The early diagnosis and treatment of foreign body aspiration (FBA) can significantly improve the overall prognosis of children. There are significant differences in the epidemiology and clinical characteristics of FBA in different regions. Therefore, we conducted a real-world study in the western region of China with over 4000 patients. The aim of this study was to improve the understanding of FBA in terms of its types, the specific months of its occurrence, and the distribution of primary caregiver characteristics in western China. We collected the clinical and epidemiological data of children who were diagnosed with FBA in our hospital over the past 20 years through a big data centre. We matched the data of healthy children who underwent routine physical examinations at the paediatric health clinic during the same period to analyse the differences in the data of actual guardians. A total of 4227 patients from five provinces were included in this study. Foreign bodies were removed by rigid bronchoscopy in 99.4% (4202/4227) of patients, with a median age of 19 months and a median surgical duration 16 min. January was the most common month of onset for 1725 patients, followed by February, with 1027 patients. The most common types of foreign objects were melon peanuts, seeds and walnuts, accounting for 47.2%, 15.3%, and 10.2%, respectively. In the FBA group, the proportion of grandparents who were primary caregivers was 70.33% (2973/4227), which was significantly greater than the 63.05% in the healthy group (2665/4227) (P < 0.01). FBA most commonly occurs in January and February. More than 60% of FBAs occur between the ages of 1 and 2 years, and the incidence of FBA may be greater in children who are cared for by grandparents. A rigid bronchoscope can be used to remove most aspirated foreign bodies in a median of 16 min. [ABSTRACT FROM AUTHOR]

Objectives: The occurrence of pulmonary infection after congenital heart disease (CHD) surgery can lead to significant increases in intensive care in cardiac intensive care unit (CICU) retention time, medical expenses, and risk of death risk. We hypothesized that patients with a high risk of pulmonary infection could be screened out as early after surgery. Hence, we developed and validated the first risk prediction model to verify our hypothesis.Methods: Patients who underwent CHD surgery from October 2012 to December 2017 in the Children's Hospital of Chongqing Medical University were included in the development group, while patients who underwent CHD surgery from December 2017 to October 2018 were included in the validation group. The independent risk factors associated with pulmonary infection following CHD surgery were screened using univariable and multivariable logistic regression analyses. The corresponding nomogram prediction model was constructed according to the regression coefficients. Model discrimination was evaluated by the area under the receiver operating characteristic curve (ROC) (AUC), and model calibration was conducted with the Hosmer-Lemeshow test.Results: The univariate and multivariate logistic regression analyses identified the following six independent risk factors of pulmonary infection after cardiac surgery: age, weight, preoperative hospital stay, risk-adjusted classification for congenital heart surgery (RACHS)-1 score, cardiopulmonary bypass time and intraoperative blood transfusion. We established an individualized prediction model of pulmonary infection following cardiopulmonary bypass surgery for CHD in children. The model displayed accuracy and reliability and was evaluated by discrimination and calibration analyses. The AUCs for the development and validation groups were 0.900 and 0.908, respectively, and the P-values of the calibration tests were 0.999 and 0.452 respectively. Therefore, the predicted probability of the model was consistent with the actual probability.Conclusions: Identified the independent risk factors of pulmonary infection after cardiopulmonary bypass surgery. An individualized prediction model was developed to evaluate the pulmonary infection of patients after surgery. For high-risk patients, after surgery, targeted interventions can reduce the risk of pulmonary infection. [ABSTRACT FROM AUTHOR]

Download slide Download slide OBJECTIVES Surgical repair of pectus excavatum is typically carried out immediately prior to puberty. However, at the time of surgery, some psychosocial issues, such as behavioural disorders may already have developed and the likelihood of these psychosocial disorders resolving after surgery is unclear. For this reason, some surgeons choose to perform surgical repair at an earlier age in some children. The study retrospectively compares the rate of behavioural disorders in children undergoing the Nuss procedure at 4 vs. 10 years of age. We also attempted to develop a model to predict the risk of behavioural disorders in 10 year-old patients. METHODS The current study included children receiving Nuss procedure for pectus excavatum at either 4 or 10 years of age. The presence/absence of behavioural disorder was assessed preoperatively, and in the third year, after removal of the bar. A propensity score matching (PSM) analysis was conducted to reduce the potential for confounding by baseline factors. Multivariable logistic regression was conducted to establish a model to predict the risk of behavioural disorders in the third year after the removal of the bar. The model was accessed by discrimination and calibration. A formula and a nomogram were developed based on the results. RESULTS The number of patients in each group was 45 after PSM. The rate of behavioural disorders at the baseline was significantly higher in the children undergoing Nuss procedure at 10 years of age [36% vs 20%, odds ratio (OR) 2.21, 95% confidence interval (CI) 0.85–5.72; P  = 0.157]. The rate of behavioural disorders in the third year after the removal of the bar was 36% and 18% in children undergoing surgery at 10 and 4 years of age, respectively (OR 2.55, 95% CI 0.96–6.79; P  = 0.094). The rate of persistent behavioural disorders, defined as continuing to have behavioural disorders in the third year after the removal of the bar in those with behavioural disorders at the baseline, was 88% vs 56% (OR 3.47, 95% CI 0.56–21.36; P  = 0.204). Two patients (4%) relapsed in each group. A risk prediction model by variables of gender, Haller index, pulmonary function and score of Child Behaviour Checklist at the baseline was provided. CONCLUSIONS The rate of behavioural disorders was considerably lower in children who underwent the Nuss procedure at 4 years of age than at 10 years of age. Behavioural disorders may not readily resolve after surgery. Performing surgery at an early age rather than just before puberty may be better for psychosocial development. Psychosocial aid is necessary in addition to surgery to address behavioural disorders. [ABSTRACT FROM AUTHOR]

Background: The purpose of our study was to assess the frequency of occult foreign body aspiration (FBA) and to evaluate the diagnostic difficulties and therapeutic methods for these patients., Methods: Between May 2000 and May 2020, 3557 patients with the diagnosis of FBA were treated in our department. Thirty-five patients with occult FBA were included in this study. A retrospective analysis of medical records was performed., Results: Twenty-three male patients (65.7%) and 12 female patients (34.3%) were hospitalized due to occult FBA. The average age was 3.60 years (range 9 months-12 years). Most of the patients were younger than 3 years old (n = 25, 71.4%). Coughing (n = 35, 100%) and wheezing (n = 18, 51.4%) were the main symptoms and signs. All the patients were found to have a FBA under the fiberoptic bronchoscope. The most common organic foreign bodies were peanuts (n = 10) and the most common inorganic foreign bodies were pen caps (n = 5). The extraction of foreign bodies under rigid bronchoscopy was applied successfully in 34 patients. Only one patient needed a surgical intervention., Conclusions: Occult FBA should always be considered in the differential diagnosis of chronic or recurrent respiratory diseases that are poorly explained, even in the absence of a previous history of aspiration.
