The authors devised a new method for making a maxillary prosthesis with a hollow obturator, which was named the Balloon Technique. This new technique has a number of advantages over the conventional method in that it not only facilitates the molding of a soft plastic hollow obturator in a single process, but also simplifies the trial fitting of the completed obturator. Furthermore, it makes possible firm adhesion of the hollow obturator and the denture base by the hot-melt method while the denture base resin is cured. Finally, the completed maxillary prosthesis is extremely light. 相似文献
2 patients with leg ulcers got worse after the application of a compound mixture of sugar and povidone-iodine (sugar/PI compound). Because they had been suffering from stasis dermatitis, symptoms of contact dermatitis were ambiguous. Patch tests showed positive reactions to 10% povidone-iodine in water and 5% potassium iodide in water, with no response to sugar. They were also tested with sugar/PI compound, containing 3% povidone-iodine, resulting in another positive reaction. They improved after the application of sugar/PI compound was discontinued. Contact dermatitis from topical agents should be considered as more probable than angry back syndrome in cases of leg ulcer. 相似文献
We provided psychological preparation to children who were hospitalized for endoscopy. We performed a multifaceted evaluation of the effects of the preparation to identify appropriate methods for individual children. The subjects were 20 children, ages 4 to 15 years (average 9.9 years), who were divided into 3 groups according to the preparation methods. From our study, we suggest that it is important to discuss the preparation methods for medical procedures using methods appropriate to the level of cognitive development of each individual child. 相似文献
The purpose of this study was to analyze apoptosis in the vessel wall after stent implantation in the canine portal vein and
also to investigate the expression of the p21 cyclin-dependent kinase inhibitor, which may regulate cellular proliferation
after vascular injury. Uninjured, control veins had few detectable TUNEL-positive cells in the intima and media (0.829 ± 0.413%).
At 4 weeks after stent implantation, TUNEL-positive cells significantly increased to 50.5 ± 4.639%. These cells were predominantly
located around the stent struts, and appeared to be smooth muscle cells morphologically. At 12 weeks, 44.7 ± 6.178% of the
intimal and medial cells were still TUNEL positive, and there was no significant difference between 4 and 12 weeks. P21 was
not detected in uninjured, normal veins. At 4 and 12 weeks after stent implantation, positive p21 immunostaining was sparsely
expressed in the intima and media adjacent to the stent struts. Thus, stent implantation induced a prolonged apoptotic response
and increased expression of p21 in the portal venous system. This prolonged apoptotic response, possibly regulated by p21,
may have a significant role in modulating the cellularity of intimal formation. 相似文献
We have previously reported the effectiveness and safety of nivolumab in patients with head and neck cancer (HNC) in real-world clinical practice in Japan. Here, we report long-term outcomes from this study in the overall population and subgroups stratified by subsequent chemotherapy.
Methods
In this multicenter, retrospective observational study, Japanese patients with recurrent or metastatic (R/M) HNC receiving nivolumab were followed up for 2 years. Effectiveness endpoints included overall survival (OS), OS rate, progression-free survival (PFS), and PFS rate. Safety endpoints included the incidence of immune-related adverse events (irAEs).
Results
Overall, 256 patients received a median of 6.0 doses (range: 1–52) of nivolumab over a median duration of 72.5 days (range: 1–736). Median OS was 9.5 months [95% confidence interval (CI) 8.2–12.0] and median PFS was 2.1 months (95% CI 1.8–2.7). A significant difference between 2-year survivors (n = 62) and non-2-year survivors was observed by median age (P = 0.0227) and ECOG PS (P = 0.0001). Of 95 patients who received subsequent chemotherapy, 54.7% received paclitaxel ± cetuximab. The median OS and PFS from the start of paclitaxel ± cetuximab were 6.9 months (95% CI 5.9–11.9) and 3.5 months (95% CI 2.3–5.5), respectively. IrAEs were reported in 17.2% of patients. Endocrine (7.0%) and lung (4.3%) disorders were the most common irAEs; kidney disorder (n = 1) was newly identified in this follow-up analysis.
Conclusions
Results demonstrated the long-term effectiveness of nivolumab and potential effectiveness of subsequent chemotherapy in patients with R/M HNC in the real-world setting. Safety was consistent with that over the 1-year follow-up.
