| 抄録 | Emicizumab, a bispecific monoclonal antibody, benefits patients with severe hemophilia A. It alters laboratory assessments of coagulation activity, requiring anti-idiotype monoclonal antibodies for accurate monitoring. A 64-year-old man, receiving emicizumab regularly, was admitted for laminoplasty. We planned to use FVIII replacement during the perioperative period after confirming the disappearance of inhibitors, monitoring coagulation activity with anti-idiotype monoclonal antibodies. Activated partial thromboplastin time was prolonged on postoperative day 2, prompting an immediate switch to eptacog alfa. The patient recovered without bleeding. This case underscores the necessity of anti-idiotype monoclonal antibodies for accurate monitoring. |

| 抄録 | The optimal indications for intensive care unit (ICU) treatment for critically ill cancer survivors whose condition has deteriorated due to medical factors are unclear. To test our hypothesis that frailty before deterioration was associated with hospital mortality in this patient population, we retrospective analyzed the cases of the patients admitted to the ICU at the National Cancer Center Hospital, Japan (April 2014-March 2022). We excluded patients who underwent surgery within 28 days or were denied critical care within 24 h or admitted after cardiopulmonary arrest. Their Clinical Frailty Scale (CFS) scores at 1 month before ICU admission (Pre-ICU) were obtained. Frailty was defined as CFS scores ≥4 points. We analyzed 298 admissions and observed that the mortality rate at hospital discharge was significantly higher in the frailty group (n=119). A multivariate analysis demonstrated that the following factors were significantly associated with hospital mortality: Pre-ICU frailty (OR 2.00, 95%CI: 1.19-3.36, p=0.009), cancer type (hematological: OR 2.93, 95%CI: 1.42-6.05, p=0.004), and Sequential Organ Failure Assessment score at ICU admission (OR 0.88, 95%CI: 0.82-0.95, p=0.0008). Frailty retrospectively assessed using the CFS at 1 month pre-ICU admission is a risk factor for hospital mortality in these cancer survivors. |

| 抄録 | Radon (222Rn; Rn) and thoron (220Rn; Tn) inhalation have been reported to enhance antioxidant activity in various organs. However, the effects of Tn on the colon have not been investigated. This study aimed to clarify the effects of Tn inhalation, alone and in combination with cyclosporin A (CsA), on dextran sulfate sodium (DSS)-induced colitis, and the accompanying oxidative stress, in mice. Male BALB/c mice were subjected to continuous 8-day Tn inhalation (c-Tn, 533±128 Bq/m3) or alternate-day Tn inhalation over the same period (f-Tn, 577±63Bq/m3), followed by treatment with 3% DSS and either CsA or vehicle for 7 days. Although the disease activity index (DAI) decreased significantly by day 2 in the c-Tn group, scores remained significantly higher than those in the f-Tn group. In the c-Tn group, superoxide dismutase and catalase activity in the colon were significantly elevated compared with those in sham controls. Thus, DSS-induced damage was effectively inhibited in the earlier stages by the c-Tn mode of inhalation than by the f-Tn mode. These findings suggest that continuous Tn inhalation more effectively attenuated early colitis symptoms than alternate-day inhalation, potentially through upregulation of antioxidant defenses. Tn and CsA showed no combined effects. |

| 抄録 | Several observational studies suggested that migraine headache attacks were associated with coronavirus disease 2019 (COVID-19). We investigated genetic causal links between COVID-19 phenotypes and the development of headache and migraine, including migraine with aura (MA) and migraine without aura (MO). We conducted a two-sample Mendelian randomization (MR) analysis to estimate the genetic association in European populations. The inverse-variance weighted (IVW) method was used as the main approach in the MR analyses, together with weighted median and MR-Egger methods. We also performed a series of sensitivity tests to assess the robustness of the MR results. The MR results demonstrated that COVID-19 severity, hospitalization, and susceptibility had no causal effect on the risks of headache, migraine, MA, or MO. No horizontal pleiotropy was detected, and the results were robust as supported by the sensitivity analysis findings. Our analyses identified no casual effect of COVID-19 severity, hospitalization, or susceptibility on the risks of headache or migraine in European populations. |

