Managing giant partially thrombosed intracranial aneurysms presents significant challenges due to their unfavorable natural history and the lack of standardized treatment approaches. Conventional treatments, whether open surgical or endovascular, often struggle to manage these aneurysms effectively, resulting in high recurrence rates or significant morbidity. The patient was a 62-year-old male with a symptomatic giant partially thrombosed aneurysm at the tip of the basilar artery, presenting with left-sided hemiparesis and dysarthria. Diagnostic imaging revealed a giant aneurysm with a wide-necked, canalized portion. A two-stage endovascular treatment was conducted, involving a balloon occlusion test and intraoperative monitoring for maximum patient safety. The treatment utilized stent-assisted Woven EndoBridge (WEB) embolization and serial bilateral vertebral artery trapping. The procedure successfully isolated the aneurysm and postoperative imaging confirmed the absence of recanalization, preserving the intact posterior circulation. The patient showed stable recovery and no neurological deficits during the 12-month follow-up period. This technical note demonstrates the feasibility and efficacy of strategically integrating intrasaccular flow diversion using a WEB device and flow reversal through bilateral vertebral artery trapping for treating giant partially thrombosed aneurysms.

While advances in cancer treatment have led to improved survival rates, cancer survivors are at a significant risk of developing atherosclerotic cardiovascular disease (ASCVD).This review examines the risk, diagnosis, and prevention of ASCVD in this population.Cancer survivors, especially those diagnosed with certain types, face a significantly higher risk of developing ASCVD than the general population. We introduce the “triad model” to explain this increased risk of ASCVD among cancer patients. This model includes three interconnected components: common catalysts, cancer influence, and treatment impact.The factors contributing to this model are the shared risk factors between cancer and ASCVD, such as smoking, obesity, and systemic inflammation; the direct effects of cancer on cardiovascular health through chronic systemic inflammation and endothelial damage;and the significant effects of anticancer treatments, including chemotherapy and radiation, which can worsen cardiovascular complications and hasten the progression of ASCVD.Furthermore, cancer survivors are at a higher risk of developing and dying from ASCVD, highlighting the necessity for tailored guidelines and strategies for ASCVD prevention and management in this population. The review explores the utility of diagnostic tools, such as coronary artery calcium scoring, in predicting and managing ASCVD risk. It also emphasizes the importance of prevention strategies that include regular cardiovascular monitoring and lifestyle modifications. Finally, the relationship between cancer survival and cardiovascular health highlights the importance of integrated and comprehensive care approaches.Continued research, the development of prediction models, and specific preventative strategies are essential to improve cancer survivors’ overall health outcomes.

Background/Aims: Fexuprazan, a novel potassium-competitive acid blocker, was developed for treating acid-related disorders. Pharmacokinetic and pharmacodynamic properties of fexuprazan, unlike those of proton pump inhibitors, are independent of food effect. This study aims to evaluate differences in efficacy and safety of fexuprazan in patients with erosive esophagitis (EE) according to the timing of dosing. Methods: In this multicenter, open-label noninferiority study, patients who had typical reflux symptoms with endoscopically confirmed EE were randomized 1:1 to receive fexuprazan 40 mg daily 30 minutes before or after meal. Treatment was completed after 2 weeks or 4 weeks when healing was endoscopically confirmed. The primary endpoint was the proportion of patients with healed EE confirmed by endoscopy up to week 4. Safety endpoints included treatment-emergent adverse events (TEAEs). Results: In the prior-to-meal group (n = 89) and after-meal group (n = 86), 4-week EE healing rates were 98.77% and 100.00% (difference, 0.01%; 95% CI, –0.01% to 0.04%) and 2-week EE healing rates were 95.77% and 97.14% (difference, 0.01%; 95% CI, –0.05% to 0.07%), respectively. TEAEs were 9.78% and 8.70% in the prior-to-meal group and the after-meal group, respectively. Conclusions Non-inferiority analysis revealed that taking fexuprazan after meal was non-inferior to taking fexuprazan before meals in patients with EE. The frequency of adverse events was similar between the 2 study groups. The drug is safe and effective for healing EE regardless of the timing of dosing.

