| Abstract | A 65-year-old man was referred to our hospital for the annual assessment of the diameter and dilation of a pulmonary artery (PA) aneurysm. He had a small ventricular septal defect (VSD) that had closed naturally. Echocardiography revealed a dilated main PA, mild pulmonary regurgitation and no VSD. Computed tomography confirmed the dilation of the main PA (66.7×47.8 mm), right PA (37.1×32.9 mm), and left PA (36.7×34.0 mm). The patient underwent pulmonary artery replacement using a prosthetic vascular graft. A quadricuspid pulmonary valve was identified intraoperatively. Early surgical intervention could help to prevent rupture and dissection of PA aneurysms. |

| Abstract | 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. |

| Abstract | Pneumonic-type adenocarcinoma (P-ADC) can closely mimic pneumonia. We report a P-ADC initially diagnosed as pneumonia which developed into a pulmonary abscess and empyema. A 50-year-old Japanese male diagnosed with pneumonia, pulmonary abscess, and empyema was administered antibiotics and a chest tube for drainage, which improved his symptoms and blood test results. However, chest computed tomography showed an enlarged infiltrative shadow. The patient underwent bronchoscopy and was diagnosed with an adenocarcinoma. This case highlights the importance of considering P-ADC in differential diagnoses when a pneumonia-like shadow enlarges post-empyema treatment. Diagnostic and clinical tests, e.g., bronchoscopy, should be performed in such cases. |

| Abstract | Pulmonary cement embolism (PCE) is a rare but severe complication following percutaneous vertebroplasty (PVP). Calcium phosphate cement (CPC) has emerged as an alternative to traditional materials for vertebral augmentation. There appear to be no established guidelines for managing symptomatic PCE, and there is scarce literature on CPC embolisms. This is a first report of a case of pulmonary CPC embolism following PVP. The patient, a 63-year-old Chinese female, was administered anticoagulant treatment and achieved a satisfactory outcome. Her case highlights the severe potential morbidity associated with CPC leakage and emphasizes the efficacy of anticoagulant treatment for managing pulmonary CPC embolisms. |

| Abstract | GNAO1 variant affects primarily the brain and neurodevelopment, leading to a range of motor disorders including seizures beginning in infancy and involuntary movements such as dyskinesia and dystonia. Our patient, a 15-year-old Japanese female, began exhibiting involuntary movements at age 4. A de novo missense mutation (NM_020988.3: c.228C>G, NP_066268.1: p.(Asn76Lys)) in the GNAO1 gene was identified when the patient was 15, and during the same year she developed influenza pneumonia, accompanied by dystonic storm. She required intensive care with mechanical ventilation and underwent a tracheostomy. She also developed posterior reversible encephalopathy syndrome. Globus pallidal stimulation was administered, leading to an improvement in the dystonic storm. Early consideration of globus pallidal stimulation is recommended when treating difficult-to-manage dystonic storms. |

| Abstract | We report a case of drug-resistant parieto-occipital lobe epilepsy successfully treated with parieto-occipital disconnection (POD). An 18-year-old left-handed female, who had undergone surgery for an acute subdural hematoma at 10 months of age, developed drug-resistant epilepsy at age 15. Despite antiepileptic drug treatment, her seizures remained uncontrolled, and at age 18 she was referred to our hospital for evaluation. Magnetic resonance imaging (MRI) revealed atrophy in the left occipital and parietal lobes. Ictal electroencephalography (EEG) confirmed occipital onset of seizures without temporal lobe involvement. She had pre-existing homonymous hemianopsia. POD surgery was performed, carefully preserving the temporal lobe structures. Postoperatively, she experienced transient right-sided paresis, which fully resolved, and achieved complete seizure control at 3 years without memory loss. This case demonstrates that POD, a rare surgical approach, is a viable option for parieto-occipital lobe epilepsy, effectively controlling seizures while minimizing functional impairment in the absence of temporal lobe involvement. |

