子宮内膜症関連卵巣癌と隆起性病変を有する良性卵巣内膜症を鑑別する因子の検討

PURPOSE: Mural nodules and papillary projections can be seen in benign ovarian endometriosis (OE) and malignant transformation of OE (endometriosis-associated ovarian cancer [EAOC]), which can pose a challenging diagnostic dilemma to clinicians. We identify the preoperative imaging characteristics helpful to the differential diagnosis between benign OE with mural nodules and EAOC. MATERIALS AND METHODS: This was a retrospective study of 82 patients who were diagnosed pathologically to have OE with mural nodules (n = 42) and malignant transformations of these tumors (n = 40) at the Nara Medical University Hospital from January 2008 to January 2015. All patients were assessed with contrast-enhanced magnetic resonance imaging (MRI) before surgery. Patient demographics, and clinical and pathologic features were analyzed to detect the significant differences between the two groups. RESULTS: Histological examinations of resected OE tissue specimens revealed that a majority (78.6%) of the mural nodular lesions were retracted blood clots. We found that the patients with malignant mural nodules, when compared to those with benign nodules, were older, had larger cyst diameters and larger mural nodule sizes, and were more likely to exhibit a taller than wider lesion. They were also more likely to present with various signal intensities on T1-weighted images (T1WI), high-signal intensity on T2-weighted images (T2WI), a lower proportion of shading on T2WI, and were more likely to show an anterior location of the cyst. In the multivariate logistic regression analysis, "Height" (>1.5 cm) and "Height-Width ratio (HWR)" (>0.9) of mural nodules, maximum diameter of the cyst (>7.9 cm), and age at diagnosis (>43 years) were independent predictors to distinguish EAOC from OE with mural nodules. CONCLUSION: The "Height" and "HWR" of the mural nodules in the cyst may yield a novel potential diagnostic factor for differentiating EAOC from benign OE with mural nodules.博士（医学）・乙第1415号・平成30年3月15日©2017 Japanese Society for Magnetic Resonance in Medicine This work is licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives International License. https://creativecommons.org/licenses/by-nc-nd/4.0/

日本版クライエントと作業療法士の協業関係尺度の試作版開発

Abstract Introduction. The success of a client-centred practice depends on the relationship between the client and therapist, and their ability to make constructive decisions together, particularly in the field of occupational therapy. The aim of this study was to develop a Collaborative Relationship Scale (OTCRS) to measure the quality of such interaction. Materials and Methods. This effort included constructing a draft questionnaire and testing its validity and reliability. A Rasch analysis was applied to determine validity, and several tests were used to confirm its internal consistency. Results. After reviewing over 130 scientific papers and books, we built explicit selection criteria for issues to be addressed in this instrument, and we developed 40 questions to be included. These were analysed using a standard content validation process and a Rasch analysis to examine confirmation validity. A nine-item scale was finalised for testing(OTCRS-9). This review process revealed OTCRS-9’s validity, high internal consistency and item/person separation reliability. Conclusion. This study presents only the initial phase of scale development. As suggested by COnsensus-based Standards for the selection of health Measurement Instruments(COSMIN), the OTCRS-9 score should be tested further for validity and reliability and should also be conducted in other ethnicities to improve its generalizability.東京都立大学学位論文甲第1069号副論

Carcinosarcoma of the Uterine Corpus with Alpha-Fetoprotein-Producing Hepatoid Adenocarcinoma: A Report of Two Cases

We report two cases of uterine carcinosarcoma associated with alpha-fetoprotein (AFP)-producing hepatoid adenocarcinoma. Samples were obtained from two women aged 63 and 82 years. Serum AFP levels of the two samples were 10,131 and 401 ng/ml, respectively. Histologically, in both cases the tumor cells were composed of hepatoid adenocarcinoma component and sarcoma component including rhabdomyosarcoma. Immunohistochemical analyses revealed that AFP was expressed in the cytoplasm of the carcinomatous component. After surgery, the patients received six courses of carboplatin/paclitaxel chemotherapy, and the serum levels of AFP decreased to normal range. The first patient is alive and well at the 2-year follow-up, while the second patient died of disease 1 year after initial operative treatment. This is, to our knowledge, the second report of carcinosarcoma of the uterine corpus with AFP-producing hepatoid adenocarcinoma, as proven by immunohistochemical analyses

