ABSTRACT

This pilot study aimed to identify quantitative electroencephalographic (qEEG) biomarkers for children and adolescents with attention deficit hyperactivity disorder (ADHD). We examined whether qEEG power correlates with the behavioral symptoms. We included 89 children with ADHD and 77 healthy children as a control group. We conducted EEG spectral analysis in the eyes-closed and eyes-opened conditions and compared the findings with a normative database (Human Brain Index). We measured behavioral parameters by using scales proposed by Barkley. The findings revealed an age-dependent decrease in qEEG power in children with ADHD. We found significant discrimination between children with ADHD and healthy children in the theta/beta ratio and theta activity in the frontal area. We found a notable increasing trend in beta activity across two age groups (6-10 years and > 10 years). Correlation analysis showed an association between qEEG power and hyperactivity in younger children with ADHD, while theta activity in the frontal region correlated positively with hyperactivity. The qEEG power of children with ADHD decreased gradually as age increased, and these changes were related to their symptoms. This pilot study suggests that qEEG differences between children with ADHD and healthy children may serve as a sensitive diagnostic tool, depending on the child's age. Further research building upon these findings could deepen our understanding of ADHD and its neural correlates.

ABSTRACT

OBJECTIVE: Appendiceal perforation has significant effects on perioperative morbidity and postoperative outcome. The present study aimed to identify possible predictive factors associated with perforated appendicitis (PA) in children at admission in the emergency department (ED). METHODS: In this retrospective observational cohort study, consecutive medical records of children <18 years old with surgically and histopathologically confirmed acute appendicitis (AA) over three years (2013-2015) were analyzed. Patients were divided into two groups: PA and non-perforated appendicitis (NPA). The differences between the two groups and potential predictors of PA were explored using univariate and multivariate analyses. RESULTS: During the study period, 295 patients underwent an appendectomy and had confirmatory AA diagnoses. Ninety-two patients had a PA (31.2%). In the univariate analysis, male gender, vomiting, diarrhea, fever, elevated white blood cell count (WBC) levels, and high C-reactive protein (CRP) were identified as predictors of PA. In the multivariate analysis, male gender (odds ratio [OR]: 3.133; 95% confidence interval [CI]: 1.610-6.096); vomiting (OR: 2.346; 95% CI: 1.141-4.822); diarrhea (OR: 4.549; 95% CI: 1.850-11.181); fever (OR: 3.429; 95% CI: 1.765-6.663); elevated WBC (OR: 2.962; 95% CI: 1.491-5.884) and elevated CRP (OR: 3.061; 95% CI: 1.267-7.396) were variables that predicted the PA in children. CONCLUSION: Our data indicate that several clinical and biochemical parameters can reliably distinguish between pediatric PA and NPA at admission in the emergency department.
