Penetrating colored pencil injury with Clostridium bifermentans pre-septal cellulitis: case report, literature review, and treatment algorithm.

The incidence of penetrating orbital injuries from writing instruments continues to rise in the pediatric population. Such injuries can cause significant visual morbidity and have a lifelong psychosocial impact. While the description of graphite pencil-related orbital trauma management is well demonstrated with over 40 reported cases, a lack of consistent management protocol for colored pencil-related injuries. Here, we report an inadvertent penetrating orbital colored pencil injury with progressive mechanical ptosis and pre-septal cellulitis necessitating urgent orbitotomy, debridement, and washout to reduce inflammatory and infectious burden. The wooden body serves as a nidus for polymicrobial infection, and the unique composition of colored pencil cores may lead to inflammatory processes that require vigilant multidisciplinary surgical and medical management reflected in our literature review.

Structural Limits of Orbital Compliance and Treatment Options for Pathologic Orbital Pressure.

PURPOSE: The integrity of the orbit has a finite structural limit due to the compliance of its tissue. The authors investigate these limits to quantify them and inform the treatment of heightened ocular and orbital pressure. METHODS: Cadaveric study with 12 orbits being volumized before randomization of treatment for pathologic levels of ocular and orbital pressure. First-line and second-line treatment was chosen randomly (lateral cantholysis, superior septolysis, inferior septolysis). Prior to treatment, IOP, orbital compartment pressure, and axial globe projection was measured after delivery of each 1cc aliquot and surgical treatment. RESULTS: Orbital compartment pressure and IOP were well correlated (r = 0.99). The average reduction in IOP after treatment averaged a 56.2 mm Hg reduction in IOP. All treatments were statistically equivalent ( p < 0.01). Loss of compliance (P LOC ) was determined when the mean plus 1 standard deviation of change in IOP/ml volume was achieved with simultaneous change in exophthalmometry of <0.5 mm change/ml added volume, indicating an acceleration in pressure in the face of a steady volume. This criteria was met for 11 of 12 orbits. The 12th orbit missed this threshold by 1 mm Hg in IOP. P LOC occurred at an average IOP of 43.0 mm Hg (±5.8 mm Hg, 90% CI) and after an average injection of 13 ml (±1.4 mm, 90% CI). Additionally, lateral cantholysis, superior septolysis, and inferior septolysis were statistically equivalent in reducing IOP after P LOC . CONCLUSIONS: IOP and orbital compartment pressure are excellent proxies for each other in the authors' model. Orbital compliance is a mathematic phenomenon that can be quantified, as evident in this investigation. P LOC can inform timing for orbital decompressions in the presence of heightened IOP. Multiple procedures can be used to extinguish dangerously high orbital compartment pressure.

Efficacy and Safety of Teprotumumab in Patients With Thyroid Eye Disease of Long Duration and Low Disease Activity.

CONTEXT: Early inflammatory thyroid eye disease (TED) can lead to symptomatic chronic disease, including disabling proptosis. Teprotumumab, an insulin-like growth factor-1 receptor (IGF-1R) inhibitor, previously demonstrated efficacy in acute, high-inflammation TED trials. OBJECTIVE: We present data from the first placebo-controlled trial with teprotumumab in chronic/low disease activity TED. METHODS: This randomized double-masked, placebo-controlled trial, conducted at 11 US centers, enrolled adult participants with TED duration of 2 to 10 years, Clinical Activity Score (CAS) ≤ 1 or no additional inflammation or progression in proptosis/diplopia for ≥1 year, proptosis ≥3 mm from before TED and/or from normal, euthyroid/mildly hypo/hyperthyroid, no prior teprotumumab, and no steroids within 3 weeks of baseline. Patients received (2:1) intravenous teprotumumab or placebo once every 3 weeks (total 8 infusions). The primary endpoint was proptosis (mm) improvement at Week 24. Adverse events (AEs) were assessed. RESULTS: A total of 62 (42 teprotumumab and 20 placebo) patients were randomized. At Week 24, least squares mean (SE) proptosis improvement was greater with teprotumumab (-2.41 [0.228]) than with placebo (-0.92 [0.323]), difference -1.48 (95% CI -2.28, -0.69; P = .0004). Proportions of patients with AEs were similar between groups. Hyperglycemia was reported in 6 (15%) vs 2 (10%) and hearing impairment in 9 (22%) vs 2 (10%) with teprotumumab and placebo, respectively. AEs led to discontinuation in 1 teprotumumab (left ear conductive hearing loss with congenital anomaly) and 1 placebo patient (infusion-related). There were no deaths. CONCLUSION: Teprotumumab significantly improved proptosis vs placebo in longstanding/low inflammation TED, demonstrating efficacy regardless of disease duration/activity. The safety profile was comparable to that previously reported.

