Review Meta AnalysisPharmacotherapy for anxiety disorders in children and adolescents.
Anxiety disorders are a potentially disabling group of disorders which are prevalent in childhood and adolescence. The recognition of the early onset of anxiety disorders, and their successful treatment with medication in adults, has led to the growing interest in using medication for paediatric anxiety disorders. ⋯ Medication treatments can be effective in paediatric anxiety disorders, acting to reduce core symptoms, and should be considered as part of the treatment of these disorders. The greatest number of trials showing efficacy to date have assessed the SSRIs in treating paediatric OCD.There is no clear evidence to show that any particular class of medication is more effective or better tolerated than any other. As quantitative data was only available for the SSRIs and venlafaxine the routine use of benzodiazepines cannot be recommended, especially given concerns of dependency and treatment -related emergent adverse events associated with this class of drugs.Future RCTs could help identify potential clinical moderators of treatment efficacy. Studies of the long-term efficacy of medication treatment, optimal dosage, as well as direct comparisons of pharmacotherapy and psychotherapy are also warranted.

Acute ischaemic stroke is a common cause of death and disability. A number of studies published in China have shown that acanthopanax is beneficial for acute ischaemic stroke. ⋯ The risk of bias in all the included trials was high, and hence the data were not adequate to draw reliable conclusions about the efficacy of acanthopanax in acute stroke. Much larger trials of greater methodological quality are needed.

Review Meta AnalysisErythropoietin as an adjuvant treatment with (chemo) radiation therapy for head and neck cancer.
Tumour hypoxia increases tumour invasiveness and has a negative impact on response to therapy. Hypoxic tumours are also associated with severely anaemic individuals. It has therefore been hypothesised that correcting anaemia, by increasing haemoglobin levels using erythropoietin, improves tumour oxygenation and consequently the patient's prognosis. ⋯ There are strong suggestions that RT plus EPO has a negative influence on outcome as opposed to RT alone. However, the target haemoglobin concentration, which was higher than recommended in four of the five included RCTs, may have had a significant role. Nevertheless, based on these findings EPO should not be administered as an addition to RT outside the experimental setting for patients with head and neck cancer.

Review Meta AnalysisInterventions in the management of serum lipids for preventing stroke recurrence.
Studies have shown that interventions which reduce total and low-density lipoprotein cholesterol levels also reduce coronary heart disease (CHD) and stroke events in those with a history of CHD. However, it is uncertain whether treatment to alter cholesterol levels can prevent recurrence of either stroke or subsequent cardiovascular events and whether differences in outcomes exist between classes of lipid-lowering therapy. This is an update of a Cochrane review first published in 2002. ⋯ There is evidence that statin therapy in patients with a history of ischaemic stroke or TIA significantly reduces subsequent major coronary events but only marginally reduces the risk of stroke recurrence. There is no clear evidence of beneficial effect from statins in those with previous haemorrhagic stroke and it is unclear whether statins should be started immediately post stroke or later. In view of this and the evidence of the benefit of statin therapy in those with a history of CHD, patients with ischaemic stroke or TIA, with or without a history of established CHD, should receive statins.

Review Meta AnalysisSurgical approach to hysterectomy for benign gynaecological disease.
The three approaches to hysterectomy for benign disease are abdominal hysterectomy (AH), vaginal hysterectomy (VH), and laparoscopic hysterectomy (LH). Laparoscopic hysterectomy has three further subdivisions depending on the part of the procedure performed laparoscopically. ⋯ Because of equal or significantly better outcomes on all parameters, VH should be performed in preference to AH where possible. Where VH is not possible, LH may avoid the need for AH however the length of the surgery increases as the extent of the surgery performed laparoscopically increases. The surgical approach to hysterectomy should be decided by the woman in discussion with her surgeon in light of the relative benefits and hazards.
