    Abstract Introduction: Parosteal osteosarcomas are low-grade bony malignancies that are treated primarily with surgical resection and reconstruction. This report discusses a unique case of a pediatric patient who presented with a parosteal osteosarcoma of the distal radius causing extensive erosive mass effect and growth disturbance of the adjacent ulna. Likely due to their slow-growing nonaggressive nature, parosteal osteosarcomas have not been previously described to abut adjacent bony structures through direct contact. The patient presented in a significantly delayed manner due to social circumstances, inadvertently revealing this novel behavior. This report reviews this rare case and describes the current understanding of this tumor.
    Case presentation: The patient is a 13-year-old male who presented with a parosteal osteosarcoma of his distal radius. He presented with a palpable wrist mass and wrist stiffness. He presented in a delayed manner with advanced local disease due to social factors. Imaging revealed an osseous radial mass that abutted the ulna and likely stunted its growth. The patient ultimately underwent complex resection and allograft reconstruction of both his distal radius and ulna. Intraoperative pathology was confirmed to have negative tumor margins. Allograft reconstruction of the radius and ulna was performed utilizing patient-specific custom cutting guides. At the 6-month postoperative visit, the patient had no recurrence of the mass, minimal pain, and had almost regained range of motion of the extremities. Clinical radiographs at the 6-month postoperative visit demonstrated allograft incorporation.
    Conclusions: A previously unreported case of pediatric parosteal osteosarcoma of the distal radius with erosion of the adjacent ulna through direct contact is presented. The challenges in and the importance of arriving at a definitive diagnosis in a timely manner for the proper treatment of this malignancy are emphasized.

    Abstract Purpose: The objective of this study was to describe and analyze the clinicopathological features of primary choriocarcinoma (PCC) observed in male patients treated at the Samsung Medical Center between 1996 and 2020.
    Materials and methods: We reviewed the clinical records of 14 male patients with PCC retrospectively to assess their demographic, histological, and clinical characteristics at the time of diagnosis as well as identify the treatment outcomes.
    Results: The median age of the patients was 33 years. The primary tumor site was the testicles in seven cases (50%), the mediastinum in six cases (43%), and the brain in one case (7%). The most common metastatic site was the lungs (79%), followed by the brain (43%). All patients with PCC received cytotoxic chemotherapy. Twelve patients had records of their response to cytotoxic chemotherapy; of these 12 patients, eight (8/12, 67%) achieved an objective response, and four (4/12, 33%) achieved stable disease response as the best response during chemotherapy.
    Conclusion: It is known that most male PCC patients eventually develop resistance to cytotoxic chemotherapy and die. Factors such as poor response to chemotherapy, high disease burden, brain metastasis, and hemoptysis at the time of diagnosis are associated with shorter survival time in male PCC patients. Programmed death-1/programmed death-ligand 1 blockade therapy can be a salvage treatment for chemotherapy-resistant male PCC patients.

    Abstract Treatment of metastatic urothelial carcinoma (mUC) after failure with platinum-based chemotherapy and immune checkpoint inhibitors (ICIs) remains controversial. To explore the role of subsequent systemic therapy, medical records from 436 patients who were consecutively treated with chemotherapy for mUC between May 2017 and April 2021 were collected from a single-center cancer registry. The primary endpoint was overall survival (OS), and progression-free survival (PFS) and response rate (RR) were also assessed. Among the 318 patients who failed both platinum and ICIs, subsequent therapy was delivered to 166 (52%) patients: taxanes (

