Progesterone, a female sex hormone, is known to induce secretory changes in the lining of the uterus essential for successful implantation of a fertilized egg. It has been suggested that a causative factor in many cases of miscarriage may be inadequate secretion of progestogens. Therefore, progestational agents have been used, beginning in the first trimester of pregnancy, in an attempt to prevent spontaneous miscarriage. ⋯ There is no evidence to support the routine use of progestogen to prevent miscarriage in early to mid pregnancy. However, further trials in women with a history of recurrent miscarriage may be warranted, given the trend for improved live birth rates in these women and the finding of no statistically significant difference between treatment and control groups in rates of adverse effects suffered by either mother or baby in the available evidence.

Review Meta AnalysisGonadotrophin-releasing hormone analogues for endometriosis: bone mineral density.
Gonadotrophin-releasing hormone analogues (GnRHas) are generally well tolerated, and are effective in relieving the symptoms of endometriosis (Prentice 2003). Unfortunately the low oestrogen state that they induce is associated with adverse effects including an acceleration in bone mineral density (BMD) loss. ⋯ Both danazol and progesterone + oestrogen add-back have been shown to be protective of BMD, while on treatment and up to six and 12 months later, respectively. However, by 24 months of follow-up there was no difference in BMD in those women who had HRT add-back. Studies of danazol versus GnRHa did not report long-term follow-up. The significant side effects associated with danazol limit its use.

Review Meta AnalysisValproate for acute mood episodes in bipolar disorder.
Bipolar disorder is a common debilitating illness, characterised by acute affective episodes with full or partial inter-episode remission. Effective and acceptable treatment of acute episodes is required. Valproate has become a leading adjunctive and alternative mood stabilising treatment to lithium in bipolar disorder. ⋯ There is consistent, if limited, evidence to suggest that valproate is an efficacious treatment for acute mania. Valproate may be less effective than olanzapine but may cause less sedation and weight gain. More well designed, randomised controlled trials investigating the relative efficacy and acceptability of valproate in the treatment of the full range of acute affective episodes occurring in bipolar disorder are required.

Review Meta AnalysisIntravenous immunoglobulin for the treatment of Kawasaki disease in children.
Kawasaki disease is the most common cause of acquired heart disease in children in developed countries. The coronary arteries supplying the heart can be damaged in Kawasaki disease. The principal advantage of timely diagnosis is the potential to prevent this complication with early treatment. Intravenous immunoglobulin (IVIG) is widely used for this purpose. ⋯ Children fulfilling the diagnostic criteria for Kawasaki disease should be treated with IVIG (2 gm/kg single dose) within 10 days of onset of symptoms.

Review Meta AnalysisSteroid therapy for meconium aspiration syndrome in newborn infants.
Meconium aspiration syndrome may cause severe respiratory distress in the newborn infant, with an associated high morbidity and mortality. A chemical pneumonitis is believed to occur secondary to bile, bile acids and pancreatic secretions contained in meconium. It has therefore been hypothesised that corticosteroids may be of benefit in the management of this condition through their anti-inflammatory properties. ⋯ At present, there is insufficient evidence to assess the effects of steroid therapy in the management of meconium aspiration syndrome. A further large randomised controlled trial assessing potential benefits and harm would be required to determine its role.
