in 24 of 76 eyes (32%). Minimally invasive 25G vitrectomy was performed without posterior vitreous detachment induction, leaving anterior vitreous, and using nonhollow probes for cannula extraction. Efficacy was studied prospectively (up to 9 months) in 16 floater cases with Freiburg Acuity Contrast Testing (Weber index [%W] reproducibility = 92.1%) and the National Eye Institute Visual Function Questionnaire. Safety was separately evaluated in 60 other cases followed up on an average of 17.5 months (range, 3-51 months). RESULTS: Floater eyes had 67% contrast sensitivity function attenuation (4.0 ± 2.3 %W; control subjects = 2.4 ± 0.9 %W, P < 0.013). After vitrectomy, contrast sensitivity function normalized in each case at 1 week (2.0 ± 1.4 %W, P < 0.01) and remained normal at 1 month (2.0 ± 1.0 %W, P < 0.003) and 3 months to 9 months (2.2 ± 1.5 %W, P < 0.018). Visual Function Questionnaire was 28.3% lower in floater patients (73.2 ± 15.6, N = 16) than in age-matched control subjects (93.9 ± 8.0, N = 12, P < 0.001), and postoperatively improved by 29.2% (P < 0.001). In the safety study of 60 floater cases treated with vitrectomy, none developed retinal breaks, infection, or glaucoma after a mean follow-up of 17.5 months. Only 8 of 34 cases (23.5%) required cataract surgery (none younger than 53 years) at an average of 15 months postvitrectomy. CONCLUSION: Floaters lower contrast sensitivity function, which normalizes after vitrectomy. Visual Function Questionnaire quantified improvement in satisfaction. Not inducing posterior vitreous detachment reduced retinal tear incidence from 30% to 0% (P < 0.007). Postvitrectomy cataract incidence was reduced from 50% to 23.5% (P < 0.02). This approach thus seems effective and safe in alleviating the visual dysfunction induced by floaters.

Ventriculoperitoneal shunt as a treatment of visual loss in idiopathic intracranial hypertension.

BACKGROUND: The aims of this study were to evaluate visual function outcomes in idiopathic intracranial hypertension (IIH) patients who underwent ventriculoperitoneal (VP) shunt for visual loss and to determine a VP shunt survival curve over time. METHODS: A retrospective medical record review was performed of all new IIH patients first evaluated at our institution who underwent VP shunt placement over a 7-year period (2004-2010). There were 2 primary outcome measures: the first being visual acuity (VA) and the second being shunt survival. Patients who received VP shunt for visual loss were included in the visual outcome analysis, and all patients who received VP shunt for any reason were included in the shunt survival analysis. RESULTS: Of the 338 new patients with IIH, 19 patients (6%) met the inclusion criteria and 17 underwent VP shunt for visual loss and 2 for headaches. Average follow-up was 21.2 months (range, 5-1,342 days). Of the 17 patients who had VP shunt for visual loss, 5 patients had optic nerve sheath fenestration (ONSF) surgery before VP shunt, and 1 patient had bilateral ONSF surgery after VP shunt. Median VA before shunt was 20/200 in the worse eye (range, 20/20 to NLP) and 20/40 in the better eye (20/20 to HM). Median VA after shunt was 20/60 in the worse eye (20/20 to lumboperitoneal) and 20/30 in the better eye (20/20 to 20/800). The improvement in VA was statistically significant in both worse eyes (P = 0.002, Wilcoxon signed-rank test) and better eyes (P = 0.028). The mean automated visual field (AVF) mean deviation (MD) of available AVFs before shunt was 223.36 dB (range, 233.38 to 27.01 dB) for the worse eye (n = 11) and 219.66 dB (230.11 to 25.91 dB) for the better eye (n = 11). Mean AVF MD deviation of available AVFs after shunt was 220.68 dB (232.13 to 23.97 dB) for the worse eye (n = 11) and 216.35 dB (232.13 to 21.00 dB) for the better eye (n = 11): this improvement was not significant (P = 0.27, P = 0.26, respectively). Independent masked record reviews by 3 neuro-ophthalmologists showed that 9 (53%) patients improved, 5 (29%) unchanged, 1 (6%) worsened, and 2 (12%) were indeterminate. Kaplan-Meier analysis showed a persistent steady decrease of functioning VP shunts over the entire period of 36 months with 80%, 65%, and 48% of VP shunts functioning without replacement, removal, or revision at 12, 24, and 36 months, respectively. CONCLUSION: VP shunts improve or stabilize most IIH patients presenting with severe progressive visual loss or those with visual loss refractive to medical treatment and ONSF. Survival analysis shows persistent decrease of functioning shunts over time.

