Lipid keratopathy (LK) is a rare ophthalmological condition characterized by a progressive reduction in visual acuity caused by corneal opacification due to central lipid accumulation. LK is characterized by lipid deposits, cholesterol clefts, and neovascularization (NV) leading to disruption in corneal optical quality. LK classification includes a primary and secondary form which depend on pre-existing corneal or systemic disorders and the evidence of NV. Secondary LK is typically associated with a prior occurrence of herpetic infection, such as herpes zoster keratitis. Patients with LK usually present with progressive vision loss and dense cream-colored corneal opacification. Treatment modalities include conservative and surgical approaches focused on corneal NV elimination. When evaluating corneal lipidosis, it is crucial to consider a range of differential diagnoses, including corneal arcus, Schnyder corneal dystrophy, and other corneal deposit conditions. We report a case of a 62-year-old male with herpes zoster keratitis complicated with LK. He presented with painless progressive vision loss and corneal scarring, which raised suspicion about LK diagnosis. This paper emphasizes the importance of correlating clinical and histological findings for accurate LK diagnosis.

(1) Background: Postoperative atrial fibrillation (POAF) is the most common complication following cardiac surgery. It leads to increased perioperative morbidity and costs. Our study aimed to determine the incidence of new-onset POAF in patients undergoing isolated aortic valve replacement (AVR) and develop a multivariate model to identify its predictors. (2) Methods: We conducted a retrospective study including all consecutive patients who underwent isolated AVR at our institution between January 2010 and December 2022. Patients younger than 18, with a history of atrial fibrillation, previous cardiac surgery, or those who underwent concomitant procedures were excluded. Patients were dichotomized into POAF and No POAF groups. Multivariate logistic regression with backward elimination was utilized for predictive modeling. (3) Results: This study included 1108 patients, of which 297 (27%) developed POAF. The final multivariate model identified age, larger valve size, cardiopulmonary bypass time, delayed sternal closure, ventilation time, and intensive care unit stay as predictors of POAF. The model exhibited fair predictive ability (AUC = 0.678, p < 0.001), with the Hosmer–Lemeshow test confirming good model fit (p = 0.655). The overall correct classification percentage was 65.6%. (4) Conclusions: A POAF prediction model offers personalized risk estimates, allowing for tailored management strategies with the potential to enhance patient outcomes and optimize healthcare costs.

Background: This study aims to analyze the impact of the COVID-19 pandemic on the clinical, pathological, and surgical characteristics of acute appendicitis (AA) at the University Hospital Centre (UHC) Zagreb. Methods: This retrospective study analyzed demographic, clinical, and surgical data from consecutive AA patients. Data were collected from an electronic database for two periods: 1 January to 31 December 2019 (pre-COVID-19), and 11 March 2020, to 11 March 2021 (COVID-19 pandemic). Results: During the two study periods, 855 appendectomies were performed, 427 in the pre-pandemic, and 428 during the pandemic. Demographic data were comparable between groups. There was statistically no significant difference in the type of appendectomy (p = 0.33) and the median hospital length of stay (3; (2–5) days, p = 0.08). There was an increase in the conversion rate during the pandemic period (4.2% vs. 7.7%, p = 0.03). The negative appendectomy rate and the incidence of perforated AA did not differ significantly (p = 0.34 for both). Conclusions: We did not observe a significant increase in the rate of AA complications during the COVID-19 pandemic at the UHC Zagreb. This may be attributed to two factors: (1) AA was diagnosed and treated as an emergency, which remained available during the pandemic, and (2) diagnostic and therapeutic protocols remained unaltered. We recommend a laparoscopic approach even during the COVID-19 pandemic.