Patient-Reported Outcomes Following Medial Patellofemoral Reconstruction With Peroneus Longus Allografts Demonstrate Good Results.

Purpose: To evaluate the recurrent dislocation risk and patient-reported outcomes of peroneus longus allograft tissue for medial patellofemoral ligament (MPFL) reconstruction. Methods: Patients who underwent MPFL reconstruction with peroneus longus allograft at an academic center between 2008 and 2016 were identified. Record review and patient contact were used to identify any cases of recurrent patellar dislocation and collect patient-reported outcomes scores (Knee injury and Osteoarthritis Outcome Score [KOOS], Norwich Patellar Instability score, Marx activity scale). Patients with 1-year minimum follow-up were included. Outcomes were quantified and the proportion of patients reaching a previously defined patient acceptable symptom state (PASS) for patellar instability was determined. Results: Sixty-one patients (42 female and 19 male) underwent MPFL reconstruction with peroneus longus allograft during the study period. Forty-six patients (76%) with 1-year minimum follow up were contacted at a mean of 3.5 years postoperative. The mean age at time of surgery was 22 ± 7.2 years. Patient-reported outcomes data were available in 34 patients. Mean KOOS subscale scores were as follows: Symptoms 83.2 ± 19.1, Pain 85.2 ± 17.6, Activities of Daily Living 89.9 ± 14.8, Sports 75 ± 26.2, and Quality of Life 72.6 ± 25.7. The mean Norwich Patellar Instability score was 14.9% ± 17.4%. The mean Marx activity score was 6.0 ± 5.2. No recurrent dislocations were noted during the study period. Sixty-three percent of patients who underwent isolated MPFL reconstruction met PASS thresholds in at least 4 of 5 KOOS subscales. Conclusions: The use of a peroneus longus allograft in MPFL reconstruction in conjunction with other indicated procedures results in a low re-dislocation risk and a high proportion of patients meeting PASS criteria for patient-reported outcome scores 3 to 4 years postoperatively. Level of Evidence: IV, case series.

When the Cost of Vaping Is an Eye: A Case of an Open Globe and Superior Orbital Roof Fracture.

The authors report a penetrating orbitocerebral vape pen injury necessitating a primary enucleation and craniotomy to remove the foreign body fragments. A 31-year-old male presented with acute right vision loss after a modifiable vape pen explosion launched multiple projectile fragments into his right eye. CT revealed a deformed globe with multiple radiodense curvilinear fragments in the superior orbital roof and intracranial space. A right frontal craniotomy and orbitotomy with removal of vape pen fragments, reconstruction of the orbital roof, primary enucleation, and eyelid repair were performed in conjunction with neurosurgery. To the best of the authors' knowledge, this is the first reported penetrating globe injury from a vape pen explosion.

An Orbital Mystery: A Unique Case of an Obsolete Orbital Implant With a Review of Orbital Implant Materials.

