Purpose: Traumatic brain injury (TBI) can cause significant morbidity and mortality in the pediatric population. Brain CT is the mainstay in the diagnosis of intracranial hemorrhage (ICH). The aim of this study was to explore the clinical characteristics that can predict ICH on brain CT in pediatric TBI patients, to assist physicians in deciding on the use of brain CT., Methods: A total of 475 pediatric TBI patients who underwent brain CT within 24 h after injury from January 2012 to December 2021 in the level 1 trauma center in Thailand were included in this cross-sectional study. Clinical data and brain CT findings were collected. Logistic regression analysis was applied to evaluate clinical characteristics that could predict ICH on brain CT in pediatric TBI patients. A p value was less than 0.05 being indicated that the difference is statistically significant. R software version 3.6.1 was used to statistical analysis., Results: The included cases have a median (Q 1 , Q 3 ) age of 7.7 (3.5, 12.6) years. ICH was found in 98 (20.6%) pediatric patients based on brain CT findings. On multivariable analysis, high blunt energy injury (odds ratio (OR) = 2.79, 95% CI 1.27 - 6.11, p = 0.010), motor vehicle accidents (OR = 2.04, 95% CI: 1.14 - 3.67, p = 0.017), Glasgow coma scale score <13 (OR = 4.28, 95% CI: 1.87 - 9.78, p < 0.001), palpable skull fractures (OR = 7.30, 95% CI: 1.44 - 37.04, p = 0.016), signs of basilar skull fracture (OR = 6.10, 95% CI: 2.16 - 17.24, p < 0.001), and vomiting ≥ 3 times (OR = 2.60, 95% CI: 1.17 - 5.77, p = 0.022) were statistically significant predictive factors for ICH in pediatric TBI patients., Conclusion: These factors might aid clinicians in making an appropriate decision regarding the use of brain CT in pediatric TBI cases., (Copyright © 2024.

Background: Most common surgical complications in cholecystectomy are surgical site infections (SSIs). SSIs have many factors, including patient, surgical, and disease factors. This study aims to find the factors which relate to SSIs 30 days after cholecystectomy and contribute to the scoring system to predict SSIs., Methods and Material: The data of patients who underwent cholecystectomy from January 2015 to December 2019 were retrospectively collected from a prospectively collected infectious control registry. The SSI was defined following the CDC criteria and assessed before discharge and at a 1-month follow-up. Variables that were independently predictive of the increased SSIs were included in the risk score., Results: The patients who underwent cholecystectomy were 949, which were divided into 28 patients who had SSIs and 921 who had no SSIs. The rate of SSIs was 3%. The factors related to SSI in cholecystectomy were age ≥ 60 years (p = 0.045), history of smoking (p = 0.004), retrieval bag use (p = 0.005), preoperative ERCP (p = 0.02), and wound class III and IV (p = 0.007). Risk assessment was using five variables (WEBAC): (1) wound classifications, (2) preoperative ERCP, (3) retrieval plastic bag use, (4) aged ≥ 60 years, and (5) history of smoking (cigarette). If patients were aged ≥ 60 years and had a history of smoking, no plastic bag use, preoperative ERCP, or wound class III or IV, these parameters would all be scored 1 each. The WEBAC score revealed the probability of SSIs in cholecystectomy wounds., Conclusion: The WEBAC score represents a convenient and simple tool to predict the probability of SSI in the patients who underwent cholecystectomy and might increase the surgeons' awareness of postoperative SSI., (© 2023.

Background: Acute appendicitis is the most common cause of acute lower abdominal pain leading patients to the emergency department. This study aims to find the negative appendectomy rate in patients diagnosed with acute appendicitis from 2015 to 2019., Methods: This study was a retrospective cohort study in the patients preoperatively diagnosed with acute appendicitis and underwent appendectomy from January 2015 to December 2019. Negative appendectomy is defined as the final pathologic results confirmed normal, congestion or peri-appendicitis., Results: The study population was 892 patients which was 54.3% female. The five-year negative appendectomy rate was 8.6% (n = 77) and 70% in female (n = 54). The factors associated with increasing the negative appendectomy rate were female (OR 2.23, P = 0.003), age ≤ 40 years old (OR 2.35, P = 0.003), and no history of diarrhea (OR 2.42, P = 0.017). Whereas the factors related to decline in the negative appendectomy rate were white blood cell count (WBC) [Formula: see text] 10,000 (OR 0.39, P = 0.016), neutrophil (N) [Formula: see text] 75% (OR 0.28, P < 0.001), and positive appendicitis from ultrasonography of abdomen (OR 0.04, P < 0.001) or computed tomography of abdomen (OR 0.07, P < 0.001)., Conclusion: The negative appendectomy rate was less than 10% in this study. Female, age 40 ≤ years old and history of diarrhea were related to increase in negative appendectomy. The factors that related to decline in negative appendectomy were leukocytosis with cells shift to the left, positive acute appendicitis from abdominal ultrasonography and CT scan. However, to request the further imaging studies to diagnose patients with suspected acute appendicitis depends on the risk and benefit to each patient and the choice of investigation., (© 2022.
