An unselected series is presented of 17 infants born to epileptic mothers and exposed to sodium valproate during pregnancy. Nine infants had minor abnormalities and of these infants five also had major malformations, described as the 'fetal valproate syndrome'. The most frequent malformation was congenital heart disease. Nine of the infants had manifestations of withdrawal, such as irritability, jitteriness, abnormalities of tone, seizures, and feeding problems. Four of these infants had an unrelated hypoglycaemia. The frequency of withdrawal symptoms was significantly related to the dose of valproate given to the mothers in the third trimester, and there was a tendency for both the frequency of the minor abnormalities and the major malformations to be related to the valproate dosage in the first trimester.

Obesity in adolescents is prevalent worldwide. Polycystic ovary syndrome (PCOS) is often associated with obesity in women, and it has serious metabolic and reproductive health implications. Although PCOS does not become clinically visible until early adolescence, its origins are likely much earlier. Therefore, we reviewed the recent literature regarding the mechanisms linking the development of PCOS and obesity in adolescent girls. We found that excess abdominal adipose tissue (AT) initiates metabolic and endocrine aberrations that are central in the progression of PCOS. As an example, abdominal AT impairs insulin action, which interacts with the progression of hyperandrogenism. In addition, excessive androgen levels lead to impaired glucose uptake, which also contributes to insulin resistance, which again increases the deposition of visceral fat. The body composition is influenced by testosterone, which decreases subcutaneous fat lipolysis and influences adipocyte distribution. These mechanisms may explain why PCOS girls have an increased visceral adipose mass independent of body mass index. Therefore, first-line treatment in adolescent PCOS is often lifestyle intervention to prevent the damaging effects of obesity. Pharmacological treatment of adolescent PCOS is not standardized because the long-term effects in adolescents have not yet been evaluated; therefore, drugs should be prescribed cautiously. Although the complex metabolic interrelationships between obesity and PCOS have yet to be fully understood, the co-occurrence of these conditions in adolescent girls tends to increase the severity of the negative health consequences of each condition.

We have conducted a modified double-blind study on the effect of human chorionic gonadotropin (hCG), gonadotropin releasing hormone (GnRH) and placebo on bilateral and unilateral maldescended testes. One hundred and fifty-five boys with bilateral and 88 boys with unilateral cryptorchidism fulfilled the inclusion criteria and completed the treatment protocol. The boys were between 1 and 13 years of age. hCG was administered as intramuscular injections twice weekly for 3 weeks. GnRH and placebo were given intranasally. hCG was superior to GnRH and placebo in the treatment of bilateral maldescended testes (p = 0.0009). Both testes descended in 25% of the boys following treatment with hCG, and improvement in the position of the testes was obtained in a further 25 % of the cases. hCG administration resulted in complete testicular descent in 14% of boys with unilateral cryptorchidism compared with 3 and 0% after placebo and GnRH, respectively (p = 0.07). The testis had moved to a more distal position in 46 % of the boys treated with hCG. There was no significant difference between the treatment groups with regard to age or initial position of the testes. We conclude that a success rate of 25% justifies the use of hCG in the treatment of maldescended testes, whereas the study did not support a general use of GnRH administered intranasally.