Orbital implant materials have evolved greatly over the past century and include but are not limited to metal, ceramic, polymer, silicone, and glass. Knowledge of historically used materials is clinically relevant to patient care as certain materials carry a greater risk of migration, extrusion, infection, and limitations for imaging modalities utilized to visualize adjacent structures. We report an unusual case of an 80-year-old male who presented to our community hospital with seizure-like activity. CT imaging of the brain revealed several white matter and cortex lesions with the largest lesion measuring 2.5 × 2 × 1.9 cm. The patient had a history of enucleation with placement of an orbital implant following a penetrating injury to the left eye at four years of age. Hounsfield scale analysis was read by radiology as being most consistent with a thin metallic shell surrounding the orbital implant. The potential for metallic material was consistent with the implant's age and time of placement. Few reviews on ocular implant materials from this period exist in the current medical literature. A single case report discussing a hollow metal orbital implant with similar-appearing imaging was identified. Due to concern for possible metal implant materials, the patient underwent implant exchange so MRI imaging could safely be performed. Intraoperatively, the implant was identified as a clear, hollow, non-metallic, non-porous polymer sphere. Following surgery, the patient was able to undergo appropriate neuroimaging with subsequent diagnostic biopsy. Current literature reviewing CT or photographic imaging of ocular implant devices prior to the 1940s is limited. This case highlights the importance of detailing materials historically used in orbital implants, their effects on clinical decision-making, and the utility of Hounsfield scale values to identify a material's radiodensity on CT imaging.

Microfluidic live tracking and transcriptomics of cancer-immune cell doublets link intercellular proximity and gene regulation.

Cell-cell communication and physical interactions play a vital role in cancer initiation, homeostasis, progression, and immune response. Here, we report a system that combines live capture of different cell types, co-incubation, time-lapse imaging, and gene expression profiling of doublets using a microfluidic integrated fluidic circuit that enables measurement of physical distances between cells and the associated transcriptional profiles due to cell-cell interactions. We track the temporal variations in natural killer-triple-negative breast cancer cell distances and compare them with terminal cellular transcriptome profiles. The results show the time-bound activities of regulatory modules and allude to the existence of transcriptional memory. Our experimental and bioinformatic approaches serve as a proof of concept for interrogating live-cell interactions at doublet resolution. Together, our findings highlight the use of our approach across different cancers and cell types.

Influence of Patellofemoral Anatomy on Outcomes of Isolated Medial Patellofemoral Ligament Reconstruction for Recurrent Patellar Instability.

Background: Patella alta and elevated tibial tubercle-trochlear groove (TT-TG) distance can predispose patients to lateral patellar dislocations and recurrent instability. Their influence on patient-reported outcomes (PROs) after medial patellofemoral ligament (MPFL) reconstruction is less clear. Hypothesis: We hypothesized that neither moderately increased TT-TG distance nor patella alta would negatively affect PROs after isolated MPFL reconstruction in patients with relatively normal patellar tracking (no large J-sign). Study Design: Cohort study; Level of evidence, 3. Methods: We identified patients who underwent isolated MPFL reconstruction at a single institution between 2008 and 2016. The decision to perform an isolated MPFL reconstruction was at the discretion of the operating surgeon but was not performed in the setting of a large J-sign. Patient characteristics and surgical details were collected, and patients completed the Norwich Patellar Instability Score, Knee injury and Osteoarthritis Outcome Score, and Marx activity score. Patellar height (Caton-Deschamps Index [CDI]) was assessed on preoperative lateral radiographs, and TT-TG distance was measured on preoperative axial magnetic resonance imaging (MRI) scans. Patients were grouped based on CDI and TT-TG distance, and outcomes were compared. Linear regression modeling was performed to determine whether patella alta or elevated TT-TG distance was associated with poorer PRO scores. Results: Of 165 knees in 152 patients who underwent isolated MPFL reconstruction, 115 patients (125 knees; 76%) with minimum 1-year follow-up were contacted at a mean of 5.2 years after surgery. Recurrent dislocation occurred in 5 of 125 knees (4%). Preoperative radiographs were available in 111 knees (89%), and preoperative MRI scans were available in 89 knees (71%). Mean CDI was 1.13, and 35% had a CDI ≥1.20. Mean TT-TG distance was 17.5 mm, and 26% had a TT-TG distance >20 mm. After adjusting for patient age, sex, body mass index, and graft choice, we observed that neither patella alta nor elevated TT-TG distance were associated with poorer PROs. Conclusion: Isolated MPFL reconstruction in the setting of moderately elevated TT-TG distance or patella alta was not associated with worse PROs in this cohort with relatively normal patellar tracking (no large J-sign).

