Pediatric perforated appendicitis diagnosis based on the C-reactive protein/prealbumin ratio.

Pediatric perforated appendicitis, prone to multiple complications, necessitates identifying potential serum biomarkers for early diagnosis and intervention. A cross-sectional study was conducted on patients under 16 with acute appendicitis, admitted to Hainan Women and Children's Medical Center from January 2019 to July 2023. The patients were categorized into perforated and non-perforated groups. Among the 313 included patients, 106 (33.87%, 95% CI 28.59-39.14%) developed perforation. The C-reactive protein to prealbumin ratio (CPA) showed a significant difference between the perforated and non-perforated groups [6.63 (2.9-13.02) vs. 0.7 (0.11-2.18), p < 0.001]. The AUC of CPA on the ROC curve was 0.691 (95% CI 0.513-0.869, p = 0.084) in patients under 4. In patients aged 4-9, the sensitivity of CPA > 3 predicting perforation was 76.2%, with a specificity of 81.6%, and an AUC of 0.816 (95% CI 0.747-0.886, p < 0.001). For patients aged 9-16, the sensitivity of CPA > 2.2 predicting perforation was 85%, with a specificity of 85.7%, and an AUC of 0.919 (95% CI 0.859-0.979, p < 0.001). CPA > 3 and CPA > 2.2 can predict perforated appendicitis in patients aged 4-9 and 9-16, respectively.

Factors associated with in-hospital recurrence of intestinal intussusception in children.

BACKGROUND: A minority of children experience in-hospital recurrence of intestinal intussusception after treatment. This study investigated the factors associated with in-hospital recurrence of intussusception in pediatric patients in China. METHODS: This retrospective study included patients aged 0-18 years-old with intestinal intussusception treated at Hainan Women and Children's Medical Center between January 2019 and December 2019. Demographic and clinical characteristics were extracted from the medical records. Factors associated with in-hospital recurrence of intussusception were identified by logistic regression analysis. RESULTS: The analysis included 624 children (400 boys) with a median age of 1.8 years (range, 2 months and 6 days to 9 years). Seventy-three children (11.7%) had in-hospital recurrence of intussusception after successful reduction with air enema. Multivariate logistic regression analysis identified age > 1 year-old (odds ratio [OR]: 7.65; 95% confidence interval [95%CI]: 2.70-21.71; P < 0.001), secondary intestinal intussusception (OR: 14.40; 95%CI: 4.31-48.14; P < 0.001) and mesenteric lymph node enlargement (OR: 1.90; 95%CI: 1.13-3.18; P = 0.015) as factors independently associated with in-hospital recurrence of intussusception. CONCLUSIONS: Age > 1 year-old, secondary intussusception and mesenteric lymph node enlargement were independently associated with increased odds of in-hospital recurrence of intussusception after successful reduction with air enema.
