RESUMO
Many children grow up hearing multiple languages, learning words in each. How does the number of languages being learned affect multilinguals' vocabulary development? In a pre-registered study, we compared productive vocabularies of bilingual (n = 170) and trilingual (n = 20) toddlers aged 17-33 months growing up in a bilingual community where both French and English are spoken. We hypothesized that because trilinguals have reduced input in French and English due to time spent hearing their third language, they would have smaller French-English vocabulary sizes than bilinguals. Trilinguals produced on average 2/3 of the number of words in these languages that bilinguals did: however, this difference was not statistically robust due to large levels of variability. Follow-up analyses did, however, indicate a relationship between input quantity and vocabulary size. Our results indicate that similar factors contribute to vocabulary development across toddlers regardless of the number of languages being acquired.

Background: Gender disparities in the field of ophthalmology have been increasingly recognized. Although mentorship has been proposed as a contributing factor, there are limited data on the differences in mentorship experiences by gender among ophthalmologists. Objective: The purpose of this study was to evaluate gender disparities in mentorship experiences among ophthalmologists, and the impact of mentorship disparities on career outcomes. Design: Prospective, cross-sectional study. Setting: Web-based survey distributed through ophthalmology listservs. Participants: Ophthalmologists and ophthalmologists-in-training who completed the survey. Exposure: Training and practicing in the field of ophthalmology. Main Outcome Measures: Mentorship score based on 10 items from a previously published scale of mentorship quality and self-reported career outcomes (income, job satisfaction, achievement of career goals, and support to achieve future career goals). Results: We received survey responses from 202 male and 245 female ophthalmologists. Female ophthalmologists reported significantly lower mentorship satisfaction and worse quality of mentorship (p < 0.03). Female ophthalmologists also reported significantly lower income, worse job satisfaction, and lower rates of goal achievement and support to achieve future goals; all of these career outcomes, except income level, were partly mediated by mentorship score (mediation effect ranged from 29% to 68%, p < 0.014). Conclusions and Relevance: Gender-based inequities in achievement of career goals and job satisfaction are partly mediated by disparities in mentorship. Therefore, focused mentorship of women in ophthalmology at all career stages is imperative to reduce these inequities.

Glaucoma following penetrating keratoplasty (PKP) remains the leading cause of blindness following PKP. Patients with post-PKP glaucoma can be managed medically and surgically. Evidence studying glaucoma surgical techniques following PKP is limited, but suggests the possibility for high-risk complications, including graft failure. Minimally invasive glaucoma surgeries offer an alternative. We report the first case of post-PKP glaucoma managed with gonioscopy-assisted transluminal trabeculotomy (GATT). The patient was a 33-year-old man with a history of keratoconus who underwent PKP in his right eye. On presentation, his visual acuity was 20/60 and intraocular pressure was 48 mm Hg OD. He underwent GATT and cataract phacoemulsification. Following 22 months of follow-up, the patient's visual acuity was 20/30 and intraocular pressure 13 mm Hg, off all glaucoma medications. This case demonstrates GATT may be a good surgical option for post-PKP glaucoma, given the ability to perform future incisional surgery and avoidance of high-risk complications associated with traditional glaucoma surgeries.

OBJECTIVES: The Goldmann applanation tonometer is the gold standard for measuring intraocular pressure and a possible vector for the transmission of infectious diseases. The purpose of this study is to consolidate the evidence pertaining to the disinfection of Goldmann tonometers in an effort to facilitate an informed discussion regarding public policy in this important area. DESIGN: Systematic review. METHODS: An exhaustive literature review was undertaken to identify primary-level research that assesses the effectiveness of different agents used in the disinfection of Goldmann applanation tonometer prisms. Seven discrete databases were reviewed by 2 independent researchers, and a symmetrical screening process was used to identify and review all pertinent studies. RESULTS: Our review identified only 19 primary-level studies that relate specifically to the disinfection of Goldmann tonometer prisms. These studies are largely heterogeneous with regard to the pathogens and disinfectants that were tested and the experimental protocols that were employed. Accordingly, definitive conclusions as to the optimal agent cannot be made on this basis. Furthermore, the results of our review reinforce previous suggestions that only adenovirus has been transmitted between patients via the Goldmann tonometer. CONCLUSIONS: The present state of the literature does not permit a definitive conclusion regarding optimal disinfection agent for Goldmann applanation tonometer prisms. Further well-constructed studies are required to better delineate the effectiveness of disinfectants in the specific context of tonometer prisms.
