THE USE OF NON-PERSON-FIRST LANGUAGE IN CONSECUTIVE GENERAL OPHTHALMOLOGY REFERRALS.

PURPOSE: To investigate the prevalence of non-person-first language (PFL) in consecutive general ophthalmology referrals to a single tertiary ophthalmology clinic. DESIGN: Retrospective cross-sectional study. METHODS: Participants included Ophthalmology patients seen for their initial visit to a single tertiary ophthalmology clinic from July 2018 to December 2022. Ten randomly selected referrals from each day were screened for non-PFL as per the American Medical Association and American Psychological Association guidelines. Non-PFL was further categorized into general, diabetes, stigma, obesity, or ageism subcategories. The Chi-square test was used to evaluate associations between non-PFL use and referring provider gender and specialty, length of referral, and patient age and gender. RESULTS: A total of 2625 referrals were included in the study and 136 (5.2%) used non-PFL, such as referring to a person with diabetes as a "diabetic". Error types included Diabetes (38.2%), Stigma (30.9%), General (23.5%), Disability (8.8%), and Obesity (4.4%). Year of referral was predictive of non-PFL (p=0.0016), with most occurring in 2020 (9.5%). Non-PFL was significantly more likely to occur in long length referrals compared to medium and short length referrals (16.2% vs. 5.1% vs. 3.5%, p<0.001). Referring provider specialty was also predictive of non-PFL (p<0.001) with most received by Family Medicine (8.3%), Optometry (4.4%), Emergency Medicine (0.62%), Ophthalmology (4.2%), Others (2.9%). Patient gender (p=0.5563), patient age (p=0.3466), and referring provider gender (p=0.9057) were not predictive of non-PFL. CONCLUSIONS: Non-PFL use was most prevalent in 2020, with the most common referral sources being Family Medicine and Optometry. The highest proportions of non-PFL errors made were diabetes and stigma errors. Increased use of PFL in physician-physician communication can decrease intersectional stigma and promote inclusive patient care for ophthalmology patients.

Correlation between Clinical Outcome and Radiologic Features After Open Reduction and Internal Fixation of Calcaneal Fractures.

BACKGROUND: We aimed to find probable correlation between postoperative radiologic variables and clinical outcomes of surgically treated calcaneal fractures. METHODS: In a retrospective study, 70 unilateral displaced intraarticular calcaneal fractures in adults with follow-up more than 1 year were asked to have a visit. Weightbearing radiographs of both ankles were taken and radiologic parameters, including the differences in values in Böhler and Gissane angles in comparison with the uninjured side, and calcaneocuboid and subtalar joint arthritis based on the Kellgren-Lawrence grading scale, were evaluated. They were considered to find any correlation with clinical outcomes assessed by American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scale, visual analogue scale, Foot Function Index, and Tegner Activity Scale. RESULTS: A total of 61 men (87.1%) and nine women (12.9%) with a mean age of 38.9 ± 12.7 years (range, 18-67 years) were included. Mean follow-up visit for the patients was 25.1 ± 12.7 months. Mean scores of American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scale, visual analogue scale, Foot Function Index, and Tegner Activity Scale were 86.7 ± 12.9, 21.3 ± 22.2, 13.1 ± 15.4, and 5.2 ± 1.1, respectively. The mean Gissane angle and Böhler angle differences were -0.2 ± 8.6 and -3.7 ± 7.2, respectively. Regarding the calcaneocuboid arthritis, 50 (71.4%), 14 (20.0%), and six patients (8.6%) were categorized in grades 0, 1, and 2, respectively. Also, subtalar arthritis was seen in 15 (21.4%), 24 (34.3%), 20 (28.6%), and 11 patients (15.7%), categorized as grades 0, 1, 2, and 3, respectively. No statistical correlation was found between any of the radiologic variables and clinical scores. CONCLUSIONS: There was no significant correlation between Böhler and Gissane angles and the clinical outcomes in surgically treated calcaneal fractures. Also, functional outcomes do not change considerably among different grades of arthritis in calcaneocuboid and subtalar joints, at least during short- to mid-term follow-up periods. Radiologic findings after open reduction and internal fixation of calcaneal fractures are not predictors of function of the patients.

Patterns of Ankle Fractures Based on Radiographs and CT Images of 1000 Consecutive Patients.

