    Abstract Aim: To describe the results of laparoscopic surgery and D3 lymph node dissection combined with adjuvant chemotherapy (ACT) for the treatment of advanced-stage right colon cancer (stages II and III).
    Methods: A total of 172 right colon cancer patients (with tumour, node, and metastasis (TNM) stage II and III; mean age of 59.30±14.27 years; 58.1% male, 41.9% female) who had undergone complete mesocolic excision (CME) with D3 lymph node dissection at Nguyen Tri Phuong Hospital, Ho Chi Minh City, Vietnam, were included in this study. They were divided into two groups: group 1 (n=34) without ACT and group 2 (n=138) with ACT. We collected clinical and laboratory data twice (before and after one year of performing laparoscopic surgery). Rates of recurrence and mortality were obtained during a five-year follow-up.
    Results: After one year of surgery, the rate of anemia and the increase in serum carcinoembryonic antigen (CEA) levels in group 1 were significantly higher than those in group 2 (p<0.001). After five years of follow-up, the recurrence rate was 11.6% (that of group 1 was 41.2%, which is higher than that of group 2, i.e., 4.3%; p<0.001), and the mortality rate was 8.7% (that of group 1 was 32.4%, which is higher than that of group 2, i.e., 2.9%; p<0.001). Preoperative serum CEA levels were predictive of recurrence and mortality, with an area under the curve (AUC) of 0.729 and 0.805, respectively (p<0.001).
    Conclusions: Laparoscopic CME surgery and D3 lymph node dissection combined with ACT reduced the five-year recurrence and mortality rates for advanced-stage right colon cancer patients.

    Abstract Cisplatin, a chemotherapeutic medication, remains in the cochlea indefinitely, causing permanent hearing loss. Mannitol, a diuretic medication, has been shown to increase the permeability of the blood labyrinth barrier (BLB). We hypothesize that mannitol increases the permeability of the BLB and therefore increases the rate of entry and egression of cisplatin and entry of otoprotective agents. Rats treated with cisplatin (t = 0) were given mannitol at either t = 0, t = 6 or t = 0,6 h. Another group of rats were treated with cisplatin with mannitol at 0 h and NAC/STS with and without mannitol at 6 h. Concurrent mannitol (t = 0) transiently increased cisplatin entry into the inner ear and exacerbated cisplatin-induced hearing loss. Delayed mannitol (t = 6) did not significantly increase cisplatin entry into the inner ear and preserved inner ear functionality and structure. Additional-delayed mannitol (t = 0,6) showed that the 2nd dose of mannitol prevented exacerbation of cisplatin with mannitol-induced hearing loss. A combination of delayed NAC/STS with mannitol (t = 6) was better than NAC/STS (t = 6) alone at providing partial to full protection against cisplatin with mannitol-induced hearing loss. In conclusion, mannitol injections at t = 6 h reduced cisplatin ototoxicity (instead of exacerbating cisplatin ototoxicity at t = 0 h), and it enhanced the otoprotective efficacy of antioxidants. This may provide an important therapeutic strategy to prevent cisplatin-induced hearing loss, a direct implication in protection against hearing loss in cisplatin chemotherapy.

    Abstract Objective: To report a novel technique in Balloon Dilation of Eustachian Tube (BDET) using an endovascular balloon (EVB), in a prospective cohort. The results are compared with reported outcomes using standard balloons.
    Methods: Demographic information and clinical parameters were collected prospectively fora series of patients with obstructive eustachian tube dysfunction (OETD). Balloon dilation Eustachian tuboplasty was performed under local anesthesia in a tertiary referral center, using the EVB. Systematic literature review was used for comparison, using Medline via "PubMed", "Embase", and "Web of Science".
    Results: Eight OETD candidates (12 ears) were enrolled; 5 males and 3 females. Average age was 48 (range -23 to 63) years. The most common presenting symptom was aural fullness (9/12), followed by ear pressure (7/12), hearing loss (5/12) and tinnitus (4/12). Otoscopically, tympanic membrane retraction was evident in 10/12 ears, the majority of which was class II-Sade classification. Pre-operative tympanogram was type B and C in 7 and 5 ears, respectively. All BDETs were performed without complications. Post-operative tympanometry was A in 8/12 ears. Post-operatively, Eustachian Tube Dysfunction Questionnaire-7 results reduced to within normal limits (average score ≤3) in 11/12 ears (
    Conclusion: BDET using an EVB is a safe and effective option for OETD. It is well tolerated under local anesthesia in properly selected individuals. The reduced procedural cost may be an important factor in certain healthcare jurisdictions.