| Abstract | A 76-year-old man presented with right eyelid swelling and deteriorated vision. Examination revealed anterior uveitis with hypopyon and a visual acuity of 20/2,000 in the right eye, with no abnormalities in the left. Computed tomography revealed enlargement of the right maxillary sinus and internal fluid accumulation, suggesting a postoperative maxillary cyst (POMC). Nasal endoscopic surgery drained the pus by opening the lower wall of the maxillary cyst. Following the procedure, intraocular inflammation resolved, and visual acuity in the right eye improved to 24/20. This is the first reported case of uveitis secondary to POMC. |

| Abstract | An 80-year-old male underwent an extended cholecystectomy for node-positive gallbladder adenocarcinoma. Two weeks later, hemoptysis revealed a left hilar tumor obstructing the bronchus, which was diagnosed as adenocarcinoma. Three months post-cholecystectomy, a left upper pulmonary lobectomy was performed. Histological similarity and positive thyroid transcription factor-1 (TTF-1) immunostaining in both tumors confirmed lung adenocarcinoma with gallbladder metastasis. Despite the generally poor prognosis for gallbladder metastasis from lung cancer, the patient achieved 3 years of survival. Patients with isolated synchronous gallbladder metastasis from lung cancer may benefit from oligometastasectomy. |

| Abstract | The global femoral offset (the sum of the acetabular and femoral offsets) influences outcomes after total hip arthroplasty (THA). The optimal offset using plain radiographs has been reported, but internal and external rotations of the hip affect the offset value, producing unclear results when the nonsurgical side is not intact. We investigated the relationship between a functional hip score, i.e., the Harris Hip Score (HHS) and its effect on the post-THA anteroposterior and lateral offsets, and we sought to identify the optimal offset value. The cases of 158 patients with hemilateral hip osteoarthritis who underwent THA at a single center were retrospectively analyzed in this cross-sectional study. Three-dimensional pelvic and femoral models generated from computed tomography were used to examine several parameters, and the results revealed a significant binomial correlation among the modified HHS and femoral and global femoral offsets, with maximum values of 21.3 mm and 40 mm/100 cm body height, respectively. Pelvic and femoral parameters were measured and evaluated via alignment with a specific coordinate system. Our findings indicate that preoperative planning using these parameters may improve postoperative hip function, even when the nonoperative side is unsuitable for use as a reference, as in bilateral hip osteoarthritis cases. |

| Abstract | Cervical spondylotic myelopathy (CSM) and ossification of the posterior longitudinal ligament (OPLL) increase the likelihood of spinal cord injury without radiographic evidence of trauma (SCIWORET). Opinions regarding the optimal timing for surgery in such cases vary, however. We retrospectively investigated the demographics and outcomes of patients with SCIWORET who underwent surgery shortly after experiencing rapid neurological deterioration, and we matched patients who underwent standby surgery for CSM or OPLL. Although the optimal timing of surgery for SCIWORET remains unclear, our findings suggest that early stage surgery for SCIWORET may yield favorable neurological improvements. |

| Abstract | This study investigated the risk factors for bone fragility and perioperative periprosthetic femoral stem fractures in patients undergoing hip arthroplasty for femoral neck fractures. The records of 215 patients (42 male, 173 female; mean age, 84.4 years) were analyzed to assess correlations among periprosthetic fracture rates and sex, age, body mass index (BMI), Dorr classification, femoral stem fixation type (cemented/cementless), and bone mineral density (BMD) of the contralateral proximal femur. The overall prevalence of perioperative periprosthetic fractures was 4.7%. All patients with periprosthetic fractures were female, and all but one were ≥ 80 years of age. Fracture rates were higher in patients with lower BMI, although this difference was not significant. The fracture rates were 0%, 4.7%, and 7.9% for Dorr types A, B, and C, respectively, and 0% and 5.3% for patients who received cemented and cementless stems, respectively. The findings indicated that female patients, those of advanced age, those with lower BMI, and those with Dorr type C had lower BMDs. Although BMD was significantly lower in patients who received cemented stems compared to those who received cementless stems, no fractures were observed in the former group, suggesting that the use of cemented stems is safe for this high-risk population. |