Diagnostic Role of Oral Fluorescein Angiography in Pediatric Ambulatory Clinics.

Oral ingestion of fluorescein can be done in ambulatory pediatric clinics. We show that oral ultra-widefield fluorescein angiography is a non-invasive approach to rapidly diagnose and manage a diverse set of pediatric retinal vascular diseases.

Sociodemographic and Visual Outcomes of Juvenile Idiopathic Arthritis Uveitis: IRIS® Registry Study.

Purpose: Understanding sociodemographic factors associated with poor visual outcomes in children with juvenile idiopathic arthritis-associated uveitis may help inform practice patterns. Patients and Methods: Retrospective cohort study on patients <18 years old who were diagnosed with both juvenile idiopathic arthritis and uveitis based on International Classification of Diseases tenth edition codes in the Intelligent Research in Sight Registry through December 2020. Surgical history was extracted using current procedural terminology codes. The primary outcome was incidence of blindness (20/200 or worse) in at least one eye in association with sociodemographic factors. Secondary outcomes included cataract and glaucoma surgery following uveitis diagnosis. Hazard ratios were calculated using multivariable-adjusted Cox proportional hazards models. Results: Median age of juvenile idiopathic arthritis-associated uveitis diagnosis was 11 (Interquartile Range: 8 to 15). In the Cox models adjusting for sociodemographic and insurance factors, the hazard ratios of best corrected visual acuity 20/200 or worse were higher in males compared to females (HR 2.15; 95% CI: 1.45-3.18), in Black or African American patients compared to White patients (2.54; 1.44-4.48), and in Medicaid-insured patients compared to commercially-insured patients (2.23; 1.48-3.37). Conclusion: Sociodemographic factors and insurance coverage were associated with varying levels of risk for poor visual outcomes in children with juvenile idiopathic arthritis-associated uveitis.

The role of exercise in aromatase inhibitor-induced arthralgia.

Aromatase inhibitors are prescribed in breast cancer due to their associated lower rate of cancer recurrence compared to tamoxifen. However, aromatase inhibitor-induced arthralgia (AIIA) is one of the leading causes of treatment nonadherence, increasing the risk of cancer recurrence. The pathophysiology of AIIA is poorly understood, and although current recommendations for AIIA include lifestyle changes and analgesics depending on the severity of symptoms, there is no established effective treatment. The aim of this study is to explore the presentation and mechanism of AIIA and investigate the feasibility and efficacy of different exercise interventions (aerobic, resistance, aerobic and resistance combined, and yoga or tai chi) in patients with AIIA to guide the development of formal exercise prescription guidelines. Findings indicate that a mixed-modality regimen of aerobic and resistance exercises is feasible and safe and may serve the most benefit in improving joint pain, functionality, and quality of life. More specifically, the weekly regimen should consist of 150 min of aerobic exercise with two sessions of at least six resistance exercises, 8 to 12 repetitions, three sets each. Supplementary yoga and tai chi may be recommended twice a week depending on a patient's target symptoms. Yoga was associated with improved physical functionality, whereas tai chi was related to improvements in mental health. However, the feasibility and impact of combined aerobic and resistance exercise protocols with yoga or tai chi in our target population were not investigated in this review. The use of large, randomized controlled trials is recommended for future studies.

Hallermann-Streiff Syndrome in Concordant Monozygotic Twins With Congenital Cataracts, Exudative Retinal Detachments, and One Case of Corneal Perforation Requiring Keratoplasty.

