Unilateral Eye Findings: A Rare Herald of Acute Leukemia

BACKGROUND/AIM: Unilateral choroidal infiltration as the initial manifestation of leukemic relapse in adults is rare, particularly after an extended period of remission. This report describes this unique ophthalmic presentation, highlights the associated diagnostic challenges, and reviews the literature. METHODS: Two cases are described and an extensive literature review was conducted. RESULTS: A 59-year-old male with acute lymphoid leukemia, in remission for 18 months, presented with unilateral scleritis, exudative retinal detachment, and choroidal thickening. A 57-year-old male with a history of acute myeloid leukemia, in remission for 4 years, presented with unilateral choroidal thickening leading to secondary angle closure. In both cases, there was a significant lag from the onset of eye symptoms to establishing a systemic diagnosis of acute leukemia, leading to a delay in definitive systemic treatment, despite a high suspicion of disease based on ophthalmic findings. CONCLUSIONS: These two cases illustrate the fundus findings consistent with leukemic choroidal infiltration that can represent the first sign of relapsed leukemia. The successful treatment of these patients hinges on collaboration between ophthalmologists and oncologists to optimize patient outcomes, highlighting the need for both groups to be aware of this rare ophthalmic presentation

Validation of a classification system for causes of death in critical care: an assessment of inter-rater reliability

Objective: Trials in critical care have previously used unvalidated systems to classify cause of death. We aimed to provide initial validation of a method to classify cause of death in intensive care unit patients. Design, setting and participants: One hundred case scenarios of patients who died in an ICU were presented online to raters, who were asked to select a proximate and an underlying cause of death for each, using the ICU Deaths Classification and Reason (ICU-DECLARE) system. We evaluated two methods of categorising proximate cause of death (designated Lists A and B) and one method of categorising underlying cause of death. Raters were ICU specialists and research coordinators from Australia, New Zealand and the United Kingdom. Main outcome measures: Inter-rater reliability, as measured by the Fleiss multirater kappa, and the median proportion of raters choosing the most likely diagnosis (defined as the most popular classification choice in each case). Results: Across all raters and cases, for proximate cause of death List A, kappa was 0.54 (95% Cl, 0.49–0.60), and for proximate cause of death List B, kappa was 0.58 (95% Cl, 0.53–0.63). For the underlying cause of death, kappa was 0.48 (95% Cl, 0.44–0.53). The median proportion of raters choosing the most likely diagnosis for proximate cause of death, List A, was 77.5% (interquartile range [IQR], 60.0%–93.8%), and the median proportion choosing the most likely diagnosis for proximate cause of death, List B, was 82.5% (IQR, 60.0%–92.5%). The median proportion choosing the most likely diagnosis for underlying cause was 65.0% (IQR, 50.0%–81.3%). Kappa and median agreement were similar between countries. ICU specialists showed higher kappa and median agreement than research coordinators. Conclusions: The ICU-DECLARE system allowed ICU doctors to classify the proximate cause of death of patients who died in the ICU with substantial reliability
