RESUMEN

Restrictive strabismus is a known complication of orbitozygomatic craniotomy. However, a pseudo-Duane syndrome has not been described following this procedure. The authors describe a 58-year-old woman who after craniotomy developed incomitant left exotropia with an adduction deficit; the globe retracted and palpebral fissure narrowed with attempted ocular adduction.

RESUMEN

PURPOSE: To assess patient satisfaction within pediatric ophthalmology and identify trends in patient sentiment. METHODS: Pediatric ophthalmologists in the United States were identified using the American Association for Pediatric Ophthalmology and Strabismus member directory. Demographic data were recorded using publicly available websites. Online written reviews and Stars ratings were obtained from Healthgrades.com. A sentiment analysis package, Valence Aware Dictionary for Sentimental Reasoning (VADER), was used to generate a compound score of reviews, and word frequency analyses were applied. RESULTS: A total of 377 pediatric ophthalmologists (2,640 online reviews) were evaluated. Physicians received an average of 4.22/5 Stars and a compound sentiment score of 0.56, indicating positive sentiment. No differences in scores were observed by gender or location, although physicians with fewer years in practice had higher Stars ratings compared to peers (P < .001). The three most common words in the word frequency analysis of all reviews were "surgery," "staff," and "time," with heavy emphasis on bedside manner and addressing patient concerns. CONCLUSIONS: This study demonstrates overall high patient satisfaction in pediatric ophthalmology care, with differences in sentiment based on physician demographic features. The study highlights that patient perspective is influenced by non-clinical features of care. These data may be used by pediatric ophthalmologists seeking to improve health care delivery.

RESUMEN

Aging muscle experiences functional decline in part mediated by impaired mitochondrial ADP sensitivity. Elamipretide (ELAM) rapidly improves physiological and mitochondrial function in aging and binds directly to the mitochondrial ADP transporter ANT. We hypothesized that ELAM improves ADP sensitivity in aging leading to rescued physiological function. We measured the response to ADP stimulation in young and old muscle mitochondria with ELAM treatment, in vivo heart and muscle function, and compared protein abundance, phosphorylation, and S-glutathionylation of ADP/ATP pathway proteins. ELAM treatment increased ADP sensitivity in old muscle mitochondria by increasing uptake of ADP through the ANT and rescued muscle force and heart systolic function. Protein abundance in the ADP/ATP transport and synthesis pathway was unchanged, but ELAM treatment decreased protein s-glutathionylation incuding of ANT. Mitochondrial ADP sensitivity is rapidly modifiable. This research supports the hypothesis that ELAM improves ANT function in aging and links mitochondrial ADP sensitivity to physiological function. ELAM binds directly to ANT and ATP synthase and ELAM treatment improves ADP sensitivity, increases ATP production, and improves physiological function in old muscles.

RESUMEN

Genomic, transcriptomic and proteomic approaches have been used to gain insight into molecular underpinnings of aging in laboratory animals and in humans. However, protein function in biological systems is under complex regulation and includes factors besides abundance levels, such as modifications, localization, conformation and protein-protein interactions. By making use of quantitative chemical cross-linking technologies, we show that changes in the muscle mitochondrial interactome contribute to mitochondrial functional decline in aging in female mice. Specifically, we identify age-related changes in protein cross-links relating to assembly of electron transport system complexes I and IV, activity of glutamate dehydrogenase, and coenzyme-A binding in fatty acid ß-oxidation and tricarboxylic acid cycle enzymes. These changes show a remarkable correlation with complex I respiration differences within the same young-old animal pairs. Each observed cross-link can serve as a protein conformational or protein-protein interaction probe in future studies, which will provide further molecular insights into commonly observed age-related phenotypic differences. Therefore, this data set could become a valuable resource for additional in-depth molecular studies that are needed to better understand complex age-related molecular changes.

RESUMEN

PURPOSE: To determine and analyze the 100 most cited articles in pediatric ophthalmology. METHODS: A literature search was conducted using the ISI Web of Science database on the top 100 most cited articles in pediatric ophthalmology. RESULTS: The 100 most cited articles were published between 1941 and 2018, with the greatest number published in both 2005 and 2012. A total of 29,731 citations were generated during the study period. There has been a significant increase in citations annually since 1941, with a peak number of citations in 2021 with 2,629 citations. Myopia, retinopathy of prematurity, and other forms of refractive error were the topics most studied and cited in these articles. Most of the articles were classified as either large cohort prospective/retrospective studies (34) or randomized clinical trials (19), with case reports/series being the least frequent (7). Investigative Ophthalmology & Visual Science (23), JAMA Ophthalmology (22), and Ophthalmology (22) published the majority of the articles. Institutions that conducted the majority of the studies presented include the National Eye Institute (10), the Ohio State University College of Optometry (9), and the Oregon Health & Science University (6). CONCLUSIONS: This bibliometric analysis provides a unique historical perspective of the literature in the field of pediatric ophthalmology that has not been studied before. The research in the field of pediatric ophthalmology is advancing quickly, with most articles and citations occurring within the past 15 years. The strong focus on prospective cohort studies and clinical trials reveals the importance of advancing the treatment of critical disease within the field of pediatric ophthalmology.

RESUMEN

PURPOSE: To evaluate whether cycloplegic autorefraction can provide similar results as cycloplegic retinoscopy, allowing more comprehensive ophthalmologists to be comfortable in managing pediatric refractive error and refractive amblyopia. METHODS: This retrospective chart review was performed to determine the mean difference in sphere, cylinder, and axis between cycloplegic autorefraction and retinoscopy, both of which were obtained on the same eye at least 30 minutes after cycloplegia and dilation with a mixed solution of tropicamide, cyclopentolate, and phenylephrine. RESULTS: A total of 34 eyes (18 right, 16 left) from 18 patients were included in the analysis. Mean sphere difference between cycloplegic autorefraction and retinoscopy was 0.044 ± 0.278 diopters (D) (95% CI: -1.275 to 1.363 D), mean cylinder difference was -0.081 ± 0.236 D (95% CI: -0.706 to 0.544 D), and mean axis difference was 7.059 ± 19.676 degrees (95% CI: -32.527 to 38.878 degrees). Mean differences in sphere, cylinder, and axis were not statistically significant (P = .362, .0541, and .377, respectively). CONCLUSIONS: In this small sample population, cycloplegic autorefraction was comparable to cycloplegic retinoscopy. Recognition of amblyopia should still prompt evaluation by a pediatric ophthalmologist. Further research is necessary to confirm whether uncomplicated refractive error in children may be sufficiently detected and managed by a comprehensive ophthalmologist.