PURPOSE: We describe the management of Hallermann-Streiff syndrome in monozygotic female twins with congenital cataracts, exudative retinal detachments, and 1 case of corneal descemetocele with associated dellen and subsequent perforation. METHODS: This study was a case report and review of the literature. RESULTS: Twins 1 and 2 exhibited all 7 cardinal characteristics of Hallermann-Streiff syndrome, presenting with spontaneous lenticular resorption, anterior uveitis, and glaucoma. They underwent bilateral cataract extraction with near total capsulectomy. Both twins experienced recurrent glaucoma, for which twin 1 underwent successful endocyclophotocoagulation in both eyes and twin 2 in the left eye alone. The fellow eye developed 2 sites of perilimbal corneal descemetoceles with associated dellen at the inferotemporal limbal corneal junction leading to spontaneous perforation of 1 site, requiring a full-thickness corneal graft. Both twins developed recurrent bilateral exudative retinal detachments unresponsive to oral prednisolone. Twin 1's last best-corrected visual acuity with aphakic spectacles was 20/260 in the right eye and 20/130 in the left eye at age 4 years and 8 months. Twin 2's last best-corrected visual acuity was 20/130 in each eye at age 4 years and 11 months, over a year after right eye penetrating keratoplasty. CONCLUSIONS: We describe 2 rare cases of Hallermann-Streiff syndrome in monozygotic twins complicated by corneal perforation requiring penetrating keratoplasty in 1 eye of 1 twin. Although corneal opacities have been described in this condition, this is the first case of corneal descemetocele in Hallermann-Streiff syndrome. The cornea was stabilized with a relatively favorable visual outcome over 1 year later.

Referral patterns for infantile cataracts in two regions of the United States.

BACKGROUND: Delayed treatment of congenital or infantile cataracts can cause deprivation amblyopia. Prompt diagnosis and surgical intervention is critical for optimal outcomes. This study assessed referral patterns for congenital or infantile cataracts in two regions of the United States. METHODS: The medical records of children 0-1 years of age with congenital or infantile cataracts at Stanford University (2008-2018) and Emory University (2010-2015) were reviewed retrospectively. RESULTS: A total of 111 children were included. Of these, 82 (74%) were initially evaluated by a primary care doctor, of whom 40 (49%) were referred directly to a pediatric cataract surgeon. Of 61 newborns 0-2 months of age, 9 (15%) were initially referred to an eye care provider before 6 weeks of age, but the initial evaluation by a pediatric cataract surgeon was delayed until after 6 weeks of age. Referral patterns were similar between the two institutions (P = 0.06). CONCLUSIONS: Many children with congenital of infantile cataracts are initially referred by a primary care doctor to an eye care provider who does not perform pediatric cataract surgery. Nevertheless, the majority of newborn infants with cataracts were evaluated by a pediatric cataract surgeon before 6 weeks of age.

Selective sentinel lymph node dissection for melanoma: importance of harvesting nodes with lower radioactive counts without the need for blue dye.

BACKGROUND: Determining how many sentinel lymph nodes (SLNs) should be removed for melanoma is important. The purpose of this study is to determine the frequency at which nodes that are less radioactive than the "hottest" node (which is negative) are positive for melanoma, how low of a radioactivity should warrant harvest, and if isosulfan blue is necessary. METHODS: We reviewed 1,152 melanoma patients who underwent lymphoscintigraphy with technetium, with or without blue dye, and SLN dissection from 1996 to 2008. SLNs with radioactivity ≥10% of the "hottest" SLN, all blue nodes, and all suspicious nodes were removed and analyzed. The miss rate was calculated as the proportion of node positive cases in which the "hottest" SLN was negative. RESULTS: SLNs were identified in 1,520 nodal basins in 1,152 patients. SLN micrometastases were detected in 218 basins (14%) in 204 patients (18%). In 16% of SLN-positive patients (33/204 patients), the positive SLN was found to have a lower radioactive count than the "hottest" SLN, which was negative. In 21 of these cases, the positive SLNs had radioactivity ≤50% of the "hottest" SLN. The 10% rule significantly reduced the miss rate to 2.5% compared with removal of only the "hottest" SLN (miss rate = 16%). Also, blue dye did not significantly decrease the miss rate compared with radiocolloid alone using the 10% rule. CONCLUSIONS: To decrease the miss rate, all SLNs with ≥10% of the ex vivo radioactivity of the "hottest" SLN should be removed and blue dye is not essential.

Microphthalmia and orbital cysts in DiGeorge syndrome.

