“…[4][5][6][7][8] This study demonstrated that similar symptoms were observed in PCS, 3,4) and similar leukocytosis was also observed in PCS 10) ( Table 4). Recent studies have suggested that the etiology of PES is related to an inflammatory process/cascade and tissue ischemia and necrosis although there are some differences in blood flow preservation between PCS and PES.…”

“…11,12) Importantly, almost all such studies reported a short-lived and reversible influence on the immune reaction that mostly returned to preoperative values within 24 h. Given this, in our study, we applied the PCS diagnostic criteria based on the scoring of such symptoms between 24 h and 48 h after the operation. 7) We also suspected that some symptoms were caused by nephropathy induced by the contrast medium and radiation sickness. However, there was no significant difference in operative time and contrast medium volume between the PCS group and the non-PCS group.…”

“…It has been speculated that these symptoms may be the result of an inflammatory response. [4][5][6][7][8] We define these symptoms as post-aneurysmal coiling syndrome (PCS). The purpose of this study is firstly to analyze the clinical risk factors of PCS, and secondly to prevent patients from experiencing PCS.…”

Objective: Unidentified fever, headache, and gastrointestinal symptoms after endosaccular coil embolization are occasionally observed in patients with unruptured cerebral aneurysms. We defined these symptoms as post coiling syndrome (PCS) and analyzed the clinical risk factors involved. Methods:We applied the PCS diagnostic criteria based on the scoring of symptoms, which include fever, headache, nausea, and/or vomiting. Thirty-six consecutive patients were included in this retrospective study. Systematic follow-up included clinical and blood examinations.Results: Based on our criteria, 11 of 36 patients were diagnosed with PCS. Between patients in the PCS group and patients in the non-PCS group, we recognized significant differences in age (63.4 ± 12.5 vs. 53.8 ± 12.9, respectively; p <0.029) as patient background and in aneurysmal diameter (9.96 ± 4.24 vs. 6.48 ± 3.06, respectively; p <0.049), aneurysmal volume (242 ± 254 vs. 87.9 ± 70.1, respectively; p <0.015), total coil length (122 ± 106 vs. 39.1 ± 25.7, respectively; p <0.0021), and volume embolization ratio as aneurysmal data (41.9 ± 8.1 vs. 30.7 ± 8.5, respectively; p <0.0019). In addition, we recognized a significant difference in postoperative leukocytosis as an inflammatory factor. Conclusions:Patient age, aneurysmal diameter, aneurysmal volume, total coil length, and volume embolization may enable the prediction of PCS.

AbstractA precise knowledge of antineoplastic drugs is an indispensable basis for the care of patients with cancer. The mechanisms of action and resistance, cross-resistance patterns, pharmacodynamics and pharmacokinetics, pharmacological interaction, and last but not least potential adverse effects should be part of this knowledge. As contemporary cancer care requires interdisciplinary and multiprofessional structures, the radiologist is an important a...

Objectives: To investigate whether radiofrequency (RF) ablation with low power (LP) or maximal power (MP) for hepatocellular carcinoma (HCC) can achieve optimal ablation and fewer adverse effects. Methods: RF ablation was performed with MP in 101 patients (129 tumours) and with LP in 46 patients (61 tumours). MP RF ablation used power of .120 W. RF power below this was designated as LP. Clinical outcomes were also analysed in subgroups of highrisk tumours near the bile duct and blood vessels. Results: Primary effectiveness was achieved in 91.8% in the LP group and 89.9% in the MP group (p50.795). 1 and 2-year local tumour progression rates were 28% and 30%, respectively, in the LP group, and 24% and 29%, respectively, in the MP group (p50.70). 1 and 2-year survival rates were 98% and 98%, respectively, in the LP group, and 93% and 90%, respectively, in the MP group (p50.216). The MP group had more adverse effects, with post-RF ablation syndrome, asymptomatic pleural effusion and ascites, than the LP group (20% vs 39% in the MP group; p50.027); however, there was no significant difference in major complication rates (6% in the MP and LP groups; p50.497). Among the patients with high-risk tumours, RF ablation using MP vs LP was comparable in primary effectiveness (91.7% vs 95.2%; p50.618), local tumour progression (42.9% vs 29.2%; p50.304) and overall complications (5% vs 8%; p50.618). Conclusion: RF ablation with LP and MP are comparable in clinical outcomes but considerably fewer adverse effects were encountered in the LP group.
