抄録 | Tenosynovial giant cell tumor (TGCT) is a fibrous histiocytic tumor originating in the synovial membrane. While cervical TGCT may not be considered a common diagnosis preoperatively because it is relatively rare, it has a high recurrence rate and should be considered. Total resection is preferable, but it can be challenging due to the risk of damaging the vertebral artery. Denosumab has shown effectiveness as a postoperative treatment for osteolytic bone lesion. Denosumab administration coupled with close follow-up might offer an effective postoperative treatment option for unresectable TGCT with bone invasion. |

抄録 | Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment, but they have been known to cause immune-related adverse events (irAEs) by promoting T-cell activation. Neurological irAEs are rare (1%) but have a high fatality rate (11.5%). Here we report the first case of Bickerstaff brainstem encephalitis (BBE) induced by an ICI. A woman in her 60s with metastatic breast cancer was treated with atezolizumab plus nab-paclitaxel once intravenously. Eighteen days later, she lost consciousness with ophthalmoplegia and was diagnosed with a neurological irAE. She recovered consciousness immediately with the administration of intravenous immunoglobulin (IVIG) but suffered severe permanent peripheral neuropathy. Although it is just one case, this experience shows that BBE occurring as a neurological irAE of ICI cancer treatment may be associated with more severe outcomes than conventional BBE in metastatic cancer. Creating a system for multidisciplinary treatment is essential for ICI therapy. |

抄録 | Here, we describe the unique case of a pneumocephalus originating from an inverted papilloma (IP) in the frontoethmoidal sinus. A 71-year-old man with diabetes presented with headaches and altered consciousness. Imaging revealed the pneumocephalus together with bone destruction in the left frontal sinus. He underwent simultaneous endoscopic endonasal and transcranial surgery using an ORBEYE exoscope. Pathological diagnosis of the tumor confirmed IP. Post-surgery, the pneumocephalus was significantly resolved and the squamous cell carcinoma antigen level, which had been elevated, decreased. This case underscores the importance of a multidisciplinary approach and innovative surgical methods in treating complex sinonasal pathologies. |

抄録 | We investigated how humidified high-flow nasal cannula oxygen therapy (HFNC) with a pulmonary infection control (PIC) window as a ventilation switching indication in combination with atomizing inhalation of terbutaline affects the lung function of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). We examined 140 hospitalized AECOPD patients randomized to control and observation groups. Conventional supportive therapy and invasive mechanical ventilation with tracheal intubation were conducted in both groups, with a PIC window as the indication for ventilation switching. Noninvasive positive pressure ventilation (NIPPV) plus atomizing inhalation of terbutaline was used in the control group. In the observation group, HFNC combined with atomizing inhalation of terbutaline was used. Compared to the control group, after 48-hr treatment and treatment completion, the observation group had significantly increased levels of lung function indicators (maximal voluntary ventilation [MVV] plus forced vital capacity [FVC], p<0.05) and oxygen metabolism indicators (arterial oxygen partial pressure [PaO2], arterial oxygen content [CaO2], and oxygenation index, p<0.05). The comparison of the groups revealed that the levels of airway remodeling indicators (matrix metalloproteinase-2 [MMP-2], tissue inhibitor of metalloproteinase 2 [TIMP-2] plus MMP-9) and inflammatory indicators (interferon gamma [IFN-γ] together with interleukin-17 [IL-17], IL-10 and IL-4) were significantly lower after 48 h of treatment as well as after treatment completion (both p<0.05). These results demonstrate that HFNC with a PIC window as the indication for ventilation switching combined with atomizing inhalation of terbutaline can relieve the disorder of oxygen metabolism and correct airway hyper-reactivity. |