We report the case of a 4-month-old boy diagnosed with DiGeorge syndrome with novel ocular features. The patient was diagnosed through genetic testing, with a noted 22q11.2 deletion, and had the additional clinical findings of cardiac anomalies, Hirschsprung's disease, and intracranial microhemorrhages. Eye findings included bilateral microphthalmia, persistent fetal vasculature, chorioretinal coloboma, and a unilateral orbital cyst. Given no known additional inciting exposures, a dysgenic mechanism resulting in failed closure of developmental fissures associated with the chromosomal deletion likely gave rise to these combined pathologies.

Health literacy and patient activation among adults with chronic diseases in Singapore: A cross-sectional study.

AIMS: Increased patient activation levels can improve health outcomes. Hence, this study aims to examine the relationships between sociodemographic variables and domain-specific health literacies with patient activation. DESIGN: A cross-sectional design. METHODS: 200 outpatient adults with chronic diseases completed a survey that assessed their domain-specific health literacy and patient activation levels. Univariate and multivariate analysis of the variables were conducted on patient activation with 95% confidence interval (CI). RESULTS: Multiple linear regression analyses observed a positive linear relationship between the following domain-specific health literacy variables-"actively manage my health" (p < .0001, 95% CI: 0.89-2.29), "understanding health information" (p = .008, 95% CI: 0.28-1.85), and "finding good health information" (p = .02, 95% CI 0.13-1.51) with patient activation. The other sociodemographic and clinical variables were not statistically significant. Increased focus from healthcare professionals is needed on helping patients better find and understand health information and encouraging them to actively manage their health; elements which would raise their activation levels.

Extended Neuralgic Amyotrophy Syndrome in a Confirmed COVID-19 Patient After Intensive Care Unit and Inpatient Rehabilitation Stay.

ABSTRACT: The cause of neuralgic amyotrophy is often unknown but is commonly associated with a recent upper respiratory viral tract infection. Since the beginning of the COVID-19 pandemic, there has been a tireless effort to understand the sequelae of the virus. A 46-yr-old woman who presented after a COVID-19 hospitalization complicated by hypoxic respiratory failure requiring intubation and mechanical ventilation for 23 days was subsequently found to have lower limb sensorium changes as well as upper limb weakness. Left shoulder abduction and extension were both 3/5 in motor strength, and left hip flexion strength was 4/5 with diminished sensation to crude touch in the left lateral thigh. Nerve conduction studies and electromyography findings included a mild left median neuropathy at the wrist and motor unit recruitment pattern consistent with a chronic left upper trunk plexopathy with reinnervation. The case presented describes an extended neuralgic amyotrophy syndrome from an atraumatic mechanism in a previously diagnosed COVID-19 patient. An extended neuralgic amyotrophy syndrome has at least three immune mediated etiologies postulated (1) direct neuropathogenicity, (2) molecular mimicry, and (3) direct cytotoxic effects on peripheral nerves. As COVID-19 survivors continue to be seen in outpatient settings, practitioners should remain aware of diffuse neurological complications as sequelae of the virus persist.

Virtually Possible: Medical Student Rehabilitation Rotations During a Pandemic.

ABSTRACT: The novel coronavirus 2019 pandemic has led to new dilemmas in medical education because of an initial shortage of personal protective equipment, uncertainty regarding disease transmission and treatments, travel restrictions, and social distancing guidelines. These new problems further compound the already existing problem of limited medical student exposure to the field of physical medicine and rehabilitation, particularly for students in medical schools lacking a department of physical medicine and rehabilitation, approximately 50% of medical schools. A virtual medical student physical medicine and rehabilitation rotation was created to mitigate coronavirus 2019-related limitations and impact on medical education. Using audiovisual technology, students had the opportunity to participate in clinical inpatient and outpatient care, live-streamed procedures, and virtual didactics, develop and showcase their clinical knowledge and reasoning skills, and become familiar with the culture of the physical medicine and rehabilitation residency program. Adaptive educational approaches, including integration of the flipped classroom model, success, pitfalls, and areas for improvement will be described and discussed. Providing nontraditional methods for physical medicine and rehabilitation education and exposure to medical students is crucial to maintain and promote growth of the field in this unprecedented and increasingly virtual era.
