13. Use of n-butyl-2-cyanoacrylate for microvascular decompression in a Jehovah's witness patient.

Abstract

Objective: We report the application of n-butyl-2-cyanoacrylate (n-BCA) in microvascular decompression (MVD) surgery for a Jehovah's Witness patient. To our best knowledge, this is the first case wherein n-BCA has been employed as an adhesive to the offending artery. Case presentation: A 55-year-old female Jehovah's Witness patient was suffering from serious right hemifacial spasm. Although MVD surgery was needed, the patient resisted any curative medical treatment involving the application of whole blood products, including fibrin glue. Thus, we proposed several choices using artificial materials, including n-BCA as an adhesive, and received informed consent from the patient. Result: MVD was performed on the dolichoectatic right vertebral artery and right posterior inferior cerebellar artery. The abnormal vessel response disappeared during the procedure and transposition using n-BCA of the concerned vessels was successful. The patient experienced a favorable postoperative clinical course and has been free from the spasm for a year. No abnormal findings were detected in the radiological examination during the follow-up period. Conclusion: Although careful follow-up is mandatory, n-BCA is a possible alternative option in MVD surgery. [ABSTRACT FROM AUTHOR]

Abstract

We developed three e-learning systems for endoscopists to acquire the necessary skills to improve the diagnosis of early gastric cancer (EGC) and demonstrated their usefulness using randomized controlled trials. The subjects of the three e-learning systems were "detection", "characterization", and "preoperative assessment". The contents of each e-learning system included "technique", "knowledge", and "obtaining experience". All e-learning systems proved useful for endoscopists to learn how to diagnose EGC. Lecture videos describing "the technique" and "the knowledge" can be beneficial. In addition, repeating 100 self-study cases allows learners to gain "experience" and improve their diagnostic skills further. Web-based e-learning systems have more advantages than other teaching methods because the number of participants is unlimited. Histopathological diagnosis is the gold standard for the diagnosis of gastric cancer. Therefore, we developed a comprehensive diagnostic algorithm to standardize the histopathological diagnosis of gastric cancer. Once we have successfully shown that this algorithm is helpful for the accurate histopathological diagnosis of cancer, we will complete a series of e-learning systems designed to assess EGC accurately.

Subjects

Abstract

Objectives: Methotrexate (MTX) is associated with extensive side effects, including myelosuppression, interstitial pneumonia, and infection. It is, therefore, critical to establish whether its administration is required after achieving remission with tocilizumab (TCZ) and MTX combination therapy in patients with rheumatoid arthritis (RA). Therefore, the aim of this multicenter, observational, cohort study was to evaluate the feasibility of MTX discontinuation for the safety of these patients. Methods: Patients with RA were administered TCZ, with or without MTX, for 3 years; those who received TCZ+MTX combination therapy were selected. After remission was achieved, MTX was discontinued without flare development in one group (discontinued [DISC] group, n = 33) and continued without flare development in another group (maintain [MAIN] group, n = 37). The clinical efficacy of TCZ+MTX therapy, patient background characteristics, and adverse events were compared between groups. Results: The disease activity score in 28 joints-erythrocyte sedimentation rate (DAS28-ESR) at 3, 6, and 9 months was significantly lower in the DISC group (P < .05, P < .01, and P < .01, respectively). Further, the DAS28-ESR remission rate at 6 and 9 months and Boolean remission rate at 6 months were significantly higher in the DISC group (P < .01 for all). Disease duration was significantly longer in the DISC group (P < .05). Furthermore, the number of patients with stage 4 RA was significantly higher in the DISC group (P < .01). Conclusions: Once remission was achieved, MTX was discontinued in patients who responded favorably to TCZ+MTX therapy, despite the prolonged disease duration and stage progression.

37. Rosai–Dorfman disease differentiated from a posterior mediastinal tumour: a case report.

Abstract

Rosai–Dorfman disease presenting solely with intrathoracic lesions is exceptionally rare. Herein, we report the case of a 53-year-old man presenting with a posterior mediastinal tumour. Computed tomography revealed a 7-cm soft tissue shadow in the posterior mediastinum. Positron emission tomography-computed tomography demonstrated a high maximum standardized uptake value of 10.35 in the tumour, with no evidence of lymph node or other organ involvement. Serum marker levels were within the normal range. Thoracoscopic surgery was performed to obtain a biopsy for a definitive diagnosis and treatment planning. Postoperative histological findings revealed a diffuse infiltration of eosinophilic histiocytes, lymphocytes, and plasma cells. Immunohistochemical analysis indicated positivity for S-100 protein, oct-2, and cyclin D1 in these histiocytes. Consequently, the patient was diagnosed with Rosai–Dorfman disease and is currently asymptomatic, undergoing regular monitoring without treatment as an outpatient. The absence of characteristic findings, such as bilateral cervical lymphadenopathy, posed challenges in preoperative diagnosis. [ABSTRACT FROM AUTHOR]

Abstract

形式名詞「うち」は時間的意味や人称的意味などの様々な意味を表す多義語である。「うち」のこのような多様な意味の相互関係、すなわち意味ネットワークを明らかにすることが本稿の目的である。先ず、「うち」のプロトタイプ的意味として〈ある空間の区切られた境界の中〉を抽出した。次に、スキーマ的意味を〈境界の中〉とする仮説を立てた。「うち」が意味拡張を起こす対象を〈人〉、〈区分を持つもの〉、〈時間〉に大別し、それぞれへのメタファーを介した意味拡張、及びそれぞれの領域内でのイメージ・スキーマ変換またはメトニミーを通したスキーマ的意味の精緻化とその結果として生じた多様な意味について考察した。更に、各意味に対する分析を通してスキーマ的意味についての仮説を検証し、最後に、各意味の相互関係を意味ネットワークとして提示した。, The purpose of this study is to reveal the network of the various meanings of the Japanese abstract noun uchi. Since uchi prototypically denotes that the referent is inside a certain bounded area of space, it can be conceived as an expression of ‘inside a container’. It’s schematic meaning ‘inside the boundaries’ extends to various expressions of enclosures. First, it metaphorically extends to houses and then via image-schema transformation to its contents, i.e., the residents. Thereby, uchi acquires a pronominal first-person usage (especially when used plurally) and meanings such as ‘family’ and ‘spouse’. It is well-known as an expression of the in-group. Through image schemas center-periphery and near-far, it extends into social in-groups such as affiliated institutes to which ‘I’ belong, thereby expressing various degrees of affiliation and social distance. Uchi metaphorically extends to parts of various masses and categories. Furthermore, it extends to temporal constructions to produce various expressions denoting temporal conditions, durations, etc. This variation is brought forth by different focusing patterns of the boundary.
