After screening 16 isolates, was selected because its broad-spectrum antibacterial activity against many pathogens, such as Vibrio...
Objectives: This study aimed to compare ultrasound (US) findings between automated and handheld breast (ABUS HHUS, respectively) in small cancers, based on the imaging reporting data system (BI-RADS) category. Methods: We included 51 women (mean age: 52 years; range: 39-66 years) with cancer (invasive or DCIS), all of whom underwent both ABUS HHUS. Patients tumors measuring ≤1 cm either modality were enrolled. Two radiologists retrospectively evaluated multiple features, including shape,...
TERT promoter mutation is associated with poor prognosis in differentiated thyroid carcinoma, US features varying by status. However, this correlation anaplastic carcinoma (ATC) understudied. We investigated the association between clinicopathological characteristics and of ATC status prognosis. From November 1994 to May 2022, 58 nodules from patients were analyzed. Two radiologists retrospectively reviewed based on revised K-TIRADS ACR-TIRADS. Of all nodules, 32 tested for detected 11....
To compare the outcomes of imaging methods (mammography alone, ultrasound [US] mammography combined with US, and magnetic resonance [MRI]-based examination) for surveillance during first 5 years after breast cancer surgery. This retrospective cohort study analyzed medical records patients who underwent surgery at a single institution between January 2011 December 2015. Imaging was performed 6-month or 1-year intervals years. A total 6371 women (median age, 49 years; age range, 20-90 years)...
In this study, we aimed to evaluate the benefits and losses of mammography with without implant displacement (ID) propose an appropriate imaging protocol for screening breasts implants. We evaluated mammograms 162 in 96 patients including 71 biopsy-proven cancers. Mammography each breast included standard MLO ID images. reviewed using clinical image quality criteria, which consist parameters that proper positioning resolution. Standard images showed significantly higher scores but lower...
Although anaplastic thyroid carcinoma (ATC) is a fatal form of cancer with an overall survival only few months, there are some factors associated longer survival. However, it remains unknown whether asymptomatic ATC differs from symptomatic in terms characteristics and prognosis. Therefore, we aimed to examine the clinicopathological prognosis compared those ATC. We retrospectively reviewed medical records 113 patients who were registered at our institution between November 1994 July 2020. A...
This study aimed to evaluate the radiological and clinical characteristics of benign adenomyoepitheliomas breast.Over last 20 years, 120 patients were histologically diagnosed with breast adenomyoepithelioma (AME) at our institution. We excluded 43 who incidentally during mastectomy for cancer, 28 underwent percutaneous biopsy without further excision, 8 had biopsy-confirmed AME found have another pathology after complete excision. retrospectively reviewed records findings remaining 41 AMEs...
This study compared the malignancy risk of intermediate suspicion thyroid nodules according to presence suspicious ultrasonographic (US) findings.From January 2014 December 2014, 299 consecutive in 281 patients (mean age, 50.6±12.5 years) with final diagnoses were included this study. Two radiologists retrospectively reviewed US findings and subcategorized category into without findings, including punctate echogenic foci, nonparallel orientation, or irregular margins. The rates between two...
The macrofollicular subtype of papillary thyroid cancer (MFS-PTC) is a rare often leading to challenging diagnosis. To evaluate the ultrasonographic (US) features and clinical implication MFS-PTC. Records 14 patients histologically diagnosed with MFS-PTC at our institution over period 16 years were retrospectively reviewed. Preoperative US features, Bethesda categories determined by fine-needle aspiration (FNA) or core needle biopsy (CNB), final pathology assessed in all Of cases, most...
Malignant breast nonmass lesions were associated with calcifications, posterior shadowing, segmental distribution, and mixed echogenicity at screening US more often seen in women abnormal mammograms.
Cholangiocarcinoma has a poor prognosis and is refractory to conventional chemotherapy radiation therapy. Improving survival of patients with advanced cholangiocarcinoma urgently requires the development new effective targeted therapies in combination chemotherapy. We previously developed human monoclonal antibody (mAb) Ab417 that binds both mouse L1 cell adhesion molecule (L1CAM) high affinities. In present study, we observed exhibited tumor targeting ability biodistribution studies...
Rationale and Objective: To evaluate the characteristic clinical imaging findings of charcoal granuloma suggest features that may differentiate from breast cancer. Materials Methods: This retrospective study included 18 patients with a histologically confirmed between 2005 2021 at single institution. All had history surgery after ultrasound (US)-guided marking. Two radiologists analyzed radiologic granulomas, including presence mass or calcification; shape, margin density masses on...
We present our initial experience of ultrasound (US)-guided localization clipped metastatic axillary lymph nodes (LNs) following neoadjuvant chemotherapy (NAC). evaluated US visibility and the successful excision rate LN after NAC in 29 consecutive patients with breast cancer. US-guided was performed 22 on day surgery, while seven underwent surgery without localization. The clips were identified all residual LNs 6 12 (50%) US. Six visible at presumed previous clip insertion site. 100% (even...
The prevalence of the tall cell variant papillary thyroid carcinoma (TCVPTC), which has a poor prognosis, increased as its definition been modified. We sought to investigate whether TCVPTC is different from classic type on ultrasonography (US).
