A unique case of orbital inflammatory syndrome following COVID-19 infection.

Orbital inflammatory disease is a rarely reported complication of COVID-19 infection. We report a unique case of bilateral orbital myositis in a 12-year-old boy who tested positive for COVID-19 without typical systemic symptoms. Workup for other infectious and inflammatory etiologies was negative. After failing both oral and intravenous antibiotics, the patient was started on high-dose systemic steroids, with significant clinical improvement after 24 hours, thus confirming the inflammatory etiology of his presentation.

Update on the Treatment of Retinoblastoma.

Retinoblastoma (Rb) is the most common pediatric ocular malignancy and accounts for 2% of all childhood cancers. Rb is initiated by a mutation of the RB1 tumor suppressor gene and occurs in 2 forms: 1) unilateral and unifocal, characterized by a single tumor in 1 eye, and 2) bilateral or unilateral, multifocal Rb with multiple tumor foci in 1 or both eyes. Rb is a disease of young children and if left untreated can result in visual morbidity as well as systemic mortality. Fortunately, because of the greater availability of genetic testing and earlier diagnosis, novel targeted therapies, and multimodal treatment approaches, disease-free survival rates and visual prognoses have improved dramatically. Current efforts to expand the accessibility of the newest Rb treatments aim to improve Rb outcomes worldwide. In this article, we will review the clinical presentation, diagnosis, and management of Rb, with a focus on the newest treatment approaches.

A rare case of pediatric Tolosa-Hunt syndrome.

Tolosa-Hunt syndrome is a rare disorder characterized by granulomatous inflammation involving the cavernous sinus, superior orbital fissure, and/or orbit with no additional underlying cause. Tolosa-Hunt syndrome most often presents with painful ophthalmoplegia involving one or multiple cranial nerves. Here we report the case of an 8-year-old girl who presented, atypically, without the hallmark finding of pain. This case of pediatric Tolosa-Hunt syndrome is the only reported example to date lacking what is considered its pathognomonic feature and thus brings to light the clinical variability of this already inconspicuous disorder.

The Utility of Postoperative Computed Tomography Imaging Following Isolated Orbital Blowout Fracture Repair.

PURPOSE: To determine the clinical utility of computed tomography (CT) imaging following isolated orbital blowout fracture (OBF) repair. METHODS: Single-center retrospective review of adult patients undergoing surgical repair of isolated OBFs between November 2008 and August 2016 who received postoperative CT scans. Preoperative and postoperative examination data, postoperative imaging reads, postoperative courses, and any reoperation documentation were collected from electronic medical records. Postoperative imaging findings were categorized as major, indeterminate, or minor by predicted impact on clinical management. Major findings indicated a need for reoperation, indeterminate a potential reoperation, and minor no reoperation. RESULTS: Fifty-two cases met inclusion criteria: 94.2% (n = 49) of postoperative scans included minor findings, 34.6% (n = 18) indeterminate findings, and 19.2% (n = 10) major findings. Three patients returned to the operating room (OR) for surgical revision. All 3 had a significant and concerning change on postoperative examination. Only 1 also had a major finding on postoperative imaging. The remaining 49 patients had benign postoperative examinations, despite 9 (17.3%) with major imaging findings who did not undergo reoperation. CONCLUSIONS: In the majority of OBF repairs, postoperative CT scan findings were not predictive of a need to return to the OR for revision. Reoperation was instead largely prompted by concerning changes in the postoperative clinical examination. Our findings suggest that postoperative imaging in the absence of clinical concern should not be included in the surgical management of isolated OBFs. Instead, targeted imaging will help reduce radiation exposure and health-care costs without sacrificing patient care.

Outpatient Surgical Management of Orbital Blowout Fractures.

