Eclampsia, the occurrence of a convulsion in association with pre-eclampsia, remains a rare but serious complication of pregnancy. A number of different anticonvulsants are used to control eclamptic fits and to prevent further fits. ⋯ Magnesium sulphate appears to be substantially more effective than diazepam for treatment of eclampsia.

Review Meta AnalysisInsulin-sensitising drugs (metformin, troglitazone, rosiglitazone, pioglitazone, D-chiro-inositol) for polycystic ovary syndrome.
Polycystic ovary syndrome (PCOS) is characterised by anovulation, hyperandrogenaemia and insulin resistance. Hyperinsulinaemia is known to be associated with an increase in cardiovascular risk and the development of diabetes mellitus. If insulin sensitising agents such as metformin are effective in treating features of PCOS, then they could have wider health benefits than just treating the symptoms of the syndrome. ⋯ Metformin is an effective treatment for anovulation in women with PCOS. Its choice as a first line agent seems justified, and there is some evidence of benefit on parameters of the metabolic syndrome. Ovulation rates are higher when combined with clomifene (76% versus 46% when used alone), but there is no evidence to indicate whether there is an increased multiple pregnancy rate with this combination. There is no data regarding its safety in long-term use in young women. It should be used as an adjuvant to general lifestyle improvements, and not as a replacement for increased exercise and improved diet.

Review Meta AnalysisLow dosage tricyclic antidepressants for depression.
Tricyclic antidepressants are still extensively prescribed worldwide. Evidence for the recommended dosage of tricyclics, however, is poor. ⋯ Treatment of depression in adults with low dose tricyclics is justified. However, more rigorous studies are needed to definitively establish the relative benefits and harms of varying dosages.

Review Meta AnalysisColony stimulating factors for chemotherapy induced febrile neutropenia.
Febrile neutropenia is a frequent event for cancer patients undergoing chemotherapy and it is potentially a life threatening situation. The current treatment is supportive care plus antibiotics. Colony stimulating factors (CSF) are cytokines that stimulate and accelerate the production of one or more cellular lines in bone marrow. Some clinical trials addressed the question of whether the addition of CSF to antibiotics (ATB) could improve the outcomes of patients with febrile neutropenia. The results of these trials are conflicting and no definitive conclusion could be reached. ⋯ The use of CSF in patients with febrile neutropenia due to cancer chemotherapy does not affect overall mortality, but reduces the amount of time spent in hospital and the neutrophil recovery period. It was not clear whether CSF has an effect on infection-related mortality.

It has been estimated that about ten per cent of children between six and 20 years of age suffer from migraine. It is estimated that children with migraine lose one and a half weeks more schooling per year than their peers. Prophylactic drugs can be prescribed when children suffer from frequent or disabling headaches. ⋯ Only one study each for propranolol and flunarizine were identified showing efficacy of these drugs as prophylactics of paediatric migraine. Nimodipine, timolol, papaverine, pizotifen, trazodone, L-5HTP, clonidine, metoclopramide, and domperidone showed no efficacy in reduction of frequency of attacks. Available studies on other commonly used drugs failed to meet our inclusion criteria. The quality of evidence available for the use of drug prophylaxis in paediatric migraine was poor. Studies were generally small, with no planning of sample size, so that for many drugs, despite the negative findings of this review, we do not have conclusive evidence of 'no effect'. There is a clear and urgent need for methodologically sound RCTs for the use of pings of this review, we do not have conclusive evidence of 'no effect'. There is a clear and urgent need for methodologically sound RCTs for the use of prophylactic drugs in paediatric migraine, starting with propranolol. These studies need to be adequately powered to investigate meaningful reductions in pain and suffering from a patient's perspective.
