Development and validation of prediction models for endometrial cancer in postmenopausal bleeding.

Objective: To develop and assess the accuracy of risk prediction models to diagnose endometrial cancer in women having postmenopausal bleeding (PMB).

Methods: A retrospective cohort study of 4383 women in a One-stop PMB clinic from a university teaching hospital in Hong Kong. Clinical risk factors, transvaginal ultrasonic measurement of endometrial thickness (ET) and endometrial histology were obtained from consecutive women between 2002 and 2013.

Transcervical intralesional vasopressin injection compared with placebo in hysteroscopic myomectomy: a randomized controlled trial.

Objective: To evaluate the efficacy of transcervical intralesional vasopressin injection to submucous myoma in hysteroscopic myomectomy from 2011 to 2014.

Methods: This was a prospective, randomized, double-blind study in a single center. Forty premenopausal women with symptomatic submucous myoma requiring hysteroscopic myomectomy were randomized to transcervical intralesional vasopressin injection or placebo in a 4:4 ratio.
