Longitudinal multimodal imaging of bilateral diffuse uveal melanocytic proliferation secondary to gallbladder adenocarcinoma.

Purpose: To present the longitudinal, multimodal imaging of Bilateral Diffuse Uveal Melanocytic Proliferation secondary to gallbladder carcinoma over a 17 month period, demonstrating the natural history, the evolution with treatment and salient features to support timely diagnosis of this condition with life-threatening associations.

Observations: A systemically well 73 year old woman presented with a 2 month history of progressive visual loss in the right eye. We report the initial findings on clinical examination and with retinal imaging including fluorescein and indocyanine angiography, optical coherence tomography and autoflourescence.

The role of CPAP as a potential bridge to invasive ventilation and as a ceiling-of-care for patients hospitalized with Covid-19-An observational study.

Background: Continuous positive airway pressure (CPAP) ventilation may be used as a potential bridge to invasive mechanical ventilation (IMV), or as a ceiling-of-care for persistent hypoxaemia despite standard oxygen therapy, according to UK guidelines. We examined the association of mode of respiratory support and ceiling-of-care on mortality.

Methods: We conducted a retrospective cohort analysis of routinely collected de-identified data of adults with nasal/throat SARs-CoV-2 swab-positive results, at the Calderdale and Huddersfield NHS Foundation Trust between 10th March-19th April 2020 (outcomes determined on 22nd May).
