Does Intermittent Pringle Maneuver Increase Postoperative Complications After Hepatectomy for Hepatocellular Carcinoma? A Randomized Controlled Trial.

Background: In a previous study, we have shown that intermittent Pringle maneuver (IPM) might increase postoperative complications after hepatectomy for various indications. Complications which thought to be related to IPM were ascites, pleural effusion, wound infection and intra-abdominal collection. The aim of this study was to test the hypothesis that applying IPM during hepatectomy for hepatocellular carcinoma (HCC) could increase postoperative complications.

Assessment of biopsy-proven liver fibrosis by two-dimensional shear wave elastography: An individual patient data-based meta-analysis.

Unlabelled: Two-dimensional shear wave elastography (2D-SWE) has proven to be efficient for the evaluation of liver fibrosis in small to moderate-sized clinical trials. We aimed at running a larger-scale meta-analysis of individual data. Centers which have worked with Aixplorer ultrasound equipment were contacted to share their data.

Tendon vascularity in overhead athletes with subacromial pain syndrome and its correlation with the resting subacromial space.

Background: Supraspinatus tendinopathy is one of the common causes of subacromial pain syndrome (SAPS) in overhead athletes. Changes in tendon vascularity have been reported in painful tendons; however, the prevalence and distribution have not been investigated in young overhead athletes.

Methods: We conducted a cross-sectional study of 47 overhead athletes (male, 31; female, 16) aged 18 to 36 years with SAPS for >3 months.

Safety and efficacy of sonographically guided high-intensity focused ultrasound for symptomatic uterine fibroids: preliminary study of a modified protocol.

Objectives: We aimed to assess the safety and efficacy of sonographically guided high-intensity focused ultrasound for treating patients with symptomatic uterine fibroids using a modified protocol.

Methods: This work was part of an ongoing prospective phase 1 study. Twenty patients with 22 symptomatic fibroids were treated with sonographically guided high-intensity focused ultrasound under no anesthesia.

Elastic modulus of muscle and tendon with shear wave ultrasound elastography: variations with different technical settings.

Standardization on Shear wave ultrasound elastography (SWUE) technical settings will not only ensure that the results are accurate, but also detect any differences over time that may be attributed to true physiological changes. The present study evaluated the variations of elastic modulus of muscle and tendon using SWUE when different technical aspects were altered. The results of this study indicated that variations of elastic modulus of muscle and tendon were found when different transducer's pressure and region of interest (ROI)'s size were applied.

Effects of vitamins C and E on oxidative stress markers and endothelial function in patients with systemic lupus erythematosus: a double blind, placebo controlled pilot study.

Objective: Patients with systemic lupus erythematosus (SLE) experience excess morbidity and mortality due to coronary artery disease (CAD) that cannot be fully explained by the classical CAD risk factors. Among emerging CAD risk factors, oxidative stress is currently being emphasized. We evaluated the effects of longterm antioxidant vitamins on markers of oxidative stress and antioxidant defense and endothelial function in 39 patients with SLE.

Ureteric jet in the anaesthetised child.

We have already suggested that there is an active bimodal sphincteric mechanism in the human vesicoureteral junction (VUJ). This mechanism is affected by immaturity, hormonal effects and surgical ablation. This study set out to investigate the effects of anaesthesia on this mechanism.

Ureteric jet in renal transplantation patient.

We have made a case for an active sphincteric mechanism at the VUJ modifying the ureteric jet Doppler waveform. The transplanted ureter does not have a normal VUJ, but retains inherent peristalsis. This study was to document any difference in the transplanted ureteric jet Doppler pattern.

Doppler waveform of the ureteric jet in pregnancy.

We have shown that the function of the bladder vesicoureteric junction (VUJ) can be studied by the Doppler waveform of the ureteric jet, and this reflects the active sphincteric mechanism of the VUJ. We wished to investigate if the hormonal changes of pregnancy cause any alteration of VUJ function. A total of 107 pregnant women and 375 nonpregnant women were recruited.

Immature ureteric jet doppler patterns and urinary tract infection and vesicoureteric reflux in children.

The Doppler waveform of the ureteric jet is the result of modification of ureteric peristalsis by an active sphincteric mechanism of the vesicoureteric junction (VUJ). The monophasic pattern is associated with immaturity. This study set out to see the correlation between this immature pattern with urinary tract infection (UTI) and vesicoureteric reflux (VUR) in children.

The ureteric jet doppler waveform as an indicator of vesicoureteric sphincter function in adults and children. An observational study.

The nature of the action of the vesicoureteric junction (VUJ) in humans is still controversial. We were interested in the reasons why the jet consists of several peaks. We hypothesised that the modification of the jet into a variable number of peaks is the result of an active sphincter mechanism at the VUJ.