Head and neck arteriovenous malformations: University of Tennessee experience, 2012-2022.

OBJECTIVE: Head and neck arteriovenous malformations (AVMs) are complex lesions that represent a subset of vascular anomalies (VAs). The authors present an analysis of their institutional experience managing these lesions as a multidisciplinary team. METHODS: A retrospective chart review was performed of head and neck AVM patients treated at the authors' institution from 2012 to 2022. Recorded data included patient demographic characteristics, details of clinical presentation, Schöbinger clinical scale and Yakes AVM classification results, and details of all endovascular and surgical treatments. The primary outcome of the study was clinical response to treatment. Angiographic occlusion and complication rates were reported. Chi-square tests were used for comparative statistics. RESULTS: Sixteen patients (9 female, 56%) with AVMs of the head and neck presented from age 3 to 77 years. The Schöbinger stage was stage II in 56% of patients (n = 9) and stage III in 44% of patients (n = 7). The Yakes AVM classification was nidus type (2a, 2b, or 4) in 7 patients (43%) and fistula type (1, 3a, or 3b) in 9 patients (57%). The majority of patients (n = 11, 69.0%) were managed with embolization as the only treatment modality, with an average of 1.5 embolizations/patient (range 1-3). Surgical resection was employed in 5 patients (4 in combination with embolization). Symptom resolution and symptom control were achieved in 69% and 31% of patients, respectively, in the entire cohort. A radiographic cure was demonstrated in 50% of patients. There were no statistical differences in clinical outcomes or radiographic cure rates between patients treated with different modalities. CONCLUSIONS: Head and neck AVMs can be treated successfully with a primarily endovascular management strategy by a multidisciplinary team with the goal of symptomatic control.

Pediatric Orbital Roof Fractures: A Ratio of Orbital Dimensions Correlated to Prevalence of Fracture.

Objective Orbital roof fractures are more likely to occur in younger children, specifically younger than 7 years. Cranium to face ratio decreases with age; however, there is no definition for measurement of the neurocranium or face. We propose using the length of the orbital roof as a measurement of the neurocranium and length of the orbital floor as a tool to estimate midface size. The purpose of this study is to test this measurement as a correlation rate of orbital roof fractures within the pediatric population. Design This is a retrospective study. Setting This study was done at the LeBonheur Children's Hospital. Participants Sixty-six patients with orbital roof fractures were identified and stratified by gender and age, specifically younger than 7 years and 7 years or older. Main Outcome Measures The main outcome measures were orbital roof length, floor length, and ratio thereof. Results Mean orbital roof length was 43.4 ± 3.06 and 45.1 ± 3.94 mm for patients <7 and ≥7 years, respectively ( p = 0.02). Mean orbital floor length was 41.3 ± 2.99 and 47.7 ± 4.19 for patients <7 and ≥7 years, respectively ( p < 0.00001). The mean roof to floor ratio (RTFR) for patients <7 years was 1.051 ± 0.039 and for patients ≥ 7 years was 0.947 ± 0.031 ( p < 0.00001). Conclusion As children age, the relative length of the orbital roof decreases when compared with the orbital floor. The RTFR was more than 1.0 in children younger than 7 years. These differences were statistically significant when compared with children 7 years and older. This measurement shift follows the differences noted in orbital fracture patterns during childhood.