    Abstract Purpose: The aim of this retrospective study was to evaluate the efficacy of adjuvant cisplatin-based chemotherapy in patients with locally-advanced upper tract urothelial carcinoma (UTUC), administered following radical nephroureterectomy.
    Materials and methods: Patients with UTUC, arising from renal pelvis or ureter, staged pT3/T4 or N+ were treated with adjuvant chemotherapy following surgery. The chemotherapy consisted of gemcitabine 1,000 mg/m2 on days 1 and 8, cisplatin 70 mg/m2 on day 1. Treatment was repeated every 3 weeks for up to 4 cycles. Endpoints included disease-free survival (DFS), metastasis-free survival (MFS), and safety.
    Results: Among 89 eligible patients, 85 (96%) completed at least 3 cycles of adjuvant chemotherapy. Chemotherapy was well tolerated, the main toxicities being mild-to-moderate gastrointestinal toxic effects and pruritus. With a median follow-up of 37 months, median DFS was 30 months (95% CI, 22 to 39), and the median MFS was not reached. The 3-year DFS and MFS were 44% and 56%, respectively. Multivariate analyses revealed that the main factor associated with DFS and MFS was the lymph node involvement, whereas age, T stage, grade, or the primary site of UTUC were not significantly associated with DFS or MFS.
    Conclusion: Adjuvant cisplatin-based chemotherapy after radical surgery of pT3/T4 or N+ UTUC was feasible and may demonstrate benefits in DFS and MFS. Whether novel agents added to the chemotherapy regimen, as a concurrent combination or maintenance, impacts on survival or reduces the development of metastases remains to be studied.

    Abstract In industry, recent research developments include flexible films and foldable films. The next step is the development of stretchable films, and studies are being intensively carried out. Research on the development of stretchable and transparent materials is also increasing greatly. Currently, polydimethylsiloxane (PDMS) is the most commonly used film in the industry. However, PDMS surfaces are hydrophobic, so their use is limited to making materials and compounds with hydrophilic properties. In this study, we developed a transparent polyurethane film that can be used for multiple purposes. A transparency comparison between the transparent polyurethane film and the general polyurethane film was used to verify their future application. The conventional polyurethane films showed a transmittance rate of 2.2 percent, but the transparent polyurethane films achieved a high transmittance rate of 85 percent. To determine whether the film can be realized, we produced a conductive paste using resin for the transparent polyurethane film. In addition, a conductive paste was made based on the material used in the transparent polyurethane film to verify the hardness and reliability of the adhesion of electrodes, and we confirmed this with thermogravimetric analysis (TGA). The transparent polyurethane based paste was made with stretchable electrodes through a screen printing method. The manufactured stretchable electrodes were demonstrated by mechanical and adhesion tests. Finally, a permittivity test was conducted to determine the suitability of the film for application to printed electrodes for antennas in the future. The genetic rate of transparent polyurethane films was better than that of conventional polyurethane films. Moreover, the adhesion of the transparent polyurethane film and stretchable electrodes was as good as that of conventional polyurethane film and stretchable electrodes, and observation by optical microscopy confirmed that the printing performance was also excellent. In addition, the conductive paste made based on the transparent polyurethane film material was cured for 1 hour at 120 °C, and TGA analysis confirmed that both the binders and curing agent responded well in the test for curing the developed stretchable electrodes and transparent polyurethane.

    Abstract This study compares the characteristics and low-temperature curing properties of pastes prepared from silver (Ag) powders synthesized by either wet powder (WP) or dry powder (DP) processing. The WP synthesis of electrode particles has the advantage of controlling the average particle size and particle size distribution but the disadvantage of producing low-purity, crystalline particles because they are synthesized through chemical reduction at less than 100 °C. Conversely, the DP synthesis of electrode particles has the advantage of producing pure, highly crystalline particles (due to synthesis at high temperatures) but the disadvantage of a high processing cost. WP and DP were used to manufacture pastes for low-temperature curing, and the physical properties of the pastes and the electrode characteristics after low-temperature curing were compared between powder types. Shear stress as a function of the shear rate shows that the WP paste is a plastic fluid, whereas the DP paste is a pseudoplastic fluid, closer to a Newtonian fluid. Screen printing the Ag pastes and curing for 30 min at 130 °C produces a nonconductive WP paste, whereas it produces a DP paste with a conductivity of 61 mΩ/sq, indicating that the highly crystalline DP paste is advantageous for low-temperature curing.
