Outcome of pregnancy in women with cystic fibrosis.
BACKGROUND: As women with cystic fibrosis are living longer, pregnancy is becoming increasingly common. The combined experience of pregnancies in women with cystic fibrosis from adult centres in the Midlands and North of England has been examined. METHODS: A retrospective study of the case notes of 22 pregnancies in 20 patients with cystic fibrosis examined changes in lung function, body weight, and microbiological status during the course of pregnancy. Duration of pregnancy, birth weight, and maternal survival were amongst other variables studied. The relation between values before pregnancy and important outcome measures were examined. RESULTS: Eighteen of 22 pregnancies were completed producing healthy, non-cystic fibrosis infants (12 female). Mothers lost 13% of FEV1 and 11% of FVC during pregnancy, most of which was regained. Body weight changes were variable, but most mothers gained weight (mean weight gain 5.7 kg). Microbiological status remained unchanged. Six infants were preterm and two were light for dates. Four mothers died up to 3.2 years following delivery. Of the prepregnancy parameters examined, %FEV1 showed the best correlation with maternal weight gain, gestation, birth weight, and maternal survival. CONCLUSIONS: Pregnancy was well tolerated by most mothers with cystic fibrosis although those with moderate to severe lung disease (%FEV1 < 60%) before pregnancy fared worse, producing preterm infants and suffering increased loss of lung function and mortality compared with mildly affected mothers. Prepregnancy %FEV1 appears to be the most useful predictor of important outcome measures in pregnancies in women with cystic fibrosis.

Clinical and pathological factors in spontaneous abortion following chorionic villus sampling.
Twenty-nine cases of spontaneous abortion following first-trimester chorionic villus sampling (CVS) were reviewed out of a series of 722 patients. Of the 29 cases, there were only four abnormal CVS results. Pathological examination was performed in 79 per cent of cases, and this did not identify any characteristic pathological feature associated with spontaneous abortion after CVS. There was no obvious difference in the pathological features following the transabdominal (TA) or the transcervical (TC) methods. The majority of miscarriages occurred within 4 weeks of the procedure, but 38 per cent of cases aborted between 7 and 14 weeks after CVS. The TC method was used in 22 patients; the TA in 6; and both methods in 1 patient. The TA method was associated with a significantly lower fetal loss rate than the TC method (TA 2 per cent, TC 9 per cent, p less than 0.001).

Patients' attitudes following chorionic villus sampling.
The attitudes of 190 patients who had undergone chorionic villus sampling (CVS) were assessed by means of a questionnaire. One hundred and fifty-two patients replied of whom 68 (45 per cent) were referred because of increased maternal age and in the other 84 cases the indications included previous chromosomal abnormalities, fetal sexing, DNA analysis, and biochemical analysis. One hundred and twenty-two patients had a transcervical procedure, 24 had a transabdominal, and six patients required both procedures. One hundred and forty-one patients (93 per cent) reported CVS to be a satisfactory procedure, and the same percentage thought earlier diagnosis was beneficial. Thirty-nine patients (81 per cent) reported a better experience with CVS than with a previous amniocentesis. A majority of patients (93 per cent) wished a CVS in a future pregnancy and 137 patients (97 per cent) would accept a risk of miscarriage from the procedure of twice that quoted for amniocentesis (1 per cent).

Direct and short-term culture preparation of chorionic villi. Is any one method best?
Chorionic villi from 20 diagnostic cases were prepared for cytogenetic analysis by a direct and two short-term culture methods. No significant differences were found between the methods in the quality and quantity of metaphases obtained. A further study using villi from 20 pre-termination patients indicated an inherent variation in the quality of villi resulting in inconsistent processing and variation in the response of a sample to the methods. This suggests that it would be advantageous to process the villi by more than one method.

A study comparing transcervical with transabdominal chorionic villus sampling (CVS).
Chorionic villus sampling (CVS) was performed in 50 anaesthetized patients before therapeutic abortion by the transabdominal route and then by the transcervical route. The two methods of villus sampling were equally successful in obtaining villi but the transcervical method was significantly better at obtaining chorionic villi greater than 10 mg in weight (chi 2 13.92 P less than 0.001). Placental position did not affect villus recovery with either sampling method.

Spontaneous abortion rate in ultrasonographically viable pregnancies.
In a prospective study of 500 patients who had an ultrasonically viable pregnancy at less than 12 weeks' gestation, the spontaneous abortion rate was 2% overall. In those women with a history of spontaneous abortion, the abortion rate increased tenfold. Spontaneous abortion at less than ten weeks' gestation was up to three times higher than that at greater than ten weeks' gestation; this may have implications when deciding on the timing of first-trimester diagnostic procedures.

Day-to-day mood changes after childbirth: further data.
The depression and lability of mood which have been previously reported on the fifth day after childbirth are largely restricted to women with high neuroticism scores. The pattern of day-to-day mood changes is the same after Caesarian section as after vaginal delivery, but there is no 'day five' phenomenon after hysterectomy. Post-partum mood disturbance is less prominent in women who return home 48 hours after delivery.
