This case emphasizes the importance of identifying underlying issues during history taking and physical examination in adults without risk factors. The early diagnosis of osteonecrosis assists in preventing joint collapse and can delay the requirement of joint replacements. High levels of suspicion are necessary to instigate investigation in persistent cases without the presence of risk factors.Purpose This study quantified the impact of respiratory motion on liver stiffness measurements according to different shear wave elastography (SWE) techniques and region of interest (ROI) methods, using liver fibrosis phantoms. Methods Three operators measured stiffness values in four phantoms with different stiffness on a moving platform with two SWE techniques (point-SWE [pSWE] and 2-dimensional SWE [2D-SWE]), three types of motion (static mode and moving mode at low and high speeds), and four ROI methods in 2D-SWE (circle, point, box, and multiple). The circular ROI method was used to compare the two SWE techniques. The occurrence of technical failure and unreliable measurements, stiffness values, and measurement time were evaluated. Results Technical failure was observed only in moving mode for pSWE and 2D-SWE (n=1 for both). Unreliable measurements were also only observed in moving mode and were significantly less common in 2D-SWE (n=1) than in pSWE (n=12) (P less then 0.001). No statistically significant differences in the technical failure rate or stiffness values were noted between the static and moving modes for both SWE techniques. selleck inhibitor The technical failure and unreliable measurement rates were not significantly different among the ROI methods for 2D-SWE. Stiffness values did not differ significantly according to the ROI method used in any moving mode. However, the multiple ROI method had significantly shorter measurement times than the circular ROI method for all moving modes. Conclusion 2D-SWE may be preferable for evaluating liver fibrosis in patients with poor breath-hold. Furthermore, 2D-SWE with multiple ROIs enables rapid measurements, without affecting liver stiffness values.Background/aims Liver biopsy (LB) remains the gold standard for the evaluation of liver disease. However, over the past two decades, many noninvasive tests have been developed and utilized in clinical practice as alternatives to LB. The aim of this study was to evaluate the clinical use and safety of LB in the era of noninvasive assessment of liver fibrosis. Methods This retrospective study included 1,944 consecutive cases of LB performed between 2001 and 2018 in a tertiary hospital. All of the LBs were conducted under ultrasonography guidance with 18-gauge cutting needles. Results LBs were performed an average of approximately 108 times per year during the study period. Chronic hepatitis B (25.3%) and suspected malignancy (20.5%) were the two most common indications for LB. The use of LB for nonalcoholic fatty liver disease increased from 8.1% to 17.2% in the past 5 years compared to the last 10 years, while that for viral hepatitis decreased from 40.3% to 18.9%. Discordance rate between the suspected diagnosis and the final diagnosis was 2.6% (51 cases). The overall rate of major adverse events was 0.05% (one case), which involved delayed bleeding at the biopsy site. Liver cirrhosis was observed in 563 cases (28.9%), and the presence of cirrhosis did not affect the frequency of complications (P=0.289). Conclusions LB is widely used in clinical practice as an irreplaceable diagnostic tool, even in the era of noninvasiveness. Ultrasonography-guided LB can be performed safely in patients with liver cirrhosis.Background/aims Exclusive enteral nutrition (EEN), an established modality for pediatric Crohn's disease (CD) is seldomly utilized in adults. The present study reports the outcome of EEN in adult CD patients at a tertiary care hospital in India. Methods This was a retrospective analysis of CD patients who received EEN as a sole modality/adjunct to other treatment. The primary and secondary outcomes changed in Crohn's Disease Activity Index (CDAI), and clinical response (decline in CDAI > 70), respectively, at 4 and 8 weeks. Subgroup analysis evaluated response across different phenotypes, EEN formulations and prior treatment. Linear mixed effect model was created to assess the predictors of EEN response. Results Thirty-one CD patients received EEN over median duration of 4 weeks (range, 2-6 weeks). CDAI showed a significant improvement post EEN at 4 (baseline 290 [260-320] vs. 240 [180-280], P= 0.001) and 8 weeks (baseline 290 [260-320] vs. 186 [160-240], P= 0.001), respectively. The cumulative clinical response rates at 4 and 8 weeks were 37.3% and 80.4% respectively. The clinical response rates at 8 weeks across B1 (n = 4), B2 (n = 18) and B3 (n = 9) phenotypes were 50%, 78.8% and 100% respectively (log-rank test, P= 0.093). The response rates at 8 weeks with polymeric (n = 8) and semi-elemental diet (n = 23) were 75% and 82.6%% respectively (log-rank test, P= 0.49). Baseline CDAI (odds ratio, 1.008; 95% confidence interval, 1.002-1.017; P= 0.046) predicted response to EEN. Conclusions EEN was effective in inducing clinical response across different phenotypes of CD. Baseline disease activity remained the most important predictor of clinical response to EEN.The first edition of the guidelines for the use of ultrasound contrast agents was published in 2004, dealing with liver applications. The second edition of the guidelines in 2008 reflected changes in the available contrast agents and updated the guidelines for the liver, as well as implementing some nonliver applications. The third edition of the contrast-enhanced ultrasound (CEUS) guidelines was the joint World Federation for Ultrasound in Medicine and Biology-European Federation of Societies for Ultrasound in Medicine and Biology (WFUMB-EFSUMB) venture in conjunction with other regional US societies such as Asian Federation of Societies for Ultrasound in Medicine and Biology, resulting in a simultaneous duplicate on liver CEUS in the official journals of both WFUMB and EFSUMB in 2013. However, no guidelines were described mainly for Sonazoid due to limited clinical experience only in Japan and Korea. The new proposed consensus statements and recommendations provide general advice on the use of Sonazoid and are intended to create standard protocols for the use and administration of Sonazoid in hepatic and pancreatobiliary applications in Asian patients and to improve patient management.
