The incidence of ROP observed in this study was higher than that in developed countries and relatively more mature infants were affected. Criteria including gestational age of less than 34 weeks or birth weight of less than 2,000 g would have identified all infants who were at risk.

Background: Despite the existence of detailed consensus guidelines, challenges remain regarding efficient, appropriate, and safe imaging methods for the diagnosis of suspected pulmonary embolism.Aims: To investigate the role of the wedge sign, B-lines, and pleural effusion seen on bedside lung ultrasound in the diagnosis of pulmonary embolism.Study Design: Diagnostic accuracy study.Methods: During the first evaluation of patients with suspected pulmonary embolism, bedside lung ultrasound was performed, and the B-lines, wedge sign, and pleural effusion were investigated. Computed tomography angiography was used as a confirmatory test and was compared with the lung ultrasound findings.Results: Pulmonary embolism was detected in 38 (38%) patients. In the comparison of bedside lung ultrasound results, statistically significant differences were found between the groups in terms of the B-lines and wedge sign (p=0.005 and p<0.001, respectively). There were no significant differences in terms of effusion (p=0.234). Comparison of these findings with computed tomography angiography of the chest showed weak negative correlations between the groups in terms of B-lines (r=-0297) and a moderately positive correlation in terms of the wedge sign (r=0.523). The sensitivity, specificity, and positive and negative predictive values of lung ultrasound findings alone were low. In the logistic regression analysis, the wedge sign (p<0.01, OR=69.45, 95% CI=6.94-695.17) and B-line (p=0.033, OR=1.96, 95% CI=0.41-8.40) were found to be effective in the diagnosis of pulmonary embolism.Conclusion: Although the role of lung ultrasound has been increasing in the management of critically ill patients, its value is limited and cannot replace the gold standard tests in the diagnosis of pulmonary embolism.

To assess the relationships between visual acuity (VA), fluorescein angiographic parameters and optical coherence tomography (OCT) patterns in exudative age-related macular degeneration (AMD). Fifty eyes with confirmed diagnosis of new exudative AMD who underwent fluorescein angiography (FA) and OCT evaluation were reviewed retrospectively. The greatest linear diameter of lesion (GLD) by FA and central foveal thickness (CFT) by OCT were measured. The OCT scans were evaluated for the presence of diffuse retinal thickening (D), cystic spaces (C), subretinal fluid (S) and pigment epithelial detachment (P) and five OCT patterns were detected (D + S; C; C + S; P + C + S; P + D + S). Angiographic classification of choroidal neovascularizations was performed. Correlations were statistically significant for VA and CFT in all patients whereas VA and GLD correlation was statistically significant only in predominantly classic and minimal classic lesions. The lowest VA values were detected in patients with COCT pattern and/or predominantly classic lesion type by FA. The OCT and FA findings when evaluated simultaneously may provide information regarding visual function in AMD.

Background. Syncope is a common symptom in emergency department patients. Among various etiological factors, cardiac causes have the highest risk of mortality. The corrected QT interval is considered an independent predictor of mortality for many diseases. Objectives. Analyze QT interval analysis of patients presenting to the emergency department with syncope. Methods. In this prospective observational study, patients who presented to the emergency department with syncope between January 1, 2018, and January 1, 2019 were included. Results. The median age was 64 (49-78) years, and 58.8% of patients were male. The corrected QT interval (QTc) in patients with coronary artery disease and chronic obstructive pulmonary disease was longer than those without. There was no statistically significant association between hypertension, diabetes, stroke, thyroid disease, and prolonged QTc. Patients who did not survive had significantly prolonged QT intervals. According to ROC analysis, sensitivity of >440.5 ms QTc values in predicting mortality was 86% and specificity was 71% ( AUC = 0.815 ; 95 % CI = 0.71 − 0.91 ; p < 0.001 ). Conclusions. Patients admitted to emergency department with syncope and a prolonged QTc are associated with a higher mortality rate and thus can provide us with an important guide for the management of these patients.