Objectives: The knowledge of different types of ankle fractures based on plain radiographs and computed tomography (CT) images can help improve patients' management. Methods: This cross-sectional study assessed the plain radiographs and CT images of 1,000 consecutive patients observed in an emergency department between March 2015 and March 2020. Fractures were labeled as uni-, bi-, or trimalleolar. Malleolar fractures were classified into medial, lateral, and posterior ones based on Herscovici, Danis-Weber, and Mason and Molloy classifications, respectively. Bi- and trimalleolar fractures, on the other hand, were categorized according to the Lauge-Hansen classification. Results: This study included 1,000 patients with 1,003 ankle fractures. Of them, 901 were adults (mean±SD age: 41.6±16.7, male: 567 [62.9%]) with 904 fractures. In total, 53% of adult patients were 18 to 39 years old. Considering unilateral ankle fractures, the medial malleolar fracture was the most common unimalleolar fracture (62.6%), with Herscovici C being the most frequent subtype (65.3%). On the other hand, the most common type of lateral malleolar fracture was Danis-Weber type B (65.5%). There were also 209 (23.3%) bimalleolar and 114 (12.7%) trimalleolar fractures, 5.8% (16 fractures) of which could not be classified based on the Lauge-Hansen classification. Unimalleolar fractures were also observed in 87 (87.9%) children, with the medial malleolar fracture being the most common type (89.7%). Conclusion: Medial malleolar fractures were the most frequent malleoli in patients observed in the emergency department under study. Among bi- and trimalleolar ankle fractures, supination-external rotation and pronation-external rotation injuries were the most common patterns. The Lauge-Hansen classification was not applicable in 5.8% of bi- and trimalleolar fractures.

Diversity in enrollment to clinical trials for cataract medicine and surgery: meta-analysis.

PURPOSE: To investigate sex, racial, and ethnic disparities in patient enrollment across cataract trials registered in the United States. SETTING: Participants enrolled in high-quality (reduced risk of bias), U.S.-registered (on ClinicalTrials.gov ), cataract-related randomized controlled trials (RCTs). RCTs must be completed, have used double or greater masking, and have published results through the registry or a scholarly journal. DESIGN: Cross-sectional database study. METHODS: Trial (study sponsor country, study site location, trial initiation year, study phase, and study masking) and demographic data (sex, race, and ethnicity according to U.S. reporting guidelines) were collected. The Global Burden of Disease database provided sex-based cataract disease burdens. Pooled participation-to-prevalence ratios (PPRs) with 95% CIs were calculated for female sex, with values between 0.8 and 1.2 constituting sufficient study enrollment. Kruskal-Wallis tests (α = 0.05) with subsequent post hoc comparisons were used to evaluate demographic representations stratified by trial characteristics. RESULTS: From 864 records, 100 clinical trials (N = 67 874) were identified, of which 97 (N = 67 697) reported sex demographics with a pooled female PPR of 0.89 (95% CI, 0.85-0.94). Of the 67 697 total participants, the absolute female enrollment was 19 062 (28.16%). Ethnicity and race were reported in 9 (N = 1792) and 26 trials (N = 23 181), respectively. Among trials that reported race, most were White (N = 19 574; 84.44%). CONCLUSIONS: High-quality, U.S.-registered, cataract trials enrolled acceptable proportions of women. However, the absolute number of female and racialized participants was low. Race and ethnicity were underreported. Disparity trends predominately held across secondary variables. To promote generalizability, future trials should pursue equitable demographic enrollment.

Utility of ChatGPT for Automated Creation of Patient Education Handouts: An Application in Neuro-Ophthalmology.

BACKGROUND: Patient education in ophthalmology poses a challenge for physicians because of time and resource limitations. ChatGPT (OpenAI, San Francisco) may assist with automating production of patient handouts on common neuro-ophthalmic diseases. METHODS: We queried ChatGPT-3.5 to generate 51 patient education handouts across 17 conditions. We devised the "Quality of Generated Language Outputs for Patients" (QGLOP) tool to assess handouts on the domains of accuracy/comprehensiveness, bias, currency, and tone, each scored out of 4 for a total of 16. A fellowship-trained neuro-ophthalmologist scored each passage. Handout readability was assessed using the Simple Measure of Gobbledygook (SMOG), which estimates years of education required to understand a text. RESULTS: The QGLOP scores for accuracy, bias, currency, and tone were found to be 2.43, 3, 3.43, and 3.02 respectively. The mean QGLOP score was 11.9 [95% CI 8.98, 14.8] out of 16 points, indicating a performance of 74.4% [95% CI 56.1%, 92.5%]. The mean SMOG across responses as 10.9 [95% CI 9.36, 12.4] years of education. CONCLUSIONS: The mean QGLOP score suggests that a fellowship-trained ophthalmologist may have at-least a moderate level of satisfaction with the write-up quality conferred by ChatGPT. This still requires a final review and editing before dissemination. Comparatively, the rarer 5% of responses collectively on either extreme would require very mild or extensive revision. Also, the mean SMOG score exceeded the accepted upper limits of grade 8 reading level for health-related patient handouts. In its current iteration, ChatGPT should be used as an efficiency tool to generate an initial draft for the neuro-ophthalmologist, who may then refine the accuracy and readability for a lay readership.

