The significance of choroid plexus cysts in fetuses at 18-20 weeks. An indication for amniocentesis?

Over a period of 25 months, all antenatal patients were offered a detailed ultrasound scan at 18-20 weeks' gestation. The lateral cerebral ventricles were scanned for the presence of choroid plexus cysts. Fifty-one patients found to have choroid plexus cysts were offered amniocentesis to exclude chromosomal abnormalities. One pregnancy, in which the only abnormality found was bilateral choroid plexus cysts, was terminated after trisomy 18 was detected on amniocentesis at 19 weeks. The other 50 pregnancies had normal fetal outcomes. The significance of the isolated finding of choroid plexus cysts is reviewed.

Prenatal diagnosis of Conradi's syndrome. Case report.

A case is described of the diagnosis by ultrasound scanning during the second trimester of Conradi-Hünermann's syndrome (asymmetrical rhizomelic limb shortening or chondrodysplasia calcificans punctata). The prenatal diagnosis of limb shortening deformities is discussed.

Pregnancy outcome in elderly primigravidae with and without a history of infertility.

The pregnancy outcome of 196 primigravidae aged 35 years or over, with no history of involuntary infertility, was compared with that of 196 matched primigravidae aged 20-25 years, and also with 72 'elderly' primigravidae (greater than or equal to 35 years) whose pregnancies had followed a period of involuntary infertility of at least 1 year. The older primigravidae with no history of infertility had a four-fold risk of preterm (less than 37 weeks) delivery, a five-fold risk of caesarean section and significantly increased rates of vaginal operative delivery, chronic hypertension and fibroids, when compared with the primigravidae between 20 and 25 years of age. They also showed a greater tendency to severe preeclampsia and perinatal death, but these differences were not statistically significant. Elective caesarean section was twice as common in the older women with a history of infertility than in those without such a history (20.8% compared with 10.7%) although this difference was not statistically significant. No other differences in pregnancy outcome were found between the two 'elderly' groups.

Prophylactic blood transfusion in maternal sickle cell syndromes.

An assessment of the benefits of prophylactic blood transfusion during 51 pregnancies in women with haemoglobin SS, haemoglobin SC and haemoglobin S-beta-thalassaemia in a retrospective study from 1978 to 1984 has failed to demonstrate any clear conclusions as to their efficacy. Of the transfused patients, 22% developed atypical red cell antibodies and 14% had immediate minor transfusion reactions. Our data show no significant difference in fetal or maternal outcome between those patients who were transfused prophylactically and those who were not. A prospective study to clarify the appropriate place of this important aspect of management in women with sickle cell disease in pregnancy is suggested.

The effects of subcutaneous hormone implants during climacteric.

Climacteric symptoms in 120 women were treated with a total of 469 hormone implants (oestradiol 50 mg and testosterone 100 mg) over a period of four years. All patients with a uterus were given an oral progestogen to prevent endometrial hyperplasia. There was a marked response to treatment, hot flushes being improved in all patients, depression in 99% and loss of libido in 92%. Patient acceptability of this type of treatment was good and there were few side effects or complications. After therapy, the serum oestradiol exceeded the serum oestrone but remained within normal limits. When climacteric symptoms returned and re-implantation occurred the serum levels of oestrone, oestradiol, luteinising hormone (LH), follicle stimulating hormone (FSH) and testosterone were within the normal range for the reproductive age. This indicates that the return of symptoms is due to a change in the hormone levels rather than absolute hypo- oestrogenism .

Obstetric characteristics in different racial groups.

A detailed analysis of 2632 consecutive pregnancies in white, black and Asian women, who were delivered during the period 1978 to 1980, found significant differences between the three ethnic groups. Asian primiparae had the longest first and second stages of labour, with the highest incidence of prolonged latent phase (14%) and primary dysfunctional labour (30%). Black primiparae and multiparae had the highest incidence of secondary arrest in the first stage of labour (10% and 4% respectively) and of primary dysfunctional labour, with the greatest recourse to emergency caesarean section (13% and 4% respectively). The mean birthweight for singletons born between 37 and 42 weeks was 3.37 kg for white babies, 3.25 kg for black babies and 3.14 kg for Asian babies. There was no racial difference in perinatal mortality or morbidity in this survey.

Pregnancy in women with sickle cell trait.

The complications and outcome of 334 pregnancies in women with sickle cell trait between 1975 and 1981 are reviewed. The perinatal mortality rate was 6 per 1000. The main maternal complications were recurrent urinary tract infections (6%) and haematuria (16.5%). Fetal distress in labour was seen in 17% and 11.5% were delivered by emergency caesarean section. Compared with a comparable group of women without sickle cell trait, the mean birthweight of the babies (3202 g) was not reduced. The mean age of the mothers (25 years), their mean parity (1.46) and the percentage who were para 4 or more (13%) were all significantly increased, with important implications for the continuing transmission of the sickle cell gene.

Pregnancy in sickle cell disease in the UK.

The complications and outcome of 125 pregnancies in women with sickle cell disease between 1975 and 1981 are reviewed. There were no maternal deaths, but a perinatal mortality rate of 48 per 1000. The main maternal complications were sickling crises (38%), anaemia (65%), infections (61%) and severe pregnancy-induced hypertensive disease (5%). There were three patients with eclampsia. There was a 13% spontaneous preterm delivery rate, 25% of the babies were 'light-for-dates', fetal distress in labour was seen in 24% and 15% were delivered by caesarean section. There was an increased incidence of involuntary infertility and spontaneous abortion. The treatment by prophylactic blood transfusions is discussed.

Unilateral renal hypoplasia as an incidental finding in a patient with a ruptured heel cord.

A report of unilateral renal hypoplasia in an 11-year-old patient, admitted to the hospital for surgical repair of a ruptured Achilles tendon, is presented. The condition was incidentally discovered because of an elevated blood pressure level. The case demonstrates that screening for hypertension, even in the pediatric population, should be an essential part of the routine podiatric physical examination.
