Effect of Er,Cr:YSGG laser with a side-firing tip on decontamination of titanium disc surface: an in vitro and in vivo study.

Purpose: To evaluate the effectiveness of an erbium, chromium:yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser with side-firing tip in decontamination of titanium (Ti) disc.

Methods: In the first test series, 29 Ti-discs were contaminated with Staphylococcus aureus and treated as follows: positive control (no treatment); Perioflow; Laser A (0.75 W, 100 Hz), Laser B (1.

Pelvic inflammatory disease: clinical overview.

Acute pelvic inflammatory disease (PID) adversely affects the health of 1 million American women annually. The best understood etiologic organisms are Chlamydia trachomatis and Neisseria gonorrhea; however, information regarding the contributions of facultative and causative anaerobes continues to emerge. Chronic PID presents a diagnostic and management challenge to health care providers.

A noninvasive method for recording the electrical activity of the human uterus in vivo.

Development of an electrohysterograph (EHG) for recording the electrical activity of the uterus in vivo has been blocked for 60 years by problems with artifacts and extraneous/reactive electrical activity. This study reevaluates a method of cervical recording that does not appear to have these limitations. A set of cervical electrode cups was used to record uterine activity of 33 normal subjects and patients who had dysmenorrhea, endometriosis, or chronic pelvic pain.
