In 13 patients with anorexia nervosa (AN), secondary amenorrhoea lasting eight to 25 months and the loss of body weight more than 25% were found. Estradiol concentrations (E2) were significantly lower in patients with anorexia nervosa than in nine patients in the control group (21.4 +/- 9.2 vs 96.5 +/- 25.8 pg/ml, p less than 0.01). LH concentrations were also significantly lower in AN than in the control group (6.8 +/- 3.2 vs 12.3 +/- 4.5 IU/L, p less than 0.01). A similar relationship was found in the FSH concentration (5.2 +/- 2.0 vs 9.4 +/- 3.5 Iu/L, p less than 0.05). A 100 ug LH-RH i.m. administration produced a significant rise of the LH concentration and a slightly smaller one of FSH in comparison with the basal concentrations, with a maximum rise after 60 minutes (LH after 60 minutes 76.4 +/- 16.5 IU/L, and FSH 24.0 less than 5.6 IU/L).

In 126 pregnant women of the gestational age from the 28th to the 44th gestational week, the biparietal diameter, the abdomen diameter, and the placental maturity after Granum et al. were determined. Amniocentesis was performed for obstetric indication. Also the L/S ratio and the cytological estimation of the gestational age were recorded. The first degree of the placental maturity was found in 37, the second degree in 3, and the third degree in 36 pregnant women. In the first group, BPP was 8.38 +/- 0.75, the abdomen diameter 8.30 +/- 0.63, and pulmonary maturity in 73% of women according to the L/S ratio and in 91.9% according to cytological estimation. In the second group, BPP was 9.15 +/- 0.65, the abdomen diameter 9.03 +/- 0.83, and in 77.9% of women the L/S ratio was higher than 2 but in 56.6% of women, according to cytological estimation, there was a good pulmonary maturity. At the third degree of placental maturity, BPP was 9.49 +/- 0.60, the abdomen diameter 9.63 +/- 0.92, and a good pulmonary maturity in 94.4% of women. The RDS was not observed in 5.6% of newborns with the L/S ratio below 2. According to cytological estimation, BPP below 9.15 was found in pre-term labour and higher than 9.15 in at-term births when in 94% of women the L/S ratio was higher than 2.

A comparison was made between ultrasound and clinical findings in 45 patients with patients with adenomyosis. In patients with ovarian endometriosis ultrasound showed a cystic ovarian endometriosis ultrasound showed a cystic ovarian tumour in 27 patients, a mixed ovarian tumour in 5 patients, and a solid ovarian tumour in 3 patients, then polycystic ovaries in 5 patients, while in 4 patients the ultrasound finding was negative. In patients with adenomyosis, ultrasound suggested an uterus metriticus 9 times, a myoma 5 times, while cystic islets in the myometrium were found in two cases. The findings described are not specific to endometriosis.

In addition to being the best method for the diagnosis of the hydatidiform mole, ultrasound is also used in the surgical treatment of the mole. The procedure of the evacuation of the complete hydatidiform mole by vacuum suction and continuous ultrasonic monitoring is described. The method is illustrated by three cases.