Prevalence of Person-First Language in Idiopathic Intracranial Hypertension: A Systematic Review of Case Reports.

BACKGROUND: Person-first language (PFL) is a linguistic prescription, which places a person before their disease. It is considered an important tool to reduce stigma. However, PFL is not routinely used across the scientific literature, particularly in patients with overweight or obesity. Patients with idiopathic intracranial hypertension (IIH) face various stigmas through high rates of poverty, female gender, and frequent rates of comorbidities. Non-PFL language use intersects and worsen the health inequities faced by these patients. METHODS: A systematic review of case reports. MEDLINE and EMBASE were searched for all case reports with "pseudotumor cerebri" [MESH] OR "Idiopathic Intracranial Hypertension" as key word between January 1974 and August 2022. The primary criterion was the article's inclusion of patients with overweight or obesity. The secondary criterion was the article's discussion regarding obesity as risk factor. Articles not meeting primary or secondary criteria were excluded. RESULTS: Approximately 514/716 (71.8%) articles used non-PFL language. The publication year was predictive of non-PFL language: 1976-1991 (82.3%) vs 1992-2007 (72.3%, P = 0.0394) and 2008-2022 (68.3%, P = 0.0056). Non-PFL was significantly higher in obesity compared with other medical conditions (60.3% vs 7.3%, P < 0.001). The patient gender (P = 0.111) and ethnicity (P = 0.697), author's specialty (P = 0.298), and primary English-speaking status (P = 0.231), as well as the journal's impact factor (P = 0.795), were not predictive of non-PFL. CONCLUSIONS: Most literature focused on IIH use non-PFL when discussing overweight or obesity, regardless of the patient's gender and ethnicity, journal's impact factor, senior author's specialty, and English-speaking status. Non-PFL use is much more common when discussing obesity compared with other medical conditions. Appropriate use of PFL can decrease stigma and, more importantly, decrease the intersectionality of health stigma faced by patients with IIH.

Prevalence and Predictors of Peroneal Tendon Instability Accompanying Calcaneal Fractures.

BACKGROUND: We aimed to find the prevalence of peroneal tendon instability (PTI) accompanying different types of calcaneal fractures and to determine predictors of PTI based on preoperative CT scanning. METHODS: In a retrospective cross-sectional study, preoperative CT scans of 400 consecutive calcaneal fractures undergoing surgery were reviewed for comminuted fragments in the lateral gutter of the ankle, fractures at the tip of the lateral malleolus, dislocated peroneal tendons, excessive displacement of the lateral calcaneal wall, calcaneal fracture-dislocation, superior peroneal retinaculum (SPR) avulsion fracture (fleck sign), and shape of the retromalleolar groove. The correlation of these variables with intraoperative SPR stress test, defined as the diagnostic criteria for PTI in calcaneal fractures, was evaluated. RESULTS: In total, 369 patients (mean age, 39 ± 13; range, 11-72 years), with 321 (87.0%) of them male, were included. Among all calcaneal fractures, 67 cases (16.7%) had associated PTI as confirmed intraoperatively by an SPR stress test. A statistically significant association was found between PTI in calcaneal fractures and comminuted fragments in the lateral gutter of the ankle (P = .03), dislocated peroneal tendons (P < .001), calcaneal fracture-dislocation (P < .001), SPR avulsion fracture (P < .001), and Sanders type IV of calcaneal fracture (P = .02). There was no statistically significant relationship between PTI and the mechanism of injury (P = .98), side of fracture (P = .30), uni- or bilateral calcaneal fractures (P = .27), a fracture at the tip of lateral malleolus (P = .69), shape of the retromalleolar groove (P = .78), or excessive displacement of the lateral calcaneal wall (P = .06). The most specific CT finding to predict PTI accompanying calcaneal fractures was calcaneal fracture-dislocation (99.1%). CONCLUSION: Following calcaneal fracture fixation, PTI was confirmed with intraoperative SPR stress test in one-sixth of cases. With the exception of calcaneal fracture-dislocation, preoperative findings on CT scanning and calcaneal fracture pathoanatomy are insufficient to diagnose PTI accompanying calcaneal fractures. LEVEL OF EVIDENCE: Level III, retrospective case control study.

