Sensing glucose concentrations at GHz frequencies with a fully embedded Biomicro-electromechanical system (BioMEMS).

The progressive scaling in semiconductor technology allows for advanced miniaturization of intelligent systems like implantable biosensors for low-molecular weight analytes. A most relevant application would be the monitoring of glucose in diabetic patients, since no commercial solution is available yet for the continuous and drift-free monitoring of blood sugar levels. We report on a biosensor chip that operates via the binding competition of glucose and dextran to concanavalin A.

[Discordant growth of multiple fetuses in combination of HELLP syndrome and single umbilical artery in a triplet fetus].

We present a case of a triplet with HELLP-Syndromin the 31st gestation week. In ultrasound one of the fetuses was to small for gestational age and one of them showed an zero-flow in Doppler ultrasound. We decided to deliver by Caesarean section in the 31st gestation week.

[Urethral wall pulsation in pregnant patients, continent and stress incontinent females].

The amplitudes of urethral vascular pulsations in pregnant women, continent and urinary stress incontinent women were compared with each other. Significant differences have been found in the chi 2-Test. In pregnant women the mean pulsation amplitude was 1.

[A modified Sarafoff suture for closure of the uterine wound in Cesarean section].

Using a retrospective investigation the authors demonstrate the advantage of the modified Sarafoff-suture (a one layer suture of the myometrium) in comparison with the two-layer suture. The results shows a lower rate of febrile courses, less postoperative complications and a shorter hospital stay. The first clinical experiences showed less scar complications in the courses of vaginal delivery in patients with a previous caesarean section.

[The rectal-digital fetal stimulation test--an alternative to fetal blood analysis?].

The rectal-digital fetal stimulation test (FST) is outlined. The indications of FST are the same as for the fetal scalp, blood sampling (FBA). Our clinical experiences suggested, that the fetal scalp blood sampling rate may be reduced by 50% using FST.

[Intra-uterine pressure measurements during early pregnancy using endoradioprobes].

The intrauterine pressure was determined by means of endoradiosonde in 42 pregnant women before induced abortion. It was measured the tonus and after stimulation with oxytocin the liminal value the basic tonus and the highest increase of pressure. The values of pressure were higher after artificial rupture of the amnion than before.