The role of ERNDIM diagnostic proficiency schemes in improving the quality of diagnostic testing for inherited metabolic diseases.

External quality assurance (EQA) is crucial to monitor and improve the quality of biochemical genetic testing. ERNDIM (www.erndim.org), established in 1994, aims at reliable and standardized procedures for diagnosis, treatment and monitoring of inherited metabolic disease (IMD) by providing EQA schemes and educational activities. Currently, ERNDIM provides 16 different EQA schemes including quantitative schemes for various metabolite groups, and interpretive schemes such as diagnostic proficiency testing (DPT). DPT schemes focus on the ability of laboratories to correctly identify and interpret abnormalities in authentic urine samples across a wide range of IMDs. In the DPT schemes, six samples each year are distributed together with clinical information. Laboratories choose and perform the tests needed to reach a diagnosis. Data were collected on 345 samples, distributed to up to 105 laboratories worldwide. Diagnostic proficiency (the % of total points possible for all participating laboratories within a scheme for analysis and interpretation) ranged widely: amino acid disorders (n = 20), range 33%-100%, mean 84%; organic acid disorders (n = 35), range 14%-100%, mean 84%; lysosomal storage disorders (n = 13), range 20%-97%, mean 73%; purine/pyrimidine disorders (n = 9), range 37%-100%, mean 70%; miscellaneous disorders (n = 8), range 17%-100%, mean 65%; no IMD, range 65%-95%, mean 85%. When a sample with the same disorder was distributed in a subsequent survey, performance improved in 75 cases with no improvement seen in 32, suggesting overall improvement of performance. ERNDIM diagnostic proficiency testing is a valuable activity which can help to assess laboratory performance, identify methodological/technical challenges, be informative during quality audits and contribute to a better clinical appreciation of diagnostic uncertainty.

Spontaneous orbital hemorrhage in a case of acute liver failure.

Purpose: To report an unusual case of spontaneous orbital hemorrhage in the setting of DIC and hepatic failure. Observations: A 33-year-old female presented to the Emergency Department (ED) with acute liver failure. During the first week of her hospital admission, she developed unilateral eyelid swelling and proptosis, prompting a consult to ophthalmology. Additional physical examination revealed significantly decreased visual acuity, extraocular muscle restriction, afferent pupillary defect, and increased intraocular pressure. Computed tomography (CT) and ultrasound confirmed the diagnosis of intraorbital hemorrhage. Aggressive management in the form of lateral canthotomy, cantholysis, and septolysis was unable to be performed due to the patient's multiple comorbidities outweighing the potential benefits. Conclusions and importance: This rare phenomenon is unique from previous existing literature in that the timing of the incident limited the therapeutic options for this patient, additional imaging in the form of ultrasound was utilized in the work-up, and to our knowledge this is the second case of spontaneous orbital hemorrhage as a complication of disseminated intravascular coagulation (DIC) caused by hepatic failure.

Teprotumumab Efficacy, Safety, and Durability in Longer-Duration Thyroid Eye Disease and Re-treatment: OPTIC-X Study.

