Background: Diagnosis of appendicitis in children is clinically challenging. Computed tomography (CT) is the gold standard for diagnosis; however, radiation exposure early in life is a concern with this technique. Therefore, in this study, we aimed to evaluate the diagnostic reliability of low-dose CT, pediatric appendicitis score (PAS), and abdominal ultrasound (US) in children with acute appendicitis, to reach a safe diagnosis.

The objective of this case series was to investigate the prognostic role of sUA in patients with acute asthma exacerbations and the link between sUA and spirometric lung tests.
Patients And Methods: This cross-sectional observational study included 120 patients with acute asthma exacerbations and 120 controls, categorized according to peak expiratory flow rate into moderate, and severe and life-threatening asthma.
Article Synopsis
- The study aimed to assess the effectiveness of single-photon emission computed tomography (SPECT) using technetium-99 m tetrofosmin as a non-invasive alternative to coronary angiography in detecting myocardial ischemia in Kawasaki disease patients.
- The research involved 21 patients categorized into three groups based on their coronary artery conditions, with follow-ups showing notable improvements in myocardial perfusion after bypass surgery.
- Results indicated that SPECT demonstrated high sensitivity (94%), specificity (100%), and accuracy (95%), suggesting it is a reliable method for evaluating coronary artery lesions and post-surgical outcomes.
