Retrospective Analysis of Physician-based Surveys Published in OPRS.

PURPOSE: To review physician-based clinical surveys published in Ophthalmic Plastic and Reconstructive Surgery. METHODS: Complementary Ovid and PubMed searches of Ophthalmic Plastic and Reconstructive Surgery journal content were performed for the term "survey." Results were narrowed to studies that specifically addressed physicians' clinical practices. This search resulted in 162 articles, and after dual-investigator independent screening, 13 surveys met inclusion criteria. RESULTS: Of the 13 surveys published from 2007 to January 2017, 6 were published since 2015, showing an increased trend in survey-based publications. Topics included assessing practice patterns regarding eyelid disorders, thyroid eye disease, optic nerve sheath fenestration, anophthalmic socket, and diagnosing lacrimal disorders. Average response rate was 38.7% (range 17.5-60%), with 201 average number of replies (range 72-310). Nine out of 13 surveys included some form of statistical analysis with the remainder presenting data in percentages. CONCLUSIONS: There has been an increased rate of survey-type publications in Ophthalmic Plastic and Reconstructive Surgery over the past 10 years. The low response rate and frequent lack of statistical analysis raise concerns regarding the validity and usefulness of such studies. The authors believe that survey studies can be improved through better standardization and the use of author guidelines. They have made specific recommendations to improve the impact of survey papers in the future.

Xeroderma Pigmentosum Group C Deficiency Alters Cigarette Smoke DNA Damage Cell Fate and Accelerates Emphysema Development.

Cigarette smoke (CS) exposure is a major risk factor for the development of emphysema, a common disease characterized by loss of cells comprising the lung parenchyma. The mechanisms of cell injury leading to emphysema are not completely understood but are thought to involve persistent cytotoxic or mutagenic DNA damage induced by CS. Using complementary cell culture and mouse models of CS exposure, we investigated the role of the DNA repair protein, xeroderma pigmentosum group C (XPC), on CS-induced DNA damage repair and emphysema. Expression of XPC was decreased in mouse lungs after chronic CS exposure and XPC knockdown in cultured human lung epithelial cells decreased their survival after CS exposure due to activation of the intrinsic apoptosis pathway. Similarly, cell autophagy and apoptosis were increased in XPC-deficient mouse lungs and were further increased by CS exposure. XPC deficiency was associated with structural and functional changes characteristic of emphysema, which were worsened by age, similar to levels observed with chronic CS exposure. Taken together, these findings suggest that repair of DNA damage by XPC plays an important and previously unrecognized role in the maintenance of alveolar structures. These findings support that loss of XPC, possibly due to chronic CS exposure, promotes emphysema development and further supports a link between DNA damage, impaired DNA repair, and development of emphysema.