PURPOSE: To evaluate teprotumumab safety/efficacy in patients with thyroid eye disease (TED) who were nonresponsive or who experienced a disease flare. DESIGN: The Treatment of Graves' Orbitopathy to Reduce Proptosis with Teprotumumab Infusions in an Open-Label Clinical Extension Study (OPTIC-X) is a teprotumumab treatment and re-treatment trial following the placebo-controlled teprotumumab Phase 3 Treatment of Graves' Orbitopathy (Thyroid Eye Disease) to Reduce Proptosis with Teprotumumab Infusions in a Randomized, Placebo-Controlled, Clinical Study (OPTIC) trial. PARTICIPANTS: Patients who previously received placebo (n = 37) or teprotumumab (n = 14) in OPTIC. METHODS: OPTIC nonresponders or those who flared (≥2-mm increase in proptosis, ≥2-point increase in clinical activity score [CAS], or both) during follow-up were treated for the first time (previous placebo patients) or re-treated with teprotumumab in OPTIC-X with 8 infusions over 24 weeks. MAIN OUTCOME MEASURES: Proptosis response and safety. Secondary outcomes included proptosis, CAS, subjective diplopia, and quality-of-life. RESULTS: Thirty-three of 37 placebo-treated OPTIC patients (89.2%) became proptosis responders (mean ± standard deviation, -3.5 ± 1.7 mm) when treated with teprotumumab in OPTIC-X. The responses were equivalent to the OPTIC study. In these responders, proptosis, CAS of 0 or 1, and diplopia responses were maintained in 29 of 32 patients (90.6%), 20 of 21 patients (95.2%), and 12 of 14 patients (85.7%), respectively, at follow-up week 48. The median TED duration was 12.9 months versus 6.3 months in those treated with teprotumumab in the OPTIC study. Of the 5 OPTIC teprotumumab nonresponders re-treated in OPTIC-X, 2 responded, 1 showed a proptosis reduction of 1.5 mm from OPTIC baseline, and 2 discontinued treatment early. Of the OPTIC teprotumumab responders who experienced flare, 5 of 8 patients (62.5%) responded when re-treated (mean proptosis reduction, 1.9 ± 1.2 mm from OPTIC-X baseline and 3.3 ± 0.7 mm from OPTIC baseline). Compared with published double-masked trials and their integrated follow-up, no new safety signals were identified. Mild hearing impairment was reported; 4 events occurred during the first course of treatment, and 2 events reoccurred after re-treatment. CONCLUSIONS: Patients with TED of longer disease duration responded similarly to those treated earlier in the disease course. Patients with an insufficient initial response or flare may benefit from additional teprotumumab therapy. No new safety risk was identified; however additional postmarketing pharmacovigilance is ongoing.

Long-acting opioid prescribing patterns of ophthalmic plastic surgeons in the medicare Part D database.

PURPOSE: To assess extended release/long acting (ER/LA) opioid prescribing patterns among ophthalmic plastic surgeons in the Centers for Medicare and Medicaid Services (CMS) Part D database. METHODS: A retrospective observational cohort study was conducted on oculoplastic surgeons in the CMS Part D database who prescribed ER/LA opioids from 2013 to 2017. American Society of Ophthalmic Plastics and Reconstructive Surgery (ASOPRS) and non-ASOPRS surgeons were analyzed as groups. Prescribers were also analyzed based on gender and practice experience. RESULTS: Oculoplastic surgeons (64 ASOPRS and 78 non-ASOPRS) were responsible for 1,177 ER/LA opioid prescriptions from 2013 to 2017. ASOPRS members accounted for 4.6% and non-ASOPRS members accounted for 7.5% of all ER/LA opioids prescribed by ophthalmologists over the study period (p= .02). The total number of ASOPRS and non-ASOPRS members prescribing ER/LA opioids decreased by 52% (p= .10) and 58% (p= .07) from 2013 to 2017 respectively. CONCLUSION: ER/LA opioids are indicated for treatment of chronic pain and may be appropriately prescribed by the oculoplastic surgeon in certain circumstances, however due to the higher risk of overdose injury, those circumstances must be defined and justified. While a relatively small number of oculoplastic surgeons (10.6% ASOPRS and 19.6% non-ASOPRS) prescribed ER/LA opioids from 2013 to 2017, non-ASOPRS oculoplastic surgeons wrote 23.5% more ER/LA opioid prescriptions over the study period. Over the 5-year study period there was a general decline in the prescribing of ER/LA opioids by oculoplastic surgeons. Reviewing the prescribing practices of oculoplastic specialists, regardless of professional affiliation, is necessary to understand the role of ER/LA opioids for all of ophthalmology.

