摘要:

Cesarean section (CS) has been an integral part of modern obstetrics during the last decades. As safety has increased, so too has the range of problems that CS is used to solve, to a degree that it must cause medical concern. There is a great danger in the blind faith that CS is the only way out in every difficult obstetric situation. The problem can always be easily solved by CS in an acute difficult obstetrical situation. However, CS is a major abdominal surgery and it may present any complication that besets major surgery including severe intraoperative and postoperative complications, a much greater risk for maternal death compared to vaginal delivery and also late complications, i.e. secondary involuntary infertility. Therefore, CS should never be undertaken lightly and without serious consideration of the justifications, preparations and all ancillary support.

摘要:

Lamellar body material was isolated by highspeed centrifugation from the amniotic fluids of 10 mildly diseased patients followed longitudinally and of 60 other women. Three stages of development were defined: (1) immature stage: the phospholipid concentration is less than 20 µmol/l and phosphatidylcholine (PC) is approximately 50%; (2) transitional stage: the phospholipid concentration is between 18 and 40 µmol/l, of which PC is approximately 75% and phosphatidylinositol (PI) 10%. Phosphatidylglycerol (PG) is absent or present at very low concentrations; (3) mature stage: the phospholipid concentration is above 40 µmol/l; its PC percentage is 75% or more. PG is present and the percentage of PI decreases. An increase in phospholipid concentration of 3.27 ± (SD) 0.75 µmol/l/day was found during the transitional stage. The rate of increase enables us therefore to approximate the number of days that it will take before the fetal lung is ma

摘要:

In 25 pregnant females with a placental weight below the 20th percentile uteroplacental blood flow measurements using 113mIn-transferrin were performed in the 3rd trimester of pregnancy. Twelve patients with pregnancy-induced hypertension (PIH) were compared to 13 females with normal blood pressures. The results of uteroplacental blood flow measurements showed normal flow patterns in only 6 of the 25 subjects and were significantly worse in the group with PIH. Babies of patients with PIH had a mean birth weight of 1,100 g at a mean gestational age of 34.2 weeks versus 1,752 g and 37.4 weeks for newborns without PIH. Perinatal mortality was significantly higher in the PIH group. In combination with a small placenta PIH compounds the fetal risk.

摘要:

The effect of electric stimulation of the uterine cervix on vasopressin and prolactin secretions was investigated in 16 patients with uterine myomas and/or hypermenorrhea. One month after hysterectomy a similar stimulation was induced near the fornix of the vagina. Particularly the first test also seemed to be a considerable psychic stress for the patients. The stimulation did not cause any significant changes in plasma vasopressin and prolactin concentrations.

摘要:

The prognostic value of the postcoital (PC) test was studied in two groups of women in whom the infertility workup differed only in the way the PC test was timed. Fifty patients were investigated in a traditional way. In this group the PC test failed to have any substantial prognostic value. In a second group consisting of 54 patients, the PC test was timed applying ultrasonographic criteria for ovarian follicular development. This resulted in a highly significant prognostic test. Timing of the PC test by ultrasound enhanced both the reliability and the efficacy of the standard fertility investigation.

摘要:

In cycling rats exposed to a controlled light schedule of 12 h of light daily from 22.00 to 10.00 h the concentration of estradiol in the anterior hypothalamus at 5.00–6.00 h on the day of proestrus was significantly higher than those at 0.00–1.00 h on day 1 of diestrus and estrus, and was about twofold higher than serum estradiol concentration, which reached a peak at 5.00–6.00 h on the same day. Autoradiographically, the uptake of tritiated estradiol by the nuclei of neurons in the nucleus (n.) preopticus, pars suprachiasmatica (POSC), n. preop-ticus periventricularis (POP), and anterior part of n. anterior hypothalami (AAH) was significantly higher at 1.00 h on the day of diestrus 1 than at 6.00 h on the day of proestrus and at 1.00 h on the day of estrus. These results suggest that the POSC, POP and AAH may be target sites in the anterior hypothalamus of estradiol for its feedback action.

摘要:

In 20 female rabbits the influence of absorbable and nonabsorbable suture material on microsurgical anastomosis of the oviduct was investigated. No significant superiority of polyglactin 910 over polypropylene could be demonstrated. Concerning histological reaction to the different suture materials as well as pregnancies (calculated by nidation indices) the results were comparable. The modern suture materials obviously do not influence the functional sequelae of microsurgical reanastomosis of the rabbit fallopian tube.

摘要:

A urethral valve has been constructed which can be mounted to an indwelling bladder catheter. Since the outflow resistance of the valve can be varied the intensity of the bladder training, i.e. the amount of work the detrusor has to produce to open it, can be varied simultaneously. Twenty-one valves were tested on 12 patients suffering from severe urgency or urge incontinence. All but two valves functioned properly from a technical point of view. From a clinical point of view bladder training with the valve was successful in 10 patients. It is concluded that the new technique might be considered a future alternative to presently existing methods for treatment of urgency or urge incontinence.

摘要:

We made a retrospective study of the flora found in the vaginal smears of sexually active women who presented with a mosaic colposcopic pattern of the uterine cervix in an attempt to study some of its epidemiologic factors. Of the 195 cervico vaginal cytologies of patients with mosaic, 61 revealed an abnormal flora (31.2%) while of the 9,856 patients without mosaic, only 2,234 cytologies had an abnormal flora (22.7%) demonstrating a statistically significant higher frequency (p < 0.0001) of an abnormal flora in women with a mosaic pattern on the cervix. A statistically significant association (p < 0.02) was encountered between the presence of Gardnerella vaginalis and the mosaic colposcopic pattern, and surprisingly a statistically greater frequency (p < 0.05) of biopsied dysplasias in the same group. At the moment we can interpret these observations as nothing more than interesting initial findings.