    Abstract Objective: To investigate the impact of sound exposure, with the resultant windows vibration on perilymphatic concentrations following intratympanic (IT) dexamethasone and gentamicin in an animal model.
    Study design: Animal model blinded study.
    Setting: Animal facility of a tertiary medical center.
    Methods: Bilateral IT dexamethasone or gentamicin was applied to 15 tested rats. Following injections, each rat was exposed for 3 minutes to free field 30 dB sound pressure level (SPL), 512 vHz noise, with 1 external auditory canal plugged (contralateral control). Following noise exposure, perilymph was obtained from both ears. Drug concentrations were measured using ultrahigh-performance liquid chromatography-mass spectrometer.
    Results: For dexamethasone, the average (±SD) perilymphatic steroidal concentration was 0.417 µg/mL (±0.549) in the control ears versus 0.487 µg/mL (±0.636) in the sound-exposed ears (P = .008). The average (±SD) gentamicin perilymphatic concentration was 8.628 µg/mL (±2.549) in the sound-exposed ears, compared to 4.930 µg/mL (±0.668) in the contralateral control (nonsound exposed) ears. Sound exposure promoted steroidal and gentamicin diffusion to the inner ear by an averaged (±SD) factor of 1.431 and 1.730 (±0.291 and 0.339), respectively.
    Conclusion: Low-intensity noise (30 dB SPL) was found to enhance dexamethasone phosphate and gentamicin diffusion to the inner ear (by an averaged factor of ∼1.4 and 1.7, respectively) in a murine model.

    Abstract Background: Obstructive eustachian tube dysfunction is a common pathology, generally accepted as the underlying cause for chronic ear diseases. Eustachian tube dilation has shown promising results in randomized controlled trials, but is a costly procedure. The aim of the current study was to assess the feasibility of transnasal balloon dilatation of the eustachian tube with an endovascular balloon in the context of ease of use, maneuverability, and safety.
    Methods: Clinical pilot study carried out at a university tertiary care facility. In total, twelve patients, were included over a period of 6 months. All patients underwent tympanoplasty or tympanomastoidectomy surgeries. Eustachian tube dilation was carried out transnasal using an endovascular balloon. A computed tomography was carried out after surgery to assess for any potential damages and compared to preoperative imaging studies. Postoperative endoscopy was performed intraoperatively and at follow up to assess for any potential damages.
    Results: All eustachian tube dilations were carried out successfully. No severe adverse events were noted during the procedure, in the postoperative period, or on imaging studies. Minor adverse events such as mild intraoperative bleeding was managed in a routine fashion.
    Conclusions: Balloon dilation of the eustachian tube with the endovascular balloon was feasible and safe in all cases. It is likely a more cost-effective alternative to commercially available balloons with similar designs and specifications. Trial registration The study was registered at clinicaltrials.gov; NCT04809753, initial release February 24th, 2021.

    Abstract Exact placement of bone conduction implants requires avoidance of critical structures. Existing guidance technologies for intraoperative placement have lacked widespread adoption given accessibility challenges and significant cognitive loading. The purpose of this study is to examine the application of augmented reality (AR) guided surgery on accuracy, duration, and ease on bone conduction implantation. Five surgeons surgically implanted two different types of conduction implants on cadaveric specimens with and without AR projection. Pre- and postoperative computer tomography scans were superimposed to calculate centre-to-centre distances and angular accuracies. Wilcoxon signed-rank testing was used to compare centre-to-centre (C-C) and angular accuracies between the control and experimental arms. Additionally, projection accuracy was derived from the distance between the bony fiducials and the projected fiducials using image guidance coordinates. Both operative time (4.3 ± 1.2 min. vs. 6.6 ± 3.5 min., p = 0.030) and centre-to-centre distances surgery (1.9 ± 1.6 mm vs. 9.0 ± 5.3 mm, p < 0.001) were significantly less in augmented reality guided surgery. The difference in angular accuracy, however, was not significantly different. The overall average distance between the bony fiducial markings and the AR projected fiducials was 1.7 ± 0.6 mm. With direct intraoperative reference, AR-guided surgery enhances bone conduction implant placement while reduces operative time when compared to conventional surgical planning.

    Abstract Background: Within otologic surgery, a paucity of well-controlled studies assessing the use of systemic antibiotic to reduce surgical site infections exists. Moreover, discrepancies in wound classification of procedures challenge consensus in antimicrobial prescribing patterns. We sought to compare surgeons from two different health systems to examine how surgeons' prescribing habits compared to practice guidelines for numerous otologic procedures.
    Methods: An online questionnaire was distributed to 33 Canadian and 32 Austrian surgeons who regularly perform otologic surgery. Current systemic antibiotic prescribing habits for cochlear implantation, cholesteatoma surgery, stapes surgery, and tympanoplasty ± ossiculoplasty were collected.
    Results: Eighteen of 33 (54.5%) Canadian surgeons provided responses, while 18 of 32 (56.3%) of Austrian surgeons answered. Clear consistency with clinical practice guidelines exists for pre-operative antibiotics use in cochlear implant surgery and infected cholesteatoma surgery. However, for stapes surgery and tympanoplasty ± ossiculoplasty, consensus is lacking for both pre- and post-operative antibiotic prescribing habits. Notable differences between the two countries include post-operative antibiotics for cochlear implant surgery (Austria: 36.4%, Canada: 71.4%) and uninfected cholesteatoma surgery (Austria: 33.3%, Canada: 77.8%). Across all procedures, both induction and post-operative antibiotic administration was not significantly associated with surgeon seniority when stratified by five-year increments.
    Conclusion: The lack of consensus among each country's otologic surgeons underscores the uncertainty in wound classification and thus, adherence to clinical practice guidelines.

