Purpose: To describe the treatments used in cases of infectious keratitis and determine the risk factors associated with treatment failure, including prolonged infection duration, treatment modifications, and the need for surgical intervention.
Patients And Methods: This retrospective case series includes culture-proven microbial keratitis cases treated in nine hospitals in the region of Galicia, Spain, between 2010 and 2020.
Results: A total of 654 patients were included.
Purpose: To review the risk factors, clinical characteristics, and microbiological profiles of microbial keratitis cases, as well as the antibiotic resistance patterns of bacterial isolates in the region of Galicia, Spain.
Methods: This retrospective case series includes patients with culture-positive non-viral microbial keratitis between 2010 and 2020, treated at nine hospitals within the region of Galicia, North-West Spain. The standard protocol involved Gram staining for bacterial infections and calcofluor white staining for fungal or amoebal infections, identification by MALDI-TOF mass spectrometry or microscopy, and antimicrobial susceptibility interpreted according to EUCAST or CLSI guidelines.
Article Synopsis
- This study reviewed fungal keratitis cases in Galicia, Spain, focusing on clinical features, risk factors, and treatment from 2010 to 2020.
- Out of 654 infectious keratitis cases, 77 (9.9%) were fungal, predominantly affecting older adults in rural areas, with most infections caused by dermatophyte species.
- Key risk factors included steroid use, recent eye surgeries, and ocular trauma, with delayed diagnosis leading to poor outcomes, stressing the importance of early detection and treatment improvements.
Purpose: The aim of this study is to assess the prognostic value of a classification system that includes the presence of ectopic inner foveal layers and other anatomical variables identified in spectral-domain optical coherence tomography for idiopathic epiretinal membrane (ERM) surgery.
Methods: A descriptive-analytic, longitudinal, retrospective study was conducted on patients with idiopathic ERMs treated with pars plana vitrectomy from January 2017 to December 2021. Clinical data and spectral-domain optical coherence tomography images were reviewed presurgery and 12 months postsurgery.
The substantial increase in the presence of greenhouse gases (GHGs) in the atmosphere has led to the development of several sampling techniques to quantify and characterize the sources of high global warming potential gas emissions. In this context, we developed a new method to estimate the time-averaged concentration of atmospheric methane that employs a long hose to collect a sample of gas by diffusion through one of its ends. We performed numerical simulations to illustrate the basis of our method and to determine the numerical factors required to estimate the time-averaged concentration of methane.
