Introduction: The primary issue following lumbar
discectomy for disc herniation is the risk of reherniation in
the post-operative period. Many surgical techniques have
been proposed to treat disc reherniation, however, the
optimal one remains variable. This meta-analysis aimed to
investigate the prevalence of symptomatic reherniation after
using a Bone-anchored annular closure device following
lumbar discectomy and the contributing factors.
Materials and methods: Identification of published
literature was performed on PubMed, Google Scholar,
Scopus, and Web of Science databases. Studies published
until 14 February 2024 reported the prevalence of
symptomatic reherniation after using a Bone-anchored
annular closure device following lumbar discectomy and the
associated contributing factors. A random effects model was
used to conduct Bayesian frequentist network meta-analysis
and pair-wise meta-analysis, with the assessment based on
standardised mean difference (SMD) and 95% confidence
interval (CI).
Results: Eleven studies published in 2012 − 2022 recruiting
a total of 5195 patients were included in the meta-analysis.
The prevalence of reherniation in ACD and control groups
was 23.2% (95% CI: 18.2% − 28.1%) and 36.4% (95% CI:
28.2% − 44.5%), respectively. The moderator effect of
sample size is significant for pooled data of the ACD group
(p-mod=0.002), but not for the control group (pmod=0.278). After the adjustment with sample size, the
prevalence rates were 13.6% (95% CI: 6.2% − 21.1%) and
29.6% (95% CI: 14.9% − 33.2%) for ACD and control
groups, respectively.
Conclusion: Comparatively to lumbar discectomy alone,
using a Bone-anchored annular closure device following
lumbar discectomy decreased the symptomatic reherniation
rate and post-operative complications, as well as the
necessity for subsequent surgeries.

BACKGROUND AND OBJECTIVES
The global pandemic caused by Coronavirus Disease 2019 (COVID-19) has affected millions, with growing evidence of the potential role of ocular tissues in viral transmission. At the time of writing, local data regarding the phenomenon was limited. This study investigated external ocular manifestations in patients with COVID-19 at a referral center in the Philippines, examined correlations between demographics, systemic manifestations, and laboratory results with ocular manifestations, and determined their timing relative to systemic symptoms.
METHODSThis single-center, descriptive cross-sectional study was carried out from December 8 to 18, 2020 at the adult COVID-19 wards of the Philippine General Hospital involving 72 participants. Data collection involved relevant clinical history taking and performing gross eye examination. The prevalence of ocular manifestations was described with 95% confidence intervals. Correlations between ocular manifestations and quantitative variables were analyzed with point-biserial correlation, and associations with qualitative variables were tested using chi-square or Fisher’s exact tests.
RESULTSAmong participants, 31.9% presented with ocular manifestations with foreign body sensation as the most prevalent ocular symptom (11.1%) and conjunctival hyperemia as the most prevalent ocular finding (19.4%). The median age of patients with ocular manifestations was 41 years old with a higher prevalence in the male population (73.9%, CI=95%, p=0.001). No significant correlation was observed between presence of external ocular manifestations and the different systemic and ocular co-morbidities as well as with COVID-19 clinical classification. Among those who experienced symptoms, majority (29.2%) of the patients experienced systemic symptoms prior to the onset of ocular symptoms. Ocular complaints may present as the sole manifestation (13.9%). Several laboratory parameters were measured and only temperature and AST levels showed a low positive correlation with the presence of ocular manifestations.
CONCLUSIONOcular manifestations occur in roughly one third of patients with COVID-19 based on this study population. With some individuals presenting with ocular signs or symptoms as the initial and sole manifestation, healthcare practitioners must exercise caution and remain vigilant in managing patients who present as such. At the time of writing, this is the first local study investigating the different external ocular manifestations in patients with COVID-19. There is a need to pursue more robust studies and conduct more local investigations which will guide both ophthalmologists and other practitioners in strengthening existing guidelines regarding precautionary practices, clinical diagnosis, and management of COVID-19 patients.