| Abstract | We investigated the work productivity levels of employed cancer survivors and non-cancer-survivor workers by conducting a cross-sectional study in Japan between February and March 2019, using an online survey. A total of 561 employed individuals aged 20-64 years were analyzed. Work productivity was assessed using the Work Productivity and Activity Impairment-General Health questionnaire which evaluates absenteeism, presenteeism, and overall work productivity loss. The questionnaire responses demonstrated that the cancer survivors within 1 year of diagnosis had significantly higher absenteeism compared to the non-cancer workers (p=0.048). Although presenteeism and overall work productivity loss were also higher in the non-cancer-survivor group, the differences were not significant. Cancer survivors within 1 year of diagnosis exhibited higher absenteeism, but their work productivity appeared to recover to levels comparable to those of the non-cancer workers over time. These findings may contribute to workplace policies supporting cancer survivors’ return to work. |

| Abstract | Bloodstream infections (BSIs) are an important cause of morbidity and mortality in geriatric patients. We retrospectively analyzed the cases of geriatric patients who developed BSIs due to gram-negative bacteria in order to evaluate the epidemiology, antimicrobial resistance, and the factors affecting mortality. The cases of 110 patients aged ≥ 65 years admitted to our hospital between January 1, 2017, and December 31, 2022 were assessed; 70 (63.6%) of the BSIs were healthcare-associated BSIs. The urinary system was the most common detectable source of infection at 43.6%. The most frequently isolated bacteria were Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae, in that order. Carbapenem resistance was detected in 17 patients (15.5%), and extended-spectrum beta-lactamase (ESBL) production from Enterobacterales family members was detected in 37 (51.4%) patients. Multivariate analysis revealed that (i) the probability of mortality in the patients with total bilirubin was increased by approx. sixfold and (ii) the likelihood of mortality for those with a Pitt bacteremia score (PBS) ≥ 4 points was approx. 17 times higher. PBS and simplified qPitt scores can help predict mortality and manage geriatric patients. There is a significant increase in mortality among patients with procalcitonin (PCT) levels at ≥ 2 nm/ml. |

| Abstract | Extracorporeal cardiopulmonary resuscitation (ECPR) has evolved into a life-saving therapy for select cardiac arrest patients, yet a growing body of evidence suggests it also holds promise as a bridge to organ donation in non-survivors. This review explores the clinical outcomes, ethical complexities, and evolving policies surrounding organ donation after ECPR. We summarize recent international and Japanese data demonstrating favorable graft function from ECPR donors, with the exception of lung transplantation. The ethical challenges — particularly those involving brain death determination on extracorporeal membrane oxygenation and adherence to the dead donor rule — are discussed in the context of Japan’s recent regulatory reforms. Additionally, we highlight the importance of structured end-of-life communication through multidisciplinary team meetings in facilitating ethically sound transitions from rescue efforts to donation pathways. Moving forward, improvements in donor management, standardized legal frameworks, and public and professional education are essential to optimizing the life-saving and life-giving potential of ECPR. |

| Abstract | Renal cell carcinoma (RCC) can metastasize hematogenously and recur after a long dormancy. Chromophobe RCC metastasized to the cervical lymph nodes 10 years after the primary resection in a woman who underwent nephrectomy for RCC (T1aN0M0 stage I). Metastatic RCC diagnosis was confirmed by aspiration. The lymph node mass was resected, and the tumor cells matched chromophobe RCC metastasis. No adjuvant therapy was administered due to the lack of evidence regarding adjuvant therapy for chromophobe RCC. Long-term surveillance is crucial in RCC because of the possibility of late metastasis. We reviewed the clinical aspects and literature on metastatic cervical RCC. |

