Studies on the association between pleural effusion (PE) and left ventricular assist devices (LVADs) are limited. This study aimed to examine the characteristics and the clinical impact of PE following LVAD implantation. Methods: This study is a prospective analysis of patients who underwent LVAD implantation from June 2015 to December 2022. We investigated the prognostic impact of therapeutic drainage (TD) on clinical outcomes. We also compared the characteristics and clinical outcomes between early and late PE and examined the factors related to the development of late PE. Results: A total of 71 patients was analyzed. The TD group (n=45) had a longer ward stay (days; median [interquartile range]: 31.0 [23.0–46.0] vs. 21.0 [16.0–34.0], P=0.006) and total hospital stay (47.0 [36.0–82.0] vs. 31.0 [22.0–48.0], P=0.002) compared to the no TD group (n=26). Early PE was mostly exudate, left-sided, and neutrophil-dominant even though predominance of lymphocytes was the most common finding in late PE. Patients with late PE had a higher rate of reintubation within 14 days (31.8% vs. 4.1%, P=0.004) and longer hospital stays than those without late PE (67.0 [43.0–104.0] vs. 36.0 [28.0–48.0], P<0.001). Subgroup analysis indicated that female sex, low body mass index, cardiac resynchronization therapy, and hypoalbuminemia were associated with late PE. Conclusions: Compared to patients not undergoing TD, those undergoing TD had a longer hospital stay but not a higher 90-day mortality. Patients with late PE had poor clinical outcomes. Therefore, the correction of risk factors, like hypoalbuminemia, may be required.

Purpose: The aim of this retrospective study was to evaluate the efficacy of adjuvant cisplatin-based chemotherapy in patients with locally advanced upper tract urothelial carcinoma (UTUC), administered following radical nephroureterectomy. Materials and Methods: Patients with UTUC, arising from renal pelvis or ureter, staged pT3/T4 or N+ were treated with adjuvant chemotherapy following surgery. The chemotherapy consisted of gemcitabine 1,000 mg/m2 on days 1 and 8, cisplatin 70 mg/m2 on day 1. Treatment was repeated every 3 weeks for up to 4 cycles. Endpoints included disease-free survival (DFS), metastasis-free survival (MFS), and safety. Results: Among 89 eligible patients, 85 (95.5%) completed at least 3 cycles of adjuvant chemotherapy. Chemotherapy was well tolerated, the main toxicities being mild-to-moderate gastrointestinal toxic effects and pruritus. With a median follow-up of 37 months, median DFS was 30 months (95% confidence interval, 22 to 39), and the median MFS was not reached. The 3-year DFS and MFS were 44% and 56%, respectively. Multivariate analyses revealed that the main factor associated with DFS and MFS was the lymph node involvement, whereas age, T category, grade, or the primary site of UTUC were not significantly associated with DFS or MFS. Conclusion Adjuvant cisplatin-based chemotherapy after radical surgery of pT3/T4 or N+ UTUC was feasible and may demonstrate benefits in DFS and MFS. Whether novel agents added to the chemotherapy regimen, as a concurrent combination or maintenance, impacts on survival or reduces the development of metastases remains to be studied.

Objectives: Public healthcare data have become crucial to the advancement of medicine, and recent changes in legal structure on privacy protection have expanded access to these data with pseudonymization. Recent debates on public healthcare data use by private insurance companies have shown large discrepancies in perceptions among the general public, healthcare professionals, private companies, and lawmakers. This study examined public attitudes toward the secondary use of public data, focusing on differences between public and private entities. Methods: An online survey was conducted from January 11 to 24, 2022, involving a random sample of adults between 19 and 65 of age in 17 provinces, guided by the August 2021 census. Results: The final survey analysis included 1,370 participants. Most participants were aware of health data collection (72.5%) and recent changes in legal structures (61.4%) but were reluctant to share their pseudonymized raw data (51.8%). Overall, they were favorable toward data use by public agencies but disfavored use by private entities, notably marketing and private insurance companies. Concerns were frequently noted regarding commercial use of data and data breaches. Among the respondents, 50.9% were negative about the use of public healthcare data by private insurance companies, 22.9% favored this use, and 1.9% were “very positive.” Conclusions This survey revealed a low understanding among key stakeholders regarding digital health data use, which is hindering the realization of the full potential of public healthcare data. This survey provides a basis for future policy developments and advocacy for the secondary use of health data.