抄録 | Zolpidem, a non-benzodiazepine hypnotic, is primarily used to treat insomnia. In a previous study, pior treatment with non-benzodiazepine receptor agonists was associated with inflammation. The present study aimed to clarify the association between the effects of zolpidem and inflammation in mice treated with lipopolysaccharide (LPS), a known model of inflammation. We assessed the zolpidem-induced loss of righting reflex (LORR) duration 24 h after LPS treatment in mice. Additionally, the expressions of γ-aminobutyric acid (GABA)A receptor subunit and K+-Cl− cotransporter isoform 2 (KCC2) mRNA in the hippocampus and frontal cortex were examined in LPS-treated mice. Pretreatment with LPS was associated with significantly prolonged duration of zolpidem-induced LORR compared to control mice. This effect was significantly attenuated by administering bicuculline, a GABAA receptor antagonist, or flumazenil, a benzodiazepine receptor antagonist, in LPS-treated mice. Compared to controls, LPS-treated mice showed no significant change in the expression of GABAA receptor subunits in the hippocampus or frontal cortex. Bumetanide, an Na+-K+-2Cl− cotransporter isoform 1 blocker, attenuated the extended duration of zolpidem-induced LORR observed in LPS-treated mice. LPS significantly decreased Kcc2 mRNA expression in the hippocampus and the frontal cortex. These findings suggest that inflammation increases zolpidem-induced LORR, possibly through a reduction in KCC2 expression. |

抄録 | The lungs are very complex organs, and the respiratory system performs the dual roles of repairing tissue while protecting against infection from various environmental stimuli. Persistent external irritation disrupts the immune responses of tissues and cells in the respiratory system, ultimately leading to respiratory disease. Neuropeptide Y (NPY) is a 36-amino-acid polypeptide and a neurotransmitter that regulates homeostasis. The NPY receptor is a seven-transmembrane-domain G-protein-coupled receptor with six subtypes (Y1, Y2, Y3, Y4, Y5, and Y6). Of these receptors, Y1, Y2, Y4, and Y5 are functional in humans, and Y1 plays important roles in the immune responses of many organs, including the respiratory system. NPY and the Y1 receptor have critical roles in the pathogenesis of asthma, chronic obstructive pulmonary disease, and idiopathic pulmonary fibrosis. The effects of NPY on the airway immune response and pathogenesis differ among respiratory diseases. This review focuses on the involvement of NPY in the airway immune response and pathogenesis of various respiratory diseases. |

抄録 | A 74-year-old Japanese woman presented with a 45-year history of refractory asthma. She had been treated with inhaled corticosteroids, a long-acting β2-agonist, and a long-acting muscarinic antagonist for 6 months. She also had a repeated viral infection. Her condition had been characterized as a refractory asthma associated with type 2 and non-type 2 traits. We began treatment with tezepelumab. The control of the patient’s asthma symptoms and quality of life improved greatly within 1 month (changes in eosinophil count from 748 to 96 /μL, in FeNO from 32 to 17 ppb, in the Asthma Quality of Life Questionnaire score from 3.59 to 6.68, and in the Asthma Control Test score from 13 to 23). Tezepelumab was effective as an initial biologic agent for a patient with refractory asthma associated with type 2 and non-type 2 traits. |

抄録 | This study aimed to determine which muscle the gluteus maximus, gluteus medius, gluteus minimus (Gmin), or tensor fasciae latae (TFL) contributes most to hip abduction strength and to identify effective sites for cross-sectional area (CSA) Gmin and TFL measurement in hip osteoarthritis (OAhip) patients. Twenty-eight patients with OAhip were included. The muscle CSA and volume were determined using magnetic resonance imaging. Peak isometric strength was determined using hand-held dynamometry. Muscle volumes were normalized to the total muscle volume of hip abductors. Multiple regression analysis was performed. The difference between the CSA of Gmin and TFL was calculated, and correlations with volume and muscle strength were determined. Gmin volume was related to abductor muscle strength (p=0.042). The peak CSA of the Gmin correlated with muscle volume and strength. The CSA of the TFL correlated with volume, with no difference between the CSA of the most protruding part of the lesser trochanter and peak CSA. Gmin volume was strongly related to abductor muscle strength. Peak CSA is a useful parameter for assessing the CSA of the Gmin among patients with OAhip. The CSA of the TFL should be measured at the most protruding part of the lesser trochanter. |