    Abstract Purpose: Patients with end-stage renal failure are susceptible to dry eye disease. This study explores the relationship between dry eye disease and influence factors.
    Patients and methods: The control group consisted of 57 healthy subjects who were kidney donors. They were of the same age and sex as the kidney transplant recipients. The outcome variable was the dry eye condition of the participants. The Schirmer test confirmed dry eye disease, TBUT (breakup time test), and the Eye Surface Disease Index (OSDI) questionnaire, using linear regression to evaluate the association.
    Results: The total number of subjects was 146 (89 kidney recipients and 57 kidney donors). When univariate analysis found the level of visual acuity, the age group involved was statistically significant, while the other factors were not statistically significant. In multivariable logistic regression analysis, age (odds ratio: 2.8, p<0.05), smoking history (odd ratio: 0.1, p<0.05), corneal conjunctival calcification (odd ratio: 0.2, p<0.05); central corneal thickness (odd ratio: 1.02, p<0.05) is considered to be an influence factor for disease progression.
    Conclusion: Age group, smoking history, corneal central thickness, and conjunctival calcification are factors for dry eye disease in patients preparing to receive a kidney. These results reinforce the evidence for multifactorial dry eye disease in patients with renal impairment.

    Abstract Introduction Intracranial atherosclerotic disease (ICAD) has been identified as a major cause of acute basilar artery occlusion (BAO).This study compared the characteristics and treatment outcomes in acute BAO patients with and without ICAD. Methods A prospective cohort study was conducted at 115 People's Hospital, Ho Chi Minh city, Vietnam from August 2021 to June 2023. Patients with acute BAO who underwent endovascular treatment within 24 hours from symptom onset were included (thrombectomy alone or bridging with intravenous alteplase). The baseline characteristics and outcomes were analyzed and compared between patients with and without ICAD. Good functional outcome was defined as mRS ≤ 3 at 90 days. Results Among the 208 patients enrolled, 112 (53.8%) patients were categorized in the ICAD group, and 96 (46.2%) in the non-ICAD group. Occlusion in the proximal segment of the basilar artery was more common in patients with ICAD (55.4% vs 21.9%, p < 0.001), whereas the distal segment was the most common location in the non-ICAD group (58.3% vs 10.7%, p < 0.001). Patients in the ICAD group were more likely to undergo treatment in the late window, with a higher mean onset-to-treatment time compared to the non-ICAD group (11.6 vs. 9.5 hours, p=0.01). In multivariable logistic regression analysis, distal segment basilar artery occlusion was negatively associated with ICAD (aOR 0.13, 95% CI 0.05 - 0.32, p < 0.001), while dyslipidemia showed a positive association (aOR 2.44, 95% CI 1.15 - 5.17, p = 0.02).There was a higher rate for rescue stenting in the ICAD compared to non-ICAD group (15.2% vs. 0%, p<0.001). However, no significant differences were found between the two groups in terms of good outcome (45.5% vs. 44.8%, p = 0.91), symptomatic hemorrhage rates (4.5% vs. 8.3%, p = 0.25), and mortality (42% vs. 50%, p = 0.25). Conclusion ICAD was a common etiology in patients with BAO. The location segment of basilar artery occlusion and dyslipidemia were associated with ICAD in patients with BAO. There was no difference in 90-day outcomes between BAO patients with and without ICAD undergoing endovascular therapy.

    Abstract Objective: To (i) demonstrate the utility of geographically weighted Poisson regression (GWPR) in describing geographical patterns of adult cochlear implant (CI) incidence in relation to sociodemographic factors in a publicly funded healthcare system, and (ii) compare Poisson regression and GWPR to fit the aforementioned relationship.
    Study design: Retrospective study of provincial CI Program database.
    Setting: Academic hospital.
    Patients: Adults 18 years or older who received a CI from 2020 to 2021.
    Interventions: Cochlear implant.
    Main outcome measures: CI incidence based on income level, education attainment, age at implantation, and distance from center, and spatial autocorrelation across census metropolitan areas.
    Results: Adult CI incidence varied spatially across Ontario (Moran's I = 0.04, p < 0.05). Poisson regression demonstrated positive associations between implantation and lower income level (coefficient = 0.0284, p < 0.05) and younger age (coefficient = 0.1075, p < 0.01), and a negative association with distance to CI center (coefficient = -0.0060, p < 0.01). Spatial autocorrelation was significant in Poisson model (Moran's I = 0.13, p < 0.05). GWPR accounted for spatial differences (Moran's I = 0.24, p < 0.690), and similar associations to Poisson were observed. GWPR further identified clusters of implantation in South Central census metropolitan areas with higher education attainment.
    Conclusions: Adult CI incidence demonstrated a nonstationary relationship between implantation and the studied sociodemographic factors. GWPR performed better than Poisson regression in accounting for these local spatial variations. These results support the development of targeted interventions to improve access and utilization to CIs in a publicly funded healthcare system.