Currently, thoracic endovascular aortic repair (TEVAR) is recommended for type B aortic dissection to reduce long-term aneurysmal progression and lethal aortic events, however, preoperative risk and managements are still unclear. In this report, we present a case of recurrent embolic cerebral infarction associated with stent graft-induced new entry tear (SINE), which required additional surgical treatment. The patient was a 61-year-old male who underwent Zone 3 TEVAR 34 days after the onset of acute type B dissection. Over the course of approximately 1.5 years, he experienced six episodes of recurrent embolic cerebral infarction. A follow-up contrast-enhanced CT scan revealed migration of the stent graft to the distal side and a SINE (stent-induced new entry) in the left subclavian artery distal to the major curvature. Furthermore, a 4D-MRI showed retrograde blood flow from the proximal end of the stent graft extending to the brachiocephalic artery. Therefore, the patient underwent ascending aortic arch replacement with an open stent graft technique. False lumen thrombus caused by SINE in the distal aortic arch has potential risk of repeat cerebral infarction. Early and precise diagnosis, as well as preventive treatment strategies are warranted.

Objective: This study retrospectively examined the practice of chlorpromazine (CPZ) administration for sleep disturbance in a palliative care unit, with particular attention to concomitant use of midazolam (MDZ). Methods: A total of 126 patients were reviewed. Among them, 98 patients who continued CPZ for three days or longer were evaluated for changes in nighttime sleep status using a sleep score and for daytime consciousness level. Results: MDZ was used concomitantly in 99 patients (78.5%). Adverse events related to CPZ were observed in 12 patients (9.5%), mainly oversedation and extrapyramidal symptoms, while no severe circulatory or respiratory suppression was noted. Among the 98 patients who received CPZ continuously for three days or longer, sleep scores showed an improving trend; however, some patients experienced decreased daytime alertness, and the possibility that adverse events were underestimated cannot be excluded. Conclusion: This study was a retrospective, single-center analysis based on medical records and therefore has limitations related to the subjectivity of assessment tools and clinical judgment. Further prospective studies using standardized evaluation scales are required to establish the efficacy and safety of CPZ for sleep disturbance.

Purpose: Medical artificial intelligence (AI) is rapidly being integrated into clinical practice and healthcare systems, raising concerns regarding safety, accountability, and governance. Despite its increasing importance, empirical comparative studies examining differences in perceptions of medical AI among key expert groups remain limited. This study aimed to compare and analyze perceptions of medical AI among medical and non-medical professionals and to systematically identify commonalities and differences across policy- and governance-relevant domains. Methods: Focus group interviews using open-ended questions were conducted with 30 experts (15 medical and 15 non-medical professionals) who had direct experience with medical AI. Data were analyzed using inductive thematic analysis combined with qualitative comparative analysis. Analytical rigor was strengthened through independent coding and consensus-based discussions. Results: Both groups recognized the potential of medical AI to bring meaningful changes to healthcare systems. However, medical professionals primarily evaluated medical AI in terms of clinical applicability, patient safety, explainability, and accountability. In contrast, non-medical professionals emphasized technological maturity, scalability, data infrastructure, standardization, and system-integration potential. Group-specific patterns also emerged regarding perceived limitations, autonomy, educational priorities, and classification frameworks, particularly in relation to clinical risk management versus system-level design and governance considerations. Conclusion: Differences in perceptions of medical AI are systematically associated with distinct interpretive frames shaped by professional roles and responsibility structures. Effective implementation and policy design for medical AI therefore require an integrated approach that accounts for these structural differences. This study provides empirical evidence and a conceptual foundation for future quantitative and mixed-methods research on medical AI governance.