抄録 | The aim of our study was to determine whether the immunohistochemical expression of placental vitamin D receptors is altered in pregnancies complicated by preeclampsia. Vitamin D receptor expression was immunohistochemically analysed in the placentas of three groups: a control group, and early- and late-onset preeclampsia groups. Total immunohistochemical intensity staining of placentas showed that the control group had a median vitamin D receptor (VDR) expression significantly higher than the placentas of mothers with early- and late-onset preeclampsia. There was no difference among the three groups in a semiquantitative analysis of VDR staining of the stroma only. Vitamin D receptors showed lower median expression in preeclampsia-affected pregnancies, especially early-onset preeclampsia. Therefore, Vitamin D receptor expression may be an important marker for normal placentation and preeclampsia onset. |

抄録 | Pulsed radiofrequency (PRF) is a safe method of treating neuropathic pain by generating intermittent electric fields at the needle tip. Resiniferatoxin (RTX) is an ultrapotent agonist of transient receptor potential vanilloid subtype-1 (TRPV1) receptors. We investigated the mechanism of PRF using a rat model of RTX-induced neuropathic pain. After administering RTX intraperitoneally, PRF was applied to the right sciatic nerve. We observed the changes in TRPV1, calcitonin gene-related peptide (CGRP), and brain-derived neurotrophic factor (BDNF) in the dorsal root ganglia by western blotting. Expressions of TRPV1 and CGRP were significantly lower in the contralateral (RTX-treated, PRF-untreated) tissue than in control rats (p<0.0001 and p<0.0001, respectively) and the ipsilateral tissues (p<0.0001 and p<0.0001, respectively). BDNF levels were significantly higher in the contralateral tissues than in the control rats (p<0.0001) and the ipsilateral tissues (p<0.0001). These results suggest that, while TRPV1 and CGRP are decreased by RTX-induced neuronal damage, increased BDNF levels result in pain development. PRF may promote recovery from neuronal damage with concomitant restoration of TRPV1 and CGRP, and exert its analgesic effect by reversing BDNF increase. Further research is required to understand the role of TRPV1 and CGRP restoration in improving mechanical allodynia. |

抄録 | The curriculum at the Department of Pathophysiology in the Periodontal Sciences program at Okayama University includes normative preclinical training (NPT) using phantoms. NPT is given to the whole class of 5 th year students divided in groups of 8 students/instructor. In 2019, an innovative personalized preclinical training (PPT) pilot study was implemented for this group of students whereby two students, each with their own dental unit, were coached by one instructor. The main topics covered were dental ergonomics and endodontics. We aimed to evaluate the effectiveness of PPT in dental ergonomics and endodontics toward increasing the knowledge and future clinical skills of students who had already undergone NPT. A test on endodontics was taken before and after PPT. A questionnaire was completed to assess their perception of improvement regarding the above-mentioned topics. Test scores and questionnaire results both showed that the students’ level of knowledge and awareness of future clinical skills was significantly higher after PPT. This pilot study demonstrated that PPT increased the students’ knowledge and future clinical skills. As preclinical training forms the foundation for clinical practice, investment in future research regarding this personalized approach is likely to enhance students’ understanding and clinical performance. |

抄録 | Eating disorders (EDs) are associated with a high mortality rate. Patients with EDs often experience severe dehydration due to food restriction and/or vomiting. Severely underweight patients are often prescribed bed rest during inpatient care to reduce their energy consumption, and they may thus develop multiple risk factors for venous thromboembolism (VTE). We compared the clinical features of ED inpatients with VTE to those of ED inpatients without VTE. Seventy-one inpatients with ED were treated at Okayama University Hospital’s psychiatric ward in 2016-2020; five were experienced a VTE. Compared to the non-VTE group, the VTE group’s median age and disease duration were greater and the median body mass index (BMI) was lower. The VTE group’s D-dimer peak values were > 5 mg/L. Physical restraint and central venous catheter use were associated with VTE. Longer ED duration and lower BMI might be risk factors for VTE. To make inpatient treatment for ED safer, it is important to avoid the use of physical restraints and central venous catheters. Continuous D-dimer monitoring is necessary for the early detection of VTE in ED patients at high risk of VTE. |

