STUDY OBJECTIVE To analyze the clinical success of radiofrequency volumetric thermal ablation (RFVTA) at 3-year follow-up in terms of subject responses to validated questionnaires and surgical repeat intervention to treat myomas. DESIGN Prospective follow-up of patients for 36 months after treatment in a multicenter international trial of outpatient, laparoscopic ultrasound-guided RFVTA of symptomatic uterine myomas (Canadian Task Force classification II-1). SETTING University hospitals and private surgical centers. PATIENTS One hundred thirty-five premenopausal women (mean [SD] age, 42.5 [4.6] years; body mass index, 30.5 [6.1]) with symptomatic uterine myomas and objectively confirmed heavy menstrual bleeding (≥ 160 to ≤ 500 mL). INTERVENTIONS Laparoscopic ultrasound-guided RFVTA. MEASUREMENTS AND MAIN RESULTS One hundred four participants were followed prospectively for 36 months after treatment of myomas via RFVTA. For 104 evaluable participants with 36-month data, change in mean (SD) symptom severity from baseline (60.2 [18.8]) to 36 months was -32.6 (95% confidence interval, -37.5 to -27.8; p < .001). Health-related quality of life also was improved, from the baseline value of 39.2 (19.2) to 38.6 (95% confidence interval, 33.3 to 43.9; p < .001) at 36 months. Patient-reported Uterine Fibroid Symptom and Health-Related Quality of Life questionnaire subscores demonstrated statistically significant improvement from baseline to 36 months in all categories (Concern, Activities, Energy/Mood, Control, Self-consciousness, and Sexual Function) (p < .001). For the 104 participants with 36-month data, mean state of health scores (EuroQOL-5D Health State Index) improved from a baseline value of 71.0 (19.3) to 86.2 (11.7) at 36 months. The cumulative repeat intervention rate of 11% (14 of 135 participants) at 36 months was well below the possible 25% maximum expected at the beginning of the trial. CONCLUSION RFVTA of uterine myomas resulted in sustained relief from myoma symptoms and continued improvement in health-related quality of life through 36 months after ablation. The low repeat intervention data through 36 months is a positive outcome for patient well-being.

The effects of hormonal contraceptive use among women with viral hepatitis or cirrhosis of the liver: a systematic review

Nathalie Kapp; Ian Tilley; Kathryn M. Curtis

BACKGROUND This report evaluates the effects of hormonal contraceptive use among women with viral hepatitis or cirrhosis of the liver. METHODS PubMed and Cochrane databases were searched from inception to June 2008 for publications that examined the use of hormonal contraceptives among women with viral hepatitis or cirrhosis of the liver. RESULTS Six studies met the inclusion criteria. In one study of acute hepatitis, combined oral contraceptive (COC) use did not affect duration of hospitalization or successful disease resolution. The remainder of the studies examined chronic hepatitis or its sequelae. Women recovered from hepatitis experienced transaminase elevation with COC use which resolved after 4 weeks in one study or increased slightly over 6 months in another study. Hepatitis B virus carriers using COCs had similar transaminase levels as nonusing carriers over 6 months. Studies of chronic hepatitis C infection demonstrated no influence of COC use on progression or severity of liver fibrosis or development of hepatocellular carcinoma. CONCLUSION Data from one study suggest that COCs do not affect the course of acute hepatitis. Limited data from studies on chronic hepatitis or its sequelae suggest that COC use does not affect the rate of progression or severity of cirrhotic fibrosis, the risk of hepatocellular carcinoma in women with chronic hepatitis, or the risk of liver dysfunction in hepatitis B virus carriers.

BackgroundAlthough most myomas are asymptomatic, quality of life is compromised for many women with uterine fibroid disease. Twelve-month outcomes from the Halt Trial have been reported in the literature. Here we analyze the clinical success of radiofrequency volumetric thermal ablation (RFVTA) of symptomatic uterine fibroids at two years of follow up.MethodsProspective, multicenter, outpatient interventional clinical trial of fibroid treatment by RFVTA in 124 premenopausal women (mean age, 42.4 ± 4.4 years) with symptomatic uterine fibroids and objectively confirmed heavy menstrual bleeding (≥160 to ≤500 mL).Outcome measures included: subject responses to validated questionnaires, treatment-emergent adverse events, and surgical re-intervention for fibroids at 24 months postprocedure. Continuous and categorical variables were summarized using descriptive statistics and means and percentages. Comparisons between visits were based on t-tests using repeated measures models. P-values < 0.05, adjusted for multiplicity, were statistically significant.ResultsOne hundred twelve subjects were followed through 24 months. Change in symptom severity from baseline was –35.7 (95% CI, –40.1 to –31.4; p<.001). Change in health-related quality of life (HRQL) was 40.9 (95% CI, 36.2 to 45.6; p < .001). HRQL subscores also improved significantly from baseline to 24 months in all categories (concern, activities, energy/mood, control, self-consciousness, and sexual function) [p<.001]. Six patients underwent surgical re-intervention for fibroid-related bleeding between 12 and 24 months providing a re-intervention rate of 4.8% (6/124).ConclusionRadiofrequency volumetric thermal ablation of myomas significantly reduces symptom severity and improves quality of life with low surgical re-intervention through 24 months of follow up.Trial registrationClinicalTrials.gov: NCT00874029

BACKGROUND The effects of subcutaneous depo-medroxyprogesterone acetate (DMPA-SC) injection on androgenic markers in obese women have not previously been studied. STUDY DESIGN Five normal-weight [body mass index (BMI)=18.5-24.9 kg/m²], five obese (BMI=30-39.9 kg/m²) and five extremely obese (BMI≥40 kg/m²) women were recruited for this prospective experimental study in which 104 mg DMPA-SC was administered at baseline and 12 weeks later. Serum levels of total testosterone (T), androstenedione (A), dehydroepiandrosterone sulfate (DHEAS), 3α-androstanediol glucuronide and sex hormone-binding globulin (SHBG) were quantified by immunoassay methods at baseline and at 13 and 26 weeks following the first injection; free T was calculated. RESULTS At baseline, obese women had lower levels of A and SHBG and higher total and free T levels than normal-weight women. There were a statistically significant decrease in the levels from baseline to week 26 among all three BMI classes for A, total T and SHBG (p≤.03) and an increase from baseline to week 26 in weight (p=.02). In addition, there was a statistically significant decrease in DHEAS from baseline to week 13 among all three BMI classes (p=.01), which was not sustained at week 26 (p>.1). Overall, the three groups responded similarly to all changes at week 13, and there were no statistically significant differences between groups at any time point (p≥.06). CONCLUSION DMPA-SC use in normal-weight, obese and extremely obese women can decrease serum androgen markers.