Anemia and idiopathic intracranial hypertension: a prospective study.

BACKGROUND: Anemia has been temporally associated with idiopathic intracranial hypertension (IIH), but the relationship is uncertain because of a lack of prospective studies and because both IIH and anemia are common in young women with obesity. DESIGN AND METHODS: This was a prospective study of consecutive patients with IIH referred to 3 neuro-ophthalmology centres between March 2021 and September 2022. All patients had a complete blood count available within 6 months of presentation. Anemia was defined as mild (110-120 g/L), moderate (80-109 g/L), and severe (<80 g/L). RESULTS: Of 143 patients, 113 had normal hemoglobin (group 1) and 30 had anemia (group 2). In group 2, the anemia was defined as mild (15 of 30; 50.0%), moderate (11 of 30; 36.7%), and severe (4 of 30; 13.3%). There was no difference in female sex (105 of 113 vs 29 of 30; p = 0.453), age (31.5 ± 9.2 years vs 28.5 ± 10.3 years; p = 0.144), and body mass index (35.2 ± 6.9 kg/m2 vs 38.0 ± 8.1 kg/m2; p = 0.111). Groups 1 and 2 did not differ in visual acuity (0.04 ± 0.09 logMAR vs 0.07 ± 0.14 logMAR; p = 0.377), retinal nerve fibre layer thickness (174.5 ± 68.4 µm vs 206.5 ± 97.0 µm; p = 0.098), mean deviation (-3.2 ± 3.1 dB vs -3.9 ± 3.4 dB; p = 0.180), and the need for medical (34 of 113 vs 8 of 30; p = 0.715) or surgical treatment (3 of 113 vs 3 of 30; p = 0.074). Patients with moderate to severe anemia were more likely to require surgical therapy (2 of 15 vs 3 of 113; p = 0.045). CONCLUSION: Approximately 1 of every 5 patients with IIH has anemia, and this is severe in >10% of patients. Patients with moderate and severe anemia may require more invasive surgical treatment. Given the high incidence of anemia and the availability of a complete blood count, we recommend that this test be obtained for all patients with suspected IIH.

Preservation of Vision after Early Recognition of Anterior Ischemic Optic Neuropathy in a Patient with Sepsis.

Non-arteritic ischemic optic neuropathy (NAION) can rarely occur in the setting of sudden vascular compromise, especially in patients with a "disk-at-risk" appearance. Anemia and hypotension are believed to be the main precipitators of shock-induced NAION. Early recognition of this phenomenon can prevent further visual loss and result in partial visual recovery. We here present a 56-year-old patient who developed NAION characterized by optic disc edema in both eyes and visual loss in the left eye secondary to hypotension in the setting of septic shock. He received aggressive blood pressure management (stopping all his anti-hypertensives, hydration, and midrodrine) which resulted in stabilization of vision in the right eye and likely prevented further visual loss in the left eye.

Maculopathies Referred to Neuro-Ophthalmology Clinic as Optic Neuropathies: A Case Series.

BACKGROUND: The clinical features of maculopathies and optic neuropathies often overlap: Both present with decreased visual acuity and variable loss of color vision; thus, maculopathy can be misdiagnosed as optic neuropathy, leading to patient harm. We aimed to determine what findings and/or tests were most helpful in differentiating between optic neuropathy and maculopathy. METHODS: A retrospective chart review of consecutive patients over 4.5 years who were referred to neuro-ophthalmology clinics with the diagnosis of optic neuropathy but whose final diagnosis was maculopathy. Patient demographics, mode of presentation, clinical profile, complete ophthalmological examination, results of all ancillary testing, and final diagnosis were recorded. RESULTS: A total of 47 patients (27 women) were included. The median age was 55 years (range, 18-85). Most referrals were by ophthalmologists (72.3%) and optometrists (12.8%). The diagnosis of maculopathy was made in 51.1% of patients at the time of first neuro-ophthalmic consultation. Only 6.4% patients (3) had relative afferent pupillary defect. Benign disc anomalies (tilted, myopic, small, or anomalous discs) were present in 34.0%, and 21.3% had pathologic disc changes unrelated or secondary to maculopathy. Macular ocular coherence tomography (OCT) was abnormal in 84.4% (with outer retinal pathology in 42.2% and inner retina pathology in 17.8%). Retinal nerve fiber layer (RNFL) thickness was normal in 82.6% of patients. CONCLUSIONS: Macular OCT is a high-yield test in differentiating between optic neuropathy and maculopathy and should be obtained in patients with suspected optic neuropathies who have normal RNFL thickness. Macular dystrophies, particularly cone dystrophies, unspecified retinal disorders, and macular degeneration were the most common mimics of optic neuropathy. The diagnosis was often present on OCT of the macula. The presence of coexistent benign and pathological disc anomalies may lead to maculopathy being misdiagnosed as optic neuropathy.

