[Industrial vibrations and their repercussions on the basic functions of the genital system in women]. / Proizvodstveni vibratsii i otrazhenieto im vurkhu osnovnite funktsii na polovata sistema u zhenata

PIP: The increase in socialist industrialization has seen the great increase in levels of industrial noise, as well as the increase of female industrial workers. The biological effects of vibrations depend on the frequency, amplitude, and duration of the vibration. The most unfavorable are those with a frequency of 100-250 and an amplitude of .005 mm. General vibrations over a prolonged period of time lead to a typical syndrome of vegetative dysfunction and angiodystonic effects on a neurological basis. In the cardiovascular system, these effects are normally in the form of spastic reactions and perinephritis. The genital system function is particularly sensitive to vibrative disruptions, increasing with the frequency of the vibrations (such as with vehicle operators). Menstrual dysfunction is the most common of such disruptions. The cardiac, nervous, and muscular types of anomalies are well documented. What is now encouraged is research into prophylatic measures to prevent such disruptions.^ieng

[Use of a urinary balloon catheter in abortions after the 20th week of gestation and in premature labor]. / Izpolzuvane na uretralen balon katetur pri aborti sled 20-ata gestatsionna sedmitsa i pri prezhdevreminni razhdaniia.

PIP: The authors report on their experience with application of urethral balloon-catheter with a volume of 75-100 ml for pregnancy interruption due to obstetric indications after the 20th week of gestation. The study was carried out on 22 women and failure was recorded in only 1 case. All the pregnant women had a low pelvic score--from 0-4--but 11 had live fetuses. Oxytocin infusion (during placement of the balloon or during the course of delivery) was used in 19 women. The dilatation, obtained by the balloon-catheter, was from 4-6 cm and took about 4 hours on the average; duration of delivery was 10 hours on the average. No complications were recorded. The authors feel that the application of a urethral balloon-catheter replaces successfully the original obstetric-balloon catheter of Slavcev-Minceva after the 20th week of gestation, and its use in obstetric practice is recommended.
