Epilepsy is a common neurological condition, with an estimated incidence of 50 per 100,000 persons. People with epilepsy may present with various types of immunological abnormalities, such as low serum IgA level, lack of IgG subclass and identification of certain types of antibodies. Intravenous immunoglobulin (IVIg) treatment may represent a valuable approach and its efficacy has important implications for epilepsy management. ⋯ No reliable conclusions can be drawn regarding the efficacy of IVIg as a treatment for epilepsy. Further randomized controlled trials are needed.

ReviewEnteral tube feeding for amyotrophic lateral sclerosis/motor neuron disease.
Enteral feeding (tube feeding) is offered to many people with amyotrophic lateral sclerosis/motor neuron disease experiencing difficulty swallowing (dysphagia) and maintaining adequate nutritional intake leading to weight loss. ⋯ There are no randomised controlled trials to indicate whether enteral tube feeding is beneficial compared to continuation of oral feeding for any of the outcome measures. The 'best' evidence to date suggests a survival advantage for some people with amyotrophic lateral sclerosis/motor neuron disease, but these conclusions are tentative. Evidence for improved nutrition is also incomplete but tentatively favorable. Quality of life has been addressed in studies and needs more attention. Based on a number of recent non-randomized studies comparing surgical and radiographic approaches to feeding tube insertion these two procedures for PEG tube insertion appear to be equivalent.

ReviewSperm washing to prevent HIV transmission from HIV-infected men but allowing conception in sero-discordant couples.
Sperm washing is a term used to describe the process in which individual spermatozoa are separated from the seminal fluid. Sperm washing is used to prevent HIV transmission but allow conception in sero-discordant couples, where the male is HIV positive, but the female is HIV negative. This procedure is based on the observation that HIV cannot attach itself to spermatozoa, but it can be found in the fluid and cells surrounding spermatozoa. ⋯ Reports on the use of sperm washing to prevent HIV transmission from HIV infected men but allowing conception in sero-discordant couples is currently limited to observational studies. No randomised controlled trial has assessed the benefit or risk of sperm washing to prevent HIV transmission from HIV infected men but allow conception in sero-discordant couples. Thus, this systematic review identifies the need for a multicentre randomised controlled trial assessing the benefits and possible risks of sperm washing in preventing HIV transmission from HIV infected men but allow conception in sero-discordant couples.

Review Meta AnalysisMedical methods for mid-trimester termination of pregnancy.
With the improvement of ultrasound technology, the likelihood of detection of major fetal structural anomalies in mid-pregnancy has increased considerably. Upon the detection of serious anomalies, women typically are offered the option of pregnancy termination. Additionally, there are still many reasons other than fetal anomalies why women seek abortion in the mid-trimester. ⋯ Medical abortion in the second trimester using the combination of mifepristone and misoprostol appeared to have the highest efficacy and shortest abortion time interval. Where mifepristone is not available, misoprostol alone is a reasonable alternative. The optimal route for administering misoprostol is vaginally, preferably using tablets at 3-hourly intervals. Apart from pain, the side-effects of vaginal misoprostol are usually mild and self limiting. Conclusions from this review are limited by the gestational age ranges and variable medical regimens, including dosing, administrative routes and intervals of medication, of the included trials.

Review Meta AnalysisPreoperative intra aortic balloon pumps in patients undergoing coronary artery bypass grafting.
The intra aortic balloon pump (IABP) is a mechanical assist device which improves cardiac function. The device has a well-established place in algorithms for managing low cardiac output following cardiac surgery. There is increasing evidence that certain cardiac surgery patients benefit from a period of preoperative augmentation with the intra aortic balloon pump. ⋯ Evidence suggests that preoperative IABP may have a beneficial effect on mortality and morbidity in specific high risk patient groups undergoing coronary artery bypass grafting, however there are many problems with the quality, validity and generalisability of the trials. However, the available evidence is not robust enough to extend the use of IABP to truly elective, high risk patients. Defining more precisely which patient groups may benefit would be the challenge for the future.