抄録 | The prevalence of preoperative deep vein thrombosis (DVT) has been reported to be relatively high in patients undergoing total hip arthroplasty. We investigated the prevalence of DVT, the association between hip function and preoperative DVT, and the effect of a history of surgery in patients who underwent primary total hip arthroplasty. We retrospectively analyzed the cases of the patients who underwent primary total hip arthroplasty between April 2013 and February 2020 at our institution. We evaluated the prevalence of preoperative DVT based on the results of the patients’ ultrasound screening. We performed univariate and multivariate analyses to investigate the association between the incidence of DVT and patient factors including age, sex, hip function, medical histories, and American Society of Anesthesiologists Physical Status classification. We analyzed 451 patients (494 hips). The prevalence of DVT was 14.2% (64 patients). The multivariate analysis demonstrated that increased age was an independent significant risk factor for DVT. The prevalence of preoperative DVT was relatively high among patients who underwent primary total hip arthroplasty. Preoperative DVT tended to be more prevalent in older patients. Hip function was not associated with the incidence of DVT. |

抄録 | Systemic lupus erythematosus (SLE) is a potentially fatal systemic autoimmune disease, and its etiology involves both genetic and environmental factors such as sex hormone imbalance, genetic predisposition, epigenetic regulation, and immunological factors. Dysregulation of microRNA (miRNA) is suggested to be one of the epigenetic factors in SLE. miRNA is a 22-nucleotide single-stranded noncoding RNA that contributes to post-transcriptional modulation of gene expression. miRNA targeting therapy has been suggested to be useful for the treatment of cancers and other diseases. Gene knockout and miRNA targeting therapy have been demonstrated to improve SLE disease activity in mice. However, these approaches have not yet reached the level of clinical application. miRNA targeting therapy is limited by the fact that each miRNA has multiple targets. In addition, the expression of certain miRNAs may differ among cell tissues within a single SLE patient. This limitation can be overcome by targeted delivery and chemical modifications. In the future, further research into miRNA chemical modifications and delivery systems will help us develop novel therapeutic agents for SLE. |

抄録 | The clinical benefit of perospirone for treatment of delirium in patients with advanced cancer is not sufficiently clear. The objective of this study was to compare the safety and effectiveness of perospirone to those of risperidone for the treatment of delirium in patients with advanced cancer. This is a secondary analysis of a multicenter prospective observational study in nine psycho-oncology consultation services in Japan. The study used the Delirium Rating Scale (DRS) Revised-98 to measure effectiveness and the CTCAE (Common Terminology Criteria for Adverse Events) version 4 to assess safety. Data from 16 patients who received perospirone and 53 patients who received risperidone were analyzed. The mean age was 70 years in the perospirone group and 73 years in the risperidone group. Both groups showed a significant decrease in the total score of DRS-R-98 after three days of treatment (perospirone: 11.7 (7.9-15.4) to 7.0 (3.3-10.7), difference −4.7, effect size=0.72, p=0.003; risperidone: 15.5 (13.6-17.4) to 12.2 (10.1-14.2), difference −3.3, effect size=0.55, p=0.00). The risperidone group showed significant improvements in sleep-wake cycle disturbance, orientation, attention, and visuospatial ability. In the perospirone group, there was a significant improvement of sleep-wake cycle disturbance. The median daily dose of perospirone was 4 mg/day. There were fewer episodes of somnolence as an adverse event in the perospirone group. Low-dose perospirone was thus found to be effective for the treatment of delirium in patients with advanced cancer and may be associated with fewer episodes of over-sedation as an adverse event. |

