    One of the important end-use performance measures of fabrics and other textile products is the handle, which measures the quality of fabrics as evaluated by reactions obtained not only tactilely but also visually. The well-known Kawabata Evaluation System includes both an objective evaluation and a prediction method of the handle. However, objective evaluations of the handle based on a visual perception of fabric aesthetics have not been investigated systematically. Thus, as the first step of a systematic study, we attempted to carry out a sensory evaluation of fabric aesthetics by experts on textile and untrained consumers using worsted and spun silk woven fabrics, which have different material effect and structural effect. Thereafter, the mean preference scores were examined by factor analysis to identify the principal factors of fabric aesthetics. From the result, it was found that two common factors-'luster and depth sensation' and 'surface roughness sensation'-were identified tentatively as the principal factors of fabric aesthetics.ArticleTEXTILE RESEARCH JOURNAL. 81(12):1216-1225 (2011)journal articl

    Evaluation of Urinary Stone Composition and Differentiation between Urinary Stones and Phleboliths Using Single-source Dual-energy Computed Tomography

    The aim of this study was to investigate the utility of single-source dual-energy computed tomography (SS-DECT) composition analysis in characterizing different types of urinary stones and differentiating them from phleboliths. This study included 29 patients with urinary stones who were scheduled for surgery. All patients were scanned, first using single-energy computed tomography acquisition and then DECT acquisition on SS-DECT. Dual-energy data were archived to a Gemstone spectral imaging (GSI) viewer (GE Healthcare, Milwaukee, WI, USA). Hounsfield units (HU) and effective atomic numbers (Zeff) were estimated using the GSI viewer. The results of dual-energy analysis were compared with the biochemical constitution of the stones. The chemical analysis determined that the stones included 32 calcium-based, 6 cystine and 1 struvite stone. Both HU and Zeff values were helpful in differentiating calcium-based stones from cystine and struvite stones and phleboliths. The Zeff values of phleboliths were significantly higher than those for struvite and cystine stones, whereas it was difficult to distinguish phleboliths from struvite and cystine stones using the HU values. Composition analysis using SS-DECT is helpful for distinguishing urinary stone types and discriminating phleboliths from urinary stones. Zeff values may be more useful than HU values for differentiating urinary stones from phleboliths

    Factors Predicting Difficult Biliary Cannulation during Endoscopic Retrograde Cholangiopancreatography for Common Bile Duct Stones

    Background/Aims Difficult biliary cannulation is an important risk factor for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP). Therefore, this study aimed to identify the factors that predict difficult cannulation for common bile duct stones (CBDS) to reduce the risk for PEP. Methods This multicenter retrospective study included 1,406 consecutive patients with native papillae who underwent ERCP for CBDS. Factors predicting difficult cannulation for CBDS were identified using univariate and multivariate analyses. Results Univariate analysis showed that six factors significantly predicted difficult cannulation: ERCP performed by non-expert endoscopists, low-volume center, absence of acute cholangitis, normal serum bilirubin, intradiverticular papilla, and type of major duodenal papilla. Multivariate analysis identified ERCP performed by non-expert endoscopists (odds ratio [OR], 2.5; p<0.001), low-volume center (OR, 1.6; p<0.001), intradiverticular papilla (OR, 1.3; p=0.007), normal serum bilirubin (OR, 1.3; p=0.038), and absence of acute cholangitis (OR, 1.3; p=0.049) as factors significantly predicting difficult cannulation for CBDS. Conclusions Initial cannulation by an experienced endoscopist, early rescue cannulation, or early takeover by an experienced endoscopist should be considered when performing ERCP for CBDS in the presence of factors predicting difficult cannulation

    Clinical Efficacy and Safety of Sitafloxacin 200 mg Once Daily for Refractory Genitourinary Tract Infections

    The aim of this ongoing trial is to evaluate the clinical efficacy and safety of sitafloxacin (STFX) 200 mg once daily (QD) for 7 days in patients with refractory genitourinary tract infections, which include recurrent or complicated cystitis, complicated pyelonephritis, bacterial prostatitis, and epididymitis. The primary endpoint is the microbiological efficacy at 5-9 days after the last administration of STFX. Recruitment began in February 2021, and the target total sample size is 92 participants

    Estimating the Radiation Dose to the Fetus in Prophylactic Internal Iliac Artery Balloon Occlusion: Three Cases

    Get PDF
    Background. Although radiation exposure is of great concern to expecting patients, little information is available on the fetal radiation dose associated with prophylactic internal iliac artery balloon occlusion (IIABO). Here we estimated the fetal radiation dose associated with prophylactic IIABO in Caesarean section (CS). Cases. We report our experience with the IIABO procedure in three consecutive patients with suspected placenta previa/accreta. Fetal radiation dose measurements were conducted prior to each CS by using an anthropomorphic phantom. Based on the simulated value, we calculated the fetal radiation dose as the absorbed dose. We found that the fetal radiation doses ranged from 12.88 to 31.6 mGy. The fetal radiation dose during the prophylactic IIABOs did not exceed 50 mGy. Conclusion. The IIABO procedure could result in a very small increase in the risk of harmful effects to the fetus

    Two cesarean deliveries after hemi-hysterectomy due to gestational trophoblastic neoplasia

    Objective: Although uterine didelphys per se is not associated with an impaired ability to conceive, the association between uterine anomalies and gestational trophoblastic neoplasia (GTN) remains unclear. The management of chemotherapy-resistant GTN in women with uterine didelphys raises a new issue regarding whether to perform a hemi-hysterectomy. Case report: A 23-year-old, gravida 1, para 0 Japanese woman was referred with a failed intermittent cervical dilatation for hematometra. Four years previously, she developed a GTN Stage III, score 5. As two cycles of chemotherapy with methotrexate (MTX) and one cycle of EMA-CO (etoposide, MTX, actinomycin D, cyclophosphamide and vincristine) did not result in remission, we performed an abdominal hemi-hysterectomy. After a canalization procedure and cervicoplasty were performed, the patient conceived naturally and prematurely delivered by cesarean section twice. Conclusion: A hemi-hysterectomy should be considered for fertility preservation when GTN develops on either side of a didelphic uterus and adjuvant chemotherapy does not result in remission.
