purpose: to assess the efficacy of polyhexamethylene biguanide (phmb) in treating acanthamoeba keratitis (ak) and also to identify related factors affecting final visual outcome in ak patients treated with phmb methods: in these interventional case series study, 27 eyes of 25 patients with ak received phmb 0.02% and divided into two groups according to the final visual acuity (va) va equal to o...

SIR, -I read with great interest the paper by Wong and Kaye on a suggested chart for visual acuity screening.' However, I was surprised to find that they recommended widespread clinical use of this chart without any clinical data to confirm its suitability. The statistical argument they use is compelling, but surely a comparison with other methods of acuity testing should be undertaken to confi...

Goldenhar syndrome is a rare clinical disturbance with a wide range of clinical manifestations. We report on a 6-year-old male with peculiar retinal presentation of Goldenhar syndrome. The patient was referred to Ophthalmology for central scotoma in the left eye, where visual acuity was 20/100. Fundus examination was unremarkable, except for yellowish material in the central macula. SD-OCT reve...

Effective triage is critical to mitigating the effect of increased volume by accurately determining patient acuity, need for resources, and establishing effective acuity-based prioritization. The purpose this retrospective study was determine whether historical EHR data can be extracted synthesized with clinical natural language processing (C-NLP) latest ML algorithms (KATE) produce highly accu...

BACKGROUND New resident work-hour restrictions are expected to result in further increases in the number of handoffs between inpatient care providers, a known risk factor for poor outcomes. Strategies for improving the accuracy and efficiency of provider sign-outs are needed. OBJECTIVE To develop and test a judgment-based scale for conveying the risk of clinical deterioration. DESIGN Prospe...