Unilateral Pendular Nystagmus in Multiple Sclerosis: A Case Series.

BACKGROUND: Acquired pendular nystagmus is most often seen in patients with demyelinating disease. Although it is often bilateral, rare cases may be monocular. There is paucity of data on the spectrum of clinical presentation, underlying mechanism, and response to treatment in patients with monocular pendular nystagmus. METHODS: Retrospective case series of patients with monocular pendular nystagmus seen in 2 tertiary neuro-ophthalmology clinics between January 2019 and June 2022. All patients underwent a complete neuro-ophthalmological assessment and MRI. RESULTS: We describe 5 patients (3 women) aged 31-49 with monocular pendular nystagmus. All had a diagnosis of multiple sclerosis. Three patients had horizontal and 2 had vertical pendular nystagmus. The Snellen visual acuity in the eye with pendular nystagmus varied from 20/20 to 20/200. Two patients were asymptomatic and 3 suffered visually debilitating oscillopsia. Treatment response was available for 2 patients, both of which responded well to treatment with memantine. The pendular nystagmus was observed in the eye with worse visual acuity in 4 of 5 cases (80%). Three patients had bilateral pontine lesions, and 2 had unilateral pontine lesion ipsilateral to the side of nystagmus. CONCLUSIONS: Monocular pendular nystagmus in adults is seen most often in patients with multiple sclerosis. Asymmetry in brainstem lesions and afferent visual input may be the culprit. Treatment with memantine may result in significant improvement in symptomatic patients.

Inappropriate Indexing of Case Reports to the "Papilledema" Subject Heading: A Systematic Review.

BACKGROUND: Papilledema must be managed distinctly from other causes of optic disc edema (ODE) due to its basis in raised intracranial pressure (ICP). However, evidence indicates that the term "papilledema" is widely misused across specialties to describe ODE without raised ICP. Sources of this misconception remain undiscerned. Because all physicians consult medical databases, our objective was to evaluate whether nonspecific "papilledema" subject heading definitions misleadingly associate articles on other conditions with papilledema proper. METHODS: Systematic review of case reports, prospectively registered on PROSPERO (CRD42022363651). MEDLINE and Embase were searched to July 2022 for any full-length case report indexed to the "papilledema" subject heading. Studies were graded for incorrect indexing, defined as cases lacking evidence for raised ICP. Nonpapilledema diagnoses were assigned to a predefined set of diseases and pathophysiological mechanisms for subsequent comparison. RESULTS: Incorrect indexing occurred in 40.67% of 949 included reports. Embase-derived studies were misindexed significantly less than MEDLINE-derived studies ( P < 0.01). There was also significant heterogeneity in incorrect indexing among specific diseases ( P = 0.0015) and mechanisms ( P = 0.0003). The most commonly misindexed diseases were uveitis (21.24% of errors), optic neuritis (13.47%), and instances with no mention of ODE (13.99%). The most commonly misindexed mechanisms were inflammation (34.97%), other mechanism (e.g., genetic; 25.91%), and ischemia (20.47%). CONCLUSIONS: Database subject headings, especially from MEDLINE, do not adequately distinguish between true papilledema and other causes of ODE. Inflammatory diseases were most often incorrectly indexed among other diseases and mechanisms. Current "papilledema" subject headings should be revised to reduce the probability of misinformation.

A rare case of floated talar head accompanying medial subtalar dislocation.

