    In: AATCC Journal of Research, SAGE Publications, Vol. 6, No. 1_suppl ( 2019-05), p. 28-32
    Abstract: Para-aramid fiber was fibrillated in a dimethyl sulfoxide (DMSO)/tetrabutylammonium fluoride (TBAF) solution at 80 °C. Physical gelation of the dispersion liquid occurred by cooling to 20 °C at varying rates of 0.5 to 2.8 °C/min. The solvent was then replaced with acetone and the gel was dried by supercritical CO 2 to obtain an aerogel. The fibril diameter decreased from ∼40 nm to 20 nm using a TBAF/DMSO ratio of 1:22 to 2:11, respectively. The specific surface area (SSA) of aerogel reached 702 m 2 /g at a fibril diameter of 20 nm. Prepared aerogel fiber with a diameter of 536 μm had a translucent appearance, an SSA of 473 m 2 /g, and a low density of 0.067 g/cm 3 . It bent freely and repeatedly without deformation or breaking.

    In: Annals of Otology, Rhinology & Laryngology, SAGE Publications, Vol. 124, No. 2 ( 2015-02), p. 162-167
    Abstract: The first objective was to describe a novel case of migration of a broken dental needle into the parapharyngeal space. The second was to address the importance of simulation elucidating visualization of such a thin needle under X-ray fluoroscopy. Methods: Clinical case records (including computed tomography [CT] and surgical approaches) were reviewed, and a simulation experiment using a head phantom was conducted using the same settings applied intraoperatively. Results: A 36-year-old man was referred after failure to locate a broken 31-G dental needle. Computed tomography revealed migration of the needle into the parapharyngeal space. Intraoperative X-ray fluoroscopy failed to identify the needle, so a steel wire was applied as a reference during X-ray to locate the foreign body. The needle was successfully removed using an intraoral approach with tonsillectomy under surgical microscopy. The simulation showed that the dental needle was able to be identified only after applying an appropriate compensating filter, contrasting with the steel wire. Conclusion: Meticulous preoperative simulation regarding visual identification of dental needle foreign bodies is mandatory. Intraoperative radiography and an intraoral approach with tonsillectomy under surgical microscopy offer benefits for accessing the parapharyngeal space, specifically for cases medial to the great vessels.

    Abstract: Incidence and predictors of ischemic stroke in patients with transient ischemic attack (TIA) have not been fully clarified outside Europe and North America. Aims We undertook the present prospective, multicenter study to clarify the incidence, predictors, and etiology of ischemic stroke within one year of TIA onset in Japan. Methods The study subjects were patients within seven days of TIA onset who were enrolled in a prospective register from 57 hospitals between June 2011 and December 2013. The primary endpoint was occurrence of ischemic stroke. Results Of 1365 consecutive patients, 1245 were followed for one year after TIA onset; 101 (8.1%) experienced ischemic stroke during follow-up. The leading subtype of ischemic stroke was small-vessel occlusion (SVO) followed by large-artery atherosclerosis (LAA) attributable to intracranial artery diseases. When dividing ischemic stroke events between those occurring within the first 90 days after TIA onset and those occurring after the first 90 days, the leading subtype of ischemic stroke within the first 90 days after TIA onset was SVO, followed by LAA attributable to intracranial artery diseases. In comparison, the subtypes most commonly seen beyond the first 90 days after TIA onset were cardioembolic and LAA attributable to intracranial artery disease. The one-year risk of ischemic stroke increased significantly as ABCD 2 score increased, at 6.2% for 0–3 points, 7.2% for 4–5 points, and 11.6% for 6–7 points. Conclusions The one-year ischemic stroke risk after TIA was about 8% and was associated with the ABCD 2 score. The most common subtype of subsequent ischemic stroke was SVO.

    Abstract: The mechanism(s) of myocardial ischemia in hypertrophic cardiomyopathy remain unclear. In this report, the authors present a 75-year-old Japanese woman with nonob structive hypertrophic cardiomyopathy in whom paroxysmal atrial fibrillation caused severe myocardial ischemia and induced sustained ventricular tachycardia. Her coronary angiogram showed normal findings, and no ischemic changes were provoked by either physical exercise testing or dobutamine stress echocardiography under sinus rhythm. In view of these findings, the rapid ventricular response in the absence of atrial contraction may aggravate or induce myocardial ischemia and predispose patients with hypertrophic cardiomyopathy to develop lethal ventricular arrhythmia.

