Aims-To compare the growth of very low birthweight (VLBW) children in early adolescence with that of their normal birthweight peers; to examine the role of factors contributing to growth-parental height, perinatal variables, bone maturity and sexual maturation; to examine the correlation between head growth and cognitive and educational outcome. Methods-Standing and sitting heights, weight, occipito-frontal circumference (OFC), skinfold thicknesses and pubertal staging were assessed in 137 VLBW children and 160 controls at 11-13.5 years of age. Ninety six (70%) of the VLBW children had their bone age assessed using the TW2 method. Reported parental heights were obtained by questionnaire.

The objective of this study was to assess the frequency of testicular microlithiasis (TM) in infertile men who underwent testicular ultrasound and to determine any causative or associated factors. The case notes of 159 consecutive patients who were referred for testicular ultrasound in the investigation of male factor infertility were reviewed. Microcalcification was found in 10 cases (6.2%). This was unilateral in all cases and six patients had clinical evidence of a varicocele. Five cases had minimal calcification and five had marked TM. On patient had a past history of testicular maldescent and another of testicular torsion. Sperm function (as assessed by sperm count, motility and the sperm migration test) was variable within the 10 patients and there was no correlation with hormone profiles or testicular size. There was a statistical difference between a number of investigations in those patients with minimal degrees of calcification and those with TM (sperm migration test (SMT), namely sperm migration and sperm motility (p < 0.05, Mann-Whitney U test)). The results showed a higher than expected incidence of TM. Patients with marked TM seemed to have poorer sperm function than those with minimal calcification. There was a high incidence of co-existing pathology, for instance scrotal varicocele and cryptorchidism, although the numbers in this study were small and further studies need to be carried out to determine the exact nature and significance of this condition.

Bronchopulmonary foregut malformations (BPFM) are a heterogeneous group of pulmonary developmental anomalies that present at varying ages and with overlapping symptoms, signs and radiology. This article discusses the embryology of these lesions with reference to possible common origins and the link between aetiology and radiological appearance. The radiology of each lesion, both antenatally and postnatally, is described and illustrated. A number of quandaries exist in the prediction of prognosis and subsequent treatment of BPFM. We discuss the radiological features that may help to elucidate an individual prognosis and aid in the planning of treatment. The treatment options available for BPFM are briefly discussed. Finally, the link between BPFM, in particular cystic adenomatoid malformations and malignancy, is discussed. We aim to provide a comprehensive overview of the embryology, radiology, prognosis and treatment highlighting contentious issues of BPFM.

The management of isolated fetal choroid plexus cysts remains controversial. We have prospectively studied 15,565 pregnancies at two large obstetric units for the presence of choroid plexus cysts. In all cases where cysts were present at 19 weeks' gestation or greater, and were multiple, bilateral or solitary and greater than 5 mm maximum diameter, women were offered amniocentesis or placental biopsy, irrespective of the presence or absence of other abnormalities. Choroid plexus cysts were present in 152 (0.98 per cent) of cases. Four cases (2.6 per cent) of autosomal trisomy (three of trisomy 18, one of trisomy 21) were detected on prenatal karyotyping. In all cases, choroid plexus cysts were the only detectable prenatal anomaly. This study and a review of other large studies do not support the view that isolated choroid plexus cysts are a benign variant, the risk of trisomy being 1 in 82. Until further evidence is available, we recommend that cases of isolated fetal choroid plexus cysts at 19 weeks' gestation or greater should be offered prenatal karyotyping.

The differential diagnosis of echogenic areas in the fetal chest include congenital diaphragmatic hernia (CDH), cystic adenomatoid malformation (CAM), sequestrated lung and tracheal or bronchial atresia. The purpose of this study was to evaluate the accuracy of prenatal diagnosis and document outcome in fetuses with echogenic chest lesions. Seventeen fetuses with echogenic chest masses were seen in our unit between 17 and 36 weeks' gestation over a 5-year period. We reviewed these cases retrospectively for prenatal diagnosis, postnatal diagnosis and outcome. Prenatal diagnosis was correct in 13 fetuses, with CDH in 8, sequestrated lung in 4 and tracheal atresia in 1. Four fetuses had incorrect or uncertain prenatal diagnoses. In three fetuses CDH and CAM could not be differentiated. After delivery two of these had CDH and one had sequestrated lung. One fetus with bilateral lesions had prenatal diagnosis of bilateral CAM. Post-mortem examination revealed tracheal atresia as part of Fraser syndrome. All five babies with sequestrated lung are well and none required surgery. Ten fetuses had CDH, two pregnancies were terminated, one died in utero, five died as neonates and two babies survived following surgery. The study reveals that in a minority of fetuses CDH and CAM could not be differentiated prenatally. We agree with recent reports of fetal sequestrated lung describing sonographic improvement in utero. A large lesion on initial scan does not necessarily predict a poor neonatal outcome in this condition. This, together with the poor outcome in fetuses with echogenic CDH and tracheal atresia, has important implications for prenatal counselling.
