Study Objective: To assess the safety and effectiveness of the NovaSure Impedance Controlled Endometrial Ablation System for the treatment of excessive uterine bleeding in premenopausal and postmenopausal women with intracavitary disease (polyps or myomas) up to 3 cm.
Design: Prospective, single-arm study. (Canadian Task Force Classification II-2.)
Setting: Academic medical center.
Patients: This clinical study was conducted in 65 women with menometrorrhagia with confirmed (type I and II) submucous myomas up to 3 cm with and without polyps.
Intervention: Patients were treated with the NovaSure System and received no hormonal or mechanical pretreatment to thin the endometrial lining or as a uterine pathologic condition shrinking agent.
Measurements And Main Results: All patients were diagnosed with intracavitary disease during office hysteroscopy. Patients completed menstrual questionnaires at the initial screening and at 1 year after treatment. Twelve-month results demonstrated that the NovaSure System was effective in reducing excessive uterine blood loss. Success (defined as reduction to normal bleeding) was observed in 95% (95% CI: 86%-99%) of patients, with 69% (95% CI: 56%-80%) reporting amenorrhea at 1 year after treatment. The median treatment time (time of energy delivery) was 78 seconds (range 61-120 seconds). All patients underwent the procedure under local or intravenous sedation. No intraoperative or postoperative adverse events were reported. There was a significant decrease in premenstrual symptoms and dysmenorrhea at 12 months after the procedure. Ninety-five percent (95% CI: 86%-99%) of patients were satisfied with the procedure.
Conclusion: Clinical results of this study demonstrate that the NovaSure System is safe and effective in treatment of patients with menometrorrhagia caused by intracavitary disease up to 3 cm.

Objectives: To assess the predictive value of magnetic resonance imaging for vesicovaginal fistula development in cervical cancer patients with bladder invasion treated with definitive chemoradiotherapy.
Methods: A retrospective review was conducted of the medical records of 43 cervical cancer patients with bladder invasion between 1999 and 2015. Bladder invasion was confirmed through magnetic resonance imaging (scores ≥3) or cystoscopic findings, with or without biopsy.

We present a case of a 72-year-old female patient with dyspnea and lipothymia. Echocardiography demonstrates an intracavitary cystic mass that fills almost all left atria causing supravalvular obstruction. The magnetic resonance image revealed a 53 × 47 × 48 mm heterogeneous mass with regular edges, tissue characterization suggested myxoma.

Abdominal aortic aneurysm is a potentially fatal vascular inflammatory disease characterized by infiltration of various inflammatory cells.The GABA-A receptor is expressed in many inflammatory cells such as macrophages and T cells and has anti-inflammatory and antioxidant effects. Therefore, the GABA-A receptor may become a potential therapeutic target for abdominal aortic aneurysms.