| Abstract | A 38-year-old man was brought to the hospital for emergency treatment of cyanosis. The patient exhibited generalized cyanosis and impaired consciousness despite adequate oxygen therapy. Arterial blood was black, and arterial blood gas analysis revealed an abnormally high methemoglobin level of 67.8%. We later interviewed his colleagues regarding his exposure to aniline while working at the factory and diagnosed him with methemoglobinemia due to aniline poisoning. The patient was administered methylene blue (MB) after being transferred to another hospital, where this treatment was available, resulting in an improvement in symptoms. Although rare, methemoglobinemia is serious. A good understanding of the circumstances at disease onset, characteristic findings, and abnormal values of methemoglobinemia is important. In addition, MB is an important therapeutic for the treatment of methemoglobinemia; if MB is not available at a particular hospital, transfer of the patient to a hospital that stocks MB should be considered. |

| Abstract | Perigraft seroma, a sterile fluid accumulation around the graft, is a potential complication after thoracic aortic surgery. The optimal treatment strategy for a perigraft seroma with vascular compression after thoracic aortic surgery has been unclear. We describe the case of a 62-year-old Japanese male in whom an asymptomatic perigraft seroma was observed after he had undergone aortic root replacement for annulo-aortic ectasia. The seroma was successfully treated with thoracoscopic drainage and conservative therapy. Less invasive therapy, including conservative therapy, may also be an option for asymptomatic perigraft seromas observed after thoracic aortic surgery. |

| Abstract | A 67-year-old woman with rheumatoid arthritis presented with an untriggered hematoma in the right shoulder joint. Radiographic findings showed humeral head collapse and destruction of the glenoid fossa with ectopic calcification. Calcium pyrophosphate deposition (CPPD) in the synovial fluid was observed using a polarizing microscope. Histopathological findings revealed chronic inflammatory cell infiltration and giant cells surrounded by CPPD. The patient was diagnosed with rapid destructive arthropathy (RDA). Endoscopic shoulder joint debridement was performed. Postoperatively, active flexion improved from 40 to 75 degrees. This case highlights that CPPD can cause RDA in the shoulder, detectable with detailed histopathology. |

| Abstract | We investigated the emotional changes that young patients with breast cancer need to undergo in order to foster relationship-building with their partners by conducting a qualitative descriptive study (March 1 to Nov. 26, 2021) and semi-structured interviews with eight postoperative patients (age 20-40 years) with breast cancer. The data were analyzed using the modified grounded theory approach (M-GTA), yielding five categories: (i) Awareness of being a breast cancer patient, (ii) Being at a loss, (iii) Support from significant others, (iv) The struggle to transition from being a patient with cancer to becoming “the person I want to be”, and (v) Reaching the “me” I want to be who can face building a relationship with a partner. These findings suggest that young breast cancer patients must feel that they can lead a normal life through activities such as work or acquiring qualifications before building relationships with their partners, and that getting closer to their desired selves is important. Nurses can provide information to young patients with breast cancer to assist them in building a solid relationship with their partners. We believe that this support may enhance the patients’ quality of life and help them achieve stronger relationships with their partners. |

| Abstract | The position attained in total hip arthroplasty (THA) is ideally in the center of the horizontal plane of the acetabulum. However, central placement is not always possible. We hypothesized that differences in approach result in individual differences in cup positioning; thus, we investigated the cup positions of 217 hips that underwent THA. The acetabulum’s anteroposterior diameter was measured, and the cups placed within 2 mm of the line perpendicular to the center as a central placement (central). Of the 217 hips, 68, 114, and 35 hips were anterior, central, and posterior, respectively. In 21 hips, anteroposterior deviation was noted. Among patients operated using the anterolateral approach, 48, 93, and 30 hips were anterior, central, and posterior, respectively. Among those operated using the posterolateral approach, 16, 20, and 4 hips were anterior, central, and posterior, respectively. The cup position shifted either anteriorly or posteriorly to the acetabulum in approximately half of all hips operated using both approaches and tended to shift anteriorly in the hips operated using the posterolateral approach. During THA surgery, it is important to operate with awareness of the center of the acetabulum. |
