Analysis of 100 cases of missing IUD strings.

In a study of 100 patients with missing IUD strings 69 women had their IUD in utero (4 were pregnant) and 17 had unnoticed expulsions (4 pregnancies); 9 devices were in the peritoneal cavity and one had perforated the cervix. Since the IUD was in the uterine cavity in the majority of these cases, most contraceptors whose IUD strings disappear can be managed in the office or clinic with relatively simple techniques to locate and remove the device.

Inhibition of the oxidative metabolism of human spermatozoa by a heat-labile factor in seminal plasma.

The effect of different media on the oxidative and glycolytic metabolism and on the motility of human spermatozoa has been investigated. Sperm resuspended in Ringer's solution produce more carbon dioxide than sperm in the original seminal plasma. In addition, sperm resuspended in heated seminal plasma have a higher carbon dioxide production and higher oxygen uptake than sperm in untreated seminal plasma. The mean lactic acid production was not significantly affected by different media. The motility of sperm in heated seminal plasma was poorer than that in untreated seminal plasma, although the percentage of cells that stained with eosin did not differ in the two media. After being heated, seminal plasma not only continued to take up oxygen but did so at a higher rate. The results of the present study suggest that seminal plasma contains a heat-labile component that inhibits the oxidative metabolism of human sperm but does not significantly alter sperm glycolysis.

Gonorrhea screening program in a women's hospital outpatient department: results and analysis of risk factors.

Endocervical cultures for Neisseria gonorrhoeae were taken from 4,285 new patients attending the emergency room and outpatient clinics at Women's Hospital, Los Angeles County-University of Southern California Medical Center. Of these, 144 (3.4%) were positive. Clinic-specific rates were: emergency room 9.0%, family planning clinic 2.3%, therapeutic abortion clinic 2.2%, and prenatal clinic 1.0%. An additional 70 return patients were cultured because of history, symptoms, or signs suggestive of gonorrhea; 14% of these "nonscreen" cultures were positive. Rates for the emergency room and nonscreen category were significantly greater than rates from the clinics. A questionnaire was used to determine patient characteristics in an attempt to identify a high-risk population. Variables of age, race, marital status, history of previous veneral disease or pelvic infection, number of sexual partners, and suspicion of venereal disease were significantly related to the incidence of positive cultures. Obstetrical history and symptoms of cramping or discharge were not related.

Accidental insertion of multiple IUDs.

Data are presented for 7 women, each having two IUDs in utero. Five of these patients developed symptoms of abnormal bleeding and/or pelvic pain and 2 were asymptomatic. Three women had received the second IUD because it was assumed the first one had been expelled when the filaments were no longer palpable or visible. Other causes, as well as the prevention, diagnosis, and potential danger of this complication, are discussed.
