UNASSIGNED: Hyoid bone movement is potentially related to aspiration risk in post-stroke dysphagia (PSD) patients but is difficult to assess quantitatively. This study aimed to measure the distance of hyoid bone movement more efficiently and accurately using a deep learning model and determine the clinical usefulness of the model in PSD patients.
UNASSIGNED: This study included 85 patients with PSD within 6 months from onset. Patients were grouped into an aspiration group (n = 35) and a non-aspiration group (n = 50) according to the results of a videofluoroscopic swallowing study. Hyoid bone movement was tracked using a deep learning model constructed with the BiFPN-U-Net(T) architecture. The maximum distance of hyoid bone movement was measured horizontally (H max), vertically (V max), and diagonally (D max).
UNASSIGNED: Compared with the non-aspiration group, the aspiration group showed significant decreases in hyoid bone movement in all directions. The area under the curve of V max was highest at 0.715 with a sensitivity of 0.680 and specificity of 0.743. The V max cutoff value for predicting aspiration risk was 1.61 cm. The success of oral feeding at the time of discharge was significantly more frequent when hyoid movement was equal to or larger than the cutoff value although no significant relationship was found between hyoid movement and other clinical characteristics.
UNASSIGNED: Hyoid bone movement of PSD patients can be measured quantitatively and efficiently using a deep learning model. Deep learning model-based analysis of hyoid bone movement seems to be useful for predicting aspiration risk and the possibility of resuming oral feeding.

BACKGROUND Foreign body aspiration (FBA) is a common and serious problem in childhood that requires early recognition and treatment. Common complications include asphyxia, hemorrhage, infection, and pneumothorax. In severe cases of foreign body obstruction, death can result from asphyxia. We report an interesting case in which a forgotten cotton ball was inhaled into the lungs. CASE REPORT A 5-year-old boy presented to the local hospital with coughing for 6 days and fever for 4 days, without any information of foreign body aspiration upon admission. Laboratory findings indicated an elevated white blood cell; therefore, cefprozil was given as anti-infective treatment. However, the child\'s condition did not improve. A computed tomography scan showed left pulmonary atelectasis. Considering that the child\'s condition was serious, he was referred to our hospital for diagnosis and treatment. After referral, auscultation revealed decreased breath sounds over the left lung. After multidisciplinary discussion, combined with the results of auxiliary examination, the possibility of a foreign body was considered. He underwent rigid bronchoscopy, which confirmed a yellow-white foreign body in the left main bronchus that was later verified as a cotton ball. The operation was very successful. Eventually, his condition improved and he was discharged, without additional complications. CONCLUSIONS For children with unclear history of foreign body aspiration, bronchoscopy is recommended if there is recurrent pulmonary infection, low auscultation breath sounds, or abnormal imaging. The choice of surgical method depends on the location and type of foreign body and the experience of the surgeon, which is also very important.

Foreign body aspiration (FBA) is a serious preventable pediatric health problem and one of the main causes of accidental death in children. Although unusual in adults, it is often overlooked as a cause of airway obstruction with serious consequences. This study assessed awareness and previous FBA experiences in the Asir community, Kingdom of Saudi Arabia. Using validated questionnaire, an annonymous online survey was conducted among 870 people aged 18 years and above. The questionnaire was used to collect data about the personal and sociodemographic characteristics of the respondents, as well as their experiences with FBA, and participants\' knowledge and perceived seriousness of FBA. The level of knowledge was deemed good if the score ranged between 60% and 100%, and bad if the score fell below 60%The level of knowledge was deemed good if the score ranged between 60% and 100%, and bad if the score fell below 60%. The majority of the participants (79.7%) were females, 48.1% were aged 18 to 30 years, 72.9% had university degree, 30.6% were students, 26.9% worked in the educational sector, 43.6% reported monthly income of <5000 Saudi Riyals and 19.8% of them identified themselves as healthcarepractitioners. Although the community experience with FBA was considerably high (70.6%) among the study participants, their awareness levels about FBA were deficient. Only 24.7% of the respondents had good knowledge of FBA. Older age, being a health practitioner, and perceiving FBA as a serious incident were significantly associated with good knowledge (P < .001). The findings of this study indicate an urgent need to raise community awareness of FBA. To reduce FBA morbidity and mortality, health education efforts in community and healthcare settings are required to educate people about the seriousness and importance of early diagnosis and management of the condition.

UNASSIGNED: Ingestion of gasoline can cause severe pulmonary and gastrointestinal complications. Computed tomography may reveal characteristic findings.
UNASSIGNED: A 61-year-old man had gastrointestinal symptoms, and subsequently developed respiratory distress and altered mental status after ingesting approximately 150 mL of gasoline.
UNASSIGNED: Abdominal computed tomography revealed a characteristic three-layered appearance of intestinal contents, likely representing intestinal fluid, ingested gasoline, and gas. Chest computed tomography showed bilateral pulmonary infiltrates consistent with pneumonitis.
UNASSIGNED: Recognition of the characteristic three-layered appearance of the intestinal contents on abdominal computed tomography might aid in the diagnosis of gasoline ingestion.

