Increased level of polymerase Ⅲ transcribed Alu RNA in hepatocellular carcinoma tissue

There have been extensive observations that RNA containing repetitive elements accumulates in transformed cells and tumor tissues. In the present study, we first obtained result consistent with previous observations by in situ hybridization.

Sleeve Gastrectomy and Gastric Banding: Effects on Plasma Ghrelin Levels

Background: Different changes of plasma ghrelin levels have been reported following gastric banding, Roux-en-Y gastric bypass, and biliopancreatic diversion. Methods: This prospective study compares plasma ghrelin levels and weight loss following laparoscopic sleeve gastrectomy (LSG) and laparoscopic adjustable gastric banding (LAGB) in 20 patients. Results: Patients who underwent LSG (n=10) showed a significant decrease of plasma ghrelin at day 1 compared to preoperative values (35.8 ± 12.3 fmol/ml vs 109.6 ± 32.6 fmol/ml, P=0.005). Plasma ghrelin remained low and stable at 1 and 6 months postoperatively. In contrast, no change of plasma ghrelin at day 1 (71.8 ± 35.3 fmol/ml vs 73.7 ± 24.8 fmol/ml, P=0.441) was found in patients after LAGB (n=10). Increased plasma ghrelin levels compared with the preoperative levels at 1 (101.9 ± 30.3 fmol/ml vs 73.7 ± 24.8 fmol/ml, P=0.028) and 6 months (104.9 ± 51.1 fmol/ml vs 73.7 ± 24.8 fmol/ml, P=0.012) after surgery were observed. Mean excess weight loss was higher in the LSG group at 1 (30 ± 13% vs 17 ± 7%, P=0.005) and 6 months (61 ± 16% vs 29 ± 11%, P=0.001) compared with the LAGB group. Conclusions: As a consequence of resection of the gastric fundus, the predominant area of human ghrelin production, ghrelin is significantly reduced after LSG but not after LAGB. This reduction remains stable at follow-up 6 months postoperatively, which may contribute to the superior weight loss when compared with LAGB.     

Raloxifene prevents the growth of uterine leiomyomas in premenopausal women

OBJECTIVE: To evaluate the effects of raloxifene administration on uterine leiomyoma size in premenopausal women. DESIGN: Prospective, randomized, open-label, controlled clinical trial. SETTING: Tertiary care unit, University of Vienna, Austria. PATIENT(S): Twenty-five premenopausal women with uterine leiomyomas. INTERVENTION(S): Three months of treatment with raloxifene (180 mg/d) or no treatment. MAIN OUTCOME MEASURE(S): Baseline to end point percent change difference in leiomyoma volume between the therapy and control groups. RESULT(S): Raloxifene treatment prevented the progression of uterine leiomyomas. Compared with no medical intervention, raloxifene resulted in a decrease of myoma volume. Raloxifene was clinically well tolerated. No significant differences were detected in symptoms related to leiomyomas and hormonal status. CONCLUSION(S): In premenopausal women, high-dose raloxifene is well tolerated and inhibits the growth of leiomyomas.     

Austrian infliximab experience in Crohn's disease: a nationwide cooperative study with long-term follow-up

OBJECTIVE: To determine the nationwide experience with infliximab for the treatment of Crohn's disease in Austria. DESIGN: National multicentre retrospective postal questionnaire survey. SETTING AND PARTICIPANTS: All institutions using infliximab for Crohn's disease in the years 1999 and 2000 were identified by the registry of the local provider of this drug. OUTCOME MEASURES: Response after first treatment course according to physician global assessment, number of subsequent infliximab infusions, disease activity at end of follow-up, avoidance of steroids, frequency of surgery for Crohn's disease, and adverse events. RESULTS: Questionnaires were returned by 32/35 (91%) centres approached. A total of 748 infusions were administered to 153 patients. After the first treatment course an excellent or good response occurred in 48/58 (83%) patients with luminal disease, and in 67/95 (71%) patients with fistulous disease (P < 0.05). After the first treatment course 108 (71%) patients received further infliximab therapy. At a mean follow-up of 29 months, 50% of patients had improved since baseline without requiring surgery for Crohn's disease. Steroid withdrawal was achieved in 25% of patients. Surgery had been performed in one-third of patients and was associated with lacking response to the first treatment course (P < 0.001) and with fistulous disease (P = 0.012). Co-medication with azathioprine favoured the initial response and steroid withdrawal (P < 0.05). One patient died from myocarditis; other adverse events were consistent with that seen in other studies of infliximab. CONCLUSIONS: The Austrian experience with infliximab for Crohn's disease is in general accordance with results from clinical trials and post-marketing studies from single centres. A substantial subgroup of patients appear to have a prolonged benefit from infliximab therapy.
