Review Meta AnalysisInterventions for treating tuberculous pericarditis.
Tuberculous pericarditis - tuberculosis infection of the pericardial membrane (pericardium) covering the heart - is becoming more common. The infection can result in fluid around the heart or fibrosis of the pericardium, which can be fatal. ⋯ Steroids could have important clinical benefits, but the trials published to date are too small to demonstrate an effect. This requires large placebo controlled trials. Subgroup analysis could explore whether effusion or fibrosis modify the effects. Therapeutic pericardiocentesis under local anaesthesia and pericardiectomy also require further evaluation.

ReviewFibrinolytic therapy for intraventricular hemorrhage in adults.
Spontaneous or secondary intraventricular hemorrhage is a marker of poor prognosis for hemorrhagic stroke. It can cause hydrocephalus and require ventricular shunt placement, result in permanent neurological deficits or death. Fibrinolytic agents injected into the ventricular system could dissolve blood clots, increase the clearance of blood from the ventricles and hence improve outcome. ⋯ There is anecdotal evidence suggesting that the intraventricular administration of fibrinolytic agents in intraventricular hemorrhage maybe of therapeutic value and safe. Thus far, there are no randomised trials of sufficient size and quality to evaluate the safety and efficacy of this treatment modality.

ReviewBisphosphonates for the relief of pain secondary to bone metastases.
Bisphosphonates form part of standard therapy for hypercalcemia and the prevention of skeletal events in some cancers. However, the role of bisphosphonates in pain relief for bony metastases remains uncertain. ⋯ There is evidence to support the effectiveness of bisphosphonates in providing some pain relief for bone metastases. There is insufficient evidence to recommend bisphosphonates for immediate effect; as first line therapy; to define the most effective bisphosphonates or their relative effectiveness for different primary neoplasms. Bisphosphonates should be considered where analgesics and/or radiotherapy are inadequate for the management of painful bone metastases.

ReviewRiluzole for amyotrophic lateral sclerosis (ALS)/motor neuron disease (MND).
Riluzole has been approved for treatment of patients with amyotrophic lateral sclerosis in many countries but not all. Questions persist about its clinical utility because of high cost, modest efficacy and concern over adverse effects. ⋯ Riluzole 100 mg daily is reasonably safe and probably prolongs survival by about two months in patients with amyotrophic lateral sclerosis. More studies are needed, especially to clarify its effect in older patients (over 75 years), and those with more advanced disease.

ReviewPre-operative endometrial thinning agents before endometrial destruction for heavy menstrual bleeding.
Menorrhagia is one of the most common reasons for pre-menopausal women to be referred to a gynaecologist. Although medical therapy is generally the first approach, many women will eventually require or request a hysterectomy. Hysterectomy is associated with a significant in-patient hospital stay and a period of convalescence that makes it an unattractive and unnecessarily invasive option for many women. Hysteroscopic endometrial ablation or resection, and more recently "second generation" devices such as balloon or microwave ablation offer a day-case surgical alternative to hysterectomy for these women. They are also cheaper procedures than hysterectomy. Complete endometrial removal or destruction is one of the most important determinants of treatment success. Therefore surgery will be most effective if undertaken when endometrial thickness is less than four mm, in the immediate post-menstrual phase, however there are often difficulties in reliably arranging surgery for this time. The other option is the use of hormonal agents which induce endometrial thinning or atrophy prior to surgery. The most commonly evaluated agents have been goserelin (a GnRH analogue) and danazol. Progestogens and other GnRH analogues have also been studied although less data are available. It has been suggested that the use of these agents, particularly GnRH analogues, will reduce operating time, improve the intra-uterine operating environment, and reduce distension medium absorption (this is the fluid used to distend the uterine cavity during surgery). They may also result in a greater improvement in long term outcomes such as menstrual loss and dysmenorrhoea. ⋯ Endometrial thinning prior to hysteroscopic surgery in the early proliferative phase of the menstrual cycle for menorrhagia improves both the operating conditions for the surgeon and short term post-operative outcome. Gonadotrophin-releasing hormone analogues produce slightly more consistent endometrial thinning than danazol, though both agents produce satisfactory results. The effect of these agents on longer term post-operative outcomes such as amenorrhoea and the need for further surgical intervention reduces with time.
