Background and Objectives: This study aimed to comprehensively assess the factors influencing hearing ability in patients with vestibular schwannoma, focusing on tumor size, location, primary complaint, and contralateral hearing threshold.Subjects and Method This was a retrospective analysis of 50 patients diagnosed with vestibular schwannoma by magnetic resonance imaging (MRI) at Nowon Eulji Medical Center. Tumor size and location were evaluated using a 3-T MRI system, and pure-tone threshold and speech discrimination were retrieved. To investigate the relationship between tumor size and hearing, we conducted a multiple regression analysis with several variables, including tumor size, tumor location, patient age, and gender. Results: When patients were categorized into groups according to their primary complaint at initial presentation, no significant differences were observed in pure tone thresholds but different speech discrimination were detected among the groups. When patients were classified according to the tumor location, the extrameatal group exhibited lower pure-tone thresholds and higher speech discrimination scores than the intrameatal group. Multiple regression analysis indicated that differences in pure tone thresholds and speech discrimination scores between affected and unaffected sides were more pronounced in cases with smaller tumor sizes and extrameatal tumor locations, emphasizing the greater impact of location over size. Conclusion Using both tumor size and location, it is possible to predict the differences in pure-tone thresholds and speech discrimination between the affected and unaffected sides. Extrameatal invasion of the tumor appears to be the most important factor among them.

Various strains can be found in emphysematous prostatic abscesses (EPAs), but the most frequent causative organism is Klebsiella pneumoniae . Hypervirulent K. pneumoniae can disseminate to distant sites by forming a muco-polysaccharide network outside the capsule. Here, we present the first case of K. pneumoniae in an EPA accompanied by a spinal cord infarction. A 65-year-old man was referred to our hospital due to sudden-onset paraplegia after a 5-day history of fever, myalgia, and voiding difficulty. Abdominal computed tomography revealed a collection of air pockets in the prostate, and diffusion-weighted magnetic resonance imaging showed high signal intensity in the thoracic spinal cord. The patient was initially treated with antibiotics and surgical drainage. On the third hospital day, therapeutic heparin was added after discussion with a neurologist. The patient had no inflammatory symptoms, experienced some improvement in paraplegia, and was discharged on the 14th hospital day. This study adhered to the case report guidelines.

Objective: This study compared the status of chronic diseases among immigrants and the Korean population. Methods: This study was conducted on 153 immigrants living in Gwangju Metropolitan City in 2022.For comparison, 459 Koreans were selected using the 2021 Korea National Health and Nutrition Examination Survey (KNHANES). A survey was conducted on the management status of hypertension, diabetes, and hyperlipidemia using a questionnaire. Results: Immigrants were significantly more likely to have hypertension (50.3% vs. 24.2%, p<0.001) and diabetes (19.0% vs. 11.5%, p=0.002) than Koreans. In awareness, immigrants had significantly lower rates of hypertension (57.1% vs. 73.0%, p=0.031) and hyperlipidemia (immigrants 25.4% vs. 44.5%, p=0.006). In treatment rates, immigrants had significantly lower rates of hypertension (40.3% vs. 69.4%, <0.001) and hyperlipidemia (17.9% vs. 39.6%, p=0.003). In control rates, immigrants had significantly lower rates of hypertension (18.2% vs. 62.2%, <0.001) than Koreans. Conclusions Chronic diseases are common among immigrants, but awareness, treatment, and control rates are low, so education and prevention policies are critical to improving immigrants’ access to medical care and raising awareness.
