[Selective pregnancy termination by minor section in the 24th week in a discordant twin pregnancy and the spontaneous birth of a healthy child at term].

In a twin pregnancy of a 25-year-old woman one fetus was a normal male, while the other had hydrocephalus (6 mm thick pallium in the 23rd week) and a neural-tube defect in the thoracic-lumbar region. The abnormal fetus was removed by minor section in the 24th week, after which the normal one developed without complication. A healthy boy, weighing 3050 g and 52 cm long, was delivered spontaneously in the 39th week. Palpation of the uterus revealed a dehiscence, covered by muscle, in the region of the uterotomy scar, but it required no revision.

[Results of invasive and pharmacosonographic studies in pregnancy (I)].

In prenatal diagnosis besides radiographic methods there is a growing trend towards the use of invasive diagnostic techniques. These techniques have proved to be suitable for early detection of genetically determined conditions, diseases, and malformations of different origin. Invasive examination techniques were applied to 1.104 cases of prenatal diagnosis at Humboldt-University, Berlin, School of Medicine (Charité), Department of Gynaecology and Obstetrics, from January 1st, 1985, up to September 30th, 1987. In this paper importance and possible applications of these methods have been reported.

[Results of invasive and pharmacosonographic studies in pregnancy (II: Amniofetography)].

Prenatal diagnosis of fetal diseases and malformations, using invasive techniques is outlined in this paper. The value of amniofetography under present conditions is discussed together with the use of drugs both isolated and in conjunction with fill-up of the amniotic cavity. Indications for puncture of fluid-filled body cavities, with reference being made to patients looked after at the Humboldt-University Berlin, School of Medicine (Charité), Department of Gynaecology and Obstetrics, from 1985 up to 1987, are reported, too.

[Intrauterine exchange transfusion in Rh immunization].

Intra-uterine exchange transfusion was performed on a patient in the 30th week of gestational age for Morbus haemolyticus fetalis. The indication for intra-uterine intervention resulted from spectrophotometric investigation of amniotic fluid which had revealed Zone III according to Liley as well as incipient hydropic development and development of ascites. The pregnancy had to be terminated for pathological CTG, four days after therapy. Postnatal neonatological intensive therapy included two exchange transfusions, before the child was dismissed in clinically intact condition.

[Perinatal medicine study group. Diagnosis and therapy of ventral schistasis].

Reported in this paper are twelve cases of ventral schistasis transferred for cooperative prenatal assessment, diagnosis, and therapy to the Berlin Charité Hospital of Gynaecology and Obstetrics in 1985 and 1986. Concomitant malformations were recorded from eight in ten omphaloceles. Three of these children were delivered on full term by spontaneous parturition or caesarean section. They were surgically treated immediately after birth. Gastroschisis was recorded from two pregnancies with ventral schistasis. No generally valid recommendation can be given for approach to ventral schistasis. The approach should rather be interdisciplinary and should be preceded by careful diagnosis. Parents should be involved in decision-making.

[Modification of the spectrum of neonatal surgery by prenatal diagnosis].

Expansion of prenatal diagnosis will alter the spectrum of neonatal surgery. The ethos of the medical profession calls for decision in favour of the mother, whenever evidence can be produced to the effect that a severely damaged or nonviable foetus may endanger the health of the pregnant woman. Humanistically and legally warranted termination of pregnancy in such cases will reduce the number of severely malformed newborns on whom nothing can be done but palliative treatment. Early detection of foetal diseases will enable, on the other hand, well-timed preparation of acutely necessary life-saving interventions and will bring down the rate of emergency operations on newborns.

[Comparison of the results of the measurement of O2 consumption with a conventional bacteriologic method for urine obtained by bladder puncture].

A method is described which utilizes the O2 consumption of aerobes and facultative aerobes from urinary tract infections for their detection. Urines obtained by puncture and the corresponding midstream urines were examined for verification. Irrespective of secondary contamination and the presence of non-causative organisms, the O2 consumption method permits the detection of a bacterial urinary tract infection within 1 h. When this method was used, a comparison between midstream urine and urine obtained by puncture showed a complete coincidence. The O2 method has shown a sensitivity of 96.9% at a specificity of almost 100% for bacterial concentrations of more than 10(5)/ml in the urine obtained by puncture.

The role of Ureaplasma urealyticum in urinary tract infections. Demonstration of antibodies against ureaplasmas in the urine.

This study reports the presence of antibodies against Ureaplasma urealyticum in the urine in 17.2% (85) of 493 patients with chronic pyelonephritis. At the same time in 37 of antibody-positive urine samples evidence was found of cultivated Ureaplasma urealyticum, other bacterial germs were isolated infrequently. These culturally and serologically positive urine samples mostly showed pathologic findings of urine sediments. These results led us to believe in a possible involvement of the Ureaplasmas in keeping inflammation processes in the upper urinary tract.

[Cultural and serologic studies of the colonization of mycoplasmas in hemodialysis and kidney transplant patients].

According to the present investigations the frequency of the proof of mycoplasms in the urine of haemodialysed patients and patients who underwent renal transplant operations does not differ from that of healthy control persons. A routine proof of mycoplasms is not proved necessary for the groups of patients examined. The standardisation of the plasms of urea--of patients with different pictures of a disease--resulted in a dominance of the Serovar III. No relation could be seen between Serovar and haemadsorption ability of the plasms of urea. The haemadsorption rate was significantly higher in isolates of patients than in isolates of healthy persons.