Effect of Premature Tube Extrusion for Simple Congenital Nasolacrimal Duct Obstruction: A Comparison of Monocanalicular and Bicanalicular Intubation.

ABSTRACT: The objective of this article is to compare the incidence of premature dislocation of silicone tubes and the effect on treatment success between monocanalicular (MCI) and bicanalicular (BCI) intubation in pediatric patients with simple congenital nasolacrimal duct obstruction. Retrospective comparative case series of 108 eyes of 78 pediatric patients with simple congenital nasolacrimal duct obstruction who underwent probing with either BCI (n = 38 eyes) or MCI (n = 70 eyes) from 2017 to 2020. Premature tube extrusion was defined as any tube removed prior to the 3 month postoperative appointment. Success was defined as resolution of tearing 3 months post tube removal. Ages ranged from 10 months to 5.35 years (mean, 1.95 years; Standard deviation (SD), 0.91). Premature tube extrusion occurred in 15 eyes with BCI and 29 eyes with MCI. Success rates were not significantly different regardless of intubation type between the planned tube removal (90.6%) and the premature tube extrusion cohorts (84.1%), P = 0.89. There was no significant difference in treatment success between the planned tube removal (92.7% MCI, 87% BCI) and the premature tube extrusion cohorts (86.2% MCI, 80% BCI). Complications included 2 infections (1 MCI, 1 BCI) and 2 cases of tube related keratopathy (1 MCI, 1 BCI) that all resolved with tube removal. There were 2 BCI patients that presented to the emergency department for premature tube extrusion. Silicone intubation regardless of stent type is an effective treatment for simple congenital nasolacrimal duct obstruction. There was no significant difference in treatment success between tubes that extrude prematurely, and tubes removed at term based on type of intubation.

Opioid Prescribing Patterns of Optometrists in the Medicare Part D Database.

SIGNIFICANCE: This study aimed to determine the prescription rates and prescribing trends of opioids by optometrists in the Centers for Medicare & Medicaid Services (CMS) part D database from 2013 to 2017 and to assess opioid prescribing patterns of U.S. optometrists in the CMS part D database. METHODS: With internal review board approval, a retrospective observational cohort study was conducted on optometrists listed in the CMS part D database who prescribed opioids from 2013 to 2017. RESULTS: There was an average of 26,477 optometrists in the CMS database from 2013 to 2017, of which 5.9% prescribed opioids. Of those prescribing opioids, optometrists wrote an average of 5.9 opioid prescriptions per year. Those writing greater than 10 opioid prescriptions averaged 24.2 annually. Overall, of opioid prescribing optometrists, opioid prescriptions comprised 7% of prescriptions written per year. CONCLUSIONS: Most optometrists do not prescribe opioids, and the vast majority of those who do write few opioid prescriptions. The total number of optometrists prescribing opioids and the total number of opioid prescriptions declined from 2013 to 2017. Further investigation into the opioid prescribing practices by optometrists will help better understand specific pain needs, as opioid prescribing patterns may differ depending on patient population.

Acute cardiotoxicity after initiation of the novel tyrosine kinase inhibitor gilteritinib for acute myeloid leukemia.

BACKGROUND: Gilteritinib is a novel FMS-like tyrosine kinase 3 inhibitor recently approved by the United States Food and Drug Administration in 2018 for relapsed or refractory acute myeloid leukemia. However, gilteritinib may be associated with underrecognized cardiotoxicities. CASE PRESENTATION: This case describes a patient with a history significant for hyperlipidemia who was diagnosed with relapsed acute myeloid leukemia. After four doses of gilteritinib monotherapy, she abruptly developed acute systolic heart failure with global hypokinesis and septal wall motion abnormalities. Two days after discontinuation, cardiac magnetic resonance imaging showed partial recovery of her left ventricular ejection fraction as well as myocardial edema and non-ischemic fibrosis suggestive of inflammatory cardiomyopathy. She underwent intravenous diuresis and eventually started guideline-directed heart failure therapy. Follow-up cardiac magnetic resonance imaging five months later showed improved ejection fraction with mild non-ischemic fibrosis and resolution of myocardial edema and inflammation. She later received an allogeneic stem cell transplant from a matched unrelated donor. CONCLUSIONS: Gilteritinib may be associated with early cardiotoxicities, including non-ischemic cardiomyopathy and myocarditis. Cardiac magnetic resonance imaging can be an important modality to help differentiate or diagnose early cardiotoxicities associated with novel targeted therapies.