There is ample investigation into the optimal timing and approach to orbital blowout fracture (OBF) repair; however, less attention has been directed toward postoperative care. This is a multicenter IRB-approved retrospective review of patients with OBF presenting to our study sites between November 2008 and August 2016. Those with isolated OBF, over 18 years of age, and who had not suffered additional facial injuries or globe trauma were included. A total of 126 surgical cases of isolated OBF repair were identified that met our inclusion and exclusion criteria; 42.1% were outpatient repairs while the remaining 57.9% were admitted for overnight monitoring. Time elapsed prior to repair differed between the two groups at a mean of 8.4 days versus 5.2 days for the outpatient and inpatient cohorts, respectively ( p = 0.001). A majority of inpatient cases underwent immediate repair, while a majority of outpatient cases were delayed. There were two cases of RBH in the outpatient cohort resulting in an overall incidence of 1.6%. In both instances, a significant change in clinical exam including decreased visual acuity, diplopia, and eye pain prompted repeat evaluation and immediate intervention for hematoma evacuation. Estimated hospital charges to the patient's insurance for key components of an inpatient versus outpatient isolated OBF repair amounted to a total cost of $9,598.22 for inpatient management and $7,265.02 for outpatient management without reflexive postoperative imaging. Reflexive postoperative CT scans were obtained in 76.7% of inpatient cases and only two led to a reoperation. No outpatient repairs included reflexive postoperative imaging. Outpatient OBF repair is an attractive alternative to inpatient management. The potential cost savings of outpatient management of OBF, which do not detract from quality or safety of patient care, should not be ignored. Our results will hopefully contribute to updated shared practice patterns for all subspecialties that participate in the surgical management of OBF.

Depression, Anxiety, and Stress in Parents of Patients With Retinoblastoma.

PURPOSE: To assess depression, anxiety, and stress in parents of patients with retinoblastoma and to evaluate the impact of unifocal vs multifocal retinoblastoma. METHODS: A cross-sectional, self-reported psychological assessment of parents of patients with retinoblastoma at a tertiary care ocular oncology center was performed. The Beck Depression Inventory-II (BDI), Beck Anxiety Inventory (BAI), The Parental Stress Index 4-Short Form, and a retinoblastoma Knowledge Assessment questionnaire were administered. Descriptive statistics for outcomes and comparative analyses were made. RESULTS: There were 138 parents of children with retinoblastoma (unifocal: n = 77, multifocal: n = 61). Overall, parents displayed mild, moderate, or severe depression (BDI) (n = 37, 26.7%); mild, moderate, or severe anxiety (BAI) (n = 49, 35.8%), and stress scores within normal limits (n = 138, 100%). A comparison (unifocal vs multifocal) revealed parents of children with multifocal retinoblastoma with severe depression (1.4% vs 10.2%, P < .02), and no differences in anxiety or stress. Factors associated with moderate or severe parental depression included previous history of depression (30.0% vs 3.9%, P < .001) and factors for moderate or severe anxiety included previous history of depression (33.3% vs 8.6%, P < .001), parent highest level of education at high school or less vs college or beyond (29.2% vs 10.9%, P = .031), and parental report of "child developmental delay" (31.5% vs 11.3%, P = .019). CONCLUSIONS: The majority of parents displayed minimal depression (73.3%), anxiety (64.2%), or stress (100%). However, severe depression is more often found in those whose children have multifocal disease, and previous history of depression and less education can impact psychological function.

Mitochondrial Haplogroups Modify the Effect of Diabetes Duration and HbA1c on Proliferative Diabetic Retinopathy Risk in Patients With Type 2 Diabetes.