For the elderly, the risks associated with pulmonary aspiration are significant, and can severely impact their quality of life. Therefore, the management of pulmonary aspiration risk is crucial in promoting healthy aging, an aspect often overlooked in self-health management for the elderly. To enhance self-management of pulmonary aspiration risk among the elderly, we have organized a multidisciplinary team to develop an intelligent risk hierarchical management system on pulmonary aspiration for the elderly. This system tailors the assessment with different questionnaires based on the elderly individual\'s environment. Additionally, it utilizes elderly-friendly formats such as pictures, videos and animations, making it easier for seniors to comprehend the occurrence and hazards of pulmonary aspiration. This enables them to proactively take preventive measures to manage the risk, thus achieving self-management of pulmonary aspiration risk.

OBJECTIVE: Tracheobronchial foreign body aspiration is a common pediatric emergency and a leading cause of accidental deaths in children. The diagnosis remains sometimes difficult even with physical examination, medical history, and basic X-rays. This challenge necessitates the performance of endoscopy under general anesthesia, regardless of the potential for serious complications. The benefit of strategies like expiratory chest X-rays to reduce unnecessary endoscopies remains uncertain. We evaluated the effectiveness of expiratory chest X-rays in detecting airway foreign bodies to potentially reduce the need for endoscopies.
METHODS: We retrospectively studied children with suspected foreign body aspiration who had X-ray and endoscopy.
RESULTS: A total of 70 children were included in the study. Out of these, 19 cases (27.1 %) showed pathological findings on standard chest X-rays. However, when expiratory chest X-rays were added, the number of pathological radiographies increased to 37 cases (52.9 %). Out of the 36 foreign bodies that were present, only 2 were not detected. Furthermore, 3 chest X-rays displayed pathological results, while the endoscopies indicated normal findings. Consequently, the overall sensitivity, specificity, positive predictive value, and negative predictive value stood at 94.4 %, 91.1 %, 91.9 %, and 93.9 % respectively.
CONCLUSIONS: The remarkable sensitivity of expiratory chest radiography can eliminate the need for unnecessary endoscopy, but it should be limited to centers lacking access to MDCT. The performance of endoscopy should only be considered when persistent clinical symptoms are observed during auscultation.

OBJECTIVE: To evaluate the effectiveness of coordinated endoscopy with otolaryngology, pulmonology, and gastroenterology in diagnosing and managing chronic aspiration in pediatric patients.
METHODS: We reviewed our REDCap Pediatric Aerodigestive Database for patients with chronic aspiration who underwent coordinated endoscopy between January 2013 and July 2023. Patient demographics, comorbidities, operative findings, interventions, and outcomes were reviewed.
RESULTS: Forty-nine patients were identified with a diagnosis of aspiration. Their mean (SD) age was 28 (36) months (range 1.2-163 months) with more than half of the patients younger than 24 months. The most common findings noted on combined endoscopies were laryngeal cleft (n = 30), positive bacterial culture (n = 18), positive viral PCR (n = 17), and active reflux-induced esophagitis/gastritis (n = 9). Patients with a positive bacterial culture were associated with a history of recurrent pneumonia (p = 0.009). There were no other significant associations between endoscopy findings and patient demographics, co-morbidities, or symptoms. Twenty-five (51 %) had multiple abnormalities identified by at least 2 different specialists at the time of endoscopy and 6 patients (12 %) had abnormalities across all three specialists.
CONCLUSIONS: Coordinated endoscopy should be considered in pediatric patients presenting with aspiration on MBS or non-specific symptoms suggestive for chronic aspiration for comprehensive diagnosis and management.

Aspiration detected in the fiberoptic endoscopy evaluation of swallowing (FEES) has been inconsistently associated with pneumonia, with no evidence of the risk of pneumonia from other alterations in swallowing safety detected in FEES. We conducted a dynamic, ambidirectional cohort study involving 148 subjects at risk of dysphagia in a tertiary university hospital. Our aim was to determine the risk of pneumonia attributed to alterations in swallowing safety detected during FEES. We used multivariate negative binomial regression models to adjust for potential confounders. The incidence density rate (IR) of pneumonia in patients with tracheal aspiration of any consistency was 26.6/100 people-years (RR 7.25; 95% CI: 3.50-14.98; P < 0.001). The IR was 19.7/100 people-years (RR 7.85; 95% CI: 3.34-18.47; P < 0.001) in those with laryngeal penetration of any consistency and 18.1/100 people-years (RR 6.24; 95% CI: 2.58-15.09; P < 0.001) in those with pharyngeal residue of any consistency. When adjusted for aspiration, the association of residue and penetration with pneumonia disappeared, suggesting that their risk of pneumonia is dependent on the presence of aspiration and that only aspiration is independently associated with pneumonia. This increased risk of pneumonia was significant in uni- and multivariate negative binomial regression models. We found an independently increased risk of pneumonia among patients with dysphagia and aspiration detected during FEES. Alterations in the oral and pharyngeal phases of swallowing, without aspiration, did not increase the risk of pneumonia.

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.