| 抄録 | We investigated the treatment outcomes of patients aged ≥85 years with neovascular age-related macular degeneration (nAMD) who received anti-vascular endothelial growth factor (anti-VEGF) therapy using either treat-and-extend (TAE) or pro re nata (PRN) regimens for 1 year in real-world clinical practice. Eighty-five eyes from 85 patients were included. Among them, types 1, 2, and 3 macular neovascularization and polypoidal choroidal vasculopathy were present in 27.1%, 17.6%, 18.8%, and 36.5%, respectively. TAE and PRN regimens were used in 43.5% and 56.5% of patients, respectively. At baseline, the PRN group was older and had worse best-corrected visual acuity (BCVA), greater central retinal thickness, and more intraretinal fluid than the TAE group. In the TAE group, the mean number of injections was 7.6, BCVA improved significantly, and all retinal fluid rates decreased. In the PRN group, the mean number of injections was 3.9, BCVA remained unchanged, and the rates of macular fibrosis and atrophy increased. No serious adverse events were observed in either group. Anti-VEGF therapy was safe for patients aged ≥ 85 years with nAMD, and the TAE regimen effectively improved BCVA in this population. BCVA remained unchanged in the PRN-treated patients, with baseline disease severity and/or undertreatment potentially influencing the outcomes. |

| 抄録 | Pancreatoduodenectomy (PD) after esophagectomy with gastric conduit reconstruction is technically challenging. Preserving the blood supply of the gastric conduit is crucial in performing PD after esophagectomy. We report the case of a 66-year-old man who underwent gastroduodenal artery-preserving PD after esophagectomy with gastric conduit reconstruction for intraductal papillary mucinous neoplasm. The patient developed pseudoaneurysm rupture postoperatively, but was successfully treated with interventional radiology. Precise assessment is important in developing a surgical strategy depending on the patient’s specific anatomy and tumor characteristics. Moreover, special attention should be paid to avoid accidental injuries of the gastric conduit and gastric vessels during surgery. |

| 抄録 | Trigonal meningiomas are rare and pose surgical challenges due to their deep location and proximity to critical neuroanatomical structures. We present the case of a 67-year-old woman with a growing trigonal meningioma successfully resected with guidance by a preoperative 3D imaging analysis system. Integration of CT and MRI including diffusion tensor imaging (DTI) enabled precise mapping of the optic radiation, guiding a middle temporal gyrus approach. Preoperative embolization reduced tumor vascularity, facilitating gross total resection with minimal blood loss. This case highlights the effectiveness of preoperative 3D imaging systems in optimizing surgical planning and improving outcomes in complex neurosurgical cases. |

| 抄録 | We report the case of a 72-year-old Japanese man with an incidental portal vein mass that was surgically resected and diagnosed as immunoglobulin G4 (IgG4)-related disease. The mass was discovered during an atrial fibrillation examination. The patient had a history of gastric cancer and was also diagnosed with rectal cancer, raising concerns about metastasis. Due to technical challenges, a biopsy was not feasible. Imaging findings suggested portal vein tumor thrombosis, complicating the diagnosis. This case highlights a rare presentation of IgG4-related disease mimicking portal vein tumor thrombus. |

| 抄録 | Single-position surgery with lateral lumbar interbody fusion (LLIF) and percutaneous pedicle screws (PPSs) is gaining attention for its reduced invasiveness. We developed SPAPS, a technique allowing two surgeons to perform anterior LLIF and posterior PPS insertion simultaneously in a single lateral decubitus position. This retrospective study compared SPAPS (SPAPS-LLIF, Group SL) and minimally invasive posterior/transforaminal lumbar interbody fusion (MIS-PLIF/TLIF, Group PT) in patients treated between 2016 and 2019 with a two-year follow-up. Operative time, estimated blood loss (EBL), length of hospital stay (LOS), JOABPEQ and VAS scores, segmental lordotic angle, lumbar lordotic angle, segmental Cobb’s angle, PPS misplacement, PPS loosening, fusion status, and muscle cross-sectional areas were compared. Fifty-two patients were analyzed (Group SL: 25; Group PT: 27). SPAPS significantly reduced operative time (118.0 vs. 165.3 min, p <0.01) and estimated blood loss (8.6 vs. 164.1 mL, p<0.01). While clinical outcomes and hospital stay were comparable, Group SL had significantly lower PPS loosening (0% vs. 13%, p<0.01) and non-union rates (0% vs. 22.2%, p=0.02). Multifidus muscle atrophy was also less in Group SL (−14.3 vs. −121.5 mm2, p<0.01). SPAPS demonstrated advantages in reducing surgical invasiveness without compromising clinical efficacy, offering a promising alternative to conventional posterior fusion surgery. |