Purpose: We previously demonstrated an association between European mitochondrial haplogroups and proliferative diabetic retinopathy (PDR). The purpose of this study was to determine how the relationship between these haplogroups and both diabetes duration and hyperglycemia, two major risk factors for diabetic retinopathy (DR), affect PDR prevalence. Methods: Our population consisted of patients with type 2 diabetes with (n = 377) and without (n = 480) DR. A Kruskal-Wallis test was used to compare diabetes duration and hemoglobin A1c (HbA1c) among mitochondrial haplogroups. Logistic regressions were performed to investigate diabetes duration and HbA1c as risk factors for PDR in the context of European mitochondrial haplogroups. Results: Neither diabetes duration nor HbA1c differed among mitochondrial haplogroups. Among DR patients from haplogroup H, longer diabetes duration and increasing HbA1c were significant risk factors for PDR (P = 0.0001 and P = 0.011, respectively). Neither diabetes duration nor HbA1c was a significant risk factor for PDR in DR patients from haplogroup UK. Conclusions: European mitochondrial haplogroups modify the effects of diabetes duration and HbA1c on PDR risk in patients with type 2 diabetes. In our patient population, longer diabetes duration and higher HbA1c increased PDR risk in patients from haplogroup H, but did not affect PDR risk in patients from haplogroup UK. This relationship has not been previously demonstrated and may explain, in part, why some patients with nonproliferative DR develop PDR and others do not, despite similar diabetes duration and glycemic control.

Mitochondrial Haplogroups Affect Severity But Not Prevalence of Diabetic Retinopathy.

Purpose: We previously reported European mitochondrial haplogroup H to be a risk factor for and haplogroup UK to be protective against proliferative diabetic retinopathy (PDR) among Caucasian patients with diabetic retinopathy (DR). The purpose of this study was to determine whether these haplogroups are also associated with the risk of having DR among Caucasian patients with diabetes. Methods: Deidentified medical records for 637 Caucasian patients with diabetes (223 with DR) were obtained from BioVU, Vanderbilt University's electronic, deidentified DNA databank. An additional 197 Caucasian patients with diabetes (98 with DR) were enrolled from the Vanderbilt Eye Institute (VEI). We tested for an association between European mitochondrial haplogroups and DR status. Results: The percentage of diabetes patients with DR did not differ across the haplogroups (P = 0.32). The percentage of patients with nonproliferative DR (NPDR; P = 0.0084) and with PDR (P = 0.027) significantly differed across the haplogroups. In logistic regressions adjusting for sex, age, diabetes type, duration of diabetes, and hemoglobin A1c, neither haplogroup H nor haplogroup UK had a significant effect on DR compared with diabetic controls. Haplogroup UK was a significant risk factor (OR = 1.72 [1.13-2.59], P = 0.010) for NPDR compared with diabetic controls in the unadjusted analysis, but not in the adjusted analysis (OR = 1.29 [0.79-2.10], P = 0.20). Conclusions: Mitochondrial haplogroups H and UK were associated with severity, but not presence, of DR. These data argue that the effect of these haplogroups is related to ischemia and neovascularization, the defining features of PDR.

Validation of photoscreening technology in the general pediatrics office: a prospective study.

BACKGROUND: Photoscreening instruments have been widely validated in pediatric ophthalmology clinics and field studies; however, validation by general pediatricians is lacking. We performed the first prospective, multisite evaluation of a commercially available photoscreener in the medical home. METHODS: Eleven practices in Middle Tennessee recruited over 3,100 children between 12 months and 5 years to be screened at well-child examinations. Participants were those who received a "refer" result; controls received a "pass." Referred children received a comprehensive eye examination with cycloplegic retinoscopy. A subset of control children underwent eye examinations in an attempt to determine sensitivity and specificity. RESULTS: The overall referral rate was 10%. Amblyopia risk factors (ARFs) were confirmed in 47% of referred children, with positive predictive values (PPVs) of 77.8% for suspected hyperopia, 60% for myopia, 50% for anisometropia, and 44.8% for astigmatism by the 2013 guidelines of the American Association of Pediatric Ophthalmology and Strabismus Vision Screening Committee. Using the 2003 guidelines, the overall PPV was 60.3%; PPVs were determined for suspected hyperopia (77.8%), myopia (60%), anisometropia (67.6%), and astigmatism (61.2%). Of referred children who received follow-up, 18 (13.2%) had amblyopia. PPVs for children ≤36 months (n = 79) did not differ from those 37-72 months (n = 57). No child who passed screening and had a follow-up examination had any ARFs. CONCLUSIONS: Our results replicate those of previously published field studies and support recent United States Preventive Services Task Force and American Academy of Pediatrics position statements. They provide prospective evidence that photoscreening is an effective tool for children aged 12-72 months.

