抄録 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.

抄録 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.

抄録 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.

抄録 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.

抄録 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.

抄録 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.

抄録 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.

抄録 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.

抄録  This study constructs a model of anticompetitive exclusive dealing in the presence of complementary inputs. Kitamura, Matsushima, and Sato (2018) analyze the situation where a downstream firm transforms multiple complementary inputs into final products. When complementary input suppliers have market power, the inefficient incumbent supplier can deter socially efficient entry by using exclusive contracts. This study applies the analysis from Kitamura, Matsushima, and Sato (2018) to examine a situation where the potential entrant produces horizontally differentiated products and demonstrates the feasibility of anticompetitive exclusive dealing.