Total or subtotal replacement of tarsal plate by novel silicone plate for upper eyelid reconstruction in malignant tumors.

PURPOSE: : To evaluate the cost, safety, surgical outcome, and efficacy of modified Cutler-Beard eyelid reconstruction utilizing a novel silicone plate as a tarsal plate replacement in the repair of 60% to 100% eyelid defects following the excision of large malignant tumors. METHODS: : A prospective, noncomparative, interventional study of 30 eyes was done over 3 years. Fourteen patients were female, and 16 patients were male. In all the cases, a silicone plate, the synthetic, artificial tarsal plate, was utilized for a total or subtotal replacement of the tarsal plate. The created defect was measured in mm (length and width) and later expressed in percentage. Pre- and postoperative action of levator palpebrae superioris (LPS) was measured. Pre- and postoperative measurements of the margin-to-margin reflex distance (MRD1) were noted. RESULTS: : Preoperative LPS action was 1.23 ± 1.35 mm, whereas postoperative LPS actions at the end of 1 week and 18 months were 11. 8 ± 0.88 mm and 13.53 ± 0. 73 mm, respectively. Preoperative MRD1 was - 3.0 ± 1.144 mm, whereas postoperative MRD1 values at the end of 1 week and 18 months were 2.18 ± 0.27 mm and 4.16 mm ± 0.35, respectively. The mean created defect after the removal of the tumor was 87.3% ±11.10. The mean length of the silicone plate implanted in this study was 27.53 ± 2.48 mm. The follow-up period for the study participants was 18 months. CONCLUSION: : The synthetic novel silicone plate was successful as a tarsal plate replacement. A second surgical site for ear cartilage harvesting is avoided. Cadaver transfer of Achilles tendon carries the risk of transmission of communicable diseases, for example, hepatitis B and HIV. Silicone is an inert, nonreacting, and tissue-tested material, thus eliminating the possibility of graft rejection. This material is readily available and cost-effective. The novel silicone plate is considered to be the most promising alternative material as a tarsal replacement in the future generation.

Management of Eye Trauma for the Primary Care Physician.

Eye trauma is frequently seen by non-ophthalmology providers. This article elucidates a methodological approach to eye trauma. The first step is to address any life-threatening conditions. Then a focused history and exam is discussed, starting externally. Then, key history, physical, pathophysiology, and basic management of common, serious eye injuries are discussed: chemical injury, orbital fractures, open globe, traumatic hyphema, retinal detachment, traumatic optic neuropathy, and eyelid laceration. Finally, we highlight the practicality of telemedicine for areas where ophthalmology coverage is lacking.

EVALI versus MIS-C, one more overlapping diagnosis to consider.

We describe six teenagers presenting with fever and severe abdominal symptoms admitted with concerns for multisystem inflammatory syndrome in children (MIS-C). Laboratory evaluation revealed elevated markers of inflammation, lymphopenia, and increased D-dimers. Imaging studies revealed multifocal airspace disease and ground-glass opacities. SARS-CoV-2 polymerase chain reaction and serologies were negative. All patients reported a history of vaping, prompting E-cigarette, or vaping, product use-associated lung injury (EVALI) diagnosis. MIS-C has overlapping clinical and laboratory features highlighting the added challenge of diagnosing EVALI during the COVID-19 pandemic. Keywords COVID-19 pandemic, EVALI, MIS-C.
