The findings of first-trimester ultrasound scans are analyzed. The patients were divided into two groups according to the reliability of their alleged date of last menstrual period and the regularity of their menstrual cycle. The cost-effectiveness of a routine first trimester scan as compared to a selective approach is calculated. Based on these data we question the performance of a routine first-trimester scan.

Three commercially available RIA kits for serum and urinary LH were assessed for their usefulness to detect endogenous LH rise in patients receiving ovarian stimulation as part of an in vitro fertilization treatment for infertility. Prerequisites included a turn-around time of 5 hours for an assay of 100 tubes. The following parameters were evaluated: reproducibility of standard curve, sensibility, precision profile, within- and between -assay precision, analytical drift, recovery and linearity.

Sexually transmitted diseases (STDs) include diseases that are mainly transmitted through sexual intercourse, though some may also be transmitted vertically from mother to child. The research has been focussing on the role of maternal STDs (gonococcal and chlamydial infections, syphilis, group B streptococcal, Ureaplasma urealyticum, Mycoplasma hominis, Trochomonas vaginalis and bacterial vaginosis) on pregnancy outcome. Furthermore, studies on the epidemiology of Human Immuno-deficiency Virus (HIV) infection and the impact of maternal HIV infection on pregnancy outcome were conducted.

Aan de hand van twee gevallen wordt een beknopt overzicht gegeven van de endoscopische behandeling van een niet-geruptureerde tubaire zwangerschap. De aandacht wordt erop gevestigd dat de laparascopie niet enkel als investigatiemiddel, maar ook als therapeutische toegangsweg kan aangewend worden. Gesteund op eigen ervaring en op de literatuurgegevens wordt ingegaan op de belangrijkste technische data van de methode.

Sexually transmitted diseases (STDs) are major health problems in many parts of the world, especially in developing countries, as illustrated by high prevalence rates and a high rate of complications and sequelae. STDs are medically, socially and economically important, mainly because of their sequelae, which hit women and neonates in the first place. Ectopic pregnancy, spontaneous abortion and stillbirth, prematurity and low birth weight, congenital and perinatal infections, and puerperal maternal infections represent outcomes of pregnancy in which STDs play important aetiological roles.

The frequency of the luteinized unruptured follicle (LUF) was determined in a population of 220 regularly cycling women, infertile for at least two years. Laparoscopy was performed during the very first days of the luteal phase. In 26 women without other demonstrable cause of infertility, a diagnosis of LUF was made based on the absence of an ovulation stigma and the low concentrations of progesterone (P) and 17 beta-oestradiol (E2) in peritoneal fluid (PF). Twenty of these 26 women underwent a culdocentesis 72-96 hours after the serum LH-rise in a following cycle.
