Pressure-velocity analysis of uterine muscle during spontaneous dysmenorrheic contractions in vivo

Article Abstract:

Painful menstrual periods, dysmenorrhea, may be caused by muscles of the uterus contracting. Intrauterine pressure and the rate of change of pressure were measured to reveal the relationship between uterine contractions and dysmenorrhea. Contractions were measured under a variety of conditions Topograms, a type of graph measuring various pressure elevations, with and without the administration of pain medication, show that uterine muscles are able to make fast pressure changes even though uterine pressure is quite high. Pressure-slope topograms may be a useful tool in measuring pressure inside the uterus and how it affects menstrual pain.

Potential for an external vaginal antiitch cream containing benzocaine to cause methemoglobinemia in healthy women

Article Abstract:

Vaginal anti-itch creams containing benzocaine may be safe when used as directed and may not create a lack of oxygen in the blood. Researchers analyzed 55 women for the ability of blood to transport oxygen before and after seven days of using an external vaginal anti-itch cream containing 20% benzocaine. Use of the benzocaine cream did not compromise blood oxygen transport. Infants and elderly women may be more susceptible to the oxidizing action of benzocaine, so use of the cream in these populations should be cautioned. The cream should not be used beyond seven days.

Use of a subcutaneous closed drainage system and antibiotics in obese gynecologic patients

Article Abstract:

There may be fewer complications following gynecological surgery in obese patients if surgeons place drains below the skin and treat the patient with preventive antibiotics. One hundred ninety-seven obese patients undergoing gynecological surgery either did or did not have a drain placed below the incision and did or did not take preventive antibiotics following surgery. Patients with no drain and who took no antibiotics had the most complications (14%) while those with both a drain and who took antibiotics had the fewest complications (2%).