The prelacrimal recess approach (PLRA) has advanced endoscopic sinonasal surgery by providing improved access to the maxillary sinus and adjacent anatomical regions while preserving critical structures such as the inferior turbinate (IT) and nasolacrimal duct (NLD). First introduced in 2013, the PLRA has become an important technique for addressing various sinonasal pathologies. This review comprehensively evaluates the advancements, applications, and outcomes associated with the PLRA. The PLRA enables superior visualization and access to regions that are traditionally difficult to reach with conventional techniques. Standardized surgical steps emphasize meticulous preservation of the NLD and IT, while technical modifications have broadened its feasibility in patients with narrow prelacrimal recesses. Applications of the PLRA span diverse pathologies, including sinonasal inverted papilloma, fungal infections, odontogenic cysts, and tumors of the lacrimal system, orbit, and skull base. Anatomical studies reveal significant variations in prelacrimal recess dimensions across populations, affecting surgical feasibility. Sex-specific differences, ethnic variations, and age-related factors are important in patient selection. Clinical outcomes from multiple investigations validate the PLRA’s efficacy in maintaining sinonasal function while achieving comprehensive lesion removal. Comparative analyses with traditional approaches underscore the PLRA’s advantages in reducing postoperative morbidity and recurrence rates. Integration of the PLRA with complementary surgical approaches further expands its therapeutic applications while maintaining favorable safety profiles. The PLRA is a safe and effective surgical method that offers favorable outcomes in disease management, symptom resolution, and anatomical preservation. With ongoing innovations and refinements, the PLRA is poised to remain a cornerstone of minimally invasive sinonasal surgery, enabling the precise and safe treatment of complex pathologies.

Background: and Purpose The Treat Stroke to Target (TST) was a randomized clinical trial involving French and Korean patients demonstrating that a lower low-density lipoprotein cholesterol (LDL-C, <70 mg/dL) target group (LT) experienced fewer cerebro-cardiovascular events than a higher target (90–110 mg/dL) group (HT). However, whether these results can be applied to Asian patients with different ischemic stroke subtypes remains unclear. Methods: Patients from 14 South Korean centers were analyzed separately. Patients with ischemic stroke or transient ischemic attack with evidence of atherosclerosis were randomized into LT and HT groups. The primary endpoint was a composite of ischemic stroke, myocardial infarction, coronary or cerebral revascularization, and cardiovascular death. Results: Among 712 enrolled patients, the mean LDL-C level was 71.0 mg/dL in 357 LT patients and 86.1 mg/dL in 355 HT patients. The primary endpoint occurred in 24 (6.7%) of LT and in 31 (8.7%) of HT group patients (adjusted hazard ratio [HR]=0.78; 95% confidence interval [CI]=0.45–1.33, P=0.353). Cardiovascular events alone occurred significantly less frequently in the LT than in the HT group (HR 0.26, 95% CI 0.09–0.80, P=0.019), whereas there were no significant differences in ischemic stroke events (HR 1.12, 95% CI 0.60–2.10, P=0.712). The benefit of LT was less apparent in patients with small vessel disease and intracranial atherosclerosis than in those with extracranial atherosclerosis. Conclusion In contrast to the French TST, the outcomes in Korean patients were neutral. Although LT was more effective in preventing cardiovascular diseases, it was not so in stroke prevention, probably attributed to the differences in stroke subtypes. Further studies are needed to elucidate the efficacy of statins and appropriate LDL-C targets in Asian patients with stroke.

