[Third circulation: twin transfusion syndrome].

The estimated incidence in the Netherlands of serious previable twin-to-twin transfusion syndrome is 50-100 cases per year. The polyhydramnion-oligohydramnion sequence is the most prominent feature. Prognosis without treatment is dismal: previable preterm birth. Risk of serious morbidity in the surviving twin in case of foetal demise of the other is impressive. Once the diagnosis of monochorionicity has been made in the first trimester, detailed ultrasound examination is mandatory for early recognition of the development of the syndrome, as therapeutic options exist. Therapeutic options include piercing of the intertwin membrane, repeated amniocenteses or laser occlusion of the chorionic vasculature. In seven Dutch centres over three years time 61 cases were identified: 36 needed intervention; 63 (of the 122) children survived, 10 with longterm morbidity.

A comparative and longitudinal study on endocrine changes related to ovarian function in patients with anorexia nervosa.

Screening of androgens and estrogens in blood and a GnRH test were performed in 20 female patients with anorexia nervosa and in 10 lean and 10 normal weight healthy control subjects. Both control groups had regular ovulatory menstrual cycles. The investigation was performed in the mid-follicular phase. Several variables showed significant differences between the groups; the levels of PRL, estrone, estradiol, progesterone, testosterone, androstenedione, and LH were lowest in the patients with anorexia nervosa. The lean control group showed intermediate values for progesterone, androstenedione, and, to a smaller extent, testosterone. The FSH response to GnRH was significantly higher in the patient group, corresponding to the pattern of late prepubertal girls. Ten patients were seen in a follow-up study. Five had resumption of the menstrual cycle, and the others still had amenorrhea. The two subgroups did not differ in either weight gain or the basal hormonal variables investigated. After weight gain an increased LH response to GnRH was observed in both subgroups. Patients who had resumption of the menstrual cycle showed a higher response of LH to GnRH, both before and after weight gain. The mean increase in LH after GnRH administration was significantly different between the two subgroups. The results suggest that the GnRH test may be useful to assess the stage of the disease and to predict the outcome, especially with regard to restoration of the menstrual cycle.