抄録 | We analyzed the treatment effects of chidamide and decitabine in combination with a HAG (homoharringtonine, cytarabine, G-CSF) priming regimen (CDHAG) in acute myeloid leukemia (AML) patients with TP53 mutation. Seven TP53 mutated AML patients were treated with CDHAG. The treatment effects were assessed using hemogram detection and bone marrow aspirate. The possible side effects were evaluated based on both hematological and non-hematological toxicity. Four of the seven patients were classified as having achieved complete remission after CDHAG treatment; one patient was considered to have achieved partial remission, and the remaining two patients were considered in non-remission. The overall response rate (ORR) to CDHAG was 71.4%. Regarding the side effects, the hematological toxicity level of the seven patients ranged from level III to level IV, and infections that occurred at lung, blood, and skin were recorded. Nausea, vomiting, liver injury, and kidney injury were also detected. However, all side effects were attenuated by proper management. The CDHAG regimen clearly improved the ORR (71.4%) of TP53-mutated AML patients, with no severe side effects. |

抄録 | Targeted therapies for malignant melanoma have improved patients’ prognoses. A primary gastrointestinal malignant melanoma is very rare, with no standard treatment strategy. We treated a 78-year-old Japanese female with advanced primary gastrointestinal melanoma of the descending colon and gallbladder. We administered a multidisciplinary treatment: surgical resection of the descending colon and gallbladder tumors, resection of the metastatic lymph nodes behind the pancreas head, and immune checkpoint antibody-blockade therapy (nivolumab) for ~4 years. PET/CT demonstrated no recurrent lesion for > 3 years. Multidisciplinary therapies (e.g., surgery, chemotherapy, radiotherapy, target therapy, and immune checkpoint antibody-blockade therapy) can successfully treat primary gastrointestinal malignant melanoma. |

抄録 | To clarify the relevance of prolactin (PRL) to clinical parameters in patients who visited our general medicine department, medical records of 353 patients in whom serum PRL levels were measured during the period from 2016 to 2018 were retrospectively reviewed. Data for 140 patients (M/F: 42/98) were analyzed after excluding patients lacking detailed records and patients taking dopaminergic agents. Median serum PRL levels were significantly lower in males than females: 6.5 ng/ml (IQR: 4.2-10.3) versus 8.1 ng/ml (5.9-12.9), respectively. Pain and general fatigue were the major symptoms at the first visit, and past histories of hypertension and dyslipidemia were frequent. Male patients with relatively high PRL levels (≥ 10 ng/ml) had significantly lower levels of serum albumin and significantly higher levels of serum LDH than those with low PRL (< 10 ng/ml). There were significant correlations of male PRL level with the erythrocyte sedimentation rate (R=0.62), serum LDH level (R=0.39) and serum albumin level (R=−0.52), while the level of serum CRP (R=0.33) showed an insignificant but weak positive correlation with PRL level. Collectively, these results show that PRL levels had gender-specific relevance to various clinical factors, with PRL levels in males being significantly related to inflammatory status. |

抄録 | A 65-year-old Japanese woman developed vesicular eruptions on her right ear due to varicella zoster virus (VZV) reactivation, followed by cranial polyneuritis and meningitis affecting her right cranial nerves V, VII, VIII, IX, and X. After acyclovir administration, her facial paralysis worsened. Intravenous methylprednisolone and vitamin C were administered on Day 4 post-admission. Her symptoms steadily improved, and by Day 45 she had fully recovered. Cranial polyneuritis is a rare complication of VZV reactivation, and there is no established method of treatment. This is the first report of full recovery from cranial polyneuritis using intravenous vitamin C as ancillary treatment. |

抄録 | Heart diseases are one of the major causes of morbidity and mortality worldwide. Despite major advances in drug and interventional therapies, surgical procedures, and organ transplantation, further research into new therapeutic options is still necessary. Stem cell therapy has emerged as one option for the treatment of a variety of heart diseases. Although a large number of clinical trials have shown stem cell therapy to be a promising therapeutic approach, the results obtained from these clinical studies are inconsistent, and stem cell-based improvements of heart performance and cardiac remodeling were found to be quite limited. Since the precise mechanisms underlying the therapeutic actions of stem cells are still under debate, researchers have developed a variety of strategies to improve and boost the potency of stem cells in repair. In this review, we summarize both the current therapeutic strategies using stem cells and future directions for enhancing stem cell potency. |
