Decrease in uterine rupture in Conakry, Guinea by improvements in transfer management.

Lack of an effective transfer system remains a major risk factor for uterine rupture, especially in developing countries. The implementation of a program of consultation, feedback and integration between peripheral delivery units and two hospitals resulted in a decrease in the incidence of uterine rupture from 0.20% to 0.12% and of maternal mortality after uterine rupture from 28% to 21%, respectively, after 6 months.

Uterine rupture--an analysis of 81 cases in Conakry/Guinea.

Eighty-one cases of uterine rupture in Conakry/Guinea are analyzed. With an incidence of 0.84%, i.e. 1 per 119 deliveries, uterine rupture is still a common problem in this region. In this analysis fetal mortality was found to be 75.3% and maternal mortality 20.9%. Mortality rates were statistically higher after hysterectomy than after repair. Other etiologic factors were extreme multiparity and an inadequate transfer system to the obstetric centers. A reduction of uterine rupture rates can be achieved by prevention of extreme multiparity (more than 4 deliveries) and of home deliveries and decentralization of obstetric services into peripheral units and villages.

[Evaluating the cervix in pregnancy using vaginal sonography. Studies of cervix insufficiency].

Transvaginal ultrasound provides important detailed information, which cannot be obtained by routine manual vaginal examination. By measuring the outside-inside distance (from os externum to os internum), we can determine the actual length of the cervix. By depicting the cervical canal, we can identify early dilatation. Visualizing the os internum with a possible opening, forming a conus, helps reveal an incompetent cervix. A total of 485 measurements of the cervix was carried out. Fifty patients with normal clinical findings between 28 and 32 weeks of pregnancy were compared to the same number of patients in the 28th to 32nd week of pregnancy, with the clinical diagnosis of an incompetent cervix. A cervical length of 46.3-39.3 mm was found in normal pregnancies, and a length of 34.0-21.4, when a clinically incompetent cervix had been diagnosed, a difference of 12.3-17.9 mm.

[Application of the neodymium-Yag laser in treating adhesions].

The authors conducted an experimental study on the possibilities of application of the "in touch" technique for microsurgical adhesion resection with a Neodymium-Yag laser. It enables good hemostasis and is an alternative to the CO2 laser, the risk of causing vital organ lesions being reduced.

[Tetralogy of Fallot following coumarin administration in early pregnancy--an embryopathy?].

A case report of a 35-year old woman is presented who continued a coumarin therapy unconscious of an early pregnancy up to day 61. At term she delivered a baby with tetralogy of Fallot, up to now not mentioned in the symptom complex of malformations due to a coumarin therapy. In the case presented the typical symptoms of a warfarin embryopathy including a chondrodysplasia punctata and other morphological changes were lacking. Although some cases of cardiac malformations have been reported in literature following coumarin therapy in early pregnancy, a causal connection could not be confirmed.

[Transvaginal echography. An application in the diagnosis of cervical incompetence].

It has already been demonstrated that abdominal ultrasound is an adequate method for measuring the cervix in pregnancy. The use of the vaginal route for such measurement is new. We have been using for the vaginal approach an ultrasound transducer of 5 mHZ with an angle of sweep of 240 degrees. The study was carried out on 23 pregnant women at the 28th week of pregnancy who had been admitted because of threatened premature labour with possible cervical incompetence; and on 20 cases of normal pregnancy also at the 28th week, which is the time when we do glucose estimations normally in our antenatal clinics. The result of our work shows that this ultrasonic method through the vagina gives us much more accurate measurements of the cervix than digital vaginal examination does. A mean difference of 12.3 mm in the length of the cervix was found in normal pregnancies (46.3 mm) and in cases where there was a question of cervical incompetence (34 mm). Furthermore the phenomena of shortening, dilatation of the cervix and a funnel-shape of the internal os are ultrasound signs of value in diagnosing incompetent cervix. Further advantages of the transvaginal approach are that there is no need for the bladder to be filled previously, and that the organs are nearer which improves the ultrasound picture. All the same, it is to be emphasized that transvaginal ultrasound can only be a factor to be added to clinical examination in the diagnosis of the incompetent cervix.
