Prognostic value of ultrasound, HCG and progesterone in threatened abortion.

The diagnostic and prognostic value of ultrasound, beta-HCG subunit, and progesterone are evaluated in a prospective study in 169 patients with threatened abortion. Ultrasound diagnosis had just been introduced at the hospital when the study began and clinicians accepted the patients for treatment without receiving the ultrasound, HCG, or progesterone results. With ultrasound, a correct diagnosis of the in utero situation (true positive and true negative) was made at admission in 93% and after 1 week in 99% of the cases; in 1% of the cases intact pregnancies were mistaken for abortions (false positive). For the tests applied, ultrasound had the highest sensitivity in detecting a pathologic pregnancy and also the best predictive value when a pathologic condition was discovered.

Anal electrostimulation in urinary incontinence. Technical description of a new device.

A new electrical anal stimulator has been developed to treat urinary incontinence. The device is automatic and fully integrated with both battery and electronics in the plug. Shape, plastic material, electrodes, electrical parameters and electronic circuits have been carefully selected for optimal acceptability and therapeutic effect. A pilot study was performed in 24 women with stress, motor urge and mixed stress and motor urge incontinence where traditional incontinence therapy had failed. When the stimulator had been used for an average of 3.5 months, 25% were continent, 54% much improved and 21% without any effect of the treatment. Improved incontinence status was verified by positive changes in the urodynamic parameters in some of the patients after the treatment. No serious side effects have been observed. The present device is simple to handle for the patient and has satisfactory technical and mechanical properties. The preliminary clinical results are promising.

Randomised controlled trial of ultrasonographic screening in pregnancy.

510 of 1009 pregnant women in the Trondheim area (Norway) were randomly selected for ultrasound examination at the 19th and 32nd weeks of pregnancy in addition to routine antenatal care. Among the screened women, twins were diagnosed earlier and there were slightly fewer post-term inductions (2.8% versus 4.0%) and fewer low-weight births (2.2% versus 3.6% less than 2500 g), but none of these differences was statistically significant. There were no differences in the condition of the newborn. Small-for-gestational-age births were more often diagnosed antenatally in the screened group and the mothers received more active treatment. During pregnancy, screened women were admitted to hospital more often than unscreened women (15.5% versus 9.2%). The study revealed no adverse short-term biological effects from ultrasound. The cost of the screening programme, including associated costs such as extra hospital admissions, was about US$ 250 per pregnancy.