This review examines the therapeutic potential of neuromodulation methods, including neurofeedback, transcranial direct current stimulation (tDCS), and transcranial magnetic stimulation (TMS), as non-pharmacological interventions for children with attentiondeficit/hyperactivity disorder (ADHD). A comprehensive review of current studies was conducted, focusing on each technique’s mechanism, application, and efficacy in managing ADHD symptoms and cognitive deficits. Studies included human participants with ADHD, evaluating changes in symptom severity and cognitive outcomes. Neurofeedback demonstrated efficacy in symptom reduction, particularly when combined with pharmacotherapy, yielding sustained improvements. tDCS showed moderate efficacy, especially in attention and impulsivity control; however, variability in protocols and pediatric response highlights the need for standardization. TMS exhibited mixed outcomes, with high-frequency TMS targeting the dorsolateral prefrontal cortex indicating potential cognitive benefits, though results were inconsistent across studies. Neuromodulation presents a promising complementary approach for ADHD treatment in children, potentially addressing limitations of pharmacotherapy. Future research should focus on optimizing stimulation parameters, increasing sample sizes, and refining methodologies to establish neuromodulation as part of standard ADHD treatment protocols.

Purpose: To report a case of infectious keratitis and endophthalmitis caused by two types of antibiotic-resistant bacteria.Case summary: A 62-year-old female patient presented to our clinic with left ocular pain for 2 weeks and was diagnosed with herpetic keratitis and anterior uveitis. At the initial presentation, slit lamp biomicroscopy revealed round stromal infiltration and edema in the paracentral part of the cornea, a 2 × 2-mm epithelial defect, and hypopyon. Ocular ultrasonography showed vitreous opacities. She was empirically treated with topical 0.5% moxifloxacin, 2% tobramycin, and 5% ceftazidime administered hourly. Intravitreal vancomycin/ceftazidime administration was performed on days 2 and 7 following treatment. Corneal culture revealed extended-spectrum β-lactamase-producing Klebsiella pneumoniae and methicillin-resistant Staphylococcus aureus on day 4 after treatment. Consequently, 2% tobramycin was replaced with 1% vancomycin. The corneal lesion gradually improved and healed completely with a residual corneal opacity at 4 weeks after treatment. Conclusions Polymicrobial bacterial keratitis caused by antibiotic-resistant bacteria represents a treatment challenge. Therefore, culture is essential to obtain microbiological evidence and guide appropriate antibiotic selection.

Background: Complete revascularization has demonstrated better outcomes in patients with acute myocardial infarction (AMI) and multivessel disease. However, in the case of left main (LM) culprit lesion AMI with multivessel disease, there is limited evidence to suggest that complete revascularization is better. Methods: We reviewed 16,831 patients in the Korea Acute Myocardial Infarction Registry who were treated from July 2016 to June 2020, and 399 patients were enrolled with LM culprit lesion AMI treated with percutaneous coronary intervention. We categorized the patients as those treated with complete revascularization (n=295) or incomplete revascularization (n=104). The study endpoint was major adverse cardiac and cerebrovascular events (MACCE), a composite of all-cause death, myocardial infarction, ischemia-driven revascularization, stent thrombosis, and stroke. We performed propensity score matching (PSM) and analyzed the incidence of MACCE at 1 year. Results: After PSM, the two groups were well balanced. There was no significant difference between the two groups in MACCE at 1 year (12.1% vs. 15.2%; hazard ratio, 1.28; 95% confidence interval, 0.60–2.74; p=0.524) after PSM. The components of MACCE and major bleeding were also not significantly different. Conclusion There was no significant difference in clinical outcomes between the groups treated with complete or incomplete revascularization for LM culprit lesion AMI with multivessel disease.

There are various methods for reconstructing defects caused by Mohs micrographic surgery (MMS). However, there are limits to the reconstruction methods that can be used if the defect is large. An 85-year-old woman presented with a 2.4×2.2 cm hyperkeratotic plaque on her right temple for 2 years. A skin biopsy was performed for a diagnosis. Histopathology confirmed squamous cell carcinoma, and MMS was performed to completely remove the tumor. A total of three MMS stages were performed intraoperatively to confirm margin clear, resulting in a skin defect measuring 5.0×4.5 cm. To reconstruct the large defect, a splitted full thickness skin graft was performed, taking into account the site, size, and function of the defect. Each skin graft was harvested from the submental area and a tie-over bolster dressing was applied to the recipient site. To date, the surgical site has remained free of surgical complications or tumor recurrence.