Protective effects of cold spinoplegia with fasudil against ischemic spinal cord injury in rabbits

ObjectiveParaplegia remains a serious complication after surgical repair of thoracoabdominal aortic aneurysms. The aim of this study was to evaluate the neuroprotective efficacy of fasudil, a Rho kinase (ROCK) inhibitor, by reducing the number of infiltrating cells in the ventral horn and increasing the induction of eNOS against ischemic spinal cord injury in rabbits.MethodsEighteen Japanese white rabbits were divided into three groups: saline (group 1, n = 7, 4°C) and fasudil (group 2, n = 6, 4°C) were immediately infused into the isolated segmental lumbar arteries over 30 seconds after aortic clamping. Group 3 (n = 5) was the sham-operated group. Hind limb function was evaluated 4 and 8 hours, and 1 and 2 days after 15 minutes of transient ischemia. Cell damage was analyzed by hematoxylin and eosin staining and temporal profiles of endothelial nitric oxide synthase immunoreactivity were performed. The number of intact motor neuron cells and infiltrating cells in the ventral horn were compared.ResultsTwo days after reperfusion, group 2 and group 3 showed better neurologic function, a greater number of intact motor neuron cells, and a smaller number of infiltrating cells in the ventral horn than group 1. The induction of endothelial nitric oxide synthase (eNOS) was prolonged up to 2 days after reperfusion in group 2.ConclusionThese results indicate that fasudil has neuroprotective effects against ischemic spinal cord injury in rabbits by reducing the number of infiltrating cells in the ventral horn and prolonging the expression of eNOS.Clinical RelevanceParaplegia or paralysis caused by spinal cord ischemia remains a devastating and unpredictable complication after descending and thoracoabdominal aortic surgery. This study has revealed that fasudil has a neuroprotective effect against ischemic spinal cord injury in rabbits. Inhibition of the Rho/Rho kinase pathway by fasudil reduces the number of infiltrating cells in the ventral horn and prolongs the expression of eNOS. In the near future, Rho kinase may be an important therapeutic target for paraplegia induced by spinal cord ischemia

卵巣明細胞癌と類内膜癌の鑑別に関するMRIについての知見

BACKGROUND: Common cancerous histological types associated with endometriosis are clear cell carcinoma (CCC) and endometrioid carcinoma (EC). CCC is regarded as an aggressive, chemoresistant histological subtype. Magnetic resonance imaging (MRI) offers some potential advantages to diagnose ovarian tumors compared with ultrasonography or computed tomography. This study aimed to identify MRI features that can be used to differentiate between CCC and EC. METHODS: We searched medical records of patients with ovarian cancers who underwent surgical treatment at Nara Medical University Hospital between January 2008 and September 2018; we identified 98 patients with CCC or EC who had undergone preoperative MRI. Contrasted MRI scans were performed less than 2 months before surgery. Patients were excluded from the study if they had no pathology, other pathological subtype of epithelial ovarian cancer, and/or salvage treatment for recurrence and metastatic ovarian cancer at the time of study initiation. Clinically relevant variables that were statistically significant by univariate analysis were selected for subsequent multivariate regression analysis to identify independent factors to distinguish CCC from EC. RESULTS: MRI of CCC and EC showed a large cystic heterogeneous mixed mass with mural nodules protruding into the cystic space. Univariate logistic regression analysis revealed that the growth pattern (broad-based nodular structures [multifocal/concentric sign] or polypoid structures [focal/eccentric sign]), surface irregularity (a smooth/regular surface or a rough/irregular/lobulated surface), "Width" of mural nodule, "Height-to-Width" ratio (HWR), and presence of preoperative ascites were factors that significantly differed between CCC and EC. In the multivariate logistic regression analysis, the growth pattern of the mural nodule (odds ratio [OR] = 0.69, 95% confidence interval [CI]: 0.013-0.273, p = 0.0004) and the HWR (OR = 3.71, 95% CI: 1.128-13.438, p = 0.036) were independent predictors to distinguish CCC from EC. CONCLUSIONS: In conclusion, MRI data showed that the growth pattern of mural nodules and the HWR were independent factors that could allow differentiation between CCC and EC. This finding may be helpful to predict patient prognosis before operation.博士（医学）・乙第1433号・令和元年9月27日© The Author(s). 2019 Open Access This article is distributed under the terms of the Creative Commons Attribution 4.0 International License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.