INTRODUCTION AND IMPORTANCE: Concomitant medial subtalar dislocation and a rotated displaced talar neck fracture may result in poor outcomes. This study aimed to explain this extremely rare injury and assess the clinical outcomes following surgical treatment. CASE PRESENTATION: A 22-year-old Iranian man referred to the emergency department with a gross deformity and pain in his right foot and ankle after a falling from 2 m. Plain radiographs showed a rotated free talar head accompanying medial subtalar dislocation. Closed reduction was performed in the emergency department under sedation. Prompt open reduction and internal fixation of talar fracture was done, after removal of free osseocartilaginous fragments in the subtalar and talonavicular joints. At 25 months postoperatively, the clinical outcomes were assessed using the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale and visual analogue scale for pain which were 73 and 3, respectively. In exam, the patient had a stiffed subtalar joint without talar osteonecrosis or collapse. CLINICAL DISCUSSION: Several osseous and soft tissue barriers could prevent a successful closed reduction of a subtalar dislocation. Associated cartilage injuries or fractures may result in poor clinical outcomes such as persistent pain, limping, osteoarthritis, and osteonecrosis. Immediate open reduction and rigid fixation of associated fractures and resection of small free osseocartilaginous fragments may prevent further soft tissue damages and preserve clinical functions. CONCLUSIONS: Satisfactory clinical outcome could be expected following proper on-time approach to a subtalar dislocation associated with a rotated displaced talar neck fracture.

Clinical outcomes following treatment of deep surgical site infection after fixation of calcaneal fractures: A retrospective case-control study.

INTRODUCTION: Deep surgical site infection (SSI) may be a complication of open reduction and internal fixation (ORIF) of calcaneal fractures. This study aimed to describe the characteristics of patients with deep SSI following ORIF of calcaneal fractures via extensile lateral approach (ELA). We compared clinical outcomes of these patients, with a minimum follow-up of one year after successful treatment of deep SSI with a matched control group. METHODS: In this retrospective case-control study, demographic data, fracture characteristics, bacterial pathogens, medical treatments and surgical approaches were collected, also the outcome was evaluated by the visual analog scale (VAS) for pain, foot function index (FFI) and AOFAS ankle-hindfoot score. The differences in Böhler and Gissane's angles between infected and contralateral feet were measured. By matching a control group of uninfected cases, clinical outcomes were compared between 2 groups using the Mann-Whitney U test. RESULTS: Among 331 calcaneus fractures in 308 patients (mean age, 38.0 ± 13.1; male/female ratio, 5.5), 21 had deep SSI (6.3 %). There were 16 (76.2 %) males and 5 (23.8 %) females with a mean age of 35.1 ± 11.7 years. Thirteen (61.9 %) patients had unilateral fractures. The most common Sanders Type was found to be type II. The most frequent type of detected microorganisms was Staphylococcus species. Intravenous antibiotic therapy, mostly clindamycin, imipenem and vancomycin, based on the microbiological results, was prescribed with a mean±SD duration of 28.1 ± 16.5 days. The mean number of surgical debridements was 1.8 ± 1.3. Implants needed to be removed in 16 (76.2 %) cases. Antibiotic-impregnated bone cement was applied in three (14.3 %) cases. The clinical outcomes of 15 cases (follow up, 35.5 ± 13.8; range, 12.6-64.5 months) were 4.1 ± 2.0, 16.7 ± 12.3 and 77.5 ± 20.8 for VAS for pain, FFI % and AOFAS ankle-hindfoot score, respectively. Comparing with the control group (VAS for pain, 2.3 ± 2.7; FFI %, 12.2 ± 16.6, and AOFAS, 84.6 ± 18.0), only VAS pain was statistically lower in this group (p-value: 0.012). The differences in Böhler and Gissane's angles between both feet of infected cases were - 14.3 ± 17.9 and - 7.7 ± 22.5 (worse in the infected side), respectively. CONCLUSION: Proper on-time approaches to deep infection following ORIF of calcaneal fractures may lead to acceptable clinical and functional outcomes. Sometimes aggressive approaches with intravenous antibiotic therapy, multiple sessions of surgical debridement, removal of implants and antibiotic impregnated cement are necessary to eradicate deep infection. LEVEL OF EVIDENCE: Level III.

A Rare ND5 Mutation Causing Leber's Hereditary Optic Neuropathy.

Mutations to the ND5 gene are uncommonly associated with Leber's hereditary optic neuropathy (LHON). Herein, we describe a 57-year-old man with the m. 13528A>G, p. (Thr398Ala) mutation at the ND5 gene who presented with progressive bilateral vision loss over the course of 3 months. He had a significant history of smoking and alcohol consumption. Visual field testing demonstrated bilateral central scotomas. At 2-year follow-up, his visual acuity improved relative to baseline and temporal optic disc pallor was observed in both eyes. There are scarce reports of this mutation in the literature, and this case report further expands the clinical presentation of the m. 13528A>G mutation at the ND5 gene in patients with LHON phenotype.
