Objectives: The landscape of work environments has undergone rapid transformation in the wake of the COVID-19 pandemic. This study aims to identify oral health issues among mobile platform workers, analyze the risk factors within their working environment, and promote their oral health. Methods: A purposive sampling approach was employed to select fifteen participants, including replacement drivers, delivery drivers, and delivery couriers/messengers operating within Seoul’s mobile platform workforce. In-depth interviews were conducted between August and November 2023, with all sessions recorded and transcribed. Utilizing grounded theory methodology, data analysis progressed through stages of open coding, axial coding, and selective coding, ultimately leading to the construction of a paradigm model. Results: The majority of participants were male (93.3%), with an average age of 58.7 years. The paradigm model revealed low tooth brushing rates among mobile platform workers. This phenomenon was attributed to a poor brushing environment and a lack of willingness to brush, with the related context being the poor working environment. Intervention conditions included support for tooth brushing, oral health education, and oral examinations. Implementing an action-interaction strategy, which involves problem-solving pathways and a strong motivation to improve, resulted in improved tooth brushing rates. Conclusions To promote the oral health of mobile platform workers, it is essential to improve the environment for tooth brushing, particularly by increasing the availability of restrooms and related facilities as brushing spaces. Additionally, It is necessary to develop oral health policies and implement interventions based on an understanding of the working environment of mobile platform workers.

Arytenoid dislocation is an unusual complication of endotracheal intubation. We reported a case of a 48-year-old female with arytenoid dislocation after uneventful endotracheal intubation, which was successfully treated with arytenoid reduction. The patient complained of persistent hoarseness until the fourth day after an uneventful gynecologic surgery under general anesthesia. On laryngoscopic examination, paralyzed left vocal cord with minimal arytenoid movement was observed. An anteromedial dislocation of the left arytenoid cartilage was suspected and surgical reduction was performed by the laryngologist. The hoarseness was immediately resolved after surgical intervention. Anesthesiologists should be careful not to cause laryngeal trauma in anesthetized patients. In addition, early diagnosis and prompt surgical reduction are essential for a better prognosis for arytenoid dislocation.

Background: Swallowing function deterioration is a common problem experienced by older adults worldwide. Many studies have been conducted to improve swallowing function in older adults; however, due to differences in intervention methods and study designs, it is difficult to draw a common conclusion. This study aimed to analyze trends and intervention methods in studies of swallowing function intervention for older adults conducted from 2010 to 2022, to establish a systematic approach for developing interventions to improve swallowing function in older adults and to provide evidence for this approach. Methods: Literature research was conducted for studies published between 2010 and 2022 that applied to swallow function interventions to adults aged 60 years or older. Databases including PubMed, Medline, RISS, Science On, KISS, and KCI were used. From a total of 1,164 articles searched using keywords, 20 articles were selected for final analysis. Results: The number of published articles steadily increased over time, and the intervention period was most commonly 6 or 8 weeks. The types of interventions included focused exercises to improve oral muscle strength in 12 articles and programs incorporating education, practice, and expert management in 8 articles. Among the focused exercises, tongue-strengthening exercises were most common in 4 articles. The evaluation variables for intervention effects were muscle strength evaluation, oral function evaluation, quality of life, and oral health and hygiene status. Muscle strength and oral function evaluations were statistically significant in focused exercise interventions, while the quality of life and oral health and hygiene status was significant in program interventions. Conclusion This literature review is meaningful as a study that can be used to select the intervention period and program contents when planning an elderly swallowing intervention program.

We experienced a case of aneurysm of the sinus of Valsalva dissecting into the ventricular dseptum. This dissection was induced by paravalvular leakage after aortic and mitral valve replacement. This 37-year-old male was admitted via emergency room due to progressive dyspnea. He had undergone aortic valve replacement(carbomedic(R) 23 mm) and mitral valve replacement(carbomedic(R) 31 mm) due to aortic regurgitation and mitral regurgitation about 6 years prior to admission and followed up regularly. The diagnosis was made by transthoracic and transesophageal echocardiography and reconfirmed by root aortography. The inlet of the ventricular septal aneurysmal sac was repaired by one layer suture with 3-0 prolene of the endocardium, epicardium and homograft muscle shoulder altogether. Postoperative course was uneventful and the patient was discharged on the 11th postoperative day.

This study was performed to evaluate the efficacy and toxicity of low-dose paclitaxel/cisplatin chemotherapy in patients with metastatic or recurrent gastric cancer that had failed 5-fluorouracil/platinum-based chemotherapy. Thirty-two patients with documented progression on or within 6 months after discontinuing 5-fluorouracil/platinum-based chemotherapy were enrolled. As a second-line treatment, paclitaxel (145 mg/m2) and cisplatin (60 mg/m2) was administered on day 1 every 3 weeks. Among 32 patients enrolled, 8 (25%) responded partially to paclitaxel/cisplatin, 8 (25%) had stable disease, and 14 (44%) had progressive disease. Two patients (6%) were not evaluable. The median time to progression (TTP) and overall survival for all patients were 2.9 months and 9.1 months, respectively. The most common hematologic toxicity was anemia (47%). Grade 3 neutropenia developed in three patients (9%), but no other grade 3/4 hematologic toxicity occurred. The most common non-hematologic toxicities were emesis (31%) and peripheral neuropathy (38%). Three cases (9%) of grade 3/4 emesis and 2 cases (6%) of grade 3 peripheral neuropathy developed. In conclusion, low-dose paclitaxel and cisplatin chemotherapy showed moderate activity with favorable toxicity profiles. However, relatively short TTP of this regimen warrants the development of more effective paclitaxel-based regimens other than combination with cisplatin in these patients as second-line therapies.