Background:
The effects of perioperative ketamine and esketamine on postoperative nausea and vomiting (PONV) remain unclear. This study aimed to clarify their impact on PONV and related adverse events.
Methods:
We performed a meta-analysis of randomized controlled trials and observational studies comparing ketamine or esketamine with control agents. The primary outcome was a pooled analysis of PONV and nausea-only data. PONV, postoperative nausea (PON), and postoperative vomiting (POV) were also analyzed separately. Subgroup analyses were conducted by comparator type (placebo, opioid, or non-opioid) and dose categories. Meta-regression was used to assess dose-response relationships.
Results:
Fifty-five studies (n = 6676) were included. Ketamine and esketamine did not significantly reduce the incidence of pooled PONV risk (risk ratio [RR]: 0.95, 95% CI [0.87–1.04], P = 0.274). No benefit was found versus placebo. Compared with opioids, PONV was reduced (RR = 0.50, 95% CI [0.32–0.77], P = 0.002), but not in the pooled analysis (RR = 0.69, 95% CI [0.43–1.08], P = 0.107). Conversely, compared with non-opioid controls, ketamine/esketamine increased the pooled PONV risk (RR = 1.46, 95% CI [1.03–2.05], P = 0.032). No significant dose-response relationship was found. Both agents increased hallucinations (RR = 1.73, 95% CI [1.35–2.20], P = 0.0002) and drowsiness (RR = 2.18, 95% CI [1.13–4.21], P = 0.024).
Conclusions
Ketamine and esketamine did not significantly reduce PONV overall. While they showed benefits compared with opioid-based regimens, they may be less effective than non-opioid adjuvants. However, their neuropsychiatric and sedative risks warrant cautious use.
7.Efficacy of pectoral nerve II block for flap dissection-related pain following robot-assisted transaxillary thyroidectomy: a prospective, randomized controlled trial
Korean Journal of Anesthesiology 2026;79(1):69-81
Background:
Robot-assisted transaxillary thyroidectomy (RATT) involves extensive flap dissection, leading to significant postoperative pain. This study evaluated the efficacy of pectoral nerve II (PECS II) block in pain relief, opioid reduction, and recovery enhancement.
Methods:
This prospective, randomized controlled trial included 83 patients undergoing elective RATT for thyroid conditions. Patients were assigned to the block group (n = 42) or non-block group (n = 41). Pain was assessed using the visual analog scale (VAS) at 1, 4, 24, and 48 h postoperatively. Secondary outcomes included opioid consumption and Quality of Recovery-15 (QoR-15K) scores at discharge.
Results:
The PECS II block group had significantly lower VAS scores at 1 h (3.6 ± 2.5 vs. 6.3 ± 2.3, P < 0.001), 4 h (2.6 ± 2.1 vs. 4.3 ± 2.5, P = 0.002), and 24 h (2.0 ± 1.6 vs. 3.2 ± 2.0, P = 0.002). Opioid consumption was significantly lower in the block group (median: 1 [0.75, 3] vs. 3 [2, 3.5], P = 0.001). QoR-15K pain subdimension scores were higher in the block group (14.5 [12, 17] vs. 10 [8, 14], P < 0.001), while other recovery aspects were comparable.
Conclusions
The PECS II block significantly reduces pain and opioid use in RATT patients, enhancing recovery quality. This opioid-sparing approach supports multimodal pain management, ensuring safer and more comfortable postoperative recovery.
8.Factors that Should Be Additionally Included in Blood Transfusion Consent

Korean Journal of Blood Transfusion 2026;37(1):29-31
Informed consent for blood transfusion should include information that supports the decision to agree or disagree to the transfusion. Adverse reactions, including transfusion-transmitted infections, hemolysis, allergic reactions, fever, and volume overload, are listed in informed consent. Nevertheless, alloantibody formation, platelet refractoriness, and iron overload are not included in the informed consent. Therefore, a consent form that includes these factors should be considered for patients receiving transfusions to support decision-making.

Purpose:
Atypical hyperplasia (AH) management remains controversial due to variable malignant disease progression rates. While Western studies report 10% to 25% upgrade rates, data from Asian populations, particularly from referral academic centers, are limited. We aimed to identify predictive factors for malignant upgrade in Korean women with AH at academic hospitals.
Methods:
This retrospective multi-institutional study analyzed 340 patients diagnosed with AH on initial biopsy who underwent subsequent excision at five Korean academic hospitals from 2000 to 2022. Malignant upgrade was defined as ductal carcinoma in situ or invasive cancer on the final pathology. Multivariate logistic regression was used to identify independent predictors of upgrades.
Results:
Among 340 patients (319 atypical ductal hyperplasia, 20 atypical lobular hyperplasia, and 1 mixed), 128 (37.6%) experienced a malignant upgrade, 98 (76.6%) to ductal carcinoma in situ, and 30 (23.4%) to invasive cancer. In multivariate analysis, multifocal atypia (odds ratio [OR], 25.61; 95% confidence interval [CI], 11.20–58.55; P<0.001) and Breast Imaging-Reporting and Data System 4c-5 lesions (OR, 11.02; 95% CI, 1.43–84.86; P=0.021) were significant predictors. Multifocal atypia showed an 84.4% upgrade rate. Core needle biopsy had higher upgrade rates than vacuum-assisted biopsy (45.2% vs. 20.0%; P<0.001). The upgrade rates decreased from 50% to 25% over the study period (P<0.05).
Conclusion
The 37.6% upgrade rate in this tertiary referral cohort exceeded that in Western reports, with multifocal atypia emerging as the strongest predictor. These findings support immediate excision for multifocal atypia while allowing individualized management for unifocal lesions with favorable imaging in Korean tertiary care settings.
