This study suggests that abdominal adipose tissue accumulation is closely associated with cardiovascular risk factors in obese children, and among abdominal adipose tissue compartments, visceral fat thickness was strongly correlated with the elastic properties of the abdominal aorta.

BackgroundAlthough liver biopsy is an easy procedure for hospitalized patients and outpatients, some complications may occur.ObjectivesTo evaluate the efficiency, complications, safety and clinicopathological utility of ultrasonographic-guided percutaneous liver biopsy in diffuse liver disease.Patients and MethodsIn our retrospective study, we evaluated ultrasound-assisted needle biopsies that were performed in outpatients from October 2006 to July 2010. The liver biopsies were performed following one-night fasting using the tru-cut biopsy gun (18-20 gauge) after marking the best seen and hypovascular part of the liver, distant enough from the adjacent organs.ResultsA total of 1018 patients were referred to our radiology department. Most of the patients had hepatitis B (60.6%). The biopsy specimens were recorded and sent to our pathology department for histopathological examination.ConclusionAccording to the results of our series, percutaneous liver biopsy using the tru-cut biopsy gun guided by ultrasonography can be performed safely. We resolve that routine ultrasound of the puncture site is a quick, effective and safe procedure. The complication rate is very low. The US-assisted percutaneous liver biopsy should be used for all cases.

Background and Aims: Trans-arterial chemoembolization (TACE) has become a widely accepted treatment in unresectable hepatocellular carcinoma (HCC). We aimed at comparing the efficacy of Degradable Starch Microspheres (DSMs)-TACE with 50 ± 7 µm versus 300-500 μm Drug Eluting Beads (DEB)-TACE in terms of initial clinical and radiological treatment response parameters. Material and Methods:A total of 54 patients with unresectable HCC who underwent DEB-TACE (n = 25) or DSMs-TACE (n = 29) were included in this retrospective study. Baseline demographic and clinical characteristics, duration of follow-up, local recurrence and survival status, as well as treatment outcome including treatment response via modified Response Evaluation Criteria in Solid Tumors (mRECIST) criteria, viable and total tumor diameter and serum alpha-fetoprotein (AFP) levels were analyzed in both study groups.Results: No significant difference was noted between the two groups in terms of local recurrence (31.6 vs. 16.7%) or mortality (73.9 vs. 85.7%) rates after 36-month and 12-month follow-up, respectively. DSMs-TACE vs. DEB-TACE was associated with significantly higher complete response rate (27.6 vs. 0.0%, p = 0.011) and significant decrease in serum AFP levels (p = 0.013). Conclusion:Both DSMs-TACE with 50 ± 7 µm microspheres and 300-500 μm DEB-TACE are effective for local control of unresectable HCC. Our findings revealed superiority of DSMs-TACE over DEB-TACEnin terms of initial clinical and radiological tumor response; though no significant difference was noted between the two patient groups in terms of local recurrence or mortality during follow up.
