Prevalence of high-risk HPV and cervical dysplasia in IUD users and controls: a cross sectional study.

Objective: To examine the prevalence of infections with high-risk human papillomavirus (HPV) and cervical dysplasia, and the clearance rate of HPV infections, in users of different kinds of intrauterine devices (IUDs) and other contraceptive methods.

Methods: A cross-sectional register-based study including 16,181 women aged 30-49 years participating in the screening programme for cervical cancer in a Swedish County in 2017-2018. Data on contraception from screening records was paired with the HPV test results, cytological and histological follow-up tests and subsequent HPV test.

Millimeter wave silicon micromachined waveguide probe as an aid for skin diagnosis--results of measurements on phantom material with varied water content.

Background: More than 2 million cases of skin cancer are diagnosed annually in the United States, which makes it the most common form of cancer in that country. Early detection of cancer usually results in less extensive treatment and better outcome for the patient. Millimeter wave silicon micromachined waveguide probe is foreseen as an aid for skin diagnosis, which is currently based on visual inspection followed by biopsy, in cases where the macroscopical picture raises suspicion of malignancy.

Initial experiences with a miniaturized pressure transducer during coronary angioplasty.

A newly constructed pressure sensor with a diameter of 0.45 mm was evaluated in 15 patients undergoing balloon coronary angioplasty (PTCA). The sensor and an optic fiber were mounted on a 0.
