RESUMO
In many patients with pancreatic cancer the definite pathological diagnosis is limited due to the lack of safe needle entry routes, the high risk of conventional ultrasound-guided puncture and the low positive rate of single needle. To solve the situations in which there are no safe path for pancreatic biopsy, we used water isolation technology combined with contrast-enhanced ultrasound to perform puncture biopsy in 3 patients with pancreatic mass occupying under the guidance of coaxial needle in this study and remarkable results were achieved. The water isolation technique was used to avoid the damage to theimportant organs in front of the occupying area.

BACKGROUND: Bone cancer pain presents a clinical challenge with limitations of current treatments. Many patients seek additional therapies that may relieve pain. Many external applications of traditional Chinese medicines (EAs-TCMs) have been evaluated in clinical trials, but fewer are known about them outside of China. The objective of this study is to assess the efficacy for bone cancer pain. METHODS: A systematic literature search was conducted in seven databases until December 2014 to identify randomized controlled trials (RCTs) about EAs-TCMs in the treatment of bone cancer pain. The primary outcome was total pain relief rate. The secondary outcomes were adverse events at the end of treatment course. The methodological quality of RCTs was assessed independently using six-item criteria according to the Cochrane Collaboration. All data were analyzed using Review Manager 5.2.0. We included any RCTs evaluating an EA-TCM for the treatment of bone cancer pain. We conducted a meta-analysis. RESULTS: We included six RCTs with 534 patients. In general, the reporting of methodological issues was poor. Compared with morphine sulfate sustained release tablets (MSSRTs) or radiotherapy or bisphosphonates, we analyzed data from five trials reporting on complete response effect score (relative risk (RR) = 5.38, 95% confidence interval (CI) = 2.80-10.31, P < 0.00001) and partial response (RR = 1.18, 95% CI = 1.02-1.37, P = 0.02) and six trials reporting on total pain relief rate (RR = 1.49, 95% CI = 1.43-1.67, P < 0.00001). Six RCTs showed significant effects of EA-TCM for improving pain relief in patients with bone cancer pain. In addition, no severe adverse events were found. CONCLUSION: This systematic review showed positive but weak evidence of EA-TCM for bone cancer pain because of the poor methodological quality and the small quantity of the included trials. Future rigorously designed RCTs are required.

PURPOSE: To evaluate the diagnostic value of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) for hepatocellular carcinoma (HCC). MATERIALS AND METHODS: A systematic, comprehensive literature search was conducted in PubMed (2004 [Gd-EOB-DTPA was first approved in Europe in 2004] to April 2013), Embase (2004 to April 2013), Web of Science (2004 to April 2013), and the Cochrane Library (2004 to April 2013). The Quality Assessment of Diagnostic Studies (QUADAS) items was used to evaluate the quality of the included studies. Stata 12.0 was used to analyze the data. Pooled sensitivity (SEN), pooled specificity (SPE), pooled positive likelihood ratio (PLR), pooled negative likelihood ratio (NLR), pooled diagnostic odds ratio (dOR), and summary receiver operating characteristic (SROC) curves were calculated to assess the diagnostic value of the individual diagnostic tests. RESULTS: A total of 11 articles were included, involving 1578 nodules from four countries. The results of the meta-analysis showed that the pooled SEN, SPE, and SROC curve values were 0.92 (95% confidence interval [CI]: 0.89-0.94) 0.95 (95% CI: 0.93-0.97), and 0.98 (95% CI: 0.95-0.99), respectively, and subgroup analyses were performed. CONCLUSION: Gd-EOB-DTPA-enhanced MRI has value for the detection of HCC; in particular, it has high sensitivity for the detection of lesions larger than 10 mm.
