Background And Aims: Providing respiratory support (RS) to patients may improve their oxygenation and ventilation, reducing the work of breathing. Emergency department (ED) patients often need RS; COVID-19 has heightened this need. Patients receiving RS may need escalation of their treatment; hence, studies considering the prevalence of escalation are warranted.

Purpose: To identify the demographic and clinical associations of patients presenting with herpetic keratitis in New Zealand compared with presentations of presumed microbial keratitis.

Methods: A prospective, 6-month, observational case series of presumed microbial keratitis (including marginal keratitis), specifically identifying all cases of herpes simplex and varicella zoster keratitis attending an emergency eye clinic was conducted. Main outcome measures included demographics, presenting signs and symptoms, and medical, ocular, and drug history.

Fungal keratitis (FK) typically requires intensive therapy with topical antifungal agents. To date, evidence from clinical trials has been conflicting with respect to the most effective topical antifungal drug in the treatment of FK. Therefore, a systematic review and meta-analysis of randomized controlled trials (RCTS) using the Cochrane methodology was undertaken to evaluate the effectiveness of topical antifungals in management of FK.

Background: There is lack of consensus from randomized controlled trials on the efficacy of antivirals in the management of herpes zoster. Therefore, a systematic review and meta-analysis was undertaken to provide better understanding of effectiveness of antivirals in management of herpes zoster.

Methods: A total of 12 randomized controlled trials with 7,277 patients were included in the review.