| 抄録 | To analyze and characterize the medial and lateral rectus muscles in patients with exotropia using anterior segment optical coherence tomography (AS-OCT). This study included 24 patients with exotropia (48 eyes) and 25 healthy individuals (50 eyes). Anterior segment optical coherence tomography was used to construct the en face images. The anterior chamber angle to the extraocular muscle insertion distance, muscle width, and muscle fiber angle from the muscle insertion sites were compared between the exotropia and the control groups. The correlation between these parameters and age or angle of deviation was evaluated. The mean ages were 13.2±4.1 years for the exotropia group and 17.6±7.2 years for the control group. The lateral rectus angle was significantly more inwardly rotated in the exotropia group than in the control group (1.6±6.3°, −1.4±4.0°, p=0.014). With increasing angle of deviation, the width of the lateral rectus increased (p=0.002). Our results indicate that the lateral rectus angle is significantly more inwardly rotated in patients with exotropia. These findings should contribute to a deeper understanding of the extraocular muscles in patients with this condition. |

| 抄録 | Clostridium perfringens is a pathogenic anaerobe that causes gas gangrene and food poisoning. Although autolysin-mediated reorganization of the bacterial cell wall is crucial for cell division, excessive autolysin activity induced by stressors can lead to cell lysis. In C. perfringens, air exposure is a significant stressor that causes cell lysis, and Acp (N-acetylglucosaminidase) is known to be a major autolysin. To further facilitate C. perfringens research, a technology to prevent air-induced cell lysis must be developed. This study investigated the role of Acp in air-induced autolysis and explored potential inhibitors that would prevent cell lysis during experimental procedures. Morphological analyses confirmed that Acp functions as an autolysin in C. perfringens, as acpdeficient strains exhibited filamentous growth. The mutants exhibited negligible autolysis under air-exposure stress, confirming the involvement of Acp in the autolytic process. We also evaluated the effects of various divalent cations on Acp activity in vitro and identified Zn2+ as a potent inhibitor. Brief treatment with a Zn2+- containing buffer induced dose-dependent cell elongation and autolysis inhibition in C. perfringens. These findings demonstrate that simple Zn2+ treatment before experiments stabilizes C. perfringens cells, reducing autolysis under aerobic conditions and facilitating various biological studies, except morphological analyses. |

| 抄録 | Primary graft dysfunction (PGD) is one of the major risk factors affecting patients’ short- and long-term survival after lung transplantation. No particular management strategy has been established for PGD; supportive care is the mainstay of PGD treatment. When a supportive strategy fails, the patient may require the introduction of extracorporeal membrane oxygenation (ECMO) as the last-resort measure for severe PGD. A variety of study of ECMO as a PGD treatment was reported and the management of PGD patients developed so far. Early recognition of a patient’s need for ECMO and its prompt initiation are critical to improved outcomes. The use of venovenous-ECMO became the preferred procedure for PGD rather than venoarterial-ECMO. However, the current ECMO strategy has limitations, and using ECMO to manage patients with PGD is not sufficiently effective. Further studies are required to develop this promising technology. |

| 抄録 | Bile leak occurs in 2-25% of liver transplant, 3-27% of hepatic resection, and 0.1-4% of cholecystectomy cases. The clinical course of bile leak varies depending on the type of surgery that caused the fistula, as well as the type, severity, and timing of bile duct injury. Although infections resulting from bile leak can be life-threatening, the introduction of endoscopic treatment has enabled some patients to avoid reoperation and has reduced the negative impact on quality of life associated with external fistulas for percutaneous drainage. Endoscopic interventions, such as sphincterotomy and stent placement, reduce the pressure gradient between the bile duct and duodenum, facilitating bile drainage through the papilla and promoting the closure of the leak. We reviewed the literature from 2004 to 2024 regarding bile leak following cholecystectomy and liver surgery, examining recommended techniques, timing, and treatment outcomes. In cases of bile leak following cholecystectomy, clinical success was achieved in 72-96% of cases, while success rates for bile leak following liver surgery ranged from 50% to 100%. Although endoscopic treatment is effective, it is not universally applicable, and its limitations must be carefully considered. |

| 抄録 | A 55-year-old obese Japanese male with left pneumothorax presented to our hospital. Bilateral pulmonary emphysema was confirmed. Persistent air leakage was observed, and a thoracoscopic bullectomy was performed. Although the thoracoscopic bullectomy was completed uneventfully, pre-extubation chest X-ray imaging indicated hyper-lucency occupying the right upper part of the thoracic cavity, suggesting right-sided pneumothorax. CT imaging indicated a right-upper-lobe expanded bulla. Extubation was performed, and the hyperinflated bulla gradually deflated. Careful management of bulla expansion and respiratory status may be necessary for patients with obesity and large bullae, especially in one-lung ventilation cases. |