This case report presents inferior alveolar nerve (IAN) repositioning as a viable approach for implant placement in the mandibular molar region, where challenges of severe alveolar bone width and height deficiencies can exist. Two patients requiring implant placement in the right mandibular molar region underwent nerve transposition and lateralization. In both cases, inadequate alveolar bone height above the IAN precluded the use of short implants. The first patient exhibited an overall low alveolar ridge from the anterior to posterior regions, with a complex relationship with adjacent implant bone level and the mental nerve, complicating vertical augmentation. In the second case, although vertical bone resorption was not severe, the high positioning of the IAN within the alveolar bone due to orthognathic surgery raised concerns regarding adequate height of the implant prosthesis. Therefore, instead of onlay bone grafting, nerve transposition and lateralization were employed for implant placement. In both cases, the follow-up results demonstrated successful osseointegration of all implants and complete recovery of postoperative numbness in the lower lip and mentum area. IAN repositioning is a valuable surgical technique that allows implant placement in severely compromised posterior mandibular regions, promoting patient comfort and successful implant placement without permanent IAN damage.

Background and Objectives: The diagnosis of hearing impairment is based on repeated audiometry, including pure tone audiometry (PTA), speech reception threshold test (SRT), and speech discrimination test (SDT). SDT results particularly show a wide discrepancy upon repeated testing, while malingering is suspected when having more than 12% difference between 3 individual SDT results. Therefore, in this study, we compared the proportion of malingering found in repeated SDT with that found in other audiometric tests and analyzed the characteristics of malingering group in order to reevaluate the current criteria of defining malingering.Subjects and Method We retrospectively assessed the audiometry results of 113 patients (226 ears) with hearing impairment. Each ear was divided into a malingering group and a true hearing loss group. The proportion of ears corresponding to each malingering criterion was compared using a chi-square test. An independent sample t-test was performed to identify the differences between the characteristics between the two groups. Results: The number of ears that met the malingering criteria were 19 (8.41%) in PTA, 15 (6.64%) in SRT, and 75 (33.19%) in SDT. There was a significant difference in the proportion of malingering between the 3 hearing test modalities (p<0.001). There was no significant difference in auditory brainstem response, mean age and sex distribution between the malingering group and the true hearing loss group. Conclusion When conducting repeated SDT, there is a risk of misdiagnosing an actual hearing loss patient as a malingering patient under the current malingering criteria. Therefore, the current criteria on SDT requires reevaluation.

Painful post-traumatic trigeminal neuropathy (PPTTN) is a distinctive facial pain syndrome characterized by facial and/or oral pain along the sensory distribution of the fifth cranial nerve with a clear history of a traumatic event. To our knowledge, PPTTN after endoscopic sinus surgery (ESS) has not been reported in the literature. We present a case of an elderly woman who experienced unilateral neuralgic pain after undergoing ESS. Following ESS of the left sphenoid sinus to remove suspicious fungus balls, the patient complained of intermittent facial pain occurring in the left periorbital and forehead area. Clinical diagnosis of PPTTN was established after a comprehensive multidisciplinary assessment. The pain disappeared completely after a 5-week medical treatment with gabapentin. Since PPTTN cases associated with ESS are extremely rare, our case demonstrates that PPTTN should be considered in the differential diagnosis of facial pain developing after ESS and can be successfully treated with medical therapy.

BACKGROUND: We evaluated change in the mandibular condyle after orthognathic surgery using cone-beam computed tomography (CBCT) in patients with facial asymmetry. METHODS: Thirty patients with skeletal class III malocclusion and mandibular prognathism or facial asymmetry were classified into two groups according to the amount of menton deviation (MD) from the facial midline on anteroposterior (AP) cephalogram: group A (asymmetry, MD ≥ 4 mm; n = 15) and group B (symmetry, MD < 4 mm; n = 15). Position and angle of condylar heads on the axial, sagittal, and coronal views were measured within 1 month preoperatively (T0) and postoperatively (T1) and 6 months (T2) postoperatively. RESULTS: On axial view, both groups showed inward rotation of condylar heads at T1, but at T2, the change was gradually removed and the condylar head returned to its original position. At T1, both groups showed no AP condylar head changes on sagittal view, although downward movement of the condylar heads occurred. Then, at T2, the condylar heads tended to return to their original position. The change in distance between the two condylar heads showed that they had moved outward in both groups, causing an increase in the width between the two heads postoperatively. Analysis of all three-dimensional changes of the condylar head positions demonstrated statistically significant changes in the three different CBCT views in group B and no statistically significant changes in group A. CONCLUSIONS: There was no significant difference between the two groups in condylar head position. Because sagittal split ramus osteotomy can be performed without significant change in symmetrical and asymmetrical cases, it can be regarded as an effective method to stabilize the condylar head position in patients with skeletal class III malocclusion and mandibular prognathism or facial asymmetry.