Curbside radiology consults: how does the time allotted for review, level of training, and subspecialization affect interpretation accuracy?

The interpretation accuracy of resident and attending radiologists was assessed based on time allotted for study review, level of training, and subspecialization. Twelve cases were presented in a time-constrained and a time-unconstrained fashion to eight residents and six attendings. Overall, timed and untimed diagnostic accuracy was similar for all groups tested. Attendings sometimes performed worse than residents and in-field attendings when reviewing out-of-field studies. Residents often had greater specialty-specific accuracy than out-of-field attendings. Residents are capable of providing accurate "curbside" consultations to referring clinicians even under time-constrained conditions. Highly subspecialized attending radiologists should be cognizant of their out-of-field limitations.

Neurologic Functional and Quality of Life Outcomes after TBI: Clinic Attendees versus Non-Attendees.

This investigation describes the relationship between TBI patient demographics, quality of life outcome, and functional status outcome among clinic attendees and non-attendees. Of adult TBI survivors with intracranial hemorrhage, 63 attended our TBI clinic and 167 did not attend. All were telephone surveyed using the Extended-Glasgow Outcome Scale (GOSE), the Quality of Life after Brain Injury (QOLIBRI) scale, and a post-discharge therapy questionnaire. To determine risk factors for GOSE and QOLIBRI outcomes, we created multivariable regression models employing covariates of age, injury characteristics, clinic attendance, insurance status, post-discharge rehabilitation, and time from injury. Compared with those with severe TBI, higher GOSE scores were identified in individuals with both mild (odds ratio [OR]=2.0; 95% confidence interval [CI]: 1.1-3.6) and moderate (OR=4.7; 95% CI: 1.6-14.1) TBIs. In addition, survivors with private insurance had higher GOSE scores, compared with those with public insurance (OR=2.0; 95% CI: 1.1-3.6), workers' compensation (OR=8.4; 95% CI: 2.6-26.9), and no insurance (OR=3.1; 95% CI: 1.6-6.2). Compared with those with severe TBI, QOLIBRI scores were 11.7 points (95% CI: 3.7-19.7) higher in survivors with mild TBI and 17.3 points (95% CI: 3.2-31.5) higher in survivors with moderate TBI. In addition, survivors who received post-discharge rehabilitation had higher QOLIBRI scores by 11.4 points (95% CI: 3.7-19.1) than those who did not. Survivors with private insurance had QOLIBRI scores that were 25.5 points higher (95% CI: 11.3-39.7) than those with workers' compensation and 16.8 points higher (95% CI: 7.4-26.2) than those without insurance. Because neurologic injury severity, insurance status, and receipt of rehabilitation or therapy are independent risk factors for functional and quality of life outcomes, future directions will include improving earlier access to post-TBI rehabilitation, social work services, affordable insurance, and community resources.

Epithelioid hemangioma occurring in the radial styloid of a 17-year-old boy-an unusual presentation of an uncommon neoplasm.

Presented is a case of epithelioid hemangioma (EH) of bone occurring in the radial styloid of a 17-year-old boy. EH is a benign vascular tumor whose name and classification have changed over the years, adding potential confusion to an already existing diagnostic challenge. Overlapping imaging and histopathologic features with malignant vascular neoplasms and occasional aggressive clinical features have resulted in misdiagnoses and inappropriate treatment. The goal of this case report is to raise awareness of EH and related vascular neoplasms.
