Background: Persistent infection with high-risk human papillomavirus (HPV) is a significant risk factor for cervical cancer. HPV typing and cytology are conducted in women of appropriate age to assess the risk of cervical lesions and to guide the need for further diagnostic procedures such as colposcopy, cervical biopsy, or treatment. This article explores methods to predict the risks of high-grade precancerous cervical lesions based on high-risk HPV typing.

Introduction: IUDs are effective, reversible and safe methods of contraception. The mechanism of action of IUDs as a group is inducing endometrial atrophy, apoptosis, altering tubal motility; preventing sperm permeability, fertilization, and implantation. Complications of IUD include menstrual disturbance, pelvic pain, and increased risk of ectopic pregnancy with contraceptive failure, device expulsion, uterine perforation or transmural migration with misplacement of the device.

The intrauterine device (IUD) is an important and highly effective means of contraception. Migration of the IUD, post implantation, out of the uterus is an infrequent complication, and its subsequent migration into the urinary bladder with formation of secondary bladder calculi, is even more infrequently reported. The authors report a 51 year old woman who had had her last child delivered via cesarean section 16 years ago.

Background: Intrauterine devices (IUDs) are among the most popular contraceptive methods globally due to their convenience and cost-effectiveness. However, improper placement can lead to complications such as device migration and uterine perforation, with increased risk observed when IUDs are implanted within four to six weeks postpartum. Typically, patients are asymptomatic or experience mild lower abdominal discomfort or minor abnormal vaginal bleeding following IUD displacement.

Background: A concern in high-income countries is that switching to 1-dose human papillomavirus (HPV) vaccination could cause a rebound in HPV infection and cervical cancer if 1-dose efficacy or duration were inferior to 2 doses. Using mathematical modeling and up-to-date trial-based data, we projected the population-level effectiveness of switching from 2-dose to 1-dose vaccination under different vaccine efficacy and duration assumptions in high-income countries.
Methods: We used HPV-ADVISE (Agent-based Dynamic model for VaccInation and Screening Evaluation), a transmission-dynamic model of HPV infection and cervical cancer, varying key model assumptions to identify those with the greatest impact on projections of HPV-16 and cervical cancer incidence over time: 1) 1-dose vaccine efficacy and vaccine duration, 2) mechanisms of vaccine efficacy and duration over time, 3) midadult (>30 years of age) sexual behavior, 4) progression to cervical cancer among midadults, and 5) vaccination coverage and programs.