    In: Therapeutic Advances in Neurological Disorders, SAGE Publications, Vol. 13 ( 2020-01), p. 175628642090420-
    Abstract: Eculizumab is a humanized monoclonal antibody that targets complement protein C5 and inhibits terminal complement-mediated damage at the neuromuscular junction. Recently, the REGAIN study showed that eculizumab was effective and well tolerated in patients with anti-acetylcholine receptor antibody-positive refractory generalized myasthenia gravis (gMG). However, there is no consensus regarding which kind of patients with gMG are selected to preferentially receive eculizumab. Methods: Between January and December 2018, we followed 1388 patients with MG at seven hospitals located in Tokyo and Chiba. We evaluated the clinical features of MG and the patients’ quality of life. Clinical status and severity were determined by the recommendations of the Myasthenia Gravis Foundation of America. Results: Of 1388 patients with MG, 12 (0.9%) patients received eculizumab. A total of 11 patients who were anti-acetylcholine receptor antibody-positive with refractory gMG (M:F = 3:8) completed the 26-week treatment with eculizumab. The disease subtypes represented included five cases of early onset MG, one of late-onset MG, and five of thymoma-associated MG. Overall, seven patients had experienced myasthenic crisis. The mean quantitative MG score ranged from 18.6 at baseline to 9.1 at week 26 ( p = 0.008). Similarly, the mean MG activities of daily living score ranged from 10.8 at baseline to 4.2 at week 26 ( p = 0.002). There were marked improvements in all patients’ quality of life status. Overall, seven patients were able to reduce the dose of prednisolone at week 26. All but one patient did not require additional rescue treatment. Overall, one patient with early onset MG could not continue the eculizumab treatment due to nausea and vertigo. Conclusion: We demonstrate that eculizumab provided remarkable benefits for refractory gMG in practical real-world experience as well as in the REGAIN study. Patients with refractory gMG with myasthenia crisis and thymoma-associated MG are suitable for eculizumab administration.

    Abstract: Carcinosarcoma of the upper urinary tract is very rare. In this article, we report a case of upper urinary tract carcinosarcoma with rhabdomyoblastic differentiation showing distinct transition between the epithelial and mesenchymal components confirmed by morphology and immunohistochemistry. An 81-year-old female underwent radical nephroureterectomy under the diagnosis of left ureteral urothelial carcinoma (UC). Multiple invasive tumors showed combined histology with UC and rhabdomyosarcomatous elements (pT2-ureter and pT3-renal pelvis, pN0, u-lt0, ly0, v0, RM0). Each element demonstrated typical epithelial or mesenchymal staining patterns (positive for AE1/AE3 in the former and positive for vimentin and myogenin in the latter). Notably, immunohistochemical transition patterns of GATA-3, p63, SOX2, and myogenin between UC and rhabdomyosarcomatous elements were observed, implying possible involvement of neoplastic stem cells in the process of carcinosarcoma formation. The patient did not receive any adjuvant therapy and eventually succumbed to multiple visceral metastases (lungs and liver) at 11 months postoperatively. No autopsy was performed.

    Abstract: Recent prospective registration studies of transient ischemic attack in Western countries demonstrated that large artery atherosclerosis is the highest risk etiology for early stroke recurrence under urgent evaluation and treatment. On the other hand, some limited transient ischemic attack studies from East Asian countries showed transient ischemic attack patients due to small vessel occlusion were at a higher early stroke risk. Aims We aimed to assess the risk for early stroke in small vessel occlusion-transient ischemic attack patients in a Japanese large transient ischemic attack registry. Methods We analyzed the data of a prospective Japanese transient ischemic attack registry including 1320 transient ischemic attack patients within seven days after onset. Small vessel occlusion-transient ischemic attack was defined as the presence of lacunar transient ischemic attack syndrome, without other etiologies. The outcome measure was recurrent stroke within 30 days after transient ischemic attack. The predictors of 30-day recurrent stroke were estimated using the Cox proportional hazards model. Results The study population had a mean age of 69 ± 12 years and 470 were women. Recurrent stroke was observed in 61 patients (4.6%), and the highest rate was observed with small vessel occlusion-transient ischemic attack (7.8%), followed by large artery atherosclerosis (5.4%). In multivariate analysis, recurrent stroke was independently associated with small vessel occlusion-transient ischemic attack (hazard ratio (HR): 2.01, 95% confidence interval (CI): 1.19–3.35), higher systolic blood pressure (HR: 1.18, 95% CI: 1.08–1.28), and presentation within 3 h after onset (HR: 2.21, 95% CI: 1.27–4.04). Furthermore, small vessel occlusion-transient ischemic attack with acute small deep infarct on diffusion-weighted imaging was a stronger predictor of recurrent stroke (HR: 4.87, 95% CI: 2.09–10.0). Conclusion Small vessel occlusion-transient ischemic attack, especially with acute small deep infarct, had a higher early stroke risk compared with other etiologies in Japanese transient ischemic attack patients who received early management.
