Two cases of cervical pregnancy (CG) are mentioned with description of the clinical course and diagnosis. Treatment of CG is total hysterectomy in approximately 70% of the cases while the remaining 30% are treated conservatively. The maternal mortality is practically zero today whereas it was 40% in 1911.
A case of chorioangioma of the placenta is reported in which the tumor and a few of its maternal and fetal complications were detected by antenatal ultrasound examination. The clinical implications of this benign tumor for both mother and fetus are discussed.
Sixteen women had intrauterine devices (IUDs) with retracted threads. If an IUD with retracted thread is located within the uterus or intramurally, hysteroscopic removal is advisable. If it is located intraabdominally, laparoscopic removal is recommended.
With the object of examining the diagnostic accuracy of and pain reaction to endocervical curettage (ECC) either by using a new instrument, Vabra mc cervix, or with a conventional 3 mm metal curette, 298 patients with histologically verified cervical intraepithelial neoplasia (CIN) or cytological suspicion have been involved in a consecutive prospective randomized trial. One hundred and forty-eight patients underwent curettage with the Vabra instrument (vabrasio) followed by conventional curettage; 150 underwent the same procedure, but in reverse order. In 114 patients, CIN was ascertained in one or both trials. Vabra mc cervix found normal histology in 23 of these patients (20%), whereas conventional curettage showed normal histology in 58 patients (51%). Quantitatively, Vabra mc cervix extracted significantly more tissue material than did conventional curettage. The pain intensity when using of Vabra mc cervix was less severe. The present study showed diagnostic accuracy of Vabra mc cervix to be 80% (95% confidence limits: 63.38-80.73), compared with 49% (95% confidence limits: 35.17-54.35) when using conventional curettage.
A randomized doubleblind investigation of prostaglandin vaginal suppositories prior to hysteroscopy was undertaken in 30 non-pregnant women. PGE2 in 14 of 15 treated patients we found a softening and a dilatation of the cervical canal, but with a relatively high frequency of side effects-nausea, vomiting and diarrhea. No serious bleeding or side effects were observed.

A female infant with extralobar lung sequestration (ELS) combined with bilateral hydrothorax and ascites is presented. A 34-year-old para II, pregnant in the 29th gestation week, was referred to hospital because of acute hydramnios. Ultrasound examination demonstrated marked hydramnios, together with ascites and bilateral pleural effusion in the fetus. In the amniotic fluid, alfafetoprotein was found normal and the karyotype showed a normal chromosome pattern, 46 xx. The hydramnios was so severe and the cervix so unripe, that cesarean section had to be undertaken, and a girl of 1650 g, and 42 cm long was born. Just after delivery the infant had bradycardia, cyanosis and respiratory insufficiency, with Apgar score 2 during the first 15 min. Manual ventilation followed by Servo respirator with 100% oxygen was given, but with poor effect. The infant lived only 6 3/4 hours. At autopsy there was hydrothorax, bilateral collapsed lungs and ascites and ELS as the only congenital malformation.
